EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended March 31, 2015 of Kilroy Realty Corporation and Kilroy Realty, L.P. Unless stated otherwise or the context otherwise requires, references to “Kilroy Realty Corporation” or the “Company,” “we,” “our,” and “us” mean Kilroy Realty Corporation, a Maryland corporation, and its controlled and consolidated subsidiaries, and references to “Kilroy Realty, L.P.” or the “Operating Partnership” mean Kilroy Realty, L.P., a Delaware limited partnership, and its controlled and consolidated subsidiaries.

The Company is a real estate investment trust, or REIT, and the general partner of the Operating Partnership. As of March 31, 2015, the Company owned an approximate 98.0% common general partnership interest in the Operating Partnership. The remaining approximate 2.0% 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 that are reflected in the disclosures in this Form 10-Q. We believe it is important to understand the differences between the Company and the Operating Partnership in the context of how the Company and the Operating Partnership operate as an interrelated, consolidated company. The Company is a REIT, the only material asset of which is the partnership interests it holds in the Operating Partnership. As a result, the Company generally does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing equity from time to time and guaranteeing certain debt of the Operating Partnership. The Company itself is not directly obligated under any indebtedness, but guarantees some of the debt of the Operating Partnership. The Operating Partnership owns substantially all of the assets of the Company either directly or through its subsidiaries, conducts the operations of the Company’s business and is structured as a limited partnership with no publicly traded equity. Except for net proceeds from equity issuances by the Company, which the Company generally contributes to the Operating Partnership in exchange for units of partnership interest, the Operating Partnership generates the capital required by the Company’s business through the Operating Partnership’s operations, by the Operating Partnership’s incurrence of indebtedness or through the issuance of units of partnership interest.

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, to the extent not held by the Company, 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., a Delaware limited partnership (the “Finance Partnership”). This noncontrolling interest represents the Company’s 1% indirect general partnership interest in the Finance Partnership, which is directly held by Kilroy Realty Finance, Inc., a wholly owned subsidiary of the Company. The differences between stockholders’ equity, partners’ capital and noncontrolling interests result from the differences in the equity issued by the Company and the Operating Partnership, and in the Operating Partnership’s noncontrolling interest in the Finance Partnership.

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

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

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

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

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

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

• consolidated financial statements;

• the following notes to the consolidated financial statements:

◦ Note 8, Stockholders’ Equity of the Company;

◦ Note 9, Partners’ Capital of the Operating Partnership;

i

◦ Note 13, Net Income Available to Common Stockholders Per Share of the Company; and

◦ Note 14, Net Income Available to Common Unitholders Per Unit of the Operating Partnership;

• “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

◦ —Liquidity and Capital Resources of the Company;” and

◦ —Liquidity and Capital Resources of the Operating Partnership.”

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

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Three Months Ended March 31, 2015 and 2014

1.    Organization and Basis of Presentation

Organization

Kilroy Realty Corporation (the “Company”) is a self-administered real estate investment trust (“REIT”) active in premier office submarkets along the West Coast. We own, develop, acquire and manage real estate assets, consisting primarily of Class A properties in the coastal regions of Los Angeles, Orange County, San Diego County, the San Francisco Bay Area and greater Seattle, which we believe have strategic advantages and strong barriers to entry. Class A real estate encompasses attractive and efficient buildings of high quality that are attractive to tenants, are well-designed and constructed with above-average material, workmanship and finishes and are well-maintained and managed. We qualify as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). The Company’s common stock is publicly traded on the New York Stock Exchange (“NYSE”) under the ticker symbol “KRC.”

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

Our stabilized portfolio of operating properties was comprised of the following office properties at March 31, 2015:

	Number of Buildings	Rentable Square Feet	Number of Tenants	Percentage  Occupied
Stabilized Office Properties	101	13,047,720	515	96.1	%

Our stabilized portfolio includes all of our properties with the exception of development and redevelopment properties currently under construction or committed for construction, “lease-up” properties, real estate assets held for sale and undeveloped land. We define redevelopment properties as those properties for which we expect to spend significant development and construction costs on the existing or acquired buildings pursuant to a formal plan, the intended result of which is a higher economic return on the property. As of March 31, 2015, we had no redevelopment properties. 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. There were no operating properties in “lease-up” as of March 31, 2015.

As of March 31, 2015, the following properties were excluded from our stabilized portfolio:

	Number of Properties/Projects	Estimated Rentable Square Feet
Properties held for sale (1)	10	1,044,844
Development projects under construction (2)	6	1,732,000

_______________

(1) Includes one property located in Redmond, Washington and nineproperties located in the Sorrento Mesa/UTC submarkets of San Diego, California. For additional information see Note 3.

(2) Estimated rentable square feet upon completion.

Our stabilized portfolio also excludes our future development pipeline, which is comprised of ten potential development sites, representing approximately 106 gross acres of undeveloped land.

As of March 31, 2015, all of our stabilized portfolio properties and development projects were owned and all of our business was conducted in the state of California with the exception of twelve office properties and a recently acquired development opportunity located in the state of Washington. All of our properties and development projects are 100% owned, excluding a development project owned by Redwood City Partners, LLC (“Redwood LLC”), a consolidated subsidiary (seeNote 1) and certain properties held at qualified intermediaries for potential future transactions that are intended to qualify as like-kind exchanges pursuant to Section 1031 of the Code (“Section 1031 Exchanges”) to defer taxable gains on dispositions for federal and state income tax purposes, which have been consolidated for financial reporting purposes.

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

As of March 31, 2015, the Company owned an approximate 98.0% common general partnership interest in the Operating Partnership. The remaining approximate 2.0% common limited partnership interest in the Operating Partnership as of March 31, 2015 was owned by non-affiliated investors and certain of our executive officers and directors (see Note 7). Both the general and limited common partnership interests in the Operating Partnership are denominated in common units. Generally, the number of common units held by the Company is equivalent to the number of outstanding shares of the Company’s common stock, and the rights of all the common units to quarterly distributions and payments in liquidation mirror those of the Company’s common stockholders. The common limited partners have certain redemption rights as provided in the Operating Partnership’s Seventh Amended and Restated Agreement of Limited Partnership, as amended, the “Partnership Agreement” (see Note 7).

Kilroy Realty Finance, Inc., which is a wholly owned subsidiary of the Company, is the sole general partner of the Finance Partnership and owns a 1.0% common general partnership interest in the Finance Partnership. The Operating Partnership owns the remaining 99.0% common limited partnership interest. Kilroy Services, LLC (“KSLLC”), which is a wholly owned subsidiary of the Operating Partnership, is the entity through which we generally conduct substantially all of our development activities. With the exception of the Operating Partnership and Redwood LLC, all of our 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, Redwood LLC and all of our wholly owned and controlled subsidiaries. The consolidated financial statements of the Operating Partnership include the consolidated financial position and results of operations of the Operating Partnership, the Finance Partnership, KSLLC, Redwood LLC and all wholly-owned and controlled subsidiaries of the Operating Partnership. All intercompany balances and transactions have been eliminated in the consolidated financial statements.

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, 2015. The interim financial statements for the Company and the Operating Partnership should be read in conjunction with the audited consolidated financial statements and notes thereto included in our annual report on Form 10-K for the year ended December 31, 2014.

Certain amounts in the consolidated statements of operations for prior periods have been reclassified to reflect the activity of discontinued operations disposed of prior to the Company's adoption of Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2014-08 (“ASU 2014-08”). Properties classified as held for sale and/or disposed of prior to January 1, 2015 are presented as discontinued operations for all periods presented.

Variable Interest Entities

At March 31, 2015, the consolidated financial statements of the Company and the Operating Partnership included two variable interest entities (“VIEs”), in which we were deemed to be the primary beneficiary. One VIE, Redwood LLC, was established in the second quarter of 2013 in connection with an undeveloped land acquisition. The other VIE was established during the first quarter of 2015 to facilitate potential future Section 1031 Exchanges to defer taxable gains on dispositions for federal and state income tax purposes. The impact of consolidating the VIEs increased the Company’s total assets, liabilities and noncontrolling interests by approximately $173.0 million (of which $171.1 million related to real estate held for investment on our consolidated balance sheet), approximately $16.5 million and approximately $5.9 million, respectively, as of March 31, 2015.

