Stock Repurchase Program
In November 2019, the Company's board of directors approved a stock repurchase program authorizing the Company to repurchase up to $50.0 million of its common stock from time to time over the next three years. Stock repurchases under this program may be made through open market transactions, negotiated purchases or otherwise, at times and in such amounts as the Company considers appropriate and in accordance with applicable regulations of the Securities and Exchange Commission. The timing of repurchases and the number of shares repurchased will depend on a variety of factors including price, regulatory requirements, and other market conditions. The Company may limit, amend, suspend, or terminate the stock repurchase program at any time without prior notice. Any shares repurchased under the program will be returned to the status of authorized, but unissued shares of common stock. As of December 31, 2019, the Company had repurchased 368,996 shares for approximately $5.0 million.
