EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended March 31, 2017 of Life Storage, Inc. (the “Parent Company”) and Life Storage LP (the “Operating Partnership”). The Parent Company is a real estate investment trust, or REIT, that owns its assets and conducts its operations through the Operating Partnership, a Delaware limited partnership, and subsidiaries of the Operating Partnership. The Parent Company, the Operating Partnership and their consolidated subsidiaries are collectively referred to in this report as the “Company.” In addition, terms such as “we,” “us,” or “our” used in this report may refer to the Company, the Parent Company and/or the Operating Partnership.

Life Storage Holdings, Inc., a wholly-owned subsidiary of the Parent Company (“Holdings”), is the sole general partner of the Operating Partnership; the Parent Company is a limited partner of the Operating Partnership, and through its ownership of Holdings and its limited partnership interest, controls the operations of the Operating Partnership, holding a 99.5% ownership interest therein as of March 31, 2017. The remaining ownership interests in the Operating Partnership are held by certain former owners of assets acquired by the Operating Partnership. As the owner of the sole general partner of the Operating Partnership, the Parent Company has full and complete authority over the Operating Partnership’s day-to-day operations and management.

Management operates the Parent Company and the Operating Partnership as one enterprise. The management teams of the Parent Company and the Operating Partnership are identical.

There are few differences between the Parent Company and the Operating Partnership, which are reflected in the note disclosures in this report. The Company believes it is important to understand the differences between the Parent Company and the Operating Partnership in the context of how these entities operate as a consolidated enterprise. The Parent Company is a REIT, whose only material asset is its ownership of the partnership interests of the Operating Partnership. As a result, the Parent Company does not conduct business itself, other than acting as the owner of the sole general partner of the Operating Partnership, issuing public equity from time to time and guaranteeing the debt obligations of the Operating Partnership. The Operating Partnership holds substantially all the assets of the Company and, directly or indirectly, holds the ownership interests in the Company’s real estate ventures. The Operating Partnership conducts the operations of the Company’s business and is structured as a partnership with no publicly traded equity. Except for net proceeds from equity issuances by the Parent Company, which are contributed to the Operating Partnership in exchange for partnership units, the Operating Partnership generates the capital required by the Company’s business through the Operating Partnership’s operations, by the Operating Partnership’s direct or indirect incurrence of indebtedness or through the issuance of partnership units of the Operating Partnership.

The substantive difference between the Parent Company’s filings and the Operating Partnership’s filings is the fact that the Parent Company is a REIT with public equity, while the Operating Partnership is a partnership with no publicly traded equity. In the financial statements, this difference is primarily reflected in the equity (or capital for the Operating Partnership) section of

2

the consolidated balance sheets and in the Shareholders’ Equity and Partners’ Capital notes to the financial statements. Apart from the different equity treatment, the consolidated financial statements of the Parent Company and the Operating Partnership are nearly identical.

The Company believes that combining the quarterly reports on Form 10-Q of the Parent Company and the Operating Partnership into a single report will:

• facilitate a better understanding by the investors of the Parent Company and the Operating Partnership by enabling them to view the business as a whole in the same manner as management views and operates the business;

• remove duplicative disclosures and provide a more straightforward presentation in light of the fact that a substantial portion of the disclosure applies to both the Parent Company and the Operating Partnership; and

• create time and cost efficiencies through the preparation of one combined report instead of two separate reports.

In order to highlight the differences between the Parent Company and the Operating Partnership, the separate sections in this report for the Parent Company and the Operating Partnership specifically refer to the Parent Company and the Operating Partnership. In the sections that combine disclosures of the Parent Company and the Operating Partnership, this report refers to such disclosures as those of the Company. Although the Operating Partnership is generally the entity that directly or indirectly enters into contracts and real estate ventures and holds assets and debt, reference to the Company is appropriate because the business is one enterprise and the Parent Company operates the business through the Operating Partnership.

As the owner of the general partner with control of the Operating Partnership, the Parent Company consolidates the Operating Partnership for financial reporting purposes, and the Parent Company does not have significant assets other than its investment in the Operating Partnership. Therefore, the assets and liabilities of the Parent Company and the Operating Partnership are the same on their respective financial statements. The separate discussions of the Parent Company and the Operating Partnership in this report should be read in conjunction with each other to understand the results of the Company’s operations on a consolidated basis and how management operates the Company.

This report also includes separate Item 4 - Controls and Procedures sections, signature pages and Exhibit 31 and 32 certifications for each of the Parent Company and the Operating Partnership in order to establish that the Chief Executive Officer and the Chief Financial Officer of the Parent Company and the Chief Executive Officer and the Chief Financial Officer of the Operating Partnership have made the requisite certifications and that the Parent Company and the Operating Partnership are compliant with Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934, as amended and 18 U.S.C. §1350.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. BASIS OF PRESENTATION

The accompanying unaudited financial statements of Life Storage, Inc. (the “Parent Company”) and Life Storage LP (the “Operating Partnership”) have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three month period ended March 31, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.

2. ORGANIZATION

The Parent Company operates as a self-administered and self-managed real estate investment trust (a “REIT”) that owns and operates self-storage facilities throughout the United States. All of the Parent Company’s assets are owned by, and all its operations are conducted through, the Operating Partnership. Life Storage Holdings, Inc., a wholly-owned subsidiary of the Parent Company (“Holdings”), is the sole general partner of the Operating Partnership; the Parent Company is a limited partner of the Operating Partnership, and, through its ownership of Holdings and its limited partnership interest, controls the operations of the Operating Partnership, holding a 99.5% ownership interest therein as of March 31, 2017. The remaining ownership interests in the Operating Partnership (the “Units”) are held by certain former owners of assets acquired by the Operating Partnership. The Parent Company, the Operating Partnership and their consolidated subsidiaries are collectively referred to in this report as the “Company.” In addition, terms such as “we,” “us,” or “our” used in this report may refer to the Company, the Parent Company and/or the Operating Partnership.

At March 31, 2017, we had an ownership interest in, and/or managed 675 self-storage properties in 29 states under the name Life Storage ^®. Among our 675 self-storage properties are 39 properties that we manage for an unconsolidated joint venture (Sovran HHF Storage Holdings LLC) of which we are a 20% owner, 30 properties that we manage for an unconsolidated joint venture (Sovran HHF Storage Holdings II LLC) of which we are a 15% owner, four properties that we manage for an unconsolidated joint venture (191 III Life Storage Holdings LLC) of which we are a 20% owner, one property that we manage for an unconsolidated joint venture (Review Avenue Partners LLC) of which we are a 40% owner, and 36 properties that we manage and have no ownership interest.

We consolidate all wholly-owned subsidiaries. Partially owned subsidiaries and joint ventures are consolidated when we control the entity. Our consolidated financial statements include the accounts of the Parent Company, the Operating Partnership, Life Storage Solutions, LLC (the Parent Company’s taxable REIT subsidiary), Warehouse Anywhere LLC (an entity owned 60% by Life Storage Solutions, LLC), and all other wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated. Investments in joint ventures that we do not control but for which we have significant influence over are accounted for using the equity method.

12

Included in the Parent Company’s consolidated balance sheets are noncontrolling redeemable Operating Partnership Units and included in the Operating Partnership’s consolidated balance sheets are limited partners’ redeemable capital interest at redemption value. These interests are presented in the “mezzanine” section of the consolidated balance sheet because they do not meet the functional definition of a liability or equity under current accounting literature. These represent the outside ownership interests of the limited partners in the Operating Partnership. At March 31, 2017, there were 217,481 noncontrolling redeemable Operating Partnership Units outstanding (217,481 at December 31, 2016). These unitholders are entitled to receive distributions per unit equivalent to the dividends declared per share on the Parent Company’s common stock. The Operating Partnership is obligated to redeem each of these limited partnership units in the Operating Partnership at the request of the holder thereof for cash equal to the fair market value of a share of the Parent Company’s common stock, at the time of such redemption, provided that the Company at its option may elect to acquire any such Unit presented for redemption for one common share or cash. The Company accounts for these noncontrolling redeemable Operating Partnership Units under the provisions of Accounting Standards Codification (ASC) Topic 480-10-S99. The application of the ASC Topic 480-10-S99 accounting model requires the noncontrolling interest to follow normal noncontrolling interest accounting and then be marked to redemption value at the end of each reporting period if higher (but never adjusted below that normal noncontrolling interest accounting amount). The offset to the adjustment to the carrying amount of the noncontrolling interests is reflected in the Company’s dividends in excess of net income and in the Operating Partnership’s general partner and limited partners capital balances. Accordingly, in the accompanying consolidated balance sheets, noncontrolling interests are reflected at redemption value at March 31, 2017 and December 31, 2016, equal to the number of noncontrolling interest units outstanding multiplied by the fair market value of the Parent Company’s common stock at that date. Redemption value exceeded the value determined under the Company’s historical basis of accounting at those dates.

The following is a reconciliation of the Parent Company’s noncontrolling redeemable Operating Partnership Units and the Operating Partnership’s limited partners’ redeemable capital interest for the period:

(dollars in thousands)	Three Months Ended Mar. 31, 2017
Beginning balance	$	18,091
Net income attributable to noncontrolling interest in the Operating Partnership		96
Distributions		(207	)
Adjustment to redemption value		140
Ending balance	$	18,120

Approximately 23% and 14% of the Company’s revenue is derived from stores in the states of Texas and Florida, respectively.

3. STOCK-BASED COMPENSATION

The Company accounts for stock-based compensation under the provisions of ASC Topic 718, “Compensation - Stock Compensation”. The Company recognizes compensation cost in its financial statements for all share based payments granted, modified, or settled during the period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the related vesting period.

For the three months ended March 31, 2017 and 2016, the Company recorded compensation expense (included in general and administrative expense) of $4,000 and $46,000, respectively, related to stock options and $1,589,000 and $1,866,000, respectively, related to amortization of non-vested stock grants and performance-based awards.

No stock options were exercised by employees and directors during the three months ended March 31, 2017 and 2016, and 44,789 and 7,185 shares of non-vested stock, respectively, vested.

During the three months ended March 31, 2017, the Company issued 8,944 shares of non-vested stock to employees which vest over five years. The fair market value on the date of grant of the non-vested stock issued during the three months ended March 31, 2017 was $86.78, resulting in an aggregate fair value of $0.8 million.

