Actual results may differ materially from those contained in any forward-looking statements.

Overview of Business

For a discussion about our business lines, our reportable segment, and our firm, see Item 1. "Business."

Business Environment

Economic and Market Conditions

Economic Conditions. As a global investment firm, we are affected by financial and economic conditions globally. Global and regional economic conditions have a substantial impact on our financial condition and results of operations, impacting the values of the investments we make, our ability to exit these investments profitably, our ability to raise capital from investors, and our ability to make new investments. Financial and economic conditions in the United States, European Union, Japan, China, and other major economies are significant contributors to the global economy.

As of December 31, 2018, key economic indicators of U.S. economic growth, including GDP growth, unemployment and inflation, remained at healthy levels despite the volatility of the U.S. stock market at the end of 2018. However, economic projections presented at a meeting of the Federal Open Market Committee in December 2018 signaled an expected slow-down in U.S. GDP growth in 2019 compared to 2018. The U.S. Federal Reserve suspended its plans to continue raising its benchmark interest rate and held the rate steady in January 2019, after four rate increases in 2018. In the United States, real GDP growth is estimated to be 2.9% for the full year ended December 31, 2018, compared to 2.2% in the prior year; the U.S. unemployment rate was 3.9% as of December 31, 2018, down from 4.1% as of December 31, 2017; U.S. core consumer price index was 2.2% on a year-over-year basis as of December 31, 2018, up from 1.8% on a year-over-year basis as of December 31, 2017; and the effective federal funds rate set by the U.S. Federal Reserve was 2.4% as of December 31, 2018, up from 1.3% as of December 31, 2017.

As of December 31, 2018, the European Union showed signs of slow-down in economic growth, with concerns of a potential recession in Italy and rising uncertainty over the terms of Britain's exit from the European Union. The European Central Bank decided to end its quantitative easing program at the end of December 2018, which added to the concern about the slowing economic growth in the region. In the Euro Area, real GDP growth is estimated to be 1.9% for the year ended December 31, 2018 down from 2.4% in the prior year; the Euro Area unemployment rate was 7.9% as of December 31, 2018, down from 8.6% as of December 31, 2017; Euro Area core inflation was 1.0% on a year-over-year basis as of December 31, 2018, up from 0.9% as of December 31, 2017; and the short-term benchmark interest rate set by the European Central Bank was 0.0% as of December 31, 2018, unchanged from December 31, 2017.

As of December 31, 2018, the Bank of Japan maintained its accommodative monetary policy and projected a continued "expanding trend" for the economy through 2020. Chinese economic growth slowed during the fourth quarter of 2018 amid China's ongoing trade conflicts with the United States. In Japan, the short-term benchmark interest rate set by the Bank of Japan was -0.1% as of December 31, 2018, unchanged from December 31, 2017; and in China, reported real GDP is estimated to be 6.6% in the year ended December 31, 2018, below the 6.8% reported for the year ended December 31, 2017.

These and other key issues could have repercussions across regional and global financial markets, which could adversely affect the valuations of our investments. Other key issues include (i) political uncertainty caused by, among other things, populist political parties and economic nationalist sentiments, (ii) regulatory changes regarding, for example, taxation, international trade, cross-border investments, immigration, and austerity programs, (iii) increased volatility in stock markets, (iv) the U.S. Federal Reserve potentially raising its benchmark interest rates again and (v) technological advancements and innovations that may disrupt marketplaces and businesses. For a further discussion of how market conditions may affect our businesses, see "Risk Factors—Risks Related to Our Business—Difficult market and economic conditions can adversely affect our business in many ways, including by reducing the value or performance of the investments that we manage or by reducing

the ability of our funds to raise or deploy capital, each of which could negatively impact our net income and cash flow and adversely affect our financial condition."

Equity and Credit Markets. Global equity and credit markets have a substantial effect on our financial condition and results of operations. In general, a climate of reasonable interest rates and high levels of liquidity in the debt and equity capital markets provide a positive environment for us to generate attractive investment returns, which also impacts our ability to generate incentive fees and carried interest. Periods of volatility and dislocation in the capital markets present substantial risks, but also can present us with opportunities to invest at reduced valuations that position us for future growth and investment returns. Low interest rates related to monetary stimulus and economic stagnation may negatively impact expected returns on all types of investments. Higher interest rates in conjunction with slower growth or weaker currencies in some emerging market economies have caused, and may further cause, the default risk of these countries to increase, and this could impact the operations or value of our investments that operate in these regions. Areas such as Japan, which have ongoing central bank quantitative easing campaigns and comparatively low interest rates relative to the United States, could potentially experience further currency volatility and weakness relative to the U.S. dollar.

Many of our investments are in equities, so a change in global equity prices or in market volatility directly impacts the value of our investments and our profitability as well as our ability to realize investment gains and the receptiveness of fund investors to our investment products. For the year ended December 31, 2018, global equity markets were negative, with the S&P 500 Index down 4.4% and the MSCI World Index down 8.2% on a total return basis including dividends. Equity market volatility as evidenced by the Chicago Board Options Exchange Market Volatility Index (the "VIX"), a measure of volatility, ended at 25.4 as of December 31, 2018, increasing from 11.0 as of December 31, 2017. However, since December 31, 2018, the U.S. equity market has experienced a significant rebound, coinciding with a decrease in volatility. For a discussion of our valuation methods, see "Risk Factors—Risks Related to the Assets We Manage—Our investments are impacted by various economic conditions that are difficult to quantify or predict, which may have a significant impact on the valuation of our investments and, therefore, on the investment income we realize and our results of operations and financial condition" and "—Critical Accounting Policies—Fair Value Measurements—Level III Valuation Methodologies."

Many of our investments are also in non-investment grade credit instruments, and our funds and our portfolio companies also rely on credit financing and the ability to refinance existing debt. Consequently, any decrease in the value of credit instruments that we have invested in or any increase in the cost of credit financing reduces our returns and decreases our net income. In particular due in part to holdings of credit instruments such as CLOs on our balance sheet, the performance of the credit markets has had an amplified impact on our financial results, as we directly bear the full extent of losses from credit instruments on our balance sheet. Credit markets can also impact valuations because a discounted cash flow analysis is generally used as one of the methodologies to ascertain the fair value of our investments that do not have readily observable market prices. In addition, with respect to our credit instruments, tightening credit spreads are generally expected to lead to an increase, and widening credit spreads are generally expected to lead to a decrease, in the value of these credit investments, if not offset by hedging or other factors. In addition, the significant widening of credit spreads is also typically expected to negatively impact equity markets, which in turn would negatively impact our portfolio and us as noted above. During the year ended December 31, 2018, U.S. investment grade corporate bond spreads (BofA Merrill Lynch US Corporate Index) widened by 60 basis points and U.S. high-yield corporate bond spreads (BofAML HY Master II Index) widened by 170 basis points. The non-investment grade credit indices were mixed during the year ended December 31, 2018, with the S&P/LSTA Leveraged Loan Index up 0.4% and the BofAML HY Master II Index down 2.3%. During the year ended December 31, 2018, 10-year government bond yields rose 28 basis points in the United States, rose 9 basis points in the United Kingdom, fell 19 basis points in Germany, fell 58 basis points in China, and fell 5 basis points in Japan. For a further discussion of how market conditions may affect our businesses, see "Risk Factors—Risks Related to Our Business—Difficult market and economic conditions can adversely affect our business in many ways, including by reducing the value or performance of the investments that we manage or by reducing the ability of our funds to raise or deploy capital, each of which could negatively impact our net income and cash flow and adversely affect our financial condition" and "Risk Factors—Risks Related to the Assets We Manage—Our investments are impacted by various economic conditions that are difficult to quantify or predict, which may have a significant impact on the valuation of our investments and, therefore, on the investment income we realize and our results of operations and financial condition."

For further discussion of the impact of global credit markets on our financial condition and results of operations, see "Risk Factors—Risks Related to the Assets We Manage—Changes in the debt financing markets may negatively impact the ability of our investment funds, their portfolio companies and strategies pursued with our balance sheet assets to obtain attractive financing for their investments or to refinance existing debt and may increase the cost of such financing or refinancing if it is obtained, which could lead to lower-yielding investments and potentially decrease our net income," "Risk Factors—Risks Related to the Assets We Manage—Our investments are impacted by various economic conditions that are difficult to quantify or predict, which may have a significant impact on the valuation of our investments and, therefore, on the investment income

we realize and our results of operations and financial condition" and "Risk Factors—Risks Related to the Assets We Manage—Our funds and our firm through our balance sheet may make a limited number of investments, or investments that are concentrated in certain issuers, geographic regions or asset types, which could negatively affect our performance or the performance of our funds to the extent those concentrated assets perform poorly." For a further discussion of our valuation methods, see "—Critical Accounting Policies—Fair Value Measurements—Level III Valuation Methodologies."

Foreign Exchange Rates. Foreign exchange rates have a substantial impact on the valuations of our investments that are denominated in currencies other than the U.S. dollar. Currency volatility can also affect our businesses and investments that deal in cross-border trade. The appreciation or depreciation of the U.S. dollar is expected to contribute to a decrease or increase, respectively, in the U.S. dollar value of our non-U.S. investments to the extent unhedged. In addition, an appreciating U.S. dollar would be expected to make the exports of U.S. based companies less competitive, which may lead to a decline in their export revenues, if any, while a depreciating U.S. dollar would be expected to have the opposite effect. Moreover, when selecting investments for our investment funds that are denominated in U.S. dollars, an appreciating U.S. dollar may create opportunities to invest at more attractive U.S. dollar prices in certain countries outside of the United States, while a depreciating U.S. dollar would be expected to have the opposite effect. For our investments denominated in currencies other than the U.S. dollar, the depreciation in such currencies will generally contribute to the decrease in the valuation of such investments, to the extent unhedged, and adversely affect the U.S. dollar equivalent revenues of portfolio companies with substantial revenues denominated in such currencies, while the appreciation in such currencies would be expected to have the opposite effect. For the year ended December 31, 2018, the euro fell 4.5%, the British pound fell 5.6%, the Japanese yen rose 2.7%, and the Chinese renminbi fell 5.4%, respectively, relative to the U.S. dollar. For additional information regarding our foreign exchange rate risk, see "—Quantitative and Qualitative Disclosure About Market Risk—Exchange Rate Risk."

Commodity Markets. Our Private Markets portfolio contains energy real asset investments, and certain of our other Private Markets and Public Markets strategies and products, including private equity, direct lending, special situations and CLOs, also have meaningful investments in the energy sector. The value of these investments is heavily influenced by the price of natural gas and oil. During the year ended December 31, 2018, the long-term price of WTI crude oil decreased approximately 6%, while the long-term price of natural gas decreased approximately 8%. The long-term price of WTI crude oil decreased from approximately $53 per barrel to $50 per barrel, and the long-term price of natural gas decreased from approximately $2.82 per mcf to $2.60 per mcf as of December 31, 2017 and December 31, 2018, respectively. When commodity prices decline or if a decline is not offset by other factors, we would expect the value of our energy real asset investments to be adversely impacted, to the extent unhedged. In addition, because we hold certain energy assets, which had a fair value of $0.7 billion as of December 31, 2018 on our balance sheet, these price movements would have an amplified impact on our financial results, to the extent unhedged, as we would directly bear the full extent of such gains or losses. For additional information regarding our energy real assets, see "—Critical Accounting Policies—Fair Value Measurements—Level III Valuation Methodologies—Real Asset Investments" and "Risk Factors—Risks Related to the Assets We Manage—Our funds and our firm through our balance sheet may make a limited number of investments, or investments that are concentrated in certain issuers, geographic regions or asset types, which could negatively affect our performance or the performance of our funds to the extent those concentrated assets perform poorly."

Business Conditions

Our segment revenues consist of fees, performance income and investment income. Our ability to grow our revenues depends in part on our ability to attract new capital and investors, our successful deployment of capital including from our balance sheet and our ability to realize investments at a profit.

Our ability to attract new capital and investors. Our ability to attract new capital and investors in our funds is driven, in part, by the extent to which they continue to see the alternative asset management industry generally, and our investment products specifically, as an attractive vehicle for capital appreciation or income. Since 2010, we have expanded into strategies such as energy, infrastructure, real estate, growth equity, core, credit and, through hedge fund partnerships, hedge funds. In several of these strategies, our first time funds have begun raising successor funds, and we expect the cost of raising such successor funds to be lower. We have also reached out to new fund investors, including retail and high net worth investors. However, fundraising continues to be competitive. While our Americas Fund XII, Asian Fund III and our Real Estate Partners Americas II fund exceeded the size of their respective predecessor funds, there is no assurance that fundraises for our other flagship private equity funds or for our newer strategies and their successor funds will experience similar success. If we are unable to successfully raise comparably sized or larger funds, our AUM, FPAUM, and associated fees attributable to new capital raised in future periods may be lower than in prior years. New capital organically raised in AUM for the fiscal years ended December 31, 2018, 2017 and 2016 were $34.0 billion, $38.7 billion and $28.8 billion, respectively. See "Risk Factors—Risks Related to Our Business—Our inability to raise additional or successor funds (or raise successor funds of a comparable size as our predecessor funds) could have a material adverse impact on our business."

Our ability to successfully deploy capital. Our ability to maintain and grow our revenue base is dependent upon our ability to successfully deploy the capital available to us and participate in capital markets transactions. Greater competition, high valuations, increased overall cost of credit and other general market conditions may impact our ability to identify and execute attractive investments. Additionally, because we seek to make investments that have an ability to achieve our targeted returns while taking on a reasonable level of risk, we may experience periods of reduced investment activity. We have a long-term investment horizon and the capital deployed in any one quarter may vary significantly from the capital deployed in any other quarter or the quarterly average of capital deployed in any given year. Reduced levels of transaction activity also tends to result in reduced potential future investment gains, lower transaction fees and lower fees for our Capital Markets business line, which may earn fees in the syndication of equity or debt. Capital invested for the fiscal years ended December 31, 2018, 2017 and 2016 were $20.2 billion, $18.4 billion and $11.0 billion, respectively, and syndicated capital for the fiscal years ended December 31, 2018, 2017 and 2016 were $6.3 billion, $4.7 billion and $1.2 billion, respectively.

Our ability to realize investments. Challenging market and economic conditions may adversely affect our ability to exit and realize value from our investments and result in lower-than-expected returns. Although the equity markets are not the only means by which we exit investments, the strength and liquidity of the U.S. and relevant global equity markets generally, and the initial public offering market specifically, affect the valuation of, and our ability to successfully exit, our equity positions in our private equity portfolio companies in a timely manner. We may also realize investments through strategic sales. When financing is not available or becomes too costly, it may be more difficult to find a buyer that can successfully raise sufficient capital to purchase our investments. For the years ended December 31, 2018, 2017 and 2016, through exit activity in our investments, we realized investment income of $651.8 million, $479.7 million, and $694.4 million, respectively, and carried interest of $1.2 billion, $1.2 billion and $1.3 billion, respectively in each case on a segment basis.

Basis of Accounting

We consolidate the financial results of the KKR Group Partnerships and their consolidated entities, which include the accounts of our investment management and capital markets companies, the general partners of unconsolidated funds and vehicles, general partners of certain funds that are consolidated and their respective consolidated funds and certain other entities including certain CLOs and CMBS. We refer to CLOs and CMBS as collateralized financing entities ("CFEs").

When an entity is consolidated, we reflect the accounts of the consolidated entity, including its assets, liabilities, revenues, expenses, investment income, cash flows and other amounts, on a gross basis. While the consolidation of a consolidated fund or entity does not have an effect on the amounts of Net Income Attributable to KKR or KKR's stockholders' capital that KKR reports, the consolidation does significantly impact the financial statement presentation under GAAP. This is due to the fact that the accounts of the consolidated entities are reflected on a gross basis while the allocable share of those amounts that are attributable to third parties are reflected as single line items. The single line items in which the accounts attributable to third parties are recorded are presented as noncontrolling interests on the consolidated statements of financial condition and net income attributable to noncontrolling interests on the consolidated statements of operations.

For a further discussion of our consolidation policies, see Item 8. Financial Statements and Supplementary Data—Note 2 "Summary of Significant Accounting Policies."

Key Financial Measures Under GAAP

Revenues

Fees and Other

Fees and other consist primarily of (i) management and incentive fees from providing investment management services to unconsolidated funds, CLOs, other vehicles, and separately managed accounts; (ii) transaction fees earned in connection with successful investment transactions and from capital markets activities; (iii) monitoring fees from providing services to portfolio companies; (iv) expense reimbursements from certain investment funds and portfolio companies; (v) revenue earned by oil and gas-producing entities that are consolidated; and (vi) consulting fees earned by consolidated entities that employ non-employee operating consultants. These fees are based on the contractual terms of the governing agreements and are recognized when earned, which coincides with the period during which the related services are performed and in the case of transaction fees, upon closing of the transaction. Monitoring fees may provide for a termination payment following an initial public offering or change of control. These termination payments are recognized in the period when the related transaction closes.

Capital Allocation-Based Income

Capital allocation-based income is earned from those arrangements whereby KKR serves as general partner and includes income from KKR's capital interest as well as “carried interest” which entitles KKR to a disproportionate allocation of investment income from investment funds' limited partners.

For a further discussion of our revenue policies, see Item 8. Financial Statements and Supplementary Data—Note 2 "Summary of Significant Accounting Policies."

Expenses

Compensation and Benefits

Compensation and benefits expense includes cash compensation consisting of salaries, bonuses, and benefits, as well as equity-based compensation consisting of charges associated with the vesting of equity-based awards, carry pool allocations, and other performance-based income compensation. The amounts allocated to the carry pool and other performance-based income compensation are accounted for as compensatory profit-sharing arrangements and recorded as compensation and benefits expenses.

