SIGNIFICANT GROUP CONCENTRATIONS OF CREDIT RISK
Although we have a diversified loan portfolio, a significant portion of our loans are collateralized by real estate.  Repayment of these loans is in part dependent upon the economic conditions in the market area.  See “Item 1.  Business – Market Area.” Part of the risk associated with real estate loans has been mitigated since 31.6% of this group represents loans collateralized by residential dwellings that are primarily owner occupied.  Losses on this type of loan have historically been less than those on speculative properties.  Many of the remaining real estate loans are collateralized primarily with non owner-occupied commercial real estate. 
 The MBS we hold consist exclusively of U.S. agency pass-through securities which are either directly or indirectly backed by the full faith and credit of the United States Government or guaranteed by GSEs.  The GNMA mortgage-backed securities are backed by the full faith and credit of the United States Government. The Fannie Mae and Freddie Mac U.S. agency GSE guaranteed MBS are not backed by the full faith and credit of the United States government.