During the three months ended March 31, 2017, the Company granted performance-based awards that entitle the recipients to earn up to 17,888 shares if certain performance criteria are achieved over a three year period. The Company estimated the aggregate fair value of the awards on the grant date to be $0.8 million.

4. INVESTMENT IN STORAGE FACILITIES AND INTANGIBLE ASSETS

The Company acquired one facility during the three months ended March 31, 2017. The acquisition of this facility was accounted for as an asset acquisition (see Note 14 for further discussion of the Company’s adoption of the accounting guidance under ASU 2017-01 as of January 1, 2017). The cost of this store, including closing costs, was assigned to land, building, equipment and improvements components based upon their relative fair values.

The purchase price of the facility acquired in 2017 has been preliminarily assigned as follows:

(dollars in thousands)							Consideration paid
States	Number of Properties		Date of Acquisition		Purchase Price		Cash Paid		Value of Operating Partnership Units Issued		Mortgage Assumed		Net Other Liabilities (Assets) Assumed		Land		Building, Equipment, and Improvements		In-Place Customers Leases		Closing Costs Expensed
IL		1		2/23/17	$	10,089	$	10,076	$	—	$	—	$	13	$	771	$	9,318	$	—	$	—

The facility acquired was purchased from an unrelated third party. The operating results of the facility acquired have been included in the Company’s operations since the acquisition date. The $10.1 million of cash paid for the facility includes $0.5 million of deposits that were paid in 2015 when this facility originally went under contract. This amount is excluded from total cash payments for the acquisition of storage facilities in the consolidated statement of cash flows.

Non-cash investing activities during the three months ended March 31, 2017 include the assumption of net other liabilities of $13,000. Non-cash investing activities during the three months ended March 31, 2016 include the issuance of $4.5 million in Operating Partnership Units and the assumption of net other liabilities of $1.3 million.

The Company measures the fair value of in-place customer lease intangible assets based on the Company’s experience with customer turnover and the cost to replace the in-place leases. The Company amortizes in-place customer leases on a straight-line basis over 12 months (the estimated future benefit period). The Company measures the value of trade names, which have an indefinite life and are not amortized, by calculating discounted cash flows utilizing the relief from royalty method.

In-place customer leases are included in other assets on the Company’s consolidated balance sheets as follows:

(Dollars in thousands)	Mar. 31, 2017			Dec. 31, 2016
In-place customer leases	$	75,611		$	75,611
Accumulated amortization		(63,560	)		(50,782	)
Net carrying value at the end of period	$	12,051		$	24,829

15

Amortization expense related to in-place customer leases was $12.8 million and $1.2 million for the three months ended March 31, 2017 and 2016, respectively. The Company expects to record $24.8 million and $0 of amortization expense for the years ended December 31, 2017 and 2018, respectively.

Change in Signage Useful Life Estimates

The change in name of the Company’s storage facilities from Uncle Bob’s Self Storage^® to Life Storage ^® required replacement of signage at all existing storage facilities which are currently included in investment in storage facilities, net on the consolidated balance sheets. The replacement of this signage has been substantially completed as of March 31, 2017. As a result of this replacement of signage, the Company reassessed the estimated useful lives of the then existing signage in 2016. This useful life reassessment resulted in an increase in depreciation expense of approximately $0.5 million in the first quarter of 2017 as depreciation was accelerated over the new useful lives. The Company does not estimate any further impact on depreciation expense as a result of the replacement of the Uncle Bob’s Self Storage^® signage.

The accelerated depreciation reduced basic and diluted earnings per share/unit by approximately $0.01 for the three months ended March 31, 2017.

5. UNSECURED LINE OF CREDIT AND TERM NOTES

Borrowings outstanding on our unsecured line of credit and term notes are as follows:

In January 2016, the Company exercised the expansion feature on its existing amended unsecured credit agreement and increased the revolving credit limit from $300 million to $500 million. The interest rate on the revolving credit facility bears interest at a variable annual rate equal to LIBOR plus a margin based on the Company’s credit rating (at March 31, 2017 the margin is 1.10%), and requires an annual 0.15% facility fee. The Company’s unsecured credit agreement also includes a $325 million unsecured term note maturing June 4, 2020, with the term note bearing interest at LIBOR plus a margin based on the Company’s credit rating (at March 31, 2017 the margin is 1.15%). The interest rate at March 31, 2017 on the Company’s line of credit was approximately 2.08% (1.79% at December 31, 2016). At March 31, 2017, there was $201 million available on the unsecured revolving line of credit. The revolving line of credit has a maturity date of December 10, 2019.

16

On June 20, 2016, the Operating Partnership issued $600 million in aggregate principal amount of 3.50% unsecured senior notes due July 1, 2026 (the “2026 Senior Notes”). The 2026 Senior Notes were issued at a 0.553% discount to par value. Interest on the 2026 Senior Notes is payable semi-annually in arrears on January 1 and July 1, beginning on January 1, 2017. The 2026 Senior Notes are fully and unconditionally guaranteed by the Parent Company. Proceeds received upon issuance, net of discount to par of $3.3 million and underwriting discount and other offering expenses of $5.5 million, totaled $591.2 million. The indenture under which the 2026 Senior Notes were issued restricts the ability of the Company and its subsidiaries to incur debt unless the Company and its consolidated subsidiaries comply with a leverage ratio not to exceed 60% and an interest coverage ratio of more than 1.5:1 on all outstanding debt, after giving effect to the incurrence of the debt. The indenture also restricts the ability of the Company and its subsidiaries to incur secured debt unless the Company and its consolidated subsidiaries comply with a secured debt leverage ratio not to exceed 40% after giving effect to the incurrence of the debt. The indenture also contains other financial and customary covenants, including a covenant not to own unencumbered assets with a value less than 150% of the unsecured indebtedness of the Company and its consolidated subsidiaries. The Company was in compliance with all of the financial covenants under the 2026 Senior Notes as of March 31, 2017.

On July 21, 2016, the Company entered into a $200 million term note maturing July 21, 2028 bearing interest at a fixed rate of 3.67%. The proceeds from this term note were used to repay a portion of the then outstanding balance on the Company’s line of credit.

On April 8, 2014, the Company entered into a $175 million term note maturing April 8, 2024 bearing interest at a fixed rate of 4.533%. The interest rate on the term note increases to 6.283% if the Company is not rated by at least one rating agency or if the Company’s credit rating is downgraded.

In 2011, the Company entered into a $100 million term note maturing August 5, 2021 bearing interest at a fixed rate of 5.54%. The interest rate on the term note increases to 7.29% if the notes are not rated by at least one rating agency, the credit rating on the notes is downgraded or if the Company’s credit rating is downgraded.

The Company had maintained a $150 million unsecured term note maturing April 26, 2016 bearing interest at 6.38%. The Company used a draw on the line of credit to pay off the balance of this note on April 26, 2016.

The line of credit and term notes require the Company to meet certain financial covenants, measured on a quarterly basis, including prescribed leverage, fixed charge coverage, minimum net worth, limitations on additional indebtedness and limitations on dividend payouts. The Company was in compliance with its debt covenants at March 31, 2017.

We believe that if operating results remain consistent with historical levels and levels of other debt and liabilities remain consistent with amounts outstanding at March 31, 2017, the entire availability on the line of credit could be drawn without violating our debt covenants.

The Company’s fixed rate term notes contain a provision that allows for the noteholders to call the debt upon a change of control of the Company at an amount that includes a make whole premium based on rates in effect on the date of the change of control. At this time no change in control is planned or anticipated.

17

Deferred debt issuance costs and the discount on the 2026 Senior Notes are both presented as reductions of term notes in the accompanying consolidated balance sheets at March 31, 2017 and December 31, 2016. Amortization expense related to deferred debt issuance costs was $0.5 million and $0.4 million for the three months ended March 31, 2017 and 2016, respectively, and is included in interest expense in the consolidated statements of income.

6. MORTGAGES PAYABLE AND DEBT MATURITIES

Mortgages payable at March 31, 2017 and December 31, 2016 consist of the following:

(dollars in thousands)	Mar. 31, 2017		Dec. 31, 2016
4.98% mortgage note due January 1, 2021, secured by one self-storage facility with an aggregate net book value of $9.8 million, principal and interest paid monthly (effective interest rate 5.16%)	$	2,953	$	2,966
4.065% mortgage note due April 1, 2023, secured by one self-storage facility with an aggregate net book value of $7.7 million, principal and interest paid monthly (effective interest rate 4.25%)		4,185		4,207
5.26% mortgage note due November 1, 2023, secured by one self-storage facility with an aggregate net book value of $8.1 million, principal and interest paid monthly (effective interest rate 5.50%)		3,985		4,002
5.99% mortgage note due May 1, 2026, secured by one self-storage facility with an aggregate net book value of $6.4 million, principal and interest paid monthly (effective interest rate 6.26%)		1,815		1,852
Total mortgages payable	$	12,938	$	13,027

The table below summarizes the Company’s debt obligations and interest rate derivatives at March 31, 2017. The estimated fair value of financial instruments is subjective in nature and is dependent on a number of important assumptions, including discount rates and relevant comparable market information associated with each financial instrument. The fair value of the fixed rate term notes and mortgage notes were estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. These assumptions are considered Level 2 inputs within the fair value hierarchy as described in Note 8. The carrying values of our variable rate debt instruments approximate their fair values as these debt instruments bear interest at current market rates that approximate market participant rates. This is considered a Level 2 input within the fair value hierarchy. The use of different market assumptions and estimation methodologies may have a material effect on the reported estimated fair value amounts. Accordingly, the estimates presented below are not necessarily indicative of the amounts the Company would realize in a current market exchange.

7. DERIVATIVE FINANCIAL INSTRUMENTS

Interest rate swaps are used to adjust the proportion of total debt that is subject to variable interest rates. The interest rate swaps require the Company to pay an amount equal to a specific fixed rate of interest times a notional principal amount and to receive in return an amount equal to a variable rate of interest times the same notional amount. The notional amounts are not exchanged. Forward starting interest rate swaps are also used by the Company to hedge the risk of changes in the interest-related cash outflows associated with the potential issuance of long-term debt. No other cash payments are made unless the contract is terminated prior to its maturity, in which case the contract would likely be settled for an amount equal to its fair value. The Company enters into interest rate swaps with a number of major financial institutions to minimize counterparty credit risk.

