Commitments— In the normal course of business, Wesbanco offers off-balance sheet credit arrangements to enable its customers to meet their financing objectives. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the financial statements. Wesbanco’s exposure to credit losses in the event of non-performance by the other parties to the financial instruments for commitments to extend credit and standby letters of credit is limited to the contractual amount of those instruments. Wesbanco uses the same credit policies in making commitments and conditional obligations as for all other lending. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The allowance for credit losses associated with commitments was $0.9 million and $0.7 million as of December 31, 2019 and 2018, respectively, and is included in other liabilities on the Consolidated Balance Sheets.

Letters of credit are conditional commitments issued by banks to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements, including normal business activities, bond financing and similar transactions. Letters of credit are considered guarantees. The liability associated with letters of credit was $0.2 million as of both December 31, 2019 and 2018.

Contingent obligations to purchase loans funded by other entities include affordable housing plan guarantees, credit card guarantees, loans sold with recourse as well as obligations to the FHLB. Affordable housing plan guarantees are performance guarantees for various building project loans. The guarantee amortizes as the loan balances decrease. Credit card guarantees are credit card balances not owned by Wesbanco, whereby the Bank guarantees the performance of the cardholder.

Contingent Liabilities— Wesbanco is a party to various legal and administrative proceedings and claims. While any litigation contains an element of uncertainty, management does not believe that a material loss related to such proceedings or claims pending or known to be threatened is reasonably possible.
