EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended June 30, 2013 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 June 30, 2013, the Company owned an approximate 97.7% common general partnership interest in the Operating Partnership. The remaining approximate 2.3% common limited partnership interests are owned by non-affiliated investors and certain directors and executive 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, which 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 does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing equity from time to time and guaranteeing certain debt of the Operating Partnership. The Company itself is not directly obligated under any indebtedness, but guarantees some of the debt of the Operating Partnership. The Operating Partnership owns substantially all of the assets of the Company either directly or through its subsidiaries, conducts the operations of the Company's business and is structured as a limited partnership with no publicly traded equity. Except for net proceeds from equity issuances by the Company, which the Company is required to contribute to the Operating Partnership in exchange for partnership units, the Operating Partnership generates the capital required by the Company's business through the Operating Partnership's operations, property dispositions, by the Operating Partnership's incurrence of indebtedness or through the issuance of partnership units.

Noncontrolling interests in the Operating Partnership, 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. This noncontrolling interest represents the Company's 1% indirect general partnership interest in Kilroy Realty Finance Partnership, L.P., which is directly held by Kilroy Realty Finance, Inc., a wholly-owned subsidiary of the Company. The differences between stockholders' equity, partners' capital and noncontrolling interests result from the differences in the equity issued by the Company and the Operating Partnership, and in the Company's noncontrolling interest in Kilroy Realty Finance Partnership, L.P.

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 5, Secured and Unsecured Debt of the Operating Partnership;


◦	Note 6, Noncontrolling Interests on the Company's Consolidated Financial Statements;


◦	Note 7, Stockholders' Equity of the Company;


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


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


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


•	"Item 2: Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources of the Company"; and


•	"Item 2: Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources of the Operating Partnership."

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Three Months Ended June 30, 2013 and 2012

(unaudited)

1. Organization and Basis of Presentation

Organization

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

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

Our stabilized portfolio of operating properties was comprised of the following office properties at June 30, 2013:



	Number of Buildings	Rentable Square Feet	Number of Tenants	Percentage Occupied
Office Properties	115	13,478,791	545	90.7	%

Our stabilized portfolio includes all of our properties with the exception of undeveloped land, development and redevelopment properties currently under construction or committed for construction, "lease-up" properties and properties held-for-sale. We define redevelopment properties as those projects for which we expect to spend significant development and construction costs on existing or acquired buildings pursuant to a formal plan, the intended result of which is a higher economic return on the property. We define "lease-up" properties as properties we recently developed or redeveloped that have not yet reached 95% occupancy and are within one year following cessation of major construction activities. As of June 30, 2013, the following properties were excluded from our stabilized portfolio:



	Number of Properties	Estimated Rentable Square Feet
Development properties under construction ⁽¹⁾	5	1,516,000
Lease-up properties	2	508,000

________________________

(1) Estimated rentable square feet upon completion.

As of June 30, 2013, all of our properties and development and redevelopment projects are owned and all of our business is

currently conducted in the state of California with the exception of eleven office properties located in the state of Washington.

As of June 30, 2013, the Company owned a 97.7% general partnership interest in the Operating Partnership. The remaining 2.3% common limited partnership interest in the Operating Partnership as of June 30, 2013 was owned by non-affiliated investors and certain of our directors and executive officers (see Note 6). Both the general and limited common partnership interests in the Operating Partnership are denominated in common units. The number of common units held by the Company is at all times equivalent to the number of outstanding shares of the Company's common stock, and the rights of all the common units to quarterly distributions and payments in liquidation mirror those of the Company's common stockholders. The common limited partners have certain redemption rights as provided in the Operating Partnership's Seventh Amended and Restated Agreement of Limited Partnership (as amended, the "Partnership Agreement") (see Note 6).

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% general partnership interest in the Finance Partnership. The Operating Partnership owns the remaining 99.0% limited partnership interest. Kilroy Services, LLC ("KSLLC"), which is a wholly-owned subsidiary of the Operating

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Partnership, is the entity through which we conduct substantially all of our development activities. With the exception of the Operating Partnership and Redwood City Partners, LLC (see Note 2), all of our subsidiaries are wholly-owned.

Basis of Presentation

The consolidated financial statements of the Company include the consolidated financial position and results of operations of the Company, the Operating Partnership, the Finance Partnership, KSLLC, Redwood City Partners, LLC and all of our wholly-owned and controlled subsidiaries. The consolidated financial statements of the Operating Partnership include the consolidated financial position and results of operations of the Operating Partnership, the Finance Partnership, KSLLC, Redwood City Partners, LLC and all wholly-owned and controlled subsidiaries of the Operating Partnership. All intercompany balances and transactions have been eliminated in the consolidated financial statements.

The accompanying interim financial statements have been prepared by management in accordance with accounting principles generally accepted in the United States of America ("GAAP") and in conjunction with the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, the interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the accompanying interim financial statements reflect all adjustments of a normal and recurring nature that are considered necessary for a fair presentation of the results for the interim periods presented. However, the results of operations for the interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2013. 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, 2012.

Partially Owned Entities and Variable Interest Entities

Our accounting policy is to consolidate entities in which we have a controlling financial interest and significant decision making control over the entities operations. In determining whether we have a controlling financial interest in a partially owned entity and the requirement to consolidate the accounts of that entity, we consider factors such as ownership interest, board representation, management representation, size of our investment (including loans), authority to control decisions, and contractual and substantive participating rights of the members. In addition to evaluating control rights, we also consolidate entities in which the other member has no substantive kick-out rights to remove the Company as the managing member.

We also evaluate whether the entity is a variable interest entity ("VIE") and whether we are the primary beneficiary. VIEs are entities in which the equity investors do not have sufficient equity at risk to finance their endeavors without additional financial support or that the holders of the equity investment at risk do not have a controlling financial interest. We are deemed to be the primary beneficiary of a VIE when we have the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and the obligation to absorb losses or receive benefits that could potentially be significant to the VIE.

If the requirements for consolidation are not met, the Company would account for investments under the equity method of accounting if we have the ability to exercise significant influence over the entity. Equity method investments would be initially recorded at cost and subsequently adjusted for our share of net income or loss and cash contributions and distributions each period. The Company did not have any equity method investments at June 30, 2013 or December 31, 2012.

As of December 31, 2012 the consolidated financial statements of the Company and the Operating Partnership included two variable interest entities VIEs in which we were deemed to be the primary beneficiary. The VIEs were established during 2012 to facilitate potential like-kind exchanges pursuant to Section 1031 of the Code to defer taxable gains on dispositions for federal and state income tax purposes. During the year ended December 31, 2012, one operating property and one development project were acquired in two separate transactions and transferred to the two special purpose VIEs to facilitate potential Section 1031 Exchanges. The impact of consolidating the VIEs increased the Company's total assets and liabilities by approximately $337.0 million and $111.1 million, respectively, at December 31, 2012. During the three months ended March 31, 2013, the Section 1031 Exchanges were completed and the VIEs were terminated. As a result, $228.3 million of restricted cash set aside at December 31, 2012 to facilitate the Section 1031 Exchanges was released from escrow.

At June 30, 2013, the consolidated financial statements of the Company and the Operating Partnership included one new VIE, Redwood City Partners, LLC, (see Note 2 for further discussion of the formation transaction for this VIE.) The impact of consolidating the VIE increased the Company's total assets, liabilities and noncontrolling interests by approximately $12.0 million, $4.0 million and $4.9 million, respectively, at June 30, 2013.

(5)

In January 2013, in connection with the acquisition of two office buildings in Seattle, Washington, we assumed a mortgage loan that is secured by the project. The assumed mortgage had a principal balance of $83.9 million at the acquisition date and was recorded at fair value on the date of the acquisition resulting in a premium of approximately $11.6 million. The loan requires monthly principal and interest payments based on a 6.4 year amortization period.


(6)	In January 2013, we repaid this loan prior to the stated maturity.

Although our mortgage loans are secured and non-recourse to the Company and the Operating Partnership, the Company

provides limited customary secured debt guarantees for items such as voluntary bankruptcy, fraud, misapplication of payments,

and environmental liabilities.

4.25% Exchangeable Senior Notes

The table below summarizes the balance and significant terms of the Company's 4.25% Exchangeable Notes due November 2014 (the "4.25% Exchangeable Notes") outstanding as of June 30, 2013 and December 31, 2012.

(2)	The rate at which we record interest expense for financial reporting purposes, which reflects the amortization of the discounts on the 4.25% Exchangeable Notes. This rate represents our conventional debt borrowing rate at the date of issuance.


