Thanks to Anonymous, our attention is directed to BankUnited's visit to the confessional. Somehow loan loss reserves went from $8-10MM in pre-release to $19.1MM in the official release. It's the sort of thing that can happen to anyone, you know.

Because we were talking about Option ARMs yesterday, I thought I'd share this bit:

As of Sept. 30, 2007, BankUnited’s option-ARM balances totaled $7.6 billion, which represented 70% of the residential loan portfolio and 60% of the total loan portfolio. For the quarter ended Sept. 30, 2007, the growth in negative amortization was $48 million, compared to $46.4 million for the quarter ended June 30, 2007. Of the $7.6 billion in option-ARM balances, $6.5 billion had negative amortization of $270 million, or 3.55%, of the option-ARM portfolio.

If I'm reading that correctly, it means that 87% of the OA portfolio, by balance, is negatively amortizing, and the total amount of negative amortization is 4.1%. Without the weighted average age of the loans, there is no way to calculate an annual rate of negative amortization. I would be surprised if the average age is more than 24 months, which would produce a rate of around 2.00% annual average balance growth.
