(h)  The actuarial data provided under Subsection (a)(4) of this section may not include the identifying information of individual members.
Sec. 8C.  INITIAL RISK SHARING VALUATION STUDIES; CORRIDOR MIDPOINT AND CITY CONTRIBUTION AMOUNTS.  (a)  The pension system and the city shall separately cause their respective actuaries to prepare an initial risk sharing valuation study that is dated as of July 1, 2016, in accordance with this section.  An initial risk sharing valuation study must:
(1)  except as otherwise provided by this section, be prepared in accordance with Section 8B of this Act, and for purposes of Section 8B(a)(4) of this Act, be based on actuarial data as of June 30, 2016, or, if actuarial data is not provided, on estimates of actuarial data;

(3)  subject to Subsections (i) and (j) of this section, include a schedule of city contribution amounts for 30 fiscal years beginning with the fiscal year beginning July 1, 2017.
(b)  If the initial risk sharing valuation study has not been prepared consistent with this section before the year 2017 effective date, as soon as practicable after the year 2017 effective date:
(1)  the pension system shall provide to the city actuary under a confidentiality agreement the necessary actuarial data used by the pension system actuary to prepare the proposed initial risk sharing valuation study; and
(2)  not later than the 30th day after the date the city's actuary receives the actuarial data:
(A)  the city actuary, at the direction of the city, shall provide a proposed initial risk sharing valuation study to the pension system actuary; and
(B)  the pension system actuary, at the direction of the pension system, shall provide a proposed initial risk sharing valuation study to the city actuary.
(c)  If, after exchanging proposed initial risk sharing valuation studies under Subsection (b)(2) of this section, it is determined that the difference between the estimated total city contribution divided by the pensionable payroll for any fiscal year in the proposed initial risk sharing valuation study prepared by the pension system actuary and in the proposed initial risk sharing valuation study prepared by the city actuary is:
(1)  less than or equal to two percentage points, the estimated city contribution rate and the estimated city contribution amount for that fiscal year recommended by the pension system actuary will be the estimated city contribution rate and the estimated city contribution amount, as applicable, for purposes of Section 8B(a)(5) of this Act; or
(2)  greater than two percentage points, the city actuary and the pension system actuary shall have 20 business days to reconcile the difference and:
(A)  if, as a result of reconciliation efforts under this subdivision, the difference in any fiscal year is reduced to less than or equal to two percentage points, the city contribution rate and the city contribution amount recommended by the pension system actuary for that fiscal year will be the estimated city contribution rate and the estimated city contribution amount, as applicable, for purposes of Section 8B(a)(5) of this Act; or
(B)  if, after 20 business days, the city actuary and the pension system actuary are not able to reach a reconciliation that reduces the difference to an amount less than or equal to two percentage points for any fiscal year:
(i)  the city actuary at the direction of the city and the pension system actuary at the direction of the pension system each shall deliver to the finance director of the city and the executive director of the pension system a final initial risk sharing valuation study with any agreed-to changes, marked as the final initial risk sharing valuation study for each actuary; and
(ii)  the finance director and the executive director shall execute a joint addendum to the final initial risk sharing valuation study that is a part of each final initial risk sharing valuation study for all purposes and that reflects the arithmetic average of the estimated city contribution rate and the estimated city contribution amount for each fiscal year in which the difference was greater than two percentage points for purposes of Section 8B(a)(5) of this Act, and for reporting purposes the pension system may treat the pension system actuary's initial risk sharing valuation study with the addendum as the final initial risk sharing valuation study.
(d)  In preparing the initial risk sharing valuation study, the city actuary and pension system actuary shall:
(1)  adjust the actuarial value of assets to be equal to the market value of assets as of July 1, 2016;
(2)  assume the issuance of planned pension obligation bonds by December 31, 2017, in accordance with Subsection (j)(2) of this section; and
(3)  assume benefit and contribution changes under this Act as of the year 2017 effective date.
(e)  If the city actuary does not prepare an initial risk sharing valuation study for purposes of this section, the pension system actuary's initial risk sharing valuation study will be used as the final risk sharing valuation study for purposes of this Act unless the city did not prepare a proposed initial risk sharing valuation study because the pension system actuary did not provide the necessary actuarial data in a timely manner.  If the city did not prepare a proposed initial risk sharing valuation study because the pension system actuary did not provide the necessary actuarial data in a timely manner, the city actuary shall have 60 days to prepare the proposed initial risk sharing valuation study on receipt of the necessary information.
(f)  If the pension system actuary does not prepare a proposed initial risk sharing valuation study for purposes of this section, the proposed initial risk sharing valuation study prepared by the city actuary will be the final risk sharing valuation study for purposes of this Act.

(1)  if at any time the funded ratio is equal to or greater than 100 percent; or
(2)  for any fiscal year after the payoff year of the legacy liability.
(h)  If the city and the pension board have not entered into an agreement described by Subsection (g) of this section in a given fiscal year, the corridor midpoint will be the corridor midpoint determined for the 31st fiscal year in the initial risk sharing valuation study prepared in accordance with this section.
