[removed: _The] [added: The] following discussion should be read in conjunction with the financial statements and notes thereto appearing elsewhere in this report.

Rewritten

For a discussion of such risk factors, see the section in this Form 10-K entitled “Risk Factors.” Amounts in thousands, except share and per share [removed: data._][added: data.]

Rewritten

[removed: Overview][added: Overview]

Rewritten

At December 31, [removed: 2015,] [added: 2016,] we owned, had ownership interests in, or managed [removed: 1,347] [added: 1,427] operating stores in [removed: 36] [added: 38] states, Washington, D.C. and Puerto Rico.

Rewritten

Of these [removed: 1,347] [added: 1,427] operating stores, we owned [removed: 746,] [added: 836,] we held joint venture interests in [removed: 253] [added: 180] stores, and our taxable REIT subsidiary, Extra Space Management, Inc., operated an additional [removed: 348] [added: 411] stores that are owned by third parties.

Rewritten

These operating stores contain approximately [removed: 101] [added: 107] million square feet of rentable space in approximately [removed: 896,000] [added: 960,000] units and currently serve a customer base of approximately [removed: 800,000] [added: 850,000] tenants.

Rewritten

[removed: A] [added: We consider a] store [removed: is considered] to be stabilized once it has achieved [added: either] an 80% occupancy rate for a full year measured as of January [removed: 1,] [added: 1 of the current year,] or has been open for three [removed: years.][added: years prior to the January 1 of the current year.]

Rewritten

Our operating results depend materially on our ability to lease available self-storage units, to actively manage unit rental rates, and on the ability of our [removed: tenants to make required rental payments.]

Rewritten

| [removed: |] • | [removed: | _Maximize] [added: Maximize] the performance of our stores through strategic, efficient and proactive [removed: management._] [added: management.] We pursue revenue-generating and expense-minimizing opportunities in our operations. Our revenue management team seeks to maximize revenue by responding to changing market conditions through our advanced technology system’s ability to provide real-time, interactive rental rate and discount management. Our size allows us greater ability than the majority of our competitors to implement more effective online marketing programs, which we believe will attract more customers to our stores at a lower net cost. |

Rewritten

| [removed: |] • | [removed: | _Acquire stores._] [added: Acquire self-storage stores.] Our acquisitions team continues to pursue the acquisition of multi-store portfolios and single stores that we believe can provide stockholder value. We have established a reputation as a reliable, ethical buyer, which we believe enhances our ability to negotiate and close acquisitions. In addition, we believe our status as an UPREIT enables flexibility when structuring deals. We continue to [removed: see] [added: review] available [removed: acquisitions on which to bid] [added: acquisitions. As interest rates increase, our expectation is that capitalization rates will also increase] and [removed: are seeing increasing prices. However, we] [added: that prices will begin to decrease. We] remain a disciplined buyer and [removed: look for] [added: only execute] acquisitions that [added: we believe] will strengthen our portfolio and increase stockholder value. |

Rewritten

| [removed: |] • | [removed: | _Expand] [added: Expand] our management [removed: business._] [added: business.] Our management business enables us to generate increased revenues through management fees and expand our geographic footprint. We believe this expanded footprint enables us to reduce our operating costs through economies of scale. In addition, we see our management business as a future acquisition pipeline. We pursue strategic relationships with owners whose stores would enhance our portfolio in the event an opportunity arises to acquire such stores. |

Rewritten

[removed: CRITICAL] [added: CRITICAL] ACCOUNTING POLICIES AND [removed: ESTIMATES][added: ESTIMATES]

Rewritten

For each VIE created, we have performed a qualitative analysis, including considering which party, if any, has the power to direct the activities most significant to the economic performance of each VIE and whether that party has the [added: obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE.]

Rewritten

As of December 31, [removed: 2015,] [added: 2016,] we had no consolidated VIEs.

In connection with our acquisition of [added: operating] stores, the purchase price is allocated to the tangible and intangible assets and liabilities acquired based on their fair values, which are estimated using significant unobservable inputs.

Rewritten

Intangible lease rights include: (1) purchase price amounts allocated to leases on three stores that cannot be classified as ground or building leases; these rights are amortized to expense over the term of the leases; and (2) intangibles related to ground leases on [removed: six] [added: eight] stores where the ground leases were assumed by [removed: the Company] [added: us] at rates that were different than the current market rates for similar leases.

Rewritten

[removed: EVALUATION] [added: EVALUATION] OF ASSET [removed: IMPAIRMENT:] [added: IMPAIRMENT:] Long lived assets held for use are evaluated for impairment when events or circumstances indicate that there may be impairment.

Rewritten

[removed: INVESTMENTS] [added: INVESTMENTS] IN UNCONSOLIDATED REAL ESTATE [removed: VENTURES:] [added: VENTURES:] Our investments in real estate joint ventures where we have significant influence but not control, and joint ventures which are VIEs in which we are not the primary beneficiary, are recorded under the equity method of accounting on the accompanying consolidated financial statements.

