EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended September 30, 2011 of Kilroy Realty Corporation and Kilroy Realty, L.P. Unless stated otherwise or the context otherwise requires, references to "Kilroy Realty Corporation" or the "Company," "we," "our," and "us" mean Kilroy Realty Corporation, a Maryland corporation, and its controlled and consolidated subsidiaries, and references to "Kilroy Realty, L.P." or the "Operating Partnership" mean Kilroy Realty, L.P., a Delaware limited partnership, and its controlled and consolidated subsidiaries.

The Company is a real estate investment trust, or REIT, and the general partner of the Operating Partnership. As of September 30, 2011 , the Company owned an approximate 97.1% common general partnership interest in the Operating Partnership. The remaining approximate 2.9% common limited partnership interests are owned by non-affiliated investors and certain directors and officers of the Company. As the sole general partner of the Operating Partnership, the Company exercises exclusive and complete discretion over the Operating Partnership's day-to-day management and control and can cause it to enter into certain major transactions including acquisitions, dispositions, and refinancings and cause changes in its line of business, capital structure, and distribution policies.

There are a few differences between the Company and the Operating Partnership which are reflected in the disclosures in this Form 10-Q. We believe it is important to understand the differences between the Company and the Operating Partnership in the context of how the Company and the Operating Partnership operate as an interrelated, consolidated company. The Company is a REIT, the only material asset of which is the partnership interests it holds in the Operating Partnership. As a result, the Company does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing equity from time to time and guaranteeing certain debt of the Operating Partnership. The Company itself is not directly obligated under any indebtedness, but guarantees some of the debt of the Operating Partnership. The Operating Partnership owns substantially all of the assets of the Company either directly or through its subsidiaries, conducts the operations of the Company's business and is structured as a limited partnership with no publicly traded equity. Except for net proceeds from equity issuances by the Company, which the Company is required to contribute to the Operating Partnership in exchange for partnership units, the Operating Partnership generates the capital required by the Company's business through the Operating Partnership's operations, by the Operating Partnership's incurrence of indebtedness or through the issuance of partnership units.

Noncontrolling interests and stockholders' equity and partners' capital are the main areas of difference between the consolidated financial statements of the Company and those of the Operating Partnership. The common limited partnership interests in the Operating Partnership are accounted for as partners' capital in the Operating Partnership's financial statements and as noncontrolling interests in the Company's financial statements. The Operating Partnership's financial statements reflect the noncontrolling interest in Kilroy Realty Finance Partnership, L.P. This noncontrolling interest represents the Company's 1% indirect general partnership interest in Kilroy Realty Finance Partnership, L.P., which is directly held by Kilroy Realty Finance, Inc., a wholly-owned subsidiary of the Company. The differences between stockholders' equity, partners' capital and noncontrolling interests result from the differences in the equity issued by the Company and the Operating Partnership, and in the Company's noncontrolling interest in Kilroy Realty Finance Partnership, L.P.

We believe combining the quarterly reports on Form 10-Q of the Company and the Operating Partnership into this single report results in the following benefits:


•	Combined reports better reflect how management and the analyst community view the business as a single operating unit;


•	Combined reports enhance investors' understanding of the Company and the Operating Partnership by enabling them to view the business as a whole and in the same manner as management;


•	Combined reports are more efficient for the Company and the Operating Partnership and result in savings in time, effort and expense; and


•	Combined reports are more efficient for investors by reducing duplicative disclosure and providing a single document for their review.

To help investors understand the significant differences between the Company and the Operating Partnership, this report presents the following separate sections for each of the Company and the Operating Partnership:


•	consolidated financial statements;


•	the following notes to the consolidated financial statements:


◦	Note 5, Secured and Unsecured Debt of the Operating Partnership;


◦	Note 6, Noncontrolling Interests on the Company's Consolidated Financial Statements;


◦	Note 7, Stockholders' Equity of the Company;


◦	Note 8, Partners' Capital of the Operating Partnership;


◦	Note 15, Net Income (Loss) Available to Common Stockholders Per Share of the Company;


◦	Note 16, Net Income (Loss) Available to Common Unitholders Per Unit of the Operating Partnership;


◦	Note 18, Pro Forma Results of the Company;


◦	Note 19, Pro Forma Results of the Operating Partnership;


•	"Item 2: Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources of the Company";


•	"Item 2: Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources of the Operating Partnership".

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

1. Organization and Basis of Presentation

Organization

Kilroy Realty Corporation (the "Company") is a self-administered real estate investment trust (“REIT”) active in office and industrial submarkets along the West Coast. We own, develop, acquire and manage real estate assets, consisting primarily of Class A properties in the coastal regions of Los Angeles, Orange County, San Diego, greater Seattle and the San Francisco Bay Area, which we believe have strategic advantages and strong barriers to entry. We qualify as a REIT under the Internal Revenue Code of 1986, as amended (the "Code"). The Company's common stock is publicly traded on the New York Stock Exchange (“NYSE”) under the ticker symbol “KRC.”

We own our interests in all of our real estate assets through Kilroy Realty, L.P. (the "Operating Partnership") and Kilroy Realty Finance Partnership, L.P. (the "Finance Partnership"). We conduct substantially all of our operations through the Operating Partnership. Unless stated otherwise or the context indicates otherwise, the terms "Kilroy Realty Corporation" or the "Company," "we," "our," and "us" refer to Kilroy Realty Corporation and its consolidated subsidiaries and the term "Operating Partnership" refers to Kilroy Realty, L.P. and its consolidated subsidiaries. The descriptions of our business, employees, and properties apply to both the Company and the Operating Partnership.

The following table of office buildings (the "Office Properties") and industrial buildings (the "Industrial Properties") summarizes our stabilized portfolio of operating properties as of September 30, 2011 . As of September 30, 2011 , all of our properties and all of our business is currently conducted in the state of California with the exception of the operation of six office properties located in the state of Washington.

________________________

(1) Includes nine office properties acquired during the nine months ended September 30, 2011 for a total amount of $516.3 million (see Note 2 for additional information).

Our stabilized portfolio excludes undeveloped land, development and redevelopment properties currently under construction or committed for construction, "lease-up" properties, and one property we are currently in the process of repositioning for residential use. As of September 30, 2011 , we had three office redevelopment properties under construction encompassing approximately 508,000 rentable square feet. We commenced redevelopment on two of the three redevelopment properties in the third quarter of 2011. We define "lease-up" properties as properties we recently developed or redeveloped that have not yet reached 95% occupancy and are within one year following cessation of major construction activities. We had no "lease-up" properties as of September 30, 2011 . In addition, as of September 30, 2011 we had one industrial property that we were in the process of demolishing to prepare the land for potential sale. We successfully obtained entitlements to reposition this site for residential use in 2011. Ultimate timing of the potential sale will depend upon market conditions and other factors.

As of September 30, 2011 , the Company owned a 97.1% general partnership interest in the Operating Partnership. The remaining 2.9% common limited partnership interest in the Operating Partnership as of September 30, 2011 was owned by non-affiliated investors and certain of our directors and officers (see Note 6). Both the general and limited common partnership interests in the Operating Partnership are denominated in common units. The number of common units held by the Company is at all times equivalent to the number of outstanding shares of the Company's common stock, and the rights of all the common units to quarterly distributions and payments in liquidation mirror those of the Company's common stockholders. The common limited partners have certain redemption rights as provided in the Operating Partnership's Fifth Amended and Restated Agreement of Limited Partnership (as amended, the “Partnership Agreement”) (see Note 6).

Kilroy Realty Finance, Inc., our wholly-owned subsidiary, is the sole general partner of the Finance Partnership and owns a 1.0% general partnership interest. The Operating Partnership owns the remaining 99.0% limited partnership interest. Kilroy Services, LLC ("KSLLC"), which is a wholly-owned subsidiary of the Operating Partnership, is the entity through which we conduct substantially all of our development activities. With the exception of the Operating Partnership, all of our subsidiaries, which include Kilroy Realty TRS, Inc., Kilroy Realty Management, L.P., Kilroy RB, LLC, Kilroy RB II, LLC, Kilroy Realty

Basis of Presentation

The consolidated financial statements of the Company include the consolidated financial position and results of operations of the Company, the Operating Partnership, the Finance Partnership, KSLLC, and all of our wholly-owned subsidiaries. The consolidated financial statements of the Operating Partnership include the consolidated financial position and results of operations of the Operating Partnership, the Finance Partnership, KSLLC, and all wholly-owned subsidiaries of the Operating Partnership. All intercompany balances and transactions have been eliminated in the consolidated financial statements.

The consolidated financial statements of the Company and the Operating Partnership also include two variable interest entities ("VIE") in which we are deemed to be the primary beneficiary. We had one bankruptcy-remote VIE, which was formed in 2010 to hold three properties that secure the debt we assumed when we acquired the properties in 2010 . The assets held by this entity are not available to satisfy the debts and other obligations of the Company or the Operating Partnership. In September 2011, we acquired a building which was transferred to a special purpose VIE to facilitate a potential tax-deferred property exchange pursuant to Section 1031 of the Code for federal and state income tax purposes ("Section 1031 Exchange"). The Company is obligated to complete the Section 1031 Exchange and take title to the property within 180 days of the initial acquisition date. The VIE will be terminated upon the completion of the Section 1031 Exchange. The impact of consolidating both VIEs increased the Company's total assets and liabilities by approximately $164.0 million and $63.0 million , respectively, at September 30, 2011 .

