American Savings will buy 16 more branch offices.

The nation’s second-largest savings and loan, based in Stockton, said it will acquire the branches from Sears Savings Bank. Terms of the deal were not disclosed. Sears said it wants to scale back its retail banking operations to the San Francisco Bay Area and Southern California. The 16 Sears branches, which have a total of $580 million in deposits, are scattered in small to medium-size towns across the state. The sale is subject to regulatory approval.
