We continue to focus on adding talent to our organization , especially in areas that will grow revenue . Our fee income business lines delivered strong results lead by our mortgage division with mortgage originations exceeding $ 500 million for the quarter . Retirement and benefits revenue increased over 8 % during the quarter as the integration of our recent acquisition of RPS / 24HourFlex continues to perform as planned . Wealth management revenue grew almost 4 % during the quarter as our advisors remained focused on proactive outreach to clients in our local footprint and nationwide . On the banking side , we continued to see stable credit quality , strengthening local economies and low levels of loan deferrals during the quarter . Our reserve levels remain very robust at over 2 % of loans ( excluding Paycheck Protection Program , or PPP ) . In addition , we saw a modest uptick in commercial line utilization , solid loan demand , and building pipelines . In addition to our emphases on growth , we are also focused on technology investments . Over the last several years , we have invested in new technology for both our business and consumer clients , and now , we continue to develop robotics and other automation processes to improve our efficiency and support our ongoing growth initiatives . Today , we have 26 automated process robots in production across our organization . Many of these robots were developed within the last year to support unprecedented mortgage volume and new loans under the PPP . Furthermore , we recently became one of 66 limited partners in a fund focused on the acceleration of technology for community banks . We believe this is a valued partnership that will allow us to stay abreast of emerging technology trends in the community banking landscape . Also in the first quarter , we redeemed our previously issued subordinated debt with a rate of 5.75 % and refinanced with subordinated debt issued to the Bank of North Dakota with an initial fixed annual rate of 3.50 % . Our capital levels remain strong and we believe we have strong capital return potential with our proven ability to execute accretive M & A , our history of strong dividend yields , and our newly approved stock buyback plan .
