As of ~~June~~September 30, 2017, PSB owned 78.0% of the common partnership units ~~(the “common partnership units”)~~ of PS Business Parks, L.P. (the ~~“Operating Partnership”~~“OP”). The remaining common partnership units are owned by Public Storage (“PS”). PS’s interest in the OP is referred to as the “PS OP Interest.” PSB, as the sole general partner of the ~~Operating Partnership,~~OP, has full, exclusive and complete responsibility and discretion in managing and controlling the ~~Operating Partnership.~~OP. PSB and its subsidiaries, including the ~~Operating Partnership,~~OP, are collectively referred to as the ~~“Company.~~“Company,” ~~Assuming issuance of the Company’s common stock upon redemption of its common partnership units,~~“we,” “us,” or “our.” PS would own 41.9% (or 14.5 million shares) of the outstanding shares of the Company’s common ~~stock.~~stock if it redeemed its common partnership units for common shares.

Basis of presentation

The accompanying unaudited consolidated financial statements include the accounts of PSB and its subsidiaries, including the ~~Operating Partnership.~~OP. 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~~nine months ended ~~June~~September 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~~We consider entities ~~(each a “VIE”~~to be Variable Interest Entities (“VIEs”) ~~for which it is the primary beneficiary. Generally, a VIE is a legal entity in which the~~when they have insufficient 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~~their activities without additional subordinated financial ~~support.~~support provided by other parties, or the equity holders as a group do not have a controlling financial interest. A limited partnership ~~may be~~is also generally considered a VIE if the limited partners do not participate in operating decisions. ~~Under this criteria,~~We consolidate VIEs when we are the ~~Operating Partnership is considered~~primary beneficiary, generally defined as having (i) the power to direct the activities most significantly impacting economic performance and (ii) either the obligation to absorb losses or the right to receive benefits from the VIE.

We account for investments in entities that are not VIEs that we have significant influence over, but do not control, using the equity method of accounting. At September 30, 2017, we have an interest in a ~~VIE. The Company’s significant asset is its investment~~joint venture engaged in the ~~Operating Partnership,~~development and ~~consequently, substantially all~~operation of residential real estate, which we account for using the ~~Company’s assets and liabilities represent those assets and liabilities~~equity method of ~~the Operating Partnership. All of the Company’s debt is an obligation~~accounting. See Note 4 for more information on this entity.

Table of Contents

PS, the sole limited partner in the OP, has no power to direct the activities of the ~~Operating Partnership.~~

~~The Company accounts for its investment in~~OP. We are the primary beneficiary of the OP. Accordingly, we consider the OP a ~~joint venture that~~VIE and consolidate it. Substantially all of our assets and liabilities are held by 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.OP.

Noncontrolling interests

The ~~Company’s~~PS OP Interest represents PS’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.~~OP through its ownership of 7,305,355 common partnership units.

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 estimated uncollectible accounts totaling $400,000 at ~~June~~September 30, 2017 and December 31, 2016. Deferred rent receivable is net of an allowance for uncollectible accounts totaling ~~$839,000~~$910,000 and $916,000 at ~~June~~September 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.

Table of Contents

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. Property taxes, insurance, interest and costs essential to the development of property for its intended use are capitalized during the period of development. 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.

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.not depreciated.

Intangible assets/liabilities

~~Intangible assets~~When we acquire facilities, an intangible asset is recorded for leases where the in-place rent is higher than market rents, and ~~liabilities include above-market and below-market~~an intangible liability is recorded where the market rents are higher than the in-place ~~lease values of acquired properties~~rents. The amounts recorded are based onupon the present value (using ~~an interest~~a discount rate which reflects the risks associated with the leases acquired) of such differences over the ~~difference between (i) the contractual~~lease term and such 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.

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.

Accrued and other liabilities and other assets

Accrued and other liabilities consist primarily of rents prepaid by our tenants, trade payables, property tax accruals, accrued payroll and contingent loss accruals when probable and estimable. We disclose the nature of significant unaccrued losses that are reasonably possible of occurring and, if estimable, a range of exposure. Other assets are comprised primarily of prepaid expenses. We believe the fair value of our accrued and other liabilities and other assets approximate book value, due to the short period until settlement.

Revenue ~~and expense~~ recognition

~~The Company must meet four basic criteria before revenue can be recognized:~~Revenue is recognized with respect to contractual arrangements when 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~~lease term, with 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 cumulative rental income recognized over the cumulative rent billed ~~rents.~~for the lease term reflected as “deferred rent receivable” on our consolidated balance sheets. 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~~acquiring tenants (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, corporate office expenses, professional fees, acquisition transaction costs, state income taxes and other such ~~administrative items.~~costs that are not directly related to the operation of our real estate facilities.

Income taxes

We have elected to be treated as a REIT, as defined in the Internal Revenue Code of 1986, as amended (the “Code”). As a REIT, we do not incur federal income tax if we distribute 100% of our REIT taxable income each year, and if we meet certain organizational and operational rules. We believe we have met these REIT requirements for all periods presented herein. Accordingly, we have recorded no federal income tax expense related to our REIT taxable income.

We recognize tax benefits of uncertain income tax positions that are subject to audit only if we believe it is more likely than not that the position would ultimately be sustained assuming the relevant taxing authorities had full knowledge of the relevant facts and circumstances of our positions. As of September 30, 2017, we did not recognize any tax benefits for uncertain positions.

