[1] Amount represents the fair value of one TRUP that was deemed to have credit-related OTTI at December 31, 2011. At December 31, 2011, four additional TRUPS with an aggregate fair value of $1,427 were not carried at fair value despite previously meeting the OTTI criteria. Under ASC 320-10-65, these held-to-maturity securities are only carried at fair value in the event that they incur additional credit-related impairment at period end, which did not occur at December 31, 2011. Losses for the period represent the total OTTI recognized on three TRUPS (credit or non-credit related) during the period.

[2] Amount represents charge-offs recognized on impaired loans during the three-month and six-month periods ended June 30, 2012.
