MPG OFFICE TRUST, INC.

SUPPLEMENT NO. 1 DATED AUGUST 7, 2013

TO POST-EFFECTIVE AMENDMENT NO. 4 DATED JUNE 12, 2013

This document supplements, and should be read in conjunction with, our Post-Effective Amendment No. 4 dated June 12, 2013 relating to the potential sale of up to 25,526 shares of our common stock by the selling security holders named in the prospectus should they exchange their units representing common limited partnership units in MPG Office, L.P. for common stock (the “prospectus”). Capitalized terms used in this supplement have the same meaning as set forth in the prospectus. The purpose of this supplement is to disclose:

• “Risk Factors” provided in Part II, Item 1A of our Quarterly Report on Form 10-Q for the three and six months ended June 30, 2013, filed with the U.S. Securities and Exchange Commission (the “SEC”) on August 7, 2013;

• Selling Security Holder as of August 7, 2013;

• “Management’s Discussion and Analysis of Financial Condition and Results of Operations” provided in Part I, Item 2 of our Quarterly Report on Form 10-Q for the three and six months ended June 30, 2013, filed with the SEC on August 7, 2013; and

• Our unaudited consolidated financial statements as of and for the three and six months ended June 30, 2013, as provided in Part I, Item 1 of our Quarterly Report on Form 10-Q, filed with the SEC on August 7, 2013.

RISK FACTORS

As used in these risk factors, the terms “MPG Office Trust,” the “Company,” “us,” “we” and “our” refer to MPG Office Trust, Inc.

Some of the risks and uncertainties that may cause our actual results, performance, liquidity or achievements to differ materially from those expressed or implied by forward-looking statements include, among others, the following:

• Our ability to consummate the merger and the timing of the closing of the merger;

• Our liquidity situation, including our failure to obtain additional capital or extend or refinance debt maturities;

• Our failure to reduce our significant level of indebtedness;

• Risks associated with the timing and consequences of loan defaults;

• Risks associated with our loan modification and asset disposition efforts, including potential tax ramifications;

• Risks associated with our ability to dispose of properties with potential value above the debt, if and when we decide to do so, at prices or terms set by or acceptable to us;

• Decreases in the market value of our properties;

• Decreased rental rates, increased lease concessions or failure to achieve occupancy targets;

• Defaults on or non-renewal of leases by tenants;

• Our dependence on significant tenants;

• Adverse economic or real estate developments in Southern California, particularly in the Los Angeles Central Business District;

• Disruption of credit markets or a global economic slowdown;

• Potential loss of key personnel (most importantly, members of senior management);

• Increased interest rates and operating costs;

• Our failure to maintain our status as a real estate investment trust;

• Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited under certain circumstances;

• Environmental uncertainties and risks related to earthquakes and other natural disasters;

• Future terrorist attacks in the U.S.;

• Risks associated with our organizational structure; and

• Changes in real estate and zoning laws and increases in real property tax rates.

1

Set forth below are some (but not all) of the factors that could adversely affect our performance and financial condition. We believe the following risks are material to our stockholders. You should carefully consider the following factors in evaluating our company, our properties and our business. The occurrence of any of the following risks might cause our stockholders to lose all or part of their investment. For the purposes of this section, the term “stockholders” means the holders of shares of our common stock and of our 7.625% Series A Cumulative Redeemable Preferred Stock (the “Series A preferred stock”).

Failure to complete the merger could negatively impact our stock price and our future business and financial results.

Completion of the merger is subject to the satisfaction or waiver of various conditions, including receipt of various approvals and authorizations, including certain consents from our lenders, and the absence of any order, injunction or decree preventing the completion of the merger. There is no assurance that all of the various conditions will be satisfied or waived. If the merger is not completed, the trading price of our common stock may decline, to the extent that the current market prices reflect a market assumption that the merger will be completed. In addition, our business and operations may be harmed to the extent that tenants, vendors and others believe that we cannot effectively operate in the marketplace on a stand-alone basis, or there is tenant or employee uncertainty surrounding the ability of our Company to operate on a stand-alone basis.

If the merger is not completed for any reason, we will be subject to numerous risks, including the following:

• Being required, under certain circumstances, including if we sign a definitive agreement with respect to a superior proposal from another potential buyer, to pay a termination fee of $17.0 million and an expense reimbursement of up to $6.0 million of Brookfield’s costs and expenses in connection with the Merger Agreement;

• Having incurred certain costs relating to the merger that are payable whether or not the merger is completed, including legal, accounting, financial advisor and printing fees; and

• Having had the focus of management directed toward the merger and integration planning instead of on our core business and other opportunities that could have been beneficial to us.

In addition, we would not realize any of the expected benefits of having completed the merger. If the merger is not completed, we cannot assure our stockholders that these risks will not materialize or materially adversely affect our business, financial condition, results of operations and stock price.

Provisions of the Merger Agreement may deter alternative business combinations and could negatively impact our stock price if the Merger Agreement is terminated in certain circumstances.

Restrictions in the Merger Agreement on solicitation generally prohibit us from soliciting any acquisition proposal or offer for a merger or business combination with any other party, including a proposal that might be advantageous to our stockholders when compared to the terms and conditions of the merger. If the merger is not completed, we may not be able to conclude another merger, sale or combination on as favorable terms, in a timely manner, or at all. If the Merger Agreement is terminated, the Company, in certain specified circumstances, may be required to pay a termination fee of $17.0 million. In addition, under certain circumstances, the Company may be required to pay an expense fee of up to $6.0 million. These provisions may deter third parties from proposing or pursuing alternative business combinations that might result in greater value to our stockholders than the merger.

2

Uncertainty regarding the merger may cause tenants, vendors and others to delay or defer decisions concerning their business with our Company, which may negatively impact our results of operations going forward if the merger is not completed.

Because the merger is subject to several closing conditions, uncertainty exists regarding the completion of the merger. This uncertainty may cause tenants, vendors and others to delay or defer decisions concerning their business with our Company, which could negatively affect our business, financial condition and results of operations.

If the merger is not completed, we could suffer a number of consequences that may adversely affect our business, results of operations and stock price, including the following:

• Activities relating to the merger and related uncertainties may lead to a loss of revenue that we may not be able to recoup if the merger does not occur;

• We would remain liable for our costs related to the merger, such as legal fees and financial advisor fees;

• We may not be able to refinance the indebtedness at certain of our properties as it comes due, or we may be forced to return properties to lenders;

• We may suffer significant employee attrition, including attrition of key employees;

• We may not be able to continue our present level of operations and therefore would have to scale back our operations and consider additional cost reductions; and

• We may not be able to take advantage of alternative business opportunities or effectively respond to competitive pressures.

Additional material risk factors are discussed in this prospectus supplement and in our Annual Report on Form 10-K filed with the SEC on March 18, 2013. Those risks are also relevant to our performance and financial condition. Moreover, we operate in a highly competitive and rapidly changing environment. New risk factors emerge from time to time, and it is not possible for management to predict all such risk factors, nor can it assess the impact of all such risk factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results.

SELLING SECURITY HOLDER

The “selling security holder” is the person or entity who may receive shares of our common stock upon exchange of common units. The following table provides the name of the selling security holder, the maximum number of shares of our common stock issuable to the selling security holder in the exchange and the aggregate number of shares of our common stock that will be owned by the selling security holder after the exchange. The number of shares in the following table represents the number of shares of our common stock into which common units held by the selling security holder are exchangeable. Since the selling security holder may sell all, some or none of its shares, we cannot estimate the aggregate number of shares that the selling security holder will offer pursuant to this prospectus or that the selling security holder will own upon completion of the offering to which this prospectus relates.

The selling security holder named below may from time to time offer the shares of our common stock offered by this prospectus:

	Shares of Our Common Stock Owned Prior to the Exchange	Maximum Number of Shares of Our Common Stock Issuable in the Exchange and Available for Resale	Shares of Our Common Stock Owned Following the Exchange (1)		Maximum Number of Shares of Our Common Stock to be Resold	Shares of Our Common Stock Owned after Resale (2)
			Shares	Percent		Shares	Percent
Thomas Master Investments, LLC	—	25,526	25,526	*	25,526	—	—

__________

* Less than 1.0 percent.

(1) Assumes that we exchange the common units of the selling security holder for shares of our common stock. The percentage ownership is determined by taking into account the issuance and sale of shares of our common stock issued in exchange for common units of only such selling security holder. Also assumes that no transactions with respect to our common stock or common units occur other than the exchange. There were 57,458,874 shares of our common stock outstanding as of August 2, 2013.

(2) Assumes the selling security holder sells all of its shares of our common stock offered pursuant to this prospectus. The percentage ownership is determined by taking into account the issuance and sale of shares of our common stock issued in exchange for common units of only such selling security holder.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

As used in this Management’s Discussion and Analysis of Financial Condition and Results of Operations, the terms “MPG Office Trust,” the “Company,” “us,” “we” and “our” refer to MPG Office Trust, Inc.

Overview and Background

We are a self-administered and self-managed real estate investment trust (“REIT”), and we operate as a REIT for federal income tax purposes. We are the largest owner and operator of Class A office properties in the Los Angeles Central Business District (“LACBD”).

Through our controlling interest in MPG Office, L.P. (the “Operating Partnership”), of which we are the sole general partner and hold an approximate 99.96% interest, and the subsidiaries of the Operating Partnership, including MPG Office Trust Services, Inc. and its subsidiaries (collectively known as the “Services Company”), we own, manage and lease real estate located primarily in the greater Los Angeles area of California. This real estate primarily consists of office properties, parking garages and land parcels.

As of June 30, 2013, the Operating Partnership indirectly owns five office properties and on- and off-site parking garages (the “Total Portfolio”). We hold an approximate 99.96% interest in the Operating Partnership, and therefore do not completely own the Total Portfolio. The aggregate square footage of the Total Portfolio has not been reduced to reflect our limited partners’ 0.04% share of the Operating Partnership.

As of June 30, 2013, the Total Portfolio included the following:

• Four office properties located in the LACBD totaling 5.0 million square feet that were 84.8% leased;

• One office property located in Pasadena, California totaling 0.2 million square feet that was 100.0% leased; and

• Parking garages located in the LACBD totaling 2.0 million square feet, which accommodate 6,496 vehicles.

We directly manage the properties in the Total Portfolio through the Operating Partnership and/or the Services Company. We receive income primarily from rental revenue (including tenant reimbursements) from our office properties, and to a lesser extent, from our parking garages.

On April 24, 2013, the Company and the Operating Partnership entered into a definitive merger agreement pursuant to which a newly formed fund controlled by Brookfield Office Properties Inc. (“Brookfield”) agreed to acquire the Company. The merger transaction was approved by the Company’s common stockholders on July 17, 2013. At the closing of the transaction, the Company’s common stockholders will receive merger consideration of $3.15 in cash per share, without interest and less any required withholding tax. The Company expects the merger to close in the third quarter of 2013, following fulfillment of the conditions to closing, including receipt of required lender consents. See “Merger with Brookfield.”

Merger with Brookfield

Merger Agreement

On April 24, 2013, the Company and the Operating Partnership entered into a definitive merger agreement (the “Merger Agreement”) pursuant to which a newly formed fund, Brookfield DTLA Holdings L.P., a Delaware limited partnership (which was subsequently converted into a Delaware limited liability company on May 10, 2013) (“Brookfield DTLA”), controlled by Brookfield agreed to acquire the Company. The Company will merge with and into Brookfield DTLA Fund Office Trust Inc., a Maryland corporation (“REIT Merger Sub”), with REIT Merger Sub surviving the merger. Brookfield DTLA will have the option, in its sole discretion and without requiring further consent, to request that the Company agree to change the direction of the merger so that the Company is the surviving entity. The Merger Agreement also provides for a merger of Brookfield DTLA Fund Properties LLC, a Maryland limited liability company (“Partnership Merger Sub”), with and into the Operating Partnership, with the Operating Partnership surviving the merger.

On July 17, 2013, the Company’s common stockholders voted to approve the merger of the Company with REIT Merger Sub and the other transactions contemplated by the Merger Agreement (collectively, the “merger”). The Company expects the merger to close in the third quarter of 2013, following fulfillment of the conditions to closing, including receipt of required lender consents.

Under the terms of the Merger Agreement, each issued and outstanding share of our common stock will be automatically converted into, and canceled in exchange for, the right to receive $3.15 in cash, without interest and less any required withholding tax, (the “merger consideration”) at the closing of the merger. Each issued and outstanding share of restricted common stock will cease to be subject to forfeiture and will be canceled in exchange for the right to receive the merger consideration. Each issued and outstanding restricted stock unit will receive the merger consideration per share for each outstanding restricted stock unit. Each Company stock option granted under a Company plan, whether or not then exercisable, will be canceled in exchange for the right to receive the excess, if any, of the merger consideration over the exercise price per share of such Company stock option. If the exercise price per share of any such Company stock option is equal to or greater than the merger consideration, such Company stock option will be canceled without payment.

Additionally, a subsidiary of Brookfield has commenced a tender offer to purchase, subject to certain conditions, all of the Company’s outstanding 7.625% Series A Cumulative Redeemable Preferred Stock, par value $0.01 per share (the “Company Preferred Shares”), for $25.00 per share in cash, without interest. Any Company Preferred Shares that are not tendered will be converted in the merger into new preferred shares of Brookfield DTLA Fund Office Trust Investor Inc., a Maryland corporation (“Sub REIT”), with rights, terms and conditions substantially identical to the rights, terms and conditions of the Company Preferred Shares.

