TO OUR SHAREHOLDERS PSB—Positioned for an Emerging Recovery Nearly four years after the historical economic crisis of 2008, more indications are emerging that a broader base of positive economic conditions are at hand, which will have particular advantages to PS Business Parks (“PSB”). In 2012, several elements of a recovery surfaced, including employment growth, new business creation, an improving housing recovery and strong corporate profits. More specific to our industry, these factors have taken commercial occupancy levels to multi-year highs. There are fewer vacant buildings across many markets, and minimal new inventory has been built. In essence, the supply-and-demand ratio has begun to shift in favor of owners. The strategies PSB has deployed over this multi-year, slow growth post-crisis period have positioned the Company for exceptional opportunities. The leadership team at PSB, which now has a combined average tenure with the Company in excess of a decade, is battle tested and, even more importantly, equipped to deliver superior results due to the unique attributes of our platform. PSB is not only a successful survivor of an environment that has disabled many competitors, it is well positioned to thrive in whatever form of emerging recovery is at hand. Here are a number of reasons why I am so encouraged by the opportunities ahead for PSB as we reflect on 2012 and enter into 2013. Our Customers. PSB’s priority is to own and operate properties that cater to users who appreciate the advantages of locating their businesses in a multi-building business park environment. With a portfolio comprised of over 28 million square feet throughout 102 business parks, PSB’s average customer occupies just over 5,000 square feet. We view this as a strategic “sweet spot” and focus our primary efforts to serve customers who some characterize as “management intensive” due to their smaller size. PSB’s customer base, which is now comprised of over 4,600 entities, is spread across a wide array of industries, a true cross section of the American business community. There is a vibrant flow of real estate demand within a business population that is far deeper in quantity and size in any given market compared to a more finite pool of larger users. We can continuously tap a diverse and broad array of potential customers, even in the depths of economic recessions. By example, PSB sourced scores of new customers between 2009 and 2011 as approximately 2,500 new companies chose to locate in our parks and company occupancy levels held relatively steady. In 2012 alone, PSB welcomed a record level of new customers to the portfolio, leasing 3.6 million square feet to nearly 1,000 businesses taking first time occupancy. Small businesses are the engine of the U.S. economy and PSB’s core customer base, where 80% of our business/leasing volume is derived. We stay as close as possible to our customers and don’t outsource this responsibility to third party management firms. PSB can best serve its customers by having our own personnel respond to their needs directly. Our personnel are trained and motivated to provide a level of service most users don’t find in comparably sized properties. 2012 Same Park1 Portfolio Performance. Compared to 2009 through 2011, several key metrics improved in 2012 (see chart below), including Net Operating Income (NOI)2 rental rates, transaction cost per square foot and year-over-year Same Park Operating History Occupancy NOI Change y c n a p u c c O e g a r e v A d e t h g i e W 94.0% 92.0% 90.0% 88.0% 3.0% 2.0% 1.0% 0.0% (1.0%) (2.0%) (3.0%) (4.0%) (5.0%) e g n a h C I O N 2008 2009 2010 2011 2012 Same Park NOI Trend Reflects Improving Market Conditions. (1) In order to evaluate the performance of the Company’s overall portfolio over comparable periods, management analyzes the operating performance of properties owned and operated throughout both comparable periods (herein referred to as “Same Park”). (2) Net operating income is rental income, as defined by U.S. generally accepted accounting principles (“GAAP”), less cost of operations, as defined by GAAP, excluding depreciation and amortization and certain non-recurring items. weighted average occupancy. Due to an average lease term of just over three years, PSB has the ability to “mark to market” lease rates at a faster clip than owners focused on larger users who typically sign much longer term leases. The statistics tied to this metric are becoming more favorable (in 2011 cash rent spreads decreased 8.3% while in 2012 they decreased 6.2%) as we now are releasing into a pool of transactions signed in the depths of the 2008 to 2011 market correction. These previously reduced rental rates are now being reset to improving market rates on both new and renewing lease transactions. All told, 2012 leasing activity took Same Park NOI positive for the first time in four years to 0.7%. The statistics look favorable heading into 2013 with 27% of our leased portfolio expiring and with many markets beginning to post higher rental rates. Investments. Beginning in 2010 and through 2012, PSB acquired approximately nine million square feet (deploying approximately $900 million in capital) of well located assets. On top of these investments, we expended another $45 million to reposition and lease these properties, typically re-tooling buildings to accommodate smaller multi-tenancy with spaces that are “made-ready” for occupancy. These properties have been characterized as “value-add” due to their inferior in-place occupancy and revenue levels when acquired. PSB’s strategy has been to invest in underperforming assets that are well matched to our operational strengths, reposition them if necessary to a size that meets our customer size and then aggressively lease them. Particular focus was placed in Washington D.C. (office assets) and Austin (flex assets) in 2010 and Northern California (industrial and flex assets) in 2011. In 2012, we acquired approximately one million square feet in Seattle (industrial assets) and another 226,000 square feet in Austin (flex assets) with both of these markets showing promise. The mixture of office, flex and industrial assets acquired over the last three years has been dictated by the value opportunity we have uncovered, knowing that in any of the three product types we have the ability to deliver strong investment returns once the assets are repositioned and occupancy is stabilized. The over-arching goal is to meet or exceed the typical levels of occupancy we achieve in our stabilized and long-held assets. Having bought the assets well below replacement cost gives us the ability to generate solid investment returns, even after expending significant repositioning dollars required in some cases to standardize multi-tenant parks to a more typical PSB customer need. This investment activity has been and will be an important component of the Company’s revenue and NOI growth. From this pool, thus far PSB improved occupancy by 750 basis points (see occupancy chart below), specifically generating $60 million of NOI y c n a p u c c O 90.0% 85.0% 80.0% 75.0% 70.0% 65.0% 60.0% Occupancy Growth of Acquired Assets Average Occupancy at Acquisition Average Occupancy at 12-31-2012 87.1% 86.1% 80.3% 70.8% Assets Acquired in 2010 Assets Acquired in 2011 Acquired Assets Offer Solid Occupancy Growth Opportunities. in 2012. There is solid opportunity to close the occupancy “gap” and produce strong NOI as these assets had current occupancy of 82.6% at the end of 2012 while PSB’s Same Park occupancy stood at 92.7%. I am particularly proud of the work and effort our team has put forth in driving this three-year growth initiative (expanding our portfolio by 47%). This has enabled PSB to generate increasing levels of NOI with more upside with continued lease up as well as marking to market expiring leases. All of this has been achieved while expanding PSB’s presence in some of the most vibrant markets in the United States. Even Stronger Balance Sheet. From the darkest days of the financial crisis through today, there has been no question that PSB’s balance sheet and financial posture are admirably resilient. Our long-held premise of structuring the Company’s foundation upon a conservative financial platform continues to distinguish PSB. With that, decisions we make adhere to a low risk, high cash flow financial strategy with a proven track record of utilizing preferred equity as a primary source of capital. In 2012, a historically low interest rate environment brought forth several significant choices for PSB to yet again enhance the strength of its balance sheet. In the last 12 months, we raised a company record amount of preferred equity, repaid borrowings on our line of credit and reduced the size of a loan tied to the acquisition of the $520 million Northern California industrial portfolio, all while generating $40 million of free cash flow. n o p u o C e c a l P n i e g a r e v A 7.09% 6.89% 6.69% 6.49% 6.29% 6.09% 5.89% 2012 Preferred Equity Issuance Activity 6.73% $350 (@6.00%) 6.33% $230 (@6.45%) $230 (@5.75%) Q1 Q2 6.13% Q3 Preferred Equity Raised at Historical Low Coupons. $380 $340 $300 $260 $220 $180 ) s n o i l l i M n i ( d e u s s I y t i u q E d e r r e f e r P In 2012, PSB was particularly fortunate to be able to redeem $529 million of outstanding preferred equity, then replacing it with newly issued preferred equity at much lower coupons. We went to the market three times in 2012, raising a total of $810 million, with each offering outperforming the last in terms of coupon. PSB was able to reduce the blended coupon on outstanding preferred equity from 7.0% to 6.1%, saving approximately $5 million in annual distribution costs. Also, our fixed charge coverage ratio remained very healthy at 3.1x, which is in the upper tier of any publicly traded REIT. It is quite admirable to have such a strong balance sheet with the macro financial pressures that many other entities (public and private) face. Conclusion For the reasons noted, we remain optimistic that PSB is well positioned to continue to deliver exceptional shareholder returns. In 2012, the Company produced a total return to shareholders of 20%, the strongest level since 2006. In the coming year and beyond, the factors that should reward our efforts include improving market conditions and employment growth driven by strong corporate performance and continued small business development. In addition, PSB is a standout when we choose to acquire assets, with our uncompromised balance sheet and proven efficient due diligence processes, while still adhering to consistent historical underwriting and investment hurdles that lead to enhanced net asset value. Most importantly, we are at an advantage due to the quality and dedication of our team members at every level. PSB employees take pride in outperforming markets, embracing the challenges of ever changing markets and customer demands, while once again finding ways to deliver respectable shareholder returns. Thank you for your confidence in our abilities. Sincerely, Joseph D.

The White Paper defines FFO as net income, computed in accordance with generally accepted accounting principles (“GAAP”), before depreciation, amortization, gains or losses on asset dispositions, net income allocable to noncontrolling interests — common units, net income allocable to restricted stock unit holders, impairment charges and nonrecurring items. FFO should be analyzed in conjunction with net income. However, FFO should not be viewed as a substitute for net income as a measure of operating performance or liquidity as it does not reflect depreciation and amortization costs or the level of capital expenditure and leasing costs necessary to maintain the operating performance of the Company’s properties, which are significant economic costs and could materially impact the Company’s results from operations. Other REITs may use different methods for calculating FFO and, accordingly, the Company’s FFO may not be comparable to other real estate companies. (2) Funds Available for Distribution (“FAD”) is computed by adjusting consolidated FFO for recurring capital improvements, which the Company defines as those costs incurred to maintain the assets’ value, tenant improvements, lease commissions, straight-line rent, stock compensation expense, amortization of lease incentives and tenant improvement reimbursements, in-place lease adjustment and the effect of redemption/repurchase of preferred equity. Like FFO, the Company considers FAD to be a useful measure for investors to evaluate the operations and cash flows of a REIT. FAD does not represent net income or cash flow from operations as defined by GAAP.

