NOTE 10. EQUITY

Noncontrolling Interests

Noncontrolling interests in our Operating Partnership are interests in the Operating Partnership that are not owned by us. Noncontrolling interests consisted of 18,396,089 common units (the "noncontrolling common units"), and represented approximately 32% of the ownership interests in our Operating Partnership at June 30, 2011. Common units and shares of our common stock have essentially the same economic characteristics in that common units and shares of our common stock share equally in the total net income or loss distributions of our Operating Partnership. Investors who own common units have the right to cause our Operating Partnership to redeem any or all of their common units for cash equal to the then-current market value of one share of our common stock, or, at our election, shares of our common stock on a one-for-one basis.

On February 14, 2011, we completed a private placement transaction of 251,050 common units for approximately $5.4 million.

Dividends

During the second quarter of 2011, we declared and paid dividends on our shares of common stock and noncontrolling common units of $0.21 per share and per unit for the second quarter. During the first quarter of 2011, we declared and paid dividends on our shares of common stock and noncontrolling common units of $0.17 per share and per unit for the period from and including January 19, 2011 to March 31, 2011.

Taxability of Dividends

Earnings and profits, which determine the taxability of distributions to stockholders and holders of common units, may differ from income reported for financial reporting purposes due to the differences for federal income tax purposes in the treatment of loss on extinguishment of debt, revenue recognition and compensation expense and in the basis of depreciable assets and estimated useful lives used to compute depreciation.

Stock-Based Compensation

Concurrently with the closing of the Offering, we made grants of restricted shares of our common stock to certain executive officers pursuant to the terms of their employment agreements. These awards were made pursuant to our 2011 Equity Incentive Award Plan (the "2011 Plan"). At such time, we granted to such executive officers a total of 198,000 shares that are subject to timing-based vesting and 297,000 shares that are subject to performance-based vesting, with fair market values of $4.1 million for the timing-based vesting awards and $3.9 million for the performance-based vesting awards. Those awards subject to time-based vesting will vest, subject to the recipient's continued employment, in two substantially equal installments on each of the third and fourth anniversaries of the date of grant. The vesting of those restricted stock awards subject to performance-based vesting is based on the achievement of absolute and relative total shareholder return hurdles over a three-year performance period, commencing on January 19, 2011. Following the completion of the three-year performance period, our compensation committee will determine the number of shares to which the executive officer is entitled based on our performance relative to the performance hurdles set forth in the restricted stock award agreement he entered into in connection with his initial award grant. These shares will then vest in two substantially equal installments, with the first installment vesting on the third anniversary of the date of grant and the second installment vesting on the fourth anniversary of the date of grant, subject to the executive officer's continued employment on those dates.

Concurrently with the closing of the Offering, we also granted each of our non-employee directors 1,951 restricted shares of our common stock pursuant to the 2011 Plan, other than one who was granted 1,952 restricted shares. These awards of restricted stock will vest ratably as to one-third of the shares granted on each of the first three anniversaries of the date of grant, subject to the director's continued service on our board of directors, and had an aggregate fair value of $0.2 million on the date of the grants. On June 29, 2011, one of our directors notified us of his resignation as a director of the Company and, as a result, immediately forfeited the 1,951 restricted shares of our common stock previously granted to him, none of which had vested.

On March 16, 2011 we granted a total of 123,950 restricted shares of our common stock to certain other employees pursuant to the 2011 Plan with a fair value of $1.6 million. These shares are subject to performance-based vesting, with the terms described above related to performance-based vesting.

For the performance-based stock awards, the fair value of the awards was estimated using a Monte Carlo Simulation model. The volatilities of the returns on the stock price of the Company and the group REITs were estimated based on a three year look-back period. The expected growth rate of the stock prices over the "derived service period" of the employee is determined with consideration of the risk free rate as of the grant date. For the restricted stock grants that are time-vesting, we estimate the stock compensation expense based on the fair value of the stock at the grant date.

None of the restricted shares were vested at June 30, 2011. We recognize noncash compensation expense ratably over the vesting period, and accordingly, we recognized $1.2 million in noncash compensation expense for the six months ended June 30, 2011, which is included in general and administrative expense on the statement of operations. Unrecognized compensation expense was $8.5 million.

Earnings Per Share

We have calculated earnings per share ("EPS") under the two-class method. The two-class method is an earnings allocation methodology whereby EPS for each class of common stock and participating security is calculated according to dividends declared and participation rights in undistributed earnings. For the three and six months ended June 30, 2011, we had a weighted average of approximately 628,663 and 527,812 unvested shares outstanding, respectively, which are considered participating securities. Therefore, we have allocated our earnings for basic and diluted EPS between common shares and unvested shares.

Diluted EPS is calculated by dividing the net income applicable to common stockholders for the period by the weighted average number of common and dilutive instruments outstanding during the period using the treasury stock method. Since we were in a net loss position for the six months ended June 30, 2011, all potentially dilutive instruments are anti-dilutive and have been excluded from our computation of weighted average dilutive shares outstanding. For the three and six months ended June 30, 2011, diluted shares exclude incentive restricted stock as these awards are considered contingently issuable. Additionally, the unvested restricted stock awards subject to time vesting are anti-dilutive for all periods presented and accordingly, have been excluded from the weighted average common shares used to compute diluted EPS.

The computation of basic and diluted EPS is presented below (dollars in thousands, except share and per share amounts):