All employees and employees of certain consolidated entities receive a base salary that is paid by KKR or its consolidated entities, and is accounted for as compensation and benefits expense. These employees are also eligible to receive discretionary cash bonuses based on performance, overall profitability, and other matters. While cash bonuses paid to most employees are borne by KKR and certain consolidated entities and result in customary compensation and benefits expense, in the past cash bonuses that are paid to certain employees have been borne by KKR Holdings. These bonuses have historically been funded with distributions that KKR Holdings receives on KKR Group Partnership Units held by KKR Holdings but are not then passed on to holders of unvested units of KKR Holdings. Because employees are not entitled to receive distributions on units that are unvested, any amounts allocated to employees in excess of an employee's vested equity interests are reflected as employee compensation and benefits expense. These compensation charges are currently recorded based on the amount of cash expected to be paid by KKR Holdings. Because KKR makes only fixed quarterly dividends, the distributions made on KKR Group Partnership Units underlying any unvested KKR Holdings units are generally insufficient to fund annual cash bonus compensation to the same extent as in periods prior to the fourth quarter of 2015. In addition, substantially all remaining units in KKR Holdings have been allocated and, while subject to a 5 year vesting period, will become fully vested by 2021, thus decreasing the amount of distributions received by KKR Holdings that are available for annual cash bonus compensation. We, therefore, expect to pay all or substantially all of the cash bonus payments from KKR's cash from operations and the carry pool; although, from time to time, KKR Holdings may contribute to the cash bonus payments in the future. For the year ending December 31, 2018, no cash bonuses were contributed by KKR Holdings and all amounts paid were funded from other sources, including cash from our operations and the carry pool. See "Risks Related to Our Business—If we cannot retain and motivate our principals and other key personnel and recruit, retain and motivate new principals and other key personnel, our business, results and financial condition could be adversely affected" regarding the adequacy of such distributions to fund future discretionary cash bonuses.

KKR uses several methods, which are designed to yield comparable results, to allocate carried interest and other performance income compensation. With respect to KKR's investment funds that provide for carried interest without a preferred return, KKR allocates 40% of the carried interest received from such funds to its carry pool for employees and non-employee operating consultants. Beginning with the quarter ended September 30, 2016, for investment funds that provide for carried interest with a preferred return and have accrued carried interest as of June 30, 2016, KKR also includes 40% of the management fees that would have been subject to a management fee refund as performance income compensation. Because of the different ways management fees are refunded in preferred return and non-preferred return funds that provide for carried interest, this calculation of 40% of the portion of the management fees subject to refund for funds that have a preferred return is designed to allocate to compensation an amount comparable to the amount that would have been allocated to the carry pool had the fund not had a preferred return. Beginning with the quarter ended September 30, 2017, for then-current and future carry generating funds with a preferred return and no or minimal accrued carried interest as of June 30, 2017, KKR allocates 43% of the carried interest to the carry pool instead of 40% of carried interest. For impacted funds, the incremental 3% replaces the allocation of management fee refunds that would have been calculated for those funds and is designed, based on a historical financial analysis of certain investment funds, to allocate an amount for preferred return funds that is comparable to the management fee refunds that would have been allocated as performance income compensation for those funds. The percentage of carried interest, management fee refunds, and incentive fees allocable to the carry pool or as performance income compensation is subject to change from time to time. For a discussion of how management fees are refunded for preferred

return funds and non-preferred funds see "—Fair Value Measurements—Recognition of Carried Interest in the Statement of Operations."

General, Administrative and Other

General, administrative and other expense consists primarily of professional fees paid to legal advisors, accountants, advisors and consultants, insurance costs, travel and related expenses, communications and information services, depreciation and amortization charges, expenses (including impairment charges) incurred by oil and gas-producing entities that are consolidated, costs incurred in connection with pursuing potential investments that do not result in completed transactions ("broken-deal expenses"), and other general operating expenses. A portion of these general administrative and other expenses, in particular broken-deal expenses, are borne by fund investors.

Investment Income (Loss)

Net Gains (Losses) from Investment Activities

Net gains (losses) from investment activities consist of realized and unrealized gains and losses arising from our investment activities as well as income earned from certain equity method investments. Fluctuations in net gains (losses) from investment activities between reporting periods is driven primarily by changes in the fair value of our investment portfolio as well as the realization of investments. The fair value of, as well as the ability to recognize gains from, our investments is significantly impacted by the global financial markets, which, in turn, affects the net gains (losses) from investment activities recognized in any given period. Upon the disposition of an investment, previously recognized unrealized gains and losses are reversed and an offsetting realized gain or loss is recognized in the current period. Since our investments are carried at fair value, fluctuations between periods could be significant due to changes to the inputs to our valuation process over time. For a further discussion of our fair value measurements and fair value of investments, see "—Critical Accounting Policies—Fair Value Measurements."

Dividend Income

Dividend income consists primarily of distributions that we and our consolidated investment funds receive from portfolio companies in which they invest. Dividend income is recognized primarily in connection with (i) dispositions of operations by portfolio companies, (ii) distributions of cash generated from operations from portfolio investments, and (iii) other significant refinancings undertaken by portfolio investments.

Interest Income

Interest income consists primarily of interest that is received on our credit instruments in which we and our consolidated funds and other entities invest as well as interest on our cash balances and other investments.

Interest Expense

Interest expense is incurred from debt issued by KKR, including debt issued by KFN, credit facilities entered into by KKR, debt securities issued by consolidated CFEs, and financing arrangements at our consolidated funds entered into primarily with the objective of managing cash flow. KFN's debt obligations are non-recourse to KKR beyond the assets of KFN. Debt securities issued by consolidated CFEs are supported solely by the investments held at the CFE and are not collateralized by assets of any other KKR entity. Our obligations under financing arrangements at our consolidated funds are generally limited to our pro rata equity interest in such funds. However, in some circumstances, we may provide limited guarantees of the obligations of our general partners in an amount equal to its pro rata equity interest in such funds. Our management companies bear no obligations with respect to financing arrangements at our consolidated funds. We also may provide other kinds of guarantees. See "—Liquidity."

Income Taxes

On July 1, 2018, we converted from a Delaware limited partnership to a Delaware corporation. Prior to the Conversion, KKR’s investment income and carried interest generally were not subject to U.S. corporate income taxes. Subsequent to the Conversion, all income earned by KKR is subject to U.S. corporate income taxes, resulting in an overall higher income tax expense (or benefit) in periods subsequent to the Conversion.

KKR & Co. Inc. is a corporation for U.S. federal income tax purposes and thus is subject to U.S. federal, state and local corporate income taxes at the entity level on KKR’s share of net taxable income. In addition, the KKR Group Partnerships and certain of their subsidiaries operate in the United States as partnerships for U.S. federal income tax purposes and as corporate entities in certain non-U.S. jurisdictions. These entities, in some cases, are subject to U.S. state or local income taxes or non-U.S. income taxes.

As a result of the Conversion, KKR recognized a partial step-up in the tax basis of certain assets that will be recovered as those assets are sold or the basis is amortized. On the date of the Conversion, we recorded an estimated net tax benefit and estimated net deferred tax asset of $257.1 million relating to this partial step-up in tax basis. The actual amount of the partial step-up in tax basis when it is finally determined is expected to differ, possibly materially, from the current estimate, which in turn is expected to cause our income tax provision and effective tax rate under GAAP to differ, possibly to a material extent, from the current estimate. See Item 8. Financial Statements and Supplementary Data—Note 11 "Income Taxes."

Tax laws are complex and subject to different interpretations by the taxpayer and respective governmental taxing authorities. Significant judgment is required in determining tax expense and in evaluating tax positions including evaluating uncertainties. We review our tax positions quarterly and adjust our tax balances as new information becomes available.

For a further discussion of our income tax policies, see Item 8. Financial Statements and Supplementary Data—Note 2 "Summary of Significant Accounting Policies" and Note 11 "Income Taxes."

Net Income (Loss) Attributable to Noncontrolling Interests

Net income (loss) attributable to noncontrolling interests primarily represents the ownership interests that certain third parties hold in entities that are consolidated in the financial statements as well as the ownership interests in our KKR Group Partnerships that are held by KKR Holdings. The allocable share of income and expense attributable to these interests is accounted for as net income (loss) attributable to noncontrolling interests. Given the consolidation of certain of our investment funds and the significant ownership interests in our KKR Group Partnerships held by KKR Holdings, we expect a portion of net income (loss) will continue to be attributed to noncontrolling interests in our business.

For a further discussion of our noncontrolling interests policies, see Item 8. Financial Statements and Supplementary Data—Note 2 "Summary of Significant Accounting Policies."

Key Segment and Other Operating and Performance Measures

The key performance measures that follow are used by management in making operational and resource deployment decisions as well as assessing the overall performance of KKR's businesses. KKR's segment reporting is presented prior to giving effect to the allocation of income (loss) between KKR & Co. Inc. and KKR Holdings L.P. and as such represents the business in total. In addition, KKR's segment reporting is presented without giving effect to the consolidation of the investment funds and CFEs that KKR manages as well as other consolidated entities that are not subsidiaries of KKR & Co. Inc.

We disclose certain financial measures in this report that are calculated and presented using methodologies other than in accordance with GAAP. We believe that providing these performance measures on a supplemental basis to our GAAP results is helpful to stockholders in assessing the overall performance of KKR's businesses. These financial measures should not be considered as a substitute for similar financial measures calculated in accordance with GAAP, if available. We caution readers that these non-GAAP financial measures may differ from the calculations of other investment managers, and as a result, may not be comparable to similar measures presented by other investment managers. Reconciliations of these non-GAAP financial measures to the most directly comparable financial measures calculated and presented in accordance with GAAP, where applicable, are included within Item 8. Financial Statements and Supplementary Data—Note 14 "Segment Reporting" and under "—Segment Balance Sheet."

Adjusted Shares

Adjusted shares are used as a measure of the total common equity ownership of KKR that is held by KKR & Co. Inc. (including equity awards issued under the Amended and Restated KKR & Co. Inc. 2010 Equity Incentive Plan (the "Equity Incentive Plan"), but excluding preferred stock), KKR Holdings and other holders of securities exchangeable into Class A common stock of KKR & Co. Inc. and represent the fully diluted share count of Class A common stock using the if-converted method. We believe this measure is useful to stockholders as it provides an indication of the total common equity ownership of KKR as if all outstanding KKR Holdings units, equity awards issued under the Equity Incentive Plan and other exchangeable securities had been exchanged for Class A common stock of KKR & Co. Inc. The 6.75% Series A Preferred Stock ("Series A Preferred Stock") and 6.50% Series B Preferred Stock ("Series B Preferred Stock") are not exchangeable for Class A common stock of KKR & Co. Inc.

Adjusted Shares Eligible for Distribution

Adjusted shares eligible for distribution represents the portion of total adjusted shares that are eligible to receive a dividend. We believe this measure is useful to stockholders as it provides insight into the calculation of amounts available for distribution as dividends on a per share basis. Weighted average adjusted shares eligible for distribution is used in the calculation of after-tax distributable earnings per share.

After-tax Distributable Earnings

After-tax distributable earnings is a performance measure of KKR’s earnings on a segment basis excluding mark-to-market gains (losses). Starting with the second quarter of 2018, it is defined as the amount of net realized earnings of KKR for a given reporting period, after deducting equity-based compensation. KKR revised the definition of after-tax distributable earnings starting in the second quarter of 2018, because it reflects how the chief operating decision makers allocate resources and assess performance of KKR’s business. KKR believes that after-tax distributable earnings is useful to stockholders as it aligns KKR’s net realization performance with the manner in which KKR receives its revenues and determines the compensation of its employees. After-tax distributable earnings does not represent and is not used to calculate actual dividends under KKR’s dividend policy. Historically, equity-based compensation expense relating to the Equity Incentive Plan was not reflected in our calculation of after-tax distributable earnings. Under KKR’s segment presentation, equity-based compensation expense is included in after-tax distributable earnings as a component of compensation expense in order to reflect the dilutive nature of these non-cash equity-based awards. For comparability, after-tax distributable earnings for the comparable prior periods have been calculated using this definition.

Assets Under Management ("AUM")

Assets under management represent the assets managed or advised by KKR from which KKR is entitled to receive fees or a carried interest (either currently or upon deployment of capital), general partner capital, and assets managed or advised by strategic BDC partnership and hedge fund managers in which KKR holds a minority ownership interest. We believe this measure is useful to stockholders as it provides additional insight into the capital raising activities of KKR and its hedge fund managers and the overall activity in their investment funds and other managed capital. KKR calculates the amount of AUM as

of any date as the sum of: (i) the fair value of the investments of KKR's investment funds; (ii) uncalled capital commitments from these funds, including uncalled capital commitments from which KKR is currently not earning management fees or carried interest; (iii) the fair value of investments in KKR's co-investment vehicles; (iv) the par value of outstanding CLOs (excluding CLOs wholly-owned by KKR); (v) KKR's pro rata portion of the AUM of hedge fund managers in which KKR holds a minority ownership interest; (vi) all AUM of the strategic BDC partnership with FS Investments; and (vii) the fair value of other assets managed by KKR. The pro rata portion of the AUM of hedge fund managers is calculated based on KKR’s percentage ownership interest in such entities multiplied by such entity’s respective AUM. KKR's definition of AUM is not based on any definition of AUM that may be set forth in the agreements governing the investment funds, vehicles or accounts that it manages or calculated pursuant to any regulatory definitions.

Book Value

Book value is a measure of the net assets of KKR’s reportable segment and is used by management primarily in assessing the unrealized value of KKR’s investments and other assets, including carried interest. We believe this measure is useful to stockholders as it provides additional insight into the assets and liabilities of KKR excluding the assets and liabilities that are allocated to noncontrolling interest holders and to the holders of the Series A and Series B Preferred Stock. As of September 30, 2018 and following the Conversion, KKR's segment balance sheet reflects KKR's tax assets and liabilities as prepared under GAAP.

Capital Invested

Capital invested is the aggregate amount of capital invested by (i) KKR’s investment funds, (ii) KKR's Principal Activities business line as a co-investment, if any, alongside KKR’s investment funds, and (iii) KKR's Principal Activities business line in connection with a syndication transaction conducted by KKR's Capital Markets business line, if any. Capital invested is used as a measure of investment activity at KKR during a given period. We believe this measure is useful to stockholders as it provides a measure of capital deployment across KKR’s business lines. Capital invested includes investments made using investment financing arrangements like credit facilities, as applicable. Capital invested excludes (i) investments in certain leveraged credit strategies, (ii) capital invested by KKR’s Principal Activities business line that is not a co-investment alongside KKR’s investment funds, and (iii) capital invested by KKR’s Principal Activities business line that is not invested in connection with a syndication transaction by KKR’s Capital Markets business line. Capital syndicated by KKR's Capital Markets business line to third parties other than KKR’s investment funds or Principal Activities business line is not included in capital invested. See also "—Syndicated Capital."

Fee Paying AUM ("FPAUM")

Fee paying AUM ("FPAUM") represents only the AUM from which KKR receives management fees. We believe this measure is useful to stockholders as it provides additional insight into the capital base upon which KKR earns management fees. FPAUM is the sum of all of the individual fee bases that are used to calculate KKR's and its hedge fund and BDC partnership management fees and differs from AUM in the following respects: (i) assets and commitments from which KKR does not receive a management fee are excluded (e.g., assets and commitments with respect to which it receives only carried interest or is otherwise not currently receiving a management fee) and (ii) certain assets, primarily in its private equity funds, are reflected based on capital commitments and invested capital as opposed to fair value because fees are not impacted by changes in the fair value of underlying investments.

Fee Related Earnings ("FRE")

Fee related earnings is a supplemental measure of earnings of KKR on a segment basis before performance income and investment income. KKR believes this measure may be useful to stockholders as it provides additional insight into the profitability of KKR’s fee generating management companies and capital markets businesses. Starting with the second quarter of 2018, fee related earnings is calculated as KKR’s total Fees and Other, Net, multiplied by KKR’s segment operating margin. For purposes of the fee related earnings calculation, segment operating margin is calculated as Segment Operating Earnings, before equity-based compensation, divided by total segment revenues. Historically, fee related earnings was calculated as operating earnings of KKR on a segment basis before performance income, related performance income compensation and investment income. KKR revised the definition of fee related earnings starting in the second quarter of 2018 to provide supplemental information about fees generated from KKR’s management companies and capital markets business because KKR believes it provides increased transparency on KKR’s underlying financial results to the stockholders. Fee related earnings for the comparable prior periods have been calculated using this definition.

Income Taxes Paid

Income taxes paid represents the estimated total tax impact on KKR’s distributable earnings before taxes. This amount is the implied amount of income taxes that would be paid assuming that all pre-tax distributable earnings were allocated to KKR & Co. Inc., which would occur following an exchange of all KKR Holdings units for Class A common stock of KKR & Co. Inc.

Outstanding Adjusted Shares

Outstanding adjusted shares represents the portion of total adjusted shares that would receive assets of KKR if it were to be liquidated as of a particular date. Outstanding adjusted shares is used to calculate book value per outstanding adjusted share, which we believe is useful to stockholders as it provides a measure of net assets of KKR’s reportable segment on a per share basis.

Segment Operating Earnings

Segment operating earnings represents segment earnings before interest expense, preferred dividends, income attributable to noncontrolling interests and income taxes paid. We believe segment operating earnings is useful to stockholders as it provides a supplemental measure of our operating performance without taking into account items that we do not believe relate directly to operations.

Syndicated Capital

Syndicated capital is the aggregate amount of capital in transactions originated by KKR and its investment funds and carry-yielding co-investment vehicles, which has been distributed to third parties, generally in exchange for a fee. It does not include (i) capital invested in such transactions by KKR investment funds and carry-yielding co-investment vehicles, which is instead reported in capital invested, (ii) debt capital that is arranged as part of the acquisition financing of transactions originated by KKR investment funds, and (iii) debt capital that is either underwritten or arranged on a best efforts basis. Syndicated capital is used as a measure of investment activity for KKR during a given period, and we believe that this measure is useful to stockholders as it provides additional insight into levels of syndication activity in KKR's Capital Markets business line and across KKR's investment platform.

Uncalled Commitments

Uncalled commitments are used as a measure of unfunded capital commitments that KKR’s investment funds and carry-paying co-investment vehicles have received from partners to contribute capital to fund future investments. We believe this measure is useful to stockholders as it provides additional insight into the amount of capital that is available to KKR’s investment funds to make future investments. Uncalled commitments are not reduced for investments completed using fund-level investment financing arrangements.