The Company owns 8.4 million square feet of industrial space that has characteristics similar to the warehouse component of the flex space as well as ample dock access. In addition, the Company owns 5.0 million square feet of low-rise office space, generally either in business parks that combine office and flex space or in submarkets where the market demand is more office focused. 3 The Company’s commercial properties typically consist of business parks with low-rise buildings, ranging from one to 48 buildings per park, located on parcels of various sizes and comprising from approximately 12,000 to 3.3 million aggregate square feet of rentable space. Facilities are managed through either on-site management or offices central to the facilities. Parking is generally open but in some instances is covered. The ratio of parking spaces to rentable square feet ranges from two to six per thousand square feet depending upon the use of the property and its location. Office space generally requires a greater parking ratio than most industrial uses. The Company may acquire properties that do not have these characteristics. The tenant base for the Company’s facilities is diverse. The portfolio can be bifurcated into those facilities that service small to medium-sized businesses and those that service larger businesses. Approximately 34.2% of in-place rents from the portfolio are derived from facilities that serve small to medium-sized businesses. A property in this facility type is typically divided into units ranging in size from 500 to 4,999 square feet and leases generally range from one to three years. The remaining 65.8% of in-place rents from the portfolio are derived from facilities that serve larger businesses, with units greater than or equal to 5,000 square feet. The Company also has several tenants that lease space in multiple buildings and locations. The U.S. Government is the largest tenant with multiple leases encompassing approximately 870,000 square feet or 6.1% of the Company’s annualized rental income. The Company currently owns properties in eight states and it may expand its operations to other states or reduce the number of states in which it operates. Properties are acquired for both income and potential capital appreciation; there is no limitation on the amount that can be invested in any specific property. Although there are no restrictions on our ability to expand our operations into foreign markets, we currently operate solely within the United States and have no foreign operations. The Company owns land which may be used for the development of commercial properties. The Company owns approximately 6.4 acres of such land in Northern Virginia, 11.5 acres in Portland, Oregon and 10.0 acres in Dallas, Texas as of December 31, 2012. Operating Partnership The properties in which the Company has an equity interest generally are owned by the Operating Partnership. Through this organizational structure, the Company has the ability to acquire interests in additional properties in transactions that could defer the contributors’ tax consequences by causing the Operating Partnership to issue equity interests in return for interests in properties. The Company is the sole general partner of the Operating Partnership. As of December 31, 2012, the Company owned 76.9% of the common partnership units of the Operating Partnership, and the remainder of such common partnership units were owned by PS. The common units owned by PS may be redeemed by PS from time to time, subject to the provisions of our charter, for cash or, at our option, shares of our common stock on a one-for-one basis. Also as of December 31, 2012, in connection with the Company’s issuance of publicly traded Cumulative Preferred Stock, the Company owned 35.4 million preferred units of the Operating Partnership of various series with an aggregate redemption value of $885.0 million with terms substantially identical to the terms of the publicly traded depositary shares each representing 1/1,000 of a share of 5.750% to 6.875% Cumulative Preferred Stock of the Company. As the general partner of the Operating Partnership, the Company has the exclusive responsibility under the Operating Partnership Agreement to manage and conduct the business of the Operating Partnership. The Board of Directors directs the affairs of the Operating Partnership by managing the Company’s affairs. The Operating Partnership is responsible for, and pays when due, its share of all administrative and operating expenses of the properties it owns. 4 The Company’s interest in the Operating Partnership entitles it to share in cash distributions from, and the profits and losses of, the Operating Partnership in proportion to the Company’s economic interest in the Operating Partnership (apart from tax allocations of profits and losses to take into account pre-contribution property appreciation or depreciation). The Company, since 1998, has paid per share dividends on its common and preferred stock that track, on a one-for-one basis, the amount of per unit cash distributions the Company receives from the Operating Partnership in respect of the common and preferred partnership units in the Operating Partnership that are owned by the Company. Cost Allocation and Administrative Services Pursuant to a cost sharing and administrative services agreement, the Company shares costs with PS for certain administrative services. These services include investor relations, legal, corporate tax and information systems. Under this agreement, costs are allocated to the Company in accordance with its proportionate share of these costs. These allocated costs totaled $441,000, $442,000 and $543,000 for the years ended December 31, 2012, 2011 and 2010, respectively. Common Officers and Directors with PS Ronald L. Havner, Jr., Chairman of the Company, is also the Chairman of the Board, Chief Executive Officer and President of PS. Gary E. Pruitt, an independent director of the Company is also a trustee of PS. The Company engages additional executive personnel who render services exclusively for the Company. However, it is expected that certain officers of PS will continue to render services for the Company as requested pursuant to the cost sharing and administrative services agreement. Property Management The Company manages commercial properties owned by PS, which are generally adjacent to self-storage facilities, for a management fee of 5% of the gross revenues of such properties in addition to reimbursement of direct costs. The property management contract with PS is for a seven-year term with the agreement automatically extending for an additional one-year period upon each one-year anniversary of its commencement (unless cancelled by either party). Either party can give notice of its intent to cancel the agreement upon expiration of its current term. Management fee revenue derived from this management contract with PS totaled $649,000, $684,000 and $672,000 for the years ended December 31, 2012, 2011 and 2010, respectively. PS also provides property management services for the self-storage component of two assets owned by the Company. These self-storage facilities, located in Palm Beach County, Florida, operate under the “Public Storage” name. Either the Company or PS can cancel the property management contract upon 60 days’ notice. Management fee expenses under the contract were $55,000, $52,000 and $48,000 for the years ended December 31, 2012, 2011 and 2010, respectively. Management Joseph D. Russell, Jr. leads the Company’s senior management team. Mr. Russell is President and Chief Executive Officer of the Company. The Company’s senior management includes: John W. Petersen, Executive Vice President and Chief Operating Officer; Edward A. Stokx, Executive Vice President and Chief Financial Officer; Maria R. Hawthorne, Executive Vice President, East Coast; Trenton A. Groves, Vice President and Corporate Controller; Coby A. Holley, Vice President (Pacific Northwest Division); Robin E. Mather, Vice President (Southern California Division); William A. McFaul, Vice President (Washington Metro Division); Ross K. Parkin, Vice President, Acquisitions and Dispositions; Eddie F. Ruiz, Vice President and Director of Facilities; Viola I. Sanchez, Vice President (Southeast Division); Richard E. Scott, Vice President (Northern California Division); Eugene Uhlman, Vice President, Construction Management; and David A. Vicars, Vice President (Midwest Division). 5 REIT Structure If certain detailed conditions imposed by the Code and the related Treasury Regulations are met, an entity, such as the Company, that invests principally in real estate and that otherwise would be taxed as a corporation may elect to be treated as a REIT. The most important consequence to the Company of being treated as a REIT for federal income tax purposes is that the Company can deduct dividend distributions (including distributions on preferred stock) to its shareholders, thus effectively eliminating the “double taxation” (at the corporate and shareholder levels) that typically results when a corporation earns income and distributes that income to shareholders in the form of dividends. The Company believes that it has operated, and intends to continue to operate, in such a manner as to qualify as a REIT under the Code, but no assurance can be given that it will at all times so qualify. To the extent that the Company continues to qualify as a REIT, it will not be taxed, with certain limited exceptions, on the taxable income that is distributed to its shareholders. Operating Strategy The Company believes its operating, acquisition and finance strategies combined with its diversified portfolio produces a low risk, stable growth business model. The Company’s primary objective is to grow shareholder value. Key elements of the Company’s growth strategy include: Maximize Net Cash Flow of Existing Properties: The Company seeks to maximize the net cash flow generated by its properties by (i) maximizing average occupancy rates, (ii) achieving the highest possible levels of realized monthly rents per occupied square foot and (iii) controlling its operating cost structure by improving operating efficiencies and economies of scale. The Company believes that its experienced property management personnel and comprehensive systems combined with increasing economies of scale enhance the Company’s ability to meet these goals. The Company seeks to increase occupancy rates and realized monthly rents per square foot by providing its field personnel with incentives to lease space to credit tenants and to maximize the return on investment in each lease transaction. The Company seeks to maximize its cash flow by controlling capital expenditures associated with maintaining and re-leasing space by acquiring and owning properties with easily reconfigured space that appeal to a wide range of tenants. Focus on Targeted Markets: The Company intends to continue investing in markets that have characteristics which enable them to be competitive economically. The Company believes that markets with some combination of above average population growth, job growth, higher education levels and personal income will produce better overall economic returns. The Company targets individual properties in high barrier to entry markets that are close to critical infrastructure, middle to high income housing, universities and have easy access to major transportation arteries. Reduce Capital Expenditures and Increase Occupancy Rates by Providing Flexible Properties and Attracting a Diversified Tenant Base: By focusing on properties with easily reconfigurable space, the Company believes it can offer facilities that appeal to a wide range of potential tenants, which aids in reducing the capital expenditures associated with re-leasing space. The Company believes this property flexibility also allows it to better serve existing tenants by accommodating expansion and contraction needs. In addition, the Company believes that a diversified tenant base combined with flexible parks helps it maintain occupancy rates by enabling it to attract a greater number of potential users to its space. Provide Superior Property Management: The Company seeks to provide a superior level of service to its tenants in order to maintain occupancy and increase rental rates, as well as minimize customer turnover. The Company’s property management offices are located on-site or regionally, providing tenants with convenient access to management and helping the Company maintain its properties and convey a sense of quality, order and security. The Company has significant experience in acquiring properties managed by others and thereafter improving tenant satisfaction, occupancy levels, renewal rates and rental income by implementing established tenant service programs. 6 Financing Strategy The Company’s primary objective in its financing strategy is to maintain financial flexibility and a low risk capital structure. Key elements of this strategy are: Retain Operating Cash Flow: The Company seeks to retain significant funds (after funding its distributions and capital improvements) for additional investments. During the years ended December 31, 2012 and 2011, the Company distributed 41.4% and 37.4%, respectively, of its funds from operations (“FFO”) to common shareholders/unit holders. FFO is computed in accordance with the White Paper on FFO approved by the Board of Governors of the National Association of Real Estate Investment Trusts (“NAREIT”). The White Paper defines FFO as net income, computed in accordance with U.S. generally accepted accounting principles (“GAAP”), before depreciation, amortization, gains or losses on asset dispositions, net income allocable to noncontrolling interests — common units, net income allocable to restricted stock unit holders, impairment charges and nonrecurring items. FFO is a non-GAAP financial measure and should be analyzed in conjunction with net income. However, FFO should not be viewed as a substitute for net income as a measure of operating performance as it does not reflect depreciation and amortization costs or the level of capital expenditure and leasing costs necessary to maintain the operating performance of the Company’s properties, which are significant economic costs and could materially impact the Company’s results of operations. Other REITs may use different methods for calculating FFO and, accordingly, the Company’s FFO may not be comparable to other real estate companies’ funds from operations. See Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Non-GAAP Supplemental Disclosure Measure: Funds from Operations,” for a reconciliation of FFO and net income allocable to common shareholders and for information on why the Company presents FFO. Perpetual Preferred Stock/Units: The primary source of leverage in the Company’s capital structure is perpetual preferred stock or equivalent preferred units in the Operating Partnership. This method of financing eliminates interest rate and refinancing risks as the dividend rate is fixed and the stated value or capital contribution is not required to be repaid. In addition, the consequences of defaulting on required preferred distributions are less severe than with debt. The preferred shareholders may elect two additional directors if six quarterly distributions go unpaid, whether or not consecutive. Throughout this Form 10-K, we use the term “preferred equity” to mean both the preferred stock issued by the Company (including the depositary shares representing interests in that preferred stock) and the preferred partnership units issued by the Operating Partnership and the term “preferred distributions” to mean dividends and distributions on the preferred stock and preferred partnership units. Debt Financing: The Company, from time to time, has used debt financing to facilitate real estate acquisitions and other capital allocations. The primary source of debt the Company has historically relied upon to provide short-term capital is its $250.0 million unsecured line of credit (the “Credit Facility”). In addition, during 2011, in connection with its $520.0 million portfolio acquisition in Northern California, the Company obtained a $250.0 million unsecured three-year term loan and assumed a $250.0 million mortgage note. Access to Capital: The Company targets a minimum ratio of FFO to combined fixed charges and preferred distributions paid of 3.0 to 1.0. Fixed charges include interest expense. Preferred distributions include amounts paid to preferred shareholders and preferred Operating Partnership unit holders. For the year ended December 31, 2012, the FFO to combined fixed charges and preferred distributions paid ratio was 3.1 to 1.0, excluding the charge for the issuance costs related to the redemptions of preferred equity. The Company believes that its financial position enables it to access capital to finance future growth. Subject to market conditions, the Company may add leverage to its capital structure. Competition Competition in the market areas in which many of the Company’s properties are located is significant and has from time to time reduced the occupancy levels and rental rates of, and increased the operating expenses of, certain of these properties. Competition may be accelerated by any increase in availability of funds for investment in real estate. Barriers to entry are relatively low for those with the necessary capital and the 7 Company competes for property acquisitions and tenants with entities that have greater financial resources than the Company. Sublease space and unleased developments are expected to continue to provide competition among operators in certain markets in which the Company operates. While the Company will have to respond to market demands, management believes that the combination of its ability to offer a variety of options within its business parks and the Company’s financial stability provide it with an opportunity to compete favorably in its markets. The Company’s properties compete for tenants with similar properties located in its markets primarily on the basis of location, rent charged, services provided and the design and condition of improvements. The Company believes it possesses several distinguishing characteristics that enable it to compete effectively in the flex, office and industrial space markets. The Company believes its personnel are among the most experienced in these real estate markets. The Company’s facilities are part of a comprehensive system encompassing standardized procedures and integrated reporting and information networks. The Company believes that the significant operating and financial experience of its executive officers and directors combined with the Company’s capital structure, national investment scope, geographic diversity and economies of scale should enable the Company to compete effectively. Investments in Real Estate Facilities As of December 31, 2012, the Company owned and operated 28.3 million rentable square feet comprised of 102 business parks in eight states compared to 27.2 million rentable square feet at December 31, 2011. Summary of Business Model The Company has a diversified portfolio. It is diversified geographically in eight states and has a diversified customer mix by size and industry concentration. The Company believes that this diversification combined with a conservative financing strategy, focus on markets with strong demographics for growth and our operating that mitigates risk and provides strong long-term growth strategy gives the Company a business model opportunities. Restrictions on Transactions with Affiliates The Company’s Bylaws provide that the Company may engage in transactions with affiliates provided that a purchase or sale transaction with an affiliate is (i) approved by a majority of the Company’s independent directors and (ii) fair to the Company based on an independent appraisal or fairness opinion. Borrowings As of December 31, 2012, the Company had outstanding mortgage notes payable of $268.1 million compared to $282.1 million at December 31, 2011. The decrease in outstanding mortgage notes payable was due to the repayment of a $13.2 million mortgage note in November, 2012. Subsequent to December 31, 2012, the Company repaid two mortgage notes payable totaling $18.1 million. See Notes 5 and 6 to the consolidated financial statements for a summary of the Company’s outstanding borrowings as of December 31, 2012. The Company has a line of credit (the “Credit Facility”) with Wells Fargo Bank, National Association (“Wells Fargo”) which expires on August 1, 2015. The Credit Facility has a borrowing limit of $250.0 million. The rate of interest charged on borrowings is equal to a rate ranging from the London Interbank Offered Rate (“LIBOR”) plus 1.00% to LIBOR plus 1.85% depending on the Company’s credit ratings. Currently, the Company’s rate under the Credit Facility is LIBOR plus 1.10%. In addition, the Company is required to pay an annual facility fee ranging from 0.15% to 0.45% of the borrowing limit depending on the Company’s credit ratings (currently 0.15%). The Company had no balance outstanding on the Credit Facility at December 31, 2012. The Company had $185.0 million outstanding on the Credit Facility at an interest rate of 1.41% at December 31, 2011. The Company had $791,000 and $1.1 million of unamortized commitment fees as of December 31, 2012 and 2011, respectively. The Credit Facility requires the Company to meet certain covenants, with which the Company was in compliance at December 31, 2012 and 2011. Interest on outstanding borrowings is payable monthly. 8 In connection with the Northern California Portfolio acquisition described in Note 3, the Company entered into a term loan on December 20, 2011 with Wells Fargo, as Administrative Agent (the “Term Loan”). Pursuant to the Term Loan, the Company borrowed $250.0 million for a three year term through December 31, 2014. The maturity date of the Term Loan Agreement can be extended by one year at the Company’s election. Interest on the amounts borrowed under the Term Loan accrues based on an applicable rate ranging from LIBOR plus 1.15% to LIBOR plus 2.25% depending on the Company’s credit ratings. Currently, the Company’s rate under the Term Loan is LIBOR plus 1.20%. The Company had $200.0 million outstanding on the Term Loan at an interest rate of 1.41% at December 31, 2012 and $250.0 million outstanding at an interest rate of 1.50% at December 31, 2011. The Company had $383,000 and $729,000 of unamortized commitment fees as of December 31, 2012 and 2011, respectively. The covenants and events of default contained in the Credit Facility are incorporated into the Term Loan by reference, and the Term Loan is cross-defaulted to the Credit Facility. The Term Loan can be repaid in full or part at any time prior to its maturity without penalty. On February 9, 2011, the Company entered into an agreement with PS to borrow $121.0 million with a maturity date of August 9, 2011 at an interest rate of LIBOR plus 0.85%. The Company repaid, in full, the note payable to PS upon maturity. The Company has broad powers to borrow in furtherance of the Company’s objectives. The Company has incurred in the past, and may incur in the future, both short-term and long-term indebtedness to facilitate real estate acquisitions and other capital allocations. Employees As of December 31, 2012, the Company employed 161 individuals, primarily personnel engaged in property operations. Insurance The Company believes that its properties are adequately insured. Facilities operated by the Company have liability and extended including fire, earthquake, historically been covered by comprehensive insurance, coverage from nationally recognized carriers. Environmental Matters Compliance with laws and regulations relating to the protection of the environment, including those regarding the discharge of material into the environment, has not had any material effect upon the capital expenditures, earnings or competitive position of the Company. Substantially all of the Company’s properties have been subjected to Phase I environmental reviews. Such reviews have not revealed, nor is management aware of, any probable or reasonably possible environmental costs that management believes would have a material adverse effect on the Company’s business, assets or results of operations, nor is the Company aware of any potentially material environmental liability. See Item 1A, “Risk Factors” for additional information. ITEM 1A. RISK FACTORS In addition to the other information in our Annual Report on Form 10-K, you should consider the risks described below that we believe may be material to investors in evaluating the Company. This section contains forward-looking statements, and in considering these statements, you should refer to the qualifications and limitations on our forward-looking statements that are described in Item 1, “Business — Forward-Looking Statements.” 9 Since our business consists primarily of acquiring and operating real estate, we are subject to the risks related to the ownership and operation of real estate that can adversely impact our business and financial condition. The value of our investments may be reduced by general risks of real estate ownership: Since we derive substantially all of our income from real estate operations, we are subject to the general risks of acquiring and owning real estate-related assets, including: • • • • • • • • • • • • • • changes in the national, state and local economic climate and real estate conditions, such as oversupply of or reduced demand for commercial real estate space and changes in market rental rates; how prospective tenants perceive the attractiveness, convenience and safety of our properties; difficulties in consummating and financing acquisitions and developments on advantageous terms and the failure of acquisitions and developments to perform as expected; our ability to provide adequate management, maintenance and insurance; natural disasters, such as earthquakes, hurricanes and floods, which could exceed the aggregate limits of our insurance coverage; the expense of periodically renovating, repairing and re-letting spaces; the impact of environmental protection laws; compliance with federal, state, and local laws and regulations; increasing operating and maintenance costs, including property taxes, insurance and utilities, if these increased costs cannot be passed through to tenants; adverse changes in tax, real estate and zoning laws and regulations; increasing competition from other commercial properties in our market; tenant defaults and bankruptcies; tenants’ right to sublease space; and concentration of properties leased to non-rated private companies with uncertain financial strength. Certain significant costs, such as mortgage payments, real estate taxes, insurance and maintenance, generally are not reduced even when a property’s rental income is reduced. In addition, environmental and tax laws, interest rate levels, the availability of financing and other factors may affect real estate values and property income. Furthermore, the supply of commercial space fluctuates with market conditions. If our properties do not generate sufficient income to meet operating expenses, including any debt service, tenant improvements, lease commissions and other capital expenditures, we may have to borrow additional amounts to cover fixed costs, and we may have to reduce our distributions to shareholders. There is significant competition among commercial properties: Many other commercial properties compete with our properties for tenants. Some of the competing properties may be newer and better located than our properties. Competition in the market areas in which many of our properties are located is significant and has affected our occupancy levels, rental rates and operating expenses. We also expect that new properties will be built in our markets. In addition, we compete with other buyers, many of which are larger than us, for attractive commercial properties. Therefore, we may not be able to grow as rapidly as we would like. We may encounter significant delays and expense in re-letting vacant space, or we may not be able to re-let space at existing rates, in each case resulting in losses of income: When leases expire, we may incur expenses in retrofitting space and we may not be able to re-lease the space on the same terms. Certain leases provide tenants with the right to terminate early if they pay a fee. As of December 31, 2012, our properties generally had lower vacancy rates than the average for the markets in which they are located, and 2,040 leases representing 29.0% of the leased square footage of our total portfolio or 27.7% of annualized rental income are scheduled to expire in 10 2013. While we have estimated our cost of renewing leases that expire in 2013, our estimates could be wrong. If we are unable to re-lease space promptly, if the terms are significantly less favorable than anticipated or if the costs are higher, we may have to reduce our distributions to shareholders. Tenant defaults and bankruptcies may reduce our cash flow and distributions: We may have difficulty collecting from tenants in default, particularly if they declare bankruptcy. This could affect our cash flow and our ability to fund distributions to shareholders. Since many of our tenants are non-rated private companies, this risk may be enhanced. There is inherent uncertainty in a tenant’s ability to continue paying rent if they are in bankruptcy. We may be adversely affected if casualties to our properties are not covered by insurance: We could suffer uninsured losses or losses in excess of our insurance policy limits for occurrences such as earthquakes or hurricanes that adversely affect us or even result in loss of the property. Approximately 39.4% of our properties are located in California and are generally in areas that are subject to risks of earthquake related damage. We might still remain liable on any mortgage debt or other unsatisfied obligations related to that property. The illiquidity of our real estate investments may prevent us from adjusting our portfolio to respond to market changes: There may be delays and difficulties in selling real estate. Therefore, we cannot easily change our portfolio when economic conditions change. Also, REIT tax laws may impose negative consequences if we sell properties held for less than four years. We may be adversely affected by changes in laws: Increases in income and service taxes may reduce our cash flow and ability to make expected distributions to our shareholders. Our properties are also subject to various federal, state and local regulatory requirements, such as state and local fire and safety codes. If we fail to comply with these requirements, governmental authorities could fine us or courts could award damages against us. We believe our properties comply with all significant legal requirements. However, these requirements could change in a way that would reduce our cash flow and ability to make distributions to shareholders. We may incur significant environmental remediation costs: As an owner and operator of real properties, under various federal, state and local environmental laws, we are required to clean up spills or other releases of hazardous or toxic substances on or from our properties. Certain environmental laws impose liability whether or not the owner or buyer knew of, or was responsible for, the presence of the hazardous or toxic substances. In some cases, liability may not be limited to the value of the property. The presence of these substances, or the failure to properly remediate any resulting contamination, whether from environmental or microbial issues, also may adversely affect our ability to sell, lease, operate, or encumber our facilities for purposes of borrowing. the property (not We have conducted preliminary environmental assessments of most of our properties (and conduct these assessments in connection with property acquisitions) to evaluate the environmental condition of, and potential environmental liabilities associated with, our properties. These assessments generally consist of an investigation of environmental conditions at including soil or groundwater sampling or analysis if appropriate), as well as a review of available information regarding the site and publicly available data regarding conditions at other sites in the vicinity. In connection with these property assessments, our operations and recent property acquisitions, we have become aware that prior operations or activities at some properties or from nearby locations have or may have resulted in contamination to the soil or groundwater at these properties. In circumstances where our environmental assessments disclose potential or actual contamination, we may attempt to obtain indemnifications and, in appropriate circumstances, we obtain limited environmental insurance in connection with the properties acquired, but we cannot assure you that such protections will be sufficient to cover actual future liabilities nor that our assessments have identified all such risks. Although we cannot provide any assurance, based on the preliminary environmental assessments, we are not aware of any environmental contamination of our facilities material to our overall business, financial condition or results of operations. There has been an increasing number of claims and litigation against owners and managers of rental properties relating to moisture infiltration, which can result in mold or other property damage. When we receive a complaint concerning moisture infiltration, condensation or mold problems and/or become aware that an air quality concern exists, we implement corrective measures in accordance with guidelines and protocols we have developed with the assistance of outside experts. We seek to work proactively with our tenants to resolve 11 moisture infiltration and mold-related issues, subject to our contractual limitations on liability for such claims. However, we can give no assurance that material legal claims relating to moisture infiltration and the presence of, or exposure to, mold will not arise in the future. Property taxes can increase and cause a decline in yields on investments: Each of our properties is subject to real property taxes, which could increase in the future as property tax rates change and as our properties are assessed or reassessed by tax authorities. Recent local government shortfalls in tax revenue may cause pressure to increase tax rates or assessment levels or impose new taxes. Such increases could adversely impact our profitability. We must comply with the Americans with Disabilities Act and fire and safety regulations, which can require significant expenditures: All our properties must comply with the Americans with Disabilities Act and with related regulations (the “ADA”). The ADA has separate compliance requirements for “public accommodations” and “commercial facilities,” but generally requires that buildings be made accessible to persons with disabilities. Various state laws impose similar requirements. A failure to comply with the ADA or similar state laws could lead to government imposed fines on us and/or litigation, which could also involve an award of damages to individuals affected by the non-compliance. In addition, we must operate our properties in compliance with numerous local fire and safety regulations, building codes, and other land use regulations. Compliance with these requirements can require us to spend substantial amounts of money, which would reduce cash otherwise available for distribution to shareholders. Failure to comply with these requirements could also affect the marketability of our real estate facilities. We incur liability from tenant and employment-related claims: From time to time we have to make monetary settlements or defend actions or arbitration to resolve tenant or employment-related claims and disputes. Global economic conditions adversely affect our business, financial condition, growth and access to capital. There continues to be global economic uncertainty, elevated levels of unemployment, reduced levels of economic activity, and it is uncertain as to when economic conditions will improve. These negative economic conditions in the markets where we operate facilities, and other events or factors that adversely affect demand for commercial real estate, could continue to adversely affect our business. To the extent that turmoil in the financial markets returns or intensifies, it has the potential to materially affect the value of our properties, the availability or the terms of financing and may impact the ability of our customers to enter into new leasing transactions or satisfy rental payments under existing leases. The uncertainty and pace of an economic recovery could also affect our operating results and financial condition as follows: Debt and Equity Markets: Our results of operations and share price are sensitive to volatility in the credit markets. The commercial real estate debt markets have experienced volatility as a result of various factors, including the tightening of underwriting standards by lenders and credit rating agencies. This has resulted in lenders increasing the cost for debt financing. Should the overall cost of borrowings increase, either by increases in the index rates or by increases in lender spreads, we will need to factor such increases into the economics of our acquisitions. In addition, the state of the debt markets could have an effect on the overall amount of capital being invested in real estate, which may result in price or value decreases of real estate assets and affect our ability to raise capital. Our ability to issue preferred shares or obtain other sources of capital, such as borrowing, has been in the past, and may in the future, be adversely affected by challenging credit market conditions. The issuance of perpetual preferred securities historically has been a significant source of capital to grow our business. We believe that we have sufficient working capital and capacity under our credit facilities and our retained cash flow from operations to continue to operate our business as usual and meet our current obligations. However, if we were unable to issue preferred shares or borrow at reasonable rates, that could limit the earnings growth that might otherwise result from the acquisition and development of real estate facilities. Valuations: Market volatility has made the valuation of our properties more difficult. There may be significant uncertainty in the valuation, or in the stability of the value, of our properties, which could result in a substantial decrease in the value of our properties. As a result, we may not be able to recover the carrying amount of our properties, which may require us to recognize an impairment charge in earnings. 12 The acquisition of existing properties is a significant component of our long-term growth strategy, and acquisitions of existing properties are subject to risks that may adversely affect our growth and financial results. We acquire existing properties, either in individual transactions or portfolios offered by other commercial real estate owners. In addition to the general risks related to real estate described above, we are also subject to the following risks which may jeopardize our realization of benefits from acquisitions. Any failure to manage acquisitions and other significant transactions to achieve anticipated results and to successfully integrate acquired operations into our existing business could negatively impact our financial results: To fully realize anticipated earnings from an acquisition, we must successfully integrate the property into our operating platform. Failures or unexpected circumstances in the integration process, such as a failure to maintain existing relationships with tenants and employees due to changes in processes, standards, or compensation arrangements, or circumstances we did not detect during due diligence, could jeopardize realization of the anticipated earnings. During 2012, we acquired 1.2 million square feet for an aggregate purchase price of $52.5 million. We continue to seek to acquire and develop multi-tenant flex, industrial and office properties where they meet our criteria, all of which we believe will enhance our future financial performance and the value of our portfolio. Our belief, however, is subject to risks, uncertainties and other factors, many of which are forward-looking and are uncertain in nature or are beyond our control, including the risks that our acquisitions and developments may not perform as expected, that we may be unable to quickly integrate new acquisitions and developments into our existing operations, and that any costs to develop projects or redevelop acquired properties may exceed estimates. As of December 31, 2012, the aggregate occupancy of the assets acquired in 2012 was 57.4%. If we are unable to lease the vacant square footage of these properties in a reasonable period of time, we may not be able to achieve our objective of enhancing value. Further, we face significant competition for suitable acquisition properties from other real estate investors, including other publicly traded real estate investment trusts and private institutional investors. As a result, we may be unable to acquire additional properties we desire or the purchase price for desirable properties may be significantly increased. In addition, some of these properties may have unknown characteristics or deficiencies or may not complement our portfolio of existing properties. We may also finance future acquisitions and developments through a combination of borrowings, proceeds from equity or debt offerings by us or the Operating Partnership, and proceeds from property divestitures. These financing options may not be available when desired or required or may be more costly than anticipated, which could adversely affect our cash flow. Real property development is subject to a number of risks, including construction delays, complications in obtaining necessary zoning, occupancy and other governmental permits, cost overruns, financing risks, and the possible inability to meet expected occupancy and rent levels. If any of these problems occur, development costs for a project may increase, and there may be costs incurred for projects that are not completed. As a result of the foregoing, some properties may be worth less or may generate less revenue than, or simply not perform as well as, we believed at the time of acquisition or development, negatively affecting our operating results. Any of the foregoing risks could adversely affect our financial condition, operating results and cash flow, and our ability to pay dividends on, and the market price of, our stock. In addition, we may be unable to successfully integrate and effectively manage the properties we do acquire and develop, which could adversely affect our results of operations. Acquired properties are subject to property tax reappraisals which may increase our property tax expense: Facilities that we acquire are subject to property tax reappraisal which can result in substantial increases to the ongoing property taxes paid by the seller. The reappraisal process is subject to judgment of governmental agencies regarding estimated real estate values and other factors, and as a result there is a significant degree of uncertainty in estimating the property tax expense of an acquired property. In connection with future or recent acquisitions of properties, if our estimates of property taxes following reappraisal are too low, we may not realize anticipated earnings from an acquisition. 13 We would incur adverse tax consequences if we fail to qualify as a REIT. Our cash flow would be reduced if we fail to qualify as a REIT: While we believe that we have qualified since 1990 to be taxed as a REIT, and will continue to be so qualified, we cannot be certain. To continue to qualify as a REIT, we need to satisfy certain requirements under the federal income tax laws relating to our income, assets, distributions to shareholders and shareholder base. In this regard, the share ownership limits in our articles of incorporation do not necessarily ensure that our shareholder base is sufficiently diverse for us to qualify as a REIT. For any year we fail to qualify as a REIT, we would be taxed at regular corporate tax rates on our taxable income unless certain relief provisions apply. Taxes would reduce our cash available for distributions to shareholders or for reinvestment, which could adversely affect us and our shareholders. Also we would not be allowed to elect REIT status for five years after we fail to qualify unless certain relief provisions apply. We may need to borrow funds to meet our REIT distribution requirements: To qualify as a REIT, we must generally distribute to our shareholders 90% of our taxable income. Our income consists primarily of our share of our Operating Partnership’s income. We intend to make sufficient distributions to qualify as a REIT and otherwise avoid corporate tax. However, differences in timing between income and expenses and the need to make nondeductible expenditures such as capital improvements and principal payments on debt could force us to borrow funds to make necessary shareholder distributions. PS has significant influence over us. At December 31, 2012, PS owned 23.9% of the outstanding shares of the Company’s common stock and 23.1% of the outstanding 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 partnership units, PS would own 41.5% of the outstanding shares of the Company’s common stock. In addition, the PS Business Parks name and logo is 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. Ronald L. Havner, Jr., the Company’s chairman, is also Chairman of the Board, Chief Executive Officer and President of PS. Consequently, PS has the ability to significantly influence all matters submitted to a vote of our shareholders, including electing directors, changing our articles of incorporation, dissolving and approving other extraordinary transactions such as mergers, and all matters requiring the consent of the limited partners of the Operating Partnership. PS’s interest in such matters may differ from other shareholders. In addition, PS’s ownership may make it more difficult for another party to take over our Company without PS’s approval. Provisions in our organizational documents may prevent changes in control. Our articles generally prohibit any person from owning more than 7% of our shares: Our articles of incorporation restrict the number of shares that may be owned by any other person, and the partnership agreement of our Operating Partnership contains an anti-takeover provision. No shareholder (other than PS and certain other specified shareholders) may own more than 7% of the outstanding shares of our common stock, unless our board of directors waives this limitation. We imposed this limitation to avoid, to the extent possible, a concentration of ownership that might jeopardize our ability to qualify as a REIT. This limitation, however, also makes a change of control much more difficult (if not impossible) even if it may be favorable to our public shareholders. These provisions will prevent future takeover attempts not supported by PS even if a majority of our public shareholders consider it to be in their best interests as they would receive a premium for their shares over market value or for other reasons. Our board can set the terms of certain securities without shareholder approval: Our board of directors is authorized, without shareholder approval, to issue up to 50.0 million shares of preferred stock and up to 100.0 million shares of equity stock, in each case in one or more series. Our board has the right to set the terms of each of these series of stock. Consequently, the board could set the terms of a series of stock that could make it difficult (if not impossible) for another party to take over our Company even if it might be favorable to our public shareholders. Our articles of incorporation also contain other provisions that could have the same effect. We can also cause our Operating Partnership to issue additional interests for cash or in exchange for property. 14 The partnership agreement of our Operating Partnership restricts mergers: The partnership agreement of our Operating Partnership generally provides that we may not merge or engage in a similar transaction unless the limited partners of our Operating Partnership are entitled to receive the same proportionate payments as our shareholders. In addition, we have agreed not to merge unless the merger would have been approved had the limited partners been able to vote together with our shareholders, which has the effect of increasing PS’s influence over us due to PS’s ownership of operating partnership units. These provisions may make it more difficult for us to merge with another entity. Our Operating Partnership poses additional risks to us. Limited partners of our Operating Partnership, including PS, have the right to vote on certain changes to the partnership agreement. They may vote in a way that is against the interests of our shareholders. Also, as general partner of our Operating Partnership, we are required to protect the interests of the limited partners of the Operating Partnership. The interests of the limited partners and of our shareholders may differ. We depend on external sources of capital to grow our Company. We are generally required under the Internal Revenue Code to distribute at least 90% of our taxable income. Because of this distribution requirement, we may not be able to fund future capital needs, including any necessary building and tenant improvements, from operating cash flow. Consequently, we may need to rely on third-party sources of capital to fund our capital needs. We may not be able to obtain the financing on favorable terms or at all. Access to third-party sources of capital depends, in part, on general market conditions, the market’s perception of our growth potential, our current and expected future earnings, our cash flow, and the market price per share of our common stock. If we cannot obtain capital from third-party sources, we may not be able to acquire properties when strategic opportunities exist, satisfy any debt service obligations, or make cash distributions to shareholders. We are subject to laws and governmental regulations and actions that affect our operating results and financial condition. Our business is subject to regulation under a wide variety of U.S. federal, state and local laws, regulations and policies including those imposed by the SEC, the Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act and New York Stock Exchange, as well as applicable labor laws. Although we have policies and procedures designed to comply with applicable laws and regulations, failure to comply with the various laws and regulations may result in civil and criminal liability, fines and penalties, increased costs of compliance and restatement of our financial statements. There can also be no assurance that, in response to current economic conditions or the current political environment or otherwise, laws and regulations will not be implemented or changed in ways that adversely affect our operating results and financial condition, such as recently adopted legislation that expands health care coverage costs or facilitates union activity or federal legislative proposals to otherwise increase operating costs. Terrorist attacks and the possibility of wider armed conflict may have an adverse impact on our business and operating results and could decrease the value of our assets. Terrorist attacks and other acts of violence or war could have a material adverse impact on our business and operating results. There can be no assurance that there will not be further terrorist attacks against the U.S. Attacks or armed conflicts that directly impact one or more of our properties could significantly affect our ability to operate those properties and thereby impair our operating results. Further, we may not have insurance coverage for losses caused by a terrorist attack. Such insurance may not be available, or if it is available and we decide to obtain such terrorist coverage, the cost for the insurance may be significant in relationship to the risk overall. In addition, the adverse effects that such violent acts and threats of future attacks could have on the U.S. economy could similarly have a material adverse effect on our business and results of operations. Finally, further terrorist acts could cause the U.S. to enter into a wider armed conflict, which could further impact our business and operating results. 15 Developments in California may have an adverse impact on our business and financial results. We are headquartered in, and approximately 39.4% of our properties are located in California, which like many other state and local jurisdictions is facing severe budgetary problems and deficits. Actions have been and may continue to be taken in response to these problems, such as increases in property taxes, changes to sales taxes or other governmental efforts to raise revenues could adversely impact our business and results of operations. ITEM 1B. UNRESOLVED STAFF COMMENTS None. 16 ITEM 2. PROPERTIES As of December 31, 2012, the Company owned 102 business parks consisting of a geographically diverse portfolio of 28.3 million rentable square feet of commercial real estate which consists of 14.9 million square feet of flex space, 8.4 million square feet of industrial space and 5.0 million square feet of office space concentrated primarily in eight states consisting of California, Virginia, Florida, Texas, Maryland, Washington, Oregon and Arizona. The weighted average occupancy rate throughout 2012 was 89.0% and the realized rent per square foot was $14.05. The following table reflects the geographical diversification of the 102 business parks owned by the Company as of December 31, 2012, the type of the rentable square footage and the weighted average occupancy rates throughout 2012 (except as set forth below, all of the properties are held in fee simple interest) (in thousands, except number of business parks): State California (1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

