renamed Bank of Hawaii Corporation. Activities on the U.S. Mainland In its first expansion onto the continental United States, BOH as Bancorp Hawaii acquired the Phoenix, Arizona-based First National Bancorp of Arizona with its five-office First National Bank of Arizona subsidiary for an undisclosed amount in 1987. Ten years later, through its First National Bank of Arizona subsidiary, BOH acquired all four Arizona branch offices from Home Savings of America for an undisclosed amount in 1997 and merged those offices into First National while at nearly the same time changed the name of First National to Pacific Century Bank NA. The following year, BOH as Pacific Century Financial Corporation acquired the Encino, California-based CU Bancorp with its California United Bank subsidiary for $183 million in stock and cash. Just shortly after the acquisition was finalized in 1998, California United and its 22 offices in Southern California was merged into Phoenix-based Pacific Century Bank and the headquarters for the newly combined Pacific Century Bank was moved to Encino.
