1) Bank is very well capitalized with TCE + ACL to TCA ratio at 10.2%, which would rank us as the 32nd best capitalized publicly traded bank in the United States 2) Current cash dividend is at $0.22 per quarter which is a 43% payout ratio of the current quarter’s earnings of $0.51. The Company has paid out a cash dividend for 151 consecutive quarters and believes the current dividend is reasonable based on expected earnings going forward but the Board will act in the long-term interest of shareholders if earnings diminish substantially as a result of COVID-19 credit costs. 3) The Company's ongoing share repurchase program remains in place; however, management believes that it is prudent to pause repurchases for the time being as it continues to evaluate the extent of the COVID-19 related economic impact.
