If you retire with at least 10 years of eligible service, you are vested for medical insurance. The date the medical insurance takes effect will be based on if you: Meet the rule of 80. Retire from active employment.
If you're in Group 1, 2 or 3, your standard annuity amount is calculated by multiplying your years and months of service by 2.3% (2.8% for 20 years or more of certified law enforcement/custodial officer, or LECO, service), and multiplying the product of this by your highest average salary.
If you are actively employed with the state you can't withdraw or borrow from your retirement account. There are no partial withdrawals. If you are vested and separate from state employment, you can leave your account with ERS or process a withdrawal of your retirement contributions.
A 10% early withdrawal penalty may apply to withdrawals made prior to age 59½. The 10% federal early withdrawal penalty does not apply to the 457 plan withdrawals except for withdrawals attributable to rollovers from another type of plan or account.