(3)	The exchange rate, exchange price, and the number of shares to be delivered upon conversion are subject to adjustment under certain circumstances including increases in our common dividends.

The 4.25% Exchangeable Notes are exchangeable for shares of the Company's common stock prior to maturity only upon the occurrence of certain events. During the three and six months ended June 30, 2013, the closing sale price per share of the common stock of the Company was more than 130% of the exchange price per share of the Company’s common stock for at least 20 trading days in the specified period. As a result, for the three-month period ending September 30, 2013, the 4.25% Exchangeable Notes are exchangeable at the exchange rate stated above and may be exchangeable thereafter, if one or more of the events were again to occur during future measurement periods.

For the three and six months ended June 30, 2013 and 2012, the per share average trading price of the Company's common stock on the NYSE was higher than the $35.93 exchange price for the 4.25% Exchangeable Notes, as presented below:



	Three Months Ended June 30,		Six Months Ended June 30,
	2013	2012	2013	2012
Per share average trading price of the Company's common stock	$54.49	$46.75	$52.86	$44.82

The 4.25% Exchangeable Notes were convertible as of June 30, 2013, and were not convertible as of June 30, 2012. If the Exchangeable Notes were convertible for all periods presented, the approximate fair value of the shares upon conversion at June 30, 2013 and 2012, using the per share average trading price presented in the table above, would have been as follows:



	Three Months Ended June 30,				Six Months Ended June 30,
	2013		2012		2013		2012
	(in thousands)
Approximate fair value of shares upon conversion	$	259,200	$	226,300	$	254,000	$	218,600

Approximate fair value in excess amount of principal amount	$	86,700	$	53,800	$	81,500	$	46,100

See Notes 12 and 13 for a discussion of the impact of the 4.25% Exchangeable Notes on our diluted earnings per share and unit calculations for the periods presented.

Interest Expense for the Exchangeable Notes

The unamortized discount on the 4.25% Exchangeable Notes and the 3.25% Exchangeable Notes due April 2012 (the "3.25% Exchangeable Notes" and together with the 4.25% Exchangeable Notes, the "Exchangeable Notes") is accreted as additional interest expense from the date of issuance through the maturity date of the applicable Exchangeable Notes. The following table summarizes the total interest expense attributable to the 4.25% Exchangeable Notes and attributable to the 3.25% Exchangeable Notes (which were repaid upon maturity in April 2012), in each case based on the respective effective interest rates, before the effect of capitalized interest, for the three and six months ended June 30, 2013 and 2012:

Interest expense attributable to the Exchangeable Notes	$	2,930	$	3,175	$	5,841	$	8,007

________________________


(1)	The Company repaid the 3.25% Exchangeable Notes in April 2012. Interest payments and discount amortization for the three and six months ended June 30, 2013 are solely attributable to the 4.25% Exchangeable Notes.

Capped Call Transactions

In connection with the offering of the 4.25% Exchangeable Notes, we entered into capped call option transactions ("capped calls") to mitigate the dilutive impact of the potential conversion of the 4.25% Exchangeable Notes. The table below summarizes our capped call option positions for the 4.25% Exchangeable Notes as of both June 30, 2013 and December 31, 2012.

Unsecured Senior Notes

In January 2013, the Operating Partnership issued unsecured senior notes in a public offering with an aggregate principal balance of $300.0 million, which is included in unsecured debt, net on our consolidated balance sheets. The unsecured senior notes, which are scheduled to mature on January 15, 2023, require semi-annual interest payments each January and July based on a stated annual interest rate of 3.80%. The unsecured senior notes are shown net of the initial issuance discount of $0.1 million on the consolidated balance sheets. The Company used a portion of the net proceeds for general corporate purposes, including the repayment of borrowings under the Operating Partnership's revolving credit facility.

Unsecured Revolving Credit Facility

The following table summarizes the balance and terms of our revolving credit facility as of June 30, 2013 and December 31, 2012, respectively:

(1)	We may elect to borrow, subject to bank approval, up to an additional $200.0 million under an accordion feature under the terms of the revolving credit facility.


(2)	The revolving credit facility interest rate was calculated based on an annual rate of LIBOR plus 1.450% as of both June 30, 2013 and December 31, 2012. No interest rate is shown as of June 30, 2013 because no borrowings were outstanding.


(3)	The facility fee is paid on a quarterly basis and is calculated based on the total borrowing capacity. In addition to the facility fee, from 2010 to 2012 we incurred debt origination and legal costs totaling approximately $10.2 million that are currently being amortized through the maturity date of the revolving credit facility.


(4)	Under the terms of the revolving credit facility, we may exercise an option to extend the maturity date by one year.

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

Debt Covenants and Restrictions

The revolving credit facility, the term loan facility, the unsecured senior notes, and certain other secured debt arrangements contain covenants and restrictions requiring us to meet certain financial ratios and reporting requirements. Some of the more restrictive financial covenants include a maximum ratio of total debt to total asset value, a minimum fixed-charge coverage ratio, a minimum unsecured debt ratio, and a minimum unencumbered asset pool debt service coverage ratio. Noncompliance with one or more of the covenants and restrictions could result in the full or partial principal balance of the associated debt becoming immediately due and payable. We believe we were in compliance with all of our debt covenants as of June 30, 2013.

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

Common Units of the Operating Partnership

The Company owned a 97.7%, 97.6% and 97.6% common general partnership interest in the Operating Partnership as of June 30, 2013, December 31, 2012, and June 30, 2012, respectively. The remaining 2.3%, 2.4% and 2.4% common limited partnership interest as of June 30, 2013, December 31, 2012 and June 30, 2012, respectively, was owned by non-affiliate investors and certain of our executive officers and directors in the form of noncontrolling common units. There were 1,821,503, 1,826,503 and 1,718,131 common units outstanding held by these investors, executive officers and directors as of June 30, 2013, December 31, 2012 and June 30, 2012, respectively.

The noncontrolling common units may be redeemed by unitholders for cash. We, at our option, may satisfy the cash redemption obligation with shares of the Company's common stock on a one-for-one basis. Whether satisfied in cash or shares of the Company's common stock, 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 $94.5 million and $85.4 million as of June 30, 2013 and December 31, 2012, 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.

Noncontrolling Interest in Consolidated Subsidiary

The noncontrolling interest in consolidated subsidiary represents the third party equity interest in Redwood City Partners, LLC (see Note 2). This noncontrolling interest was $4.9 million at June 30, 2013.

8. Partners' Capital of the Operating Partnership

Issuance of Common Units

During the three and six months ended June 30, 2013, the Company utilized its at-the-market stock offering program to issue 360,729 and 814,408 shares of common stock, respectively, as discussed in Note 7. The net offering proceeds for the three and six months ended June 30, 2013 of approximately $19.4 million and $42.8 million, respectively, were contributed by the Company to the Operating Partnership in exchange for 360,729 and 814,408 common units, respectively.

Common Units Outstanding

The Company owned 75,710,907, 74,926,981, and 68,927,731 common units representing a 97.7%, 97.6%, and 97.6% common general partnership interest in the Operating Partnership as of June 30, 2013, December 31, 2012, and June 30, 2012, respectively. The remaining 2.3%, 2.4%, and 2.4% common limited partnership interest as of June 30, 2013, December 31, 2012, and June 30, 2012, respectively, was owned by certain of our executive officers and directors and non-affiliate investors in the form of noncontrolling common units. There were 1,821,503, 1,826,503, and 1,718,131 common units outstanding held by these investors, officers and directors as of June 30, 2013, December 31, 2012, and June 30, 2012, respectively. For a further discussion of the noncontrolling common units as of June 30, 2013 and December 31, 2012, refer to Note 6.

9. Share-Based Compensation

Stockholder Approved Equity Compensation Plans

As of June 30, 2013, we maintained one share-based incentive compensation plan, the Kilroy Realty 2006 Incentive Award Plan as amended (the "2006 Plan"). As of June 30, 2013, 47,994 shares were available for grant under the 2006 Plan. The number of shares that remains available for grant is calculated using the weighted share counting provisions set forth in the 2006 Plan, which are based on the type of awards that are granted. The maximum number of shares available for grant subject to full value awards (which generally include equity awards other than options and stock appreciation rights) was 16,436 shares as of June 30, 2013.

