1. Organization and Basis of Presentation

Organization

Kilroy Realty Corporation (the “Company”) owns, operates, develops and acquires office and industrial real estate located in Southern California. The Company qualifies and operates as a self-administered real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended.

As of March 31, 2008, the Company’s stabilized portfolio of operating properties was comprised of 86 office buildings (the “Office Properties”) and 43 industrial buildings (the “Industrial Properties”), which encompassed an aggregate of approximately 8.1 million and 3.9 million rentable square feet, respectively. As of March 31, 2008, the Office Properties were approximately 94.8% leased to 306 tenants, and the Industrial Properties were approximately 94.8% leased to 63 tenants. All of the Company’s properties are located in Southern California.

The Company’s stabilized portfolio excludes development and redevelopment properties currently under construction and “lease-up” properties (collectively, the “in-process development and redevelopment properties”). The Company defines “lease-up” properties as properties recently developed or redeveloped by the Company that have not yet reached 95% occupancy and are within one year following cessation of major construction activities. As of March 31, 2008, the in-process development and redevelopment properties included three buildings that were under construction and three lease-up properties, which will encompass an aggregate of approximately 611,000 rentable square feet of new office space. All of the in-process development and redevelopment properties are in the San Diego region of Southern California, except for one redevelopment property, which is in El Segundo, California.

The Company owns its interests in all of its Office Properties and Industrial Properties through Kilroy Realty, L.P. (the “Operating Partnership”) and Kilroy Realty Finance Partnership, L.P. (the “Finance Partnership”). The Company conducts substantially all of its operations through the Operating Partnership, in which it owned a 93.7% general partnership interest as of March 31, 2008. The remaining 6.3% common limited partnership interest in the Operating Partnership as of March 31, 2008, was owned by certain of the Company’s executive officers and directors, certain of their affiliates, and other outside investors (see Note 4). 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. The Company conducts substantially all of its 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. With the exception of the Operating Partnership, all of the Company’s subsidiaries are wholly-owned.

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. All significant intercompany balances and transactions have been eliminated in the consolidated financial statements. The Company also consolidates all variable interest entities (“VIEs”) in which it is deemed to be the primary beneficiary in accordance with Financial Accounting Standards Board (“FASB”) Interpretation No. 46R, Consolidation of Variable Interest Entities. The Company had no VIEs at March 31, 2008 or December 31, 2007.

KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The accompanying interim financial statements have been prepared by the Company’s 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, 2008. These financial statements 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, 2007.

Accounting Pronouncements Adopted January 1, 2008

Effective January 1, 2008, the Company adopted, on a prospective basis, Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS 157”) as amended by FASB Staff Position SFAS 157-1, “Application of FASB Statement No. 157 to FASB Statement No. 13 and Other Accounting Pronouncements That Address Fair Value Measurements for Purposes of Lease Classification or Measurement under Statement 13” (“FSP FAS 157-1”) and FASB Staff Position SFAS 157-2, “Effective Date of FASB Statement No. 157” (“FSP FAS 157-2”). SFAS 157 defines fair value, establishes a framework for measuring fair value in GAAP and provides for expanded disclosure about fair value measurements. SFAS 157 applies prospectively to all other accounting pronouncements that require or permit fair value measurements. FSP FAS 157-1 amends SFAS 157 to exclude from the scope of SFAS 157 certain leasing transactions accounted for under Statement of Financial Accounting Standards No. 13, “Accounting for Leases.” FSP FAS 157-2 amends SFAS 157 to defer the effective date of SFAS 157 for all non-financial assets and non-financial liabilities except those that are recognized or disclosed at fair value in the financial statements on a recurring basis to fiscal years beginning after November 15, 2008.

The adoption of SFAS 157 did not have a material impact on the Company’s consolidated financial statements. Management is evaluating the impact that SFAS 157 will have on its non-financial assets and non-financial liabilities since the application of SFAS 157 for such items was deferred to January 1, 2009. The Company believes that the impact of these items will not be material to its consolidated financial statements. Assets and liabilities typically recorded at fair value on a non-recurring basis to which the Company has not yet applied SFAS 157 due to the deferral of SFAS 157 for such items include:

•

Non-financial assets and liabilities initially measured at fair value in an acquisition or business combination

•

Long-lived assets measured at fair value due to an impairment assessment under Statement of Financial Accounting Standards No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets”

•

Asset retirement obligations initially measured under Statement of Financial Accounting Standards No. 143, “Accounting for Asset Retirement Obligations”

Effective January 1, 2008, the Company adopted, on a prospective basis, Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS 159”). SFAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value. The objective of the guidance is to improve financial reporting by providing entities with the opportunity to mitigate

KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. The adoption of SFAS 159 did not have a material impact on the Company’s consolidated financial statements since the Company did not elect to apply the fair value option for any of its eligible financial instruments or other items on the January 1, 2008 effective date.

Recent Accounting Pronouncements

In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161 “Disclosures about Derivative Instruments and Hedging Activities” (“SFAS 161”). This new standard enhances disclosure requirements for derivative instruments in order to provide users of financial statements with an enhanced understanding of (i) how and why an entity uses derivative instruments, (ii) how derivative instruments and related hedged items are accounted for under Financial Accounting Standards No. 133 “Accounting for Derivative Instruments and Hedging Activities” and its related interpretations and (iii) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. SFAS 161 is to be applied prospectively for the first annual reporting period beginning on or after November 15, 2008. The Company believes that the adoption of SFAS 161 will not have a material impact on the Company’s financial statement disclosures since the Company does not currently have any derivative instruments.