For more information, see Note 6 to the consolidated financial statements. (2) The Company owns two properties that are subject to ground leases in Las Colinas, Texas, expiring in 2019 and 2020, each with one 10 year extension option. We currently anticipate that each of the properties listed above will continue to be used for its current purpose. Competition exists in each of the market areas in which these properties are located. The Company has no plans to change the current use of its properties. The Company typically renovates its properties in connection with the re-leasing of space to tenants and expects that it will pay the costs of such tenants will default on leases and declare renovations from rental bankruptcy. Management believes these risks are mitigated through the Company’s geographic diversity and diverse tenant base. income. The Company has risks that The Company evaluates the performance of its business parks primarily based on net operating income (“NOI”). NOI is defined by the Company as rental income as defined by GAAP less cost of operations as defined by GAAP, excluding depreciation and amortization. The Company uses NOI and its components as a measurement of the performance of its commercial real estate. Management believes that these financial measures provide them, as well as the investor, the most consistent measurement on a comparative basis of the performance of the commercial real estate and its contribution to the value of the Company. Depreciation and amortization have been excluded from NOI as they are generally not used in determining the value of commercial real estate by management or the investment community. Depreciation and amortization are generally not used in determining value as they consider the historical costs of an asset compared to its current value; therefore, to understand the effect of the assets’ historical cost on the Company’s results, investors should look at GAAP financial measures, such as total operating costs including depreciation and amortization. The Company’s calculation of NOI may not be comparable to those of other companies and should not be used as an alternative to measures of performance calculated in accordance with GAAP. As part of the table below, we have reconciled total NOI to income from continuing operations, which we consider the most directly comparable financial measure calculated in accordance with GAAP. The following information illustrates rental income, cost of operations and NOI generated by the Company’s total portfolio in 2012, 2011 and 2010 by state and by property classifications. As a result of acquisitions and dispositions, certain properties were not held for the full year. 17 f o s e r u s a e m o t e v i t a n r e t l a n a s a d e s u e b t o n d l u o h s d n a s e i n a p m o c r e h t o f o e s o h t o t e l b a r a p m o c e b t o n y a m I O N f o n o i t a l u c l a c s ’ y n a p m o C e h T n i ( P A A G n o d e s a b s t n u o m a e l b a r a p m o c t s o m e h t o t I O N f o n o i t a i l i c n o c e r a e d u l c n i o s l a w o l e b s e l b a t e h T .