In connection with the Merger Agreement, Brookfield has entered into a guarantee with respect to the obligations of its affiliates under the Merger Agreement, including the full performance and payment of all of the payment and/or monetary obligations and liabilities arising under or in connection with the Merger Agreement and the transactions contemplated thereby.

MPG OFFICE TRUST, INC.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

The Company and Brookfield DTLA have made certain customary representations, warranties and covenants in the Merger Agreement. The Company, among other things, subject to certain exceptions, covenanted: (i) to conduct its business in the ordinary course consistent with past practice during the interim period between the execution of the Merger Agreement and the consummation of the merger; and (ii) to not solicit, initiate or facilitate the making, submission or announcement of any acquisition proposal, or any proposal or offer that would reasonably be expected to lead to an acquisition proposal, or provide confidential information in connection with, any acquisition proposal.

The Merger Agreement contains certain termination rights for both the Company and Brookfield DTLA, including, among other bases for termination and subject to certain exceptions, if the merger has not been consummated on or before August 15, 2013, subject to (i) the Company’s right to an extension until September 16, 2013 and Brookfield DTLA’s right to extension until August 30, 2013, in each case if all the conditions to the closing, other than obtaining certain lender consents, have been satisfied or waived prior to August 15, 2013 and (ii) certain other extension rights further discussed below under “—Waiver and First Amendment to Merger Agreement.”

Waiver and First Amendment to Merger Agreement

On May 19, 2013, the Company, the Operating Partnership, Brookfield DTLA, Sub REIT, REIT Merger Sub and Partnership Merger Sub (Brookfield DTLA, Sub REIT, REIT Merger Sub and Partnership Merger Sub, collectively, the “Brookfield Parties”), entered into a waiver and first amendment to the Merger Agreement (the “Waiver and Amendment”).

Pursuant to the Waiver and Amendment, Brookfield DTLA has irrevocably waived its right to cash out non-tendered Company Preferred Shares. Accordingly, all Company Preferred Shares that are not validly tendered and accepted for payment in the tender offer will be converted into shares of 7.625% Series A Cumulative Redeemable Preferred Stock, par value $0.01 per share, of Sub REIT (collectively, the “Sub REIT Preferred Shares”), with rights, terms and conditions substantially identical to the rights, terms and conditions of the Company Preferred Shares.

The Waiver and Amendment also permits Brookfield DTLA to make amendments to the limited partnership agreement of the Operating Partnership in order to effectuate the provisions of the Merger Agreement relating to the potential investment in the Operating Partnership by DTLA Fund Holding Co., the conversion of general partner common units of the Operating Partnership into general partner common units of the Surviving Partnership, and the conversion of limited partner common units held by any subsidiary of the Company into Series B Partnership General Partner Units.

The Waiver and Amendment also clarifies that the tender offer Purchaser (as defined in the Merger Agreement) will not consummate the tender offer except immediately prior to the effective time of the merger unless both the Company and the tender offer Purchaser agree in writing.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

In addition, the Waiver and Amendment reflects certain changes relating to a registration statement on Form S-4 (the “Form S-4”) that Sub REIT filed with the U.S. Securities and Exchange Commission (“SEC”) in connection with the potential issuance of Sub REIT Preferred Shares to the holders of Company Preferred Shares. The Waiver and Amendment clarifies that, in the absence of an SEC stop order that is then in effect, the effectiveness of the Form S-4 is not a condition to the Brookfield Parties’ obligations to consummate the merger. However, if all the conditions to the obligations of the Brookfield Parties to consummate the merger have been satisfied (other than those required to be satisfied or waived at the closing of the merger) but either (i) the Form S-4 has not become effective or (ii) the SEC has issued a stop order that is in effect, then Brookfield DTLA will have the right to delay the closing until the earliest to occur of (A) the date specified by Brookfield DTLA in the written notice exercising this right, (B) one business day after the effectiveness of the Form S-4, (C) one business day after any stop order issued in respect of the Form S-4 has been lifted, reversed or otherwise terminated, and (D) September 25, 2013. If Brookfield DTLA exercises this right, (X) Brookfield DTLA will be deemed to have immediately and irrevocably waived all of the conditions to its obligations to close the merger, other than the conditions relating to the following: (1) the absence of a legal restraint prohibiting the consummation of the merger to the extent not related to a stop order suspending the effectiveness of the Form S-4, (2) performance by the Company and the Operating Partnership of their agreements and covenants under the Merger Agreement, but only if such failure to perform constitutes a willful and material breach of the Merger Agreement that results in a long-term adverse effect on the business of the Company and the Operating Partnership (a “willful and material breach”), and (3) the absence of a Material Adverse Effect (as defined in the Merger Agreement); and (Y) after August 15, 2013, Brookfield DTLA will be deemed to have irrevocably waived all conditions to its obligations to close the merger except for the condition related to the performance by the Company and the Operating Partnership of their agreements and covenants under the Merger Agreement, but only if such failure to perform constitutes a willful and material breach of the Merger Agreement.

The Waiver and Amendment further provides that if either the Form S-4 has not become effective or the SEC has issued a stop order suspending the effectiveness of the Form S-4, the Company may extend the Outside Date (as defined in the Merger Agreement) up to until October 31, 2013. Additionally, if Brookfield DTLA elects to exercise its right to delay the closing as discussed above, then (i) on or prior to August 15, 2013, Brookfield DTLA’s right to terminate the Merger Agreement due to the failure of the merger to be consummated by the Outside Date will be limited to situations where there is a legal restraint prohibiting the consummation of the merger (other than to the extent related to a stop order suspending the effectiveness of the Form S-4) or there is a Material Adverse Effect, and (ii) after August 15, 2013, Brookfield DTLA will be deemed to have waived irrevocably any right to terminate the Merger Agreement due to the failure of the merger to be consummated by the Outside Date.

On July 10, 2013, the Company, the Operating Partnership and the Brookfield Parties entered into a second amendment to the Merger Agreement to permit the Company to release third parties that were then subject to confidentiality agreements with the Company from any standstill or similar provision contained in such agreements.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Liquidity and Capital Resources

General

Our business requires continued access to adequate cash to fund our liquidity needs. Over the last several years, we have maintained our liquidity position through secured debt financings, cash-generating asset sales and asset dispositions at or below the debt in cooperation with our lenders, as well as reductions in leasing costs, discretionary capital expenditures, property operating expenses, and general and administrative expenses.

Sources and Uses of Liquidity

Our potential liquidity sources and uses are, among others, as follows:

	Sources		Uses
•	Unrestricted and restricted cash;	•	Property operations and corporate expenses;
•	Cash generated from operations;	•	Capital expenditures (including commissions and tenant improvements);
•	Asset dispositions;	•	Payments in connection with loans (including debt service, principal payment obligations and payments to extend, refinance, modify or exit loans);
•	Proceeds from public or private issuance of debt or equity securities;	•	Payment of potential federal and state income tax obligations;
•	Cash generated from the contribution of existing assets to joint ventures; and/or	•	Entitlement-related costs; and/or
•	Proceeds from additional secured or unsecured debt financings.	•	Distributions to common and preferred stockholders and unit holders.

Potential Sources of Liquidity—

We are working to address challenges to our liquidity position, particularly debt maturities, leasing costs and capital expenditures. We do not currently have committed sources of cash adequate to fund all of our potential needs, including our 2013 debt maturities. If we are unable to raise additional capital or sell assets, we may face challenges in repaying, extending or refinancing our existing debt (including our debt maturities) on favorable terms or at all, and we may be forced to give back assets to the relevant mortgage lenders. While we believe that access to future sources of significant cash will be challenging, we believe that we will have access to some of the liquidity sources identified above and that those sources will be sufficient to meet our near-term liquidity needs. On June 18, 2013, we sold US Bank Tower and the Westlawn off-site parking garage and received net proceeds of $103.0 million, a portion of which may potentially be used to make loan re-balancing payments on our upcoming 2013 debt maturities at KPMG Tower and 777 Tower. Additionally, on July 18, 2013, we sold Plaza Las Fuentes and received net proceeds of approximately $30 million, which may potentially be used to make loan re‑balancing payments on our upcoming 2013 debt maturities at KPMG Tower and 777 Tower. See “Subsequent Events.”

MPG OFFICE TRUST, INC.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Our ability to sell our properties to raise capital is not assured. Companies known to be liquidating assets in order to fund liquidity needs may lose negotiation and pricing power. Accordingly, if we are forced to sell properties to meet our liquidity requirements, we may be forced to sell at a discount to fair value. We believe that the concentration of our properties in downtown Los Angeles creates operating and leasing synergies that enhance the value of our company. Selling properties on a one-off basis to fund liquidity needs, therefore, may diminish those synergies and decrease the value of our remaining portfolio of properties. Our tax basis in each of our properties is substantially less than their fair value and, in some cases, the amount of indebtedness encumbering them. Accordingly, asset sales may cause us to be liable for material tax obligations. Asset sales also could require us to incur potentially significant transaction expenses even if our efforts to sell an asset are not successful. In addition, asset sales typically take significant time to complete, exposing us to additional market and economic risks.

Our ability to access the capital markets to raise capital is highly uncertain. Our substantial indebtedness may prevent us from being able to raise debt financing on acceptable terms or at all. We believe we are unlikely to be able to raise equity capital in the capital markets.

Future sources of significant cash are essential to our liquidity and financial position, and if we are unable to generate adequate cash from these sources we will have liquidity-related problems and will be exposed to material risks. In addition, our inability to secure adequate sources of liquidity could lead to our eventual insolvency. For a further discussion of risks associated with loan defaults, economic conditions, our liquidity position and our substantial indebtedness, see “Risk Factors” contained in this prospectus supplement and Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K filed with the SEC on March 18, 2013.

Unrestricted and Restricted Cash—

A summary of our cash position as of June 30, 2013 is as follows (in millions):

Unrestricted cash and cash equivalents	$	241.2
Restricted cash:
Leasing and capital expenditure reserves (1)	16.9
Tax, insurance and other working capital reserves	7.8
Prepaid rent reserves	8.2
Collateral accounts	2.5
Total restricted cash	35.4
Total cash	$	276.6

___________

(1) Our available leasing reserves at our LACBD properties total $15.2 million.

The leasing and capital expenditure, tax, insurance and other working capital, and prepaid rent reserves are held in restricted accounts by our lenders in accordance with the terms of our loan agreements.

10

MPG OFFICE TRUST, INC.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Other than at KPMG Tower, the leasing reserves at our LACBD properties have been exhausted in large part, and leasing costs will need to be funded primarily from property-generated cash flow. See “—Potential Uses of Liquidity—Capital Expenditures (Including Commissions and Tenant Improvements)” below.

Cash Generated from Operations—

Our cash generated from operations is primarily dependent upon (1) the occupancy level of our portfolio, (2) the rental rates achieved on our leases, and (3) the collectability of rent and other amounts billed to our tenants. Net cash generated from operations is tied to our level of operating expenses and other general and administrative costs, described below under “—Potential Uses of Liquidity.”

Occupancy levels. The following table presents the leased percentage as of June 30, 2013, and the expiring leased square feet expected to not be renewed for the remainder of 2013 and for the 2014 calendar year at our LACBD properties for leases in place as of June 30, 2013. The table does not include conversations with existing or new tenants that would potentially increase or decrease vacant square footage. Actual leased percentages as of December 31, 2013 and 2014 could vary materially from the adjusted lease percentages shown in the table below due to factors such as entry into new leases or future tenant non-renewals, early terminations or tenant defaults.

	As of June 30, 2013				Expiring Leased Square Feet, Net not Expected to be Renewed during 2013		Adjusted Leased Percentage at Dec. 31, 2013		Expiring Leased Square Feet, Net not Expected to be Renewed during 2014		Adjusted Leased Percentage at Dec. 31, 2014
	Net Building Rentable Square Feet	Vacant Square Feet	Leased Percentage
Office Properties
Gas Company Tower	1,370,239	288,240	79.0	%	(180,470	)	65.8	%	—		65.8	%
Wells Fargo Tower (1)	1,416,522	161,447	88.6	%	(115,995	)	80.4	%	(5,601	)	80.0	%
KPMG Tower	1,154,306	100,323	91.3	%	(71,258	)	85.1	%	(190,552	)	68.6	%

	4,959,570	752,696	84.8	%	(406,289	)	76.6	%	(196,153	)	72.7	%

__________

(1) As of June 30, 2013, Wells Fargo Bank had the right to contract up to an additional 23,506 square feet, which has not been taken into account in this analysis.

As of June 30, 2013, we had 4.2 million occupied square feet, or 84.8% of our net building rentable square feet, that is expected to decrease to 76.6% and 72.7%, on an adjusted basis, as of December 31, 2013 and 2014, respectively, based on our expectations of expiring leases that will not be renewed. Our overall occupancy rate has declined since our year-end 2012 level, and is expected to further decline during 2013 and 2014, for the following reasons (among others):

• We are experiencing aggressive competition from other property owners in the LACBD.

• Some of our current tenants are downsizing their space upon renewal.

• Our perceived liquidity challenges and loan defaults in prior years may have impacted potential tenants’ willingness to enter into leases with us.

11

MPG OFFICE TRUST, INC.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

• Economic conditions and stock market volatility have resulted in some companies shifting to a more cautionary mode with respect to leasing office space.

• Some of our current and potential tenants rely heavily on the availability of financing to support operating costs (including rent).

