	us-gaap	Loss Contingency Disclosures LossContingencyDisclosures	LOSS CONTINGENCIESLoss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are any such matters that will have a material effect on the consolidated financial statements that are not currently accrued for. However, in light of the uncertainties inherent in these matters, it is possible that the ultimate resolution may have a material adverse effect on Customers’ results of operations for a particular period, and future changes in circumstances or additional information could result in accruals or resolution in excess of established accruals, which could adversely affect Customers’ results of operations, potentially materially.