Accounting for preferred equity issuance costs

We record issuance costs as a reduction to paid-in capital on our consolidated balance sheets at the time the preferred securities are issued and reflect the carrying value of the preferred equity at its redemption value. An additional allocation of income is made from the common shareholders to the preferred shareholders in the amount of

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~~original issuance costs, ~~as a reduction~~and we reclassify the redemption value from equity to ~~paid-in capital on its balance sheet at the time the~~liabilities when we call 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.shares for redemption.

Net income per common share

~~Per~~Notwithstanding the presentation of income allocations on our consolidated statements of income, net income is allocated to (a) preferred shareholders, for distributions paid, (b) preferred shareholders, to the extent redemption value exceeds the related carrying value (a “Preferred Redemption Allocation”) and (c) restricted share ~~amounts are computed using~~unit holders, for non-forfeitable dividends paid adjusted for participation rights in undistributed earnings. The remaining net income is allocated to the common partnership units and our common shareholders, respectively, based upon the pro-rata aggregate number of ~~weighted average common~~units and 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.

Recently issued accounting standards

In May 2014 and February 2016, the Financial Accounting Standards Board ~~(“FASB”)~~ issued two Accounting Standards ~~Update~~Updates (“ASU”)s), ASU 2014-09, Revenue from Contracts with Customers (the “Revenue Standard”), and ASU 2016-02, Leases (the “Lease Standard”). These standards apply to substantially all of our revenue generating activities, as well as provide a model to account for the disposition of real estate facilities to non-customers, which ~~amended~~is governed under ASU 2017-05.

The Lease Standard will direct how we account for payments from the ~~existing~~elements of our leases that are generally fixed and determinable at the inception of the lease (“Fixed Lease Payments”) while the Revenue Standard will direct how we account for the non-lease components of our lease contracts, primarily expense reimbursements (“Non-Lease Payments”) and the accounting ~~standards~~ for the disposition of real estate facilities.

Under various share-based compensation plans, 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 grantedgrants non-qualified options to purchase the Company’s common shares at a price not less than fair value on the date of grant, as well as restricted stock units (“RSUs”), 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~~service period for stock options and RSUs begins when (i) the Company and the recipient reach a mutual understanding of ~~options granted during~~ the ~~six months ended June 30, 2017~~key terms of the award, (ii) the award has been authorized, (iii) the recipient is affected by changes in the market price of our stock and ~~2016 was $14.42 per share~~(iv) it is probable that any performance conditions will be met, and ~~$8.41 per share, respectively. The Company has calculated~~ends when the ~~fair value to each~~stock 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%.or RSU vests.

~~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~~We amortize the fair value of awards at the beginning of the service period as compensation expense. For awards that are earned solely upon the passage of time and continued service, the entire cost of the award is amortized on a straight-line basis over the service period. For awards with performance conditions, the individual cost of each ~~restricted stock unit~~vesting is amortized separately over each individual service period (the “accelerated attribution” method).

In amortizing share-based compensation expense, we do not estimate future forfeitures in advance. Instead, we reverse previously amortized share-based compensation expense with respect to grants that are forfeited in the period the employee terminates employment.

Stock options vest over a five-year period, expire after the grant ~~using~~date and the ~~market value~~exercise price is equal to the closing trading price of our common shares on the ~~date~~grant date. Employees cannot require the Company to settle their award in cash. We use the Black-Scholes option valuation model to estimate the fair value of ~~grant.~~our stock options.

~~At June~~For the three and nine months ended September 30, 2017, ~~there was a combined total of 1.0 million~~respectively we recorded $53,000 and $156,000 in compensation expense related to stock options, as compared to $51,000 and ~~restricted stock units authorized to be granted.~~$229,000 for the same periods in 2016.

~~Information with respect to~~During the nine months ended September 30, 2017, 16,000 stock options were granted and 69,676 options were exercised. A total of 175,979 options were outstanding ~~options and nonvested restricted stock units granted under the 2003 Plan and 2012 Plan is as follows:~~at September 30, 2017 (229,655 at December 31, 2016).

RSUs generally vest ratably over a five-year period from the grant date. The grantee receives dividends for each outstanding RSU equal to the per-share dividends received by our common shareholders. We expense any dividends previously paid upon forfeiture of the related RSU. Upon vesting, the grantee receives common shares equal to the number of vested RSUs, less common shares withheld in exchange for tax deposits made by the Company to satisfy the grantee’s statutory tax liabilities arising from the vesting. The fair value of our RSUs is determined based upon the applicable closing trading price of our common shares on the date of grant.

For the three and nine months ended September 30, 2017, respectively, we recorded a net reversal of $521,000 and expense of $2.9 million in compensation expense related to RSUs, as compared to expense of $1.7 million and $8.5 million for the same periods in 2016. In conjunction with the departure of our Chief Financial Officer (“CFO”), the Company recorded a reversal of stock compensation of $1.9 million in RSU expense related to RSUs under our LTEIP (see below) during the third quarter of 2017. The 2016 amount includes $2.0 million in additional RSU expense related to RSUs under our LTEIP expected to be issued to our former Chief Executive Officer (“CEO”).

During the nine months ended September 30, 2017, 110,750 RSUs were granted, 15,806 RSUs were forfeited and 76,994 RSUs vested. This vesting resulted in the issuance of 43,223 common shares. In addition, tax deposits totaling $3.9 million ($1.9 million for the same period in 2016) were made on behalf of employees in exchange for 33,771 common shares withheld upon vesting. A total of 162,643 RSUs were outstanding at September 30, 2017 (144,693 at December 31, 2016).

