Insights

Equity Compensation Analyst

Large performance-based RSU grant to the CEO; neutral impact.

The filing lists an award of 37,500,000 RSUs to the CEO, each convertible into one share upon vesting. The grant is under the company’s 2015 Incentive Plan and uses performance milestones linked to share price and available cash, aligning equity delivery with specified outcomes.

Because vesting depends on achieving these metrics, actual share delivery is contingent. Beneficial ownership of 37,500,000 derivative securities is shown as direct, with a stated RSU price of $0. The practical impact will depend on milestone attainment and subsequent settlement terms disclosed in future materials.