As of December 31, 2014, the consolidated financial statements of the Company and the Operating Partnership included two VIEs, in which we were deemed to be the primary beneficiary. One of the VIEs was Redwood LLC and the remaining VIE was established during the fourth quarter of 2014 to facilitate potential Section 1031 Exchanges. During the three months ended March 31, 2015, the Section 1031 Exchange was successfully completed and the VIE was terminated. As a result, $59.2 million of our restricted cash balance at December 31, 2014, which related to prior period disposition proceeds that were set aside to facilitate the Section 1031 Exchange, was released from escrow. The impact of consolidating the VIEs increased the Company’s total assets, liabilities and noncontrolling interests by approximately $219.6 million (of which $211.8 million related to real estate held for

12

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

investment on our consolidated balance sheet), approximately $23.4 million and approximately 5.9 million, respectively, as of December 31, 2014.

Adoption of New Accounting Pronouncements

Effective January 1, 2015, the Company adopted FASB ASU 2014-08, which changed the criteria for reporting discontinued operations while enhancing disclosures in this area. Under the new guidance, only disposals representing a strategic shift that has (or will have) a major effect on an entity's operations and final results, such as a major line of business, a major geographical area or a major equity investment, should be presented as discontinued operations. The Company adopted and applied the new guidance on a prospective basis as required by ASU 2014-08. Therefore, real estate assets classified as held for sale and/or disposed of subsequent to January 1, 2015 that do not represent a strategic shift will be presented in continuing operations for all periods presented. Properties classified as held for sale and/or disposed of prior to January 1, 2015 will continue to be presented in discontinued operations for prior periods presented. In accordance with this guidance, the operations of the ten properties held for sale at March 31, 2015 are presented in continuing operations for the three months ended March 31, 2015. For the three months ended March 31, 2014, discontinued operations includes the income and gains on all of the properties sold in 2014.

Recently Issued Accounting Pronouncements

On April 7, 2015 the FASB issued ASU No. 2015-03 (“ASU 2015-03”) to amend the accounting guidance for the presentation of debt issuance costs. The standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU 2015-03 is effective for public business entities for fiscal years beginning after December 15, 2015 and retrospective application is required. Early adoption of the guidance is permitted. The Company expects to adopt the guidance effective January 1, 2016 and the guidance is not anticipated to have a material impact on our consolidated financial statements or notes to our consolidated financial statements.

On April 1, 2015, the FASB voted to defer the effective date of ASU No. 2014-09, which outlines a single comprehensive model for entities to use in accounting for revenues arising from contracts with customers and notes that lease contracts with customers are a scope exception. Public business entities may elect to adopt the amendments as of the original effective date; however if the proposed deferral is approved, adoption is required for annual reporting periods beginning after December 15, 2017. The Company is currently assessing the impact of the guidance on our consolidated financial statements or notes to our consolidated financial statements.

On February 18, 2015 the FASB issued ASU No. 2015-02 (“ASU 2015-02”) to amend the accounting guidance for consolidation. The standard simplifies the current guidance for consolidation and reduces the number of consolidation models through the elimination of the indefinite deferral of Statement 167. Additionally, the standard places more emphasis on risk of loss when determining a controlling financial interest. ASU 2015-02 is effective for all entities for reporting periods (including interim periods) beginning after December 15, 2015, and early adoption is permitted. The Company expects to adopt the guidance effective January 1, 2016 and the guidance is not anticipated to have a material impact on our consolidated financial statements or notes to our consolidated financial statements.

7.    Noncontrolling Interests on the Company’s Consolidated Financial Statements

Common Units of the Operating Partnership

The Company owned an approximate 98.0%, 98.0% and 97.9% common general partnership interest in the Operating Partnership as of March 31, 2015, December 31, 2014 and March 31, 2014, respectively. The remaining approximate 2.0%, 2.0% and 2.1% common limited partnership interest as of March 31, 2015, December 31, 2014 and March 31, 2014, respectively, was owned by non-affiliate investors and certain of our executive officers and directors in the form of noncontrolling common units. There were 1,793,170, 1,804,200 and 1,804,200 common units outstanding held by these investors, executive officers and directors as of March 31, 2015, December 31, 2014 and March 31, 2014, respectively.

The noncontrolling common units may be redeemed by unitholders for cash. Except under certain circumstances, we, at our option, may satisfy the cash redemption obligation with shares of the Company’s common stock on a one-for-one basis. If satisfied in cash, the value for each noncontrolling common unit upon redemption is the amount equal to the average of the closing quoted price per share of the Company’s common stock, par value $.01 per share, as reported on the NYSE for the ten trading days immediately preceding the applicable redemption date. The aggregate value upon redemption of the then-outstanding noncontrolling common units was $137.9 millionand $126.8 million as of March 31, 2015 and December 31, 2014, respectively. This redemption value does not necessarily represent the amount that would be distributed with respect to each noncontrolling 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 liquidating distribution payable in respect of each share of the Company’s common stock.

At-The-Market Stock Offering Program

Under our current at-the-market stock offering program, which commenced in December 2014, we may offer and sell shares of our common stock having an aggregate gross sales price of up to $300.0 million from time to time in “at-the-market” offerings. Since commencement of the program through March 31, 2015, we have sold 1,648,893 shares of common stock having an aggregate gross sales price of $124.7 million. As of March 31, 2015, shares of common stock having an aggregate gross sales price of up to $175.3 million remain available to be sold under this program. Actual future sales will depend upon a variety of factors, including but not limited to market conditions, the trading price of the Company’s common stock and our capital needs. We have no obligation to sell the remaining shares available for sale under this program.

The following table sets forth information regarding sales of our common stock under our at-the-market offering program for the three months ended March 31, 2015:

10.    Share-Based Compensation

Stockholder Approved Equity Compensation Plans

As of March 31, 2015, we maintained one share-based incentive compensation plan, the Kilroy Realty 2006 Incentive Award Plan as amended (the “2006 Plan”). As of March 31, 2015, 494,405 shares were available for grant under the 2006 Plan. The calculation of shares available for grant includes a reserve for a sufficient number of shares to cover the vesting and payment of performance-based vesting awards at the target levels for either performance and/or market conditions with outstanding performance periods. At our Annual Meeting of Stockholders, currently scheduled to be held on May 21, 2015, stockholders will be asked to approve an amendment and restatement of the 2006 Plan, which includes an increase in the share limit by 1,200,000 shares so the new aggregate share limit for the 2006 Plan would be 8,320,000 shares.

2015 Share-Based Compensation Grants

On January 27, 2015, the Executive Compensation Committee of the Company’s Board of Directors awarded 212,468 restricted stock units (“RSUs”) to certain officers of the Company under the 2006 Plan, which included 127,657 RSUs, or 60%, that are

20

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

subject to market and performance-based vesting requirements (the “2015 Performance-Based RSUs”) and 84,811 RSUs, or 40%, that are subject to time-based vesting requirements (the “2015 Time-Based RSUs”).

2015 Performance-Based RSU Grant

The 2015 Performance-Based RSUs are scheduled to vest at the end of a three-year period based upon the achievement of pre-set FFO per share goals (the “performance condition”) for the year ending December 31, 2015 and also based upon the average annual relative total stockholder return targets (the “market condition”) for the three-year period ending December 31, 2017. The 2015 Performance-Based RSUs are also subject to a three-year service vesting provision and will cliff vest at the end of the three-year period. The number of 2015 Performance-Based RSUs ultimately earned, and therefore the compensation costs for these awards, could fluctuate from the 127,657 RSUs granted based upon the levels of achievement for both the FFO per share and relative stockholder return metrics. During the 2015 performance period, the estimate of the number of awards earned are evaluated quarterly based on our forecasted level of achievement of the FFO hurdle. Compensation expense for the 2015 Performance-Based RSU grant will be recorded on a straight-line basis over the three-year period.

