April 22 (Reuters) - Bank holding company Iberiabank Corp (IBKC.O) posted a 32 percent drop in first-quarter profit, hurt by a charge related to its repayment of Treasury funds, but said provision for loan losses halved sequentially.

The company earned $9.1 million, or 36 cents a share for the quarter, compared with $13.4 million, or $1.02 a share, a year earlier.

Income available to common shareholders was $5.6 million for the period.

Iberiabank, the first U.S. bank to complete repayment of the capital it received under the Treasury's Troubled Assets Relief Program, said it incurred a charge of $2.2 million in the form of an accelerated deemed dividend.

The company's tangible common equity ratio, a measure of capital strength closely watched by investors now, improved sequentially by 27 basis points to 7.51 percent at March 31.