(i)  If the city makes a contribution to the pension system of at least $5 million more than the amount that would be required by Section 8A(a) of this Act, a liability gain layer with the same remaining amortization period as the legacy liability is created.  In each subsequent risk sharing valuation study until the end of that amortization period, the city contribution amount must be decreased by the amortized amount in each fiscal year covered by the liability gain layer.
(j)  Notwithstanding any other provision of this Act, including Section 8H of this Act:
(1)  if the city fails to deliver the proceeds of pension obligation bonds totaling $250 million on or before March 31, 2018, the pension board shall have 30 days from March 31, 2018, to rescind, prospectively, any or all benefit changes made effective under S.B. No. 2190, Acts of the 85th Legislature, Regular Session, 2017, as of the year 2017 effective date, or to reestablish the deadline for the delivery of pension obligation bond proceeds, reserving the right to rescind the benefit changes authorized by this subdivision if the bond proceeds are not delivered by the reestablished deadline; and
(2)  subject to Subsection (k) of this section, if the pension board rescinds benefit changes under Subdivision (1) of this subsection or pension obligation bond proceeds are not delivered on or before December 31, 2017, the initial risk sharing valuation study shall be prepared again and restated without assuming the delivery of the pension obligation bond proceeds, the later delivery of pension obligation bond proceeds, or the rescinded benefit changes, as applicable, including a reamortization of the city contribution amount for the amortization period remaining for the legacy liability, and the resulting city contribution rate and city contribution amount will become effective in the fiscal year following the completion of the restated initial risk sharing valuation study.
(k)  The restated initial risk sharing valuation study required under Subsection (j)(2) of this section must be completed at least 30 days before the start of the fiscal year:
(1)  ending June 30, 2019, if the pension board does not reestablish the deadline under Subsection (j)(1) of this section; or
(2)  immediately following the reestablished deadline, if the pension board reestablishes the deadline under Subsection (j)(1) of this section and the city fails to deliver the pension obligation bond proceeds described by Subsection (j)(1) of this section by the reestablished deadline.
Sec. 8D.  ACTUARIAL EXPERIENCE STUDIES.  (a)  At least once every four years, the pension system actuary, at the direction of the pension system, shall conduct an actuarial experience study in accordance with actuarial standards of practice.  The actuarial experience study required by this subsection must be completed not later than September 30 of the year in which the study is required to be conducted.
(b)  Except as otherwise expressly provided by Sections 8B(a)(7)(A)-(I) of this Act, actuarial assumptions and methods used in the preparation of a risk sharing valuation study, other than the initial risk sharing valuation study, shall be based on the results of the most recent actuarial experience study.

During the period prescribed by this subsection, the independent actuary may discuss recommendations in simultaneous consultation with the pension system actuary and the city actuary.
(l)  The pension system and the city may not seek any information from any prospective independent actuary about possible outcomes of the independent actuary's review.
(m)  If an independent actuary has questions or concerns regarding an engagement entered into under this section, the independent actuary shall simultaneously consult with both the city actuary and the pension system actuary regarding the questions or concerns.  This subsection does not limit the pension system's authorization to take appropriate steps to complete the engagement of the independent actuary on terms acceptable to both the pension system and the city or to enter into a confidentiality agreement with the independent actuary, if needed.
(n)  If the pension board does not adopt an assumption or method recommended by the city actuary to which the independent actuary agrees, or recommended by the pension system actuary, the city actuary is authorized to use that recommended assumption or method in connection with preparation of a subsequent risk sharing valuation study under Section 8B of this Act until the risk sharing valuation study following the next actuarial experience study is prepared.
Sec. 8E.  CITY CONTRIBUTION RATE WHEN ESTIMATED CITY CONTRIBUTION RATE LOWER THAN CORRIDOR MIDPOINT; AUTHORIZATION FOR CERTAIN ADJUSTMENTS.  (a)  This section governs the determination of the city contribution rate applicable in a fiscal year if the estimated city contribution rate is lower than the corridor midpoint.

(1)  less than 90 percent, the city contribution rate for the fiscal year equals the corridor midpoint; or
(2)  equal to or greater than 90 percent and the city contribution rate is:
(A)  equal to or greater than the minimum contribution rate, the estimated city contribution rate is the city contribution rate for the fiscal year; or
(B)  except as provided by Subsection (e) of this section, less than the minimum contribution rate for the corresponding fiscal year, the city contribution rate for the fiscal year equals the minimum contribution rate achieved in accordance with Subsection (c) of this section.
(c)  For purposes of Subsection (b)(2)(B) of this section, the following adjustments shall be applied sequentially to the extent required to increase the estimated city contribution rate to equal the minimum contribution rate:
(1)  first, adjust the actuarial value of assets equal to the current market value of assets, if making the adjustment causes the city contribution rate to increase; 
(2)  second, under a written agreement between the city and the pension board under Section 3(n) of this Act entered into not later than the 30th day before the first day of the next fiscal year, prospectively restore all or part of any benefit reductions or reduce increased employee contributions, in each case made after the year 2017 effective date;
(3)  third, accelerate the payoff year of the legacy liability by offsetting the remaining legacy liability by the amount of the new liability loss layer, provided that during the accelerated period the city will continue to pay the city contribution amount as scheduled in the initial risk sharing valuation study, subject to Section 8C(i) or (j) of this Act;
(4)  fourth, accelerate the payoff year of existing liability loss layers, excluding the legacy liability, by accelerating the oldest liability loss layers first, to an amortization period of not less than 20 years from the first day of the fiscal year beginning 12 months after the date of the risk sharing valuation study in which the liability loss layer is first recognized; and
(5)  fifth, under a written agreement between the city and the pension board under Section 3(n) of this Act entered into not later than the 30th day before the first day of the next fiscal year, the city and the pension board may agree to reduce the assumed rate of return.

