Stock-Based Awards

Note 4. Stock-Based Awards

Restricted Stock Units

We grant restricted stock units, or RSUs, with a service condition, and RSUs with market and service conditions, or MSUs. Historically we granted RSUs with performance and service conditions, or PSUs, as part of our annual bonus plan to our senior executives and other bonus-eligible employees, however, in fiscal year 2023, our bonus plan is solely cash-based

The following table summarizes activity for RSUs, PSUs and MSUs for the three months ended March 31, 2023 (in thousands):
