[1] It is reasonably possible that there could be a change in the amount of unrecognized tax benefits within the next 12 months due to activities of the Internal Revenue Service ("IRS") or other taxing authorities, including proposed assessments of additional taxes, possible settlement of audit issues, or the expiration of applicable statutes of limitations. We estimate that the range of the possible change in unrecognized tax benefits within the next 12 months may be a decrease of approximately zero to $195.0 million, exclusive of penalties and interest.
