EXPLANATORY NOTE

This report combines the quarterly report on Form 10-Q for the period ended September 30, 2010 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” 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 terms “the Company,” “we,” “our,” and “us” refer to the Company or the Company and the Operating Partnership together, as the text requires.

The Company is a real estate investment trust, or REIT, and the general partner of the Operating Partnership. As of September 30, 2010, the Company owned an approximate 96.8% common general partnership interest in the Operating Partnership. The remaining approximate 3.2% 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 real estate investment trust, whose only material asset is its ownership of partnership interests of 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 public 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 the assets of the Company either directly or through its subsidiaries, conducts the operations of the business and is structured as a limited partnership with no publicly traded equity. Except for net proceeds from public equity issuances by the Company, which are contributed to the Operating Partnership in exchange for partnership units, the Operating Partnership generates the capital required by the Company’s business through the Operating Partnership’s operations, by the Operating Partnership’s direct or indirect incurrence of indebtedness or through the issuance of partnership units.

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 at the Company and the Operating Partnership levels 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 investor 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:

• Secured and Unsecured Debt of the Company and Secured and Unsecured Debt of the Operating Partnership;

• Stockholders’ Equity of the Company and Partners’ Capital of the Operating Partnership;

• Net (Loss) Income Available to Common Stockholders per Share and Net (Loss) Income Available to Unitholders;

• Pro Forma Results of the Company and Pro Forma Results of the Operating Partnership; and

• Liquidity and Capital Resources in Item 2: Management’s Discussion and Analysis of Financial Condition and Results of Operations.

This report also includes separate Item 4. Controls and Procedures sections and separate Exhibit 31 and 32 certifications for each of the Company and the Operating Partnership in order 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 and 18 U.S.C. §1350.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Nine Months Ended September 30, 2010 and 2009
(unaudited)

1. Organization and Basis of Presentation

Organization

Kilroy Realty Corporation owns, operates, develops, and acquires office and industrial real estate located in California. We qualify and operate as a self-administered real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended. As of September 30, 2010, all but one of our properties are located in Southern California.

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, 2010:


	Number of		Rentable		Number of
	Buildings		Square Feet		Tenants		Percentage Occupied
Office Properties ⁽¹⁾		99		9,809,506		347		84.8	%
Industrial Properties		41		3,654,463		60		90.6	%

Total Stabilized Portfolio		140		13,463,969		407		86.4	%


(1)		Includes one office property acquired in March 2010, one office property acquired in May 2010, and five office properties acquired in June 2010 (see Note 2 for additional information).

Our stabilized portfolio excludes undeveloped land, development and redevelopment properties currently under construction, “lease-up” properties, and one industrial property that we are in the process of repositioning for residential use. 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. As of September 30, 2010, we had no properties that were in the lease-up phase. During the quarter ended September 30, 2010, we received notification that the zoning to allow high density residential improvements on the land underlying the industrial property that we are in the process of repositioning was adopted by the City of Irvine. We are currently evaluating strategic alternatives for this property. During the quarter ended September 30, 2010, we commenced redevelopment on one of our properties that was previously occupied by a single tenant for over 25 years. The property encompasses approximately 300,000 rentable square feet of office space and is located in the El Segundo submarket of Los Angeles county.

We own our interests in all of our Office Properties and Industrial Properties 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. Accordingly, the descriptions of our business, employees, and properties are also descriptions of the business, employees, and properties of the Operating Partnership. Unless the context indicates otherwise, the term “Company” refers to Kilroy Realty Corporation and its consolidated subsidiaries and the term “Operating “Partnership” refers to Kilroy Realty, L.P. and its consolidated subsidiaries. The terms “we”, “our” and “us” refer to the Company or the Company and the Operating Partnership together, as the text requires.

As of September 30, 2010, the Company owned a 96.8% general partnership interest in the Operating Partnership. The remaining 3.2% common limited partnership interest in the Operating Partnership as of September 30, 2010 was owned by certain of our non-affiliated investors and certain directors and officers of the Company (see Note 7). Kilroy Realty Finance, Inc., a wholly-owned subsidiary of the Company, 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. We conduct substantially all of our development activities through Kilroy Services, LLC (“KSLLC”), which is a wholly-owned subsidiary of the Operating Partnership. Unless otherwise indicated, all references to the Company include the Operating Partnership, the Finance Partnership, KSLLC and all wholly-owned subsidiaries of the Company and the Operating Partnership and all references to the Operating Partnership include the Operating Partnership, the Finance Partnership, KSLLC and all wholly-owned subsidiaries of the Operating Partnership.

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 wholly-owned subsidiaries of the Company and the Operating Partnership. 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 Company and the Operating Partnership. All intercompany

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

balances and transactions have been eliminated in the consolidated financial statements. We also consolidate all variable interest entities (“VIE”) when we are deemed to be the primary beneficiary. During the period ended June 30, 2010, we were required to establish a VIE, Kilroy Realty Northside Drive, LLC, to hold the $52.6 million of assets and liabilities purchased and $51.1 million of secured debt, net, assumed in connection with the acquisition of three office buildings in San Diego, California (see Notes 2 and 6). Kilroy Realty Northside Drive, LLC is a bankruptcy-remote VIE, and the assets held by this entity are not available to satisfy the debts and other obligations of the Company or the Operating Partnership.

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, 2010. The interim financial statements for the Company should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2009. The interim financial statements for the Operating Partnership should be read in conjunction with the audited consolidated financial statements and notes there to included in the Operating Partnership’s General Form for Registration of Securities on Form 10 filed with the SEC on August 18, 2010.

Change in Statements of Operations Presentation for the Company

Certain prior period amounts in the Company’s consolidated statement of operations have been reclassified to conform to the current period presentation. We reclassified interest expense to be presented under Other (Expenses) Income in the Company’s consolidated statements of operations for all periods presented. Interest expense had previously been presented under Expenses.

Significant Accounting Policies

Acquisitions

We record the acquired tangible and intangible assets and assumed liabilities of operating property acquisitions at fair value at the acquisition date. The acquired assets and assumed liabilities for an operating property acquisition generally include but are not limited to: land, buildings and improvements, and identified tangible and intangible assets and liabilities associated with in-place leases, including tenant improvements, leasing costs, value of above-market and below-market leases, acquired in-place lease values, and tenant relationships, if any.

The fair value of land is derived from comparable sales of land within the same submarket and/or region. The fair value of buildings and improvements, tenant improvements, and leasing costs are based upon current market replacement costs and other relevant market rate information.

The fair value of the above-market or below-market component of an acquired in-place lease is based upon the present value (calculated using a market discount rate) of the difference between (i) the contractual rents to be paid pursuant to the lease over its remaining term and (ii) management’s estimate of the rents that would be paid using fair market rental rates and rent escalations at the date of acquisition over the remaining term of the lease. The amounts recorded for above-market leases are included in deferred leasing costs and acquisition-related intangibles, net on the balance sheet and are amortized on a straight-line basis as a reduction of rental income over the remaining term of the applicable leases. The amounts recorded for below-market leases are included in deferred revenue and acquisition-related liabilities, net on the balance sheet and are amortized on a straight-line basis as an increase to rental income over the remaining term of the applicable leases.

The fair value of acquired in-place leases is derived based on management’s assessment of lost revenue and costs incurred for the period required to lease the “assumed vacant” property to the occupancy level when purchased. The amount recorded for acquired in-place leases is included in deferred leasing costs and acquisition-related intangibles, net on the balance sheet and amortized as an increase to depreciation and amortization expense over the remaining term of the applicable leases.

We record undeveloped land acquisitions at the purchase price paid and capitalize the associated acquisition costs.

Operating Properties

Operating properties are generally carried at historical cost less accumulated depreciation. Properties held for sale are reported at the lower of the carrying value or the fair value less estimated cost to sell. The cost of operating properties includes the purchase price or development costs of the properties. Costs incurred for the renovation and betterment of the operating properties are capitalized to our investment in that property. Maintenance and repairs are charged to expense as incurred.

When evaluating properties to be held and used for potential impairment, we first evaluate whether there are any indicators of impairment for any of our properties. If any impairment indicators are present for a specific property, we then perform an undiscounted cash flow analysis and compare the net carrying amount of the property to the property’s estimated undiscounted future cash flow over the anticipated holding period. If the estimated undiscounted future cash flow is less than the net carrying amount of the property, we then perform an impairment loss calculation to determine if the fair value of the property is less than the net carrying value of the property. Our impairment loss calculation compares the net carrying amount of the property to the property’s estimated fair value, which may be based on estimated discounted future cash flow calculations or third-party valuations or appraisals. We would recognize an impairment loss if the asset’s net carrying amount exceeds the asset’s estimated fair value. If we were to recognize an impairment loss, the estimated fair value of the asset would become its new cost basis. For a depreciable long-lived asset, the new cost basis would be depreciated (amortized) over the remaining useful life of that asset. We did not record any impairment losses for the periods presented.

