|Stock Compensation [Abstract]|
|Stock Compensation||11. Stock compensation Under various share-based compensation plans, PSB grants non-qualified options to purchase the Company’s common stock at a price not less than fair value on the date of grant, as well as RSUs, to certain directors, officers and key employees. The service period for stock options and RSUs begins when (i) the Company and the recipient reach a mutual understanding of the key terms of the award, (ii) the award has been authorized, (iii) the recipient is affected by changes in the market price of our stock and (iv) it is probable that any performance conditions will be met, and ends when the stock options or RSUs vest. We amortize the fair value of awards starting at the beginning of the service period as compensation expense. For awards that are earned solely upon the passage of time and continued service, the entire cost of the award is amortized on a straight-line basis over the service period. For awards with performance conditions, the individual cost of each vesting is amortized separately over each individual service period (the “accelerated attribution” method). In connection with the appointment of our President and Chief Executive Officer (“CEO”) effective April 5, 2021, the Company granted a one-time RSU sign-on award with a grant date fair value of $3.7 million and a retention RSU award with a grant date fair value of $2.9 million. These RSUs will vest ratably over five years. Effective September 1, 2020, Maria Hawthorne retired from her role as President and CEO and continues to serve as a director of the Company. Due to Ms. Hawthorne’s continued service as a director of the Company, her unvested stock options and restricted stock units will continue to vest on their original vesting schedule in accordance with the Company’s 2012 Equity and Performance-Based Incentive Compensation Plan and related award agreements. For financial reporting purposes, the end of the service periods for these stock option and restricted stock unit grants have changed from the various respective vesting dates to September 1, 2020, the date of her retirement as President and CEO. Accordingly, all remaining stock compensation expense for Ms. Hawthorne, which totaled $1.7 million, was amortized and included in general and administrative expense during the three and nine months ended September 30, 2020. We account for forfeitures of share-based payments as they occur by reversing previously amortized share-based compensation expense with respect to unvested grants that are forfeited in the period the employee terminates employment. Stock Options Stock options expire 10 years after the grant date and the exercise price is equal to the closing trading price of our common stock on the grant date. Stock option holders cannot require the Company to settle their award in cash. We use the Black-Scholes option valuation model to estimate the fair value of our stock options on the date of grant. For the three and nine months ended September 30, 2021, we recorded $0.1 million and $0.5 million, respectively, in compensation expense related to stock options as compared to $0.1 million and $0.3 million for the same periods in 2020, respectively. During the nine months ended September 30, 2021, 28,000 stock options were granted, 14,478 options were exercised and no options were forfeited. A total of 185,216 and 171,694 options were outstanding at September 30, 2021 and December 31, 2020, respectively. Restricted Stock Units RSUs granted prior to 2016 are subject to a six-year vesting, with 20% vesting after year two, and 20% vesting after each of the next four years. RSUs granted during and subsequent to 2016 are subject to a five-year vesting at the rate of 20% per year or a three-year vesting at the rate of one-third per year. Grantees receive dividends for each outstanding RSU equal to the per share dividend received by common stockholders, which are recorded in paid-in capital. We expense any dividends previously paid upon forfeiture of the related RSU. Upon vesting, the grantee receives shares of common stock equal to the number of vested RSUs, less shares of common stock withheld in exchange for tax withholdings made by the Company to satisfy the grantee’s statutory tax liabilities arising from the vesting. The fair value of our RSUs is determined based upon the applicable closing trading price of our common stock on the date of grant. In March 2020, the Compensation Committee of the Board approved an annual performance-based equity incentive program (“Annual Equity Incentive Program”) under the Company’s 2012 Equity and Performance-Based Incentive Compensation Plan. Under the program, certain employees will be eligible on an annual basis to receive RSUs based on the Company’s achievement of pre-established targets for (i) growth in net asset value per share, and (ii) stockholder value creation, each as computed pursuant to the terms of the Annual Equity Incentive Program. In the event the pre-established targets are achieved, eligible employees will receive the target award, except that the Compensation Committee of the Board may adjust the actual award to 75% to 125% of the target award based on its assessment of whether certain strategic and operational goals were accomplished in the performance period. RSUs awarded under the Annual Equity Incentive Program for the 2021 performance year will be awarded on or around March 1, 2022 and will vest in five equal installments, with the first installment vesting on the award date. RSU holders will earn dividend equivalent rights during the vesting period. For the three and nine months ended September 30, 2021, respectively, we recorded $1.9 million and $5.1 million in compensation expense related to RSUs as compared to $2.2 million and $3.5 million for the same periods in 2020. During the nine months ended September 30, 2021, 74,435 RSUs were granted, 57,063 RSUs vested and 17,110 RSUs were forfeited. Tax withholdings totaling $3.7 million were made on behalf of employees in exchange for 23,935 shares of common stock withheld upon vesting for the nine months ended September 30, 2021 resulting in the issuance of 33,128 shares of common stock. Tax withholdings totaling $4.1 million were made on behalf of employees in exchange for 28,877 shares of common stock withheld upon vesting for the nine months ended September 30, 2020 resulting in the issuance of 41,699 shares of common stock. A total of 121,770 and 121,508 RSUs were outstanding at September 30, 2021 and December 31, 2020, respectively. Of the 74,435 RSUs granted during the nine months ended September 30, 2021, 41,186 RSUs were granted to our President and CEO in April 2021 (discussed above), 10,955 were granted to our Chief Financial Officer, and 16,970 were granted in aggregate to our Divisional Vice Presidents. Under the Retirement Plan for Non-Employee Directors (the “Director Retirement Plan”), the Company grants 1,000 shares of common stock for each year served as a director up to a maximum of 10,000 shares issued upon retirement. The Company recognizes compensation expense with regard to grants to be issued in the future under the Director Retirement Plan over the requisite service period. For the three and nine months ended September 30, 2021, respectively, we recorded $0.3 million and $0.8 million in compensation expense related to these shares as compared to $0.2 million and $0.6 million for the same periods in 2020, respectively. In April 2021, we issued 10,000 shares of common stock to a director upon retirement with an aggregate fair value of $1.6 million. Compensation expense for these shares was previously recognized. No director retirement shares were issued during the nine months ended September 30, 2020.|