(1) Annualized rent represents the annualized monthly contractual rent under existing leases as of June 30, 2013. This amount reflects total base rent before any rent abatements as of June 30, 2013 and is shown on a net basis; thus, for any tenant under a partial gross lease, the expense stop, or under a fully gross lease, the current year operating expenses (which may be estimates as of such date), are subtracted from gross rent. Total abatements for leases in effect as of June 30, 2013 for the twelve months ending June 30, 2014 are approximately $7 million, or $1.69 per leased square foot.

(2) Current rent per leased square foot represents current base rent, divided by total leased square feet as of the same date.

(3) Rent per leased square foot at expiration represents base rent, including any future rent steps, and thus represents the base rent that will be in place at lease expiration.

(4) Includes tenants leasing on a month-to-month basis.

Rental Rates and Leasing Activity. Average asking rental rates in the LACBD were flat during the six months ended June 30, 2013. We believe that on average our in-place rents are generally at or above market in the LACBD. Because of market competition combined with economic volatility and uncertainty, we expect that rental rates (net of concessions) may remain flat or slightly decline during 2013.

The following table summarizes leasing activity at our LACBD properties for the six months ended June 30, 2013:

	Leasing Activity		Percentage Leased
Leased square feet as of December 31, 2012	5,010,221		78.4		%

(1) Represents the difference between (i) initial market rents on new and renewed leases and (ii) the cash rents on those spaces immediately prior to expiration or termination.

(2) Excludes new leases for space with more than twelve months of downtime and leases with early renewals commencing after June 30, 2014.

(3) Represents estimated cash rent growth adjusted for straight-line rents in accordance with U.S. generally accepted accounting principles (“GAAP”).

Collectability of rent from our tenants. Our rental revenue depends on collecting rent from tenants, and in particular from our major tenants. As of June 30, 2013, our major tenants represented 61.5% of the LACBD’s total annualized rental revenue. In the event of tenant defaults, we may experience delays in enforcing our rights as landlord and may incur substantial costs in pursuing legal possession of the tenant’s space and recovery of any amounts due to us from the tenant. This is particularly true in the case of the bankruptcy or insolvency of a major tenant or where the Federal Deposit Insurance Corporation is acting as receiver.

Asset Dispositions—

During the past several years, we have systematically disposed of assets in order to (1) preserve cash through the disposition of properties with current or projected negative cash flow and/or other potential near-term cash outlay requirements (including debt maturities) and (2) generate cash through the disposition of strategically-identified non-core properties with positive equity value. We may dispose of additional assets in the future in order to generate cash. However, we have a limited number of assets remaining that could be sold to generate net cash proceeds. If we choose to pursue such a disposition, we cannot assure you that such a disposition could be completed in a timely manner or on terms acceptable to us.

Cash-Generating Dispositions—

On June 18, 2013, we sold US Bank Tower and the Westlawn off-site parking garage and received net proceeds of $103.0 million, a portion of which may potentially be used to make loan re‑balancing payments on our upcoming 2013 debt maturities at KPMG Tower and 777 Tower.

On July 18, 2013, we sold Plaza Las Fuentes and received net proceeds of approximately $30 million, which may potentially be used to make loan re-balancing payments on our upcoming 2013 debt maturities at KPMG Tower and 777 Tower. See “Subsequent Events.”

Proceeds from Public or Private Issuance of Debt or Equity Securities—

Due to market conditions and our high leverage level, among other factors, it would be extremely difficult to raise cash through public or private issuance of debt or equity securities on favorable terms or at all. In the event of a successful issuance, existing equity holders would likely face substantial dilution.

Cash Generated from the Contribution of Existing Assets to Joint Ventures—

Although not currently planned or contemplated, in the long term we may seek to raise capital by contributing one or more of our existing assets to a joint venture with a third party. Investments in joint ventures are typically complicated and may, under certain circumstances, involve risks not present were a third party not involved. Our ability to successfully identify, negotiate and close joint venture transactions on acceptable terms or at all is highly uncertain in the current economic environment.

Proceeds from Additional Secured or Unsecured Debt Financings—

We do not currently have arrangements for any future secured debt financings and do not expect to obtain any secured debt financings in the near term that will generate net cash proceeds. We currently do not believe that we will be able to address challenges to our liquidity position (particularly debt maturities, leasing costs and capital expenditures) through future secured debt financings that generate net cash proceeds. However, we may seek to extend the maturity dates of certain secured debt financing encumbering our properties as they come due. Additionally, we do not believe that we will be able to obtain any significant unsecured debt financings on terms acceptable to us in the near future.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

Potential Uses of Liquidity—

The following are the projected uses, and some of the potential uses, of our cash in the near term. Because of the current uncertainty in the real estate market and the economy as a whole, there may be other uses of our cash that are unexpected (and that are not identified below).

Property Operations and Corporate Expenses—

Management is focused on a careful and efficient use of cash to fund property operating and corporate expenses. All of our business units underwent a thorough budgeting process in the fourth quarter of 2012 to allow for support of the Company’s 2013 business plan, while preserving unrestricted cash. Management continues to look for opportunities to reduce general and administrative expenses. Our completed and any future property dispositions may further reduce these expenses. Regardless of these efforts, operating our properties and business requires a significant amount of capital.

Capital Expenditures (Including Commissions and Tenant Improvements)—

Capital expenditures fluctuate in any given period, subject to the nature, extent and timing of improvements required to maintain our properties. Leasing costs also fluctuate in any given period, depending upon such factors as the type of property, the length of the lease, the type of lease, the involvement of external leasing agents and overall market conditions. Our costs for capital expenditures and leasing fall into two categories: (1) amounts that we are contractually obligated to spend and (2) discretionary amounts.

Contractual Obligations—

We have $15.2 million of restricted cash available to pay for leasing costs as of June 30, 2013. Other than at KPMG Tower, the leasing reserves at our LACBD properties have been exhausted in large part, and leasing costs will need to be funded primarily from property-generated cash flow. As of June 30, 2013, we had executed leases that contractually commit us to pay our tenants $35.0 million for leasing costs as follows: Wells Fargo Tower ($15.6 million); Gas Company Tower ($12.7 million); 777 Tower ($4.2 million); and KPMG Tower ($2.5 million). Of these amounts. $13.6 million is contractually due in 2014, $0.1 million in 2015, $0.1 million in 2016, $8.1 million in 2017 and $2.6 million thereafter. The remaining $10.5 million is contractually available for payment to tenants upon request during 2013, but actual payment is largely determined by the timing of requests from those tenants.

Discretionary Expenditures—

We may limit the amount of discretionary funds allocated to capital expenditures and leasing costs in the near or longer term. If this occurs, it may result in a decrease in the number of leases we execute (particularly new leases, which are generally more costly to us than renewals) and average rental rates. In addition, for leases that we do execute, we expect to pay standard tenant concessions.

15

MPG OFFICE TRUST, INC.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

At our LACBD properties, we incurred approximately $9 per square foot, $59 per square foot and $28 per square foot in leasing costs on leases executed during the six months ended June 30, 2013, and the years ended December 31, 2012 and 2011, respectively. Actual leasing costs incurred will fluctuate as described above.

Payments in Connection with Loans—

Debt Service. As of June 30, 2013, we had $1.7 billion of debt. Our substantial indebtedness requires us to use a material portion of our cash flow to service principal and interest on our debt, which limits the cash flow available for other business expenses and opportunities. During the six months ended June 30, 2013, we made debt service payments totaling $56.6 million. The lockbox and cash management arrangements contained in our loan agreements require that substantially all of the income generated by our special purpose property-owning subsidiaries be deposited directly into lockbox accounts and then swept into cash management accounts for the benefit of our lenders. Cash is distributed to us only after funding of improvement, leasing and maintenance reserves (as applicable) and the payment of debt service, insurance, taxes, operating expenses, and extraordinary capital expenditures and leasing expenses. In addition, excess operating cash flow from KPMG Tower is being swept by the lender to reduce the principal balance of the mortgage loan. During the six months ended June 30, 2013, the lender applied $7.2 million of the property’s excess operating cash flow to reduce the principal balance of the KPMG Tower mortgage loan.

Principal Payment Obligations. As our debt matures, our principal payment obligations present significant future cash requirements. We may not be able to successfully extend, refinance or repay our debt depending upon a number of factors, including property valuations, availability of credit, lending standards and economic conditions. We do not have any committed financing sources available to refinance our debt as it matures. For a further discussion of our debt’s effect on our financial condition and operating flexibility, see “Risk Factors” contained in this prospectus supplement and Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K filed with the SEC on March 18, 2013.

As of June 30, 2013, a summary of our debt maturing in 2013 is as follows (in millions):

KPMG Tower	$	357.8
777 Tower	273.0
Principal payable at maturity	$	630.8

Our KPMG Tower and 777 Tower mortgage loans mature on October 9, 2013 and November 1, 2013, respectively. We do not have a commitment from the lenders to extend the maturity dates of these loans. The loans may require a paydown upon extension or refinancing (depending on market conditions), funding of additional reserve amounts, or both. We may use cash on hand, including the net proceeds from the sale of Plaza Las Fuentes, to make any such payments. If we are unable or unwilling to use cash on hand to make such payments, we may face challenges in repaying, extending or refinancing these loans on favorable terms or at all, and we may be forced to give back the assets to the lenders.

MPG OFFICE TRUST, INC.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Payments to Extend, Refinance, Modify or Exit Loans. Upcoming debt maturities present cash obligations that the relevant special purpose property-owning subsidiary obligor may not be able to satisfy. For assets that we do not or cannot dispose of and for which the relevant special purpose property-owning subsidiary is unable or unwilling to fund the resulting obligations, we may seek to extend or refinance the applicable loans or may default upon such loans. Recently, extending or refinancing loans has required principal paydowns, the funding of additional reserve amounts and the payment of certain fees to, and expenses of, the applicable lenders. In addition, lenders may impose cash flow restrictions in connection with refinancings, such as cash flow sweeps and lockboxes. These fees and cash flow restrictions will affect our ability to fund our other uses. The terms of the extensions or refinancings may also include significantly restrictive operational and financial covenants. The default by the relevant special purpose property-owning subsidiary obligor upon any such loans could result in foreclosure of the property.

Payment of Potential Federal and State Income Tax Obligations—

As of December 31, 2012, we had $845 million of federal and $889 million of state net operating loss (“NOL”) carryforwards available to offset future taxable income. We used NOL carryforwards and other tax attributes to offset regular taxable income in 2012 and expect to continue to use them in future taxable years. Generally, a REIT that distributes earnings to its stockholders in an amount that equals or exceeds its taxable income is not subject to income taxes that would otherwise be taxed at a federal corporate tax rate of 35% and a California tax rate of 8.84%. In the absence of distributions to stockholders, NOL carryforwards may be utilized to offset REIT taxable income for federal and California income tax purposes.

Our ability to use NOL carryforwards in 2013 and future years could be negatively impacted by changes in ownership of the Company, as defined under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”) (which generally limits the amount of NOL carryforwards that may be used on an annual basis in post-change tax years), or by legislative action within the jurisdictions in which we own property. As of June 30, 2013, all of our properties are located within the State of California whose financial condition is among the most troubled of any state in the United States. Under prior California law, NOL carryforwards were suspended in 2002, 2003 and from 2008 through 2011 and could not be used to offset taxable income for California franchise tax purposes in such tax years. The State of California may introduce new legislation to suspend the utilization of NOL carryforwards in future tax years. If such an event were to occur, we may be subject to tax if a sufficient amount of earnings is not distributed to our stockholders. In that case, to the extent that the use of California NOL carryforwards is suspended, our California taxable income would be subject to the regular California corporate tax rate of 8.84% instead of the effective California alternative minimum tax (“AMT”) rate (after the utilization of NOL carryforwards) of 0.665%. In this event, the significant increase in our tax obligation to the State of California could impact potential dispositions of assets or other corporate events.

Entitlement-Related Costs—

We periodically evaluate the size, timing, costs and scope of our entitlement-related work and, as necessary, scale activity to reflect our financial position, overall economic conditions and the real estate fundamentals that exist in our submarkets. We expect to allocate a limited amount of cash towards pursuing and preserving entitlements during the near term.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Distributions to Common and Preferred Stockholders and Unit Holders—

We are required to distribute 90% of our REIT taxable income (excluding net capital gains) on an annual basis in order to qualify as a REIT for federal income tax purposes.

As of December 31, 2012, we had $845 million of federal NOL carryforwards, of which $715 million related to MPG Office Trust, Inc. and $130 million related to our taxable REIT subsidiary (“TRS”) entities. Due to our focus on preserving unrestricted cash and the availability of NOL carryforwards to offset future taxable income, we do not expect to pay distributions on our common stock and our 7.625% Series A Cumulative Redeemable Preferred Stock (the “Series A preferred stock”) in the foreseeable future. We do not expect the need to pay distributions to our stockholders during 2013 to maintain our REIT status due to the use of NOL carryforwards, as necessary. In determining REIT taxable income for purposes of applying the 90% distribution requirement, NOL carryforwards can be taken into account.

On December 19, 2008, our board of directors suspended the payment of dividends on our Series A preferred stock. Dividends on our Series A preferred stock are cumulative, and therefore, will continue to accrue at an annual rate of $1.9064 per share. As of July 31, 2013, we have missed 19 quarterly dividend payments. The amount of dividends in arrears totals $88.1 million.

All distributions to our common stockholders, preferred stockholders and Operating Partnership noncontrolling common unit holders are at the discretion of the board of directors. The actual amount and timing of distributions in 2013 and beyond, if any, will be at the discretion of our board of directors and will depend upon our financial condition in addition to the requirements of the Code, and no assurance can be given as to the amounts or timing of future distributions.

