Historic Tax Credits [Abstract]
Historic Tax Credits	HISTORIC TAX CREDITS Phase I In the third quarter of 2009, we closed a transaction with a counterparty (the “Phase I Counterparty”) related to the historic rehabilitation of an office building located at 801 Market Street in Philadelphia, Pennsylvania (the “Phase I Project”). Capital contributions received from the Phase I Counterparty are, in substance, consideration that we received in exchange for a put option (whereby we might be obligated or entitled to repurchase the Phase I Counterparty’s ownership interest in the Phase I Project) and our obligation to deliver tax credits to the Phase I Counterparty. The Phase I Counterparty’s contributions, other than the amounts allocated to the put option, are classified as “Noncontrolling interest” and recognized as “Other income” in the consolidated financial statements as our obligation to deliver tax credits is relieved. The tax credits are subject to a five year credit recapture period, as defined in the Internal Revenue Code of 1986, as amended, beginning one year after the completion of the Phase I Project, which was completed in the third quarter of 2009. Our obligation to the Phase I Counterparty with respect to the tax credits is ratably relieved annually in the third quarter of each year, upon the expiration of each portion of the recapture period and the satisfaction of other revenue recognition criteria. In the third quarter of 2013, we recognized the amount related to the fourth recapture period and recorded $1.8 million of the contribution received from the Phase I Counterparty as “Other income” in the consolidated statements of operations. Phase II In the second quarter of 2012, we closed a transaction with a Phase II Counterparty (the “Phase II Counterparty”) related to the historic rehabilitation of an office building located at 801 Market Street in Philadelphia, Pennsylvania (the “Phase II Project”). The Phase II Counterparty agreed to initially contribute $3.7 million of equity to the Phase II Project. This amount was subsequently increased to $5.5 million, of which $4.0 million was funded as of September 30, 2013. In exchange for its contributions into the Phase II Project, the Phase II Counterparty received substantially all of the historic rehabilitation tax credits associated with the Phase II Project as a distribution. The Phase II Counterparty’s contributions, other than the amounts allocated to a put option (whereby we might be obligated or entitled to repurchase the Phase II Counterparty’s ownership interest in the Phase II Project), are classified as “Accrued expenses and other liabilities” and recognized as “Other income” in the consolidated financial statements as our obligation to deliver tax credits is relieved. The tax credits are subject to a five year credit recapture period, as defined in the Internal Revenue Code of 1986, as amended, beginning one year after the completion of the Phase II Project, which was completed in the second quarter of 2012. Our obligation to the Phase II Counterparty with respect to the tax credits is ratably relieved annually in the third quarter of each year, upon the expiration of each portion of the recapture period and the satisfaction of other revenue recognition criteria. In the third quarter of 2013, we recognized the amount related to the first recapture period and recorded $0.7 million of the contribution received from the Phase II Counterparty as “Other income” in the consolidated statements of operations.
