EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended ~~March 31,~~September 30, 2018 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,~~September 30, 2018, the Company owned an approximate ~~97.9%~~98.0% common general partnership interest in the Operating Partnership. The remaining approximate ~~2.1%~~2.0% common limited partnership interests are owned by non-affiliated investors and certain directors and officers of the Company. As the sole general partner of the Operating Partnership, the Company exercises exclusive and complete discretion over the Operating Partnership’s day-to-day management and control and can cause it to enter into certain major transactions, including acquisitions, dispositions, and refinancings and cause changes in its line of business, capital structure and distribution policies.

There are a few differences between the Company and the Operating Partnership that are reflected in the disclosures in this Form 10-Q. We believe it is important to understand the differences between the Company and the Operating Partnership in the context of how the Company and the Operating Partnership operate as an interrelated, consolidated company. The Company is a REIT, the only material asset of which is the partnership interests it holds in the Operating Partnership. As a result, the Company generally does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing equity from time to time and guaranteeing certain debt of the Operating Partnership. The Company itself is not directly obligated under any indebtedness, but generally guarantees all 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 stockholders’ equity, partners’ capital and noncontrolling interest 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 6, Stockholders’ Equity of the Company;


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


◦	Note ~~12,~~13, Net Income Available to Common Stockholders Per Share of the Company;


◦	Note ~~13,~~14, Net Income Available to Common Unitholders Per Unit of the Operating Partnership;


◦	Note ~~14,~~15, Supplemental Cash Flow Information of the Company; and


◦	Note ~~15,~~16, Supplemental Cash Flow Information of the Operating Partnership;

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


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


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

This report also includes separate sections under Part I, Item 4. Controls and Procedures and separate Exhibit 31 and Exhibit 32 certifications for 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.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1. Organization, Ownership and Basis of Presentation

Organization and Ownership

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 Greater 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.

All of our properties and development projects are 100% owned, excluding four office properties owned by three consolidated property partnerships and ~~an office project~~a development site held by a consolidated variable interest ~~entity~~entities for future transactions intended to qualify as like-kind exchanges pursuant to Section 1031 of the Code (“Section 1031 Exchanges”).

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,~~September 30, 2018, 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,~~September 30, 2018, 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”),~~ 303 Second LLC, 100 First 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,~~ 303 Second LLC, 100 First LLC, Redwood LLC and all of our wholly-owned and controlled subsidiaries. All intercompany balances and transactions have been eliminated in the consolidated financial statements.

As of ~~March 31,~~September 30, 2018, the Company owned an approximate ~~97.9%~~98.0% common general partnership interest in the Operating Partnership. The remaining approximate ~~2.1%~~2.0% common limited partnership interest in the Operating Partnership as of ~~March 31,~~September 30, 2018 was owned by non-affiliated investors and certain of our executive officers and directors. 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. 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, 2018. 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, 2017.

Variable Interest Entities

The Operating Partnership is a variable interest entity (“VIE”) ofthat is consolidated by the Company as the primary beneficiary 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,~~September 30, 2018, the consolidated financial statements of the Company included ~~three~~five VIEs in addition to the Operating Partnership: 100 First LLC, 303 Second LLC and ~~an entity~~three entities established during the ~~first~~second quarter of 2018 to facilitate potential future Section 1031 Exchanges.

primary ~~beneficiaries~~beneficiary of these ~~three~~five VIEs since wethe Operating Partnership had the ability to control the activities that most significantly impact each of the VIE’s economic performance. As of ~~March 31,~~September 30, 2018, the ~~three~~five VIEs’ total assets, liabilities and noncontrolling interests included on our consolidated balance sheet were approximately ~~$543.5~~$828.3 million (of which ~~$489.4~~$753.8 million related to real estate held for investment), approximately ~~$31.5~~$86.2 million and approximately ~~$177.2~~$187.6 million, respectively. Revenues, income and net assets generated by 100 First LLC and 303 Second LLC may only be used to settle their contractual obligations, which primarily consist of operating expenses, capital expenditures and required distributions.

~~KILROY REALTY CORPORATION AND KILROY REALTY, L.P.~~

~~NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)~~

At December 31, 2017, the consolidated financial statements of the Company and the Operating Partnership included two VIEs in which we were deemed to be the primary beneficiary: 100 First LLC and 303 Second LLC. At December 31, 2017, the impact of consolidating the VIEs increased the Company’s total assets, liabilities and noncontrolling interests on our consolidated balance sheet by approximately $426.5 million (of which $382.1 million related to real estate held for investment), approximately $27.3 million and approximately $175.4 million, respectively.

Accounting Pronouncements Adopted January 1, 2018

Effective January 1, 2018, we adopted Financial Accounting Standards Board (“FASB”) ASU No. 2014-09 “Revenue From Contracts with Customers (Topic 606)” (“ASU 2014-09”) and the related FASB ASU Nos. 2016-12 and 2016-20, which provide practical expedients, technical corrections, and improvements for certain aspects of ASU 2014-09, on a modified retrospective basis. ASU 2014-09 establishes a single comprehensive model for entities to use in accounting for revenue from contracts with customers and supersedes most of the existing revenue recognition guidance.

We evaluated each of the Company’s revenue streams to determine the sources of revenue that are impacted by ASU 2014-09 and concluded that two revenue streams, sales of real estate and revenue from our multi-tenant parking arrangements, fall within the scope of Topic 606. We evaluated the impact of the adoption of the guidance on the timing of gain recognition for our historical dispositions and concluded there was no significant impact to our consolidated financial statements given the ~~simplicity and~~ straight forward nature of our historical disposition transactions. We also evaluated the impact of the guidance on the timing and pattern of revenue recognition for our multi-tenant parking arrangements and determined there was no significant impact to our consolidated financial statements. We generally provide parking for our multi-tenant properties based on the prevailing market rate per parking space, which adjusts based on prevailing market rates during the tenant’s occupancy, and we recognize parking revenue as parking spaces are utilized by the tenant. Given the structure of these arrangements whereby the amount of parking revenue we recognize corresponds directly to the tenant’s use, we were able to apply the practical expedient provided in Accounting Standards Codification (“ASC”) 606-10-50-14(b) (the “right to invoice” practical expedient). As a result of applying this practical expedient, we are not required to disclose the transaction price allocated to future performance obligations for multi-tenant parking since we cannot predict or estimate the use of such parking spaces. During the three months ended ~~March 31,~~September 30, 2018 and 2017, we recognized $6.7 million and $6.6 million, respectively, of parking revenue for arrangements that are within the scope of Topic 606, which is included in rental revenues on our consolidated statements of operations. During the nine months ended September 30, 2018 and ~~$6.7~~2017, we recognized$20.2 millionand $20.3 million, respectively, of parking revenue for arrangements that are within the scope of Topic 606, which is included in rental revenues on our consolidated statements of operations. We concluded that the adoption of Topic 606 did not have ana material impact on our consolidated financial statements or a material impact on the notes to our consolidated financial statements.

