NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2017

1. Organization and description of business

PS Business Parks, Inc. (“PSB”) was incorporated in the state of California in 1990. As of June 30, 2017, PSB owned 78.0% of the common partnership units (the “common partnership units”) of PS Business Parks, L.P. (the “Operating Partnership”). The remaining common partnership units are owned by Public Storage (“PS”). PSB, as the sole general partner of the Operating Partnership, has full, exclusive and complete responsibility and discretion in managing and controlling the Operating Partnership. PSB and its subsidiaries, including the Operating Partnership, are collectively referred to as the “Company.” Assuming issuance of the Company’s common stock upon redemption of its common partnership units, PS would own 41.9% (or 14.5 million shares) of the outstanding shares of the Company’s common stock.

The Company is a fully-integrated, self-advised and self-managed real estate investment trust (“REIT”) that owns, operates, acquires and develops commercial properties, primarily multi-tenant flex, office and industrial space. As of June 30, 2017, the Company owned and operated 28.0 million rentable square feet of commercial space in six states. The Company also manages 684,000 rentable square feet on behalf of PS.

References to the number of properties or square footage are unaudited and outside the scope of the Company’s independent registered public accounting firm’s review of the Company’s financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States).

2. Summary of significant accounting policies

Basis of presentation

The accompanying unaudited consolidated financial statements include the accounts of PSB and the Operating Partnership. All significant inter-company balances and transactions have been eliminated in the consolidated financial statements. The financial statements are presented on an accrual basis in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2017 are not necessarily indicative of the results that may be expected for the year ended December 31, 2017. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.

Consolidation and Equity Method of Accounting

The Company accounts for its investment in a joint venture that it has significant influence over, but does not control, using the equity method of accounting eliminating intra-entity profits and losses as if the joint venture were a consolidated subsidiary.

The Company consolidates all variable interest entities (each a “VIE”) for which it is the primary beneficiary. Generally, a VIE is a legal entity in which the equity investors do not have the characteristics of a controlling financial interest or the equity investors lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support. A limited partnership may be considered a VIE if the limited partners do not participate in operating decisions. Under this criteria, the Operating Partnership is considered a VIE. The Company’s significant asset is its investment in the Operating Partnership, and consequently, substantially all of the Company’s assets and liabilities represent those assets and liabilities of the Operating Partnership. All of the Company’s debt is an obligation

Table of Contents

of the Operating Partnership.

The Company accounts for its investment in a joint venture that the Company does not consolidate but has significant influence over using the equity method of accounting. The joint venture is referred to as “Investment in and advances to unconsolidated joint venture”. At the end of each reporting period, the Company determines the amount of net income or loss based upon the Company’s ownership interest in the joint venture and presents the amount on its consolidated statements of income with a corresponding adjustment to its equity investment carrying amount.

Noncontrolling interests

The Company’s noncontrolling interests are reported as a component of equity separate from the parent’s equity. Purchases or sales of equity interests that do not result in a change in control are accounted for as equity transactions. In addition, net income attributable to the noncontrolling interests is included in net income on the face of the income statement and, upon a gain or loss of control, the interests purchased or sold, as well as any interests retained, are recorded at fair value with any gain or loss recognized in earnings. At the end of each reporting period, the Company determines the amount of equity (book value of net assets) which is allocable to the noncontrolling interests based upon the ownership interest, and an adjustment is made to the noncontrolling interests, with a corresponding adjustment to paid-in capital, to reflect the noncontrolling interests’ equity interest in the Company.

Use of estimates

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates.

Allowance for doubtful accounts

The Company monitors the collectability of its receivable balances including the deferred rent receivable on an ongoing basis. Based on these reviews, the Company maintains an allowance for doubtful accounts for estimated losses resulting from the possible inability of tenants to make contractual rent payments to the Company. A provision for doubtful accounts is recorded during each period. The allowance for doubtful accounts is netted against tenant and other receivables on the consolidated balance sheets. Tenant receivables are net of an allowance for uncollectible accounts totaling $400,000 at June 30, 2017 and December 31, 2016. Deferred rent receivable is net of an allowance for uncollectible accounts totaling $839,000 and $916,000 at June 30, 2017 and December 31, 2016, respectively.

Financial instruments

The methods and assumptions used to estimate the fair value of financial instruments are described below. The Company has estimated the fair value of financial instruments using available market information and appropriate valuation methodologies. Considerable judgment is required in interpreting market data to develop estimates of market value. Accordingly, estimated fair values are not necessarily indicative of the amounts that could be realized in current market exchanges. The Company determines the estimated fair value of financial assets and liabilities utilizing a hierarchy of valuation techniques based on whether the inputs to a fair value measurement are considered to be observable or unobservable in a marketplace. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect market assumptions. This hierarchy requires the use of observable market data when available. The following is the fair value hierarchy:

Level 1—quoted prices for identical instruments in active markets;

Level 2—quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and

Table of Contents

Level 3—fair value measurements derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

Financial assets that are exposed to credit risk consist primarily of cash and cash equivalents and receivables. The Company considers all highly liquid investments with a remaining maturity of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents, which consist primarily of money market investments, are only invested in entities with an investment grade rating. Receivables are comprised of balances due from a large number of customers. Balances that the Company expects to become uncollectible are reserved for or written off. Due to the short period to maturity of the Company’s cash and cash equivalents, accounts receivable, other assets and accrued and other liabilities, the carrying values as presented on the consolidated balance sheets are reasonable estimates of fair value.

Carrying values of the Company’s unsecured Credit Facility (as defined on page 15) approximate fair value. The characteristics of these financial instruments, market data and other comparative metrics utilized in determining these fair values are “Level 2” inputs.

Real estate facilities

Real estate facilities are recorded at cost. Costs related to the renovation or improvement of the properties are capitalized. Expenditures for repairs and maintenance are expensed as incurred. Expenditures that are expected to benefit a period greater than two years and exceed $2,000 are capitalized and depreciated over their estimated useful life. Buildings and improvements are depreciated using the straight-line method over their estimated useful lives, which generally range from five to 30 years. Transaction costs, which include tenant improvements and lease commissions, of $1,000 or more for leases with terms greater than one year are capitalized and depreciated over their estimated useful lives. Transaction costs less than $1,000 or for leases of one year or less are expensed as incurred.

Land and building held for development

Property taxes, insurance, interest and costs essential to the development of property for its intended use are capitalized during the period of development. Upon classification of an asset as held for development, depreciation of the asset is ceased.

Properties held for disposition

An asset is classified as an asset held for disposition when it meets certain requirements, which include, among other criteria, the approval of the sale of the asset, the marketing of the asset for sale and the expectation by the Company that the sale will likely occur within the next 12 months. Upon classification of an asset as held for disposition, depreciation of the asset is ceased, and the net book value of the asset is included on the balance sheet as properties held for disposition.

Intangible assets/liabilities

Intangible assets and liabilities include above-market and below-market in-place lease values of acquired properties based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease. The capitalized above-market and below-market lease values (included in other assets and accrued liabilities in the accompanying consolidated balance sheets) are amortized to rental income over the remaining non-cancelable terms of the respective leases.