Total Revenues$2,395,836$3,557,280$(1,161,444)

Prior to January 1, 2018, to the extent an investment fund was not consolidated, KKR accounted for carried interest within Fees and Other separately from its general partner capital interest, which was included in Net Gains (Losses) from Investment Activities in the consolidated statements of operations. Effective January 1, 2018, the carried interest component of the general partner interest and the capital interest KKR holds in its investment funds as the general partner are accounted for as a single unit of account and reported in capital allocation-based income within Revenues in the consolidated statements of operations. This change in accounting principle has been applied on a full retrospective basis. See Note 2 "Summary of Significant Accounting Policies" to the consolidated financial statements included elsewhere in this report.

Total Fees and Other for the year ended December 31, 2018 increased compared to the year ended December 31, 2017 primarily as a result of an increase in transaction fees, management fees and expense reimbursements, and a decrease in fee credits. Fee credits owed to consolidated investment funds are eliminated upon consolidation under GAAP. Transaction and monitoring fees earned that generate these fee credits are not eliminated upon consolidation because those fees are earned from KKR portfolio companies which are not consolidated. Accordingly, certain transaction and monitoring fees are reflected in revenues without a corresponding fee credit. These increases were partially offset by a decrease in oil and gas revenue.

For a more detailed discussion of the factors that affected our transaction fees and monitoring fees during the period, see "—Segment Results—Segment Revenues."

The increase in management fees during the year ended December 31, 2018 compared to the prior period was due primarily to management fees earned from our Asian Fund III and Global Infrastructure Investors III Fund which entered their investment periods in the second quarter of 2017 and the second quarter of 2018, respectively. This increase was partially offset by a reduction in management fees from (i) our BDC platform as a result of the FS Investments Transaction that closed in the second quarter of 2018, as is further explained in the next paragraph, (ii) Prisma Capital Partners LP ("Prisma") as a result of the transaction to combine Pacific Alternative Asset Management Company, LLC ("PAAMCO") and Prisma to create PAAMCO Prisma (the "PAAMCO Prisma transaction") that closed in the second quarter of 2017, as is further explained in the next paragraph, (iii) lower management fees calculated based on lower levels of invested capital as a result of realizations primarily in our European Fund III, 2006 Fund and Asian Fund and (iv) lower management fees paid by our Asian Fund II when it entered its post-investment period in the second quarter of 2017, in which it pays fees at a lower rate than during the investment period and based on capital invested at the time rather than total committed capital.

KKR reports its investment in FS/KKR Advisor and PAAMCO Prisma using the equity method of accounting, and as such, KKR reflects its allocation of the net income of these entities as investment income. Accordingly, the management fees of the BDCs and Prisma that had been reported in management fee revenues prior to the closing of the transactions described above are now reflected on a net basis as part of our allocation of the net income of these entities in 2018 resulting in a decrease in our reported gross management fees when compared to the prior period.

The decrease in carried interest and general partner capital interest during the year ended December 31, 2018 compared to the prior period was due primarily to a lower level of net appreciation in the value of our private equity investment portfolio as compared to the year ended December 31, 2017.

Compensation and Benefits Expenses

The decrease was primarily due to a decrease in compensation resulting from a lower level of net carried interest in our investment funds as compared to the prior period. Partially offsetting this decrease was an increase in other compensation due to a higher level of fees during the year ended December 31, 2018 compared to the year ended December 31, 2017 as well as higher equity-based compensation charges resulting from an increase in the weighted average number of unvested shares outstanding.

General, Administrative and Other Expenses

The increase for the year ended December 31, 2018 compared to the year ended December 31, 2017 was primarily due to (i) an increase in professional fees and travel expenses incurred, the most significant of which were professional fees incurred in connection with the Conversion, (ii) an increase in expenses reimbursable by investment funds, (iii) a higher level of expenses that are creditable to our investment funds, which includes broken-deal expenses and (vi) a higher level of financing costs incurred related to debt at new consolidated CLOs as compared to the prior period. These increases were partially offset by (i) a decrease in depreciation, depletion and amortization of our consolidated oil and gas-producing entities compared to the prior period primarily caused by lower production and the sale of an oil and gas producing entity during the second quarter of 2018 and (ii) expenses of Prisma that had been reported on a gross basis prior to the closing of the PAAMCO Prisma transaction on June 1, 2017 and that are now reflected as part of our allocation of the net income of PAAMCO Prisma after June 1, 2017, resulting in a decrease in our reported General, Administrative and Other Expenses as compared to the prior period.

Prior to January 1, 2018, to the extent an investment fund was not consolidated, KKR accounted for its general partner capital interest in Net Gains (Losses) from Investment Activities in the consolidated statements of operations. Effective January 1, 2018, the general partner capital interest and the carried interest component of the general partner interest are accounted for as a single unit of account and reported within Revenues in the consolidated statements of operations. This change in accounting has been applied on a full retrospective basis. See Item 8. Financial Statements and Supplementary Data—Note 2 "Summary of Significant Accounting Policies."

Net Gains (Losses) from Investment Activities for the year ended December 31, 2018

The net gains from investment activities for the year ended December 31, 2018 were comprised of net realized gains of $534.7 million and net unrealized gains of $720.2 million.

Realized Gains from Investment Activities

For the year ended December 31, 2018, realized gains related primarily to (i) the sale of assets in our consolidated special situations funds, (ii) the FS Investments Transaction, (iii) the sale of our equity interest in Nephila, (iv) the sale of real estate investments held through certain consolidated entities, and (v) the partial sale of our investment in First Data Corporation (NYSE: FDC) in the third quarter of 2018 which is held in part as a direct co-investment by KKR.

Realized Losses from Investment Activities

Partially offsetting these realized gains were realized losses primarily relating (i) the write-off of Trinity Holdings LLC (energy sector) and certain CLOs during the year ended December 31, 2018 and (ii) the partial write-off of our investment in Preferred Proppants, LLC (manufacturing sector) which is held directly by KKR and in our consolidated special situations funds.

Unrealized Gains from Investment Activities

For the year ended December 31, 2018, unrealized gains were driven primarily by (i) mark-to-market gains in portfolio companies in our core investment strategy, the most significant of which were USI, Inc. (financial services sector), PetVet Care Centers, LLC (health care sector), and Heartland Dental LLC (health care sector), (ii) mark-to-market gains in our growth equity investments held directly by KKR and certain consolidated entities, (iii) an increase in our allocation of the net income of our hedge fund partnerships and BDC platform, (iv) the reversal of previously recognized unrealized losses related to the write-off of Trinity Holdings LLC and certain CLOs and the partial write-off of Preferred Proppants, LLC as described above, and (v) mark-to-market gains on investments in our energy portfolio held through certain consolidated funds.

Unrealized Losses from Investment Activities

Partially offsetting the unrealized gains above were unrealized losses relating to (i) the reversal of previously recognized unrealized gains relating to assets sold in our consolidated special situations funds, the partial sale of First Data Corporation in the third quarter of 2018 which is held as a direct co-investment by KKR and the sale of real estate investments held through certain consolidated entities and (ii) mark-to-market losses on certain investments held in our consolidated special situations funds and investments held at our India debt financing company.

For a discussion of other factors that affected KKR's realized investment income, see "—Segment Analysis." For a detailed discussion of the factors that affected our net gains (losses) from investment activities for the year ended December 31, 2017, see our discussion for the year ended December 31, 2017 compared to the year ended December 31, 2016.

Dividend Income

During the year ended December 31, 2018, the most significant dividends received included $52.7 million from our consolidated energy funds, $34.7 million from our consolidated special situations funds, and $32.4 million from our consolidated real estate funds. During the year ended December 31, 2017, the most significant dividends received included$88.5 million from our consolidated special situations funds and $43.5 million from our consolidated real estate funds. Significant dividends from portfolio companies or consolidated funds are generally not recurring quarterly dividends, and while they may occur in the future, their size and frequency are variable. For a discussion of other factors that affected KKR's dividend income, see "—Segment Results—Segment Revenues—Principal Activities Revenues—Realized Investment Income."

Interest Income

The increase in interest income during the year ended December 31, 2018 compared to the year ended December 31, 2017 was primarily due to a higher level of interest earned related to (i) the closing of seven additional consolidated CLOs subsequent to the year ended December 31, 2017, (ii) an increase in capital deployed in investments held by KREF which is consolidated and (iii) an increase in the amount of investments held in our consolidated credit funds compared to the prior period. These increases were partially offset by a decrease in interest income earned as a result of the sale of KKR's beneficial

interest in four consolidated CMBS vehicles held by KREF that resulted in the deconsolidation of such vehicles subsequent to December 31, 2017. For a discussion of other factors that affected KKR's interest income, see "—Segment Results—Segment Revenues—Principal Activities Revenues—Realized Investment Income."

Interest Expense

The increase in interest expense during the year ended December 31, 2018 compared to the year ended December 31, 2017 was primarily due to the impact of (i) the closing of seven additional consolidated CLOs subsequent to the year ended December 31, 2017, (ii) increased interest on amounts under KREF's lending facilities used to finance investments in commercial loans and (iii) increased borrowings at KFN. These increases were partially offset by a decrease in (i) interest expense incurred as a result of the sale of KKR's beneficial interest in four consolidated CMBS vehicles held by KREF that resulted in the deconsolidation of such vehicles subsequent to December 31, 2017 and (ii) interest expense associated with certain notes issued by consolidated CLOs being called for redemption subsequent to December 31, 2017. For a discussion of other factors that affected KKR's interest expense, see "—Segment Analysis—Segment Expenses—Interest Expense."

Income (Loss) Before Taxes

The decrease in income (loss) before taxes for the year ended December 31, 2018 compared to the year ended December 31, 2017 was due primarily to a lower level of carried interest and general partner capital interest, partially offset by (i) a higher level of net gains from investment activities, (ii) a higher level of fees and (iii) a lower level of compensation and benefits expense, in each case as described above.

Income Taxes

For the year ended December 31, 2018 there was a net income tax benefit of $194.1 million which was driven primarily by tax benefits recorded on the date of the Conversion. The tax benefit was partially offset by a higher level of income that is subject to corporate taxes following the Conversion. Prior to the Conversion, KKR & Co. L.P.’s investment income and carried interest generally were not subject to U.S. corporate income taxes. Subsequent to the Conversion, all income earned by KKR & Co. Inc. is subject to U.S. corporate income taxes, which we believe will result in an overall higher income tax expense (or benefit) when compared to periods prior to the Conversion. Our effective tax rate under GAAP for the year ended December 31, 2018 was (8.6)%. As a result of the Conversion KKR recognized a partial step-up in the tax basis of certain assets that will be recovered as those assets are sold or the basis is amortized. This generally results in a lower level of taxable gains upon realization of carried interest and investment income for those assets that existed on the date of the Conversion. Over time as these assets with higher tax basis are realized, we expect that our income tax expense and effective tax rate will increase. The pace of such increase is not currently known and is dependent on a variety of factors including the pace at which the assets with higher tax basis are realized and the mix of all assets realized in any given period. For a discussion of factors that impacted KKR's tax provision, see Item 8. Financial Statements and Supplementary Data—Note 2 "Summary of Significant Accounting Policies" and Note 11 "Income Taxes."

Net Income (Loss) Attributable to Noncontrolling Interests

Net income (loss) attributable to noncontrolling interests for the year ended December 31, 2018 relates primarily to net income attributable to KKR Holdings representing its ownership interests in the KKR Group Partnerships as well as third-party limited partner interests in those investment funds that we consolidate. The decrease from the prior period is due primarily to lower amounts attributed to KKR Holdings in connection with a lower level of income recognized for the year ended December 31, 2018 as compared to the prior period as well as a reduction in KKR Holdings' ownership percentage in the KKR Group Partnerships. This decrease was partially offset by a higher level of income recorded by certain consolidated fund entities that is attributable to third party limited partners.

Net Income (Loss) Attributable to KKR & Co. Inc.

The increase in net income (loss) attributable to KKR & Co. Inc. for the year ended December 31, 2018 compared to the year ended December 31, 2017 was primarily due to an overall tax benefit in the current period as compared to tax expense in the prior period as well as a higher level of net investment gains and fees, partially offset by a lower level of carried interest gains in the current period as compared to the prior period.

Total Fees and Other for the year ended December 31, 2017 increased compared to the year ended December 31, 2016 primarily as a result of an increase in transaction fees, management fees, monitoring fees and expense reimbursements. These increases were partially offset by an increase in fee credits.

For a more detailed discussion of the factors that affected our transaction fees and monitoring fees during the period, see "—Segment Results—Segment Revenues."

The increase in management fees during the year ended December 31, 2017 compared to the prior period was due primarily to management fees earned from our Americas Fund XII and Asian Fund III which entered their investment periods in the first and second quarter of 2017, respectively. This increase was partially offset by a reduction in management fees from (i) Prisma as a result of the PAAMCO Prisma transaction that closed in the second quarter of 2017 and (ii) lower management fees paid by our North America Fund XI and Asian Fund II when they entered their post-investment periods in the first and second quarter of 2017, respectively, in which they pay fees at a lower rate than during their investment periods and based on capital invested at the time rather than total committed capital.

The increase in carried interest and general partner capital interest earned during the year ended December 31, 2017 compared to the prior period was due primarily to increases in carried interest gains primarily reflecting a higher level of appreciation in the value of our private equity portfolio as compared to the prior period and to a lesser extent gains in our private credit portfolio during the year ended December 31, 2017 as compared to the year ended December 31, 2016.

Compensation and Benefits Expenses

The increase was primarily due to (i) a higher level of carry pool allocations reflecting higher appreciation in the value of our private equity and credit portfolios, (ii) an increase in cash compensation and benefits, and (iii) an increase in equity-based compensation resulting from new equity grants of KKR Holdings units during the year ended December 31, 2017 compared to the year ended December 31, 2016.

General, Administrative and Other Expenses

The increase was primarily due to (i) a reduction in the fair value of the contingent consideration liability during the year ended December 31, 2016 related to the acquisition of Prisma from $46.6 million to zero since it was determined that it was no

longer probable that the sellers of Prisma would be entitled to any future additional payment under the arrangement while no such reversal of expense was incurred during the current period and (ii) an increase in professional fees and other expenses incurred as compared to the prior period. These increases were partially offset by (i) a lower level of financing costs incurred relating to debt at new consolidated CLOs for which the fair value option has been elected, (ii) a decrease in depreciation, depletion and amortization of our consolidated oil and gas-producing entities primarily caused by a lower cost basis due to previously recorded impairments, resulting in a lower unit of production depletion rate compared to the prior period, and (iii) the write-off of intangible assets during the year ended December 31, 2016 in connection with the termination of management contracts for certain credit funds that were wound down while no such charge was incurred during the current period.

Net Gains (Losses) from Investment Activities for the year ended December 31, 2017

The net gains from investment activities for the year ended December 31, 2017 were comprised of net realized gains of $38.3 million and net unrealized gains of $889.8 million.

Realized Gains from Investment Activities

For the year ended December 31, 2017, realized gains were comprised primarily of realized gains related to the sale of private equity investments held by KKR's balance sheet, including the final sale of our investment in US Foods Holding Corp. (NYSE: USFD), HCA Holdings, Inc. (NYSE: HCA), and Galenica AG (VTX: GALN) and the partial sale of our investment in First Data Corporation.

Realized Losses from Investment Activities

Partially offsetting these realized gains were realized losses relating to (i) alternative credit assets in our consolidated special situations funds and KFN, (ii) the sale of investments held by our consolidated CLOs, and (iii) the sale of our investments in Fortune Creek Partnership (energy sector) and Aurora Eaglebine (energy sector) which are held in part by KKR's balance sheet in our energy portfolio.

Unrealized Gains from Investment Activities

For the year ended December 31, 2017, net unrealized gains were driven primarily by (i) mark-to-market gains on alternative credit assets in our consolidated special situations funds and KFN, (ii) mark-to-market gains in certain consolidated entities, the most significant of which were unrealized gains in our growth equity investments, (iii) mark-to-market gains in our private equity portfolio held by KKR's balance sheet, the most significant of which were unrealized gains in our investment in First Data Corporation, (iv) mark-to-market gains in our infrastructure portfolio held by KKR's balance sheet and (v) the reversal of unrealized losses on the sale of our investment in Fortune Creek Partnership and the restructuring of our investment in Aurora Eaglebine which are held by KKR's balance sheet in our energy portfolio. For the year ended December 31, 2017, unrealized gains from investment activities includes a gain of $67.2 million relating to a remeasurement of the tax receivable agreement liability which arises from changes in the associated deferred tax balances related to the 2017 Tax Act.

Unrealized Losses from Investment Activities

Partially offsetting the unrealized gains above were unrealized losses, the most significant of which were unrealized losses relating to (i) the reversal of unrealized gains on the final sale of our investments in US Foods Holding Corp., HCA Holdings, Inc., and Galenica AG and (ii) mark-to-market losses in certain consolidated entities, the most significant of which were unrealized losses in our growth equity investments.

For a discussion of other factors that affected KKR's realized investment income, see "—Segment Analysis."

Net Gains (Losses) from Investment Activities for the year ended December 31, 2016

The net gains from investment activities for the year ended December 31, 2016 were comprised of net realized gains of $347.1 million and net unrealized losses of $136.1 million. For the year ended December 31, 2016, net realized gains were comprised primarily of the net impact of (i) realized gains on sales of private equity investments held by KKR's balance sheet, including the partial sales of Walgreens Boots Alliance, Inc. (NASDAQ: WBA), Zimmer Biomet Holdings, Inc. (NYSE: ZBH) and HCA Holdings, Inc.; (ii) realized losses in connection with our investment in Samson Resources (energy sector); (iii) realized losses on assets held at consolidated CLOs; and (iv) realized gains on debt held at consolidated CLOs. For the year ended December 31, 2016, net unrealized losses were driven primarily by (i) mark-to-market losses in our private equity portfolio held by KKR's balance sheet including unrealized losses in First Data Corporation; (ii) mark-to-market losses on assets in our consolidated special situations funds; (iii) mark-to-market losses on debt held through consolidated CMBS; and (iv) the reversal of unrealized gains on the partial sales of Walgreens Boots Alliance, Inc., Zimmer Biomet Holdings, Inc. and HCA Holdings, Inc., as well as the reversal of unrealized gains on debt realizations at our consolidated CLOs. Offsetting these unrealized losses were unrealized gains, the most significant of which were unrealized gains relating to (i) the reversal of unrealized losses in connection with our investment in Samson Resources, (ii) reversals of unrealized losses on asset realizations in our consolidated CLOs and (iii) mark-to-market gains on investments held through consolidated CMBS structures.

