On May 4, 2022, the stockholders of the Company approved the adoption of the Gibraltar Industries, Inc. Amended and Restated 2016 Stock Plan for Non-Employee Directors ("Non-Employee Directors Plan") which increases the total number of shares for issuance by the Company thereunder from 100,000 shares to 200,000 shares, allows the Company to grant awards of shares of the Company's common stock to current 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.

On May 4, 2018, the stockholders of the Company approved the adoption of the Gibraltar Industries, Inc. 2018 Equity Incentive Plan (the "2018 Plan"). The 2018 Plan provides for the issuance of up to 1,000,000 shares of common stock and supplements the remaining shares available for issuance under the Gibraltar Industries, Inc. 2015 Equity Incentive Plan (the "2015 Plan"). Both the 2018 Plan and the 2015 Plan allow the Company to grant equity-based incentive compensation awards, in the form of non-qualified options, restricted shares, restricted stock units, performance shares, performance stock units, and stock rights to eligible participants.

The following table sets forth the number of equity-based awards granted during the three months ended March 31, which will convert to shares upon vesting, along with the weighted average grant date fair values:


	2023			2022
Awards	Number of Awards	Weighted Average Grant Date Fair Value		Number of Awards (2)	Weighted Average Grant Date Fair Value
Performance stock units (1)	81,611	$	53.44	108,464	$	47.00
Restricted stock units	46,646	$	53.44	58,958	$	47.00

(1) The Company’s performance stock units (“PSUs”) represent shares granted for which the final number of shares earned depends on financial performance. The number of shares to be issued may vary between 0% and 200% of the number of PSUs granted depending on the relative achievement to targeted thresholds. The Company's PSUs with a financial performance condition are based on the Company’s return on invested capital (“ROIC”) over a one-year performance period.

(2) PSUs granted in the first quarter of 2022 includes 5,653 units that were forfeited in the first quarter of 2023 and 62,201 units that will be converted to shares and issued to recipients in the first quarter of 2025 at 60.5% of the target amount granted, based on the Company's actual ROIC compared to ROIC target for the performance period ended December 31, 2022.

The Company's equity-based awards that are settled in cash are the awards under the Management Stock Purchase Plan (the “MSPP”) which is authorized under the Company's equity incentive plans. The MSPP provides participants the ability to defer a portion of their compensation, convertible to unrestricted investments, restricted stock units, or a combination of both, or defer a portion of their directors’ fees, convertible to restricted stock units. 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.

The deferrals and related company match are credited to an account that represents a share-based liability. The portion of the account deferred to unrestricted investments is measured at fair market value of the unrestricted investments, and the portion of the account deferred to restricted stock units and company-matching restricted stock units is measured at a 200-day average of the Company’s stock price. The account will be converted to and settled in cash payable to participants upon retirement or a termination of their service to the Company.

Total MSPP liabilities recorded on the consolidated balance sheet as of March 31, 2023 was $15.9 million, of which $2.0 million was included in current accrued expenses and $13.9 million was included in non-current liabilities. Total MSPP liabilities recorded on the consolidated balance sheet as of December 31, 2022 was $15.4 million, of which $2.3 million was included in current accrued expenses and $13.1 million was included in non-current liabilities. The value of the restricted stock units within the MSPP liability were $13.7 million and $13.4 million at March 31, 2023 and December 31, 2022, respectively.