As of June 30, 2017, the value of in-place leases resulted in net intangible assets of $889,000, net of $9.4 million of accumulated amortization with a weighted average amortization period of 9.6 years, and net intangible liabilities

Table of Contents

of $525,000, net of $10.3 million of accumulated amortization with a weighted average amortization period of 7.3 years. As of December 31, 2016, the value of in-place leases resulted in net intangible assets of $1.1 million, net of $9.2 million of accumulated amortization and net intangible liabilities of $784,000, net of $10.0 million of accumulated amortization.

The Company recorded net increases in rental income of $9,000 and $138,000 for the three months ended June 30, 2017 and 2016, respectively, and $34,000 and $331,000 for the six months ended June 30, 2017 and 2016, respectively, due to the amortization of net intangible liabilities resulting from the above-market and below-market lease values.

Evaluation of asset impairment

The Company evaluates its assets used in operations for impairment by identifying indicators of impairment and by comparing the sum of the estimated undiscounted future cash flows for each asset to the asset’s carrying value. When indicators of impairment are present and the sum of the estimated undiscounted future cash flows is less than the carrying value of such asset, an impairment loss is recorded equal to the difference between the asset’s current carrying value and its value based on discounting its estimated future cash flows. In addition, the Company evaluates its assets held for disposition for impairment. Assets held for disposition are reported at the lower of their carrying value or fair value, less cost of disposition. At June 30, 2017, the Company did not consider any assets to be impaired.

Stock compensation

All share-based payments to employees, including grants of employee stock options, are recognized as stock compensation in the Company’s income statement based on their grant date fair values. See Note 11.

Revenue and expense recognition

The Company must meet four basic criteria before revenue can be recognized: persuasive evidence of an arrangement exists; the delivery has occurred or services have been rendered; the fee is fixed or determinable; and collectability is reasonably assured. All leases are classified as operating leases. Rental income is recognized on a straight-line basis over the terms of the leases. Straight-line rent is recognized for all tenants with contractual fixed increases in rent that are not included on the Company’s credit watch list. Deferred rent receivable represents rental revenue recognized on a straight-line basis in excess of billed rents. Reimbursements from tenants for real estate taxes and other recoverable operating expenses are recognized as rental income in the period the applicable costs are incurred. Property management fees are recognized in the period earned.

Costs incurred in connection with leasing (primarily tenant improvements and lease commissions) are capitalized and amortized over the lease period.

Gains from sales of real estate facilities

The Company recognizes gains from sales of real estate facilities at the time of sale using the full accrual method, provided that various criteria related to the terms of the transactions and any subsequent involvement by the Company with the properties sold are met. If the criteria are not met, the Company defers the gains and recognizes them when the criteria are met or uses the installment or cost recovery methods as appropriate under the circumstances.

General and administrative expenses

General and administrative expenses include executive and other compensation, office expenses, professional fees, acquisition transaction costs, state income taxes and other such administrative items.

Table of Contents

Income taxes

The Company has qualified and intends to continue to qualify as a REIT, as defined in Section 856 of the Internal Revenue Code of 1986, as amended. As a REIT, the Company is not subject to federal income tax to the extent that it distributes its REIT taxable income to its shareholders. A REIT must distribute at least 90% of its REIT taxable income each year. In addition, REITs are subject to a number of organizational and operating requirements. The Company may be subject to certain state and local taxes on its income and property and to federal income and excise taxes on its undistributed taxable income. The Company believes it met all organization and operating requirements to maintain its REIT status during 2016 and intends to continue to meet such requirements for 2017. Accordingly, no provision for income taxes has been made in the accompanying consolidated financial statements.

The Company can recognize a tax benefit only if it is “more likely than not” that a particular tax position will be sustained upon examination or audit. To the extent that the “more likely than not” standard has been satisfied, the benefit associated with a position is measured as the largest amount that is greater than 50% likely of being recognized upon settlement. As of June 30, 2017, the Company did not recognize any tax benefit for uncertain tax positions.

Accounting for preferred equity issuance costs

The Company records issuance costs as a reduction to paid-in capital on its balance sheet at the time the preferred securities are issued and reflects the carrying value of the preferred equity at the stated value. Such issuance costs are recorded as non-cash preferred equity distributions at the time the Company notifies the holders of preferred stock of its intent to redeem such shares.

Net income per common share

Per share amounts are computed using the number of weighted average common shares outstanding. “Diluted” weighted average common shares outstanding includes the dilutive effect of stock options and restricted stock units under the treasury stock method. “Basic” weighted average common shares outstanding excludes such effect. The Company's restricted stock units are participating securities and are included in the computation of basic and diluted weighted average common shares outstanding. The Company’s restricted stock unit holders are paid non-forfeitable dividends in excess of the expense recorded which results in a reduction in net income allocable to common shareholders and unit holders.

Earnings per share has been calculated as follows (in thousands, except per share amounts):



	For The Three Months				For The Six Months
	Ended June 30,				Ended June 30,
	2017		2016		2017		2016
Net income allocable to common shareholders	$	24,742	$	15,731	$	51,135	$	30,300
Weighted average common shares outstanding:
Basic weighted average common shares outstanding		27,200		27,082		27,174		27,063
Net effect of dilutive stock compensation—based on
treasury stock method using average market price		212		90		210		86
Diluted weighted average common shares outstanding		27,412		27,172		27,384		27,149
Net income per common share—Basic	$	0.91	$	0.58	$	1.88	$	1.12
Net income per common share—Diluted	$	0.90	$	0.58	$	1.87	$	1.12

No options were excluded from the computation of diluted net income per share for the three months ended June 30, 2017 and 2016 as no options were considered anti-dilutive. Options to purchase 16,000 and 14,000 shares for the six months ended June 30, 2017 and 2016, respectively, were not included in the computation of diluted net income per share because such options were considered anti-dilutive.

The Company views its operations as one segment.

Reclassifications

Certain reclassifications have been made to the consolidated financial statements for 2016 in order to conform to the 2017 presentation.

Recently issued accounting standards

In May, 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, which amended the existing accounting standards for revenue recognition. The core principle underlying this guidance is that entities will recognize revenue upon the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled for such exchange. The guidance also provides a model for the measurement and recognition of gains and losses on the sale of certain nonfinancial assets, such as property and equipment, including real estate. This guidance is currently effective for the Company’s fiscal year beginning January 1, 2018. Early adoption is permitted for the Company’s fiscal year beginning January 1, 2017. ASU 2014-09 allows for full retrospective adoption applied to all periods presented or modified retrospective adoption with the cumulative effect of initially applying the standard recognized at the date of initial application. The Company intends to adopt the guidance using the modified retrospective approach for the fiscal year beginning January 1, 2018. The Company anticipates no impact upon adoption of the new accounting guidance on its consolidated financial statements relating to the Company’s facility management fees for property management services provided to PS or the recognition of gains and losses on the sale of real estate assets as the Company’s current accounting for such transactions is consistent with the new guidance’s core principle. Rental income from leasing arrangements are a substantial portion of the Company’s revenue and is specifically excluded from ASU 2014-09 and will be governed by the applicable lease codification (ASU 2016-02, Leases). In conjunction with the adoption of the leasing guidance, the Company is currently in the process of evaluating certain variable payment terms included in these lease arrangements which are governed by ASU 2014-09.