The accompanying interim financial statements have been prepared by management in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in conjunction with the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, the interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the accompanying interim financial statements reflect all adjustments of a normal and recurring nature that are considered necessary for a fair presentation of the results for the interim periods presented. However, the results of operations for the interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2011. The interim financial statements for the Company and the Operating Partnership should be read in conjunction with the audited consolidated financial statements and notes thereto included in our annual report on Form 10-K for the year ended December 31, 2010 .

Change in Reportable Segments from Form 10-K for the year ended December 31, 2010

Our chief operating decision-makers internally evaluate the operating performance and financial results of our portfolio based on Net Operating Income for the following two segments of commercial real estate property: Office Properties and Industrial Properties. We define “Net Operating Income” as operating revenues (rental income, tenant reimbursements, and other property income) less operating expenses (property expenses, real estate taxes, provision for bad debts, and ground leases).

During the three and nine months ended September 30, 2011 , the amount of revenues and Net Operating Income generated by our Industrial Properties, in relation to our total consolidated operating portfolio revenues and Net Operating Income fell below the required 10% quantitative reporting thresholds for the Industrial Properties to be considered a reportable segment under GAAP. Therefore, for the three and nine months ended September 30, 2011 , our only reportable segment is our Office Properties segment. See Note 13 for a reconciliation of our Office Properties segment to our consolidated revenues, Net Operating Income, net income and consolidated assets.

5. Secured and Unsecured Debt of the Operating Partnership

Secured Debt

In January 2011, the Operating Partnership borrowed $135.0 million under a mortgage loan that is scheduled to mature on February 1, 2018 . The mortgage loan is secured by our 303 Second Street property in San Francisco, bears interest at an annual rate of 4.27% , and requires interest-only payments for the first two years with a 30 -year amortization schedule thereafter. We used a portion of the proceeds to repay borrowings under the Operating Partnership's unsecured line of credit (the "Credit Facility").

In April 2011, in connection with the acquisition of four office buildings in Kirkland, Washington, the Operating Partnership assumed a mortgage loan that is secured by the project. The assumed mortgage loan had a principal balance of $30.0 million at the acquisition date and is scheduled to mature on April 15, 2015 . The loan bears contractual interest at an annual rate of 4.94% and requires monthly principal and interest payments based on a 30 -year amortization period. This mortgage loan was recorded at fair value at the date of acquisition resulting in a premium of approximately $1.0 million . This premium will be accreted on a straight-line basis, which approximates the effective interest method, as a reduction to interest expense from the acquisition date through the maturity date of the mortgage loan. This will result in interest being recorded at an effective interest rate of 4.00% for financial reporting purposes.

Although both new mortgage loans are secured and non-recourse to the Company and the Operating Partnership, the Company provides limited customary secured debt guarantees for items such as voluntary bankruptcy, fraud, misapplication of payments, and environmental liabilities.

(4)	The exchange rate, exchange price, and the number of shares to be delivered upon conversion are subject to adjustment under certain circumstances including increases in our

common dividends.

Capped Call Transactions

In connection with the offerings of the Exchangeable Notes, we entered into capped call option transactions ("capped calls") to mitigate the dilutive impact of the potential exchange of the Exchangeable Notes. The following table summarizes our capped call option positions as of both September 30, 2011 and December 31, 2010 :



	3.25% Exchangeable Notes ⁽¹⁾		4.25% Exchangeable Notes ⁽²⁾
Referenced shares of common stock	1,121,201		4,800,796
Exchange price including effect of capped calls	$	102.72	$	42.81

________________________


(1)	The capped calls mitigate the dilutive impact to us of the potential exchange of two-thirds of the 3.25% Exchangeable Notes into shares of common stock.


(2)	The capped calls mitigate the dilutive impact to us of the potential exchange of all of the 4.25% Exchangeable Notes into shares of common stock.

For the nine months ended September 30, 2011 , the per share average trading price of the Company's common stock on the NYSE of $37.92 was higher than the $35.93 exchange price for the 4.25% Exchangeable Notes. Even though the 4.25% Exchangeable Notes were not convertible as of September 30, 2011 , if they were convertible as of September 30, 2011 , the approximate fair value of the shares upon conversion at that date would have been equal to approximately $180.4 million , which would exceed the $172.5 million principal amount of the 4.25% Exchangeable Notes by approximately $7.9 million . See Notes 15 and 16 for a discussion of the impact of the Exchangeable Notes on our diluted earnings per share and unit calculations for the periods presented.

Unsecured Senior Notes

In July 2011, the Operating Partnership issued unsecured senior notes in a public offering with an aggregate principal balance of $325.0 million that are scheduled to mature on July 15, 2018 . The unsecured senior notes require semi-annual interest payments each January and July based on a stated annual interest rate of 4.80% . The unsecured senior notes are shown net of the initial issuance discount of $0.5 million on the consolidated balance sheets. This discount is being amortized on a straight-line basis, which approximates the effective interest method, as additional interest expense from the date of issuance through the maturity date of the unsecured senior notes, resulting in interest expense being recorded at a net effective interest rate of 4.83% , before the impact of debt issuance costs, for financial reporting purposes. The Company used a portion of the net proceeds for general corporate purposes, including the repayment of borrowings under the Operating Partnership's Credit Facility.

Unsecured Line of Credit

In June 2011, we amended the terms of our Credit Facility to extend the maturity date, and reduce the interest rate and facility fee. The following table summarizes the terms of our Credit Facility as of December 31, 2010 and as amended as of September 30, 2011 :

(1) As of September 30, 2011 , there were no borrowings outstanding on the Credit Facility.

(2) We may elect to borrow, subject to lender approval, up to an additional $200 million under an accordion feature under the terms of the Credit Facility.

(3) The Credit Facility interest rate was calculated based on an annual rate of LIBOR plus 1.750% and 2.675% as of September 30, 2011 and December 31, 2010 , respectively. No interest rate is shown as of September 30, 2011 because no borrowings were outstanding.

(4) The facility fee is paid on a quarterly basis and is calculated based on the total borrowing capacity. In addition to the facility fee, we also incurred debt origination and legal costs

of approximately $5.0 million when we entered into the Credit Facility in 2010 and an additional $3.3 million when we amended the Credit Facility in 2011. The unamortized

balance of these costs will be amortized as additional interest expense over the extended term of the Credit Facility.

Debt Covenants and Restrictions

The Credit Facility, the unsecured senior notes, and certain other secured debt arrangements contain covenants and restrictions requiring us to meet certain financial ratios and reporting requirements. Some of the more restrictive financial covenants include a maximum ratio of total debt to total asset value, a minimum fixed-charge coverage ratio, a minimum unsecured debt ratio, and a minimum unencumbered asset pool debt service coverage ratio. Noncompliance with one or more of the covenants and restrictions could result in the full or partial principal balance of the associated debt becoming immediately due and payable. We believe we were in compliance with all of our debt covenants as of September 30, 2011 .

6. Noncontrolling Interests on the Company's Consolidated Financial Statements

7.45% Series A Cumulative Redeemable Preferred Units of the Operating Partnership

As of both September 30, 2011 and December 31, 2010 , the Operating Partnership had outstanding 1,500,000 7.45% Series A Cumulative Redeemable Preferred Units representing preferred limited partnership interests in the Operating Partnership with a redemption value of $50.00 per unit. There were no changes to this noncontrolling interest during the three and nine months ended September 30, 2011 and 2010 .

Common Units of the Operating Partnership

The Company owned a 97.1% , 96.8% and 96.8% common general partnership interest in the Operating Partnership as of September 30, 2011 , December 31, 2010 , and September 30, 2010 , respectively. The remaining 2.9% , 3.2% and 3.2% common limited partnership interest as of September 30, 2011 , December 31, 2010 and September 30, 2010 , respectively, was owned in the form of common units by non-affiliate investors and certain of our officers and directors. There were 1,718,131 , 1,723,131 and 1,723,131 common units outstanding held by these investors, officers and directors as of September 30, 2011 , December 31, 2010 and September 30, 2010 , respectively.

The noncontrolling common units may be redeemed by unitholders for cash. We, at our option, may satisfy the cash redemption obligation with shares of the Company's common stock on a one-for-one basis . Whether satisfied in cash or shares of the Company's

common stock, the value for each noncontrolling common unit upon redemption is the amount equal to the average of the closing quoted price per share of the Company's common stock, par value $.01 per share, as reported on the NYSE for the ten trading days immediately preceding the applicable redemption date. The aggregate value upon redemption of the then-outstanding noncontrolling common units was $56.2 million and $61.4 million as of September 30, 2011 and December 31, 2010 , respectively. This redemption value does not necessarily represent the amount that would be distributed with respect to each common unit in the event of our termination or liquidation. In the event of our termination or liquidation, it is expected in most cases that each common unit would be entitled to a liquidating distribution equal to the amount payable with respect to each share of the Company's common stock.