The interest rate swaps qualify and are designated as hedges of the amount of future cash flows related to interest payments on variable rate debt. Therefore, the interest rate swaps are recorded in the consolidated balance sheet at fair value and the related gains or losses are deferred in shareholders’ equity or partners’ capital as Accumulated Other Comprehensive Loss (“AOCL”). These deferred gains and losses are recognized in interest expense during the period or periods in which the related interest payments affect earnings. However, to the extent that the interest rate swaps are not perfectly effective in offsetting the change in value of the interest payments being hedged, the ineffective portion of these contracts is recognized in earnings immediately. Ineffectiveness was de minimis for the three months ended March 31, 2017 and 2016.

The Company has interest rate swap agreements in effect at March 31, 2017 as detailed below to effectively convert a total of $325 million of variable-rate debt to fixed-rate debt.

Notional Amount	Effective Date		Expiration Date		Fixed Rate Paid			Floating Rate Received
$125 Million		9/1/2011		8/1/18		2.3700	%		1 month LIBOR
$100 Million		12/30/11		12/29/17		1.6125	%		1 month LIBOR
$100 Million		9/4/13		9/4/18		1.3710	%		1 month LIBOR
$100 Million		12/29/17		11/29/19		3.9680	%		1 month LIBOR
$125 Million		8/1/18		6/1/20		4.1930	%		1 month LIBOR

In the fourth quarter of 2015, the Company entered into forward starting interest rate swap agreements with a total notional value of $50 million. In the first quarter of 2016, the Company entered into additional forward starting interest rate swap agreements with a total notional value of $100 million. These forward starting interest rate swap agreements were entered into to hedge the risk of changes in the interest-related cash flows associated with the potential issuance of fixed rate long-term debt.

19

In conjunction with the issuance of the $600 million 2026 Senior Notes (see Note 5) in the second quarter of 2016, the Company settled the forward starting swap agreements for a loss of approximately $9.2 million. The loss was recorded as accumulated other comprehensive loss and is being amortized as additional interest expense over the ten-year term of the $600 million 2026 Senior Notes. Consistent with the Company’s accounting policy, the cash outflow related to the settlement of the forward starting swap agreements is reflected as a financing activity in the consolidated statements of cash flows.

The interest rate swap agreements are the only derivative instruments, as defined by FASB ASC Topic 815 “Derivatives and Hedging”, held by the Company. During the three months ended March 31, 2017 and 2016, the net reclassification from AOCL to interest expense was $0.9 million and $1.2 million, respectively, based on payments made under the swap agreements. Based on current interest rates, the Company estimates that payments under the interest rate swaps will be approximately $4.0 million for the 12 months ended March 31, 2018. Payments made under the interest rate swap agreements will be reclassified to interest expense as settlements occur or as payments under the 2026 Senior Notes are made. The fair value of the swap agreements, including accrued interest, was a liability of $11.6 million and $13.0 million at March 31, 2017 and December 31, 2016, respectively.

The Company’s agreements with its interest rate swap counterparties contain provisions pursuant to which the Company could be declared in default of its derivative obligations if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender. The interest rate swap agreements also incorporate other loan covenants of the Company. Failure to comply with the loan covenant provisions would result in the Company being in default on the interest rate swap agreements. As of March 31, 2017, the Company had not posted any collateral related to the interest rate swap agreements. If the Company had breached any of these provisions as of March 31, 2017, it could have been required to settle its obligations under the agreements at their net termination cost of $11.6 million.

The changes in AOCL for the three months ended March 31, 2017 and March 31, 2016 are summarized as follows:

(dollars in thousands)	Three Months Ended Mar. 31, 2017			Three Months Ended Mar. 31, 2016
Accumulated other comprehensive loss beginning of period	$	(21,475	)	$	(14,415	)
Realized loss reclassified from accumulated other comprehensive loss to interest expense		1,119			1,197
Unrealized gain (loss) from changes in the fair value of the effective portion of the interest rate swaps		503			(13,293	)
Income (loss) included in other comprehensive loss		1,622			(12,096	)
Accumulated other comprehensive loss end of period	$	(19,853	)	$	(26,511	)

8. FAIR VALUE MEASUREMENTS

The Company applies the provisions of ASC Topic 820 “Fair Value Measurements and Disclosures” in determining the fair value of its financial and nonfinancial assets and liabilities. ASC Topic 820 establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration. Level 3 inputs are unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

Refer to Note 6 for presentation of the fair values of debt obligations which are disclosed at fair value on a recurring basis.

The following table provides the liabilities carried at fair value measured on a recurring basis as of March 31, 2017 and December 31, 2016 (in thousands):

	Asset (Liability)			Level 1		Level 2			Level 3
March 31, 2017
Interest rate swaps	$	(11,585	)		—	$	(11,585	)		—
December 31, 2016
Interest rate swaps	$	(13,015	)		—	$	(13,015	)		—

Interest rate swaps are over the counter securities with no quoted readily available Level 1 inputs, and therefore are measured at fair value using inputs that are directly observable in active markets and are classified within Level 2 of the valuation hierarchy, using the income approach.

During 2017, assets and liabilities measured at fair value on a non-recurring basis included the assets acquired and liabilities assumed in connection with the acquisition of one storage facility (see note 4). To determine the fair value of land, the Company used prices per acre derived from observed transactions involving comparable land in similar locations, which is considered a Level 2 input. To determine the fair value of buildings, equipment and improvements, the Company used current replacement cost based on information derived from construction industry data by geographic region which is considered a Level 2 input. The replacement cost is then adjusted for the age, condition, and economic obsolescence associated with these assets, which are considered Level 3 inputs. The fair value of in-place customer leases is based on the rent lost due to the amount of time required to replace existing customers and the cost to replace in-place tenants which are based on the Company’s historical experience with turnover at its facilities and on market rental rates and estimated downtime required to replace the in-place leases, all of which are Level 3 inputs. The average downtime is based upon estimated demand information including the number of potential customers exhibited in historical property interest data. Other assets acquired and liabilities assumed in the acquisitions consist primarily of prepaid or accrued real estate taxes and deferred revenues from advance monthly rentals paid by customers. The fair values of these assets and liabilities are based on their carrying values as they typically turn over within one year from the acquisition date and these are Level 3 inputs.

9. INVESTMENT IN JOINT VENTURES

The Company has a 20% ownership interest in Sovran HHF Storage Holdings LLC (“Sovran HHF”), a joint venture that owns 39 self-storage properties that are managed by the Company. During the three months ended March 31, 2017, the Company contributed $3.2 million in cash to the joint venture as its share of capital required to fund the repayment of certain mortgages held by the joint venture. The carrying value of the Company’s investment at March 31, 2017 and December 31, 2016 was $46.8 million and $43.8 million, respectively. As of March 31, 2017, the carrying value of the Company’s investment in Sovran HHF exceeds its share of the underlying equity in net assets of Sovran HHF by approximately $1.7 million as a result of the capitalization of certain acquisition related costs in 2008. This difference is included in the carrying value of the investment.

The Company has a 15% ownership interest in Sovran HHF Storage Holdings II LLC (“Sovran HHF II”), a joint venture that owns 30 self-storage properties that are managed by the Company. The carrying value of the Company’s investment at March 31, 2017 and December 31, 2016 was $13.5 million and $13.5 million, respectively.

The Company holds a 20% ownership in 191 III Holdings LLC (“191 III”), a joint venture that was formed in 2016 to acquire self-storage properties that are managed by the Company. During the three months ended March 31, 2017, 191 III acquired four self-storage facilities. 191 III is under contract at March 31, 2017 to acquire three additional self-storage facilities for $59.2 million, of which the Company is committed to contribute $11.8 million. The purchase of these remaining facilities by 191 III is subject to customary conditions to closing, and there is no assurance that these facilities will be acquired.

14. RECENT ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires an entity to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company has the option to apply the provisions of ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying the new guidance recognized at the date of initial application. We are currently evaluating the alternative methods of adoption and the effect of adopting ASU 2014-09 on our financial statements and related disclosures. We are also in the process of assessing which of our operating revenue streams will be impacted by the adoption of the new standard. Leases are specifically excluded from the scope of ASU 2014-09, therefore the Company does not anticipate that adoption of the new standard will have any impact on the timing or amounts of the Company’s rental revenue from customers which is a substantial portion of the Company’s total operating revenues. The Company intends to make a decision on which method of adoption will be elected by the end of the second quarter of 2017.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. This guidance revises existing practice related to accounting for leases under Accounting Standards Codification Topic 840 Leases (ASC 840) for both lessees and lessors. The new guidance in ASU 2016-02 requires lessees to recognize a right-of-use asset and a lease liability for virtually all of their leases (other than leases that meet the definition of a short-term lease). The lease liability will be equal to the present value of lease payments and the right-of-use asset will be based on the lease liability, subject to adjustment such as for initial direct costs. For income statement purposes, the new standard retains a dual model similar to ASC 840, requiring leases to be classified as either operating or finance. For lessees, operating leases will result in straight-line expense (similar to current accounting by lessees for operating leases under ASC 840) while finance leases will result in a front-loaded expense pattern (similar to current accounting by lessees for capital leases under ASC 840). While the new standard maintains similar accounting for lessors as under ASC 840, the new standard reflects updates to, among other things, align with certain changes to the lessee model. ASU 2016-02 is effective for fiscal years and interim periods, within those years, beginning after December 15, 2018. Early adoption is permitted for all entities. The Company has not yet completed its assessment of the impact that the adoption of ASU 2016-02 will have on its consolidated financial statements.

In March 2016, the FASB issued ASU 2016-06, “Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments”. ASU 2016-06 simplifies the embedded derivative analysis for debt instruments containing contingent call or put options by removing the requirement to assess whether a contingent event is related to interest rates or credit risks. ASU 2016-06 is effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2016. The implementation of this update did not result in any changes to our consolidated financial statements.

In March 2016, the FASB issued ASU 2016-07, “Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting”. ASU 2016-07 eliminates the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an adjustment must be made to the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held.