Effective January 1, 2018, we adopted FASB ASU No. 2017-09 “Compensation - Stock Compensation (Topic 718)” on a prospective basis. Under the guidance, an entity will not apply modification accounting to a share-based payment award if the award’s fair value, vesting conditions, and classification as an equity or liability instrument remain the same immediately before and after the change. The adoption of this guidance did not have an impact on our consolidated financial statements or notes to our consolidated financial statements.

Effective January 1, 2018, we adopted FASB ASU No. 2017-05 “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20)” (“ASU 2017-05”) on a retrospective basis. This standard clarifies 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 nonfinancial assets in transactions with noncustomers. Additionally, ASU 2017-05 adds guidance pertaining to the partial sales of real estate and clarifies that nonfinancial assets within the scope of ASC 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. We evaluated the impact of the new amendments on our historical transactions and concluded that there was no impact. As such, the adoption of this guidance did not have an impact on our consolidated financial statements or notes to our consolidated financial statements.

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Effective January 1, 2018, we adopted FASB ASU No. 2016-15 (“ASU 2016-15”) which provides guidance where there is diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows, on a retrospective basis. The adoption of this guidance did not have an impact on our consolidated financial statements or notes to our consolidated financial statements.

Effective January 1, 2018, we adopted FASB ASU No. 2016-01 (“ASU 2016-01”) which amends the accounting guidance on the classification and measurement of financial instruments and FASB ASU No. 2018-03 (“ASU 2018-03”) which provides technical corrections and improvements to ASU 2016-01, on a modified retrospective basis. The amendments require that all investments in equity securities, including other ownership interests, are reported at fair value with changes in fair value reported

~~KILROY REALTY CORPORATION AND KILROY REALTY, L.P.~~

~~NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)~~

in 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 amendments require that the portion of the total fair value change caused by a change in instrument-specific credit risk for financial liabilities for which the fair value option has been elected would be recognized in other comprehensive income. Any accumulated amount remaining in other comprehensive income is reclassified to earnings when the liability is extinguished. The adoption of this guidance did not have an impact on our consolidated financial statements or notes to our consolidated financial statements since our only financial instruments within the scope of ASU 2016-01 and 2018-03 are the marketable securities related to our deferred compensation plan which are classified as trading securities and marked to market at fair value through earnings each reporting period.

Accounting Pronouncements Effective January 1, 2019

ASU No. 2016-02 “Leases (Topic 842)”

On February 25, 2016, the FASB issued ASU No. 2016-02 “Leases (Topic 842)” (“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. Early adoption is permitted. We continue to have an active project team, led by senior accounting management, that is proactively working to analyze and evaluate the impact of the guidance on our consolidated financial statements.

In ~~January~~July 2018, the FASB ~~released an exposure draft to amend~~issued ASU No. ~~2016-02 that would~~2018-11 which (1) ~~simplify~~simplifies transition requirements for both lessees and lessors by adding an option that ~~would permit~~permits an organization to apply the transition provisions of the new standard at its adoption date instead of at the earliest comparative period presented in its financial statements and (2) ~~provide~~provides a practical expedient for lessors that ~~would permit~~permits lessors to make an accounting policy election to not separate nonlease components from the associated lease components, ~~if certain criteria are met.~~

In March 2018, the FASB decided to finalize the changes with respect to optional transition relief and approved a practical expedient for lessors that would permit lessors to make an accounting policy election to not separate nonlease components from the associated lease components, by class of underlying asset, if the following two criteria are met: (1) the timing and pattern of transfer of the lease and nonlease components are the same and (2) the lease component would be classified as an operating lease if accounted for separately. For leases where we are the lessor, we ~~currently believe that we will~~plan to elect the optional transition relief and ~~that we will meet~~apply the ~~noted criteria to not be required to bifurcate and separately report nonlease components, such as common area maintenance revenue, for operating leases on our consolidated statements of operations.~~practical expedients provided by ASU 2018-11. As a result, ~~we currently believe that~~ leases where we are the lessor will be accounted for in a similar method to existing standards with the underlying leased asset being reported and recognized as a real estate asset. ~~The~~

In August 2018, the FASB ~~is expected~~released an exposure draft to ~~issue an Accounting Standards Update codifying these changes in the coming months. We currently expect to adopt~~amend ASU 2016-02 ~~using~~that clarifies lessor treatment of sales taxes and other similar taxes collected from lessees, lessor costs paid directly by lessees and recognition of variable payments for contracts with lease and nonlease components. If the ~~practical expedients proposed in~~amendments are codified as currently drafted, we do not expect the ~~standard and the changes approved by the FASB.~~amendments to have an impact on our consolidated financial statements.

ASU 2016-02 also specifies that upon adoption, lessors will no longer be able to capitalize and amortize certain leasing related costs and instead will only be permitted to capitalize and amortize incremental direct leasing costs. As a result, we have concluded that upon the adoption of the standard, we will be required to expense as incurred certain leasing costs we are currently able to capitalize and amortize as deferred leasing costs under existing guidance. We ~~are currently in the process of analyzing~~continue to evaluate the impact of this change in the guidance and we currently ~~believe~~expect this change will have a material impact to the Company’s consolidated financial statements and results of operations upon adoption of the ~~standard.~~standard on January 1, 2019.

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. ~~We currently believe that existing~~Existing ground leases executed before the January 1, 2019 adoption date will continue to be accounted for as operating leases and the new guidance will not have a material impact on our recognition of ground lease expense or our results of operations.

containing provisions for rental payments to fluctuate based on fair market value and operating 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 financing type leases, 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.

Accounting Pronouncements Effective in 2020 and Beyond

ASU No. 2016-13 “Financial Instruments - Credit Losses (Topic 326)”

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. In August 2018, the FASB released an exposure draft to amend ASU 2016-03. The proposed amendment would clarify that receivables arising from operating leases are not within the scope of Subtopic 326-20 “Financial Instruments – Credit Losses.” Instead, impairment of receivables arising from operating leases should be accounted for under Subtopic 842-30 “Leases – Lessor.” 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~~the consolidated financial statements or notes to ~~our~~the consolidated financial statements.

ASU No. 2018-13 “Fair Value Measurement (Topic 820)”

On August 28, 2018, the FASB issued ASU No. 2018-13 (“ASU 2018-13”) to amend the disclosure requirements for fair value measurements. The amendments in ASU 2018-13 include new, modified and eliminated disclosure requirements and are the result of a broader disclosure project called FASB Concepts Statement, Conceptual Framework for Financial Reporting - Chapter 8: Notes to Financial Statements, which the Board finalized on August 28, 2018. The Board used the guidance in the Concepts Statement to improve the effectiveness of ASC 820’s disclosure requirements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for any eliminated or modified disclosures. The Company currently anticipates that the guidance will not have a significant impact on the disclosures in the notes to the consolidated financial statements.

