401k end for vesting go by termination date or date of account closure by employer.

i was laid off after 1.79 years of employment with a company. the vesting schedule for this account has only one step, at two years it is vested 100% before that mark it is 0%. my former employer has not sent any paper work through to the company that is managing this account and unless it comes in the next few days the account will have been open for the two years. my question is what does the vesting schedule go by; actual dates of employment, or does it extend to the date that the employer sends the paperwork to the holdings company to release the account due to termination of employment. also if it matters the account value is over the $5000 mark but only with the monnies from the employer included.