28

ASU 2016-07 is effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2016. The implementation of this update did not result in any changes to our consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting” as part of its simplification initiative, which involves several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2016. The implementation of this update did not result in any changes to our consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a Consensus of the Emerging Issues Task Force)” in an effort to reduce existing diversity in practice related to the classification of certain cash receipts and cash payments on the statements of cash flows. The guidance addresses the classification of cash flows related to, among other things, distributions received from equity method investees. The amendments in this update are effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. ASU 2016-15 is not expected to have a material impact on the Company’s consolidated financial statements.

In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash (a Consensus of the Emerging Issues Task Force)” which requires restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this update are effective for annual periods beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption of this update is permitted. Other than modifications to the statement of cash flows, the adoption of ASU 2016-18 is not expected to have a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business” which is intended to assist entities with evaluating whether a set of transferred assets and activities is a business. The amendments in this update are effective for annual periods beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption of this update is permitted and the Company adopted this update effective January 1, 2017. The adoption of ASU 2017-01 is expected to have potential impact on the accounting treatment of properties acquired subsequent to the adoption date. Property acquisitions treated as business combinations under current guidance may no longer be treated as business combinations subsequent to the adoption of ASU 2017-01. To the extent that properties that we acquire do not meet the definition of a “business” under ASU 2017-01, future acquisitions of properties may be accounted for as asset acquisitions resulting in the capitalization of acquisition costs incurred in connection with these transactions and the allocation of the purchase price and related acquisition costs to the assets acquired based on their relative fair values. There were no properties acquired in the first quarter of 2017 that would have been accounted for as business combinations prior to the adoption of ASU 2017-01.

29

In February 2017, the FASB issued ASU 2017-05, “Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets” which clarifies the scope and application of ASC 610-20 on the sale or transfer of nonfinancial assets, including real estate, and in substance nonfinancial assets to noncustomers, including partial sales. The amendments in this update are effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The Company has not yet completed its assessment of the impact that the adoption of ASU 2017-05 will have on its consolidated financial statements.

15. COMMITMENT AND CONTINGENCIES

At March 31, 2017, the Company was under contract to acquire three self-storage facilities for an aggregate purchase price of approximately $37.6 million. The purchase of these facilities is subject to customary conditions to closing, and there is no assurance that these facilities will be acquired. On April 3, 2017, the Company entered into a three year lease for one of these self-storage facilities, effectively cancelling the purchase contract for this facility which would have included consideration of $14.1 million. Annual minimum lease payments under this lease total $0.6 million.

At March 31, 2017, 191 III was under contract to purchase three self-storage facilities for an aggregate purchase price of $59.2 million, of which the Company is committed to contribute a total of $11.8 million. The purchase of these facilities by 191 III is subject to customary conditions to closing, and there is no assurance that these facilities will be acquired.

On or about August 25, 2014, a putative class action was filed against the Company in the Superior Court of New Jersey Law Division Burlington County. The action seeks to obtain declaratory, injunctive and monetary relief for a class of consumers based upon alleged violations by the Company of the New Jersey Truth in Customer Contract, Warranty and Notice Act, the New Jersey Consumer Fraud Act and the New Jersey Insurance Producer Licensing Act. On October 17, 2014, the action was removed from the Superior Court of New Jersey Law Division Burlington County to the United States District Court for the District of New Jersey. The Company brought a motion to partially dismiss the complaint for failure to state a claim, and on July 16, 2015, the Company’s motion was granted in part and denied in part. On October 20, 2016, the complaint was amended to add a claim that the Company’s insurance program violates New Jersey consumer protection laws. The Company intends to vigorously defend the action, and the possibility of any adverse outcome cannot be determined at this time.

16. SUBSEQUENT EVENTS

On April 5, 2017 the Company declared a quarterly dividend of $1.00 per common share. The dividend was paid on April 26, 2017 to shareholders of record on April 18, 2017. The total dividend paid amounted to $46.4 million.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of the Company’s consolidated financial condition and results of operations should be read in conjunction with the unaudited financial statements and notes thereto included elsewhere in this report.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

When used in this discussion and elsewhere in this document, the words “intends,” “believes,” “expects,” “anticipates,” and similar expressions are intended to identify “forward-looking statements” within the meaning of that term in Section 27A of the Securities Act of 1933 and in Section 21E of the Securities Exchange Act of 1934. Such forward-looking statements involve known and unknown risks, uncertainties and other factors, which may cause the actual results, performance or achievements of the Company to be materially different from those expressed or implied by such forward-looking statements. Such factors include, but are not limited to, the effect of competition from new self-storage facilities, which would cause rents and occupancy rates to decline; the Company’s ability to evaluate, finance and integrate acquired businesses into the Company’s existing business and operations; the Company’s ability to effectively compete in the industry in which it does business; the Company’s existing indebtedness may mature in an unfavorable credit environment, preventing refinancing or forcing refinancing of the indebtedness on terms that are not as favorable as the existing terms; interest rates may fluctuate, impacting costs associated with the Company’s outstanding floating rate debt; the Company’s ability to comply with debt covenants; any future ratings on the Company’s debt instruments; regional concentration of the Company’s business may subject it to economic downturns in the states of Florida and Texas; the Company’s reliance on its call center; the Company’s cash flow may be insufficient to meet required payments of operating expenses, principal, interest and dividends; and tax law changes that may change the taxability of future income.

RESULTS OF OPERATIONS

FOR THE PERIOD JANUARY 1, 2017 THROUGH MARCH 31, 2017, COMPARED TO THE PERIOD JANUARY 1, 2016 THROUGH MARCH 31, 2016

We recorded rental revenues of $118.6 million for the three months ended March 31, 2017, an increase of $27.1 million or 29.6% when compared to rental revenues of $91.5 million for the same period in 2016. Of the increase in rental revenue, $2.7 million resulted from a 3.2% increase in rental revenues at the 435 core properties considered in same store sales (those properties included in the consolidated results of operations since January 1, 2016, excluding the properties we sold in 2016, and excluding stores not yet stabilized and three stores significantly impacted by flooding in 2016). The increase in same store rental revenues was a result of a 20 basis point increase in average occupancy and a 2.7% increase in rental income per square foot. The remaining increase in rental revenue of $24.4 million resulted from the revenues from the acquisition of properties completed since January 1, 2016 and stores not yet stabilized. Other operating income, which includes merchandise sales, insurance administrative fees, truck rentals, management fees and acquisition fees, increased by $2.1 million for the three months ended March 31, 2017 compared to the same period in 2016 primarily as a result of increased administrative fees earned on customer insurance.

31

Property operations and maintenance expenses increased $6.9 million or 30.3% in the three months ended March 31, 2017 compared to the same period in 2016. The 435 core properties considered in the same store pool experienced a $0.4 million or 2.1% increase in operating expenses primarily as a result of higher payroll and benefit costs. In addition to the same store operating expense increase, operating expenses increased $6.5 million from the acquisition of properties completed since January 1, 2016 and stores not yet stabilized. Real estate tax expense increased $3.9 million as a result of a 5.5% increase in property taxes on the 435 same store pool and the inclusion of taxes on the properties acquired in 2016 and 2017.

Net operating income increased $18.4 million or 28.0% as a result of a 3.2% increase in our same store net operating income and the acquisitions completed since January 1, 2016.

Net operating income or “NOI” is a non-GAAP (generally accepted accounting principles) financial measure that we define as total continuing revenues less continuing property operating expenses. NOI also can be calculated by adding back to net income: interest expense, impairment and casualty losses, operating lease expense, depreciation and amortization expense, acquisition related costs, general and administrative expense, and deducting from net income: income from discontinued operations, interest income, gain on sale of real estate, and equity in income of joint ventures. We believe that NOI is a meaningful measure to investors in evaluating our operating performance because we utilize NOI in making decisions with respect to capital allocations, in determining current property values, and in comparing period-to-period and market-to-market property operating results. Additionally, NOI is widely used in the real estate industry and the self-storage industry to measure the performance and value of real estate assets without regard to various items included in net income that do not relate to or are not indicative of operating performance, such as depreciation and amortization, which can vary depending on accounting methods and the book value of assets. NOI should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with GAAP, such as total revenues, operating income and net income. There are material limitations to using a measure such as NOI, including the difficulty associated with comparing results among more than one company and the inability to analyze certain significant items, including depreciation and interest expense, that directly affect our net income. We compensate for these limitations by considering the economic effect of the excluded expense items independently as well as in connection with our analysis of net income. The following table reconciles our net income presented in the consolidated financial statements to NOI generated by our self-storage facilities for the three months ended March 31, 2017 and 2016.

Our 2017 same store results consist of only those properties that have been owned by the Company and included in our consolidated results since January 1, 2016, excluding stores purchased prior to January 1, 2016 that have not yet stabilized and three stores significantly impacted by flooding in 2016. The following table sets forth operating data for our 435 same store properties. These results provide information relating to property operating changes without the effects of acquisitions.

Quarterly same store move ins		39,321		41,380		(2,059	)
Quarterly same store move outs		37,059		38,286		(1,227	)

We believe the decrease in same store move ins was due to increased competition and customer rate sensitivity in certain markets. We believe the decrease in same store move outs was a result of customers increasing their length of stay.

General and administrative expenses for the three months ended March 31, 2017 increased $1.0 million or 9.3% compared with the three months ended March 31, 2016. The key drivers of the increase were a $0.7 million increase in costs related to the Company’s name change and a $0.4 million increase in salaries and benefits.

There were no acquisition related costs recorded during the three months ended March 31, 2017. Acquisition related costs were $2.4 million for the three months ended March 31, 2016 as a result of the acquisition of 25 stores during that period.

Depreciation and amortization expense increased to $37.6 million in the three months ended March 31, 2017 from $16.4 million in the same period of 2016, primarily as a result of amortization of customer lists and depreciation on the properties acquired in 2016 and 2017.

Total interest expense increased $6.1 million in the three months ended March 31, 2017 as compared to the same period in 2016 primarily as a result of interest on the $600 million 3.5% senior notes issued in June 2016 and the $200 million 3.67% term loan entered into in July 2016, partially offset by reduced interest costs as a result of the payoff of the $150 million 6.38% term loan in April 2016 with a draw on our line of credit which carries a lower interest rate.

FUNDS FROM OPERATIONS

We believe that Funds from Operations (“FFO”) provides relevant and meaningful information about our operating performance that is necessary, along with net (loss) earnings and cash flows, for an understanding of our operating results. FFO adds back historical cost depreciation, which assumes the value of real estate assets diminishes predictably in the future. In fact, real estate asset values increase or decrease with market conditions. Consequently, we believe FFO is a useful supplemental measure in evaluating our operating performance by disregarding (or adding back) historical cost depreciation.