Rewritten

[removed: DERIVATIVE] [added: DERIVATIVE] INSTRUMENTS AND HEDGING [removed: ACTIVITIES:] [added: ACTIVITIES:] The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation.

Rewritten

[removed: REVENUE] [added: REVENUE] AND EXPENSE [removed: RECOGNITION:] [added: RECOGNITION:] Rental revenues are recognized as earned based upon amounts that are currently due from tenants.

New in FY2016

Property rental revenue also increased by $42,171 during the year ended December 31, 2016 as a result of increases in rental rates to new and existing customers at our stabilized stores.

New in FY2016

Revenues at our lease-up stores increased by $3,439 for the year ended December 31, 2016 due primarily to increases in occupancy.

New in FY2016

The achieved rental rate to new tenants on wholly owned properties for the year ended December 31, 2016 increased an average of approximately 7.0% over the prior year.

New in FY2016

New in FY2016

Tenant Reinsurance—The increase in tenant reinsurance revenues was due primarily to the increase in stores operated.

New in FY2016

Included in the acquisitions completed in 2015 was the acquisition of SmartStop Self Storage Inc. ("SmartStop") on October 1, 2015.

RECENT ACCOUNTING PRONOUNCEMENTS

Dropped from FY2015

In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-08, “_Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity._” Under this guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations.

Dropped from FY2015

The guidance also requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation.

Dropped from FY2015

The Company adopted this guidance effective January 1, 2015.

Dropped from FY2015

We have not previously had discontinued operations and as such, this guidance did not have a significant impact on our consolidated financial statements.

Dropped from FY2015

In May 2014, the FASB issued ASU 2014-09, “_Revenue from Contracts with Customers,_” which amends the guidance for revenue recognition to replace numerous, industry-specific requirements and converges areas under this topic with those of the International Financial Reporting Standards.

Dropped from FY2015

ASU 2014-09 outlines a five-step process for customer contract revenue recognition that focuses on transfer of control, as opposed to transfer of risk and rewards.

Dropped from FY2015

The amendment also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenues and cash flows from contracts with customers.

Dropped from FY2015

ASU 2014-09 was originally effective for reporting periods beginning after December 15, 2016.

Dropped from FY2015

Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption.

Dropped from FY2015

In July 2015, the FASB approved a one-year deferral of the effective date of the standard.

Dropped from FY2015

The new standard will now become effective for annual and interim periods beginning after December 15, 2017 with early adoption on the original effective date permitted.

Dropped from FY2015

The Company has not yet selected a transition method.

Dropped from FY2015

Management is currently assessing the impact of the adoption of ASU 2014-09 on our consolidated financial statements.

Dropped from FY2015

In February 2015, the FASB issued ASU 2015-02, “_Consolidation (Topic 810): Amendments to the Consolidation Analysis.”_ This guidance is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period.

Dropped from FY2015

ASU 2015-02 amends the criteria for determining if

a service provider possesses a variable interest in a variable interest entity (“VIE”), and eliminates the presumption that a general partner should consolidate a limited partnership.

Dropped from FY2015

We do not expect the adoption of this standard to materially impact its consolidated financial statements.

Dropped from FY2015

In April 2015, the FASB issued ASU 2015-03, “_Interest—Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs,_” which requires debt issuance costs related to a recognized debt liability to be presented as a direct deduction from the carrying amount of that debt liability.

Dropped from FY2015

The new guidance only impacts financial statement presentation.

Dropped from FY2015

The guidance is effective in the first quarter of 2016 and allows for early adoption.

Dropped from FY2015

We adopted this guidance October 1, 2015 on a retrospective basis.

Dropped from FY2015

As a result $20,120 of unamortized debt issuance costs that had been included in the Other assets line on the consolidated balance sheets as of December 31, 2014 are now presented as direct deductions from the carrying amounts of the related debt liabilities.

Dropped from FY2015

In April 2015, the FASB issued ASU 2015-05, “_Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40)—Customers Accounting for Fees Paid in a Cloud Computing Arrangement,_” which provides guidance regarding the accounting for fees paid by a customer in cloud computing arrangements.

Dropped from FY2015

If a cloud computing arrangement includes a software license, the payment of fees should be accounted for in the same manner as the acquisition of other software licenses.

Dropped from FY2015

If there is no software license, the fees should be accounted for as a service contract.

Dropped from FY2015

The guidance is effective in fiscal years beginning after December 15, 2015 and early adoption is permitted.

Dropped from FY2015

An entity can elect to adopt the amendments either (1) prospectively to all arrangements entered into or materially modified after the effective date or (2) retrospectively.

Dropped from FY2015

We do not expect the adoption of this standard to materially impact our consolidated financial statements.

Dropped from FY2015

In August 2015, the FASB issued ASU 2015-15, _“Interest—Imputation of Interest (Subtopic 835-30) Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements,”_ which provides guidance regarding the classification of debt issuance costs associated with lines of credit.
