Less: Income tax benefit1,491 1,008 
Unrealized holding losses, net of tax(4,990)(3,373)
The unrealized losses are associated with the Company’s investments in mortgage-backed securities issued by GNMA and were caused by interest rate increases (See Note 4). The contractual cash flows of these securities are guaranteed by an agency of the U.S. government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost bases of the Company's investments. The Company does not intend to sell the investments and it is not likely that the Company will be required to sell the investments before recovery of their amortized cost bases.
The unrealized losses, net of unrealized gains, associated with the Company's available-for-sale debt securities are reported as a separate component of Accumulated other comprehensive loss on the accompanying Consolidated Balance Sheets.