FFO is defined by the National Association of Real Estate Investment Trusts, Inc. (“NAREIT”) as net income available to common shareholders computed in accordance with generally accepted accounting principles (“GAAP”), excluding gains or losses on sales of properties, plus impairment of real estate assets, plus depreciation and amortization and after adjustments to record unconsolidated partnerships and joint ventures on the same basis. We believe that to further understand our performance FFO should be compared with our reported net income and cash flows in accordance with GAAP, as presented in our consolidated financial statements.

In October and November of 2011, NAREIT issued guidance for reporting FFO that reaffirmed NAREIT’s view that impairment write-downs of depreciable real estate should be excluded from the computation of FFO. This view is based on the fact that impairment write-downs are akin to and effectively reflect the early recognition of losses on prospective sales of depreciable property or represent adjustments of previously charged depreciation. Since depreciation of real estate and gains/losses from sales are excluded from FFO, it is NAREIT’s view that it is consistent and appropriate for write-downs of depreciable real estate to also be excluded. Our calculation of FFO excludes impairment write-downs of investments in storage facilities.

Our computation of FFO may not be comparable to FFO reported by other REITs or real estate companies that do not define the term in accordance with the current NAREIT definition or that interpret the current NAREIT definition differently. FFO does not represent cash generated from operating activities determined in accordance with GAAP, and should not be considered as an alternative to net income (determined in accordance with GAAP) as an indication of our performance, as an alternative to net cash flows from operating activities (determined in accordance with GAAP) as a measure of our liquidity, or as an indicator of our ability to make cash distributions.

LIQUIDITY AND CAPITAL RESOURCES

Our line of credit and term notes require us to meet certain financial covenants measured on a quarterly basis, including prescribed leverage, fixed charge coverage, minimum net worth, limitations on additional indebtedness, and limitations on dividend payouts. At March 31, 2017, the Company was in compliance with all debt covenants. In the event that the Company violates its debt covenants in the future, the amounts due under the agreements could be callable by the lenders and could adversely affect our credit rating requiring us to pay higher interest and other debt-related costs. We believe that if operating results remain consistent with historical levels and levels of other debt and liabilities remain consistent with amounts outstanding at March 31, 2017, the entire availability under our line of credit could be drawn without violating our debt covenants.

Our ability to retain cash flow is limited because we operate as a REIT. In order to maintain our REIT status, a substantial portion of our operating cash flow must be used to pay dividends to our shareholders. We believe that our internally generated net cash provided by operating activities and the availability on our line of credit will be sufficient to fund ongoing operations, capital improvements, dividends and debt service requirements.

Cash flows from operating activities were $28.0 million and $37.9 million for the three months ended March 31, 2017 and 2016, respectively. The decrease in operating cash flows in the 2017 period compared to the 2016 period was primarily due an increase in cash payments to settle liabilities, including payments for interest, partially offset by the increase in net income after adjusting for non-cash items.

Cash used in investing activities was $52.7 million and $342.6 million for the three months ended March 31, 2017 and 2016, respectively. The decrease in cash used in investing activities in the 2017 period compared to the 2016 period was primarily due to the decreased volume of acquisitions in the first three months of 2017 as compared to the same period in 2016.

Cash provided by financing activities was $5.8 million for the three months ended March 31, 2017 compared to $304.0 million for the three months ended March 31, 2016. On January 20, 2016, the Company completed the public offering of 2,645,000 shares of its common stock at $105.75 per share. Net proceeds to the Company after deducting underwriting discounts and commissions and offering expenses were approximately $269.7 million. The Company used the net proceeds from the offering to repay a portion of the indebtedness then outstanding on the Company’s unsecured line of credit which had been used to fund acquisitions in the first quarter of 2016.

In January 2016, the Company exercised the expansion feature of its existing amended unsecured credit agreement and increased the revolving credit limit from $300 million to $500 million. The interest rate on the revolving credit facility bears interest at a variable rate equal to LIBOR plus a margin based on the Company’s credit rating (at March 31, 2017 the margin is 1.10%), and requires a 0.15% facility fee. The Company’s unsecured credit agreement also includes a $325 million unsecured term note maturing June 4, 2020, with the term note bearing interest at LIBOR plus a margin based on the Company’s credit rating (at March 31, 2017 the margin is 1.15%). The interest rate at March 31, 2017 on the Company’s line of credit was approximately 2.08% (1.79% at December 31, 2016). At March 31, 2017, there was $201 million available on the unsecured line of credit. The revolving line of credit has a maturity date of December 10, 2019.

35

Our line of credit facility and term notes have an investment grade rating from Standard and Poor’s (BBB) and Moody’s (Baa2).

In addition to the unsecured financing mentioned above, our consolidated financial statements also include $12.9 million of mortgages payable that are secured by four storage facilities.

The Company maintains a continuous equity offering program (“Equity Program”) with Wells Fargo Securities, LLC (“Wells Fargo”), Jefferies LLC (“Jefferies”), SunTrust Robinson Humphrey, Inc. (“SunTrust”), Piper Jaffray & Co. (“Piper”), HSBC Securities (USA) Inc. (“HSBC”), and BB&T Capital Markets, a division of BB&T Securities, LLC (“BB&T”), pursuant to which the Company may sell from time to time up to $225 million in aggregate offering price of shares of the Company’s common stock. Actual sales under the Equity Program will depend on a variety of factors and conditions, including, but not limited to, market conditions, the trading price of the Company’s common stock, and determinations of the appropriate sources of funding for the Company. The Company expects to continue to offer, sell, and issue shares of common stock under the Equity Program from time to time based on various factors and conditions, although the Company is under no obligation to sell any shares under the Equity Program.

During the three months ended March 31, 2017 and 2016, the Company did not issue any shares of common stock under the Equity Program. As of March 31, 2017, the Company had $59.3 million available for issuance under the Equity Program which is scheduled to expire in May 2017.

In 2013, the Company implemented a Dividend Reinvestment Plan. The Company issued 52,304 shares under the plan during the three months ended March 31, 2017.

Future acquisitions, our expansion and enhancement program, and share repurchases are expected to be funded with draws on our line of credit, issuance of common and preferred stock, the issuance of unsecured term notes, sale of properties, and private placement solicitation of joint venture equity. Should the capital markets deteriorate, we may have to curtail acquisitions, our expansion and enhancement program and share repurchases.

ACQUISITION AND DISPOSITION OF PROPERTIES

In the three months ended March 31, 2017, the Company acquired one self-storage facility comprising 78,000 square feet in Illinois for a purchase price of $10.1 million. As this facility was recently constructed, the capitalization rate on this purchase was 0%.

In 2016, the Company acquired 122 self-storage facilities comprising 9.4 million square feet in Arizona (1), California (22), Colorado (6), Connecticut (2), Florida (11), Illinois (25), Massachusetts (1), Mississippi (1), New Hampshire (5), Nevada (17), New York (4), Pennsylvania (1), South Carolina (1), Texas (23), Utah (1), and Wisconsin (1) for a total purchase price of $1,783.9 million. Based on the trailing financial information of the entities from which the properties were acquired, the weighted average capitalization rate was 3.6% on these purchases and ranged from 0% on recently constructed facilities to 6.7% on mature facilities.

During 2016 the Company sold eight non-strategic properties with a carrying value of $18.8 million and received cash proceeds of $34.1 million, resulting in a $15.3 million gain on sale.

36

We may seek to sell additional properties to third parties or joint venture partners in 2017.

FUTURE ACQUISITION AND DEVELOPMENT PLANS

Our external growth strategy is to increase the number of facilities we own by acquiring suitable facilities in markets in which we already have operations, or to expand into new markets by acquiring several facilities at once in those new markets. We are actively pursuing acquisitions in 2017, and at March 31, 2017, we were under contract to acquire three self-storage facilities for aggregate consideration of approximately $37.6 million. On April 3, 2017, the Company entered into a three year lease for one of these self-storage facilities, effectively cancelling the purchase contract for this facility which would have included consideration of $14.1 million. Annual minimum lease payments under this lease total $0.6 million.

In the three months ended March 31, 2017, we added 73,000 square feet to existing properties for a total cost of approximately $4.8 million. We plan to complete an additional $35.2 million of expansions and enhancements to our existing facilities in 2017, of which $13.1 million was paid as of March 31, 2017.

We also expect to continue making capital expenditures on our properties. This includes roofing, paving, and remodeling of store offices. For the first three months of 2017 we spent approximately $14.6 million on such improvements and we expect to spend approximately $26.0 million for the remainder of 2017.

REIT QUALIFICATION AND DISTRIBUTION REQUIREMENTS

As a REIT, we are not required to pay federal income tax on income that we distribute to our shareholders, provided that we satisfy certain requirements, including distributing at least 90% of our REIT taxable income for a taxable year. These distributions must be made in the year to which they relate, or in the following year if declared before we file our federal income tax return, and if they are paid not later than the date of the first regular dividend of the following year. As a REIT, we must derive at least 95% of our total gross income from income related to real property, interest and dividends.

Although we currently intend to operate in a manner designed to qualify as a REIT, it is possible that future economic, market, legal, tax or other considerations may cause our Board of Directors to revoke our REIT election.

UMBRELLA PARTNERSHIP REIT

We are formed as an Umbrella Partnership Real Estate Investment Trust (“UPREIT”) and, as such, have the ability to issue Operating Partnership Units in exchange for properties sold by independent owners. By utilizing such Units as currency in facility acquisitions, we may obtain more favorable pricing or terms due to the seller’s ability to partially defer their income tax liability. As of March 31, 2017, 217,481 Units are outstanding. These Units had been issued in exchange for self-storage properties at the request of the sellers.

37

INTEREST RATE RISK

The primary market risk to which we believe we are exposed is interest rate risk, which may result from many factors, including government monetary and tax policies, domestic and international economic and political considerations, and other factors that are beyond our control.

We have entered into interest rate swap agreements in order to mitigate the effects of fluctuations in interest rates on our variable rate debt. The LIBOR base rates have been contractually fixed on $325 million of our debt through the interest rate swap termination dates. See Note 7 to our consolidated financial statements appearing elsewhere in this quarterly report on Form 10-Q.