Indebtedness

As of June 30, 2013, our debt was comprised of mortgage and mezzanine loans secured by five properties. Our variable-rate debt bears interest at a rate based on one-month LIBOR, which was 0.19% as of June 30, 2013. A summary of our debt as of June 30, 2013 is as follows (in millions, except percentage and year amounts):

	Principal Amount			Percent of Total Debt		Effective Interest Rate		Weighted Average Term to Maturity

(1) On July 18, 2013, we sold Plaza Las Fuentes. As a result, the $32.7 million mortgage and $11.3 million mezzanine loans were repaid at closing using proceeds from the transaction.

As of June 30, 2013, our ratio of total debt to total consolidated market capitalization was 79.5% of our total market capitalization of $2.1 billion (based on the closing price of our common stock of $3.14 per share on the NYSE on June 28, 2013). Our ratio of total debt plus liquidation preference of the Series A preferred stock to total consolidated market capitalization was 91.2% as of June 30, 2013. Our total consolidated market capitalization includes the book value of our debt, the $25.00 liquidation preference of 9.7 million shares of Series A preferred stock and the market value of our outstanding common stock and noncontrolling common units of the Operating Partnership as of June 30, 2013.

Operating Partnership Contingent Obligations

Non-Recourse Carve Out Guarantees—

All of the Company’s $1.7 billion of mortgage and mezzanine debt is subject to “non-recourse carve out” guarantees that expire upon elimination of the underlying loan obligations. Under these guarantees, these otherwise non-recourse loans can become partially or fully recourse against the Operating Partnership if certain triggering events occur. Although these events differ from loan to loan, some of the common events include:

• The special purpose property-owning subsidiary’s or the Operating Partnership’s filing a voluntary petition for bankruptcy;

• The special purpose property-owning subsidiary’s failure to maintain its status as a special purpose entity;

• Subject to certain conditions, the special purpose property-owning subsidiary’s failure to obtain the lender’s written consent prior to any subordinate financing or other voluntary lien encumbering the associated property; and

• Subject to certain conditions, the special purpose property-owning subsidiary’s failure to obtain the lender’s written consent prior to a transfer or conveyance of the associated property, including, in some cases, indirect transfers in connection with a change in control of the Operating Partnership or the Company.

In addition, other items that are customarily recourse to a non-recourse carve out guarantor include, but are not limited to, the payment of real property taxes, the breach of representations related to environmental issues or hazardous substances, physical waste of the property, liens which are senior to the mortgage loan and outstanding security deposits.

As of June 30, 2013, to our knowledge the Company had not triggered any of the “non-recourse carve out” guarantees on its otherwise non-recourse loans. The maximum amount the Operating Partnership would be required to pay under a “non-recourse carve out” guarantee is the principal amount of the loan (or a total of $1.7 billion as of June 30, 2013 for all loans). This maximum amount does not include liabilities related to environmental issues or hazardous substances. Losses resulting from the breach of our loan agreement representations related to environmental issues or hazardous substances are generally recourse to the Operating Partnership pursuant to our “non-recourse carve out” guarantees and any such losses would be in addition to the total principal amounts of our loans. The potential losses are not quantifiable and can be material in certain circumstances, depending on the severity of the environmental or hazardous substance issues. Since each of our non-recourse loans is secured by the office building owned by the special purpose property-owning subsidiary, the amount due to the lender from the Operating Partnership in the event a “non-recourse carve out” guarantee is triggered could subsequently be partially or fully mitigated by the net proceeds received from any disposition of the office building; however, such proceeds may not be sufficient to cover the maximum potential amount due, depending on the particular asset.

MPG OFFICE TRUST, INC.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

In the event that any of these triggering events occur and the loans become partially or fully recourse against the Operating Partnership, our business, financial condition, results of operations and common stock price would be materially adversely affected and we could become insolvent.

Pursuant to the terms of certain of our mortgage loan agreements, we are required to report a debt service coverage ratio (“DSCR”) calculated using the formulas specified in the underlying loan agreements. We have submitted the required reports to the lenders for the measurement periods ended June 30, 2013. Under the Gas Company Tower mortgage loan, we reported a DSCR of 1.04 to 1.00, calculated using actual debt service under the loan, and a DSCR of 0.82 to 1.00, calculated using actual debt service plus a hypothetical principal payment using a 30-year amortization schedule. Because the reported DSCR using the actual debt service plus a hypothetical principal payment was less than 1.00 to 1.00, the lender could seek to remove the Company as property manager of Gas Company Tower.

Pursuant to the terms of the Gas Company Tower, KPMG Tower, Plaza Las Fuentes and Wells Fargo Tower mortgage loan agreements and the Plaza Las Fuentes mezzanine loan agreement, we are required to provide annual audited financial statements of MPG Office Trust, Inc. to the lenders or agents. The receipt of any opinion other than an “unqualified” audit opinion on our annual audited financial statements is an event of default under the loan agreements for the properties listed above. If an event of default occurs, the lenders have the right to pursue the remedies contained in the loan documents, including acceleration of all or a portion of the debt and foreclosure.

Management, Leasing and Development Services Revenue

Management, leasing and development services revenue decreased $0.6 million, or 100%, for the three months ended June 30, 2013 as compared to June 30, 2012, due to a reduction in leasing commissions earned from the joint venture. On December 21, 2012, we sold our remaining interest in the joint venture and therefore earned no revenue from the joint venture during 2013.

General and Administrative Expense

General and administrative expenses increased $6.9 million, or 111%, for the three months ended June 30, 2013 as compared to June 30, 2012, mainly due to increased professional services fees related to the merger with Brookfield and accrual of a lease takeover obligation related to a former tenant.

Other Expense

Other expense decreased $2.0 million, or 100%, for the three months ended June 30, 2013 as compared to June 30, 2012, primarily due to a payment in June 2012 of $2.0 million for a release of all claims under the guaranty of partial payment associated with the 3800 Chapman mortgage loan (a property that was disposed of during 2012).

Interest Expense

Interest expense decreased $4.1 million, or 16%, for the three months ended June 30, 2013 as compared to June 30, 2012, primarily due to the expiration of the KPMG Tower interest rate swap on August 9, 2012.

Discontinued Operations

Our income from discontinued operations of $112.0 million for the three months ended June 30, 2013 is comprised of a gain on sale of real estate totaling $111.9 million from the disposition of US Bank Tower and the Westlawn off-site parking garage. Our income from discontinued operations of $98.3 million for the three months ended June 30, 2012 is primarily comprised of a $102.5 million gain on settlement of debt recorded in connection with the disposition of Brea Corporate Place and Brea Financial Commons (together, the “Brea Campus”) and Stadium Towers Plaza and a $16.0 million gain on sale of real estate recorded in connection with the disposition of the Brea Campus, Stadium Towers Plaza and the City Tower development site.

Interest and Other Revenue

Interest and other revenue decreased $12.9 million, or 96%, for the six months ended June 30, 2013 as compared to June 30, 2012, primarily due to a termination payment received during 2012 from Beacon Capital related to the joint venture.

General and Administrative Expense

General and administrative expenses increased $7.2 million, or 61%, for the six months ended June 30, 2013 as compared to June 30, 2012, mainly due to increased professional services fees related to the merger with Brookfield and accrual of a lease takeover obligation related to a former tenant.

Equity in Net Income of Unconsolidated Joint Venture

Equity in net income of unconsolidated joint venture decreased $14.3 million for the six months ended June 30, 2013 as compared to June 30, 2012, due to recognition of our 20% share of the gain on sale of real estate of Wells Fargo Center – Denver and San Diego Tech Center by the joint venture in 2012, with no comparable activity during 2013.

Discontinued Operations

Our income from discontinued operations of $110.7 million for the six months ended June 30, 2013 is primarily comprised of a gain on sale of real estate totaling $111.9 million related to the disposition of the US Bank Tower and the Westlawn off-site parking garage. Our income from discontinued operations of $98.4 million for the six months ended June 30, 2012 is primarily comprised of a $115.6 million gain on settlement of debt recorded in connection with the disposition of the Brea Campus, Stadium Towers Plaza, 700 North Central and 801 North Brand and a $21.2 million gain on sale of real estate recorded in connection with the disposition of the Brea Campus, Stadium Towers Plaza, the City Tower development site, 700 North Central and 801 North Brand.

Cash Flow

The following summary discussion of our cash flow is based on the consolidated statements of cash flows contained in this prospectus supplement and is not meant to be an all-inclusive discussion of the changes in our cash flow for the periods presented below. The cash flow amounts shown below include the activities of discontinued operations.

	For the Six Months Ended						Increase/ (Decrease)
	June 30, 2013			June 30, 2012
	(In thousands)
Net cash (used in) provided by operating activities	$	(8,144	)	$	7,425		$	(15,569	)
Net cash provided by investing activities	365,311			41,519			323,792
Net cash used in financing activities	(267,611		)	(427		)	267,184

As discussed above, our business requires continued access to adequate cash to fund our liquidity needs. Over the last several years, we have maintained our liquidity position through secured debt financings, cash-generating asset sales and asset dispositions at or below the debt in cooperation with our lenders, as well as reductions in leasing costs, discretionary capital expenditures, property operating expenses, and general and administrative expenses. We are working to address challenges to our liquidity position, particularly debt maturities, leasing costs and capital expenditures. See “Liquidity and Capital Resources” above for a detailed discussion of our potential sources and uses of liquidity. In the event we are unable to meet our liquidity challenges, we could become insolvent.

Operating Activities

Our cash flow from operating activities is primarily dependent upon (1) the occupancy level of our portfolio, (2) the rental rates achieved on our leases, and (3) the collectability of rent and other amounts billed to our tenants and is also tied to our level of operating expenses and other general and administrative costs. Net cash used in operating activities during the six months ended June 30, 2013 totaled $8.1 million, compared to net cash provided by operating activities of $7.4 million during the six months ended June 30, 2012. A termination payment from Beacon Capital combined with cash received from the unconsolidated joint venture during 2012, with no comparable activity during 2013, were the primary drivers of the change in net cash (used in) provided by operating activities.

Investing Activities

Our cash flow from investing activities is generally impacted by the amount of capital expenditures for our office properties. Net cash provided by investing activities totaled $365.3 million during the six months ended June 30, 2013, compared to net cash provided by investing activities of $41.5 million during the six months ended June 30, 2012. Higher proceeds from the disposition of real estate during 2013 were the primary driver of the change in net cash provided by investing activities.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Financing Activities

Our cash flow from financing activities is generally impacted by our loan activity, less any dividends and distributions paid to our stockholders and noncontrolling common units of the Operating Partnership, if any. Net cash used in financing activities totaled $267.6 million during the six months ended June 30, 2013, compared to net cash used in financing activities of $0.4 million during the six months ended June 30, 2012. The repayment of the US Bank Tower mortgage loan upon disposition of the property and excess cash flow at KPMG Tower swept by the lender to reduce the principal balance of the mortgage loan were the primary drivers of the change in net cash used in financing activities. Due to our focus on preserving our unrestricted cash and the availability of NOL carryforwards to offset future taxable income, we do not expect to pay distributions on our common stock and Series A preferred stock in the foreseeable future.

Undeveloped Properties

We periodically evaluate the size, timing, costs and scope of our entitlement-related work and, as necessary, scale activity to reflect our financial position, overall economic conditions and the real estate fundamentals that exist in our submarkets. We expect to allocate a limited amount of cash towards pursuing and preserving entitlements during the near term.

Off-Balance Sheet Arrangements

We have certain off-balance sheet arrangements, which we believe are appropriately disclosed in this prospectus supplement, our Annual Report on Form 10-K filed with the SEC on March 18, 2013 and elsewhere. We do not believe that any of these off-balance sheet arrangements have or are reasonably likely to have a material effect on our financial condition, results of operations, liquidity or capital resources.

__________

(1) On July 18, 2013, we sold Plaza Las Fuentes. This property was classified as held for sale as of June 30, 2013. See “Subsequent Events.”

(2) Interest payments on our fixed-rate debt are calculated based on contractual interest rates and scheduled maturity dates.

(3) Interest payments on our variable-rate debt are calculated based on scheduled maturity dates and the one-month LIBOR rate of 0.19% as of June 28, 2013 plus the contractual spread per the loan agreement.

(4) Includes principal and interest payments.

(5) Includes operating lease obligations for subleased office space at 1733 Ocean. We have mitigated this obligation through sublease of that space to third-party tenants. The amounts expected to be mitigated through future sublease payments total $342 and $244 for the years ending December 31, 2013 and 2014, respectively.

(6) Tenant-related commitments include tenant improvements and leasing commissions and are based on executed leases as of June 30, 2013.

(7) Includes an air space lease for Plaza Las Fuentes. The air space rent is calculated through the lease expiration date in 2027. As discussed above, on July 18, 2013 we sold Plaza Las Fuentes and the air space lease was transferred to the buyer.

Litigation

General

We are involved in various litigation and other legal matters, including personal injury claims and administrative proceedings, which we are addressing or defending in the ordinary course of business. Management believes that any liability that may potentially result upon resolution of the matters that are currently pending will not have a material adverse effect on our business, financial condition or financial statements as a whole.

