If the total amount of payments under this paragraph is less than the total purchase payment amount under section 356.551, and the employee fails to make timely payments as determined by the Teachers Retirement Association, all payment amounts must be refunded to the applicable source.
An employee on a leave of absence from a classified position who is appointed to an acting, interim, or temporary unclassified position retains the retirement coverage that the employee had in the prior classified position for up to one year of covered employment. If the employee continues in the unclassified position, the employee has the option to make an election under subdivision 4, provided no previous election had been made under that subdivision.
Notwithstanding subdivision 1, an employee in a part-time eligible unclassified administrative position or eligible unclassified faculty position that constitutes less than 25 percent of a full academic year is eligible for Teachers Retirement Association coverage for all covered employment if the person certifies to the employer existing membership in the Teachers Retirement Association.