The White Paper defines FFO as net income, computed in accordance with GAAP, before depreciation, amortization, gains or losses on asset dispositions, net income allocable to noncontrolling interests — common units, net income allocable to restricted stock unit holders, impairment charges and nonrecurring items. FFO should be analyzed in conjunction with net income. However, FFO should not be viewed as a substitute for net income as a measure of operating performance or liquidity as it does not reflect depreciation and amortization costs or the level of capital expenditure and leasing costs necessary to maintain the operating performance of the Company’s properties, which are significant economic costs and could materially impact the Company’s results of operations. Other REITs may use different methods for calculating FFO and, accordingly, the Company’s FFO may not be comparable to that of other real estate companies. See Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Funds from Operations,” for a reconciliation of FFO and net income allocable to common shareholders and for information on why the Company presents FFO. 22 ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion and analysis of the results of operations and financial condition should be read in conjunction with the selected financial data and the Company’s consolidated financial statements and notes thereto included elsewhere in the Form 10-K. Overview As of December 31, 2012, the Company owned and operated 28.3 million rentable square feet of multi- tenant flex, industrial and office properties located in eight states. The Company focuses on increasing profitability and cash flow aimed at maximizing shareholder value. The Company strives to maintain high occupancy levels while increasing rental rates when market conditions allow, although the Company may decrease rental rates in markets where conditions require. The Company also acquires properties it believes will create long-term value, and from time to time disposes of properties which no longer fit within the Company’s strategic objectives or in situations where the Company believes it can optimize cash proceeds. Operating results are driven primarily by income from rental operations and are therefore substantially influenced by rental demand for space within our properties and our markets, which impacts occupancy and rental rates. During 2012, the Company executed leases comprising 8.0 million square feet of space including 4.4 million square feet of renewals of existing leases and 3.6 million square feet of new leases. Overall, the Company experienced a decrease in rental rates when comparing new rental rates to outgoing rental rates of 6.2%. See further discussion of operating results below. Critical Accounting Policies and Estimates: Our accounting policies are described in Note 2 to the consolidated financial statements included in this Form 10-K. 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 we discuss below. Revenue Recognition: The Company must meet four basic criteria before revenue can be recognized: persuasive evidence of an arrangement exists; the delivery has occurred or services rendered; the fee is fixed or determinable; and collectability is reasonably assured. All leases are classified as operating leases. Rental income is recognized on a straight-line basis over the terms of the leases. Straight-line rent is recognized for all tenants with contractual fixed increases in rent that are not included on the Company’s credit watch list. Deferred rent receivable represents rental revenue recognized on a straight-line basis in excess of billed rents. Reimbursements from tenants for real estate taxes and other recoverable operating expenses are recognized as rental income in the period the applicable costs are incurred. Property management fees are recognized in the period earned. Property Acquisitions: The Company records the purchase price of acquired properties to land, buildings and improvements and intangible assets and liabilities associated with in-place leases (including tenant improvements, unamortized lease commissions, value of above-market and below-market leases, acquired in-place lease values, and tenant relationships, if any) based on their respective estimated fair values. Acquisition related costs are expensed as incurred. In determining the fair value of the tangible assets of the acquired properties, management considers the value of the properties as if vacant as of the acquisition date. Management must make significant assumptions in determining the value of assets acquired and liabilities assumed. Using different assumptions in the recording of the purchase cost of the acquired properties would affect the timing of recognition of the related revenue and expenses. Amounts recorded to land are derived from comparable sales of land within the same region. Amounts recorded to buildings and improvements, tenant improvements and unamortized lease commissions are based on current market replacement costs and other market rate information. 23 The value recorded to the above-market or below-market in-place lease values of acquired properties is determined based upon the present value (using a discount rate which reflects the risks associated with the acquired leases) of the difference between (i) the contractual rents to be paid pursuant to the in-place leases, and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease. The amounts recorded to above-market or below-market leases are included in other assets or other liabilities in the accompanying consolidated balance sheets and are amortized on a straight-line basis as an increase or reduction of rental income over the remaining non-cancelable term of the respective leases. Allowance for Doubtful Accounts: Rental revenue from our tenants is our principal source of revenue. We monitor the collectability of our receivable balances including the deferred rent receivable on an ongoing basis. Based on these reviews, we maintain an allowance for doubtful accounts for estimated losses resulting from the possible inability of our tenants to make required rent payments to us. Tenant receivables and deferred rent receivables are carried net of the allowances for uncollectible tenant receivables and deferred rent. As discussed below, determination of the adequacy of these allowances requires significant judgments and estimates. Our estimate of the required allowance is subject to revision as the factors discussed below change and is sensitive to the effect of economic and market conditions on our tenants. 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. Determination of the adequacy of the allowance for uncollectible current tenant receivables is performed using a methodology that incorporates specific identification, aging analysis, an overall evaluation of the historical loss trends and the current economic and business environment. The specific identification methodology relies on factors such as the age and nature of the receivables, the payment history and financial condition of the tenant, the assessment of the tenant’s ability to meet its lease obligations, and the status of negotiations of any disputes with the tenant. The allowance also includes a reserve based on loss trends not associated with any specific tenant. This reserve as well as the specific historical identification reserve is reevaluated quarterly based on economic conditions and the current business environment. 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. Given the long-term nature of these types of receivables, determination of the adequacy of the allowance for unbilled deferred rent receivable is based primarily on historical loss experience. Management evaluates the allowance for unbilled deferred rent receivable using a specific identification methodology for significant tenants designed to assess their financial condition and ability to meet their lease obligations. Impairment of Long-Lived Assets: The Company evaluates a property for potential impairment whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. On a quarterly basis, we evaluate our entire portfolio for impairment based on current operating information. In the event that these periodic assessments reflect that the carrying amount of a property exceeds the sum of the undiscounted cash flows (excluding interest) that are expected to result from the use and eventual disposition of the property, the Company would recognize an impairment loss to the extent the carrying amount exceeded the estimated fair value of the property. The estimation of expected future net cash flows is inherently uncertain and relies on subjective assumptions dependent upon future and current market conditions and events that affect the ultimate value of the property. Management must make assumptions related to the property such as future rental rates, tenant allowances, operating expenditures, property taxes, capital improvements, occupancy levels and the estimated proceeds generated from the future sale of the property. These assumptions could differ materially from actual results in future periods. Our intent to hold properties over the long-term directly decreases the likelihood of recording an impairment loss. If our strategy changes or if market conditions otherwise dictate an earlier sale date, an impairment loss could be recognized, and such loss could be material. 24 Depreciation: We compute depreciation on our buildings and improvements using the straight-line method based on estimated useful lives generally ranging from five to 30 years. A significant portion of the acquisition cost of each property is recorded to building and building components. The recording of the acquisition cost to building and building components, as well as the determination of their useful lives, are based on estimates. If we do not appropriately record to these components or we incorrectly estimate the useful lives of these components, our computation of depreciation expense may not appropriately reflect the actual impact of these costs over future periods, which will affect net income. In addition, the net book value of real estate assets could be overstated or understated. The statement of cash flows, however, would not be affected. Accruals of Operating Expenses: The Company accrues for property tax expenses, performance bonuses and other operating expenses each quarter based on historical trends and anticipated disbursements. If these estimates are incorrect, the timing and amount of expense recognized will be affected. Accruals for Contingencies: The Company is exposed to business and legal liability risks with respect to events that may have occurred, but in accordance with GAAP has not accrued for such potential liabilities because the loss is either not probable or not estimable. Future events could result in such potential losses becoming probable and estimable, which could have a material adverse impact on our financial condition or results of operations. Effect of Economic Conditions on the Company’s Operations: During 2012, while certain markets reflected signs of improved occupancy, overall the Company continued to experience decreases in new rental rates over expiring rental rates on executed leases as a result of a slow recovery of economic conditions combined with continued competitive conditions within the commercial real estate environment. The rate of decrease eased from 8.3% for the year ended December 31, 2011 to 6.2% for the year ended December 31, 2012. Although it is uncertain what impact economic conditions and competition will have on the Company’s future ability to maintain existing occupancy levels and rental rates, management believes that the decrease in rental rates on lease transactions could negatively impact rental income for 2013. Current and future economic conditions may continue to have a significant impact on the Company, potentially resulting in further reductions in occupancy and rental rates. The Company historically has experienced a low level of write-offs of uncollectable rents, however, there is inherent uncertainty in a tenant’s ability to continue paying rent and meet their full lease obligation.