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~~94,150 restricted stock units would be awarded for each of the four years assuming achievement was met and up to ~~91,800~~81,800 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~~The compensation expense ~~of $1.1 million~~ and ~~$4.1 million related~~RSU counts with respect 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,

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.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Forward-Looking Statements: Forward-looking statements, within the meaning of the Private Securities Litigation Reform Act of 1995, are made throughout this Quarterly Report on Form 10-Q. For this purpose, any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. Without limiting the foregoing, the words “may,” “believes,” “anticipates,” “plans,” “expects,” “seeks,” “estimates,” “intends” and similar expressions are intended to identify forward-looking statements. There are a number of important factors that could cause the results of the Company to differ materially from those indicated by such forward-looking statements, including but not limited to: (a) changes in general economic and business conditions; (b) decreases in rental rates or increases in vacancy rates/failure to renew or replace expiring leases; (c) tenant defaults; (d) the effect of the recent credit and financial market conditions; (e) our failure to maintain our status as a ~~real estate investment trust (“REIT”)~~REIT under the Internal Revenue Code of 1986, as amended; (f) the economic health of our tenants; (g) increases in operating costs; (h) casualties to our properties not covered by insurance; (i) the availability and cost of capital; (j) increases in interest rates and its effect on our stock price; and (k) other factors discussed under the heading “Part I, Item 1A. Risk Factors” in our annual report on Form 10-K for the year ended December 31, 2016. In light of the significant uncertainties inherent in the forward-looking statements included herein, the inclusion of such information should not be regarded as a representation by us or any other person that our objectives and plans will be achieved. Moreover, we assume no obligation to update these forward-looking statements to reflect actual results, changes in assumptions or changes in other factors affecting such forward-looking statements, except as required by law.

Our accounting policies are described in Note 2 to the consolidated financial statements included in this Form 10-Q. We believe the following are our critical accounting policies, because they have a material impact on the portrayal of our financial condition and results, and they require us to make judgments and estimates about matters that are inherently uncertain.

Income Tax Expense: We have elected to be treated as a REIT, as defined in the Internal Revenue Code of 1986, as amended (the “Code”). As a REIT, we do not incur federal income tax on our REIT taxable income that is fully distributed each year (for this purpose, certain distributions paid in a subsequent year may be considered), and if we meet certain organizational and operational rules. We believe we have met these REIT requirements for all periods presented herein. Accordingly, we have recorded no federal income tax expense related to our REIT taxable income.

Our evaluation that we have met the REIT requirements could be incorrect, because compliance with the tax rules requires factual determinations, and circumstances we have not identified could result in noncompliance with the tax requirements in current or prior years. For any taxable year that we fail to qualify as a REIT and for which applicable statutory relief provisions did not apply, we would be taxed at the regular corporate rates on all of our taxable income for at least that year and the ensuing four years, we could be subject to penalties and interest, and our net income would be materially different from the amounts estimated in our consolidated financial statements.

Accounting for Acquired Real Estate Facilities: We estimate the fair values of the land, buildings, intangible assets and intangible liabilities for purposes of allocating the purchase price. Such estimates are based upon many assumptions and judgments, including (i) market rates of return and capitalization rates on real estate and intangible assets, (ii) building and material cost levels, (iii) comparisons of the acquired underlying land parcels to recent land transactions, (iv) estimated market rent levels and (v) future cash flows from the real estate and the existing tenant base. Others could come to materially different conclusions as to the estimated fair values, which would result in different depreciation and amortization expense, rental income, gains and losses on sale of real estate assets, and real estate and intangible assets.

Allowance for Doubtful Accounts: Tenant receivables consist primarily of amounts due for contractual lease payments, reimbursements of common area maintenance expenses, property taxes and other expenses recoverable from tenants. Deferred rent receivable represents the amount that the cumulative straight-line rental income recorded to date exceeds cash rents billed to date under the lease agreement. Determination of the adequacy of allowances for doubtful accounts requires significant judgments and estimates. Others could come to materially different conclusions regarding the adequacy of our allowance for doubtful accounts. Significant unreserved bad debt losses could materially impact our net income.

Impairment of Long-Lived Assets: The analysis of impairment of our long-lived assets involves identification of indicators of impairment, projections of future operating cash flows and estimates of fair values or selling prices, all of which require significant judgment and subjectivity. Others could come to materially different conclusions. In addition, we may not have identified all current facts and circumstances that may affect impairment. Any unidentified impairment loss, or change in conclusions, could have a material adverse impact on our net income.

Accrual for Uncertain and Contingent Liabilities: We accrue for certain contingent and other liabilities that have significant uncertain elements, such as property taxes, performance bonuses and other operating expenses, as well as other legal claims and disputes involving customers, employees, governmental agencies and other third parties. We estimate such liabilities based upon many factors such as assumptions of past and future trends and our evaluation of likely outcomes. However, the estimates of known liabilities could be incorrect or we may not be aware of all such liabilities, in which case our accrued liabilities and net income could be misstated.

AsOur overall operating results are impacted primarily by the performance of ~~June~~our existing real estate facilities, which at September 30, 2017 ~~the Company owned and operated~~are comprised of 28.0 million rentable square feet of multi-tenant flex, industrial and office properties concentrated ~~primarily~~ in six ~~states.~~states and a 95.0% interest in 395 apartments. Accordingly, a significant degree of management attention is paid to maximizing the cash flow from our existing real estate portfolio. We also acquire properties we believe will create long-term value, and from time to time we dispose of properties which no longer fit within the Company’s strategic objectives.