Development and Redevelopment Properties

All costs clearly associated with the acquisition, development, and construction of a development or redevelopment property are capitalized as project costs. In addition, the following costs are capitalized as project costs during periods in which activities necessary to get the property ready for its intended use are in progress: pre-construction costs essential to the development of the property, interest, real estate taxes, insurance, and internal compensation and administrative costs that are clearly related to our development or redevelopment activities.

	•		For development and redevelopment properties that are pre-leased, we cease capitalization when revenue recognition commences, which is upon substantial completion of tenant improvements.

	•		For development and redevelopment properties that are not pre-leased, we may not immediately build out the tenant improvements. Therefore we cease capitalization when revenue recognition commences upon substantial completion of the tenant improvements, but in any event not later than one year after the cessation of major construction activities. We also cease capitalization on a development or redevelopment property when activities necessary to get the property ready for its intended use have been suspended.

	•		For development or redevelopment properties with multiple tenants and staged leasing, we cease capitalization and begins depreciation on the portion of the development or redevelopment property for which revenue recognition has commenced.

Once major construction activity has ceased and the development or redevelopment property is in the lease-up phase, the costs capitalized to construction in progress are transferred to land and improvements, buildings and improvements, and deferred leasing costs on our consolidated balance sheets as the historical cost of the property.

2. Acquisitions

During the nine months ended September 30, 2010, we acquired the operating properties listed below from unrelated third parties. Unless otherwise noted, we funded these acquisitions principally with the net proceeds from the issuance of the 6.625% unsecured senior notes due 2020 (see Note 6), the net proceeds from the Company’s public offering of common stock (see Note 8), and borrowings under the unsecured line of credit (see Note 6):

5. Secured and Unsecured Debt of the Company

In this Note 5, the Company refers solely to Kilroy Realty Corporation and not to any of our subsidiaries. The Company itself does not hold any indebtedness. All of our secured and unsecured debt is held directly by the Operating Partnership.

The Company guarantees all the Operating Partnership’s unsecured debt obligations including the unsecured line of credit, the 6.625% unsecured senior notes due 2020, the 6.45% unsecured senior notes due 2014, the 3.25% Exchangeable Notes due 2012 (the “3.25% Exchangeable Notes”) and 4.25% Exchangeable Notes due 2014 (the “4.25% Exchangeable Notes” and, together with the 3.25% Exchangeable Notes the “Exchangeable Notes”). As of September 30, 2010, the Operating Partnership had $0.9 billion of unsecured debt obligations outstanding, before the effect of discounts.

In addition, although the remaining $0.3 billion of the Operating Partnership’s debt is secured and non-recourse to the Company, the Company provides limited customary secured debt guarantees for items such as voluntary bankruptcy, fraud, misapplication of payments, and environmental liabilities.

The Company and the Operating Partnership are both named parties to the capped call option transactions discussed further in Note 6.

Debt Covenants and Restrictions

One of the covenants contained within the $500 million unsecured revolving credit facility (the “New Credit Facility”) prohibits the Company from paying dividends in excess of 95% of funds from operations (“FFO”).

6. Secured and Unsecured Debt of the Operating Partnership

Secured Debt

In January 2010, the Operating Partnership borrowed $71.0 million under a mortgage loan that is scheduled to mature on February 1, 2017. The mortgage loan is secured by five properties, bears interest at an annual rate of 6.51%, and requires monthly principal and interest payments based on a 30-year amortization period. We used a portion of the proceeds to pay off a mortgage loan with an outstanding principal balance of $63.2 million that was scheduled to mature in April 2010. In connection with the closing of this loan, we were refunded the $1.4 million earnest loan deposit we paid to the lender in the fourth quarter of 2009.

In March 2010, the Operating Partnership used borrowings under the unsecured line of credit (the “Credit Facility”) to pay off a secured line of credit with an outstanding principal balance of $33.5 million that was scheduled to mature in April 2010.

In connection with the acquisition of three office buildings at Mission City Corporate Center in June 2010, the Operating Partnership assumed secured debt with a principal balance of $52.0 million that is scheduled to mature on April 1, 2012. This secured debt was recorded at fair value on the date of the acquisition and is shown net of the initial discount at assumption of $0.9 million on the consolidated balance sheets. This discount will be accreted 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 secured debt. The secured debt and the three properties that secure the debt are held in a bankruptcy remote special purpose entity and the properties are not available to satisfy the debts and other obligations of the Company or the Operating Partnership (see Notes 1 and 2). The debt bears contractual interest at a weighted average annual rate of 5.1% and requires monthly interest only payments.

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Unsecured Senior Notes

In May 2010, the Operating Partnership issued unsecured senior notes in a private placement transaction with an aggregate principal balance of $250.0 million that are scheduled to mature in June 2020. On October 5, 2010, the Company commenced an exchange offer of the private unsecured senior notes for registered unsecured senior notes. The terms of the registered unsecured senior notes are substantially identical to the outstanding private unsecured senior notes, except for transfer restrictions and registration rights relating to the outstanding private unsecured senior notes. The exchange offer expires on November 3, 2010, unless extended. We will not receive any additional proceeds as a result of the exchange offer.

The unsecured senior notes require semi-annual interest payments each June and December based on a contractual annual interest rate of 6.625%. The unsecured senior notes are shown net of the initial issuance discount of $2.1 million on the consolidated balance sheets. This discount is accreted 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. We used a portion of the net proceeds to repurchase $150.0 million in aggregate principal balance of the 3.25% Exchangeable Notes. A portion of the net proceeds was used to fund acquisitions during the nine months ended September 30, 2010 (See Note 2).

In August 2010, the Operating Partnership used borrowings under the Credit Facility to repay a portion of our unsecured senior notes, with a principal balance of $61.0 million that matured in August.

Unsecured Line of Credit

In August 2010 the Operating Partnership entered into the New Credit Facility and used borrowings under the New Credit Facility to repay, and then terminate, the Credit Facility . The New Credit Facility has a term of three years plus a one year extension at our option and bears interest at an annual rate of LIBOR plus 2.675%. We may elect to borrow up to an additional $200.0 million under an accordion option subject to bank approval. We expect to use borrowings under the New Credit Facility for general corporate purposes, to fund potential acquisitions, to finance development and redevelopment expenditures, and potentially to repay long-term debt. The following table summarizes the balance and significant terms of the New Credit Facility and Credit Facility as of September 30, 2010 and December 31, 2009, respectively:


	September 30,			December 31,

(1)		Under the terms of the New Credit Facility, we may exercise an option to extend the maturity date by one year.
(2)		In April 2010, we exercised an option to extend the maturity date of the Credit Facility by one year.
(3)		As of September 30, 2010, the New Credit Facility bore interest at an annual rate of LIBOR plus 2.675%. As of December 31, 2009, the Credit Facility bore interest at an annual rate of LIBOR plus 0.85% to 1.35% depending upon our leverage ratio at the time of borrowing.
(4)		As of September 30, 2010, the facility fee for the New Credit Facility was at an annual rate of 0.575%. As of December 31, 2009, the fee for unused funds for the Credit Facility was at an annual rate of 0.15% to 0.20%, depending on the balance of our daily average undrawn balance. In addition, we also incurred debt origination and legal costs of approximately $5 million, which will be amortized as additional interest expense through the contractual maturity date.

Tender Offer for the 3.25% Exchangeable Notes

In June 2010, the Operating Partnership repurchased 3.25% Exchangeable Notes with an aggregate stated principal amount of $150.0 million for approximately $151.1 million in cash, including transaction costs, pursuant to a tender offer. As a result of the transaction, we recorded a net loss on early extinguishment of debt of approximately $4.6 million and charged approximately $2.7 million, representing the amount of the cash repurchase proceeds allocated to the equity component, to additional paid-in capital.

Interest Expense for the Exchangeable Notes

The unamortized discount on the Exchangeable Notes is accreted as additional interest expense from the date of issuance through the maturity date of the applicable Exchangeable Notes. The following table summarizes the total interest expense attributable to the Exchangeable Notes based on the effective interest rates set forth above, before the effect of capitalized interest, for the three and nine months ended September 30, 2010 and 2009:

Interest expense attributable to the Exchangeable Notes	$	4,853	$	5,707	$	18,027	$	17,422

The trading price of the Company’s common stock on the New York Stock Exchange (“NYSE”) was below the exchange price of the then-outstanding Exchangeable Notes as of both September 30, 2010 and December 31, 2009 and, therefore, the exchange option was out-of-the-money at these dates.

Capped Call Transactions

In connection with each of the Exchangeable Notes offerings, we entered into capped call option transactions to mitigate the dilutive impact to us of the potential conversion of the Exchangeable Notes. The following table summarizes our capped call option positions as of September 30, 2010 and December 31, 2009:


	3.25% Exchangeable Notes⁽¹⁾			4.25% Exchangeable Notes⁽²⁾

(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.
(3)		Subsequent to the repurchase of $150.0 million of aggregate stated principal of the 3.25% Exchangeable Notes, we had the above referenced outstanding capped calls.

