Security Pacific said it is looking at more banks.

A Security Pacific spokeswoman declined to comment on published reports that the bank is about to make an offer for Oregon Bank, the state’s third largest. “We are looking at financial institutions in the Pacific Northwest as we are in the West, but we can’t identify them,” she said. A spokeswoman for Oregon Bank also declined comment. Security Pacific on Tuesday agreed to buy Nevada National Bancorp as part of the bank’s expansion in the West.