Existing Real Estate Facilities:The ~~Company focuses on increasing profitability~~operating results of our existing real estate facilities are substantially influenced by demand for rental space within our properties and ~~cash flow aimed at maximizing shareholder value. The Company strives~~our markets, which impacts occupancy, rental rates and capital requirements. We strive 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,~~Management’s initiatives and ~~from time~~strategies with respect to ~~time disposes of properties~~our existing real estate facilities 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”~~detail in our ~~annual report on~~December 31, 2016 Form 10-K, include incentivizing our personnel to maximize the return on investment for ~~the year ended December 31, 2016.~~ each lease transaction and providing a superior level of service to our customers.

~~Acquisitions:~~ ~~On September 28,~~ 2016, ~~the Company~~we acquired two multi-tenant office buildings ~~which comprise the~~aggregating 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~~The occupancy rate ~~of this asset~~has increased ~~to 22.5% since~~from 18.5% on the date of ~~acquisition.~~acquisition to 31.6% as of September 30, 2017. These buildings are located within The ~~Company had 175,000~~Grove 270 (formerly Shady Grove Executive Park) where we already owned three substantially fully-leased buildings aggregating 352,000 square feet. We continue to seek to acquire additional facilities in our existing markets and generally in proximity to our existing facilities; however, there can be no assurance that we will acquire additional facilities that meet our risk-adjusted return and underwriting requirements.

Development or redevelopment of real estate facilities: We also may seek to redevelop our existing real estate. We own a large contiguous block of real estate (628,000 rentable square feet on 44.5 acres of ~~vacant space spread~~land) located within The Mile in Tysons, Virginia. We demolished one of our existing office buildings in The Mile and are building a multi-family building (the “Highgate Development”), with completion in stages starting in May, 2017 through the ~~acquired buildings as of June 30, 2017. The~~fourth

~~buildings are located within Shady Grove Executive Park, where~~quarter of 2017. The total estimated investment upon completion, including the ~~Company owns three other buildings aggregating 352,000 square feet, which were 94.2% leased as~~fair value of ~~June 30, 2017.~~existing land, will be approximately $117.2 million.

~~Development:~~ AsWhile multi-family real estate is not a core asset for us, we determined that multi-family real estate represented a unique opportunity and the highest and best use of ~~November 1, 2016,~~this parcel. We have partnered through a joint venture with a local developer and operator of multi-family space in order to leverage their operational experience. See “Analysis of Items Not Included in Operating Income – Equity in loss of unconsolidated joint venture” below and Note 4 to our consolidated financial statements for more information on the ~~Company transferred a~~Highgate Development.

We do not consolidate the joint venture that holds the Highgate Development; accordingly, our share of net loss is reflected under “equity in loss of unconsolidated joint venture.”

We have an additional 123,000 square foot office building located within The Mile that we are seeking to demolish in ~~Tysons, Virginia~~order to ~~land and building held for development, as the Company is pursuing entitlements to develop an additional~~construct another multi-family complex on ~~this site.

~~Highgate Multi- Family Joint Venture:~~Dispositions of Real Estate Facilities: In ~~2013, the Company entered into~~2014, we completed a ~~joint venture known as Amherst JV LLC (the “Joint Venture”) with an unrelated~~plan to exit non-strategic markets in Sacramento California, Oregon and Arizona. We do not expect to exit any additional markets. However, we may from time to time dispose of individual real estate ~~development company (the “JV Partner”) for the purpose of developing a 395-unit multi-family building~~assets based on ~~a five-acre site within The Mile in Tysons, Virginia (the “Project”). PSB holds a 95.0% interest in the Joint Venture~~market conditions, fit 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:

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:~~our existing portfolio or other reasons. On May 1, 2017, ~~the Company~~we 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.

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.~~Certain Factors that May Impact Future Results

Impact of Inflation: Although inflation has not been significant in recent years, ~~it remains a potential factor~~an increase in inflation could impact our ~~economy,~~future results, 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.~~inflation during each lease’s respective lease period.

~~Key~~Regional Concentration: Our portfolio is concentrated in eight regions, in six states. We have chosen to concentrate in these regions because we believe they have characteristics which enable them to be competitive economically, such as above average population growth, job growth, higher education levels and personal income, which we believe will produce better overall economic returns. Changes in economic conditions in these regions in the future could impact our future results.

Industry and Tenant Concentrations: We seek to minimize the risk of industry or tenant concentrations. As of September 30, 2017, leases from our top 10 tenants comprised 10.3% of our annualized rental income, with only two tenants, Kaiser Permanente (1.0%) and the U.S. Government (4.3%), representing more than 1%. In terms of industry concentration, 18.5% of our annualized rental income comes from Business Services; 10.4% from Warehouse, Distribution, Transportation and Logistics; and 10% from Health Services. No other industry group represents more than 10% of our annualized rental income.

Tenant credit risk: We have historically experienced a low level of write-offs of uncollectible rents, with less than 0.5% of rental income written off each year over the last six years. However, there can be no assurance that write offs may not increase, because there is inherent uncertainty in a tenant’s ability to continue paying rent and meet its full lease obligation. As of October 23, 2017, we 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 leased, or rent deferment or abatement.

We evaluate the performance of our business parks primarily based on Net Operating Income (“NOI”), a non-GAAP financial measure, because we believe NOI is an important measure of the value and performance of our real estate. We believe investors utilize NOI in a similar manner and for similar reasons. NOI is defined by the Company as Adjusted Rental Income less Adjusted Cost of Operations (described below) and excludes depreciation and amortization. Depreciation and amortization is excluded from NOI because management and investors do not consider it important in valuing real estate or evaluating real estate performance, because depreciation assumes the value of real estate declines ratably from its historical cost based upon the passage of time, while we believe the value of real estate changes based upon cash flow and other market factors.

