EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended March 31, 2017 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, 2017 , the Company owned an approximate 97.9% common general partnership interest in the Operating Partnership. The remaining approximate 2.1% 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, 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 noncontrolling interests, stockholders’ equity and partners’ capital 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 7, Stockholders’ Equity of the Company;


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


◦	Note 12, Net Income Available to Common Stockholders Per Share of the Company;


◦	Note 13, Net Income Available to Common Unitholders Per Unit of the Operating Partnership;


◦	Note 14, Supplemental Cash Flow Information of the Company; and


◦	Note 15, 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 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, 2017 and 2016

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 and mixed-use 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 properties at March 31, 2017 :



	Number of Buildings	Rentable Square Feet (unaudited)	Number of Tenants	Percentage Occupied (unaudited)		Percentage Leased (unaudited)
Stabilized Office Properties	111	14,394,806	543	94.1	%	95.7	%



	Number of Buildings	Number of Units	Percentage Occupied (unaudited)		Percentage Leased (unaudited)
Stabilized Residential Property	1	200	64.9	%	71.3	%

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 office properties we recently developed or redeveloped that have not yet reached 95% occupancy and are within one year following cessation of major construction activities. There were no operating properties in “lease-up” or held for sale as of March 31, 2017 .

During the three months ended March 31, 2017 , we added one development project to our stabilized office portfolio consisting of 365,359 rentable square feet in Hollywood, California. As of March 31, 2017 , the following properties were excluded from our stabilized portfolio. We did not have any redevelopment properties at March 31, 2017 .



	Number of Properties/Projects	Estimated Rentable Square Feet ⁽¹⁾
Development projects under construction ⁽²⁾	3	1,150,000

________________________


(1)	Estimated rentable square feet upon completion.


(2)	Development projects under construction also include 96,000 square feet of retail space and 237 residential units in addition to the estimated office rentable square feet noted above.

Our stabilized portfolio also excludes our near-term and future development pipeline, which as of March 31, 2017 was comprised of seven development sites, representing approximately 54 gross acres of undeveloped land.

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

As of March 31, 2017 , all of our 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. All of our properties and development projects are 100% owned, excluding four office properties owned by three consolidated property partnerships.

Two of the three property partnerships, 100 First Street Member, LLC (“100 First LLC”) and 303 Second Street Member, LLC (“303 Second LLC”), each owned one office property in San Francisco, California through subsidiary REITs. As of March 31, 2017 , the Company owned a 56% common equity interest in both 100 First LLC and 303 Second LLC. The third property partnership, Redwood City Partners, LLC (“Redwood LLC”) owned two office properties in Redwood City, California. As of March 31, 2017 , the Company owned an approximate 93% common equity interest in Redwood LLC. The remaining interests in all three property partnerships were owned by unrelated third parties.

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, Kilroy Services, LLC (“KSLLC”), 100 First LLC, 303 Second LLC, 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, 100 First LLC, 303 Second LLC, 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, 2017 , the Company owned an approximate 97.9% common general partnership interest in the Operating Partnership. The remaining approximate 2.1% common limited partnership interest in the Operating Partnership as of March 31, 2017 , was owned by non-affiliated investors and certain of our executive officers and directors (see Note 6). 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”.

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. We conduct substantially all of our development activities through KSLLC, which is a wholly owned subsidiary of the Operating Partnership. With the exception of the Operating Partnership and our consolidated property partnerships, 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, 2017 . 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, 2016 .

Variable Interest Entities

The Operating Partnership is a variable interest entity (“VIE”) of the Company as the Operating Partnership is a limited partnership in which the common limited partners do not have substantive kick-out or participating rights. At March 31, 2017 , the consolidated financial statements of the Company included two VIEs in addition to the Operating Partnership: 100 First LLC and 303 Second LLC. At March 31, 2017 , the Company and the Operating Partnership were determined to be the primary beneficiary of these two VIEs since we had the ability to control the activities that most significantly impact each of the VIE’s economic performance. As of March 31, 2017 , the VIEs’ total assets, liabilities and noncontrolling interests included on our consolidated balance sheet were approximately $438.5 million (of which $389.4 million related to real estate held for investment), approximately $156.6 million and approximately $125.7 million , respectively. Revenues, income and net assets generated by 100 First LLC and

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

303 Second LLC may only be used to settle its contractual obligations, which primarily consist of operating expenses, capital expenditures and required distributions.

At December 31, 2016 , the consolidated financial statements of the Company and the Operating Partnership included three VIEs in which we were deemed to be the primary beneficiary: 100 First LLC, 303 Second LLC and an entity established during the fourth quarter of 2016 to facilitate a transaction intended to qualify as a like-kind exchange pursuant to Section 1031 of the Code (“Section 1031 Exchange”). In January 2017, the Section 1031 Exchange was successfully completed and the entity established for the 1031 Exchange was no longer a VIE. At December 31, 2016 , the impact of consolidating the VIEs increased the Company’s total assets, liabilities and noncontrolling interests by approximately $654.3 million (of which $588.6 million related to real estate held for investment on our consolidated balance sheet), approximately $166.1 million and approximately $124.3 million , respectively.

Adoption of New Accounting Pronouncements

Effective January 1, 2017, the Company adopted FASB ASU No. 2017-01 (“ASU 2017-01”) which clarifies the framework for determining whether an integrated set of assets and activities meets the definition of a business. The revised framework provides a screen for determining whether an integrated set of assets is a business combination or an asset acquisition and clarifies that when substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar assets, the set of assets and activities is deemed not to meet the definition of a business. As a result of our adoption of the guidance, which we adopted on a prospective basis, the Company expects that most of our future acquisitions of operating properties and development properties that were previously accounted for as business combinations will instead be accounted for as asset acquisitions under the new guidance. In addition, we expect that most of the transaction costs associated with these future acquisitions will be capitalized as part of the purchase price of the acquisition instead of being expensed as incurred to acquisition-related expenses. The Company did not have any acquisitions during the three months ended March 31, 2017 .

