Contingencies [Abstract]
Contingencies	1Note 12. Contingencies The nature of the Corporation’s business generates a certain amount of litigation. We establish accruals for legal proceedings when information related to the loss contingencies represented by those matters indicates both that a loss is probably and the amount of the loss can be reasonably estimated. When we are able to do so, we also determine estimates of possible losses, whether in excess of any accrued liability or where there is no accrued liability. These assessments are based on our analysis of currently available information and are subject to significant judgment and a variety of assumptions and uncertainties. As new information is obtained, we may change our assessments and, as a result, take or adjust the amounts of our accruals and change our estimates of possible losses or ranges of possible losses. Due to the inherent subjectivity of the assessments and the unpredictability of outcomes of legal proceedings, any amounts that may be accrued or included in estimates of possible losses or ranges of possible losses may not represent the actual loss to the Corporation from any legal proceeding. Our exposure and ultimate losses may be higher, possibly significantly higher, than amounts we may accrue or amounts we may estimate. In management’s opinion, we do not anticipate, at the present time, that the ultimate aggregate liability, if any, arising out of all litigation to which the Corporation is a party will have a material adverse effect on our financial position. We cannot now determine, however, whether or not any claim asserted against us, other than the Kalan case described below, will have a material adverse effect on our results of operations in any future reporting period, which will depend on, amount other things, the amount of loss resulting from the claim and the amount of income otherwise reported for the reporting period. Thus, at March 31, 2018, we are unable to provide an evaluation of the likelihood of an unfavorable outcome or an estimate of the amount or range of potential loss with respect to such other matters and, accordingly, have not yet established any specific accrual for such other matters.

The settlement agreements provide for the Bank to make a settlement payment of $10 million in full and final settlement of all claims that the named plaintiffs and members of the settlement class have brought or could have brought against F&M Trust.

On April 12, 2018, the court entered an order setting a hearing on the motion for preliminary approval for May 4, 2018.

1Note 12. Contingencies

The nature of the Corporation’s business generates a certain amount of litigation.

We establish accruals for legal proceedings when information related to the loss contingencies represented by those matters indicates both that a loss is probably and the amount of the loss can be reasonably estimated. When we are able to do so, we also determine estimates of possible losses, whether in excess of any accrued liability or where there is no accrued liability.

These assessments are based on our analysis of currently available information and are subject to significant judgment and a variety of assumptions and uncertainties. As new information is obtained, we may change our assessments and, as a result, take or adjust the amounts of our accruals and change our estimates of possible losses or ranges of possible losses. Due to the inherent subjectivity of the assessments and the unpredictability of outcomes of legal proceedings, any amounts that may be accrued or included in estimates of possible losses or ranges of possible losses may not represent the actual loss to the Corporation from any legal proceeding. Our exposure and ultimate losses may be higher, possibly significantly higher, than amounts we may accrue or amounts we may estimate.

In management’s opinion, we do not anticipate, at the present time, that the ultimate aggregate liability, if any, arising out of all litigation to which the Corporation is a party will have a material adverse effect on our financial position. We cannot now determine, however, whether or not any claim asserted against us, other than the Kalan case described below, will have a material adverse effect on our results of operations in any future reporting period, which will depend on, amount other things, the amount of loss resulting from the claim and the amount of income otherwise reported for the reporting period. Thus, at March 31, 2018, we are unable to provide an evaluation of the likelihood of an unfavorable outcome or an estimate of the amount or range of potential loss with respect to such other matters and, accordingly, have not yet established any specific accrual for such other matters.

No material proceedings are pending or are known to be threatened or contemplated against us by governmental authorities.