Adjusted Rental Income represents rental income, excluding material lease buyout payments, which we believe are not reflective of ongoing rental income.

Adjusted Cost of Operations represents cost of operations, excluding LTEIP amortization, which can vary significantly period to period based upon-the performance of the whole company, rather than just property operations.

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, Adjusted Rental Income and Adjusted Cost of Operations may not be comparable to those of other companies and should not be used as an alternative to performance measures ~~of performance~~ calculated in accordance with GAAP. ~~As part~~

See “Analysis of operating income” below for reconciliations of each of these measures to their closest analogous GAAP measure on our consolidated statements of income. Adjusted Rental Income is reconciled to rental income, Adjusted Cost of Operations is reconciled to cost of operations and Net Operating Income is reconciled to operating income.

Operating Results Overview: Three and Nine Months Ended September 30, 2017 and 2016

For the ~~tables below, we have reconciled total NOI to~~three months ended September 30, 2017, net income ~~which~~allocable to common shareholders was $18.1 million or $0.66 per diluted share, compared to $19.7 million or $0.72 per diluted share for the same period in 2016. The decrease was mainly due to a $6.9 million Preferred Redemption Allocation, offset by a $2.7 million increase in NOI with respect to our real estate facilities and reduced preferred distributions. The increase in NOI includes a $3.3 million increase for our Same Park facilities (see below) due primarily to higher realized rent per occupied square foot, offset partially by reduced NOI with respect to facilities we ~~consider the most directly comparable financial measure calculated in accordance with GAAP.~~sold or are holding for development.

~~To present comparative results,~~For the nine months ended September 30, 2017, net income allocable to common shareholders was $69.3 million or $2.53 per diluted share, compared to $50.0 million or $1.84 per diluted share for the ~~purpose~~same period in 2016. The increase was due to a $10.5 million increase in NOI with respect to our real estate facilities, a reduction in interest expense due to the repayment of ~~computing~~debt, and gains on the sale of real estate facilities and development rights. The increase in NOI ~~the tables below exclude amortization~~includes a $12.5 million increase for our Same-Park facilities due primarily to higher realized rent per occupied square foot, offset partially by reduced NOI with respect to facilities we sold or are holding for development.

We analyze our net income in this discussion analysis in two main sections: operating income and then all other components of ~~the Senior Management Long-Term Equity Incentive Plan (“LTEIP”) for the three and six months ended June 30, 2017 and 2016.~~

Our operating income is comprised primarily of our real estate operations, depreciation and amortization expense and general and administrative expenses.

We segregate our real estate activities into (a) same park operations, representing all operating properties acquired prior to January 1, 2015, comprising 27.8 million rentable square feet of our 28.0 million in rentable space at September 30, 2017 (the “Same Park” facilities), (b) non-same park operations, representing those facilities we own that were acquired after January 1, 2015 (the “Non-Same Park” facilities) and (c) assets sold or held for development, representing facilities whose existing operations are no longer part of our ongoing operations, because they were sold or are expected to be developed or converted to alternate use.

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

Same Park and Non-Same Park facilities, offset partially by adjusted costs of operations from assets sold or held for development, as well as lower LTEIP amortization.

Operating income increased $4.4 million and $19.9 million for the three and nine months ended September 30, 2017, respectively, as compared to the same periods in 2016, due primarily to higher rental income, lower general and administrative expenses and lower depreciation expense.

See below for a discussion of depreciation and amortization expense and general and administrative expenses.

The Same Park facilities are those that we have owned and operated since January 1, 2015. We evaluate the operations of these facilities to more effectively evaluate the ongoing performance of our portfolio in 2015, 2016 and 2017. We believe the Same Park information is used by investors and analysts in a similar manner. The following table summarizes the historical operating results of these facilities and certain statistical information related to leasing activity:

Adjusted rental income generated by the Same Park facilities increased 4.4% and 4.6% in the three and nine months ended September 30, 2017, respectively, as compared to the same periods in the prior year. These increases were due primarily to increased annualized realized rental income per occupied square foot and, during the nine month period, an increase in weighted average occupancy.

We believe that high occupancies help maximize our rental income. Accordingly, we seek to maintain a weighted average occupancy over 90%.

During the first nine 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 Northern Virginia and Suburban Maryland markets, new rental rates for the Company improved over expiring rental rates on executed leases as economic conditions and tenant demand remained healthy.

Our future revenue growth will come primarily from potential increases in market rents allowing us to increase rent levels when leases are either renewed with existing tenants or re-leased to new tenants. The following table sets forth the expirations of our existing leases in place at September 30, 2017 over the next five years (dollars and square feet in thousands):

During the three and nine months ended September 30, 2017, we leased approximately 1.8 million and 5.6 million, respectively, in rentable square feet to new and existing customers, with an average increase in rental rates over the previous rates of 5.7% and 4.3%. Approximately 66.8% of our leasing activity for the nine months ended September 30, 2017 represented renewals of leases with existing tenants. See “Analysis of Market Trends” below for further analysis of such data on a by-market basis.

Our ability to re-lease space on expired leases in a way that minimizes vacancy periods and the lease rates that may be achieved are not predictable, because they will depend upon market conditions in the specific submarkets in which each of our properties are located.

