Wells Fargo & Co., the second-biggest US home lender, said its fourth-quarter loss was wider than first reported because of additional costs tied to securities holdings.

The bank recorded a pretax charge of $328.4 million related to holdings of perpetual preferred securities, the San Francisco-based company said yesterday in a statement. That increased the quarterly loss reported last month to $2.73 billion, or 84 cents a share, from $2.55 billion, or 79 cents.Wells Fargo stock lost 70 cents to $16.80 yesterday on the New York Stock Exchange, and has tumbled 43 percent this year.
