American Savings agreed to buy 13 more offices.

The large savings and loan said it will acquire the 13 branch offices, which are located in Northern California, as well as deposits of about $570 million from Great Western Savings. The total deposits being sold also include accounts at two additional Great Western branch offices in Paradise and Yuba City, Calif., both of which will be closed, a Great Western spokesman said. Terms of the proposed sale were not announced. If approved by regulatory authorities, the sale will give American 169 branch offices statewide.
