(b) The Board of Trustees shall fix and determine by appropriate rules and regulations how much service in any year is equivalent to one year of service, but in no case shall more than one year of service be creditable for all service in one calendar year.

(c) Subject to the above restrictions and to such other rules and regulations as the Board of Trustees may adopt, the Board of Trustees shall verify, as soon as practicable after the filing of such statements of service, the service therein claimed.

In lieu of a determination of the actual compensation of the members that was received during such period of prior service, the Board of Trustees may use for the purpose of this Article the compensation rates which if they had progressed with the rates of salary increase shown in the tables as prescribed in subsection (o) of G.S. §128-28 would have resulted in the same average salary of the member for the five years immediately preceding the date of participation of his employer, as the records show the member actually received.

(d) Any member may, up to his date of retirement and within one year thereafter, request the Board of Trustees to modify or correct his prior service credit.

(e) Creditable service at retirement on which the retirement allowance of a member shall be based shall consist of the membership service rendered by him since he last became a member, and also if he has a prior service certificate which is in full force and effect, the amount of the service certified on his prior service certificate; and if he has sick leave standing to his credit upon retirement on or after July 1, 1971, one month of credit for each 20 days or portion thereof, but not less than one hour; sick leave shall not be counted in computing creditable service for the purpose of determining eligibility for disability retirement or for a vested deferred allowance. Creditable service for unused sick leave shall be allowed only for sick leave accrued monthly during employment under a duly adopted sick leave policy and for which the member may be able to take credits and be paid for sick leave without restriction. However, in no instance shall unused sick leave be credited to a member's account at retirement if the member's last day of actual service is more than 365 days prior to the effective date of the member's retirement.

On and after July 1, 1971, a member whose account was closed on account of absence from service under the provisions of G.S. §128-24(1a) and who subsequently returns to service for a period of five years, may thereafter repay the amount withdrawn plus regular interest thereon from the date of withdrawal through the year of repayment and thereby increase his creditable service by the amount of creditable service lost when this account was closed.

On and after July 1, 1973, a member whose account in the Teachers' and State Employees' Retirement System was closed on account of absence from service under the provisions of G.S. §135-3(3) and who subsequently became or becomes a member of this System with credit for five years of service, may thereafter repay in a lump sum the amount withdrawn from the Teachers' and State Employees' Retirement System plus regular interest thereon from the date of withdrawal through the year of repayment and thereby increase his creditable service in this System by the amount of creditable service lost when his account was closed.

Notwithstanding any other provision of this Chapter, any member who entered service or was restored to service prior to July 1, 1982, and was excluded from membership service solely on account of having attained the age of 62 years, in accordance with former G.S. §128-24(3a), may purchase membership service credits for such excluded service by making a lump-sum payment equal to the contributions that would have been deducted pursuant to G.S. §128-30(b) had he been a member of the Retirement System, increased by interest calculated at a rate of seven percent (7%) per annum.

On and after January 1, 1986, the creditable service of a member who was a member of the Law Enforcement Officers' Retirement System at the time of the transfer of law enforcement officers employed by participating employers from that System to this Retirement System and whose accumulated contributions are transferred from that System to this Retirement System, includes service that was creditable in the Law Enforcement Officers' Retirement System; and membership service with that System is membership service with this Retirement System; provided, notwithstanding any provisions of this Article to the contrary, any inchoate or accrued rights of such a member to purchase creditable service for military service, withdrawn service and prior service under the rules and regulations of the Law Enforcement Officers' Retirement System may not be diminished and may be purchased as creditable service with this Retirement System under the same conditions that would have otherwise applied.

(f)   Effective January 1, 1955, there shall be three classes of prior service certificates, to be designated as Class A, Class B and Class C respectively. Each such certificate issued on account of service rendered to a Class A employer shall be a Class A prior service certificate; each such certificate issued on account of service rendered to a Class B employer shall be a Class B prior service certificate; and each such certificate issued on account of service rendered to a Class C employer shall be a Class C prior service certificate. Each Class C prior service certificate shall specify a prior service benefit percentage rate which shall be three per centum (3%) in the case of any member entitled to such certificate who is, at the date of participation of his employer, in a position covered by the Social Security Act under a federal-State agreement and which shall be five per centum (5%) in the case of a member entitled to such certificate but who at the date of participation of his employer is in a position not so covered.

(g) During periods when a member is on leave of absence and is receiving less than his full compensation, he will be deemed to be in service only if he is contributing to the Retirement System as provided in G.S. §128-30(b)(4). If he is so contributing, the annual rate of compensation paid to such employee immediately before the leave of absence began will be deemed to be the actual compensation rate of the employee during the leave of absence.

(h) Creditable service at retirement shall include any service rendered by a member while on leave of absence to serve as a member or officer of the General Assembly which is not creditable toward retirement under the Legislative Retirement Fund provided the allowance of such credit shall be contingent upon the cancellation of service credit in the fund and the transfer of the member's contributions plus accumulated interest from the fund to this System.

(h1) Any member may purchase creditable service for service as a member of the General Assembly not otherwise creditable under this section, provided the service is not credited in the Legislative Retirement Fund nor the Legislative Retirement System, and further provided the member pays a lump sum amount equal to the full cost of the additional service credits calculated on the basis of the assumptions used for the purposes of the actuarial valuation of the System's liabilities, taking into account the additional retirement allowance arising on account of the additional service credits commencing at the earliest age at which a member could retire on an unreduced retirement allowance as determined by the Board of Trustees upon the advice of the consulting actuary, plus an administrative fee to be set by the Board of Trustees. Notwithstanding the foregoing provisions of this subsection that provide for the purchase of service credits, the terms "full cost", "full liability", and "full actuarial cost" include assumed annual post-retirement allowance increases, as determined by the Board of Trustees, from the earliest age at which a member could retire on an unreduced service allowance.

(i)   Notwithstanding any other provision of this Chapter, any person who withdrew his contributions in accordance with the provisions of G.S. §128-27(f) or §135-5(f) or the rules and regulations of the Law Enforcement Officers' Retirement System and who subsequently returns to service may, upon completion of five years of prior and current membership service, repay in a total lump sum any and all of the accumulated contributions previously withdrawn with interest compounded annually at the rate of six and one-half percent (6.5%) for each calendar year from the year of withdrawal to the year of repayment plus a fee to cover expense of handling which shall be determined by the Board of Trustees, and receive credit for the service forfeited at time of withdrawal(s). These provisions shall apply equally to retired members who had attained five years of prior and current membership service prior to retirement. The retirement allowance of a retired member who restores service under this subsection shall be increased the month following the month payment is received. The increase in the retirement allowance shall be the difference between the initial retirement allowance, under any optional allowance elected at the time of retirement, and the amount of the retirement allowance, under any optional allowance elected at the time of retirement, to which the retired member would have been entitled had the service not been previously forfeited, adjusted by any increases in the retirement accrual rate occurring between the member's date of retirement and the date of payment. The increase in the retirement allowance shall not include any adjustment for cost-of-living increases granted since the date of retirement.

(j)   Repealed by Session Laws 1987, c. 617, s. 3.

(j1) Notwithstanding any other provision of this Chapter, any member and any retired member as herein described may purchase creditable service for service in the Armed Forces of the United States, not otherwise allowed, by paying a total lump sum payment determined as follows:

1. For members who completed 10 years of membership service, and retired members who completed 10 years of membership service prior to retirement, and whose membership began on or prior to January 1, 1988, and who make such purchase within three years after first becoming eligible, the cost shall be an amount equal to the monthly compensation the member earned when the member first entered membership service times the employee contribution rate at that time times the months of service to be purchased with sufficient interest added thereto so as to equal one‑half of the cost of allowing such service, plus an administrative fee to be set by the Board of Trustees.
    

2. For members who complete five years of membership service, and retired members who complete five years of membership service prior to retirement, and eligible members and retired members covered by paragraph (1) of this subdivision, whose membership began on or before January 1, 1988, but who did not or do not make such purchase within three years after first becoming eligible, the cost shall be an amount equal to the full liability of the service credits calculated on the basis of the assumptions used for the purposes of the actuarial valuation of the System's liabilities and shall take into account the retirement allowance arising on account of the additional service credits commencing at the earliest age at which the member could retire on an unreduced allowance, as determined by the Board of Trustees upon the advice of the consulting actuary, plus an administrative fee to be set by the Board of Trustees. Notwithstanding the foregoing provisions of this subsection that provide for the purchase of service credits, the term "full liability" includes assumed post-retirement allowance increases, as determined by the Board of Trustees, from the earliest age at which a member could retire on an unreduced service retirement allowance.

Creditable service allowed under this subdivision shall be only for the initial period of "active duty", as defined in 38 U.S. Code Section 101(21), in the Armed Forces of the United States up to the date the member was first eligible to be separated and released and for subsequent periods of "active duty", as defined in 38 U.S. Code Section 101(21), as required by the Armed Forces of the United States up to the date of first eligibility for separation or release, but shall not include periods of active duty in the Armed Forces of the United States creditable in any other retirement system except the national guard or any reserve component of the Armed Forces of the United States, and shall not include periods of "active duty for training", as defined in 38 U.S. Code Section 101(22), or periods of "inactive duty training", as defined in 38 U.S. Code Section 101(23), rendered in any reserve component of the Armed Forces of the United States. Provided, creditable service may be allowed only for active duty in the Armed Forces of the United States of a member that resulted in a general or honorable discharge from duty. The member shall submit satisfactory evidence of the service claimed. For purposes of this subsection, membership service may include any membership or prior service credits transferred to this Retirement System pursuant to G.S. §128-24.

(j2) Notwithstanding any other provision of this Chapter, any member and any retired member as herein described may purchase creditable service previously rendered to any state, territory, or other governmental subdivision of the United States other than this State by paying a total lump-sum payment determined as follows:

1. For members who completed 10 years of prior and current membership service, and retired members who completed 10 years of prior and current membership service prior to retirement, and whose membership began on or before January 1, 1988, and who make such purchase within three years after first becoming eligible, the cost shall be an amount equal to the monthly compensation the member earned when he first entered membership service, times the employee contribution rate at that time, times the months of service to be purchased, times two, with sufficient interest added thereto so as to equal the full cost of allowing such service, plus an administrative fee to be set by the Board of Trustees.
    

2. For members who complete five years of prior and current membership service, and retired members who complete five years of prior and current membership service prior to retirement, and eligible members and retired members covered by subdivision (1) of this subsection, whose membership began on or before January 1, 1988, but who did not or do not make such purchase within three years after first becoming eligible, the cost shall be an amount equal to the full liability of the service credits calculated on the basis of the assumptions used for the purposes of the actuarial valuation of the System's liabilities and shall take into account the retirement allowance arising on account of the additional service credits commencing at the earliest age at which the member could retire on an unreduced allowance, as determined by the Board of Trustees upon the advice of the consulting actuary, plus an administrative fee to be set by the Board of Trustees. Notwithstanding the foregoing provisions of this subsection that provide for the purchase of service credits, the term "full liability" includes assumed postretirement allowance increases, as determined by the Board of Trustees, from the earliest age at which a member could retire on an unreduced service retirement allowance. Notwithstanding the requirement of five years of current membership service, a member whose membership began prior to the service the member desires to purchase shall be eligible to purchase creditable service under this subdivision upon returning to service as an employee upon completion of a total of five years of membership service and upon completion of one year of current membership service.

Current membership service shall mean membership service earned since the service previously rendered to any state, territory, or other governmental subdivision of the United States other than this State. Creditable service under this subsection shall be allowed only at the rate of one year of out-of-state service for each year of service in this State, with a maximum allowable of 10 years of out-of-state service. Such service is limited to full-time service which would be allowable under the laws governing this System. Credit will be allowed only if no benefit is allowable in another public retirement system as a result of the service.

(k) Notwithstanding any language to the contrary of any provision of this section, or of any repealed provision of this section that was repealed with the inchoate and accrued rights preserved, all repayments and purchases of service credits, allowed under the provisions of this section or of any repealed provision of this section that was repealed with inchoate and accrued rights preserved, must be made within three years after the member first becomes eligible to make such repayments and purchases. Any member who does not repay or purchase service credits within said three years after first eligibility to make such repayments and purchases may, under the same conditions as are otherwise required, repay or purchase service credits provided that the repayment or purchase equals the full cost of the service credits calculated on the basis of the assumptions used for purchases of the actuarial valuation of the System's liabilities and shall take into account the additional retirement allowance arising on account of such additional service credit commencing at the earliest age at which such member could retire on an unreduced retirement allowance as determined by the Board of Trustees upon the advice of the consulting actuary. Notwithstanding the foregoing provisions of this subsection that provide for the purchase of service credits, the terms "full cost", "full liability", and "full actuarial cost" include assumed annual post-retirement allowance increases, as determined by the Board of Trustees, from the earliest age at which a member could retire on an unreduced service allowance. Notwithstanding the foregoing, on and after January 1, 2003, the provisions of this subsection shall not apply to the repayment of contributions withdrawn pursuant to subsection (i) of this section.

(l)   Notwithstanding any other provision of this Chapter, any member may purchase creditable service for periods of employer approved leaves of absence when in receipt of benefits under the North Carolina Workers' Compensation Act. This service shall be purchased by paying a cost calculated in the following manner:

1. Leaves of Absence Terminated Prior to July 1, 1983. – The cost to a member whose employer approved leave of absence, when in receipt of benefits under the North Carolina Workers' Compensation Act, terminated upon return to service prior to July 1, 1983, shall be a lump sum amount payable to the Annuity Savings Fund equal to the full liability of the service credits calculated on the basis of the assumptions used for purposes of the actuarial valuation of the system's liabilities, and shall take into account the retirement allowance arising on account of the additional service credit commencing at the earliest age at which the member could retire on an unreduced retirement allowance, as determined by the board of trustees upon the advice of the consulting actuary, plus an administrative fee to be set by the Board of Trustees. Notwithstanding the foregoing provisions of this subdivision that provide for the purchase of service credits, the terms "full cost", "full liability", and "full actuarial cost" include assumed annual post-retirement allowance increases, as determined by the Board of Trustees, from the earliest age at which a member could retire on an unreduced service allowance.
    

2. Leaves of Absence Terminating On and After July 1, 1983. – The cost to a member whose employer approved leave of absence, when in receipt of benefits under the North Carolina Workers' Compensation Act, terminates upon return to service on and after July 1, 1983, shall be a lump sum amount due and payable to the Annuity Savings Fund within six months from return to service equal to the total employee and employer percentage rates of contribution in effect at the time of purchase and based on the annual rate of compensation of the member immediately prior to the leave of absence; Provided, however, the cost to a member whose amount due is not paid within six months from return to service shall be the amount due plus one percent (1%) per month penalty for each month or fraction thereof the payment is made beyond the six-month period.

Whenever the creditable service purchased pursuant to this subsection is for a period that occurs during the four consecutive calendar years that would have produced the highest average annual compensation pursuant to G.S. §128-21(5) had the member not been on leave of absence without pay, then the compensation that the member would have received during the purchased period shall be included in calculating the member's average final compensation. In such cases, the compensation that the member would have received during the purchased period shall be based on the annual rate of compensation of the member immediately prior to the leave of absence.

In the case of a law enforcement officer electing to purchase service under this section who is in receipt of benefits under the North Carolina Workers' Compensation Act due to serious bodily injury suffered in the line of duty as a result of an intentional or unlawful act of another, as certified by the head of the employing law enforcement agency, and whose approved leave of absence terminates on or before a return to service on and after August 1, 2006, the employer percentage rate of contribution payable under subdivision (2) of this subsection shall be made by the employer that granted the leave of absence. The cost to the law enforcement officer shall be reduced by the amount paid by the employer. For purposes of this subsection, "serious bodily injury" means bodily injury that creates a substantial risk of death, or that causes serious permanent disfigurement, coma, a permanent or protracted condition that causes extreme pain, or permanent or protracted loss or impairment of the function of any bodily member or organ, or that results in prolonged hospitalization.

Nothing in this subsection prevents an employer from voluntarily paying all or a part of the employee portion of the total cost of the service credit purchased, and the employer does not discriminate against any eligible law enforcement officer in this subsection employed by the employer by paying that portion of cost. To the extent paid by the employer, the employee portion paid by the employer shall be credited to the Pension Accumulation Fund; to the extent paid by the member, the employee portion paid by the member shall be credited to the member's annuity savings account. A member shall pay any part of the employee portion of the total cost not paid by the employer."

Changes to G.S. §128-26(l) will become effective August 1, 2006, and apply to members who return to service from an approved leave of absence on or after that date.

(m) Omitted Membership Service. – A member who had service as an employee as defined in G.S. §135-1(10) and G.S. §128-21(10) or as a teacher as defined in G.S. §135-1(25) and who was omitted from contributing membership through error may be allowed membership service, after submitting clear and convincing evidence of the error, as follows:

1. within 90 days of the omission, by the payment of employee and employer contributions that would have been paid; or
    

2. after 90 days and prior to three years of the omission, by the payment of the employee and employer contributions that would have been paid plus interest compounded annually at a rate equal to the greater of the average yield on the pension accumulation fund for the preceding calendar year or the actuarial investment rate-of-return assumption, as adopted by the Board of Trustees; or
    

3. after three years of the omission, by the payment of an amount equal to the full cost of the service credits calculated on the basis of the assumptions used for the purposes of the actuarial valuation of the System's liabilities, and shall take into account the additional retirement allowance arising on account of such additional service credit commencing at the earliest age at which a member could retire on an unreduced retirement allowance, as determined by the Board of Trustees upon the advice of the consulting actuary, plus an administrative fee to be set by the Board of Trustees. Notwithstanding the foregoing provisions of this subdivision that provide for the purchase of service credits, the terms "full cost", "full liability", and "full actuarial cost" include assumed annual post-retirement allowance increases, as determined by the Board of Trustees, from the earliest age at which a member could retire on an unreduced service allowance.

Nothing contained in this subsection shall prevent an employer or member from paying all or a part of the cost of the omitted membership service; and to the extent paid by the employer, the cost paid by the employer shall be credited to the pension accumulation fund; and to the extent paid by the member, the cost paid by the members shall be credited to the member's annuity savings account; provided, however, an employer does not discriminate against any member or group of members in his employ in paying all or any part of the cost of the omitted membership service. In the event an employer pays all or a part of the full actuarial cost as determined in subdivision (3) of this subsection, the employer may, at its option, pay such amount either in a lump sum or by increasing its "accrued liability contribution" for the remainder of its accrued liability period. In the event an employer has satisfied its accrued liability contribution, the employer may amortize its portion of the full actuarial cost over a period not to exceed ten years. The expense of making an actuarial valuation to determine the accrued liability contribution or the additional accrued liability contribution, required to amortize the portion of the full actuarial cost paid by the employer, shall be paid by the employer in a lump sum at the time of the actuarial valuation.

(n) Repealed by Session Laws 2002-153, s. 3, effective January 1, 2003.

(o) Credit at Full Cost for Federal Employment. – Notwithstanding any other provisions of this Chapter, a member, upon the completion of five years of membership service, may purchase creditable service for periods of federal employment, provided that the member is not receiving any retirement benefits resulting from this federal employment, and provided that the member is not vested in the particular federal retirement system to which the member may have belonged while a federal employee. The member shall purchase this service by making a lump sum amount payable to the Annuity Savings Fund equal to the full liability of the service credits calculated on the basis of the assumptions used for purposes of the actuarial valuation of the liabilities of the Retirement System; and the calculation of the amount payable shall take into account the retirement allowance arising on account of the additional service credit commencing at the earliest age at which the member could retire on an unreduced retirement allowance, as determined by the Board of Trustees upon the advice of the consulting actuary, plus an administrative fee to be set by the Board of Trustees. Members may also purchase creditable service for periods of employment with public community service entities within the State funded entirely with federal funds, other than the federal government, that are not covered by the provisions of G.S. §128-21(11) or G.S. §135-1(11), under the same terms and conditions that are applicable to the purchase of creditable service for periods of federal employment in accordance with this subsection. "Public community service entities" as used in this subsection shall mean community action, human relations, manpower development, and community development programs as defined in Articles 19 and 21 of Chapter 160A and Article 18 of Chapter 153A of the General Statutes and any other similar programs that the Board of Trustees may adopt. Notwithstanding the foregoing provisions of this subsection that provide for the purchase of service credits, the terms "full cost", "full liability", and "full actuarial cost" include assumed annual post-retirement allowance increases, as determined by the Board of Trustees, from the earliest age at which a member could retire on an unreduced service allowance.

(p) Part-Time Service Credit. –

1. Notwithstanding any other provision of this Chapter, upon completion of five years of membership service, any member may purchase service previously rendered as a part-time employee of a participating employer as defined in G.S. §128-21(11) or G.S. §135-1(11), except for temporary or part-time service rendered while a full-time student in pursuit of a degree or diploma in a degree-granting program. Payment shall be made in a single lump sum in an amount equal to the full actuarial cost of providing credit for the service, together with interest and an administrative fee, as determined by the Board of Trustees on the advice of the Retirement System's actuary. Notwithstanding the provisions of G.S. §128-26(b), the Board of Trustees shall fix and determine by appropriate rules and regulations how much service in any year, as based on compensation, is equivalent to one year of service in proportion to "earnable compensation", but in no case shall more than one year of service be creditable for all service in one year. Notwithstanding the foregoing provisions of this subdivision that provide for the purchase of service credits, the terms "full cost", "full liability", and "full actuarial cost" include assumed annual post-retirement allowance increases, as determined by the Board of Trustees, from the earliest age at which a member could retire on an unreduced service allowance.
    

2. Under all requirements and conditions set forth in the preceding subdivision of this subsection, except for the requirement that the completion of five years of membership service be subsequent to service rendered as a part-time employee, any member with five or more years of membership service standing to his credit may purchase additional membership service for service rendered as a part-time employee of an employer as defined in G.S. §128-21(11) if (i) the member terminates or has terminated employment in any capacity as an employee, (ii) the purchase of the additional membership service causes the member to become eligible to commence an early or service retirement allowance, and (iii) the member immediately elects to commence retirement and become a beneficiary.

(q) Credit at Full Cost for Probationary Employment. – Notwithstanding any other provision of this Chapter, a member may purchase creditable service, prior to retirement, for employment with an employer as defined in this Article when considered to be in a probationary or employer imposed waiting period status and thereby not regularly employed, between date of employment and date of membership service with the retirement system, provided that the employer or former employer of such a member has revoked this probationary employment or waiting period policy.

Provided, the member shall purchase this service by making a lump sum amount payable to the Annuity Savings Fund equal to the full liability of the service credits calculated on the basis of the assumptions used for purposes of the actuarial valuation of the liabilities of the retirement system, and the calculation of the amount payable shall take into account the retirement allowance arising on account of the additional service credit commencing at the earliest age at which the member could retire on an unreduced retirement allowance, as determined by the Board of Trustees upon the advice of the consulting actuary, plus an administrative fee to be set by the Board of Trustees. In no instance shall the amount payable be less than the contributions a member would have made during the employment plus four percent (4%) interest compounded annually.

Notwithstanding the foregoing provisions of this subsection that provide for the purchase of service credits, the terms "full cost", "full liability", and "full actuarial cost" include assumed annual post-retirement allowance increases, as determined by the Board of Trustees, from the earliest age at which a member could retire on an unreduced service allowance.

Nothing contained in this subsection shall prevent an employer or member from paying all or a part of the cost of the probationary employment; and to the extent paid by the employer, the cost paid by the employer shall be credited to the pension accumulation fund; and to the extent paid by the member, the cost paid by the member shall be credited to the member's annuity savings account; provided, however, an employer does not discriminate against any member or group of members in its current employ in paying all or any part of the cost of the probationary employment. In the event an employer pays all or a part of the full actuarial cost, the employer may, at its option, pay such amount either in a lump sum or by increasing its "accrued liability contribution" for the remainder of its accrued liability period. In the event an employer has satisfied its accrued liability contribution, the employer may amortize its portion of the full actuarial cost over a period not to exceed 10 years. The expense of making an actuarial valuation to determine the accrued liability contribution or the additional accrued liability contribution, required to amortize the portion of the full actuarial cost paid by the employer, shall be paid by the employer in a lump sum at the time of the actuarial valuation.

(r)   Credit at Full Cost for Temporary Government Employment. – Notwithstanding any other provisions of this Chapter, any member may purchase creditable service for government employment when classified as a temporary employee subject to the conditions that:

1. The member was employed by an employer as defined in G.S. §128-21(11) or G.S. §135-1(11);
    

2. The member's temporary employment met all other requirements of G.S. §128-21(10), or G.S. §135-1(10) or (25);

4. The member acquires from the employer such certifications of temporary employment as are required by the Board of Trustees; and
    

5. The member makes a lump sum payment into the Annuity Savings Fund equal to the full liability of the service credits calculated on the basis of the assumptions used for purposes of the actuarial valuation of the retirement system's liabilities, and the calculation of the amount payable shall take into account the retirement allowance arising on account of the additional service credit commencing at the earliest age at which the member could retire on an unreduced retirement allowance, as determined by the Board of Trustees upon the advice of the actuary, plus an administrative fee to be determined by the Board of Trustees. Notwithstanding the foregoing provisions of this subdivision that provide for the purchase of service credits, the terms "full cost", "full liability", and "full actuarial cost" include assumed annual post-retirement allowance increases, as determined by the Board of Trustees, from the earliest age at which a member could retire on an unreduced service allowance.

(s) Credit at Full Cost for Employment Not Otherwise Creditable. – Notwithstanding any other provisions of this Chapter, any member may purchase creditable service for any employment as an employee, as defined in G.S. §128-21(10), of a local government employer not creditable in any other retirement system or plan, upon completion of five years of membership service by making a lump sum payment into the Annuity Savings Fund. The payment by the member shall be equal to the full liability of the service credits calculated on the basis of the assumptions used for purposes of the actuarial valuation of the retirement system's liabilities, and the calculation of the amount payable shall take into account the additional retirement allowance arising on account of the additional service credits commencing at the earliest age at which the member could retire with an unreduced retirement allowance, as determined by the Board of Trustees upon the advice of the actuary plus an administrative fee to be determined by the Board of Trustees. Notwithstanding the foregoing provisions of this subsection that provide for the purchase of service credits, the terms "full cost", "full liability", and "full actuarial cost" include assumed annual post-retirement allowance increases, as determined by the Board of Trustees, from the earliest age at which a member could retire on an unreduced service allowance.

(t)   Purchase of Service Credits Through Rollover Contributions From Certain Other Plans. – Notwithstanding any other provision of this Article, and without regard to any limitations on contributions otherwise set forth in this Article, a member, who is eligible to restore or purchase membership or creditable service pursuant to the provisions of G.S. §128-26, may, subject to such rules and regulations established by the Board of Trustees, purchase such service credits through rollover contributions to the Annuity Savings Fund from (i) an annuity contract described in Section 403(b) of the Internal Revenue Code, (ii) an eligible plan under Section 457(b) of the Internal Revenue Code which is maintained by a state, political subdivision of a state, or any agency or instrumentality of a state or political subdivision of a state, (iii) an individual retirement account or annuity described in Section 408(a) or 408(b) of the Internal Revenue Code that is eligible to be rolled over and would otherwise be includible in gross income, or (iv) a qualified plan described in Section 401(a) or 403(a) of the Internal Revenue Code. Notwithstanding the foregoing, the Retirement System shall not accept any amount as a rollover contribution unless such amount is eligible to be rolled over to a qualified trust in accordance with applicable law and the member provides evidence satisfactory to the Retirement System that such amount qualifies for rollover treatment. Unless received by the Retirement System in the form of a direct rollover, the rollover contribution must be paid to the Retirement System on or before the 60th day after the date it was received by the member.

Purchase of Service Credits Through Plan-to-Plan Transfers. – Notwithstanding any other provision of this Article, and without regard to any limitations on contributions otherwise set forth in this Article, a member, who is eligible to restore or purchase membership or creditable service pursuant to the provisions of G.S. §128-26, may, subject to such rules and regulations established by the Board of Trustees, purchase such service credits through a direct transfer to the Annuity Savings Fund of funds from (i) an annuity contract described in Section 403(b) of the Internal Revenue Code or (ii) an eligible plan under Section 457(b) of the Code which is maintained by a state, political subdivision of a state, or any agency or instrumentality of a state or political subdivision of a state.

(u) (See note.) Purchase of Service Credits Through Plan-to-Plan Transfers. – Notwithstanding any other provision of this Article, and without regard to any limitations on contributions otherwise set forth in this Article, a member, who is eligible to restore or purchase membership or creditable service pursuant to the provisions of G.S. §128-26, may, subject to such rules and regulations established by the Board of Trustees, purchase such service credits through a direct transfer to the Annuity Savings Fund of funds from (i) the Supplemental Retirement Income Plans A, B, or C of North Carolina or (ii) any other defined contribution plan qualified under Section 401(a) of the Internal Revenue Code which is maintained by the State of North Carolina, a political subdivision of a state, or any agency or instrumentality of a state or political subdivision of a state.

(u1) Credit at Full Cost for Nonqualified Employment. – Notwithstanding any other provisions of this Chapter, any member may purchase a maximum of five years of creditable service for nonqualified employment with an economic development organization that receives at least fifty percent (50%) of its funding from local government, upon the completion of five years of membership service, by making a lump-sum payment into the Annuity Savings Fund. The member shall obtain written verification of the service from the nonprofit corporation. The payment by the member shall be equal to the full liability of the service credits calculated on the basis of the assumptions used for purposes of the actuarial valuation of the Retirement System's liabilities, and the calculation of the amount payable shall take into account the additional retirement allowance arising on account of the additional service credits commencing at the earliest age at which the member could retire with an unreduced retirement allowance, as determined by the Board of Trustees upon the advice of the actuary, plus an administrative fee to be determined by the Board of Trustees. Notwithstanding the foregoing provisions of this subsection that provide for the purchase of service credits, the terms "full cost," "full liability," and "full actuarial cost" include assumed annual postretirement allowance increases, as determined by the Board of Trustees, from the earliest age at which a member could retire on an unreduced service allowance. [Note: Section (u1) became effective July 1, 2009, and applied to nonqualified employment with an economic development organization performed on or before December 31, 2009. Section (u1) expired December 31, 2009, provided that any inchoate rights that may accrue to a member under this act shall not be diminished. ]

(v) A member who is reinstated to service as an employee as defined in G.S. 128-21(10) retroactively to the date of prior involuntary termination with back pay and associated benefits may be allowed membership service, after submitting clear and convincing evidence of the reinstatement, payment of back pay, and restoration of associated benefits, as follows:

1. When the reinstatement to service is by court order and is:
    
1. Within 90 days of the involuntary termination, by the payment of employee and employer contributions that would have been paid; or
    
2. After 90 days of the involuntary termination, by the payment of the employee and employer contributions that would have been paid plus interest compounded annually at a rate equal to the greater of the average yield on the pension accumulation fund for the preceding calendar year or the actuarial investment rate-of-return assumption, as adopted by the Board of Trustees.
    
2. When the reinstatement to service is by settlement agreement voluntarily entered into by the affected parties, by the payment of a lump-sum amount equal to the full liability of the service credits calculated on the basis of the assumptions used for purposes of the actuarial valuation of the system's liabilities, taking into account the retirement allowance arising on account of the additional service credit commencing at the earliest age at which the member could retire on an unreduced retirement allowance, as determined by the Board of Trustees upon the advice of the consulting actuary, plus an administrative fee to be set by the Board of Trustees. Notwithstanding the foregoing provisions of this subsection that provide for the purchase of service credits, the terms "full cost," "full liability," and "full actuarial cost" include assumed annual postretirement allowance increases, as determined by the Board of Trustees, from the earliest age at which a member could retire on an unreduced service allowance.

Nothing contained in this subsection shall prevent an employer or member from paying all or a part of the cost of the retroactive membership service; and to the extent paid by the employer, the cost paid by the employer shall be credited to the pension accumulation fund; and to the extent paid by the member, the cost paid by the member shall be credited to the member's annuity savings account; provided, however, an employer does not discriminate against any member or group of members in his employ in paying all or any part of the cost of the retroactive membership service.

In the event a member received a return of accumulated contributions subsequent to an involuntary termination as provided in G.S. §128-27(f), the member may redeposit, within 90 days of reinstatement retroactive to the date of prior involuntary termination, in the annuity savings fund by single payment, an amount equal to the total amount he previously withdrew plus regular interest and restore the creditable service forfeited upon receiving his return of accumulated contributions.

(w) If a member who is an elected government official and has not vested in this System on July 1, 2007, is convicted of an offense listed in G.S. §128-38.4 for acts committed after July 1, 2007, then that member shall forfeit all benefits under this System, except for a return of member contributions plus interest. If a member who is an elected government official and has vested in this System on July 1, 2007, is convicted of an offense listed in G.S. §128-38.4 for acts committed after July 1, 2007, then that member is not entitled to any creditable service that accrued after July 1, 2007. No member shall forfeit any benefit or creditable service earned from a position not as an elected government official.

(x) If a member who is in service and has not vested in this System on December 1, 2012, is convicted of an offense listed in G.S. 128-38.4A for acts committed after December 1, 2012, then that member shall forfeit all benefits under this System, except for a return of member contributions plus interest. If a member who is in service and has vested in this System on December 1, 2012, is convicted of an offense listed in G.S. 128-38.4A for acts committed after December 1, 2012, then that member is not entitled to any creditable service that accrued after December 1, 2012.

(y) Contribution-Based Benefit Cap Purchase Provision. – If a member's retirement allowance is subject to an adjustment pursuant to the contribution-based benefit cap established in G.S. 128-27(a3), the retirement system shall notify the member and the member's employer that the member's retirement allowance has been capped. The retirement system shall compute and notify the member and the member's employer of the total additional amount the member would need to contribute in order to make the member not subject to the contribution-based benefit cap. This total additional amount shall be the actuarial equivalent of a single life annuity adjusted for the age of the member at the time of retirement, or when appropriate, the age at the time of the member's death that would have had to have been purchased to increase the member's benefit to the pre-cap level. The member shall have until 90 days after notification regarding this additional amount or until 90 days after the effective date of retirement, whichever is later, to submit a lump sum payment to the annuity savings fund in order for the retirement system to restore the retirement allowance to the uncapped amount. Nothing contained in this subsection shall prevent an employer from paying all or part of the cost of the amount necessary to restore the member's retirement allowance to the pre-cap amount.
