5. HELD-TO-MATURITY Securities

These are debt securities that Huntington has the intent and ability to hold until maturity. The debt securities are carried at amortized cost and adjusted for amortization of premiums and accretion of discounts using the interest method.

Huntington transferred $469.1 million of federal agencies, mortgage-backed securities from the available-for-sale securities portfolio to the held-to-maturity securities portfolio in the 2011 second quarter. The securities were reclassified at fair value at the date of transfer. At the time of the transfer, $0.5 million of unrealized net gains were recognized in OCI. The amounts in OCI will be recognized in earnings over the remaining life of the securities as an offset to the adjustment of yield in a manner consistent with the amortization of the premium on the same transferred securities, resulting in an immaterial impact on net income.

During 2011, Huntington purchased additional federal agencies, mortgage-backed securities, which were classified directly into the held-to-maturity portfolio.

Listed below are the contractual maturities (under 1 year, 1-5 years, 6-10 years, and over 10 years) of held-to-maturity securities at September 30, 2011. There were no securities classified as held-to-maturity at December 31, 2010 or September 30, 2010.