In December 2007, the FASB issued Statement of Financial Accounting Standards No. 141(R) “Business Combinations” (“SFAS 141(R)”) and Statement of Financial Accounting Standards No. 160 “Noncontrolling Interests in Consolidated Financial Statements—An Amendment of ARB No. 51” (“SFAS 160”). These two new standards will significantly change the accounting for, and reporting of, business combination transactions and noncontrolling (minority) interests in consolidated financial statements. SFAS 141(R) requires an acquiring entity to recognize acquired assets and assumed liabilities in a transaction at fair value as of the acquisition date, changes the disclosure requirements for business combination transactions and changes the accounting treatment for certain items, including contingent consideration agreements which will be required to be recorded at acquisition date fair value and acquisition costs which will be required to be expensed as incurred. SFAS 160 requires that noncontrolling interests be presented as a component of consolidated stockholders’ equity, eliminates “minority interest accounting” such that the amount of net income attributable to the noncontrolling interests will be presented as part of consolidated net income on the consolidated statement of operations and not as a separate component of income and expense, and requires that upon any changes in ownership that result in the loss of control of the subsidiary, the noncontrolling interest be re-measured at fair value with the resultant gain or loss recorded in net income. SFAS 141(R) and SFAS 160 require concurrent adoption and are to be applied prospectively for the first annual reporting period beginning on or after December 15, 2008. Early adoption of either standard is prohibited. Management is currently evaluating the impact of these statements on the Company’s consolidated financial statements.

In August 2007, the FASB proposed FASB Staff Position APB 14-a “Accounting for Convertible Debt Instruments That May Be Settled Upon Conversion (Including Partial Cash Settlement)” (“Proposed FSP APB 14-a”). Proposed FSP APB 14-a, if approved, would require the initial proceeds from convertible debt that may be settled in cash to be bifurcated between a liability component and an equity component. The objective of the guidance is to require the liability and equity components of convertible debt to be separately accounted for in a manner such that the interest expense recorded on the convertible debt would not equal the contractual rate of interest on the convertible debt, but instead would be recorded at a rate that would reflect the issuer’s conventional debt borrowing rate. This is accomplished through the creation of a discount on the debt that would be accreted using the effective interest method as additional non-cash interest expense over the period the debt is expected to remain outstanding. In March 2008, the FASB directed its staff to proceed to draft Proposed FSP APB 14-a for vote by written ballot. The Company believes that Proposed FSP APB 14-a, if approved, would

KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

impact the accounting for the Company’s 3.25% Exchangeable Senior Notes (the “Notes”) and would have a material impact on the Company’s consolidated financial statements and results of operations. The provisions of Proposed FSP APB 14-a, if approved, would be applied retrospectively to all periods presented.

2. Unsecured and Secured Debt

Secured Debt

In February 2008, the City of Carlsbad issued public facility bonds (the “Bonds”), the proceeds from which were used to finance infrastructure improvements on one of the Company’s undeveloped land parcels. Of the Company’s $3.5 million maximum obligation under the Bonds, $2.8 million was assessed to the Company and included in secured debt on the consolidated balance sheet at March 31, 2008 since the Company’s obligation was fixed and determinable. Principal and interest payments for the Bonds will be charged to the Company through the assessment of special property taxes.

Exchangeable Senior Notes

In March 2008, the exchange rate for the Notes was adjusted by 0.05% for the 4.5% increase in the Company’s dividend per common share approved by the Company’s Board of Directors in February 2008. This adjustment was made pursuant to the original terms of the Notes since the exchange rate for the Notes is subject to adjustment under certain circumstances, including increases in the Company’s common dividends. The Notes had an initial exchange rate of 11.3580 common shares per $1,000 principal amount of the Notes, which was equivalent to an exchange price of $88.04 per common share and a conversion premium of approximately 20.0% based on a price of $73.37 per share of the Company’s common stock on March 27, 2007. The exchange rate was adjusted to 11.3636 common shares per $1,000 principal amount of the Notes, which is equivalent to an exchange price of $88.00 per common share and a conversion premium of approximately 19.94% based on a price of $73.37 per share of the Company’s common stock on March 27, 2007.

Unsecured Line of Credit

The Company has a $550 million unsecured line of credit (the “Credit Facility”), under which the Company may elect to borrow up to an additional $100 million under an increase option. As of March 31, 2008, the Company had borrowings of $137 million outstanding under the Credit Facility and availability of approximately $413 million. The Credit Facility bears interest at an annual rate between LIBOR plus 0.85% and LIBOR plus 1.35% depending upon the Company’s leverage ratio at the time of borrowing (3.7% at March 31, 2008). The Credit Facility matures in April 2010 with an option to extend the maturity for one year. The fee for unused funds under the Credit Facility ranges from an annual rate of 0.15% to 0.20% depending on the Company’s leverage ratio. The Company expects to use the Credit Facility to finance development and redevelopment expenditures, to fund potential acquisitions and for other general corporate uses.