Debt Covenants and Restrictions

The New Credit Facility, the unsecured senior notes, and certain other secured debt arrangements contain covenants and restrictions requiring the Company 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, a minimum unencumbered asset pool, a debt service coverage ratio, and a minimum unencumbered debt yield. (see Note 5). 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 were in compliance with all of our debt covenants as of September 30, 2010.

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 balance sheet date. The aggregate value upon redemption of the then-outstanding noncontrolling common units was $57.2 million and $53.6 million as of September 30, 2010 and December 31, 2009, 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.

8. Stockholders’ Equity of the Company

Issuance of Common Stock

In April 2010, the Company completed an underwritten public offering of 9,200,000 shares of its common stock. The net offering proceeds, after deducting underwriting discounts and commissions and offering expenses, were approximately $299.8 million, which the Company contributed to the Operating Partnership in exchange for 9,200,000 common units. We used a portion of the net proceeds from the offering to fund acquisitions, repay borrowings on the Credit Facility, and for general corporate purposes.

9. Partners’ Capital of the Operating Partnership

Issuance of Common Units

In April 2010, the Company completed an underwritten public offering of 9,200,000 shares of the Company’s common stock. The net offering proceeds, after deducting underwriting discounts and commissions and offering expenses, were approximately $299.8 million, which the Company contributed to the Operating Partnership in exchange for 9,200,000 common units. We used a portion of the net proceeds from the offering to fund acquisitions, repay borrowings on the Credit Facility, and for general corporate purposes.

Common Units Outstanding

The Company owned a 96.8%, and 96.2% common general partnership interest in the Operating Partnership as of September 30, 2010 and both December 31, 2009 and September 30, 2009, respectively. The remaining 3.2%, and 3.8% common limited partnership interest as of September 30, 2010, and both December 31, 2009 and September 30, 2009, respectively, was owned in the form of common limited partnership units by certain of our executive officers and directors and also by non-affiliate investors. There were 1,723,131 common limited partnership units outstanding as of both September 30, 2010 and December 31, 2009.

The common units owned by the common limited partners may be redeemed by common limited partners 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 common limited partnership 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 balance sheet date. The aggregate value upon redemption of the then-outstanding noncontrolling common units was $57.2 million and $53.6 million as of September 30, 2010 and December 31, 2009, 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. Share-Based Compensation

Stockholder Approved Equity Compensation Plans

At September 30, 2010, we had one share-based incentive compensation plan, the Kilroy Realty 2006 Incentive Award Plan as amended (the “2006 Plan”). In May 2010, the Company’s stockholders approved the fourth amendment to the 2006 Plan. The amendment increased the number of shares of common stock authorized under the 2006 Plan by 2,990,000 shares such that the total aggregate number of shares available for issuance pursuant to the 2006 Plan is 6,120,000. It also made certain changes regarding how awards are counted prospectively against the number of shares available for issuance under the 2006 Plan. As of September 30, 2010, 4,397,197 shares were available for grant under the 2006 Plan. The number of shares that remains available for grant is calculated using the weighted share counting provisions set forth in the 2006 Plan, which are based on the type of awards that are granted. The maximum number of shares available for grant subject to full value awards (which generally include equity awards other than options and stock appreciation rights) was 1,505,889 shares as of September 30, 2010.

Summary of Nonvested Shares

A summary of the status of the Company’s nonvested shares as of January 1, 2010 and changes during the nine months ended September 30, 2010 is presented below:


				Weighted-
				Average
				Grant Date
Nonvested Shares	Shares			Fair Value
Nonvested at January 1, 2010		88,473		$	59.05
Granted		3,239			30.88
Vested		(16,358	)		46.63

Nonvested as of September 30, 2010		75,354		$	60.54

During the nine months ended September 30, 2010 and 2009, we issued 3,239 and 4,958 nonvested shares, respectively. The weighted-average grant-date fair value per share for nonvested shares granted during the nine months ended September 30, 2010 and 2009 was $30.88 and $20.17, respectively. In addition, during the nine months ended September 30, 2009, we issued 51,040 shares of common stock under a share-based compensation program that were fully vested upon issuance. The grant date fair value per share of this award was $26.94.

The total fair value of shares that vested during the nine months ended September 30, 2010 and 2009 was $0.5 million and $0.3 million, respectively, which was calculated based on the quoted closing share price of the Company’s common stock on the NYSE on the applicable date of vesting.

Summary of Restricted Stock Units

The summary of our restricted stock units (“RSUs”) activity from January 1, 2010 through September 30, 2010 was as follows:


	Nonvested RSUs
				Weighted-Average
				Grant Date Fair
	Amount			Value		Vested RSUs			Total RSUs
Outstanding at January 1, 2010		269,294		$	26.81		362,037			631,331

Outstanding as of September 30, 2010		405,336		$	28.24		301,177			706,513


(1)		On July 1, 2010, certain vested RSUs were settled in shares of the Company’s common stock given that this date was six months plus one day subsequent to one individual’s separation from service from the Company. For individuals without an elected distribution date greater than six months beyond separation from service, RSUs are automatically settled in common shares six months plus one day subsequent to separation from service. Of the total 97,593 RSUs held by this individual, 53,451 were settled for shares of the Company’s common stock and 44,142 RSUs were canceled to cover the statutory minimum tax withholding.
(2)		RSUs issued as dividend equivalents are vested upon issuance.
(3)		We accept the return of RSUs, at the current quoted market price of the Company’s common stock, to satisfy minimum statutory tax-withholding requirements related to either RSUs that have vested or RSU dividend equivalents in accordance with the terms of the 2006 Plan.

During the nine months ended September 30, 2010 and 2009, we issued 159,606 and 589,805 nonvested RSUs, respectively. The weighted-average grant-date fair value per share for nonvested RSUs granted during the nine months ended September 30, 2010 and 2009 was $30.24 and $26.71, respectively.

The total fair value of the RSUs that vested during the nine months ended September 30, 2010 and 2009, excluding the vested RSUs issued as dividend equivalents, was $0.7 million and $0.1 million, respectively, which was calculated based on the quoted closing share price of the Company’s common stock on the NYSE on the day of vesting.

Compensation Cost Recorded During the Period

The total compensation cost for all share-based compensation programs was $2.2 million and $2.6 million for the three months ended September 30, 2010 and 2009, respectively, and $6.4 million and $8.7 million for the nine months ended September 30, 2010 and 2009, respectively. Of the total share-based compensation cost, $0.3 million was capitalized as part of real estate assets for both the three months ended September 30, 2010 and 2009 and $1.1 million and $0.8 million was capitalized as part of real estate assets for the nine months ended September 30, 2010 and 2009, respectively. As of September 30, 2010, there was approximately $6.5 million of total unrecognized compensation cost related to nonvested incentive awards granted under share-based compensation arrangements that is expected to be recognized over a weighted-average period of 1.4 years. The remaining compensation cost related to these nonvested incentive awards had been recognized in periods prior to September 30, 2010.

The $6.5 million of unrecognized compensation cost does not reflect the potential future compensation cost for the approved executive officer share-based compensation programs under which share-based awards have not yet been granted as of September 30, 2010. These programs have a performance period that precedes the grant date. The Company recorded approximately $1.4 million related to these programs for the nine months ended September 30, 2010, which is included in the total $6.4 million compensation cost discussed above.

11. Fair Value of Financial Instruments

12. Future Minimum Rent

We have operating leases with tenants that expire at various dates through 2027 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, 2010 for future periods is summarized as follows:

13. Commitments and Contingencies

In the third quarter of 2010, we settled outstanding litigation related to certain premises at one of our properties that had been abandoned by its former occupants. In connection with this legal settlement, we received a $3.6 million cash payment. As a result, during the quarter ended September 30, 2010, we reversed $0.6 million of allowance for bad debts which was previously recorded in prior periods for receivables related to the lease at this property.

14. Segment Disclosure

Our reportable segments consist of the two types of commercial real estate properties for which our chief operating decision-makers internally evaluate operating performance and financial results: Office Properties and Industrial Properties. We also have certain corporate level activities including legal administration, accounting, finance, and management information systems, 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 the segment activity to consolidated net income for the three and nine months ended September 30, 2010 and 2009, and the consolidated financial position as of September 30, 2010 and December 31, 2009:

On October 13, 2010, we completed the sale of one industrial building to an unrelated third party for approximately $5.0 million.

In October 2010, we entered into two separate purchase and sale agreements with two separate unrelated third parties to acquire two office properties encompassing an aggregate of 588,000 square feet of space for approximately $238 million. Both acquisitions are currently anticipated to close in the fourth quarter of 2010, subject to customary closing conditions.

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 Kilroy Realty Corporation and Kilroy Realty, L.P. because the results are essentially identical for both 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 timing and costs, and investment amounts. Although the information is based on our current expectations, actual results could vary from expectations stated in this report. Numerous factors could affect our actual results, some of which are beyond our control. These include the breadth and duration of the current slowness in 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, competitive market conditions, interest rate levels, volatility in our stock price, and capital market conditions. You are cautioned not to place undue reliance on this information, which speaks only as of the date this report was filed. 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 annual report on Form 10-K for the fiscal year ended December 31, 2009, Item 1A: Risk Factors in the Operating Partnership’s General Form for Registration for Securities on Form 10 filed with the SEC on August 18, 2010, and the discussion under the captions “-Factors That May Influence Future Results of Operations” and “-Liquidity and Capital Resources for the Company” and “-Liquidity and Capital Resources for the Operating Partnership” below. In light of these risks, uncertainties, and assumptions, the forward-looking events discussed in this report might not occur.

