EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended March 31, 2016 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, 2016, the Company owned an approximate 97.2% common general partnership interest in the Operating Partnership. The remaining approximate 2.8% 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;

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

◦ Note 15, Supplemental Cash Flow Information of the Company; and

◦ Note 16, Supplemental Cash Flow Information 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, 2016 and 2015

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, 2016:

	Number of Buildings	Rentable Square Feet	Number of Tenants	Percentage  Occupied
Stabilized Office Properties	103	13,671,730	523	94.9	%

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. 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.

During the three months ended March 31, 2016, we stabilized two development projects consisting of 455,340rentable square feet and 185,602 rentable square feet in San Francisco, California which were included in our stabilized portfolio as of March 31, 2016. As of March 31, 2016, the following “lease up” properties and development projects under construction were excluded from our stabilized portfolio. We did not have any redevelopment properties at March 31, 2016.

	Number of Properties/Projects	Estimated Rentable Square Feet
Development projects in “lease-up”	2	443,000
Development projects under construction (1)	2	905,000

________________________

(1) Estimated rentable square feet upon completion.

Our stabilized portfolio also excludes our near-term and future development pipeline, which as of March 31, 2016 was comprised oftendevelopment sites, representing approximately 101gross acres of undeveloped land.

As of March 31, 2016, 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 one future development project located in the state of Washington. As of March 31, 2016, we owned 100% of all of our properties and development projects, excluding two recently completed office properties owned by Redwood City Partners, LLC (“Redwood LLC”), a consolidated subsidiary, and one undeveloped land parcel held at a qualified intermediary 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 that been consolidated for financial reporting purposes.

Ownership and 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.

As of March 31, 2016, the Company owned an approximate 97.2% common general partnership interest in the Operating Partnership. The remaining approximate 2.8% common limited partnership interest in the Operating Partnership as of March 31, 2016 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. As of March 31, 2016, the Company owned an approximate 93% equity interest in Redwood LLC. The remaining interest was owned by an unrelated third party. With the exception of the Operating Partnership and Redwood LLC, all of our subsidiaries are wholly owned.

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, 2016. 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, 2015.

Adoption of New Accounting Pronouncements

Variable Interest Entities

Effective January 1, 2016, the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2015-02 (“ASU 2015-02”), which amended certain guidance with respect to the evaluation of Variable Interest Entities (“VIEs”) and when a reporting entity is required to consolidate certain legal entities. Specifically, the amendments: (i) modify the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities, (ii) eliminate the presumption that a general partner should consolidate a limited partnership, (iii) affect the consolidation analysis of reporting entities that are involved with VIEs, and (iv) provide a scope exception for certain entities. 

Under the new guidance, effective January 1, 2016 the Operating Partnership was determined to be a VIE of the Company as the Operating Partnership is a limited partnership in which the common limited partners do not have substantive kick-out rights or participating rights. However, given that the Company was deemed to be the primary beneficiary of the Operating Partnership, the adoption of this new guidance and the conclusion that the Operating Partnership was a VIE did not have any impact on our consolidated financial statements since the conclusion to consolidate the Operating Partnership still applied. The Operating Partnership was the only new VIE identified as part of the adoption of the guidance as of January 1, 2016.

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

At December 31, 2015 and March 31, 2016, the consolidated financial statements of the Company and the Operating Partnership included two other VIEs in which we were deemed to be the primary beneficiary. One VIE, Redwood LLC, was established in 2013 in connection with an undeveloped land acquisition. The other VIE was established in the fourth quarter of 2015 to facilitate potential future Section 1031 Exchanges to defer taxable gains on dispositions for federal income tax purposes. At March 31, 2016, the impact of consolidating the other VIEs increased the Company’s total assets, liabilities and noncontrolling interests by approximately $208.3 million (of which $187.3 million related to real estate held for investment on our consolidated balance sheet), approximately $26.3 million and approximately $6.7 million, respectively. At December 31, 2015, the impact of consolidating the VIEs increased the Company’s total assets, liabilities and noncontrolling interests by approximately $203.3 million (of which $187.3 million related to real estate held for investment on our consolidated balance sheet), approximately $28.8 million and approximately $6.5 million, respectively.

Reclassification of Debt Issuance Costs

Effective January 1, 2016, the Company adopted FASB ASU No. 2015-03 and No. 2015-15, which requires that debt issuance costs related to a recognized debt liability be presented on the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. However, for line-of-credit arrangements, entities may defer and present debt issuance costs as an asset and amortize the costs ratably over the term of the line of credit arrangement, regardless of whether there are any outstanding borrowings on the line of credit arrangement. As a result of our adoption of the guidance, $1.1 million of deferred financing costs as of December 31, 2015 were reclassified to reduce secured debt, net and $12.0 million of deferred financing costs as of December 31, 2015 were reclassified to reduce unsecured debt, net in the December 31, 2015 balances on our consolidated balance sheets. In addition, $4.6 million of deferred financing costs relating to our unsecured line of credit as of December 31, 2015 were reclassified to prepaid expenses and other assets, net in the December 31, 2015 balances on our consolidated balance sheets. The guidance did not have a material impact on our consolidated financial statements.

Recently Issued Accounting Pronouncements

On February 25, 2016, the FASB issued ASU No. 2016-02 (“ASU 2016-02”) to amend the accounting guidance for leases. The accounting applied by a lessor is largely unchanged under ASU 2016-02. However, the standard requires lessees to recognize lease assets and lease liabilities for leases classified as operating leases on the balance sheet. Lessees will recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it will recognize lease expense for such leases generally on a straight-line basis over the lease term. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 and early adoption is permitted. The Company is currently assessing the impact of the guidance on our consolidated financial statements and notes to our consolidated financial statements.

On August 12, 2015, the FASB issued ASU No. 2015-14 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, 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 and notes to our consolidated financial statements.

On January 5, 2016, the FASB issued ASU No. 2016-01 to amend the accounting guidance on the classification and measurement of financial instruments. The standard requires that all investments in equity securities, including other ownership interests, are carried at fair value through net income. This requirement does not apply to investments that qualify for equity method accounting or to those that result in consolidation of the investee or for which the entity has elected the predictability exception to fair value measurement. Additionally, the standard requires that the portion of the total fair value change caused by a change in instrument-specific credit risk for financial liabilities for which the fair value option has been elected would be recognized in other comprehensive income. Any accumulated amount remaining in other comprehensive income is reclassified to earnings when the liability is extinguished. The Company does not anticipate the guidance to have a material impact on our consolidated financial statements or notes to our consolidated financial statements.

On March 30, 2016, the FASB issued ASU No. 2016-09 (“ASU 2016-09”) to amend the accounting guidance for share-based payment accounting. The areas for simplification in ASU 2016-09 involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for annual periods beginning after December 15, 2016

and interim periods within those annual periods and early adoption is permitted. The Company is currently assessing the impact of the guidance on our consolidated financial statements and notes to our consolidated financial statements.

2.    Acquisitions

Development Project Acquisitions

On March 11, 2016, we acquired an approximately 1.75 acre development site located at 610-620 Brannan Street in San Francisco, CA from an unrelated third party. This land parcel is immediately adjacent to our Flower Mart project in the SOMA submarket of San Francisco and with the addition of this newly acquired site, our Flower Mart project is now comprised of approximately 6.9 acres. The acquisition was funded through $31.0 million in cash and the issuance of 867,701 common units in the Operating Partnership valued at approximately $48.0 million (see Note 9). In addition, the Company paid $2.4 million in seller transaction costs and recorded $4.7 million in accrued liabilities in connection with this acquisition. As of March 31, 2016, the underlying assets were included as undeveloped land and construction in progress on our consolidated balance sheets.

3.    Dispositions

Debt Covenants and Restrictions

The unsecured revolving credit facility, the unsecured term loan facility, the unsecured term loan, the unsecured senior notes, and certain other secured debt arrangements contain covenants and restrictions requiring us to meet certain financial ratios and reporting requirements. Some of the more restrictive financial covenants include a maximum ratio of total debt to total asset value, a minimum fixed-charge coverage ratio, a minimum unsecured debt ratio and a minimum unencumbered asset pool debt service coverage ratio. Noncompliance with one or more of the covenants and restrictions could result in the full principal balance of the associated debt becoming immediately due and payable. We believe we were in compliance with all of our debt covenants as of March 31, 2016.

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

Common Units of the Operating Partnership

The Company owned an approximate 97.2%, 98.1% and 98.0% common general partnership interest in the Operating Partnership as of March 31, 2016, December 31, 2015 and March 31, 2015, respectively. The remaining approximate 2.8%, 1.9% and 2.0% common limited partnership interest as of March 31, 2016, December 31, 2015 and March 31, 2015, respectively, was owned by non-affiliated investors and certain of our executive officers and directors in the form of noncontrolling common units. There were 2,631,276, 1,764,775 and 1,793,170common units outstanding held by these investors, executive officers and directors as of March 31, 2016, December 31, 2015 and March 31, 2015, respectively. The increase in the common units from December 31, 2015 to March 31, 2016 was attributable to 867,701 common units issued in connection with an acquisition (see Note 2) partially offset by a unit redemption.

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

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

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 $158.8 million and $112.0 million as of March 31, 2016 and December 31, 2015, 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.

8.    Stockholders’ Equity of the Company

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. No shares of common stock were sold under this program during the three months ended March 31, 2016. Since commencement of the program through March 31, 2016, we have sold 2,007,767 shares of common stock having an aggregate gross sales price of $150.1 million. As of March 31, 2016, shares of common stock having an aggregate gross sales price of up to $149.9 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.

Common Stock Repurchases

On February 23, 2016, the Company’s board of directors approved a 4,000,000 share increase to the Company’s existing share repurchase program bringing the total current repurchase authorization to 4,988,025 shares. During the three months ended March 31, 2016, the Company repurchased 52,199 shares of common stock at a weighted average price of $55.45 per common share for $2.9 million. As of March 31, 2016, 4,935,826 shares remain eligible for repurchase under the Company’s share repurchase program.

9.    Partners’ Capital of the Operating Partnership

Issuance of Common Units

In March 2016, the Operating Partnership issued 867,701 common units in connection with a development acquisition as discussed in Note 2. Each common unit was valued at $55.36, which was based on a trailing ten-day average of the closing quoted price per share of the Company’s common stock, par value $.01 per share, as reported on the NYSE, as calculated in accordance with the Partnership Agreement.

Common Units Outstanding

The following table sets forth the number of common units held by the Company and the number of common units held by non-affiliated investors and certain of our executive officers and directors in the form of noncontrolling common units as well as the ownership interest held on each respective date:

	March 31, 2016		December 31, 2015		March 31, 2015

10.    Share-Based Compensation

Stockholder Approved Equity Compensation Plans

As of March 31, 2016, we maintained one share-based incentive compensation plan, the Kilroy Realty 2006 Incentive Award Plan, as amended (the “2006 Plan”). As of March 31, 2016, 1,394,096 shares were available for grant under the 2006 Plan. The calculation of shares available for grant is presented after taking into account a reserve for a sufficient number of shares to cover the vesting and payment of 2006 Plan awards that were outstanding on that date, including performance-based vesting awards at (i) levels actually achieved for the performance conditions (as defined below) and (ii) at target levels for the market conditions (as defined below) applicable to these awards.

2016 Share-Based Compensation Grants

On January 28, 2016, the Executive Compensation Committee of the Company’s Board of Directors awarded 294,821 restricted stock units (“RSUs”) to certain officers of the Company under the 2006 Plan, which included 168,077 RSUs (at the target level of performance), or 57%, that are subject to market and performance-based vesting requirements (the “2016 Performance-Based RSUs”) and 126,744 RSUs, or 43%, that are subject to time-based vesting requirements (the “2016 Time-Based RSUs”).

On January 9, 2016, the Executive Compensation Committee of the Company’s Board of Directors awarded 33,910 RSUs to the Company’s Chief Operating Officer under the 2006 Plan (the “2016 Special RSUs”).

2016 Performance-Based RSU Grant

The 2016 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, 2016 and also based upon the average annual relative total stockholder return ranking for the Company compared to an established comparison group of companies (the “market condition”) for the three-year period ending December 31, 2018. The 2016 Performance-Based RSUs are also subject to a three-year service vesting provision and are scheduled to cliff vest at the end of the three-year period. The number of 2016 Performance-Based RSUs ultimately earned could fluctuate from the target number of 2016 Performance-Based RSUs granted based upon the levels of achievement for both the performance condition and the market condition. The estimate of the number of 2016 Performance-Based RSUs earned are evaluated quarterly during the 2016 performance period based on our estimate as to the 2016 FFO per share performance measured against the applicable goals. As of March 31, 2016, 168,077 2016 Performance-Based RSUs are estimated to be earned based on the Company’s estimate of 2016 FFO per share performance measured against the applicable goals, and the compensation cost recorded to date for this program was based on that estimate. Compensation expense for the 2016 Performance-Based RSU grant will be recorded on a straight-line basis over the three-year period.

Each 2016 Performance-Based RSU represents the right to receive one share of our common stock in the future. The total fair value of the 2016 Performance-Based RSU grant was $9.6 million at January 28, 2016 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 2016 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, 2016, we recorded compensation expense based upon the $57.08 fair value at January 28, 2016. The following table summarizes the assumptions utilized in the Monte Carlo simulation pricing model:

	Fair Value Assumptions
Fair value per share at January 28, 2016	$57.08
Expected share price volatility	26.00%
Risk-free interest rate	1.13%
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 28, 2016. The expected life of the RSUs is equal to the remaining 2.9 year vesting period at January 28, 2016.

2016 Time-Based RSU Grant

The 2016 Time-Based RSUs are scheduled to vest in three equal installments beginning on January 5, 2017 through January 5, 2019. Compensation expense for the 2016 Time-Based RSUs will be recognized on a straight-line basis over the three-year service vesting period. Each 2016 Time-Based RSU represents the right to receive one share of our common stock in the future. The total fair value of the 2016 Time-Based RSU grant was $7.1 million, which was based on the $56.23 closing share price of the Company’s common stock on the NYSE on January 28, 2016.

2016 Special RSU Grant

The 2016 Special RSUs are scheduled to vest in four equal installments beginning on December 31, 2016 through December 31, 2019 based on the achievement of certain metrics. Compensation expense for the 2016 Special RSUs will be recognized on a straight-line basis over the four-year service vesting period. Each 2016 Special RSU represents the right to receive one share of our common stock in the future. The total fair value of the 2016 Special RSU grant was $2.0 million, which was based on the $58.98 closing share price of the Company’s common stock on the NYSE on January 8, 2016 for the time-based portion, and the estimated fair value at date of grant for the performance-based portion.

Share-Based Compensation Cost Recorded During the Period

The total compensation cost for all share-based compensation programs was $5.9 million and $4.3 million for the three months ended March 31, 2016 and 2015, respectively. Of the total share-based compensation costs, $1.2 million and $0.7 million was capitalized as part of real estate assets for the three months ended March 31, 2016 and 2015, respectively. As of March 31, 2016, there was approximately $44.1 million of total unrecognized compensation cost related to nonvested incentive awards granted under share-based compensation arrangements that is expected to be recognized over a weighted-average period of 2.1 years. The remaining compensation cost related to these nonvested incentive awards had been recognized in periods prior to March 31, 2016.

11.    Commitments and Contingencies

General

As of March 31, 2016, we had commitments of approximately $461.1 million, excluding our ground lease commitments, for contracts and executed leases directly related to our operating properties.

Environmental Matters

We follow the policy of monitoring all of our properties, both acquisition and existing stabilized portfolio properties, for the presence of hazardous or toxic substances. 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, 2016, we had accrued environmental remediation liabilities of approximately $26.7 million recorded on our consolidated balance sheets in connection with recent development acquisitions and certain of our development projects. 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 on certain of these projects, potential additional environmental costs are not reasonably estimable at this time.

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, 2015 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 97.2%, 98.1% and 98.0% general partnership interest in the Operating Partnership as of March 31, 2016, December 31, 2015 and March 31, 2015, 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

Development Program We believe that a portion of our long-term future growth will continue to come from the completion of our in-process development projects as well as, subject to market conditions, executing on our near-term and future development pipeline, including expanding entitlements. Over the past several years, we increased our focus on development opportunities and expanded our near-term and 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 generally favor starting projects that are pre-leased.

25

Completed Development Projects

During the three months ended March 31, 2016, we completed construction and stabilized the following two office development projects.

• 350 Mission Street, SOMA, San Francisco, California, which we acquired in October 2012 and was stabilized in March 2016. This development project has a total estimated investment of approximately $279.6 million and encompasses approximately 455,340 rentable square feet. The office component of this project is 100% leased to salesforce.com, inc.

• 333 Brannan Street, SOMA, San Francisco, California, which we acquired in July 2012 and was stabilized in March 2016. This development project has a total estimated investment of approximately $101.5 million and encompasses approximately 185,602 rentable square feet. The office component of the project is 100% leased to Dropbox, Inc.

Projects in “Lease-Up”

As of March 31, 2016, we had two development projects in the “lease-up” phase.

• Columbia Square Office Phase 2, Hollywood, California, located in the heart of Hollywood, California, two blocks from the corner of Sunset Boulevard and Vine Street. This project is comprised of three buildings totaling approximately 370,000 rentable square feet with a total estimated investment of $220 million. The building core and shell of the project, which is currently 80% committed, was completed in the first quarter of 2016, and is expected to be stabilized in the first quarter of 2017.

• The Heights at Del Mar, Del Mar, California, a 73,000 square foot office project that has a total estimated investment of approximately $45 million. The building core and shell of the project was completed in the fourth quarter of 2015 and is currently 44% committed.

Projects Under Construction

As of March 31, 2016, we had two projects that were under construction.

• The Exchange on 16th, Mission Bay, San Francisco, California, was acquired in May 2014 and we commenced construction in June 2015. This project encompasses approximately 700,000 gross rentable square feet in four buildings and represents a total estimated investment of approximately $485 million. Construction is currently in process and the building core and shell is currently estimated to be completed in the second half of 2017.

• Columbia Square - Residential, Hollywood, California, the residential component of the Columbia Square project, which encompasses approximately 205,000 square feet, will be a mix of high-end long-term rentals and extended stay apartment homes and has an estimated investment of approximately $160 million. Construction of this project is currently expected to be completed in the second quarter of 2016, and the project is expected to be leased-up through the second quarter of 2017.

Near-Term and Future Development Pipeline

As of March 31, 2016, our near-term development pipeline included four additional undeveloped land holdings located in various submarkets in San Diego County, the San Francisco Bay Area, Greater Seattle and Los Angeles with an aggregate cost basis of approximately $402.2 million at March 31, 2016, on which we believe we could develop approximately 2.5 million rentable square feet at a total estimated investment of over $1.5 billion, depending on successfully obtaining entitlements and market conditions.

26

The following table sets forth information about our near-term development pipeline as of the date of this filing.

Near-Term Development Pipeline (1)	Location	Potential Start Date (2)	Approx. Developable Square Feet	Total Estimated Investment		Total Costs as of 3/31/2016 (3)
100 Hooper	San Francisco	2016	400,000	$	255	$	91.2

One Paseo	Del Mar	2016	TBD	TBD		186.3
Total Near-Term Development Pipeline						$	402.2

________________________

(1) Project timing, costs, developable square feet and scope could change materially from estimated data provided due to one of more of the following:  any significant changes in the economy, market conditions, our markets, tenant requirements and demands, construction costs, new office supply, regulatory and entitlement processes, and project design.