Property taxes increased 5.8% and 4.9% during the three and nine months ended September 30, 2017, respectively, as compared to the same periods in the prior year due primarily to higher assessed values. We expect property taxes in the fourth quarter of 2017 to approximate the amount for the third quarter of 2017.

Utilities are dependent primarily upon energy prices and usage levels. Changes in usage levels are driven primarily by weather and temperature. Utilities decreased 1.7% and 1.0% for the three and nine months ended September 30, 2017, respectively, as compared to the same periods in the prior year. It is difficult to estimate future utility costs, because weather, temperature and energy prices are volatile and not predictable.

Repairs and maintenance increased 10.6% and 3.1% during the three and nine months ended September 30, 2017, respectively, as compared to the same periods in the prior year. Repairs and maintenance costs are dependent upon many factors including weather conditions, which can impact repair and maintenance needs, inflation in material and labor costs and random events, and as a result are not readily predictable. We expect to incur incremental repairs and maintenance costs with respect to Hurricane Irma during the fourth quarter of 2017.

Snow removal decreased 73.4% during the nine months ended September 30, 2017 as compared to the same period in 2016. Snow removal costs are weather dependent and therefore not predictable.

Other expenses decreased 2.7% during the three months ended September 30, 2017, and increased 1.4% during the nine months ended September 30, 2017 as compared to the same periods in 2016. These costs are comprised of on site and supervisory personnel, property insurance and other expenses incurred in the operation of our properties.

The following table sets forth historical quarterly trends in the operations of the Same Park facilities for adjusted rental income, adjusted cost of operations, occupancies, realized rents and those expenses which have material seasonal trends:

The following ~~table summarizes~~tables set forth key statistical information with respect to our Same Park leasing activities during the three and nine months ended September 30, 2017. As noted above, our past revenue growth has come from annual inflators, as well as re-leasing of space at current market rates. The following tables summarize the Company’s leasing production by these eight regions for the three and ~~six~~nine months ended ~~June~~September 30, 2017 (in thousands):

During the first ~~six~~nine 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~~Northern Virginia and Suburban 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~~Northern Virginia and Suburban Maryland ~~markets~~ continue to experience soft market conditions as evidenced by continued pressure on occupancy and rental rates. Given lease expirations of ~~1.3~~1.1 million square feet in Northern Virginia and ~~802,000~~712,000 square feet in Suburban Maryland through December 31, 2018, the Company may continue to experience a decrease in rental income in these ~~markets.~~ regions.

~~Scheduled Lease Expirations:~~Non-Same Park facilities: ~~The following table sets forth the lease expirations for all operating assets as of June 30, 2017~~ ~~(dollars and square feet in thousands)~~:

Our ability to re-lease available space will depend upon market conditions in the specific submarkets in which our properties are located. As a result, we cannot predict with certainty the rate at which expiring leases will be re-leased.

~~Concentration of Credit Risk by Industry:~~ ~~The information below depicts the industry concentration of our tenant base as of June 30, 2017. The Company analyzes this concentration to minimize significant industry exposure risk.~~

~~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 SameNon-Same Park facilities ~~constitute 27.8 million~~are comprised of two office buildings in Maryland, with 226,000 rentable square feet ~~representing 99.3%~~and occupancy of ~~the 28.0 million square feet in the Company’s total portfolio as of June~~31.6% at September 30, ~~2017.~~2017 (33.9% at October 23, 2017).

~~Facility Management Fees:~~ ~~Facility management fees, derived from Public Storage (“PS”), account~~ for future potential development into a small portion of the Company’s revenues. During the three months ended June 30, 2017, $124,000 of revenue was recognized from facility management fees compared to $131,000 for the same period in 2016. During the six months ended June 30, 2017, $252,000 of revenue was recognized from facility management fees compared to $259,000 for the same period in 2016.

~~Cost of Operations:~~ ~~The following table summarizes the cost of~~multi-family building. We expect no further material operations for ~~the Company’s properties for the three and six months ended June 30, 2017 and 2016~~ ~~(in thousands)~~:this vacant property until development is complete; as noted above, we do not expect development activity to commence until at least December 2018.

Depreciation and Amortization Expense:Depreciation and amortization ~~expense~~ was ~~$23.6~~$23.8 million for the three months ended ~~June~~September 30, 2017 compared to ~~$25.2~~$24.6 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.

~~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.

~~Supplemental Property Data and Trends:~~ NOI is summarized for the three and six months ended June 30, 2017 and 2016 by region below. See above for more information on NOI, including why the Company presents NOI and how the Company uses NOI. 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.

$70.5 million for the nine months ended September 30, 2017 compared to $74.9 million for the same period in 2016. The three and nine month decreases in depreciation and amortization were due to the cost of certain assets reaching the end of their depreciable lives.

General and Administrative Expenses: General and administrative expenses primarily represent compensation for senior executives, tax compliance, legal and costs associated with being a public company. For the three and nine months ended September 30, 2017, general and administrative expenses decreased $1.2 million, or 41.2%, and $5.0 million, or 41.4%, respectively, compared to the same periods in 2016. The ~~following tables summarize~~three month decrease was primarily due to a reduction in the ~~Same Park~~ongoing LTEIP amortization ($571,000 in 2017 versus $907,000 in 2016), departure of our CFO during the third quarter of 2017 and ~~Non-Same Park operating results by region~~acquisition transaction costs of $328,000 incurred in 2016. The nine month decrease was primarily due to a reduction in the ongoing LTEIP amortization ($2.3 million in 2017 versus $3.8 million in 2016), departure of senior executives in 2016 and 2017 and acquisition transaction costs incurred in 2016 noted above.

