Dividend Investment Plan [Abstract] |
Dividend Investment Plan | Dividend Investment Plan The Company has a Dividend Investment Plan, which allows participants’ dividends to purchase additional shares of common stock at its fair market value on each dividend record date. During 2016, the Company amended the Plan to provide that shares of common stock purchased through the Plan would be purchased at a price equal to the market price of the shares. Prior to this date, the Plan allowed participants' dividends to purchase additional shares of common stock at 95% of its fair market value. Our board of directors determined to eliminate the discount for purchases of shares in order to reflect current best practices and market standards for dividend reinvestment plans generally and among our peers. No other changes have been made to the operation of the dividend reinvestment features of the Plan, and current participants will remain enrolled in the Plan under their current methods of participation unless they choose to alter their enrollment following the procedures described in this prospectus.