ASU No. 2018-15 “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40)”

On August 29, 2018, the FASB issued ASU No. 2018-15 (“ASU 2018-15”) to amend a customer’s accounting for implementation costs incurred in a cloud computing arrangement that is a service contract. ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. ASU 2018-15 can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is currently evaluating the impact of ASU 2018-15 on the consolidated financial statements and notes to the consolidated financial statements.

Debt Covenants and Restrictions

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

6. Stockholders’ Equity of the Company

Forward Equity Offering

On August 8, 2018, the Company entered into forward equity sale agreements with certain financial institutions acting as forward purchasers in connection with an offering of5,000,000 common shares at an initial gross offering price of $360.5 million, or $72.10 per share, before underwriting discounts, commissions and offering expenses. The forward purchasers borrowed and sold an aggregate of 5,000,000 shares in the offering. The Company did not receive any proceeds from the sale of its common shares by the forward purchasers in the offering. The Company currently expects to fully physically settle the forward sale agreements and receive cash proceeds upon one or more settlement dates, at the Company’s discretion, prior to the final settlement date under the forward sale agreements of August 1, 2019. The forward sale price that we expect to receive upon physical settlement of the agreements will be subject to adjustment for (i) the forward purchasers’ stock borrowing costs and (ii) scheduled dividends during the term of the agreements. The full amount of this offering remains available for future settlement as of the date of this filing. Upon issuance of shares, the Company will contribute the net proceeds from these issuances to the Operating Partnership in exchange for an equal number of units in the Operating Partnership.

At-The-Market Stock Offering Program

~~Under our current~~In May 2018, the Company completed its then existing at-the-market stock offering program, under which we sold an aggregate of $300.0 million in gross sales of shares. In June 2018, the Company commenced ~~in December 2014,~~a new at-the-market stock offering program (the “2018 At-The-Market Program”), under which we may currently offer and sell shares of our common stock ~~having~~with an aggregate gross sales price of up to ~~$300.0 million~~$500.0 million. In connection with the 2018 At-The-Market-Program, the Company also entered into related forward purchase agreements whereby, at our discretion, we may sell shares of our common stock under the 2018 At-The-Market-Program under forward equity sale agreements. The use of a forward equity sale agreement would allow the Company to lock in a share price on the sale of shares of our common stock at the time the agreement is executed, but defer receiving the proceeds from the sale of shares until a later date. This also allows us to defer the potential dilutive impact of such offering of shares until such time ~~to time~~as we settle the forward equity sale agreements.

Since commencement of our 2018 At-The-Market Program in ~~“at-the-market” offerings. No~~ June 2018, we have sold447,466shares of common stock through September 30, 2018, none of which were sold under this program during the three months ended March 31, 2018. Since commencement of the program through March 31, 2018, we have sold 2,694,242 shares of common stock having an aggregate gross sales price of $200.1 million. As of March 31, 2018, shares of common stock having an aggregate gross sales price of up to $99.9forward equity sale agreements. Approximately$466.2 million ~~remain~~remains available to be sold under this program.

The following table sets forth information regarding sales of common stock under our at-the-market offering programs for the nine months ended September 30, 2018:



	Nine Months Ended September 30, 2018

Shares of common stock sold during the period	1,817,195
Weighted average price per common share	$	73.64
Aggregate gross proceeds	$	133.8
Aggregate net proceeds after selling commissions	$	132.1

The proceeds from sales were used to fund acquisitions, development expenditures and general corporate purposes. 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.

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 ~~$146.1~~$143.4 millionand $154.5 million as of ~~March 31,~~September 30, 2018 and December 31, 2017, 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.

9. Share-Based Compensation

Stockholder Approved Equity Compensation Plans

As of ~~March 31,~~September 30, 2018, we maintained one share-based incentive compensation plan, the Kilroy Realty 2006 Incentive Award Plan, as amended (the “2006 Plan”). As of ~~March 31,~~September 30, 2018, approximately 1.8 million 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 or market 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.

2018 Share-Based Compensation Grants

In January and February 2018, the Executive Compensation Committee of the Company’s Board of Directors awarded 282,038 restricted stock units (“RSUs”) to certain officers of the Company under the 2006 Plan, which included 158,205 RSUs (at the target level of performance) that are subject to market and/or performance-based vesting requirements (the “2018 Performance-Based RSUs”) and 123,833 RSUs that are subject to time-based vesting requirements (the “2018 Time-Based RSUs”).

2018 Performance-Based RSU Grant

The 2018 Performance-Based RSUs are scheduled to vest at the end of a three-year period (consisting of calendar years 2018-2020). A target number of 2018 Performance-Based RSUs were awarded, and the final number of 2018 Performance-Based RSUs that vest (which may be more or less than the target number) will be based upon (1) the achievement of pre-set FFO per share goals for the year ending December 31, 2018 that applies to 100% of the Performance-Based RSUs awarded (the “FFO performance condition”) and (2) a performance measure that applies to 50% of the award based upon a measure of the Company’s average debt to EBITDA ratio for the three-year performance period (the “debt to EBITDA ratio performance condition”) and a market measure that applies to the other 50% of the award based upon the relative ranking of the Company’s total stockholder return for the three-year performance period compared to the total stockholder returns of an established comparison group of companies over the same period (the “market condition”). The 2018 Performance-Based RSUs are also subject to a three-year service vesting provision and are scheduled to cliff vest on the date the final vesting percentage is determined following the end of the three-year performance period under the awards. The number of 2018 Performance-Based RSUs ultimately earned could fluctuate from the target number of 2018 Performance-Based RSUs granted based upon the levels of achievement for the FFO performance condition, the debt to EBITDA ratio performance condition, the market condition, and the extent to which the service vesting condition is satisfied. The estimate of the number of 2018 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,~~September 30, 2018, the number of 2018 Performance-Based RSUs estimated to be earned based on the Company’s estimate of the performance conditions measured against the applicable goals was ~~158,205,~~180,931, and the compensation cost recorded to date for this program was based on that estimate. Compensation expense for the 2018 Performance-Based RSU grant ~~will be recorded~~is recognized on a straight-line basis over the requisite service period for each participant, which is generally the three-year service period.

~~KILROY REALTY CORPORATION AND KILROY REALTY, L.P.~~

~~NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)~~

Each 2018 Performance-Based RSU represents the right, subject to the applicable vesting conditions, to receive one share of our common stock in the future. The determination of the grant date fair value of the portion of the 2018 Performance-Based RSU grants covered by the debt to EBITDA ratio performance condition was based on the $66.46 share price on the grant date. The determination of the grant date fair value of the portion of the 2018 Performance-Based RSU grants covered by the market condition was calculated using a Monte Carlo simulation pricing model based on the assumptions in the table below, which resulted in a $70.08 grant date fair value per share.



	Fair Value Assumptions
Expected share price volatility	20.00%
Risk-free interest rate	2.37%
Expected life	2.9 years

The computation of expected volatility is based on a blend of the historical volatility of our shares of common stock over approximately 5.8 years, as that is expected to be most consistent with future volatility and equates to a time period twice as long as the approximate 2.9-year 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 14, 2018. The expected life of the 2018 Performance-Based RSUs is equal to the remaining 2.9-year vesting period as of February 14, 2018.

