Commitments and Contingencies Disclosure [Abstract] |
Legal Matters |
16. | Legal Matters
We are involved in litigation and regulatory proceedings incidental to our business that are in various procedural stages. We believe that the accruals we have recorded for probable and reasonably estimable losses with respect to these proceedings are adequate and that, as of February 28, 2018, it was not reasonably possible that an additional material loss had been incurred in an amount in excess of the estimated amounts already recognized or disclosed in our consolidated financial statements. We evaluate our accruals for litigation and regulatory proceedings at least quarterly and, as appropriate, adjust them to reflect (a) the facts and circumstances known to us at the time, including information regarding negotiations, settlements, rulings and other relevant events and developments; (b) the advice and analyses of counsel; and (c) the assumptions and judgment of management. Similar factors and considerations are used in establishing new accruals for proceedings as to which losses have become probable and reasonably estimable at the time an evaluation is made. Based on our experience, we believe that the amounts that may be claimed or alleged against us in these proceedings are not a meaningful indicator of our potential liability. The outcome of any of these proceedings, including the defense and other litigation-related costs and expenses we may incur, however, is inherently uncertain and could differ significantly from the estimate reflected in a related accrual, if made. Therefore, it is possible that the ultimate outcome of any proceeding, if in excess of a related accrual or if an accrual had not been made, could be material to our consolidated financial statements.
