Equity [Abstract] |
SHARE REPURCHASE PLAN | SHARE REPURCHASE PLAN On March 19, 2018, our Board of Directors authorized a $50 million share repurchase plan. This repurchase authorization, which was effective through August 31, 2019, permitted us to repurchase from time to time up to $50 million in aggregate value of shares of our common stock through a combination of open market and privately negotiated repurchases. As of December 31, 2018, we repurchased 321,731 common shares at a total cost of $12.3 million, or an average of $38.10 per share. In 2019, we repurchased 470,708 common shares at a total cost of $18.2 million, or an average of $38.71 per share. Under the March 19, 2018 plan, we repurchased 792,439 common shares at a total cost of $30.5 million, or an average of $38.46 per share. On September 16, 2019, our Board of Directors authorized a new $50 million share repurchase plan. This repurchase authorization, which is effective through March 31, 2021, permits S&T to repurchase from time to time up to $50 million in aggregate value of shares of S&T's common stock through a combination of open market and privately negotiated repurchases. No common shares were repurchased under the new repurchase plan as of December 31, 2019. As of December 31, 2020, we repurchased 411,430 common shares at a total cost of $12.6 million, or an average of $30.52 per share under the September 16, 2019 plan. Repurchase activity was suspended in March of 2020 due to the impact of the COVID-19 pandemic. The specific timing, price and quantity of repurchases will be at our discretion and will depend on a variety of factors, including general market conditions, the trading price of common stock, legal and contractual requirements, applicable securities laws and S&T's financial performance. The repurchase plan does not obligate us to repurchase any particular number of shares.
