Segment Disclosures
Segment Disclosures	Note K Segment Disclosures BancShares is a financial holding company headquartered in Raleigh, North Carolina that offers full-service banking through a single wholly-owned banking subsidiary, First-Citizens Bank & Trust Company (FCB), a North Carolina-chartered bank. Prior to January 7, 2011, BancShares also offered full service banking services through another wholly-owned subsidiary, IronStone Bank (ISB), a federally-chartered thrift institution. On January 7, 2011 ISB was legally merged into FCB resulting in a single banking subsidiary of BancShares. Prior to the merger, FCB and ISB were considered to be distinct operating segments. As a result of the merger and various organizational changes resulting from the merger, there is no longer a focus on the discrete financial measures of each entity. Therefore, BancShares now operates as one reportable segment.