(2) Potential start dates assume successfully obtaining all entitlements and approvals necessary to commence construction. Actual commencement is subject to extensive consideration of market conditions and economic factors. 100 Hooper is fully-entitled with Proposition M allocation.

(3) Represents cash paid and costs incurred as of March 31, 2016.

(4) Consists of four adjacent parcels in the South Lake Union submarket of Seattle.

As of March 31, 2016, our longer term future development pipeline included additional undeveloped land holdings located in various submarkets in San Diego County and the San Francisco Bay Area with an aggregate cost basis of approximately $316.5 million at March 31, 2016, at which we believe we could develop more than 3.0 million rentable square feet, depending on successfully obtaining entitlements and market conditions.

Decreases in our development activities could cause a decrease in the average development asset balances qualifying for interest and other carry cost and internal cost capitalization in future periods. During the threemonths ended March 31, 2016, we capitalized interest on in-process development projects and development pipeline projects with an average aggregate cost basis of approximately $1.3 billion, as it was determined these projects qualified for interest and other carry cost capitalization under GAAP. For the three months ended March 31, 2016 and 2015, we capitalized $14.3 million and $10.9 million, respectively, of interest to our qualifying development projects. For the three months ended March 31, 2016 and 2015, we capitalized $4.6 million and $3.5 million, respectively, of internal costs to our qualifying development projects.

Acquisitions. During the three months ended March 31, 2016, we acquired a 1.75 acre land parcel in San Francisco, California for a purchase price of $31.0 million in cash, the issuance of 867,701 common units in the Operating Partnership valued at approximately $48.0 million and $2.4 million in seller transaction costs. This land parcel is immediately adjacent to our Flower Mart project in the SOMA submarket of San Francisco and with the addition of this newly acquired site, our Flower Mart project is now comprised of approximately 6.9 acres.During 2015, we acquired two development opportunities for an aggregate cash purchase price of approximately $127.5 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.

As part of our growth strategy, which is highly dependent on market conditions and business cycles, among other factors, we continue to evaluate strategic opportunities and remain a disciplined buyer of development and redevelopment opportunities as well as value-add operating properties.  We continue to focus on growth 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.  Against the backdrop of market volatility, we expect to manage a strong balance sheet, execute on our development program and selectively evaluate opportunities that either add immediate Net Operating Income to our portfolio or play a strategic role in our future growth.

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. In addition, acquisitions are subject to various risks and uncertainties and we may be unable to complete an acquisition after making a nonrefundable deposit or incurring acquisition-related costs.

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 properties or lower return assets into capital used to fund new operating and development acquisitions, to finance development and redevelopment expenditures, 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. See the “Liquidity and Capital Resources of the Operating Partnership – Liquidity Sources” section for further information regarding our capital recycling strategy.

27

In connection with our capital recycling strategy, during the three months ended March 31, 2016, we completed the sale of four office properties and one undeveloped land parcel located in San Diego, California, to unaffiliated third parties for total gross sales proceeds of $266.8 million. Both the operating properties and the land parcel were classified as held for sale as of December 31, 2015. During 2015, we completed the sale of ten office properties and one undeveloped land parcel to unaffiliated third parties for total gross sales proceeds of $335.2 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 that we will dispose of any additional properties or that we will be able to identify and complete the acquisition of a suitable replacement property to effect a Section 1031 Exchange. 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, 2016.

________________________

(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 72,031 and 31,711 square feet, respectively, for the three months ended March 31, 2016, 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, 2016, 21leases totaling130,978rentable square feet were signed but not commenced as of March 31, 2016.

As of March 31, 2016, we believe that the weighted average cash rental rates for our stabilized portfolio are approximately 15% below 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. We believe that cash rental rates for our San Diego stabilized properties are approximately 8% above current market rental rates in that region.

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 and regional market fundamentals, including the pace

28

of regional economic growth and access to capital. Therefore, we cannot give any assurance that leases will be renewed or that available space will be re-leased at rental rates equal to or above the current market rates. Additionally, decreased demand and other negative trends or unforeseeable events that impair our ability to timely renew or re-lease space could have further negative effects on our future financial condition, results of operations and cash flows.

Scheduled Lease Expirations. The following table sets forth certain information regarding our lease expirations for our stabilized portfolio for the remainder of 2016 and the next five years.

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 0.7 million rentable square feet, or 5.1%, of currently available space in our stabilized portfolio, leases representing approximately 4.1% and 9.9% of the occupied square footage of our stabilized portfolio are scheduled to expire during 2016 and 2017, respectively. The leases scheduled to expire during the remainder of 2016 and in 2017 represent approximately 1.8 million rentable square feet or 12.2% of our total annualized base rental revenue. We believe that the weighted average cash rental rates are approximately 15% below the current average market rental rates for leases scheduled to expire during the remainder of 2016 and in 2017, 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 2016, 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, 2016, there was approximately $44.1 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 2.1 years. The $44.1 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, 2016, our stabilized portfolio was comprised of 103 office properties encompassing an aggregate of approximately 13.7 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 result of which is a higher economic return on the property. 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. Our stabilized portfolio also excludes our near-term and future development pipeline, which as of March 31, 2016 was comprised of ten potential development sites, representing approximately 101 gross acres of undeveloped land on which we believe we have the potential to develop over 5.5 millionsquare feet of office space, depending upon economic conditions.

As of March 31, 2016, the following properties were excluded from our stabilized portfolio:

	Number of Properties/Projects	Estimated Rentable Square Feet
Development projects in “lease-up”	2	443,000

Results of Operations

Net Operating Income

Management internally evaluates the operating performance and financial results of our stabilized portfolio based on Net Operating Income. 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).

Net Operating Income 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, 2015 and still owned and included in the stabilized portfolio as of March 31, 2016;

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

◦ Two office development projects that were completed and stabilized in March 2016;

◦ Two office development projects comprising four office buildings that were completed and stabilized in the fourth quarter of 2015; and

• Dispositions and Other – which includes the results of the four properties disposed of in 2016, the ten properties disposed of in 2015, and expenses for certain of our in-process, near-term and future development projects.

The following table sets forth certain information regarding the property groups within our stabilized portfolio as of March 31, 2016:

Net Operating Income remained generally consistent for the three months ended March 31, 2016 as compared to the three months ended March 31, 2015 driven by the following activity:

• An increase in Net Operating Income of $0.1 million attributable to the Same Store Properties primarily resulting from:

• An increase in rental income of $2.8 million primarily due to an increase from new leases and renewals at higher rates primarily in the San Francisco Bay Area and Los Angeles regions;

• An offsetting decrease in tenant reimbursements of$2.9 million primarily due to the following:

◦ $1.8 million reduction as a result of a change in estimate due to lower supplemental taxes primarily at two properties we developed and stabilized in 2014; and

◦ $0.7 million decrease from a number of lease renewals with base year resets and adjustments;

34

• An offsetting decrease in other property income of $0.4 milliondue to lease termination fees recognized mainly from one tenant during the three months ended March 31, 2015; and

• A partially offsetting decrease in property and related expenses of $0.6 million primarily due to the following:

◦ $1.1 million increase in property expenses due to an increase in security, janitorial, engineering, and various other reimbursable expenses and an increase in non-reimbursable expenses due to an insurance refund received in 2015; partially offset by

◦ $1.5 million decrease in real estate taxes primarily due to a reduction in supplemental taxes at two properties we developed and stabilized in 2014;

• An increase in Net Operating Income of $7.7 millionattributable to the Stabilized Development Properties primarily attributable to the properties completed and/or stabilized in the three months ended December 31, 2015 and March 31, 2016;

• A decrease in Net Operating Income of $7.8 million attributable to Dispositions and Other Properties due to the sale of four buildings during the three months ended March 31, 2016 and ten buildings during the last nine months of 2015.

Other Expenses and Income

General and Administrative Expenses

General and administrative expenses increased by approximately $0.7 million, or 5.2%, for the three months ended March 31, 2016 compared to the three months ended March 31, 2015 primarily due to an increase in compensation related expenses primarily related to growth of the Company.

Depreciation and Amortization

Depreciation and amortization decreased by approximately $1.0 million, or 2.0%, for the three months ended March 31, 2016 compared to the three months ended March 31, 2015, primarily due to the following:

• A decrease of $3.8 million attributable to sold properties; partially offset by

• An increase of $2.6 million attributable to the Stabilized Development Properties.

Interest Expense

The following table sets forth our gross interest expense, including debt discounts/premiums and deferred financing cost amortization, net of capitalized interest, including capitalized debt discounts/premiums and deferred financing cost amortization for the three months ended March 31, 2016 and 2015:

	Three Months Ended March 31,
	2016			2015			Dollar Change			Percentage Change
	(in thousands)
Gross interest expense	$	26,175		$	27,749		$	(1,574	)	(5.7	)%
Capitalized interest and deferred financing costs	(14,346		)	(10,871		)	(3,475		)	32.0	%
Interest expense	$	11,829		$	16,878		$	(5,049	)	(29.9	)%

Gross interest expense, before the effect of capitalized interest, decreased $1.6 million, or 5.7%, for the three months ended March 31, 2016 compared to the three months ended March 31, 2015 primarily due to a decrease in the average outstanding debt balance for the three months ended March 31, 2016 as compared to the three months ended March 31, 2015. Capitalized interest and deferred financing costs increased $3.5 million, or 32.0% for the three months ended March 31, 2016 compared to the three months ended March 31, 2015 primarily attributable to an increase in our development activity, which resulted in higher average asset balances qualifying for interest capitalization.

Liquidity and Capital Resources of the Company

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

The Company’s business is operated primarily through the Operating Partnership. Distributions from the Operating Partnership are the Company’s 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, 2016 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. However, while the 2015 regular quarterly distributions were sufficient to distribute 100% of the Company’s 2015 taxable income, they did not result in a return of capital to its stockholders. As the Company intends to maintain distributions at a level sufficient to meet the REIT distribution requirements and minimize the potential of any income or excise taxes, it will continue to evaluate whether the current levels of distribution are sufficient to do so for 2016. In addition, in the eventthat the Company is unable to identify and complete the acquisition of suitable replacement properties to effect Section 1031 Exchanges or is unable to successfully complete Section 1031 Exchanges to defer some or all of the taxable gains related to property dispositions completed to date in 2016 or future property dispositions, the Company may elect to distribute a special dividend to its commons shareholders and common unitholders in order minimize 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 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 23, 2016, the Board of Directors declared a regular quarterly cash dividend of $0.35 per share of common stock payable on April 13, 2016 to stockholders of record on March 31, 2016 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 13, 2016 was $33.0 million.

On February 23, 2016, 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 15, 2016 and ending on and including May 14, 2016. The dividend will be payable on May 15, 2016 to Series G Preferred and Series H Preferred stockholders of record on April 30, 2016. As April 30, 2016 falls on a Saturday, the effective record date for the dividend will be Friday, April 29, 2016. The quarterly dividends payable on May 15, 2016 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, 2016, our total debt as a percentage of total market capitalization was 27.6% and our total debt and liquidation value of our preferred equity as a percentage of total market capitalization was 30.0%, which was calculated based on the closing price per share of the Company’s common stock of $61.87 on March 31, 2016 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 the disposition of assets through our capital recycling program;

• Proceeds from additional secured or unsecured debt financings; and

• Proceeds from public or private issuance of debt or equity securities.

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;

• Repurchases of outstanding common stock of the Company; 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.

Unsecured Revolving Credit Facility

The following table summarizes the balance and terms of our unsecured revolving credit facility as of March 31, 2016 and December 31, 2015:

	March 31, 2016			December 31, 2015
	(in thousands)
Outstanding borrowings	$	75,000		$	—
Remaining borrowing capacity	525,000			600,000

Interest rate (2)	1.49		%	—		%
Facility fee-annual rate (3)	0.200%
Maturity date	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 1.050% as of March 31, 2016 and December 31, 2015.

(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, 2016 and December 31, 2015, $4.3 million and $4.6 million of unamortized deferred financing costs, respectively, remained to be amortized through the maturity date of our unsecured revolving credit facility, which are included in prepaid expenses and other assets, net on our consolidated balance sheets.

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.

In connection with our capital recycling strategy, during the three months ended March 31, 2016, we completed the sale of four operating properties and one undeveloped land parcel located in San Diego, California to unaffiliated third parties for gross sales proceeds of $266.8 million.During 2015, we completed the sale of ten operating properties and one undeveloped land parcel to unaffiliated third parties for gross sale proceeds of $335.2 million.

We currently anticipate that in 2016 we could raise capital through our dispositions program ranging from approximately $350 million to $650 million, with a midpoint of $500 million, including the $266.8 million we completed in January 2016 as discussed above. However, 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. In addition, we cannot assure you that we will dispose of any additional properties or that we will be able to identify and complete the acquisition of suitable replacement properties to effect Section 1031 Exchanges to defer some or all of the taxable capital gains related to our capital recycling program.

At-The-Market Stock Offering Program

Since commencement of our at-the-market stock offering program in December 2014, through March 31, 2016, we have sold 2,007,767 shares of common stock having an aggregate gross sales price of $150.1 million, and approximately $149.9 million remained available to be sold under this program. No shares of common stock were sold under this program during the three months ended March 31, 2016. 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.

39

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 the unsecured debt and secured debt of the Operating Partnership outstanding as of March 31, 2016 was as follows:

We may start additional construction during the remainder of 2016 (see “—Development Activities” for additional information).

Other Liquidity Uses

Development Activities

As of March 31, 2016, we had two development projects under construction.  These projects have a total estimated investment of approximately $645 million, of which we have incurred approximately $290 million and committed an additional $279 million as of March 31, 2016.  As of March 31, 2016, we also had two projects in the "lease-up" phase. These projects have a total estimated investment of approximately $265 million, of which we have incurred approximately $206 million as of March 31, 2016 and are contractually committed to spend approximately $37 million under executed leases.  Depending on market conditions, we expect to incur the remaining $23 million for these ‘lease-up” projects through stabilization.  In addition, depending on market condition, we currently estimate we could potentially spend an additional $0 - $175 million on our current development projects and potential future development pipeline projects that we may commence construction on in 2016.  Ultimate timing of these expenditures may fluctuate given construction progress and leasing status of the projects.  We expect that any material additional development activities will be funded with borrowings under the unsecured revolving credit facility, the public or private issuance of debt or equity securities or the disposition of assets under our capital recycling program.

41

Potential Future Acquisitions

During the year ended March 31, 2016, we acquired one development opportunity for $31.0 million in cash and the issuance of 867,701 common units in the Operating Partnership valued at approximately $48.0 million and $2.4 million in seller transaction costs. In 2015, we acquired two development opportunities for approximately $127.5 million in cash. These transactions were funded through various capital raising activities and, in selected instances, the assumption of existing indebtedness and issuance of common stock of the Company or common units in the Operating Partnership.

As part of our growth strategy, which is highly dependent on market conditions and business cycles, among other factors, we continue to evaluate strategic opportunities and remain a disciplined buyer of development and redevelopment opportunities as well as value-add operating properties.  We continue to focus on growth 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.  Against the backdrop of market volatility, we expect to manage a strong balance sheet, execute on our development program and selectively evaluate opportunities that either add immediate Net Operating Income to our portfolio or play a strategic role in our future growth. We expect that any material acquisitions 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.

Debt Maturities

As of March 31, 2016, $7.4 million in principal payments will be paid during the year ended December 31, 2016 and our next debt maturity of $64.3 million of secured debt is scheduled to occur in February 2017, which we have the option to prepay without penalty in the fourth quarter of 2016. 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.

Share Repurchases

On February 23, 2016, the Company’s board of directors approved a 4,000,000 share increase to the Company’s existing share repurchase program bringing the total current repurchase authorization to 4,988,025 shares. During the three months ended March 31, 2016, the Company repurchased 52,199 shares of common stock at a weighted average price of $55.45 per common share totaling $2.9 million. As of March 31, 2016, 4,935,826 shares remain eligible for repurchase under the Company’s share-repurchase program. Under this program, repurchases may be made in open market transactions at prevailing prices or through privately negotiated transactions. We may elect to repurchase shares of our common stock under this program in the future depending upon various factors, including market conditions, the trading price of our common stock and our other uses of capital. This program does not have a termination date, and repurchases may be discontinued at any time. We intend to fund repurchases, if any, primarily with the proceeds from property dispositions.

Other Potential Future Liquidity Uses

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 the macro economy, 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 our future borrowings. These events could result in the following:

42

• 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.

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, 2016
Total debt to total asset value	less than 60%	28%
Fixed charge coverage ratio	greater than 1.5x	2.5x
Unsecured debt ratio	greater than 1.67x	3.30x
Unencumbered asset pool debt service coverage	greater than 1.75x	3.57x
Unsecured Senior Notes due 2018, 2020, 2023, 2025 and 2029 (as defined in the applicable Indentures):
Total debt to total asset value	less than 60%	34%
Interest coverage	greater than 1.5x	7.4x
Secured debt to total asset value	less than 40%	6%
Unencumbered asset pool value to unsecured debt	greater than 150%	303%

The Operating Partnership was in compliance with all of its debt covenants as of March 31, 2016. 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. Our historical cash flow activity for the three months ended March 31, 2016 as compared to the three months ended March 31, 2015 is as follows:

	Three Months Ended March 31,
	2016			2015			Dollar Change			Percentage Change
	($ in thousands)
Net cash provided by operating activities	$	78,204		$	54,979		$	23,225		42.2	%
Net cash used in investing activities	(126,733		)	(77,309		)	(49,424		)	63.9	%
Net cash provided by financing activities	30,666			48,730			(18,064		)	(37.1	)%

43

Operating Activities

Our cash flows from operating activities depends on numerous factors including the occupancy level of our portfolio, the rental rates achieved on our leases, the collectability of rent and recoveries from our tenants, the level of operating expenses, the impact of property acquisitions, completed development projects and related financing activities, and other general and administrative costs.Our net cash provided by operating activities increased by $23.2 million, or 42.2%, for the three months ended March 31, 2016 compared to the three months ended March 31, 2015 primarily as a result the expiration of the free rent period for certain leases, resulting in higher cash rental revenue. See additional information under the caption “—Results of Operations.”

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. Our net cash used in investing activities increased by $49.4 million or 63.9%for the three months ended March 31, 2016 compared to the three months ended March 31, 2015 primarily due to property disposition proceeds held at a qualified intermediary at March 31, 2016.

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. Net cash provided by financing activities decreased by $18.1 million or 37.1% for the three months ended March 31, 2016 compared to the three months ended March 31, 2015 due primarily to lower capital raising activities during the three months ended March 31, 2016 as compared to the three months ended March 31, 2015.

Off-Balance Sheet Arrangements

As of March 31, 2016 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 also add back net income attributable to noncontrolling common units of the Operating Partnership because we report FFO attributable to common stockholders and common unitholders.

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, 2016 and 2015:

	Three Months Ended March 31,
	2016			2015

APPENDIX A

TERMS AND CONDITIONS OF

RESTRICTED STOCK UNITS AND DIVIDEND EQUIVALENT RIGHTS

1.Grant. The Company hereby grants to the Participant, effective as of the Grant Date, an aggregate Award with respect to the total number of RSUs set forth in the Grant Notice and corresponding Dividend Equivalents, subject to the terms and conditions contained in this Agreement and the Plan.