From time to time, tenants contact us, requesting early termination of their lease, a reduction in space under lease, or rent deferment or abatement. At this time, the Company cannot anticipate what impact, if any, the ultimate outcome of these discussions will have on our future operating results. Company Performance and Effect of Economic Conditions on Primary Markets: The Company’s operations are substantially concentrated in 10 regions. During the year ended December 31, 2012, initial rental rates on new and renewed leases within the Company’s overall portfolio decreased 6.2% over expiring rents, an improvement from a decline of 8.3% for the year ended December 31, 2011. The Company’s Same Park (defined below) occupancy rate at December 31, 2012 was 92.7%, compared to 92.6% at December 31, 2011. The 25 Company’s overall occupancy rate at December 31, 2012 was 89.5%, compared to 88.9% at December 30, 2011. Each of the 10 regions in which the Company owns assets is subject to its own unique market influences. See “Supplemental Property Data and Trends” below for more information on regional operating data. Growth of the Company’s Operations from Acquisitions and Dispositions of Properties: The Company is focused on maximizing cash flow from its existing portfolio of properties by looking for opportunities to expand its presence in existing and new markets through strategic acquisitions. The Company may from time to time dispose of non-strategic assets that do not meet this criterion. The Company has historically maintained a low- leverage-level approach intended to provide the Company with the greatest level of flexibility for future growth. On December 19, 2012, the Company acquired three multi-tenant flex buildings in Austin, Texas, aggregating 226,000 square feet, for a purchase price of $14.9 million. In connection with this purchase, the Company received a $592,000 credit for committed tenant improvements and lease commissions. On July 24, 2012, the Company acquired a 958,000 square foot industrial park consisting of eight single-story buildings located in Kent Valley, Washington, for a purchase price of $37.6 million. As of December 31, 2012, the blended occupancy rate of the 11 assets acquired from 2010 through 2012 was 82.6% compared to a blended occupancy rate of 75.1% at the time of acquisition. As of December 31, 2012, the Company had 1.6 million square feet of vacancy spread over these 11 acquisitions which we believe provides the Company with considerable opportunity to generate additional rental income given that the Company’s Same Park assets in these same submarkets have a weighted occupancy of 94.9% at December 31, 2012.

In October, 2012, the Company completed the sale of Quail Valley Business Park, a 66,000 square foot flex park in Houston, Texas, for a gross sales price of $2.3 million, resulting in a net gain of $935,000. In August, 2011, the Company completed the sale of Westchase Corporate Park, a 177,000 square foot flex park consisting of 13 buildings in Houston, Texas, for a gross sales price of $9.8 million, resulting in a net gain of $2.7 million. In January, 2010, the Company completed the sale of a 131,000 square foot office building located in Houston, Texas, for a gross sales price of $10.0 million, resulting in a net gain of $5.2 million. Scheduled Lease Expirations: In addition to the 3.0 million square feet, or 10.5%, of space available in our total portfolio as of December 31, 2012, 2,040 leases representing 29.0% of the leased square footage of our total portfolio or 27.7% of annualized rental income are scheduled to expire in 2013. Our ability to re-lease available space will depend upon market conditions in the specific submarkets in which our properties are located. We cannot predict with certainty the rate at which expiring leases will be re-leased. 26 Impact of Inflation: Although inflation has not been significant in recent years, it remains a potential factor in our economy, and the Company continues to seek ways to mitigate its potential impact. A substantial portion of the Company’s leases require tenants to pay operating expenses, including real estate taxes, utilities, and insurance, as well as increases in common area expenses, partially reducing the Company’s exposure to inflation.

Comparison of 2012 to 2011 Results of Operations: Net income for the year ended December 31, 2012 was $95.4 million compared to $102.6 million for the year ended December 31, 2011. Net income allocable to common shareholders for the year ended December 31, 2012 was $19.8 million compared to $52.2 million for the year ended December 31, 2011. Net income per common share on a diluted basis was $0.81 for the year ended December 31, 2012 compared to $2.12 for the year ended December 31, 2011 (based on weighted average diluted common shares outstanding of 24,323,000 and 24,599,000, respectively). The decrease in net income allocable to common shareholders was primarily due to the net impact of non-cash distributions and gains relating to preferred equity transactions and increases in depreciation and amortization, interest expense and preferred equity distributions, partially offset by an increase in net operating income. 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 Company defines Same Park to include all operating properties owned or acquired prior to January 1, 2010. Operating properties that the Company acquired subsequent to January 1, 2010 are referred to as “Non-Same Park.” For the year ended December 31, 2012 and 2011, the Same Park facilities constitute 19.2 million rentable square feet, representing 67.7% of the 28.3 million square feet in the Company’s portfolio as of December 31, 2012. 28 The following table presents the operating results of the Company’s properties for the years ended December 31, 2012 and 2011 in addition to other income and expense items affecting income from continuing operations (in thousands, except per square foot data): For The Years Ended December 31, 2012 2011 Change Rental income: . . . . . . . . . . . . . . . . . . . . . .