(2)  greater than 100 percent in a written agreement between the city and the pension system entered into under Section 3(n) of this Act, the pension system may reduce member contributions or increase pension benefits if as a result of the action:
(A)  the funded ratio is not less than 100 percent; and
(B)  the city contribution rate is not more than the minimum contribution rate.
(e)  Except as provided by Subsection (f) of this section, if an agreement under Subsection (d) of this section is not reached on or before the 30th day before the first day of the next fiscal year, before the first day of the next fiscal year, the pension board shall reduce member contributions and implement or increase cost-of-living adjustments, but only to the extent that the city contribution rate is set at or below the minimum contribution rate and the funded ratio is not less than 100 percent.
(f)  If any member contribution reduction or benefit increase under Subsection (e) of this section has occurred within the previous three fiscal years, the pension board may not make additional adjustments to benefits, and the city contribution rate must be set to equal the minimum contribution rate.
Sec. 8F.  CITY CONTRIBUTION RATE WHEN ESTIMATED CITY CONTRIBUTION RATE EQUAL TO OR GREATER THAN CORRIDOR MIDPOINT; AUTHORIZATION FOR CERTAIN ADJUSTMENTS.  (a)  This section governs the determination of the city contribution rate in a fiscal year when the estimated city contribution rate is equal to or greater than the corridor midpoint.

(2)  except as provided by Subsection (d) or (f) of this section, greater than the maximum contribution rate for the corresponding fiscal year, the city contribution rate equals the corridor midpoint achieved in accordance with Subsection (c) of this section.
(c)  For purposes of Subsection (b)(2) of this section, the following adjustments shall be applied sequentially to the extent required to decrease the estimated city contribution rate to equal the corridor midpoint:
(1)  first, adjust the actuarial value of assets to the current market value of assets, if making the adjustment causes the city contribution rate to decrease; 
(2)  second, if the payoff year of the legacy liability was accelerated under Section 8E(c) of this Act:
(A)  extend the payoff year of the legacy liability by increasing the legacy liability by the amount of the new liability gain layer to a maximum amount; and
(B)  during the extended period provided by Paragraph (A) of this subdivision, the city shall continue to pay the city contribution amount for the extended period in accordance with the schedule included in the initial risk sharing valuation study, subject to Section 8C(i) or (j) of this Act; and
(3)  third, if the payoff year of a liability loss layer other than the legacy liability was previously accelerated under Section 8E(c) of this Act, extend the payoff year of existing liability loss layers, excluding the legacy liability, by extending the most recent loss layers first, to a payoff year not later than 30 years from the first day of the fiscal year beginning 12 months after the date of the risk sharing valuation study in which the liability loss layer is first recognized.
(d)  If the city contribution rate after adjustment under Subsection (c) of this section is greater than the third quarter line rate, the city contribution rate equals the third quarter line rate.  To the extent necessary to comply with this subsection, the city and the pension board shall enter into a written agreement under Section 3(n) of this Act to increase member contributions and make other benefit or plan changes not otherwise prohibited by applicable federal law or regulations.
(e)  Gains resulting from adjustments made as the result of a written agreement between the city and the pension board under Subsection (d) of this section may not be used as a direct offset against the city contribution amount in any fiscal year.
(f)  If an agreement under Subsection (d) of this section is not reached on or before the 30th day before the first day of the next fiscal year, before the start of the next fiscal year to which the city contribution rate would apply, the pension board, to the extent necessary to set the city contribution rate equal to the third quarter line rate, shall:
(1)  increase member contributions; and
(2)  decrease cost-of-living adjustments.
(g)  If the city contribution rate remains greater than the corridor midpoint in the third fiscal year after adjustments are made in accordance with an agreement under Subsection (d) of this section, in that fiscal year the city contribution rate equals the corridor midpoint achieved in accordance with Subsection (h) of this section.
(h)  The city contribution rate must be set at the corridor midpoint under Subsection (g) of this section by:
(1)  in the risk sharing valuation study for the third fiscal year described by Subsection (g) of this section, adjusting the actuarial value of assets to equal the current market value of assets, if making the adjustment causes the city contribution rate to decrease; and
(2)  under a written agreement entered into between the city and the pension board under Section 3(n) of this Act:
(A)  increasing member contributions; and 
(B)  making any other benefit or plan changes not otherwise prohibited by applicable federal law or regulations.

(3)  group B member who retires on or after January 1, 2005, is equal to the sum of:
(A)  the member's average monthly salary multiplied by the percentage rate accrued under the law in effect on December 31, 2004, for each year of the member's years of credited service in group B that is earned before January 1, 2005;
(B)  the member's average monthly salary multiplied by 1.75 percent for each year of the member's years of credited service in group B during the member's first 10 years of service that is earned on or after January 1, 2005;

(f)  The amount of the monthly normal retirement pension payable to a retired group C member is computed as provided by Section 6 of this Act.