For a discussion of other factors that affected KKR's realized investment income, see "—Segment Analysis."

Dividend Income

During the year ended December 31, 2017, the most significant dividends received included $88.5 million from our consolidated special situations funds and $43.5 million from our consolidated real estate funds. During the year ended December 31, 2016, the most significant dividends received included $51.5 million from our consolidated special situations funds and dividends from US Foods Holding Corp. of $23.4 million, Sedgwick Claims Management Services, Inc. (financial services sector) of $12.7 million, and PRA Health Sciences, Inc. (NASDAQ: PRAH) of $4.1 million. Significant dividends from portfolio companies are generally not recurring quarterly dividends, and while they may occur in the future, their size and frequency are variable. For a discussion of other factors that affected KKR's dividend income, see "—Segment Results—Segment Revenues—Principal Activities Revenues—Realized Investment Income."

Interest Income

The increase in interest income during the year ended December 31, 2017 was primarily due to a higher level of interest earned related to (i) an increase in the amount of investments in our consolidated special situations funds and other leveraged credit funds, (ii) the impact of the consolidation of three additional CLOs subsequent to the year ended December 31, 2016, (iii) an increase in the amount of investments held by KREF compared to the prior period and (iv) an increase in the amount of investments held at our India debt financing company. These increases were partially offset by a decrease in interest income at KFN primarily due to a smaller portfolio generating recurring income as well as a decrease associated with the paydown of CLO 2007-01 in the second quarter of 2016. For a discussion of other factors that affected KKR's interest income, see "—Segment Results—Segment Revenues—Principal Activities Revenues—Realized Investment Income."

Interest Expense

The increase in interest expense during the year ended December 31, 2017 was primarily due to the impact of (i) the consolidation of three additional CLOs subsequent to the year ended December 31, 2016, (ii) increased borrowings at our India debt financing company, (iii) increased CMBS issuances by KREF and (iv) increased borrowings from asset backed financing vehicles managed by KKR. These increases were partially offset by a decrease in interest expense associated with certain notes issued by consolidated CLOs being called for redemption during the year ended December 31, 2016, which resulted in an increased level of interest expense during 2016. Specifically, as a result of a paydown made in August 2016, KKR recorded

increased interest expense of $59.9 million and an incremental $8.7 million of accelerated accretion of debt discounts during the year ended December 31, 2016. The paydown of CLO 2007-01 during the year ended December 31, 2016 also contributed to the increased interest expense in the prior period. For a discussion of other factors that affected KKR's interest expense, see "—Segment Analysis—Interest Expense."

Income (Loss) Before Taxes

The increase in income (loss) before taxes was due primarily to higher carried interest gains in our private equity portfolio and higher net gains from investment activities, partially offset by an increase in expenses, in each case as described above.

Income Taxes

The increase in income taxes is due primarily to accounting for the impacts of the 2017 Tax Act which was enacted on December 22, 2017. The 2017 Tax Act, among other provisions, reduced the U.S. federal corporate tax rate from 35% to 21%. Certain income tax effects of the 2017 Tax Act, including $97.9 million of tax expense recorded principally due to the remeasurement of our net deferred tax assets, are reflected in our financial results for the year ended December 31, 2017. This net write-down reduces our deferred tax assets and liabilities to a level that reflects the future tax benefit or liability that will be realized at the new U.S. federal corporate tax rate of 21%. For a discussion of factors that impacted KKR's tax provision, see Item 8. Financial Statements and Supplementary Data—Note 2 "Summary of Significant Accounting Policies" and Note 11 "Income Taxes."

Taxes also increased as a result of a higher level of fees earned by our management companies and capital markets companies during the year ended December 31, 2017 as compared to the prior period and to a lesser extent a higher level of carried interest gains accrued by certain general partner entities subject to corporate income tax.

Net Income (Loss) Attributable to Noncontrolling Interests

Net income attributable to noncontrolling interests for the year ended December 31, 2017 relates primarily to net income attributable to KKR Holdings representing its ownership interests in the KKR Group Partnerships as well as third-party limited partner interests in those investment funds that we consolidate. The increase from the prior period is due primarily to (i) higher amounts attributed to KKR Holdings in connection with higher income recognized for the year ended December 31, 2017 as compared to the prior period, partially offset by a reduction in KKR Holdings' ownership percentage in the KKR Group Partnerships and (ii) a higher level of income recorded by certain consolidated fund entities that is attributable to third-party limited partners.

Net Income (Loss) Attributable to KKR & Co. Inc.

The increase for the year ended December 31, 2017 was primarily due to increased fee income and to a lesser extent, higher carried interest gains and higher net investment gains from investment activities in the current period as compared to the prior period.

Consolidated Statements of Cash Flows

The accompanying consolidated statements of cash flows include the cash flows of our consolidated entities which include certain consolidated investment funds and CFEs notwithstanding the fact that we may hold only a minority economic interest in those funds and CFEs.

The assets of our consolidated funds and CFEs, on a gross basis, can be substantially larger than the assets of our business and, accordingly, could have a substantial effect on the cash flows reflected in our consolidated statements of cash flows. The primary cash flow activities of our consolidated funds and CFEs involve: (i) capital contributions from fund investors; (ii) using the capital of fund investors to make investments; (iii) financing certain investments with indebtedness; (iv) generating cash flows through the realization of investments; and (v) distributing cash flows from the realization of investments to fund investors. Because our consolidated funds and CFEs are treated as investment companies for accounting purposes, certain of these cash flow amounts are included in our cash flows from operations.

On January 1, 2018, KKR adopted ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which amends the guidance to add or clarify guidance on the classification and presentation of restricted cash in the statement of cash flows. Upon adoption, (i) Restricted Cash and Cash Equivalents and (ii) Cash and Cash Equivalents Held at Consolidated Entities were (a) included in the cash and cash-equivalents balances in the consolidated statements of cash flows and (b) disclosed in a reconciliation between the consolidated statements of financial condition and the consolidated statements of cash flows. This guidance has been applied on a full retrospective basis. For the years ended December 31, 2017 and 2016, $97.9 million and $121.0 million, respectively, of cash used by operating activities and $155.9 million and $1.4 million, respectively, of cash provided by investing activities were removed from net cash provided (used) by operating activities and net cash

provided (used) by investing activities, respectively, and included in net increase/(decrease) in cash, cash-equivalents and restricted cash in the consolidated statements of cash flows.

Net Cash Provided (Used) by Operating Activities

Our net cash provided (used) by operating activities was $(7.6) billion, $(3.5) billion and $(1.4) billion during the years ended December 31, 2018, 2017 and 2016, respectively. These amounts primarily included: (i) proceeds from investments net of investments purchased of $(8.5) billion, $(4.8) billion and $(1.2) billion during the years ended December 31, 2018, 2017 and 2016, respectively; (ii) net realized gains (losses) on investments of $534.7 million, $38.3 million and $347.1 million during the years ended December 31, 2018, 2017 and 2016, respectively; (iii) change in unrealized gains (losses) on investments of $720.2 million, $889.8 million and $(136.1) million during the years ended December 31, 2018, 2017 and 2016 respectively and (iv) capital allocation-based income of $554.5 million, $2,015.7 million and $935.1 million during the years ended December 31, 2018, 2017 and 2016, respectively. Investment funds are, for GAAP purposes, investment companies and reflect their investments and other financial instruments at fair value.

Net Cash Provided (Used) by Investing Activities

Our net cash provided (used) by investing activities was $(78.6) million, $(98.1) million and $(63.9) million during the years ended December 31, 2018, 2017 and 2016, respectively. Our investing activities included: (i) the purchase of fixed assets of $(102.7) million, $(97.1) million and $(62.7) million during the years ended December 31, 2018, 2017 and 2016, respectively; (ii) proceeds from sale of oil and natural gas properties of $26.6 million and $0.9 million for the years ended December 31, 2018 and 2016, respectively, and (iii) development of oil and natural gas properties of $(2.6) million, $(1.1) million and $(2.1) million for the years ended December 31, 2018, 2017, and 2016, respectively.

Net Cash Provided (Used) by Financing Activities

Our net cash provided (used) by financing activities was $6.6 billion, $2.9 billion and $3.1 billion during the years ended December 31, 2018, 2017 and 2016, respectively.

Fees and Other, Net

The increase for the year ended December 31, 2018 as compared to the year ended December 31, 2017 was primarily due to an increase in management fees and transaction fees, partially offset by a corresponding increase in fee credits.

The increase in management fees was primarily due to (i) management fees earned from our Asian Fund III which entered its investment period in the second quarter of 2017 (partial year of revenue in 2017), (ii) management fees earned from our Global Infrastructure Fund III which entered its investment period in the second quarter of 2018 and (iii) management fees earned from our Real Estate Partners Americas II fund which entered its investment period in the second quarter of 2017 (partial year of revenue in 2017). This net increase was partially offset by decreases due to (i) lower management fees calculated based on lower levels of invested capital as a result of realizations primarily in our European Fund III, 2006 Fund and Asian Fund, (ii) lower management fees paid by our Asian Fund II when it entered its post-investment period in the second quarter of 2017, in which it pays fees at a lower rate than during the investment period and based on capital invested at the time rather than total committed capital, and (iii) lower management fees earned from our Real Estate Partners Americas fund which entered its post-investment period in the second quarter of 2017, in which it pays fees based on capital invested rather than remaining commitments and capital invested during the investment period. For each of our Asian Fund II and Real Estate Partners Americas fund, the reduction in fees in 2017 was for a partial year, whereas 2018 experienced a full year of reduced fees.

The increase in transaction fees was primarily attributable to an increase in the size of transaction fee-generating investments. During the year ended December 31, 2018, there were 41 transaction fee-generating investments that paid an average fee of $7.4 million compared to 46 transaction fee-generating investments that paid an average fee of $6.3 million during the year ended December 31, 2017. For the year ended December 31, 2018, approximately 59% of these transaction fees were paid by companies located in North America, 22% were paid from companies located in the Asia-Pacific region and 19% were paid from companies in Europe. Transaction fees vary by investment based upon a number of factors, the most significant of which are transaction size, the particular agreements as to the amount of the fees, the complexity of the transaction and KKR's role in the transaction. Additionally, transaction fees are generally not earned with respect to energy and real estate investments. The increase in fee credits is due primarily to a higher level of transaction fees and monitoring fees reimbursable to the fund investors.

The increase in monitoring fees was primarily attributable to an increase in recurring monitoring fees compared to the prior period, partially offset by lower termination payments. Recurring monitoring fees increased $18.6 million, which was primarily the result of an increase in both the size and number of portfolio companies paying monitoring fees. For the year ended December 31, 2018, we had 71 portfolio companies that were paying an average monitoring fee of $1.1 million compared with 66 portfolio companies that were paying an average monitoring fee of $0.9 million for the year ended December 31, 2017. For the year ended December 31, 2018, we received termination payments of $7.5 million in connection with the IPO of BrightView Holdings, Inc. (NYSE: BV) compared to $19.6 million of termination payments received in the year ended December 31, 2017 relating to the IPO of Gardner Denver Holdings, Inc. (NYSE: GDI) and National Vision Holdings, Inc. (NASDAQ: EYE). These termination payments may occur in the future; however, they are infrequent in nature and are generally correlated with the IPO and other realization activity in our private equity portfolio, and are expected to continue to be smaller in size and number compared to prior periods.

Fees and Other, Net

The increase for the year ended December 31, 2018 was primarily due to an increase in management fees, partially offset by a decrease in transaction fees, net of fee credits. The increase in management fees was primarily due to (i) an increase in fees earned from BDCs advised by FS/KKR Advisor resulting in part from the completion of the FS Investments Transaction in the second quarter of 2018, (ii) increased fees from our hedge fund partnerships as a result of greater FPAUM, and (iii) an increase in fees in our Special Situations Fund II as a result of increased capital invested. As a result of the closing of the FS Investments Transaction on April 9, 2018, KKR began receiving its portion of the management and incentive fees on an additional $13.2 billion of FPAUM (relating to FS Investments' BDCs), which are reflected in our operating results beginning in the second quarter of 2018. These increases were partially offset by a reduction in management fees from Prisma as a result of the PAAMCO Prisma transaction that closed in the second quarter of 2017. KKR reports its investment in PAAMCO Prisma using the equity method of accounting, and on a segment basis, KKR reflects its allocation of the net income of PAAMCO Prisma as management fees and realized incentive fees. Accordingly, the management fees and other revenues and expenses of Prisma that had been reported on a gross basis prior to the closing of the transaction on June 1, 2017 are reflected on a net basis as part of our allocation of the net income of PAAMCO Prisma after June 1, 2017 resulting in a decrease in our reported gross management fees when compared to the prior period. The decrease in transaction fees was driven primarily by an $18.5 million breakup fee received in the year ended December 31, 2017 in connection with a terminated transaction and included in transaction fees, compared to no such breakup fees in the year ended December 31, 2018. The net amount of this fee attributable to us after credits to our fund limited partners was $4.6 million.

Realized Performance Income

The increase for the year ended December 31, 2018 compared to the prior period was primarily attributable to higher incentive fees received from BDCs advised or sub-advised by KKR driven in part by the completion of the FS Investments Transaction in the second quarter of 2018, and to a lesser extent, higher incentive fees earned in our hedge fund partnerships and realized carried interest earned in our special situations strategy.

Capital Markets Revenues

Year Ended
December 31, 2018December 31, 2017Change
($ in thousands)
Transaction Fees$631,052$439,998$191,054

Transaction fees increased due primarily to an increase in both the size and number of capital markets transactions for the year ended December 31, 2018, compared to the year ended December 31, 2017. Overall, we completed 204 capital markets transactions for the year ended December 31, 2018, of which 28 represented equity offerings and 176 represented debt offerings, as compared to 193 transactions for the year ended December 31, 2017, of which 26 represented equity offerings and 167 represented debt offerings. Our capital markets fees are generated in connection with our Private Markets and Public Markets business lines as well as from third-party companies. For the year ended December 31, 2018, approximately 18% of our transaction fees were earned from unaffiliated third parties as compared to approximately 23% for the year ended December 31, 2017. Our transaction fees are comprised of fees earned from North America, Europe and Asia-Pacific. For the year ended December 31, 2018, approximately 30% of our transaction fees were generated outside of North America as compared to approximately 49% for the year ended December 31, 2017. Our Capital Markets business line is dependent on the overall capital markets environment, which is influenced by equity prices, credit spreads and volatility. Our Capital Markets business line does not generate management or monitoring fees.

(1)Given the extraordinary nature of the Conversion, the reported segment financial results for the year ended December 31, 2018 exclude approximately $729.4 million of losses on certain investments which were realized in the second quarter in advance of the Conversion.

Realized Investment Income

The increase is primarily due to an increased level of net realized gains and an increase in interest income and dividends during the year ended December 31, 2018, compared to the prior period.

For the year ended December 31, 2018, net realized gains were comprised primarily of gains from the sale of Private Markets investments including the sales or partial sales of our investments in First Data Corporation, Next Issue Media LLC (technology sector), and National Vision Holdings, Inc., as well as the sale of our equity interest in Nephila and the sale of our alternative credit investment in Amedisys, Inc. (NASDAQ: AMED). Offsetting these realized gains were realized losses, the most significant of which was a realized loss on Preferred Proppants, LLC. Given the extraordinary nature of the Conversion, the reported segment financial results for the year ended December 31, 2018 exclude approximately $729.4 million of realized losses on certain investments, primarily credit and energy investments, which were realized in the second quarter of 2018 in advance of the Conversion.

For the year ended December 31, 2017, net realized gains were comprised of gains primarily from the sale of private equity investments including the sales or partial sales of HCA Holdings, Inc., Walgreens Boots Alliance, Inc., and Visma AS (technology sector), partially offset by losses on the sale of Fortune Creek Partnership and the restructurings of Algeco Scotsman (industrial sector) and Aurora Eaglebine.

For the year ended December 31, 2018, interest income and dividends were comprised of (i) $174.4 million of interest income which consists primarily of interest that is received from our Public Markets investments, including CLOs and other credit investments and, to a lesser extent, our Capital Markets business and our cash balances and (ii) $112.1 million of dividend income from distributions received primarily through our real assets investments, including our real estate investment in KREF and our energy investments, as well as our credit investments.

For the year ended December 31, 2017, interest income and dividends were comprised of (i) $163.4 million of interest income which consists primarily of interest that is received from our Public Markets investments, including CLOs and other credit investments and, to a lesser extent, our India debt financing company and our cash balances and (ii) $122.3 million of dividend income from distributions received primarily through our private equity investments and real estate investments, including our investment in KREF.

Subsequent to December 31, 2018, we completed, or expect to complete sales, partial sales or secondary sales with respect to certain private equity portfolio companies and other investments as well as other realization activities such as the receipt of dividends and interest income across our broader portfolio. The most significant of these transactions are Sedgwick Claims Management Services, Inc., United Group B.V. (telecom sector), and MMI Holdings Limited (technology sector). These realization activities, if and when completed, are expected to result in realized performance income and realized investment income of approximately $400 million. Some of these transactions are not complete, and are subject to the satisfaction of closing conditions; there can be no assurance if or when any of these transactions will be completed.

Segment Expenses

Compensation and Benefits

The increase for the year ended December 31, 2018 compared to the prior period was due primarily to higher compensation recorded in connection with higher total segment revenues and includes higher equity-based compensation charges resulting from an increase in the weighted average number of unvested shares outstanding.

Occupancy and Other Operating Expenses

The increase for the year ended December 31, 2018 compared to the prior period is primarily due to a higher level of expenses that are creditable to our investment funds, which includes broken-deal expenses, and a higher level of professional fees and other administrative costs in connection with the growth of the firm. The level of broken-deal expenses can vary significantly period to period based upon a number of factors, the most significant of which are the number of potential investments being pursued for our investment funds, the size and complexity of investments being pursued and the number of investment funds currently in their investment period.

