Summary of Equity-Based Compensation Plans with Grants Outstanding

The following table provides a summary of each of the Company’s equity-based compensation plans for any plan with grants outstanding at December 31, 2017:

Equity-Based Compensation Plans	Shares Authorized	Options/RSUs Outstanding	Shares Available to Issue
1998 Management Long-Term Stock Option Plan	1,000	6	—
2000 Broadly-Based Stock Option Plan	2,000	89	—
2010 Equity Incentive Plan (1)	700	218	38
2014 Equity Incentive Plan (2)	950	613	276

(1) During 2010, the Company’s shareholders approved the 2010 Equity Incentive Plan (the “2010 Plan”). The 2010 Plan authorizes the Company to issue Options and RSUs to key management employees, including executive officers and Board members.  Of the 700 aggregate shares available to issue, up to 240 may be granted in the form of RSUs.  There were 208 Options and 10 RSUs outstanding as of December 31, 2017. Of the 38 shares available to be issued under the 2010 Plan, substantially all may be granted as RSUs.

(2) During 2014, the Company’s shareholders approved the 2014 Equity Incentive Plan (the “2014 Plan”). The 2014 Plan authorizes the Company to issue Options to key management employees, including executive officers and Board members. Option grants under the 2014 Plan are generally divided such that vesting for 50% of the Option grant is solely contingent upon continued employment or continued service as a Director, while vesting for the remaining 50% of the Option grant is contingent upon both continued employment or service as a Director and the achievement of a performance metric.  The performance metric is based on the Company’s return on capital performance relative to a peer group during a specified three year period based on the date of Option grant, with the initial performance period being 2014 through 2016.  Based on the Company's return on capital performance, the initial performance period metric was met. Future vesting of Option grants subject to the initial performance period are subject only to continued employment or continued service as a director. Options granted under the 2014 Plan vest annually over four years in 25% increments beginning on December 31, 2016, or later based on the date of grant.
