EQUITY-BASED COMPENSATION

The shareholders of the Company have authorized: (1) the Gibraltar Industries, Inc. 2015 Equity Incentive Plan (the "Plan") that allows the Company to grant equity-based incentive compensation awards, in the form of options, restricted shares, restricted units, performance shares, and performance stock units, to eligible participants; and (2) the Gibraltar Industries, Inc. 2016 Stock Plan for Non-Employee Directors ("Non-Employee Directors Plan") that allows the Company to grant awards of shares of the Company's common stock to non-employee Directors of the Company and permits the Directors to defer receipt of such shares pursuant to the terms of the Non-Employee Directors Plan.

Performance Stock Units - Settled in Cash

The Company awarded performance stock units ("PSUs") that will convert to cash after three years based upon a one year performance period. The cost of these awards is recognized over the requisite vesting period.

During the 2016 performance period, the participants earned an aggregate of 256,000 PSUs, representing 200% the targeted 2016 award of 128,000. This award will convert to cash payable in the first quarter of 2019.

Management Stock Purchase Plan

The Management Stock Purchase Plan ("MSPP") provides participants the ability to defer a portion of their compensation or Directors’ fees, which deferral is converted to restricted stock units, and credited to an account. Employees eligible to defer a portion of their compensation also receive a company-matching award in restricted stock units equal to a percentage of their compensation. Directors do not receive any company-matching on amounts deferred. The account represents a share-based liability that is converted to and settled in cash payable to participants upon retirement or a termination of their service to the Company.