Merger-Related Litigation

Following the announcement of the execution of the Merger Agreement, seven putative class actions were filed against the Company, the members of the Company’s board of directors, the Operating Partnership, Brookfield, Sub REIT, REIT Merger Sub, Partnership Merger Sub and Brookfield DTLA Inc. Five of these lawsuits were filed on behalf of the Company’s common stockholders: (i) two lawsuits, captioned Coyne v. MPG Office Trust, Inc., et al., No. BC507342 (the “Coyne Action”), and Masih v. MPG Office Trust, Inc., et al., No. BC507962 (the “Masih Action”), were filed in the Superior Court of the State of California in Los Angeles County on April 29, 2013 and May 3, 2013, respectively; and (ii) three lawsuits, captioned Kim v. MPG Office Trust, Inc. et al., No. 24-C-13-002600 (the “Kim Action”), Perkins v. MPG Office Trust, Inc., et al., No. 24‑C-13-002778 (the “Perkins Action”) and Dell’Osso v. MPG Office Trust, Inc., et al., No. 24-C-13-003283 (the “Dell’Osso Action”) were filed in the Circuit Court for Baltimore City, Maryland on May 1, 2013, May 8, 2013 and May 22, 2013, respectively (collectively, the “Common Stock Actions”). Two lawsuits, captioned Cohen v. MPG Office Trust, Inc.et al., No. 24‑C-13-004097 (the “Cohen Action”) and Donlan v. Weinstein, et al., No. 24‑C-13-004293 (the “Donlan Action”), were filed on behalf of the Company’s preferred stockholders in the Circuit Court for Baltimore City, Maryland on June 20, 2013 and July 2, 2013, respectively (collectively, the “Preferred Stock Actions,” together with the Common Stock Actions, the “Merger Litigations”).

In each of the Common Stock Actions, the plaintiffs allege, among other things, that the Company’s board of directors breached their fiduciary duties in connection with the merger by failing to maximize the value of the Company and ignoring or failing to protect against conflicts of interest, and that the relevant Brookfield Parties named as defendants aided and abetted those breaches of fiduciary duty. The Kim Action further alleges that the Operating Partnership also aided and abetted the breaches of fiduciary duty by the Company’s board of directors, and the Dell’Osso Action further alleges that the Company and the Operating Partnership aided and abetted the breaches of fiduciary duty by the Company’s board of directors. On June 4, 2013, the Kim and Perkins plaintiffs filed identical, amended complaints in the Circuit Court for Baltimore City, Maryland. On June 5, 2013, the Masih plaintiffs also filed an amended complaint in the Superior Court of the State of California in Los Angeles County. The three amended complaints, as well as the Dell’Osso Action complaint, allege that the preliminary proxy statement filed by the Company with the SEC on May 21, 2013 is false and/or misleading because it fails to include certain details of the process leading up to the merger and fails to provide adequate information concerning the Company’s financial advisors.

30

MPG OFFICE TRUST, INC.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

In each of the Preferred Stock Actions, which were brought on behalf of Company’s preferred stockholders, the plaintiffs allege, among other things, that, by entering into the Merger Agreement and tender offer, the Company breached the Articles Supplementary, which governs the issuance of the Company Preferred Shares, that the Company’s board of directors breached their fiduciary duties by agreeing to a Merger Agreement that violated the preferred stockholders’ contractual rights and that the relevant Brookfield Parties named as defendants aided and abetted those breaches of contract and fiduciary duty. On July 15, 2013, the plaintiffs in the Preferred Stock Actions filed a joint amended complaint in the Circuit Court for Baltimore City, Maryland that further alleges that the Company’s board of directors failed to disclose material information regarding Brookfield’s extension of the tender offer. On that same day, an intervenor plaintiff, preferred stockholder EJF Debt Opportunities Master Fund, L.P., EJF Debt Opportunities Master Fund II, LP, and EJF Select Master Fund (collectively ‘‘EJF’’), filed a brief in support of the Cohen and Donlan plaintiffs’ motion for preliminary injunction, which included additional allegations that (i) the Company’s board of directors breached their fiduciary duties by entering into a transaction that favored the common stockholders and disfavored the preferred stockholders; and (ii) the disclosures filed by the Company and Brookfield are misleading because the new preferred shares will not have the same rights as the existing preferred shares because of the ability of other Brookfield subsidiaries to issue securities that will have an effective priority over the new preferred shares.

The plaintiffs in the seven lawsuits seek an injunction against the merger, rescission or rescissory damages in the event the merger has been consummated, an award of fees and costs, including attorneys’ and experts’ fees, and other relief.

By letter dated June 13, 2013, plaintiffs in the Kim, Perkins, and Dell’Osso actions jointly requested that the Circuit Court for Baltimore City, Maryland issue a stay of the cases in Maryland, pending the resolution of the Coyne Action and the Masih Action in California. On June 25, 2013, the Superior Court of the State of California in Los Angeles County ordered the Coyne Action and the Masih Action to be consolidated (the “Consolidated Common Stock Action”).

On July 10, 2013, solely to avoid the costs, risks and uncertainties inherent in litigation, the Company and the other named defendants in the Consolidated Common Stock Action signed a memorandum of understanding (the ‘‘MOU’’), regarding a proposed settlement of all claims asserted therein. The MOU provides, among other things, that the parties will seek to enter into a stipulation of settlement which provides for the release of all asserted claims. The asserted claims will not be released until such stipulation of settlement is approved by the court. There can be no assurance that the parties will ultimately enter into a stipulation of settlement or that the court will approve such settlement even if the parties were to enter into such stipulation. Additionally, as part of the MOU, the Company agreed (i) to make certain additional disclosures related to the merger, which were filed with the SEC on a Schedule 14A dated July 11, 2013, (ii) to amend the Merger Agreement to allow the Company to release third parties currently subject to confidentiality agreements with the Company from any standstill restrictions contained in such agreements and (iii) to file a Current Report on Form 8-K and related press release (which were respectively filed and issued on July 11, 2013). Finally, in connection with the proposed settlement, plaintiffs in the Consolidated Common Stock Action intend to seek, and the defendants have agreed to pay, an award of attorneys’ fees and expenses in an amount to be determined by the Superior Court of the State of California in Los Angeles County. This payment will not affect the amount of consideration to be received by the Company’s stockholders pursuant to the terms of the Merger Agreement.

MPG OFFICE TRUST, INC.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

In the Preferred Stock Actions, at a hearing on July 24, 2013, the Circuit Court for Baltimore City, Maryland denied plaintiffs’ motion for a preliminary injunction that sought to enjoin the tender offer and the merger.

Critical Accounting Policies

Please refer to our Annual Report on Form 10-K filed with the SEC on March 18, 2013 for a discussion of our critical accounting policies for “Impairment Evaluation” and “Revenue Recognition.” There have been no changes to these policies during the three months ended June 30, 2013.

New Accounting Pronouncements

There are no recently issued accounting pronouncements that are expected to have a material effect on our financial condition and results of operations in future periods.

Subsequent Events

Approval of Merger

On July 17, 2013, the Company’s common stockholders voted to approve the merger of the Company with REIT Merger Sub and the other transactions contemplated by the Merger Agreement. The Company expects the merger to close in the third quarter of 2013, following fulfillment of the conditions to closing, including receipt of required lender consents.

Sale of Plaza Las Fuentes

On July 18, 2013, we sold Plaza Las Fuentes to affiliates of East West Bank and Downtown Properties Holdings, LLC. The purchase price was $75.0 million. Net proceeds from the transaction were approximately $30 million, which may potentially be used to make loan re-balancing payments on our upcoming 2013 debt maturities at KPMG Tower and 777 Tower. The $32.7 million mortgage and $11.3 million mezzanine loan balances were repaid at closing using proceeds from the transaction.

Merger-Related Litigation

Following the announcement of the execution of the Merger Agreement, seven putative class actions were filed against the Company, the members of the Company’s board of directors, the Operating Partnership, Brookfield, Sub REIT, REIT Merger Sub, Partnership Merger Sub and Brookfield DTLA Inc. Five of these lawsuits were filed on behalf of the Company’s common stockholders: (i) two lawsuits, captioned Coyne v. MPG Office Trust, Inc., et al., No. BC507342 (the “Coyne Action”), and Masih v. MPG Office Trust, Inc., et al., No. BC507962 (the “Masih Action”), were filed in the Superior Court of the State of California in Los Angeles County on April 29, 2013 and May 3, 2013, respectively; and (ii) three lawsuits, captioned Kim v. MPG Office Trust, Inc. et al., No. 24-C-13-002600 (the “Kim Action”), Perkins v. MPG Office Trust, Inc., et al., No. 24‑C-13-002778 (the “Perkins Action”) and Dell’Osso v.

respectively (collectively, the “Common Stock Actions”). Two lawsuits, captioned Cohen v. MPG Office Trust, Inc.et al., No. 24‑C-13-004097 (the “Cohen Action”) and Donlan v. Weinstein, et al., No. 24‑C-13-004293 (the “Donlan Action”), were filed on behalf of the Company’s preferred stockholders in the Circuit Court for Baltimore City, Maryland on June 20, 2013 and July 2, 2013, respectively (collectively, the “Preferred Stock Actions,” together with the Common Stock Actions, the “Merger Litigations”).

In each of the Common Stock Actions, the plaintiffs allege, among other things, that the Company’s board of directors breached their fiduciary duties in connection with the merger by failing to maximize the value of the Company and ignoring or failing to protect against conflicts of interest, and that the relevant Brookfield Parties named as defendants aided and abetted those breaches of fiduciary duty. The Kim Action further alleges that the Operating Partnership also aided and abetted the breaches of fiduciary duty by the Company’s board of directors, and the Dell’Osso Action further alleges that the Company and the Operating Partnership aided and abetted the breaches of fiduciary duty by the Company’s board of directors. On June 4, 2013, the Kim and Perkins plaintiffs filed identical, amended complaints in the Circuit Court for Baltimore City, Maryland. On June 5, 2013, the Masih plaintiffs also filed an amended complaint in the Superior Court of the State of California in Los Angeles County. The three amended complaints, as well as the Dell’Osso Action complaint, allege that the preliminary proxy statement filed by the Company with the SEC on May 21, 2013 is false and/or misleading because it fails to include certain details of the process leading up to the merger and fails to provide adequate information concerning the Company’s financial advisors.

In each of the Preferred Stock Actions, which were brought on behalf of Company’s preferred stockholders, the plaintiffs allege, among other things, that, by entering into the Merger Agreement and tender offer, the Company breached the Articles Supplementary, which governs the issuance of the Series A preferred stock, that the Company’s board of directors breached their fiduciary duties by agreeing to a Merger Agreement that violated the preferred stockholders’ contractual rights and that the relevant Brookfield Parties named as defendants aided and abetted those breaches of contract and fiduciary duty. On July 15, 2013, the plaintiffs in the Preferred Stock Actions filed a joint amended complaint in the Circuit Court for Baltimore City, Maryland that further alleges that the Company’s board of directors failed to disclose material information regarding Brookfield’s extension of the tender offer. On that same day, an intervenor plaintiff, preferred stockholder EJF Debt Opportunities Master Fund, L.P., EJF Debt Opportunities Master Fund II, LP, and EJF Select Master Fund (collectively ‘‘EJF’’), filed a brief in support of the Cohen and Donlan plaintiffs’ motion for preliminary injunction, which included additional allegations that (i) the Company’s board of directors breached their fiduciary duties by entering into a transaction that favored the common stockholders and disfavored the preferred stockholders; and (ii) the disclosures filed by the Company and Brookfield are misleading because the new preferred shares will not have the same rights as the existing preferred shares because of the ability of other Brookfield subsidiaries to issue securities that will have an effective priority over the new preferred shares.

The plaintiffs in the seven lawsuits seek an injunction against the merger, rescission or rescissory damages in the event the merger has been consummated, an award of fees and costs, including attorneys’ and experts’ fees, and other relief.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

By letter dated June 13, 2013, plaintiffs in the Kim, Perkins, and Dell’Osso actions jointly requested that the Circuit Court for Baltimore City, Maryland issue a stay of the cases in Maryland, pending the resolution of the Coyne Action and the Masih Action in California. On June 25, 2013, the Superior Court of the State of California in Los Angeles County ordered the Coyne Action and the Masih Action to be consolidated (the “Consolidated Common Stock Action”).

On July 10, 2013, solely to avoid the costs, risks and uncertainties inherent in litigation, the Company and the other named defendants in the Consolidated Common Stock Action signed a memorandum of understanding (the ‘‘MOU’’), regarding a proposed settlement of all claims asserted therein. The MOU provides, among other things, that the parties will seek to enter into a stipulation of settlement which provides for the release of all asserted claims. The asserted claims will not be released until such stipulation of settlement is approved by the court. There can be no assurance that the parties will ultimately enter into a stipulation of settlement or that the court will approve such settlement even if the parties were to enter into such stipulation. Additionally, as part of the MOU, the Company agreed (i) to make certain additional disclosures related to the merger, which were filed with the SEC on a Schedule 14A dated July 11, 2013, (ii) to amend the Merger Agreement to allow the Company to release third parties currently subject to confidentiality agreements with the Company from any standstill restrictions contained in such agreements and (iii) to file a Current Report on Form 8-K and related press release (which were respectively filed and issued on July 11, 2013). Finally, in connection with the proposed settlement, plaintiffs in the Consolidated Common Stock Action intend to seek, and the defendants have agreed to pay, an award of attorneys’ fees and expenses in an amount to be determined by the Superior Court of the State of California in Los Angeles County. This payment will not affect the amount of consideration to be received by the Company’s stockholders pursuant to the terms of the Merger Agreement.