On April 4, 2013, the Executive Compensation Committee of the Company's Board of Directors granted 19,084 RSUs to the Company's Chief Operating Officer as part of his modified employment agreement. Fifty-percent of the RSUs granted are scheduled to vest in six equal annual installments beginning on December 31, 2013 through December 31, 2018. The grant date fair value of these time-based RSUs was $0.5 million, which was based on the $53.05 closing share price of the Company's common stock on the New York Stock Exchange on the grant date. Compensation expense will be recognized on a straight-line basis over the service vesting period for these time-based RSUs. The remaining 50% of the RSUs granted are scheduled to vest in six equal annual installments for each calendar year during 2013 through 2018 based on the achievement of certain absolute or relative total shareholder return goals measured annually or, if neither of the shareholder return hurdles are achieved for an applicable year during the performance period, those RSUs will remain eligible to vest in a subsequent year (ending in 2018) based on the achievement of a cumulative total shareholder return goal. The grant date fair value of these market measure-based RSUs was $0.4 million and was calculated using a Monte Carlo simulation pricing model based on the assumptions in the table below. The grant date fair value is allocated among each of the six annual vesting tranches for these market measure-based RSUs and compensation expense will be recognized over the service vesting period using the accelerated expense attribution method.

The computation of expected volatility is based on a blend of the historical volatility of our shares of common stock over 12 years as that is expected to be most consistent with future volatility and equates to a time period twice as long as the six-year term 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 the grant date. The expected dividend yield is estimated by examining the average of the historical dividend yield levels over the six-year term of the RSUs and our current annualized dividend yield as of the grant date. The expected life of the RSUs is equal to the six year vesting period.



	April 2013 Market Measure-based RSU Grant
Grant date fair value per share	$44.55
Expected share price volatility	27.00%
Risk-free interest rate	0.90%
Dividend yield	3.60%
Expected life	6 years

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

On April 4, 2013, the terms of 61,327 time-based RSUs granted to certain officers of the Company in January 2013 were modified to include market and performance-based vesting requirements based on certain total shareholder return and FFO per share targets. The RSUs will vest in five equal annual installments over the five-years requisite service period based on the achievement of certain absolute or relative total shareholder return goals measured annually or, if neither of the shareholder return hurdles are achieved for an applicable year during the performance period, those RSUs will remain eligible to vest in a subsequent year (ending in 2018) based on the achievement of a cumulative total shareholder return goal, as well as (in each case) continued employment through the applicable vesting date. The Company's closing stock price on the date of modification was $53.05. The compensation expense related to the modified RSUs will be recognized using the accelerated attribution expense method through the remainder of the five-year requisite service period.

On March 30, 2012, the Executive Compensation Committee of the Company's Board of Directors granted 103,239 RSUs to the Company's Chief Executive Officer. The RSUs granted vest in seven equal annual installments for each calendar year during 2012 through 2018 based on the achievement of certain absolute or relative total shareholder return goals measured annually or, if neither of the shareholder return hurdles are achieved for an applicable year during the performance period, those RSUs will remain eligible to vest in a subsequent year (ending in 2018) based on the achievement of a cumulative total shareholder return goal, as well as (in each case) continued employment through the applicable vesting date.

10. Commitments and Contingencies

General

As of June 30, 2013, we had commitments of approximately $514.1 million for contracts and executed leases directly related to our operating and redevelopment properties. This amount includes the $27.5 million that we expect to pay before the end of 2013 upon the closing of the purchase of the land underlying the ground lease at 360 Third Street in San Francisco, CA. We exercised an option to acquire the land during the fourth quarter of 2012.

Environmental Matters

We follow the policy of monitoring our properties for the presence of hazardous or toxic substances. While there can be no assurance that a material environmental liability does not exist, we are not currently aware of any environmental liability with respect to the properties that would have a material adverse effect on our financial condition, results of operations, and cash flow. Further, we are not aware of any environmental liability or any unasserted claim or assessment with respect to an environmental liability that we believe would require additional disclosure or the recording of a loss contingency.

Property Damage Settlement

During the three months ended June 30, 2013, we settled an outstanding matter related to property damage at one of our properties. In connection with this settlement, we received a final cash payment of $5.2 million and recognized this amount in other property income during the three months ended June 30, 2013.

11. Fair Value Measurements and Disclosures

Overview and Background

We are a self-administered REIT active in office submarkets along the West Coast. We own, develop, acquire and manage real estate assets, consisting primarily of Class A properties in the coastal regions of Los Angeles, Orange County, San Diego County, the San Francisco Bay Area and greater Seattle, which we believe have strategic advantages and strong barriers to entry. We own our interests in all of our properties through the Operating Partnership and the Finance Partnership and conduct substantially all of our operations through the Operating Partnership. We owned a 97.7%, 97.6% and 97.6% general partnership interest in the Operating Partnership as of June 30, 2013, December 31, 2012 and June 30, 2012, respectively. All our properties are held in fee except for the 11 office buildings that are held subject to long−term ground leases for the land.

Factors That May Influence Future Results of Operations

Acquisitions. During the six months ended June 30, 2013, we acquired two office buildings in one transaction for approximately $170.0 million (see Note 2 to our consolidated financial statements included in this report for more information). During 2012, we acquired 14 office buildings in seven transactions with an aggregate purchase price of approximately $674.0 million and six development and redevelopment opportunity projects in six transactions with an aggregate purchase price of approximately $340.3 million. We generally finance our acquisitions through proceeds from the issuance of debt and equity securities, borrowings under our revolving credit facility, proceeds from our capital recycling program and the assumption of existing debt.

As a key component of our growth strategy, we continually evaluate acquisition opportunities (including undeveloped land, development and redevelopment opportunities and office properties) as they arise. As a result, at any point in time we may have one or more potential acquisitions under consideration that are in varying stages of evaluation, negotiation or due diligence review, which may include potential acquisitions under contract. As of the date of the filing of this report, we were in negotiations to acquire an additional operating property. We cannot provide assurance that we will acquire this property. In the future, we may enter into agreements to acquire other properties, either as wholly-owned properties or through joint ventures, and those agreements typically will be subject to the satisfaction of closing conditions. We cannot provide assurance that we will enter into any agreements to acquire properties or that the potential acquisitions contemplated by any agreements we may enter into in the future will be completed. Costs associated with acquisitions accounted for as business combinations are expensed as incurred, and we may be unable to complete an acquisition after making a nonrefundable deposit or incurring acquisition−related costs. In addition, acquisitions are subject to various other risks and uncertainties. During the three and six months ended June 30, 2013, we expensed approximately $0.2 million and $0.8 million, respectively, of third-party acquisition costs, and we anticipate that we will incur additional third-party acquisition costs throughout 2013 as we pursue other potential acquisitions. We expect that we will have increased our focus on the acquisition of undeveloped land and development and redevelopment opportunities during 2013.

Undeveloped Land / Formation of New Consolidated Subsidiary. On June 27, 2013, the Company entered into an agreement with an unaffiliated third party and formed a new consolidated subsidiary, Redwood City Partners, LLC. In connection with this formation transaction, the Company acquired a 0.35 acre land site, completing the first phase of the land assemblage for its plans to develop an approximate 300,000 square foot office project in Redwood City, California. (See Note 2 to our consolidated financial statements included in this report for more information).

Capital Recycling Program. As part of our current and ongoing strategy, we continuously evaluate opportunities for the potential disposition of properties and undeveloped land in our portfolio with the intent of recycling the proceeds generated from the disposition of non-strategic properties into capital to fund new operating and development acquisitions, development and redevelopment expenditures, to repay long-term debt and for other general corporate purposes. As part of our capital recycling strategy, we intend, when practical, to enter into Section 1031 Exchanges to defer some or all of the taxable gains, if any, on the sales for federal and state income tax purposes.

In connection with this strategy, during the three months ended June 30, 2013, we completed the sale of one office building located in Calabasas, CA for a gross sales price of approximately $14.7 million (see Note 2 to our consolidated financial statements included in this report for more information). In addition, we anticipate that we could dispose of approximately $150 million - $300 million of additional operating properties and/or undeveloped land during the next 12 -18 months in connection with our capital recycling program.

The timing of any potential future disposition transactions will depend on market conditions and other factors, including but not limited to our capital needs and our ability to defer some or all of the taxable gains on the sales. We cannot assure that we will dispose of any additional properties or that future acquisitions and/or dispositions, if any, will qualify as Section 1031 Exchanges.

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 six months ended June 30, 2013.

_______________________


(1)	First generation leasing includes space where we have made capital expenditures that result in additional revenue generated when the space is re-leased. Second generation leasing includes space where we have made capital expenditures to maintain the current market revenue stream.


