Wheeling, W.Va.-based WesBanco Inc.'s board authorized the company to purchase up to an additional 1.7 million common shares, representing about 2.5% of its outstanding shares, from time to time.

The buyback plan does not have an expiration date. Repurchases may be funded from one or a combination of cash balances and other liquidity sources.

The amount is in addition to the share repurchase plan authorized in October 2015, which has about 885,000 shares remaining for repurchase and will continue to be used until the authorization is completed.