Interest and Other Expense: Interest and other expense was $503,000 for the three ~~and six~~ months ended ~~June~~September 30, 2017 compared to $155,000 for the same period in 2016. Interest and other expense was $972,000 for the nine months ended September 30, 2017 compared to $5.5 million for the same period in 2016. ~~In addition,~~The three month increase was due to higher interest capitalized in 2016 as the ~~tables reflect~~Highgate Development began operations in 2017, while the ~~comparative impact~~nine month decrease was primarily due to a repayment of a $250.0 million mortgage note during the second quarter of 2016.

Equity in loss of unconsolidated joint venture: Our equity in loss of unconsolidated joint venture represents our pro rata equity in the earnings of our 95% equity investment in the JV that owns the Highgate Development. We have agreed to provide a construction loan to the Joint Venture, maturing in April, 2019 and having two one-year extension options, of up to $75.0 million. The interest income we receive on the ~~overall adjusted rental income, adjusted~~loan is eliminated against our equity in earnings. During the three and nine months ended September 30, 2017, we recorded an equity loss in the unconsolidated joint venture of $376,000, comprised of $600,000 in revenue, $493,000 in cost of operations, and ~~NOI from properties that have been~~$483,000 in depreciation expense and $758,000, comprised of $642,000 in revenue, $813,000 in cost of operations, and $587,000 in depreciation expense.

The following table summarizes the Joint Venture’s project timeline and updates as of September 30, 2017:

Our cumulative investment in and advances to the Joint Venture, including the fair value of land we contributed, totaled $96.6 million at September 30, 2017.

Gain on sale of real estate facility and gain on sale of development rights: On May 1, 2017, we sold a two-building single-story office park comprising 44,000 square feet, located in Dallas, Texas, for net proceeds of $2.1 million. On March 31, 2017, we sold development rights we had acquired ~~since January 1, 2015, and the impact~~in 2006 in connection with our acquisition of ~~such is included~~a business park in ~~Non-Same Park facilities in the tables below. As part~~Silver Spring, Maryland. When all contingencies of the ~~tables below,~~sale have completed, we will have ~~reconciled total NOI to net income~~ ~~(in thousands)~~:

Liquidity and Capital Resources

~~The following table summarizes Same Park and Non-Same Park recurring capital expenditures (on page 34) and the related percentage~~This section should be read in conjunction with our consolidated statements of ~~NOI by region~~cash flows for the ~~six~~three and nine months ended ~~June~~September 30, 2017 and 2016 ~~(in thousands)~~:

our historical liquidity and capital resources. The ~~following tables summarize Same Park weighted average occupancy rates and annualized realized rental income per square foot by region for~~discussion below sets forth the ~~three and six months ended June 30, 2017 and 2016.~~

~~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 discussionsfactors which we expect will ~~have on~~affect our future ~~operating results.~~

~~Cash and cash equivalents decreased $123.2 million~~capital resources or which may vary substantially 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.

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.

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~~

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.

As a result, in order to grow our asset base, access to 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.

~~The following table depicts~~Our financial profile is characterized by strong credit metrics, including low leverage relative to our total capitalization and operating cash flows. We are a highly rated REIT, as rated by major rating agencies Moody’s and Standard & Poor’s. Our corporate credit rating by Standard and Poors is A-, while our preferred shares are rated BBB by Standard and Poors and Baa2 by Moodys. Our credit profile and ratings enable us to effectively access both the public and private capital ~~expenditures~~ ~~(in thousands)~~:

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~~access 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 targetsmarkets, we target 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~~nine months ended ~~June~~September 30, 2017, the FFO to combined fixed charges and preferred distributions coverage ratio was 5.0 to ~~1.0.~~1.0, excluding the Preferred Redemption Allocation.

We have a $250.0 million revolving Credit Facility that can be expanded to $400.0 million which expires in January, 2022. We use the Credit Facility along with bank term debt, as temporary “bridge” financing until we are able to raise longer term capital. Historically we have funded our long-term capital requirements with retained operating cash flow and proceeds from the issuance of common and preferred securities. We will select among these sources of capital based upon availability, relative cost, the impact of constraints of certain forms of capital on our operations (such as covenants), as well as the desire for leverage.

~~Non-GAAP Supplemental Disclosure Measure: Funds from Operations:~~Short-term Liquidity and Capital Resource Analysis: ~~Management believes~~We believe that ~~Funds from Operations (“FFO”)~~our net cash provided by our operating activities will continue to be sufficient to enable us to meet our ongoing requirements for debt service, capital expenditures and ~~FFO, as adjusted~~distributions to our shareholders for the foreseeable future.

As of September 30, 2017, we had no balance outstanding on our Credit Facility. In the last five years, we have retained an average of $40 to $50 million in operating cash flow per year. Retained operating cash flow represents cash flow provided by operating activities, less shareholder and unit holder distributions and capital expenditures. We expect to invest an additional $9.8 million with respect to the Highgate Development.

Potential future uses of capital in the next twelve months include the acquisition of additional real estate facilities, and potential future sources include the potential sale of real estate facilities.

~~FFO and FFO,~~Capital Expenditures: We define recurring capital expenditures 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 coststhose necessary to maintain and operate our real estate at its current economic value. Nonrecurring capital improvements include property renovations and expenditures related to repositioning acquisitions. The following table sets forth our capital expenditures paid for the ~~operating performance of the Company’s properties, which are significant economic costs~~nine months ended September 30, 2017 and ~~could materially affect the Company’s results of operations.~~2016, respectively, on an aggregate and per square foot basis:

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.