(2)	Represents leasing activity for leases that commenced or signed during the period, including first and second generation space, net of month-to-month leases. Excludes leasing on new construction.


(3)	Amounts exclude tenant-funded tenant improvements.


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


(5)	Excludes commenced and executed leases of approximately 144,000 and 133,000 rentable square feet, respectively, for the six months ended June 30, 2013, for which the

space was vacant longer than one year or being leased for the first time. Space vacant for more than one year is excluded from our change in rents calculations to provide a

meaningful market comparison.


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


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


(8)	For the three months ended June 30, 2013, 16 leases totaling approximately 107,000 rentable square feet were signed but had not commenced as of June 30, 2013. For the six months ended June 30, 2013, 21 leases totaling approximately 267,000 rentable square feet were signed but had not commenced as of June 30, 2013.

As of June 30, 2013, we believe that the weighted average cash rental rates for our stabilized portfolio, including recently acquired operating properties are approximately at the current average market rental rates, although individual properties within any particular submarket presently may be leased either above, below, or at the current market rates within that submarket, and the average rental rates for individual submarkets may be above, below, or at the average cash rental rate of our portfolio.

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

Scheduled Lease Expirations. The following table sets forth certain information regarding our lease expirations for our stabilized portfolio for the remainder of 2013 and the next five years.

________________________

(1)

The information presented for all lease expiration activity reflects leasing activity through June 30, 2013 for our stabilized portfolio. For leases that have been renewed early or space that has been re-leased to a new tenant, the expiration date and annualized base rent information presented takes into consideration the renewed or re-leased lease terms. Excludes space leased under month-to-month leases, intercompany leases, vacant space, and lease renewal options not executed as of June 30, 2013.


(2)	Annualized base rent includes the impact of straight-lining rent escalations and the amortization of free rent periods and excludes the impact of the following: amortization of

deferred revenue related tenant-funded tenant improvements, amortization of above/below market rents, amortization for lease incentives due under existing leases, and

expense reimbursement revenue. Additionally, the underlying leases contain various expense structures including full service gross, modified gross and triple net. Percentages

represent percentage of total portfolio annualized contractual base rental revenue. For additional information on tenant improvement and leasing commission costs incurred by

the Company for the current reporting period, please see further discussion under the caption "Information on Leases Commenced and Executed."

In addition to the 1.3 million rentable square feet, or 9.3%, of currently available space in our stabilized portfolio, leases representing approximately 2.6% and 10.4% of the occupied square footage of our stabilized portfolio are scheduled to expire during the remainder of 2013 and in 2014, respectively. The leases scheduled to expire during the remainder of 2013 and in 2014 represent approximately 1.5 million rentable square feet of office space or 11.0% of our total annualized base rental revenue. We believe that the weighted average cash rental rates are slightly under the current average quoted market rates for leases scheduled to expire during the remainder of 2013 and 2014, although individual properties within any particular submarket presently may be leased either above, below, or at the current quoted market rates within that submarket, and the average rental rates for individual submarkets may be above, below, or at the average cash rental rate of our overall portfolio. Our ability to re-lease available space depends upon both general market conditions and the market conditions in the specific regions in which individual properties are located.

Redevelopment Projects

We believe that a portion of our potential long-term future growth will continue to come from redevelopment opportunities both through acquired properties and within our existing portfolio. Redevelopment opportunities are those projects in which we spend significant development and construction costs on existing or acquired buildings pursuant to a formal plan, the intended result of which is a higher economic return on the property. As of June 30, 2013, we had two redevelopment projects in lease-up.

•

3880 Airport Way, Long Beach, submarket of Los Angeles, on which we commenced redevelopment in the third quarter of 2011. This lease-up property, encompassing approximately 98,000 rentable square feet, was 50% leased prior to the commencement of redevelopment which was done in two phases. Redevelopment on the first half, which was leased, was completed during the second quarter of 2012, and redevelopment on the second half was completed in the fourth quarter of 2012. The lease-up project will have a total estimated investment of approximately $19.9 million upon completion, including the $6.3 million net carrying value of the project at the commencement of redevelopment.

•

360 Third Street, South of Market Area, submarket of San Francisco, on which we commenced redevelopment in the fourth quarter of 2011. Redevelopment for this project was completed in the first quarter of 2013. The lease-up project, which encompasses approximately 410,000 rentable square feet, will have a total estimated investment of approximately $185.0 million at completion, including the $88.5 million net carrying value of the project at the commencement of redevelopment plus $27.5 million that we expect to pay in 2013 to acquire the land that is currently subject to a ground lease. As of June 30, 2013, the project is 85% leased and 55% occupied.

In-Process and Future Development Pipeline

We believe that a portion of our long-term future growth will also come from the completion of our under construction and in-process projects as well as executing on our future development pipeline, subject to market conditions. During 2012, we increased our focus on value-add and highly accretive development opportunities and expanded our future development pipeline through targeted acquisitions of development opportunities on the West Coast.

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

As of the date of this report, our near-term development pipeline consisted of the following five projects under construction and the projects that we may commence construction on in the second half of 2013.

•

690 E. Middlefield Road, Mountain View, California, which we acquired in May 2012. We acquired the project for $84.0 million, comprised of a cash purchase price of $74.5 million plus $9.5 million of assumed leasing commissions and other net accrued liabilities. The development project, which is 100% pre-leased to Synopsys, Inc., has a total estimated investment of approximately $196.9 million and is expected to encompass approximately 341,000 rentable square feet upon completion. Construction is currently in process and is expected to be completed in the first quarter of 2015.

•

331 Fairchild Drive, Mountain View, California, which we acquired in December 2012 and is 100% pre-leased. We acquired the project for $18.9 million plus $2.9 million of development costs reimbursed to the seller and are developing an approximately 88,000 square foot building for Audience, Inc. The development project has a total estimated investment of approximately $45.1 million. Construction is currently in process and is expected to be completed in the fourth quarter of 2013.

•

350 Mission Street, South of Market Financial District, San Francisco, California, which we acquired in October 2012. Shortly after acquisition, we pre-leased the entire project to salesforce.com, inc. and are currently planning to develop an approximately 400,000 square foot, 27 story office tower that adapts our open-plan workspace concepts to a high-rise office environment. The property is expected to be LEED platinum certified and the first ground up development property in the city expected to receive this designation. The development project has a total estimated investment of approximately $254.7 million. We are currently pursuing entitlements to increase this project to a 30-story office tower, which would increase the estimated rentable square feet and total estimated investment. Construction is currently in process and is expected to be completed in the first quarter of 2015.

•

555-599 N. Mathilda Avenue, Sunnyvale, California, which we acquired in December 2012. The project, which is comprised of one operating property and a future development site, is 100% pre-leased. Our plan at this project is to continue operating the existing building and develop an approximately 587,000 square foot office complex for LinkedIn, Inc., the tenant in the current existing building. The development project has a total estimated investment of approximately $312.9 million. Construction is currently in process and is expected to be completed in the third quarter of 2014.

•

Columbia Square, in Hollywood, California, which we acquired in September 2012. This project is a historical media campus located in the heart of Hollywood, two blocks from the corner of Sunset Boulevard and Vine Street. The site is fully entitled for the development of an 875,000 rentable square foot office, retail and multi-family mixed use project under a 15-year development agreement that includes three existing buildings. During the second quarter we commenced redevelopment of the three existing historical buildings, which encompass approximately 100,000 rentable square feet. Additionally, we are planning to develop approximately 575,000 square feet of office, retail and residential space in multiple phases. We currently expect to invest an additional $306.5 - $316.5 million for a total estimated investment of approximately $380 - $390 million. Our plan is to create a mixed-use campus that preserves the historical character while establishing a new center for entertainment and media companies.

•

333 Brannan Street, South of Market Area, San Francisco, California, which we acquired in July 2012. We continue to make good progress on the entitlements for this project and could be ready to begin construction in the fourth quarter of 2013. We currently expect to develop an approximately 170,000 rentable square foot office building on this site that will include all the features, amenities and systems that tech and media tenants need. We currently expect to invest an additional $74.1 - $79.1 million for a total estimated investment of approximately $95 - $100 million.


•	Redwood Towers, in Redwood City, California. In June 2013 we entered into an agreement with a local partner and acquired a 0.35 acre land site, completing the first phase of the land assemblage for our plans to develop an approximate 300,000 square foot office project. We currently expect a total estimated investment for the project of $175 - $180 million.