In the Preferred Stock Actions, at a hearing on July 24, 2013, the Circuit Court for Baltimore City, Maryland denied plaintiffs’ motion for a preliminary injunction that sought to enjoin the tender offer and the merger.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Non-GAAP Supplemental Measure

Funds from operations (“FFO”) is a widely recognized measure of REIT performance. We calculate FFO in accordance with the White Paper on FFO approved by the Board of Governors of the National Association of Real Estate Investment Trusts (“NAREIT”). The White Paper defines FFO as net income or loss (as computed in accordance with GAAP), excluding extraordinary items (as defined by GAAP), gains from disposition of depreciable real estate and impairment writedowns of depreciable real estate, plus real estate-related depreciation and amortization (including capitalized leasing costs and tenant allowances or improvements). Adjustments for the unconsolidated joint venture were calculated to reflect FFO on the same basis.

Management uses FFO as a supplemental performance measure because, in excluding real estate‑related depreciation and amortization, impairment writedowns of depreciable real estate and gains from disposition of depreciable real estate, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. We also believe that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare our operating performance with that of other REITs.

However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our results from operations, the utility of FFO as a measure of our performance is limited. Other Equity REITs may not calculate FFO in accordance with the NAREIT White Paper and, accordingly, our FFO may not be comparable to such other Equity REITs’ FFO. As a result, FFO should be considered only as a supplement to net income or loss as a measure of our performance. FFO should not be used as a measure of our liquidity, nor is it indicative of funds available to meet our cash needs, including our ability to pay dividends or make distributions. FFO also should not be used as a supplement to or substitute for cash flow from operating activities (as computed in accordance with GAAP).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1—Organization and Description of Business

As used in these consolidated financial statements and related notes, the terms “MPG Office Trust,” the “Company,” “us,” “we” and “our” refer to MPG Office Trust, Inc. We are a self‑administered and self-managed real estate investment trust (“REIT”), and we operate as a REIT for federal income tax purposes. We are the largest owner and operator of Class A office properties in the Los Angeles Central Business District (“LACBD”).

Through our controlling interest in MPG Office, L.P. (the “Operating Partnership”), of which we are the sole general partner and hold an approximate 99.96% interest, and the subsidiaries of the Operating Partnership, including MPG Office Trust Services, Inc. and its subsidiaries (collectively known as the “Services Company”), we own, manage and lease real estate located primarily in the greater Los Angeles area of California. This real estate primarily consists of office properties, parking garages and land parcels.

As of June 30, 2013, the Operating Partnership indirectly owns five office properties and on- and off-site parking garages (the “Total Portfolio”). We hold an approximate 99.96% interest in the Operating Partnership, and therefore do not completely own the Total Portfolio. The aggregate square footage of the Total Portfolio has not been reduced to reflect our limited partners’ 0.04% share of the Operating Partnership.

As of June 30, 2013, the Total Portfolio included the following:

• Four office properties located in the LACBD totaling 5.0 million square feet that were 84.8% leased;

• One office property located in Pasadena, California totaling 0.2 million square feet that was 100.0% leased; and

• Parking garages located in the LACBD totaling 2.0 million square feet, which accommodate 6,496 vehicles.

We directly manage the properties in the Total Portfolio through the Operating Partnership and/or the Services Company. We receive income primarily from rental revenue (including tenant reimbursements) from our office properties, and to a lesser extent, from our parking garages.

On April 24, 2013, the Company and the Operating Partnership entered into a definitive merger agreement pursuant to which a newly formed fund controlled by Brookfield Office Properties Inc. (“Brookfield”) agreed to acquire the Company. The merger transaction was approved by the Company’s common stockholders on July 17, 2013. At the closing of the transaction, the Company’s common stockholders will receive merger consideration of $3.15 in cash per share, without interest and less any required withholding tax. The Company expects the merger to close in the third quarter of 2013, following fulfillment of the conditions to closing, including receipt of required lender consents. See Note 3 “Merger with Brookfield.”

Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with such rules and regulations. In the opinion of management, all adjustments, consisting of only those of a normal and recurring nature, considered necessary for a fair presentation of the financial position and interim results of MPG Office Trust, Inc., the Operating Partnership and the subsidiaries of the Operating Partnership as of and for the periods presented have been included. Our results of operations for interim periods are not necessarily indicative of those that may be expected for a full fiscal year.

Effective December 31, 2012, we adopted the provisions of Accounting Standards Update No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires an entity to present information about reclassification adjustments from accumulated other comprehensive income in their annual financial statements in a single note or on the face of the financial statements. We elected to present this information as a single note to the financial statements. See Note 9 “Accumulated Other Comprehensive Income.” The adoption had no impact on our previously reported earnings or earnings per share.

We classify properties as held for sale when certain criteria set forth in the Long-Lived Assets Classified as Held for Sale Subsections of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (the “FASB Codification”) Topic 360, Property, Plant, and Equipment, are met. At that time, we present the assets and liabilities of the property held for sale separately in the consolidated balance sheet. We cease recording depreciation and amortization expense at the time a property is classified as held for sale. Properties held for sale are reported at the lower of their carrying amount or their estimated fair value, less estimated costs to sell.

As of June 30, 2013, Plaza Las Fuentes is classified as held for sale. As of December 31, 2012, none of our properties were classified as held for sale. See Note 12 “Dispositions, Discontinued Operations and Assets Held for Sale.”

Certain amounts in the consolidated statements of operations for prior periods have been reclassified to reflect the activity of discontinued operations. Additionally, we reclassified (i) deferred rents to rents, deferred rents and other receivables, net; (ii) deferred leasing costs, the value of in-place leases, net and deferred loan costs, net to deferred charges, net; and (iii) acquired below market leases, net to accounts payable and other liabilities to conform to the 2013 presentation.

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could ultimately differ from such estimates.

The balance sheet data as of December 31, 2012 has been derived from our audited financial statements; however, the accompanying notes to the consolidated financial statements do not include all disclosures required by GAAP.

The financial information included herein should be read in conjunction with the consolidated financial statements and related notes included in our Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (“SEC”) on March 18, 2013 (the “2012 Form 10-K”) and our Current Report on Form 8-K filed with the SEC on June 12, 2013, which restated Part II, Item 8. “Financial Statements and Supplementary Data” of the 2012 Form 10-K to reflect the reclassification of the results of operations of US Bank Tower and the Westlawn off-site parking garage to discontinued operations.

Note 3—Merger with Brookfield

Merger Agreement

On April 24, 2013, the Company and the Operating Partnership entered into a definitive merger agreement (the “Merger Agreement”) pursuant to which a newly formed fund, Brookfield DTLA Holdings L.P., a Delaware limited partnership (which was subsequently converted into a Delaware limited liability company on May 10, 2013) (“Brookfield DTLA”), controlled by Brookfield agreed to acquire the Company. The Company will merge with and into Brookfield DTLA Fund Office Trust Inc., a Maryland corporation (“REIT Merger Sub”), with REIT Merger Sub surviving the merger. Brookfield DTLA will have the option, in its sole discretion and without requiring further consent, to request that the Company agree to change the direction of the merger so that the Company is the surviving entity. The Merger Agreement also provides for a merger of Brookfield DTLA Fund Properties LLC, a Maryland limited liability company (“Partnership Merger Sub”), with and into the Operating Partnership, with the Operating Partnership surviving the merger.

On July 17, 2013, the Company’s common stockholders voted to approve the merger of the Company with REIT Merger Sub and the other transactions contemplated by the Merger Agreement (collectively, the “merger”). The Company expects the merger to close in the third quarter of 2013, following fulfillment of the conditions to closing, including receipt of required lender consents.

Under the terms of the Merger Agreement, each issued and outstanding share of our common stock will be automatically converted into, and canceled in exchange for, the right to receive $3.15 in cash, without interest and less any required withholding tax, (the “merger consideration”) at the closing of the merger. Each issued and outstanding share of restricted common stock will cease to be subject to forfeiture and will be canceled in exchange for the right to receive the merger consideration. Each issued and outstanding restricted stock unit will receive the merger consideration per share for each outstanding restricted stock unit. Each Company stock option granted under a Company plan, whether or not then exercisable, will be canceled in exchange for the right to receive the excess, if any, of the merger consideration over the exercise price per share of such Company stock option. If the exercise price per share of any such Company stock option is equal to or greater than the merger consideration, such Company stock option will be canceled without payment.

Additionally, a subsidiary of Brookfield has commenced a tender offer to purchase, subject to certain conditions, all of the Company’s outstanding 7.625% Series A Cumulative Redeemable Preferred Stock, par value $0.01 per share (the “Company Preferred Shares”), for $25.00 per share in cash, without interest. Any Company Preferred Shares that are not tendered will be converted in the merger into new

(Unaudited)

preferred shares of Brookfield DTLA Fund Office Trust Investor Inc., a Maryland corporation (“Sub REIT”), with rights, terms and conditions substantially identical to the rights, terms and conditions of the Company Preferred Shares.

In connection with the Merger Agreement, Brookfield has entered into a guarantee with respect to the obligations of its affiliates under the Merger Agreement, including the full performance and payment of all of the payment and/or monetary obligations and liabilities arising under or in connection with the Merger Agreement and the transactions contemplated thereby.

The Company and Brookfield DTLA have made certain customary representations, warranties and covenants in the Merger Agreement. The Company, among other things, subject to certain exceptions, covenanted: (i) to conduct its business in the ordinary course consistent with past practice during the interim period between the execution of the Merger Agreement and the consummation of the merger; and (ii) to not solicit, initiate or facilitate the making, submission or announcement of any acquisition proposal, or any proposal or offer that would reasonably be expected to lead to an acquisition proposal, or provide confidential information in connection with, any acquisition proposal.

The Merger Agreement contains certain termination rights for both the Company and Brookfield DTLA, including, among other bases for termination and subject to certain exceptions, if the merger has not been consummated on or before August 15, 2013, subject to (i) the Company’s right to an extension until September 16, 2013 and Brookfield DTLA’s right to extension until August 30, 2013, in each case if all the conditions to the closing, other than obtaining certain lender consents, have been satisfied or waived prior to August 15, 2013 and (ii) certain other extension rights further discussed below under “—Waiver and First Amendment to Merger Agreement.”

Waiver and First Amendment to Merger Agreement

On May 19, 2013, the Company, the Operating Partnership, Brookfield DTLA, Sub REIT, REIT Merger Sub and Partnership Merger Sub (Brookfield DTLA, Sub REIT, REIT Merger Sub and Partnership Merger Sub, collectively, the “Brookfield Parties”), entered into a waiver and first amendment to the Merger Agreement (the “Waiver and Amendment”).

Pursuant to the Waiver and Amendment, Brookfield DTLA has irrevocably waived its right to cash out non-tendered Company Preferred Shares. Accordingly, all Company Preferred Shares that are not validly tendered and accepted for payment in the tender offer will be converted into shares of 7.625% Series A Cumulative Redeemable Preferred Stock, par value $0.01 per share, of Sub REIT (collectively, the “Sub REIT Preferred Shares”), with rights, terms and conditions substantially identical to the rights, terms and conditions of the Company Preferred Shares.

The Waiver and Amendment also permits Brookfield DTLA to make amendments to the limited partnership agreement of the Operating Partnership in order to effectuate the provisions of the Merger Agreement relating to the potential investment in the Operating Partnership by DTLA Fund Holding Co., the conversion of general partner common units of the Operating Partnership into general partner common units of the Surviving Partnership, and the conversion of limited partner common units held by any subsidiary of the Company into Series B Partnership General Partner Units.

The Waiver and Amendment also clarifies that the tender offer Purchaser (as defined in the Merger Agreement) will not consummate the tender offer except immediately prior to the effective time of the merger unless both the Company and the tender offer Purchaser agree in writing.

In addition, the Waiver and Amendment reflects certain changes relating to a registration statement on Form S-4 (the “Form S-4”) that Sub REIT filed with the U.S. Securities and Exchange Commission (“SEC”) in connection with the potential issuance of Sub REIT Preferred Shares to the holders of Company Preferred Shares. The Waiver and Amendment clarifies that, in the absence of an SEC stop order that is then in effect, the effectiveness of the Form S-4 is not a condition to the Brookfield Parties’ obligations to consummate the merger. However, if all the conditions to the obligations of the Brookfield Parties to consummate the merger have been satisfied (other than those required to be satisfied or waived at the closing of the merger) but either (i) the Form S-4 has not become effective or (ii) the SEC has issued a stop order that is in effect, then Brookfield DTLA will have the right to delay the closing until the earliest to occur of (A) the date specified by Brookfield DTLA in the written notice exercising this right, (B) one business day after the effectiveness of the Form S-4, (C) one business day after any stop order issued in respect of the Form S-4 has been lifted, reversed or otherwise terminated, and (D) September 25, 2013. If Brookfield DTLA exercises this right, (X) Brookfield DTLA will be deemed to have immediately and irrevocably waived all of the conditions to its obligations to close the merger, other than the conditions relating to the following: (1) the absence of a legal restraint prohibiting the consummation of the merger to the extent not related to a stop order suspending the effectiveness of the Form S-4, (2) performance by the Company and the Operating Partnership of their agreements and covenants under the Merger Agreement, but only if such failure to perform constitutes a willful and material breach of the Merger Agreement that results in a long-term adverse effect on the business of the Company and the Operating Partnership (a “willful and material breach”), and (3) the absence of a Material Adverse Effect (as defined in the Merger Agreement); and (Y) after August 15, 2013, Brookfield DTLA will be deemed to have irrevocably waived all conditions to its obligations to close the merger except for the condition related to the performance by the Company and the Operating Partnership of their agreements and covenants under the Merger Agreement, but only if such failure to perform constitutes a willful and material breach of the Merger Agreement.

