detail in the “—Potential Payments” section below, depending on the timing of such terminations, the performance-based phantom units will either vest at the time of termination, with the performance measures deemed met at the target level, or will remain outstanding and eligible to vest in accordance with their terms, as discussed below in the “—Potential Payments” section below.
In the event of a change in control, the performance measures associated with the performance-based phantom units will be scored based on the level of performance achieved during the period beginning on the first day of the performance period and ending on the latest practicable date prior to the change in control. If the performance-based phantom units, as scored, are not continued, assumed, substituted or replaced with an award that is either based (i) on shares of common stock or common units that are traded on a national securities exchange and are registered under the Securities Exchange Act of 1934, as amended, or (ii) on a U.S. dollar-denominated cash award, in each case, that has no less than equivalent economic value as immediately prior to the change in control, such performance-based phantom units will become vested in connection with the change in control. Any continued, assumed, substituted or replaced performance-based phantom units remain subject to accelerated vesting provisions described in the paragraph above.
Time-based Phantom Units
The time-based phantom units will vest one-third on each of the first three anniversaries following the date of grant.
The time-based phantom units are subject to accelerated vesting on the occurrence of any of the following events: (i) a termination of the NEO’s employment other than for cause, (ii) a termination of the NEO’s employment by the NEO for good reason or (iii) a termination of the NEO’s employment by reason of the NEO’s death or disability.
In the event of a change in control, the time-based phantom units will become vested only to the extent they are not continued, assumed, substituted or replaced as described above in the “Performance-based Phantom Units” section, and like the performance-based phantom units, if continued, assumed, substituted or replaced, the time-based phantom units will remain subject to the accelerated provisions described in the paragraph above.
Prior Year Awards
Due to the limited number of units available under the SMLP LTIP at the time of grant, awards granted under the SMLP LTIP in 2020, 2021 and 2022 were granted, in part, in the form of a cash retention bonus. The 2020 and 2021 awards vested and vest ratably over a three-year period, and the 2022 awards vested and vest 20%, 60% and 20% over a three-year period. To continue to align the interests of the Partnership’s senior management with our unitholders, following the approval of the new SMLP LTIP in 2022 (and the additional units available thereunder), in November 2022, the Compensation Committee approved a program pursuant to which each member of the Partnership’s senior management, including the NEOs, were given the opportunity to forfeit a portion of each outstanding vesting tranche of cash retention bonus awards previously granted in exchange for phantom units generally subject to the same terms and conditions (the “cash-to-phantom program”). A maximum of 300,000 phantom units were made available by the Compensation Committee under the cash-to-phantom program.
To the extent not forfeited pursuant to the cash-to-phantom program, (i) the final one-third of the 2020 awards, the second one-third of the 2021 awards and the first 20% of the 2022 awards vested in 2023, (ii) the remaining one-third of the 2021 awards and an additional 60% of the 2022 awards will vest in 2024, and (iii) the remaining 20% of the 2022 awards will vest in 2024.
Retirement, Health and Welfare and Additional Benefits
Our NEOs receive few perquisites or additional benefits. The NEOs are eligible to participate in such employee benefit plans and programs we offer to our employees, subject to the terms and eligibility requirements of those plans, and receive some additional benefits pursuant to the terms of their employment agreements.
401(k) Plan
The NEOs are eligible to participate in a tax qualified 401(k) defined contribution plan to the same extent as all of our other employees. In 2023, we made a fully vested matching contribution on behalf of each of the 401(k) plan’s participants up to 5% of such participant’s eligible salary for the year.
Health Savings Account Program
The NEOs are eligible to participate in a tax qualified health savings account (“HSA”) if they are enrolled in the available high-deductible health plan. The HSA is a tax-free savings account owned by an individual and can be used to pay for current or future qualified medical expenses. Participants determine how much to contribute, when and how to spend the money on eligible medical expenses, and how to invest the balance. The balance remains in the account and is not subject to forfeiture. The Partnership makes annual contributions to all HSA-eligible employees who enroll in and contribute to an HSA. In 2023, we made tax-free HSA contributions of $600 to each of Messrs. Deneke, Mault and Johnston.
