Interest rate sensitivity

The tables below provide information about our financial instruments that are sensitive to changes in interest rates. The table below presents principal repayments and current weighted average interest rates on our debt obligations as of December 31, 2016. The variable rates presented reflect the weighted average LIBOR rates in effect for all debt tranches plus interest rate margins in effect as of December 31, 2016. The Term Loan A margin in effect at December 31, 2016 is 1.75%, and along with the revolving line of credit, is subject to adjustment depending upon changes in certain of our financial ratios, including a leverage ratio. Term Loan B currently bears interest at LIBOR plus an interest rate margin of 2.75%.

Our senior secured credit facilities, which include Term Loan A and Term Loan B, consist of various individual tranches of debt that can range in maturity from one month to twelve months (currently, all tranches are one month in duration). For Term Loan A and Term Loan B, each tranche bears interest at a LIBOR rate that is determined by the duration of such tranche plus an interest rate margin. The LIBOR variable component of the interest rate for each tranche is reset as such tranche matures and a new tranche is established. LIBOR can fluctuate significantly depending upon conditions in the credit and capital markets.

As of December 31, 2016, our Term Loan A bears interest at LIBOR plus an interest rate margin of 1.75% and our Term Loan B debt bears interest at LIBOR plus an interest rate margin of 2.75%. LIBOR was greater than the 0.75% embedded LIBOR floor on Term Loan B, resulting in Term Loan B being subject to LIBOR-based interest rate volatility on the LIBOR variable component of our interest rate as of December 31, 2016. The LIBOR based interest component is limited to a maximum LIBOR rate of 3.50% on the outstanding principal debt on Term Loan B and $87.5 million on Term Loan A as a result of the interest rate cap agreements, as described below.

As of December 31, 2016, we maintain several interest rate cap agreements that were entered into in November 2014 with notional amounts totaling $3.5 billion. These previously forward cap agreements became effective September 30, 2016 and have the economic effect of capping the LIBOR variable component of our interest rate at a maximum of 3.50% on an equivalent amount of our debt. These cap agreements expire on June 30, 2018. As of December 31, 2016, the total fair value of these cap agreements was an

asset of approximately $0.1 million. During the year ended December 31, 2016, we recognized debt expense of $2.0 million from these caps. During the year ended December 31, 2016, we recorded a loss of $1.2 million in other comprehensive income due to a decrease in the unrealized fair value of these cap agreements.

As of December 31, 2016, we maintain several forward interest rate cap agreements that were entered into in October 2015 with notional amounts totaling $3.5 billion. These forward cap agreements will become effective June 29, 2018 and will have the economic effect of capping the LIBOR variable component of our interest rate at a maximum of 3.50% on an equivalent amount of our debt. These cap agreements expire on June 30, 2020. As of December 31, 2016, the total fair value of these cap agreements was an asset of approximately $9.8 million. During the year ended December 31, 2016, we recorded a loss of $4.0 million in other comprehensive income due to a decrease in the unrealized fair value of these forward cap agreements.

Previously, we maintained several interest rate cap agreements with notional amounts totaling $2.7 billion on our Term Loan B debt. These agreements had the economic effect of capping the LIBOR variable component of our interest rate at a maximum of 2.50% on an equivalent amount of our Term Loan B. These interest rate cap agreements expired September 30, 2016. During the year ended December 31, 2016, we recognized debt expense of $1.8 million from these caps.

We also previously maintained several interest rate swap agreements. These agreements had the economic effect of modifying the LIBOR variable component of our interest rate on an equivalent amount of our Term Loan A to fixed rates ranging from 0.49% to 0.52%. These interest rate swap agreements required monthly interest payments and expired September 30, 2016. During the year ended December 31, 2016, we recognized debt expense of $0.3 million from these swaps and recorded a loss of $0.8 million in other comprehensive income due to a decrease in the unrealized fair value of these swap agreements.

Our overall weighted average effective interest rate on the senior secured credit facilities was 3.68%, based on the current margins in effect of 1.75% for Term Loan A and 2.75% for Term Loan B, as of December 31, 2016.

As of December 31, 2016, our Term Loan B debt bears interest at LIBOR plus an interest rate margin of 2.75%. Term Loan B is also subject to interest rate caps if LIBOR should rise above 3.50%. Term Loan A bears interest at LIBOR plus an interest rate margin of 1.75%. The capped portion of Term Loan A is $87.5 million. In addition, the uncapped portion of Term Loan A, which is subject to the variability of LIBOR, is $775 million. Interest rates on our senior notes are fixed by their terms.

Our overall weighted average effective interest rate during the year ended December 31, 2016 was 4.43% and as of December 31, 2016 was 4.52%.

As of December 31, 2016, we had undrawn revolving credit facilities totaling $1.0 billion of which approximately $95.2 million was committed for outstanding letters of credit. The remaining amount is unencumbered. In addition, DMG has an outstanding letter of credit of approximately $1.3 million which is secured by a certificate of deposit.

We believe that we will generate significant operating cash flows and will have sufficient liquidity to fund our scheduled debt service and other obligations and working capital needs for the foreseeable future, including the next 12 months, under the terms of our debt agreements. Our primary sources of liquidity are cash from operations and cash from borrowings.

One mean of assessing exposure to debt-related interest rate changes is a duration-based analysis that measures the potential loss in net income resulting from a hypothetical increase in interest rates of 100 basis points across all variable rate maturities (referred to as a parallel shift in the yield curve). Under this model, with all else constant, it is estimated that such an increase would have reduced net income by approximately $11.6 million, $9.3 million, and $5.7 million, net of tax, for the years ended December 31, 2016, 2015, and 2014, respectively.

Exchange rate sensitivity

While our business is predominantly conducted in the U.S. we have developing operations in 11 other countries as well. For financial reporting purposes, the U.S. dollar is our reporting currency. However, the functional currencies of our operating businesses in other countries are typically those of the countries in which they operate. Therefore, changes in the rate of exchange between the U.S. dollar and the local currencies in which our international operations are conducted affect our results of operations and financial position as reported in our consolidated financial statements.

We have consolidated the balance sheets of our non-U.S. dollar denominated operations into U.S. dollars at the exchange rates prevailing at the balance sheet date and have translated their revenues and expense at the average exchange rates for the period. Additionally, our individual subsidiaries are exposed to transactional risks mainly resulting from intercompany transactions between and among subsidiaries with different functional currencies. This exposes the subsidiaries to fluctuations in the rate of exchange between the invoicing or obligation currencies and the currency in which their local operations are conducted.

We evaluate our exposure to foreign exchange risk through the judgment of our regional and corporate management teams. Through 2016, our international operations remained small relative to the size of our consolidated financial statements, constituting less than 4% of our consolidated assets as of December 31, 2016 and approximately 1% of our consolidated net revenues for the year ended December 31, 2016. In addition, our foreign currency translation losses have remained less than approximately 2% of our consolidated operating income for the year ended December 31, 2016.

Given the still small size of our international operations, management does not consider our exposure to foreign exchange risk to be significant to the consolidated enterprise. As such, through December 31, 2016 we have not engaged in transactions to hedge the exposure of our international transactions or net investments to foreign currency risk. However, we may do so in the future.