Each 2015 Performance-Based RSU represents the right to receive one share of our common stock in the future. The total fair value of the 2015 Performance-Based RSU grant was $10.1 million at January 27, 2015 and was calculated using a Monte Carlo simulation pricing model based on the assumptions in the table below. The determination of the fair value of the 2015 Performance-Based RSU grant takes into consideration the likelihood of achievement of both the performance condition and the market condition discussed above. For the three months ended March 31, 2015, we recorded compensation expense based upon the $78.55 fair value at January 27, 2015. The following table summarizes the assumptions utilized in the Monte Carlo simulation pricing model:

	Fair Value Assumptions
Fair value per share at January 27, 2015	$78.55
Expected share price volatility	20.00%
Risk-free interest rate	0.92%
Remaining expected life	2.9 years

The computation of expected volatility is based on a blend of the historical volatility of our shares of common stock over approximately six years, as that is expected to be most consistent with future volatility and equates to a time period twice as long as the approximate three-year remaining performance period of the RSUs and implied volatility data based on the observed pricing of six month publicly-traded options on our shares of common stock. The risk-free interest rate is based on the yield curve on zero-coupon U.S. Treasury STRIP securities in effect at January 27, 2015. The expected dividend yield is estimated by examining the average of the historical dividend yield levels over the remaining 2.9 year term of the RSUs and our current annualized dividend yield as of January 27, 2015. The expected life of the RSUs is equal to the remaining 2.9 year vesting period at January 27, 2015.

2015 Time-Based RSU Grant

The 2015 Time-Based RSUs are scheduled to vest in three equal installments beginning on January 5, 2016 through January 5, 2018. Compensation expense for the 2015 Time-Based RSUs will be recognized on a straight-line basis over the three-year service vesting period. Each 2015 Time-Based RSU represents the right to receive one share of our common stock in the future. The total fair value of the 2015 Time-Based RSU grant was $6.4 million, which was based on the $75.34 closing share price of the Company’s common stock on the NYSE on January 27, 2015.

Share-Based Award Activity

During the three months ended March 31, 2015, 237,000 non-qualified stock options were exercised and issued at an exercise price per share equal to $42.61. As of March 31, 2015, we had 765,000 stock options outstanding.

Share-Based Compensation Cost Recorded During the Period

The total compensation cost for all share-based compensation programs was $4.3 million and $2.9 million for the three months ended March 31, 2015 and 2014, respectively. Of the total share-based compensation costs, $0.7 million and $0.4 million was capitalized as part of real estate assets for the three months ended March 31, 2015 and 2014, respectively. As of March 31, 2015, there was approximately $42.5 million of total unrecognized compensation cost related to nonvested incentive awards granted

21

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

under share-based compensation arrangements that is expected to be recognized over a weighted-average period of 2.5 years. The remaining compensation cost related to these nonvested incentive awards had been recognized in periods prior to March 31, 2015.

11.    Commitments and Contingencies

While there can be no assurance that a material environmental liability does not exist, we are not currently aware of any environmental liability with respect to our stabilized portfolio properties that would have a material adverse effect on our financial condition, results of operations and cash flow, or that we believe would require additional disclosure or the recording of a loss contingency.

As of March 31, 2015, we had accrued environmental remediation liabilities of approximately $16.1 million recorded on our consolidated balance sheets in connection with certain of our recent development acquisitions and related development activities. It is possible that we could incur additional environmental remediation costs in connection with these recent development acquisitions.  However, given we are in the very early stages of development, possible additional environmental costs are not reasonably estimable at this time. 

12.    Fair Value Measurements and Disclosures

Assets and Liabilities Reported at Fair Value

The only assets we record at fair value on our consolidated financial statements are the marketable securities related to our Deferred Compensation Plan. The following table sets forth the fair value of our marketable securities as of March 31, 2015 and December 31, 2014:

	Fair Value (Level  1) (1)
	March 31, 2015		December 31, 2014
Description	(in thousands)
Marketable securities (2)	$	13,337	$	11,971

_______________

(1) Based on quoted prices in active markets for identical securities.

(2) The marketable securities are held in a limited rabbi trust.

We report the change in the fair value of the marketable securities at the end of each accounting period in interest income and other net investment gains in the consolidated statements of operations. We also adjust the related Deferred Compensation Plan liability to fair value at the end of each accounting period based on the performance of the benchmark funds selected by each participant, which results in a corresponding increase or decrease to compensation cost for the period.

The following table sets forth the net gain on marketable securities recorded during the three months ended March 31, 2015 and 2014:

(1) Participating securities include nonvested shares, certain time-based RSUs and vested market measure-based RSUs.

(2) The Company adopted ASU 2014-08 effective January 1, 2015 (see Note 1). As a result, properties classified as held for sale and/or disposed of subsequent to January 1, 2015 that do not represent a strategic shift are no longer presented as discontinued operations.

The impact of the contingently issuable shares were considered in our diluted earnings per share calculation for the three months ended March 31, 2015 and 2014, because we reported income from continuing operations attributable to common stockholders in the respective periods and the effect was dilutive. As of March 31, 2015 contingently issuable shares consist of stock options and 182,610 market measure-based RSUs. As of March 31, 2014 contingently issuable shares consist of stock options and the impact of the Company's 4.25% Exchangeable Notes due November 2014 (the "4.25% Exchangeable Notes") prior to their maturity and settlement in November 2014. As of March 31, 2014 the 182,610 market measure-based RSUs were not included in dilutive securities since they were considered contingently issuable shares as not all the necessary performance conditions had been met. The 2015 Performance-Based RSUs and our other nonvested market measure-based RSUs are not included in dilutive securities as of March 31, 2015 and 2014 because they are not included until all the necessary performance conditions have been met.

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

OPERATIONS

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

Forward-Looking Statements

Statements contained in this “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” that are not historical facts may be forward-looking statements. Forward-looking statements include, among other things, statements or information concerning projected future occupancy and rental rates, lease expirations, debt maturity, potential investments, strategies such as capital recycling, development and redevelopment activity, projected construction costs, dispositions, future incentive compensation, pending, potential or proposed acquisitions and other forward-looking financial data, as well as the discussion below under the captions “—Factors That May Influence Future Results of Operations,” “—Liquidity and Capital Resource of the Company,” and “—Liquidity and Capital Resources of the Operating Partnership.” Forward-looking statements can be identified by the use of words such as “believes,” “expects,” “projects,” “may,” “will,” “should,” “targets,” “seeks,” “approximately,” “intends,” “plans,” “pro forma,” “estimates” or “anticipates” and the negative of these words and phrases and similar expressions that do not relate to historical matters. Forward-looking statements are based on our current expectations, beliefs and assumptions, and are not guarantees of future performance. Forward-looking statements are inherently subject to uncertainties, risks, changes in circumstances, trends and factors that are difficult to predict, many of which are outside of our control. Accordingly, actual performance, results and events may vary materially from those indicated in the forward-looking statements, and you should not rely on the forward-looking statements as predictions of future performance, results or events. Numerous factors could cause actual future performance, results and events to differ materially from those indicated in forward-looking statements. For a discussion of those risk factors, see the discussion below as well as “Item 1A. Risk Factors” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s and the Operating Partnership’s annual report on Form 10-K for the year ended December 31, 2014 and their respective other filings with the SEC. All forward-looking statements are based on information that was available and speak only as of the date on which they are made. We assume no obligation to update any forward-looking statement that becomes untrue because of subsequent events, new information or otherwise, except to the extent we are required to do so in connection with our ongoing requirements under Federal securities laws.

Overview and Background

We are a self-administered REIT active in premier office submarkets along the West Coast. We own, develop, acquire and manage real estate assets, consisting primarily of Class A properties in the coastal regions of Los Angeles, Orange County, San Diego County, the San Francisco Bay Area and greater Seattle, which we believe have strategic advantages and strong barriers to entry. We own our interests in all of our properties through the Operating Partnership and the Finance Partnership and generally conduct substantially all of our operations through the Operating Partnership. We owned an approximate 98.0%, 98.0% and 97.9% general partnership interest in the Operating Partnership as of March 31, 2015, December 31, 2014 and March 31, 2014, respectively. All of our properties are held in fee except for the eleven office buildings that are held subject to long-term ground leases for the land.

Factors That May Influence Future Results of Operations

In-Process and Future Development Pipeline. We believe that a significant portion of our long-term future growth will come from the completion of our under construction and in-process development projects as well as executing on our future development pipeline, including expanding entitlements, subject to market conditions. Over the past two years, we increased our focus on development opportunities and expanded our future development pipeline through targeted acquisitions of development opportunities on the West Coast.