10. Future Minimum Rent

We have operating leases with tenants that expire at various dates through 2031 and are either subject to scheduled fixed increases or adjustments in rent based on the Consumer Price Index. Generally, the leases grant tenants renewal options. Leases also provide for additional rents based on certain operating expenses. Future contractual minimum rent under operating leases as of September 30, 2011 for future periods is summarized as follows:

Ground Leases

We have noncancellable ground lease obligations at one building in Bellevue, Washington which expires in November 2093 and at Kilroy Airport Center Phases I, II, and III in Long Beach, California which expires in July 2084.

The minimum commitment under our ground leases as of September 30, 2011 for five years and thereafter was as follows:

(2)

One of our ground lease obligations includes a component which is based on the percentage of gross income that exceeds the minimum ground rent. The minimum rent is subject to increases every five years based on 50% of the average annual percentage rent for the previous five years. Currently gross income does not exceed the threshold requiring us to pay percentage rent. The contractual obligations for that ground lease included above assumes the annual lease rental obligation in effect as of September 30, 2011 .

Non-refundable Escrow Deposits

As of September 30, 2011 , we had $11.0 million in non-refundable escrow deposits, subject only to the failure of satisfaction of conditions precedent to the closing. The escrow deposits are related to potential future acquisitions, which are included in prepaid expenses and other assets, net on the consolidated balance sheets. These potential future acquisitions are currently anticipated to close in 2011 and are subject to customary closing conditions.

13. Segment Disclosure

We have one reportable segment which is our Office Properties segment and we have one non-reportable segment which is our Industrial Properties segment. We also have certain corporate level activities including legal administration, accounting, finance, management information systems, and acquisitions, which are not considered separate operating segments.

We evaluate the performance of our segments based upon Net Operating Income. “Net Operating Income” is defined as operating revenues (rental income, tenant reimbursements, and other property income) less property and related expenses (property expenses, real estate taxes, ground leases, and provisions for bad debts) and excludes other non-property related income and expenses such as interest income and interest expense, depreciation and amortization, acquisition-related expenses and corporate general and administrative expenses. There is no intersegment activity.

The following tables reconcile our reportable segment activity to our consolidated net income for the three and nine months ended September 30, 2011 and 2010 and the assets by segment to the consolidated assets as of September 30, 2011 and December 31, 2010 :

The impact of the Exchangeable Notes and stock options was not considered in our diluted earnings per share calculation for the three and nine months ended September 30, 2011 and the three months ended September 30, 2010 since the Company had losses from continuing operations attributable to common stockholders in the respective periods and the effect was anti-dilutive.

The impact of the Exchangeable Notes was not included in our diluted earnings per share calculation for the nine months ended September 30, 2010 because the average trading price of the Company's common stock on the NYSE was below the respective Exchangeable Notes exchange price for the period. As a result, these instruments were not considered to be dilutive for the purposes of our diluted earnings per share calculation for this period.

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

OPERATIONS

The following discussion relates to our consolidated financial statements and should be read in conjunction with the financial statements and notes thereto appearing elsewhere in this report. The results of operations discussion is combined for the Company and the Operating Partnership because there are no material differences in the results of operations between the two reporting entities.

Statements contained in this "Management's Discussion and Analysis of Financial Condition and Results of Operations" that are not historical facts may be forward-looking statements. Such statements are subject to certain risks and uncertainties, which could cause actual results to differ materially from those projected. Some of the information presented is forward-looking in nature, including information concerning projected future occupancy rates, rental rate increases, property development and redevelopment timing and costs, and investment amounts. Numerous factors could affect our actual results, some of which are beyond our control. These include the breadth and duration of the current slowness of economic growth and its impact on our tenants, the strength of commercial and industrial real estate markets, market conditions affecting tenants, our ability to complete and successfully integrate pending and recent acquisitions, the ability to successfully execute our capital recycling program including any potential dispositions and tax-deferred property exchanges, competitive market conditions, interest rate levels, volatility in the trading prices of the Company's securities, and capital market conditions. You are cautioned not to place undue reliance on this information, which speaks only as of the date of this report. We assume no obligation to update publicly any forward-looking information, whether as a result of new information, future events, or otherwise, except to the extent we are required to do so in connection with our ongoing requirements under federal securities laws to disclose material information. For a discussion of important risks related to our business, and related to investing in our securities, including risks that could cause actual results and events to differ materially from results and events referred to in the forward-looking information, see “Item 1A: Risk Factors" in the Company's and the Operating Partnership's annual report on Form 10-K for the year ended December 31, 2010, and the discussion below under the captions "—Factors That May Influence Future Results of Operations,” “—Liquidity and Capital Resources of the Company” and "—Liquidity and Capital Resources of the Operating Partnership." In light of these risks, uncertainties, and assumptions, the forward-looking events discussed in this report might not occur.

Overview and Background

We are a self-administered REIT active in office and industrial submarkets along the West Coast. We own, develop, acquire and manage real estate assets, consisting primarily of Class A real estate properties in the coastal regions of Los Angeles, Orange County, San Diego, greater Seattle and the San Francisco Bay Area, which we believe have strategic advantages and strong barriers to entry. We own our interests in all of our properties through the Operating Partnership and the Finance Partnership, and conduct substantially all of our operations through the Operating Partnership. We owned a 97.1% , 96.8% and 96.8% general partnership interest in the Operating Partnership as of September 30, 2011 , December 31, 2010 and September 30, 2010 , respectively. All our properties are held in fee except for the seven office buildings located at Kilroy Airport Center in Long Beach, California which are held subject to noncancellable ground leases for the land that expire in 2084 and one office building located in Bellevue, Washington which is held subject to a noncancellable ground lease for the land that expires in 2093.

Factors That May Influence Future Results of Operations

Acquisitions . During the nine months ended September 30, 2011 , we acquired nine office buildings in six transactions for approximately $516.3 million (see Note 2 to our consolidated financial statements included in this report for more information), and during 2010 we acquired ten office buildings in eight transactions for approximately $697.8 million . We generally finance our acquisitions through the assumption of existing debt, new debt and equity offerings, borrowings under our unsecured line of credit (the "Credit Facility") and proceeds from our capital recycling program.

As a key component of our growth strategy, we continually evaluate property acquisition opportunities as they arise. As a result, at any point in time we may have one or more potential acquisitions under consideration that are in varying stages of evaluation, negotiation or due diligence review, including potential acquisitions under contract. Although, as of the date of this report we are a party to agreements to acquire properties, and in the future may enter into additional agreements to acquire properties, those agreements are and will be subject to the satisfaction of due diligence review and customary closing conditions. We cannot provide assurance that we will enter into any additional agreements to acquire properties or that the acquisitions contemplated by the agreements to which we were a party as of the date of this report or any additional agreements we may enter into in the future will be completed. Costs associated with acquisitions are expensed as incurred and we may be unable to complete an acquisition after making a nonrefundable deposit or incurring acquisition-related costs. In addition, acquisitions are subject to various other risks and uncertainties. During the three and nine months ended September 30, 2011 , we incurred approximately $1.2 million and $2.8 million , respectively, of third-party acquisition costs and we anticipate that we will incur additional third-

party acquisition costs in the fourth quarter of 2011 as we pursue other potential acquisitions.

Capital Recycling Program. As part of our current strategy, we intend to dispose of mature office and industrial assets and then use the proceeds to fund potential acquisitions, to finance development and redevelopment expenditures, to potentially repay long-term debt and general corporate purposes. As part of this strategy, we intend, when practical, to enter into Section 1031 Exchanges to shelter the gains on the sales for federal and state income tax purposes.

In connection with this strategy, during the nine months ended September 30, 2011, we disposed of two office buildings in one transaction for approximately $23.9 million (see Note 14 to our consolidated financial statements included in this report for more information). At September 30, 2011, the net cash proceeds from this disposition were temporarily being held by a qualified intermediary, at our direction, for the purpose of facilitating a potential Section 1031 Exchange. In addition, during the third quarter of 2011 we began demolition of one of our industrial properties to prepare the land for the potential sale to residential developers since we successfully obtained entitlements to reposition this site for residential use. We anticipate that we could potentially sell this land in the next year, however ultimate timing of the sale will depend upon market conditions and other factors.

As part of our capital recycling program strategy, we are in various stages of negotiation for the disposition of four properties, including the land sale referenced above, with an aggregate sales price of approximately $205 million . In addition, we believe that we could potentially dispose of additional properties over the next 12 to 18 months, depending on market conditions. However, we cannot provide assurance that we will consummate any of these possible dispositions or, if we do, that the amount of proceeds from those dispositions will not be less, perhaps substantially, than the foregoing amounts.

Leasing Activity and Changes in Rental Rates . The amount of net rental income generated by our properties depends principally on our ability to maintain the occupancy rates of currently leased space and to lease currently available space, newly developed or redeveloped properties, newly acquired properties with vacant space, and space available from unscheduled lease terminations. The amount of rental income we generate also depends on our ability to maintain or increase rental rates in our submarkets. Negative trends in one or more of these factors could adversely affect our rental income in future periods. The following tables set forth certain information regarding leases that commenced during the three and nine months ended September 30, 2011.

______________


(1)	First generation leasing includes space where we have made capital expenditures that result in additional revenue generated when the space is re-leased. Second generation leasing includes space where we have made capital expenditures to maintain the current market revenue stream.