Through September 2018, $325 million of our $624 million of floating rate unsecured debt is on a fixed rate basis after taking into account our interest rate swap agreements. Based on our outstanding unsecured floating rate debt of $624 million at March 31, 2017, and taking into account our interest rate swap agreements, a 100 basis point increase in interest rates would have a $3.0 million effect on our annual interest expense. These amounts were determined by considering the impact of the hypothetical interest rates on our borrowing cost and our interest rate swap agreements in effect on March 31, 2017. These analyses do not consider the effects of the reduced level of overall economic activity that could exist in such an environment. Further, in the event of a change of such magnitude, we would consider taking actions to further mitigate our exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, the sensitivity analysis assumes no changes in our capital structure.

INFLATION

We do not believe that inflation has had or will have a direct effect on our operations. Substantially all of the leases at the facilities are on a month-to-month basis which provides us with the opportunity to increase rental rates as each lease matures.

SEASONALITY

Our revenues typically have been higher in the third and fourth quarters, primarily because self-storage facilities tend to experience greater occupancy during the late spring, summer and early fall months due to the greater incidence of residential moves and college student activity during these periods. However, we believe that our customer mix, diverse geographic locations, rental structure and expense structure provide adequate protection against undue fluctuations in cash flows and net revenues during off-peak seasons. Thus, we do not expect seasonality to affect materially distributions to shareholders.

Item 4. Controls and Procedures

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

Parent Company

An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, has been conducted under the supervision of and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer. Based on that evaluation, our management, including the Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were effective at March 31, 2017. There have not been changes in the Company’s internal controls or in other factors that could significantly affect these controls during the quarter ended March 31, 2017.

Changes in Internal Control over Financial Reporting

There have not been any changes in the Company’s internal control over financial reporting (as defined in 13a-15(f) and 15d-15(f) promulgated under the Securities Exchange Act of 1934) that occurred during the Company’s most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Operating Partnership

An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, has been conducted under the supervision of and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer. Based on that evaluation, our management, including the Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were effective at March 31, 2017. There have not been changes in the Operating Partnership’s internal controls or in other factors that could significantly affect these controls during the quarter ended March 31, 2017.

Changes in Internal Control over Financial Reporting

There have not been any changes in the Operating Partnership’s internal control over financial reporting (as defined in 13a-15(f) and 15d-15(f) promulgated under the Securities Exchange Act of 1934) that occurred during the Operating Partnership’s most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Operating Partnership’s internal control over financial reporting.

PART II. Other Information

Item 1. Legal Proceedings

On or about August 25, 2014, a putative class action was filed against the Company in the Superior Court of New Jersey Law Division Burlington County. The action seeks to obtain declaratory, injunctive and monetary relief for a class of consumers based upon alleged violations by the Company of the New Jersey Truth in Customer Contract, Warranty and Notice Act, the New Jersey Consumer Fraud Act and the New Jersey Insurance Producer Licensing Act.

39

On October 17, 2014, the action was removed from the Superior Court of New Jersey Law Division Burlington County to the United States District Court for the District of New Jersey. The Company brought a motion to partially dismiss the complaint for failure to state a claim, and on July 16, 2015, the Company’s motion was granted in part and denied in part. On October 20, 2016, the complaint was amended to add a claim that the Company’s insurance program violates New Jersey consumer protection laws. The Company intends to vigorously defend the action, and the possibility of any adverse outcome cannot be determined at this time.

Item 1A. Risk Factors

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2016, which could materially affect our business, financial condition or future results. The risks described in our Annual Report on Form 10-K are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and operating results.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization

2. ORGANIZATION

The Parent Company operates as a self-administered and self-managed real estate investment trust (a “REIT”) that owns and operates self-storage facilities throughout the United States. All of the Parent Company’s assets are owned by, and all its operations are conducted through, the Operating Partnership. Life Storage Holdings, Inc., a wholly-owned subsidiary of the Parent Company (“Holdings”), is the sole general partner of the Operating Partnership; the Parent Company is a limited partner of the Operating Partnership, and, through its ownership of Holdings and its limited partnership interest, controls the operations of the Operating Partnership, holding a 99.5% ownership interest therein as of March 31, 2017. The remaining ownership interests in the Operating Partnership (the “Units”) are held by certain former owners of assets acquired by the Operating Partnership. The Parent Company, the Operating Partnership and their consolidated subsidiaries are collectively referred to in this report as the “Company.” In addition, terms such as “we,” “us,” or “our” used in this report may refer to the Company, the Parent Company and/or the Operating Partnership.

At March 31, 2017, we had an ownership interest in, and/or managed 675 self-storage properties in 29 states under the name Life Storage ^®. Among our 675 self-storage properties are 39 properties that we manage for an unconsolidated joint venture (Sovran HHF Storage Holdings LLC) of which we are a 20% owner, 30 properties that we manage for an unconsolidated joint venture (Sovran HHF Storage Holdings II LLC) of which we are a 15% owner, four properties that we manage for an unconsolidated joint venture (191 III Life Storage Holdings LLC) of which we are a 20% owner, one property that we manage for an unconsolidated joint venture (Review Avenue Partners LLC) of which we are a 40% owner, and 36 properties that we manage and have no ownership interest.

We consolidate all wholly-owned subsidiaries. Partially owned subsidiaries and joint ventures are consolidated when we control the entity. Our consolidated financial statements include the accounts of the Parent Company, the Operating Partnership, Life Storage Solutions, LLC (the Parent Company’s taxable REIT subsidiary), Warehouse Anywhere LLC (an entity owned 60% by Life Storage Solutions, LLC), and all other wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated. Investments in joint ventures that we do not control but for which we have significant influence over are accounted for using the equity method.

Included in the Parent Company’s consolidated balance sheets are noncontrolling redeemable Operating Partnership Units and included in the Operating Partnership’s consolidated balance sheets are limited partners’ redeemable capital interest at redemption value. These interests are presented in the “mezzanine” section of the consolidated balance sheet because they do not meet the functional definition of a liability or equity under current accounting literature. These represent the outside ownership interests of the limited partners in the Operating Partnership. At March 31, 2017, there were 217,481 noncontrolling redeemable Operating Partnership Units outstanding (217,481 at December 31, 2016). These unitholders are entitled to receive distributions per unit equivalent to the dividends declared per share on the Parent Company’s common stock. The Operating Partnership is obligated to redeem each of these limited partnership units in the Operating Partnership at the request of the holder thereof for cash equal to the fair market value of a share of the Parent Company’s common stock, at the time of such redemption, provided that the Company at its option may elect to acquire any such Unit presented for redemption for one common share or cash. The Company accounts for these noncontrolling redeemable Operating Partnership Units under the provisions of Accounting Standards Codification (ASC) Topic 480-10-S99. The application of the ASC Topic 480-10-S99 accounting model requires the noncontrolling interest to follow normal noncontrolling interest accounting and then be marked to redemption value at the end of each reporting period if higher (but never adjusted below that normal noncontrolling interest accounting amount). The offset to the adjustment to the carrying amount of the noncontrolling interests is reflected in the Company’s dividends in excess of net income and in the Operating Partnership’s general partner and limited partners capital balances. Accordingly, in the accompanying consolidated balance sheets, noncontrolling interests are reflected at redemption value at March 31, 2017 and December 31, 2016, equal to the number of noncontrolling interest units outstanding multiplied by the fair market value of the Parent Company’s common stock at that date. Redemption value exceeded the value determined under the Company’s historical basis of accounting at those dates.    

The following is a reconciliation of the Parent Company’s noncontrolling redeemable Operating Partnership Units and the Operating Partnership’s limited partners’ redeemable capital interest for the period:

Beginning balance	$	18,091
Net income attributable to noncontrolling interest in the Operating Partnership		96

Approximately 23% and 14% of the Company’s revenue is derived from stores in the states of Texas and Florida, respectively.

Stock Based Compensation

3. STOCK-BASED COMPENSATION

The Company accounts for stock-based compensation under the provisions of ASC Topic 718, “Compensation - Stock Compensation”. The Company recognizes compensation cost in its financial statements for all share based payments granted, modified, or settled during the period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the related vesting period.

For the three months ended March 31, 2017 and 2016, the Company recorded compensation expense (included in general and administrative expense) of $4,000 and $46,000, respectively, related to stock options and $1,589,000 and $1,866,000, respectively, related to amortization of non-vested stock grants and performance-based awards.

No stock options were exercised by employees and directors during the three months ended March 31, 2017 and 2016, and 44,789 and 7,185 shares of non-vested stock, respectively, vested.

During the three months ended March 31, 2017, the Company issued 8,944 shares of non-vested stock to employees which vest over five years. The fair market value on the date of grant of the non-vested stock issued during the three months ended March 31, 2017 was $86.78, resulting in an aggregate fair value of $0.8 million.

During the three months ended March 31, 2017, the Company granted performance-based awards that entitle the recipients to earn up to 17,888 shares if certain performance criteria are achieved over a three year period. The Company estimated the aggregate fair value of the awards on the grant date to be $0.8 million.

(dollars in thousands)
Cost:
Beginning balance	$	4,243,308
Acquisition of storage facilities		10,089
Improvements and equipment additions		19,345

The Company acquired one facility during the three months ended March 31, 2017. The acquisition of this facility was accounted for as an asset acquisition (see Note 14 for further discussion of the Company’s adoption of the accounting guidance under ASU 2017-01 as of January 1, 2017). The cost of this store, including closing costs, was assigned to land, building, equipment and improvements components based upon their relative fair values.

The purchase price of the facility acquired in 2017 has been preliminarily assigned as follows:

(dollars in thousands)							Consideration paid
States	Number of Properties		Date of Acquisition		Purchase Price		Cash Paid		Value of Operating Partnership Units Issued		Mortgage Assumed		Net Other Liabilities (Assets) Assumed		Land		Building, Equipment, and Improvements		In-Place Customers Leases		Closing Costs Expensed

The facility acquired was purchased from an unrelated third party. The operating results of the facility acquired have been included in the Company’s operations since the acquisition date. The $10.1 million of cash paid for the facility includes $0.5 million of deposits that were paid in 2015 when this facility originally went under contract. This amount is excluded from total cash payments for the acquisition of storage facilities in the consolidated statement of cash flows.