Debt Covenants and Restrictions

The 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 assets, a maximum ratio of total secured debt to total assets, a fixed charge coverage ratio, a minimum consolidated tangible net worth and a limit of the ratio of development activities to total assets. In addition, one of the Company’s loan covenants prohibits the Company from paying dividends in excess of 95% of funds from operations (“FFO”). 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. The Company was in compliance with all of its debt covenants at March 31, 2008.

Total	$	72,573	$	59,187

Deferred revenue related to tenant-funded tenant improvements

During the three months ended March 31, 2008, the Company recorded an additional $15.6 million of deferred revenue related to tenant-funded tenant improvements. This amount primarily represents the cost of the tenant improvements paid for or reimbursed by the tenant in connection with three significant leases. The deferred revenue related to these tenant-funded tenant improvements will be amortized as additional rental income over the term of the related lease beginning upon the substantial completion of the respective properties.

During the three months ended March 31, 2008 and 2007, $1.8 million and $0.6 million, respectively, of deferred revenue related to tenant-funded tenant improvements was amortized and recognized as rental income. The following is the estimated amortization of deferred revenue related to tenant-funded tenant improvements at March 31, 2008 for the remainder of 2008, the next five years and thereafter:

4. Minority Interests

Common Limited Partnership Unitholders

The Company owned a 93.7%, 93.7% and 93.5% common general partnership interest in the Operating Partnership as of March 31, 2008, December 31, 2007 and March 31, 2007, respectively. The remaining 6.3%, 6.3% and 6.5% common limited partnership interest as of March 31, 2008, December 31, 2007 and March 31, 2007, respectively, was owned by certain of the Company’s executive officers and directors, certain of their affiliates, and other outside investors in the form of common limited partnership units. The common limited partnership units may be redeemed by unitholders for cash. The Company may, at its option, satisfy the cash redemption obligation with shares of the Company’s common stock. The redemption value for each common limited partnership unit of the Operating Partnership as of any balance sheet date 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 New York Stock Exchange (“NYSE”) for the ten trading days immediately preceding the respective balance sheet date. Accordingly, as of March 31, 2008 and December 31, 2007, the aggregate redemption value of the then-outstanding common limited partnership units of the Operating Partnership was $107.3 million and $119.3 million, respectively.

5. Stockholders’ Equity

Share Repurchases

During the three months ended March 31, 2008, the Company repurchased 159,657 shares of its common stock in open market transactions for an aggregate price of approximately $7.6 million, or $47.54 per share. These repurchases were made pursuant to a share repurchase program approved by the Company’s Board of Directors and were funded through borrowings on the Company’s Credit Facility. As of March 31, 2008, an aggregate of 1,067,843 shares remained eligible for repurchase under this share repurchase program.

During the three months ended March 31, 2008, the Company accepted the return, at the current quoted market price, of 56,779 shares of its common stock from certain key employees in accordance with the provisions of its incentive stock plan to satisfy minimum statutory tax-withholding requirements related to shares that vested during this period.

6. Share-Based Compensation

Share-Based Incentive Plan

At March 31, 2008, the Company had one share-based incentive compensation plan under which awards were available to be granted, the Kilroy Realty 2006 Incentive Award Plan (the “2006 Plan”). At March 31, 2008, there were 1,127,541 shares and share-based awards available to be granted under the 2006 Plan. The following summarizes the share-based compensation programs approved and the share-based awards granted during the three months ended March 31, 2008 as well as a summary of the 2007 program for the Executive Officers that was still in the performance period as of March 31, 2008.

Executive Officer Share-Based Compensation Programs

In January 2008, the Executive Compensation Committee approved the 2008 Annual Long-Term Incentive Program, which allows the executive officers to receive bonus compensation in the event certain specified corporate performance measures are achieved for the fiscal year ending December 31, 2008. It is anticipated that such awards will be paid in nonvested shares or, if available and at the applicable employee’s option, in other equity-based instruments that, subject to vesting and other conditions, may become exchangeable on a

KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

one-for-one basis for shares of the Company’s common stock or cash, at the election of the Company. The Company anticipates that any nonvested shares or other equity-based instruments earned under this program would be issued during the first quarter of 2009. Individual awards earned under the 2008 Annual Long-Term Incentive Program would vest in two equal installments on December 31, 2009 and December 31, 2010. Vesting will be based on continued employment through the applicable vesting dates.

As of March 31, 2008, the Company was still in the performance period for the Development Performance Program (“DPP”), which was approved by the Company’s Executive Compensation Committee in 2007. The incentive award that may be earned under the DPP will be based on whether certain future specified development completion and leasing targets are achieved for development and redevelopment properties on which the Company commenced construction during 2007. During the DPP performance period, the Company records compensation expense at the end of each reporting period by evaluating the likelihood of achieving the specified targets and estimating the timeframe in which the targets could potentially be achieved and then recording compensation cost on the applicable portion of the estimated performance period that has elapsed before the end of the period. Performance is measured independently for the development completion and development leasing components of the DPP. If the development completion and development leasing targets are individually not achieved, no award would be earned under that component of the DPP. The Company currently estimates that any nonvested shares or other equity-based instruments that could potentially be earned under the development completion component of the DPP would be granted in the second half of 2008, and any nonvested shares or other equity-based instruments that could potentially be earned under the development leasing component of the DPP would be granted in the first half of 2009.