In February, 2016, the FASB issued ASU 2016-02, Leases, which amends the existing accounting standards for lease accounting. The guidance requires lessees to classify leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. The classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and related liability for most leases with a term of greater than 12 months, regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The new guidance is expected to result in the recognition of a right-of-use asset and related liability to account for the Company’s future obligations under the ground lease arrangements for which the Company is the lessee. As of June 30, 2017, the remaining contractual payments under the ground lease agreements aggregated $315,000. For leases in which the Company is the lessor, the lease contract will be separated into lease and non-lease components in accordance with the provisions outlined within ASU No. 2014-09. The lease component of the contract will be recognized on a straight-line basis in accordance with ASU 2016-02, while the non-lease component will be recognized under the provisions of ASU 2014-09. Additionally, the new guidance will require that lessees and lessors capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. This guidance is effective for annual periods beginning after December 15, 2018 and interim periods within annual periods beginning after December 15, 2018. Early adoption is permitted. The guidance must be adopted using a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. The Company is currently in the process of evaluating the impact of adoption of the new accounting guidance on its consolidated financial statements.

In August, 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments,

Table of Contents

which provides guidance on the classification of certain specific cash receipts and cash payments in the statement of cash flows, including, but not limited to, cash distributions received from equity method investees, including unconsolidated joint ventures. The new standard is effective for periods beginning after December 15, 2017, with early adoption permitted and shall be applied retrospectively where practicable. The Company is currently in the process of evaluating the impact of adoption of the new accounting guidance on its consolidated financial statements.

In November, 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230) – Restricted Cash, which requires the consolidated statements of cash flows to explain the change during the period in the total cash, cash equivalents, restricted cash and restricted cash equivalents. The new guidance also requires entities to reconcile such total to amounts on the balance sheet and disclose the nature of the restrictions. The guidance is effective for public entities for fiscal years beginning after December 15, 2017 and for interim periods therein, with early adoption permitted. The guidance must be adopted using a modified retrospective approach. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements.

In January, 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805) - Clarifying the Definition of a Business, which provides guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions of assets or businesses. Under the new guidance, a set of transferred assets and activities is not a business when substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. If a set of transferred assets and activities does not meet this threshold, then an entity must evaluate whether the set meets the requirement that a business include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. The new standard is effective for public entities for fiscal years beginning after December 15, 2017 and for interim periods therein. Early adoption is permitted. The guidance will be applied prospectively to any transactions occurring within the period of adoption. The Company adopted the guidance effective January 1, 2017 and expects the guidance will likely result in future acquisitions of operating properties being accounted for as asset acquisitions instead of business combinations with transaction costs of such acquisitions to be capitalized as part of the purchase price of the acquisition. Prior to the adoption of the new guidance, the Company accounted for acquisitions of operating properties as business combinations and expensed transaction costs as acquisition-related expenses.

3. Real estate facilities

The activity in real estate facilities for the six months ended June 30, 2017 is as follows (in thousands):



			Buildings and		Accumulated
	Land		Improvements		Depreciation		Total
Balances at December 31, 2016	$	789,227	$	2,224,522	$	(1,158,054)	$	1,855,695
Capital expenditures		—		23,751		—		23,751
Disposals		—		(6,715)		6,715		—
Depreciation and amortization		—		—		(46,706)		(46,706)
Transfer to property held for disposition		—		—		25		25
Balances at June 30, 2017	$	789,227	$	2,241,558	$	(1,198,020)	$	1,832,765

The purchase price of acquired properties is recorded to land, buildings and improvements (including tenant improvements, unamortized lease commissions, acquired in-place lease values, and tenant relationships, if any) and intangible assets and liabilities associated with the value of above-market and below-market leases based on their respective estimated fair values. Acquisition-related costs are expensed as incurred.

In determining the fair value of the tangible assets of the acquired properties, management considers the value of the properties as if vacant as of the acquisition date. Management must make significant assumptions in determining the value of assets acquired and liabilities assumed. Using different assumptions in the recording of the purchase cost of the acquired properties would affect the timing of recognition of the related revenue and expenses. Amounts recorded to land are derived from comparable sales of land within the same region. Amounts recorded to buildings

Table of Contents

and improvements, tenant improvements and unamortized lease commissions are based on current market replacement costs and other market information. The amount recorded to acquired in-place leases is determined based on management’s assessment of current market conditions and the estimated lease-up periods for the respective spaces.

The Company did not acquire any assets or assume any liabilities during the six months ended June 30, 2017 and 2016.

On May 1, 2017, the Company disposed of Empire Commerce, a two-building single-story office park comprising 44,000 square feet, located in Dallas, Texas, for net proceeds of $2.1 million, which resulted in a net gain of $1.2 million.

On March 31, 2017, the Company sold development rights it held to build medical office buildings on land adjacent to its Westech Business Park in Silver Spring, Maryland for $6.5 million. The Company had acquired the development rights as part of its 2006 acquisition of the park. The Company has received $4.0 million of proceeds, of which $1.5 million was received in prior years and $2.5 million was received in March, 2017. The Company recorded a gain of $3.9 million related to the proceeds received through June 30, 2017 less transaction costs of $135,000 as these amounts are non-refundable. The Company will report an additional gain of $2.5 million when the final proceeds are received in the fourth quarter of 2017 and the remaining contingencies have lapsed.

4. Investment in and advances to unconsolidated joint venture

In 2013, the Company entered into a joint venture known as Amherst JV LLC (the “Joint Venture”) with an unrelated real estate development company (the “JV Partner”) for the purpose of developing a 395-unit multi-family building on a five-acre site (the “Project”) within the Company’s 628,000 square foot office park located in Tysons, Virginia (known as “The Mile”). PSB holds a 95.0% interest in the Joint Venture with the remaining 5.0% held by the JV Partner. The JV Partner is responsible for the development and construction of the Project and through an affiliate will oversee the leasing and management of the Project. The JV partner serves as the managing member, with mutual consent from both the Company and the managing member required for all significant decisions. As such, the Company accounts for its investment in the Joint Venture using the equity method.

On October 5, 2015 (the “Contribution Date”), the Company contributed the site, along with capitalized improvements, to the Joint Venture. The Company has agreed to provide the Joint Venture with a construction loan in the amount of $75.0 million. The Joint Venture will pay interest under the construction loan at a rate equal to the London Interbank Offered Rate (“LIBOR”) plus 2.25%. The loan will mature on April 5, 2019 with two one-year extension options.

The aggregate amount of development costs are estimated to be $105.6 million (excluding unrealized land appreciation). The Company is committed to funding $75.0 million through the construction loan in addition to its equity contribution of $28.5 million, which includes a land basis of $15.3 million. The Project delivered its first completed units in May, 2017, with final completion date expected during the fourth quarter of 2017.

The Company has reflected the aggregate value of the contributed site, its’ equity contributions, capitalized interest and loan advances to date as investment in and advances to unconsolidated joint venture. The Company’s investment in and advances to unconsolidated joint venture was $91.3 million and $67.2 million as of June 30, 2017 and December 31, 2016, respectively. For the six months ended June 30, 2017, the Company made loan advances of $23.9 million and capitalized $506,000 of interest. For the six months ended June 30, 2016, the Company made loan advances to the Joint Venture of $6.8 million, equity contributions of $5.7 million and capitalized $739,000 of interest.

