Legal and Other Proceedings	LEGAL AND OTHER PROCEEDINGS In accordance with the current accounting standards for loss contingencies, we establish reserves for litigation-related matters that arise in the ordinary course of our business activities when it is probable that a loss associated with a claim or proceeding has been incurred and the amount of the loss can be reasonably estimated. Litigation claims and proceedings of all types are subject to many uncertain factors that generally cannot be predicted with assurance. In addition, our defense of litigation claims may result in legal fees, which we expense as incurred.

On April 7, 2015, WSFS Bank received a notice of arbitration and statement of claim (the Claim) from Universitas Education, LLC (Universitas) relating to Christiana Trust acting as “insurance trustee” of the Charter Oak Trust Welfare Benefit Plan (the Trust). The actions underlying the Claim occurred during a period prior to WSFS’ acquisition of Christiana Trust. According to the allegations contained in the Claim, certain life insurance policy benefits paid to an individual claiming/purporting to be a trustee of the Trust were misappropriated by individuals associated with the plan sponsor. None of those individuals, however, were employed by or agents of Christiana Trust or WSFS Bank. It is alleged that Christiana Trust, as insurance trustee, owed a fiduciary duty to the beneficiaries of the Trust and that it breached its fiduciary duty, was negligent, and aided and abetted fraud and theft in connection with the misappropriation of funds. It is further alleged that Universitas was the rightful beneficiary under the Trust of the misappropriated funds, and thus was harmed because it did not receive the death benefits that had been paid over to the purported trustee of the Trust. While the face amounts of the two insurance policies in question total $30 million, Universitas revised its total Claim to assert an alleged loss of approximately $27 million plus costs and interest to date of $27 million. WSFS is vigorously defending itself against the Claim and believes that it has valid factual and legal defenses to the Claim. The evidentiary hearing concluded late in the third quarter of 2017 and post-trial briefing will conclude in late November 2017. It is anticipated that a decision in the arbitration will be rendered during the fourth quarter of 2017 or the first quarter of 2018. WSFS does not believe that the ultimate resolution of the Claim will have a material adverse effect on the Company, but there can be no assurance as to the ultimate outcome. There were no material changes or additions to other significant pending legal or other proceedings involving us other than those arising out of routine operations.