(g)  Notwithstanding any other provision of this Act, the total normal retirement pension of a retired member with credited service in group A, group B, group C, or group D may not exceed 90 percent of the member's average monthly salary.

(i)  A member receiving a normal retirement pension is considered to have resigned and shall be removed from the regular full-time employment rolls of the city or the pension system not later than the day before the member's effective retirement date.
Sec. 10A.  GROUP D MEMBER HYBRID COMPONENT.  (a)  On and after January 1, 2018, in addition to the group D member contributions under Section 8 of this Act, each group D member shall contribute one percent of the member's salary for each biweekly pay period beginning with the member's first full biweekly pay period after the later of January 1, 2018, or the group D member's first date of employment.  The contribution required by this subsection:
(1)  shall be picked up and paid in the same manner and at the same time as group D member contributions required under Section 8(a)(3) of this Act, subject to applicable rules;
(2)  is separate from and in addition to the group D member contribution under Section 8(a)(3) of this Act; and
(3)  is not subject to reduction or increase under Sections 8A through 8F of this Act or a refund under Section 17 of this Act.
(b)  For each biweekly pay period of a group D member's service for which the group D member makes the contribution required under Subsection (a) of this section, the following amounts shall be credited to a notional account, known as a cash balance account, for the group D member:
(1)  the amount of the contributions paid under Subsection (a) of this section for that biweekly pay period; and
(2)  interest on the balance of the group D member's cash balance account determined by multiplying:
(A)  an annual rate that is one-half the pension system's five-year investment return based on a rolling five-fiscal-year basis and net of investment expenses, with a minimum annual rate of 2.5 percent and a maximum annual rate of 7.5 percent, and divided by 26; and
(B)  the amount credited to the group D member's cash balance account as of the end of the biweekly pay period.
(c)  The pension system may not pay interest on amounts credited to a cash balance account but not received by the pension system under Subsection (b) of this section.
(d)  On separation from service, a group D member is eligible to receive only a distribution of the contributions credited to that group D member's cash balance account, without interest, if the group D member has attained less than one year of service while contributing to the cash balance account.  If a group D member attains at least one year of service while contributing to the cash balance account, the group D member is fully vested in the accrued benefit represented by that group D member's cash balance account, including interest.
(e)  In a manner and form prescribed by the pension board, a group D member who terminates employment is eligible to elect to receive the group D member's cash balance account benefit in a lump-sum payment, in substantially equal periodic payments, in a partial lump-sum payment followed by substantially equal periodic payments, or in partial payments from the group D member's cash balance account.
(f)  Contributions may not be made to a group D member's cash balance account for a period that occurs after the date the group D member terminates employment, except that interest at a rate that is not greater than the rate under Subsection (b)(2) of this section, as determined by the pension board, may be credited based on the former group D member's undistributed cash balance account after the date the group D member terminates employment.
(g)  On the death of a group D member or former group D member before the full distribution of the member's cash balance account, the deceased member's cash balance account shall be payable in a single lump-sum payment to:
(1)  the deceased member's surviving spouse;
(2)  if there is no surviving spouse, each designated beneficiary of the deceased member, designated in the manner and on a form prescribed by the pension board; or
(3)  if there is no designated beneficiary, the deceased member's estate.
(h)  The lump-sum payment described by Subsection (g) of this section shall be made within a reasonable time after the pension board has determined that the individual or estate is eligible for the distribution.
(i)  Subject to the other provisions of this section, the pension board may adopt rules necessary to implement this section, including rules regarding the payment of the cash balance account and limitations on the timing and frequency of payments.  All distributions and changes in the form of distribution must be made in a manner and at a time that complies with the Internal Revenue Code of 1986.
Sec. 11.  OPTION-ELIGIBLE PARTICIPANTS.  (a)  In this section, "J&S Annuity" means payment of a normal retirement pension or early retirement pension under one of the options provided by Subsection (b) of this section.
(a-1)  For purposes of this section, an option-eligible participant is:
(1)  a former group A or group B member who terminates employment with the city or the pension system on or after June 30, 2011, and who is eligible to receive a normal retirement pension, provided the member was not married as of the date of the member's termination of employment;
(2)  a former group B member who terminated employment with the city or the predecessor system before September 1, 1997, and who is eligible to receive a normal retirement pension; or
(3)  a former group D member who terminated employment with the city or the pension system and who is eligible to receive a normal retirement pension or an early retirement pension.
(a-2)  The pension board, in its sole discretion, shall make determinations regarding an individual's status as an option-eligible participant.
(a-3)  Before the date an option-eligible participant commences receipt of a benefit, that option-eligible participant must elect, in a manner and at a time determined by the pension board, whether to receive the participant's normal retirement pension or early retirement pension, as applicable, or to have the option-eligible participant's normal retirement pension or early retirement pension, as applicable, paid under one of the options provided by Subsection (b) of this section.  The election may be revoked, in a manner and at a time established by the pension board, not later than the 60th day before the date the participant commences receipt of a benefit.