The total grant date fair value of the 2018 Performance-Based RSU awards was $10.8 million on the February 14, 2018 grant date of the awards. For the ~~three~~nine months ended ~~March 31,~~September 30, 2018, we recorded compensation expense based upon the grant date fair value per share for each component multiplied by the estimated number of RSUs to be earned as discussed above.

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

2018 Time-Based RSU Grant

The 2018 Time-Based RSUs are scheduled to vest in three equal annual installments beginning on January 5, 2019 through January 5, 2021. Compensation expense for the 2018 Time-Based RSUs ~~will be~~is recognized on a straight-line basis over the requisite service period for each participant, which is generally the three-year service vesting period. Each 2018 Time-Based RSU represents the right to receive one share of our common stock in the future. The total grant date fair value of the 2018 Time-Based RSU awards was $8.4 million, which was based on the $70.37 and $66.46 closing share prices of the Company’s common stock on the NYSE on the January 29, 2018 and February 14, 2018, respectively, grant dates of the awards.

Share-Based Compensation Cost Recorded During the Period

The total compensation cost for all share-based compensation programs was ~~$5.1~~$8.1 million and ~~$6.2~~$6.4 million for the three months ended ~~March 31,~~September 30, 2018 and 2017, respectively, and $24.7 million and $19.0 million for the nine months ended September 30, 2018 and 2017, respectively. Of the total share-based compensation costs, $1.5 million and ~~$2.0~~$1.7 million was capitalized as part of real estate assets and deferred leasing costs for the three months ended ~~March 31,~~September 30, 2018 and 2017, respectively, and $5.8 million and $5.4 million for the nine months ended September 30, 2018 and 2017, respectively. As of ~~March 31,~~September 30, 2018, there was approximately ~~$41.3~~$24.3 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 ~~2.2~~1.8 years. The remaining compensation cost related to these nonvested incentive awards had been recognized in periods prior to ~~March 31,~~September 30, 2018.

10. Commitments and Contingencies

General

As of ~~March 31,~~September 30, 2018, we had commitments of approximately ~~$748.4~~$776.5 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,

~~KILROY REALTY CORPORATION AND KILROY REALTY, L.P.~~

~~NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)~~

we are not currently aware of any environmental liability with respect to our stabilized portfolio properties that would have a material adverse effect on our financial condition, results of operations and cash flow, or that we believe would require additional disclosure or the recording of a loss contingency.

As of ~~March 31,~~September 30, 2018, we had accrued environmental remediation liabilities of approximately ~~$28.2~~$79.6 million recorded on our consolidated balance sheets in connection with certain of our in-process and future development projects. The accrued environmental remediation liabilities represent the remaining costs we estimate we will incur when we commence development at various development acquisition sites. These estimates, which we developed with the assistance of third party experts, consist primarily of the removal of contaminated soil and other related costs since we are required to dispose of any existing contaminated soil when we develop new properties at these sites.

We record estimated environmental remediation obligations for acquired properties at the acquisition date when we are aware of such costs and when such costs are probable of being incurred and can be reasonably estimated. Estimated costs related to development environmental remediation liabilities are recorded as an increase to the cost of the development project. Actual costs are recorded as a decrease to the liability when incurred. These accruals are adjusted as an increase or decrease to the development project costs and as an increase or decrease to the accrued environmental remediation liability if we obtain further information or circumstances change. The environmental remediation obligation recorded at September 30, 2018 was not discounted to its present value since we expect to complete the remediation activities in the next one to five years in connection with development activities at the various sites. It is possible that we could incur additional environmental remediation costs in connection with these future development projects. However, given we are in the pre-development phase on these future development projects, potential additional environmental costs cannot be reasonably estimated at this time and certain changes in estimates could occur as the site conditions, final project timing, design elements, actual soil conditions and other aspects of the projects, which may depend upon municipal and other approvals beyond the control of the Company, are determined.

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Other than the accrued environmental liabilities discussed above, we are not aware of any unasserted claims and assessments with respect to an environmental liability that we believe would require additional disclosure or the recording of an additional loss contingency.

11. Fair Value Measurements and Disclosures

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 gain/loss 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 ~~(loss)~~ gain on marketable securities recorded during the three and nine months ended ~~March 31,~~September 30, 2018 and 2017:

12. Other Significant Events

During the nine months ended September 30, 2018, we recognized $6.7 million of provision for bad debts. The provision for bad debts is primarily due to a $7.0 million increase in the provision for one tenant recognized during the second quarter of 2018.

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 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, resolution of our discussions with tenants on our internal watch list, 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, our ability to re-lease properties at or above current market rates, 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 re-lease property at or above current market rates; costs to comply with government regulations, including environmental remediation; 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, as well as business and consumer reactions to such changes; 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, 2017 and their respective other filings with the SEC. All forward-looking statements are based on information that was available and speak only as of the date on which they were made. We assume no obligation to update any forward-looking statement that becomes untrue because of

subsequent events, new information or otherwise, except to the extent we are required to do so in connection with our ongoing requirements under federal securities laws.

Overview and Background

We are a self-administered REIT active in premier office 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 Greater Los Angeles, Orange County, San Diego County, the San Francisco Bay Area and Greater Seattle, which we believe have strategic advantages and strong barriers to entry. We own our interests in all of our properties through the Operating Partnership and the Finance Partnership and generally conduct substantially all of our operations through the Operating Partnership. We owned an approximate 98.0%, 97.9%, and 97.9% general partnership interest in the Operating Partnership as of ~~March 31,~~September 30, 2018, December 31, 2017 and ~~March 31,~~September 30, 2017. 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 and, subject to market conditions, executing on our future development pipeline, including expanding entitlements. Over the past several years, we increased our focus on development opportunities and expanded our future development pipeline through targeted acquisitions of development opportunities on the West Coast. This includes the acquisition of a 39-acre development site in South San Francisco, California on June 1, 2018 for a cash purchase price of approximately $308.2 million as discussed in “– Acquisitions” below.

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 and we generally favor starting projects with pre-leasing activity, as appropriate.

In-Process Development Projects - Tenant Improvement

During the nine months ended September 30, 2018, the following two development projects were moved from the under construction phase to the tenant improvement phase:

100 Hooper, SOMA, San Francisco, California, which we acquired in July 2015 and commenced construction on in November 2016. This project encompasses approximately 312,000 square feet of office and approximately 88,000 square feet of production, distribution and repair (“PDR”) space configured in two buildings with a total estimated investment of approximately $270.0 million. The office portion of the project is 100% pre-leased to Adobe Systems Inc. and the PDR space is38% leasedas of the date of this report. We commenced revenue recognition on the lease with Adobe Systems Inc. on October 1, 2018 and cash rents will commence in the first quarter of 2019 through the second quarter of 2020. The project is currently expected to be stabilized in the second quarter of 2019.