Interest Expense

For the year ended December 31, 2018 and 2017 interest expense relates primarily to the senior notes outstanding for KKR and KFN. The increase in interest expense for the year ended December 31, 2018 compared to the prior period is due to overall higher levels of borrowings, in particular at our Capital Markets business line under a revolving credit agreement.

Income Taxes Paid

The increase in income taxes paid is primarily due to a higher level of income that is subject to corporate taxes following the Conversion. Prior to the Conversion, KKR's investment income and carried interest generally were not subject to U.S. corporate income taxes. Subsequent to the Conversion, all income earned by KKR is subject to U.S. corporate income taxes which we believe will result in an overall higher income taxes paid when compared to periods prior to the Conversion. As a result of the Conversion, KKR recognized a partial step-up in the tax basis of certain assets that will be recovered as those assets are sold or the basis is amortized. This generally results in a lower level of taxable gains upon realization of carried interest and investment income for those assets that existed on the date of the Conversion. Over time as these assets with higher tax basis are realized, we expect that our income taxes paid and segment effective tax rate will increase. The pace of such increase is not currently known and is dependent on a variety of factors including the pace at which the assets with higher tax basis are realized and the mix of all assets realized in any given period. Therefore, we cannot predict what the increase, if any, in income taxes paid will be quarter-over-quarter or year-over-year.

After-tax Distributable Earnings

The net increase in after-tax distributable earnings for the year ended December 31, 2018 compared to the prior period was due primarily to higher transaction fees, realized investment income, management fees and realized performance income, partially offset by a higher level of compensation expense and income taxes paid in the current period compared to the prior period.

Private Markets

The following table reflects the changes in our Private Markets AUM from December 31, 2017 to December 31, 2018:

($ in thousands)
December 31, 2017$97,527,100
New Capital Raised14,755,500
Distributions and Other(12,751,000)
Change in Value3,864,900
December 31, 2018$103,396,500

AUM for the Private Markets business line was $103.4 billion at December 31, 2018, an increase of $5.9 billion, compared to $97.5 billion at December 31, 2017.

The increase was primarily attributable to (i) new capital raised in our Global Infrastructure Investors III Fund and our European Fund V and (ii) to a lesser extent, an increase in the value of our Private Markets portfolio. These increases were partially offset by distributions to Private Markets fund investors primarily as a result of realizations, most notably in our North America Fund XI, 2006 Fund, and European Fund III.

The increase in the value of our Private Markets portfolio was driven primarily by net gains of $0.4 billion in each of our European Fund IV, European Fund III, 2006 Fund and Asian Fund III and $0.2 billion in each of our Global Infrastructure Investors II Fund, Americas Fund XII and Next Generation Technology Growth Fund.

For the year ended December 31, 2018, the value of our private equity investment portfolio increased 5.1%. This was comprised of a 12.3% increase in value of our privately held investments and a 7.9% decrease in the share prices of various publicly held or publicly indexed investments.

The most significant increases in value of our privately held investments for the year ended December 31, 2018 related to increases in Sedgwick Claims Management Services, Inc., Internet Brands, Inc. (technology sector), and Cognita Schools Ltd (education sector). These increases in value on our privately held investments were partially offset by decreases in value

relating primarily to Arbor Pharmaceuticals, Inc. (health care sector), Resource Environmental Solutions, LLC (energy sector), and Mandala Energy Ltd. (energy sector). The increased valuations of individual companies in our privately held investments, in the aggregate, generally related to (i) in the case of Sedgwick Claims Management Services, Inc. and Cognita Schools Ltd, a valuation that reflects an agreement to sell these investments, (ii) an increase in the value of market comparables, and (iii) individual company performance. The decreased valuations of individual companies in our privately held investments, in the aggregate, generally related to (i) individual company performance or, in certain cases, an unfavorable business outlook and (ii) a decrease in the value of market comparables.

The most significant decreases in share prices for the year ended December 31, 2018 of various publicly held or publicly indexed investments were losses in Gardner Denver Holdings, Inc., BrightView Holdings, Inc., and National Vision Holdings, Inc. These decreases were partially offset by increases in share prices of various publicly held investments, the most significant of which were gains in First Data Corporation, Go Daddy Inc., and PT Japfa Comfeed Indonesia Tbk. (IDX: JPFA).

For the year ended December 31, 2017, the value of our private equity investment portfolio increased 23.3%. This was comprised of a 34.6% increase in the share prices of various publicly held or publicly indexed investments and a 16.7% increase in value of our privately held investments. Additionally, our infrastructure investment portfolio, which is comprised predominately of private investments, increased 21.7%.

The most significant increases in share prices of various publicly held or publicly indexed investments were gains in Gardner Denver Holdings, Inc., National Vision Holdings, Inc., and Qingdao Haier Co., Ltd. (CH: 600690) These increases were partially offset by decreased share prices of various publicly held investments, the most significant of which were losses in Fujian Sunner Development Co. Ltd. (SZ: 002299), Laureate Education, Inc. (NASDAQ: LAUR), and Engility Holdings, Inc. (NYSE: EGL).

Our privately held investments contributed the remainder of the change in value, the most significant of which were gains relating to Internet Brands, Inc., Weld North Holdings LLC (education sector), and Aricent Group (technology sector). The unrealized gains on our privately held investments were partially offset by unrealized losses relating primarily to Academy Ltd. (retail sector), Toys R Us, Inc. (retail sector), and Santanol Pty Ltd (forestry sector). The increased valuations of individual companies in our privately held investments, in the aggregate, generally related to (i) in the case of Weld North Holdings LLC and Aricent Group, valuations that reflect agreements to sell all or a portion of these investments, (ii) an increase in the value of market comparables and (iii) individual company performance. The decreased valuations of individual companies in our privately held investments, in the aggregate, generally related to (i) individual company performance or, in certain cases, an unfavorable business outlook and (ii) a decrease in the value of market comparables.

Certain investments included in our AUM are denominated in currencies other than the U.S. dollar. Those investments expose our AUM to the risk that the value of the investments will be affected by changes in exchange rates between the currency in which the investments are denominated and the currency in which the investments are made. We generally seek to reduce these risks by employing hedging techniques in connection with certain investments, including using foreign currency options and foreign exchange forward contracts to reduce exposure to changes in exchange rates when a meaningful amount of capital has been invested in currencies other than the currencies in which the investments are denominated. We do not, however, hedge our currency exposure in all currencies or for all investments. See "Quantitative and Qualitative Disclosures about Market Risk—Exchange Rate Risk" and "Risk Factors—Risks Related to the Assets We Manage—We make investments in companies that are based outside of the United States, which may expose us to additional risks not typically associated with investing in companies that are based in the United States."

AUM in our Public Markets business line totaled $91.3 billion at December 31, 2018, an increase of $20.4 billion compared to AUM of $70.9 billion at December 31, 2017. The increases due to new capital raised were related to multiple strategies, most notably $7.8 billion in certain leveraged credit strategies, $5.7 billion in our hedge fund partnerships, $2.7 billion in CLOs, and $2.4 billion in our private credit strategies. The "Impact of Other Transactions" activity represents the net impact of (i) $13.2 billion relating to AUM previously managed by FS Investments in connection with the completion of the FS Investments Transaction, (ii) a $1.9 billion increase in our pro rata portion of AUM managed by Marshall Wace in connection with the acquisition of an additional 5% interest in this hedge fund partnership, and (iii) a $3.1 billion decrease of AUM in connection with the sale of our equity interest in Nephila. Partially offsetting these increases were redemptions and distributions from certain investment vehicles across multiple strategies, primarily with our hedge fund partnerships, certain leveraged credit strategies and our private credit strategies. Change in value was driven primarily by net decreases in value of our hedge fund partnerships and our BDCs.

FPAUM in our Private Markets business line was $66.8 billion at December 31, 2018, an increase of $5.1 billion, compared to $61.7 billion at December 31, 2017.

The increase was primarily attributable to new capital raised in our Global Infrastructure Investors III Fund and capital invested in our core investment vehicles. These increases were partially offset by (i) distributions primarily relating to realizations in our 2006 Fund, European Fund III, and North America Fund XI and (ii) net changes in the fee base of our Global Infrastructure Fund II and Energy Income and Growth Fund as a result of these funds entering their post-investment period. With respect to the Global Infrastructure Fund II, post-investment period fees are based on net asset value as compared to investment period fees, which are based on remaining commitments & net asset value. With respect to the Energy Income and Growth Fund, post-investment period fees are based on invested capital as compared to investment period fees, which are based on remaining commitments and invested capital.

FPAUM in our Public Markets business line was $74.2 billion at December 31, 2018, an increase of $18.4 billion compared to FPAUM of $55.8 billion at December 31, 2017. The increases due to new capital raised were related to multiple strategies, most notably $7.7 billion in certain leveraged credit strategies, $3.7 billion in our hedge fund partnerships, $3.1 billion in our private credit strategies and $2.7 billion in our CLOs. The "Impact of Other Transactions" activity represents (i) a $13.2 billion increase relating to FPAUM previously managed by FS Investments in connection with the completion of the FS

Investments Transaction, (ii) a $1.9 billion increase in our pro rata portion of FPAUM managed by Marshall Wace in connection with the acquisition of an additional 5% interest in this hedge fund partnership and (iii) a $3.1 billion decrease of FPAUM in connection with the sale of our equity interest in Nephila. Partially offsetting these increases were (i) redemptions and distributions from certain investment vehicles across multiple strategies, primarily with our hedge fund partnerships, our private credit strategies, and certain leveraged credit strategies and (ii) decreases in value relating primarily to our hedge fund partnerships and our BDCs.

Uncalled Commitments

Private Markets

As of December 31, 2018, our Private Markets business line had $48.2 billion of remaining uncalled capital commitments that could be called for investments in new transactions as compared to $47.4 billion as of December 31, 2017. The increase is due primarily to new capital raised in our Global Infrastructure Investors III Fund and European Fund V, partially offset by capital called from fund investors to make investments during the period.

Public Markets

As of December 31, 2018, our Public Markets business line had $9.8 billion of uncalled capital commitments that could be called for investments in new transactions as compared to $9.1 billion as of December 31, 2017. The increase is due to new capital raised primarily in our direct lending strategies, partially offset by capital called from fund investors to make investments during the period.

Capital Invested and Syndicated Capital

Private Markets Capital Invested

For the year ended December 31, 2018, Private Markets had $13.2 billion of capital invested as compared to $13.3 billion for the year ended December 31, 2017. The decrease was driven primarily by a $0.4 billion decrease in capital invested in our private equity platform (including core investments and growth equity), partially offset by a $0.3 billion increase in capital invested in our real assets platforms. Generally, the portfolio companies acquired through our private equity funds have higher transaction values and result in higher capital invested relative to transactions in our real assets funds. The number of large private equity investments made in any quarterly or year-to-date period is volatile and, consequently, a significant amount of capital invested in one period or a few periods may not be indicative of a similar level of capital deployment in future periods. During the year ended December 31, 2018, 64% of capital deployed in private equity, which includes core and growth equity investments, was in transactions in North America, 24% was in the Asia-Pacific region and 12% was in Europe. As of February 1, 2019, our Private Markets business line had announced transactions that were subject to closing conditions which aggregated approximately $3.9 billion. These transactions are generally subject to the satisfaction of closing conditions prior to their completion, and there can be no assurance if or when any of these transactions will be completed.

Public Markets Capital Invested

For the year ended December 31, 2018, Public Markets had $6.9 billion of capital invested as compared to $5.0 billion for the year ended December 31, 2017. The increase was primarily due to a higher level of net capital deployed in our direct lending and private opportunistic credit strategies.

Capital Markets Syndicated Capital

For the year ended December 31, 2018, Capital Markets syndicated $6.3 billion of capital as compared to $4.7 billion for the year ended December 31, 2017. The increase was primarily due to an increase in the size and number of syndication transactions in the year ended December 31, 2018 as compared to the year ended December 31, 2017. Overall, we completed 16 syndication transactions for the year ended December 31, 2018 as compared to 15 syndications for the year ended December 31, 2017. The size and frequency of syndication transactions depend in large part on market conditions and other factors that are unpredictable and outside our control, which may negatively impact the fees generated by our capital markets business from syndication transactions.

The net increase was primarily due to an increase in transaction fees, partially offset by a corresponding increase in fee credits, and an increase in management fees.

The increase in transaction fees was primarily attributable to an increase in both the number and size of transaction fee-generating investments. During the year ended December 31, 2017, there were 46 transaction fee-generating investments that paid an average fee of $6.3 million compared to 35 transaction fee-generating investments paying an average fee of $3.8 million during the year ended December 31, 2016. Approximately 44% of these transaction fees were paid by companies located in North America, 32% were paid from companies located in the Asia-Pacific region and 24% were paid from companies in Europe. Transaction fees vary by investment based upon a number of factors, the most significant of which are transaction size, the particular discussions as to the amount of the fees, the complexity of the transaction and KKR's role in the transaction. The increase in fee credits is due primarily to a higher level of transaction fees.

The increase in management fees was primarily due to (i) Americas Fund XII entering its investment period in the first quarter of 2017, in which it earns management fees on a larger pool of capital than its predecessor fund North America Fund XI, which entered its post-investment period, (ii) Asian Fund III entering its investment period in the second quarter of 2017, in which it earns management fees on a larger pool of capital than its predecessor fund Asian Fund II, which entered its post-investment period and (iii) new capital raised in our Health Care Strategic Growth Fund. This net increase was partially offset by decreases due to (i) North America Fund XI and Asian Fund II entering their post-investment periods during 2017, in which they earn fees at a lower rate and based on invested capital rather than committed capital, and (ii) lower invested capital as a result of realizations primarily in our 2006 Fund, China Growth Fund and Asian Fund.

Recurring monitoring fees increased $12.4 million, which was primarily the result of an increase in the number of portfolio companies paying monitoring fees. For the year ended December 31, 2017, we had 66 portfolio companies that were paying an average monitoring fee of $0.9 million compared with 53 portfolio companies that were paying an average monitoring fee of $0.9 million for the year ended December 31, 2016. For the year ended December 31, 2017, we also received termination payments of $19.6 million in connection with the initial public offerings of Gardner Denver Holdings, Inc. and National Vision Holdings, Inc. compared to $15.3 million of termination payments received in the year ended December 31, 2016 in connection with the initial public offering of US Foods Holding Corp. These termination payments may occur in the future; however, they

are infrequent in nature and are generally correlated with the initial public offering and other realization activity in our private equity portfolio, and are expected to continue to be smaller in size and number compared to prior periods.

Fees and Other, Net

The net increase for the year ended December 31, 2017 was primarily due to an increase in transaction fees, partially offset by a corresponding increase in fee credits and a decrease in management fees. The increase in transaction fees was driven primarily by an $18.5 million breakup fee received in the year ended December 31, 2017 in connection with a terminated transaction, compared to having received no such breakup fees in the year ended December 31, 2016. The net amount of this fee attributable to us after credits to our fund investors was $4.6 million. The decrease in management fees related primarily to a reduction in management fees from Prisma as a result of the PAAMCO Prisma transaction that closed in the second quarter of 2017. KKR reports its investment in PAAMCO Prisma using the equity method of accounting, and on a segment basis, KKR reflects its allocation of the net income of PAAMCO Prisma as management fees and realized incentive fees. Accordingly, the management fees and other revenues and expenses of Prisma that had been reported on a gross basis prior to the closing of the transaction on June 1, 2017 are reflected on a net basis as part of our allocation of the net income of PAAMCO Prisma after June 1, 2017 resulting in a decrease in our reported gross management fees when compared to the prior period. This decrease was partially offset by capital invested in our Special Situations Fund II, Lending Partners II Fund, and Lending Partners Europe Fund as well as an increase in management fees in certain separately managed accounts and with our hedge fund partnerships.

Realized Performance Income

The net increase for the year ended December 31, 2017 compared to the prior period was primarily attributable to higher incentive fees earned in our hedge fund partnerships, which were partially offset by lower incentive fees received from BDCs advised or sub-advised by KKR and a lower level of realized carried interest.

Capital Markets Revenues

The following table presents Transaction Fees in the Capital Markets business line for the years ended December 31, 2017 and 2016:

Year Ended
December 31, 2017December 31, 2016Change
($ in thousands)
Transaction Fees$439,998$181,517$258,481

Transaction fees increased due primarily to an increase in both the size and number of capital markets transactions for the year ended December 31, 2017, compared to the year ended December 31, 2016. Overall, we completed 193 capital markets transactions for the year ended December 31, 2017, of which 26 represented equity offerings and 167 represented debt offerings, as compared to 117 transactions for the year ended December 31, 2016, of which 11 represented equity offerings and 106 represented debt offerings. We earned fees in connection with underwriting, syndication and other capital markets services. While each of the capital markets transactions that we undertake in this segment is separately negotiated, our fee rates are generally higher with respect to underwriting or syndicating equity offerings than with respect to debt offerings, and the amount of fees that we collect for like transactions generally correlates with overall transaction sizes. Our capital markets fees are generated in connection with our Private Markets and Public Markets businesses as well as from third-party companies. For the year ended December 31, 2017, approximately 23% of our transaction fees were earned from unaffiliated third parties as compared to approximately 28% for the year ended December 31, 2016. Our transaction fees are comprised of fees earned from North America, Europe, and Asia-Pacific, including India. For the year ended December 31, 2017, approximately 49% of our transaction fees were generated outside of North America as compared to approximately 34% for the year ended December 31, 2016. Our capital markets business line is dependent on the overall capital markets environment, which is influenced by equity prices, credit spreads and volatility. Our capital markets business line does not generate management or monitoring fees.

Total Realized Investment Income (Loss)$479,716$694,420$(214,704)

Realized Investment Income

The decrease is primarily due to a lower level of net realized gains and, to a lesser extent, a decrease in interest income and dividends during the year ended December 31, 2017, compared to the prior period.

For the year ended December 31, 2017, net realized gains were comprised primarily of gains from the sale of Private Markets investments including the sales or partial sales of HCA Holdings, Inc., Walgreens Boots Alliance, Inc. and Visma AS, partially offset by losses on the sale of Fortune Creek Partnership and the restructurings of Algeco Scotsman and Aurora Eaglebine.

