Don A. Langford, who pleaded guilty this week to two federal crimes related to the collapse of TierOne Bank of Lincoln, was the leader of a team working to resolve problem loans for M&T Bank of Buffalo, New York, until last week.
One of M&T Bank's largest shareholders is Berkshire Hathaway Inc. of Omaha, with about 4.1 percent of its publicly traded shares.
Langford was chief credit officer at TierOne from February 2008 until April 2010, when federal regulators took over the bank because of losses from real estate development loans in other states. He joined M&T Bank later and, a bank spokesman said Wednesday, no longer works there.
Tuesday, Langford pleaded guilty to conspiring with others to deceive regulators and investors about TierOne's financial condition and to giving false information to the federal government. He faces up to 10 years in prison and $500,000 in fines.
A judge is due to accept his plea and sentence him in December, but attorneys said sentencing may be delayed. The federal government could bring charges against other TierOne officers and Langford, who signed a plea deal with prosecutors, could be called to testify.
Federal banking rules prohibit people from working at insured institutions if they have been convicted of "any criminal offense involving dishonesty or a breach of trust." People who have been charged with such crimes can be banned from working for banks.
M&T is one of the 20 largest commercial banks in the nation, with $85 billion in assets and more than 700 branch offices in seven states and the District of Columbia.