The Exchange on 16th, Mission Bay, San Francisco, California, which we acquired in May 2014 and commenced construction on in June 2015. This project will encompass approximately 750,000 gross rentable square feet consisting of 736,000 square feet of office space and 14,000 square feet of retail space at a total estimated investment of $570.0 million. The office space in the project is 100% pre-leased to Dropbox, Inc. The lease with Dropbox, Inc. will commence in phases beginning in the fourth quarter of 2018 through the fourth quarter of 2019 with cash rents commencing in the third quarter of 2019 through the first quarter of 2020.

Future Development Pipeline

As of ~~March 31,~~September 30, 2018, our future development pipeline included ~~six~~seven future projects located in the San Francisco Bay Area, Greater Los Angeles and San Diego County with an aggregate cost basis of approximately ~~$561.1~~$868.7 million at which we believe we could develop from ~~3.8~~5.5 million rentable square feet to ~~4.3~~6.5 million rentable square feet atfor a total estimated investment of ~~$2.8~~$5.0 billion to ~~$3.3~~$6.0 billion, depending on successfully obtaining entitlements and market conditions.

________________________


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


(2)	Represents cash paid and costs incurred, including accrued liabilities in accordance with GAAP, as of ~~March 31,~~September 30, 2018.


~~(3)~~	~~Development for this project will occur in phases. Phases II and III, comprised of residential and office, respectively, will commence subject to market conditions and economic factors.~~

Fluctuations in our development activities could cause fluctuations in the average development asset balances qualifying for interest and other carrying cost and internal cost capitalization in future periods. During the three and nine months ended ~~March 31,~~September 30, 2018, ~~and 2017,~~ we capitalized interest on in-process development projects and development pipeline projects with an average aggregate cost basis of approximately ~~$1.3~~$1.8 billion and $1.5 billion, respectively, asit was determined these projects qualified for interest and other carrying cost capitalization under GAAP. During the three and nine months ended September 30, 2017, we capitalized interest on in-process development projects and future development pipeline projects with an average aggregate cost basis of approximately $1.0 billion, ~~respectively,~~ as it was determined these projects qualified for interest and other carrying cost capitalization under GAAP. For the three and nine months ended ~~March 31,~~September 30, 2018, we capitalized $19.2 million and $48.5 million,

respectively, of interest to our qualifying development projects. For the three and nine months ended September 30, 2017, we capitalized ~~$13.6~~$12.2 million and ~~$10.2~~$33.1 million, respectively, of interest to our qualifying development projects. For the three and nine months ended ~~March 31,~~September 30, 2018, ~~and 2017,~~ we capitalized ~~$6.4~~$5.3 million and ~~$5.7~~$18.6 million, respectively, of internal costs to our qualifying development projects. For the three and nine months ended September 30, 2017, we capitalized $4.9 million and $15.7 million, respectively, of internal costs to our qualifying development projects.

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. See the “Liquidity and Capital Resources of the Operating Partnership – Liquidity Sources” section for further discussion of the program.

The timing of any potential future disposition or strategic venture transactions will depend on market conditions and other factors, including but not limited to our capital needs and our ability to defer some or all of the taxable gains on the sales. We cannot assure that we will dispose of any additional properties, 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 strategy.

Acquisitions. During the ~~three~~nine months ended ~~March 31,~~September 30, 2018, we acquired three office buildings in South San Francisco, California for a purchase price of $111.0 million. In addition, we separately acquired a 39-acre development site adjacent to these office buildings for a cash purchase price of approximately $308.2 million from an unrelated seller.

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 or strategic 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.

In connection with our growth strategy, we often have one or more potential acquisitions of properties and/or undeveloped land under consideration that are in varying stages of negotiation and due diligence review, or under contract, at any point in time. However, we cannot provide assurance that we will enter into any agreements to acquire those properties or undeveloped land or, if we do, that those 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. As of ~~March 31,~~September 30, 2018, we had ~~$41.0~~nonrefundable deposits of $15.0 million related to the future acquisition of ~~acquisition deposits~~an operating property with a purchase price of $146.0 million that ~~were nonrefundable, subject~~is currently expected to ~~closing conditions required to be met by the seller.~~close in December 2018.

Incentive Compensation. Our Executive Compensation Committee determines compensation, including cash bonuses and equity incentives, for our executive officers. For 2018, 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,~~September 30, 2018, there was approximately ~~$41.3~~$24.3 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 ~~2.2~~1.8 years. The ~~$41.3~~$24.3 million of unrecognized compensation cost is subject to fluctuation based on the ultimate outcome of performance measures for awards that are still in the performance period and also does not reflect the future compensation cost for any potential share-based awards that may be issued subsequent to ~~March 31,~~September 30, 2018. 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 and nine months ended ~~March 31,~~September 30, 2018.

For the nine months ended September 30, 2018, 35 leases totaling 783,649 rentable square feet were signed but not commenced as of September 30, 2018.


(10)	Excludes a 110,000 square foot lease executed at a property located San Francisco that the Company expects to acquire by the end of 2018.

As of ~~March 31,~~September 30, 2018, we believe that the weighted average cash rental rates for our total stabilized portfolio are approximately ~~10-15%~~19% 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 5-10% 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 tables set forth certain information regarding our lease expirations for our stabilized portfolio for the remainder of 2018 and the next five years and by region for the remainder of 2018 and in 2019.

(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,~~September 30, 2018, space leased under month-to-month leases, storage leases, vacant space and future lease renewal options not executed as of ~~March 31,~~September 30, 2018.

(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.”


(3)	Includes 100% of annualized base rent of consolidated property partnerships.


(4)	Adjusting for leases executed as of September 30, 2018 but not yet commenced, the remaining 2018 and 2019 expirations would be reduced by 93,993 square feet and 598,491 square feet, respectively.

In addition to the ~~0.8~~0.9 million rentable square feet, or ~~5.7%~~6.5%, of currently available space in our stabilized portfolio, leases representing approximately ~~6.5%~~2.4% and ~~11.8%~~11.5% of the occupied square footage of our stabilized portfolio are scheduled to expire during the remainder of 2018 and in 2019, respectively. The leases scheduled to expire during the remainder of 2018 and in 2019 represent approximately ~~2.4~~1.8 million rentable square feet or ~~17.1%~~12.7% 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. 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 approximately ~~0.8~~0.3 million rentable square feet or ~~6.7%~~2.1% of our total annualized base rental revenue scheduled to expire during the remainder of 2018, we believe that the weighted average cash rental rates ~~for our overall portfolio~~ are approximately ~~at current average market rental rates, except in our San Francisco and San Diego submarkets where we currently believe these expiring leases are approximately 25%~~5% below ~~market and 25% above market, respectively.~~market.

For the approximately 1.5 million rentable square feet or ~~10.4%~~10.6% of our total annualized base rental revenue scheduled to expire in 2019 we believe that the weighted average cash rental rates ~~for our~~are overall ~~portfolio are~~ approximately 20% below current average market rental rates, primarily due to our Los Angeles and San Francisco submarkets where we currently believe these expiring leases are approximately 20% below market and ~~30%~~35% below market, respectively.