(2)	Represents leasing activity for leases that commenced during the period, including first and second generation space, net of month-to-month leases. Excludes development and redevelopment leasing.


(3)	Calculated as the change between GAAP rents for new/renewed leases and the expiring GAAP rents for the same space. Excludes leases for which the space was vacant longer than one year, or vacant when the property was acquired.


(4)	Calculated as the change between stated rents for new/renewed leases and the expiring stated rents for the same space. Excludes leases for which the space was vacant longer than one year, or vacant when the property was acquired.


(5)	Calculated as the percentage of space either renewed or expanded into by existing tenants or subtenants at lease expiration.

The changes in rents and changes in cash rents reported above exclude leases of approximately 224,500 and 684,600 rentable square feet for the three and nine months ended September 30, 2011 , respectively, for which the space was vacant longer than one year or we are leasing the space for the first time. We exclude space vacant for more than one year in our change in rents calculations to provide a meaningful market comparison.

During the three months ended September 30, 2011, we executed 30 leases for an aggregate of approximately 530,300 rentable square feet. The weighted average change in rents as compared to the expiring rents for the same space for these new leases was a 1.8% decrease in GAAP rents and a 8.0% decrease in cash rents, excluding leases for which the space was vacant longer than one year, or spaces we leased for the first time. As of September 30, 2011 , we believe that the weighted average cash rental rates for our overall portfolio, including recently acquired properties, are approximately 5% to 10% above the current average market rental rates, although individual properties within any particular submarket presently may be leased either above, below, or at the current market rates within that submarket, and the average rental rates for individual submarkets may be above, below, or at the average cash rental rate of our portfolio.

In general, rental rates have stabilized in many of our submarkets over the last several quarters. Our rental rates and occupancy are impacted by general economic conditions, including the pace of regional economic growth and access to capital. Therefore, we cannot give any assurance that leases will be renewed or that available space will be re-leased at rental rates equal to or above the current market rates. Additionally, decreased demand and other negative trends or unforeseeable events that impair our ability to timely renew or re-lease space could have further negative effects on our future financial condition, results of operations, and cash flows.

Scheduled Lease Expirations . The following table sets forth certain information regarding our lease expirations for the remainder of 2011 and the next five years.

________________________


(1)	The information presented reflects leasing activity through September 30, 2011 . For leases that have been renewed early or space that has been re-leased to a new tenant, the expiration date and annualized base rent information presented takes into consideration the renewed or re-leased lease terms. Excludes space leased under month-to-month leases and vacant space as of September 30, 2011 .

(2)

Reflects annualized contractual base rent calculated on a straight-line basis in accordance with GAAP excluding the amortization of deferred revenue related to tenant-funded tenant improvements and expense reimbursement revenue. Additionally, the underlying leases contain various expense structures including full service gross, modified gross and triple net. Amounts represent percentage of total portfolio annualized contractual base rental revenue.

In addition to the 1.1 million rentable square feet, or 7.2% , of currently available space in our stabilized portfolio, leases representing approximately 0.5% and 8.2% of the occupied square footage of our stabilized portfolio are scheduled to expire during the remainder of 2011 and in 2012, respectively. The leases scheduled to expire during the remainder of 2011 and in 2012

represent approximately 0.9 million rentable square feet of office space, or 6.9% of our total annualized base rental revenue, and 0.4 million rentable square feet of industrial space, or 0.7% of our total annualized base rental revenue, respectively. We believe that the weighted average cash rental rates are approximately 10% to 15% above the current average quoted market rates for leases scheduled to expire during the remainder of 2011 and 2012, although individual properties within any particular submarket presently may be leased either above, below, or at the current quoted market rates within that submarket, and the average rental rates for individual submarkets may be above, below, or at the average cash rental rate of our overall portfolio. Our ability to re-lease available space depends upon both general market conditions and the market conditions in the specific regions in which individual properties are located.

Development and Redevelopment Programs . We believe that a portion of our long-term future potential growth will continue to come from our development pipeline and redevelopment opportunities within our existing portfolio. Redevelopment opportunities are those projects in which we spend significant development and construction costs on existing buildings pursuant to a formal plan, the intended result of which is a higher economic return on the property.

During the three months ended September 30, 2011, we commenced the redevelopment of two of our existing office properties to upgrade and modernize the buildings and adjacent common areas. One office property is located in the Long Beach submarket of Los Angeles and encompasses approximately 98,000 rentable square feet. The redevelopment will occur in two phases and the existing tenant will occupy approximately 50% of the property during redevelopment. The redevelopment project has a total estimated investment of approximately $19.3 million at completion, including the $6.3 million net carrying value of the project at the commencement of redevelopment. Construction is currently expected to be completed in the second quarter of 2012.

The second office redevelopment property is located in the Sorrento Mesa submarket of San Diego and encompasses approximately 111,000 rentable square feet. The property is 100% pre-leased to a single tenant. As part of the redevelopment, we will be incorporating one of our undeveloped land parcels. The redevelopment project has a total estimated investment of approximately $38.8 million at completion, including the $22.2 million net carrying value of the project at the commencement of redevelopment. Construction is currently expected to be completed in the third quarter of 2012.

During the three months ended September 30, 2010 we commenced the redevelopment of one of our buildings in the El Segundo submarket of Los Angeles County which encompasses approximately 299,000 rentable square feet. We are currently upgrading and modernizing the building and adjacent common areas since it was previously occupied by the Boeing Company and its predecessors for more than 25 years. The redevelopment project has a total estimated investment of approximately $58.3 million at completion, including the $9.1 million net carrying value of the project at the commencement of redevelopment. Construction is currently expected to be completed in the third quarter of 2012. The building is 100% pre-leased to DIRECTV, Inc. Upon commencement of the lease for the 299,000 rentable square feet at this building, we project that DIRECTV, Inc. will become our largest tenant based on annualized base rental revenue. Upon completion of the redevelopment, DIRECTV, Inc. will lease approximately 630,000 rentable square feet and represent approximately 6% of our projected annualized base rental revenue.

In recent periods we have delayed the timing and reduced the scope of our development program, which impacts the average development and redevelopment asset balances qualifying for interest and other carry cost capitalization. During the three months ended September 30, 2011, we did not capitalize interest on six of our seven development pipeline properties with an aggregate cost basis of approximately $147.8 million , as it was determined these projects did not qualify for interest and other carry cost capitalization under GAAP. As of September 30, 2011 , our development pipeline included 110.2 gross acres of land with an aggregate cost basis of approximately $267.5 million . While in recent periods we have delayed the timing and reduced the scope of our development program activity as a result of economic conditions in our submarkets, we continue to proactively evaluate development and redevelopment opportunities throughout the West Coast. In addition, we plan to continue to focus on enhancing the entitlements for our existing development land pipeline, and performing additional activities to prepare for the time when development will again be economically attractive.

We also plan to continue to evaluate other redevelopment opportunities within our property portfolio.

Incentive Compensation . Our Executive Compensation Committee determines compensation, including equity and cash incentive programs, for our executive officers in accordance with the terms and conditions of applicable agreements and incentive award programs. The programs approved by the Executive Compensation Committee have historically provided for equity and cash incentive compensation to be earned by our executive officers based on the attainment of certain performance measures, including financial, operating, development and other targets. Incentive compensation for our executive officers for 2011 has been structured to allow the Executive Compensation Committee to evaluate a variety of key factors and metrics at the end of the year and make a determination of incentive compensation for executive officers based on the Company's and management's overall performance. As a result, accrued incentive compensation and compensation expense for future incentive compensation awards will be affected by our operating and development performance, financial results, the performance of the trading price of the Company's common stock, market conditions and other performance conditions. Consequently, we cannot predict the amounts that will be recorded in future periods related to such incentive compensation.

Share-Based Compensation . As of September 30, 2011 , there was $5.7 million of total unrecognized compensation cost related to outstanding nonvested shares of restricted common stock and nonvested RSUs issued under share-based compensation arrangements. That cost is expected to be recognized over a weighted-average period of 1.6 years. The $5.7 million of unrecognized compensation cost does not reflect the future compensation cost for any potential share-based awards that may be issued based on the Company's and management's performance in 2011. Share-based compensation expense for future incentive compensation awards will be affected by our operating and development performance, financial results, the performance of the trading price of the Company's common stock, and market conditions. Consequently, we cannot predict the amounts that will be recorded in future periods for such share-based awards. See Note 9 to our consolidated financial statements included in this report for additional information regarding our share-based incentive compensation plan.

Current Regional Information

Although real estate fundamentals continue to be challenging in many of our regional submarkets, we have started to see a general increase in occupancy across our portfolio, and we have generally seen a modest decrease in vacancy rates and positive net absorption across many of our regional submarkets as well as a stabilization in rental rates and lease concession packages.

Los Angeles and Ventura Counties. Our Los Angeles and Ventura Counties stabilized office portfolio of 3.0 million rentable square feet was 84.1% occupied with approximately 472,400 available rentable square feet as of September 30, 2011 compared to 89.3% occupied with approximately 328,800 available rentable square feet as of December 31, 2010 . The decrease in occupancy is primarily attributable to 205,000 of rentable square feet related to a lease with one tenant in buildings along the 101-Corridor in Ventura County. The tenant vacated the properties upon expiration of the lease.