We have a proactive planning process by which we continually evaluate the size, timing, costs and scope of our development program and, as necessary, scale activity to reflect the economic conditions and the real estate fundamentals that exist in our submarkets. We expect to execute on our development program with prudence and will be pursuing opportunities with attractive economic returns in strategic locations with proximity to public transportation or transportation access and retail amenities and in markets with strong fundamentals and visible demand. We plan to develop in phases as appropriate and we strongly favor starting projects that are pre-leased.

27

As of March 31, 2015, our in-process development pipeline consisted of the following six projects under construction, which was 85% pre-leased at March 31, 2015.

• 350 Mission Street, SOMA, San Francisco, California, which we acquired in October 2012. This development project, which is 100% pre-leased to salesforce.com, Inc., has a total estimated investment of approximately $280 million and will encompass approximately 450,000 rentable square feet upon completion. The property is expected to be LEED platinum certified, the first ground up high-rise development property in the city expected to receive this designation. Construction is currently in process and is expected to be completed towards the end of 2015, and the tenant is currently expected to occupy in phases.

• 333 Brannan Street, SOMA, San Francisco, California, which we acquired in July 2012. This development project is 100% pre-leased to Dropbox, has a total estimated investment of approximately $105 million and will encompass 185,000 rentable square feet upon completion. The property is expected to be LEED platinum certified and construction is currently in process and is expected to be completed at the end of the fourth quarter in 2015.

• Crossing/900, Redwood City, California, which we acquired in June 2013 with a local partner. This development project is 100% pre-leased to Box, Inc., has a total estimated investment of approximately $190 million and will encompass approximately 339,000 rentable square feet upon completion. Construction is currently in process and the first of two office buildings will be delivered early in the fourth quarter of 2015.

• Columbia Square, Hollywood, California, which we acquired in September 2012. This development project is comprised of two phases, historical and new office and residential, and is located in the heart of Hollywood, California, two blocks from the corner of Sunset Boulevard and Vine Street. During 2013, we commenced development on both phases comprising approximately 685,000 rentable square feet. The two office components comprising 480,000 square feet have an estimated investment of approximately $300 million and are expected to be completed in phases between the second quarter of 2015 and the first quarter of 2016, and the project is expected to be stabilized in phases between the second quarter of 2015 and the first quarter of 2017.

The second phase, the residential component of the project, which will encompass approximately 205,000 square feet upon completion, will be a mix of high-end long-term rentals and extended stay apartment homes and has an estimated investment of approximately $140 million. It will be the first luxury extended stay property to be located in the heart of Hollywood. Construction of this project is currently expected to be completed in the first quarter of 2016 and the project is expected to be stabilized in phases through the first quarter of 2017.

• The Heights at Del Mar, Del Mar, California, which we acquired in September 2013. The project is a 73,000 square foot office project and has a total estimated investment of approximately $45 million. Construction on this project is currently in process and is expected to be completed in the fourth quarter of 2015.

In addition, as of March 31, 2015, we had additional undeveloped land holdings, located in various submarkets in San Diego County, San Francisco Bay Area, Greater Seattle and Los Angeles with an aggregate cost basis of approximately $598.0 million at which we believe we could develop more than 3.0 million rentable square feet, depending on successful obtainment of entitlements and market conditions. In the future, we may also enter into agreements to acquire other development or redevelopment opportunities, either as wholly owned properties or through joint ventures, and those agreements typically will be subject to the satisfaction of closing conditions.

Increase in our development activities could continue to cause an increase in the average development asset balances qualifying for interest and other carry cost capitalization in future periods. For the three months ended March 31, 2015 and 2014, we capitalized $10.9 million and $10.8 million, respectively, of interest to our qualifying development projects. For the three months ended March 31, 2015 and 2014, we capitalized $3.5 million and $2.6 million, respectively, of internal costs to our qualifying redevelopment and development projects.

Development Acquisitions. During the three months ended March 31, 2015, we acquired one future development opportunity in Greater Seattle for a purchase price of $49.5 million. During 2014, we acquired five office buildings in two transactions for an aggregate purchase price of approximately $206.6 million and three undeveloped land sites, including two adjacent land sites, in three transactions with an aggregate purchase price of approximately $166.0 million. We generally finance our acquisitions through proceeds from the issuance of debt and equity securities, borrowings under our unsecured revolving credit facility, proceeds from our capital recycling program, the assumption of existing debt and cash flows from operations.

28

As a key component of our growth strategy, we continue to evaluate value-add acquisition opportunities (including undeveloped land, development opportunities and operating properties). As a result, at any point in time we may have one or more potential acquisitions under consideration that are in varying stages of evaluation, negotiation or due diligence review, which may include potential acquisitions under contract. We remain a disciplined buyer of development opportunities and operating properties and continue to focus on value-add opportunities in West Coast markets populated by knowledge and creative based tenants in a variety of industries, including technology, media, healthcare, entertainment and professional services. We cannot provide assurance that we will complete additional future acquisitions. In the future, we may enter into agreements to acquire additional properties or undeveloped land, either as wholly owned properties or through joint ventures, and those agreements typically will be subject to the satisfaction of closing conditions. We cannot provide assurance that we will enter into any agreements to acquire properties, or undeveloped land, or that the potential acquisitions contemplated by any agreements we may enter into in the future will be completed.

Costs associated with acquisitions accounted for as business combinations are expensed as incurred, and we may be unable to complete an acquisition after making a nonrefundable deposit or incurring acquisition-related costs. In addition, acquisitions are subject to various other risks and uncertainties. We expect that during the remainder of 2015 we will continue to pursue value-add property and undeveloped land acquisitions that we expect to either add immediate Net Operating Income to our portfolio or play a strategic role in our future growth.

Capital Recycling Program. We continuously evaluate opportunities for the potential disposition of properties and undeveloped land in our portfolio. See the “Liquidity and Capital Resources of the Operating Partnership – Liquidity Sources” section for further information regarding our capital recycling strategy.

In connection with our capital recycling strategy, during the three months ended March 31, 2015, we completed the sale of one land parcel in Irvine, California to an unaffiliated third party for gross sales proceeds of $26.0 million. This land parcel was classified as held for sale as of December 31, 2014. In addition, as of March 31, 2015, we classified ten properties as held for sale that are located in Redmond, Washington and in San Diego, California. Four of these properties were sold in April 2015 and the remaining six properties are expected to be sold in the second quarter of 2015 for aggregate total gross proceeds of approximately $309.2 million. During 2014, we completed the sale of 17 properties and one undeveloped land parcel to unaffiliated third parties in six separate transactions for gross sales proceeds totaling approximately $432.6 million.

The timing of any potential future disposition transactions will depend on market conditions and other factors, including but not limited to, our capital needs and our ability to defer some or all of the taxable gains on the sales. We cannot assure you that we will dispose of any additional properties or that any acquisitions and/or dispositions will qualify as Section 1031 Exchanges. See the “Liquidity and Capital Resources of the Operating Partnership – Liquidity Sources” section for further information.

Leasing Activity and Changes in Rental Rates. The amount of net rental income generated by our properties depends principally on our ability to maintain the occupancy rates of currently leased space and to lease currently available space, newly developed or redeveloped properties, newly acquired properties with vacant space, and space available from unscheduled lease terminations. The amount of rental income we generate also depends on our ability to maintain or increase rental rates in our submarkets. Negative trends in one or more of these factors could adversely affect our rental income in future periods. The following tables set forth certain information regarding leasing activity for our stabilized portfolio during the three months ended March 31, 2015.

_______________________

(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 or signed during the period, including first and second generation space, net of month-to-month leases. Excludes leasing on new construction.

(3) Tenant improvements and leasing commissions per square foot exclude tenant-funded tenant improvements.

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

(5) Excludes commenced and executed leases of approximately 122,538 square feet for the three months ended March 31, 2015 and 41,465 rentable square feet for the threemonths ended March 31, 2015, for which the space was vacant longer than one year or being leased for the first time. Space vacant for more than one year is excluded from our change in rents calculations to provide a meaningful market comparison.

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

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

(8) For the three months ended March 31, 2015, 16 new leases totaling 152,489 rentable square feet were signed but not commenced as of March 31, 2015.