Also effective January 1, 2017, the Company adopted ASU No. 2016-18 (“ASU 2016-18”) which requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The Company adopted ASU 2016-18 on a retrospective basis. Therefore, amounts generally described as restricted cash and restricted cash equivalents are included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the Company’s consolidated statements of cash flows for the three months ended March 31, 2017 and 2016 . As a result of the adoption of ASU 2016-18, the change in restricted cash is no longer presented as a separate line item within cash flows from investing activities on the Company’s consolidated statements of cash flows since such balances are now included in total cash at both the beginning and end of the reporting period. As a result, for the three months ended March 31, 2016 , the Company had net cash provided by investing activities of $134.2 million instead of net cash used in investing activities of $126.7 million as previously reported since the Company had $258.1 million of restricted cash at March 31, 2016 that was held at qualified intermediaries to facilitate potential future Section1031 Exchanges.

In addition, effective January 1, 2017, the Company adopted ASU No. 2016-09 (“ASU 2016-09”) which simplified 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. The adoption of this guidance did not have an impact on our consolidated financial statements or notes to our consolidated financial statements.

Recently Issued Accounting Pronouncements

ASU No. 2016-02 “Leases (Topic 842)”

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.

We are currently conducting our evaluation of the impact of the guidance on our consolidated financial statements and have an active project team working on the evaluation and implementation of the guidance as well as commencing the process of compiling an inventory of our lessor portfolio. We currently believe that the adoption of the standard will not significantly change the accounting for operating leases on our consolidated balance sheets where we are the lessor, and that such leases will be accounted

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

for in a similar method to existing standards with the underlying leased asset being reported and recognized as a real estate asset. We currently expect that certain non-lease components will need to be accounted for separately from the lease components, with the lease components (including property taxes and insurance costs) continuing to be recognized on a straight-line basis over the term of the lease and certain non-lease components (such as common area maintenance and provision of utilities) being accounted for under the new revenue recognition guidance in ASU 2014-09 discussed below, even when revenue for such non-lease components is not separately stipulated in the lease. In addition, under ASU 2016-02, lessors will only be permitted to capitalize and amortize incremental direct leasing costs. As a result, we expect that upon the adoption of the standard, we will no longer be able to capitalize and amortize certain leasing related costs and instead will expense these costs as incurred. We currently expect this could have a material impact to the Company’s results of operations upon adoption of the standard.

For leases where we are the lessee, specifically for our ground leases, we currently believe that the adoption of the standard will significantly change the accounting on our consolidated balance sheets since both existing ground leases and any future ground leases will be required to be recorded on the Company’s consolidated balance sheets as an obligation of the Company. While we are still evaluating the guidance, we currently believe that existing ground leases executed before the January 1, 2019 adoption date will continue to be accounted for as operating leases and will not have a material impact on our recognition of ground lease expense or our results of operations. However, we believe that we will be required to recognize a right of use asset and a lease liability on our consolidated balance sheets equal to the present value of the minimum lease payments required in accordance with each ground lease. As of March 31, 2017, our future undiscounted minimum rental payments under these leases totaled $255.1 million , with several of the leases containing provisions for rental payments to fluctuate based on fair market value and income measurements with expirations through 2093. In addition, we currently believe that for new ground leases entered into after the adoption date of the new standard, such leases could be required to be accounted for as a financing type lease, resulting in ground lease expense recorded using the effective interest method instead of on a straight-line basis over the term of the lease. This could have a significant impact on our results of operations if we enter into material new ground leases after the date of adoption since ground lease expense calculated using the effective interest method results in an increased amount of ground lease expense in the earlier years of a ground lease as compared to the current straight-line method.

We will adopt the guidance on a modified retrospective basis as required by ASU 2016-02. We are in the process of evaluating whether we will elect to apply the practical expedients identified in the standard but currently believe that we may do so.

ASU No. 2014-9 “ Revenue From Contracts with Customers (Topic 606)”

In May 2014, the FASB issued ASU 2014-09 “Revenue From Contracts with Customers (Topic 606)” (“ASU 2014-09”). The objective of ASU 2014-09 is to establish a single comprehensive model for entities to use in accounting for revenue from contracts with customers and will supersede most of the existing revenue recognition guidance. On May 9, 2016 and December 21, 2016, the FASB issued ASU No. 2016-12 and ASU No. 2016-20, which provides practical expedients, technical corrections, and improvements for certain aspects of ASU No. 2014-09. 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.

We are currently conducting our evaluation of the impact of the guidance on our consolidated financial statements and we have an active project team working on evaluation and implementation of the guidance. We have been compiling an inventory of the sources of revenue that the Company expects will be impacted by ASU 2014-09. Specifically, we have evaluated the impact on the timing of gain recognition for dispositions but currently do not believe there will be a material impact to our consolidated financial statements for dispositions given the simplicity of the Company’s historical disposition transactions. In addition, we currently believe that certain non-lease components of revenue from leases (upon the adoption of ASU 2016-02 on January 1, 2019) and parking revenue may be impacted by the adoption of ASU 2014-09. We are in the process of evaluating the impact of the standard but currently believe the impact would be limited to the timing and income statement presentation of revenue and not the total amount of revenue recognized over time.

Other Recently Issued Pronouncements

On February 22, 2017, the FASB issued ASU No. 2017-05 “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20)” (“ASU 2017-05”) to provide guidance and clarify the scope of the original guidance within Subtopic 610-20 “Gains and Losses from the Derecognition of Nonfinancial Assets” that was issued in connection with ASU 2014-09, which provided guidance for recognizing gains and losses from the transfer of non financial assets in transactions with noncustomers. ASU 2017-05 additionally adds guidance pertaining to the partial sales of real estate and clarifies that nonfinancial assets within the scope of Accounting Standards Codification Subtopic 610-20 may include nonfinancial assets transferred within a legal entity to a counterparty. For example, a parent may transfer control of nonfinancial assets by transferring ownership interests in a consolidated subsidiary. ASU 2017-05 is effective for fiscal years beginning after December 15, 2017, with early application permitted for fiscal years beginning after December 15, 2016. We are currently evaluating the impact of ASU 2017-05 on our

consolidated financial statements and currently do not anticipate that the guidance will have a material impact on our consolidated financial statements or notes to our consolidated financial statements.