As of September 30, 2011 , leases representing an aggregate of approximately 62,600 and 188,800 rentable square feet are scheduled to expire in this region during the remainder of 2011 and in 2012, respectively. The aggregate rentable square feet under the leases scheduled to expire in this region during the remainder of 2011 and in 2012 represents approximately 1.8% of our occupied rentable square feet and 2.1% of our annualized base rental revenues in our total stabilized portfolio. As of September 30, 2011 , we have leased approximately 86,800 rentable square feet in this region that was vacant at September 30, 2011 . The new leases are scheduled to commence during the fourth quarter of 2011.

San Diego County. Our San Diego County stabilized office portfolio of 5.4 million rentable square feet was 92.6% occupied with approximately 402,000 available rentable square feet as of September 30, 2011 compared to 86.4% occupied with approximately 744,300 available rentable square feet as of December 31, 2010 .

No leases are scheduled to expire during the remainder of 2011 and leases representing an aggregate of approximately 465,200 rentable square feet are scheduled to expire in 2012 in this region. The aggregate rentable square feet under leases scheduled to expire in this region in 2012 represents approximately 3.3% of our occupied rentable square feet and 3.6% of our annualized base rental revenues in our total stabilized portfolio.

Orange County. As of September 30, 2011 , our Orange County stabilized industrial portfolio of 3.4 million rentable square feet was 100.0% occupied compared to 93.5% occupied with approximately 220,100 available rentable square feet as of December 31, 2010 .

Our Orange County stabilized office portfolio of approximately 540,700 rentable square feet was 91.4% occupied with approximately 46,600 available rentable square feet as of September 30, 2011 compared to 93.1% occupied with approximately 37,300 available rentable square feet as of December 31, 2010 .

No leases are scheduled to expire during the remainder of 2011 and leases representing an aggregate of approximately 381,900 rentable square feet are scheduled to expire in 2012 in this region. The aggregate rentable square feet under leases scheduled to expire in 2012 represents approximately 2.7% of our occupied rentable square feet and 0.9% of our annualized base rental revenues in our total stabilized portfolio. Of the 381,900 rentable square feet scheduled to expire in 2012, approximately 355,000 rentable square feet is industrial space.

San Francisco Bay Area. As of September 30, 2011 , our San Francisco Bay Area stabilized office portfolio of 1.7 million rentable square feet was 95.4% occupied with approximately 80,000 available rentable square feet, compared to 84.3% occupied with approximately 188,900 available rentable square feet as of December 31, 2010 . The increase in occupancy is primarily attributable to three leases encompassing approximately 143,800 rentable square feet that commenced during the first three quarters of 2011. Additionally, during the nine months ended September 30, 2011, we have acquired three buildings in the San Francisco Bay Area encompassing approximately 531,300 rentable square feet. These three buildings were approximately 92.7% occupied as of September 30, 2011. See Note 2 to our consolidated financial statements included in this report for additional information regarding our 2011 acquisitions.

As of September 30, 2011 , leases representing an aggregate of approximately 800 and 56,600 rentable square feet are scheduled to expire during the remainder of 2011 and in 2012, respectively. The aggregate rentable square feet under leases scheduled to expire in this region during the remainder of 2011 and in 2012 represents approximately 0.4% of our occupied rentable square feet and 0.6% of our annualized base rental revenues in our total stabilized portfolio.

Greater Seattle. As of September 30, 2011 , our Greater Seattle stabilized office portfolio of 0.9 million rentable square feet was 90.2% occupied with approximately 87,300 available rentable square feet as of September 30, 2011 compared to being 100.0%

occupied as of December 31, 2010 . The decrease in occupancy is primarily attributable to the acquisitions of five office buildings encompassing approximately 768,400 rentable square feet during the nine months ended September 30, 2011 that were 88.6% occupied at September 30, 2011 .

As of September 30, 2011 , leases representing an aggregate of approximately 3,100 and 52,600 rentable square feet are scheduled to expire during the remainder of 2011 and in 2012, respectively. The aggregate rentable square feet under leases scheduled to expire in this region during the remainder of 2011 and in 2012 represents approximately 0.4% of our occupied rentable square feet and 0.3% of our annualized base rental revenues in our total stabilized portfolio.

Results of Operations

Management internally evaluates the operating performance and financial results of our portfolio based on Net Operating Income for the consolidated portfolio. We define “Net Operating Income (Loss)” as operating revenues (rental income, tenant reimbursements, and other property income) less operating expenses (property expenses, real estate taxes, provision for bad debts, and ground leases). The Net Operating Income information presented within this Management's Discussion and Analysis of Financial Condition and Results of Operations is the same Net Operating Income information disclosed in our segment information in Note 13 to our consolidated financial statements.

Net Operating Income increased $12.7 million , or 22.5% , for the three months ended September 30, 2011 as compared to the three months ended September 30, 2010 primarily resulting from:


•	An increase of $11.7 million attributable to the ten office buildings we acquired during 2010 and the nine office buildings we acquired during the nine months ended September 30, 2011 (the “Acquisitions Portfolio”);


•	An increase of $1.4 million attributable to the properties owned and stabilized as of January 1, 2010 and still owned and stabilized as of September 30, 2011 (the “Core Portfolio”) primarily as a result of:


▪	An increase in rental income of $2.5 million primarily resulting from an increase in average occupancy of 6.3%, from 86.0% for the three months ended September 30, 2010 , to 92.3% for the three months ended September 30, 2011 ;


▪	An offsetting decrease in tenant reimbursements of $0.7 million primarily resulting from the resetting of base year expense levels for recent lease renewals and reduced tenant reimbursement revenue attributable to one tenant that vacated one of our buildings at the end of their lease;


▪	An increase to Net Operating Income of $0.7 million resulting from a decrease in real estate taxes as a result of successful property tax appeals and lower than expected supplemental tax increases;


•	A decrease to Net Operating Income of approximately $1.2 million resulting from:


•	The reversal of $0.6 million of provision for bad debts during the three months ended September 30, 2010 resulting from the settlement of outstanding litigation at one of our properties;


•	The recognition of $0.6 million in other property income during the three months ended September 30, 2010 as a result of a lease termination fee; and


•	An offsetting decrease of $0.5 million generated by one office building that was moved from the stabilized portfolio to the redevelopment portfolio during the three months ended September 30, 2010 and two office buildings that were moved to the redevelopment portfolio from the stabilized portfolio upon commencement of redevelopment in 2011 (the "Redevelopment Properties").

Other Expenses and Income

General and Administrative Expenses

General and administrative expenses decreased $0.9 million , or 12.6% , for the three months ended September 30, 2011 compared to the three months ended September 30, 2010 primarily as a result of a net decrease in compensation expense resulting from:


•	A decrease in share-based compensation expense (see Note 9 to our consolidated financial statements for more information); and


•	An adjustment to decrease our deferred compensation plan liability to fair value (see Note 12 to our consolidated financial statements included in this report and the discussion under the caption — Interest Income and Other Net Investment Gains below for more information).

These decreases were partially offset by an increase in compensation expense associated with the growth of the Company primarily as a result of the ongoing acquisition activities.

Depreciation and Amortization

Depreciation and amortization increased by $6.2 million , or 20.7% , for the three months ended September 30, 2011 compared to the three months ended September 30, 2010 , primarily related to the Acquisitions Portfolio.

Interest Income and Other Net Investment Gains

Total interest income and other net investment gains decreased by approximately $0.3 million , or 91.1% , for the three months ended September 30, 2011 compared to the three months ended September 30, 2010 , primarily as a result of a decrease in the fair value of the marketable securities held in connection with our deferred compensation plan (see Note 12 to our consolidated financial statements included in this report for additional information), partially offset by interest income and other non-property related gains. The decrease to interest income and other net investment gains resulting from the decrease in the fair value of the marketable securities offsets the decrease in compensation expense discussed in the general and administrative expenses section above.

Interest Expense

The following table sets forth our gross interest expense, including debt discounts/premiums and loan cost amortization, net of capitalized interest for the three months ended September 30, 2011 and 2010 :



	2011			2010			Dollar Change		Percentage Change
	($ in thousands)
Gross interest expense	$	26,449		$	18,543		$	7,906	42.6	%
Capitalized interest	(2,398		)	(2,690		)	292		(10.9	)%
Interest expense	$	24,051		$	15,853		$	8,198	51.7	%

Gross interest expense, before the effect of capitalized interest, increased $7.9 million , or 42.6% , for the three months ended September 30, 2011 compared to the three months ended September 30, 2010 resulting from an increase in our average outstanding debt balances primarily as a result of our acquisition activity.

Capitalized interest decreased $0.3 million , or 10.9% , for the three months ended September 30, 2011 compared to the three months ended September 30, 2010 primarily as a result of a decrease in our weighted-average effective rate from approximately 6.4% to 6.0%, and, to a lesser extent, as a result of a decrease in our average development and redevelopment asset balances qualifying for interest capitalization.