2.RSUs. Each RSU that vests on an applicable Vesting Date shall represent the right to receive payment, in accordance with Section 6 below, of one share of Stock.Unless and until an RSU vests, the Participant will have no right to payment in respect of any such RSU. Prior to actual payment in respect of any vested RSU, such RSU will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company.

3.Dividend Equivalent Rights. Each RSU granted hereunder is hereby granted in tandem with a corresponding Dividend Equivalent that shall remain outstanding from the Grant Date through the earlier to occur of (a) the termination or forfeiture for any reason of the RSU to which such Dividend Equivalent corresponds, or (b) the delivery to the Participant of the shares of Stock underlying the RSU to which such Dividend Equivalent corresponds. The Participant shall not be entitled to any payment under a Dividend Equivalent with respect to any dividend with a record date that occurs prior to the Grant Date or after the termination of such RSU for any reason, whether due to payment, forfeiture of the RSU or otherwise. Dividend Equivalents and any amounts that may become distributable in respect thereof shall be treated separately from the RSUs and the rights arising in connection therewith for purposes of the designation of time and form of payments required by Section 409A of the Code.

(a)Time-Vest RSUs. Each Dividend Equivalent linked to a Time-Vest RSU shall represent the right to receive the cash value of any cash dividend(s) that the Participant would have received in respect of the share of Stock underlying the RSU to which such Dividend Equivalent is linked, had such share of Stock been outstanding on the applicable dividend record date. Any amounts payable in respect of Dividend Equivalents linked to Time-Vest RSUs shall be paid in cash or cash equivalents as and when the cash dividends in respect of which such Dividend Equivalent payments arise are paid to holders of Common Stock, without regard to the vested status of the underlying Time-Vest RSUs.

(b)Performance-Vest RSUs. With respect to Performance-Vest RSUs, Dividend Equivalent payments shall be paid in cash or Stock (i) only with respect to that number of shares of Stock underlying Performance-Vest RSUs that vest in accordance herewith, (ii) with a value determined as if such shares of Stock underlying vested Performance-Vest RSUs (A) had been outstanding for the same portion of the Performance Period during which related Performance-Vest RSUs were outstanding, and (B) had received all dividend payments over such period in notional shares of Stock equal in value to the dividends declared over such period divided by the Fair Market Value on the applicable dividend declaration date (rounded to the nearest whole share of Stock),

A-1

and (iii) at such time as payment is made with respect to the RSU to which such Dividend Equivalent is linked. To the extent any Dividend Equivalents paid pursuant to this Section 3(b) are paid in cash, such notional shares of Stock shall be converted to a cash value based on the Fair Market Value on the day prior the date of payment of the RSU to which such Dividend Equivalent is linked. If the Performance-Vest RSU linked to a Dividend Equivalent fails to vest and is forfeited for any reason, then (x) the linked Dividend Equivalent shall be forfeited as well, (y) any amounts otherwise payable in respect of such Dividend Equivalent shall be forfeited without payment, and (z) the Company shall have no obligations in respect of such Dividend Equivalent.

4.Vesting and Forfeiture. The RSUs (and, with respect to Performance-Vest RSUs, their corresponding Dividend Equivalents) shall vest in accordance with the vesting schedule provided in the Grant Notice to which this Appendix is attached.

5.Termination of RSUs and Dividend Equivalents. Upon the Participant’s termination as an Employee, all RSUs that have not vested as of such termination (taking into consideration any vesting that may occur in connection with such termination) and all corresponding Dividend Equivalents shall automatically be forfeited and canceled without payment of consideration therefor. In addition, to the extent that any unvested Performance-Vest RSUs become ineligible to vest based on the Company’s 2019 performance, such Performance-Vest RSUs and their corresponding Dividend Equivalents shall automatically be forfeited upon the Company’s determination of the applicable 2019 performance results. The RSUs and all corresponding Dividend Equivalents shall be subject to forfeiture and cancelation in accordance with Section 11(c) of the Employment Agreement and Section 6 of the Non-Competition, Non-Solicitation and Non-Disclosure Agreement, dated December 31, 2015, by and between the Company and the Participant (the “Non-Competition, Non-Solicitation and Non-Disclosure Agreement”).

6.Payment of RSUs. As soon as administratively practicable following the vesting of any RSUs on an applicable Vesting Date in accordance with Section 4 above, but in no event later than thirty (30) days after the applicable Vesting Date, the Company shall deliver to the Participant (or any transferee permitted under Section 9 below) a number of shares of Stock (either by delivering one or more certificates for such shares of Stock or by entering such shares of Stock in book entry form, as determined by the Committee in its sole discretion) equal to the number of RSUs that vest on the applicable Vesting Date, unless such RSUs terminate prior to the given vesting date pursuant to Section 5 above. Notwithstanding the foregoing, in the event shares of Stock cannot be issued pursuant to Section 10.5 of the Plan or are delayed under Section 10 below, the shares of Stock shall be issued pursuant to the preceding sentence as soon as administratively practicable after the Committee determines that shares of Stock can again be issued in accordance with such Section. In no event shall any such delay in the issuance of shares of Stock impact the payment timing applicable to Dividend Equivalents payable in cash.

7.Tax Withholding. The Company shall have the authority and the right to deduct, withhold or require a Participant or Beneficiary to remit to the Company an amount sufficient to satisfy federal, state, local and foreign taxes (including without limitation any income and employment tax obligations) required by law to be withheld with respect to any taxable event arising in connection with the RSUs and/or the Dividend Equivalents. To the extent that such

A-2

obligations arise at the time that the RSUs are paid to the Participant in shares of Stock, the Committee may, in its sole discretion and in satisfaction of the foregoing requirement, allow the Participant to elect to have the Company withhold shares of Stock otherwise issuable under this Agreement (or allow the return of shares of Stock) having a Fair Market Value equal to the sums required to be withheld, provided, that the number of shares of Stock which may be so withheld (or returned) with respect to a taxable event arising in connection with the RSUs and/or the Dividend Equivalents shall be limited to the number of shares which have a Fair Market Value on the date of withholding equal to the aggregate amount of such liabilities based on the minimum statutory withholding rates for federal, state and local income tax and payroll tax purposes that are applicable to such supplemental taxable income.

8.Rights as Stockholder. Neither the Participant nor any person claiming under or through the Participant will have any of the rights or privileges of a stockholder of the Company in respect of any shares of Stock deliverable hereunder unless and until certificates representing such shares of Stock will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to the Participant or any person claiming under or through the Participant

9.Non-Transferability. Neither the RSUs, the Dividend Equivalents nor any interest or right therein or part thereof shall be transferred, assigned, pledged or hypothecated by the Participant in any way in favor of any party other than the Company or the TRS, the Partnership or any Subsidiary (each, an “Affiliate”) (whether by operation of law or otherwise) and shall not be subjected to any lien, obligation or liability of the Participant to any party other than the Company or an Affiliate, other than by the laws of descent and distribution. Upon any attempt by the Participant to transfer, assign, pledge, hypothecate or otherwise dispose of this grant, or any right or privilege conferred hereby, or upon any attempted sale by the Participant under any execution, attachment or similar process, this grant and the rights and privileges conferred hereby shall immediately become null and void. Notwithstanding the foregoing, the Company may assign any of its rights under this Agreement to single or multiple assignees and this Agreement shall inure to the benefit of the successors and assigns of the Company.

10.Distribution of Stock. The Company shall not be required to record any shares of Stock in the name of the Participant in the books and records of the Company’s transfer agent, and the Company shall not be required to issue or deliver any certificate or certificates for any shares of Stock prior to the fulfillment of all of the following conditions: (a) the admission of such shares to listing on all stock exchanges on which the Company’s common stock is then listed, (b) the completion of any registration or other qualification of such shares under any state or federal law or under rulings or regulations of the Securities and Exchange Commission or other governmental regulatory body, which the Committee shall, in its sole and absolute discretion, deem necessary and advisable, and (c) the obtaining of any approval or other clearance from any state or federal governmental agency that the Committee shall, in its absolute discretion, determine to be necessary or advisable. In the event that the Company delays a distribution or payment in settlement of RSUs because it determines that the issuance of shares of Stock in settlement of such RSUs will violate Federal securities laws or other applicable law, such distribution or payment shall be made at the earliest date at which the Company reasonably determines that the making of such distribution or payment will not cause such violation, as

A-3

required by Treasury Regulation Section 1.409A-2(b)(7)(ii). No payment shall be delayed under this Section 10 if such delay will result in a violation of Section 409A of the Code.

11.No Right to Continued Service. Nothing in the Plan or in this Agreement shall confer upon the Participant any right to continue as an Employee, Consultant, member of the Board, or other service provider of the Company or any Affiliate, or shall interfere with or restrict in any way the rights of the Company or any Affiliate, which are hereby expressly reserved, to discharge the Participant at any time for any reason whatsoever, with or without Cause (as defined in the Employment Agreement), except to the extent expressly provided otherwise in a written agreement between the Participant and the Company or any Affiliate.

12.Severability. In the event that any provision in this Agreement is held invalid or unenforceable, such provision will be severable from, and such invalidity or unenforceability will not be construed to have any effect on, the remaining provisions of this Agreement, which shall remain in full force and effect.

13.Tax Consultation. The Participant understands that he or she may suffer adverse tax consequences in connection with the RSUs and Dividend Equivalents granted pursuant to this Agreement. The Participant represents that the Participant has consulted with any tax consultants that he or she deems advisable in connection with the RSUs and the Dividend Equivalents and that the Participant is not relying on the Company for tax advice.

14.Amendment. This Agreement may only be amended, modified or terminated by a writing executed by the Participant and by a duly authorized representative of the Company.

15.Adjustments. The Participant acknowledges that the RSUs are subject to modification and termination in certain events as provided in this Agreement and Section 11 of the Plan.

16.Relationship to other Benefits.

17.Code Section 409A. To the extent that the Committee determines that any RSUs and/or Dividend Equivalents may not be compliant with or exempt from Code Section 409A, the Committee may amend this Agreement in a manner intended to comply with the requirements of Code Section 409A or an exemption therefrom (including amendments with retroactive effect), or take any other actions as it deems necessary or appropriate to (a) comply with the requirements of Code Section 409A and/or (b) exempt the RSUs and/or the Dividend Equivalents from Code Section 409A and/or preserve the intended tax treatment of the benefits provided with respect to the RSUs. To the extent applicable, this Agreement shall be interpreted in accordance with the provisions of Code Section 409A.

18.Governing Law. The laws of the State of Maryland shall govern the interpretation, validity, administration, enforcement and performance of the terms of this Agreement regardless of the law that might be applied under principles of conflicts of laws.

A-4

19.Captions. Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.

Notwithstanding anything herein to the contrary, the Plan shall be administered, and the RSUs and Dividend Equivalents are granted, only in such a manner as to conform to such laws, rules and regulations. To the extent permitted by applicable law, the Plan and this Agreement shall be deemed amended to the extent necessary to conform to such laws, rules and regulations.

21.Limitations Applicable to Section 16 Persons. Notwithstanding any other provision of the Plan or this Agreement, if the Participant is subject to Section 16 of the Exchange Act, then the Plan, the RSUs and Dividend Equivalents, and this Agreement shall be subject to any additional limitations set forth in any applicable exemptive rule under Section 16 of the Exchange Act (including any amendment to Rule 16b-3 of the Exchange Act) that are requirements for the application of such exemptive rule. To the extent permitted by applicable law, this Agreement shall be deemed amended to the extent necessary to conform to such applicable exemptive rule.

22.Entire Agreement. The Plan and this Agreement (including all exhibits and appendices hereto) constitute the entire agreement of the parties and supersede in their entirety all prior undertakings and agreements of the Company and the Participant with respect to the subject matter hereof. Notwithstanding the foregoing provisions of this Section 22, the Non-Competition, Non-Solicitation and Non-Disclosure Agreement is outside the scope of the foregoing and shall continue in accordance with its terms and conditions.

23.Arbitration. Any dispute or controversy arising under or in connection with this Agreement shall be subject to the provisions of Section 12(c) of the Employment Agreement.

Kilroy Realty Corporation

Employment Agreement for Tyler H. Rose

THIS EMPLOYMENT AGREEMENT by and between KILROY REALTY CORPORATION, a Maryland corporation (the “Company”), Kilroy Realty, L.P., a Delaware limited partnership (the “Operating Partnership”), and Tyler H. Rose (“Executive”) is effective as of January 28, 2016 (the “Effective Date”). This Employment Agreement (this “Agreement”) supersedes and replaces in its entirety Executive’s Employment Agreement, effective as of January 1, 2007 and as amended in December 2008, with the Company and Operating Partnership (the “Prior Employment Agreement”). Rights and obligations of the parties for periods prior to the Effective Date, and any related remedies, shall remain subject to the terms of the Prior Employment Agreement, which shall remain enforceable for that purpose.

W I T N E S S E T H

WHEREAS, the Company desires to continue to employ Executive as Executive Vice President, Chief Financial Officer and Secretary of the Company, and Executive desires to continue in such employment on the terms and conditions herein set forth.

NOW, THEREFORE, in consideration of the foregoing, the mutual covenants contained herein, and other good and valuable consideration, the receipt and adequacy of which the Company and Executive each hereby acknowledge, the Company and Executive hereby agree as follows:

1. Employment.

The Company and Operating Partnership hereby agree to continue to employ Executive as their Executive Vice President, Chief Financial Officer and Secretary, and Executive hereby agrees to accept and continue in such employment during the Term as defined in Section 2 and to serve in such capacities from and after the Effective Date, upon the terms and conditions set forth in this Agreement. The allocation of the rights and obligations between the Company and the Operating Partnership shall be determined by separate agreement of those parties. For purposes of this Agreement, the term “Company” shall be understood to include the Operating Partnership, unless the context otherwise requires.

2. Term.

The term of employment of Executive under this Agreement (the “Term”) shall be the period commencing on the Effective Date and ending on March 1, 2019 and any period of extension thereof in accordance with this Section 2, except that the Term will end at a date, prior to the end of such period or extension thereof, specified in Section 6 or 7 in the event of termination of Executive’s employment. The Term, if not previously ended, shall be extended automatically without further action by either party by one additional year (added to the end of the Term) first on March 1, 2019 (extending the Term to March 1, 2020) and on each succeeding March 1 thereafter, unless either party shall have served written notice in accordance with

Section 13(d) upon the other party at least 90 days before the March 1 extension date electing not to extend the Term further as of that March 1 extension date, in which case employment shall terminate on that March 1 and the Term shall end at that date, subject to earlier termination of employment and earlier termination of the Term in accordance with Section 6 or 7. In the event that Executive’s employment and the Term end pursuant to the preceding sentence as a result of a notice of non-renewal, such termination shall be treated as a termination by the Company pursuant to Section 7(a) below unless Executive qualifies for Retirement (as defined in Section 6(a) below) on the last day of the Term, in which case such termination shall be treated as a Retirement pursuant to Section 6(a) below.

3. Offices and Duties.

The provisions of this Section 3 will apply during the Term:

(a)Generally. Executive shall serve as the Executive Vice President, Chief Financial Officer and Secretary of the Company. Executive shall have and perform such duties, responsibilities, and authorities as are customary for the executive vice president, chief financial officer and secretary of a publicly held corporation of the size, type, and nature of the Company as they may exist from time to time and consistent with such position and status. In addition, if the Company and Executive mutually agree, Executive may serve the Company and its subsidiaries and affiliates in other offices and capacities; provided that, if Executive’s service in any such additional office or capacity ceases, such cessation shall have no effect on the compensation payable hereunder.

(b)Devotion of Time and Effort. Executive shall devote substantially all of his business time and attention, and his best efforts, abilities, experience, and talent, to the positions of Executive Vice President, Chief Financial Officer and Secretary and for the businesses of the Company without commitment to other business endeavors, except that Executive (i) may make personal investments which are not in conflict with his duties to the Company and manage personal and family financial and legal affairs, (ii) may undertake public speaking engagements, and (iii) may serve as a director of (or similar position with) any educational, charitable, community, civic, religious, or similar type of organization, so long as such activities listed in clauses (i) through (iii) do not preclude or render unlawful Executive’s employment or service to the Company or otherwise materially inhibit the performance of Executive’s duties under this Agreement or impair the business of the Company or its subsidiaries.

(c)Place of Employment. Executive’s principal place of employment shall be at the Company’s principal executive offices in Los Angeles, California.

4. Salary and Annual Incentive Compensation.

As partial compensation for the services to be rendered hereunder by Executive, the Company agrees to pay to Executive during the Term the compensation set forth in this Section 4.

(a)Base Salary. The Company will pay to Executive during the Term a base salary at the annual rate of $500,000, payable commencing at the beginning of the Term in accordance with the Company’s usual payroll practices with respect to senior executives (except to the

2

extent deferred under Section 5(c)). Executive’s annual base salary shall be reviewed by the Executive Compensation Committee (the “Committee”) of the Board of Directors of the Company (the “Board”) each year of the Term, beginning in 2016, and may be increased above, but may not be reduced below, the then-current rate of such base salary. For purposes of this Agreement, “Base Salary” means Executive’s then-current base salary.

(b)Annual Incentive Compensation and Equity Awards. During the Term, Executive will be eligible to receive an annual cash award (the “Annual Cash Award”) and annual equity or equity-based awards (the “Annual Stock Incentive”). Executive’s target incentive opportunity for the Annual Cash Award for a particular fiscal year of the Company shall be not less than One Hundred Percent (100%) of Executive’s Base Salary (which target level is referred to as the “Annual Cash Target”). The target grant date fair value (as determined by the Company based on its financial reporting methodology) for the Annual Stock Incentive award(s) granted to Executive for a particular fiscal year of the Company shall be not less than One Hundred Percent (100%) of Executive’s Base Salary (which target level is referred to as the “Annual Stock Target”). The payment and/or vesting requirements applicable to any Annual Cash Award or Annual Stock Incentive will be determined in the Company’s sole discretion, and may include time- and service-based vesting conditions and/or performance-based vesting conditions (which may include corporate, business unit or division, financial, strategic, individual or other objectives). The levels of performance triggering payments of such target Annual Cash Award, and any performance-based conditions applicable to the Annual Stock Incentive, for each year to be established through consultation between the Chief Executive Officer of the Company and the Committee and communicated to Executive during the first quarter of such year by the Committee. The Annual Cash Award may be paid at, and the grant date fair value of the Annual Stock Incentive may be, in the discretion of the Committee, more or less than the annual target incentive opportunity based on actual performance in relation to the target level performance, as determined by the Committee in its sole discretion. In addition, the Committee (or the Board) may determine, in its discretion, to increaseExecutive’s target incentive opportunity or provide an additional incentive opportunity, in excess of the target incentive opportunity, payable for performance in excess of or in addition to the performance required for payment of the target incentive amounts. Any annual incentive compensation payable to Executive shall be paid in accordance with the Company’s usual practices with respect to payment of incentive compensation to senior executives as set forth in Section 5(g) (except to the extent deferred under Section 5(c)).

5. Compensation Plans, Benefits, Deferred Compensation, and Expense Reimbursement.

(a)Executive Compensation Plans. Executive shall be entitled during the Term to participate, without discrimination or duplication, in all executive compensation plans and programs intended for general participation by senior executives of the Company, as presently in effect or as they may be modified or added to by the Company from time to time, subject to the eligibility and other requirements of such plans and programs.