On August 26, 2016, the FASB issued ASU No. 2016-15 (“ASU 2016-15”) to provide guidance for areas where there is diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company does not currently anticipate that the guidance will have a material impact on our consolidated financial statements or notes to our consolidated financial statements.

On June 16, 2016, the FASB issued ASU No. 2016-13 (“ASU 2016-13”) to amend the accounting for credit losses for certain financial instruments. Under the new guidance, an entity recognizes its estimate of expected credit losses as an allowance, which the FASB believes will result in more timely recognition of such losses. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company does not currently anticipate that the guidance will have a material impact on our consolidated financial statements or notes to our consolidated financial statements.

On January 5, 2016, the FASB issued ASU No. 2016-01 (“ASU 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. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017. The Company does not currently anticipate that the guidance will have a material impact on our consolidated financial statements or notes to our consolidated financial statements.

Debt Covenants and Restrictions

The unsecured revolving credit facility, the unsecured term loan facility, the unsecured term loan, the unsecured senior notes, the Series A and B 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, 2017 .

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

Common Units of the Operating Partnership

The Company owned an approximate 97.9% , 97.5% and 97.2% common general partnership interest in the Operating Partnership as of March 31, 2017 , December 31, 2016 and March 31, 2016 , respectively. The remaining approximate 2.1% , 2.5% and 2.8% common limited partnership interest as of March 31, 2017 , December 31, 2016 and March 31, 2016 , respectively, was owned by non-affiliated investors and certain of our executive officers and directors in the form of noncontrolling common units. There were 2,077,193 , 2,381,543 and 2,631,276 common units outstanding held by these investors, executive officers and directors as of March 31, 2017 , December 31, 2016 and March 31, 2016 , respectively.

The noncontrolling common units may be redeemed by unitholders for cash. Except under certain circumstances, we, at our option, may satisfy the cash redemption obligation with shares of the Company’s common stock on a one-for-one basis. If satisfied in cash, the value for each noncontrolling common unit upon redemption is the amount equal to the average of the closing quoted price per share of the Company’s common stock, par value $.01 per share, as reported on the NYSE for the ten trading days immediately preceding the applicable redemption date. The aggregate value upon redemption of the then-outstanding noncontrolling common units was $150.2 million and $174.9 million as of March 31, 2017 and December 31, 2016 , 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.

7. Stockholders’ Equity of the Company

Preferred Stock Redemption

On March 30, 2017 (the “Redemption Date”), the Company redeemed all 4,000,000 shares of its 6.875% Series G Cumulative Redeemable Preferred Stock (“Series G Preferred Stock”). The shares of Series G Preferred Stock were redeemed at a redemption price equal to their stated liquidation preference of $25.00 per share, representing $100.0 million in aggregate, plus all accrued and unpaid dividends to the Redemption Date.

During the three months ended March 31, 2017 , we recognized a non-recurring non-cash charge of $3.8 million as a reduction to net income available to common stockholders for the original issuance costs related to the Series G Preferred Stock.

Common Stock Issuance

In January 2017, the Company completed an underwritten public offering of 4,427,500 shares of its common stock. The net offering proceeds, after deducting underwriting discounts and offering expenses, were approximately $308.8 million . We used a portion of the proceeds to partially fund our 2016 special dividend and will use the remaining proceeds for general corporate uses, to fund development expenditures, for potential future acquisitions and to repay outstanding indebtedness.

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, 2017 . Since commencement of the program through March 31, 2017 , we have sold 2,459,165 shares of common stock having an aggregate gross sales price of $182.4 million . As of March 31, 2017 , shares of common stock having an aggregate gross sales price of up to $117.6 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.

Payment of 2016 Special Cash Dividend

On January 13, 2017 , the Company paid $184.3 million of special cash dividends, which was the equivalent of $1.90 of special cash dividend per share of common stock to stockholders of record on December 30, 2016 . This special dividend payment was in addition to the $36.4 million of regular dividends we also paid on January 13, 2017 to common stockholders, unitholders and RSU holders of record on December 30, 2016 .

8. Partners’ Capital of the Operating Partnership

Preferred Stock Redemption

On March 30, 2017 , the Company redeemed all 4,000,000 units of its 6.875% Series G Cumulative Redeemable Preferred Stock. For each share of Series G Preferred Stock that was outstanding, the Company had an equivalent number of 6.875% Series G Preferred Units (“Series G Preferred Units”) outstanding with substantially similar terms as the Series G Preferred Stock. In connection with the redemption of the Series G Preferred Stock, the Series G Preferred Units held by the Company were redeemed by the Operating Partnership.

Issuance of Common Units

In January 2017, the Company completed an underwritten public offering of 4,427,500 shares of its common stock as discussed in Note 7. The net offering proceeds of approximately $308.8 million were contributed by the Company to the Operating Partnership in exchange for 4,427,500 common units.

9. Share-Based Compensation

Stockholder Approved Equity Compensation Plans

As of March 31, 2017 , we maintained one share-based incentive compensation plan, the Kilroy Realty 2006 Incentive Award Plan, as amended (the “2006 Plan”). As of March 31, 2017 , 1,143,265 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) for which the performance period has been completed and (ii) at target levels for the performance or market conditions (as defined below) for awards still in a performance period.