As of March 31, 2015, we believe that the weighted average cash rental rates for our stabilized portfolio, including recently acquired operating properties, are approximately 10% under the current average market rental rates, although individual properties within any particular submarket presently may be leased either above, below, or at the current market rates within that submarket, and the average rental rates for individual submarkets may be above, below, or at the average cash rental rate of our portfolio.

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

(1) The information presented for all lease expiration activity reflects leasing activity through March 31, 2015 for our stabilized portfolio. 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, intercompany leases, vacant space and lease renewal options not executed as of March 31, 2015.

(2) Annualized base rent includes the impact of straight-lining rent escalations and the amortization of free rent periods and excludes the impact of the following: amortization of deferred revenue related tenant-funded tenant improvements, amortization of above/below market rents, amortization for lease incentives due under existing leases and expense reimbursement revenue. Additionally, the underlying leases contain various expense structures including full service gross, modified gross and triple net. Percentages represent percentage of total portfolio annualized contractual base rental revenue. For additional information on tenant improvement and leasing commission costs incurred by the Company for the current reporting period, please see further discussion under the caption “Information on Leases Commenced and Executed.”

In addition to the 0.5 million rentable square feet, or 3.9%, of currently available space in our stabilized portfolio, leases representing approximately 7.1% and 6.7% of the occupied square footage of our stabilized portfolio are scheduled to expire during 2015 and 2016, respectively. The leases scheduled to expire during the remainder of 2015 and in 2016 represent approximately 1.7 million rentable square feet or 11.5% of our total annualized base rental revenue. We believe that the weighted average cash rental rates are approximately 10% under the current average market rental rates for leases scheduled to expire during the remainder of 2015 and in 2016, although individual properties within any particular submarket presently may be leased either above, below, or at the current quoted market rates within that submarket, and the average rental rates for individual submarkets may be above, below, or at the average cash rental rate of our overall portfolio. Our ability to re-lease available space depends upon both general market conditions and the market conditions in the specific regions in which individual properties are located.

Incentive Compensation. Our Executive Compensation Committee determines compensation, including cash bonuses and equity incentives, for our executive officers. For 2015, the annual cash bonus program was structured to allow the Executive Compensation Committee to evaluate a variety of key quantitative and qualitative metrics at the end of the year and make a determination based on the Company’s and management’s overall performance. Our Executive Compensation Committee also grants equity incentive awards from time to time that include performance-based or market-measure based vesting requirements and/or time-based vesting requirements. As a result, accrued incentive compensation and compensation expense for future awards may be affected by our operating and development performance, financial results, stock price, performance against applicable performance-based vesting goals, market conditions and other factors. Consequently, we cannot predict the amounts that will be recorded in future periods related to such incentive compensation.

As of March 31, 2015, there was approximately $42.5 million of total unrecognized compensation cost related to outstanding nonvested shares of restricted common stock, RSUs and stock options issued under share-based compensation arrangements. Those costs are expected to be recognized over a weighted-average period of 2.5 years. The $42.5 million of unrecognized compensation cost does not reflect the future compensation cost for any potential share-based awards that may be issued. Share-based compensation expense for potential future awards could be affected by our operating and development performance, financial results, stock price, performance against applicable performance-based vesting goals, market conditions and other factors.

Stabilized Portfolio Information

As of March 31, 2015, our stabilized portfolio was comprised of 101 office properties encompassing an aggregate of approximately 13.0 million rentable square feet. Our stabilized portfolio includes all of our properties with the exception of development and redevelopment properties currently under construction or committed for construction, “lease-up” properties, real estate assets held for sale and undeveloped land. We define redevelopment properties as those properties for which we expect to spend significant development and construction costs on the existing or acquired buildings pursuant to a formal plan, the intended

31

result of which is a higher economic return on the property. We had no redevelopment properties as of March 31, 2015. 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. There were no operating properties in “lease-up” as of March 31, 2015. Our stabilized portfolio also excludes our future development pipeline, which is comprised of ten potential development sites, representing approximately 106 gross acres of undeveloped land on which we believe we have the potential to develop over 3.0 million square feet of office space, depending upon economic conditions.

As of March 31, 2015, the following properties were excluded from our stabilized portfolio:

	Number of Properties/Projects	Estimated Rentable Square Feet
Properties held for sale (1)	10	1,044,844
Development projects under construction (2)	6	1,732,000

Current Regional Information

The West Coast real estate markets in which we operate continue to strengthen, driven by improving economic conditions, net positive job growth and rising business confidence and expansion, especially among the region's technology, social media, entertainment, life science and communication industries.

San Francisco Bay Area. In the first quarter of 2015, the San Francisco Bay Area market continued to outperform most U.S. real estate markets and continues to be led by the strength in the technology sector. Rental growth remains strong as supply of large blocks of space remains limited. As of March 31, 2015, our San Francisco Bay Area stabilized portfolio of 3.9 million rentable square feet was 97.3% occupied with approximately 105,000 available rentable square feet, compared to 97.3% occupied with approximately 104,000 available rentable square feet as of December 31, 2014. As of March 31, 2015, we were 99.2% leased in the San Francisco Bay Area.

As of March 31, 2015, leases representing an aggregate of approximately 162,000 and 118,000 rentable square feet are scheduled to expire during the remainder of 2015 and in 2016, respectively, in this region. The aggregate rentable square feet under leases scheduled to expire during the remainder of 2015 and in 2016 represents approximately 2.3% of our occupied rentable square feet and 2.6% of our annualized base rental revenues in our total stabilized portfolio as of March 31, 2015.

Greater Seattle. During the first quarter of 2015, Greater Seattle experienced strong leasing activity. As of March 31, 2015, our greater Seattle stabilized portfolio of 2.1 million rentable square feet was 97.5% occupied with approximately 51,000 available rentable square feet, compared to 98.1% occupied with approximately 43,000 available rentable square feet as of December 31, 2014. As of March 31, 2015, we were 98.4% leased in the Greater Seattle Area.

As of March 31, 2015, leases representing an aggregate of approximately 171,000 and 98,000 rentable square feet are scheduled to expire during the remainder of 2015 and in 2016, respectively, in this region. The aggregate rentable square feet under leases scheduled to expire during the remainder of 2015 and in 2016 represents approximately 2.2% of our occupied rentable square feet and 1.5% of our annualized base rental revenues in our total stabilized portfolio as of March 31, 2015.

San Diego County. San Diego continued to show signs of growth during the first quarter of 2015 driven by the diversification of its economy, including scientific research and development, tourism, defense and professional services. Our San Diego County stabilized portfolio of 3.3 million rentable square feet was 95.8% occupied with approximately 138,000 available rentable square feet as of March 31, 2015 compared to 90.9% occupied with approximately 386,000 available rentable square feet as of December 31, 2014. The increase in occupancy is primarily due to the exclusion of the held for sale properties from our stabilized portfolio at March 31, 2015. As of March 31, 2015, we were 96.8% leased in San Diego County.

As of March 31, 2015, leases representing an aggregate of approximately 279,000 and 292,000 rentable square feet are scheduled to expire during the remainder of 2015 and in 2016, respectively, in this region. The aggregate rentable square feet under leases scheduled to expire during the remainder of 2015 and in 2016 represents approximately 4.7% of our occupied rentable square feet and 3.3% of our annualized base rental revenues in our total stabilized portfolio as of March 31, 2015.

Los Angeles and Ventura Counties. During the first quarter of 2015, the Los Angeles market continued to strengthen driven by the creative industries of technology and entertainment, which are seeing the largest rental increases. Our Los Angeles and Ventura Counties stabilized portfolio of 3.5 million rentable square feet was 94.3% occupied with approximately 200,000 available rentable square feet as of March 31, 2015 compared to 92.8% occupied with approximately 252,000 available rentable square feet as of December 31, 2014. The increase in occupancy is primarily due to the commencement of one new lease encompassing 77,000 square feet. Across our Los Angeles portfolio, as of March 31, 2015, we were 95.4% leased.