(b)  The normal retirement pension or early retirement pension may be one of the following actuarially equivalent amounts:
(1)  option 1:  a reduced pension payable to the participant, then on the participant's death one-half of the amount of that reduced pension is payable to the participant's designated survivor, for life;
(2)  option 2:  a reduced pension payable to the participant, then on the participant's death that same reduced pension is payable to the participant's designated survivor, for life; and
(3)  option 3:  a reduced pension payable to the participant, and if the participant dies within 10 years, the pension is paid to the participant's designated survivor for the remainder of the 10-year period beginning on the participant's benefit commencement date.
(c)  If an option-eligible participant who has made the election provided by Subsection (b) of this section dies after terminating employment with at least five years of credited service but before attaining the age required to begin receiving a normal or early retirement pension, the person's designated survivor is eligible for the J&S Annuity provided by the option selected by the option-eligible participant at the time of separation from service.  The benefits first become payable to an eligible designated survivor on the date the option-eligible participant would have become eligible to begin receiving a pension.  If the designated survivor elects for earlier payment, in a time and manner determined by the pension board, the actuarial equivalent of that amount shall be payable at that earlier date.
(d)  A survivor benefit under Subsection (c) of this section or a J&S Annuity is not payable if:
(1)  except as provided by Subsection (e) of this section, an option-eligible participant does not elect one of the J&S Annuity options under Subsection (b) of this section and dies before retirement has commenced;
(2)  an option-eligible participant elects a normal retirement pension or early retirement pension and dies before retirement has commenced; or
(3)  an option-eligible participant dies after retirement has commenced and that option-eligible participant:
(A)  elected a normal retirement pension or early retirement pension;
(B)  did not make a valid election under Subsection (b) of this section; or
(C)  made an election that is void.
(e)  An option-eligible participant described by Subsection (a-1)(3) of this section who did not elect one of the J&S Annuity options under Subsection (b) of this section is considered to have elected a J&S Annuity option under Subsection (b)(1) of this section and to have designated the participant's surviving spouse as the optional annuitant if the participant:
(1)  was not in service with the city or the pension system at the time of the participant's death;
(2)  is survived by a surviving spouse; and
(3)  dies before the participant's retirement has commenced.
(f)  If the option-eligible participant described by Subsection (e) of this section has no surviving spouse, a survivor benefit or J&S Annuity is not payable.  If a J&S Annuity is paid under Subsection (e) of this section, a survivor benefit is not payable under this subsection or under Section 14 of this Act.
(g)  If Subsection (d) of this section would otherwise apply to prohibit the payment of a survivor benefit or J&S Annuity, but there is one or more dependent children of the deceased option-eligible participant, the provisions of Section 14 of this Act control the payment of survivor benefits to the dependent child or children.  The pension system may not pay both a J&S Annuity under this section and a survivor benefit under Section 14 of this Act with respect to any option-eligible participant.  If a J&S Annuity is paid under Subsection (e) of this section, a survivor benefit is not payable.
(h)  If an option-eligible participant has previously elected a J&S Annuity for a previous period of service, no benefits have been paid under that previous election, and the option-eligible participant terminates employment on or after January 1, 2012, the previous election is void and the option-eligible participant shall make an election under Subsection (b) of this section to apply to all periods of service.
(i)  If a former group B member with service before September 1, 1997, was rehired in a covered position and converted the group B service covered by a J&S Annuity to group A service, and that member terminates employment on or after January 1, 2012, and is not an option-eligible participant at the time of the member's subsequent termination, the previous election is void and survivor benefits for an eligible survivor, if any, are payable as provided by Section 14 of this Act, provided benefits were not paid under the previous election.
(j)  If an option-eligible participant who elects a J&S Annuity under this section designates the participant's spouse as a designated survivor and the marriage is later dissolved by divorce, annulment, or a declaration that the marriage is void before the participant's retirement, the designation is void unless the participant reaffirms the designation after the marriage was dissolved.
(k)  A J&S Annuity payable to a designated survivor of a retired option-eligible participant is effective on the first day of the month following the month of the option-eligible participant's death and ceases on the last day of the month of the designated survivor's death or on the last day of the month in which the survivor otherwise ceases to be eligible to receive a J&S Annuity.
Sec. 12.  DEFERRED RETIREMENT OPTION PLAN.  (a)  In this section:
(1)  "DROP" means the deferred retirement option plan established under Chapter 358, Acts of the 48th Legislature, Regular Session, 1943 (Article 6243g, Vernon's Texas Civil Statutes), and reenacted and continued under this Act.
(2)  "DROP account" means a notional account established for a DROP participant that is used solely as an accounting convention to aid in the computation of the DROP participant's DROP benefit.  The DROP account may only be used for accounting purposes, and there is no actual separation of assets of the pension fund before the distribution of the DROP participant's DROP benefit.
(3)  "DROP benefit" means a DROP participant's total DROP account balance at the time the DROP participant terminates employment.
(4)  "DROP election date" means the date the pension system receives a member's election to participate in the DROP in the manner and form determined by the pension system and approved by the pension board.
