LONDON--Espírito Santo Bank, the Miami arm of failed Portuguese lender Banco Espírito Santo SA, is being sold to Venezuela's Benacerraf banking family in a $10 million deal, the Portuguese bank said Friday.

The agreement, which is still subject to regulatory approval, marks the end of a nine-month effort to find a buyer for the Florida bank after Banco Espírito Santo collapsed amid allegations of fraud in August. The Bank of Portugal that month carved out a good bank called Novo Banco to keep serving retail and corporate customers in countries including Portugal, Spain, Brazil and Venezuela, but left behind a handful of unwanted assets including Espírito Santo Bank.

The move resulted in Espírito Santo Bank customers pulling hundreds of millions of dollars in deposits and brokerage accounts, and the bank was ordered by the Federal Deposit Insurance Corp. in August to find a new owner.

After months of talks with the Benacerrafs, one of Venezuela's oldest banking families, a deal was struck. The Venezuelan family's other holdings include Caracas-based 100% Banco, and it was once part-owner of a U.S. bank through a shareholding in Banco Union CA, now part of Venezuelan lender Banesco. The family patriarch, Salomón Henry Benacerraf, was chairman of Visa International between 1987 and 1994, according to filings.

Espírito Santo Bank, with around $660 million of assets, has just one branch in a skyscraper owned by another bankrupt part of the Espírito Santo group. It caters to wealthy Venezuelans and Brazilians who want to buy Florida condominiums or make investments through its brokerage arm.

For nearly four decades, it had a key role in raising funding for the various companies of Portugal's wealthy Espírito Santo family, who also sat on its board. In 2012, it was censured by the Financial Industry Regulatory Authority for misrepresenting the risk of Espírito Santo group commercial paper it sold to brokerage customers.

Espírito Santo Bank cut ties with the Portuguese family last year, but several legal and regulatory hurdles still stood in the way of Thursday's sale agreement.

A year-long investigation by multiple agencies over a series of transactions with ES Bank Panama, an Espírito Santo affiliate, cumulated in a February consent order from the FDIC that was made public last week. In it, Espírito Santo Bank agreed to improve its anti-money-laundering controls and compliance with the U.S. Bank Secrecy Act.

Separately, in December, Espírito Santo Bank agreed to pay $8 million to resolve a suit by the liquidator of a bankrupt Brazilian bank over alleged money laundering.

The proceeds from the planned sale will go to Banco Espírito Santo, where a Bank of Portugal lawyer has been put in charge of the Portuguese bank's liquidation. The bank said that besides the $10 million, it will receive $5 million minus any amount spent in pending legal settlements. The bank's other assets, a stake in BES's Angolan arm and in a Libyan bank, have already been liquidated.

The good bank, Novo Banco, is close to being sold after a list of potential buyers was cut to five this month.