The Joint Venture commenced its operations during the second quarter of 2017 as 233 of the 395 units were delivered. During the three and six months ended June 30, 2017, the Company recorded an equity loss in the unconsolidated joint venture of $382,000, comprised of a net operating loss of $278,000 and depreciation expense of $104,000.

5. Leasing activity

The Company leases space in its real estate facilities to tenants primarily under non-cancelable leases generally ranging from one to 10 years. Future minimum rental revenues, excluding recovery of operating expenses under these leases, are as follows as of June 30, 2017 (in thousands):



Remainder of 2017	$	146,944
2018		249,289
2019		177,053
2020		117,279
2021		80,550
Thereafter		136,783
Total	$	907,898

In addition to minimum rental payments, certain tenants reimburse the Company for their pro rata share of specified operating expenses. Such reimbursements amounted to $22.7 million and $20.5 million for the three months ended June 30, 2017 and 2016, respectively, and $45.9 million and $41.3 million for the six months ended June 30, 2017 and 2016, respectively. These amounts are included as rental income in the accompanying consolidated statements of income.

Leases accounting for 3.2% of total leased square footage are subject to termination options, of which 1.4% of total leased square footage have termination options exercisable through December 31, 2017. In general, these leases provide for termination payments should the termination options be exercised. The future minimum rental revenues in the above table assume such options are not exercised.

6. Bank loans

In January, 2017, the Company modified and extended the terms of its line of credit (the “Credit Facility”) and the Company’s related guaranty with Wells Fargo Bank, National Association (“Wells Fargo”). The Credit Facility has a borrowing limit of $250.0 million and expires January 10, 2022. The rate of interest charged on borrowings is based on the LIBOR plus 0.80% to LIBOR plus 1.55% depending on the Company’s credit ratings. Currently, the Company’s rate under the Credit Facility is LIBOR plus 0.825%. In addition, the Company is required to pay an annual facility fee ranging from 0.10% to 0.30% of the borrowing limit depending on the Company’s credit ratings (currently 0.125%). In connection with the extension, the Company paid $613,000 of loan origination costs. As of June 30, 2017, the Company had $101.0 million outstanding on the Credit Facility at an interest rate of 1.81%. Subsequent to June 30, 2017, the Company repaid net $14.0 million on the Credit Facility. The Company had no balance outstanding on the Credit Facility at December 31, 2016. The Company had $1.0 million and $539,000 of unamortized loan origination costs as of June 30, 2017 and December 31, 2016, respectively, which is included in other assets in the accompanying consolidated balance sheets. The Credit Facility requires the Company to meet certain covenants, all of which the Company was in compliance with as of June 30, 2017. Interest on outstanding borrowings is payable monthly.

7. Noncontrolling interests

As described in Note 2, the Company reports noncontrolling interests within equity in the consolidated financial statements, but separate from the Company’s shareholders’ equity. In addition, net income allocable to noncontrolling interests is shown as a reduction from net income in calculating net income allocable to common shareholders.

Common partnership units

The Company presents the accounts of PSB and the Operating Partnership on a consolidated basis. Ownership interests in the Operating Partnership that can be redeemed for common stock, other than PSB’s interest, are classified

Table of Contents

as noncontrolling interests—common units in the consolidated financial statements. Net income allocable to noncontrolling interests—common units consists of the common units’ share of the consolidated operating results after allocation to preferred units and shares. Beginning one year from the date of admission as a limited partner (common units) and subject to certain limitations described below, each limited partner other than PSB has the right to require the redemption of its partnership interest.

A limited partner (common units) that exercises its redemption right will receive cash from the Operating Partnership in an amount equal to the market value (as defined in the Operating Partnership Agreement) of the partnership interests redeemed. In lieu of the Operating Partnership redeeming the common units for cash, PSB, as general partner, has the right to elect to acquire the partnership interest directly from a limited partner exercising its redemption right, in exchange for cash in the amount specified above or by issuance of one share of PSB common stock for each unit of limited partnership interest redeemed.

A limited partner (common units) cannot exercise its redemption right if delivery of shares of PSB common stock would be prohibited under the applicable articles of incorporation, or if the general partner believes that there is a risk that delivery of shares of common stock would cause the general partner to no longer qualify as a REIT, would cause a violation of the applicable securities laws, or would result in the Operating Partnership no longer being treated as a partnership for federal income tax purposes.

At June 30, 2017, there were 7,305,355 common units owned by PS, which are accounted for as noncontrolling interests. Combined with PS’s existing common stock ownership, on a fully converted basis, PS has a combined ownership of 41.9% (or 14.5 million shares) of the Company’s common equity.

11. Stock compensation

PSB has a 2003 Stock Option and Incentive Plan (the “2003 Plan”) and a 2012 Equity and Performance-Based Incentive Compensation Plan (the “2012 Plan”) covering 1.5 million and 1.0 million shares of PSB’s common stock, respectively. Under the 2003 Plan and 2012 Plan, PSB has granted non-qualified options to certain directors, officers and key employees to purchase shares of PSB’s common stock at a price not less than the fair market value of the common stock at the date of grant. Additionally, under the 2003 Plan and 2012 Plan, PSB has granted restricted shares of common stock to certain directors and restricted stock units to officers and key employees.

The weighted average grant date fair value of options granted during the six months ended June 30, 2017 and 2016 was $14.42 per share and $8.41 per share, respectively. The Company has calculated the fair value to each option grant on the date of grand using the Black Scholes option-pricing model with the following weighted average assumptions used for grants during the six months ended June 30, 2017 and 2016, respectively: a dividend yield of 2.8% and 3.1%; expected volatility of 17.5% and 15.2%; expected life of five years; and risk-free interest rates of 1.9% and 1.4%.

The weighted average grant date fair value of restricted stock units granted during the six months ended June 30, 2017 and 2016 was $89.25 and $83.59, respectively. The Company calculated the fair value of each restricted stock unit grant using the market value on the date of grant.

At June 30, 2017, there was a combined total of 1.0 million options and restricted stock units authorized to be granted.

Effective March, 2014, the Company entered into a performance-based restricted stock unit program, the Senior Management Long-Term Equity Incentive Program for 2014-2017 (“LTEIP”), with certain employees of the Company. Under the LTEIP, the Company established three levels of targeted restricted stock unit awards for certain employees, which would be earned only if the Company achieved one of three defined targets during 2014 to 2017. Under the LTEIP there is an annual award following the end of each of the four years in the program, with the award subject to and based on the achievement of total return targets during the previous year, as well as an award based on achieving total return targets during the cumulative four-year period 2014-2017. In the event the minimum defined target is not achieved for an annual award, the restricted stock units allocated to be awarded for such year are added to the restricted stock units that may be received if the four-year target is achieved. All restricted stock unit awards under the LTEIP vest in four equal annual installments beginning from the date of award. Up to 100,150 restricted stock units would be awarded for each of the four years assuming achievement was met and up to 91,800 restricted stock units would be awarded for the cumulative four-year period assuming achievement was met. Compensation expense is recognized based on the restricted stock units expected to be awarded based on the target level that is expected to be achieved. Net compensation expense of $1.1 million and $4.1 million related to the LTEIP was recognized for the three months ended June 30, 2017 and 2016, respectively, and $2.9 million and $6.6 million for the six months ended June 30, 2017 and 2016, respectively. Included in the 2016 amount, the Company recorded a net non-cash stock compensation charge of $2.0 million related to a change in senior management and the future issuance of restricted stock units our former Chief Executive Officer will receive under the Company’s LTEIP.