As of March 31, 2015, leases representing an aggregate of approximately 236,000 and 282,000 rentable square feet are scheduled to expire during the remainder of 2015 and in 2016, respectively, in this region. The aggregate rentable square feet under the leases scheduled to expire in this region during the remainder of 2015 and in 2016 represents approximately 4.3% of our occupied rentable square feet and 3.8% of our annualized base rental revenues in our total stabilized portfolio as of March 31, 2015.

Results of Operations

Net Operating Income

Management internally evaluates the operating performance and financial results of our stabilized portfolio based on Net Operating Income from continuing operations. 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). As a result of the Company’s adoption of the new discontinued operations accounting guidance (see Note 1 to our consolidated financial statements included in this report for additional information), for the quarter ended March 31, 2015 Net Operating Income from continuing operations includes the Net Operating Income for the ten properties held for sale at March 31, 2015. For the quarter ended March 31, 2014, Net Operating income from continuing operations does not include the Net Operating Income for properties held for sale or disposed of in prior years because properties classified as held for sale and/or disposed of prior to January 1, 2015 will continue to be presented in discontinued operations for prior periods presented.

Net Operating Income from continuing operations is considered by management to be an important and appropriate supplemental performance measure to net income (loss) because we believe it helps both investors and management to understand the core operations of our properties excluding corporate and financing-related costs and noncash depreciation and amortization. Net Operating Income is an unlevered operating performance metric of our properties and allows for a useful comparison of the operating performance of individual assets or groups of assets. This measure thereby provides an operating perspective not immediately apparent from GAAP income (loss) from operations or net income (loss). In addition, Net Operating Income is considered by many in the real estate industry to be a useful starting point for determining the value of a real estate asset or group of assets. Other real estate companies may use different methodologies for calculating Net Operating Income, and accordingly, our presentation of Net Operating Income may not be comparable to other real estate companies. Because of the exclusion of the items shown in the reconciliation below, Net Operating Income should only be used as a supplemental measure of our financial performance and not as an alternative to GAAP income (loss) from operations or net income (loss).

Management further evaluates Net Operating Income by evaluating the performance from the following property groups:

• Same Store Properties – which includes the results of all of the office properties that were owned and included in our stabilized portfolio for two comparable reporting periods, i.e., owned and included in our stabilized portfolio as of January 1, 2014 and still owned and included in the stabilized portfolio as of March 31, 2015;

• Stabilized Development and Redevelopment Properties – which includes the results generated by the following:

◦ One development project comprising three office buildings that was completed and stabilized in the third quarter of 2014;

◦ One development project consisting of two office buildings that was completed and stabilized in the fourth quarter of 2014;

◦ One redevelopment property that was stabilized in 2014 following its one year lease-up period; and

• Acquisition Properties – which includes the results, from the dates of acquisition through the periods presented, for the five office buildings we acquired during 2014;

• Held for Sale, Disposition and Other Properties – which includes the results for both periods presented of ten properties held for sale at March 31, 2015 and expenses for certain of our in-process and future development projects.

The following table sets forth certain information regarding the property groups within our stabilized portfolio as of March 31, 2015:

Group	# of Buildings	Rentable Square Feet
Same Store Properties	90	11,281,795
Stabilized Development and Redevelopment Properties	6	1,358,338
Acquisition Properties	5	407,587
Total Stabilized Portfolio (1)	101	13,047,720

_______________

(1) The stabilized portfolio excludes ten properties held for sale that encompass 1,044,844 rentable square feet at March 31, 2015.

Net Operating Income increased $20.1 million, or 23.0%, for the three months ended March 31, 2015 as compared to the three months ended March 31, 2014 primarily resulting from:

• An increase of $5.0 million attributable to the Same Store Properties primarily resulting from:

• An increase in rental income of $5.2 million, of which $3.4 million is due to new leases at higher rates primarily in the San Francisco Bay Area and Greater Seattle regions and $1.4 million is due to an increase in occupancy primarily in the Los Angeles and San Diego regions;

• An increase in tenant reimbursements of $0.3 million primarily due to an increase in recurring property operating expenses;

36

• A partially offsetting decrease in other property income of $1.4 million primarily due to $1.8 million of lease termination fees recognized mainly from one tenant during the three months ended March 31, 2014 as compared with $0.4 million of other property income during the three months ended March 31, 2015;

• A decrease in property and related expenses of $0.8 million primarily resulting from a decrease of $1.0 million in property expenses due to the following:

◦ $1.0 million decrease in non-recurring legal fees;

◦ $0.6 million insurance reimbursement received in 2015, offset by;

◦ $0.6 million increase to contract services, repairs and maintenance, and various other reimbursable expenses;

• An increase of $11.9 million attributable to the Stabilized Development and Redevelopment Properties primarily attributable to the properties completed and/or stabilized in September and October of 2014; and

• An increase of $3.4 million attributable to the Acquisition Properties.

Other Expenses and Income

General and Administrative Expenses

General and administrative expenses increased by approximately $2.0 million, or 18.1%, for the three months ended March 31, 2015 compared to the three months ended March 31, 2014. The increase was primarily attributable to an increase in payroll and administrative costs due to increased headcount related to the growth of the Company and an increase in share-based compensation costs as a result of the change in amortization method associated with our 2014 and 2015 share-based compensation grants.

Depreciation and Amortization

Depreciation and amortization increased by approximately $3.0 million, or 6.1%, for the three months ended March 31, 2015 compared to the three months ended March 31, 2014, primarily related to increases in the Stabilized Development and Redevelopment Properties of $3.4 million and the Acquisition Properties of $1.4 million, partially offset by a decrease in the Same Store Properties of $1.6 million.

Interest Expense

The following table sets forth our gross interest expense, including debt discounts/premiums and loan cost amortization, net of capitalized interest, including capitalized debt discounts/premiums and loan cost amortization for the three months ended March 31, 2015 and 2014:

Liquidity and Capital Resources of the Company

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

The Company’s business is operated primarily through the Operating Partnership. Distributions from the Operating Partnership are the Company’s primary source of capital. The Company believes the Operating Partnership’s sources of working capital, specifically its cash flow from operations and borrowings available under its unsecured revolving credit facility, are adequate for it to make its distribution payments to the Company and, in turn, for the Company to make its dividend payments to its preferred and common stockholders for the next twelve months. Cash flows from operating activities generated by the Operating Partnership for the three months ended March 31, 2015 were sufficient to cover the Company’s payment of cash dividends to its stockholders.However, there can be no assurance that the Operating Partnership’s sources of capital will continue to be available at all or in amounts sufficient to meet its needs, including its ability to make distributions to the Company. The unavailability of capital could adversely affect the Operating Partnership’s ability to make distributions to the Company, which would in turn, adversely affect the Company’s ability to pay cash dividends to its stockholders.

The Company is a well-known seasoned issuer and the Company and the Operating Partnership have an effective shelf registration statement that provides for the public offering and sale from time to time by the Company of its preferred stock, common stock, depositary shares, warrants and guarantees of debt securities and by the Operating Partnership of its debt securities, in each case in unlimited amounts. The Company evaluates the capital markets on an ongoing basis for opportunities to raise capital, and, as circumstances warrant, the Company and the Operating Partnership may issue securities of all of these types in one or more offerings at any time and from time to time on an opportunistic basis, depending upon, among other things, market conditions, available pricing and capital needs. When the Company receives proceeds from the sales of its preferred or common stock, it generally contributes the net proceeds from those sales to the Operating Partnership in exchange for corresponding preferred or common partnership units of the Operating Partnership. The Operating Partnership may use these proceeds and proceeds from the sale of its debt securities to repay debt, including borrowings under its unsecured revolving credit facility, to develop new or existing properties, to make acquisitions of properties or portfolios of properties, or for general corporate purposes.

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

Distribution Requirements

The Company is required to distribute 90% of its taxable income (subject to certain adjustments and excluding net capital gain) on an annual basis to maintain qualification as a REIT for federal income tax purposes and is required to pay income tax at regular corporate rates to the extent it distributes less than 100% of its taxable income (including capital gains). As a result of these distribution requirements, the Operating Partnership cannot rely on retained earnings to fund its on-going operations to the same extent as other companies whose parent companies are not REITs. In addition, the Company may be required to use borrowings under the Operating Partnership’s revolving credit facility, if necessary, to meet REIT distribution requirements and maintain its REIT status. The Company may also need to continue to raise capital in the equity markets to fund the Operating Partnership’s working capital needs, as well as potential developments of new or existing properties or acquisitions.

