Options. I am one month away from completing 4 years and vesting completes then too. I did not get any refresher on equity.
As far as I know, there was a round of raises/appraisals and end of year 3 but I was left out. I was on a F1 (student) visa when I started with this company and I was unlucky enough that I didn't get H1B visa until my 3rd attempt (lost the first 2 attempts in the lottery), I am guessing here, but I think I didn't get any raise/equity because they knew I couldn't afford to leave back then with my H1B processing still going on.