~~____________________________~~The increase in Same Park recurring capital expenditures of $6.9 million, or 29.2%, was primarily due to transaction costs related to large renewals and leasing production in the Same Park portfolio during 2017.

Acquisitions of real estate facilities: We have acquired real estate facilities in the past, and we continue to seek to acquire additional real estate facilities, however, there is significant competition to acquire existing facilities and there can be no assurance as to the level of facilities we may acquire.

Development of real estate facilities: As noted above, we have an additional 123,000 building located within The Mile that we are seeking to develop into another multi-family complex. There can be no assurance as to the timing or amount of any investment that may occur; however, we do not expect to incur any significant development costs on this potential project until at least December 2018.

Repurchase of Common Stock: No shares of common stock were repurchased under the board-approved common stock repurchase program during the nine months ended September 30, 2017 or the year ended December 31, 2016. As of September 30, 2017, management has the authorization to repurchase an additional 1,614,721 shares. However, we have no plans at this time to repurchase additional shares.

Requirement to Pay Distributions:For all periods presented herein, we have elected to be treated as a REIT, as defined in the Code. As a REIT, we do not incur federal income tax on our REIT taxable income (generally, net rents and gains from real property, dividends and interest) that is fully distributed each year (for this purpose, certain distributions paid in a subsequent year may be considered), and if we meet certain organizational and operational rules. We believe we have met these requirements in all periods presented herein, and we expect to continue to elect and qualify as a REIT.

During the first quarter of 2017, the Board increased our 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.

We paid REIT qualifying distributions of $107.1 million ($37.8 million to preferred shareholders and $69.4 million to common shareholders) and $102.4 million ($41.5 million to preferred shareholders and $60.9 million to common shareholders) during the nine months ended September 30, 2017 and 2016, respectively.

Our consistent, long-term dividend policy has been to distribute our taxable income in order to maintain our REIT status. Future quarterly distributions with respect to the common shares will continue to be determined based upon our REIT distribution requirements and will be funded with cash provided by operating activities.

Funds from Operations (“FFO”) and FFO per share are non-GAAP measures defined by the National Association of Real Estate Investment Trusts and are considered helpful measures of REIT performance by REITs and many REIT analysts. FFO represents net income before real estate depreciation, gains or losses from sales and impairment charges, which are excluded because they are based upon historical real estate costs and assume that building values diminish ratably over time, while we believe that real estate values fluctuate due to market conditions. FFO per share represents FFO allocable to common and dilutive shares, ~~as adjusted, increased $6.8 million~~divided by aggregate common and ~~$16.1 million~~dilutive shares. FFO and FFO per share are not a substitute for ~~the three~~net income or earnings per share. FFO is not a substitute for GAAP net cash flow in evaluating our liquidity or ability to pay dividends, because it excludes investing 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.financing activities presented on our consolidated statements of cash flows. In addition, other REITs may compute these measures differently, so comparisons among REITs may not be helpful.

~~Related Party Transactions:~~The following table reconciles from net income allocable to common shareholders to FFO and net income per share to FFO per share 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.(amounts in thousands, except per share data):

We also present “Core FFO per share,” a non-GAAP measure that represents FFO per share excluding the net impact of (i) Preferred Redemption Allocation, (ii) separation settlement payments, as well as charges or reversals related 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 allocatedstock based compensation, due to the ~~Company totaled $132,000~~departure of senior executives and ~~$123,000~~(iii) certain other non-cash and/or nonrecurring income or expense items. We review Core FFO per share to evaluate our ongoing operating performance, and we believe it is used by investors and REIT analysts in a similar manner. However, Core FFO per share is not a substitute for net income per share. Because other REITs may not compute Core FFO per share in the ~~three months ended June 30, 2017 and 2016, respectively, and $265,000 and $247,000 for~~same manner as we do, may not use the ~~six months ended June 30, 2017 and 2016, respectively. Costs allocated~~same terminology or may not present such a measure, Core FFO per share may not be comparable among REITs.

The following table reconciles FFO per share 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.Core FFO per share:

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~~As of September 30, 2017, the Company is scheduled to pay cash dividends of ~~$50.4~~$41.4 million per year on its

Our significant contractual obligations as of September 30, 2017 and their impact on our cash flows and liquidity are summarized below (in thousands):

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~~The Company had no debt ~~as a percentage of total equity (based on book values) was 5.6%~~outstanding as of ~~June~~September 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.

The Company’s management, with the participation of the Company’s Chief Executive Officer, ~~and~~who is also serving as acting 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~~September 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~~September 30, 2017, the Company’s Chief Executive Officer, ~~and~~who is also serving as acting 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) that occurred during the fiscal quarter ended ~~June~~September 30, 2017 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

The Company currently is not subject to any material litigation other than routine litigation and administrative proceedings arising in the ordinary course of business.

There have been no material changes to the risk factors included in our Annual Report on Form 10-K for the year ended December 31, 2016.

The Company’s Board of Directors has authorized the repurchase, from time to time, of up to 6.5 million shares of the Company’s common stock on the open market or in privately negotiated transactions. The authorization has no expiration date. Purchases will be made subject to market conditions and other investment opportunities available to

During the three months ended ~~June~~September 30, 2017, there were no shares of the Company’s common stock repurchased. As of ~~June~~September 30, 2017, 1,614,721 shares remain available for purchase under the program.