Overview and Background

We own, operate, develop, redevelop, and acquire office and industrial real estate located in California. We qualify and operate as a self-administered REIT. 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 96.8%, and 96.2% general partnership interest in the Operating Partnership as of September 30, 2010 and both December 31, 2009 and September 30, 2009, 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 leases for the land that expire in 2084.

Factors That May Influence Future Results of Operations

Acquisitions. As a key component of our growth strategy, we continually evaluate selected property acquisition opportunities. We consider potential acquisitions on an ongoing basis and may have one or more potential acquisitions under consideration at any point in time, which may be at varying stages of the negotiation and due diligence review process. We generally finance our acquisitions through debt and equity offerings and borrowings on our unsecured line of credit (the “ New Credit Facility”).

During the nine months ended September 30, 2010, we completed five acquisitions of seven buildings for approximately $429.4 million (see Note 2 to our consolidated financial statements included in this report for additional information). In addition, subsequent to September 30, 2010 we entered into separate agreements to acquire two office properties located in San Francisco, California and the Bellevue area of greater Seattle, Washington encompassing an aggregate 588,000 square feet of space.

	•		In San Francisco, we are currently a party to a purchase and sale agreement with an unrelated third party to acquire an approximate 466,000 square-foot office property located in San Francisco’s South Financial District for approximately $191.5 million.

	•		In the greater Seattle area, we are currently a party to a purchase and sale agreement with an unrelated third party to acquire an approximate 122,000 square-foot office property for approximately $46.0 million.

Both acquisitions are expected close in the fourth quarter, subject to customary closing conditions. We cannot provide assurance that any of the pending acquisitions described above will be consummated at the prices, on the terms or by the dates currently contemplated, or at all, or that any potential acquisitions 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.

Real Estate Asset Valuation. General economic conditions and the resulting impact on market conditions such as the downturn in tenants’ businesses, declining demand for office or industrial properties, or decreases in market rental rates, or the market values of real estate assets generally, may adversely affect the value of our assets, including the value of our properties and related tenant improvements and the value of our undeveloped land. Although our strategy is to hold our properties and our undeveloped land for long-term use, if our strategy and/or market conditions change or we decide to dispose of an asset, we may be required to recognize an impairment loss to reduce the property or undeveloped land to the lower of the carrying amount or fair value, and such a loss could potentially be material and could adversely affect our results of operations. Likewise, if as a result of an early lease termination we were required to remove and write off material amounts of tenant improvements that were not reusable to another tenant, our results of operations could be adversely affected.

We evaluate our real estate assets for potential impairment, on a property-by-property basis, whenever events or changes in circumstances with respect to a specific market, submarket or property indicate that the carrying amount of a given asset may not be recoverable.

In recent periods, circumstances occurred that indicated that an analysis for potential impairment of certain of our properties was necessary. As a result, for each property where such an indicator occurred and/or for properties within a given submarket where such an indicator occurred, we completed an impairment evaluation. After completing this process, we determined that for each of the properties evaluated, undiscounted cash flows over the holding period were in excess of carrying value and, therefore, we did not record any impairment losses for the nine months ended September 30, 2010 or 2009 or the years ended December 31, 2009, 2008, and 2007.

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, 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, 2010.

(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 shown, including first and second generation space, net of month-to-month leases. Excludes leasing on new construction.
(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 we acquired the property.
(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 we acquired the property.
(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 208,700 and 542,200 rentable square feet for the three and nine months ended September 30, 2010, 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 in order to provide a meaningful market comparison.

In general, we have been experiencing decreases in rental rates in many of our submarkets over the last several quarters due to continuing slow economic growth and other related factors. During the third quarter of 2010, we executed 32 leases for an aggregate of 0.4 million 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 9.5% decrease in cash rents and a 7.6% decrease in GAAP rents, excluding leases for which the space was vacant longer than one year. As of September 30, 2010, we believe that the weighted average cash rental rates for our overall portfolio, including recently acquired properties, are approximately 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. As previously discussed, our rental rates and occupancy are impacted by general economic conditions, including the pace of regional economic growth and access to capital. Therefore, given the impact of the current economy on our submarkets, 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 2010 and the next five years, which is in addition to the 1.8 million rentable square feet, or 13.6%, of vacant space in our stabilized portfolio at September 30, 2010. Our ability to re-lease available space depends upon the market conditions in the specific regions in which our properties are located as well as market conditions generally.

(1)		The information presented reflects leasing activity through September 30, 2010. 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, 2010.
(2)		Reflects annualized contractual base rental revenue calculated on a straight-line basis.

Leases representing approximately 2.4% and 8.3% of the occupied square footage of our stabilized portfolio are scheduled to expire during the remainder of 2010 and in 2011, respectively. The leases scheduled to expire during the remainder of 2010 and in 2011 represent approximately 0.9 million rentable square feet of office space, or 7.1% of our total annualized base rental revenue, and 0.4 million rentable square feet of industrial space, or 1.2% of our total annualized base rental revenue. As of September 30, 2010, we believe that the weighted average cash rental rates for leases scheduled to expire during the remainder of 2010 are up to approximately 10% above the current average market rental rates, and leases scheduled to expire during 2011 are approximately 15% to 20% above 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.

Sublease Activity. Of our leased space as of September 30, 2010, approximately 255,100 rentable square feet, or 1.9% of the square footage in our stabilized portfolio, was available for sublease compared to 297,100 rentable square feet, or 2.4% of the square footage in our stabilized portfolio, as of December 31, 2009. Of the 1.9% of available sublease space in our stabilized portfolio as of September 30, 2010, approximately 1.5% was vacant space, and the remaining 0.4% was occupied. Approximately 70.8%, 24.4%, and 4.8% of the available sublease space as of September 30, 2010 is located in the San Diego, Los Angeles, and Orange County regions, respectively. Of the approximately 255,100 rentable square feet available for sublease as of September 30, 2010, approximately 12,300 rentable square feet representing one lease is scheduled to expire in 2010, and approximately 43,300 rentable square feet representing two leases are scheduled to expire in 2011.

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 result of which is a higher economic return on the property. While we have currently delayed the timing and reduced the scope of our development program as a result of the present economic conditions in our submarkets, we continue to evaluate development opportunities throughout California and specifically in our core markets. In addition, during the quarter ended September 30, 2010 we commenced the redevelopment of one our buildings in the El Segundo submarket of Los Angeles County which encompasses approximately 300,000 rentable square feet. We will be upgrading and modernizing the building since it was previously occupied by the Boeing Company and its predecessors for more than 25 years. The project has a total estimated investment of approximately $50 million and is expected to be completed in the third quarter of 2012 (see additional information under the caption “-Liquidity and Capital Resources of the Operating Partnership — Liquidity Uses — Redevelopment and Acquisition Opportunities”).

Over the next two years, we plan to continue to evaluate redevelopment opportunities for other certain properties, which have been occupied by long-term tenants and require significant capital expenditures to upgrade and modernize the buildings. We also plan to continue to focus on enhancing

the entitlements for our existing development land pipeline, performing additional activities to prepare for the time when development will again be economically attractive.

Incentive Compensation. Our Executive Compensation Committee determines compensation, including equity and cash incentive programs, for our executive officers. The programs approved by the Executive Compensation Committee have historically provided for equity and cash compensation to be earned by our executive officers based on the attainment of certain performance measures, including financial, operating, and development targets.

In the first quarter of 2010, our Executive Compensation Committee approved the 2010 Annual Bonus Program for executive management that will allow executive management to receive bonus compensation for achieving certain specified corporate performance measures for the year ending December 31, 2010. As a result of the structure of this program and other performance-based and market-based programs that the Executive Compensation Committee may adopt in the future, accrued incentive compensation and compensation expense for such programs will be affected by our operating and development performance, financial results, the performance of the trading price of our common stock, and market conditions. Consequently, we cannot predict the amounts that will be recorded in future periods related to these compensation programs.

Share-Based Compensation. As of September 30, 2010, there was $6.5 million of total unrecognized compensation cost related to outstanding nonvested shares and nonvested restricted stock units issued under share-based compensation arrangements. That cost is expected to be recognized over a weighted-average period of 1.4 years. The $6.5 million of unrecognized compensation cost does not reflect the potential future compensation cost for the 2010 Annual Bonus Program or the leasing component of the 2007 Development Performance Plan (the “DPP”) since share-based awards have not been granted under these programs as of September 30, 2010. See Note 10 to our consolidated financial statements included with this report for additional information regarding our share-based incentive compensation plan.