During the Term, Executive shall be eligible to participate in any Outperformance Incentive Award plan (including any similar plan or other substitute plan) that may be adopted by the Board in its sole discretion on terms that are at least as favorable as those made available

3

to other senior executives of the Company in accordance with the terms of the applicable program document.

(b)Employee and Executive Benefit Plans. Executive shall be entitled during the Term to participate, without discrimination or duplication, in all employee and executive benefit plans and programs of the Company, as presently in effect or as they may be modified or added to by the Company from time to time, to the extent such plans are generally available to other senior executives or employees of the Company, subject to the eligibility and other requirements of such plans and programs, including, without limitation, plans providing retirement benefits, medical insurance, life insurance, disability insurance, and accidental death or dismemberment insurance, as well as savings, profit-sharing, 401(k) and stock ownership plans. In addition, Executive shall be eligible to participate in and receive or participate in perquisites under policies implemented by the Board and the Committee. It is understood that no minimum level of perquisites is guaranteed hereunder, and that the Company may make available compensation and benefits to one or more individual executives that will not be deemed “generally available” to senior executives.

In furtherance of and not in limitation of the foregoing, during the Term Executive will participate as Executive Vice President, Chief Financial Officer and Secretary in all executive and employee vacation and time-off programs; provided that Executive shall be entitled to a minimum of five (5) weeks of vacation annually.

(c)Deferral of Compensation. If the Company has in effect or adopts any deferral program or arrangement permitting executives to elect to defer any compensation, Executive will be eligible to participate in such program on terms no less favorable than the terms of participation of any other senior executive officer of the Company. Any plan or program of the Company which provides benefits based on the level of salary, annual incentives, or other compensation of Executive shall, in determining Executive’s benefits, take into account the amount of salary, annual incentives, or other compensation prior to any reduction for voluntary contributions made by Executive under any deferral or similar contributory plan or program of the Company, but shall not treat any payout or settlement under such a deferral or similar contributory plan or program to be additional salary, annual incentives, or other compensation for purposes of determining such benefits, unless otherwise expressly provided under such plan or program.

(d)Reimbursement of Expenses. The Company will promptly reimburse Executive for all reasonable business expenses and disbursements incurred by Executive in the performance of Executive’s duties during the Term in accordance with the Company’s reimbursement policies as in effect from time to time.

(e)Office, Staff and Equipment. The Company agrees to provide to Executive such staff, equipment and office space as is reasonably necessary for Executive to perform his duties hereunder, subject to and on a basis consistent with Company policy on the Effective Date.

(f)Indemnification Agreement. Notwithstanding anything contained in this Agreement to the contrary, the terms and conditions of that certain Indemnification Agreement, dated January 5, 2010, entered into by and between Executive, the Company and the Operating

4

Partnership, as it may be subsequently amended (the “Indemnification Agreement”), shall continue in full force and effect and in accordance with its terms, and nothing in this Agreement shall be construed as superseding or replacing the terms of the Indemnification Agreement.

(g)Limitations Under Code Section 409A.

(i) Anything in this Agreement to the contrary notwithstanding, if (A) on the date of termination of Executive’s employment with the Company or a subsidiary, any of the Company’s stock is publicly traded on an established securities market or otherwise (within the meaning of Section 409A(a)(2)(B)(i) of the Internal Revenue Code, as amended (the “Code”)), (B) Executive is determined to be a “specified employee” within the meaning of Section 409A(a)(2)(B) of the Code, (C) the payments exceed the amounts permitted to be paid pursuant to Treasury Regulations section 1.409A-1(b)(9)(iii) and (D) such delay is required to avoid the imposition of the tax set forth in Section 409A(a)(1) of the Code, as a result of such termination, the Executive would receive any payment that, absent the application of this Section 5(g), would be subject to interest and additional tax imposed pursuant to Section 409A(a) of the Code as a result of the application of Section 409A(2)(B)(i) of the Code, then no such payment shall be payable prior to the date that is the earliest of (1) six (6) months and one day after Executive’s termination date, (2) Executive’s death or (3) such other date (the “Delay Period”) as will cause such payment not to be subject to such interest and additional tax (with a catch-up payment equal to the sum of all amounts that have been delayed to be made as of the date of the initial payment). In particular, with respect to any lump sum payment otherwise required hereunder, in the event of any delay in the payment date as a result of Section 409A(a)(2)(A)(i) and (B)(i) of the Code, the Company will adjust the payments to reflect the deferred payment date by crediting interest thereon at the prime rate in effect at the time such amount first becomes payable, as quoted by the Company’s principal bank.

(ii) To the extent that any benefits to be provided during the Delay Period are considered deferred compensation under Section 409A of the Code provided on account of a “separation from service,” and such benefits are not otherwise exempt from Section 409A of the Code, Executive shall pay the cost of such benefits during the Delay Period, and the Company shall reimburse Executive, to the extent that such costs would otherwise have been paid by the Company or to the extent that such benefits would otherwise have been provided by the Company at no cost to Executive, the Company’s share of the cost of such benefits upon expiration of the Delay Period, and any remaining benefits shall be reimbursed or provided by the Company in accordance with the procedures specified herein.

(iii) In addition, other provisions of this Agreement or any other such plan notwithstanding, the Company shall have no right to accelerate any such payment or to make any such payment as the result of any specific event except to the extent permitted under Section 409A of the Code.

5

(iv) For purposes of Section 409A of the Code, each payment made after termination of employment, including COBRA continuation reimbursement payment, will be considered one of a series of separate payments.

(v) A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Section 409A of the Code and, for purposes of any such provision of this Agreement, references to a “termination,” “termination of employment” or like terms shall mean “separation from service.”

(vi) Any amount that Executive is entitled to be reimbursed under this Agreement that may be treated as taxable compensation will be reimbursed to Executive as promptly as practical and in any event not later than sixty (60) days after the end of the calendar year in which the expenses are incurred; provided that Executive shall have provided a reimbursement request to the Company no later than thirty (30) days prior to the date the reimbursement is due. The amount of the expenses eligible for reimbursement during any calendar year will not affect the amount of expenses for reimbursement in any other calendar year, except as may be required pursuant to an arrangement providing for the reimbursement of expenses referred to in Section 105(b) of the Code.

(vii) The Company shall not be obligated to reimburse Executive for any tax penalty or interest or provide a gross-up in connection with any tax liability of Executive under Section 409A of the Code.

(viii) Any annual bonus that is earned pursuant to Section 4(b) shall be paid, whether in cash or equity as provided above, between January 1 and March 15 of the year following the year for which such annual bonus was earned; provided, however, that if the Board shall determine that it is administratively impracticable, which may include inability of the Company to gain certification of its financial statements, to make such annual bonus payment by March 15, any such payment shall be made as soon as reasonably practicable after such period and in no event later than December 31 of the year following the year for which such annual bonus was earned.

(ix) Whenever a payment under this Agreement specifies a payment period with reference to a number of days (e.g., “payment shall be made within thirty (30) days following the date of termination”), except as specifically provided herein, the actual date of payment within the specified period shall be within the sole discretion of the Company.

(x) Unless this Agreement provides a specified and objectively determinable payment schedule to the contrary, to the extent that any payment of base salary or other compensation is to be paid for a specified continuing period of time beyond the date of termination of Executive’s employment, the payments of such base salary

6

or other compensation shall be made in accordance with the Company’s payroll practices (or other similar term) or, if not payable in accordance with the Company’s payroll practices, on a monthly basis.

6. Termination Due to Retirement, Death, or Disability.

(a)Retirement. Executive may elect to terminate employment hereunder by retirement at or after age 65, or at such earlier age as may be approved by the Board, with at least 30 years of service with the Company (in either case, “Retirement”) upon at least 30 days written notice to the Company. At the time Executive’s employment terminates due to Retirement, the Term will terminate, all obligations of the Company and Executive under Sections 1 through 5 will immediately cease except for obligations which expressly continue after termination of employment due to Retirement, and the Company will pay Executive, and Executive will be entitled to receive, the following:

(i) Executive’s Compensation Accrued at Termination (as defined in Section 8(d));

(ii) In lieu of any annual incentive compensation under Section 4(b) for the year in which Executive’s employment terminated, a Partial Year Bonus (as defined in Section 8(g));

(iii) All equity awards held by Executive at termination that vest based on time shall be fully vested and all other terms of such awards shalt be governed by the plans and programs and the agreements and other documents pursuant to which such awards were granted (subject to Section 11(c) hereof);

(iv) Unless otherwise expressly provided for in an applicable award agreement, any performance objectives upon which the earning of performance-based restricted stock, restricted stock units (“RSUs”), and other equity awards and other long-term incentive awards (including cash awards, but excluding any Outperformance Incentive Award) is conditioned shall be deemed to have been met at the greater of (A) target level at the date of termination, or (B) actual performance and Reasonably Anticipated Performance at the date of termination, and such amounts shall become fully vested and non-forfeitable as a result of termination of employment at the date of such termination, and, in other respects, such awards shall be governed by the plans and programs and the agreements and other documents pursuant to which such awards were granted;

(v) All other rights under any other compensatory or benefit plan, including any deferral under Section 5(c), shall be governed by such plan; and

Such payment shall be in addition to any life insurance payments to which the Executive is otherwise entitled and any other compensation earned by Executive hereunder;

(iv) All equity awards held by Executive at termination that vest based on time shall be fully vested and all other terms of such awards shall be governed by the plans and programs and the agreements and other documents pursuant to which such awards were granted (subject to Section 11(c) hereof);

Subject to Section 5(g), amounts payable under this Section 6 following Executive’s termination of employment will be paid or commence, as applicable, within fifty (50) days following such termination of employment, with the exact date of payment of commencement determined in the sole discretion of the Company.

Executive may terminate his employment hereunder voluntarily for reasons other than Good Reason (as defined in Section 8(f)) at any time upon at least 90 days’ written notice to the Company. An election by Executive not to extend the Term pursuant to Section 2 hereof shall be deemed to be a termination of employment by Executive for reasons other than Good Reason at the date of expiration of the Term. At the time Executive’s employment is terminated by Executive other than for Good Reason, the Term will terminate, all obligations of the Company and Executive under Sections 1 through 5 will immediately cease, and the Company will pay Executive, and Executive will be entitled to the same compensation and rights specified in Section 7(a).

(c)Termination by the Company Without Cause. The Company may terminate the employment of Executive hereunder without Cause upon at least 90 days’ written notice to Executive. At the time Executive’s employment is terminated by the Company (i.e., at the expiration of such notice period), the Term will terminate, all remaining obligations of the Company and Executive under Sections 1 through 5 will immediately cease (except as expressly

11

provided below), and the Company will pay Executive, and Executive will be entitled to receive, the following:

(i) Executive’s Compensation Accrued at Termination;

(iii) In lieu of any annual incentive compensation under Section 4(b) for the year in which Executive’s employment terminates, a Partial Year Bonus (as defined in Section 8(g));

(iv) All equity awards held by Executive at termination which vest based on time shall become vested and all other terms of such awards shall be governed by the plans and programs and the agreements and other documents pursuant to which such awards were granted (subject to Section 11(c) hereof);

(v) Unless otherwise expressly provided for in an applicable award agreement, any performance objectives upon which the earning of performance-based restricted stock, RSUs, and other equity awards and other long-term incentive awards (including cash awards, but excluding any Outperformance Incentive Award) is conditioned shall be deemed to have been met at the greater of (A) target level at the date of termination, or (B) actual performance and Reasonably Anticipated Performance at the date of termination, and such amounts shall become, fully vested and non-forfeitable as a result of termination of employment at the date of such termination, and, in other respects, such awards shall be governed by the plans and programs and the agreements and other documents pursuant to which such awards were granted;

(vi) All deferral arrangements under Section 5(c) will be settled in accordance with the plans and programs governing the deferral;

(vii) All other rights under any other compensatory or benefit plan, including any deferral under Section 5(c), shall be governed by such plan; and

12

and shall cease with continuation coverage for the twenty-fourth (24^th) month following the month in which Executive’s separation from service occurs (or, if earlier, shall cease upon the first to occur of the date Executive becomes eligible for coverage under the health plan of a future employer or the date the Company ceases to offer group medical coverage to its active executive employees). To the extent Executive elects COBRA coverage, Executive shall notify the Company in writing of such election prior to such coverage taking effect and complete any other continuation coverage enrollment procedures the Company may then have in place.

Payments and benefits under this Section 7(c) are subject to Section 5(g). In particular, payments under Sections 7(c)(ii) and (iii) likely will be required under Section 5(g) to be made at the date six months and one day after termination of employment.

(d)Termination by Executive for Good Reason. Executive may terminate his employment hereunder for Good Reason upon 90 days’ written notice to the Company; provided, however, that if the basis for such Good Reason is correctible and the Company has corrected the basis for such Good Reason within 30 days after receipt of such notice, Executive may not then terminate his employment for Good Reason with respect to the matters addressed in the written notice, and therefore Executive’s notice of termination will automatically become null and void. Furthermore, Executive must terminate his employment within 30 days following the failure of the Company to correct the basis for Good Reason within the 30 day period following the Company’s receipt of such notice. At the time Executive’s employment is terminated by Executive for Good Reason, the Term will terminate, all obligations of the Company and Executive under Sections 1 through 5 will immediately cease (except as expressly provided below), and the Company will pay Executive, and Executive will be entitled to receive, the same compensation and rights specified in Section 7(c)(i) - (viii) and the text following clause (viii).

If any payment or benefit under this Section 7(d) is based on Base Salary or other level of compensation or benefits at the time of Executive’s termination and if a reduction in such Base Salary or other level of compensation or benefit was the basis for Executive’s termination for Good Reason, then the Base Salary or other level of compensation in effect before such reduction shall be used to calculate payments or benefits under this Section 7(d).

(e)Other Terms Relating to Certain Terminations of Employment. In the event Executive’s employment terminates for any reason set forth in Section 7(b) through (d), Executive will be entitled to the benefit of any terms of plans or agreements applicable to Executive which are more favorable than those specified in this Section 7 (except without duplication of payments or benefits, including in the case of Annual Incentives in lieu of which amounts are paid hereunder). Except as otherwise provided under Section 5(g), amounts payable under this Section 7 following Executive’s termination of employment will be paid or commence within fifty (50) days following such termination of employment, and, except for the specific payment timing rule provided under Section 11(b) with the exact date of payment or commencement determined in the sole discretion of the Company. The Company shall have no obligation to pay any such amounts or provide any such benefits unless Executive complies with Section 11(b). References to the amount of compensation paid as salary and Annual Incentives

13

in previous years includes payments to Executive by the Company and Operating Partnership in periods prior to the Effective Date.

The Company and the Operating Partnership, and any successor(s) thereto, shall use their commercially reasonable efforts to allow Executive to receive long term capital gain treatment for federal income tax purposes for all interests held by Executive in the Operating Partnership at the time of termination of Executive’s employment (provided, that, nothing herein shall prevent Company from terminating Executive’s employment), and the Company and the Operating Partnership, and any successor(s) thereto, shall reasonably cooperate with Executive to obtain favorable tax treatment for Executive with regard to all interests held by Executive in the Operating Partnership.

10. Rabbi Trust Obligation; Excise Tax-Related Provisions.

(a)Rabbi Trust Funding. In the event of a Change in Control (other than an acquisition resulting in the acquirer being the beneficial owner of less than 50% of the Company’s voting securities), the Company shall, not later than 30 days after the time of such Change in Control, have established one or more rabbi trusts and shall deposit therein cash in an amount sufficient to provide for full payment of all potential cash obligations of the Company that have arisen or would arise as a result such Change in Control and a subsequent termination of Executive’s employment under Section 7(c) or 7(d). Such rabbi trust(s) shall be irrevocable and shall provide that the Company may not, directly or indirectly, use or recover any assets of the trust(s) until such time as all obligations which potentially could arise hereunder have been settled and paid in full, subject only to the claims of creditors of the Company in the event of insolvency or bankruptcy of the Company.

(b)Reduction of Payments If Excise Tax Would Apply. In the event Executive becomes entitled to any amount of benefits payable in connection with a Change in Control or other change in control (whether or not such amounts are payable pursuant to this Agreement) (the “Severance Payments”) and Executive’s receipt of such Severance Payments would cause Executive to become subject to the excise tax (the “Excise Tax”) imposed under Section 4999 of the Code (or any similar federal, state, or local tax that may hereafter be imposed), the Company shall reduce the Severance Payments to the extent necessary to avoid the application of the Excise Tax if, as a result of such reduction, the net benefits to Executive of the Severance Payments as so reduced (after payment of applicable income taxes) exceeds the net benefit to Executive of the Severance Payments without such reduction (after payment of applicable income taxes and excise taxes). Unless Executive shall have given prior written notice specifying a different order to the Company to effectuate the foregoing, the Company shall reduce the Severance Payments by first reducing the portion of the Severance Payments which are not payable in cash and then by reducing or eliminating cash payments, in each case in reverse order beginning with payments or benefits which are to be paid the farthest in time from the Change in Control. Any notice given by the Executive pursuant to the preceding sentence shall take precedence over the provisions of any other plan, arrangement or agreement governing the Executive’s rights and entitlements to any benefits or compensation. The determination that Executive’s Severance Payments would cause him to become subject to the Excise Tax and the calculation of the amount of any reduction, shall be made, at the Company’s discretion, by the Company’s outside auditing firm or by a nationally-recognized accounting or benefits consulting firm designated by the Company prior to a Change in Control. The firm’s expenses shall be paid by the Company.

18

11. Restrictive Covenants; Release of Claims.

(a)Restrictive Covenants. In connection with the entering into of this Agreement, Executive and the Company and the Operating Partnership shall execute a Non-Competition, Non-Solicitation and Non-Disclosure Agreement in the form attached hereto as Exhibit A (the “Non-Competition, Non-Solicitation and Non-Disclosure Agreement”).

Executive agrees, as a condition to receipt of any termination payments and benefits provided for in Sections 6 and 7 herein (other than Compensation Accrued at Termination) (the “Termination Benefits”), that he will execute and not revoke a general release in substantially the form attached hereto as Exhibit B. Such general release shall be provided to Executive within five (5) days of his termination of employment and he shall execute the general release within thirty (30) days and, pursuant to Exhibit B, the revocation period with respect to such release is seven (7) days. In the event the release of claims (and the expiration of any revocation rights provided therein) could become effective in one of two (2) taxable years of Executive depending on when Executive executes and delivers the release, any payment conditioned on execution of the release shall not be made earlier than the first business day of the later of such tax years.

(c)Forfeiture of Outstanding Options and Other Equity Awards. The provisions of Sections 6 and 7 notwithstanding, all options to purchase Stock and other equity awards granted by the Company shall be subject to forfeiture in accordance with the terms of the Non-Competition, Non-Solicitation and Non-Disclosure Agreement.

(d)Survival. The provisions of the Non-Competition, Non-Solicitation and Non-Disclosure Agreement shall survive the termination of the Term and any termination or expiration of this Agreement.

This Agreement is governed by and is to be construed, administered, and enforced in accordance with the laws of the State of California, without regard to conflicts of law principles. If under the governing law, any portion of this Agreement is at any time deemed to be in conflict with any applicable statute, rule, regulation, ordinance, or other principle of law, such portion shall be deemed to be modified or altered to the extent necessary to conform thereto or, if that is not possible, to be omitted from this Agreement. The invalidity of any such portion shall not affect the force, effect, and validity of the remaining portion hereof.

