We are also working with commercial loan customers that may need payment deferrals or other accommodations to keep their loans out of default through the COVID-19 pandemic. As of June 30, 2020, we have 157 payment deferrals on commercial loans with a total principal balance of $262.4 million, or 13.3%, of total commercial loans, of which $201.3 million are loans included in an at-risk sector.

The residential loan and consumer loan portfolios have not experienced significant credit quality deterioration as of June 30, 2020; however, we anticipate that the COVID-19 pandemic will result in increases in delinquencies, charge-offs and loan modifications in these portfolios through the remainder of the year. As of June 30, 2020, we had 172 payment deferrals on residential mortgage loans with a total principal balance of $52.7 million, or 4.6% of total residential loans, and 664 payment deferrals on consumer loans with a total principal balance of $15.9 million, or 4.5%, of total consumer loans.
