Barclays Plc and Atlas SP Partners are among Wall Street firms that helped arrange more than £2 billion ($2.7 billion) of loans to a UK mortgage-finance company that has unraveled amid allegations of financial irregularities.
Market Financial Solutions Ltd. , or MFS, collapsed into a UK form of insolvency Wednesday with the judge overseeing the case citing accusations of fraud and double-pledging of assets. Barclays and Atlas, the structured-credit arm of Apollo Global Management Inc., each lent hundreds of millions of dollars while Banco Santander SA and Castlelake LP are also among the lenders, according to people familiar with the matter.