(c)Arbitration. Any dispute or controversy arising under or in connection with this Agreement shall be settled exclusively by arbitration in Los Angeles, California by three arbitrators in accordance with the National Rules for the Resolution of Employment Disputes of the American Arbitration Association in effect at the time of submission to arbitration.

The Company and Executive hereby agree that a judgment upon an award rendered by the arbitrators may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Subject to Section 12(b), the Company shall bear all costs and expenses arising in connection with any arbitration proceeding pursuant to this Section 12. Notwithstanding any provision in this Section 12, Executive shall be paid compensation due and owing under this Agreement during the pendency of any dispute or controversy arising under or in connection with this Agreement.

(d)Interest on Unpaid Amounts. Any amount which has become payable pursuant to the terms of this Agreement or any decision by arbitrators or judgment by a court of law pursuant to this Section 12 but which has not been timely paid shall bear interest at the prime rate in effect at the time such amount first becomes payable, as quoted by the Company’s principal bank.

(e)LIMITATION ON LIABILITIES. IF EITHER EXECUTIVE OR THE COMPANY IS AWARDED ANY DAMAGES AS COMPENSATION FOR ANY BREACH OR ACTION RELATED TO THIS AGREEMENT, A BREACH OF ANY COVENANT CONTAINED IN THIS AGREEMENT (WHETHER EXPRESS OR IMPLIED BY EITHER LAW OR FACT), OR ANY OTHER CAUSE OF ACTION BASED IN WHOLE OR IN PART ON ANY BREACH OF ANY PROVISION OF THIS AGREEMENT, SUCH DAMAGES SHALL BE LIMITED TO CONTRACTUAL AND CONSEQUENTIAL DAMAGES PLUS INTEREST ON ANY DELAYED PAYMENT AT THE MAXIMUM RATE PER ANNUM ALLOWABLE BY APPLICABLE LAW FROM AND AFTER THE DATE(S) THAT SUCH PAYMENTS WERE DUE AND SHALL EXCLUDE PUNITIVE DAMAGES EVEN IF THE RULES REFERRED TO IN SECTION 12(C) WOULD PROVIDE OTHERWISE.

(f)WAIVER OF JURY TRIAL. TO THE EXTENT APPLICABLE, EACH OF THE PARTIES TO THIS AGREEMENT HEREBY AGREES TO WAIVE ITS RESPECTIVE RIGHTS TO A JURY TRIAL FOR ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM

20

RELATING TO THE SUBJECT MATTER OF THIS AGREEMENT. This provision is subject to Section 12(C), requiring arbitration of disputes hereunder.

13. Miscellaneous.

(a)Integration. This Agreement cancels and supersedes any and all prior agreements and understandings (whether written or oral) between the parties hereto with respect to the employment of Executive by the Company, any parent or predecessor company, and the Company’s subsidiaries during the Term, including the Prior Employment Agreement, but excluding (1) existing contracts relating to compensation under executive compensation and employee benefit plans of the Company and its subsidiaries, (2) the Non-Competition, Non-Solicitation and Non-Disclosure Agreement, and (3) the Indemnification Agreement. This Agreement constitutes the entire agreement among the parties with respect to the matters herein provided, and no modification or waiver of any provision hereof shall be effective unless in writing and signed by the parties hereto. Executive shall not be entitled to any payment or benefit under this Agreement which duplicates a payment or benefit received or receivable by Executive under such prior agreements and understandings or under any benefit or compensation plan of the Company.

(b)Successors; Transferability. The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise, and whether or not the corporate existence of the Company continues) to all or substantially all of the business and/or assets of the Company to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. As used in this Agreement, “Company” shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law, or otherwise and, in the case of an acquisition of the Company in which the corporate existence of the Company continues, the ultimate parent company following such acquisition. Subject to the foregoing, the Company may transfer and assign this Agreement and the Company’s rights and obligations hereunder to another entity that is substantially comparable to the Company in its financial strength and ability to perform the Company’s obligations under this Agreement. Neither this Agreement nor the rights or obligations hereunder of the parties hereto shall be transferable or assignable by Executive, except in accordance with the laws of descent and distribution or as specified in Section 13(c).

(c)Beneficiaries. Executive shall be entitled to designate (and change, to the extent permitted under applicable law) a beneficiary or beneficiaries to receive any compensation or benefits provided hereunder following Executive’s death.

(d)Notices. Whenever under this Agreement it becomes necessary to give notice, such notice shall be in writing, signed by the party or parties giving or making the same, and shall be served on the person or persons for whom it is intended or who should be advised or notified, by Federal Express or other similar overnight service or by certified or registered mail, return receipt requested, postage prepaid and addressed to such party at the address set forth below or at such other address as may be designated by such party by like notice:

If to the Company:

KILROY REALTY CORPORATION

Los Angeles, CA 90064

Attention: Corporate Counsel

If to Executive, to the address most recently on file in the payroll records of the Company.

If the parties by mutual agreement supply each other with fax numbers for the purposes of providing notice by facsimile, such notice shall also be proper notice under this Agreement. In the case of Federal Express or other similar overnight service, such notice or advice shall be effective when sent, and, in the cases of certified or registered mail, shall be effective two days after deposit into the mails by delivery to the U.S. Post Office.

(e)Reformation. The invalidity of any portion of this Agreement shall not be deemed to render the remainder of this Agreement invalid.

(f)Headings. The headings of this Agreement are for convenience of reference only and do not constitute a part hereof.

(g)No General Waivers. The failure of any party at any time to require performance by any other party of any provision hereof or to resort to any remedy provided herein or at law or in equity shall in no way affect the right of such party to require such performance or to resort to such remedy at any time thereafter, nor shall the waiver by any party of a breach of any of the provisions hereof be deemed to be a waiver of any subsequent breach of such provisions. No such waiver shall be effective unless in writing and signed by the party against whom such waiver is sought to be enforced

(h)No Obligation To Mitigate. Executive shall not be required to seek other employment or otherwise to mitigate Executive’s damages upon any termination of employment; provided, however, that, to the extent Executive receives from a subsequent employer health or other insurance benefits that are substantially similar to the benefits referred to in Section 5(b) hereof, any such benefits to be provided by the Company to Executive following the Term shall be correspondingly reduced.

(i)Offsets; Withholding. The amounts required to be paid by the Company to Executive pursuant to this Agreement shall not be subject to offset other than with respect to any amounts that are owed to the Company by Executive due to his receipt of funds as a result of his fraudulent activity. The foregoing and other provisions of this Agreement notwithstanding, all payments to be made to Executive under this Agreement, including under Sections 6 and 7, or otherwise by the Company, will be subject to withholding to satisfy required withholding taxes and other required deductions.

(j)Successors and Assigns. This Agreement shall be binding upon and shall inure to the benefit of Executive, his heirs, executors, administrators and beneficiaries, and shall be binding upon and inure to the benefit of the Company and its successors and assigns.

22

(k)Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument.

(l)Due Authority and Execution. The execution, delivery and performance of this Agreement have been duly authorized by the Company and this Agreement represents the valid, legal and binding obligation of the Company, enforceable against the Company according to its terms.

(m)Representations of Executive. Executive represents and warrants to the Company that he has the legal right to enter into this Agreement and to perform all of the obligations on his part to be performed hereunder in accordance with its terms and that he is not a party to any agreement or understanding, written or oral, which prevents him from entering into this Agreement or performing all of his obligations hereunder. In the event of a breach of such representation or warranty on Executive’s part or if there is any other legal impediment which prevents him from entering into this Agreement or performing all of his obligations hereunder, the Company shall have the right to terminate this Agreement forthwith in accordance with the same notice and hearing procedures specified above in respect of a termination by the Company for Cause pursuant to Section 7(a) and shall have no further obligations to Executive hereunder. Notwithstanding a termination by the Company under this Section 13(m), Executive’s obligations under the Non-Competition, Non-Solicitation and Non-Disclosure Agreement shall survive such termination.

14. D&O Insurance.

The Company will maintain directors’ and officers’ liability insurance during the Term and for a period of six years thereafter, covering acts and omissions of Executive during the Term, on terms substantially no less favorable than those in effect on the Effective Date.

NON-COMPETITION, NON-SOLICITATION AND NON-DISCLOSURE AGREEMENT

(See Attached)

NON-COMPETITION, NON-SOLICITATION AND NON-DISCLOSURE AGREEMENT

THIS NON-COMPETITION, NON-SOLICITATION AND NON-DISCLOSURE AGREEMENT (this “Agreement”) is dated as of January 28, 2016, by and among Kilroy Realty Corporation, a Maryland corporation (the “Company”), Kilroy Realty, L.P., a Delaware limited partnership (the “Operating Partnership”), and Tyler H. Rose (“Executive”). Capitalized terms used herein but not otherwise defined herein shall have the meanings ascribed to them in the Employment Agreement (as defined below).

WHEREAS, the Company, the Operating Partnership, and Executive entered into an Employment Agreement, effective as of January 28, 2016 (the “Employment Agreement”), the terms of which superseded that certain Employment Agreement, originally effective as of January 1, 2007 and as amended in December 2008, between the Company, the Operating Partnership and Executive (the “Prior Employment Agreement”); and

WHEREAS, the Company, the Operating Partnership and Executive desire to enter into this Agreement to implement Section11(a) of the Employment Agreement.

NOW, THEREFORE, in furtherance of the foregoing and in exchange for good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, the parties hereto hereby agree as follows:

1.Noncompetition.

(a)At any time during the Period of Employment (as defined below), Executive shall be prohibited from engaging in Competition (as defined below) with the Operating Partnership, the Company or any of their respective subsidiaries and affiliates. For purposes of this Agreement, “Period of Employment” means the period Executive is employed by the Company or any of its affiliates.

(b)The term “Competition” for purposes of this Agreement shall mean the taking of any of the following actions by Executive: (A) conducting, directly or indirectly, real property development, acquisition, sale or management activity if such activity relates to a Material Business (as defined below), whether such business is conducted by Executive individually or as principal, partner, officer, director, consultant, employee, stockholder or manager of any person, partnership, corporation, limited liability company or any other entity; and (B) owning interests in office or industrial real property or other real property which are competitive, directly or indirectly, with any Material Business carried on, directly or through one or more subsidiaries or affiliates or otherwise, by the Operating Partnership or the Company, in the same geographic area.

Notwithstanding the foregoing, the term “Competition” shall be deemed to exclude:

(i)Executive’s ownership of a passive interest in real property;

(ii)Executive participating in the following activities: (a) activities relating to real estate development in geographic regions where none of the Operating Partnership, the Company

or their respective subsidiaries or affiliates are engaged in business; (b) activities involving products (X) which are not competitive, directly or indirectly, with any Material Business carried on by the Operating Partnership, the Company, or any of their respective subsidiaries or affiliates, (Y) with which none of the Operating Partnership, the Company, or their respective subsidiaries or affiliates are involved, and (Z) which do not conflict with any of the activities of the Operating Partnership, the Company, or their respective subsidiaries or affiliates; (c) any activities in which Executive was engaged prior to a Change in Control (as such term is defined in the Company’s 2006 Incentive Award Plan, as it may be amended from time to time) that were not Competition or for which a waiver was granted by the Board; and (d) serving as a director of a for-profit business engaged in the activities described in Section 1(b)(ii)(a) or Section 1(b)(ii)(b); and

(i)Executive becoming a principal, partner, officer, director, consultant, employee, stockholder or manager of any person, partnership, corporation, limited liability company or any other entity, which does not, directly or indirectly, engage in any activity that would be Competition if engaged in by Executive individually.

A “Material Business” is any real property business or segment (e.g., the business of owning, developing, acquiring and/or managing commercial real estate office properties) from which (i) during the preceding 12 months the Operating Partnership and/or the Company derived more than 10% of its revenues (such percentage determined on a pro forma basis for any business acquired during such 12 month period as if the acquisition had occurred at the beginning of such 12 month period), or (ii) it is reasonably expected that the Operating Partnership and/or the Company will derive more than 10% of its revenues during the one (1) year following a Change in Control. Notwithstanding the foregoing, Executive shall have the ability to make investments to protect and maintain his or her tax position for federal income tax purposes in all interests held by Executive in the Operating Partnership at the time of termination of Executive’s employment.

2.Non-Solicitation. Without the consent in writing of the Board, Executive will not, at any time during the Period of Employment and for a period of two (2) years following Executive’s Separation Date (as defined below), acting alone or in conjunction with others, directly or indirectly (i) induce any customers of the Company or any of its affiliates with whom Executive has had contacts or relationships, directly or indirectly, during and within the scope of his or her employment with the Company or any of its affiliates, to curtail or cancel their business with the Company or any such affiliate; (ii) induce, or attempt to influence, any employee of the Company or any of its affiliates to terminate employment; or (iii) solicit or assist any third party in the solicitation of, any person who is an employee of the Company or any affiliate; provided, however, that activities engaged in by or on behalf of the Company are not restricted by this covenant. The provisions of subsections (i), (ii), and (iii) above are separate and distinct commitments independent of each of the other subparagraphs. Notwithstanding anything in this Section 2 to the contrary, Executive is permitted to solicit any individual who served as his or her executive assistant during the Period of Employment. This Section 2 also does not limit any general advertising or job posting not directed at any individual or group of employees of the Company or any of its affiliates. For purposes of this Agreement, “Separation Date” means the date Executive’s employment by the Company or any of its affiliates terminates for any reason (whether with or without cause, voluntarily or involuntarily, or due to death or disability).

2

3.Non-Disclosure; Ownership of Work. Executive shall not, at any time during the Period of Employment or at any time thereafter (including following a termination of Executive’s employment for any reason, whether with or without cause, voluntarily or involuntarily, or due to death or disability), disclose, use, transfer, or sell, except in the course of employment with or other service to the Company, any proprietary information, secrets, organizational or employee information, or other confidential information belonging or relating to the Company and its affiliates and customers so long as such information has not otherwise been disclosed through no wrongdoing of Executive or an individual under a similar restriction or is not otherwise in the public domain, except as required by law or pursuant to legal process. In addition, nothing herein shall preclude Executive from providing truthful information or documents to a government authority with jurisdiction over the Company in connection with an investigation by that authority, or as to a possible violation of applicable law, as long as (i) the information or documents were not obtained through a communication subject to the attorney-client privilege and (ii) such disclosure is required or permitted by law.  The Company encourages Executive, to the extent legally permitted, to give the Company the earliest possible notice of any actual or prospective disclosure to such a government authority or as a result of any legal process. In addition, upon termination of Executive’s employment for any reason, Executive shall return to the Company or its affiliates all documents and other media containing information belonging or relating to the Company or its affiliates. Executive shall promptly disclose in writing to the Company all inventions, discoveries, developments, improvements and innovations (collectively referred to as “Inventions”) that Executive has conceived or made during the Period of Employment; provided, however, that in this context “Inventions” are limited to those which (i) relate in any manner to the existing or contemplated business activities of the Company and its affiliates; (ii) are suggested by or result from Executive’s work at the Company; or (iii) result from the use of the time, materials or facilities of the Company and its affiliates. All Inventions will be the Company’s property rather than Executive’s. Should the Company request it, Executive agrees to sign any document that the Company may reasonably require to establish ownership in any Invention.

4.Cooperation With Regard to Litigation. Executive agrees to cooperate with the Company, during the Period of Employment or at any time thereafter (including following a termination of Executive’s employment for any reason, whether with or without cause, voluntarily or involuntarily, or due to death or disability), by making himself or herself available to testify on behalf of the Company or any subsidiary or affiliate of the Company, in any action, suit, or proceeding, whether civil, criminal, administrative, or investigative, and to assist the Company, or any subsidiary or affiliate of the Company, in any such action, suit, or proceeding, by providing information and meeting and consulting with the Board or its representatives or counsel, or representatives or counsel to the Company, or any subsidiary or affiliate of the Company, as may be reasonably requested and after taking into account Executive’s post-termination responsibilities and obligations. The Company agrees to reimburse Executive, on an after-tax basis, for all reasonable expenses actually incurred in connection with his or her provision of such testimony or assistance as may be requested by the Board or its representatives.

5.Non-Disparagement. Executive shall not, at any time during the Period of Employment or at any time thereafter (including following a termination of Executive’s employment for any reason, whether with or without cause, voluntarily or involuntarily, or due to death or disability) make statements or representations, or otherwise communicate, directly or indirectly, in writing, orally, or otherwise, or take any action which may, directly

3

or indirectly, disparage or be damaging to the Company, its subsidiaries or affiliates or their respective officers, directors, employees, advisors, businesses or reputations, nor shall members of the Board of Directors or the Company’s Chief Executive Officer make any such statements or representations regarding Executive. Notwithstanding the foregoing, nothing in this Agreement shall preclude Executive, members of the Board of Directors, or the Company’s Chief Executive Officer from making truthful statements that are required by applicable law, regulation or legal process.

6.Forfeiture of Outstanding Options and Other Equity Awards. The provisions of Sections 6 and 7 of the Employment Agreement notwithstanding, if Executive fails to comply with the restrictive covenants under Sections 1, 2 or 3 of this Agreement (the date of such failure, the “Noncompliance Date”), all Covered Equity Awards (as defined below) then held by Executive or a transferee of Executive shall be immediately forfeited and thereupon such Covered Equity Awards shall be cancelled. Notwithstanding the foregoing, Executive shall not forfeit any Covered Equity Award unless and until there shall have been delivered to him or her, within six (6) months after the Board (i) had knowledge of conduct or an event allegedly constituting grounds for such forfeiture and (ii) had reason to believe that such conduct or event could be grounds for such forfeiture, a copy of a resolution duly adopted by a majority affirmative vote of the membership of the Board (excluding Executive) at a meeting of the Board called and held for such purpose (after giving Executive reasonable notice specifying the nature of the grounds for such forfeiture and not less than 30 days to correct the acts or omissions complained of, if correctable, and affording Executive the opportunity, together with his or her counsel, to be heard before the Board) finding that, in the good faith opinion of the Board, Executive has engaged in conduct set forth in this Section 6 which constitutes grounds for forfeiture of Executive’s Covered Equity Awards; provided, however, that if any option is exercised or equity award is settled after delivery of such notice, such option or equity award constitutes a Covered Equity Award, and the Board subsequently makes the determination described in this sentence, Executive shall be required to pay to the Company (or the Operating Partnership, as to any Covered Equity Award granted by the Operating Partnership) an amount equal to the difference between the aggregate value of the shares acquired upon such exercise of the option at the date of the Board determination and the aggregate exercise price paid by Executive and an amount equal to the fair market value of the shares delivered in settlement of the equity award at the date of such determination (net of any cash payment for the shares by Executive). Any such forfeiture shall apply to the Covered Equity Awards notwithstanding any term or provision of any applicable award agreement. In addition, Executive agrees that all compensation paid or payable to Executive shall be subject to (i) the provisions of the Company’s claw-back policy as in effect on the Effective Date, and (ii) any claw-back required by applicable law. For purposes of this Agreement, a “Covered Equity Award” means a stock option, restricted stock, stock unit, performance unit, profit interest, or other equity award that was granted to Executive by the Company or the Operating Partnership after the date that is three years before the Noncompliance Date at issue.

