A new accounting standard could change more than the banking industry's handling of loan losses.

A number of banks are starting to warn the Current Expected Credit Loss standard proposed by the Financial Accounting Standards Board could force them to rethink the terms and conditions of certain loans.

Wells Fargo is “studying whether we will change the types of products we offer” as a result of CECL, Mario Mastrantoni, director of accounting policy at the San Francisco banking giant, said during a recent roundtable hosted by FASB at its Norwalk, Conn., headquarters.

“Concerns about the impact on lending are real,” Mastrantoni added. "I know our senior management is concerned.”

While a Wells spokeswoman did not respond to a request for additional comment, the remarks are noteworthy because they provide a glimpse into the discussions other banks are likely having as CECL's implementation deadline looms. Privately held banks must adopt CECL by Jan. 1, 2021. Adoption by credit unions will happen a year later.

Wells Fargo and other publicly traded banks are scheduled to convert in less than a year.