2017 Share-Based Compensation Grants

In February 2017 , the Executive Compensation Committee of the Company’s Board of Directors awarded 229,976 restricted stock units (“RSUs”) to certain officers of the Company under the 2006 Plan, which included 130,956 RSUs (at the target level of performance), or 57% , that are subject to market and/or performance-based vesting requirements (the “2017 Performance-Based RSUs”) and 99,020 RSUs, or 43% , that are subject to time-based vesting requirements (the “2017 Time-Based RSUs”).

2017 Performance-Based RSU Grant

The 2017 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 for the year ending December 31, 2017 (the “FFO performance condition”) and also based upon either the average FAD per share growth or the Company’s average debt to EBITDA ratio (the “other performance conditions”) or 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, 2019. The 2017 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 2017 Performance-Based RSUs ultimately earned could fluctuate from the target number of 2017 Performance-Based RSUs granted based upon the levels of achievement for the FFO performance condition, the other performance conditions and the market condition. The estimate of the number of 2017 Performance-Based RSUs earned is evaluated quarterly during the performance period based on our estimate for each of the performance conditions measured against the applicable goals. As of March 31, 2017 , the number of 2017 Performance-Based RSUs estimated to be earned based on the Company’s estimate of the performance conditions measured against the applicable goals was 130,956 , and the compensation cost recorded to date for this program was based on that estimate. Compensation expense for the 2017 Performance-Based RSU grant will be recorded on a straight-line basis over the three -year period.

Each 2017 Performance-Based RSU represents the right, subject to the applicable vesting conditions, to receive one share of our common stock in the future. The total fair value of the 2017 Performance-Based RSU grant was $10.3 million at February 24, 2017 . The determination of the fair value of the 2017 Performance-Based RSU grant with other performance conditions takes into consideration the likelihood of achievement of the FFO performance condition and the other performance conditions. The grant date fair value for the performance awards with a market condition was calculated using a Monte Carlo simulation pricing model based on the assumptions in the table below. For the portion of the 2017 Performance-Based RSUs subject to the market

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

condition, for the three months ended March 31, 2017 , we recorded compensation expense based upon the $80.89 fair value at February 24, 2017 . The following table summarizes the assumptions utilized in the Monte Carlo simulation pricing model:



	Fair Value Assumptions
Fair value per share at February 24, 2017	$80.89
Expected share price volatility	21.00%
Risk-free interest rate	1.39%
Remaining expected life	2.8 years

The computation of expected volatility is based on a blend of the historical volatility of our shares of common stock over approximately 5.6 years, as that is expected to be most consistent with future volatility and equates to a time period twice as long as the approximate 2.8 -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 February 24, 2017 . The expected life of the RSUs is equal to the remaining 2.8 year vesting period at February 24, 2017 .

2017 Time-Based RSU Grant

The 2017 Time-Based RSUs are scheduled to vest in three equal installments beginning on January 5, 2018 through January 5, 2020. Compensation expense for the 2017 Time-Based RSUs will be recognized on a straight-line basis over the three -year service vesting period. Each 2017 Time-Based RSU represents the right to receive one share of our common stock in the future. The total fair value of the 2017 Time-Based RSU grant was $7.5 million , which was based on the $73.30 and $77.16 closing share prices of the Company’s common stock on the NYSE on the February 3, 2017 and February 24, 2017 grant dates, respectively.

Share-Based Award Activity

During the three months ended March 31, 2017 , 200,000 non-qualified stock options were exercised and issued at an exercise price per share equal to $42.61 . As of March 31, 2017 , there were 111,500 stock options outstanding.

Share-Based Compensation Cost Recorded During the Period

The total compensation cost for all share-based compensation programs was $6.2 million and $5.9 million for the three months ended March 31, 2017 and 2016 , respectively. Of the total share-based compensation costs, $2.0 million and $1.2 million was capitalized as part of real estate assets and deferred leasing costs for the three months ended March 31, 2017 and 2016 , respectively. As of March 31, 2017 , there was approximately $41.1 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, 2017 .

10. Commitments and Contingencies

General

As of March 31, 2017 , we had commitments of approximately $560.5 million , excluding our ground lease commitments, for contracts and executed leases directly related to our operating properties and development projects.

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.

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

As of March 31, 2017 , we had accrued environmental remediation liabilities of approximately $23.9 million recorded on our consolidated balance sheets in connection with certain development projects and recent development acquisitions. It is possible that we could incur additional environmental remediation costs in connection with these recent development acquisitions. However, given we are in the early stages of development on certain of these projects, potential additional environmental costs are not reasonably estimable at this time.

11. Fair Value Measurements and Disclosures

Assets and Liabilities Reported at Fair Value

The only assets we record at fair value on our consolidated financial statements are the marketable securities related to our Deferred Compensation Plan. The following table sets forth the fair value of our marketable securities as of March 31, 2017 and December 31, 2016 :



	Fair Value (Level 1) ⁽¹⁾
	March 31, 2017		December 31, 2016

Marketable securities ⁽²⁾	$	15,163	$	14,773

________________________


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


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

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

The following table sets forth the net gain on marketable securities recorded during the three months ended March 31, 2017 and 2016 :