In the future, we may also enter into agreements to acquire other development or redevelopment opportunities, either as wholly-owned properties or through joint ventures and those agreements typically will be subject to the satisfaction of closing conditions. In addition, as of June 30, 2013, we had additional undeveloped land holdings, located primarily in various submarkets in San Diego County with an aggregate cost basis of approximately $291.0 million.

This increase in our development and redevelopment activities will continue to cause an increase in the average development asset balances qualifying for interest and other carry cost capitalization in future periods. During the three and six months ended June 30, 2013, we capitalized interest on in process development projects, redevelopment projects in lease-up, and development pipeline projects with an aggregate cost basis balance of approximately $795.8 million at June 30, 2013, as it was determined these projects qualified for interest and other carry cost capitalization under GAAP. For the three and six months ended June 30, 2013, we capitalized $8.5 million and $16.2 million, respectively, of interest to our qualifying redevelopment and development projects. For the three and six months ended June 30, 2012, we capitalized $4.3 million and $8.2 million, respectively, of interest to our qualifying redevelopment and development projects. For the three and six months ended June 30, 2013, we capitalized $2.0 million and $3.4 million, respectively, of internal costs to our qualifying redevelopment and development projects. For the three and six months ended June 30, 2012, we capitalized $0.6 million and $1.4 million, respectively, of internal costs to our qualifying redevelopment and development projects.

Incentive Compensation. Our Executive Compensation Committee determines compensation, including equity and cash incentive programs, for our executive officers in accordance with the terms and conditions of applicable agreements and incentive award programs. For 2013 the annual cash bonus program is structured to allow the Executive Compensation Committee to evaluate a variety of key quantitative and qualitative factors at the end of the year and make a determination of incentive compensation for executive officers based on the Company's and management's overall performance. We expect that any future equity incentive awards to executives will be subject to a time-based vesting schedule with a portion of the awards subject to both time-based vesting and performance-based vesting requirements. As a result, accrued incentive compensation and compensation expense for future incentive compensation awards may be affected by our operating and development performance, financial results, total shareholder return, market conditions or other performance conditions. Consequently, we cannot predict the amounts that will be recorded in future periods related to such incentive compensation.

Share-Based Compensation. As of June 30, 2013, there was $30.4 million of total unrecognized compensation cost related to outstanding nonvested shares of restricted common stock, RSUs and stock options issued under share-based compensation arrangements. Those costs are expected to be recognized over a weighted-average period of 2.5 years. The $30.4 million of unrecognized compensation cost does not reflect the future compensation cost for any potential share-based awards that may be issued. Share-based compensation expense for potential future awards could be affected by our operating and development performance, financial results, total shareholder return and market conditions. Consequently, we cannot predict the amounts that will be recorded in future periods for such share-based awards. See Note 9 to our consolidated financial statements for additional information regarding our share-based incentive compensation plan.

Stabilized Portfolio Information

As of June 30, 2013, our stabilized portfolio was comprised of 115 office properties encompassing an aggregate of approximately 13.5 million rentable square feet. Our stabilized portfolio includes all of our properties with the exception of undeveloped land, development and redevelopment properties currently under construction or committed for construction, “lease-up” properties and properties held-for-sale. We define lease-up properties as properties recently developed or redeveloped that have not yet reached 95% occupancy and are within one year following cessation of major construction activities. We define redevelopment properties as those projects for which we expect to spend significant development and construction costs on existing or acquired buildings pursuant to a formal plan, the intended result of which is a higher economic return on the property. Our stabilized portfolio also excludes our future development pipeline, which is comprised of ten potential development sites, representing 119.6 gross acres of undeveloped land.

At June 30, 2013, our stabilized portfolio excluded two "lease-up" properties and five development properties currently under construction.

Current Regional Information

We have generally seen rental rates stabilize and start to improve in many of our submarkets. We have also seen vacancy rates in many of our submarkets are starting to decrease.

Los Angeles and Ventura Counties. Our Los Angeles and Ventura Counties stabilized portfolio of 3.4 million rentable square feet was 91.9% occupied with approximately 275,000 available rentable square feet as of June 30, 2013 compared to 94.0% occupied with approximately 210,100 available rentable square feet as of December 31, 2012. The decrease in occupancy is primarily attributable to the expiration of three leases. As of June 30, 2013, we have leased approximately 15,000 rentable square feet in this region that was vacant at June 30, 2013 to five tenants. The new leases are scheduled to commence at various times throughout the remainder of 2013.

As of June 30, 2013, leases representing an aggregate of approximately 66,600 and 384,700 rentable square feet are scheduled to expire during the remainder of 2013 and in 2014, respectively, in this region. The aggregate rentable square feet under the leases scheduled to expire in this region during the remainder of 2013 and in 2014 represents approximately 3.8% of our occupied rentable square feet and 3.7% of our annualized base rental revenues in our total stabilized portfolio as of June 30, 2013.

The decrease in occupancy is primarily attributable to the expiration of five leases.

As of June 30, 2013, leases representing an aggregate of approximately 24,800 and 57,200 rentable square feet are scheduled to expire during the remainder of 2013 and in 2014, respectively, in this region. The aggregate rentable square feet under leases scheduled to expire in 2013 and 2014 represents approximately 0.7% of our occupied rentable square feet and 0.6% of our annualized base rental revenues in our total stabilized portfolio as of June 30, 2013.

Results of Operations

Net Operating Income

Management internally evaluates the operating performance and financial results of our stabilized portfolio based on Net Operating Income. We define “Net Operating Income” as operating revenues (rental income, tenant reimbursements, and other property income) less operating expenses (property expenses, real estate taxes, provision for bad debts, and ground leases).

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

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


•	Same Store Properties - which includes the results of all of the office properties that were owned and included in our stabilized portfolio as of January 1, 2012 and still owned and included in the stabilized portfolio as of June 30, 2013;


•	Acquisition Properties - which includes the results, from the dates of acquisition through the periods presented, for the fourteen office buildings we acquired during 2012 and the two office buildings we acquired during the six months ended June 30, 2013;


•	Stabilized Redevelopment Properties - which includes the results generated by two office buildings that were moved into the stabilized portfolio upon completion of redevelopment in the fourth quarter of 2012; and


•	Other Properties - which includes the results of properties not included in our stabilized portfolio. These properties consist of two office buildings in "lease-up" and one office building that was moved from the stabilized portfolio during 2012 to development because the property is being repositioned.

The following table sets forth certain information regarding the property groups within our stabilized portfolio as of June 30, 2013:

Acquisition Properties	16	2,080,001

Net Operating Income increased $20.0 million, or 29.2%, for the three months ended June 30, 2013 as compared to the three months ended June 30, 2012 primarily resulting from:


•	An increase of $10.8 million attributable to the Acquisition Properties;


•	An increase of $4.4 million attributable to the Same Store Properties primarily resulting from:


•	An increase in other property income of $5.3 million primarily due to a receipt of a settlement payment related to property damage at one of our properties. Other property income for both periods consist primarily of lease termination fees and other miscellaneous income;


•	A partially offsetting increase in property and related expenses of $1.1 million primarily resulting from:


•	An increase of $0.8 million in property expenses primarily as a result of:


◦	an increase in certain recurring operating costs of approximately $1.3 million primarily related to property management expenses, insurance, other service-related costs and $0.2 million of non-recurring legal fees; partially offset by


◦	a receipt of approximately $0.4 million in insurance proceeds during the three months ended June 30, 2013, which were recorded as reduction of property expenses because the charge for the related property damage was recorded as property expenses in prior periods; and


◦	a reduction of repairs and maintenance expense of $0.3 million related to non-recurring expenses incurred in the three months ended June 30, 2012;


•	An increase in real estate taxes of $0.3 million primarily as a result of higher taxes at several properties and property tax refunds received in in 2012 that related to prior periods; and


•	Rental income remained flat due to additional revenue resulting from an increase in tenant renewals and new leases at higher rental rates, offset by a decrease in average occupancy of 1.7%, from 91.5% for the three months ended June 30, 2012, to 89.8% for the three months ended June 30, 2013;


•	An increase in tenant reimbursements of $0.4 million primarily resulting from an increase in reimbursable property expenses and real estate taxes;


•	An increase of $2.9 million attributable to the Stabilized Redevelopment Properties; and


•	An increase of $1.8 million attributable to the Other Properties primarily resulting from income generated in 2013 from:


•	one redevelopment property in lease-up that was 50% occupied at June 30, 2013. The tenant took occupancy of this space in June 2012; and


•	one redevelopment property in lease-up that was 55% occupied at June 30, 2013. The tenant took occupancy of this space in July 2012.

