Base Management Fee And Incentive Fee [Abstract]
Base Management Fee and Incentive Fee	5. Base Management Fee and Incentive Fee The Company has engaged the Manager to manage the assets, operations and affairs of the Company and pays various management fees associated with that arrangement. Effective August 2, 2011, the Board of Directors approved a Third Amended and Restated Management Agreement between the Company and the Manager. The Base Management Fees and Incentive Fees payable under the agreement are detailed below. *Base Management Fees* The Manager receives an annual base management fee in an amount equal to 1.50% per annum of the Company's shareholders' equity as of the end of each fiscal quarter (before deductions for base management fee and incentive fee payable with respect to such fiscal quarter). The base management fee is payable quarterly in arrears. Summary information—For the three month periods ended September 30, 2012 and 2011, the total base management fee incurred by the Company was $1.9 million and $1.4 million, respectively. For the nine month periods ended September 30, 2012 and 2011, the total base management fee incurred by the Company was $4.9 million and $4.3 million, respectively. *Incentive Fee* The Manager is entitled to receive a quarterly incentive fee equal to the positive excess of (i) the product of (A) 25% and (B) the excess of (1) Adjusted Net Income (described below) for the Incentive Calculation Period (which means such fiscal quarter and the immediately preceding three fiscal quarters) over (2) the sum of the Hurdle Amounts (described below) for the Incentive Calculation Period, over (ii) the sum of the incentive fees already paid or payable for each fiscal quarter in the Incentive Calculation Period preceding such fiscal quarter. For purposes of calculating the incentive fee, "Adjusted Net Income," for the Incentive Calculation Period means the net increase in shareholders' equity from operations, after all base management fees but before any incentive fees for such period, and excluding non-cash equity compensation expenses for such period as reduced by any Loss Carryforward (as described below) as of the end of the fiscal quarter preceding the Incentive Calculation Period. For purposes of calculating the incentive fee, the "Loss Carryforward" as of the end of any fiscal quarter is calculated by determining the excess, if any, of (1) the Loss Carryforward as of the end of the immediately preceding fiscal quarter over (2) the net increase in shareholders' equity from operations (expressed as a positive number) or net decrease in shareholders' equity from operations (expressed as a negative number) for such fiscal quarter. As of September 30, 2012, there was no Loss Carryforward. For purposes of calculating the incentive fee, the "Hurdle Amount" means, with respect to any fiscal quarter, the product of (i) one-fourth of the greater of (A) 9% and (B) 3% plus the ten-year U.S. Treasury rate for such fiscal quarter, (ii) the sum of (A) the weighted average gross proceeds per share of all our common share issuances up to the end of such fiscal quarter, with each issuance weighted by both the number of shares issued in such issuance and the number of days that such issued shares were outstanding during such fiscal quarter, using a first-in first-out basis of accounting (i.e., attributing any share repurchases to the earliest issuances first) and (B) the result obtained by dividing (I) retained earnings attributable to common shares at the beginning of such fiscal quarter by (II) the average number of common shares outstanding for each day during such fiscal quarter, and (iii) the average number of common shares and LTIP units outstanding for each day during such fiscal quarter. For purposes of determining the Hurdle Amount, issuances of common shares (a) as equity incentive awards, (b) to the Manager as part of its base management fee or incentive fee and (c) to the Manager or any of its affiliates in privately negotiated transactions, are excluded from the calculation. The payment of the incentive fee will be in a combination of common shares and cash, provided that at least 10% of any quarterly payment will be made in common shares. Summary information—Total incentive fee incurred for the three month period ended September 30, 2012 was $9.5 million. No incentive fee was incurred for the three month period ended September 30, 2011. Total incentive fee incurred for the nine month periods ended September 30, 2012 and 2011 was $11.8 million and $0.6 million, respectively.

5. Base Management Fee and Incentive Fee

The Company has engaged the Manager to manage the assets, operations and affairs of the Company and pays various management fees associated with that arrangement. Effective August 2, 2011, the Board of Directors approved a Third Amended and Restated Management Agreement between the Company and the Manager. The Base Management Fees and Incentive Fees payable under the agreement are detailed below.

Base Management Fees

The Manager receives an annual base management fee in an amount equal to 1.50% per annum of the Company's shareholders' equity as of the end of each fiscal quarter (before deductions for base management fee and incentive fee payable with respect to such fiscal quarter). The base management fee is payable quarterly in arrears.

Summary information—For the three month periods ended September 30, 2012 and 2011, the total base management fee incurred by the Company was $1.9 million and $1.4 million, respectively. For the nine month periods ended September 30, 2012 and 2011, the total base management fee incurred by the Company was $4.9 million and $4.3 million, respectively.

Incentive Fee

The Manager is entitled to receive a quarterly incentive fee equal to the positive excess of (i) the product of (A) 25% and (B) the excess of (1) Adjusted Net Income (described below) for the Incentive Calculation Period (which means such fiscal quarter and the immediately preceding three fiscal quarters) over (2) the sum of the Hurdle Amounts (described below) for the Incentive Calculation Period, over (ii) the sum of the incentive fees already paid or payable for each fiscal quarter in the Incentive Calculation Period preceding such fiscal quarter.

For purposes of calculating the incentive fee, "Adjusted Net Income," for the Incentive Calculation Period means the net increase in shareholders' equity from operations, after all base management fees but before any incentive fees for such period, and excluding non-cash equity compensation expenses for such period as reduced by any Loss Carryforward (as described below) as of the end of the fiscal quarter preceding the Incentive Calculation Period.

For purposes of calculating the incentive fee, the "Loss Carryforward" as of the end of any fiscal quarter is calculated by determining the excess, if any, of (1) the Loss Carryforward as of the end of the immediately preceding fiscal quarter over (2) the net increase in shareholders' equity from operations (expressed as a positive number) or net decrease in shareholders' equity from operations (expressed as a negative number) for such fiscal quarter. As of September 30, 2012, there was no Loss Carryforward.

For purposes of calculating the incentive fee, the "Hurdle Amount" means, with respect to any fiscal quarter, the product of (i) one-fourth of the greater of (A) 9% and (B) 3% plus the ten-year U.S. Treasury rate for such fiscal quarter, (ii) the sum of (A) the weighted average gross proceeds per share of all our common share issuances up to the end of such fiscal quarter, with each issuance weighted by both the number of shares issued in such issuance and the number of days that such issued shares were outstanding during such fiscal quarter, using a first-in first-out basis of accounting (i.e., attributing any share repurchases to the earliest issuances first) and (B) the result obtained by dividing (I) retained earnings attributable to common shares at the beginning of such fiscal quarter by (II) the average number of common shares outstanding for each day during such fiscal quarter, and (iii) the average number of common shares and LTIP units outstanding for each day during such fiscal quarter. For purposes of determining the Hurdle Amount, issuances of common shares (a) as equity incentive awards, (b) to the Manager as part of its base management fee or incentive fee and (c) to the Manager or any of its affiliates in privately negotiated transactions, are excluded from the calculation. The payment of the incentive fee will be in a combination of common shares and cash, provided that at least 10% of any quarterly payment will be made in common shares.

Summary information—Total incentive fee incurred for the three month period ended September 30, 2012 was $9.5 million. No incentive fee was incurred for the three month period ended September 30, 2011. Total incentive fee incurred for the nine month periods ended September 30, 2012 and 2011 was $11.8 million and $0.6 million, respectively.