(5)  "DROP entry date" means the date a member ceases to earn service credit and begins earning credit for the member's DROP account, which is the later of the date the member is eligible to participate in the DROP, the date requested by the member, or October 1, 1997, as approved by the pension board.  The DROP entry date is the first day of a month and is determined by the normal retirement eligibility requirements of this Act or of Chapter 358, Acts of the 48th Legislature, Regular Session, 1943 (Article 6243g, Vernon's Texas Civil Statutes), as applicable, in effect on the requested DROP entry date.  A member who enters DROP on or after January 1, 2005, may not have a DROP entry date that occurs before the date the pension system receives the member's request to participate in DROP.
(6)  "DROP participant" means a pension system member who is participating in the DROP.
(b)  A member who is eligible to receive a normal retirement pension under this Act and who is in active service with the city or the pension system, or a person who is eligible to receive a normal retirement pension under this Act and who has been separated from service for less than 30 days and has not otherwise been granted a pension or benefit, may file with the pension system an election to participate in the DROP and receive a DROP benefit under procedures established by the pension board.  An election to participate in the DROP is irrevocable except as provided by Subsection (j) of this section.
(b-1)  Notwithstanding Subsection (b) of this section, for DROP participation beginning on or after January 1, 2005, a member must meet the normal retirement eligibility requirements under Section 10(b) or (c) of this Act to be eligible to elect to participate in DROP.  This subsection does not apply to a member who:
(1)  met the eligibility requirements under Section 10(b) of this Act in effect before January 1, 2005; or
(2)  before January 1, 2005, had at least five years of credited service and a combination of years of age and years of credited service, including parts of years, the sum of which equaled or was greater than 68.
(c)  A member who is required to make payments to the pension system to purchase service or to convert service is eligible to participate in the DROP only to the extent that the member is eligible to participate in the DROP without regard to the service covered by the payment obligation, but must complete the obligation.  If the payment obligation is not fully met, the member's participation in the DROP is determined as though the payment obligation was not entered into.  A member who is participating in the DROP may not change membership from one group to another group, convert service from one group to another group, purchase service credit, or make a claim to purchase military service.
(d)  Credited service and normal retirement benefits cease to accrue on the day preceding the member's DROP entry date.  The period of a member's DROP participation, unless revoked as provided by Subsection (j) of this section, begins on the DROP participant's DROP entry date and ends on the date of the DROP participant's last day of active service with the city or the pension system.  On the first day of the month following the month in which the pension board approves the member's DROP election, the DROP election becomes effective and the pension board shall establish a DROP account for the DROP participant.  For each month during the period of DROP participation before a DROP participant's termination of employment, the following amounts shall be credited to the DROP participant's DROP account, including prorated amounts for partial months of service:
(1)  an amount equal to what would have been the DROP participant's monthly normal retirement benefit if the DROP participant had retired on the DROP participant's DROP entry date, except that the monthly amount shall be computed based on the DROP participant's credited service and average monthly salary as of the DROP entry date and the benefit accrual rates and maximum allowable benefit applicable on the DROP election date, with the cost-of-living adjustments payable under Subsection (s) of this section, if any, that would apply if the DROP participant had retired on the DROP participant's DROP entry date; and
(2)  subject to Subsection (d-1) of this section,  interest on the DROP participant's DROP account balance computed at a rate determined by the pension board and compounded at intervals designated by the pension board, but at least once in each 13-month period.
(d-1)  Beginning January 1, 2018, the pension board shall establish the interest rate applicable under Subsection (d)(2) of this section as of January 1 of each year at a rate:
(1)  except as provided by Subdivision (2) of this subsection, equal to half the pension system's five-year investment return based on a rolling five-fiscal-year basis and net of investment expenses; and
(2)  that may not be less than 2.5 percent or more than 7.5 percent.
(e)  The monthly amount credited under Subsection (d)(1) of this section may not include any amount that is intended to help defray an increase in group medical insurance costs as described by Section 15(a) of this Act.  In any year in which a supplemental payment is made to retirees under Section 15(b) of this Act, an amount equal to the amount of the supplemental payment that would have been made to the DROP participant if the DROP participant had retired on the DROP entry date shall be credited to the DROP participant's DROP account.
(f)  The period for credits to a DROP participant's DROP account includes each month beginning with the DROP participant's DROP entry date through the date the DROP participant terminates employment with the city or the pension system.  Credits may not be made to a DROP participant's DROP account for a period that occurs after the date the DROP participant terminates employment, except that interest at a rate determined by the pension board may be paid on the person's undistributed DROP account balance after the date the person terminates employment.  A DROP participant must pay required contributions to the pension system for all time in DROP that would otherwise constitute service in order to receive allowable credits to the DROP participant's DROP account.
(g)  A DROP participant who terminates employment is eligible to elect to receive the DROP participant's DROP benefit in a lump sum, in substantially equal periodic payments, in a partial lump sum followed by substantially equal periodic payments, or in partial payments from the participant's DROP account, in a manner and form determined by the pension board.  The pension board may establish procedures concerning partial payments under this subsection, including limitations on the timing and frequency of those payments.  A participant who elects partial payments may elect to receive the participant's entire remaining DROP account balance in a single lump-sum payment.  The pension board shall determine a reasonable time for lump-sum and periodic payments of the DROP benefit.   All distributions and changes in the form of distribution must be made in a manner and at a time that complies with that provision of the Internal Revenue Code of 1986, as amended.
