Stock-Based Compensation

The Company recorded stock-based compensation in general and administrative expenses in the accompanying Consolidated Statements of Operations, the components of which are further described below for the years ended December 31, 2011, 2010, and 2009 (in thousands):



		2011		2010		2009
Restricted stock	$	10,659		7,236		5,227
Directors' fees paid in common stock		269		231		279
Less: Amount capitalized		(1,104	)	(852	)	(1,574	)
Total	$	9,824		6,615		3,932

The recorded amounts of stock-based compensation expense represent amortization of the grant date fair value of restricted stock awards over the respective vesting periods. Compensation expense specifically identifiable to development and leasing activities is capitalized and included above.

The Company established the Plan under which the Board of Directors may grant stock options and other stock-based awards to officers, directors, and other key employees. The Plan allows the Company to issue up to approximately 4.1 million shares in the form of the Parent Company's common stock or stock options. At December 31, 2011, there were approximately 3.2 million shares available for grant under the Plan either through options or restricted stock.

Stock options are granted under the Plan with an exercise price equal to the Parent Company's stock's price at the date of grant. All stock options granted have ten-year lives, contain vesting terms of one to five years from the date of grant and some have dividend equivalent rights.

The fair value of each option award is estimated on the date of grant using the Black-Scholes-Merton closed-form (“Black-Scholes”) option valuation model. The Company believes that the use of the Black-Scholes model meets the fair value measurement objectives of FASB ASC Topic 718 and reflects all substantive characteristics of the instruments being valued.

The Company grants restricted stock under the Plan to its employees as a form of long-term compensation and retention. The terms of each grant vary depending upon the participant's responsibilities and position within the Company. The Company's stock grants can be categorized as either time-based awards, performance-based awards, or market-based awards. All awards were valued at the fair market value on the date of grant, earn dividends throughout the vesting period, and have no voting rights. Compensation expense is measured at the grant date and recognized over the vesting period.


•	Time-based awards vest 25% per year beginning on the first anniversary following the grant date. These grants are subject only to continued employment and not dependent on future performance measures; and accordingly, if such vesting criteria are not met, compensation cost previously recognized would be reversed. During 2011, the Company granted 128,139 shares of time-based awards.

•

Performance-based awards are earned subject to future performance measurements, including individual goals, annual growth in earnings, and compounded three-year growth in earnings. Once the performance criteria are achieved and the actual number of shares earned is determined, shares will vest over a required service period. If such performance criteria are not met, compensation cost previously recognized would be reversed. The Company considers the likelihood of meeting the performance criteria based upon managements' estimates from which it determines the amounts recognized as expense on a periodic basis. During 2011, the Company granted 18,246 shares of performance-based awards.

•

Market-based awards are earned dependent upon the Company's total shareholder return in relation to the shareholder return of peer indices over a three-year period (“TSR Grant”). Once the market criteria are met and the actual number of shares earned is determined, 100% of the earned shares vest. The probability of meeting the market criteria is considered when calculating the estimated fair market value on the date of grant using a Monte Carlo simulation. These awards were accounted for as awards with market criteria, with compensation cost recognized over the service period, regardless of whether the market criteria are achieved and the awards are ultimately earned and vest. During 2011, the Company granted 165,689 shares of market-based awards.

As of December 31, 2011, there was $13.3 million of unrecognized compensation cost related to non-vested restricted stock granted under the Parent Company's Long-Term Omnibus Plan. When recognized, this compensation results in additional paid in capital in the accompanying Consolidated Statements of Equity and Comprehensive Income (Loss) of the Parent Company and in general partner preferred and common units in the accompanying Consolidated Statements of Capital and Comprehensive Income (Loss) of the Operating Partnership. This unrecognized compensation cost is expected to be recognized over the next three years, through 2014. The Company issues new restricted stock from its authorized shares available at the date of grant.

The Company maintains a 401(k) retirement plan covering substantially all employees, which permits participants to defer up to the maximum allowable amount determined by the IRS of their eligible compensation. This deferred compensation, together with Company matching contributions equal to 100% of employee deferrals up to a maximum of $4,000 of their eligible compensation, is fully vested and funded as of December 31, 2011. Costs related to matching portion of the plan were $1.2 million, $1.1 million, and $1.4 million for the years ended December 31, 2011, 2010, and 2009, respectively.