The Company intends to continue to make, but has not committed to make, regular quarterly cash distributions to common stockholders, and through the Operating Partnership, common unitholders from the Operating Partnership's cash flow from operating activities. All such distributions are at the discretion of the board of directors. The Company has historically distributed amounts in excess of its taxable income resulting in a return of capital to its stockholders and the Company currently believes it has the ability to maintain distributions at the 2015 levels to meet the REIT distribution requirements for 2015, before the impact of gains on real estate asset dispositions. However, there can be no assurance that the Company will have the ability to do so. In addition, to the extent that the Company cannot successfully complete Section 1031 Exchanges or enter into Section 1031 Exchanges to defer some or all of the taxable gains related to completed or future property dispositions, the Company may elect to distribute a special dividend to avoid having to pay income taxes on such gains. The Company considers market factors and its performance in addition to REIT requirements in determining its distribution levels. Amounts accumulated for distribution to stockholders are invested primarily in interest-bearing accounts and short-term interest-bearing securities, which are consistent with the Company’s

38

intention to maintain its qualification as a REIT. Such investments may include, for example, obligations of the Government National Mortgage Association, other governmental agency securities, certificates of deposit and interest-bearing bank deposits.

On February 24, 2015, the Board of Directors declared a regular quarterly cash dividend of $0.35 per share of common stock payable on April 15, 2015 to stockholders of record on March 31, 2015 and caused a $0.35 per Operating Partnership unit cash distribution to be paid in respect of the Operating Partnership’s common limited partnership interests, including those owned by the Company. The total cash quarterly dividends and distributions paid on April 15, 2015 was$31.4 million.

On February 24, 2015, the Board of Directors declared a dividend of $0.42969 per share on the Series G Preferred Stock and $0.39844 per share on the Series H Preferred Stock for the period commencing on and including February 16, 2015 and ending on and including May 14, 2015. The dividend will be payable on May 15, 2015 to Series G Preferred and Series H Preferred stockholders of record on April 30, 2015. The quarterly dividends payable on May 15, 2015 to Series G and Series H Preferred stockholders is expected to total $3.3 million.

Debt Covenants

The covenants contained within the unsecured revolving credit facility, unsecured term loan facility and unsecured term loan generally prohibit the Company from paying dividends in excess of 95% of FFO.

Capitalization

As of March 31, 2015, our total debt as a percentage of total market capitalization was 25.6% and our total debt and liquidation value of our preferred equity as a percentage of total market capitalization was 27.8%, which was calculated based on the closing price per share of the Company’s common stock of $76.17 on March 31, 2015 as shown in the following table:

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 Operating Partnership’s unsecured revolving credit facility and term loan 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 assets through our capital recycling program.

Liquidity Uses

• Development and redevelopment costs;

• Property or undeveloped land acquisitions;

• Property operating and corporate expenses;

• Capital expenditures, tenant improvement and leasing costs;

• Debt service and principal payments, including debt maturities;

• Distributions to common and preferred security holders; and

• Outstanding debt repurchases.

General Strategy

Our general strategy is to maintain a conservative balance sheet with a strong credit profile and to maintain a capital structure that allows for financial flexibility and diversification of capital resources. We manage our capital structure to reflect a long-term investment approach and utilize multiple sources of capital to meet our long-term capital requirements. We believe that our current projected liquidity requirements for the next twelve-month period, as set forth above under the caption “—Liquidity Uses,” will be satisfied using a combination of the liquidity sources listed above, although there can be no assurance in this regard. We believe our conservative leverage and staggered debt maturities provide us with financial flexibility and enhances our ability to obtain additional sources of liquidity if necessary, and, therefore, we are well-positioned to refinance or repay maturing debt and to pursue our strategy of seeking attractive acquisition opportunities, which we may finance, as necessary, with future public and private issuances of debt and equity securities.

Liquidity Sources

Unsecured Revolving Credit Facility

The following table summarizes the balance and terms of our unsecured revolving credit facility as of March 31, 2015 and December 31, 2014:

	March 31, 2015			December 31, 2014
	(in thousands)
Outstanding borrowings	$	130,000		$	140,000
Remaining borrowing capacity	470,000			460,000
Total borrowing capacity (1)(2)	$	600,000		$	600,000
Interest rate (2)	1.43		%	1.41		%
Facility fee-annual rate (3)	0.250%
Maturity date (2)	July 2019

_______________

(1) We may elect to borrow, subject to bank approval and obtaining commitments for any additional borrowing capacity, up to an additional $311.0 million under an accordion feature under the terms of the unsecured revolving credit facility and unsecured term loan facility.

(2) Our unsecured revolving credit facility interest rate was calculated based on an annual rate of LIBOR plus 1.250% as of March 31, 2015 and December 31, 2014.

(3) Our facility fee is paid on a quarterly basis and is calculated based on the total borrowing capacity. In addition to the facility fee, we incurred debt origination and legal costs. As of March 31, 2015, $5.6 million of deferred financing costs remains to be amortized through the maturity date of our unsecured revolving credit facility.

We intend to borrow under the unsecured revolving credit facility from time to time for general corporate purposes, to fund potential acquisitions, to finance development and redevelopment expenditures and to potentially repay long-term debt.

Capital Recycling Program

In connection with our capital recycling program, we continuously evaluate opportunities for the potential disposition of properties and undeveloped land in our portfolio with the intent of recycling the proceeds generated from the disposition of less strategic or lower return assets into capital used to finance development expenditures, to fund new acquisitions, to repay long-term debt and for other general corporate purposes. As part of this strategy, we attempt to enter into Section 1031 Exchanges, when possible, to defer some or all of the taxable gains on the sales, if any, for federal and state income tax purposes. We cannot assure you that we will dispose of any additional properties or that any acquisitions and/or dispositions will qualify as Section 1031 Exchanges.

In connection with our capital recycling strategy, during the three months ended March 31, 2015, we completed the sale of a land parcel located at 17150 Von Karman in Irvine, California for gross sales proceeds of $26.0 million. In addition, as of March 31, 2015, we classified ten properties as held for sale (one located in Redmond, Washington and nine located in San Diego, California). Four of these properties were sold in April 2015 and the remaining six properties are expected to be sold at the end of the second quarter of 2015 for an aggregate total gross proceeds of approximately $309.2 million. (See “—Factors that May Influence Future Operations” included in this report for additional information). During 2014, we completed the sale of 17 properties and one undeveloped land parcel to unaffiliated third parties in six separate transactions for gross sales proceeds totaling approximately $432.6 million.

Upon the completion of the sale of the ten properties held for sale, we will have disposed of real estate assets totaling $335.2 million thus far in 2015, which is within our initial 2015 capital recycling target range of $250.0 million to $400.0 million of less-strategic asset sales. However, the timing of any potential future disposition transactions will depend on market conditions and other factors including but not limited to our capital needs and our ability to potentially defer some or all of the taxable gains on the sales. We cannot assure you that we will dispose of any additional properties or that future acquisitions and/or dispositions, if any, will qualify as Section 1031 Exchanges.

At-The-Market Stock Offering Program

The following table sets forth information regarding sales of our common stock under our at-the-market stock offering program for the three months ended March 31, 2015:

	Three months  ended March 31, 2015
	(in millions, except share and per share data)
Shares of common stock sold during the three month period	1,507,393
Weighted average price per common share	$	76.09
Aggregate gross proceeds	$	114.7
Aggregate net proceeds after sales agent compensation	$	113.2

The proceeds from the sales were used to fund acquisitions, development expenditures and general corporate purposes including repayment of borrowings under the unsecured revolving credit facility. Since commencement of this program in December 2014, through March 31, 2015, we have sold 1,648,893 shares of common stock having an aggregate gross sales price of $124.7 million, and approximately $175.3 million remained available to be sold under this program. Actual future sales will depend upon a variety of factors, including but not limited to, market conditions, the trading price of the Company’s common stock and our capital needs. We have no obligation to sell the remaining shares available for sale under this program.

