Security Impairment

Huntington evaluates the held-to-maturity securities portfolio on a quarterly basis for impairment. Impairment would exist when the present value of the expected cash flows is not sufficient to recover the entire amortized cost basis at the balance sheet date. Under these circumstances, any impairment would be recognized in earnings. As of March 31, 2015, Management has evaluated held-to-maturity securities with unrealized losses for impairment and concluded no OTTI is required.