As of September 30, 2010, we were still in the performance period for the leasing component of the DPP. The incentive award that may be earned under the leasing component of the DPP is based on whether certain future leasing targets are achieved by the fourth quarter of 2010 for development and redevelopment properties on which we commenced construction during 2007. If the performance measures are not ultimately achieved, we will reverse the cumulative compensation expense recorded to date for this program in the fourth quarter of 2010, which as of September 30, 2010 was $1.0 million.

Current Regional Information

Real estate fundamentals may continue to be challenging in many of our regional submarkets. However, since December 31, 2009, occupancy rates have increased across our portfolio, and we have generally seen a modest decrease in vacancy rates across many of our regional submarkets as well as a stabilization in rental rates and lease concession packages. See additional information regarding rental rates under the captions “-Leasing Activity and Rental Rates” and “-Scheduled Lease Expirations.”

Los Angeles and Ventura Counties. Our Los Angeles and Ventura Counties stabilized office portfolio of 3.1 million rentable square feet was 89.6% occupied with approximately 319,500 vacant rentable square feet as of September 30, 2010 compared to 88.8% occupied with approximately 376,400 vacant rentable square feet as of December 31, 2009.

As of September 30, 2010, an aggregate of approximately 163,700 and 460,000 rentable square feet are scheduled to expire in this region during the remainder of 2010 and 2011, respectively. The aggregate rentable square feet scheduled to expire in this region during the remainder of 2010 and 2011 represents approximately 21.7% of the total occupied rentable square feet in this region and 4.6% of our annualized base rental revenues for our total stabilized portfolio.

San Diego. Our San Diego stabilized office portfolio of 5.4 million rentable square feet was 82.2% occupied with approximately 954,700 vacant rentable square feet as of September 30, 2010 compared to 76.8% occupied with approximately 1.2 million vacant rentable square feet as of December 31, 2009. As of the date of this filing, we have leased approximately 269,000 rentable square feet in this region that was vacant at September 30, 2010. The new leases are scheduled to commence at various dates during the remainder of 2010 and the first quarter of 2011. During the nine months ended September 30, 2010, we acquired four San Diego office buildings encompassing approximately 279,400 rentable square feet. These four buildings were 79.3% occupied as of September 30, 2010 (see Note 2 to our consolidated financial statements included in this report for additional information).

As of September 30, 2010, leases representing an aggregate of approximately 22,300 and 152,100 rentable square feet are scheduled to expire during the remainder of 2010 and 2011, respectively, in this region. The aggregate rentable square feet scheduled to expire in this region during the remainder of 2010 and 2011 represents approximately 4.0% of the total occupied rentable square feet in this region and 1.9% of our annualized base rental revenues for our total stabilized portfolio.

Orange County. As of September 30, 2010, our Orange County stabilized industrial portfolio of approximately 3.5 million rentable square feet was 90.0% occupied with approximately 344,900 vacant rentable square feet compared to 87.6% occupied with approximately 429,900 vacant rentable square feet as of December 31, 2009. The increase in Orange County stabilized industrial portfolio occupancy is primarily attributable to a lease encompassing approximately 153,300 rentable square feet that commenced, partially offset by a lease encompassing approximately 74,300 rentable square feet that expired during the first quarter of 2010. Approximately

144,000 rentable square feet of the 344,900 rentable square feet that was vacant as of September 30, 2010 has been re-leased to a new tenant. The new lease is expected to commence during the fourth quarter of 2010.

Our Orange County stabilized office portfolio of approximately 647,400 rentable square feet was 78.7% occupied with approximately 137,700 vacant rentable square feet as of September 30, 2010 compared to 49.8% occupied with approximately 139,100 vacant rentable square feet as of December 31, 2009. During the second quarter of 2010, we acquired two Orange County office buildings encompassing approximately 370,100 rentable square feet. These two buildings were 97.8% occupied as of September 30, 2010 (see Note 2 to our consolidated financial statements included in this report for additional information).

As of September 30, 2010, leases representing an aggregate of approximately 88,500 and 318,900 rentable square feet are scheduled to expire during the remainder of 2010 and 2011, respectively, in this region. The aggregate rentable square feet scheduled to expire during the remainder of 2010 and 2011 represents approximately 11.2% of the total occupied rentable square feet in this region and 1.6% of the annualized base rental revenues for our total stabilized portfolio. Of the 407,400 rentable square feet scheduled to expire during the remainder of 2010 and 2011, approximately 377,300 rentable square feet is industrial space. Within the overall Orange County market, total vacancy for industrial space is currently 10.0%. Over the last year, the Orange County industrial market has experienced a significant decrease in rental rates. As of September 30, 2010, we believe that the weighted average cash rental rates for our Orange County industrial portfolio are approximately 15.0% above the current average market rental rates, although individual properties may be leased either above, below, or at the current average market rental rates.

San Francisco. During the quarter ended June 30, 2010, we acquired one office building in San Francisco encompassing approximately 734,000 rentable square feet. The building was 89.4% occupied as of September 30, 2010 (see Note 2 to our consolidated financial statements included in this report for additional information). As of September 30, 2010, no leases are scheduled to expire during the remainder of 2010 and leases representing an aggregate of approximately 22,600 rentable square feet are scheduled to expire during 2011 in this region. The aggregate rentable square feet scheduled to expire in this region during the remainder of 2010 and 2011 represents approximately 3.5% of the total occupied rentable square feet in this region and less than 0.3% of our annualized base rental revenues for our total stabilized portfolio. Total vacancy in the San Francisco South Financial District office market is currently 12.6%.

Results of Operations

Management internally evaluates the operating performance and financial results of our portfolio based on Net Operating Income for the following 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). The Net Operating Income segment information presented within this Management’s Discussion and Analysis of Financial Condition and Results of Operations consists of the same Net Operating Income segment information disclosed in Note 14 to our consolidated financial statements.

(1)		Office Properties owned and stabilized as of January 1, 2009 and still owned and stabilized as of September 30, 2010.

Rental Income

Rental Income from Office Properties increased $11.8 million, or 21.6%, for the three months ended September 30, 2010 compared to the three months ended September 30, 2009 primarily due to:

	•		An increase of $11.1 million generated by seven office buildings we acquired during 2010 (the “Office Acquisition Properties”);

	•		An increase of $1.6 million primarily due to an increase in average occupancy for the Office Properties owned and stabilized as of January 1, 2009 and still owned and stabilized as of September 30, 2010 (the “Core Office Portfolio”). Average occupancy increased 2.1%, from 82.5% for the three months ended September 30, 2009, to 84.6% for the three months ended September 30, 2010; and

	•		An offsetting decrease of $0.9 million generated by one office building that was moved from the stabilized portfolio to the redevelopment portfolio during the third quarter of 2010 (the “Office Redevelopment Property”).

Tenant Reimbursements

Tenant reimbursements from Office Properties decreased $0.6 million, or 9.4%, for the three months ended September 30, 2010 compared to the three months ended September 30, 2009 primarily due to:

	•		A decrease of $0.4 million generated by the Core Office Portfolio primarily due to the renewal of several leases, which resulted in the reset of the base year expense level;

	•		A decrease of $0.4 million generated by the Office Redevelopment Property; and

	•		An offsetting increase of $0.2 million generated by Office Acquisition Properties.

Property Expenses

Property expenses from Office Properties increased $3.2 million, or 27.4%, for the three months ended September 30, 2010 compared to the three months ended September 30, 2009 primarily due to:

	•		An increase of $2.8 million generated by the Office Acquisition Properties; and

	•		An increase of $0.5 million generated by the Core Office Portfolio primarily due to:

	•		An increase of $0.8 million attributable to an increase in certain recurring operating costs such as utilities, property management expenses, janitorial and other service-related costs partially due to increase in average occupancy;

	•		An increase of $0.4 million attributable to an increase in nonreimbursable legal fees and consulting costs; and

	•		An offsetting $0.6 million included in the 2009 results related to nonrecurring repairs.

Real Estate Taxes

Real estate taxes from Office Properties increased $1.6 million, or 31.4%, for the three months ended September 30, 2010 compared to the three months ended September 30, 2009 primarily due to an increase of $1.2 million in real estate taxes attributable to the Office Acquisition Properties.

Provision for Bad Debts

The provision for bad debts from Office Properties for the three months ended September 30, 2010 included a reversal of $0.6 million of a previously recorded provision for bad debts. During the third quarter of 2010, we settled outstanding litigation related to certain premises at one of our properties that had been abandoned by its former occupants (see Note 13 to our consolidated financial statements included in this report for additional information).

Net Operating Income

Net Operating Income from Office Properties increased $7.6 million, or 17.4%, for the three months ended September 30, 2010 compared to the three months ended September 30, 2009 primarily due to:

(1)		Industrial Properties owned and stabilized as of January 1, 2009 which are still owned and stabilized as of September 30, 2010.

Rental Income

Rental income from Industrial Properties decreased $0.5 million, or 7.2%, for the three months ended September 30, 2010 compared to the three months ended September 30, 2009 primarily due a decrease in GAAP rents of approximately 20% for leases that commenced at the Core Industrial Portfolio Properties in the three months ended September 30, 2010 (see additional information under the caption “-Factors That May Influence Results of Operations”).

