DebtX, which operates an online marketplace for loans, plans to accept bids starting next month on nearly $1.1 billion in loans tied to First NBC Bank's collapse.

DebtX is overseeing the sale on behalf of the Federal Deposit Insurance Corp., which was named receiver after New Orleans-based First NBC was declared insolvent in April.

On Sept. 12, DebtX plans to accept bids on a $117 million, single-relationship loan pool secured by energy-related assets in Louisiana. Bidding ends Sept. 29.

On Sept. 26, DebtX will accept bids on 17 loan pools totaling about $1 billion. The portfolio includes performing and non-performing loans and consists primarily of commercial and industrial, real estate-backed commercial and industrial, single-family residential, and government-backed loans. Bidding ends Oct. 18.

“The assets in this sale will appeal to investors of all sizes,” said DebtX CEO Kingsley Greenland. “We have already had significant interest in these loans from a wide range of investors and expect active bidding on both dates.”

To participate, investors must register with and be approved by DebtX. To apply, go to DebtX’s registration page and select the FDIC Market Application option.

DebtX announced the transaction in May, calling it one of the largest cash loan sales executed by the FDIC in the past decade.

At nearly $1 billion, First NBC's collapse marked the costliest failure of an American bank since 2010.