Other Expenses and Income

General and Administrative Expenses

General and administrative expenses increased $0.6 million, or 6.5%, for the three months ended June 30, 2013 compared to the three months ended June 30, 2012 primarily attributable to an increase in payroll and administrative costs associated with the growth of the Company and higher payroll costs associated with the renegotiation of our Chief Operating Officer's employment agreement in April 2013.

Depreciation and Amortization

Depreciation and amortization increased by $11.2 million, or 29.5%, for the three months ended June 30, 2013 compared to the three months ended June 30, 2012, primarily related to the Acquisition Properties.

Interest Expense

The following table sets forth our gross interest expense, including debt discounts/premiums and loan cost amortization, net of capitalized interest, including capitalized debt discounts/premiums and loan cost amortization for the three months ended June 30, 2013 and 2012:



	Three Months Ended June 30,
	2013			2012			Dollar Change			Percentage Change
	($ in thousands)
Gross interest expense	$	27,914		$	23,489		$	4,425		18.8	%
Capitalized interest	(8,480		)	(4,334		)	(4,146		)	95.7	%
Interest expense	$	19,434		$	19,155		$	279		1.5	%

Gross interest expense, before the effect of capitalized interest, increased $4.4 million, or 18.8%, for the three months ended June 30, 2013 compared to the three months ended June 30, 2012 resulting from an increase in our average outstanding debt balances partially offset by a decrease in our weighted average GAAP effective interest rate, which includes the impact of debt discounts and premiums, from approximately 5.5% during the three months ended June 30, 2012 to approximately 4.8% during the three months ended June 30, 2013.

Capitalized interest increased $4.1 million, or 95.7%, for the three months ended June 30, 2013 compared to the three months ended June 30, 2012 primarily attributable to an increase in our development and redevelopment activity, which resulted in higher average asset balances qualifying for interest capitalization.

•	An increase of $24.6 million attributable to the Acquisition Properties;


•	An increase of $1.8 million attributable to the Same Store Properties primarily resulting from:

•

An increase in other property income of $4.5 million primarily due to the receipt of a $5.2 million property damage settlement payment at one of our properties offset by a $0.7 million property damage settlement payment received for the six months ended June 30, 2012 for two of our properties. Other property income for both periods consist primarily of lease termination fees and other miscellaneous income;


•	A partially offsetting increase in property and related expenses of $4.9 million primarily resulting from:


•	An increase of $3.7 million in property expenses primarily as a result of an increase in certain recurring operating costs primarily related to property management expenses, insurance, other service-related costs and $0.5 million of non-recurring real estate taxes; and


•	An increase in real estate taxes of $1.1 million primarily as a result of a net decrease of $0.5 million of property tax refunds received that related to prior periods and customary real estate tax increases;


•	An increase in rental income of $1.4 million due to additional rental revenue resulting from an increase in tenant renewals and new leases at higher rental rates, partially offset by a decrease in average occupancy of 1.8%, from 92.0% for the six months ended June 30, 2012, to 90.2% for the six months ended June 30, 2013;


•	An increase in tenant reimbursements of $0.7 million primarily resulting from an increase in reimbursable property expenses and real estate taxes;


•	An increase of $5.1 million attributable to the Stabilized Redevelopment Properties; and


•	An increase of $3.1 million attributable to the Other Properties primarily resulting from income generated in 2013 from:


•	one redevelopment property in lease-up that was 50% occupied at June 30, 2013. The tenant took occupancy of this space in June 2012; and


•	one redevelopment property in lease-up that was 55% occupied at June 30, 2013. The tenant took occupancy of this space in July 2012.

Other Expenses and Income

General and Administrative Expenses

General and administrative expenses increased $1.5 million, or 8.4%, for the six months ended June 30, 2013 compared to the six months ended June 30, 2012 primarily attributable to an increase in compensation expense related to the February 2012 stock option grants made to our senior management team, higher payroll costs associated with the March 2012 and April 2013 renegotiations of our Chief Executive Officer's and Chief Operating Officer's employment agreements and an increase in payroll and administrative costs associated with the growth of the Company.

Depreciation and Amortization

Depreciation and amortization increased by $27.0 million, or 37.1%, for the six months ended June 30, 2013 compared to the six months ended June 30, 2012, primarily related to the Acquisition Properties.

Interest Expense



	Six Months Ended June 30,
	2013			2012			Dollar Change			Percentage Change
	($ in thousands)
Gross interest expense	$	55,380		$	48,483		$	6,897		14.2	%

Interest expense	$	39,168		$	40,318		$	(1,150	)	(2.9	)%

Gross interest expense, before the effect of capitalized interest, increased $6.9 million, or 14.2%, for the six months ended June 30, 2013 compared to the six months ended June 30, 2012 resulting from an increase in our average outstanding debt balances partially offset by a decrease in our weighted average GAAP effective interest rate, which includes the impact of debt discounts and premiums, from approximately 5.7% during the six months ended June 30, 2012 to approximately 4.8% during the six months ended June 30, 2013.

Capitalized interest increased $8.0 million, or 98.6%, for the six months ended June 30, 2013 compared to the six months ended June 30, 2012 primarily attributable to an increase in our development and redevelopment activity, which resulted in higher average asset balances qualifying for interest capitalization.

Liquidity and Capital Resources of the Company

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

The Company's business is operated primarily through the Operating Partnership. Distributions from the Operating Partnership are the Company's 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 revolving credit facility, are adequate for it to make its distribution payments to the Company and, in turn, for the Company to make its dividend payments to its preferred and common stockholders for the next twelve months. Cash flows from operating activities generated by the Operating Partnership for the three and six months ended June 30, 2013 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, 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 is required by the Operating Partnership's partnership agreement to contribute 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 revolving credit facility, to develop new or existing properties, to make acquisitions of properties or portfolios of properties, or for general corporate purposes.

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

Distribution Requirements

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

The Company intends to continue to make, but has not committed to make, regular quarterly cash distributions to common stockholders and common unitholders from cash flow from operating activities. All such distributions are at the discretion of the board of directors. The Company has historically distributed amounts in excess of our taxable income resulting in a return of capital to its stockholders and the Company currently believes it has the ability to maintain distributions at the 2012 levels to meet its REIT requirements for 2013. The Company considers market factors and its performance in addition to REIT requirements in determining our distribution levels. Amounts accumulated for distribution to stockholders are invested primarily in interest−bearing accounts and short−term interest−bearing securities, which are consistent with the Company's intention to maintain its qualification as a REIT. Such investments may include, for example, obligations of the Government National Mortgage Association, other governmental agency securities, certificates of deposit, and interest−bearing bank deposits.

On May 23, 2013, the Board of Directors declared a regular quarterly cash dividend of $0.35 per common share payable on July 17, 2013 to stockholders of record on June 28, 2013 and caused a $0.35 per Operating Partnership unit cash distribution to be paid in respect of the Operating Partnership's common limited partnership interests, including those owned by the Company. The total quarterly dividends and distributions paid on July 17, 2013 was $27.1 million.

On May 23, 2013, the Board of Directors declared a dividend of $0.42969 per share on the Series G Preferred Stock and $0.39844 per share on the Series H Preferred Stock for the period commencing on and including May 15, 2013 and ending on and including August 14, 2013. The dividend will be payable on August 15, 2013 to Series G Preferred and Series H Preferred stockholders of record on July 31, 2013. The quarterly dividends payable on August 15, 2013 to Series G and Series H Preferred stockholders total $3.3 million.

Capitalization

As of June 30, 2013, our total debt as a percentage of total market capitalization was 33.3% and our total debt and liquidation value of our preferred equity as a percentage of total market capitalization was 36.3%, which was calculated based on the closing price per share of the Company's common stock of $53.01 on June 30, 2013 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 revolving credit facility and term loan facility;


•	Proceeds from additional secured or unsecured debt financings;


•	Proceeds from public or private issuance of debt or equity securities; and


•	Proceeds from the disposition of nonstrategic assets through our capital recycling program.

Liquidity Uses


•	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;


•	Development and redevelopment costs; and


•	Outstanding debt repurchases.

General Strategy

Our general strategy is to maintain a conservative balance sheet with a top 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. We believe our conservative leverage and staggered debt maturities provide us with financial flexibility and enhances our ability to obtain additional sources of liquidity if necessary, and, therefore, we are well−positioned to refinance or repay maturing debt and to pursue our strategy of seeking attractive acquisition opportunities, which we may finance, as necessary, with future public and private issuances of debt and equity securities.

