Term Definition
Marginal Tax Rate The tax rate that applies to the next dollar of income generated.
Medicare -Assignment A health care provider who accepts Medicare assignment agrees to the Medicare approved amount as 80% payment for Part B services. A provider who does not accept Medicare assignment can legally charge the patient up to 15% above the Medicare approved amount.
Medicare -HMO Plan A Medicare HMO plan is a health plan offered by an HMO that has contracted with the federal government to provide health care services to individuals with Medicare Part A and Part B coverage. Plan participants agree to receive all services from plan providers — and Medicare, in turn, pays the HMO a monthly fee for each enrolled member.
Medicare - Part A Medicare Part A is hospital insurance that covers inpatient care in a hospital or skilled nursing facility, and also hospice care. Part A insurance is automatic and free for eligible retirees who are fully insured under Social Security and have applied for Social Security benefits, or who have paid sufficient Medicare payroll tax. Members who are not fully insured pay premiums that are based on the number of Social Security credits they've earned.
Medicare - Part B Medicare Part B is medical insurance that covers physician services, outpatient hospital care, lab and x-rays, ambulance charges, and some other services not covered by Medicare Part A. Part B coverage is voluntary and retirees do not have to be fully insured under Social Security to be eligible.   Members 65 or older who are not eligible for Part A coverage may elect to pay a flat rate for Part B coverage.
Medicare - Supplement Plan

A Medicare supplement plan is an indemnity plan for individuals who are enrolled in both Part A and Part B of Medicare. The plan supplements Medicare coverage by:

  • Paying Medicare Part A deductibles and copayments, as well as Medicare Part B deductibles and 20% of Medicare-approved amounts
  • Providing coverage for certain items that Medicare does not cover, such as some prescription drugs and care while traveling outside the United States
Member Contributions Member contributions are the retirement contributions made by members who participate in a contributory plan. The contribution amount is calculated by multiplying a percentage rate by the member's compensation earnable.
Member -Deferred

A deferred member is a contributory member who is vested (with 5 or more years of retirement plan/reciprocal retirement service credit) and who leaves his contributions on deposit with the retirement plan after either:

  • Terminating employment with the sponsor or
  • Transferring to a nonqualifying position and filing a written election with the Board of Retirement within 180 days from date of transfer   A deferred member is eligible to receive a retirement benefit from the retirement plan when he meets the minimum age and service requirements.
Member -Deferred Reciprocal A deferred reciprocal member is a contributory member who elected to defer his retirement and entered employment covered by a reciprocal retirement system within 6 months of termination from County or outside district service — regardless of the length of service prior to termination. This election is called a reciprocal deferral.
Member-Dual Status Dual status is given to a member who has been both a general member and a safety member (Plan A or B) and, therefore, has service credit in both a general and a safety plan. This occurs when a member changes job classifications and becomes eligible for the other type of membership — or when a safety member transfers to a nonqualifying position that allows him to retain membership only as a general member. Persons with dual membership status qualify at retirement to receive a combined retirement allowance based on the service credit earned during each type of membership.
Member -General A general member is a permanent employee of the plan sponsor working full time or more in a recognized position other than firefighting, or law enforcement.
Member-Retired A retired member is a former employee who has taken either a service retirement or a disability retirement.
Member-Safety A safety member is a permanent employee working full time or more in firefighting, or law enforcement.
Member-Vested A vested member is a member with at least 5 years of retirement service credit. A member may use reciprocal retirement system credit to meet vesting requirements.  
Membership Date The membership date for new members is generally the first day of the first pay period following the employee's hire date.

Minimum Distribution

§401 (a)(9) of the IRC provides that in order to be a qualified plan, the entire interest of each employee must

(1) be distributed no later than April 1 of the calendar year following the calendar year in which the employee attains 70 1/2 (for governmental plans, the later of the date previously stated), April 1 of the calendar year following the calendar year in which the employee retires, or

(2) begin to be distributed by the previous stated dates over the life of the employee, or lives of the employee and a designated beneficiary.

Minimum Participation Generally speaking, a qualified plan that bases eligibility for participation on age and service can not deny or delay participation beyond the time an employee reaches age 25 and completes one year of credited service with the sponsoring employer. If the plan provides for full and immediate vesting of all accrued benefits, however, participation may be denied until the employee reaches age 25 and completes three years of credited service. These rules apply to corporate (single employer) plans.