For the year ended December 31, 2016, net realized gains were primarily comprised of gains from the sale of private equity investments including the sales or partial sales of Walgreens Boots Alliance, Inc., HCA Holdings, Inc., and Zimmer Biomet Holdings, Inc., offset by our investment in Samson Resources of approximately $254 million, the loss from the redemption of limited partner interests in a fund managed by BlackGold Capital Management, as well as certain CLOs being called. As of December 31, 2016, KKR no longer holds any limited partner interests in BlackGold Capital Management, although we continue to own an interest in its management company and fund general partner.

For the year ended December 31, 2017, interest income and dividends were comprised of (i) $163.4 million of interest income which consists primarily of interest that is received from our Public Markets investments including CLOs and other credit investments and to a lesser extent our Capital Markets business and our cash balances and (ii) $122.3 million of dividend income from distributions received primarily through our private equity investments and real estate investments including our investment in KREF.

For the year ended December 31, 2016, interest income and dividends were comprised of (i) $186.7 million of interest income which consists primarily of interest that is received from our Public Markets investments including CLOs and other credit investments and to a lesser extent our cash balances and other assets and (ii) $136.2 million of dividend income from distributions received primarily through our private equity investments, real estate investments including our investment in KREF and Public Markets investments.

The decrease in interest income and dividends is due primarily to the impact of a lower amount of capital invested in CLOs as well as a lower level of dividends for the year ended December 31, 2017 compared to the prior period.

Segment Expenses

Compensation and Benefits

The increase for the year ended December 31, 2017 compared to the prior period was primarily due to higher compensation and benefits expenses recorded in connection with higher total segment revenues, as well as higher equity-based compensation charges resulting from an increase in the weighted average number of unvested shares outstanding.

Occupancy and Other Operating Expenses

The net increase for the year ended December 31, 2017 compared to the prior period was primarily due to higher professional fees and other administrative costs in connection with the growth of the firm, partially offset by a decrease in expenses that are creditable to our investment funds, which includes broken-deal expenses.

Interest Expense

For the year ended December 31, 2017 and 2016, interest expense relates primarily to the senior notes outstanding for KKR and KFN. The decrease in interest expense for the year ended December 31, 2017 compared to the prior period is due to the redemption of KFN's 8.375% senior notes due 2041 and other debt after the third quarter of 2016, a portion of which was replaced with the issuance of KFN's 5.200% senior notes due 2033, which bears a lower rate of interest.

After-tax Distributable Earnings

The net increase in after-tax distributable earnings for the year ended December 31, 2017 compared to the prior period was due primarily to higher transaction fees and management fees. These increases were partially offset primarily by a lower level of realized investment income and a higher level of compensation and benefits expense in the current period compared to the prior period.

Private Markets

The following table reflects the changes in our Private Markets AUM from December 31, 2016 to December 31, 2017:

New Capital Raised25,455,400
Distributions and Other(12,503,200)
Change in Value10,759,400
December 31, 2017$97,527,100

AUM for the Private Markets segment was $97.5 billion at December 31, 2017, an increase of $23.7 billion, compared to $73.8 billion at December 31, 2016.

The increase was primarily attributable to (i) new capital raised primarily in our Asian Fund III, our core investment vehicles, two new strategic investor partnerships, our Real Estate Partners Americas II fund and our Real Estate Credit Opportunity Partners fund and (ii) to a lesser extent, an increase in the value of our Private Markets portfolio.

These increases were partially offset by (i) distributions to Private Markets fund investors primarily as a result of realizations most notably in our 2006 Fund, European Fund III and North America Fund XI, and (ii) a decrease of $0.8 billion reflecting expired commitments that are no longer eligible to be called for investments. Our flagship private equity funds, such as our Asian Fund III which represents $9.0 billion of AUM at December 31, 2017, are raised only episodically toward the end of the investment period of their predecessor funds or when their predecessor funds' capital becomes largely invested or allocated for investment.

The increase in the value of our Private Markets portfolio was driven primarily by net gains of $4.3 billion in our North America Fund XI, $1.0 billion in each of our European Fund IV and European Fund III, $0.9 billion in our 2006 Fund and $0.8 billion in our Asian Fund II.

For the year ended December 31, 2017, the value of our private equity investment portfolio increased 23.3%. This was comprised of a 34.6% increase in the share prices of various publicly held or publicly indexed investments and a 16.7% increase in value of our privately held investments. Additionally, our infrastructure investment portfolio, which is comprised predominately of private investments, increased 21.7%.

The most significant increases in share prices of various publicly held or publicly indexed investments were gains in Gardner Denver Holdings, Inc., National Vision Holdings, Inc., and Qingdao Haier Co., Ltd. These increases were partially offset by decreased share prices of various publicly held investments, the most significant of which were losses in Fujian Sunner Development Co. Ltd., Laureate Education, Inc., and Engility Holdings, Inc.

Our privately held investments contributed the remainder of the change in value, the most significant of which were gains relating to Internet Brands, Inc., Weld North Holdings LLC, and Aricent Group. The unrealized gains on our privately held investments were partially offset by unrealized losses relating primarily to Academy Ltd., Toys R Us, Inc., and Santanol Pty Ltd (forestry sector). The increased valuations of individual companies in our privately held investments, in the aggregate, generally related to (i) in the case of Weld North and Aricent Group, valuations that reflect agreements to sell all or a portion of these investments, (ii) an increase in the value of market comparables, and (iii) individual company performance. The decreased valuations of individual companies in our privately held investments, in the aggregate, generally related to (i) individual company performance or, in certain cases, an unfavorable business outlook and (ii) a decrease in the value of market comparables.

For the year ended December 31, 2016, the value of our private equity investment portfolio increased 11.9%. This was comprised of a 3.9% increase in the share prices of various publicly held or publicly indexed investments and an 18.4% increase in value of our privately held investments. The most significant increases in share prices of various publicly held or publicly indexed investments were gains in US Foods Holding Corp., PRA Health Sciences Inc. and HCA Holdings, Inc. These increases were partially offset by decreased share prices of various publicly held investments, the most significant of which were losses in First Data Corporation, Walgreens Boots Alliance, Inc. and Qingdao Haier Co., Ltd. Our privately held investments contributed the remainder of the change in value, the most significant of which were gains relating to Panasonic Healthcare Co. Ltd (health care sector), Capsugel S.A. and Sedgwick Claims Management Services, Inc. The unrealized gains on our privately held investments were partially offset by unrealized losses relating primarily to Aricent Group, OEG Management Partners Limited (energy sector), and Academy Ltd. The increased valuations of individual companies in our privately held investments, in the aggregate, generally related to (i) in the case of Panasonic Healthcare Co. Ltd, Capsugel S.A., and Sedgwick Claims Management Services Inc., valuations that reflect agreements to sell all or a portion of these investments, (ii) an increase in the value of market comparables and (iii) individual company performance. The decreased valuations of individual companies in our privately held investments, in the aggregate, generally related to (i) individual company performance or, in certain cases, an unfavorable business outlook and (ii) a decrease in the value of market comparables.

Certain investments included in our AUM are denominated in currencies other than the U.S. dollar. Those investments expose our AUM to the risk that the value of the investments will be affected by changes in exchange rates between the currency in which the investments are denominated and the currency in which the investments are made. Our policy is generally to reduce these risks in certain cases by employing hedging techniques, including using foreign currency options and foreign exchange forward contracts to reduce exposure to changes in exchange rates when a meaningful amount of capital has been invested in currencies other than the currencies in which the investments are denominated. We do not, however, hedge our currency exposure in all currencies or for all investments. See "—Quantitative and Qualitative Disclosures about Market Risk—Exchange Rate Risk" and "Risk Factors—Risks Related to the Assets We Manage—We make investments in companies that are based outside of the United States, which may expose us to additional risks not typically associated with investing in companies that are based in the United States."

December 31, 2017$70,943,500

AUM in our Public Markets segment totaled $70.9 billion at December 31, 2017, an increase of $15.2 billion compared to AUM of $55.7 billion at December 31, 2016. The increase for the period was primarily due to new capital raised across multiple strategies most notably $3.5 billion in certain leveraged credit strategies, $2.9 billion with our hedge fund partnerships, $2.4 billion in our CLOs, $1.5 billion in our private opportunistic credit strategy, $1.4 billion in two new strategic investor partnerships and $0.8 billion in our Lending Partners III Fund. The "Impact of Other Transactions" represents the closing of the PAAMCO Prisma transaction. This resulted in a net increase of approximately $3.8 billion reflecting the excess of our pro rata portion of the AUM of PAAMCO Prisma over the historical AUM of Prisma. For the year ended December 31, 2017, new capital raised offset redemptions with our hedge fund partnerships. The "Acquisitions" activity represents the increase in our pro rata portion of the AUM of Marshall Wace in connection with the acquisition of an additional 5% interest in this hedge fund partnership. The increases due to change in value were driven primarily by our hedge fund partnerships, our domestic private credit strategies and our European CLOs and certain European leveraged credit strategies. Partially offsetting these increases were redemptions and distributions from certain investment vehicles across multiple strategies, primarily with our hedge fund partnerships, our private credit strategies and our CLOs.

FPAUM in our Private Markets segment was $61.7 billion at December 31, 2017, an increase of $9.5 billion, compared to $52.2 billion at December 31, 2016.

The increase was primarily attributable to new capital raised in our Asian Fund III and our Real Estate Partners Americas II fund and capital invested in our Asian Fund II and North America Fund XI. These increases were partially offset by (i) distributions and other activity primarily relating to realizations in our 2006 Fund and European Fund III and (ii) net changes in the fee base of our Asian Fund II as a result of it entering into its post-investment period, during which it earns fees at a lower rate based on invested capital rather than committed capital.

FPAUM in our Public Markets segment was $55.8 billion at December 31, 2017, an increase of $6.5 billion compared to FPAUM of $49.3 billion at December 31, 2016. The increase was primarily due to new capital raised across multiple strategies, most notably $2.9 billion with our hedge fund partnerships, $2.7 billion in certain leveraged credit strategies, $2.4 billion in our CLOs, $1.1 billion in our Special Situations Fund II and $1.2 billion in our direct lending strategies. New capital raised includes capital that was raised in previous periods but began earning fees upon deployment of capital. For the year ended December 31, 2017, new capital raised offset redemptions with our hedge fund partnerships. Change in value was driven primarily by $1.1 billion through our hedge fund partnerships, $0.7 billion in certain leveraged credit strategies and $0.6 billion in our European CLOs. Partially offsetting these increases were redemptions and distributions from certain investment vehicles across multiple strategies driven by $2.9 billion from our hedge fund partnerships, $3.2 billion from our private credit strategies and $1.3 billion from our CLOs. The "Impact of Other Transactions" represents the closing of the PAAMCO Prisma transaction. This resulted in a net decrease of approximately $1.6 billion reflecting the excess of our historical FPAUM of Prisma, over our pro rata portion of the FPAUM of PAAMCO Prisma. FPAUM excludes assets under advisement of PAAMCO Prisma. The "Acquisitions" activity represents the increase in our pro rata portion of the AUM of Marshall Wace in connection with the acquisition of an additional 5% interest in this hedge fund partnership.

Uncalled Commitments

Private Markets

As of December 31, 2017, our Private Markets segment had $47.4 billion of remaining uncalled capital commitments that could be called for investments in new transactions. The increase from December 31, 2016 is due primarily to new capital

raised in our Asian Fund III, our core investment vehicles, two new strategic investor partnerships and Real Estate Partners Americas II, partially offset by capital called from fund investors to fund investments during the period.

Public Markets

As of December 31, 2017, our Public Markets segment had $9.1 billion of uncalled capital commitments that could be called for investments in new transactions. The increase from December 31, 2016 is due to new capital raised primarily in our private opportunistic credit strategy, two new strategic investor partnerships and Lending Partners III Fund, partially offset by capital called from fund investors to fund investments during the period.

Capital Invested and Syndicated Capital

Private Markets Capital Invested

The increase was driven primarily by a $4.5 billion increase in capital invested in our private equity platform, which includes an increase in core equity investments of $1.0 billion consisting of an investment in USI, Inc. and a $2.5 billion increase in capital invested in our real assets and other platforms. Generally, the portfolio companies acquired through our private equity funds have higher transaction values and result in higher capital invested relative to transactions in our real assets funds. The number of large private equity investments made in any quarter is volatile and consequently, a significant amount of capital invested in one quarter or a few quarters may not be indicative of a similar level of capital deployment in future quarters. During the year ended December 31, 2017, 41% of capital deployed in private equity, which does not include core investments, was in transactions in North America, 37% was in the Asia-Pacific region and 22% was in Europe.

Public Markets Capital Invested

Capital invested increased for the year ended December 31, 2017, compared to the year ended December 31, 2016. The increase is primarily due to a higher level of net capital deployed in our direct lending and special situations strategies.

Capital Markets Syndicated Capital

The increase is primarily due to an increase in the size and number of syndication transactions in the year ended December 31, 2017 as compared to the year ended December 31, 2016. Overall, we completed 15 syndication transactions for the year ended December 31, 2017 as compared to eight syndications for the year ended December 31, 2016.

Reconciliations to GAAP Measures

For the reconciliations of the most directly comparable financial measures calculated and presented in accordance with GAAP to total segment revenues, total segment expenses, and after-tax distributable earnings, see Item 8. Financial Statements and Supplementary Data—Note 14 "Segment Reporting."

Segment Balance Sheet

Our segment balance sheet is the balance sheet of KKR & Co. Inc. and its subsidiaries on a segment basis which includes, but is not limited to, our investment management companies, broker-dealer companies, general partners of our investment funds, and KFN. Our segment balance sheet excludes the assets and liabilities of our investment funds and CFEs and other consolidated entities that are not subsidiaries of KKR & Co. Inc.

Investments

Investments is a term used solely for purposes of financial presentation of a portion of KKR's balance sheet and includes majority ownership of subsidiaries that operate KKR's asset management and other businesses, including the general partner interests of KKR's investment funds.

Cash and Short-Term Investments

Cash and short-term investments represent cash and liquid short-term investments in high-grade, short-duration cash management strategies used by KKR to generate additional yield on our excess liquidity and is used by management in evaluating KKR's liquidity position. We believe this measure is useful to stockholders as it provides additional insight into KKR's available liquidity. Cash and short-term investments differ from cash and cash equivalents on a GAAP basis as a result

of the inclusion of liquid short-term investments in cash and short-term investments. The impact that these liquid short-term investments have on cash and cash equivalents on a GAAP basis is reflected in the consolidated statements of cash flows within cash flows from operating activities. Accordingly, the exclusion of these investments from cash and cash equivalents on a GAAP basis has no impact on cash provided (used) by operating activities, investing activities or financing activities.

Book Value Per Outstanding Adjusted Share

Book value per outstanding adjusted share increased 9.6% from December 31, 2017. This increase was due primarily to a broad-based increase in the value of KKR's investment portfolio, including investments held directly by KKR as well as investments held through investment funds, such as KKR's private equity funds, where KKR is entitled to earn carried interest. For the year ended December 31, 2018, the value of KKR's balance sheet portfolio, on a segment basis, increased 7.1% and KKR's private equity portfolio increased 5.1%. The increase in KKR's balance sheet portfolio was primarily due to mark-to-market gains in our portfolio companies. For a further discussion, see "—Consolidated Results of Operations—Unrealized Gains from Investment Activities" and "—Consolidated Results of Operations—Unrealized Losses from Investment Activities." For a discussion of the changes in KKR's private equity portfolio, see "—Segment Analysis—Other Operating and Performance Measures—AUM." The increase in book value per outstanding adjusted share was also due to approximately $1.6 billion of after-tax distributable earnings which were partially offset by dividends to Class A common stockholders during the year ended December 31, 2018. Effective as of September 30, 2018, KKR's segment balance sheet reflects KKR's tax assets and liabilities as prepared under GAAP, which increased book value by approximately $160 million as of such date. For a discussion of factors that impacted KKR's after-tax distributable earnings, see "—Segment Analysis—Segment Results."

The following table presents the holdings of our segment balance sheet by asset class as of December 31, 2018. To the extent investments on our segment balance sheet are realized at values below their cost in future periods, after-tax distributable earnings would be adversely affected by the amount of such loss, if any, during the period in which the realization event occurs.

See Item 8. Financial Statements and Supplementary Data—Note 12 "Equity Based Compensation."

Liquidity

We manage our liquidity and capital requirements by focusing on our cash flows before the consolidation of our funds and CFEs and the effect of changes in short term assets and liabilities, which we anticipate will be settled for cash within one year. Our primary cash flow activities on a segment basis typically involve: (i) generating cash flow from operations; (ii) generating income from investment activities, by investing in investments that generate yield (namely interest and dividends), as well as the sale of investments and other assets; (iii) funding capital commitments that we have made to, and advancing capital to, our funds and CLOs; (iv) developing and funding new investment strategies, investment products, and other growth initiatives, including acquisitions of other investments, assets, and businesses; (v) underwriting and funding commitments in our capital markets business; (vi) distributing cash flow to our stockholders and holders of our Series A and Series B Preferred Stock; and (vii) paying borrowings, interest payments, and repayments under credit agreements, our senior notes, and other borrowing arrangements. See "—Liquidity—Liquidity Needs—Dividends."

Sources of Liquidity

Our primary sources of liquidity consist of amounts received from: (i) our operating activities, including the fees earned from our funds, portfolio companies, and capital markets transactions; (ii) realizations on carried interest from our investment funds; (iii) interest and dividends from investments that generate yield, including our investments in CLOs; (iv) realizations on and sales of investments and other assets, including the transfers of investments for fund formations; and (v) borrowings under our credit facilities, debt offerings, and other borrowing arrangements. In addition, we may generate cash proceeds from sales of our equity securities.