Key Employee Share-Based Compensation Program

In February 2008, the Executive Compensation Committee granted an aggregate of 82,303 nonvested shares of common stock to certain key employees. The total compensation cost for the nonvested stock grants was calculated based on the quoted closing share price of the Company’s common stock on the NYSE of $49.21 on the grant date of February 5, 2008. These shares vest in equal annual installments on December 31^st of each year over a five-year period.

Summary of nonvested shares of common stock

A summary of the status of the Company’s nonvested shares as of January 1, 2008 and changes during the three months ended March 31, 2008, is presented below:


Nonvested Shares	Shares		Weighted- Average Grant-Date Fair Value
Nonvested at January 1, 2008	237,833		$	80.35
Granted⁽¹⁾	182,378			52.37
Vested	(46,736	)		59.84

Nonvested at March 31, 2008	373,475		$	69.03

(1)	Includes 100,075 nonvested shares awarded to the executive officers on December 31, 2007 under the 2007 Annual Long-Term Incentive Program, which were issued and outstanding on January 1, 2008.

The total compensation cost for all share-based compensation programs was $3.8 million and $3.6 million for the three months ended March 31, 2008 and 2007, respectively. Of the total share-based compensation cost, $0.3 million and $0.2 million were capitalized as part of real estate assets for the three months ended March 31,

KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

2008 and 2007, respectively. As of March 31, 2008, there was approximately $16.2 million of total unrecognized compensation cost related to nonvested shares granted under share-based compensation arrangements that is expected to be recognized over a weighted-average period of 1.8 years. The remaining compensation cost related to these nonvested shares had been recognized in periods prior to March 31, 2008. The $16.2 million of unrecognized compensation cost does not reflect the potential future compensation cost for the 2008 Annual Long-Term Incentive Program or the DPP discussed above since share-based awards have not been granted under these programs as of March 31, 2008. The compensation cost that will be recorded in future periods related to these programs will be based on the amounts ultimately earned under these programs.

The total fair value of shares that vested during the three months ended March 31, 2008 was $2.3 million, 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.

7. Commitments and Contingencies

In March 2008, a tenant at one of the Company’s Office Properties ceased paying rent and attempted to surrender the leased premises back to the Company prior to the end of the lease term. The Company refused to accept a surrender of the premises and has initiated legal action against this tenant for past due rent and future rent as it becomes due and owing. In the event there is ultimately an unfavorable result to the Company, the Company believes that there could potentially be a significant negative non-cash impact to the Company’s results of operations ranging between $0 and approximately $3.5 million, primarily related to the deferred rent receivable balance for this tenant at March 31, 2008.

8. Financial Instruments Recorded at Fair Value

The assets held in connection with the Company’s 2007 Deferred Compensation Plan (the “Plan”) and the corresponding liability to the participants are measured at fair value on a recurring basis on the Company’s consolidated balance sheet. The assets are treated as trading securities for accounting purposes and reported as marketable securities on the Company’s consolidated balance sheet. The liability is adjusted to fair value at the end of each accounting period based on the performance of the benchmark funds selected by each participant in the Plan and reported in accounts payable, accrued expenses and other liabilities in the Company’s consolidated balance sheet.

9. Segment Disclosure

The Company’s reportable segments consist of the two types of commercial real estate properties for which the Company’s chief operating decision-makers internally evaluate operating performance and financial results: Office Properties and Industrial Properties. The Company also has certain corporate level activities including legal administration, accounting, finance and management information systems, which are not considered separate operating segments.

The Company evaluates the performance of its 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 income and expenses, interest expense, depreciation and amortization and corporate general and administrative expenses. There is no intersegment activity.

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. 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 investment amounts. Although the information is based on our current expectations, actual results could vary from expectations stated in this report. Numerous factors will affect our actual results, some of which are beyond our control. These include the timing and strength of regional economic growth, the strength of commercial and industrial real estate markets, market conditions affecting tenants, competitive market conditions, fluctuations in availability and cost of construction materials resulting from the effects of increased worldwide demand, increased labor costs, future 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 of this report. We assume no obligation to update publicly any forward-looking information, whether as a result of new information, future events or otherwise, except to the extent we are required to do so in connection with our ongoing requirements under federal securities laws to disclose material information. For a discussion of important risks related to our business, and related to investing in our securities, including risks that could cause actual results and events to differ materially from results and events referred to in the forward-looking information, see “Item 1A—Risk Factors” in our annual report on Form 10-K for the fiscal year ended December 31, 2007 and the discussion under the captions “—Factors That May Influence Future Results of Operations” and “—Liquidity and Capital Resources—Factors That May Influence Future Sources of Capital and Liquidity” below. In light of these risks, uncertainties and assumptions, the potential circumstances or events expressed or implied by the forward-looking statements in this report might not occur.

Overview and Background

We own, operate and develop office and industrial real estate in Southern California. We operate as a self-administered REIT. We own our interests in all of our properties through the Operating Partnership and the Finance Partnership, and we conduct substantially all of our operations through the Operating Partnership. We owned a 93.7%, 93.7% and 93.5% general partnership interest in the Operating Partnership as of March 31, 2008, December 31, 2007 and March 31, 2007, respectively.