The Waiver and Amendment further provides that if either the Form S-4 has not become effective or the SEC has issued a stop order suspending the effectiveness of the Form S-4, the Company may extend the Outside Date (as defined in the Merger Agreement) up to until October 31, 2013. Additionally, if Brookfield DTLA elects to exercise its right to delay the closing as discussed above, then (i) on or prior to August 15, 2013, Brookfield DTLA’s right to terminate the Merger Agreement due to the failure of the merger to be consummated by the Outside Date will be limited to situations where there is a legal restraint prohibiting the consummation of the merger (other than to the extent related to a stop order suspending the effectiveness of the Form S-4) or there is a Material Adverse Effect, and (ii) after August 15, 2013, Brookfield DTLA will be deemed to have waived irrevocably any right to terminate the Merger Agreement due to the failure of the merger to be consummated by the Outside Date.

On July 10, 2013, the Company, the Operating Partnership and the Brookfield Parties entered into a second amendment to the Merger Agreement to permit the Company to release third parties that were then subject to confidentiality agreements with the Company from any standstill or similar provision contained in such agreements.

Merger-Related Litigation

See Note 15 “Subsequent Events.”

Note 4—Liquidity

Our business requires continued access to adequate cash to fund our liquidity needs. Over the last several years, we have maintained our liquidity position through secured debt financings, cash-generating asset sales and asset dispositions at or below the debt in cooperation with our lenders, as well as reductions in leasing costs, discretionary capital expenditures, property operating expenses, and general and administrative expenses.

The following are our potential sources of liquidity:

• Unrestricted and restricted cash;

• Cash generated from operations;

• Asset dispositions;

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

• Cash generated from the contribution of existing assets to joint ventures; and/or

• Proceeds from additional secured or unsecured debt financings.

We are working to address challenges to our liquidity position, particularly debt maturities, leasing costs and capital expenditures. We do not currently have committed sources of cash adequate to fund all of our potential needs, including our 2013 debt maturities. If we are unable to raise additional capital or sell assets, we may face challenges in repaying, extending or refinancing our existing debt (including our debt maturities) on favorable terms or at all, and we may be forced to give back assets to the relevant mortgage lenders. While we believe that access to future sources of significant cash will be challenging, we believe that we will have access to some of the liquidity sources identified above and that those sources will be sufficient to meet our near-term liquidity needs. On June 18, 2013, we sold US Bank Tower and the Westlawn off-site parking garage and received net proceeds of $103.0 million, a portion of which may potentially be used to make loan re-balancing payments on our upcoming 2013 debt maturities at KPMG Tower and 777 Tower. Additionally, on July 18, 2013, we sold Plaza Las Fuentes and received net proceeds of approximately $30 million, which may potentially be used to make loan re‑balancing payments on our upcoming 2013 debt maturities at KPMG Tower and 777 Tower. See Note 15 “Subsequent Events.”

Future sources of significant cash are essential to our liquidity and financial position, and if we are unable to generate adequate cash from these sources we will have liquidity-related problems and will be exposed to material risks. In addition, our inability to secure adequate sources of liquidity could lead to our eventual insolvency.

Potential Sources of Liquidity—

Asset Dispositions—

During the past several years, we have systematically disposed of assets in order to (1) preserve cash through the disposition of properties with current or projected negative cash flow and/or other potential near-term cash outlay requirements (including debt maturities) and (2) generate cash through the disposition of strategically-identified non-core properties with positive equity value. We may dispose of additional assets in the future in order to generate cash. However, we have a limited number of assets remaining that could be sold to generate net cash proceeds. If we choose to pursue such a disposition, we cannot assure you that such a disposition could be completed in a timely manner or on terms acceptable to us.

On June 18, 2013, we sold US Bank Tower and the Westlawn off-site parking garage and received net proceeds of $103.0 million, a portion of which may potentially be used to make loan re‑balancing payments on our upcoming 2013 debt maturities at KPMG Tower and 777 Tower.

On July 18, 2013, we sold Plaza Las Fuentes and received net proceeds of approximately $30 million, which may potentially be used to make loan re-balancing payments on our upcoming 2013 debt maturities at KPMG Tower and 777 Tower. See Note 15 “Subsequent Events.”

Proceeds from Additional Secured or Unsecured Debt Financings—

We do not currently have arrangements for any future secured debt financings and do not expect to obtain any secured debt financings in the near term that will generate net cash proceeds. We currently do not believe that we will be able to address challenges to our liquidity position (particularly debt maturities, leasing costs and capital expenditures) through future secured debt financings that generate net cash proceeds. However, we may seek to extend the maturity dates of certain secured debt financing encumbering our properties as they come due. Additionally, we do not believe that we will be able to obtain any significant unsecured debt financings on terms acceptable to us in the near future.

Potential Uses of Liquidity—

The following are the significant potential uses of our cash in the near term:

Payments in Connection with Loans—

Debt Service. As of June 30, 2013, we had $1.7 billion of debt. Our substantial indebtedness requires us to use a material portion of our cash flow to service principal and interest on our debt, which limits the cash flow available for other business expenses and opportunities. During the six months ended June 30, 2013, we made debt service payments totaling $56.6 million. The lockbox and cash management arrangements contained in our loan agreements require that substantially all of the income generated by our special purpose property-owning subsidiaries be deposited directly into lockbox accounts and then swept into cash management accounts for the benefit of our lenders. Cash is distributed to us only after funding of improvement, leasing and maintenance reserves (as applicable) and

F-13

MPG OFFICE TRUST, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

(Unaudited)

the payment of debt service, insurance, taxes, operating expenses, and extraordinary capital expenditures and leasing expenses. In addition, excess operating cash flow from KPMG Tower is being swept by the lender to reduce the principal balance of the mortgage loan. During the six months ended June 30, 2013, the lender applied $7.2 million of the property’s excess operating cash flow to reduce the principal balance of the KPMG Tower mortgage loan.

Principal Payment Obligations. As our debt matures, our principal payment obligations present significant future cash requirements. We may not be able to successfully extend, refinance or repay our debt depending upon a number of factors, including property valuations, availability of credit, lending standards and economic conditions. We do not have any committed financing sources available to refinance our debt as it matures.

As of June 30, 2013, a summary of our debt maturing in 2013 is as follows (in millions):

KPMG Tower	$	357.8
777 Tower	273.0
Principal payable at maturity	$	630.8

Our KPMG Tower and 777 Tower mortgage loans mature on October 9, 2013 and November 1, 2013, respectively. We do not have a commitment from the lenders to extend the maturity dates of these loans. The loans may require a paydown upon extension or refinancing (depending on market conditions), funding of additional reserve amounts, or both. We may use cash on hand, including the net proceeds from the sale of Plaza Las Fuentes, to make any such payments. If we are unable or unwilling to use cash on hand to make such payments, we may face challenges in repaying, extending or refinancing these loans on favorable terms or at all, and we may be forced to give back the assets to the lenders.

Payments to Extend, Refinance, Modify or Exit Loans. Upcoming debt maturities present cash obligations that the relevant special purpose property-owning subsidiary obligor may not be able to satisfy. For assets that we do not or cannot dispose of and for which the relevant special purpose property-owning subsidiary is unable or unwilling to fund the resulting obligations, we may seek to extend or refinance the applicable loans or may default upon such loans. Recently, extending or refinancing loans has required principal paydowns, the funding of additional reserve amounts and the payment of certain fees to, and expenses of, the applicable lenders. In addition, lenders may impose cash flow restrictions in connection with refinancings, such as cash flow sweeps and lockboxes. These fees and cash flow restrictions will affect our ability to fund our other uses. The terms of the extensions or refinancings may also include significantly restrictive operational and financial covenants. The default by the relevant special purpose property-owning subsidiary obligor upon any such loans could result in foreclosure of the property.

Rents, deferred rents and other receivables are presented net of an allowance for doubtful accounts of $1.1 million and $0.8 million as of June 30, 2013 and December 31, 2012, respectively. For the six months ended June 30, 2013 and 2012, we recorded a provision for doubtful accounts of $0.2 million and $1.1 million, respectively.

Note 6—Investment in Unconsolidated Joint Venture

On March 30, 2012, the Company, together with Charter Hall Office REIT (“Charter Hall”), sold its interests in Wells Fargo Center – Denver and San Diego Tech Center (both joint venture properties in which we owned a 20% interest) to affiliates of Beacon Capital Partners, LLC (“Beacon Capital”). Subsequent to the property dispositions, Charter Hall sold its 80% interest in the joint venture to an affiliate of Beacon Capital. We received net proceeds from these transactions totaling $25.9 million.

We received a $6.0 million payment from Beacon Capital in consideration for terminating our right to receive certain fees from the joint venture following the closing date of the transactions. We deferred recognition of $1.0 million of the consideration received during the six months ended June 30, 2012, representing prepaid revenue for the property management services and recorded $5.0 million of the consideration received as part of other income in the consolidated statement of operations.

Additionally, as a result of the disposition of the two properties noted above, during the six months ended June 30, 2012 we recorded $5.0 million as part of other income in the consolidated statement of operations to accelerate the difference between the carrying amount of the investment in the consolidated balance sheet and the underlying equity in those assets.

On December 21, 2012, we sold our 20% interest in the joint venture to an affiliate of Beacon Capital. We no longer have an ownership interest in the joint venture. During the three and six months ended June 30, 2012, we earned $0.4 million and $1.5 million, respectively, of revenue from the joint venture, which was recorded as part of management, leasing and development services in the consolidated statement of operations.

Operating Partnership Contingent Obligations

Non-Recourse Carve Out Guarantees—

All of the Company’s $1.7 billion of mortgage and mezzanine debt is subject to “non-recourse carve out” guarantees that expire upon elimination of the underlying loan obligations. Under these guarantees, these otherwise non-recourse loans can become partially or fully recourse against the Operating Partnership if certain triggering events occur. Although these events differ from loan to loan, some of the common events include:

• The special purpose property-owning subsidiary’s or the Operating Partnership’s filing a voluntary petition for bankruptcy;

• The special purpose property-owning subsidiary’s failure to maintain its status as a special purpose entity;

• Subject to certain conditions, the special purpose property-owning subsidiary’s failure to obtain the lender’s written consent prior to any subordinate financing or other voluntary lien encumbering the associated property; and

• Subject to certain conditions, the special purpose property-owning subsidiary’s failure to obtain the lender’s written consent prior to a transfer or conveyance of the associated property, including, in some cases, indirect transfers in connection with a change in control of the Operating Partnership or the Company.

In addition, other items that are customarily recourse to a non-recourse carve out guarantor include, but are not limited to, the payment of real property taxes, the breach of representations related to environmental issues or hazardous substances, physical waste of the property, liens which are senior to the mortgage loan and outstanding security deposits.

As of June 30, 2013, to our knowledge the Company had not triggered any of the “non-recourse carve out” guarantees on its otherwise non-recourse loans. The maximum amount the Operating Partnership would be required to pay under a “non-recourse carve out” guarantee is the principal amount of the loan (or a total of $1.7 billion as of June 30, 2013 for all loans). This maximum amount does not include liabilities related to environmental issues or hazardous substances. Losses resulting from the breach of our loan agreement representations related to environmental issues or hazardous substances are generally recourse to the Operating Partnership pursuant to our “non-recourse carve out” guarantees and any such losses would be in addition to the total principal amounts of our loans. The potential losses are not quantifiable and can be material in certain circumstances, depending on the severity of the environmental or hazardous substance issues. Since each of our non-recourse loans is secured by the office building owned by the special purpose property-owning subsidiary, the amount due to the lender from the Operating Partnership in the event a “non-recourse carve out” guarantee is triggered could subsequently be partially or fully mitigated by the net proceeds received from any disposition of the office building; however, such proceeds may not be sufficient to cover the maximum potential amount due, depending on the particular asset.

On January 30, 2013, we issued 35,000 shares of common stock to Thomas MPG Holding, LLC in exchange for 35,000 noncontrolling common units redeemed by the limited partner. We received no cash or other consideration for the noncontrolling common units redeemed.

On June 27, 2013, we issued 110,000 shares of common stock to Robert F. Maguire III and related entities in exchange for 110,000 noncontrolling common units redeemed by the limited partners. We received no cash or other consideration for the noncontrolling common units redeemed.

The following table sets forth the number of noncontrolling common units of the Operating Partnership outstanding and the aggregate redemption value of those units based on the closing market price of our common stock on the New York Stock Exchange (“NYSE”) as well as the ownership interest of those units in the Operating Partnership on each respective date:

	June 30, 2013			December 31, 2012
Outstanding noncontrolling common units of the Operating Partnership	25,526			170,526
Ownership interest in MPG Office, L.P. of outstanding noncontrolling common units	0.04		%	0.30		%
Aggregate redemption value of outstanding noncontrolling common units of the Operating Partnership (in thousands)	$	80.2		$	525.2

The aggregate redemption value does not necessarily represent the amount that would be distributed with respect to each noncontrolling common unit in the event of a termination or liquidation of MPG Office Trust, Inc. and the Operating Partnership. In the event of a termination or liquidation of MPG Office Trust, Inc. and the Operating Partnership, it is expected that in most cases each noncontrolling common unit would be entitled to a liquidating distribution equal to the amount payable with respect to each share of the Company’s common stock.

During the three and six months ended June 30, 2013, our limited partners’ weighted average share of our net income was 0.21% and 0.24%, respectively. During the three and six months ended June 30, 2012, our limited partners’ weighted average share of our net income was 10.90% and 11.10%, respectively.