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 our plans, objectives, capital resources, portfolio performance, results of operations, projected future occupancy and rental rates, lease expirations, debt maturities, potential investments, strategies such as capital recycling, development and redevelopment activity, projected construction costs, projected construction commencement and completion dates, projected square footage of office space that could be constructed on undeveloped land that we own, projected rentable square footage of or number of units in properties under construction or in the development pipeline, anticipated proceeds from capital recycling activity or other dispositions and anticipated dates of those activities or dispositions, projected increases in the value of properties, dispositions, future executive incentive compensation, pending, potential or proposed acquisitions, plans to grow our Net Operating Income and FFO, anticipated market conditions and demographics and other forward-looking financial data, as well as the discussion in “—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,” “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 the forward-looking statements, including, among others: global market and general economic conditions and their effect on our liquidity and financial conditions and those of our tenants; adverse economic or real estate conditions generally, and specifically, in the States of California and Washington; risks associated with our investment in real estate assets, which are illiquid and with trends in the real estate industry; defaults on or non-renewal of leases by tenants; any significant downturn in tenants' businesses; our ability to release property at or above current market rates; costs to comply with government regulations, including environmental remediations; the availability of cash for distribution and debt service and exposure to risk of default under debt obligations; increases in interest rates and our ability to manage interest rate exposure; the availability of financing on attractive terms or at all, which may adversely impact our future interest expense and our ability to pursue development, redevelopment and acquisition opportunities and refinance existing debt; a decline in real estate asset valuations, which may limit our ability to dispose of assets at attractive prices or obtain or maintain debt financing, and which may result in write offs or impairment charges; significant competition, which may decrease the occupancy and rental rates of properties; potential losses that may not be covered by insurance; the ability to successfully complete acquisitions and dispositions on announced terms; the ability to successfully operate acquired, developed and redeveloped properties; the ability to successfully complete development and redevelopment projects on schedule and within budgeted amounts; delays or refusals in obtaining all necessary zoning, land use and other required entitlements, governmental permits and authorizations for our development and redevelopment properties; increases in anticipated capital expenditures, tenant improvement and/or leasing costs; defaults on leases for land on which some of our properties are located; adverse changes to, or implementations of, applicable laws, regulations or legislation; risks associated with joint venture investments, including our lack of sole decision-making authority, our reliance on co-venturers' financial condition and disputes between us and our co-venturers; environmental uncertainties and risks related to natural disasters; and our ability to maintain our status as a REIT. The factors included in this report are not exhaustive and additional factors could adversely affect our business and financial performance. For a discussion of additional factors that could materially adversely affect the Company's and the Operating Partnership's business and financial performance, see the discussion below as well as “Item 1A. Risk Factors” and in our “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, 2016 and their respective other filings with the SEC. All forward-looking statements are based on currently available information 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.

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Overview and Background

We are a self-administered REIT active in premier office and mixed-use 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 97.9% , 97.5% and 97.2% general partnership interest in the Operating Partnership as of March 31, 2017 , December 31, 2016 and March 31, 2016 , respectively. All of our properties are held in fee except for the thirteen 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, stabilization of recently completed development projects, and, 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.

Stabilized Development Projects

During the three months ended March 31, 2017 , we added the following project to our stabilized portfolio since the project had reached one year from building shell substantial completion:


•	Columbia Square Phase 2 - Office, 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 365,359 rentable square feet with a total estimated investment of approximately $230 million . As of March 31, 2017 , the project was 86% leased and 75% occupied.

Projects Under Construction

As of March 31, 2017 , we had three projects in our in-process development pipeline that were under construction.

•

The Exchange on 16th, Mission Bay, San Francisco, California, which we acquired in May 2014 and commenced construction on in June 2015. This project is currently anticipated to encompass approximately 750,000 gross rentable square feet of office and life science space in four buildings at a total estimated investment of $560.0 million . Construction is currently in progress and the building and core shell are currently estimated to be completed in the first half of 2018.

•

100 Hooper, San Francisco, California, which we acquired in July 2015 and commenced construction on in November 2016. This project is fully entitled for approximately 314,000 square feet of office and approximately 86,000 square feet of PDR space configured in two, four-story buildings. The total estimated cost for this project is approximately $270.0 million . Construction is currently in process and the core and shell of the project is currently expected to be completed in the first half of 2018. The office portion of the project is 100% pre-leased to Adobe Systems Inc. In connection with 100 Hooper, the Company also intends to develop an adjacent 50,000 square foot PDR space located at 150 Hooper with a total estimated investment of approximately $22.0 million.


•	One Paseo - Phase I (Retail and Residential), San Diego, California, which we acquired in November 2007 and commenced construction on in December 2016. Phase I of this mixed-use project includes site work and related infrastructure for the entire project, as well as 237 residential units and approximately 96,000 square feet of retail space. The total estimated

investment for this project is approximately $225.0 million . Construction is currently in process and is currently expected to be completed in phases beginning in the second quarter of 2018.

Near-Term and Future Development Pipeline

As of March 31, 2017 , our near-term development pipeline included three additional undeveloped land holdings located in various submarkets in San Diego County, Greater Seattle and Los Angeles with an aggregate cost basis of approximately $290.1 million at which we believe we could develop approximately 1.9 million rentable square feet at a total estimated investment of over $1.2 billion, depending on successfully obtaining entitlements and market conditions.

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 ($ in millions)		Total Costs as of 3/31/2017 ⁽³⁾ ($ in millions)

333 Dexter ⁽⁴⁾	South Lake Union	2017	700,000	$	385	$	75.5
Academy Project	Hollywood	2017	545,000	390		77.3

Total Near-Term Development Pipeline			1,885,000	$	1,215	$	290.1

________________________


(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.


(3)	Represents cash paid and costs incurred as of March 31, 2017 .


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

As of March 31, 2017 , 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 $306.3 million , at which we believe we could develop more than 2.5 million developable square feet, depending on successfully obtaining entitlements and market conditions.

Fluctuations in our development activities could cause fluctuations in the average development asset balances qualifying for interest and other carry cost and internal cost capitalization in future periods. During the three months ended March 31, 2017 and 2016 , we capitalized interest on in-process development projects and development pipeline projects with an average aggregate cost basis of approximately $1.0 billion and $1.3 billion, respectively, as it was determined these projects qualified for interest and other carry cost capitalization under GAAP. For the three months ended March 31, 2017 and 2016 , we capitalized $10.2 million and $14.3 million , respectively, of interest to our qualifying development projects. For the three months ended March 31, 2017 and 2016 , we capitalized $5.7 million and $4.6 million , respectively, of internal costs to our qualifying development projects.

Acquisitions . 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, life sciences, 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 or the formation of strategic ventures with the intent of recycling the proceeds generated 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 and other tax deferred transaction structures, 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, 2017 , we completed the sale of one operating property to an unaffiliated third party for gross proceeds of $12.1 million .