Factors That May Influence Future Results of Operations

Rental rates. For leases that commenced during the three months ended March 31, 2008, the change in rental rate was an increase of 49.3% on a GAAP basis and an increase of 28.6% on a cash basis. The change in rental rate on a cash basis is calculated as the change between the initial stated rent for a new or renewed lease and the ending stated rent for the expiring lease for the same space, whereas the change in rental rate on a GAAP basis compares the average rents over the term of the lease for each lease. Both calculations exclude leases for which the space was vacant longer than one year. We believe that at March 31, 2008 the average rental rates for our properties were approximately 15% below the current average quoted market rates, although individual properties within any particular submarket presently may be leased either above, below or at the current quoted market rates within that region. 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 quoted market rates. Our occupancy and rental rates are impacted by general economic conditions, including the pace of regional economic growth and access to capital. An extended economic slowdown and tightening of the credit markets could have an adverse affect on our tenants and, as a result, on our future occupancy and rental rates.

Scheduled lease expirations. In addition to the 619,300 rentable square feet, or 5.2%, of currently available space in our stabilized portfolio, leases representing approximately 7.5% and 17.6% of the leased

square footage of our stabilized portfolio are scheduled to expire during the remainder of 2008 and in 2009, respectively. The leases scheduled to expire during the remainder of 2008 and the leases scheduled to expire in 2009 represent approximately 1.7 million rentable square feet of office space, or 16.5% of our total annualized base rental revenue, and 1.2 million rentable square feet of industrial space, or 3.5% of our total annualized base rental revenue, respectively. We believe that the average rental rates for leases scheduled to expire during the remainder of 2008 and in 2009 are approximately 10% to 15% below the current average quoted market rates, although individual properties within any particular submarket presently may be leased either above, below or at the current quoted market rates within that submarket. Our ability to re-lease available space depends upon the market conditions in the specific regions in which our properties are located.

Sublease space. Of our leased space as of March 31, 2008, approximately 504,000 rentable square feet, or 4.2%, of the rentable square footage in our stabilized portfolio, was available for sublease, compared to approximately 608,100 rentable square feet, or 5.1%, as of December 31, 2007. Of the 4.2% of available sublease space in our stabilized portfolio as of March 31, 2008, approximately 1.7% was vacant space, and the remaining 2.5% was occupied. Approximately 39%, 38% and 23% of the available sublease space as of March 31, 2008 is located in the Orange County, San Diego and Los Angeles regions, respectively. Of the approximately 504,000 rentable square feet available for sublease as of March 31, 2008, approximately 82,000 rentable square feet representing five leases are scheduled to expire during the remainder of 2008, and approximately 7,401 rentable square feet representing two leases are scheduled to expire in 2009.

Negative trends or other unforeseeable events that impair our ability to renew or re-lease space and our ability to maintain or increase rental rates in our regions could have an adverse effect on our future financial condition, results of operations and cash flows.

Rising Construction Costs. As a result of increased worldwide demand, the availability of construction materials has become more limited, and the cost of such materials has increased significantly. However, the cost of skilled labor is moderating. A continued increase in the cost of construction materials, driven primarily by the volatility of the prices of underlying raw materials such as oil, cement and steel, and labor costs could adversely affect our expenditures for development and redevelopment costs and, consequently, our financial condition, results of operations and cash flows.

City of San Diego. Given the geographic concentration of our development program in San Diego County, our operating results may be affected by (i) the city of San Diego’s current financial difficulties and ongoing investigations with respect to the city’s finances, (ii) the city of San Diego’s General Plan and Land Use update, (iii) the city of San Diego’s zoning ordinance updates and (iv) recent storm water runoff regulations and other pending ordinances currently under consideration by the city, county and state water agencies and other agencies. Any of these factors may affect the city of San Diego’s ability to finance capital projects and may impact real estate development, entitlements, costs of development and market conditions in this important submarket. As of the date of this report, we have not experienced any material adverse effects arising from these factors.

Incentive Compensation. Our Executive Compensation Committee, which is currently comprised of three independent directors, 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 certain performance measures, including financial, operating and development targets.

In the first quarter of 2008, our Executive Compensation Committee approved the 2008 Annual Bonus Program and the 2008 Annual Long-Term Incentive Program for executive management that will allow for executive management to receive bonus compensation for achieving certain specified corporate performance measures. The provisions of the 2008 programs were reported on Form 8-K filed with the SEC on January 31, 2008. As a result of the structure of these programs and other such programs that the Executive Compensation Committee may adopt in the future, accrued incentive compensation and compensation expense will be affected

by our operating and development performance, financial results, the performance of our common stock and market conditions. Consequently, we cannot predict with certainty the amounts that will be recorded in future periods related to compensation programs.

Share-Based Compensation. As of March 31, 2008, there was $16.2 million of total unrecognized compensation cost related to outstanding nonvested shares issued under share-based compensation arrangements. That cost is expected to be recognized over a weighted-average period of 1.8 years. The $16.2 million of unrecognized compensation cost does not reflect the potential future compensation cost for the 2007 Development Performance Program or the 2008 Annual Long-Term Incentive Program since any share-based awards have not been granted under these programs as of March 31, 2008. The compensation cost that will be recorded in future periods related to these programs will be based on the amounts ultimately earned under these programs. (See Note 6 to our consolidated financial statements included with this report for additional information).