Many of our investment funds provide carried interest. With respect to our private equity funds, carried interest is distributed to the general partner of a private equity fund with a clawback provision only after all of the following are met: (i) a realization event has occurred (e.g., sale of a portfolio company, dividend, etc.); (ii) the vehicle has achieved positive overall investment returns since its inception, in excess of performance hurdles where applicable; and (iii) with respect to investments with a fair value below cost, cost has been returned to fund investors in an amount sufficient to reduce remaining cost to the investments' fair value. As of December 31, 2018, certain of our funds had met the first and second criteria, as described above,

but did not meet the third criteria. In these cases, carried interest accrues on the consolidated statement of operations, but will not be distributed in cash to us as the general partner of an investment fund upon a realization event. For a fund that has a fair value above cost, overall, but has one or more investments where fair value is below cost, the shortfall between cost and fair value for such investments is referred to as a "netting hole." When netting holes are present, realized gains on individual investments that would otherwise allow the general partner to receive carried interest distributions are instead used to return invested capital to our funds' limited partners in an amount equal to the netting hole. Once netting holes have been filled with either (a) return of capital equal to the netting hole for those investments where fair value is below cost or (b) increases in the fair value of those investments where fair value is below cost, then realized carried interest will be distributed to the general partner upon a realization event. A fund that is in a position to pay cash carry refers to a fund for which carried interest is expected to be paid to the general partner upon the next material realization event, which includes funds with no netting holes as well as funds with a netting hole that is sufficiently small in size such that the next material realization event would be expected to result in the payment of carried interest. Strategic investor partnerships with fund investors may require netting across the various funds in which they invest, which may reduce the carried interest we otherwise would have earned if such fund investors were to have invested in our funds without the existence of the strategic investor partnership. See "Risk Factors—Risks Related to Our Business—Strategic investor partnerships have longer investment periods and invest in multiple strategies, which may increase the possibility of a 'netting hole,' which will result in less carried interest for us, as well as clawback liabilities."

As of December 31, 2018, netting holes in excess of $50 million existed at one of our private equity funds, which was North America Fund XI, which had a netting hole of approximately $73 million. In accordance with the criteria set forth above, other funds currently have and may in the future develop netting holes, and netting holes for those and other funds may otherwise increase or decrease in the future.

We have access to funding under various credit facilities, other borrowing arrangements and other sources of liquidity that we have entered into with major financial institutions or which we receive from the capital markets. The following describes these sources of liquidity.

Revolving Credit Agreements, Senior Notes, KFN Debt Obligations & KFN Securities

For a discussion of KKR's debt obligations, including our revolving credit agreements, senior notes, KFN debt obligations, and KFN securities, see Item 8. Financial Statements and Supplementary Data—Note 10 "Debt Obligations."

Preferred Stock

For a discussion of KKR's equity, including our preferred stock, see Item 8. Financial Statements and Supplementary Data—Note 15 "Equity."

Liquidity Needs

We expect that our primary liquidity needs will consist of cash required to:

•continue to grow our business lines, including seeding new strategies, funding our capital commitments made to existing and future funds, co-investments and any net capital requirements of our capital markets companies and otherwise supporting investment vehicles which we sponsor;
•warehouse investments in portfolio companies or other investments for the benefit of one or more of our funds, vehicles, accounts or CLOs pending the contribution of committed capital by the investors in such vehicles, and advancing capital to them for operational or other needs;
•service debt obligations including the payment of obligations upon maturity or redemption, as well as any contingent liabilities that may give rise to future cash payments;
•fund cash operating expenses and contingencies, including litigation matters;
•payment of corporate income taxes following the Conversion;
•pay amounts that may become due under our tax receivable agreement with KKR Holdings;
•pay cash dividends in accordance with our dividend policy for our Class A common stock or the terms of our preferred stock;
•underwrite commitments, advance loan proceeds and fund syndication commitments within our capital markets business;
•make future purchase price payments in connection with our proprietary investments, such as our hedge fund partnership with Marshall Wace, to the extent not paid by newly issued Class A common stock;
•acquire other assets for our Principal Activities business line, including other businesses, investments and assets, some of which may be required to satisfy regulatory requirements for our capital markets business or risk retention requirements for CLOs (to the extent it continues to apply); and
•repurchase KKR's Class A common stock pursuant to the share repurchase program or other securities issued by KKR.

KKR & Co. Inc. Share Repurchase Program

On October 27, 2015, KKR announced the authorization of a program providing for the repurchase by KKR of up to $500 million in the aggregate of its outstanding shares of Class A common stock. On February 9, 2017, KKR announced the authorization for KKR to repurchase an incremental $250 million under this unit repurchase program. On May 3, 2018, KKR announced the increase of the available amount under its repurchase program to $500 million, which may be used for the repurchase of its Class A common stock and the retirement of equity awards issued pursuant to our Equity Incentive Plan (and any successor equity plan thereto). During the fourth quarter of 2018, KKR repurchased 4.2 million shares for approximately $93 million and retired 1.6 million equity awards for approximately $46 million. As of December 31, 2018, approximately $868 million has been spent since October 27, 2015, representing a total of 51.8 million shares, to either repurchase shares or retire equity awards. As of December 31, 2018, approximately $282 million is available under the repurchase program.

Under the current repurchase program, KKR is authorized to repurchase its Class A common stock from time to time in open market transactions, in privately negotiated transactions or otherwise. The timing, manner, price and amount of any Class A common stock repurchases will be determined by KKR in its discretion and will depend on a variety of factors, including legal requirements, price and economic and market conditions. KKR expects that the program, which has no expiration date, will be in effect until the maximum approved dollar amount has been used. The program does not require KKR to repurchase

any specific number of shares of Class A common stock, and the program may be suspended, extended, modified or discontinued at any time.

In addition to the purchases of Class A common stock as described above, the repurchase program will be used for the retirement (by cash settlement or the payment of tax withholding amounts upon net settlement) of equity awards issued pursuant to our Equity Incentive Plan (and any successor equity plan thereto) representing the right to receive Class A common stock. See Item 5. "Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities."

Capital Commitments

The agreements governing our active investment funds generally require the general partners of the funds to make minimum capital commitments to such funds, which usually range from 2% to 8% of a fund's total capital commitments at final closing; however, the size of our general partner commitment to certain funds pursuing newer strategies may exceed this range. The following table presents our uncalled commitments to our active investment funds as of December 31, 2018:

Other Commitments

In addition to the uncalled commitments to our investment funds as shown above, KKR has entered into contractual commitments with respect to (i) the purchase of investments and other assets primarily in our Principal Activities business line and (ii) underwriting transactions, debt financing, and syndications in our Capital Markets business line. As of December 31, 2018, these commitments amounted to $370.5 million and $663.7 million, respectively. Whether these amounts are actually funded, in whole or in part, depends on the contractual terms of such commitments, including the satisfaction or waiver of any conditions to closing or funding. The unfunded commitments shown for our Capital Markets business line are shown without reflecting arrangements that may reduce the actual amount of contractual commitments shown occurring after December 31, 2018. Our capital markets business has an arrangement with a third party, which reduces our risk when underwriting certain debt transactions, and thus our unfunded commitments as of December 31, 2018 are reduced to reflect the amount to be funded by such third party. In the case of purchases of investments or assets in our Principal Activities business line, the amount to be funded includes amounts that are intended to be syndicated to third parties, and the actual amounts to be funded may be less than shown.

Investment in Marshall Wace

In connection with our investment in Marshall Wace, either of Marshall Wace or KKR may, in the fourth quarter of 2019, exercise a put option or a call option, respectively, that would give KKR an incremental 5% equity interest in Marshall Wace. KKR currently holds an ownership interest of 34.6%. The exercise of such options would require the use of cash and/or KKR

Class A common stock. For further information on this and prior option exercises, see Item 8. Financial Statements and Supplementary Data—Note 4 "Investments—Equity Method."

Tax Receivable Agreement

We may be required to acquire KKR Group Partnership Units from time to time pursuant to our exchange agreement with KKR Holdings, which may result in an increase in our tax basis of the assets of the KKR Group Partnerships at the time of an exchange of KKR Group Partnership Units. We have entered into a tax receivable agreement with KKR Holdings, which requires us to pay to KKR Holdings, or to current and former principals who have exchanged KKR Holdings units for KKR Class A common stock as transferees of KKR Group Partnership Units, 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax that we realize as a result of the increase in tax basis described above, as well as 85% of the amount of any such savings we realize as a result of increases in tax basis that arise due to future payments under the agreement. For the full description of the tax receivable agreement and our obligations thereunder, see Item 8. Financial Statements and Supplementary Data—Note 13 "Related Party Transactions—Tax Receivable Agreement," and for a discussion of amounts payable and cumulative cash payments made under the tax receivable agreement see "—Liquidity—Other Liquidity Needs—Contractual Obligations, Commitments and Contingencies."

Following the Conversion, we expect the amount of future payments under the tax receivable agreement to be materially higher than it would have been had we not converted to a corporation. In addition, our obligations under the tax receivable agreement would be effectively accelerated in the event of an early termination of the tax receivable agreement by us or in the event of certain mergers, asset sales and other forms of business combinations or other changes of control. See "Risk Factors—Risks Related to Our Organization—We will be required to pay our principals for most of the benefits relating to our use of tax attributes we receive from prior and future exchanges of our Class A common stock for KKR Group Partnership Units and related transactions."

Dividends

A dividend of $0.125 per share of Class A common stock has been declared, which will be paid on February 26, 2019 to holders of record of Class A common stock as of the close of business on February 11, 2019.

A dividend of $0.421875 per share of Series A Preferred Stock has been declared and set aside for payment on March 15, 2019 to holders of record of Series A Preferred Stock as of the close of business on March 1, 2019. A dividend of $0.406250 per share of Series B Preferred Stock has been declared and set aside for payment on March 15, 2019 to holders of record of Series B Preferred Stock as of the close of business on March 1, 2019.

When KKR & Co. Inc. receives distributions from the KKR Group Partnerships (the holding companies of the KKR business), KKR Holdings receives its pro rata share of such distributions from the KKR Group Partnerships.

The declaration and payment of dividends to our Class A common stockholders will be at the sole discretion of our board of directors, and our dividend policy may be changed at any time. As a corporation, we expect our dividends to our Class A common stockholders, if declared, to be lower than the distribution amounts we declared in prior periods as a limited partnership. Our distribution policy as a limited partnership had been to pay annual aggregate distributions to holders of our common units of $0.68 per common unit, and our dividend policy after the Conversion and beginning with respect to the third quarter of 2018 is to pay dividends to holders of our Class A common stock in an initial annual aggregate amount of $0.50 per share (or a quarterly dividend of $0.125 per share), in each case, subject to the discretion of our board of directors based on a number of factors, including KKR’s future financial performance and other considerations that the board deems relevant, and compliance with the terms of KKR & Co. Inc.'s certificate of incorporation and applicable law. For U.S. federal income tax purposes, any dividends we pay following July 1, 2018 (including dividends on our preferred stock) generally will be treated as qualified dividend income for U.S. individual stockholders to the extent paid out of our current or accumulated earnings and profits, as determined for U.S. federal income tax purposes. No income, gains, losses, deductions or credits of KKR will flow through to the stockholders for U.S. federal income tax purposes following July 1, 2018. There can be no assurance that future dividends will be made as intended or at all or that any particular dividend policy for our Class A common stock will be maintained. Furthermore, the declaration and payment of distributions by the KKR Group Partnerships and our other subsidiaries may also be subject to legal, contractual and regulatory restrictions, including restrictions contained in our debt agreements and the terms of the preferred stock of the KKR Group Partnerships.

Other Liquidity Needs

We may also be required to fund various underwriting, syndication and fronting commitments in our capital markets business in connection with the underwriting of loans, securities or other financial instruments, which has increased in significance in recent periods and may continue to be significant in future periods. We generally expect that these commitments will be syndicated to third parties or otherwise fulfilled or terminated, although we may in some instances elect to retain a portion of the commitments for our own investment.

Contractual Obligations, Commitments and Contingencies

In the ordinary course of business, we and our consolidated funds and CFEs enter into contractual arrangements that may require future cash payments. The following table sets forth information relating to anticipated future cash payments as of December 31, 2018 excluding consolidated funds and CFEs with a reconciliation of such amounts to the anticipated future cash payments of KKR including consolidated funds and CFEs.

(1)These uncalled commitments represent amounts committed by us to fund a portion of the purchase price paid for each investment made by our investment funds which are actively investing. Because capital contributions are due on demand, the above commitments have been presented as falling due within one year. However, given the size of such commitments and the pace at which our investment funds make investments, we expect that the capital commitments presented above will be called over a period of several years. See "—Liquidity—Liquidity Needs."
(2)Amounts include: (i) $500 million aggregate principal amount of 6.375% Senior Notes due 2020 issued by KKR Group Finance Co. LLC, $500 million aggregate principal amount of 5.500% Senior Notes due 2043 issued by KKR Group Finance Co. II LLC and $1,000 million aggregate principal amount of 5.125% Senior Notes due 2044 issued by KKR Group Finance Co. III LLC, gross of unamortized discount; (ii) $367.8 million aggregate principal amount of 0.509% Senior Notes due 2023, 0.764% Senior Notes due 2025 and 1.595% Senior Notes due 2038 issued by KKR Group Finance Co. IV LLC (denominated in Japanese Yen); (iii) $500 million aggregate principal amount of KFN 2032 Senior Notes, gross of unamortized discount; (iv) $120 million aggregate principal amount of KFN 2033 Senior Notes; (v) $70.0 million aggregate principal amount of KFN 5.400% Senior Notes due 2033 and (vi) $258.5 million aggregate principal amount of KFN junior subordinated notes, gross of unamortized discount. KFN's debt obligations are non-recourse to KKR beyond the assets of KFN.
(3)These interest obligations on debt represent estimated interest to be paid over the maturity of the related debt obligation, which has been calculated assuming the debt outstanding at December 31, 2018 is not repaid until its maturity. Future interest rates are assumed to be those in effect as of December 31, 2018, including both variable and fixed rates, as applicable, provided for by the relevant debt agreements. The amounts presented above include accrued interest on outstanding indebtedness.
(4)Represents various commitments in our capital markets business in connection with the underwriting of loans, securities and other financial instruments. These commitments are shown net of amounts syndicated.
(5)Represents obligations in our capital markets business to lend under various revolving credit facilities.
(6)Represents commitments of KKR and KFN to fund the purchase of various investments.
(7)Represents the amount payable in 2019 upon delivery of a new KKR office being constructed, all or a portion of which represents construction financing obtained by the developer and may be refinanced upon delivery of the completed office.
(8)Represents uncalled commitments of our consolidated funds excluding KKR's portion of uncalled commitments as the general partner of the respective funds. Because capital contributions are due on demand, the above commitments have been presented as falling due within one year. However, given the size of such commitments and the pace at which our investment funds make investments, we expect that the capital commitments presented above will be called over a period of several years. See "—Liquidity—Liquidity Needs."
(9)Amounts include (i) financing arrangements entered into by our consolidated funds with the objective of providing liquidity to the funds of $4.2 billion, (ii) debt securities issued by our consolidated CLOs of $12.5 billion, (iii) debt securities issued by our consolidated CMBS entities of $1.9 billion and (iv) borrowings collateralized by specific investments and other assets held directly by majority-owned investment vehicles of $0.7 billion. In April 2018, a consolidated entity of KKR sold its controlling beneficial interest in four consolidated CMBS vehicles. Debt securities issued by consolidated CLOs and CMBS entities are supported solely by the investments held at the CLO and CMBS vehicles and are not collateralized by assets of any other KKR entity. Obligations under financing arrangements entered into by our consolidated funds are generally limited to our pro rata equity interest in such funds. Our management companies bear no obligations to repay any financing arrangements at our consolidated funds.
(10)The interest obligations on debt of our CFEs and other borrowings represent estimated interest to be paid over the maturity of the related debt obligation, which has been calculated assuming the debt outstanding at December 31, 2018 is not repaid until its maturity. Future interest rates are assumed to be those in effect as of December 31, 2018, including both variable and fixed rates, as applicable, provided for by the relevant debt agreements. The amounts presented above include accrued interest on outstanding indebtedness.
(11)Represents commitments of consolidated funds to fund the purchase of various investments.

The commitment table above excludes contractual amounts owed under the tax receivable agreement because the ultimate amount and timing of the amounts due are not presently known. As of December 31, 2018, an undiscounted payable of $117.9 million has been recorded in due to affiliates in the consolidated financial statements representing management's best estimate of the amounts currently expected to be owed under the tax receivable agreement. As of December 31, 2018, approximately $24.0 million of cumulative cash payments have been made under the tax receivable agreement. See "—Liquidity Needs—Tax Receivable Agreement" and "Part II. Item 1A. Risk Factors—We will be required to pay our principals for most of the benefits relating to our use of tax attributes we receive from prior and future exchanges of our Class A common stock for KKR Group Partnership Units and related transactions."

We may incur contingent liabilities for claims that may be made against us in the future. We enter into contracts that contain a variety of representations, warranties and covenants, including indemnifications. For example, certain of our investment funds and KFN have provided certain indemnities relating to environmental and other matters and have provided nonrecourse carve-out guarantees for fraud, willful misconduct and other customary wrongful acts, each in connection with the financing of certain real estate investments that we have made. KKR has also provided certain guarantees for fraud, willful misconduct, bankruptcy and other customary wrongful acts in connection with certain investment vehicles. KKR has also guaranteed certain of our employees' (other than our named executive officers) and consultants' personal loans obtained in connection with certain fund investments. We have also indemnified employees and non-employees against potential liabilities, in connection with their service as described under "Item 13. Certain Relationships and Related Transactions, and Director Independence-Indemnification of Directors, Officers and Others." In addition, we have also provided credit support to certain of our subsidiaries' obligations in connection with certain investment vehicles or partnerships that we manage. For example, KKR has guaranteed the obligations of a general partner to post collateral on behalf of its investment vehicle in connection with such vehicle's derivative transactions, and we have also agreed to be liable for certain investment losses and/or for providing liquidity in the events specified in the governing documents of certain investment vehicles. Our maximum exposure under these arrangements is currently unknown as our liabilities for these matters would require a claim to be made against us in the future.

The partnership documents governing our carry-paying funds generally include a "clawback" provision that, if triggered, may give rise to a contingent obligation requiring the general partner to return amounts to the fund for distribution to the fund investors at the end of the life of the fund. See Item 8. Financial Statements and Supplementary Data—Note 16 "Commitments and Contingencies—Contingent Repayment Guarantees" for further information on KKR's potential clawback obligations.