Note 11—Earnings per Share

Basic net income or loss available to common stockholders is computed by dividing reported net income or loss available to common stockholders by the weighted average number of common and contingently issuable shares outstanding during each period. As discussed in Note 9 to the consolidated financial statements in the 2012 Form 10-K, we do not issue common stock in settlement of vested restricted stock unit awards until the earliest to occur of (1) the second, third or fifth anniversary of the grant date, depending upon the vesting period per the grant agreement, (2) the occurrence of a change in control (as defined in the underlying grant agreements), or (3) the recipient’s separation from service. In accordance with the provisions of FASB Codification Topic 260, EarningsPer Share, we include vested restricted stock units in the calculation of basic income or loss per share since the shares will be issued for no cash consideration, and all the necessary conditions for issuance have been satisfied as of the vesting date.

A reconciliation of our net income per share is as follows (in thousands, except share and per share amounts):

Note 13—Income Taxes

We elected to be taxed as a REIT under Sections 856 to 860 of the Internal Revenue Code of 1986, as amended (the “Code”), commencing with our tax year ended December 31, 2003. We believe that we have always operated so as to continue to qualify as a REIT. Accordingly, we will not be subject to U.S. federal income tax, provided that we continue to qualify as a REIT and our distributions to our stockholders equal or exceed our taxable income.

However, qualification and taxation as a REIT depends upon our ability to meet the various qualification tests imposed under the Code related to annual operating results, asset diversification, distribution levels and diversity of stock ownership. Accordingly, no assurance can be given that we will be organized or be able to operate in a manner so as to qualify or remain qualified as a REIT. If we fail to qualify as a REIT in any taxable year, we will be subject to federal and state income tax (including any applicable alternative minimum tax (“AMT”)) on our taxable income at regular corporate tax rates, and we may be ineligible to qualify as a REIT for four subsequent tax years. We may also be subject to certain state or local income taxes, or franchise taxes on our REIT activities.

We have elected to treat certain of our subsidiaries as taxable REIT subsidiaries (“TRS”). Certain activities that we undertake must be conducted by a TRS, such as non-customary services for our tenants, and holding assets that we cannot hold directly. A TRS is subject to both federal and state income taxes.

We recorded the following tax (benefit) provision as part of other expense in the consolidated statements of operations (in thousands):

	For the Six Months Ended

MPG Office Trust, Inc. and certain of our TRS entities had the following net operating loss (“NOL”) carryforwards (in millions, except years):

	Earliest Expiration Year	December 31, 2012
Federal: (1)
MPG Office Trust, Inc.	2028	$	715
TRS entities (2)	2027	130
		$	845
State: (1)
MPG Office Trust, Inc.	2017	$	827
TRS entities (2)	2014	62
		$	889

_________

(1) We recorded a full valuation allowance against these deferred tax assets since we did not expect to realize any of our NOL carryforwards as of June 30, 2013.

(2) While we are still determining what business activities will be conducted at our TRS entities in the future, it is not likely that we will utilize any of the December 31, 2012 NOL carryforwards at these entities.

On April 23, 2013, MPG TRS Holdings II, Inc. was liquidated for purposes of Section 331 of the Code as a result of being merged with and into its parent.

These amounts can be used to offset future taxable income (and/or taxable income for prior years if the audit of any prior year’s return determines that amounts are owed), if any. We may utilize NOL carryforwards only to the extent that REIT taxable income exceeds our deduction for dividends paid to our stockholders. In the absence of distributions to stockholders, our NOL carryforwards may fully offset REIT taxable income for federal income tax purposes. Our ability to use NOL carryforwards in 2013 and future years could be negatively impacted by changes in ownership of the Company, as defined under Section 382 of the Code (which generally limits the amount of NOL carryforwards that may be used on an annual basis in post-change tax years), or by legislative action within the jurisdictions in which we own property. As of June 30, 2013, all of our properties are located within the State of California. Under prior California law, NOL carryforwards were suspended in 2002, 2003 and from 2008 through 2011 and could not be used to offset taxable income for California franchise tax purposes in such tax years.

Note 14—Financial Instruments

Derivative Financial Instruments

Interest rate fluctuations may impact our results of operations and cash flow. Some of our mortgage loans bear interest at a variable rate. To minimize the volatility that changes in interest rates have on our variable-rate debt, we entered into interest rate swap and cap agreements with major financial institutions based on their credit rating and other factors. We do not trade in financial instruments for speculative purposes. Our derivatives are designated as cash flow hedges. The effective portion of changes in the fair value of cash flow hedges is initially reported in other accumulated comprehensive income in the consolidated balance sheet and is recognized as part of interest expense in the consolidated statement of operations when the hedged transaction affects earnings. The ineffective portion of changes in the fair value of cash flow hedges is recognized as part of interest expense in the consolidated statement of operations in the current period.

A summary of the effect of derivative financial instruments reported in the consolidated financial statements was as follows (in thousands):

	Amount of Gain Recognized in AOCI		Amount of Gain Reclassified from AOCI to Statement of Operations		Location of Gain Recognized in Statement of Operations
Derivatives designated as cash flow     hedging instruments:
Interest rate swap for the six months ended:
June 30, 2012	$	9,571	$	649	Interest expense

Interest Rate Swap—

Prior to August 9, 2012, we held an interest rate swap with a notional amount of $425.0 million, of which $400.0 million was assigned to the KPMG Tower mortgage loan. We recorded unrealized gains totaling $0.6 million as part of continuing operations during the six months ended June 30, 2012 due to hedge ineffectiveness related to this swap. Our interest rate swap expired on August 9, 2012.

Interest Rate Caps—

We held an interest rate cap with a notional amount of $33.6 million as of June 30, 2013 and December 31, 2012 whose fair value was immaterial. The interest rate cap was terminated as a result of the sale of Plaza Las Fuentes on July 18, 2013.

Other Financial Instruments

Our financial instruments include cash, cash equivalents, restricted cash, rents and other receivables, and accounts payable and accrued liabilities. The carrying amount of these instruments approximates fair value because of their short-term nature.

The estimated fair value and the carrying amount of our mortgage loans (excluding mortgage and mezzanine loans associated with Plaza Las Fuentes, which is held for sale as of June 30, 2013) are as follows (in millions):

	June 30, 2013
Estimated fair value	$	1,180
Carrying amount	1,639

We calculated the fair value of our mortgage loans based on currently available market rates assuming the loans are outstanding through maturity and considering the collateral. In determining the current market rate for our debt, a market spread is added to the quoted yields on federal government treasury securities with similar maturity dates to our debt.

Note 15—Subsequent Events

Approval of Merger

On July 17, 2013, the Company’s common stockholders voted to approve the merger of the Company with REIT Merger Sub and the other transactions contemplated by the Merger Agreement. The Company expects the merger to close in the third quarter of 2013, following fulfillment of the conditions to closing, including receipt of required lender consents.

Sale of Plaza Las Fuentes

On July 18, 2013, we sold Plaza Las Fuentes to affiliates of East West Bank and Downtown Properties Holdings, LLC. The purchase price was $75.0 million. Net proceeds from the transaction were approximately $30 million, which may potentially be used to make loan re-balancing payments on our upcoming 2013 debt maturities at KPMG Tower and 777 Tower. The $32.7 million mortgage and $11.3 million mezzanine loan balances were repaid at closing using proceeds from the transaction.

Merger-Related Litigation

Following the announcement of the execution of the Merger Agreement, seven putative class actions were filed against the Company, the members of the Company’s board of directors, the Operating Partnership, Brookfield, Sub REIT, REIT Merger Sub, Partnership Merger Sub and Brookfield DTLA Inc. Five of these lawsuits were filed on behalf of the Company’s common stockholders: (i) two lawsuits, captioned Coyne v. MPG Office Trust, Inc., et al., No. BC507342 (the “Coyne Action”), and Masih v. MPG Office Trust, Inc., et al., No. BC507962 (the “Masih Action”), were filed in the Superior Court of the State of California in Los Angeles County on April 29, 2013 and May 3, 2013, respectively; and (ii) three lawsuits, captioned Kim v. MPG Office Trust, Inc. et al., No. 24-C-13-002600 (the “Kim Action”), Perkins v. MPG Office Trust, Inc., et al., No. 24‑C-13-002778 (the “Perkins Action”) and Dell’Osso v. MPG Office Trust, Inc., et al., No. 24-C-13-003283 (the “Dell’Osso Action”) were filed in the Circuit Court for Baltimore City, Maryland on May 1, 2013, May 8, 2013 and May 22, 2013, respectively (collectively, the “Common Stock Actions”). Two lawsuits, captioned Cohen v. MPG Office

Trust, Inc.et al., No. 24‑C-13-004097 (the “Cohen Action”) and Donlan v. Weinstein, et al., No. 24‑C-13-004293 (the “Donlan Action”), were filed on behalf of the Company’s preferred stockholders in the Circuit Court for Baltimore City, Maryland on June 20, 2013 and July 2, 2013, respectively (collectively, the “Preferred Stock Actions,” together with the Common Stock Actions, the “Merger Litigations”).

In each of the Common Stock Actions, the plaintiffs allege, among other things, that the Company’s board of directors breached their fiduciary duties in connection with the merger by failing to maximize the value of the Company and ignoring or failing to protect against conflicts of interest, and that the relevant Brookfield Parties named as defendants aided and abetted those breaches of fiduciary duty. The Kim Action further alleges that the Operating Partnership also aided and abetted the breaches of fiduciary duty by the Company’s board of directors, and the Dell’Osso Action further alleges that the Company and the Operating Partnership aided and abetted the breaches of fiduciary duty by the Company’s board of directors. On June 4, 2013, the Kim and Perkins plaintiffs filed identical, amended complaints in the Circuit Court for Baltimore City, Maryland. On June 5, 2013, the Masih plaintiffs also filed an amended complaint in the Superior Court of the State of California in Los Angeles County. The three amended complaints, as well as the Dell’Osso Action complaint, allege that the preliminary proxy statement filed by the Company with the SEC on May 21, 2013 is false and/or misleading because it fails to include certain details of the process leading up to the merger and fails to provide adequate information concerning the Company’s financial advisors.

In each of the Preferred Stock Actions, which were brought on behalf of Company’s preferred stockholders, the plaintiffs allege, among other things, that, by entering into the Merger Agreement and tender offer, the Company breached the Articles Supplementary, which governs the issuance of the Company Preferred Shares, that the Company’s board of directors breached their fiduciary duties by agreeing to a Merger Agreement that violated the preferred stockholders’ contractual rights and that the relevant Brookfield Parties named as defendants aided and abetted those breaches of contract and fiduciary duty. On July 15, 2013, the plaintiffs in the Preferred Stock Actions filed a joint amended complaint in the Circuit Court for Baltimore City, Maryland that further alleges that the Company’s board of directors failed to disclose material information regarding Brookfield’s extension of the tender offer. On that same day, an intervenor plaintiff, preferred stockholder EJF Debt Opportunities Master Fund, L.P., EJF Debt Opportunities Master Fund II, LP, and EJF Select Master Fund (collectively ‘‘EJF’’), filed a brief in support of the Cohen and Donlan plaintiffs’ motion for preliminary injunction, which included additional allegations that (i) the Company’s board of directors breached their fiduciary duties by entering into a transaction that favored the common stockholders and disfavored the preferred stockholders; and (ii) the disclosures filed by the Company and Brookfield are misleading because the new preferred shares will not have the same rights as the existing preferred shares because of the ability of other Brookfield subsidiaries to issue securities that will have an effective priority over the new preferred shares.

The plaintiffs in the seven lawsuits seek an injunction against the merger, rescission or rescissory damages in the event the merger has been consummated, an award of fees and costs, including attorneys’ and experts’ fees, and other relief.

By letter dated June 13, 2013, plaintiffs in the Kim, Perkins, and Dell’Osso actions jointly requested that the Circuit Court for Baltimore City, Maryland issue a stay of the cases in Maryland, pending the resolution of the Coyne Action and the Masih Action in California. On June 25, 2013, the Superior Court of the State of California in Los Angeles County ordered the Coyne Action and the Masih Action to be consolidated (the “Consolidated Common Stock Action”).

On July 10, 2013, solely to avoid the costs, risks and uncertainties inherent in litigation, the Company and the other named defendants in the Consolidated Common Stock Action signed a memorandum of understanding (the ‘‘MOU’’), regarding a proposed settlement of all claims asserted therein. The MOU provides, among other things, that the parties will seek to enter into a stipulation of settlement which provides for the release of all asserted claims. The asserted claims will not be released until such stipulation of settlement is approved by the court. There can be no assurance that the parties will ultimately enter into a stipulation of settlement or that the court will approve such settlement even if the parties were to enter into such stipulation. Additionally, as part of the MOU, the Company agreed (i) to make certain additional disclosures related to the merger, which were filed with the SEC on a Schedule 14A dated July 11, 2013, (ii) to amend the Merger Agreement to allow the Company to release third parties currently subject to confidentiality agreements with the Company from any standstill restrictions contained in such agreements and (iii) to file a Current Report on Form 8-K and related press release (which were respectively filed and issued on July 11, 2013). Finally, in connection with the proposed settlement, plaintiffs in the Consolidated Common Stock Action intend to seek, and the defendants have agreed to pay, an award of attorneys’ fees and expenses in an amount to be determined by the Superior Court of the State of California in Los Angeles County. This payment will not affect the amount of consideration to be received by the Company’s stockholders pursuant to the terms of the Merger Agreement.

In the Preferred Stock Actions, at a hearing on July 24, 2013, the Circuit Court for Baltimore City, Maryland denied plaintiffs’ motion for a preliminary injunction that sought to enjoin the tender offer and the merger.