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 from continuing operations (rental income, tenant reimbursements and other property income) less operating expenses from continuing operations (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 consists of the same net operating income segment information disclosed in Note 9 to our consolidated financial statements in accordance with Statement of Financial Accounting Standards No. 131 “Disclosures about Segments of an Enterprise and Related Information.”

Operating Revenues

Total revenues from Office Properties increased $8.7 million, or 16.2%, to $62.5 million for the three months ended March 31, 2008, compared to $53.8 million for the three months ended March 31, 2007.

•

Of this increase, $6.5 million was due to the following:

•

An increase of $5.9 million in rental income generated by the five office development properties that were added to the stabilized portfolio in the third quarter of 2007 (the “2007 Office Development Properties”); and

•

An increase of $0.6 million in rental income generated by one property that was taken out of service in June 2006 and placed into lease-up in the third quarter of 2007 and a project consisting of two buildings that was acquired in the first quarter of 2007 and placed into lease-up in the fourth quarter of 2007 (the “2007 Office Redevelopment Properties”).

•

•

An increase of $0.3 million generated in rental income primarily from our Los Angeles Core Office Portfolio partially offset by a decrease in rental income from our San Diego Core Office Portfolio.

•

Average occupancy increased 3.5% in the Los Angeles Core Office Portfolio to 96.2% for the three months ended March 31, 2008, from 92.7% for the three months ended March 31, 2007; and

•

An increase of $0.7 million, or 13.8%, was generated by the Core Office Portfolio due to an increase in reimbursable property expenses as discussed below.

•

An increase of $0.9 million, or 10.0%, was generated by the Core Office Portfolio. This increase was primarily attributable to general increases in certain operating costs such as property management costs of $0.5 million, repairs and maintenance costs of $0.2 million, and janitorial and other service-related costs of $0.2 million.

•

Real Estate Taxes

Real estate taxes from Office Properties increased $0.9 million, or 23.2%, to $4.8 million for the three months ended March 31, 2008, compared to $3.9 million for the three months ended March 31, 2007, due to the following:

The increase in tenant reimbursements was primarily attributable to an increase in reimbursable property expenses due to the increase in occupancy in the Core Industrial Portfolio.

Property and Related Expenses

Total expenses from Industrial Properties increased $0.3 million, or 25.3%, to $1.6 million for the three months ended March 31, 2008, compared to $1.3 million for the three months ended March 31, 2007.

Provision for Bad Debts

The provision for bad debts for Industrial Properties increased by $0.1 million, or 188.9%, for the three months ended March 31, 2008, compared to the three months ended March 31, 2007, primarily due to changes in our estimates of the collectibility of receivables from certain watchlist tenants.

Other Income and Expenses

Interest Expense

The following table sets forth our gross interest expense and loan cost amortization from continuing operations net of capitalized interest and loan cost amortization for the three months ended March 31, 2008 and 2007.


	Three Months Ended March 31,						Dollar Change			Percentage Change
	2008			2007			Dollar Change			Percentage Change
	($ in thousands)

Interest expense	$	9,713		$	9,656		$	57		0.6	%

The $0.2 million decrease in gross interest and loan fee expense before the effect of capitalized interest and loan for the three months ended March 31, 2008 compared to the three months ended March 31, 2007 was primarily attributable to:

•

A decrease in our weighted-average interest rate from 6.33% for the three months ended March 31, 2007 to 4.98% for the three months ended March 31, 2008;

•

This decrease was largely offset by an increase in our average debt balance associated with our development activities and the repurchase of shares of our common stock during the three months ended March 31, 2008 compared to the three months ended March 31, 2007.

The $0.2 million decrease in total capitalized interest and loan fees for the three months ended March 31, 2008 compared to the three months ended March 31, 2007 was primarily attributable to:

•

A decrease in our weighted-average interest rate from 6.33% for the three months ended March 31, 2007 to 4.98% for the three months ended March 31, 2008;

•

This decrease was largely offset by higher average balances eligible for capitalization during the three months ended March 31, 2008 compared to the three months ended March 31, 2007.

Depreciation and Amortization Expense

Depreciation and amortization expense increased $3.0 million, or 17.9%, to $19.9 million for the three months ended March 31, 2008 compared to $16.9 million for the three months ended March 31, 2007. This increase was primarily attributable to:

•

A $2.2 million increase from the 2007 Office Development Properties, which were added to the stabilized portfolio;

•

A $0.5 million increase from the Core Office Portfolio; and

•

A $0.3 million increase from the 2007 Office Redevelopment Properties, which were placed into lease-up.

Other Income

Total other income decreased approximately $0.5 million, or 74.6%, for the three months ended March 31, 2008 compared to the three months ended March 31, 2007. This decrease was primarily attributable to:

•

A $0.2 million decrease due to interest earned in January 2007 on the funds held at a qualified intermediary for an exchange of real property pursuant to Section 1031 of the Internal Revenue Code (a “Section 1031 Exchange”). In January 2007, we used these funds to partially fund two acquisitions to complete a Section 1031 Exchange.

•

A $0.3 million decrease largely due to lower cash balances and interest rates during the three months ended March 31, 2008 compared to the three months ended March 31, 2007.

