Ah, I did, and he slightly more than tripled my RSUs (from 150 to 500), but left my base the same. Which is also weird since that base is lower than my current one.
That's about $50K/yr, assuming a 4-year vest and today's price range. Nice job.
I assume they give out RSU more than cash because it's a better-aligned incentive (both in motivations and risk profile), and it makes your x% raise cheaper next year.
