Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2013

The consolidated financial statements include the accounts of COPT, the Operating Partnership, their subsidiaries and other entities in which we have a majority voting interest and control. We also consolidate certain entities when control of such entities can be achieved through means other than voting rights (“variable interest entities” or “VIEs”) if we are deemed to be the primary beneficiary of such entities. We eliminate all significant intercompany balances and transactions in consolidation.

We use the equity method of accounting when we own an interest in an entity and can exert significant influence over the entity’s operations but cannot control the entity’s operations. We discontinue equity method accounting if our investment in an entity (and net advances) is reduced to zero unless we have guaranteed obligations of the entity or are otherwise committed to provide further financial support for the entity.

We use the cost method of accounting when we own an interest in an entity and cannot exert significant influence over its operations.

These interim financial statements should be read together with the financial statements and notes thereto as of and for the year ended December 31, 2012 included in our 2012 Annual Report on Form 10-K. The unaudited consolidated financial statements include all adjustments that are necessary, in the opinion of management, to fairly present our financial position and results of operations. All adjustments are of a normal recurring nature except for errors described below. The consolidated financial statements have been prepared using the accounting policies described in our 2012 Annual Report on Form 10-K.

Reclassifications

We reclassified certain amounts from prior periods to conform to the current period presentation of our consolidated financial statements with no effect on previously reported net income or equity.

Revisons

Revisions

As reported in our 2012 Annual Report on Form 10-K, we identified the following errors in 2012:

•

the misapplication of accounting guidance related to the recognition of a deferred tax asset resulting from an impairment of assets in the fourth quarter of 2011 that failed to consider a partial reversal of that asset that would result from a cancellation of related inter-company debt in the first quarter of 2012. The effect of this error was an overstatement of our income tax benefit and an understatement of our net loss for the year ended December 31, 2011 of $4.0 million. Based on an evaluation against our projected annual net income at that time, this error was previously reported as an out-of-period adjustment in the three months ended March 31, 2012;

•

an over-accrual of incentive compensation cost, the effect of which was an overstatement of general and administrative expenses and an overstatement of net loss for the calendar quarter and year ended December 31, 2011 of $711,000. Based on an evaluation against our projected annual net income at that time, this error was previously reported as an out-of-period adjustment in the three months ended March 31, 2012;

•

the misapplication of accounting guidance requiring that we recognize loss allocations to a noncontrolling interest holder in a consolidated real estate joint venture associated with decreases in such holder's claim on the book value of the joint venture’s assets, despite the fact that the real estate held by the joint venture was under development and the joint venture had no underlying losses. The effect of this error was an understatement of losses attributable to noncontrolling interests in other consolidated entities of $1.8 million for the nine months ended September 30, 2012 and $1.4 million for the year ended December 31, 2011; and

•

the misapplication of accounting guidance pertaining to our reporting for a noncontrolling interest in a consolidated real estate joint venture formed in March 2010 for which the holder of such interest has the right to require us to acquire the interest at fair value. Accounting guidance requires that this noncontrolling interest be classified outside of permanent equity and reported at fair value as of the end of each reporting period, with changes in such fair value reported as equity transactions with no impact to net income or comprehensive income. This error resulted in an overstatement of equity and offsetting understatement of the line entitled “redeemable noncontrolling interest” in the mezzanine section of our consolidated balance sheet of $8.9 million as of December 31, 2011. This error had no effect on our consolidated statements of operations, including our reported net income (losses) or earnings per share.

With respect to the errors in the first two bullets above, we assessed the materiality of these errors on the financial statements in connection with previously filed periodic reports, in accordance with ASC 250 (SEC’s Staff Accounting Bulletin No. 99, “Materiality”), and concluded at such time that the errors were not material to any prior annual or interim periods. In assessing the cumulative effect of all such errors, we have considered ASC 250 (SEC Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements”), and accordingly, the financial statements as of, and for the year ended, December 31, 2011 were revised in our 2012 Annual Report on Form 10-K. We have revised amounts pertaining to the first quarter of 2012 herein and will revise amounts pertaining to the remaining 2012 calendar quarters ended June 30, 2012 and September 30, 2012 in future quarterly filings on Form 10-Q.

Recent Accounting Pronouncements

We adopted guidance issued by the Financial Accounting Standards Board (“FASB”) effective January 1, 2013 related to the reporting of the effect of significant reclassifications from accumulated other comprehensive income. This guidance requires an entity to report, either parenthetically on the face of the financial statements or in a single footnote, changes in the components of accumulated other comprehensive income for the period. An entity is required to separately report the amount of such changes attributable to reclassifications (and the statements of operations line affected by such reclassifications) and the amount of such changes attributable to current period other comprehensive income. For amounts that are not required to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures that provide additional detail about those amounts. Our adoption of this guidance did not affect our consolidated financial statements or disclosures.
