GULFPORT, Mississippi — Hancock Holding Co.’s third-quarter profit slipped to $41.2 million, or 52 cents per share, compared to $46.6 million, or 56 cents a share, a year ago.

The decline was mainly related to a $13 million decrease in purchase accounting, or placing the fair value on the assets and liabilities of acquisitions.

President and Chief Executive Officer John M. Harrison said Hancock is growing despite the current energy downturn, which the company continues to believe is manageable.

“This quarter we added another $5 million, or almost a nickel of earnings, to the provision to build the energy reserve and remain confident that any credit losses we see today from the low oil prices are reserved for and should not be significant,” Harrison said.