Incentive Compensation . Our Executive Compensation Committee determines compensation, including cash bonuses and equity incentives, for our executive officers. For 2017, 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 and/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, liquidity measures, 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, 2017 , there was approximately $41.1 million of total unrecognized compensation cost related to outstanding nonvested shares of restricted common stock and RSUs issued under share-based compensation arrangements. Those costs are expected to be recognized over a weighted-average period of 2.1 years. The $41.1 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.

Information on Leases Commenced and Executed

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, 2017 .

(1)	Includes 100% of consolidated property partnerships.


(2)	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.


(3)	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.


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


(5)	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.


(6)	Excludes commenced and executed leases of approximately 44,661 and 30,854 square feet, respectively, for the three months ended March 31, 2017 , 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.


(7)	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.


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


(9)	For the three months ended March 31, 2017 , 16 leases totaling 236,716 rentable square feet were signed but not commenced as of March 31, 2017 .

As of March 31, 2017 , we believe that the weighted average cash rental rates for our total stabilized portfolio are approximately 16% below the current average market rental rates, which includes a projection that the weighted average cash rental rates for our

San Diego stabilized portfolio are approximately 8% above current market rental rates. 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.

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

Scheduled Lease Expirations . The following table sets forth certain information regarding our lease expirations for our stabilized portfolio for the remainder of 2017 and the next five years.

________________________


(1)	For leases that have been renewed early with existing tenants, the expiration date and annualized base rent information presented takes into consideration the renewed lease terms. Excludes leases not commenced as of March 31, 2017 , space leased under month-to-month leases, storage leases, vacant space and future lease renewal options not executed as of March 31, 2017 .

(2)

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

In addition to the 0.9 million rentable square feet, or 5.9% , of currently available space in our stabilized portfolio, leases representing approximately 5.7% and 9.3% of the occupied square footage of our stabilized portfolio are scheduled to expire during 2017 and 2018 , respectively. The leases scheduled to expire during the remainder of 2017 and in 2018 represent approximately 2.0 million rentable square feet or 14.5% of our total annualized base rental revenue. 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.

For the 757,355 rentable square feet or 5.3% of our total annualized base rental revenue scheduled to expire during the remainder of 2017 , we believe that the weighted average cash rental rates in the aggregate are approximately 15% below the current average market rental rates. For the approximately 1.2 million rentable square feet or 9.2% of our total annualized base rental revenue scheduled to expire in 2018 we believe that the weighted average cash rental rates in the aggregate, are approximately at current average market rental rates. Of the 1.2 million rentable square feet scheduled to expire in 2018, 324,677 rentable square feet or 2.9% of our total annualized base rental revenue is located in San Francisco submarkets and we currently believe these expiring leases are approximately 30% below market, and 455,677 rentable square feet or 3.7% of our total annualized base rental revenue is located in San Diego submarkets and we currently believe these expiring leases are approximately 30% above market.

Stabilized Portfolio Information

As of March 31, 2017 , our stabilized portfolio was comprised of 111 office properties encompassing an aggregate of approximately 14.4 million rentable square feet and 200 residential units. 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 office properties we recently developed or redeveloped that have not yet reached 95% occupancy and are within one year following cessation of major construction activities. We did not have any lease up, redevelopment or held for sale properties at March 31, 2017 .

As of March 31, 2017 , the following properties were excluded from our stabilized portfolio:

Development projects under construction ⁽²⁾	3	1,150,000

________________________


(1)	Estimated rentable square feet upon completion.


(2)	Development projects under construction also include 96,000 square feet of retail space and 237 residential units in addition to the estimated office rentable square feet noted above.

Our stabilized portfolio also excludes our near-term and future development pipeline, which as of March 31, 2017 was comprised of seven potential development sites, representing approximately 54 gross acres of undeveloped land on which we believe we have the potential to develop over 4.8 million square feet of office space, depending upon economic conditions.

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 consolidated operating revenues (rental income, tenant reimbursements and other property income) less consolidated 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 because we believe it helps both investors and management to understand the core operations of our properties excluding corporate and financing-related costs and non-cash 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 from operations or net income. 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 from operations or net income.

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


•	Same Store Properties – includes the consolidated 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, 2016 and still owned and included in the stabilized portfolio as of March 31, 2017 ;


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


◦	One office development project that was added to the stabilized portfolio in the first quarter of 2017;


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


◦	Our residential project that was completed in June 2016; and


◦	One office development project that was added to the stabilized portfolio in the fourth quarter of 2016;


•	Acquisition Properties – includes the results, from the dates of acquisition through the periods presented, for the four office and three retail buildings we acquired in three transactions during 2016; and


•	Dispositions and Other – includes the results of the one property disposed of during the first quarter of 2017, the six properties disposed of in 2016 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 office portfolio as of March 31, 2017 :

Net Operating Income increased $19.5 million , or 18.2% , for the three months ended March 31, 2017 as compared to the three months ended March 31, 2016 driven by the following activity:


•	An increase in Net Operating Income of $2.9 million attributable to the Same Store Properties primarily resulting from:


•	An increase in rental income of $1.5 million primarily due to:


◦	$3.7 million increase from new leases and renewals at higher rates across all regions; partially offset by


◦	$2.2 million decrease due to lease expirations and early terminations in the San Francisco Bay area;


•	An increase in tenant reimbursements of $3.9 million primarily due to the following:


◦	$1.6 million increase primarily due to lower reimbursable supplemental taxes in 2016 as a result of a change in estimate at one property;


◦	$1.3 million increase due to higher reimbursable expenses and increased occupancy at various properties across multiple regions;


◦	$1.0 million increase due to lower abated tenant reimbursements and leases with higher expenses than their 2016 base years;


•	An increase in other property income of $2.8 million primarily due to early termination fees in the San Francisco Bay area;

General and Administrative Expenses

General and administrative expenses increased by approximately $1.5 million , or 11.1% , for the three months ended March 31, 2017 compared to the three months ended March 31, 2016 primarily due to an increase in compensation related expenses primarily related to growth of the Company.

