[1] (3) During the fourth quarter of 2019, the Company's board of directors announced a 5% increase to the quarterly dividend rate to $0.225 per share from $0.215 per share, beginning with the dividend payable in the first quarter of 2020. On February 28, 2020, the Company’s board of directors declared a quarterly cash dividend of $0.225 per share of common stock. The dividend was payable on April 16, 2020 to shareholders of record on April 2, 2020. In April 2020, subsequent to the payment of the dividend and in light of uncertainty resulting from the COVID-19 pandemic, we suspended future, undeclared dividends. During 2020 and 2021, accumulated dividends were paid to certain shareholders upon vesting of certain performance vested restricted stock units ("PVRSU") which are captured in Share-based payment activity. On May 7, 2021 and September 9, 2021, the Company's board of directors declared a quarterly cash dividend of $0.225 per share of common stock. On December 6, 2021, the Company's board of directors approved a 6% increase in the quarterly cash dividend and declared a quarterly cash dividend of $0.2375 per share of common stock.