7.Remedies; Waiver of Jury Trial. Executive agrees that any breach of the terms of this Agreement would result in irreparable injury and damage to the Company for which the Company would have no adequate remedy at law. Executive therefore also agrees that in the event of said breach or any threat of breach, and notwithstanding Section12 of the Employment

4

Agreement, the Company shall be entitled to an immediate injunction and restraining order from a court of competent jurisdiction to prevent such breach and/or threatened breach and/or continued breach by Executive and/or any and all persons and/or entities acting for and/or with Executive, without having to prove damages. The availability of injunctive relief shall be in addition to any other remedies to which the Company may be entitled at law or in equity, but remedies other than injunctive relief may only be pursued in an arbitration brought in accordance with Section12 of the Employment Agreement. The terms of this paragraph shall not prevent the Company from pursuing in an arbitration any other available remedies for any breach or threatened breach of this Agreement, including but not limited to the recovery of damages from Executive. Executive, the Operating Partnership, and the Company agree to waive their rights to a jury trial for any claim or cause of action based upon or arising out of this Agreement or any dealings between them relating to the subject matter of this Agreement.

Executive hereby further agrees that, if it is ever determined, in an arbitration brought in accordance with Section12 of the Employment Agreement, that willful actions by Executive have constituted wrongdoing that contributed to any material misstatement or omission from any report or statement filed by the Company with the U.S. Securities and Exchange Commission or material fraud against the Company, then the Company, or its successor, as appropriate, may recover all of any award or payment made to Executive, less the amount of any net tax owed by Executive with respect to such award or payment over the tax benefit to Executive from the repayment or return of the award or payment, pursuant to Section 7(c) or (d) of the Employment Agreement, and Executive agrees to repay and return such awards and amounts to the Company within 30 calendar days of receiving notice from the Company that the Board has made the determination referenced above and accordingly the Company is demanding repayment pursuant to this Section 7. The Company or its successor may, in its sole discretion, affect any such recovery by (i) obtaining repayment directly from Executive; (ii) setting off the amount owed to it against any amount or award that would otherwise be payable by the Company to Executive; or (iii) any combination of (i) and (ii) above.

8.Attorneys’ Fees. If any legal action, arbitration or other proceeding is brought for the enforcement of this Agreement, or because of an alleged dispute, breach or default in connection with any of the provisions of this Agreement, the prevailing party shall be entitled to recover reasonable attorneys’ fees and other costs incurred in that action or proceeding, including any appeal of such action or proceeding, in addition to any other relief to which that party may be entitled.

9.Survival. This Agreement shall survive the termination of Executive’s employment and the assignment of this Agreement by the Operating Partnership or the Company to any successor to their respective business as provided in Section 13.

10.Severability. Any provision of this Agreement which is deemed invalid, illegal or unenforceable in any jurisdiction shall, as to that jurisdiction and subject to this paragraph, be ineffective to the extent of such invalidity, illegality or unenforceability, without affecting in any way the remaining provisions hereof in such jurisdiction or rendering any other provisions of this Agreement invalid, illegal or unenforceable in any other jurisdiction. If any covenant should be deemed invalid, illegal or unenforceable because its scope is considered excessive, such

5

covenant shall be modified so that the scope of the covenant is reduced only to the minimum extent necessary to render the modified covenant valid, legal and enforceable.

11.Governing Law and Venue. This Agreement shall be governed, construed, interpreted and enforced in accordance with the laws of the State of California, without regard to the conflict of laws principles thereof. Executive expressly consents to personal jurisdiction and venue in the state and federal courts (a) for the county in which the principal place of the Operating Partnership’s business is located for any lawsuit filed there against Executive by the Operating Partnership arising from or related to this Agreement, or (b) for the county in which the principal place of the Company’s business is located for any lawsuit filed there against Executive by the Company arising from or related to this Agreement.

12.Entire Agreement. Subject to Section 3(b) of the Employment Agreement, this Agreement contains the entire agreement and understanding between the Operating Partnership, the Company and Executive with respect to the subject matter hereof, and supersedes all prior agreements and understandings with respect to the subject matter hereof (including, without limitation, the Prior Employment Agreement), and the parties hereto have made no representations, promises, agreements or understandings, written or oral, relating to the subject matter of this Agreement which are not set forth herein. This Agreement shall not be changed unless in writing and signed by both Executive and an authorized representative of the Operating Partnership and the Company. Notwithstanding anything contained in this Agreement to the contrary, nothing in this Agreement shall be construed as superseding or replacing the terms of (1) the Employment Agreement or (2) that certain Indemnification Agreement, dated January 5, 2010, entered into by and between Executive, the Company and the Operating Partnership, as it may be subsequently amended.

13.Assignment. This Agreement may not be assigned by Executive, but may be assigned by the Operating Partnership and the Company to any successor to their respective business and will inure to the benefit of and be binding upon any such successor.

14.Notice. Whenever under this Agreement it becomes necessary to give notice, such notice shall be in writing, signed by the party or parties giving or making the same, and shall be served on the person or persons for whom it is intended or who should be advised or notified, by Federal Express or other similar overnight service or by certified or registered mail, return receipt requested, postage prepaid and addressed to such party at the address set forth below or at such other address as may be designated by such party by like notice.

15.Waiver. Any waiver or failure to enforce any provision of this Agreement on one occasion will not be deemed a waiver of that provision or any other provision on any other occasion.

17.Executive’s Acknowledgment.

FORM OF RELEASE

1.Release by the Executive. For and in consideration of the payments and other benefits due to Tyler H. Rose (the “Executive”) pursuant to the Employment Agreement dated as of January 28, 2016 (the “Agreement”), by and between Kilroy Realty Corporation, (the “Company”), Kilroy Realty, L.P. and the Executive, and for other good and valuable consideration, the Executive hereby agrees, for the Executive, the Executive’s spouse and child or children (if any), the Executive’s heirs, beneficiaries, devisees, executors, administrators, attorneys, personal representatives, successors and assigns, to forever release, discharge and covenant not to sue the Company, or any of its divisions, affiliates, subsidiaries, parents, branches, predecessors, successors, assigns, and, with respect to such entities, their officers, directors, trustees, employees, agents, shareholders, administrators, general or limited partners, representatives, attorneys, insurers and fiduciaries, past, present and future (the “Released Parties”) from any and all claims of any kind arising out of, or related to, his employment with the Company, its affiliates and subsidiaries (collectively, with the Company, the “Affiliated Entities”) or the Executive’s separation from employment with the Affiliated Entities, which the Executive now has or may have against the Released Parties, whether known or unknown to the Executive, by reason of facts which have occurred on or prior to the date that the Executive has signed this Release.

2.Acknowledgment of Payment of Wages. Except for accrued vacation (which the parties agree totals approximately [____] days of pay) and salary for the current pay period, the Executive acknowledges that he or she has received all amounts owed for his or her regular and usual salary (including, but not limited to, any bonus, severance, or other wages), and usual benefits through the date of this Release.

3.Waiver of Civil Code Section 1542. THE EXECUTIVE ACKNOWLEDGES THAT THE EXECUTIVE HAS BEEN ADVISED OF AND IS FAMILIAR WITH THE PROVISIONS OF CALIFORNIA CIVIL CODE SECTION 1542, WHICH PROVIDES AS FOLLOWS:

BEING AWARE OF SAID CODE SECTION, THE EXECUTIVE HEREBY EXPRESSLY WAIVES ANY RIGHTS HE MAY HAVE THEREUNDER, AS WELL AS UNDER ANY OTHER STATUTES OR COMMON LAW PRINCIPLES OF SIMILAR EFFECT.

The Executive also understands that the Executive has a period of seven (7) days after signing this Release within which to revoke his agreement, and that neither the Company nor any other person is obligated to make any payments or provide any other benefits to the Executive pursuant to the Agreement until eight (8) days have passed since the Executive’s signing of this Release without the Executive’s signature having been revoked other than any accrued obligations or other benefits payable pursuant to the terms of the Company’s normal payroll practices or employee benefit plans. In the event the Executive exercises this right of revocation, neither the Company nor the Executive will have any obligations under this Release.

In addition, this Release does not cover any claim that cannot be so released as a matter of applicable law. Notwithstanding anything to the contrary herein, nothing in this Release prohibits the Executive from filing a charge with or participating in an investigation conducted by any state or federal government agencies. The Executive does waive, however, the right to receive any monetary or other recovery, should any agency or any other person pursue any claims on the Executive’s behalf arising out of any claim released pursuant to this Release. The Executive acknowledges and agrees that the Executive has received any and all leave and other benefits that the Executive has been and is entitled to pursuant to the Family and Medical Leave Act of 1993.

Exhibit 10.3

January 28, 2016    

Justin W. Smart

12200 West Olympic Boulevard, Suite 200

Los Angeles, CA 90064

Dear Justin,

This letter sets forth the terms of our agreement relative to your continued employment with Kilroy Realty Corporation, a Maryland corporation (the “Company”), and Kilroy Realty, L.P., a Delaware limited partnership (the “Operating Partnership”). This letter shall be effective as of the date hereof (the “Effective Date”) and, as of the Effective Date, supersedes and replaces in its entirety that certain letter agreement, originally dated as of July 20, 2007 and as amended in December 2008, between you, the Company and the Operating Partnership (the “Prior Employment Agreement”), and all other prior employment agreements with the Company and/or the Operating Partnership.

1. Position/Title: Executive Vice President-Development and Construction Services

2. Term: Effective as of the Effective Date and ending March 1, 2019, and automatically extended on March 1, 2019 and each March 1 thereafter for an additional 12 month term unless either the Company or you provides notice to the other party at least 90 days before the March 1 extension date electing not to extend the Term further as of that March 1.

3. Base Salary: During the Term, the Company will pay you a base salary at the annual rate of $500,000. Your annual base salary shall be reviewed by the Executive Compensation Committee of the board of directors of the Company (the “Board”) each year of the Term, beginning in 2016, and may be increased above, but may not be reduced below, thethen-current rate of such base salary.

4. Bonus and

Equity Awards: An annual cash award (the “Annual Cash Award”) and annual equity or equity-based awards (the “Annual Stock Incentive”) (collectively, the “Annual Incentives”). The annual target incentive opportunity for the Annual Cash Award for a particular fiscal year of the Company shall be not less than One Hundred Percent (100%) of the base salary paid to you by the Company for that fiscal year. The target grant date fair value (as determined by the Company based on its financial reporting methodology)

for the Annual Stock Incentive award(s) granted to you for a particular fiscal year of the Company shall be not less than One Hundred Percent (100%) of your annual rate of base salary in effect on the date of grant (the “Annual Stock Target”). The payment and/or vesting requirements applicable to any Annual Cash Award or Annual Stock Incentive will be determined in the Company’s sole discretion, and may include time- and service-based vesting conditions and/or performance-based vesting conditions (which may include corporate, business unit or division, financial, strategic, individual or other objectives). In each case, the applicable target amount may be increased by the Company. Any Annual Cash Award earned pursuant to this Section 4 shall be paid between January 1 and March 15 of the year following the year for which such Annual Cash Award was earned; provided, however, that if the Board shall determine that it is administratively impracticable, which may include inability of the Company to gain certification of its financial statements, to make such Annual Cash Award payment by March 15, any such payment shall be made as soon as reasonably practicable after such period and in no event later than December 31 of the year following the year for which such Annual Cash Award was earned.

5. Benefits: All employee and executive benefit plans and programs of the Company, as presently in effect or as they may be modified or added to by the Company from time to time, to the extent such plans are generally available to other senior executives or employees of the Company, subject to the eligibility and other requirements of such plans and programs.

6. Vacation: 5 weeks per year

7. Severance: If employment is terminated for reasons other than (i) Cause, (ii) by you other than for Good Reason or (iii) the end of the Term of this Agreement, you shall receive severance payments equal to:

• Compensation accrued at termination;

• A single severance payment in cash on or as soon as practicable after the first day after the release described in Section 10 becomes irrevocable in accordance with its terms (but in no event later than March 15 of the year following the year in which the termination of employment occurs), in an aggregate amount equal to the sum of: (i) two times Base Salary plus (ii) two times the average of the two highest Annual Incentives received by you during the preceding three completed performance years, provided that the Annual Stock Target provided for in this agreement instead of the actual Annual Stock Incentive shall be used in the calculation of the severance payment; provided, however, if employment is terminated by reason of death,

2

your severance payment will be one times Base Salary and your average Annual Incentive;

• In lieu of any Annual Cash Award compensation a partial year bonus based on actual performance against bonus targets as of the date of termination, payable within the time period set forth in Section 4 above;

• All equity awards held by you at termination which vest based on time shall become fully vested and all other terms of such awards shall be governed by the plans and programs and the agreements and other documents pursuant to which such awards were granted;

• Unless otherwise expressly provided for in an applicable award agreement, any performance objectives upon which the earning of performance-based restricted stock, RSUs, and other equity awards and other long-term incentive awards (including cash awards) is conditioned shall be deemed to have been met at the greater of (A) target level at the date of termination, or (B) actual performance and reasonably anticipated performance at the date of termination, and such amounts shall become fully vested and non-forfeitable as a result of termination of employment at the date of such termination, and, in other respects, such awards shall be governed by the plans and programs and the agreements and other documents pursuant to which such awards were granted;

• All other rights under any other compensatory or benefit plan, including any deferrals, shall be governed by such plan; and

• The Company will pay or reimburse you for your premiums charged to continue medical coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act (“COBRA”), at the same or reasonably equivalent medical coverage for you (and, if applicable, your eligible dependents) as in effect immediately prior to the date your employment terminates, to the extent that you elect such continued coverage; provided that the Company’s obligation to make any payment or reimbursement pursuant to this section shall, subject to Section 14 of this Agreement, commence with continuation coverage for the month following the month in which your “separation from service” (as defined in Section 14 of this Agreement) occurs and shall cease with continuation coverage for the twenty-fourth (24^th) month (or, if your employment terminates due to your death or disability, the twelfth (12^th) month) following the month in which your separation from service occurs (or, if earlier, shall cease upon the first to occur of the date you become eligible for coverage under the health plan of a future employer or the date the Company ceases to offer group medical coverage to its active executive employees). To the extent you elect COBRA coverage, you shall notify the Company in writing of such election prior to such coverage taking effect and complete any

3

other continuation coverage enrollment procedures the Company may then have in place.

8. Cause: If employment terminates due to Cause, you will receive your compensation accrued through the date of termination and no additional amounts other than what you are entitled to pursuant to the terms of any Company benefit plans.

For purposes of this Agreement, “Cause” shall mean:

• conviction for commission of a felony or a crime involving moral turpitude;

• willful commission of any act of theft, fraud, embezzlement or misappropriation against the Company or its subsidiaries or affiliates; or

• willful and continued failure to substantially perform your duties (other than such failure resulting from your incapacity due to physical or mental illness), which failure is not remedied within 30 calendar days after written demand for substantial performance is delivered by the Company which specifically identifies the manner in which the Company believes that you have not substantially performed your duties.

No act, or failure to act, on the part of you shall be deemed “willful” unless done, or omitted to be done, by you not in good faith and without reasonable belief that your action or omission was in the best interest of the Company.

9. Good Reason: For purposes of this Agreement, “Good Reason” shall mean, without your express written consent, the occurrence of any of the following circumstances unless, if correctable, such circumstances are fully corrected within 30 days of the notice of termination given in respect thereof which notice must be given within 90 days of the occurrence:

• the assignment of duties materially inconsistent with your position and status hereunder, or an alteration, materially adverse to you, in the nature of your duties, responsibilities, and authorities, your positions or the conditions of your employment;

• on or after a change in control (A) a material reduction by the Company in your Base Salary, (B) the setting of your annual target incentive opportunities or payment of earned Annual Incentives in amounts materially less than specified above or (C) a material adverse change in benefits;

4

• the failure of the Company to obtain a satisfactory agreement from any successor to the Company to fully assume the Company’s obligations and to perform under this Agreement; or

• any other failure by the Company to perform any material obligation under, or breach by the Company of any material provision of, this Agreement.

Notwithstanding the foregoing, you will not be entitled to any of the termination payments or benefits provided in Section 7 as a result of a termination of your employment by you for Good Reason unless such termination becomes effective within 90 days following the expiration of the 30 day cure period described above.

10. Release of

Claims: You agree as a condition to receipt of any termination payments and benefits provided for in Section 7 herein, that you will execute and not revoke a general release in substantially the form attached hereto as Exhibit A. Such general release shall be provided to you within three (3) days of the date of your termination of employment and you shall execute the general release within 21 days and, pursuant to Exhibit A, the revocation period with respect to such release is 7 days. In the event the release of claims (and the expiration of any revocation rights provided therein) could become effective in one of two (2) of your taxable years depending on when you execute and deliver the release, any payment conditioned on execution of the release shall not be made earlier than the first business day of the later of such tax years.

11. Covenants: In connection with the entering into of this Agreement, you and the Company shall enter into the Non-Competition, Non-Solicitation and Non-Disclosure Agreement in the form attached hereto as Exhibit B (the “Non-Competition, Non-Solicitation and Non-Disclosure Agreement”).

12. WAIVER OF

JURY TRIAL: TO THE EXTENT APPLICABLE, EACH OF THE PARTIES TO THIS AGREEMENT HEREBY AGREES TO WAIVE ITS RESPECTIVE RIGHTS TO A JURY TRIAL FOR ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS AGREEMENT.

13. Governing Law/

Arbitration: This Agreement is governed by and is to be construed, administered, and enforced in accordance with the laws of the State of California, without regard to conflicts of law principles. Any dispute or controversy arising under or in connection with this Agreement shall be settled exclusively by

5

arbitration in Los Angeles, California by three arbitrators in accordance with the National Rules for the Resolution of Employment Disputes of the American Arbitration Association in effect at the time of submission to arbitration. Judgment may be entered on the arbitrators’ award in any court having jurisdiction. For purposes of entering any judgment upon an award rendered by the arbitrators, the Company and you hereby consent to the jurisdiction of any or all of the following courts: (i) the United States District Court for the Southern District of California, (ii) any of the courts of the State of California, or (iii) any other court having jurisdiction. The Company and you further agree that any service of process or notice requirements in any such proceeding shall be satisfied if the rules of such court relating thereto have been substantially satisfied. The Company and you hereby waive, to the fullest extent permitted by applicable law, any objection which it may now or hereafter have to such jurisdiction and any defense of inconvenient forum. The Company and you hereby agree that a judgment upon an award rendered by the arbitrators may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

14. Section 409A: (i)    Anything in this Agreement to the contrary notwithstanding, to the maximum extent permitted by applicable law, amounts payable to you pursuant to Section 7 shall be made in reliance upon Treas. Reg. Section 1.409A-1(b)(9) (Separation Pay Plans) or Treas. Reg.Section 1.409A-1(b)(4) (Short-Term Deferrals). However, if (A) on the date of termination of your employment with the Company or a subsidiary, any of the Company’s stock is publicly traded on an established securities market or otherwise (within the meaning of Section 409A(a)(2)(B)(i) of the Internal Revenue Code, as amended (the “Code”)), (B) you are determined to be a “specified employee” within the meaning of Section 409A(a)(2)(B) of the Code, (C) the payments exceed the amounts permitted to be paid pursuant to Treasury Regulations Section 1.409A-1(b)(9)(iii), if applicable and (D) such delay is required to avoid the imposition of the tax set forth in Section 409A(a)(1) of the Code, as a result of such termination, you would receive any payment that, absent the application of this Section 14(i), would be subject to interest and additional tax imposed pursuant to Section 409A(a) of the Code as a result of the application of Section 409A(2)(B)(i) of the Code, then no such payment shall be payable prior to the date that is the earliest of (1) six (6) months and one day after your termination date, (2) your death or (3) such other date (the “Delay Period”) as will cause such payment not to be subject to such interest and additional tax (with a catch-up payment equal to the sum of all amounts that have been delayed to be made as of the date of the initial payment). In particular, with respect to any lump sum payment otherwise required hereunder, in the event of any delay in the payment date as a result of Code Section 409A(a)(2)(A)(i) and (B)(i), the Company will adjust the

6

payments to reflect the deferred payment date by crediting interest thereon at the prime rate in effect at the time such amount first becomes payable, as quoted by the Company’s principal bank.