(h)  If a DROP participant dies before the full distribution of the DROP participant's DROP account balance, the undistributed DROP account balance shall be distributed to the DROP participant's surviving spouse, if any, in a lump-sum payment within a reasonable time after the pension board has determined that the surviving spouse is eligible for the distribution.  If there is no surviving spouse, each beneficiary of the DROP participant, as designated in the manner and on a form established by the pension board, is eligible to receive the beneficiary's applicable portion of the deceased DROP participant's undistributed DROP account balance in a lump-sum payment within a reasonable time after the pension board has determined that the beneficiary is eligible for the distribution.  If no beneficiary is designated, the undistributed DROP account balance shall be distributed to the deceased participant's estate.
(i)  A DROP participant is ineligible for disability benefits provided by this Act.
(j)  An election to participate in the DROP is irrevocable, except that:
(1)  if a DROP participant is approved for a service disability pension, the DROP participant's DROP election is automatically revoked; and
(2)  if a DROP participant dies, the surviving spouse, if any, or the beneficiary, if any, may elect to revoke the DROP participant's DROP election, at a time and in a manner determined by the pension board, only if the revocation occurs before a distribution from the DROP participant's DROP account or the payment of a survivor benefit under this Act or Chapter 358, Acts of the 48th Legislature, Regular Session, 1943 (Article 6243g, Vernon's Texas Civil Statutes).
(k)  On revocation of a DROP election under Subsection (j) of this section, the DROP account balance becomes zero, and a distribution of DROP benefits may not be made to the participant, the participant's surviving spouse, or the participant's beneficiaries.  In the event of revocation, the benefits based on the participant's service are determined as if the participant's DROP election had never occurred.
(l)  Under a rule adopted by the pension board under this section, the surviving spouse of a deceased member or, if the member has no surviving spouse, the designated beneficiary of the deceased member may make the DROP election that the deceased member would have been eligible to make the day before the member's death and may receive the DROP distribution in a lump sum within a reasonable time after the pension board has determined that the surviving spouse or designated beneficiary is eligible for the distribution.  A DROP election by the surviving spouse or designated beneficiary under this subsection may not be made after the sixth month after the date of the member's death.  An election may not be made under this subsection if a survivor benefit or other distribution has been made with respect to the deceased member.  Notwithstanding any other provision, an election made under this subsection is irrevocable.
(m)  If an unanticipated actuarial cost occurs in administering the DROP, the pension board, on the advice of the pension system actuary, may take action necessary to mitigate the unanticipated cost, including refusal to accept additional elections to participate in the DROP.  The pension system shall continue to administer the DROP for the DROP participants participating in the DROP before the date of the mitigating action.
(n)  A former DROP participant who is rehired by the city or the pension system following termination of employment is not eligible to participate in the DROP.
(o)  Except as provided by Subsection (o-1) of this section, on termination of employment, a DROP participant shall receive a normal retirement pension under Section 10 of this Act or under Section 11, 22A, or 24 of Chapter 358, Acts of the 48th Legislature, Regular Session, 1943 (Article 6243g, Vernon's Texas Civil Statutes), as those sections read on the day preceding the participant's DROP entry date, as applicable, except that the credited service under that section is the member's credited service as of the day before the member's DROP entry date, the benefit accrual rate applicable to the credited service shall be the benefit accrual rate in effect on the member's DROP election date, the maximum allowable benefit shall be the maximum allowable benefit in effect on the member's DROP election date, and the member's average monthly salary is the average monthly salary determined as of the later of the member's DROP entry date or January 1, 2005, as applicable.  The DROP participant's normal retirement pension is increased by any cost-of-living adjustments applied to the monthly credit to the member's DROP account under Subsection (d)(1) of this section during the member's participation in the DROP.  Cost-of-living adjustments applicable to periods after the date of the DROP participant's termination of employment are based on the DROP participant's normal retirement pension computed under this subsection or Subsection (o-1) of this section, as applicable, excluding any cost-of-living adjustments.
(o-1)  On termination of employment, and before any benefit or DROP payment, a DROP participant who is an option-eligible participant shall make the required election under Section 11 of this Act.  If the option-eligible participant elects a J&S Annuity, the DROP account, including all DROP credits, shall be recalculated from the DROP entry date to termination of employment as provided by Subsection (o) of this section as if the J&S Annuity was selected to be effective as of the DROP entry date.
(p)  If a DROP election is not revoked under Subsection (j) of this section, the survivor benefit payable to an eligible survivor of a deceased DROP participant under Section 14 of this Act is computed as a percentage of the monthly ordinary disability pension that the member would have been eligible to receive had the member suffered a disability the day before the member's DROP entry date, except that the ordinary disability pension is computed based on the DROP participant's credited service as of the day before the DROP participant's DROP entry date, the benefit accrual rate applicable to the credited service as of the DROP participant's DROP election date, and the DROP participant's average monthly salary as of the later of the DROP participant's DROP entry date or January 1, 2005, as applicable.  A surviving spouse, if any, of a DROP participant who dies from a cause directly resulting from a specific incident in the performance of the DROP participant's duties for the city or the pension system is ineligible to receive enhanced survivor benefits under Section 14(c) of this Act unless the DROP election is revoked under Subsection (j)(2) of this section and the surviving spouse receives a survivor benefit as otherwise provided by this subsection.