In connection with the LTEIP, targets for 2016 were achieved at the highest threshold total return level. As such, 100,150 restricted stock units were granted during the six months ended June 30, 2017 at a weighted average grant date fair value of $88.91.

Included in the Company’s consolidated statements of income for the three months ended June 30, 2017 and 2016, was $54,000 and $46,000, respectively, in net compensation expense related to stock options. Net compensation expense of $103,000 and $178,000 related to stock options was recognized during the six months ended June 30, 2017 and 2016, respectively. Net compensation expense of $1.4 million and $4.1 million related to restricted stock units was recognized during the three months ended June 30, 2017 and 2016, respectively. Net compensation expense of $3.4 million and $6.7 million related to restricted stock units was recognized during the six months ended June 30,

Table of Contents

2017 and 2016, respectively.

As of June 30, 2017, there was $657,000 of unamortized compensation expense related to stock options expected to be recognized over a weighted average period of 3.8 years. As of June 30, 2017, there was $10.3 million of unamortized compensation expense related to restricted stock units expected to be recognized over a weighted average period of 3.3 years.

Cash received from 37,256 stock options exercised during the six months ended June 30, 2017 was $2.2 million. Cash received from 16,823 stock options exercised during the six months ended June 30, 2016 was $900,000. The aggregate intrinsic value of the stock options exercised was $2.4 million and $723,000 during the six months ended June 30, 2017 and 2016, respectively.

During the six months ended June 30, 2017, 68,914 restricted stock units vested; in settlement of these units, 38,627 shares were issued, net of 30,287 shares applied to payroll taxes. The aggregate fair value of the shares vested for the six months ended June 30, 2017 was $7.7 million. During the six months ended June 30, 2016, 43,689 restricted stock units vested; in settlement of these units, 25,604 shares were issued, net of 18,085 shares applied to payroll taxes. The aggregate fair value of the shares vested for the six months ended June 30, 2016 was $4.2 million. In addition to the vesting of these shares, tax deposits totaling $3.4 million and $1.8 million were made during the six months ended June 30, 2017 and 2016, respectively, on behalf of employees in exchange for common shares withheld upon vesting.

In April, 2015, the shareholders of the Company approved the issuance of up to 130,000 shares of common stock under the Retirement Plan for Non-Employee Directors (the “Director Plan”). Under the Director Plan, the Company grants 1,000 shares of common stock for each year served as a director up to a maximum of 8,000 shares issued upon retirement. The Company recognizes compensation expense over the requisite service period. As a result, included in the Company’s consolidated statements of income was $71,000 and $85,000 in compensation expense for the three months ended June 30, 2017 and 2016, respectively, and $148,000 and $169,000 for the six months ended June 30, 2017 and 2016, respectively.

Overview

As of June 30, 2017, the Company owned and operated 28.0 million rentable square feet of multi-tenant flex, industrial and office properties concentrated primarily in six states.

The Company focuses on increasing profitability and cash flow aimed at maximizing shareholder value. The Company strives to maintain high occupancy levels while increasing rental rates and minimizing capital expenditures when market conditions allow, although the Company may decrease rental rates in markets where conditions require. The Company also acquires properties it believes will create long-term value, and from time to time disposes of properties which no longer fit within the Company’s strategic objectives. Operating results are driven primarily by income from rental operations and are therefore substantially influenced by demand for rental space within our properties and our markets, which impacts occupancy, rental rates and capital requirements.

Critical Accounting Policies and Estimates: Our accounting policies are described in Note 2 to the consolidated financial statements included in this Quarterly Report on Form 10-Q. We believe our most critical accounting policies relate to revenue recognition, property acquisitions, allowance for doubtful accounts, impairment of long-lived assets, depreciation, accruals of operating expenses and accruals for contingencies, each of which are more fully described in “Part I, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our annual report on Form 10-K for the year ended December 31, 2016.

Effect of Acquisitions, Development and Dispositions of Properties on the Company’s Operations: The Company is focused on growing its operations by looking for opportunities to expand its presence in existing and new markets through strategic acquisitions that meet the Company’s focus on multi-tenant flex, industrial and office parks in markets where it has or may obtain a substantial market presence. The Company may also from time to time dispose of assets based on market conditions.

Acquisitions: On September 28, 2016, the Company acquired two multi-tenant office buildings, which comprise the 226,000 square feet of Non-Same Park portfolio (defined below), in Rockville, Maryland, for a purchase price of $13.3 million. As of June 30, 2017, the occupancy rate of this asset increased to 22.5% since the date of acquisition. The Company had 175,000 square feet of vacant space spread within the acquired buildings as of June 30, 2017. The

Table of Contents

buildings are located within Shady Grove Executive Park, where the Company owns three other buildings aggregating 352,000 square feet, which were 94.2% leased as of June 30, 2017.

Development: As of November 1, 2016, the Company transferred a 123,000 square foot building located within The Mile in Tysons, Virginia to land and building held for development, as the Company is pursuing entitlements to develop an additional multi-family complex on this site. The scope and timing of any future development will be subject to a variety of approvals and contingencies. Prior to being classified as land and building held for development, the building was occupied by a single user. The net operating income (“NOI”) associated with the prior tenant is reflected as NOI from asset held for development.

Highgate Multi- Family Joint Venture: In 2013, the Company entered into a joint venture known as Amherst JV LLC (the “Joint Venture”) with an unrelated real estate development company (the “JV Partner”) for the purpose of developing a 395-unit multi-family building on a five-acre site within The Mile in Tysons, Virginia (the “Project”). PSB holds a 95.0% interest in the Joint Venture with the remaining 5.0% held by the JV Partner. The JV Partner is responsible for the development and construction of the Project and through an affiliate will oversee the leasing and management of the Project. The JV partner serves as the managing member, with mutual consent from both the Company and the managing member required for all significant decisions. As such, the Company accounts for its investment in the Joint Venture using the equity method.

The Project delivered its first completed units in May, 2017, with final completion expected during the fourth quarter of 2017. The following table summarizes the Joint Venture’s Project timeline and updates as of June 30, 2017:

The Project cost for the Joint Venture reflects the underlying land at the assigned contribution value upon formation of the Joint Venture. The estimated total costs of the Project includes land basis of $15.3 million plus unrealized land appreciation of $11.6 million.

⁽²⁾

As of July 24, 2017, Highgate’s multi-family residential units were 19.0% leased and 14.2% occupied.

⁽³⁾

Average monthly rental rate is defined as the total potential monthly rental revenue (actual rent for occupied apartment homes plus market rent for vacant apartment homes) dividend by the number of apartment homes.

In addition to its equity contribution of $28.5 million, which includes land basis of $15.3 million, the Company has agreed to provide the Joint Venture with a construction loan in the amount of $75.0 million. The Joint Venture will pay interest under the construction loan at a rate equal to the London Interbank Offered Rate (“LIBOR”) plus 2.25%. The loan will mature on April 5, 2019 with two one-year extension options. The Joint Venture had an outstanding construction loan balance of $59.0 million as of June 30, 2017. The Company has reflected the aggregate value of the contributed site, its’ equity contributions, capitalized interest and loan advances to date as investment in and advances to unconsolidated joint venture.

