As of June 30, 2018, the Board of Directors has authorized the Company to repurchase up to an additional 4,874,000 shares of Polaris stock. The repurchase of any or all such shares authorized for repurchase will be governed by applicable SEC rules and dependent on management’s assessment of market conditions.

On July 25, 2018, the Polaris Board of Directors declared a regular cash dividend of $0.60 per share payable on September 17, 2018 to holders of record of such shares at the close of business on August 31, 2018.

Net income per share

Basic income per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during each period, including shares earned under the Deferred Compensation Plan for Directors (“Director Plan”) and the ESOP and deferred stock units under the 2007 Omnibus Incentive Plan (“Omnibus Plan”). Diluted income per share is computed under the treasury stock method and is calculated to compute the dilutive effect of outstanding stock options and certain shares issued under the Omnibus Plan. A reconciliation of these amounts is as follows (in thousands):



	Three months ended June 30,		Six months ended June 30,
	2018	2017	2018	2017
Weighted average number of common shares outstanding	62,913	62,638	62,982	62,756
Director Plan and deferred stock units	177	157	171	151
ESOP	82	100	85	105
Common shares outstanding—basic	63,172	62,895	63,238	63,012
Dilutive effect of Omnibus Plan	1,714	912	1,814	958
Common and potential common shares outstanding—diluted	64,886	63,807	65,052	63,970

During the three and six months ended June 30, 2018, the number of options that were not included in the computation of diluted income per share because the option exercise price was greater than the market price, and therefore, the effect would have been anti-dilutive, were 1,812,000 and 1,677,000, respectively, compared to 3,626,000 and 3,398,000 for the same periods in 2017.