Includes a lease buyout payment of $1.8 million recorded in the fourth quarter of 2012 associated with a 39,000 square foot lease in Virginia which terminated as of December 25, 2012 and a lease buyout payment of $2.9 million recorded in the third quarter of 2011 associated with a 53,000 square foot lease in Maryland which terminated as of August 31, 2011. Excluding the lease buyout payments noted above, rental income from the Same Park portfolio increased slightly, while net operating income from the Same Park portfolio increased 0.7% for the year ended December 31, 2012 over 2011. (2) Net operating income (“NOI”) is an important measurement in the commercial real estate industry for determining the value of the real estate generating the NOI. See “Item 2. Properties” above for more information on 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 in accordance with GAAP. (3) Same Park gross margin is computed by dividing Same Park NOI by Same Park rental income excluding the lease buyout payments recorded in 2012 and 2011 noted above. (4) Same Park realized rent per square foot represents the Same Park rental income earned per occupied square foot excluding the lease buyout payments recorded in 2012 and 2011 noted above. 29 Supplemental Property Data and Trends: NOI from continuing operations is summarized for the years ended December 31, 2012 and 2011 by region below. See “Item 2. Properties” 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. The following table summarizes the Same Park operating results by region for the years ended December 31, 2012 and 2011. In addition, the table reflects the comparative impact on the overall rental income, cost of operations and NOI from properties that have been acquired since January 1, 2010, and the impact of such is included in Non-Same Park facilities in the table below.

Including the lease buyout payments, rental income increased $49.1 million from $297.5 million for the year ended December 31, 2011 to $346.5 million for the year ended December 31, 2012 as a result of a $50.1 million increase in rental income from Non-Same Park facilities, partially offset by a $994,000 decrease in rental income from the Same Park portfolio. Facility Management Fees: Facility management fees, derived from PS, account for a small portion of the Company’s net income. During the year ended December 31, 2012, $649,000 of revenue was recognized from facility management fees compared to $684,000 for the year ended December 31, 2011. Cost of Operations: Cost of operations for the year ended December 31, 2012 was $114.1 million compared to $99.9 million for the year ended December 31, 2011, an increase of $14.2 million, or 14.2% as a result of an increase in cost of operations from Non-Same Park facilities of $15.3 million, partially offset by a $1.1 million decrease from the Same Park portfolio. The decrease in Same Park cost of operations was driven by decreases in repairs and maintenance and utility costs, partially offset by increases in payroll and benefit and insurance costs. Depreciation and Amortization Expense: Depreciation and amortization expense was $109.4 million for the year ended December 31, 2012 compared to $84.4 million for the year ended December 31, 2011. The increase was primarily due to depreciation relating to 2011 property acquisitions. General and Administrative Expenses: For the year ended December 31, 2012, general and administrative expenses decreased $117,000, or 1.3%, over 2011 as a result of a decrease in acquisition transactions costs due to lower volume of acquisitions. Excluding the acquisition transaction costs, general and administrative expenses increased $2.6 million, or 43.6%, compared to 2011 as a result of an increase in non-cash stock compensation expense from the amortization of a long-term incentive plan which commenced January, 2012. Interest Expense: Interest expense was $20.6 million for the year ended December 31, 2012 compared to $5.5 million for the year ended December 31, 2011. The increase was primarily attributable to interest expense on the term loan and mortgage note assumption related to the Northern California Portfolio acquisition in December, 2011 combined with borrowings on the Credit Facility (described below). Gain on Sale of Real Estate Facility: Included in total discontinued operations is the gain on the sale of Quail Valley Business Park, a 66,000 square foot flex park in Houston, Texas, for a gross sales price of $2.3 million, resulting in a net gain of $935,000 during October, 2012. 31 In August, 2011, the Company completed the sale of Westchase Corporate Park, a 177,000 square foot flex park consisting of 13 buildings in Houston, Texas, for a gross sales price of $9.8 million, resulting in a net gain of $2.7 million. Net Income Allocable to Noncontrolling Interests: Net income allocable to noncontrolling interests reflects the net income allocable to equity interests in the Operating Partnership that are not owned by the Company. Net income allocable to noncontrolling interests was $6.3 million of allocated income ($323,000 allocated to preferred unit holders and $6.0 million of income allocated to common unit holders) for the year ended December 31, 2012 compared to $8.6 million ($7.0 million of loss allocated to preferred unit holders and $15.5 million allocated to common unit holders) for the year ended December 31, 2011. Included in net income allocable to noncontrolling interests for the year ended December 31, 2011 was a $7.4 million loss allocated to preferred unit holders resulting from the repurchase by the Company of preferred units at an amount less than the carrying value, partially offset with $1.7 million of income allocated to common unit holders due to the net gain on the repurchases of preferred units. The decrease in net income allocable to noncontrolling interests for the year was primarily due to the net impact of non-cash distributions and gain relating to preferred equity transactions and increases in depreciation and amortization, interest expense and preferred equity distributions, partially offset by an increase in net operating income. Comparison of 2011 to 2010 Results of Operations: Net income for the year ended December 31, 2011 was $102.6 million compared to $102.0 million for the year ended December 31, 2010. Net income allocable to common shareholders for the year ended December 31, 2011 was $52.2 million compared to $39.0 million for the year ended December 31, 2010. Net income per common share on a diluted basis was $2.12 for the year ended December 31, 2011 compared to $1.58 for the year ended December 31, 2010 (based on weighted average diluted common shares outstanding of 24,599,000 and 24,687,000, respectively). The increase in net income allocable to common shareholders was primarily a result of an increase in net operating income and lower distributions resulting from the reduction of preferred equity outstanding, partially offset by the change in gain on the sale of a real estate facility combined with increases in interest and depreciation expense primarily related to property acquisitions. For the years ended December 31, 2011 and 2010, the Same Park facilities constitute 19.2 million rentable square feet, representing 70.8% of the 27.1 million square feet in the Company’s portfolio as of December 31, 2011. 32 The following table presents the operating results of the Company’s properties for the years ended December 31, 2011 and 2010 in addition to other income and expense items affecting income from continuing operations (in thousands, except per square foot data): For The Years Ended December 31, 2011 2010 Change Rental income: Same Park (19.2 million rentable square feet) (1) . . . . . . . . . . . . . . . . . . . . . . .

Include a lease buyout payment of $2.9 million recorded in the third quarter of 2011 associated with a 53,000 square foot lease in Maryland which terminated as of August 31, 2011. Excluding the $2.9 million of lease buyout payment noted above, rental income and net operating income from the Same Park portfolio decreased 2.9% and 4.5%, respectively, for the year ended December 31, 2011 over 2010. 2) Net operating income (“NOI”) is an important measurement in the commercial real estate industry for determining the value of the real estate generating the NOI. See “Item 2. Properties” above for more information on 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 in accordance with GAAP. (3) (4) Same Park gross margin is computed by dividing Same Park NOI by Same Park rental income excluding the lease buyout payment recorded in 2011 noted above. Same Park realized rent per square foot represents the Same Park rental income earned per occupied square foot excluding the lease buyout payment recorded in 2011 noted above. Supplemental Property Data and Trends: NOI from continuing operations is summarized for the years ended December 31, 2011 and 2010 by region below. 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. 33 The following table summarizes the Same Park operating results by region for the years ended December 31, 2011 and 2010. In addition, the table reflects the comparative impact on the overall rental income, cost of operations and NOI from properties that have been acquired since January 1, 2010, and the impact of such is included in Non-Same Park facilities in the table below.

Including the lease buyout payment, rental income increased $21.2 million from $276.3 million for the year ended December 31, 2010 to $297.5 million for the year ended December 31, 2011 as a result of a $25.9 million increase in rental income from Non-Same Park facilities, partially offset by a $4.7 million decrease in rental income from the Same Park portfolio. Facility Management Fees: Facility management fees, derived from PS, account for a small portion of the Company’s net income. During the year ended December 31, 2011, $684,000 of revenue was recognized from facility management fees compared to $672,000 for the year ended December 31, 2010. Cost of Operations: Cost of operations for the year ended December 31, 2011 was $99.9 million compared to $89.3 million for the year ended December 31, 2010, an increase of $10.6 million, or 11.8% as a result of increases in cost of operations from Non-Same Park facilities of $10.1 million and Same Park of $421,000. The increase in Same Park cost of operations was due to increases in utility costs and repairs and maintenance costs, partially offset by a decrease in payroll and benefit costs. Depreciation and Amortization Expense: Depreciation and amortization expense was $84.4 million for the year ended December 31, 2011 compared to $78.4 million for the year ended December 31, 2010. The increase was primarily due to depreciation from 2011 and 2010 property acquisitions. General and Administrative Expenses: For the year ended December 31, 2011, general and administrative expenses decreased $615,000, or 6.4%, over 2010 as a result of a decrease in payroll and benefit costs and a reduction in professional fees related to legal fees paid during the first quarter of 2010. Additionally, general and administrative expenses for the year ended December 31, 2011 were further reduced due to a decrease in acquisition transactions costs. The Company incurred and expensed acquisition transaction costs of $3.1 million and $3.3 million for the years ended December 31, 2011 and 2010, respectively. Interest and Other Income: Interest and other income reflect earnings on cash balances in addition to miscellaneous income items. Interest income was $22,000 for the year ended December 31, 2011 compared to $198,000 for the year ended December 31, 2010. The decrease was primarily attributable to lower average cash balances in 2011. Average cash balances and effective interest rates for the year ended December 31, 2011 were $12.7 million and 0.2%, respectively, compared to $111.7 million and 0.2%, respectively, for the year ended December 31, 2010. Interest Expense: Interest expense was $5.5 million for the year ended December 31, 2011 compared to $3.5 million for the year ended December 31, 2010. The increase was primarily attributable to an increase in borrowings on the Credit Facility, interest on the Term Loan and mortgage note assumption related to the Northern California Portfolio acquisition. Gain on Sale of Real Estate Facility: Included in total discontinued operations is the gain on the sale of Westchase Corporate Park, a 177,000 square foot flex park consisting of 13 buildings in Houston, Texas, for a gross sales price of $9.8 million, resulting in a net gain of $2.7 million during August, 2011. In January, 2010, the Company completed the sale of a 131,000 square foot office building located in Houston, Texas, for a gross sales price of $10.0 million, resulting in a net gain of $5.2 million. Net Income Allocable to Noncontrolling Interests: Net income allocable to noncontrolling interests reflects the net income allocable to equity interests in the Operating Partnership that are not owned by the Company. Net income allocable to noncontrolling interests was $8.6 million ($7.0 million of loss allocated to preferred unit holders and $15.5 million of income allocated to common unit holders) for the year ended December 31, 2011 compared to $16.7 million of allocated income ($5.1 million allocated to preferred unit holders and $11.6 million allocated to common unit holders) for the year ended December 31, 2010. Included in net income allocable to noncontrolling interests for the year ended December 31, 2011 was a $7.4 million loss allocated to preferred unit holders resulting from the repurchase by the Company of preferred units at an amount less than the carrying value, partially offset with $1.7 million of income allocated to common unit holders due to the net gain on the 35 repurchases of preferred units. The decrease in net income allocable to noncontrolling interests was a result of a decrease in cash distributions as a result of the preferred equity transactions, partially offset by an increase in net operating income from Non-Same Park facilities. Liquidity and Capital Resources Cash and cash equivalents increased $7.9 million from $5.0 million at December 31, 2011 to $12.9 million at December 31, 2012 for the reasons noted below. Net cash provided by operating activities for the years ended December 31, 2012 and 2011 was $209.1 million and $180.6 million, respectively. The increase of $28.5 million in net cash provided by operating activities for the year ended December 31, 2012 compared to the same period in 2011 was primarily due to an increase in net operating income of $34.9 million. 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 improvements, debt service requirements and distributions to shareholders. Net cash used in investing activities was $105.7 million and $337.1 million for the years ended December 31, 2012 and 2011, respectively. The change was primarily due to a decrease in cash paid of $246.7 million for acquisitions, partially offset by an increase in capital improvements of $8.4 million. The Company paid $51.0 million for the acquisitions in Washington and Texas in 2012 compared to $297.7 million for acquisitions in Virginia, Florida, Texas and California in 2011. Net cash used in financing activities was $95.5 million for the year ended December 31, 2012 compared to net cash provided by financing activities of $156.4 million for the year ended December 31, 2011. The $251.9 million increase in cash used was primarily due to a decrease in borrowings of $402.0 million and an increase in debt repayment of $169.8 million as the Company repaid the balance on its Credit Facility in full, reduced the balance on its Term Loan by $50.0 million and repaid a mortgage note payable of $13.2 million, partially offset with net equity transactions of $324.6 million. As described in Item 1, “Business — Borrowings,” the Company has a $250.0 million credit facility and a $250.0 million term loan. The Company had no balance outstanding on the credit facility at December 31, 2012. The Company had $185.0 million outstanding on the Credit Facility at an interest rate of 1.41% at December 31, 2011. The Company had $200.0 million outstanding on the Term Loan at an interest rate of 1.41% at December 31, 2012 and $250.0 million outstanding at an interest rate of 1.50% at December 31, 2011. The Company’s preferred equity outstanding increased to 26.0% of its market capitalization during the year ended December 31, 2012 primarily due to a decrease in outstanding unsecured debt combined with the issuance of preferred stock in 2012. As of December 31, 2012, the Company had three fixed-rate mortgage notes totaling $268.1 million and an outstanding balance on the Term Loan of $200.0 million, which collectively represented 13.7% of its total market capitalization. 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 at December 31, 2012 multiplied by the closing price of the stock on that date. The weighted average interest rate for the mortgage notes is 5.46% per annum. The Company had 23.0% of its properties, in terms of net book value, encumbered at December 31, 2012. The Company focuses on retaining cash for reinvestment as we believe that this provides the greatest level of financial flexibility. While operating results have been negatively impacted by the slow economic conditions, we believe it is likely that as the economy recovers and operating fundamentals improve, additional increases in distributions to the Company’s common shareholders will be required. Going forward, the Company will continue to monitor its taxable income and the corresponding dividend requirements. Issuance of Preferred Stock: On September 14, 2012, the Company issued $230.0 million or 9.2 million depositary shares, each representing 1/1,000 of a share of the 5.75% Cumulative Preferred Stock, Series U, at $25.00 per depositary share. On May 14, 2012, the Company issued $350.0 million or 14.0 million depositary shares, each representing 1/1,000 of a share of the 6.00% Cumulative Preferred Stock, Series T, at $25.00 per depositary share. 36 On January 18, 2012, the Company issued $230.0 million or 9.2 million depositary shares, each representing 1/1,000 of a share of the 6.45% Cumulative Preferred Stock, Series S, at $25.00 per depositary share.