The Company’s investment in and advances to unconsolidated joint venture was $91.3 million and $67.2 million at June 30, 2017 and December 31, 2016, respectively. For the six months ended June 30, 2017, the Company made loan advances of $23.9 million (which excludes accrued interest of $764,000) and capitalized $506,000 of interest.

Dispositions: On May 1, 2017, the Company disposed of Empire Commerce, a two-building single-story office park comprising 44,000 square feet, located in Dallas, Texas, for net proceeds of $2.1 million, which resulted in a net gain of $1.2 million.

Table of Contents

rights as part of its 2006 acquisition of the park. The Company has received $4.0 million of proceeds, of which $1.5 million was received in prior years and $2.5 million was received in March, 2017. The Company recorded a gain of $3.9 million related to the proceeds received through June 30, 2017 less transaction costs of $135,000 as these amounts are non-refundable. The Company will report an additional gain of $2.5 million when the final proceeds are received in the fourth quarter of 2017 and the remaining contingencies have lapsed.

Impact of Inflation: Although inflation has not been significant in recent years, it remains a potential factor in our economy, and the Company continues to seek ways to mitigate its potential impact. A substantial portion of the Company’s leases require tenants to pay operating expenses, including real estate taxes, utilities, and insurance, as well as increases in common area expenses, partially reducing the Company’s exposure to inflation.

Key Operating Metrics

The Company’s operations are substantially concentrated in eight regions. Each of the eight regions in which the Company owns assets is subject to its own unique market influences. All operating metrics discussed in this section as of and for the three and six months ended June 30, 2017 and 2016 exclude assets sold or held for development. Management believes excluding the results of such assets provides the most relevant perspective on the ongoing operations of the Company. Please refer to “Part I, Item 1. Financial Statements” included in this Quarterly Report on Form 10-Q for financial metrics that include results from assets sold or held for development.

Net Operating Income: Rental income, cost of operations and rental income less cost of operations, excluding depreciation and amortization, or NOI, are summarized for the three and six months ended June 30, 2017 and 2016. NOI is a non-GAAP financial measure that is often used by investors to determine the performance and value of commercial real estate. Depreciation and amortization have been excluded from NOI as they are generally not used in determining the value of commercial real estate by management or the investment community. Depreciation and amortization are generally not used in determining value as they consider the historical costs of an asset compared to its current value; therefore, to understand the effect of the assets’ historical cost on the Company’s results, investors should look at GAAP financial measures, such as total operating costs including depreciation and amortization. The Company’s calculation of NOI may not be comparable to those of other companies and should not be used as an alternative to measures of performance calculated in accordance with GAAP. As part of the tables below, we have reconciled total NOI to net income, which we consider the most directly comparable financial measure calculated in accordance with GAAP.

To present comparative results, for the purpose of computing NOI, the tables below exclude amortization of the Senior Management Long-Term Equity Incentive Plan (“LTEIP”) for the three and six months ended June 30, 2017 and 2016.

Concentration of Portfolio by Region: The table below reflects the Company’s square footage based on regional concentration as of June 30, 2017. As part of the table below, we have reconciled total NOI to net income (in thousands):

Rental rate change is computed by taking the percentage difference between outgoing rents and incoming rents for leases executed during the period. Leases executed on spaces vacant for more than the preceding twelve months have been excluded.

During the first six months of 2017, most markets continued to reflect favorable conditions allowing for stable occupancy as well as increasing rental rates. With the exception of the Virginia and Maryland markets, new rental rates for the Company improved over expiring rental rates on executed leases as economic conditions and tenant demand remained healthy. The Virginia and Maryland markets continue to experience soft market conditions as evidenced by continued pressure on occupancy and rental rates. Given lease expirations of 1.3 million square feet in Virginia and 802,000 square feet in Maryland through December 31, 2018, the Company may continue to experience a decrease in rental income in these markets.

Comparative Analysis of the Three and Six Months Ended June 30, 2017 to the Three and Six Months Ended June 30, 2016

Results of Operations: In order to evaluate the performance of the Company’s portfolio over comparable periods, management analyzes the operating performance of properties owned and operated throughout both periods (herein referred to as “Same Park”). The Same Park portfolio includes all operating properties acquired prior to January 1, 2015. Operating properties acquired subsequently are referred to as “Non-Same Park.” For the three and six months ended June 30, 2017 and 2016, the Same Park facilities constitute 27.8 million rentable square feet, representing 99.3% of the 28.0 million square feet in the Company’s total portfolio as of June 30, 2017.

The following table presents the operating results of the Company’s properties for the three and six months ended June 30, 2017 and 2016 in addition to other income and expenses items affecting net income. For comparative purposes, the Company adjusts certain items from rental income, cost of operations and general and administrative expenses (in thousands, except per square foot data):

Rental Income:

Rental income increased $3.7 million, or 3.9%, from $96.1 million for the three months ended June 30, 2016 to $99.8 million for the three months ended June 30, 2017.

Rental income increased $7.9 million, or 4.1%, from $191.9 million for the six months ended June 30, 2016 to $199.9 million for the six months ended June 30, 2017.

The three and six month increases in adjusted rental income from the Same Park portfolio of $4.3 million, or 4.5%, and $9.0 million, or 4.8%, respectively, was due to higher executed rental rates and an increase in occupancy.

The three and six month increases in adjusted rental income from the Non-Same Park facilities of $314,000 and $605,000, respectively, was resulting from an asset acquisition during the third quarter of 2016.

Total cost of operations	$	30,250	$	29,750	1.7%	$	61,283	$	61,644	(0.6%)

The three month increase in adjusted cost of operations from the Same Park portfolio of $821,000, or 2.9%, was due to increases in compensation expense and utility costs as well as higher property taxes in Virginia and Southern Texas.

Table of Contents

The six month decrease in adjusted cost of operations from the Same Park portfolio of $117,000, or 0.2%, was due to lower repairs and maintenance costs due to a mild snow season in 2017 partially offset by increases in compensation expense and property taxes.

The three and six month increases in adjusted cost of operations from the Non-Same Park facilities of $270,000 and $624,000, respectively, was resulting from an asset acquisition during the third quarter of 2016.

Depreciation and Amortization Expense: Depreciation and amortization expense was $23.6 million for the three months ended June 30, 2017 compared to $25.2 million for the same period in 2016. Depreciation and amortization expense was $46.7 million for the six months ended June 30, 2017 compared to $50.3 million for the same period in 2016. The three and six month decreases in depreciation and amortization expense was due to assets being fully depreciated.

General and Administrative Expenses:

For the three and six months ended June 30, 2017, general and administrative expenses decreased $2.9 million, or 54.6%, and $3.7 million, or 41.5%, respectively, compared to the same periods in 2016 primarily due to a change in senior management in July, 2016.

The three and six month decreases in adjusted general and administrative expenses of $352,000, or 16.9%, and $525,000, or 12.8%, respectively, were driven by lower compensation expense. The six month decrease was also due to accelerated stock compensation related to a director retiring in 2016.