Net Operating Income increased $40.2 million , or 25.9% , for the nine months ended September 30, 2011 as compared to the nine months ended September 30, 2010 primarily resulting from:


•	An increase of $37.2 million attributable to the Acquisitions Portfolio;


•	An increase of $7.0 million attributable to the Core Portfolio primarily as a result of:


▪	An increase in rental income of $8.2 million primarily resulting from an increase in average occupancy of 6.8%, from 84.7% for the nine months ended September 30, 2010 , to 91.5% for the nine months ended September 30, 2011 ;


•	A decrease to Net Operating Income of approximately $1.2 million resulting from:


•	The reversal of $0.6 million of provision for bad debts during the nine months ended September 30, 2010 related to the settlement of outstanding litigation at one of our properties. The remaining year over year increase in the provision for bad debts resulted from changes in our estimates of the collectibility of receivables from certain watchlist tenants; and


•	The recognition of $0.6 million in other property income during the nine months ended September 30, 2010 related to a lease termination fee; and


•	An offsetting decrease of $4.0 million primarily attributable to the Redevelopment Properties that were removed from the stabilized portfolio upon commencement of redevelopment.

Other Expenses and Income

General and Administrative Expenses

General and administrative expenses decreased $0.7 million , or 3.5% , for the nine months ended September 30, 2011 compared to the nine months ended September 30, 2010 primarily as a result of a net decrease in compensation expense resulting from:


•	A decrease in share-based compensation expense (see Note 9 to our consolidated financial statements for more information); and


•	An adjustment to decrease our deferred compensation plan liability to fair value (see Note 12 to our consolidated financial statements included in this report and the discussion under the caption — Interest Income and Other Net Investment Gains below for more information).

These decreases were partially offset by an increase in compensation expense associated with the growth of the Company primarily as a result of the ongoing acquisition activities.

Depreciation and Amortization

Depreciation and amortization increased by $23.1 million , or 31.1 %, for the nine months ended September 30, 2011 compared to the nine months ended September 30, 2010 , primarily related to the Acquisitions Portfolio.

Interest Income and Other Net Investment Gains

Total interest income and other net investment gains decreased by approximately $0.4 million , or 61.3% , for the nine months ended September 30, 2011 compared to the nine months ended September 30, 2010 , primarily as a result of a decrease in the fair value of the marketable securities held in connection with our deferred compensation plan (see Note 12 to our consolidated financial statements included in this report for additional information), partially offset by interest income and other non-property related gains. The decrease to interest income and other net investment gains resulting from the decrease in the fair value of the marketable securities offsets the decrease in compensation expense discussed in the general and administrative expenses section above.

Interest Expense

The following table sets forth our gross interest expense, including debt discounts/premiums and loan cost amortization, net of capitalized interest, for the nine months ended September 30, 2011 and 2010 :



	2011			2010			Dollar Change		Percentage Change
	($ in thousands)
Gross interest expense	$	72,597		$	48,980		$	23,617	48.2	%
Capitalized interest	(6,442		)	(8,083		)	1,641		(20.3	)%
Interest expense	$	66,155		$	40,897		$	25,258	61.8	%

Gross interest expense, before the effect of capitalized interest, increased $23.6 million , or 48.2% , for the nine months ended September 30, 2011 compared to the nine months ended September 30, 2010 resulting from an increase in our average outstanding debt balances primarily as a result of our acquisition activity.

Capitalized interest decreased $1.6 million , or 20.3% , for the nine months ended September 30, 2011 compared to the nine months ended September 30, 2010 primarily attributable to a decrease in our average development and redevelopment asset balances qualifying for interest capitalization.

Liquidity and Capital Resources of the Company

In this "Liquidity and Capital Resources of the Company" section, the term the "Company" refers only to Kilroy Realty Corporation on an unconsolidated basis, and excludes the Operating Partnership and all other subsidiaries.

The Company's business is operated primarily through the Operating Partnership. Distributions from the Operating Partnership are the Company's source of capital. The Company believes the Operating Partnership's sources of working capital, specifically its cash flow from operations and borrowings available under its Credit Facility, are adequate for it to make its distribution payments to the Company and, in turn, for the Company to make its dividend payments to its preferred and common stockholders. Cash flows from operating activities generated by the Operating Partnership for the three and nine months ended September 30, 2011 were sufficient to cover the Company's payment of cash dividends to its stockholders. However, there can be no assurance that the Operating Partnership's sources of capital will continue to be available at all or in amounts sufficient to meet its needs, including its ability to make distributions to the Company. The unavailability of capital could adversely affect the Operating Partnership's ability to make distributions to the Company, which would in turn, adversely affect the Company's ability to pay cash dividends to its stockholders.

The Company is a well-known seasoned issuer with an effective shelf registration statement for the public issuance of preferred or common equity securities and guarantees of debt securities, and for the public issuance by the Operating Partnership of debt securities. As circumstances warrant, the Company may issue securities from time to time on an opportunistic basis, depending upon market conditions and available pricing. When the Company receives proceeds from preferred or common equity issuances, it is required by the Operating Partnership's partnership agreement to contribute the proceeds from its equity issuances to the Operating Partnership in exchange for corresponding interest in preferred or common partnership units of the Operating Partnership. The Operating Partnership may use the proceeds to repay debt, including borrowings under its Credit Facility, develop new or existing properties, to make acquisitions of properties, portfolios of properties, or for general corporate purposes.

As the sole general partner with control of the Operating Partnership, the Company consolidates the Operating Partnership for financial reporting purposes, and the Company does not have significant assets other than its investment in the Operating Partnership. Therefore, the assets and liabilities and the revenues and expenses of the Company and the Operating Partnership are substantially the same on their respective financial statements. The section entitled "Liquidity and Capital Resources of the Operating Partnership" should be read in conjunction with this section to understand the liquidity and capital resources of the Company on a consolidated basis and how the Company is operated as a whole.

Distribution Requirements

The Company is required to distribute 90% of its taxable income (excluding capital gains) on an annual basis to maintain qualification as a REIT for federal income tax purposes, and is required to pay tax at regular corporate rates to the extent it distributes less than 100% of its taxable income (including capital gains). While historically the Company has satisfied its distribution requirement by making cash distributions to its stockholders, for distributions with respect to taxable years ending on or before December 31, 2011, IRS guidance allows the Company to satisfy up to 90% of this requirement through the distribution of shares of the Company's common stock, if certain conditions are met. The Company intends to continue to make, but has not committed to make, regular quarterly cash distributions to common stockholders and common unitholders from cash flow from operating activities. All such distributions are at the discretion of the board of directors. The Company has historically distributed amounts in excess of our taxable income resulting in a return of capital to its stockholders and the Company currently believes it has the ability to maintain distributions at the 2010 levels to meet its REIT requirements for 2011. The Company considers market factors and its performance in addition to REIT requirements in determining our distribution levels. In addition, one of the covenants contained within the Credit Facility prohibits the Company from paying dividends in excess of 95% of Funds From Operations ("FFO").

On September 15, 2011, the Board of Directors declared a regular quarterly cash dividend of $0.35 per common share payable on October 17, 2011 to stockholders of record on September 30, 2011 and caused a $0.35 per Operating Partnership unit cash distribution to be paid in respect of the Operating Partnership's common limited partnership interests, including those owned by the Company.

On September 15, 2011, the Board of Directors declared a dividend of $0.4875 per share on the Company's Series E Preferred Stock and a dividend of $0.46875 per share on the Company's Series F Preferred Stock for the period commencing on and including August 15, 2011 and ending on and including November 14, 2011. The Company is also required to make quarterly cash distributions to the 7.45% Series A Preferred unitholders of $0.7 million, payable on November 15, 2011.

Capitalization

As of September 30, 2011 , our total debt as a percentage of total market capitalization was 46.0% and the total debt and liquidation value of our preferred equity as a percentage of total market capitalization was 51.1% , which was calculated based on the closing price per share of the Company's common stock of $31.30 on September 30, 2011 as shown in the table below.

Liquidity and Capital Resources of the Operating Partnership

In this "Liquidity and Capital Resources of the Operating Partnership" section, the terms "we," "our," and "us" refer to the Operating Partnership or the Company, as the context requires.

General

Our primary liquidity sources and uses are as follows:

Liquidity Sources


•	Net cash flow from operations;


•	Borrowings under the Credit Facility;


•	Proceeds from additional secured or unsecured debt financings;


•	Proceeds from public or private issuance of debt or equity securities; and


•	Proceeds from the disposition of nonstrategic assets.

Liquidity Uses


•	Property or undeveloped land acquisitions;


•	Property operating and corporate expenses;


•	Capital expenditures, tenant improvement and leasing costs;


•	Debt service and principal payments, including debt maturities;


•	Distributions to common and preferred security holders;


•	Development and redevelopment costs; and


•	Outstanding debt repurchases.

General Strategy

Our general strategy is to maintain a conservative balance sheet with a top credit profile and to maintain a capital structure that allows for financial flexibility and diversification of capital resources. We manage our capital structure to reflect a long−term investment approach and utilize multiple sources of capital to meet our long−term capital requirements. We believe that our current projected liquidity requirements for the next twelve-month period, as set forth above under the caption “ —Liquidity Uses,” will be satisfied using a combination of the liquidity sources listed above. We believe our conservative leverage and staggered debt maturities provide us with financial flexibility and enhances our ability to obtain additional sources of liquidity if necessary, and, therefore, we are well−positioned to refinance or repay maturing debt and to pursue our strategy of seeking attractive acquisition opportunities, which we may finance, as necessary, with future public and private issuances of debt and equity securities or dispositions of non-strategic assets.