Summary of 2013 Funding Transactions

We continue to be active in the capital markets to finance our acquisition and development activity and our continued desire to improve our debt maturities and lower our overall weighted average cost of capital. This was primarily a result of the following transactions:

Capital Markets

•

During the six months ended June 30, 2013 we issued and sold a total of 814,408 of our common stock shares under our at−the−market stock offering program at a weighted average price of $53.66 per share before selling commissions. The net offering proceeds, after deducting sales agent compensation, of approximately $42.8 million were contributed to the Operating Partnership (see "— Liquidity Sources" below for additional information).


•	In January 2013, the Operating Partnership issued unsecured senior notes in a public offering with an aggregate principal balance of $300.0 million that are scheduled to mature on January 15, 2023. The unsecured senior notes require semi-annual interest payments each January and July based on a stated annual interest rate of 3.800%.

Debt Activity

•

During the three months ended March 31, 2013, the Operating Partnership assumed a secured mortgage loan with a principal balance of $83.9 million that was recorded at fair value resulting in a premium of $11.6 million in connection with an acquisition. We also repaid a secured mortgage loan with an outstanding principal balance of $83.1 million that was scheduled to mature in April 2013 (see Notes 2 and 5 to our consolidated financial statements included in this report for additional information).

After the effect of these aforementioned transactions, as of June 30, 2013, we had approximately $107.8 million of cash on hand and no outstanding borrowings on our revolving credit facility.

Liquidity Sources

Credit Facility

The following table summarizes the balance and terms of our revolving credit facility as of June 30, 2013 and December 31, 2012, respectively:



	June 30, 2013		December 31, 2012
	(in thousands)
Outstanding borrowings⁽¹⁾	$	—	$	185,000

Maturity date⁽⁵⁾	April 2017

________________________


(1)	As of June 30, 2013, there were no outstanding borrowings on the revolving credit facility

(2) We may elect to borrow, subject to bank approval, up to an additional $200.0 million under an accordion feature under the terms of the revolving credit facility.


(3)	The revolving credit facility interest rate was calculated based on an annual rate of LIBOR plus 1.450% as of both June 30, 2013 and December 31, 2012. No interest rate is shown as of June 30, 2013 because no borrowings were outstanding.


(4)	The facility fee is paid on a quarterly basis and is calculated based on the total borrowing capacity. In addition to the facility fee, we also incurred debt origination and legal costs of approximately $10.2 million that are currently being amortized through the maturity date of the revolving credit facility.


(5)	Under the terms of the revolving credit facility, we may exercise an option to extend the maturity date by one year.

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

Capital Recycling Program

In connection with our capital recycling program, we continuously evaluate opportunities for the potential disposition of properties and undeveloped land in our portfolio with the intent of recycling the proceeds generated from the dispositions of non-strategic or lower return assets into capital used to fund new operating and development acquisitions, to finance development and redevelopment expenditures, to repay long-term debt and for other general corporate purposes. As part of our strategy, we intend, when practical, to enter into like-kind exchanges under Section 1031 of the Code to defer some or all of the taxable gains on the sales, if any, for federal and state income tax purposes.

As part of our capital recycling program, we completed the sale of one office building to an unaffiliated third party during the three months ended June 30, 2013. Cash proceeds totaled approximately $14.7 million, resulting in a gain on sale of approximately $0.4 million (see Note 2 to our consolidated financial statements included in this report for additional information). In addition, we anticipate that we could dispose of approximately $150 million - $300 million of additional operating properties and/or undeveloped land during the next 12 -18 months in connection with our capital recycling program.

The timing of any potential future disposition transactions will depend on market conditions and other factors including but not limited to our capital needs and our ability to defer some or all of the taxable gains on the sales. We cannot assure you that we will dispose of any additional properties, or that future acquisitions and/or dispositions, if any, will qualify as like−kind exchange under Section 1031 of the Code.

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 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 is required by the Operating Partnership's partnership agreement to contribute 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 revolving credit facility, to develop new or existing properties, to make acquisitions of properties or portfolios of properties, or for general corporate purposes.

As of June 30, 2013, 7.0% of our debt bore interest at variable rates which was incurred under the term loan facility. The variable interest rate payments are based on LIBOR plus a spread of 1.750% as of June 30, 2013. The information in the table above reflects our projected interest rate obligations for these variable−rate payments based on outstanding principal balances as of June 30, 2013, the scheduled interest payment dates, and the contractual maturity dates.


(6)	Reflects minimum lease payments through the contractual lease expiration date before the impact of extension options.


(7)	Amounts represent commitments under signed leases and contracts for operating properties, excluding tenant-funded tenant improvements. The timing of these expenditures may fluctuate.

(8)

Amounts represent commitments under signed leases for pre-leased development projects and contractual commitments for lease-up projects and projects under construction as of June 30, 2013. The timing of these expenditures may fluctuate based on the ultimate progress of construction. This table also reflects the November 2012 exercise of the purchase option to acquire the land under a ground lease at one of our redevelopment properties before the end of 2013 for a purchase price of $27.5 million to be paid upon closing.

Other Potential Liquidity Uses

In 2012, we acquired 14 buildings for approximately $454.8 million in cash, and through June 30, 2013, we have acquired two buildings for approximately $85.7 million in cash. All of these transactions were funded through various capital raising activities and, in selected instances, the assumption of existing indebtedness. In addition, in 2012, we acquired six development property project opportunities for approximately $333.9 million in cash and other assumed liabilities. We continually evaluate acquisition and development opportunities as they arise.

In addition to ongoing and potential acquisitions of office properties, we have increased our focus on the acquisition of undeveloped land and development and redevelopment opportunities. As of June 30, 2013, we had five development projects under construction. These projects have a total estimated investment of approximately $856.5 million, of which we have incurred approximately $410.5 million as of June 30, 2013. In addition, we currently have additional development projects that we may commence construction on in the remainder of 2013. If these projects commence, we could invest between $90 million and $110 million in addition to the above commitments. This estimate is based on market conditions and our anticipation of project approvals. Actual costs could vary depending on changes in circumstances. Ultimate timing of these expenditures may fluctuate given the ultimate progress and leasing status of the projects.

As of the filing date of this report, we are in various stages of negotiation on other potential future acquisition opportunities, including an operating property. We expect that any material acquisitions or development activities will be funded with borrowings under the revolving credit facility, the public or private issuance of debt or equity securities, the disposition of assets under our capital recycling program or through the assumption of existing debt.

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

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

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


•	Decreases in our cash flows from operations, which could create further dependence on the revolving credit facility;


•	An increase in the proportion of variable-rate debt, which could increase our sensitivity to interest rate fluctuations in the future; and


•	A decrease in the value of our properties, which could have an adverse effect on the Operating Partnership's ability to incur additional debt, refinance existing debt at competitive rates, or comply with its existing debt obligations.

In addition to the factors noted above, the Operating Partnership's credit ratings are subject to ongoing evaluation by credit rating agencies and may be changed or withdrawn by a rating agency in the future if, in its judgment, circumstances warrant. In the event that the Operating Partnership's credit ratings are downgraded, we may incur higher borrowing costs and may experience difficulty in obtaining additional financing or refinancing existing indebtedness.

Debt Covenants

The revolving credit facility, 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. Key existing financial covenants and their covenant levels include:



Revolving Credit Facility and Term Loan Facility (as defined in the applicable Credit Agreements):	Covenant Level	Actual Performance at June 30, 2013
Total debt to total asset value	less than 60%	37%
Fixed charge coverage ratio	greater than 1.5x	2.3x
Unsecured debt ratio	greater than 1.67x	2.40x
Unencumbered asset pool debt service coverage	greater than 2.0x	3.4x


Unsecured Senior Notes due 2015, 2018, 2020 and 2023 (as defined in the applicable Indentures):
Total debt to total asset value	less than 60%	42%
Interest coverage	greater than 1.5x	3.9x
Secured debt to total asset value	less than 40%	11%
Unencumbered asset pool value to unsecured debt	greater than 150%	251%

The Operating Partnership was in compliance with all its debt covenants as of June 30, 2013. Our current expectation is that the Operating Partnership will continue to meet the requirements of its debt covenants in both the short and long term. However, in the event of a renewed economic slow down or continued volatility in the credit markets, there is no certainty that the Operating Partnership will be able to continue to satisfy all the covenant requirements.

