On January 23, 2018, Saul Centers sold, in an underwritten public offering, 3.0 million depositary shares, each representing 1/100th of a share of 6.125% Series D Cumulative Redeemable Preferred Stock (the "Series D Stock"), providing net cash proceeds of approximately $72.6 million. The depositary shares may be redeemed at the Company’s option, in whole or in part, on or after January 23, 2023, at the $25.00 liquidation preference, plus accrued but unpaid dividends to but not including the redemption date.