Development and Redevelopment Programs

We believe that a significant portion of our potential growth over the next several years will continue to come from our development pipeline. We continue to seek and obtain development opportunities throughout Southern California and specifically in our core markets. We have made significant progress in expanding our development program through targeted acquisitions of redevelopment opportunities and undeveloped land.

In February 2008, we signed two lease agreements with Bridgepoint Education, Inc. (“Bridgepoint”) totaling approximately 289,700 rentable square feet. Commencing in stages in the third quarter of 2008, Bridgepoint will lease 100% of the approximately 147,500 rentable square feet at Kilroy Sabre Springs Phase III, which is currently under construction. In the third quarter of 2009, Bridgepoint will expand its occupancy at 13500 Evening Creek Drive from approximately 119,800 rentable square feet at March 31, 2008 to approximately 142,200 rentable square feet. Both leases are scheduled to expire in June 2018. Bridgepoint is currently projected to become our second largest tenant in the third quarter of 2009, based on its percentage of our projected total annualized base rental revenues.

The following table sets forth certain information regarding our office development properties in-process as of March 31, 2008.

We believe that another possible source of potential growth over the next several years is redevelopment opportunities within our existing portfolio or targeted acquisitions. Redevelopment efforts can achieve similar returns to new development with reduced entitlement risk and shorter construction periods. Depending on market conditions, we will continue to pursue future redevelopment opportunities in our strategic submarkets where there is limited land for development.

The following table sets forth certain information regarding our office redevelopment properties in lease-up as of March 31, 2008.

We have a proactive planning process by which we continually evaluate the size, timing, costs and scope of our development and redevelopment programs and, as necessary, scale activity to reflect the economic conditions and the real estate fundamentals that exist in our strategic submarkets. However, we may be unable to lease committed development or redevelopment properties at expected rental rates or within projected timeframes or complete development or redevelopment properties on schedule or within budgeted amounts, which could adversely affect our financial condition, results of operations and cash flows.

Liquidity and Capital Resources

Current Sources of Capital and Liquidity

We seek to create and maintain a capital structure that allows for financial flexibility and diversification of capital resources. Our primary source of liquidity to fund distributions, debt service, leasing costs and maintenance-related capital expenditures is net cash from operations. We believe that we will have sufficient capital resources to satisfy our liquidity needs over the next twelve-month period. Our primary sources of liquidity to fund development and redevelopment costs, potential undeveloped land and property acquisitions, temporary working capital and unanticipated cash needs are the Credit Facility, proceeds received from our property disposition program, construction loans and the public or private issuance of debt or equity securities. As of March 31, 2008, our total debt as a percentage of total market capitalization was 37.2%, and our total debt and liquidation value of our preferred equity as a percentage of total market capitalization was 43.8%.

As of March 31, 2008, we had borrowings of $137 million outstanding under the Credit Facility and availability of approximately $413 million. The Credit Facility bears interest at an annual rate between LIBOR plus 0.85% and LIBOR plus 1.35%, depending upon our leverage ratio at the time of borrowing (3.70% at March 31, 2008). We expect to use the Credit Facility to finance development and redevelopment expenditures, to fund potential acquisitions and for other general corporate uses.

Factors That May Influence Future Sources of Capital and Liquidity

One of our fixed-rate mortgage notes payable has a principal balance of $73.0 million and is scheduled to mature in August 2008. We are currently evaluating potential sources of refinancing, including the borrowing of up to $73.0 million from the Credit Facility to repay this loan.

During the three months ended March 31, 2008, we repurchased 159,657 shares of our common stock in open market transactions for an aggregate price of approximately $7.6 million, or $47.54 per share. These repurchases were made pursuant to a share repurchase program approved by our Board of Directors and were funded through borrowings on our Credit Facility. As of March 31, 2008, an aggregate of 1,067,843 shares remained eligible for repurchase under this share repurchase program. We may opt to repurchase additional shares of our common stock in the future depending upon market conditions.

Our Credit Facility, unsecured senior notes and certain other secured debt agreements contain covenants and restrictions requiring us to meet certain financial ratios and reporting requirements. Some of the more restrictive covenants include a maximum ratio of total debt to total assets, a maximum ratio of total secured debt to total assets, a fixed charge coverage ratio, a minimum consolidated tangible net worth, a limit of the ratio of development activities to total assets and a maximum ratio of dividend payments to FFO. Non-compliance with one or more of the covenants or 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 our debt covenants at March 31, 2008.

Debt Composition

The composition of our aggregate debt balances at March 31, 2008 and December 31, 2007 was as follows:


	Percentage of Total Debt				Weighted Average Interest Rate
	March 31, 2008		December 31, 2007		March 31, 2008		December 31, 2007
Secured vs. unsecured:

Off-Balance Sheet Arrangements

As of March 31, 2008 and as of the date this report was filed, we do not have any off-balance sheet transactions, arrangements or obligations, including contingent obligations.

Historical Cash Flows

The principal sources of funding for our future development, redevelopment, acquisitions, share repurchases and capital expenditures are cash flow from operating activities, the Credit Facility, secured and unsecured debt financing and proceeds from our dispositions. The following is a summary of the sources and uses of cash for the three months ended March 31, 2008, compared to the three months ended March 31, 2007.