Other Property Income

Other property income from Industrial Properties increased $0.5 million for the three months ended September 30, 2010 compared to the three months ended September 30, 2009. During the third quarter of 2010 we recognized $0.6 million of a $1.0 million surrender fee that is being amortized over the remaining lease term for one tenant that will be vacating one of our Industrial Properties in Orange County during the fourth quarter of 2010.

Net Operating Income

Net Operating Income from Industrial Properties increased $0.1 million, or 2.3%, for the three months ended September 30, 2010 compared to the three months ended September 30, 2009 primarily due to the amortization of a surrender fee from a tenant that will be vacating one of our Industrial Properties in Orange County during the fourth quarter of 2010.

Other Expenses and Income

General and Administrative Expense

General and administrative expenses decreased $0.4 million, or 5.1%, for the three months ended September 30, 2010 compared to the three months ended September 30, 2009 primarily due to a decrease in incentive compensation expense.

Acquisition-related Expenses

During the three months ended September 30, 2010, we incurred third-party acquisition costs in connection with acquisitions completed in 2010 and other potential acquisitions. See additional information under the caption “-Factors That May Influence Future Results of Operations-Acquisitions.” In accordance with accounting provisions, all acquisition costs related to operating properties are expensed as incurred. We anticipate that we could incur additional third-party acquisition costs throughout 2010 as we pursue other potential acquisition opportunities.

Depreciation and Amortization

Depreciation and amortization increased by $8.1 million, or 36.8% for the three months ended September 30, 2010 compared to the three months ended September 30, 2009 primarily due to:

	•		Approximately $3.0 million related to acquisitions; and

	•		Approximately $3.2 million related to the change in the estimated useful life of an industrial property that we are in the process of repositioning (see Note 1 to our consolidated financial statements included in this report for additional information).

Interest Expense

The following table sets forth our gross interest expense, including debt discounts and loan cost amortization, net of capitalized interest for the three months ended September 30, 2010 and 2009:


							Dollar			Percentage
	2010			2009			Change			Change
	($ in thousands)
Gross interest expense	$	18,543		$	13,540		$	5,003			36.9	%

Interest expense	$	15,853		$	10,926		$	4,927			45.1	%

Gross interest expense, before the effect of capitalized interest, increased $5.0 million, or 36.9%, for the three months ended September 30, 2010 compared to the three months ended September 30, 2009 due to an increase in both our average debt balance and our weighted-average effective interest rate from approximately 5.5% during the three months ended September 30, 2009 to approximately 6.4% during the three months ended September 30, 2010.

(1)		Office Properties owned and stabilized as of January 1, 2009 and still owned and stabilized as of September 30, 2010.

Rental Income

Rental income from Office Properties increased $13.2 million, or 8.0%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 primarily due to:

	•		An increase of $14.5 million generated by the Office Acquisition Properties; and

	•		An offsetting decrease of $0.9 million attributable to the Office Redevelopment Property.

Tenant Reimbursements

Tenant reimbursements from Office Properties decreased $3.1 million, or 16.3%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 primarily due to a decrease of $2.6 million generated by the Core Office Portfolio. During the nine months ended September 30, 2010, there was a decrease attributable to the renewal of several leases which resulted in the reset of the base year expense level for these leases.

Other Property Income

Other property income from Office Properties decreased $0.6 million for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009. Included in the results for 2009 is a $1.3 million net lease termination fee related to a settlement with a former tenant. Included in the results for 2010 is approximately $0.7 million in lease termination and restoration fees from three tenants that have vacated three of our Office Properties in Los Angeles County.

Property expenses from Office Properties increased $4.5 million, or 12.8%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 primarily due to:

	•		An increase of $3.7 million generated by the Office Acquisition Properties; and

	•		An increase of $0.9 million generated by the Core Office Portfolio primarily due to:

	•		An increase of $1.0 million attributable to an increase in certain recurring operating costs such as property management expenses, repairs and maintenance, janitorial and other service-related costs;

	•		An increase of $1.3 million due to nonreimbursable legal fees and consulting costs; and

	•		An offsetting decrease of $0.9 million related to nonrecurring repairs in 2009.

Real Estate Taxes

Real estate taxes from Office Properties increased $1.9 million, or 11.7%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 primarily due to the Office Acquisition Properties.

Provision for Bad Debts

The provision for bad debts from Office Properties for the nine months ended September 30, 2010 included a reversal of $0.6 million of a previously recorded provision for bad debts. During the third quarter of 2010, we settled outstanding litigation related to certain premises at one of our properties that had been abandoned by its former occupants (see Note 13 to our consolidated financial statements included in this report for additional information).

Ground Leases

Ground lease expense from Office Properties decreased $0.6 million, or 47.2%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 primarily due to a ground rent expense adjustment for our Kilroy Airport Center, Long Beach project. During the first quarter of 2010, we were successful in negotiating a lower rental rate under the terms of the ground lease retroactive to January 1, 2006.

Net Operating Income

Net Operating Income from Office Properties increased $4.6 million, or 3.4%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 primarily due to:

	•		An increase of $9.6 million attributable to the Office Acquisition Properties;

	•		An offsetting decrease of $3.6 million attributable to the Core Office Portfolio primarily due to:

	•		A decrease of $2.6 million due to a decrease in tenant reimbursements primarily attributable to the renewal of several leases which resulted in the reset of the base year expense level for these leases; and

	•		A decrease of $1.3 million net lease termination fee included in the results for 2009 related to a settlement with a former tenant; and

•

An offsetting decrease of $1.1 million attributable to the Office Redevelopment Property.

(1)		Industrial Properties owned and stabilized as of January 1, 2009 which are still owned and stabilized as of September 30, 2010.

Rental Income

Rental income from Industrial Properties decreased $1.9 million, or 9.0%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 primarily due to:

	•		A 5.6% decrease in average occupancy for the Core Industrial Portfolio from 91.3% for the nine months ended September 30, 2009 to 85.7% for the nine months ended September 30, 2010; and

	•		A decrease in GAAP rents of approximately 20% for leases that commenced during the nine months ended September 30, 2010 (please see additional information under the caption “-Factors That May Influence Results of Operations”).

Tenant Reimbursements

Tenant reimbursements from Industrial Properties decreased $0.4 million, or 13.3%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 due to a decrease in the Core Industrial Portfolio’s average occupancy, as discussed above under the caption “-Rental Income.”

Other Property Income

Other property income from Industrial Properties decreased $0.2 million, or 18.4%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009. Included in the results for 2009 is a $1.1 million restoration fee from a tenant that vacated one of our Industrial Properties in Orange County. Included in the results for 2010 is the recognition of $0.8 million of a $1.0 million surrender fee that is being amortized over the remaining term of a lease with a tenant that will be vacating one of our Industrial Properties in Orange County during the fourth quarter of 2010.

Property Expenses

Property expenses from Industrial Properties increased $0.3 million, or 12.6%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 primarily due to an increase in nonreimbursable legal fees mainly due to tenant defaults that occurred during 2009.

Provision for Bad Debts

Provision for bad debts from Industrial Properties decreased $0.4 million, or 109.2%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 due to changes in our estimates of collectability of receivables from certain watchlist tenants.

Net Operating Income

Net Operating Income from Industrial Properties decreased $2.4 million, or 12.4%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 primarily due to a decrease in average occupancy year over year at the Core Industrial Portfolio and a decrease of approximately 20% for leases that commenced during the nine months ended September 30, 2010.

Other Expenses and Income

General and Administrative Expense

General and administrative expenses decreased $0.9 million, or 4.2%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 primarily due to a decrease in incentive compensation expense.

Acquisition-related Expenses

During the nine months ended September 30, 2010, we incurred third-party acquisition costs in connection with acquisitions completed in 2010 and other potential acquisitions. See additional information under the caption “-Factors That May Influence Future Results of Operations-Acquisitions.” We anticipate that we could incur additional third-party acquisition costs throughout 2010 as we pursue other potential acquisition opportunities.

Depreciation and Amortization

Depreciation and amortization increased by $8.1 million, or 12.2% for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 primarily due to:

	•		Approximately $3.7 million related to acquisitions; and

	•		Approximately $4.3 million related to the change in the estimated useful life of an industrial property that we are in the process of repositioning (see Note 1 to our consolidated financial statements included in this report for additional information).

Interest Expense

The following table sets forth our gross interest expense, including debt discounts and loan cost amortization, net of capitalized interest for the nine months ended September 30, 2010 and 2009:


							Dollar			Percentage
	2010			2009			Change			Change
	($ in thousands)
Gross interest expense	$	48,980		$	41,992		$	6,988			16.6	%
Capitalized interest		(8,083	)		(6,951	)		(1,132	)		16.3	%

Interest expense	$	40,897		$	35,041		$	5,856			16.7	%

Gross interest expense, before the effect of capitalized interest, increased $7.0 million, or 16.6%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 primarily due to a change in our debt composition which increased our weighted-average effective interest rate from approximately 5.1% during the nine months ended September 30, 2009 to approximately 6.2% during the nine months ended September 30, 2010.

