Will the Cost of Float Adjusted for Favourable Tax Attributes Be Lower Than What Berkshire Would Have Paid?

Berkshire received a 10.2 billion retroactive premium from AIG early last year. If the upperly revised estimate of ultimate claims proves to be correct, will the cost of float adjusted for favorable tax attributes likely be lower or higher than what Berkshire would have paid to borrow 10 billion for a similar duration? Well, we certainly go in with the idea that it will be lower. There's also a lot of financial engineering that's raised leverage even in the capital of the 10 businesses.