Non-cash investing activities during the three months ended March 31, 2017 include the assumption of net other liabilities of $13,000. Non-cash investing activities during the three months ended March 31, 2016 include the issuance of $4.5 million in Operating Partnership Units and the assumption of net other liabilities of $1.3 million.

The Company measures the fair value of in-place customer lease intangible assets based on the Company’s experience with customer turnover and the cost to replace the in-place leases. The Company amortizes in-place customer leases on a straight-line basis over 12 months (the estimated future benefit period). The Company measures the value of trade names, which have an indefinite life and are not amortized, by calculating discounted cash flows utilizing the relief from royalty method.

In-place customer leases are included in other assets on the Company’s consolidated balance sheets as follows:

(Dollars in thousands)	Mar. 31, 2017			Dec. 31, 2016
In-place customer leases	$	75,611		$	75,611
Accumulated amortization		(63,560	)		(50,782	)
Net carrying value at the end of period	$	12,051		$	24,829

Amortization expense related to in-place customer leases was $12.8 million and $1.2 million for the three months ended March 31, 2017 and 2016, respectively. The Company expects to record $24.8 million and $0 of amortization expense for the years ended December 31, 2017 and 2018, respectively.

Change in Signage Useful Life Estimates

The change in name of the Company’s storage facilities from Uncle Bob’s Self Storage^® to Life Storage ^® required replacement of signage at all existing storage facilities which are currently included in investment in storage facilities, net on the consolidated balance sheets. The replacement of this signage has been substantially completed as of March 31, 2017. As a result of this replacement of signage, the Company reassessed the estimated useful lives of the then existing signage in 2016. This useful life reassessment resulted in an increase in depreciation expense of approximately $0.5 million in the first quarter of 2017 as depreciation was accelerated over the new useful lives. The Company does not estimate any further impact on depreciation expense as a result of the replacement of the Uncle Bob’s Self Storage^® signage.

The accelerated depreciation reduced basic and diluted earnings per share/unit by approximately $0.01 for the three months ended March 31, 2017.

In January 2016, the Company exercised the expansion feature on its existing amended unsecured credit agreement and increased the revolving credit limit from $300 million to $500 million. The interest rate on the revolving credit facility bears interest at a variable annual rate equal to LIBOR plus a margin based on the Company’s credit rating (at March 31, 2017 the margin is 1.10%), and requires an annual 0.15% facility fee. The Company’s unsecured credit agreement also includes a $325 million unsecured term note maturing June 4, 2020, with the term note bearing interest at LIBOR plus a margin based on the Company’s credit rating (at March 31, 2017 the margin is 1.15%). The interest rate at March 31, 2017 on the Company’s line of credit was approximately 2.08% (1.79% at December 31, 2016). At March 31, 2017, there was $201 million available on the unsecured revolving line of credit. The revolving line of credit has a maturity date of December 10, 2019.

On June 20, 2016, the Operating Partnership issued $600 million in aggregate principal amount of 3.50% unsecured senior notes due July 1, 2026 (the “2026 Senior Notes”). The 2026 Senior Notes were issued at a 0.553% discount to par value. Interest on the 2026 Senior Notes is payable semi-annually in arrears on January 1 and July 1, beginning on January 1, 2017. The 2026 Senior Notes are fully and unconditionally guaranteed by the Parent Company. Proceeds received upon issuance, net of discount to par of $3.3 million and underwriting discount and other offering expenses of $5.5 million, totaled $591.2 million. The indenture under which the 2026 Senior Notes were issued restricts the ability of the Company and its subsidiaries to incur debt unless the Company and its consolidated subsidiaries comply with a leverage ratio not to exceed 60% and an interest coverage ratio of more than 1.5:1 on all outstanding debt, after giving effect to the incurrence of the debt. The indenture also restricts the ability of the Company and its subsidiaries to incur secured debt unless the Company and its consolidated subsidiaries comply with a secured debt leverage ratio not to exceed 40% after giving effect to the incurrence of the debt. The indenture also contains other financial and customary covenants, including a covenant not to own unencumbered assets with a value less than 150% of the unsecured indebtedness of the Company and its consolidated subsidiaries. The Company was in compliance with all of the financial covenants under the 2026 Senior Notes as of March 31, 2017.

On July 21, 2016, the Company entered into a $200 million term note maturing July 21, 2028 bearing interest at a fixed rate of 3.67%. The proceeds from this term note were used to repay a portion of the then outstanding balance on the Company’s line of credit.

On April 8, 2014, the Company entered into a $175 million term note maturing April 8, 2024 bearing interest at a fixed rate of 4.533%. The interest rate on the term note increases to 6.283% if the Company is not rated by at least one rating agency or if the Company’s credit rating is downgraded.

In 2011, the Company entered into a $100 million term note maturing August 5, 2021 bearing interest at a fixed rate of 5.54%. The interest rate on the term note increases to 7.29% if the notes are not rated by at least one rating agency, the credit rating on the notes is downgraded or if the Company’s credit rating is downgraded.

The Company had maintained a $150 million unsecured term note maturing April 26, 2016 bearing interest at 6.38%. The Company used a draw on the line of credit to pay off the balance of this note on April 26, 2016.

The line of credit and term notes require the Company to meet certain financial covenants, measured on a quarterly basis, including prescribed leverage, fixed charge coverage, minimum net worth, limitations on additional indebtedness and limitations on dividend payouts. The Company was in compliance with its debt covenants at March 31, 2017.

We believe that if operating results remain consistent with historical levels and levels of other debt and liabilities remain consistent with amounts outstanding at March 31, 2017, the entire availability on the line of credit could be drawn without violating our debt covenants.

The Company’s fixed rate term notes contain a provision that allows for the noteholders to call the debt upon a change of control of the Company at an amount that includes a make whole premium based on rates in effect on the date of the change of control. At this time no change in control is planned or anticipated.

Deferred debt issuance costs and the discount on the 2026 Senior Notes are both presented as reductions of term notes in the accompanying consolidated balance sheets at March 31, 2017 and December 31, 2016. Amortization expense related to deferred debt issuance costs was $0.5 million and $0.4 million for the three months ended March 31, 2017 and 2016, respectively, and is included in interest expense in the consolidated statements of income.

The table below summarizes the Company’s debt obligations and interest rate derivatives at March 31, 2017. The estimated fair value of financial instruments is subjective in nature and is dependent on a number of important assumptions, including discount rates and relevant comparable market information associated with each financial instrument. The fair value of the fixed rate term notes and mortgage notes were estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. These assumptions are considered Level 2 inputs within the fair value hierarchy as described in Note 8. The carrying values of our variable rate debt instruments approximate their fair values as these debt instruments bear interest at current market rates that approximate market participant rates. This is considered a Level 2 input within the fair value hierarchy. The use of different market assumptions and estimation methodologies may have a material effect on the reported estimated fair value amounts. Accordingly, the estimates presented below are not necessarily indicative of the amounts the Company would realize in a current market exchange.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

7. DERIVATIVE FINANCIAL INSTRUMENTS

Interest rate swaps are used to adjust the proportion of total debt that is subject to variable interest rates. The interest rate swaps require the Company to pay an amount equal to a specific fixed rate of interest times a notional principal amount and to receive in return an amount equal to a variable rate of interest times the same notional amount. The notional amounts are not exchanged. Forward starting interest rate swaps are also used by the Company to hedge the risk of changes in the interest-related cash outflows associated with the potential issuance of long-term debt. No other cash payments are made unless the contract is terminated prior to its maturity, in which case the contract would likely be settled for an amount equal to its fair value. The Company enters into interest rate swaps with a number of major financial institutions to minimize counterparty credit risk.

The interest rate swaps qualify and are designated as hedges of the amount of future cash flows related to interest payments on variable rate debt. Therefore, the interest rate swaps are recorded in the consolidated balance sheet at fair value and the related gains or losses are deferred in shareholders’ equity or partners’ capital as Accumulated Other Comprehensive Loss (“AOCL”). These deferred gains and losses are recognized in interest expense during the period or periods in which the related interest payments affect earnings. However, to the extent that the interest rate swaps are not perfectly effective in offsetting the change in value of the interest payments being hedged, the ineffective portion of these contracts is recognized in earnings immediately. Ineffectiveness was de minimis for the three months ended March 31, 2017 and 2016.

The Company has interest rate swap agreements in effect at March 31, 2017 as detailed below to effectively convert a total of $325 million of variable-rate debt to fixed-rate debt.

Notional Amount	Effective Date		Expiration Date		Fixed Rate Paid			Floating Rate Received
$125 Million		9/1/2011		8/1/18		2.3700	%		1 month LIBOR
$100 Million		12/30/11		12/29/17		1.6125	%		1 month LIBOR
$100 Million		9/4/13		9/4/18		1.3710	%		1 month LIBOR
$100 Million		12/29/17		11/29/19		3.9680	%		1 month LIBOR
$125 Million		8/1/18		6/1/20		4.1930	%		1 month LIBOR

In the fourth quarter of 2015, the Company entered into forward starting interest rate swap agreements with a total notional value of $50 million. In the first quarter of 2016, the Company entered into additional forward starting interest rate swap agreements with a total notional value of $100 million. These forward starting interest rate swap agreements were entered into to hedge the risk of changes in the interest-related cash flows associated with the potential issuance of fixed rate long-term debt. In conjunction with the issuance of the $600 million 2026 Senior Notes (see Note 5) in the second quarter of 2016, the Company settled the forward starting swap agreements for a loss of approximately $9.2 million. The loss was recorded as accumulated other comprehensive loss and is being amortized as additional interest expense over the ten-year term of the $600 million 2026 Senior Notes. Consistent with the Company’s accounting policy, the cash outflow related to the settlement of the forward starting swap agreements is reflected as a financing activity in the consolidated statements of cash flows.

The interest rate swap agreements are the only derivative instruments, as defined by FASB ASC Topic 815 “Derivatives and Hedging”, held by the Company. During the three months ended March 31, 2017 and 2016, the net reclassification from AOCL to interest expense was $0.9 million and $1.2 million, respectively, based on payments made under the swap agreements. Based on current interest rates, the Company estimates that payments under the interest rate swaps will be approximately $4.0 million for the 12 months ended March 31, 2018. Payments made under the interest rate swap agreements will be reclassified to interest expense as settlements occur or as payments under the 2026 Senior Notes are made. The fair value of the swap agreements, including accrued interest, was a liability of $11.6 million and $13.0 million at March 31, 2017 and December 31, 2016, respectively.