(ii)    To the extent that any benefits to be provided during the Delay Period are considered deferred compensation under Code Section 409A provided on account of a “separation from service,” and such benefits are not otherwise exempt from Code Section 409A, the Executive shall pay the cost of such benefits during the Delay Period, and the Company shall reimburse the Executive, to the extent that such costs would otherwise have been paid by the Company or to the extent that such benefits would otherwise have been provided by the Company at no cost to the Executive, the Company’s share of the cost of such benefits upon expiration of the Delay Period, and any remaining benefits shall be reimbursed or provided by the Company in accordance with the procedures specified herein.

(iii)    In addition, other provisions of this Agreement or any other such plan notwithstanding, the Company shall have no right to accelerate any such payment or to make any such payment as the result of any specific event except to the extent permitted under Section 409A.

(iv)    For purposes of Section 409A of the Code, each payment made after termination of employment, including each health insurance continuation payment or reimbursement, will be considered one of a series of separate payments.

(v)    To the extent any cash payments to be made to you upon a termination of your employment would be deemed to be nonqualified deferred compensation under Code Section 409A, then with respect to such cash payments, a termination of employment shall not be deemed to have occurred unless such termination is also a “separation from service” within the meaning of Section 409A of the Code and for purposes of any such provision of this Agreement with respect to such cash payments, references to a “termination,” “termination of employment” or like terms shall mean “separation from service.”

(vi)    Any amount that you are entitled to be reimbursed under this Agreement that may be treated as taxable compensation will be reimbursed to you as promptly as practical and in any event not later than sixty (60) days after the end of the calendar year in which the expenses are incurred; provided, that, you shall have provided a reimbursement request to the Company no later than thirty (30) days prior to the date the reimbursement is due. The amount of the expenses eligible for reimbursement during any calendar year will not affect the amount of expenses eligible for reimbursement in any other calendar year, except as

7

may be required pursuant to an arrangement providing for the reimbursement of expenses referred to in Section 105(b) of the Code.

(vii)    The Company shall not be obligated to reimburse you for any tax penalty or interest or provide a gross-up in connection with any tax liability you may incur under Section 409A of the Code.

(viii)    Whenever a payment under this Agreement specifies a payment period with reference to a number of days (e.g., “payment shall be made within thirty (30) days following the date of termination”), the actual date of payment within the specified period shall be within the sole discretion of the Company.

(ix)    Unless this Agreement provides a specified and objectively determinable payment schedule to the contrary, to the extent that any payment of base salary or other compensation is to be paid for a specified continuing period of time beyond the date of termination of Executive’s employment in accordance with the Company’s payroll practices (or other similar term), the payments of such base salary or other compensation shall be made on a monthly basis.

15. Integration: This Agreement cancels and supersedes any and all prior agreements and understandings (whether written or oral) between the parties hereto with respect to your employment by the Company, any parent or predecessor company, and the Company’s subsidiaries during the Term, including the Prior Employment Agreement, but excluding (1) existing written contracts relating to compensation under equity compensation and employee benefit plans of the Company and its subsidiaries, and (2) the Non-Competition, Non-Solicitation and Non-Disclosure Agreement.

3.Waiver of Civil Code Section 1542. THE EXECUTIVE ACKNOWLEDGES THAT THE EXECUTIVE HAS BEEN ADVISED OF AND IS FAMILIAR WITH THE PROVISIONS OF CALIFORNIA CIVIL CODE SECTION 1542, WHICH PROVIDES AS FOLLOWS:

2

FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH, IF KNOWN BY HIM OR HER, MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.”

BEING AWARE OF SAID CODE SECTION, THE EXECUTIVE HEREBY EXPRESSLY WAIVES ANY RIGHTS HE MAY HAVE THEREUNDER, AS WELL AS UNDER ANY OTHER STATUTES OR COMMON LAW PRINCIPLES OF SIMILAR EFFECT.

4.ADEA Waiver.

The Executive also understands that the Executive has a period of seven (7) days after signing this Release within which to revoke his agreement, and that neither the Company nor any other person is obligated to make any payments or provide any other benefits to the Executive pursuant to the Agreement until eight (8) days have passed since the Executive’s signing of this Release without the Executive’s signature having been revoked other than any accrued obligations or other benefits payable pursuant to the terms of the Company’s normal payroll practices or employee benefit plans. In the event the Executive exercises this right of revocation, neither the Company nor the Executive will have any obligations under this Release.

3

The Executive acknowledges and agrees that the Executive has received any and all leave and other benefits that the Executive has been and is entitled to pursuant to the Family and Medical Leave Act of 1993.

6.No Transferred Claims. The Executive represents and warrants to the Company that the Executive has not heretofore assigned or transferred to any person not a party to this Release any released matter or any part or portion thereof.

7.Miscellaneous. The following provisions shall apply for purposes of this Release:

(See attached)

NON-COMPETITION, NON-SOLICITATION AND NON-DISCLOSURE AGREEMENT

THIS NON-COMPETITION, NON-SOLICITATION AND NON-DISCLOSURE AGREEMENT (this “Agreement”) is dated as of January 28, 2016, by and among Kilroy Realty Corporation, a Maryland corporation (the “Company”), Kilroy Realty, L.P., a Delaware limited partnership (the “Operating Partnership”), and Justin W. Smart (“Executive”). Capitalized terms used herein but not otherwise defined herein shall have the meanings ascribed to them in the Employment Agreement (as defined below).

WHEREAS, the Company, the Operating Partnership, and Executive entered into a letter agreement, effective as of January 28, 2016 (the “Employment Agreement”), the terms of which superseded that certain letter agreement, originally effective as of July 20, 2007 and as amended in December 2008, between the Company, the Operating Partnership and Executive (the “Prior Employment Agreement”); and

WHEREAS, the Company, the Operating Partnership and Executive desire to enter into this Agreement to implement Section 11 of the Employment Agreement.

NOW, THEREFORE, in furtherance of the foregoing and in exchange for good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, the parties hereto hereby agree as follows:

1.Noncompetition.

(a)At any time during the Period of Employment (as defined below), Executive shall be prohibited from engaging in Competition (as defined below) with the Operating Partnership, the Company or any of their respective subsidiaries and affiliates. For purposes of this Agreement, “Period of Employment” means the period Executive is employed by the Company or any of its affiliates.

(b)The term “Competition” for purposes of this Agreement shall mean the taking of any of the following actions by Executive: (A) conducting, directly or indirectly, real property development, acquisition, sale or management activity if such activity relates to a Material Business (as defined below), whether such business is conducted by Executive individually or as principal, partner, officer, director, consultant, employee, stockholder or manager of any person, partnership, corporation, limited liability company or any other entity; and (B) owning interests in office or industrial real property or other real property which are competitive, directly or indirectly, with any Material Business carried on, directly or through one or more subsidiaries or affiliates or otherwise, by the Operating Partnership or the Company, in the same geographic area.

Notwithstanding the foregoing, the term “Competition” shall be deemed to exclude:

(i)Executive’s ownership of a passive interest in real property;

(ii)Executive participating in the following activities: (a) activities relating to real estate development in geographic regions where none of the Operating Partnership, the Company

or their respective subsidiaries or affiliates are engaged in business; (b) activities involving products (X) which are not competitive, directly or indirectly, with any Material Business carried on by the Operating Partnership, the Company, or any of their respective subsidiaries or affiliates, (Y) with which none of the Operating Partnership, the Company, or their respective subsidiaries or affiliates are involved, and (Z) which do not conflict with any of the activities of the Operating Partnership, the Company, or their respective subsidiaries or affiliates; (c) any activities in which Executive was engaged prior to a Change in Control (as such term is defined in the Company’s 2006 Incentive Award Plan, as it may be amended from time to time) that were not Competition or for which a waiver was granted by the Board; and (d) serving as a director of a for-profit business engaged in the activities described in Section 1(b)(ii)(a) or Section 1(b)(ii)(b); and

(iii)Executive becoming a principal, partner, officer, director, consultant, employee, stockholder or manager of any person, partnership, corporation, limited liability company or any other entity, which does not, directly or indirectly, engage in any activity that would be Competition if engaged in by Executive individually.

A “Material Business” is any real property business or segment (e.g., the business of owning, developing, acquiring and/or managing commercial real estate office properties) from which (i) during the preceding 12 months the Operating Partnership and/or the Company derived more than 10% of its revenues (such percentage determined on a pro forma basis for any business acquired during such 12 month period as if the acquisition had occurred at the beginning of such 12 month period), or (ii) it is reasonably expected that the Operating Partnership and/or the Company will derive more than 10% of its revenues during the one (1) year following a Change in Control. Notwithstanding the foregoing, Executive shall have the ability to make investments to protect and maintain his or her tax position for federal income tax purposes in all interests held by Executive in the Operating Partnership at the time of termination of Executive’s employment.

2.Non-Solicitation. Without the consent in writing of the Board, Executive will not, at any time during the Period of Employment and for a period of two (2) years following Executive’s Separation Date (as defined below), acting alone or in conjunction with others, directly or indirectly (i) induce any customers of the Company or any of its affiliates with whom Executive has had contacts or relationships, directly or indirectly, during and within the scope of his or her employment with the Company or any of its affiliates, to curtail or cancel their business with the Company or any such affiliate; (ii) induce, or attempt to influence, any employee of the Company or any of its affiliates to terminate employment; or (iii) solicit or assist any third party in the solicitation of, any person who is an employee of the Company or any affiliate; provided, however, that activities engaged in by or on behalf of the Company are not restricted by this covenant. The provisions of subsections (i), (ii), and (iii) above are separate and distinct commitments independent of each of the other subparagraphs. Notwithstanding anything in this Section 2 to the contrary, Executive is permitted to solicit any individual who served as his or her executive assistant during the Period of Employment. This Section 2 also does not limit any general advertising or job posting not directed at any individual or group of employees of the Company or any of its affiliates. For purposes of this Agreement, “Separation Date” means the date Executive’s employment by the Company or any of its affiliates terminates for any reason (whether with or without cause, voluntarily or involuntarily, or due to death or disability).

2

3.Non-Disclosure; Ownership of Work. Executive shall not, at any time during the Period of Employment or at any time thereafter (including following a termination of Executive’s employment for any reason, whether with or without cause, voluntarily or involuntarily, or due to death or disability), disclose, use, transfer, or sell, except in the course of employment with or other service to the Company, any proprietary information, secrets, organizational or employee information, or other confidential information belonging or relating to the Company and its affiliates and customers so long as such information has not otherwise been disclosed through no wrongdoing of Executive or an individual under a similar restriction or is not otherwise in the public domain, except as required by law or pursuant to legal process. In addition, nothing herein shall preclude Executive from providing truthful information or documents to a government authority with jurisdiction over the Company in connection with an investigation by that authority, or as to a possible violation of applicable law, as long as (i) the information or documents were not obtained through a communication subject to the attorney-client privilege and (ii) such disclosure is required or permitted by law.  The Company encourages Executive, to the extent legally permitted, to give the Company the earliest possible notice of any actual or prospective disclosure to such a government authority or as a result of any legal process. In addition, upon termination of Executive’s employment for any reason, Executive shall return to the Company or its affiliates all documents and other media containing information belonging or relating to the Company or its affiliates. Executive shall promptly disclose in writing to the Company all inventions, discoveries, developments, improvements and innovations (collectively referred to as “Inventions”) that Executive has conceived or made during the Period of Employment; provided, however, that in this context “Inventions” are limited to those which (i) relate in any manner to the existing or contemplated business activities of the Company and its affiliates; (ii) are suggested by or result from Executive’s work at the Company; or (iii) result from the use of the time, materials or facilities of the Company and its affiliates. All Inventions will be the Company’s property rather than Executive’s. Should the Company request it, Executive agrees to sign any document that the Company may reasonably require to establish ownership in any Invention.

4.Cooperation With Regard to Litigation. Executive agrees to cooperate with the Company, during the Period of Employment or at any time thereafter (including following a termination of Executive’s employment for any reason, whether with or without cause, voluntarily or involuntarily, or due to death or disability), by making himself or herself available to testify on behalf of the Company or any subsidiary or affiliate of the Company, in any action, suit, or proceeding, whether civil, criminal, administrative, or investigative, and to assist the Company, or any subsidiary or affiliate of the Company, in any such action, suit, or proceeding, by providing information and meeting and consulting with the Board or its representatives or counsel, or representatives or counsel to the Company, or any subsidiary or affiliate of the Company, as may be reasonably requested and after taking into account Executive’s post-termination responsibilities and obligations. The Company agrees to reimburse Executive, on an after-tax basis, for all reasonable expenses actually incurred in connection with his or her provision of such testimony or assistance as may be requested by the Board or its representatives.

5.Non-Disparagement. Executive shall not, at any time during the Period of Employment or at any time thereafter (including following a termination of Executive’s employment for any reason, whether with or without cause, voluntarily or involuntarily, or due to death or disability) make statements or representations, or otherwise communicate, directly or

3

indirectly, in writing, orally, or otherwise, or take any action which may, directly or indirectly, disparage or be damaging to the Company, its subsidiaries or affiliates or their respective officers, directors, employees, advisors, businesses or reputations. Notwithstanding the foregoing, nothing in this Agreement shall preclude Executive from making truthful statements that are required by applicable law, regulation or legal process.

6.Forfeiture of Outstanding Options and Other Equity Awards. The provisions of Section 7 of the Employment Agreement notwithstanding, if Executive fails to comply with the restrictive covenants under Sections 1, 2 or 3 of this Agreement (the date of such failure, the “Noncompliance Date”), all Covered Equity Awards (as defined below) then held by Executive or a transferee of Executive shall be immediately forfeited and thereupon such Covered Equity Awards shall be cancelled. Notwithstanding the foregoing, Executive shall not forfeit any Covered Equity Award unless and until there shall have been delivered to him or her, within six (6) months after the Board (i) had knowledge of conduct or an event allegedly constituting grounds for such forfeiture and (ii) had reason to believe that such conduct or event could be grounds for such forfeiture, a copy of a resolution duly adopted by a majority affirmative vote of the membership of the Board (excluding Executive) at a meeting of the Board called and held for such purpose (after giving Executive reasonable notice specifying the nature of the grounds for such forfeiture and not less than 30 days to correct the acts or omissions complained of, if correctable, and affording Executive the opportunity, together with his or her counsel, to be heard before the Board) finding that, in the good faith opinion of the Board, Executive has engaged in conduct set forth in this Section 6 which constitutes grounds for forfeiture of Executive’s Covered Equity Awards; provided, however, that if any option is exercised or equity award is settled after delivery of such notice, such option or equity award constitutes a Covered Equity Award, and the Board subsequently makes the determination described in this sentence, Executive shall be required to pay to the Company (or the Operating Partnership, as to any Covered Equity Award granted by the Operating Partnership) an amount equal to the difference between the aggregate value of the shares acquired upon such exercise of the option at the date of the Board determination and the aggregate exercise price paid by Executive and an amount equal to the fair market value of the shares delivered in settlement of the equity award at the date of such determination (net of any cash payment for the shares by Executive). Any such forfeiture shall apply to the Covered Equity Awards notwithstanding any term or provision of any applicable award agreement. In addition, Executive agrees that all compensation paid or payable to Executive shall be subject to (i) the provisions of the Company’s claw-back policy as in effect on the Effective Date, and (ii) any claw-back required by applicable law. For purposes of this Agreement, a “Covered Equity Award” means a stock option, restricted stock, stock unit, performance unit, profit interest, or other equity award that was granted to Executive by the Company or the Operating Partnership after the date that is three years before the Noncompliance Date at issue.

7.Remedies; Waiver of Jury Trial. Executive agrees that any breach of the terms of this Agreement would result in irreparable injury and damage to the Company for which the Company would have no adequate remedy at law. Executive therefore also agrees that in the event of said breach or any threat of breach, and notwithstanding Section13 of the Employment Agreement, the Company shall be entitled to an immediate injunction and restraining order from a court of competent jurisdiction to prevent such breach and/or threatened breach and/or continued breach by Executive and/or any and all persons and/or entities acting for and/or with

4

Executive, without having to prove damages. The availability of injunctive relief shall be in addition to any other remedies to which the Company may be entitled at law or in equity, but remedies other than injunctive relief may only be pursued in an arbitration brought in accordance with Section13 of the Employment Agreement. The terms of this paragraph shall not prevent the Company from pursuing in an arbitration any other available remedies for any breach or threatened breach of this Agreement, including but not limited to the recovery of damages from Executive. Executive, the Operating Partnership, and the Company agree to waive their rights to a jury trial for any claim or cause of action based upon or arising out of this Agreement or any dealings between them relating to the subject matter of this Agreement.

Executive hereby further agrees that, if it is ever determined, in an arbitration brought in accordance with Section13 of the Employment Agreement, that willful actions by Executive have constituted wrongdoing that contributed to any material misstatement or omission from any report or statement filed by the Company with the U.S. Securities and Exchange Commission or material fraud against the Company, then the Company, or its successor, as appropriate, may recover all of any award or payment made to Executive, less the amount of any net tax owed by Executive with respect to such award or payment over the tax benefit to Executive from the repayment or return of the award or payment, pursuant to Section 7 of the Employment Agreement, and Executive agrees to repay and return such awards and amounts to the Company within 30 calendar days of receiving notice from the Company that the Board has made the determination referenced above and accordingly the Company is demanding repayment pursuant to this Section 7. The Company or its successor may, in its sole discretion, affect any such recovery by (i) obtaining repayment directly from Executive; (ii) setting off the amount owed to it against any amount or award that would otherwise be payable by the Company to Executive; or (iii) any combination of (i) and (ii) above.

8.Attorneys’ Fees. If any legal action, arbitration or other proceeding is brought for the enforcement of this Agreement, or because of an alleged dispute, breach or default in connection with any of the provisions of this Agreement, the prevailing party shall be entitled to recover reasonable attorneys’ fees and other costs incurred in that action or proceeding, including any appeal of such action or proceeding, in addition to any other relief to which that party may be entitled.

9.Survival. This Agreement shall survive the termination of Executive’s employment and the assignment of this Agreement by the Operating Partnership or the Company to any successor to their respective business as provided in Section 13.

10.Severability. Any provision of this Agreement which is deemed invalid, illegal or unenforceable in any jurisdiction shall, as to that jurisdiction and subject to this paragraph, be ineffective to the extent of such invalidity, illegality or unenforceability, without affecting in any way the remaining provisions hereof in such jurisdiction or rendering any other provisions of this Agreement invalid, illegal or unenforceable in any other jurisdiction. If any covenant should be deemed invalid, illegal or unenforceable because its scope is considered excessive, such covenant shall be modified so that the scope of the covenant is reduced only to the minimum extent necessary to render the modified covenant valid, legal and enforceable.

