Stock-Based Compensation [Abstract]
Stock-Based Compensation	8. STOCK-BASED COMPENSATION Our 2016 Omnibus Stock Plan, which was adopted in May 2016 replacing the expiring 2006 Omnibus Stock Plan, provides for grants of incentive and non-qualified stock options, restricted stock, stock appreciation rights, deferred stock units (“DSUs”) and performance shares, as defined, to the directors, officers and employees of the Company and Vornado, and any other person or entity as designated by the Omnibus Stock Plan Committee of our Board of Directors. As of December 31, 2016, there were 8,505 DSUs outstanding and 498,376 shares were available for future grant under the 2016 Omnibus Stock Plan. We account for all stock-based compensation in accordance with ASC 718. In May 2016, we granted each of the members of our Board of Directors 203 DSUs with a grant date fair value of $56,250 per grant, or $450,000 in the aggregate. The DSUs entitle the holders to receive shares of the Company’s common stock without the payment of any consideration. The DSUs vested immediately and accordingly, were expensed on the date of grant, but the shares of common stock underlying the DSUs are not deliverable to the grantee until the grantee is no longer serving on the Company’s Board of Directors.
