Noncontrolling Interests on the Company's Consolidated Financial Statements	Noncontrolling Interests on the Company’s Consolidated Financial Statements Common Units of the Operating Partnership The Company owned a 98.1% and 98.0% common general partnership interest in the Operating Partnership as of December 31, 2015 and 2014, respectively. The remaining 1.9% and 2.0% common limited partnership interest as of December 31, 2015 and 2014, respectively, was owned by non-affiliated investors and certain of our executive officers and directors in the form of noncontrolling common units. There were 1,764,775 and 1,804,200 common units outstanding held by these investors, executive officers and directors as of December 31, 2015 and 2014, respectively. The noncontrolling common units may be redeemed by unitholders for cash. Except under certain circumstances, we, at our option, may satisfy the cash redemption obligation with shares of the Company’s common stock on a one-for-one basis. If satisfied in cash, the value for each noncontrolling common unit upon redemption is the amount equal to the average of the closing quoted price per share of the Company’s common stock, par value $0.01 per share, as reported on the NYSE for the ten trading days immediately preceding the applicable redemption date. The aggregate value upon redemption of the then-outstanding noncontrolling common units was $112.0 million and $126.8 million as of December 31, 2015 and 2014, respectively. This redemption value does not necessarily represent the amount that would be distributed with respect to each noncontrolling common unit in the event of our termination or liquidation. In the event of our termination or liquidation, it is expected in most cases that each common unit would be entitled to a liquidating distribution equal to the liquidating distribution payable in respect of each share of the Company’s common stock.

This noncontrolling interest was $6.5 million and $5.9 million at December 31, 2015 and 2014, respectively.
