6. Contingencies

From time to time, we are involved in legal proceedings that we consider to be in the normal course of business. Claimed amounts against us may be substantial but may not bear any reasonable relationship to the merits of the claim or the extent of any real risk of court or arbitral awards. We record accruals for losses related to those matters against us that we consider to be probable and that can be reasonably estimated. Although it is not feasible to predict the outcome of these matters with certainty, it is reasonably possible that some legal proceedings may be disposed of or decided unfavorably to us and in excess of accrued amounts, if any. Based on available information, in the opinion of management, settlements, arbitration awards and final judgments, if any, that are considered probable of being rendered against us in litigation or arbitration in existence at September 30, 2017, and that can be reasonably estimated are either reserved against or would not have a material adverse effect on our financial condition, results of operations or cash flows.
