Commitments and Contingencies
Guarantees of Indebtedness
The payments of principal and interest on our senior notes are guaranteed by AFSI. As of September 30, 2013 and December 31, 2012, the par value of our senior notes was $4.0 billion and $1.5 billion. See Note 17 - "Guarantor Consolidating Financial Statements" for further discussion.
Other Administrative Tax Matters
We accrue non-income tax liabilities for contingencies when management believes that a loss is probable and the amounts can be reasonably estimated, while contingent gains are recognized only when realized. In the event any losses are sustained in excess of accruals, they will be charged against income at that time.
In evaluating indirect tax matters, we take into consideration factors such as our historical experience with matters of similar nature, specific facts and circumstances, and the likelihood of prevailing. We reevaluate and update our accruals as matters progress over time. It is reasonably possible that some of the matters for which accruals have not been established could be decided unfavorably to us and could require us to make expenditures for which we estimate the aggregate risk to be a range of up to $32 million.
