Mortgage-Bond Math Means Everyone Is a Winner: Jonathan Weil

There’s no reason to think MBIA Inc. and Bank of America Corp. are conspiring to make the Big Four accounting firm PricewaterhouseCoopers LLP look foolish. They couldn’t have done a better job, though, if they tried.

As the outside auditor for both companies, it’s PwC’s job to make sure each presents its financial results fairly. The strange part here is that MBIA and Bank of America have taken dueling accounting positions when it comes to some soured mortgage bonds that MBIA insured during the housing boom. PwC meanwhile is letting both companies’ approaches stand.
