Compensation Plans

Note 7 - Compensation Plans

As of June 30, 2021, 3.8 million shares of common stock were available for grant under the Company’s Equity Incentive Compensation Plan (“Equity Plan”). The Company may also grant other types of long-term incentive-based awards, such as cash awards and performance-based cash awards to eligible employees under its compensation plan.

Performance Share Units

The Company has granted performance share units (“PSUs”) to eligible employees as part of its Equity Plan. The number of shares of the Company’s common stock issued to settle PSUs ranges from zero to two times the number of PSUs awarded and is determined based on certain criteria over a three-year performance period. PSUs generally vest on the third anniversary of the date of the grant or upon other triggering events as set forth in the Equity Plan.

For PSUs granted in 2018 and 2019, the settlement criteria include a combination of the Company’s Total Shareholder Return (“TSR”) relative to the TSR of certain peer companies and the Company’s cash return on total capital invested (“CRTCI”) relative to the CRTCI of certain peer companies over the associated three-year performance period. In addition to these performance criteria, the award agreements for these grants also stipulate that if the Company’s absolute TSR is negative over the three-year performance period, the maximum number of shares of common stock that can be issued to settle outstanding PSUs is capped at one times the number of PSUs granted on the award date, regardless of the Company’s TSR and CRTCI performance relative to its peer group. The fair values of the PSUs granted in 2018 and 2019 were measured on the applicable grant dates using the GBM Model, with the assumption that the associated CRTCI performance condition will be met at the target amount at the end of the respective performance periods. Compensation expense for PSUs is recognized within general and administrative expense and exploration expense over the vesting periods of the respective awards. As these awards depend on a combination of performance-based settlement criteria and market-based settlement criteria, compensation expense may be adjusted in future periods as the number of units expected to vest increases or decreases based on the Company’s expected CRTCI performance relative to the applicable peer companies.

The Company records compensation expense associated with the issuance of PSUs based on the fair value of the awards as of the date of grant. Total compensation expense recorded for PSUs was $1.3 million and $2.8 million for the three months ended June 30, 2021, and 2020, respectively, and $4.5 million and $5.4 million for the six months ended June 30, 2021, and 2020,

respectively. As of June 30, 2021, there was $3.0 million of total unrecognized compensation expense related to non-vested PSU awards, which is being amortized through 2022. There were no material changes to the outstanding and non-vested PSUs during the six months ended June 30, 2021.

Employee Restricted Stock Units

The Company grants restricted stock units (“RSUs”) to eligible persons as part of its Equity Plan. Each RSU represents a right to receive one share of the Company’s common stock upon settlement of the award at the end of the specified vesting period. RSUs generally vest one-third of the total grant on each anniversary date of the grant over the applicable vesting period or upon other triggering events as set forth in the Equity Plan.

The Company records compensation expense associated with the issuance of RSUs based on the fair value of the awards as of the date of grant. The fair value of an RSU is equal to the closing price of the Company’s common stock on the date of the grant. Compensation expense for RSUs is recognized within general and administrative expense and exploration expense over the vesting periods of the respective awards. Total compensation expense recorded for employee RSUs was $2.1 million and $2.7 million for the three months ended June 30, 2021, and 2020, respectively, and $4.3 million and $5.3 million for the six months ended June 30, 2021, and 2020, respectively. As of June 30, 2021, there was $10.1 million of total unrecognized compensation expense related to non-vested RSU awards, which is being amortized through 2023. There were no material changes to the outstanding and non-vested RSUs during the six months ended June 30, 2021.

Subsequent to June 30, 2021, the Company settled 349,328 RSUs upon the vesting of awards granted in previous years. The Company and all grant participants mutually agreed to net share settle a portion of the awards to cover income and payroll tax withholdings, as provided for in the Equity Plan and applicable award agreements. As a result, the Company issued 250,009 net shares of common stock upon settlement of the awards. The remaining 99,319 shares were withheld to satisfy income and payroll tax withholding obligations that occurred upon delivery of the shares underlying those RSUs.

Director Shares

During the second quarters of 2021, and 2020, the Company issued 57,795 and 267,576 shares, respectively, of its common stock to its non-employee directors under the Equity Plan. Shares issued during the second quarter of 2021 will fully vest on December 31, 2021. Shares issued during the second quarter of 2020 fully vested on December 31, 2020.

Employee Stock Purchase Plan

Under the Company’s Employee Stock Purchase Plan (“ESPP”), eligible employees may purchase shares of the Company’s common stock through payroll deductions of up to 15 percent of eligible compensation, ensuring that the accrual is no more than 2,500 shares per offering period and not in excess of $25,000 in value related to purchases for each calendar year. The purchase price of the stock is 85 percent of the lower of the fair market value of the stock on either the first or last day of the purchase period. The ESPP is intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code. There were 252,665 and 297,013 shares issued under the ESPP during the second quarters of 2021, and 2020, respectively. Total proceeds to the Company for the issuance of these shares was $1.3 million and $947,000 for the six months ended June 30, 2021, and 2020, respectively. The fair value of ESPP grants is measured at the date of grant using the Black-Scholes option-pricing model.