2011 Financing Activities


•	In November 2011, the Operating Partnership used borrowings under the Credit Facility to repay a secured mortgage loan with an outstanding principal balance of $52.0 million that was scheduled to mature in April 2012.


•	In October 2011, the Operating Partnership used borrowings under the Credit Facility to repay a secured mortgage loan with an outstanding principal balance of $68.7 million that was scheduled to mature in December 2011.


•	In July 2011, we commenced a periodic stock offering program under which we may sell up to $200.0 million aggregate gross sales price of the Company's common stock from time to time. We have not issued any stock under this program as of the date of this report (see "- Liquidity Sources" below for additional information).


•	In July 2011, the Operating Partnership issued $325.0 million in aggregate principal amount of 4.80% unsecured senior notes due July 15, 2018 (see Note 5 to our consolidated financial statements included in this report for additional information).


•	In June 2011, the Operating Partnership amended the terms of the Credit Facility to, among other things, extend the maturity date to August 2015, reduce the interest rate to an annual rate of LIBOR plus 1.750% and reduce the facility fee to an annual rate of 0.35% (see Note 5 to our consolidated financial statements included in this report for additional information).


•	In April 2011, the Operating Partnership assumed secured debt with a principal balance of $30.0 million in conjunction with the acquisition of four office buildings in Kirkland, Washington (see Note 5 to our consolidated financial statements included in this report for additional information).

•

In April 2011, the Company completed an underwritten public offering of 6,037,500 shares of its common stock. The net offering proceeds, after deducting underwriting discounts and commissions and offering expenses, of approximately $221.0 million were contributed to the Operating Partnership (see Notes 7 and 8 to our consolidated financial statements included in this report for additional information).

•

In January 2011, the Operating Partnership borrowed $135.0 million under a mortgage loan. The mortgage loan is secured by one property in San Francisco, bears interest at an annual rate of 4.27%, requires interest-only payments for the first two years with a 30-year amortization schedule thereafter, and is scheduled to mature on February 1, 2018 (see Note 5 to our consolidated financial statements included in this report for additional information).

Liquidity Sources

Credit Facility

In June 2011, we amended the terms of our Credit Facility, among other things, to extend the maturity date and reduce the interest rate and facility fee. The following table summarizes the terms of our Credit Facility as of December 31, 2010 and as amended as of September 30, 2011 :



	September 30, 2011			December 31, 2010
	(in thousands)

Maturity date ⁽⁵⁾	August 2015			August 2013

________________________

(1) As of September 30, 2011 there were no borrowings outstanding under the Credit Facility.

(2) We may elect to borrow, subject to lender approval, up to an additional $200 million under an accordion feature under the terms of the Credit Facility.

(4) The facility fee is paid on a quarterly basis and is calculated based on the total borrowing capacity. In addition to the facility fee, we also incurred debt origination and legal costs of approximately $5.0 million when we entered into the Credit Facility in 2010 and an additional $3.3 million when we amended the Credit Facility in 2011. The unamortized balance of these costs will be amortized as additional interest expense over the extended term of the Credit Facility.

(5) Under the original and amended terms of the Credit Facility, we may exercise an option to extend the maturity date by one year.

Periodic Stock Offering Program

In July 2011, we commenced a periodic stock offering program under which we may sell up to $200 million aggregate gross sales price of the Company's common stock from time to time. As of the date of this report, no shares have been sold under the program. Actual sales will depend upon a variety of factors including but not limited to market conditions, the trading price of the Company's common stock, and our capital needs. We have no obligation to sell shares under this program.

Capital Recycling Program

As part of our current strategy, we intend to dispose of mature office and industrial assets and then use the proceeds to fund potential acquisitions, to finance development and redevelopment expenditures, to potentially repay long-term debt and general corporate purposes. As part of this strategy, we intend, when practical, to enter into Section 1031 Exchanges. During the nine months ended September 30, 2011 , we disposed of two office buildings in one transaction for approximately $23.9 million . At September 30, 2011 , the net cash proceeds from this disposition were temporarily being held by a qualified intermediary, at our direction, for the purpose of facilitating a potential Section 1031 Exchange. As part of our capital recycling program strategy, we are in various stages of negotiation for the disposition of four additional properties with an aggregate sales price of approximately $205 million . In addition, we believe that we could potentially dispose of additional properties over the next 12 to 18 months, depending on market conditions. However, we cannot provide assurance that we will consummate any of these possible dispositions or, if we do, that the anticipated proceeds from these dispositions will not be less, perhaps substantially, than the foregoing amounts or that these dispositions will be completed as part of a Section 1031 exchange.

Exchangeable Notes, Unsecured Senior Notes, and Secured Debt

The aggregate principal amount of our Exchangeable Notes, unsecured senior notes, and secured debt of the Operating Partnership outstanding as of September 30, 2011 was as follows:

Also includes the $30.0 million gross aggregate principal amount of the loan due in April 2015 before the effect of the unamortized premium of approximately $0.9 million as of September 30, 2011 .


(2)	Subsequent to September 30, 2011 , we repaid two secured mortgages with principal balances of $68.7 million due in December 2011 and $52.0 million due in April 2012. These repayments were financed with proceeds from the Credit Facility.

(3) Represents gross aggregate principal amount before the effect of the unamortized discount of approximately $15.4 million as of September 30, 2011 .

(4) Represents gross aggregate principal amount before the effect of the unamortized discount of approximately $2.5 million as of September 30, 2011 .

(5) As of September 30, 2011 the Credit Facility was our only variable-rate debt. There were no borrowings outstanding under the Credit Facility at September 30, 2011 . As of the date of this report, we had $165.0 million in outstanding borrowings under the Credit Facility.


(6)	The information in the table above reflects our projected interest rate obligations for our fixed-rate payments based on the contractual interest rates, interest payment dates, and scheduled maturity dates.

(7)

One of our ground lease obligations is subject to a fair market value adjustment every five years; however, the lease includes ground rent subprotection and infrastructure rent credits which currently limit our annual rental obligations to $1.0 million . The contractual obligations for that ground lease included above assumes the lesser of $1.0 million or annual lease rental obligation in effect as of September 30, 2011 . Another one of our ground lease obligations includes a component which is based on the percentage of gross income that exceeds the minimum ground rent. The minimum rent is subject to increases every five years based on 50% of the average annual percentage rent for the previous five years. Currently gross income does not exceed the threshold requiring us to pay percentage rent. The contractual obligations for that ground lease included above assumes the annual lease rental obligation in effect as of September 30, 2011 .


(8)	Amounts represent commitments under signed leases and contracts for operating properties, excluding tenant-funded tenant improvements. The timing of these expenditures may fluctuate.


(9)	Amounts represent contractual commitments for redevelopment projects under construction at September 30, 2011 . The timing of these expenditures may fluctuate based on the ultimate progress of construction.

Other Potential Liquidity Uses

In 2010 we acquired ten properties for approximately $637.6 million in cash and through September 30, 2011 we have acquired nine properties for approximately $481.8 million in cash, all of which we funded through various capital raising activities, and in selected instances, the assumption of existing indebtedness. We continually evaluate acquisition opportunities as they arise. As a result, we typically have one or more potential acquisitions under consideration that are in varying stages of negotiation and due diligence review, or under contract, at any point in time. We expect that any material acquisitions will be funded with borrowings

under our Credit Facility, the public or private issuance of debt or equity securities, or through the disposition of assets under our capital recycling program.

We may seek to repurchase Exchangeable Notes depending on prevailing market conditions, our liquidity requirements, and other factors.

Factors That May Influence Future Sources of Capital and Liquidity of the Company and the Operating Partnership

We continue to evaluate sources of financing for our business activities, including borrowings under the Credit Facility, issuance of public and private equity securities, unsecured debt and fixed-rate secured mortgage financing. However, the Operating Partnership's ability to obtain new financing or refinance existing borrowings on favorable terms could be impacted by various factors including the state of economic conditions, significant tenant defaults, a decline in the demand for office or industrial properties, a decrease in market rental rates or market values of real estate assets in our submarkets, and the amount of future borrowings. These events could result in the following:


•	Decreases in our cash flows from operations, which could create further dependence on our Credit Facility;


•	An increase in the proportion of variable-rate debt, which could increase our sensitivity to interest rate fluctuations in the future;


•	A decrease in the value of our properties, which could have an adverse effect on the Operating Partnership's ability to incur additional debt, refinance existing debt at competitive rates, or comply with its existing debt obligations; and


•	A decrease in the value of our stock, which could impact our ability to issue equity.

In addition to the factors noted above, the Operating Partnership's credit ratings are subject to ongoing evaluation by credit rating agencies and may be changed or withdrawn by a rating agency in the future if, in its judgment, circumstances warrant. In the event that the Operating Partnership's credit ratings are downgraded, we may incur higher borrowing costs and may experience difficulty in obtaining additional financing or refinancing existing indebtedness.