Stabilized Portfolio Information

As of ~~March 31,~~September 30, 2018, our stabilized portfolio was comprised of 104 office properties encompassing an aggregate of approximately 13.9 million rentable square feet and 200 residential units at our residential tower in Hollywood, California. Our stabilized portfolio includes all of our properties with the exception of development and redevelopment properties currently committed for construction, under construction, or ~~committed for construction, “lease-up” properties,~~in the tenant improvement phase, undeveloped land and real estate assets held for ~~sale and undeveloped land.~~sale. 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 in the tenant improvement phase as ~~office~~properties that we are developing or redeveloping where the project has reached cold shell condition and ~~retail properties we recently developed or redeveloped that have not yet reached~~is ready for tenant improvements, which may require additional major base building construction before being placed in service. Projects in the tenant improvement phase are added to our stabilized portfolio once the project reaches the earlier of 95% occupancy ~~and are within~~or one year ~~following~~from the date of the cessation of major base building construction activities. Costs capitalized to construction in progress for development and redevelopment properties are transferred to land and improvements, buildings and improvements, and deferred leasing costs on our consolidated balance sheets as the historical cost of the property as the projects are placed in service.

We did not have any ~~“lease-up”,~~ redevelopment or held for sale properties at ~~March 31,~~September 30, 2018. Our stabilized portfolio also excludes our future development pipeline, which as of ~~March 31,~~September 30, 2018 was comprised of ~~six~~seven potential development sites, representing approximately 4680 gross acres of undeveloped land on which we believe we have the potential to develop from ~~3.8~~5.5 million rentablesquare feet to ~~4.3~~6.5 million rentable square feet, 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 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, 2017 and still owned and included in the stabilized portfolio as of ~~March 31,~~September 30, 2018, including our residential tower in Hollywood, California;

Stabilized Development Properties – includes the results generated by the one office development project that was added to the stabilized portfolio in the first quarter of 2017;

Acquisition Properties – includes the results, from the dates of acquisition through the periods presented, for the three office buildings we acquired in January 2018; and

Dispositions and Other Properties – includes the results of the ten properties disposed of in the third quarter of 2017, the one property disposed of during the first quarter of 2017 and expenses for certain of our in-process and future development projects.

The following table sets forth certain information regarding the property groups within our stabilized office portfolio as of ~~March 31,~~September 30, 2018:

$2.8 million increase in the provision for bad debts primarily due to a $7.0 million increase in the provision for one tenant (see further discussion below), partially offset by a $1.4 million reversal of a straight line rent reserve for one tenant resulting from the assignment of its lease to a credit tenant and a net $2.8 million decrease in the provision based on our evaluation of outstanding receivables at the end of each period;

An increase of $3.0 million attributable to the Stabilized Development Properties primarily due to the following:

$4.0 million increase in rental income and a $0.3 million increase in tenant reimbursements resulting from full occupancy in 2018 compared to partial occupancy in 2017;

$0.5 million decrease in real estate taxes primarily due to adjustments in 2018 resulting from favorable timing of supplemental tax assessments; offset by

$0.7 million increase in property expenses resulting from full occupancy in 2018 compared to partial occupancy in 2017; and

$1.2 million increase in the provision for bad debts due to a provision recorded for one tenant;

An increase of $4.3 million attributable to the Acquisition Properties; partially offset by

A decrease of $10.9 million attributable to the Dispositions & Other Properties.

As noted above and previously disclosed, during the nine months ended September 30, 2018, we recorded a $7.0 million increase in the provision for bad debts related to one tenant based on our discussions with this tenant and consistent with our accounting policies. As of September 30, 2018, our lease with this tenant represented approximately 1% of our total annualized base rental revenues. We cannot provide any assurance that any of this tenant’s lease or other obligations payable to us will not be reduced or, possibly, extinguished as a result of future discussions with this tenant or that our evaluation of other factors (including future increases in current tenant receivables and deferred rent receivables) will not result in us recording a further incremental provision for bad debts with respect to this tenant in the future.

Other Expenses and Income

General and Administrative Expenses

General and administrative expenses increased $12.8 million, or 29.4%, for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017 primarily due to the following:

An increase of approximately $5.2 million resulting from higher professional service costs primarily related to legal costs incurred in connection with a previously disclosed litigation matter; and

An increase of approximately $7.6 million due to higher stock compensation amortization as well as higher compensation and office expenses related to the growth of the Company.

Interest Expense



	Nine Months Ended September 30,
	2018			2017			Dollar Change			Percentage Change
	(in thousands)
Gross interest expense	$	85,834		$	84,577		$	1,257		1.5	%

Interest expense	$	37,285		$	51,476		$	(14,191	)	(27.6	)%

Gross interest expense, before the effect of capitalized interest and deferred financing costs, increased $1.3 million or 1.5% for the nine months ended September 30, 2018 as compared to the nine months ended September 30, 2017 due to an increase in our weighted average debt balance for the nine months ended September 30, 2018.

Capitalized interest and deferred financing costs increased $15.4 million or 46.7%, for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017 primarily due to an increase in the average development asset balances qualifying for interest capitalization for the nine months ended September 30, 2018. During the nine months ended September 30, 2018 and 2017, we capitalized interest on in-process development projects and future development pipeline projects with an average aggregate cost basis of approximately $1.5 billion and $1.0 billion, respectively.

Net Income Attributable to Noncontrolling Interests in Consolidated Property Partnerships

Net income attributable to noncontrolling interests in consolidated property partnerships increased $1.5 million or 15.7% for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017 due to the inclusion of interest expense in 2017 for a mortgage note secured by one of the properties held by the property partnerships that was repaid in the fourth quarter of 2017. The amounts reported for the nine months ended September 30, 2018 and 2017 are comprised of the noncontrolling interests’ share of net income for 100 First LLC, 303 Second LLC and 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 common stockholders for the next twelve months. Cash flows from operating activities generated by the Operating Partnership for the ~~three~~nine months ended ~~March 31,~~September 30, 2018 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 throughout 2018. 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 property dispositions, the Company may elect to distribute a special dividend to its common stockholders and common unitholders in order to minimize or eliminate 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 is consistent with the Company’s ~~intention to maintain~~

3642

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 14,~~September 5, 2018, the Board of Directors declared a regular quarterly cash dividend of ~~$0.425~~$0.455 per share of common ~~stock~~stock. The regular quarterly cash dividend is payable to stockholders of record on ~~March 29,~~September 28, 2018 and ~~caused~~ a ~~$0.425~~corresponding cash distribution of $0.455 per Operating Partnership ~~unit cash distribution~~units is payable to ~~be paid in respect~~holders of the Operating Partnership’s common limited partnership interests of record on September 28, 2018, including those owned by the Company. The total cash quarterly dividends and distributions paid on ~~April 18,~~October 17, 2018 were ~~$42.9~~$46.8 million.