Off Balance Sheet Arrangements

Other than contractual commitments and other legal contingencies incurred in the normal course of our business, we do not have any off-balance sheet financings or liabilities.

Critical Accounting Policies

The preparation of our consolidated financial statements in accordance with GAAP requires our management to make estimates and judgments that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and reported amounts of fees, expenses and investment income. Our management bases these estimates and judgments on available information, historical experience and other assumptions that we believe are reasonable under the circumstances. However, these estimates, judgments and assumptions are often subjective and may be impacted negatively based on changing circumstances or changes in our analyses. If actual amounts are ultimately different from those estimated, judged or assumed, revisions are included in the consolidated financial statements in the period in which the actual amounts become known. We believe our critical accounting policies could potentially produce materially different results if we were to change underlying estimates, judgments or assumptions.

The following discusses certain aspects of our critical accounting policies. For a full discussion of these and all critical accounting policies, see Item 8. Financial Statements & Supplementary Data—Note 2 "Summary of Significant Accounting Policies."

Fair Value Measurements

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. Except for certain of KKR's equity method investments and debt obligations, KKR's investments and other financial instruments are recorded at fair value or at amounts whose carrying values approximate fair value.

GAAP establishes a hierarchical disclosure framework which prioritizes and ranks the level of market price observability used in measuring financial instruments at fair value. Investments and financial instruments measured and reported at fair value are classified and disclosed based on the observability of inputs used in the determination of fair values, as follows:

Level I

Pricing inputs are unadjusted, quoted prices in active markets for identical assets or liabilities as of the measurement date. The types of financial instruments included in this category are publicly-listed equities and securities sold short.

We classified 4.8% of total investments measured and reported at fair value as Level I at December 31, 2018.

Level II

Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the measurement date, and fair value is determined through the use of models or other valuation methodologies. The types of financial instruments included in this category are credit investments, investments and debt obligations of consolidated CLO entities, convertible debt securities indexed to publicly-listed securities, less liquid and restricted equity securities and certain over-the-counter derivatives such as foreign currency option and forward contracts.

We classified 39.3% of total investments measured and reported at fair value as Level II at December 31, 2018.

Level III

Pricing inputs are unobservable for the financial instruments and include situations where there is little, if any, market activity for the financial instrument. The inputs into the determination of fair value require significant management judgment or estimation. The types of financial instruments generally included in this category are private portfolio companies, real assets investments, credit investments, equity method investments for which the fair value option was elected and investments and debt obligations of consolidated CMBS entities.

We classified 55.9% of total investments measured and reported at fair value as Level III at December 31, 2018. The valuation of our Level III investments at December 31, 2018 represents management's best estimate of the amounts that we would anticipate realizing on the sale of these investments in an orderly transaction at such date.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety.

Level III Valuation Methodologies

With respect to our private equity portfolio, which includes growth equity investments, we generally employ two valuation methodologies when determining the fair value of an investment. The first methodology is typically a market comparables analysis that considers key financial inputs and recent public and private transactions and other available measures. The second methodology utilized is typically a discounted cash flow analysis, which incorporates significant assumptions and judgments. Estimates of key inputs used in this methodology include the weighted average cost of capital for the investment and assumed inputs used to calculate terminal values, such as exit EBITDA multiples. In certain cases the results of the discounted cash flow approach can be significantly impacted by these estimates. Other inputs are also used in both methodologies. Also, as discussed in greater detail under "—Business Environment" and "Risk Factors—Risks Related to the Assets We Manage—Our investments are impacted by various economic conditions that are difficult to quantify or predict, but may have a significant adverse impact on the value of our investments" in this report, a change in interest rates could have a significant impact on valuations. In addition, when a definitive agreement has been executed to sell an investment, KKR generally considers a significant determinant of fair value to be the consideration to be received by KKR pursuant to the executed definitive agreement.

Upon completion of the valuations conducted using these methodologies, a weighting is ascribed to each method, and an illiquidity discount is typically applied where appropriate. The ultimate fair value recorded for a particular investment will generally be within a range suggested by the two methodologies, except that the value may be higher or lower than such range in the case of investments being sold pursuant to an executed definitive agreement.

Across the total Level III private equity investment portfolio, including investments in both consolidated and unconsolidated investment funds, approximately 69% of the fair value is derived from investments that are valued based exactly 50% on market comparables and 50% on a discounted cash flow analysis. Less than 2% of the fair value of this Level III private equity investment portfolio is derived from investments that are valued either based 100% on market comparables or 100% on a discounted cash flow analysis. As of December 31, 2018, the overall weights ascribed to the market comparables methodology, the discounted cash flow methodology, and a methodology based on pending sales for this portfolio of Level III private equity investments were 41%, 47%, and 12%, respectively.

In the case of growth equity investments, enterprise values may be determined using the market comparables analysis and discounted cash flow analysis described above. A scenario analysis may also be conducted to subject the estimated enterprise values to a downside, base and upside case, which involves significant assumptions and judgments. A milestone analysis may also be conducted to assess the current level of progress towards value drivers that we have determined to be important, which involves significant assumptions and judgments. The enterprise value in each case may then be allocated across the investment's capital structure to reflect the terms of the security and subjected to probability weightings. In certain cases, the values of growth equity investments may be based on recent or expected financings.

Real asset investments in infrastructure, energy and real estate are valued using one or more of the discounted cash flow analysis, market comparables analysis and direct income capitalization, which in each case incorporates significant assumptions and judgments. Infrastructure investments are generally valued using the discounted cash flow analysis. Key inputs used in this methodology can include the weighted average cost of capital and assumed inputs used to calculate terminal values, such as exit EBITDA multiples. Energy investments are generally valued using a discounted cash flow analysis. Key inputs used in this methodology that require estimates include the weighted average cost of capital. In addition, the valuations of energy investments generally incorporate both commodity prices as quoted on indices and long-term commodity price forecasts, which may be substantially different from, and are currently higher than, commodity prices on certain indices for equivalent future dates. Certain energy investments do not include an illiquidity discount. Long-term commodity price forecasts are utilized to capture the value of the investments across a range of commodity prices within the energy investment portfolio associated with future development and to reflect a range of price expectations. Real estate investments are generally valued using a combination of direct income capitalization and discounted cash flow analysis. Key inputs used in such methodologies that require estimates include an unlevered discount rate and current capitalization rate, and certain real estate investments do not include a minimum illiquidity discount. The valuations of real assets investments also use other inputs.

On a segment basis, our energy real asset investments in oil and gas-producing properties as of December 31, 2018 had a fair value of approximately $668 million. Based on this fair value, we estimate that an immediate, hypothetical 10% decline in the fair value of these energy investments from one or more adverse movements to the investments' valuation inputs would result in a decline in book value of $66.8 million. As of December 31, 2018, if we were to value our energy investments using only the commodity prices as quoted on indices and did not use long-term commodity price forecasts, and also held all other inputs to their valuation constant, we estimate that book value would have been approximately $103 million lower.

These hypothetical declines relate only to book value. There would be no current impact on KKR's unrealized carried interest since all of the investment funds which hold these types of energy investments have investment values that are either below their cost or not currently accruing carried interest. Additionally, there would be no impact on fees since fees earned from investment funds which hold investments in oil and gas-producing properties are based on either committed capital or capital invested.

For GAAP purposes, where KKR holds energy investments consisting of working interests in oil and gas-producing properties directly and not through an investment fund, such working interests are consolidated based on the proportion of the working interests held by us. Accordingly, we reflect the assets, liabilities, revenues, expenses, investment income and cash flows of the consolidated working interests on a gross basis and changes in the value of these energy investments are not reflected as unrealized gains and losses in the consolidated statements of operations. Accordingly, a change in fair value for these investments does not result in a decrease in net gains (losses) from investment activities, but may result in an impairment charge reflected in general, administrative and other expenses. For segment purposes, these directly held working interests are treated as investments and changes in value are reflected in our segment results as unrealized gains and losses.

Credit Investments: Credit investments are valued using values obtained from dealers or market makers, and where these values are not available, credit investments are generally valued by us based on ranges of valuations determined by an independent valuation firm. Valuation models are based on discounted cash flow analyses, for which the key inputs are determined based on market comparables, which incorporate similar instruments from similar issuers.

Key unobservable inputs that have a significant impact on our Level III investment valuations as described above are included in Item 8. Financial Statements and Supplementary Data—Note 5 "Fair Value Measurements."

Level III Valuation Process

The valuation process involved for Level III measurements is completed on a quarterly basis and is designed to subject the valuation of Level III investments to an appropriate level of consistency, oversight, and review.

For Private Markets investments classified as Level III, investment professionals prepare preliminary valuations based on their evaluation of financial and operating data, company specific developments, market valuations of comparable companies and other factors. KKR begins its procedures to determine the fair values of its Level III assets one month prior to the end of a reporting period, and KKR follows additional procedures to ensure that its determinations of fair value for its Level III assets are appropriate as of the relevant reporting date. These preliminary valuations are reviewed by an independent valuation firm engaged by KKR to perform certain procedures in order to assess the reasonableness of KKR's valuations annually for all Level III investments in Private Markets and quarterly for investments other than certain investments, which have values less than preset value thresholds and which in the aggregate comprise less than 5% of the total value of KKR's Level III Private Markets investments. The valuations of certain real asset investments are determined solely by an independent valuation firm without the preparation of preliminary valuations by our investment professionals, and instead such independent valuation firm relies on valuation information available to it as a broker or valuation firm. For credit investments and debt obligations of consolidated CMBS vehicles, an independent valuation firm is generally engaged quarterly by KKR with respect to most investments classified as Level III. The valuation firm either provides a value or provides a valuation range from which KKR's investment professionals select a point in the range to determine the preliminary valuation or performs certain procedures in order to assess the reasonableness and provide positive assurance of KKR's valuations. After reflecting any input from the independent valuation firm, the valuation proposals are submitted for review and approval by KKR's valuation committees. As of December 31, 2018, less than 4% of the total value of our Level III credit investments were not valued with the engagement of an independent valuation firm.

KKR has a global valuation committee that is responsible for coordinating and implementing the firm's valuation process to ensure consistency in the application of valuation principles across portfolio investments and between periods. The global valuation committee is assisted by the asset class-specific valuation committees that exist for private equity (including core investments), growth equity, real estate, energy and infrastructure and credit. The asset class-specific valuation committees are responsible for the review and approval of all preliminary Level III valuations in their respective asset classes on a quarterly basis. The members of these valuation committees are comprised of investment professionals, including the heads of each respective strategy, and professionals from business operations functions such as legal, compliance and finance, who are not primarily responsible for the management of the investments. For periods prior to the completion of the PAAMCO Prisma transaction, when Level III valuations were required to be performed on hedge fund investments, a valuation committee for hedge funds reviewed these valuations.

All Level III valuations are also subject to approval by the global valuation committee, which is comprised of senior employees including investment professionals and professionals from business operations functions, and includes one of KKR's Co-Presidents and Co-Chief Operating Officers and its Chief Financial Officer, General Counsel and Chief Compliance Officer. When valuations are approved by the global valuation committee after reflecting any input from it, the valuations of Level III investments, as well as the valuations of Level I and Level II investments, are presented to the audit committee of the board of directors of KKR & Co. Inc. and are then reported to the board of directors.

As of December 31, 2018, upon completion by, where applicable, an independent valuation firm of certain limited procedures requested to be performed by them on certain investments, the independent valuation firm concluded that the fair values, as determined by KKR, of those investments reviewed by them were reasonable. The limited procedures did not involve an audit, review, compilation or any other form of examination or attestation under generally accepted auditing standards and were not conducted on all Level III investments. We are responsible for determining the fair value of investments in good faith, and the limited procedures performed by an independent valuation firm are supplementary to the inquiries and procedures that we are required to undertake to determine the fair value of the commensurate investments.

As described above, Level II and Level III investments were valued using internal models with significant unobservable inputs and our determinations of the fair values of these investments may differ materially from the values that would have resulted if readily observable inputs had existed. Additional external factors may cause those values, and the values of investments for which readily observable inputs exist, to increase or decrease over time, which may create volatility in our earnings and the amounts of assets and stockholders' equity that we report from time to time.

Changes in the fair value of investments impacts the amount of carried interest that is recognized as well as the amount of investment income that is recognized for investments held directly and through our consolidated funds as described below. We estimate that an immediate 10% decrease in the fair value of investments held directly and through consolidated investment funds generally would result in a commensurate change in the amount of net gains (losses) from investment activities for investments held directly and through investment funds and a more significant impact to the amount of carried interest recognized, regardless of whether the investment was valued using observable market prices or management estimates with significant unobservable pricing inputs. With respect to consolidated investment funds, the impact that the consequential decrease in investment income would have on net income attributable to KKR would generally be significantly less than the amount described above, given that a majority of the change in fair value of our consolidated funds would be attributable to noncontrolling interests and therefore we are only impacted to the extent of our carried interest and our balance sheet investments.

As of December 31, 2018, there were no investments which represented greater than 5% of total investments on a GAAP basis. On a segment basis, as of December 31, 2018, investments which represented greater than 5% of total segment investments consisted of First Data Corporation and USI, Inc. valued at $998.1 million and $650.1 million, respectively. Our investment income on a GAAP basis and our book value can be impacted by volatility in the public markets related to our holdings of publicly traded securities, including our sizable holdings of First Data Corporation. See "—Business Environment" for a discussion on the impact of global equity markets on our financial condition and "—Segment Balance Sheet" for additional information regarding our largest holdings on a segment basis.

Recognition of Investment Income

Investment income consists primarily of the net impact of: (i) realized and unrealized gains and losses on investments; (ii) dividends; (iii) interest income; (iv) interest expense and (v) foreign exchange gains and losses relating to mark-to-market activity on foreign exchange forward contracts, foreign currency options, foreign denominated debt and debt securities issued by consolidated CFEs.

Certain of our investment funds are consolidated. When a fund is consolidated, the portion of our funds' investment income that is allocable to our carried interests and capital investments is not shown in the consolidated financial statements. For funds that are consolidated, all investment income (loss), including the portion of a funds' investment income (loss) that is allocable to KKR's carried interest, is included in investment income (loss) on the consolidated statements of operations. The carried interest that KKR retains in net income (loss) attributable to KKR & Co. Inc. is reflected as an adjustment to net income (loss) attributable to noncontrolling interests. However, because certain of our funds remain consolidated and because we hold a minority economic interest in these funds' investments, our share of the investment income is less than the total amount of investment income presented in the consolidated financial statements for these consolidated funds.

Recognition of Carried Interest in the Statement of Operations

Carried interest entitles the general partner of a fund to a greater allocable share of the fund's earnings from investments relative to the capital contributed by the general partner and correspondingly reduces noncontrolling interests' attributable share of those earnings. Carried interest is earned by the general partner of those funds to the extent that cumulative investment returns are positive and where applicable, preferred return thresholds have been met. If these investment returns decrease or turn negative in subsequent periods, recognized carried interest will be reversed and reflected as losses in the statement of operations. For funds that are not consolidated, amounts earned pursuant to carried interest are included in capital allocation-based income in the consolidated statements of operations. Amounts earned pursuant to carried interest at consolidated funds are eliminated from fees and other upon consolidation of the fund and are included as investment income (loss) in net gains (losses) from investment activities along with all of the other investment gains and losses at the consolidated fund.

Carried interest is recognized in the statement of operations based on the contractual conditions set forth in the agreements governing the fund as if the fund were terminated and liquidated at the reporting date and the fund's investments were realized at the then estimated fair values. Due to the extended durations of our private equity funds, we believe that this approach results in income recognition that best reflects our periodic performance in the management of those funds. Amounts earned pursuant to carried interest are earned by the general partner of those funds to the extent that cumulative investment returns are positive and where applicable, preferred return thresholds have been met. If these investment amounts earned decrease or turn negative in subsequent periods, recognized carried interest will be reversed and to the extent that the aggregate amount of carry distributions received by the general partner during the term of the fund exceed the amount to which the general partner was ultimately entitled, a clawback obligation would be recorded. For funds that are not consolidated, this clawback obligation, if any, is reflected as a reduction of our investment balance as this is where carried interest is initially recorded. For funds that are consolidated, this clawback obligation, if any, is reflected as an increase in noncontrolling interests in the consolidated statements of financial condition.

Prior to January 1, 2016, most of our historical private equity funds that provide for carried interest do not have a preferred return. For these funds, the management company is required to refund up to 20% of any management fees earned from its limited partners in the event that the fund recognizes carried interest. At such time as the fund recognizes carried interest in an amount sufficient to cover 20% of the management fees earned or a portion thereof, a liability due to the fund's limited partners is recorded and revenue is reduced for the amount of the carried interest recognized, not to exceed 20% of the management fees earned. The refunds to the limited partners are paid, and liabilities relieved, at such time that the underlying investment is sold and the associated carried interest is realized. In the event that a fund's carried interest is not sufficient to cover all or a portion of the amount that represents 20% of the earned management fees, such management fees would be retained and not returned to the funds' limited partners.

Most of our newer investment funds that provide for carried interest, however, have a preferred return. In this case, the management company does not refund the management fees earned from the limited partners of the fund as described above. Instead, the management fee is effectively returned to the limited partners through a reduction of the realized gain on which carried interest is calculated. To calculate the carried interest, KKR calculates whether a preferred return has been achieved based on an amount that includes all of the management fees paid by the limited partners as well as the other capital contributions and expenses paid by them to date. To the extent the fund has exceeded the preferred return at the time of a realization event, and subject to any other conditions for the payment of carried interest like netting holes, carried interest is distributed to the general partner. Until the preferred return is achieved, no carried interest is recorded. Thereafter, the general partner is entitled to a catch up allocation such that the general partner's carried interest is paid in respect of all of the fund's net gains, including the net gains used to pay the preferred return, until the general partner has received the full percentage amount of carried interest that the general partner is entitled to under the terms of the fund. In general, investment funds that entitle the management company to receive an incentive fee have a preferred return and are calculated on a similar basis that takes into account management fees paid.