The Company reported the excess of the redemption amount over the carrying amount of $5.3 million, equal to the original issuance costs, as a reduction of net income allocable to common shareholders and unit holders for the year ended December 31, 2012. On November 8, 2010, the Company completed the redemption of its 7.60% Cumulative Preferred Stock, Series L, at its aggregate par value of $48.4 million. The Company reported the excess of the redemption amount over the carrying amount of $1.6 million, equal to the original issuance costs, as a reduction of net income allocable to common shareholders and unit holders for the year ended December 31, 2010. On May 12, 2010, the Company completed the redemption of its 7.950% Series G Cumulative Redeemable Preferred Units at its aggregate par value of $20.0 million, and on June 7, 2010, the Company completed the redemption of its 7.950% Cumulative Preferred Stock, Series K at its aggregate par value of $54.1 million, in each case, together with accrued dividends. In connection with these redemptions, the Company reported the excess of the redemption amount over the carrying amount of $2.4 million, equal to the original issuance costs, as a reduction of net income allocable to common shareholders and unit holders for the year ended December 31, 2010. Repurchase of Preferred Equity: In February, 2011, the Company paid an aggregate of $39.1 million to repurchase 1,710,000 units of its 7.50% Series J Cumulative Redeemable Preferred Units and 203,400 units of its 6.55% Series Q Cumulative Redeemable Preferred Units for a weighted average purchase price of $20.43 per unit. The aggregate par value of the repurchased preferred units was $47.8 million, which generated a gain of $7.4 million, net of original issuance costs of $1.4 million, which was added to net income allocable to common shareholders and unit holders for the year ended December 31, 2011. Repurchase of Common Stock: The Company’s Board of Directors previously 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 Company defines recurring capital expenditures as those necessary to maintain and operate its commercial real estate at its current economic value. Tenant improvement amounts exclude those amounts reimbursed by the tenant. Nonrecurring capital improvements include property renovations and expenditures related to repositioning acquisitions.

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, among other tests, sources of income, share ownership and certain asset tests. As a REIT, the Company is not taxed on that portion of its taxable income that is distributed to its shareholders provided that at least 90% of its taxable income is distributed to its shareholders prior to the filing of its tax return. 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 38 use its Credit Facility or other forms of debt to facilitate real estate acquisitions or other capital allocations. The Company targets a minimum ratio of FFO to combined fixed charges and preferred distributions of 3.0 to 1.0. Fixed charges include interest expense. Preferred distributions include amounts paid to preferred shareholders and preferred Operating Partnership unit holders. For the year ended December 31, 2012, the FFO to fixed charges and preferred distributions coverage ratio was 3.1 to 1.0, excluding the charge for the issuance costs related to the redemption of preferred equity. Non-GAAP Supplemental Disclosure Measure: Funds from Operations: Management believes that FFO is a useful supplemental measure of the Company’s operating performance. The Company computes FFO in accordance with the White Paper on FFO approved by the Board of Governors of NAREIT. The White Paper defines FFO as net income, computed in accordance with GAAP, before depreciation, amortization, gains or losses on asset dispositions, net income allocable to noncontrolling interests — common units, net income allocable to restricted stock unit holders, impairment charges and nonrecurring items. Management believes that FFO provides a useful measure of the Company’s operating performance and when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, development activities, general and administrative expenses and interest costs, providing a perspective not immediately apparent from net income. FFO should be analyzed in conjunction with net income. However, FFO should not be viewed as a substitute for net income as a measure of operating performance or liquidity as it does not reflect depreciation and amortization costs or the level of capital expenditure and leasing costs necessary to maintain the operating performance of the Company’s properties, which are significant economic costs and could materially affect the Company’s results of operations. Management believes FFO provides useful information to the investment community about the Company’s operating performance when compared to the performance of other real estate companies as FFO is generally recognized as the industry standard for reporting operations of REITs. Other REITs may use different methods for calculating FFO and, accordingly, our FFO may not be comparable to other real estate companies.

FFO allocable to common and dilutive shares decreased $15.3 million for the year ended December 31, 2012, respectively, compared to the same periods in 2011. The decrease was primarily due to the net impact of preferred equity transactions (noted above) and increases in interest expense, preferred equity distributions, partially offset by an increase in net operating income. 39 Related Party Transactions: At December 31, 2012, PS owned 23.9% of the outstanding shares of the Company’s common stock and 23.1% of the outstanding 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 partnership units, PS would own 41.5% of the outstanding shares of the Company’s common stock. Ronald L. Havner, Jr., the Company’s chairman, is also the Chairman of the Board, Chief Executive Officer and President of PS. Gary E. Pruitt, an independent director of the Company is also a trustee of PS. Pursuant to a cost sharing and administrative services agreement, the Company shares costs with PS for certain administrative services. These costs totaled $441,000 in 2012, which were allocated to PS in accordance the Company provides property with a methodology intended to fairly allocate those costs. In addition, management services for properties owned by PS for a management fee of 5% of the gross revenues of such properties in addition to reimbursement of direct costs. These management fee revenues recognized under management contract with PS totaled $649,000 in 2012. 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 $55,000 for the year ended December 31, 2012. On February 9, 2011, the Company entered into an agreement with PS to borrow $121.0 million with a maturity date of August 9, 2011 at an interest rate of LIBOR plus 0.85%. The Company repaid, in full, the note payable to PS upon maturity. Interest expense under this note payable was $664,000 for the year ended December 31, 2011. The PS Business Parks name and logo is 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.

Dividends are paid when and if declared by the Company’s Board of Directors and accumulate if not paid. Shares and units of preferred equity are redeemable by the Company in order to preserve its status as a REIT and are also redeemable five years after issuance. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK To limit the Company’s exposure to market risk, the Company principally finances its operations and growth with permanent equity capital consisting of either common or preferred stock. The Company, from time to time, will use debt financing to facilitate acquisitions. In connection with the Northern California Portfolio acquisition, the Company assumed a $250.0 million mortgage note and obtained a $250.0 million term loan. As a result of the acquisition, the Company’s debt as a percentage of total equity (based on book values) was 29.0% as of December 31, 2012. The Company’s market risk sensitive instruments include mortgage notes of $268.1 million and the outstanding balance on the Term Loan of $200.0 million as of December 31, 2012. All of the Company’s mortgage notes bear interest at fixed rates with a weighted average fixed rate of 5.46% at December 31, 2012. The Term Loan bears interest at variable rates which is currently LIBOR plus 1.20%.

