In 2011, our Board of Directors approved a continuation of the current stock repurchase program of $150 million, with no time limitation.  There were no shares repurchased under this program during the nine months ended September 30, 2021 and the year ended December 31, 2020. We had approximately $17.8 million of repurchase authority remaining under this program at September 30, 2021.
