First Banks Inc. of St. Louis agreed to acquire Pittsfield Community Bancorp Inc. in Illinois.
The $9.2 billion-asset First Banks signed the deal in December but did not announce it until last week.
Allen H. Blake, First Banks' president and chief executive officer, said that his company had not previously disclosed the deal because it was so small.
Pittsfield Community has $17 million of assets and two branches.
The deal is expected to close next quarter. Mr. Blake did not say how much First Banks would pay.
First Banks plans to sell Pittsfield Community's office in Mount Sterling to the $48 million-asset Beardstown Savings. That deal was signed March 7.
Also, First Banks also plans to merge its own Pittsfield branch with Pittsfield Community's branch there.