The Company’s agreements with its interest rate swap counterparties contain provisions pursuant to which the Company could be declared in default of its derivative obligations if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender. The interest rate swap agreements also incorporate other loan covenants of the Company. Failure to comply with the loan covenant provisions would result in the Company being in default on the interest rate swap agreements. As of March 31, 2017, the Company had not posted any collateral related to the interest rate swap agreements. If the Company had breached any of these provisions as of March 31, 2017, it could have been required to settle its obligations under the agreements at their net termination cost of $11.6 million.

The changes in AOCL for the three months ended March 31, 2017 and March 31, 2016 are summarized as follows:

(dollars in thousands)	Three Months Ended Mar. 31, 2017			Three Months Ended Mar. 31, 2016

Fair Value Disclosures [Abstract]

Fair Value Measurements

8. FAIR VALUE MEASUREMENTS

The Company applies the provisions of ASC Topic 820 “Fair Value Measurements and Disclosures” in determining the fair value of its financial and nonfinancial assets and liabilities. ASC Topic 820 establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration. Level 3 inputs are unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

Refer to Note 6 for presentation of the fair values of debt obligations which are disclosed at fair value on a recurring basis.

The following table provides the liabilities carried at fair value measured on a recurring basis as of March 31, 2017 and December 31, 2016 (in thousands):

	Asset (Liability)			Level 1		Level 2			Level 3
March 31, 2017
Interest rate swaps	$	(11,585	)		—	$	(11,585	)		—
December 31, 2016
Interest rate swaps	$	(13,015	)		—	$	(13,015	)		—

Interest rate swaps are over the counter securities with no quoted readily available Level 1 inputs, and therefore are measured at fair value using inputs that are directly observable in active markets and are classified within Level 2 of the valuation hierarchy, using the income approach.

During 2017, assets and liabilities measured at fair value on a non-recurring basis included the assets acquired and liabilities assumed in connection with the acquisition of one storage facility (see note 4). To determine the fair value of land, the Company used prices per acre derived from observed transactions involving comparable land in similar locations, which is considered a Level 2 input. To determine the fair value of buildings, equipment and improvements, the Company used current replacement cost based on information derived from construction industry data by geographic region which is considered a Level 2 input. The replacement cost is then adjusted for the age, condition, and economic obsolescence associated with these assets, which are considered Level 3 inputs. The fair value of in-place customer leases is based on the rent lost due to the amount of time required to replace existing customers and the cost to replace in-place tenants which are based on the Company’s historical experience with turnover at its facilities and on market rental rates and estimated downtime required to replace the in-place leases, all of which are Level 3 inputs. The average downtime is based upon estimated demand information including the number of potential customers exhibited in historical property interest data. Other assets acquired and liabilities assumed in the acquisitions consist primarily of prepaid or accrued real estate taxes and deferred revenues from advance monthly rentals paid by customers. The fair values of these assets and liabilities are based on their carrying values as they typically turn over within one year from the acquisition date and these are Level 3 inputs.

9. INVESTMENT IN JOINT VENTURES

The Company has a 20% ownership interest in Sovran HHF Storage Holdings LLC (“Sovran HHF”), a joint venture that owns 39 self-storage properties that are managed by the Company. During the three months ended March 31, 2017, the Company contributed $3.2 million in cash to the joint venture as its share of capital required to fund the repayment of certain mortgages held by the joint venture. The carrying value of the Company’s investment at March 31, 2017 and December 31, 2016 was $46.8 million and $43.8 million, respectively.

Accounting Changes and Error Corrections [Abstract]

Recent Accounting Pronouncements

14. RECENT ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires an entity to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company has the option to apply the provisions of ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying the new guidance recognized at the date of initial application. We are currently evaluating the alternative methods of adoption and the effect of adopting ASU 2014-09 on our financial statements and related disclosures. We are also in the process of assessing which of our operating revenue streams will be impacted by the adoption of the new standard. Leases are specifically excluded from the scope of ASU 2014-09, therefore the Company does not anticipate that adoption of the new standard will have any impact on the timing or amounts of the Company’s rental revenue from customers which is a substantial portion of the Company’s total operating revenues. The Company intends to make a decision on which method of adoption will be elected by the end of the second quarter of 2017.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. This guidance revises existing practice related to accounting for leases under Accounting Standards Codification Topic 840 Leases (ASC 840) for both lessees and lessors. The new guidance in ASU 2016-02 requires lessees to recognize a right-of-use asset and a lease liability for virtually all of their leases (other than leases that meet the definition of a short-term lease). The lease liability will be equal to the present value of lease payments and the right-of-use asset will be based on the lease liability, subject to adjustment such as for initial direct costs. For income statement purposes, the new standard retains a dual model similar to ASC 840, requiring leases to be classified as either operating or finance. For lessees, operating leases will result in straight-line expense (similar to current accounting by lessees for operating leases under ASC 840) while finance leases will result in a front-loaded expense pattern (similar to current accounting by lessees for capital leases under ASC 840). While the new standard maintains similar accounting for lessors as under ASC 840, the new standard reflects updates to, among other things, align with certain changes to the lessee model. ASU 2016-02 is effective for fiscal years and interim periods, within those years, beginning after December 15, 2018. Early adoption is permitted for all entities. The Company has not yet completed its assessment of the impact that the adoption of ASU 2016-02 will have on its consolidated financial statements.

In March 2016, the FASB issued ASU 2016-06, “Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments”. ASU 2016-06 simplifies the embedded derivative analysis for debt instruments containing contingent call or put options by removing the requirement to assess whether a contingent event is related to interest rates or credit risks. ASU 2016-06 is effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2016. The implementation of this update did not result in any changes to our consolidated financial statements.

In March 2016, the FASB issued ASU 2016-07, “Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting”. ASU 2016-07 eliminates the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an adjustment must be made to the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. ASU 2016-07 is effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2016. The implementation of this update did not result in any changes to our consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting” as part of its simplification initiative, which involves several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2016. The implementation of this update did not result in any changes to our consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a Consensus of the Emerging Issues Task Force)” in an effort to reduce existing diversity in practice related to the classification of certain cash receipts and cash payments on the statements of cash flows. The guidance addresses the classification of cash flows related to, among other things, distributions received from equity method investees. The amendments in this update are effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. ASU 2016-15 is not expected to have a material impact on the Company’s consolidated financial statements.

In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash (a Consensus of the Emerging Issues Task Force)” which requires restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this update are effective for annual periods beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption of this update is permitted. Other than modifications to the statement of cash flows, the adoption of ASU 2016-18 is not expected to have a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business” which is intended to assist entities with evaluating whether a set of transferred assets and activities is a business. The amendments in this update are effective for annual periods beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption of this update is permitted and the Company adopted this update effective January 1, 2017. The adoption of ASU 2017-01 is expected to have potential impact on the accounting treatment of properties acquired subsequent to the adoption date. Property acquisitions treated as business combinations under current guidance may no longer be treated as business combinations subsequent to the adoption of ASU 2017-01. To the extent that properties that we acquire do not meet the definition of a “business” under ASU 2017-01, future acquisitions of properties may be accounted for as asset acquisitions resulting in the capitalization of acquisition costs incurred in connection with these transactions and the allocation of the purchase price and related acquisition costs to the assets acquired based on their relative fair values. There were no properties acquired in the first quarter of 2017 that would have been accounted for as business combinations prior to the adoption of ASU 2017-01.

In February 2017, the FASB issued ASU 2017-05, “Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets” which clarifies the scope and application of ASC 610-20 on the sale or transfer of nonfinancial assets, including real estate, and in substance nonfinancial assets to noncustomers, including partial sales. The amendments in this update are effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The Company has not yet completed its assessment of the impact that the adoption of ASU 2017-05 will have on its consolidated financial statements.

15. COMMITMENT AND CONTINGENCIES

At March 31, 2017, the Company was under contract to acquire three self-storage facilities for an aggregate purchase price of approximately $37.6 million. The purchase of these facilities is subject to customary conditions to closing, and there is no assurance that these facilities will be acquired. On April 3, 2017, the Company entered into a three year lease for one of these self-storage facilities, effectively cancelling the purchase contract for this facility which would have included consideration of $14.1 million. Annual minimum lease payments under this lease total $0.6 million.

At March 31, 2017, 191 III was under contract to purchase three self-storage facilities for an aggregate purchase price of $59.2 million, of which the Company is committed to contribute a total of $11.8 million. The purchase of these facilities by 191 III is subject to customary conditions to closing, and there is no assurance that these facilities will be acquired.

On or about August 25, 2014, a putative class action was filed against the Company in the Superior Court of New Jersey Law Division Burlington County. The action seeks to obtain declaratory, injunctive and monetary relief for a class of consumers based upon alleged violations by the Company of the New Jersey Truth in Customer Contract, Warranty and Notice Act, the New Jersey Consumer Fraud Act and the New Jersey Insurance Producer Licensing Act. On October 17, 2014, the action was removed from the Superior Court of New Jersey Law Division Burlington County to the United States District Court for the District of New Jersey. The Company brought a motion to partially dismiss the complaint for failure to state a claim, and on July 16, 2015, the Company’s motion was granted in part and denied in part. On October 20, 2016, the complaint was amended to add a claim that the Company’s insurance program violates New Jersey consumer protection laws. The Company intends to vigorously defend the action, and the possibility of any adverse outcome cannot be determined at this time.

The amendments in this update are effective for annual periods beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption of this update is permitted and the Company adopted this update effective January 1, 2017. The adoption of ASU 2017-01 is expected to have potential impact on the accounting treatment of properties acquired subsequent to the adoption date. Property acquisitions treated as business combinations under current guidance may no longer be treated as business combinations subsequent to the adoption of ASU 2017-01. To the extent that properties that we acquire do not meet the definition of a “business” under ASU 2017-01, future acquisitions of properties may be accounted for as asset acquisitions resulting in the capitalization of acquisition costs incurred in connection with these transactions and the allocation of the purchase price and related acquisition costs to the assets acquired based on their relative fair values. There were no properties acquired in the first quarter of 2017 that would have been accounted for as business combinations prior to the adoption of ASU 2017-01.