Depreciation and Amortization

Depreciation and amortization increased by approximately $10.5 million , or 20.8% , for the three months ended March 31, 2017 compared to the three months ended March 31, 2016 primarily due to the following:

Interest expense	$	17,352		$	11,829		$	5,523	46.7	%

Gross interest expense, before the effect of capitalized interest and deferred financing costs, increased $1.3 million , or 5.1% , for the three months ended March 31, 2017 compared to the three months ended March 31, 2016 primarily due to an increase in the average outstanding debt balance for the three months ended March 31, 2017 . Capitalized interest and deferred financing costs decreased $4.2 million or 29.2% for the three months ended March 31, 2017 compared to the three months ended March 31, 2016 primarily due to a decrease in the average development asset balances qualifying for interest capitalization during the three months ended March 31, 2017 .

Net income attributable to noncontrolling interests in consolidated property partnerships

Net income attributable to noncontrolling interests in consolidated property partnerships increased $2.9 million for the three months ended March 31, 2017 compared to the three months ended March 31, 2016 . The amount reported for the three months ended March 31, 2017 is comprised of the noncontrolling interest’s share of net income for 100 First Street Member, LLC (“100 First LLC”) and 303 Second Street Member (“303 Second LLC”) which closed on August 30, 2016 and November 30, 2016, respectively, in addition to the noncontrolling interest’s share of net income for Redwood City Partners, LLC (“Redwood LLC”). The amount reported for the three months ended March 31, 2016 is comprised of the noncontrolling interest’s share of net income for Redwood City Partners, LLC (“Redwood LLC”).

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 and funds from its capital recycling program, including strategic ventures, 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, 2017 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 gains) 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. As the Company intends to maintain distributions at a level sufficient to meet the REIT distribution requirements and minimize its obligation to pay income and excise taxes, it will continue to evaluate whether the current levels of distribution are sufficient to do so for 2017. In addition, in the event 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 future property dispositions, the Company may elect to distribute a special dividend to its common stockholders and common unitholders in order to 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 28, 2017 , the Board of Directors declared a regular quarterly cash dividend of $0.375 per share of common stock payable on April 12, 2017 to stockholders of record on March 31, 2017 and caused a $0.375 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 12, 2017 were $37.6 million .

On February 28, 2017 , the Board of Directors declared a dividend of $0.39844 per share on the Series H Preferred Stock for the period commencing on and including February 15, 2017 and ending on and including May 14, 2017. The dividend will be payable on May 15, 2017 to Series H Preferred stockholders of record on April 30, 2017 . As April 30, 2017 falls on a Sunday, the effective record date for the dividend will be Friday, April 28, 2017. The quarterly dividends payable on May 15, 2017 to Series H Preferred stockholders is expected to total $1.6 million . In connection with the redemption of the Company’s 6.875% Series G Cumulative Redeemable Preferred Stock (“Series G Preferred Stock”) on March 30, 2017, accumulated and unpaid dividends of $0.21 per share were paid to the Series G Preferred stockholders. The total dividends paid upon redemption were $0.8 million.

Debt Covenants

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

Capitalization

As of March 31, 2017 , our total debt as a percentage of total market capitalization was 26.0% and our total debt and liquidation value of our preferred equity as a percentage of total market capitalization was 27.0% , which was calculated based on the closing price per share of the Company’s common stock of $72.08 on March 31, 2017 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, term loan facility, and unsecured senior notes;


•	Proceeds from our capital recycling program, including the disposition of nonstrategic assets and the formation of strategic ventures;


•	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;


•	Operating 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 and redemptions of outstanding common or preferred stock of the Company; and


•	Outstanding debt repurchases, redemptions and repayments.

General Strategy

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

Liquidity Sources

Unsecured Revolving Credit Facility

The following table summarizes the balance and terms of our unsecured revolving credit facility as of March 31, 2017 and December 31, 2016 :

(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)	The interest rate on our unsecured revolving credit facility is based on an annual rate of LIBOR plus 1.050% .

(3)

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

Capital Recycling Program

As discussed in the section “ Factors That May Influence Future Results of Operations - Capital Recycling Program” we continuously evaluate opportunities for the potential disposition of properties and undeveloped land in our portfolio or the formation of strategic ventures with the intent of recycling the proceeds generated from the disposition of less strategic or lower return assets into capital used to finance development expenditures, to fund new acquisitions, to repay long-term debt and for other general corporate purposes. As part of this strategy, we attempt to enter into Section 1031 Exchanges, when possible, to defer some or all of the taxable gains on the sales, if any, for federal and state income tax purposes.

We currently anticipate that in 2017 we could raise capital through our capital recycling program ranging from approximately $100 million to $300 million, with a midpoint of $200 million, including the operating property disposition we completed in January 2017 for gross proceeds of $12.1 million. Any potential future capital recycling transactions and the timing of any potential future capital recycling transactions will depend on market conditions and other factors, including but not limited to our capital needs and our ability to defer some or all of the taxable gains on the sales. We cannot assure you that we will dispose of any additional properties, enter into any additional strategic ventures, or that we will be able to identify and complete the acquisition of a suitable replacement property to effect a Section 1031 Exchange or be able to use other tax deferred structures in connection with our capital recycling strategy.

At-The-Market Stock Offering Program and January 2017 Common Stock Offering

Since commencement of our at-the-market stock offering program in December 2014, through March 31, 2017 , we have sold 2,459,165 shares of common stock having an aggregate gross sales price of $182.4 million , and approximately $117.6 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, 2017 . Actual future sales will depend upon a variety of factors, including but not limited to, market conditions, the trading price of the Company’s common stock and our capital needs. We have no obligation to sell the remaining shares available for sale under this program.

