Working our way through and out of the COVID - 19 pandemic , we were true to our “ Home Town Bank ” motto and helped many people in the communities we serve , while simultaneously achieving meaningful shareholder value and return . ” We not only continued without interruption our long history of paying a meaningful dividend , we also won shareholder approval of a reverse stock split that we believe will improve the company's position in the market by making our stock attractive to a wider audience . At the same time , we also supported food banks , renewed our commitments to distressed neighborhoods , invested in affordable housing programs , aided educational programs , and encouraged savings initiatives . We also continued to assist consumer and commercial customers as they worked their way out of the hardships of the past year and are happy to report that virtually all Trustco Bank borrowers who received pandemic relief are making payments as agreed . Our team is never one to rest on its successes . Our entire management team , from those leading our branches to the heads of our internal departments , are focused on generating new business by reaching an ever - expanding consumer audience with our industry - leading residential mortgage products and developing new relationships with commercial customers who share our forward - looking and success - oriented vision . As always , we pursue these objectives with our trademark efficiency . Page 1