Equity loss from investment in and advances to unconsolidated joint venture: At June 30, 2017, the Company holds a 95.0% equity investment in the Joint Venture. The Company accounts for such investment using the equity method and records its pro-rata share of the net loss in the Joint Venture for each period. The Joint Venture commenced its operations during the second quarter of 2017. During the three and six months ended June 30, 2017, the Company recorded an equity loss in the unconsolidated joint venture of $382,000, comprised of a net operating loss of $278,000 and depreciation expense of $104,000. The equity loss from the Joint Venture was a result of a physical occupancy rate of 9.1% at June 30, 2017.

Net Income Allocable to Noncontrolling Interests: Net income allocable to noncontrolling interests reflects the net income allocable to equity interests in PS Business Parks, L.P. (the “Operating Partnership”) that are not owned by the Company. Net income allocable to noncontrolling interests was $6.6 million and $4.2 million for the three months ended June 30, 2017 and 2016, respectively, and $13.7 million and $8.2 million for the six months ended June 30, 2017 and 2016, respectively. The three month increase was due to an increase in overall NOI, reduced interest expense resulting from the repayment of a $250.0 million mortgage note and a gain on sale of real estate facility in Dallas, Texas. The six month increase was also impacted by the gain on sale of development rights in Silver Spring, Maryland.

Tenant Credit Risk: The Company historically has experienced a low level of write-offs of uncollectable rents, but there is inherent uncertainty in a tenant’s ability to continue paying rent and meet its full lease obligation. The table below summarizes the impact to the Company from tenants’ inability to pay rent or continue to meet their lease obligations (in thousands):

As of July 24, 2017, the Company had 69,000 square feet of leased space occupied by four tenants that are protected by Chapter 11 of the U.S. Bankruptcy Code. From time to time, tenants contact us, requesting early termination of their lease, reductions in space under lease, or rent deferment or abatement. At this time, the Company cannot anticipate what impact, if any, the ultimate outcome of these discussions will have on our future operating results.

Liquidity and Capital Resources

Cash and cash equivalents decreased $123.2 million from $128.6 million at December 31, 2016 to $5.4 million at June 30, 2017 for the reasons noted below.

Net cash provided by operating activities for the six months ended June 30, 2017 and 2016 was $137.5 million and $118.8 million, respectively. The increase of $18.7 million in net cash provided by operating activities was primarily due to an increase in NOI combined with a reduction in interest paid tied to the repayment of a $250.0 million mortgage note in June, 2016. Management believes that the Company’s internally generated net cash provided by operating activities will be sufficient to enable it to meet its operating expenses, capital expenditures, debt service requirements and distributions to shareholders for the foreseeable future.

Net cash used in investing activities was $44.9 million and $27.7 million for the six months ended June 30, 2017 and 2016, respectively. The change was due to an increase in cash investment in the Joint Venture combined with an increase in cash paid related to capital improvements partially offset by proceeds received from the sale of development rights in Silver Spring, Maryland and the sale of a real estate facility in Dallas, Texas.

Net cash used in financing activities was $215.9 million and $276.3 million for the six months ended June 30, 2017 and 2016, respectively. The change was primarily due to repayment of a mortgage note payable of $250.0 million in 2016 compared to funds used to redeem preferred stock of $230.0 million in 2017. The change was also impacted by increased borrowings of $47.0 million from the Credit Facility.

The Company’s preferred equity outstanding decreased from 21.7% of its market capitalization at December 31, 2016 to 15.9% at June 30, 2017 primarily due to a decrease in preferred stock outstanding from $1.1 billion at December 31, 2016 to $879.8 million at June 30, 2017 combined with borrowings of $101.0 million from the Credit Facility in 2017. The Company calculates market capitalization by adding (1) the liquidation preference of the Company’s outstanding preferred equity, (2) principal value of the Company’s outstanding debt and (3) the total number of common shares and common units outstanding multiplied by the closing price of the stock on that date.

The Company focuses on retaining cash for reinvestment, as we believe this provides us the greatest level of financial flexibility. As operating fundamentals improve, additional increases in distributions to the Company’s common shareholders may be required. The Company will continue to monitor its taxable income and the corresponding dividend requirements. During the first quarter of 2017, the Company increased its quarterly dividend from $0.75 per common share to $0.85 per common share.

Redemption of Preferred Stock: On December 7, 2016, the Company called for the redemption of its 6.45% Cumulative Preferred Stock, Series S, at its par value of $230.0 million and subsequently completed the redemption

Table of Contents

on January 18, 2017. The Company reported non-cash distributions of $7.3 million, representing the original issuance costs, as a reduction of net income allocable to common shareholders and unit holders for the year ended December 31, 2016. As of December 31, 2016, the Company reclassified the 6.45% Cumulative Preferred Stock, Series S, of $230.0 million from equity to liabilities as preferred stock called for redemption.

Repurchase of Common Stock: No shares of common stock were repurchased under the board-approved common stock repurchase program during the six months ended June 30, 2017 or the year ended December 31, 2016.

Mortgage Note Repayment: On June 1, 2016, the Company repaid in full a $250.0 million mortgage note which had a fixed interest rate of 5.45%.

Investment in and Advances to Unconsolidated Joint Venture: The aggregate amount of development costs are estimated to be $105.6 million (excluding unrealized land appreciation of $11.6 million). The Company is committed to funding $75.0 million through a construction loan ($59.0 million was outstanding as of June 30, 2017) in addition to its equity contribution of $28.5 million, which includes a land basis of $15.3 million. The Company’s investment in and advances to unconsolidated joint venture was $91.3 million and $67.2 million as of June 30, 2017 and December 31, 2016, respectively. For the six months ended June 30, 2017, the Company made loan advances of $23.9 million and capitalized $506,000 of interest.

For the six months ended June 30, 2016, the Company made loan advances of $6.8 million, equity contributions of $5.7 million and capitalized $739,000 of interest.

Capital Expenditures: The Company defines recurring capital expenditures as those necessary to maintain and operate its commercial real estate at its current economic value. During the six months ended June 30, 2017 and 2016, the Company expended $22.2 million and $14.1 million, respectively, in recurring capital expenditures, or $0.79 and $0.51 per weighted average square foot owned, respectively. Tenant improvements exclude tenant reimbursements of $388,000 and $1.7 million for the six months ended June 30, 2017 and 2016, respectively. Nonrecurring capital improvements include property renovations and expenditures related to repositioning acquisitions.

The following table depicts capital expenditures (in thousands):

Total recurring capital expenditures		0.79		0.51
Nonrecurring capital improvements		0.04		0.01
Total capital expenditures	$	0.83	$	0.52

The increase in recurring capital expenditures of $8.1 million, or 57.3%, was primarily due to large renewals and expansions in the Same Park portfolio during 2017 combined with transaction costs related to the 2016 acquisition.

Distributions: The Company has elected and intends to qualify as a REIT for federal income tax purposes. In order to maintain its status as a REIT the Company must meet certain organizational and operational requirements related to its share ownership, sources of income and asset composition. As a REIT, the Company is not taxed on that portion of its taxable income that is distributed to its shareholders provided it meets annual minimum dividend distribution requirements.

During the first quarter of 2017, the Board of Directors of the Company (the “Board”) increased its quarterly dividend from $0.75 per common share to $0.85 per common share, which is an increase of $0.10 or 13.3% over the previous quarter’s distribution.