Debt Covenants

The covenants contained within certain of our unsecured debt obligations generally prohibit the Company from paying dividends during an event of default in excess of an amount which results in distributions to us in an amount sufficient to permit us to pay dividends to our stockholders that we reasonably believe are necessary to (a) maintain our qualification as a REIT for federal and state income tax purposes and (b) avoid the payment of federal or state income or excise tax.

Capitalization

As of ~~March 31,~~September 30, 2018, our total debt as a percentage of total market capitalization was ~~26.4%~~28.2%, which was calculated based on the closing price per share of the Company’s common stock of ~~$70.96~~$71.69 on ~~March 31,~~September 30, 2018 as shown in the following table:

Liquidity and Capital Resources of the Operating Partnership

In this “Liquidity and Capital Resources of the Operating Partnership” section, the terms “we,” “our,” and “us” refer to the Operating Partnership or the Operating Partnership and the Company together, as the context requires.

General

Our primary liquidity sources and uses are as follows:

Liquidity Sources

Net cash flow from operations;

Borrowings under the Operating Partnership’s unsecured revolving credit facility and term loan facility;

Proceeds from our capital recycling program, including the disposition of less strategic or core 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 enhance our ability to obtain additional sources of liquidity if necessary, and, therefore, we are well-positioned to refinance or repay maturing debt and to pursue our strategy of seeking attractive acquisition opportunities, which we may finance, as necessary, with future public and private issuances of debt and equity securities.

Unsecured Senior Notes - Private Placement

On May 11, 2018, the Operating Partnership entered into a Note Purchase Agreement (the “Note Purchase Agreement”), in connection with the issuance and sale of $50.0 million principal amount of the Operating Partnership’s 4.30% Senior Notes, Series A, due July 18, 2026 (the “Series A Notes”), and $200.0 million principal amount of the Operating Partnership’s 4.35% Senior Notes, Series B, due October 18, 2026 (the “Series B Notes” and, together with the Series A Notes, the “Series A and B Notes”), pursuant to a private placement. The Company drew the full amount of the Series A Notes on July 18, 2018. As of September 30, 2018, there were no amounts issued or outstanding under the Series B Notes. On October 22, 2018, the Company drew the full amount of the Series B Notes, the proceeds of which were used to repay a portion of the outstanding balance on our unsecured revolving credit facility. The Series A and B Notes mature on their respective due dates, 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 April 18 and October 18 of each year beginning April 18, 2019.

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 core 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, infor the remainder of 2018, we could raise approximately $375.0 million of additional capital through our dispositions ~~program ranging from approximately $250 million to $750 million.~~program. However, any potential future disposition 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. In addition, we cannot assure you that we will dispose of any additional properties, or that we will be able to identify and complete the acquisitions of suitable replacement properties to effect Section 1031 Exchanges to defer some or all of the taxable gains related to our capital recycling program.

Forward Equity Offering

On August 8, 2018, the Company entered into forward equity sale agreements with certain financial institutions acting as forward purchasers in connection with an offering of 5,000,000 common shares at an initial gross offering price of $360.5 million, or $72.10 per share, before underwriting discounts, commissions and offering expenses. The forward purchasers borrowed and sold an aggregate of 5,000,000 shares in the offering. The Company did not receive any proceeds from the sale of its common shares by the forward purchasers in the offering. The Company currently expects to fully physically settle the forward sale agreements and receive cash proceeds upon one or more settlement dates, at the Company’s discretion, prior to the final settlement date under the forward sale agreements of August 1, 2019. The forward sale price that we expect to receive upon physical settlement of the agreements will be subject to adjustment for (i) the forward purchasers’ stock borrowing costs and (ii) scheduled dividends during the term of the agreements. The full amount of this offering remains available for future settlement as of the date of this filing.

At-The-Market Stock Offering Program

~~Since commencement of our~~During the nine months ended September 30, 2018, the Company completed its then existing at-the-market stock offering program ~~in December 2014, through March 31, 2018,~~(the “2014 At-The-Market Program”) and commenced a new at-the-market stock offering program (the “2018 At-The-Market Program”) under which we ~~have sold 2,694,242~~may offer and sell shares of our common stock ~~having~~with an aggregate gross sales price of ~~$200.1~~up to $500.0 million. Under the 2018 At-The-Market-Program, the Company may sell shares under forward equity sale agreements (see “Note 6. Stockholders’ Equity of the Company” to our consolidated financial statements included in this report for additional information). During the nine months ended September 30, 2018, under the 2014 At-The-Market Program, we sold 1,369,729 shares of common stock and completed the program. Since commencement of our 2018 At-The-Market Program, as of September 30, 2018, we sold447,466 shares of common stock, none of which were sold under forward equity sale agreements. Approximately $466.2 million ~~and approximately $99.9 million remained~~remains available to be sold under this program. ~~No shares~~

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.

Liquidity Uses

Contractual Obligations

Refer to our 2017 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~~nine months ended ~~March 31,~~September 30, 2018.

Other Liquidity Uses

Development

As of ~~March 31,~~September 30, 2018, we had ~~five~~three development projects under construction. These projects have a total estimated investment of approximately ~~$1.7~~$1.1 billion of which we have incurred approximately ~~$940.0~~$563.8 millionand committed an additional $424.0 millionas of September 30, 2018, of which $323.0 million is expected to be spent through the end of 2019.In addition, as of September 30, 2018, we had two development projects in the tenant improvement phase. These projects have a total estimated investment of approximately $840.0 million of which we have incurred approximately $692.6 million and committed an additional ~~$628 million.The total remaining estimated investment~~$172.0 million as of September 30, 2018, of which $125.0 million is ~~primarily related~~expected to ~~tenant improvements and~~be spent through the ~~timing~~end of ~~when we incur such costs will depend upon leasing activity.~~2019. Furthermore, we currently believe we may spend up to ~~an additional $100 - $300~~$50.0 million on potential future development pipeline projects that we expect we may commence construction on throughout the remainder of 2018. 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.~~program, or strategic venture opportunities.

~~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. However, we can provide no assurance that we will have access to the public or private debt or equity markets in the future on favorable terms or at all. Our next debt maturity with a balance of $75.9 million at March 31, 2018 occurs in June 2019.

~~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, the formation of strategic ventures or through the assumption of existing debt. As of ~~March 31,~~September 30, 2018, we had ~~$41.0~~$15.0 million of acquisition deposits that are nonrefundable ~~subject~~related to ~~closing conditions required~~the future acquisition of an operating property with a purchase price of $146.0 million that is currently expected to ~~be met by the seller.~~close in December 2018. 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

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,~~September 30, 2018, 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 and condition of the 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 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.

In May, the Company completed a private placement of $200.0 million of eight-year, 4.35% unsecured senior notes with a delayed draw option. The table above does not reflect any amounts pertaining to these notes since there were no amounts drawn or outstanding as of September 30, 2018. In October, the Company drew the full amount of these notes, the proceeds of which were used to repay a portion of the outstanding balance on our unsecured line of credit. As of ~~March 31, 2018,~~ the ~~covenant performance under the Unsecured Senior Notes Series A and B due 2027 and 2029 (“private placement notes”),~~date of this report, $165.0 million was ~~substantially similar to the Facility; however, the~~outstanding on our unsecured ~~debt ratio under the private placement notes was 3.15x reflecting definitional differences on unencumbered value.