Consolidated Historical Cash Flow Summary

Our historical cash flow activity for the six months ended June 30, 2013 as compared to the six months ended June 30, 2012 is as follows:



	Six Months Ended June 30,
	2013			2012			Dollar Change			Percentage Change
	($ in thousands)
Net cash provided by operating activities	$	107,004		$	78,633		$	28,371		36.1	%
Net cash used in investing activities	(20,622		)	(301,592		)	280,970			(93.2	)%
Net cash provided by financing activities	4,741			236,293			(231,552		)	(98.0	)%

Operating Activities

Our cash flows from operations 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 and related financing activities, and other general and administrative costs. Our net cash provided by operating activities increased by $28.4 million, or 36.1%, for the six months ended June 30, 2013 compared to the six months ended June 30, 2012 primarily as a result of an increase in cash Net Operating Income generated from our Acquisition Portfolio. See additional information under the caption "−Results of Operations."

Investing Activities

Our cash flows from investing activities is generally comprised of uses to fund property, development and redevelopment acquisitions, recurring and nonrecurring capital expenditures for our operating properties, and development and redevelopment projects, net of proceeds received from property dispositions. Our net cash used by investing activities decreased by $281.0 million, or 93.2%, for the six months ended June 30, 2013 compared to the six months ended June 30, 2012. The net decrease was primarily attributable to the receipt of $228.3 million of restricted cash from escrow during the six months ended June 30, 2013 related to proceeds from the sale of our industrial portfolio that was set aside at December 31, 2012 to facilitate Section 1031 Exchanges, a decrease of approximately $263.1 million of cash paid for acquisitions as compared to the prior period, and and a decrease of $128.8 million of net proceeds received from dispositions as compared to the prior period. This net decrease was offset by an increase of $99.1 million attributable to the increased activity in our redevelopment and development activity.

Financing Activities

Our net cash provided by financing activities is principally impacted by our capital raising activities, net of dividends and distributions paid to common and preferred security holders. Net cash provided by financing activities decreased by $231.6 million, or 98.0%, for the six months ended June 30, 2013 compared to the six months ended June 30, 2012 primarily due to the timing of significant equity raising activities totaling approximately $378.1 million in the prior year period offset by lower proceeds generated from debt financing activities generated for the six months ended June 30, 2013 as compared to the six months ended June 30, 2012.

Off-Balance Sheet Arrangements

As of June 30, 2013 and as of the date this report was filed, we did not have any off-balance sheet transactions, arrangements, or obligations, including contingent obligations.

Non-GAAP Supplemental Financial Measure: Funds From Operations

We calculate FFO in accordance with the White Paper on FFO approved by the Board of Governors of NAREIT. The White Paper defines FFO as net income or loss calculated in accordance with GAAP, excluding extraordinary items, as defined by GAAP,

gains and losses from sales of depreciable real estate and impairment write−downs associated with depreciable real estate, plus real estate-related depreciation and amortization (excluding amortization of deferred financing costs and depreciation of non-real estate assets), and after adjustment for unconsolidated partnerships and joint ventures. Our calculation of FFO includes the amortization of deferred revenue related to tenant-funded tenant improvements and excludes the depreciation of the related tenant improvement assets.

We believe that FFO is a useful supplemental measure of our operating performance. The exclusion from FFO of gains and losses from the sale of operating real estate assets allows investors and analysts to readily identify the operating results of the assets that form the core of our activity and assists in comparing those operating results between periods. Also, because FFO is generally recognized as the industry standard for reporting the operations of REITs, it facilitates comparisons of operating performance to other REITs. However, other REITs may use different methodologies to calculate FFO, and accordingly, our FFO may not be comparable to all other REITs.

Implicit in historical cost accounting for real estate assets in accordance with GAAP is the assumption that the value of real estate assets diminishes predictably over time. Because 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 six months ended June 30, 2013 and 2012:



	Three Months Ended June 30,						Six Months Ended June 30,
	2013			2012			2013			2012
	(in thousands)
Net income (loss) available to common stockholders	$	6,633		$	(800	)	$	5,730		$	66,740

(1)	Reported amounts are attributable to common stockholders and common unitholders.


(2)	FFO includes amortization of deferred revenue related to tenant-funded tenant improvements of $2.5 million and $2.2 million for the three months ended June 30, 2013 and 2012 respectively, and $5.0 million and $4.5 million for the six months ended June 30, 2013 and 2012 respectively.


ITEM 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary market risk we face is interest rate risk. We 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 June 30, 2013 and December 31, 2012, we did not have any interest−rate sensitive derivative assets or liabilities.

Information about our changes in interest rate risk exposures from December 31, 2012 to June 30, 2013 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 June 30, 2013, approximately 7.0% of our total outstanding debt of $2.2 billion was subject to variable interest rates. The remaining 93.0% 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, 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 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 the liability component of our 4.25% Exchangeable Notes by performing discounted cash flow analyses using an appropriate market interest rate based upon spreads for our publicly traded debt. 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 to our consolidated financial statements included in this report for additional information on the fair value of our financial assets and liabilities as of June 30, 2013 and December 31, 2012.

As of June 30, 2013, the total outstanding balance of our variable−rate debt was comprised of borrowings on our unsecured term loan facility of $150.0 million, which was indexed to LIBOR plus a spread of 1.750%. As of December 31, 2012, the total outstanding balance of our variable−rate debt was comprised of borrowings on our revolving credit facility of $185.0 million and borrowings on our unsecured term loan facility of $150.0 million, which were indexed to LIBOR plus a spread of 1.450% (weighted average interest rate of 1.66%) and 1.750% (weighted average interest rate of 1.97%), respectively. Assuming no changes in the outstanding balance of our existing variable−rate debt as of June 30, 2013, a 100 basis point increase in the LIBOR rate would increase our projected annual interest expense, before the effect of capitalization, by approximately $1.5 million. Comparatively, if interest rates were 100 basis points higher as of December 31, 2012, our projected annual interest expense, before the effect of capitalization, would have been $3.4 million higher.

The total carrying value of our fixed−rate debt, including our 4.25% Exchangeable Notes, was approximately $2.0 billion and $1.7 billion as of June 30, 2013 and December 31, 2012, respectively. The total estimated fair value of our fixed−rate debt was approximately $2.1 billion and $1.9 billion as of June 30, 2013 and December 31, 2012, respectively. 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 $87.7 million, or 4.1%, as of June 30, 2013. 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 $71.8 million, or 3.8%, as of December 31, 2012.

PART II-OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We and our properties are subject to routine litigation incidental to our business. These matters are generally covered by insurance. As of June 30, 2013, we are not a defendant in, and our properties are not subject to, any legal proceedings that we believe, if determined adversely to us, would have a material adverse effect upon our financial condition, results of operations, or cash flows.


ITEM 1A.	RISK FACTORS

Joint venture investments could be adversely affected by our lack of sole decision-making authority, our reliance on co-venturers' financial condition, and disputes between us and our co-venturers and could expose us to potential liabilities and losses.

As described more fully in Note 2 to our consolidated financial statements included in this report, on June 27, 2013, we entered into an agreement with an unaffiliated third party and formed a new consolidated subsidiary, Redwood City Partners, LLC, to ultimately develop and operate a new office complex in Redwood City, California. We are the managing member and expect to eventually own 93% of Redwood City Partners, LLC. In addition to this venture, we may continue to co-invest in the future with third parties through partnerships, joint ventures or other entities, or through acquiring non-controlling interests in, or sharing responsibility for, managing the affairs of a property, partnership, joint venture or other entity, which may subject us to risks that may not be present with other methods of ownership, including the following:


•	We would not be in a position to exercise sole decision-making authority regarding the property, partnership, joint venture or other entity, which would allow for impasses on decisions that could restrict our ability to sell or transfer our interests in such entity or such entity's ability to transfer or sell its assets.


•	Partners or co-venturers might become bankrupt or fail to fund their share of required capital contributions, which could delay construction or development of a property or increase our financial commitment to the joint venture.


•	Partners or co-venturers may pursue economic or other business interests, policies or objectives that are competitive or inconsistent with ours.


•	If we become a limited partner or non-managing member in any partnership or limited liability company, and such entity takes or expects to take actions that could jeopardize our status as a REIT or require us to pay tax, we may be forced to dispose of our interest in such entity.


•	Disputes between us and partners or co-venturers may result in litigation or arbitration that would increase our expenses and prevent our officers and/or directors from focusing their time and effort on our business.


•	We may, in certain circumstances, be liable for the actions of our third-party partners or co-venturers.


•	Joint venture debt is the liability of the joint venture, may be secured by a mortgage on the joint venture property, and a default by the joint venture under its debt obligations may expose us to liability under a guaranty or letter of credit.