The Company paid distributions of $71.4 million ($25.2 million to preferred shareholders and $46.2 million to common shareholders) and $68.3 million ($27.7 million to preferred shareholders and $40.6 million to common shareholders) during the six months ended June 30, 2017 and 2016, respectively. All of these distributions were REIT qualifying distributions.

The Board will continue to evaluate our dividend rate in light of our actual and projected taxable income, liquidity requirements and other circumstances, and there can be no assurance that the future dividends declared by our Board will not differ materially.

The Company’s funding strategy has been to primarily use permanent capital, including common and preferred stock, along with internally generated retained cash flows to meet its liquidity needs. In addition, the Company may sell properties that no longer meet its investment criteria. From time to time, the Company may use its Credit Facility or other forms of debt to facilitate real estate acquisitions or other capital allocations. For the six months ended June 30, 2017, the earnings to combined fixed charges and preferred distributions coverage ratio was 3.4 to 1.0. The Company targets a minimum ratio of FFO (as defined below) to combined fixed charges and preferred distributions of 3.0 to 1.0. Fixed charges include interest expense and capitalized interest while preferred distributions include amounts paid to preferred shareholders and preferred Operating Partnership unit holders. For the six months ended June 30, 2017, the FFO to combined fixed charges and preferred distributions coverage ratio was 5.0 to 1.0.

Non-GAAP Supplemental Disclosure Measure: Funds from Operations: Management believes that Funds from Operations (“FFO”) and FFO, as adjusted are useful supplemental measures of the Company’s operating performance. The Company computes FFO in accordance with the White Paper on FFO approved by the Board of Governors of the National Association of Real Estate Investment Trusts. The White Paper defines FFO as net income, computed in accordance with GAAP, before depreciation, amortization, gains or losses on asset dispositions, net income allocable to noncontrolling interests — common units, net income allocable to restricted stock unit holders, impairment charges and nonrecurring items. Management believes that FFO provides a useful measure of the Company’s operating

Table of Contents

performance and when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, development activities, general and administrative expenses and interest costs, providing a perspective not immediately apparent from net income.

FFO and FFO, as adjusted should be analyzed in conjunction with net income. However, FFO and FFO, as adjusted should not be viewed as substitutes for net income as measures of operating performance or liquidity, as they do not reflect depreciation and amortization costs or the level of capital expenditure and leasing costs necessary to maintain the operating performance of the Company’s properties, which are significant economic costs and could materially affect the Company’s results of operations.

Management believes FFO provides useful information to the investment community about the Company’s operating performance when compared to the performance of other real estate companies as FFO is generally recognized as the industry standard for reporting operations of REITs. Management believes FFO, as adjusted provides useful information to the investment community by adjusting FFO for certain items so as to provide more meaningful period-to-period comparisons of our operating performance. Other REITs may use different methods for calculating FFO and/or FFO, as adjusted and, accordingly, our FFO and FFO, as adjusted may not be comparable to other real estate companies’ FFO and/or FFO, as adjusted.

FFO for the Company is computed as follows (in thousands, except per share data):

FFO allocable to common and dilutive shares, as adjusted, increased $6.8 million and $16.1 million for the three and six months ended June 30, 2017 compared to the same periods in 2016. The three and six month increases were due to an increase in NOI, reduced interest expense and savings from lower preferred distributions.

Related Party Transactions: As of June 30, 2017, PS owned 7.2 million shares of the Company’s common stock and 7.3 million common units of the Operating Partnership (100.0% of the common units not owned by the Company). Assuming issuance of the Company’s common stock upon redemption of its common partnership units, PS would own 41.9% (or 14.5 million shares) of the outstanding shares of the Company’s common stock at June 30, 2017. Ronald L. Havner, Jr., the Company’s chairman, is also the Chairman of the Board, Chief Executive Officer of PS. Joseph D. Russell, Jr. is a director of the Company and also President of PS. Gary E. Pruitt, an independent director of the Company is also a trustee of PS.

Pursuant to a cost sharing and administrative services agreement, the Company shares costs with PS for certain administrative services and rental of corporate office space. The administrative services include investor relations, legal, lease administration, corporate tax and information systems, which were allocated between the Company and PS in accordance with a methodology intended to fairly allocate those costs. Costs allocated to the Company totaled $132,000 and $123,000 for the three months ended June 30, 2017 and 2016, respectively, and $265,000 and $247,000 for the six months ended June 30, 2017 and 2016, respectively. Costs allocated to PS totaled $8,000 and $15,000 for the three and six months ended June 30, 2017, respectively. In addition, the Company provides property management services for properties owned by PS for a management fee equal to 5% of the gross revenues of such properties in addition to reimbursement of certain costs. These management fee revenues recognized under a management contract with PS totaled $124,000 and $131,000 for the three months ended June 30, 2017 and 2016, respectively, and $252,000 and $259,000 for the six months ended June 30, 2017 and 2016, respectively. PS also provides property management services for the self-storage component of two assets owned by the Company for a fee of 6% of the gross revenues of such properties in addition to reimbursement of certain costs. Management fee expense recognized under the management contract with PS totaled $23,000 and $21,000 for the three months ended June 30, 2017 and 2016, respectively, and $45,000 and $42,000 for the six months ended June 30, 2017 and 2016, respectively.

The PS Business Parks name and logo are owned by PS and licensed to the Company under a non-exclusive, royalty-free license agreement. The license can be terminated by either party for any reason with six months written notice.

Off-Balance Sheet Arrangements: The Company does not have any off-balance sheet arrangements that have or are reasonably likely to have a material effect on the Company’s financial condition, results of operations, liquidity, capital expenditures or capital resources.

Contractual Obligations: The Company is scheduled to pay cash dividends of $50.4 million per year on its

Table of Contents

preferred equity outstanding as of June 30, 2017. Dividends are paid when and if declared by the Company’s Board and accumulate if not paid. Shares of preferred equity are redeemable by the Company in order to preserve its status as a REIT and are also redeemable five years after issuance.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

To limit the Company’s exposure to market risk, the Company principally finances its operations and growth with permanent equity capital consisting of either common or preferred stock. As a result, the Company’s debt as a percentage of total equity (based on book values) was 5.6% as of June 30, 2017.

Our exposure to market risk for changes in interest rates relates primarily to the Credit Facility, which is subject to variable interest rates. See Notes 2 and 6 to the consolidated financial statements included in this Quarterly Report on Form 10-Q for additional information regarding the terms, valuations and approximate principal maturities of the Company’s indebtedness, including the Credit Facility. Based on borrowing rates currently available to the Company, the difference between the carrying amount of debt and its fair value is insignificant.

ITEM 4. CONTROLS AND PROCEDURES

The Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of June 30, 2017. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of the Company’s disclosure controls and procedures as of June 30, 2017, the Company’s Chief Executive Officer and Chief Financial Officer concluded that, as of such date, the Company’s disclosure controls and procedures were effective at the reasonable assurance level. The Company also has an investment in an unconsolidated joint venture and because we do not control the joint venture, our disclosure controls and procedures with respect to such joint venture are substantially more limited than those we maintain with respect to our consolidated subsidiaries.

There have not been any changes in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the fiscal quarter ended June 30, 2017 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION
