(5) If the additional contribution that is required or elected under paragraph (2) of this subsection (d) is not paid in full within the required time, the creditable service shall not be granted and the police officer (or the officer's surviving spouse or estate) shall be entitled to receive a refund of (i) any partial payment of the additional contribution that has been made by the police officer and (ii) those portions of the amounts transferred under subdivision (a)(1) of Section 3-110.7 or subdivisions (a)(1) and (a)(3) of Section 7-139.9 that represent employee contributions paid by the police officer (but not the accumulated interest on those contributions) and interest paid by the police officer to the prior pension fund in order to reinstate service terminated by acceptance of a refund. At the time of paying a refund under this item (5), the pension fund shall also repay to the pension fund from which the contributions were transferred under Section 3-110.7 or 7-139.9 the amount originally transferred under subdivision (a)(2) of that Section, plus interest at the rate of 6% per year, compounded annually, from the date of the original transfer to the date of repayment. Amounts repaid to the Article 7 fund under this provision shall be credited to the appropriate municipality.
Transferred credit that is not granted due to failure to pay the additional contribution within the required time is lost; it may not be transferred to another pension fund and may not be reinstated in the pension fund from which it was transferred.
