Dividends Our dividend policy and the payment of cash dividends under that policy are subject to the Board of Director’s continuing determination that the dividend policy and the declaration of dividends are in the best interest of the Company’s shareholders.

Payment of dividends is also subject to the continuing compliance with our financial covenants under our Credit Facility. During 2016, 2015 and 2014, our Board declared the following quarterly cash dividends on our common stock:

On March 6, 2017, our Board of Directors declared a quarterly dividend of $0.075 per share. The dividend will be paid on March 31, 2017 to all shareholders of record at the close of business on March 17, 2017. Effective August 13, 2012, the Company implemented a Dividend Reinvestment Plan (the “Plan”), under which the Company may issue up to 750,000 shares of common stock. The Plan provides a way for interested shareholders to increase their holdings in our common stock. Participation in the Plan is strictly voluntary and is open only to existing shareholders. The Plan has had limited participation. Share-Based Compensation The 2007 Equity Incentive Plan (the “2007 Plan”) was approved by shareholders on May 23, 2007 and replaced the 1997 Stock Option Plan (the “1997 Plan”). The 2007 Plan permits the granting of stock options and stock awards which are granted at a price equal to or greater than the fair market value of the Company’s common stock at the date of the grant. Stock options granted to employees generally vest equally over a period of three to five years from the date of the grant. Stock awards granted to employees generally vest equally over a period of four to five years from the date of the grant. During 2016, approximately 105,000 stock options and 267,000 restricted stock awards were granted to plan participants under the 2007 Plan. During 2015, approximately 286,000 stock options and 323,000 restricted stock awards were granted to plan participants under the 2007 Plan. There are approximately 53,000 performance-based awards outstanding at December 31, 2016 and December 31, 2015. The remainder of the awards outstanding are service based awards that vest over a service period. The number of shares reserved for issuance under the 2007 Plan is 3,300,000, of which approximately 414,000 shares were available for future grant as of December 31, 2016. Share-based compensation expense for stock options and restricted stock awards under these plans of $2.2 million, $1.9 million and $1.7 million was recorded in the years ended December 31, 2016, 2015 and 2014, respectively. The tax benefit related to share based compensation expense was $0.2 million, zero, and $0.2 million in 2016, 2015 and 2014, respectively. Employee Stock Purchase Plan The 2009 Employee Stock Purchase Plan (“ESPP”) was approved by shareholders on May 21, 2009. The ESPP is administered by the Compensation Committee. The aggregate maximum number of shares of the Company’s common stock that may be granted under the ESPP is 1,500,000 shares over the ten-year term of the ESPP, subject to adjustment in the event there is a reorganization, merger, consolidation, recapitalization, reclassification, stock split-up, or similar transaction with respect to the common stock. The ESPP allows employees to purchase shares of common stock at a 15% discount from market price and pay for the shares through payroll deductions. Eligible employees can enter the plan at specific “offering dates” that occur in six month intervals. The Company recognized employee stock purchase plan expense of $71,000, $54,000 and $19,000 during the years ended December 31, 2016, 2015 and 2014, respectively. Employees’ Stock Ownership Trust The Company sponsors an employee stock ownership plan under which it may make discretionary contributions to the trust, either in cash or in shares of Company common stock, for certain salaried employees of Met-Pro in the United States who are eligible to participate in the Plan. There were no contributions to the Employees’ Stock Ownership Trust for the years ended December 31, 2016, 2015 and 2014. All shares are considered to be allocated to participants or to be released for allocation to participants, and are included in the earnings per share computations. Stock Options and Restricted Awards The weighted-average fair value of stock options granted during 2016, 2015, and 2014 was estimated at $2.07, $4.35 and $6.48 per option, respectively, using the Black-Scholes option-pricing model based on the following assumptions: Expected Volatility: The Company utilizes a volatility factor based on the Company’s historical stock prices for a period of time equal to the expected term of the stock option utilizing weekly price observations. For 2016, 2015, and 2014, the Company utilized weighted-average volatility factors of 39%, 44% and 55%, respectively. Expected Term: Due to limited historical exercise data, the Company utilizes the simplified method of determining the expected term based on the vesting schedules and terms of the stock options. For 2016, 2015 and 2014, the Company utilized weighted-average expected term factors of 6.5 years, 6.3 years and 6.3 years, respectively. Risk-Free Interest Rate: The risk-free interest rate factor utilized is based upon the implied yields currently available on U.S. Treasury zero-coupon issues over the expected term of the stock options. For 2016, 2015 and 2014, the Company utilized a weighted-average risk-free interest rate factor of 2.1%, 1.9% and 2.2%, respectively. Expected Dividends: The Company utilized a weighted average expected dividend rate of 3.6%, 2.4% and 1.7% to value options granted during 2016, 2015 and 2014, respectively. Information related to all stock options under the 2007 Plan and 1997 Plan for the years ended December 31, 2016, 2015 and 2014 is shown in the tables below:

Information related to all restricted stock awards under the 2007 Plan for the years ended December 31, 2016 is shown in the table below.

The pre-vesting forfeiture estimate is based on historical activity and is reviewed periodically and updated as necessary.

(“Icarus”), a related party, at an exercise price of $9.07 and an expiration date of December 26, 2016. On December 7, 2016, the Company and Icarus entered into an amendment of the warrant agreement pursuant to which the warrants were issued to provide for the cashless exercise of the warrants. During the year ended December 31, 2016, all of the Company’s previously outstanding warrants were exercised and the Company issued 89,640 shares of common stock through a cashless exercise pursuant to such amendment at an effective price of $9.07 per share.