Capitalized interest increased $1.1 million, or 16.3%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 primarily due to an increase in our weighted-average effective interest rate, which caused a corresponding increase in the capitalization rate applied to our development and redevelopment asset balances qualifying for interest capitalization. During both the nine months ended September 30, 2010 and 2009, we did not capitalize interest on five of our seven development pipeline properties with an aggregate cost basis of approximately $82 million as of September 30, 2010. In addition, in September 2010, we ceased interest capitalization on another one of our development pipeline properties with an aggregate cost basis of approximately $77.3 million as of September 30, 2010. We have suspended substantially all development activities related to these projects as a result of economic conditions in our submarkets and we determined these projects did not qualify for interest capitalization under GAAP.

Interest Income and Other Net Investment Gains

Total interest income and other net investment gains income is lower by $0.4 million, or 34.5%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 due to:

	•		A decrease of $0.2 million in gains in the fair market value of marketable securities held in connection with our deferred compensation plan during the nine months ended September 30, 2010 as compared to the nine months ended September 30, 2009: and

	•		A decrease of $0.2 million in interest income during the nine months ended September 30, 2010 as compared to the nine months ended September 30, 2009 due to the repayment of the note receivable in July 2010 (see Note 4 to our consolidated financial statements included in this report for additional information).

(Loss) Gain on Early Extinguishment of Debt

During the nine months ended September 30, 2010, we recorded a loss on early extinguishment of debt of approximately $4.6 million due to the repurchase of 3.25% Exchangeable Notes with an aggregate stated principal amount of $150.0 million (see Note 6 to our consolidated financial statements included in this report for additional information). During the nine months ended September 30, 2009, we recorded a gain on early extinguishment of debt of approximately $3.1 million due to the repurchase of 3.25% Exchangeable Notes with an aggregate stated principal amount of $40.0 million.

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. For further discussion of the liquidity and capital resources of the Company on a consolidated basis see the section entitled “Liquidity and Capital Resources of the Operating Partnership” below.

The Company’s business is operated primarily through the Operating Partnership. The Company issues public equity from time to time, but does not otherwise generate any capital itself or conduct any business itself, other than incurring certain expenses in operating as a public company which are fully reimbursed by the Operating Partnership. The Company itself does not hold any indebtedness, and its only material asset is its ownership of partnership interests of the Operating Partnership. The Company’s principal funding requirement is the payment of dividends on its common and preferred shares. The Company’s principal source of funding for its dividend payments is distributions it receives from the Operating Partnership.

As of September 30, 2010, the Company owned a 96.8%, general partnership interest in the Operating Partnership excluding preferred units. The remaining 3.2% common limited partnership interest as of September 30, 2010 was owned by non-affiliate investors and certain of our executive officers and directors. Through its ownership as the sole general partner of the Operating Partnership, the Company has the full, exclusive and complete responsibility for the Operating Partnership’s day-to-day management and control. The Company causes the Operating Partnership to distribute all, or such portion as the Company may in its discretion determine, of its available cash in the manner provided in the Operating Partnership’s partnership agreement. Distributions from the Operating Partnership are the Company’s primary source of capital.

The Company is a well-known seasoned issuer with an effective shelf registration statement which was amended in September 2010 that allows the Company to register unspecified various classes of equity securities and the Operating Partnership to register unspecified and various classes of debt securities. As circumstances warrant, the Company may issue equity from time to time on an opportunistic basis, dependent 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 preferred or common partnership units of the Operating Partnership. The Operating Partnership may use the proceeds to repay debt, including borrowings under its line of credit, develop new or existing properties, to make acquisitions of properties, portfolios of properties, or for general corporate purposes.

The liquidity of the Company is dependent on the Operating Partnership’s ability to make sufficient distributions to the Company. The Company also guarantees some of the Operating Partnership’s debt, as discussed further in Note 5 to the consolidated financial statements. If the Operating Partnership fails to fulfill certain of its debt requirements, which trigger Company guarantee obligations, then the Company will be required to fulfill its cash payment commitments under such guarantees. However, the Company’s only significant asset is its investment in the Operating Partnership.

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 shareholders. Cash flows from operating activities generated by the Operating Partnership for the nine months ended September 30, 2010 were sufficient to cover the Company’s payment of cash dividends to its shareholders. 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 distribution payments to the Company. The unavailability of capital could adversely affect the Operating Partnership’s ability to pay its distributions to the Company, which would in turn, adversely affect the Company’s ability to pay cash dividends to its shareholders.

For the Company to maintain its qualification as a real estate investment trust, it must pay dividends to its shareholders aggregating annually at least 90% of its REIT taxable income. While historically the Company has satisfied this distribution requirement by making cash distributions to its shareholders, it may choose to satisfy this requirement by making distributions of cash or other property, including, in limited circumstances, the Company’s own shares. As a result of this distribution requirement, the Operating Partnership cannot rely on retained earnings to fund its on-going operations to the same extent that other companies whose parent companies are not real estate investment trusts can. The Company may need to continue to raise capital in the equity markets to fund the Operating Partnership’s working capital needs, as well as potential developments at new or existing properties, acquisitions or investments in existing or newly created joint ventures.

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. Because the Company consolidates the Operating Partnership for financial reporting purposes, 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.

Dividends

On September 14, 2010, the Company’s Board of Directors declared a $0.35 cash dividend per common share payable on October 15, 2010 to each common shareholder of record on September 30, 2010, and caused a $0.35 per Operating Partnership unit cash distribution to be paid to the the common limited partnership interests not owned by the Company.

On September 14, 2010, the board of directors also declared a dividend of $0.4875 per share on the Company’s 7.80% Series E Cumulative Redeemable Preferred Stock and a dividend of $0.46875 per share on the company’s 7.50% Series F Cumulative Redeemable Preferred Stock for the period commencing on and including August 15, 2010 and ending on and including November 14, 2010.

Debt Covenants

One of the covenants contained within the New Credit Facility prohibits the Company from paying dividends in excess of 95% of funds from operations (“FFO”).

Capitalization

As of September 30, 2010, our total debt as a percentage of total market capitalization was 37.1% and our total debt and liquidation value of our preferred equity as a percentage of total market capitalization was 43.5%, which was calculated based on the closing price per share of the Company’s common stock of $33.14 on September 30, 2010 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 Operating Partnership and the Company together, as the context requires.

General

Our primary liquidity sources and uses are as follows:

Liquidity Sources

	•		Net cash flow from operations;

	•		Borrowings under the New 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;

	•		Operating and corporate expenses;

	•		Capital expenditures, tenant improvement and leasing costs;

	•		Development and redevelopment costs;

	•		Debt service and principal payments, including debt maturities;

	•		Distributions to common and preferred stockholders and unitholders; and

	•		Purchasing outstanding debt.

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 potential liquidity sources listed above. We believe our conservative leverage and staggered debt maturities provides 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.

2010 Financing Activities

During the first nine months of 2010, we completed a variety of capital raising activities which significantly extended our debt maturities and enabled us to fund five property acquisitions. This financing and acquisition activity increased our consolidated total assets by approximately 20% as compared to December 31, 2009, without increasing our total debt as a percentage of total market capitalization. The following activities occurred during the period:

	•		In September 2010, the Operating Partnership became a registered public entity allowing us additional flexibility to access the public debt markets.

	•		In August 2010, the Operating Partnership entered into a $500.0 million New Credit Facility with a term of three years plus a one year extension option. We used borrowings under the New Credit Facility to repay, and then terminate, our existing $550.0 million unsecured line of credit (the “Credit Facility”).

	•		In August 2010, the Operating Partnership used borrowings under our Credit Facility to repay a portion of our unsecured senior notes, with a principal balance of $61.0 million that was maturing.

	•		In June 2010, the Operating Partnership completed a tender offer for the repurchase of $150 million in aggregate stated principal value of the 3.25% Exchangeable Notes (see Note 6 to our consolidated financial statements included in this report for additional information).

	•		In June 2010, the Operating Partnership assumed secured debt with a principal balance of $52.0 million in conjunction with the acquisition of Mission City Corporate Center in San Diego, CA (see Notes 1, 2, and 6 to our consolidated financial statements included in this report for additional information).

	•		In May 2010, the Operating Partnership issued $250.0 million in aggregate stated principal amount of 6.625% unsecured senior notes due 2020 (see Note 6 to our consolidated financial statements included in this report for additional information).

	•		In April 2010, the Company completed an underwritten public offering of 9,200,000 shares of our common stock. The net offering proceeds, after deducting underwriting discounts and commissions and offering expenses, of approximately $299.8 million were contributed to the Operating Partnership in exchange for common units issued to the Company. (see Notes 8 and 9 to our consolidated financial statements included in this report for additional information).

	•		In April 2010, the Operating Partnership was assigned initial investment grade credit ratings by two major rating agencies, which we believe enhances our access to the capital markets by allowing the Operating Partnership to raise long-term unsecured debt financing in the bond market.

	•		In March 2010, the Operating Partnership used borrowings under our Credit Facility to repay a secured line of credit with an outstanding principal balance of $33.5 million that was scheduled to mature in April 2010.

