Commitments and Contingencies Disclosure [Abstract]
Contingency	CONTINGENCY On March 28, 2018, the Corporation received a notice of assessment from the Pennsylvania Department of Revenue that reported a sales tax assessment amount of $824 plus interest and penalties of $339 resulting in a total assessed balance of $1,163. The notice of assessment covers the period from January 1, 2013 through July 31, 2016. The Corporation has evaluated the specific items on which sales tax has been assessed in conjunction with its legal counsel and has determined that it is probable that the Corporation has some liability based on a review of the Pennsylvania tax laws that apply to the assessed items. The Corporation’s reasonable estimate of this liability is $96, which has been accrued and previously reported in state and local tax expense in the consolidated statement of income during the year ended December 31, 2018. The remaining balance that has not been accrued relates primarily to sales tax assessments associated with data processing and banking equipment maintenance, which the Corporation’s management and legal counsel have concluded were improperly assessed based on current Pennsylvania sales tax law. The Corporation appealed the notice of assessment to the Pennsylvania Board of Appeals and is awaiting a decision. The ultimate resolution of this matter, which may take in excess of one year, could result in an additional expense up to the total amount assessed.