	Three Months Ended March 31,
	2008			2007			Dollar Change			Percentage Change
	($ in thousands)
Net cash provided by operating activities	$	31,510		$	34,662		$	(3,152	)	(9.1	)%
Net cash used in investing activities		(26,518	)		(67,535	)		41,017		(60.7	)
Net cash (used in) provided by financing activities		(11,843	)		26,092			(37,935	)	(145.4	)

Operating Activities

Our net cash provided by operating activities decreased by $3.2 million, or 9.1%, to $31.5 million for the three months ended March 31, 2008 compared to $34.7 million for the three months ended March 31, 2007.

•

A $9.0 million decrease in cash provided by operating activities was primarily attributable to the following:

•

An approximate $5.3 million decrease in cash received from tenants for reimbursement of tenant-funded tenant improvements during the three months ended March 31, 2008 compared to the three months ended March 31, 2007.

•

An approximate $3.6 million increase in cash incentive compensation paid during the three months ended March 31, 2008 compared to the three months ended March 31, 2007.

•

This $9.0 million decrease was partially offset by increases in cash provided by operating activities primarily attributable to the following:

•

An approximate $3.8 million decrease in cash paid for interest (net of capitalized interest, which is included in investing activities) during the three months ended March 31, 2008 compared to the three months ended March 31, 2007. This decrease is due primarily to a change in the composition of the Company’s debt structure as a result of the issuance of the Notes in April 2007 and the corresponding impact of the timing of interest payments.

•

An approximate $2.0 million increase in cash flow from property operations for the three months ended March 31, 2008 compared to the three months ended March 31, 2007.

Investing Activities

Net cash used in investing activities decreased by $41.0 million, or 60.7%, to $26.5 million for the three months ended March 31, 2008, compared to $67.5 million for the three months ended March 31, 2007. The change was primarily attributable to the following:

•

A decrease in development expenditures of $28.0 million for the three months ended March 31, 2008 compared to the three months ended March 31, 2007.

•

A decrease in expenditures for operating properties of $5.3 million for the three months ended March 31, 2008 compared to the three months ended March 31, 2007.

•

A decrease of $7.7 million in net expenditures for acquisitions for the three months ended March 31, 2008 compared to the three months ended March 31, 2007. During the three months ended March 31, 2007, we had three acquisitions for an aggregate purchase price of $69.0 million and net proceeds received from property dispositions of $61.3 million, resulting in $7.7 million of net acquisition expenditures. We did not acquire or dispose of any properties or undeveloped land during the three months ended March 31, 2008.

Financing Activities

Net cash used in financing activities fluctuated by $37.9 million, or 145.4%, to $11.8 million for the three months ended March 31, 2008, compared to $26.1 million provided by financing activities for the three months ended March 31, 2007. The change was primarily attributable to the following:

•

We used approximately $7.6 million to repurchase 159,657 shares of our common stock pursuant to a share repurchase program approved by our Board of Directors during the three months ended March 31, 2008. We did not repurchase any shares under this program during the three months ended March 31, 2007. (See Note 5 to our consolidated financial statements included with this report for additional information).

•

We borrowed $29.0 million less under our Credit Facility during the three months ended March 31, 2008 compared to the three months ended March 31, 2007, primarily due to a decrease in development expenditures and other investing activities as noted above.

•

Dividends and distributions paid to common stockholders and common unitholders increased by $1.0 million for the three months ended March 31, 2008 compared to the three months ended March 31, 2007 due primarily to an increase in the dividend rate.

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 to be insufficient by themselves. Because FFO excludes depreciation and amortization of real estate assets, we believe that FFO along with the required GAAP presentations provides a more complete measurement of our performance relative to our competitors and a more appropriate basis on which to make decisions involving operating, financing and investing activities than the required GAAP presentations alone would provide.

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

The following table presents our FFO for the three months ended March 31, 2008 and 2007:


	Three Months Ended March 31,
	2008		2007
	($ in thousands)
Net income available for common stockholders	$	9,864	$	16,478

Funds From Operations⁽¹⁾	$	30,199	$	26,021

(1)	Reported amounts are attributable to our common stockholders and common unitholders of the Operating Partnership.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary market risk we face is interest rate risk. We mitigate this risk by maintaining prudent amounts of leverage, minimizing interest expense while continuously evaluating all available debt and equity resources and following established risk management policies and procedures that may include the periodic use of derivative instruments. As of March 31, 2008 and 2007, we did not have any derivative instruments.

Information about our changes in interest rate risk exposures from December 31, 2007 to March 31, 2008 is incorporated herein by reference from “Item 2: Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.”

Tabular Presentation of Market Risk

The tabular presentation below provides information about our interest rate sensitive financial instruments at March 31, 2008 and December 31, 2007.

ITEM 4. CONTROLS

AND PROCEDURES

We maintain disclosure controls and procedures (as defined in Rule 13a-15(e) or Rule 15d-15(e) under the Securities Exchange Act of 1934, as amended) that are designed to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934, as amended, is processed, recorded, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As required by SEC Rule 13a-15(b), we carried out an evaluation, under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the disclosure controls and procedures as of March 31, 2008, the end of the period covered by this report.

Based on the foregoing, the Chief Executive Officer and Chief Financial Officer concluded, as of that time, that our disclosure controls and procedures were effective at the reasonable assurance level.

There have been no significant changes that occurred during the quarter covered by this report in our internal control over financial reporting identified in connection with the evaluation referenced above that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