Shelf Registration Statement

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

Unsecured Senior Notes - Private Placement

On February 17, 2017, the Operating Partnership issued $175.0 million principal amount of its 3.35% Senior Notes, Series A, due February 17, 2027 (the “Series A Notes”), and the $75.0 million principal amount of its 3.45% Senior Notes, Series B, due February 17, 2029 (the “Series B Notes” and, together with the Series A Notes, the “Series A and B Notes”). The Series A and B Notes were issued pursuant to a delayed draw option under a Note Purchase Agreement entered into in connection with a private placement in September 2016. As of March 31, 2017 , there was $175.0 million and $75.0 million issued and outstanding aggregate principal amount of Series A and B Notes, respectively. The Series A Notes mature on February 17, 2027, and the Series B Notes mature on February 17, 2029, unless earlier redeemed or prepaid pursuant to the terms of the Note Purchase Agreement. Interest on the Series A and B Notes is payable semi-annually in arrears on February 17 and August 17 of each year beginning August 17, 2017.

Debt Composition

Refer to our 2016 Annual Report on Form 10-K for our debt composition as of December 31, 2016. There were no material changes to our overall debt composition information including but not limited to secured to unsecured ratios, floating rate to fixed rate ratios, weighted average maturity and weighted average interest rate during the three months ended March 31, 2017 .

Liquidity Uses

Contractual Obligations

Refer to our 2016 Annual Report on Form 10-K for a discussion of our contractual obligations. There have been no material changes, outside of the ordinary course of business, to these contractual obligations during the three months ended March 31, 2017 .

Other Liquidity Uses

Development Activities

As of March 31, 2017 , we had three development projects under construction. These projects have a total estimated investment of approximately $1.1 billion of which we have incurred approximately $481 million and committed an additional $433 million. Additionally, as of March 31, 2017 , approximately $38 million was committed for recently completed development office projects and the completed residential project. In addition, as of March 31, 2017 , we had approximately $9 million in potential future uncommitted tenant costs for two completed and stabilized office projects which may be spent during 2017 depending on leasing activity. Furthermore, we currently believe we may spend an additional $50 - $200 million on potential near-term and future development pipeline projects that we expect we may commence construction on throughout 2017. 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.

Potential Future Acquisitions

As discussed in the section “Factors That May Influence Future Results of Operations - Acquisitions” we continue to evaluate strategic opportunities and remain a disciplined buyer of development and redevelopment opportunities as well as value-add operating properties, dependent on market conditions and business cycles, among other factors, 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, life sciences, entertainment and professional services. 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. 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.

Debt Maturities

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. Our next debt maturity is scheduled to occur in February 2018, at which time there will be a principal payoff amount of $122.9 million . We have the option to prepay without penalty in the fourth quarter of 2017. We also have an additional $325.0 million of unsecured senior notes maturing in July 2018.

6.875% Series G and 6.375% Series H Cumulative Redeemable Preferred Stock

On March 30, 2017, the Company redeemed all 4,000,000 shares of its Series G Preferred Stock. The shares of Series G Preferred Stock were redeemed at a redemption price of $25.00 per share plus accumulated and unpaid dividends for a total cash outflow totaling approximately $100.8 million. We have no further distribution requirements with respect to the Series G Preferred Stock. In connection with the redemption of the Series G Preferred Stock, we incurred an associated non-cash charge of $3.8 million as a reduction to net income available to common stockholders for the related original issuance costs.

The Company has the option to redeem the 4,000,000 shares of its 6.375% Series H Cumulative Redeemable Preferred Stock (“Series H Preferred Stock”), on or after August 15, 2017, in whole or in part at any time or from time to time, by payment of $25.00 per share in cash, totaling $100.0 million plus any accumulated, accrued and unpaid distributions through the date of redemption. Depending on various factors, including but not limited to market conditions, based on our capital needs we currently anticipate that we will redeem all or part of the outstanding Series H Preferred Stock on or after the stated redemption date in 2017. If we redeemed all outstanding Series H Preferred Stock, we would incur an associated non-cash charge of $3.7 million as a reduction to net income available to common stockholders for the related original issuance costs.

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. As of March 31, 2017 , 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, proceeds from the disposition of selective assets through our capital recycling program, and the formation of strategic ventures. 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:


•	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, the Series A and B 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, 2017
Total debt to total asset value	less than 60%	27%
Fixed charge coverage ratio	greater than 1.5x	3.2x
Unsecured debt ratio	greater than 1.67x	3.45x
Unencumbered asset pool debt service coverage	greater than 1.75x	4.27x

Unsecured Senior Notes due 2018, 2020, 2023, 2025 and 2029 (as defined in the applicable Indentures): ⁽¹⁾
Total debt to total asset value	less than 60%	33%
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%	316%

________________________


(1)	Excludes the Unsecured Senior Notes Series A & B due 2027 & 2029 offered through a private placement.

The Operating Partnership was in compliance with all of its debt covenants as of March 31, 2017 . 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 an 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.

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 $18.2 million , or 23.2% , for the three months ended March 31, 2017 compared to the three months ended March 31, 2016 primarily as a result of an increase in cash Net Operating Income generated from our Stabilized Development, Same Store and Acquisition Portfolios. 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. For the three months ended March 31, 2017 , we had net cash used in investing activities of $86.4 million compared to net cash provided by investing activities of $134.2 million for the three months ended March 31, 2016 primarily due to significantly lower disposition activity during the three months ended March 31, 2017 .

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. Our net cash provided by financing activities increased $194.8 million or 635.3% for the three months ended March 31, 2017 compared to the three months ended March 31, 2016 primarily due to proceeds from the January 2017 common stock offering and the funding of the Company’s Series A and B Senior Notes, partially offset by the March 2017 redemption of the Series G Preferred Stock and the January 2017 payment of the special dividend declared in December 2016 during the three months ended March 31, 2017 .

Off-Balance Sheet Arrangements

As of March 31, 2017 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, 2017 and 2016 :