The Operating Partnership was in compliance with all of its debt covenants as of ~~March 31,~~September 30, 2018. 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.

Consolidated Historical Cash Flow Summary

The following summary discussion of our consolidated historical cash flow is based on the consolidated statements of cash flows in Item 1. “Financial Statements” and is not meant to be an all-inclusive discussion of the changes in our cash flow for the periods presented below. Changes in our cash flow include changes in cash and cash equivalents and restricted cash. Our historical cash flow activity for the ~~three~~nine months ended ~~March 31,~~September 30, 2018 as compared to the ~~three~~nine months ended ~~March 31,~~September 30, 2017 is as follows:

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. ~~While our~~Our net cash provided by operating activities increased by $40.7 million, or 14.7%, for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017 primarily as a result of an increase in cash Net Operating Income generated from our Same Store, Acquisition and Stabilized Development ~~and Acquisition Portfolios increased for the three months ended March 31, 2018 compared to the three months ended March 31, 2017 (see~~Portfolios. See additional information under the caption “—Results of Operations”)~~, our net cash provided by operating activities decreased by $2.3 million, or 2.4% due to changes in other assets and liabilities related to the timing of expenditures.~~.

Investing Activities

Our cash flows from investing activities is generally used to fund development and operating property acquisitions, expenditures for development projects, and recurring and nonrecurring capital expenditures for our operating properties, net of proceeds received from dispositions of real estate assets. Our net cash used in investing activities increased by ~~$161.3~~$624.7 million or

The Company did not ~~acquire~~have any ~~operating properties~~disposition transactions during the ~~three~~nine months ended ~~March 31,~~September 30, 2018 compared to proceeds received from dispositions of $182.5 million during the nine months ended September 30, 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~~During the nine months ended September 30, 2018, we had net cash provided by financing activities ~~decreased $85.7~~of $507.9 million ~~or 38.0%~~compared to net cash used in financing activities of $101.7 million during the nine months ended September 30, 2017, primarily due to ~~lower capital raising activity~~increased borrowings on our unsecured revolving credit facility during the ~~three~~nine months ended ~~March 31,~~September 30, 2018 in order to fund acquisitions and development expenditures.

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 and nine months ended ~~March 31,~~September 30, 2018 and 2017:


	Three Months Ended March 31,						Three Months Ended September 30,						Nine Months Ended September 30,

ITEM 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary market risk we face is interest rate risk. We seek to mitigate this risk by following established risk management policies and procedures. These policies include maintaining prudent amounts of debt, including a greater amount of fixed-rate debt as compared to variable-rate debt in our portfolio, and may include the periodic use of derivative instruments. As of ~~March 31,~~September 30, 2018 and December 31, 2017, we did not have any interest-rate sensitive derivative assets or liabilities. Information about our changes in interest rate risk exposures from December 31, 2017 to ~~March 31,~~September 30, 2018 is incorporated herein by reference from “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations —Liquidity and Capital Resources of the Operating Partnership.”

Market Risk

As of ~~March 31,~~September 30, 2018, approximately ~~7.8%~~16.6% of our total outstanding debt of ~~$2.6~~$2.9 billion (before the effects of debt discounts, premiums and deferred financing costs) was subject to variable interest rates. The remaining ~~92.2%~~83.4% bore interest at fixed rates. All of our interest rate sensitive financial instruments are held for purposes other than trading purposes. In general, interest rate fluctuations applied to our variable-rate debt will impact our future earnings and cash flows. Conversely, interest rate fluctuations applied to our fixed-rate debt will generally not impact our future earnings and cash flows, unless such instruments mature or are otherwise terminated and need to be refinanced. However, interest rate fluctuations will impact the fair value of the fixed-rate debt instruments.

We generally determine the fair value of our secured debt, unsecured revolving credit facility and unsecured term loan facility by performing discounted cash flow analyses using an appropriate market discount rate. We calculate the market rate by obtaining period-end treasury rates for maturities that correspond to the maturities of our fixed-rate debt and then adding an appropriate credit spread based on information obtained from third-party financial institutions. We calculate the market rate of our unsecured revolving credit facility and unsecured term loan facility by obtaining the period-end LIBOR rate and then adding an appropriate credit spread based on information obtained from third-party financial institutions. These credit spreads take into account factors, including but not limited to, our credit profile, the tenure of the debt, amortization period, whether the debt is secured or unsecured, and the loan-to-value ratio of the debt to the collateral. These calculations are significantly affected by the assumptions used, including the discount rate, credit spreads, and estimates of future cash flow. We determine the fair value of each of our publicly traded unsecured senior notes based on their quoted trading price at the end of the reporting period. See Note 11 “Fair Value Measurements and Disclosures” in the consolidated financial statements included in this report for additional information on the fair value of our financial assets and liabilities as of ~~March 31,~~September 30, 2018 and December 31, 2017.

As of ~~March 31,~~September 30, 2018, the total outstanding balance of our variable-rate debt was comprised of borrowings on our unsecured revolving credit facility of ~~$50.0~~$330.0 million and unsecured term loan facility of $150.0 million, which were indexed to LIBOR plus a spread of 1.00% (weighted average interest rate of ~~2.72%~~3.23%) and LIBOR plus a spread of 1.10% (weighted average interest rate of ~~2.90%~~3.23%), respectively. At December 31, 2017, there were no outstanding balances on both our $750.0 million unsecured revolving credit facility and our $150.0 million unsecured term loan facility, but both were available for borrowing at the following variable rates: LIBOR plus a spread of 1.00% (weighted average interest rate of 2.56%) and LIBOR plus a spread of 1.10% (weighted average interest rate of 2.66%), respectively. Assuming no changes in the outstanding balance of our existing variable-rate debt as of ~~March 31,~~September 30, 2018, a 100 basis point increase in the LIBOR rate would increase our projected annual interest expense, before the effect of capitalization, by approximately ~~$2.0~~$4.8 million.

The total carrying value of our fixed-rate debt was approximately $2.4 billion and $2.3 billion as of ~~March 31,~~September 30, 2018 and December 31, ~~2017.~~2017, respectively. The total estimated fair value of our fixed-rate debt was approximately $2.4 billion as of ~~March 31,~~September 30, 2018 and December 31, 2017. For sensitivity purposes, a 100 basis point increase in the discount rate equates to a decrease in the total fair value of our fixed-rate debt of approximately ~~$135.8~~$127.4 million, or ~~5.8%~~5.4%, as of ~~March 31,~~September 30, 2018.Comparatively, a 100 basis point increase in the discount rate equates to a decrease in the total fair value of our fixed-rate debt of approximately $145.0 million, or 6.0%, as of December 31, 2017.