CONTROLS AND PROCEDURES Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures The Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of December 31, 2012. 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 December 31, 2012, the Company’s Chief Executive Officer and Chief Financial Officer concluded that, as of such date, the Company’s disclosure controls and procedures were effective at the reasonable assurance level. Management’s Report on Internal Control over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control-Integrated Framework issued by the Committee on Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control-Integrated Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2012. The effectiveness of the Company’s internal control over financial reporting as of December 31, 2012 has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which is included herein. Changes in Internal Control Over Financial Reporting There have not been any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fourth quarter of 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. 41 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Directors and Shareholders of PS Business Parks, Inc. We have audited PS Business Parks, Inc. internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). PS Business Parks, Inc. management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, PS Business Parks, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of PS Business Parks, Inc. as of December 31, 2012 and 2011, and the related consolidated statements of income, shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2012 and our report dated February 22, 2013 expressed an unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2012 1. Organization and description of business Organization PS Business Parks, Inc. (“PSB”) was incorporated in the state of California in 1990. As of December 31, 2012, PSB owned 76.9% of the common partnership units of PS Business Parks, L.P. (the “Operating Partnership”). The remaining common partnership units are owned by Public Storage (“PS”). PSB, as the sole general partner of the Operating Partnership, has full, exclusive and complete responsibility and discretion in managing and controlling the Operating Partnership. PSB and the Operating Partnership are collectively referred to as the “Company.” Description of business The Company is a fully-integrated, self-advised and self-managed real estate investment trust (“REIT”) that owns, operates, acquires and develops commercial properties, primarily multi-tenant flex, office and industrial space. As of December 31, 2012, the Company owned and operated 28.3 million rentable square feet of commercial space located in eight states. The Company also manages 1.2 million rentable square feet on behalf of PS. References to the number of properties or square footage are unaudited and outside the scope of the Company’s independent registered public accounting firm’s audit of the Company’s financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). 2. Summary of significant accounting policies Basis of presentation The accompanying consolidated financial statements include the accounts of PSB and the Operating Partnership. All significant inter-company balances and transactions have been eliminated in the consolidated financial statements. Noncontrolling Interests The Company’s noncontrolling interests are reported as a component of equity separate from the parent’s equity. Purchases or sales of equity interests that do not result in a change in control are accounted for as equity transactions. In addition, net income attributable to the noncontrolling interest is included in consolidated net income on the face of the income statement and, upon a gain or loss of control, the interest purchased or sold, as well as any interest retained, is recorded at fair value with any gain or loss recognized in earnings. Use of estimates The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles 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 53 accounts, which represents the cumulative allowances less write-offs of uncollectible rent, is netted against tenant and other receivables on the consolidated balance sheets. Tenant receivables are net of an allowance for uncollectible accounts totaling $400,000 at December 31, 2012 and 2011. 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 Level 3—fair value measurements derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable Financial assets that are exposed to credit risk consist primarily of cash and cash equivalents and receivables. The Company considers all highly liquid investments with a remaining maturity of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents, which consist primarily of money market investments, are only invested in entities with an investment grade rating. Receivables are comprised of balances due from a large number of customers. Balances that the Company expects to become uncollectible are reserved for or written off. Due to the short period to maturity of the Company’s cash and cash equivalents, accounts receivable, other assets and accrued and other liabilities, the carrying values as presented on the consolidated balance sheets are reasonable estimates of fair value. Carrying values of the Company’s mortgage notes payable, unsecured credit facility and term loan are deemed to approximate fair value. The characteristics of these financial instruments, market data and other comparative metrics utilized in determining these fair values are “Level 2” inputs. Real estate facilities Real estate facilities are recorded at cost. Costs related to the renovation or improvement of the properties are capitalized. Expenditures for repairs and maintenance are expensed as incurred. Expenditures that are expected to benefit a period greater than two years and exceed $2,000 are capitalized and depreciated over their estimated useful life. Buildings and improvements are depreciated using the straight-line method over their estimated useful lives, which generally range from five to 30 years. Transaction costs, which include tenant improvements and lease commissions, in excess of $1,000 for leases with terms greater than one year are capitalized and depreciated over their estimated useful lives. Transaction costs less than $1,000 or leases of one year or less are expensed as incurred. Properties held for disposition An asset is classified as an asset held for disposition when it meets certain requirements, which include, among other criteria, the approval of the sale of the asset, the marketing of the asset for sale and the expectation by the Company that the sale will likely occur within the next 12 months. Upon classification of an asset as held for disposition, depreciation of the asset is ceased, the operating results of the asset are included in discontinued operations for all periods presented and the net book value of the asset is included on the balance sheet as properties held for disposition. 54 Intangible assets/liabilities Intangible assets and liabilities include above-market and below-market in-place lease values of acquired properties based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease. The capitalized above-market and below-market lease values (included in other assets and accrued liabilities in the accompanying consolidated balance sheets) are amortized to rental income over the remaining non-cancelable terms of the respective leases. The Company recorded net amortization reducing rental income of $501,000, $843,000 and $571,000 of intangible assets and liabilities resulting from the above-market and below-market lease values during the years ended December 31, 2012, 2011 and 2010, respectively. As of December 31, 2012, the value of in-place leases resulted in a net intangible asset of $5.2 million, net of $4.7 million of accumulated amortization with a weighted average amortization period of 6.4 years, and a net intangible liability of $4.7 million, net of $3.0 million of accumulated amortization with a weighted average amortization period of 5.0 years. As of December 31, 2011, the value of in- place leases resulted in a net intangible asset of $6.9 million, net of $2.3 million of accumulated amortization and a net intangible liability of $6.4 million, net of $1.1 million of accumulated amortization. Evaluation of asset impairment The Company evaluates its assets used in operations for impairment by identifying indicators of impairment and by comparing the sum of the estimated undiscounted future cash flows for each asset to the asset’s carrying value. When indicators of impairment are present and the sum of the estimated undiscounted future cash flows is less than the carrying value of such asset, an impairment loss is recorded equal to the difference between the asset’s current carrying value and its value based on discounting its estimated future cash flows. In addition, the Company evaluates its assets held for disposition for impairment. Assets held for disposition are reported at the lower of their carrying value or fair value, less cost of disposition. At December 31, 2012, the Company did not consider any assets to be impaired. Asset impairment due to casualty loss It is the Company’s policy to record as a casualty loss or gain, in the period the casualty occurs, the differential between (a) the book value of assets destroyed and (b) any insurance proceeds that the Company expects to receive in accordance with its insurance contracts. Potential proceeds from insurance that are subject to any uncertainties, such as interpretation of deductible provisions of the governing agreements, the estimation of costs of restoration, or other such items, are treated as contingent proceeds and not recorded until the uncertainties are satisfied. For the years ended December 31, 2012, 2011 and 2010 no material casualty losses were incurred. Stock compensation All share-based payments to employees, including grants of employee stock options, are recognized as stock compensation in the Company’s income statement based on their grant date fair values. See Note 10. Revenue and expense recognition The Company must meet four basic criteria before revenue can be recognized: persuasive evidence of an arrangement exists; the delivery has occurred or services rendered; the fee is fixed or determinable; and collectability is reasonably assured. All leases are classified as operating leases. Rental income is recognized on a straight-line basis over the terms of the leases. Straight-line rent is recognized for all tenants with contractual fixed increases in rent that are not included on the Company’s credit watch list. Deferred rent receivable represents rental revenue recognized on a straight-line basis in excess of billed rents. Reimbursements from tenants for real estate taxes and other recoverable operating expenses are recognized as rental income in the period the applicable costs are incurred. Property management fees are recognized in the period earned. 55 Costs incurred in connection with leasing (primarily tenant improvements and lease commissions) are capitalized and amortized over the lease period. Gains from sales of real estate facilities The Company recognizes gains from sales of real estate facilities at the time of sale using the full accrual method, provided that various criteria related to the terms of the transactions and any subsequent involvement by the Company with the properties sold are met. If the criteria are not met, the Company defers the gains and recognizes them when the criteria are met or uses the installment or cost recovery methods as appropriate under the circumstances. General and administrative expenses General and administrative expenses include executive and other compensation, office expense, professional fees, acquisition transaction costs, state income taxes and other such administrative items. 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. 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 taxable income each year. In addition, REITs are subject to a number of organizational and operating requirements. If the Company fails to qualify as a REIT in any taxable year, the Company will be subject to federal income tax (including any applicable alternative minimum tax) based on its taxable income using corporate income tax rates. Even if the Company qualifies for taxation as a REIT, 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 2012, 2011 and 2010 and intends to continue to meet such requirements. 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 December 31, 2012, the Company did not recognize any tax benefit for uncertain tax positions. Accounting for preferred equity issuance costs The Company records issuance costs as a reduction to paid-in capital on its balance sheet at the time the preferred securities are issued and reflects the carrying value of the preferred equity at the stated value. The Company records issuance costs as non-cash preferred equity distributions at the time it notifies the holders of preferred stock or units of its intent to redeem such shares or units. 56 Net income allocation Net income was allocated as follows for the years ended December 31, (in thousands): 2012 2011 2010 Net income allocable to noncontrolling interests: Noncontrolling interests — common units: Continuing operations . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 5,744 $ 14,838 $ 10,307 1,287 Discontinued operations . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 226 705 Total net income allocable to noncontrolling interests — common units . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5,970 15,543 11,594 Noncontrolling interests — preferred units: Distributions to preferred unit holders . . . . . . . . . . . . . . . . . . . . . . . . .

The Company’s restricted stock units are participating securities and are included in the computation of basic and diluted weighted average common shares outstanding. The Company’s restricted stock unit holders are paid non-forfeitable dividends in excess of the expense recorded which results in a reduction in net income allocable to common shareholders and unit holders.

Acquisition related costs are expensed as incurred. In determining the fair value of the tangible assets of the acquired properties, management considers the value of the properties as if vacant as of the acquisition date. Management must make significant assumptions in determining the value of assets acquired and liabilities assumed. Using different assumptions in the recording of the purchase cost of the acquired properties would affect the timing of recognition of the related revenue and expenses. Amounts recorded to land are derived from comparable sales of land within the same region. Amounts recorded to buildings and improvements, tenant improvements and unamortized lease commissions are based on current market replacement costs and other market information. The amount recorded to acquired in-place leases is determined based on management’s assessment of current market conditions and the estimated lease-up periods for the respective spaces. In 2010, the Company completed construction on a parcel of land within the Miami International Commerce Center in Miami, Florida, which added 75,000 square feet of rentable small tenant industrial space. In October, 2012, the Company completed the sale of Quail Valley Business Park, a 66,000 square foot flex park in Houston, Texas, for a gross sales price of $2.3 million, resulting in a net gain of $935,000.

Bank loans The Company has a line of credit (the “Credit Facility”) with Wells Fargo Bank, National Association (“Wells Fargo”) which expires on August 1, 2015. The Credit Facility has a borrowing limit of $250.0 million. The rate of interest charged on borrowings is equal to a rate ranging from the London Interbank Offered Rate (“LIBOR”) plus 1.00% to LIBOR plus 1.85% depending on the Company’s credit ratings. Currently, the Company’s rate under the Credit Facility is LIBOR plus 1.10%. In addition, the Company is required to pay an annual facility fee ranging from 0.15% to 0.45% of the borrowing limit depending on the Company’s credit ratings (currently 0.15%). The Company had no balance outstanding on the Credit Facility at December 31, 2012. The Company had $185.0 million outstanding on the Credit Facility at an interest rate of 1.41% at December 31, 2011. The Company had $791,000 and $1.1 million of unamortized commitment fees as of December 31, 2012 and 2011, respectively. The Credit Facility requires the Company to meet certain covenants, with which the Company was in compliance at December 31, 2012 and 2011. Interest on outstanding borrowings is payable monthly.

Noncontrolling interests As described in Note 2, the Company reports noncontrolling interests within equity in the consolidated financial statements, but separate from the Company’s shareholders’ equity. In addition, net income allocable to noncontrolling interests is shown as a reduction from net income in calculating net income allocable to common shareholders. Common partnership units The Company presents the accounts of PSB and the Operating Partnership on a consolidated basis. Ownership interests in the Operating Partnership that can be redeemed for common stock, other than PSB’s interest, are classified as noncontrolling interests — common units in the consolidated financial statements. Net income allocable to noncontrolling interests — common units consists of the common units’ share of the consolidated operating results after allocation to preferred units and shares. Beginning one year from the date of admission as a limited partner (common units) and subject to certain limitations described below, each limited partner other than PSB has the right to require the redemption of its partnership interest. 63 A limited partner (common units) that exercises its redemption right will receive cash from the Operating Partnership in an amount equal to the market value (as defined in the Operating Partnership Agreement) of the partnership interests redeemed. In lieu of the Operating Partnership redeeming the common units for cash, PSB, as general partner, has the right to elect to acquire the partnership interest directly from a limited partner exercising its redemption right, in exchange for cash in the amount specified above or by issuance of one share of PSB common stock for each unit of limited partnership interest redeemed. A limited partner (common units) cannot exercise its redemption right if delivery of shares of PSB common stock would be prohibited under the applicable articles of incorporation, or if the general partner believes that there is a risk that delivery of shares of common stock would cause the general partner to no longer qualify as a REIT, would cause a violation of the applicable securities laws, or would result in the Operating Partnership no longer being treated as a partnership for federal income tax purposes. At December 31, 2012, there were 7,305,355 common units owned by PS, which are accounted for as noncontrolling interests. On a fully converted basis, assuming all 7,305,355 noncontrolling interests — common units were converted into shares of common stock of PSB at December 31, 2012, the noncontrolling interests — common units would convert into 23.1% of the shares of common stock then outstanding. Combined with PS’s existing common stock ownership, on a fully converted basis, PS has a combined ownership of 41.5% of the Company’s common equity. 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 interest based upon the ownership interest, and an adjustment is made to the noncontrolling interest, with a corresponding adjustment to paid-in capital, to reflect the noncontrolling interests’ equity interest in the Company. Preferred partnership units Through the Operating Partnership, the Company had the following preferred units outstanding as of December 31, 2012 and 2011: Series Issuance Date Earliest Potential Redemption Date Dividend Rate Units Outstanding Amount (in thousands) Units Outstanding Amount (in thousands) Series N . . . . .

The Company reported the excess of the redemption amount over the carrying amount of $149,000, equal to the original issuance costs, as a reduction of net income allocable to common shareholders and unit holders for the year ended December 31, 2012. In February, 2011, the Company paid an aggregate of $39.1 million to repurchase 1,710,000 units of its 7.50% Series J Cumulative Redeemable Preferred Units and 203,400 units of its 6.55% Series Q Cumulative Redeemable Preferred Units for a weighted average purchase price of $20.43 per unit. The aggregate par value of the repurchased preferred units was $47.8 million, which generated a gain of $7.4 million, net of original issuance costs of $1.4 million, which was added to net income allocable to common shareholders and unit holders for the year ended December 31, 2011. On May 12, 2010, the Company redeemed 800,000 units of its 7.950% Series G Cumulative Redeemable Preferred Units for $20.0 million.

Stock compensation PSB has a 2003 Stock Option and Incentive Plan (the “2003 Plan”) covering 1.5 million shares of PSB’s common stock. Under the 2003 Plan, PSB has granted non-qualified options to certain directors, officers and key employees to purchase shares of PSB’s common stock at a price not less than the fair market value of the common stock at the date of grant. Additionally, under the 2003 Plan, PSB has granted restricted stock units to officers and key employees. Effective February 20, 2012, PSB has a 2012 Equity and Performance-Based Incentive Compensation Plan (the “2012 Plan”) covering 1.0 million shares of PSB’s common stock. Under the 2012 Plan, PSB has granted non-qualified options to certain directors 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 2012 Plan, PSB has granted restricted shares of common stock to certain directors. Options under the 2003 Plan and 2012 Plan vest over a five-year period from the date of grant at the rate of one fifth per year and expire 10 years after the date of grant. Generally, restricted stock units granted are subject to a six-year vesting schedule, none in year one and 20% for each of the next five years. Certain restricted stock unit grants are subject to a three-year vesting schedule with 33.3% vesting for each of the three years. 67 The weighted average grant date fair value of options granted in the years ended December 31, 2012, 2011 and 2010 were $4.85 per share, $5.38 per share and $6.08 per share, respectively. The Company has calculated the fair value of each option grant on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions used for grants for the years ended December 31, 2012, 2011 and 2010, respectively; a dividend yield of 2.6%, 2.9% and 3.3%; expected volatility of 13.4%, 13.9% and 17.5%; expected life of five years; and risk-free interest rates of 0.9%, 1.7% and 2.4%. The estimated grant-date fair value of restricted stock units is recognized as compensation expense over the applicable vesting period, net of estimates for future forfeitures. Fair value is determined based upon the closing trading price of our common shares on the grant date. The employer portion of payroll taxes is expensed as incurred. The straight-line attribution method is used with respect to option and restricted stock unit grants that are earned solely based upon the passage of time and continued employment. Performance — based restricted stock unit grants are amortized using the accelerated attribution method, with each vesting amortized separately over the individual vesting period. The weighted average grant date fair value of restricted stock units granted during the years ended December 31, 2012, 2011 and 2010 were $65.14, $51.63 and $54.44, respectively. The Company calculated the fair value of each restricted stock unit grant using the market value on the date of grant. At December 31, 2012, there were a combined total of 975,000 options and restricted stock units authorized to grant.
