Stock Repurchase Plan. On March 12, 2020, our Board of Directors authorized the repurchase of up to 5,000,000 outstanding shares of common stock.

We may from time to time raise capital under our automatic shelf registration statement in amounts, at prices, and on terms to be announced when and if the securities are offered.
