As part of Valley's dividend reinvestment plan (DRIP), Valley may issue authorized and previously unissued or treasury shares of Valley common stock for purchases.

Shares purchased under this plan were issued directly from Valley. During 2017, 2016 and 2015, 713 thousand, 554 thousand, and 713 thousand common shares, respectively, were reissued from treasury stock or issued from authorized common shares under the DRIP for net proceeds totaling $8.2 million, $5.2 million and $7.0 million, respectively.

The ten-year warrant to purchase up to 489 thousand of Valley common shares has an exercise price of $11.30 per share, and is exercisable on a net exercise basis.

During 2010, the U.S. Treasury sold the warrant shares individually through a public auction, in which Valley did not receive any of the proceeds. The warrants are currently traded on the New York Stock Exchange under the ticker symbol “VLY WS”. Each warrant entitles the holder to purchase approximately 1.103 Valley common shares at $16.12 per share and is exercisable through the expiration date of November 14, 2018. Repurchase Plan. In 2007, Valley’s Board of Directors approved the repurchase of up to $4.7 million of common shares. Purchases of Valley’s common shares may be made from time to time in the open market or in privately negotiated transactions generally not exceeding prevailing market prices. Repurchased shares are held in treasury and are expected to be used for general corporate purposes or issued under the dividend reinvestment plan. Under the repurchase plan, Valley made no purchases of its outstanding shares during the years ended December 31, 2017, 2016 and 2015. Other Stock Repurchases.
