We declared aggregate cash dividends of $0.24 per share of common stock for 2017, 2016 and 2015, respectively. Our Credit Facility and Term Loans have restrictions regarding the maximum amount of cash dividends allowed to be paid. The payment of the above‑referenced cash dividends was in compliance with the Credit Facility and Term Loans.

In October 2017, our Board of Directors approved a new common stock repurchase program which replaced the remainder of the existing program and authorized the purchase of up to $100.0 million in common stock (the “Repurchase Program”). The Repurchase Program does not require a minimum number of shares of common stock to be purchased, has no expiration date and may be suspended or discontinued at any time. As of December 31, 2017, $100.0 million remains available for purchase under the Repurchase Program. The timing and amount of shares of common stock to be repurchased under the Repurchase Program will depend on market conditions, share price, securities law and other legal requirements and factors. Under several of our repurchase programs, we repurchased 1.6 million shares of our common stock for an aggregate value of $70.5 million during 2015, 1.0 million shares of our common stock for an aggregate value of $41.2 million during 2016 and 1.7 million shares of our common stock for an aggregate value of $61.9 million in 2017.

In May 2016, our shareholders approved the 2016 Omnibus Plan (the “2016 Plan”), which replaced our previously adopted 2006 Omnibus Plan, as amended and restated in 2009 (the “2006 Plan”). The 2016 Plan is administered by the Compensation Committee of the Board of Directors (the “Compensation Committee”). The purpose of the 2016 Plan is to (i) attract and retain persons eligible to participate in the 2016 Plan; (ii) motivate participants, by means of appropriate incentives, to achieve long‑range goals; (iii) provide incentive compensation opportunities that are competitive with those of other similar companies; and (iv) further align participants’ interests with those of our other shareholders through compensation that is based on the value of our common stock. The goal is to promote the long‑term financial interest of World Fuel and its subsidiaries, including the growth in value of our equity and enhancement of long‑term shareholder return. The persons eligible to receive awards under the 2016 Plan are our employees, officers, and members of the Board of Directors, or any consultant or other person who performs services for us.

The provisions of the 2016 Plan authorize the grant of stock options which can be “qualified” or “nonqualified” under the Internal Revenue Code of 1986, as amended, restricted stock, RSUs, SSAR Awards, performance shares and performance units and other share‑based awards. The 2016 Plan is unlimited in duration and, in the event of its

termination, the 2016 Plan will remain in effect as long as any awards granted under it remain outstanding. No awards may be granted under the 2016 Plan after May 2026. The term and vesting period of awards granted under the 2016 Plan are established on a per grant basis, but options and SSAR Awards may not remain exercisable after the seven‑year anniversary of the date of grant.

Under the 2016 Plan, 2.5 million shares of common stock are authorized for issuance plus any shares of common stock with respect to awards that were granted under the 2006 Plan but are forfeited or canceled (e.g., due to the recipient's failure to satisfy applicable service or performance conditions) after May 2016. As of December 31, 2017, approximately 2.2 million shares of common stock were subject to outstanding awards under the 2016 and 2006 Plan (assuming maximum achievement of performance goals for restricted stock and target achievement of performance goals for RSUs, where applicable).

(2)As of December 31, 2017, unvested restricted stock will vest between February 2018 and February 2021, unvested RSUs will vest between February 2018 and May 2019 and the outstanding SSAR Awards will expire in March 2019. RSUs granted to non‑employee directors under the 2006 Plan prior to 2011 remain outstanding until the date the non‑employee director ceases, for any reason, to be a member of the Board of Directors.

As discussed in Note 1, we currently use the Black Scholes option pricing model to estimate the fair value of SSAR Awards granted to employees. The weighted average fair value of the SSAR Awards for 2017 was $8.82 and the assumptions used to determine such fair value were as follows: expected term of 4.3 years, volatility of 28.6%, dividend yields of 0.7% and risk-free interest rates of 1.8%. The weighted average fair value of the SSAR Awards for 2016 was $12.32 and the assumptions used to determine such fair value were as follows: expected term of 4.5 years, volatility of 29.8%, dividend yields of 0.5% and risk-free interest rates of 1.2%. The weighted average fair value of the SSAR Awards for 2015 was $14.78 and the assumptions used to determine such fair value were as follows: expected term of 4.3 years, volatility of 30.2%, dividend yields of 0.3% and risk-free interest rates of 1.2%.

As of December 31, 2017, there was $47.4 million of total unrecognized compensation cost related to unvested share-based payment awards, which is included as capital in excess of par value in the accompanying consolidated balance sheets. The unrecognized compensation cost as of December 31, 2017 is expected to be recognized as compensation expense over a weighted average period of 1.4 years as follows (in millions):