	•		In January 2010, the Operating Partnership used the proceeds from the issuance of a $71.0 million mortgage loan to repay an outstanding mortgage loan with a principal balance of $63.2 million that was scheduled to mature in April 2010. The mortgage loan is secured by five properties, bears interest at an annual rate of 6.51%, requires monthly interest and principal payments based on a 30-year amortization period, and is scheduled to mature on February 1, 2017.

As of December 31, 2009, the fee for unused funds for the Credit Facility was at an annual rate of 0.15% to 0.20%, depending on the balance of our daily average undrawn balance. In addition, we also incurred debt origination and legal costs of approximately $5 million, which will be amortized as additional interest expense through the contractual maturity date.

As discussed above under the caption “-2010 Financing Activities”, the Operating Partnership entered into the New Credit Facility in August 2010 and used borrowings under the New Credit Facility to repay, and then terminate, the Credit Facility. The New Credit Facility includes a $200.0 million accordion option and has a term of three years plus a one year extension option. The New Credit Facility bears interest at an annual rate of LIBOR plus 2.675%.

Redevelopment and Acquisition Opportunities

During the first nine months of 2010, we spent approximately $373.6 million to acquire five properties encompassing seven buildings. We funded these acquisitions principally with the net proceeds from the issuance of the 6.625% unsecured senior notes due 2020, the net proceeds from the Company’s public offering of common stock, and borrowings under the unsecured line of credit (see Notes 2, 6 and 8 to our consolidated financial statements for more information). We continue to evaluate strategic opportunities to acquire additional properties that provide attractive yields, significant potential for growth in cash flow from operations, present growth opportunities in strategic markets, or demonstrate the potential for improved performance through strategic management. We expect that we could finance any potential material acquisitions with borrowings under our New Credit Facility or the public issuance of new debt or equity securities.

As of September 30, 2010, we had one redevelopment project under construction. This project has a total estimated investment of approximately $50 million of which we have incurred approximately $12 million as of September 30, 2010. Of the remaining $38 million yet to be incurred, we are currently contractually obligated to pay approximately $18 million over the next two years as shown in the table above. In addition, we expect we may incur up to approximately $20 million in leasing related costs, depending on leasing activity. Ultimate timing of these expenditures may fluctuate given the ultimate progress and status of the redevelopment project. We also estimate that we could spend up to to an additional $20 million on other future redevelopment and development pipeline projects during 2010 and 2011, depending on market conditions.

Factors That May Influence Future Sources of Capital and Liquidity

We continue to evaluate sources of financing for our business activities, including borrowings under the New Credit Facility, issuance of public and private unsecured debt, fixed-rate secured mortgage financing, and offerings of the Company’s common stock. However, the Operating Partnerships ability to obtain new financing or refinance existing borrowings on favorable terms could be impacted by various factors including continuing economic conditions, significant tenant defaults, a further decline in the demand for office or industrial properties, a further 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 New Credit Facility;

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

	•		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.

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 New 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. The more restrictive financial covenants and their covenant levels include:


		Actual Performance at
	Covenant Level	September 30, 2010
Unsecured Line of Credit (as defined per Credit Agreement):
Total debt to total asset value	less than 60%		31	%
Fixed charge coverage ratio	greater than 1.5x		2.7	x
Unsecured debt ratio	greater than 1.67x		2.95	x
Unencumbered asset pool debt service coverage	greater than 2.0x		5.2	x
Unencumbered debt yield	greater than 12%		19	%

Unsecured Senior Notes due 2020 (as defined per Indenture):
Total debt/total asset value	less than 60%		38	%
Interest coverage	greater than 1.5x		3.7	x
Secured debt/total asset value	less than 40%		10	%
Unencumbered asset pool value to unsecured debt	greater than 150%		302	%

The Operating Partnership was in compliance with all our debt covenants as of September 30, 2010. Our current expectation is that the Operating Partnership will continue to meet requirements of its debt covenants in both the short and long term. However, in the event of a continued economic slow down and 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.

Historical Cash Flow Summary

Our historical cash flow activity for the nine months ended September 30, 2010 as compared to the nine months ended September 30, 2009 is as follows:


	Nine Months Ended September 30,
							Dollar			Percentage
	2010			2009			Change			Change
	($ in thousands)
Net cash provided by operating activities	$	94,928		$	98,000		$	(3,072	)		(3.1	)%
Net cash used in investing activities		(434,655	)		(37,399	)		(397,256	)		(1,062.2	)%
Net cash provided by (used in) financing activities		338,157			(60,889	)		399,046			(655.4	)%

Operating Activities

Our cash flows from operations is primarily dependent on the occupancy level of our portfolio, the rental rates achieved on our leases, the collectability of rent and recoveries from our tenants and the level of operating expenses, and other general and administrative costs. Our cash flows from operations in the future will also be impacted by the operating results of any acquired and potential acquisition properties. Our net cash provided by operating activities decreased by $3.1 million, or 3.1%, for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009 primarily due to an increase in expenditures for severance costs and acquisition related costs.

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 $397.3 million for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009. This net increase was primarily comprised of the following:

	•		Approximately $373.6 million in cash paid to acquire five operating properties during 2010 (see Note 2 to our consolidated financial statements included in this report for additional information);

	•		An increase of $31.3 million in expenditures for our operating properties in 2010 primarily for tenant improvement projects and leasing commissions related to increased leasing activity at the end of 2009 and in 2010 ; and

	•		An offsetting decrease of $10.7 million in cash received for the note receivable balance paid in full in the third quarter of 2010 (see Note 4 to our consolidated financial statements included in this report for additional information).

Financing Activities

Our net cash provided by or used in financing activities is generally impacted by our debt and equity capital raising activities net of dividends and distributions paid to common and preferred stockholders and unit holders. Net cash provided by financing activities fluctuated by $399.0 million for the nine months ended September 30, 2010 compared to the nine months ended September 30, 2009. The net change in cash provided by financing activities was primarily due to the following:

	•		An increase in capital raising activities, including the Operating Partnership’s issuance of secured and unsecured debt, and the Company’s issuance of 9.2 million shares of common stock, primarily to fund our 2010 property acquisitions (see Notes 2, 6, and 8 to our consolidated financial statements included in this report for additional information);

	•		An offsetting decrease related to the repurchase of $150.0 million in aggregate stated principal of 3.25% Exchangeable Notes during 2010 (see Note 6 to our consolidated financial statements included in this report for additional information); and

	•		The impact of the 40% decrease in our cash dividend rate enacted by our Board of Directors in the second quarter of 2009. This resulted in a net $5.8 million decrease in our dividends and distributions paid to common stockholders and common unitholders during the nine months ended September 30, 2010 as compared to the nine months ended September 30, 2009.

Off-Balance Sheet Arrangements

As of September 30, 2010 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 of operations.

The following table presents our FFO for the three and nine months ended September 30, 2010 and 2009:


	Three Months Ended					Nine Months Ended

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, 2010 and December 31, 2009, we did not have any interest-rate sensitive derivative assets or liabilities.

Information about our changes in interest rate risk exposures from December 31, 2009 to September 30, 2010 is incorporated herein by reference from Item 2: Management’s Discussion and Analysis of Financial Condition and Results of Operations “-Liquidity and Capital Resources.”

Market Risk

As of September 30, 2010, approximately 17.5% of our total outstanding debt of $1.2 billion was subject to variable interest rates. The remaining 82.5% bore interest at fixed rates. 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, 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 standing, the maturity of the debt, 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 for similar nonconvertible conventional debt instruments. See Note 11 to our consolidated financial statements included in this report for additional information on the fair value of our financial instruments as of September 30, 2010 and December 31, 2009.

As of September 30, 2010, the total outstanding balance of our variable-rate debt included borrowings on our New Credit Facility of $205 million and was indexed to LIBOR plus a spread of 2.675% (weighted average interest rate was 2.98%). As of December 31, 2009, the total outstanding balance of our variable-rate debt included borrowings of $97 million on our Credit Facility, which was indexed to LIBOR plus a spread of 0.85%, and borrowings of $33.5 million on our secured line of credit, which was indexed to LIBOR plus a spread of 0.75% (weighted average interest rate was 1.1%). Assuming no changes in the outstanding balance of our existing variable-rate debt as of September 30, 2010, a 100 basis point increase in the LIBOR rate would increase our projected annual interest expense, before the effect of capitalization, by approximately $2.1 million. Comparatively, if interest rates were 100 basis points higher as of December 31, 2009, our projected annual interest expense, before the effect of capitalization, would have been $1.3 million higher.

The total carrying value of our fixed-rate debt, including our Exchangeable Notes, was approximately $944.4 million and $841.5 million as of September 30, 2010 and December 31, 2009, respectively. The total estimated fair value of our fixed-rate debt was approximately $994.8 million and $842.1 million as of September 30, 2010 and December 31, 2009, 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 $37.1 million, or 3.7%, as of September 30, 2010. 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 $20.2 million, or 2.4%, as of December 31, 2009.

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.