Shelf Registration Statement

As discussed above under “—Liquidity and Capital Resources of the Company,” the Company is a well-known seasoned issuer and the Company and the Operating Partnership have an effective shelf registration statement that provides for the public offering and sale from time to time by the Company of its preferred stock, common stock, depository shares and guarantees of debt securities and by the Operating Partnership of its debt securities, in each case in unlimited amounts. The Company evaluates the capital markets on an ongoing basis for opportunities to raise capital, and, as circumstances warrant, the Company and the Operating Partnership may issue securities of all of these types in one or more offerings at any time and from time to time on an opportunistic basis, depending upon, among other things, market conditions, available pricing and capital needs. When the Company receives proceeds from the sales of its preferred or common stock, it generally contributes the net proceeds from those sales to the Operating Partnership in exchange for corresponding preferred or common partnership units of the Operating Partnership. The Operating Partnership may use these proceeds and proceeds from the sale of its debt securities to repay debt, including borrowings under its unsecured revolving credit facility, to develop new or existing properties, to make acquisitions of properties or portfolios of properties, or for general corporate purposes.

Unsecured and Secured Debt

The aggregate principal amount of our unsecured debt and secured debt of the Operating Partnership outstanding as of March 31, 2015 was as follows:

Other Liquidity Uses

Debt Maturities

As of March 31, 2015, we had unsecured debt with principal balances of $325.0 million scheduled to mature in November 2015. We believe our conservative leverage and staggered debt maturities provide us with financial flexibility and enhance our ability to obtain additional sources of liquidity if necessary, and, therefore, we believe 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.

Development Activities

As of March 31, 2015, we had six development projects under construction. These projects have a total estimated investment of approximately $1.1 billion, of which we have incurred approximately $654.5 million and committed an additional $338.0 million as of March 31, 2015. In addition, we currently have additional development projects that we may commence construction on in 2015, depending on market conditions. We currently believe we could potentially spend $50.0 to $75.0 million during 2015 in addition to the amount committed as of March 31, 2015. This total estimated investment is based on market conditions and our anticipation of project approvals. Actual costs could vary depending on changes in circumstances. Ultimate timing of these expenditures may fluctuate given the ultimate progress and leasing status of the projects.

Potential Future Acquisitions

We continue to monitor our target markets and evaluate the acquisition of value add development opportunities and operating properties that we expect to add immediate Net Operating Income to our portfolio or play a strategic role in our future growth.

Other Potential Future Liquidity Uses

We remain a disciplined buyer of development opportunities and office properties and continue to focus on value add opportunities in West Coast markets populated by knowledge and creative based tenants in a variety of industries, including technology, media, healthcare, entertainment and professional services. We expect that any material acquisitions or development activities will be funded with borrowings under the unsecured revolving credit facility, the public or private issuance of debt or equity securities, the disposition of assets under our capital recycling program or through the assumption of existing debt.

In addition, the amounts we are required to spend on tenant improvements and leasing costs we ultimately incur will depend on actual leasing activity. Tenant improvements and leasing costs generally fluctuate in any given period depending on factors such as the type of property, the term of the lease, the type of the lease, the involvement of external leasing agents, and overall market conditions. Capital expenditures may fluctuate in any given period subject to the nature, extent, and timing of improvements required to maintain or improve our properties.

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

We continue to evaluate sources of financing for our business activities, including borrowings under the unsecured revolving credit facility, issuance of public and private equity securities, unsecured debt and fixed-rate secured mortgage financing and proceeds from the disposition of selective assets through our capital recycling program. However, our ability to obtain new financing or refinance existing borrowings on favorable terms could be impacted by various factors, including the state of economic conditions, the state of the credit and equity markets, significant tenant defaults, a decline in the demand for office properties, a decrease in market rental rates or market values of real estate assets in our submarkets and the amount of future borrowings. These events could result in the following:

• Decreases in our cash flows from operations, which could create further dependence on the unsecured revolving 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.

44

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 unsecured revolving credit facility, unsecured term loan facility, unsecured term loan, unsecured senior notes and certain other secured debt arrangements contain covenants and restrictions requiring us to meet certain financial ratios and reporting requirements. Key existing financial covenants and their covenant levels include:

Unsecured Credit Facility, Unsecured Term Loan Facility and Unsecured Term Loan (as defined in the applicable Credit Agreements):	Covenant Level	Actual Performance as of March 31, 2015
Total debt to total asset value	less than 60%	31%
Fixed charge coverage ratio	greater than 1.5x	2.6x
Unsecured debt ratio	greater than 1.67x	2.89x
Unencumbered asset pool debt service coverage	greater than 1.75x	3.62x
Unsecured Senior Notes due 2015, 2018, 2020, 2023 and 2029 (as defined in the applicable Indentures):
Total debt to total asset value	less than 60%	38%
Interest coverage	greater than 1.5x	5.4x
Secured debt to total asset value	less than 40%	8%
Unencumbered asset pool value to unsecured debt	greater than 150%	275%

The Operating Partnership was in compliance with all of its debt covenants as of March 31, 2015. Our current expectation is that the Operating Partnership will continue to meet the requirements of its debt covenants in both the short and long term. However, in the event of a renewed economic slowdown or continued volatility in the credit markets, there is no certainty that the Operating Partnership will be able to continue to satisfy all of the covenant requirements.

Consolidated Historical Cash Flow Summary

The following summary discussion of our consolidated historical cash flow is based on the consolidated statements of cash flows in Item 1. “Financial Statements” and is not meant to be an all-inclusive discussion of the changes in our cash flow for the periods presented below. The cash flow amounts shown below include the activities of discontinued operations. Our historical cash flow activity for the three months ended March 31, 2015 as compared to the three months ended March 31, 2014 is as follows:

	Three Months Ended March 31,
	2015			2014			Dollar Change			Percentage Change
	($ in thousands)
Net cash provided by operating activities	$	54,979		$	45,081		$	9,898		22.0	%
Net cash (used in) provided by investing activities	(77,309		)	97,278			(174,587		)	(179.5	)%
Net cash provided by (used in) financing activities	48,730			(82,202		)	130,932			159.3	%

Operating Activities

Our cash flows from operating activities depend on numerous factors including the occupancy level of our portfolio, the rental rates achieved on our leases, the collectability of rent and recoveries from our tenants, the level of operating expenses, the impact of property acquisitions, completed development projects and related financing activities, and other general and administrative costs. Our net cash provided by operating activities increased by $9.9 million, or 22.0%, for the three months ended March 31, 2015 compared to the three months ended March 31, 2014 primarily as a result of an increase in cash Net Operating Income generated from our Stabilized Development and Redevelopment, Same Store and Acquisition Portfolios. See additional information under the caption “—Results of Operations.”

45

Investing Activities

Our cash flows from investing activities is generally used to fund development and operating property acquisitions, expenditures for development projects, and recurring and nonrecurring capital expenditures for our operating properties, net of proceeds received from dispositions of real estate assets. For the three months ended March 31, 2015, we had net cash used in investing activities of $77.3 million as compared to net cash provided by investing activities of $97.3 million for the three months ended March 31, 2014. This period over period change was due primarily to higher proceeds received from dispositions for the quarter ended March 31, 2014 as compared to the quarter ended March 31, 2015, partially offset by lower acquisitions for the quarter ended March 31, 2015 as compared to March 31, 2014.

Financing Activities

Our cash flows from financing activities is principally impacted by our capital raising activities, net of dividends and distributions paid to common and preferred security holders. For the three months ended March 31, 2015, we had net cash provided by financing activities of $48.7 million as compared to net cash used in financing activities of $82.2 million for the three months ended March 31, 2014. This period over period change was due primarily to our ATM equity issuance activity during the three months ended March 31, 2015.

Off-Balance Sheet Arrangements

As of March 31, 2015 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, gains and losses from sales of depreciable real estate and impairment write-downs associated with depreciable real estate, 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. Our calculation of FFO includes the amortization of deferred revenue related to tenant-funded tenant improvements and excludes the depreciation of the related tenant improvement assets.

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 because 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, 2015 and 2014:

	Three Months Ended March 31,
	2015		2014
	(in thousands)
Net income available to common stockholders	$	39,874	$	96,532
Adjustments:
Net income attributable to noncontrolling common units of the Operating Partnership	815		2,087

Funds From Operations(1)(2)	$	91,532	$	57,221