5

11.Governing Law and Venue. This Agreement shall be governed, construed, interpreted and enforced in accordance with the laws of the State of California, without regard to the conflict of laws principles thereof. Executive expressly consents to personal jurisdiction and venue in the state and federal courts (a) for the county in which the principal place of the Operating Partnership’s business is located for any lawsuit filed there against Executive by the Operating Partnership arising from or related to this Agreement, or (b) for the county in which the principal place of the Company’s business is located for any lawsuit filed there against Executive by the Company arising from or related to this Agreement.

12.Entire Agreement. This Agreement contains the entire agreement and understanding between the Operating Partnership, the Company and Executive with respect to the subject matter hereof, and supersedes all prior agreements and understandings with respect to the subject matter hereof (including, without limitation, the Prior Employment Agreement), and the parties hereto have made no representations, promises, agreements or understandings, written or oral, relating to the subject matter of this Agreement which are not set forth herein. This Agreement shall not be changed unless in writing and signed by both Executive and an authorized representative of the Operating Partnership and the Company. Notwithstanding anything contained in this Agreement to the contrary, nothing in this Agreement shall be construed as superseding or replacing the terms of the Employment Agreement.

13.Assignment. This Agreement may not be assigned by Executive, but may be assigned by the Operating Partnership and the Company to any successor to their respective business and will inure to the benefit of and be binding upon any such successor.

14.Notice. Whenever under this Agreement it becomes necessary to give notice, such notice shall be in writing, signed by the party or parties giving or making the same, and shall be served on the person or persons for whom it is intended or who should be advised or notified, by Federal Express or other similar overnight service or by certified or registered mail, return receipt requested, postage prepaid and addressed to such party at the address set forth below or at such other address as may be designated by such party by like notice.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Basis of Presentation

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, 2016:

	Number of Buildings	Rentable Square Feet	Number of Tenants	Percentage  Occupied
Stabilized Office Properties	103	13,671,730	523	94.9	%

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. 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.

During the three months ended March 31, 2016, we stabilized two development projects consisting of 455,340rentable square feet and 185,602 rentable square feet in San Francisco, California which were included in our stabilized portfolio as of March 31, 2016. As of March 31, 2016, the following “lease up” properties and development projects under construction were excluded from our stabilized portfolio. We did not have any redevelopment properties at March 31, 2016.

	Number of Properties/Projects	Estimated Rentable Square Feet
Development projects in “lease-up”	2	443,000
Development projects under construction (1)	2	905,000

________________________

(1) Estimated rentable square feet upon completion.

Our stabilized portfolio also excludes our near-term and future development pipeline, which as of March 31, 2016 was comprised oftendevelopment sites, representing approximately 101gross acres of undeveloped land.

As of March 31, 2016, 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 one future development project located in the state of Washington. As of March 31, 2016, we owned 100% of all of our properties and development projects, excluding two recently completed office properties owned by Redwood City Partners, LLC (“Redwood LLC”), a consolidated subsidiary, and one undeveloped land parcel held at a qualified intermediary 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 that been consolidated for financial reporting purposes.

Ownership and 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.

As of March 31, 2016, the Company owned an approximate 97.2% common general partnership interest in the Operating Partnership. The remaining approximate 2.8% common limited partnership interest in the Operating Partnership as of March 31, 2016 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. As of March 31, 2016, the Company owned an approximate 93% equity interest in Redwood LLC. The remaining interest was owned by an unrelated third party. With the exception of the Operating Partnership and Redwood LLC, all of our subsidiaries are wholly owned.

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, 2016. 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, 2015.

Adoption of New Accounting Pronouncements

Variable Interest Entities

Effective January 1, 2016, the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2015-02 (“ASU 2015-02”), which amended certain guidance with respect to the evaluation of Variable Interest Entities (“VIEs”) and when a reporting entity is required to consolidate certain legal entities. Specifically, the amendments: (i) modify the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities, (ii) eliminate the presumption that a general partner should consolidate a limited partnership, (iii) affect the consolidation analysis of reporting entities that are involved with VIEs, and (iv) provide a scope exception for certain entities. 

Under the new guidance, effective January 1, 2016 the Operating Partnership was determined to be a VIE of the Company as the Operating Partnership is a limited partnership in which the common limited partners do not have substantive kick-out rights or participating rights. However, given that the Company was deemed to be the primary beneficiary of the Operating Partnership, the adoption of this new guidance and the conclusion that the Operating Partnership was a VIE did not have any impact on our consolidated financial statements since the conclusion to consolidate the Operating Partnership still applied. The Operating Partnership was the only new VIE identified as part of the adoption of the guidance as of January 1, 2016.

At December 31, 2015 and March 31, 2016, the consolidated financial statements of the Company and the Operating Partnership included two other VIEs in which we were deemed to be the primary beneficiary. One VIE, Redwood LLC, was established in 2013 in connection with an undeveloped land acquisition. The other VIE was established in the fourth quarter of 2015 to facilitate potential future Section 1031 Exchanges to defer taxable gains on dispositions for federal income tax purposes. At March 31, 2016, the impact of consolidating the other VIEs increased the Company’s total assets, liabilities and noncontrolling interests by approximately $208.3 million (of which $187.3 million related to real estate held for investment on our consolidated balance sheet), approximately $26.3 million and approximately $6.7 million, respectively. At December 31, 2015, the impact of consolidating the VIEs increased the Company’s total assets, liabilities and noncontrolling interests by approximately $203.3 million (of which $187.3 million related to real estate held for investment on our consolidated balance sheet), approximately $28.8 million and approximately $6.5 million, respectively.

Effective January 1, 2016, the Company adopted FASB ASU No. 2015-03 and No. 2015-15, which requires that debt issuance costs related to a recognized debt liability be presented on the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. However, for line-of-credit arrangements, entities may defer and present debt issuance costs as an asset and amortize the costs ratably over the term of the line of credit arrangement, regardless of whether there are any outstanding borrowings on the line of credit arrangement. As a result of our adoption of the guidance, $1.1 million of deferred financing costs as of December 31, 2015 were reclassified to reduce secured debt, net and $12.0 million of deferred financing costs as of December 31, 2015 were reclassified to reduce unsecured debt, net in the December 31, 2015 balances on our consolidated balance sheets. In addition, $4.6 million of deferred financing costs relating to our unsecured line of credit as of December 31, 2015 were reclassified to prepaid expenses and other assets, net in the December 31, 2015 balances on our consolidated balance sheets. The guidance did not have a material impact on our consolidated financial statements.

Recently Issued Accounting Pronouncements

On February 25, 2016, the FASB issued ASU No. 2016-02 (“ASU 2016-02”) to amend the accounting guidance for leases. The accounting applied by a lessor is largely unchanged under ASU 2016-02. However, the standard requires lessees to recognize lease assets and lease liabilities for leases classified as operating leases on the balance sheet. Lessees will recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it will recognize lease expense for such leases generally on a straight-line basis over the lease term. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 and early adoption is permitted. The Company is currently assessing the impact of the guidance on our consolidated financial statements and notes to our consolidated financial statements.

On August 12, 2015, the FASB issued ASU No. 2015-14 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, 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 and notes to our consolidated financial statements.

On January 5, 2016, the FASB issued ASU No. 2016-01 to amend the accounting guidance on the classification and measurement of financial instruments. The standard requires that all investments in equity securities, including other ownership interests, are carried at fair value through net income. This requirement does not apply to investments that qualify for equity method accounting or to those that result in consolidation of the investee or for which the entity has elected the predictability exception to fair value measurement. Additionally, the standard requires that the portion of the total fair value change caused by a change in instrument-specific credit risk for financial liabilities for which the fair value option has been elected would be recognized in other comprehensive income. Any accumulated amount remaining in other comprehensive income is reclassified to earnings when the liability is extinguished. The Company does not anticipate the guidance to have a material impact on our consolidated financial statements or notes to our consolidated financial statements.

On March 30, 2016, the FASB issued ASU No. 2016-09 (“ASU 2016-09”) to amend the accounting guidance for share-based payment accounting. The areas for simplification in ASU 2016-09 involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods and early adoption is permitted. The Company is currently assessing the impact of the guidance on our consolidated financial statements and notes to our consolidated financial statements.

Common Units of the Operating Partnership

The Company owned an approximate 97.2%, 98.1% and 98.0% common general partnership interest in the Operating Partnership as of March 31, 2016, December 31, 2015 and March 31, 2015, respectively. The remaining approximate 2.8%, 1.9% and 2.0% common limited partnership interest as of March 31, 2016, December 31, 2015 and March 31, 2015, respectively, was owned by non-affiliated investors and certain of our executive officers and directors in the form of noncontrolling common units. There were 2,631,276, 1,764,775 and 1,793,170common units outstanding held by these investors, executive officers and directors as of March 31, 2016, December 31, 2015 and March 31, 2015, respectively. The increase in the common units from December 31, 2015 to March 31, 2016 was attributable to 867,701 common units issued in connection with an acquisition (see Note 2) partially offset by a unit redemption.

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 $158.8 million and $112.0 million as of March 31, 2016 and December 31, 2015, 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.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Share-Based Compensation

Share-Based Compensation

Stockholder Approved Equity Compensation Plans

As of March 31, 2016, we maintained one share-based incentive compensation plan, the Kilroy Realty 2006 Incentive Award Plan, as amended (the “2006 Plan”). As of March 31, 2016, 1,394,096 shares were available for grant under the 2006 Plan. The calculation of shares available for grant is presented after taking into account a reserve for a sufficient number of shares to cover the vesting and payment of 2006 Plan awards that were outstanding on that date, including performance-based vesting awards at (i) levels actually achieved for the performance conditions (as defined below) and (ii) at target levels for the market conditions (as defined below) applicable to these awards.

2016 Share-Based Compensation Grants

On January 28, 2016, the Executive Compensation Committee of the Company’s Board of Directors awarded 294,821 restricted stock units (“RSUs”) to certain officers of the Company under the 2006 Plan, which included 168,077 RSUs (at the target level of performance), or 57%, that are subject to market and performance-based vesting requirements (the “2016 Performance-Based RSUs”) and 126,744 RSUs, or 43%, that are subject to time-based vesting requirements (the “2016 Time-Based RSUs”).

On January 9, 2016, the Executive Compensation Committee of the Company’s Board of Directors awarded 33,910 RSUs to the Company’s Chief Operating Officer under the 2006 Plan (the “2016 Special RSUs”).

2016 Performance-Based RSU Grant

The 2016 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, 2016 and also based upon the average annual relative total stockholder return ranking for the Company compared to an established comparison group of companies (the “market condition”) for the three-year period ending December 31, 2018. The 2016 Performance-Based RSUs are also subject to a three-year service vesting provision and are scheduled to cliff vest at the end of the three-year period. The number of 2016 Performance-Based RSUs ultimately earned could fluctuate from the target number of 2016 Performance-Based RSUs granted based upon the levels of achievement for both the performance condition and the market condition. The estimate of the number of 2016 Performance-Based RSUs earned are evaluated quarterly during the 2016 performance period based on our estimate as to the 2016 FFO per share performance measured against the applicable goals. As of March 31, 2016, 168,077 2016 Performance-Based RSUs are estimated to be earned based on the Company’s estimate of 2016 FFO per share performance measured against the applicable goals, and the compensation cost recorded to date for this program was based on that estimate. Compensation expense for the 2016 Performance-Based RSU grant will be recorded on a straight-line basis over the three-year period.

Each 2016 Performance-Based RSU represents the right to receive one share of our common stock in the future. The total fair value of the 2016 Performance-Based RSU grant was $9.6 million at January 28, 2016 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 2016 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, 2016, we recorded compensation expense based upon the $57.08 fair value at January 28, 2016. The following table summarizes the assumptions utilized in the Monte Carlo simulation pricing model:

	Fair Value Assumptions
Fair value per share at January 28, 2016	$57.08
Expected share price volatility	26.00%
Risk-free interest rate	1.13%
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 28, 2016. The expected life of the RSUs is equal to the remaining 2.9 year vesting period at January 28, 2016.

2016 Time-Based RSU Grant

The 2016 Time-Based RSUs are scheduled to vest in three equal installments beginning on January 5, 2017 through January 5, 2019. Compensation expense for the 2016 Time-Based RSUs will be recognized on a straight-line basis over the three-year service vesting period. Each 2016 Time-Based RSU represents the right to receive one share of our common stock in the future. The total fair value of the 2016 Time-Based RSU grant was $7.1 million, which was based on the $56.23 closing share price of the Company’s common stock on the NYSE on January 28, 2016.

2016 Special RSU Grant

The 2016 Special RSUs are scheduled to vest in four equal installments beginning on December 31, 2016 through December 31, 2019 based on the achievement of certain metrics. Compensation expense for the 2016 Special RSUs will be recognized on a straight-line basis over the four-year service vesting period. Each 2016 Special RSU represents the right to receive one share of our common stock in the future. The total fair value of the 2016 Special RSU grant was $2.0 million, which was based on the $58.98 closing share price of the Company’s common stock on the NYSE on January 8, 2016 for the time-based portion, and the estimated fair value at date of grant for the performance-based portion.

Share-Based Compensation Cost Recorded During the Period

The total compensation cost for all share-based compensation programs was $5.9 million and $4.3 million for the three months ended March 31, 2016 and 2015, respectively. Of the total share-based compensation costs, $1.2 million and $0.7 million was capitalized as part of real estate assets for the three months ended March 31, 2016 and 2015, respectively. As of March 31, 2016, there was approximately $44.1 million of total unrecognized compensation cost related to nonvested incentive awards granted under share-based compensation arrangements that is expected to be recognized over a weighted-average period of 2.1 years. The remaining compensation cost related to these nonvested incentive awards had been recognized in periods prior to March 31, 2016.

Commitments and Contingencies

General

As of March 31, 2016, we had commitments of approximately $461.1 million, excluding our ground lease commitments, for contracts and executed leases directly related to our operating properties.

Environmental Matters

We follow the policy of monitoring all of our properties, both acquisition and existing stabilized portfolio properties, for the presence of hazardous or toxic substances. 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, 2016, we had accrued environmental remediation liabilities of approximately $26.7 million recorded on our consolidated balance sheets in connection with recent development acquisitions and certain of our development projects. 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 on certain of these projects, potential additional environmental costs are not reasonably estimable at this time.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Consolidation Policy

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.

As of March 31, 2016, the Company owned an approximate 97.2% common general partnership interest in the Operating Partnership. The remaining approximate 2.8% common limited partnership interest in the Operating Partnership as of March 31, 2016 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. As of March 31, 2016, the Company owned an approximate 93% equity interest in Redwood LLC. The remaining interest was owned by an unrelated third party. With the exception of the Operating Partnership and Redwood LLC, all of our subsidiaries are wholly owned.

Basis of Accounting

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, 2016. 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, 2015.

New Accounting Pronouncements

Adoption of New Accounting Pronouncements

Variable Interest Entities

Effective January 1, 2016, the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2015-02 (“ASU 2015-02”), which amended certain guidance with respect to the evaluation of Variable Interest Entities (“VIEs”) and when a reporting entity is required to consolidate certain legal entities. Specifically, the amendments: (i) modify the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities, (ii) eliminate the presumption that a general partner should consolidate a limited partnership, (iii) affect the consolidation analysis of reporting entities that are involved with VIEs, and (iv) provide a scope exception for certain entities. 

Under the new guidance, effective January 1, 2016 the Operating Partnership was determined to be a VIE of the Company as the Operating Partnership is a limited partnership in which the common limited partners do not have substantive kick-out rights or participating rights. However, given that the Company was deemed to be the primary beneficiary of the Operating Partnership, the adoption of this new guidance and the conclusion that the Operating Partnership was a VIE did not have any impact on our consolidated financial statements since the conclusion to consolidate the Operating Partnership still applied. The Operating Partnership was the only new VIE identified as part of the adoption of the guidance as of January 1, 2016.

At December 31, 2015 and March 31, 2016, the consolidated financial statements of the Company and the Operating Partnership included two other VIEs in which we were deemed to be the primary beneficiary. One VIE, Redwood LLC, was established in 2013 in connection with an undeveloped land acquisition. The other VIE was established in the fourth quarter of 2015 to facilitate potential future Section 1031 Exchanges to defer taxable gains on dispositions for federal income tax purposes. At March 31, 2016, the impact of consolidating the other VIEs increased the Company’s total assets, liabilities and noncontrolling interests by approximately $208.3 million (of which $187.3 million related to real estate held for investment on our consolidated balance sheet), approximately $26.3 million and approximately $6.7 million, respectively. At December 31, 2015, the impact of consolidating the VIEs increased the Company’s total assets, liabilities and noncontrolling interests by approximately $203.3 million (of which $187.3 million related to real estate held for investment on our consolidated balance sheet), approximately $28.8 million and approximately $6.5 million, respectively.

Reclassification of Debt Issuance Costs

Effective January 1, 2016, the Company adopted FASB ASU No. 2015-03 and No. 2015-15, which requires that debt issuance costs related to a recognized debt liability be presented on the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. However, for line-of-credit arrangements, entities may defer and present debt issuance costs as an asset and amortize the costs ratably over the term of the line of credit arrangement, regardless of whether there are any outstanding borrowings on the line of credit arrangement. As a result of our adoption of the guidance, $1.1 million of deferred financing costs as of December 31, 2015 were reclassified to reduce secured debt, net and $12.0 million of deferred financing costs as of December 31, 2015 were reclassified to reduce unsecured debt, net in the December 31, 2015 balances on our consolidated balance sheets. In addition, $4.6 million of deferred financing costs relating to our unsecured line of credit as of December 31, 2015 were reclassified to prepaid expenses and other assets, net in the December 31, 2015 balances on our consolidated balance sheets. The guidance did not have a material impact on our consolidated financial statements.

Recently Issued Accounting Pronouncements

On February 25, 2016, the FASB issued ASU No. 2016-02 (“ASU 2016-02”) to amend the accounting guidance for leases. The accounting applied by a lessor is largely unchanged under ASU 2016-02. However, the standard requires lessees to recognize lease assets and lease liabilities for leases classified as operating leases on the balance sheet. Lessees will recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it will recognize lease expense for such leases generally on a straight-line basis over the lease term. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 and early adoption is permitted. The Company is currently assessing the impact of the guidance on our consolidated financial statements and notes to our consolidated financial statements.

On August 12, 2015, the FASB issued ASU No. 2015-14 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, 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 and notes to our consolidated financial statements.

On January 5, 2016, the FASB issued ASU No. 2016-01 to amend the accounting guidance on the classification and measurement of financial instruments. The standard requires that all investments in equity securities, including other ownership interests, are carried at fair value through net income. This requirement does not apply to investments that qualify for equity method accounting or to those that result in consolidation of the investee or for which the entity has elected the predictability exception to fair value measurement. Additionally, the standard requires that the portion of the total fair value change caused by a change in instrument-specific credit risk for financial liabilities for which the fair value option has been elected would be recognized in other comprehensive income. Any accumulated amount remaining in other comprehensive income is reclassified to earnings when the liability is extinguished. The Company does not anticipate the guidance to have a material impact on our consolidated financial statements or notes to our consolidated financial statements.

On March 30, 2016, the FASB issued ASU No. 2016-09 (“ASU 2016-09”) to amend the accounting guidance for share-based payment accounting. The areas for simplification in ASU 2016-09 involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods and early adoption is permitted. The Company is currently assessing the impact of the guidance on our consolidated financial statements and notes to our consolidated financial statements.