Debt Covenants

The Credit Facility, unsecured senior notes, and certain other secured debt arrangements contain covenants and restrictions requiring us to meet certain financial ratios and reporting requirements. Key existing financial covenants and their covenant levels include:



Credit Facility (as defined in the Credit Agreement):	Covenant Level	Actual Performance at September 30, 2011
Total debt to total asset value	less than 60%	39%
Fixed charge coverage ratio	greater than 1.5x	2.3x
Unsecured debt ratio	greater than 1.67x	2.34x
Unencumbered asset pool debt service coverage	greater than 2.0x	3.5x


Unsecured Senior Notes due 2015, 2018 and 2020 (as defined in the Indentures):
Total debt to total asset value	less than 60%	45%
Interest coverage	greater than 1.5x	2.8x
Secured debt to total asset value	less than 40%	12%
Unencumbered asset pool value to unsecured debt	greater than 150%	234%

The Operating Partnership was in compliance with all its debt covenants as of September 30, 2011 . Our current expectation is that the Operating Partnership will continue to meet the requirements of its debt covenants in both the short and long term. However, in the event of a renewed economic slow down or continued volatility in the credit markets, there is no certainty that the Operating Partnership will be able to continue to satisfy all the covenant requirements.

Consolidated Historical Cash Flow Summary

Our historical cash flow activity for the nine months ended September 30, 2011 as compared to the nine months ended September 30, 2010 is as follows:



	Nine Months Ended September 30,
	2011			2010			Dollar Change			Percentage Change
	($ in thousands)
Net cash provided by operating activities	$	114,065		$	94,928		$	19,137		20.2	%
Net cash used in investing activities	(553,215		)	(434,655		)	(118,560		)	27.3	%
Net cash provided by financing activities	439,791			338,157			101,634			30.1	%

Operating Activities

Our cash flows from operations depends on numerous factors including the occupancy level of our portfolio, the rental rates achieved on our leases, the collectability of rent and recoveries from our tenants, the level of operating expenses, the impact of property acquisitions and related financing activities, and other general and administrative costs. Our net cash provided by operating activities increased by $19.1 million , or 20.2% , for the nine months ended September 30, 2011 compared to the nine months ended September 30, 2010 primarily as a result of an increase in cash Net Operating Income generated primarily from our Acquisitions Portfolio partially offset by increased interest expense attributable to the increase in our average outstanding debt balances as a result of our acquisition activity. See additional information under the caption "−Rental Operations."

Investing Activities

Our net cash used in investing activities is generally used to fund property acquisitions, recurring and nonrecurring capital expenditures for our operating properties, and development and redevelopment projects. Our net cash used in investing activities increased $118.6 million , or 27.3% , for the nine months ended September 30, 2011 compared to the nine months ended September 30, 2010 . This net increase was primarily attributable to our increased acquisition activity and the $11.0 million in non-refundable escrow deposits, subject only to the failure of satisfaction of conditions precedent to the closing, made during the nine months ended September 30, 2011 for potential future acquisitions.

Financing Activities

Our net cash provided by financing activities is generally impacted by our capital raising activities net of dividends and distributions paid to common and preferred security holders. Net cash provided by financing activities increased by $101.6 million , or 30.1% , for the nine months ended September 30, 2011 compared to the nine months ended September 30, 2010 , and was primarily attributable to the following:


•	A net increase of approximately $105.8 million provided by our various capital raising activities and


•	An offsetting decrease of $8.6 million as a result of the dividends paid on the 6.0 million common shares we issued in our April 2011 equity offering.

Consolidated Off-Balance Sheet Arrangements

As of September 30, 2011 and as of the date this report was filed, we did not have any off-balance sheet transactions, arrangements, or obligations, including contingent obligations.

Non-GAAP Supplemental Financial Measure: Funds From Operations

We calculate 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 or loss calculated in accordance with GAAP, excluding extraordinary items, as defined by GAAP, and gains and losses from sales of depreciable operating property, plus real estate-related depreciation and amortization (excluding amortization of deferred financing costs and depreciation of non-real estate assets), and after adjustment for unconsolidated partnerships and joint ventures.

We believe that FFO is a useful supplemental measure of our operating performance. The exclusion from FFO of gains and losses from the sale of operating real estate assets allows investors and analysts to readily identify the operating results of the assets that form the core of our activity and assists in comparing those operating results between periods. Also, because FFO is generally recognized as the industry standard for reporting the operations of REITs, it facilitates comparisons of operating performance to other REITs. However, other REITs may use different methodologies to calculate FFO, and accordingly, our FFO may not be comparable to all other REITs.

Implicit in historical cost accounting for real estate assets in accordance with GAAP is the assumption that the value of real estate assets diminishes predictably over time. Since real estate values have historically risen or fallen with market conditions, many industry investors and analysts have considered presentations of operating results for real estate companies using historical cost accounting alone to be insufficient. Because FFO excludes depreciation and amortization of real estate assets, we believe that FFO along with the required GAAP presentations provides a more complete measurement of our performance relative to our competitors and a more appropriate basis on which to make decisions involving operating, financing, and investing activities than the required GAAP presentations alone would provide.

However, FFO should not be viewed as an alternative measure of our operating performance since it does not reflect either depreciation and amortization costs or the level of capital expenditures and leasing costs necessary to maintain the operating performance of our properties, which are significant economic costs and could materially impact our results from operations.

The following table presents our FFO for the three and nine months ended September 30, 2011 and 2010 :



	Three Months Ended September 30,						Nine Months Ended September 30,
	2011			2010			2011			2010

ITEM 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary market risk we face is interest rate risk. We mitigate this risk by following established risk management policies and procedures. These policies include maintaining prudent amounts of debt, including a greater amount of fixed-rate debt as compared to variable-rate debt in our portfolio, and may include the periodic use of derivative instruments. As of September 30, 2011 and December 31, 2010 , we did not have any interest-rate sensitive derivative assets or liabilities.

Information about our changes in interest rate risk exposures from December 31, 2010 to September 30, 2011 is incorporated herein by reference from "Item 2: Management's Discussion and Analysis of Financial Condition and Results of Operations —Liquidity and Capital Resources of the Operating Partnership."

Market Risk

As of September 30, 2011 , 100.0% of our total outstanding debt of $1.8 billion was subject to interest at fixed rates. We had no floating rate debt as of September 30, 2011 since our only floating rate debt is our Credit Facility and there were no borrowings outstanding under the Credit Facility as of September 30, 2011 . All of our interest rate sensitive financial instruments are held for purposes other than trading purposes.

In general, interest rate fluctuations applied to our variable-rate debt will impact our future earnings and cash flows. Conversely, interest rate fluctuations applied to our fixed-rate debt will generally not impact our future earnings and cash flows, unless such instruments mature or are otherwise terminated and need to be refinanced. However, interest rate fluctuations will impact the fair value of the fixed-rate debt instruments.

With the exception of the Exchangeable Notes and our publicly traded unsecured senior notes, we generally determine the fair value of our fixed-rate debt by performing discounted cash flow analyses using an appropriate market rate. We calculate the market rate by obtaining period-end treasury rates for maturities that correspond to the maturities of our fixed-rate debt and then adding an appropriate credit spread based on information obtained from third-party financial institutions. These credit spreads take into account factors, including but not limited to, our credit profile, the tenure of the debt, amortization period, whether the debt is secured or unsecured, and the loan-to-value ratio of the debt. We determine the fair value of the liability component of our Exchangeable Notes by performing discounted cash flow analysis using an appropriate market interest rate derived from spreads for our publicly traded debt. We determine the fair value of each of our publicly traded unsecured senior notes based on their quoted trading price at the end of the reporting period. See Note 12 to our consolidated financial statements included in this report for additional information on the fair value of our financial assets and liabilities as of September 30, 2011 and December 31, 2010 .

As of September 30, 2011 , we did not have any variable-rate debt since we did not have any outstanding borrowings on our Credit Facility. As of December 31, 2010 , the total outstanding balance of our variable-rate debt included borrowings of $159.0 million and was indexed to LIBOR plus a spread of 2.675% (weighted average interest rate was 2.99% ). Assuming no changes in the outstanding balance of our existing variable-rate debt as of December 31, 2010 , a 100 basis point increase in the LIBOR rate would increase our projected annual interest expense, before the effect of capitalization, by approximately $1.6 million.

The total carrying value of our fixed-rate debt, including our Exchangeable Notes, was approximately $1.8 billion and $1.3 billion as of September 30, 2011 and December 31, 2010 , respectively. The total estimated fair value of our fixed-rate debt was approximately $1.8 billion and $1.3 billion as of September 30, 2011 and December 31, 2010 , respectively. For sensitivity purposes, a 100 basis point increase in the discount rate equates to a decrease in the total fair value of our fixed-rate debt of approximately $67.8 million, or 3.7%, as of September 30, 2011 . Comparatively, a 100 basis point increase in the discount rate equates to a decrease in the total fair value of our fixed-rate debt of approximately $47.2 million, or 3.6%, as of December 31, 2010 .

The above sensitivity analyses do not consider interrelationships between different market movements, which could result in additional changes in the fair value of our debt and Exchangeable Notes, beyond the amounts calculated.