(q)  The pension board may adopt rules for the implementation and operation of the DROP, including rules regarding the payment of DROP benefits.
(r)  Except as provided by Subsection (s) of this section, the pension system may not credit a DROP account with a cost-of-living adjustment percentage on or after February 1, 2018.
(s)  On or after February 1, 2018, and for future credit only, the pension system shall credit a cost-of-living adjustment percentage, not compounded, to the DROP account of a DROP participant who was at least 62 years of age as of January 1 of the year in which the increase is made.
(t)  The pension board may establish deadlines for the submission of any information, document, or other record pertaining to DROP.
Sec. 13.  DISABILITY PENSIONS.  (a)  A member who has completed five or more years of credited service and who becomes disabled is eligible, regardless of age, for an ordinary disability retirement and shall receive a monthly disability pension computed in accordance with Section 10(d) of this Act.
(b)  A member who is disabled by reason of a personal injury sustained or a hazard undergone as a result of, and while in the performance of, the member's employment duties at some definite place and at some definite time on or after the date of becoming a member, without serious and wilful misconduct on the member's part, is eligible for a service disability retirement and shall receive a monthly disability pension equal to the greater of:
(1)  the monthly normal retirement pension computed under Section 10(d) of this Act; or
(2)  20 percent of the member's monthly salary on the date the injury occurred or the hazard was undergone.
(c)  In addition to the monthly disability pension under Subsection (b)(2) of this section, a group A member shall receive one percent of the salary under Subsection (b)(2) of this section for each year of credited service.  The total disability pension computed under Subsection (b)(2) of this section may not exceed the greater of:
(1)  40 percent of that monthly salary; or
(2)  the monthly normal retirement pension computed in accordance with Section 10(d) of this Act.
(d)  A disability pension may be granted under this section to a member only if the member is unable to perform work or services as an employee due to the disability.  A member who is granted a disability pension is considered to have resigned and shall be removed from the employment rolls of the city or the pension system not later than the last day of the month in which the disability pension is approved.
(e)  A person retired for disability under this Act or a person receiving survivor benefits as a disabled dependent child under this Act shall file an annual report of employment activities and earnings with the pension board.  The pension board shall establish the form of the report and the time for filing the report.  If the amount of the earnings added to the disability pension being received by the member exceeds the amount of the monthly salary of the member at the time of the member's separation from service, as adjusted annually by cost-of-living adjustments equal to the percentage change in the Consumer Price Index for All Urban Consumers for the preceding year, as determined by the United States Department of Labor, but not to exceed the cost-of-living adjustment provided by Section 10(h) of this Act, the pension board may reduce the amount of the pension.  A disability pension recipient is not required to submit the annual affidavit of employment activities and earnings after the recipient reaches:
(1)  the date on which the recipient would be eligible to retire, if Section 10(b) or (c) applied to the recipient; or
(2)  65 years of age.
(f)  A member may not receive a disability pension and a deferred or normal retirement pension at the same time.  If a member who has at least five years of credited service is eligible for a disability pension, the member's disability ceases to exist, and the member does not return to work for the city, the member is eligible to receive a deferred or normal retirement pension, beginning on the later of the member's effective retirement date or the date the disability ceases.  The deferred or normal retirement pension is based on actual credited service up to the time of disability and is computed based on the schedule of benefits and provisions in effect on the person's last day of credited service.
(g)  A former member who is retired for disability or a person receiving survivor benefits as a disabled dependent child under this Act is subject at all times to reexamination by the pension board and shall submit to an examination the pension board requires.  If the disability retiree or dependent child who is receiving survivor benefits as a disabled child refuses to submit to a required examination, the pension board may order that payments be suspended, up to and including discontinuation of the disability pension or survivor benefit.  If the pension board determines that a member who has been retired for a disability or a person who is receiving survivor benefits as a disabled dependent child recovers so that the member or person is able to perform the usual and customary duties formerly handled by the member or person or other full-time duties that could be performed by the member or person, the pension board shall suspend or discontinue pension or survivor benefit payments.
(h)  The result of an examination, report by a physician, or report of employment activities and earnings shall be considered by the pension board in determining whether the benefits shall be continued, increased if less than the maximum provided, decreased, or discontinued.  The pension board may reduce, suspend, or discontinue all benefits to a person receiving benefits under this section who, after notice from the pension board:
(1)  fails to appear for a required examination;
(2)  fails to file a report of employment activities and earnings or another related report requested by the pension board; or
(3)  files a materially false or misleading report of employment activities and earnings or examination result or other report, as determined by the pension board.
(i)  To apply for a disability pension, a person must be a member or a former member whose separation from service occurred not more than 30 days before the date the pension system receives the person's request to apply for a disability pension as a result of a disability that arose during employment, except that a member may not apply for a disability pension after the sixth month after the date of the member's last day of credited service.
Sec. 14.  SURVIVING SPOUSE AND DEPENDENT CHILD MONTHLY ALLOWANCE.  (a)  Except as provided by Section 11 or 12 of this Act, the pension board shall order survivor benefits to be paid to an eligible survivor in the form of a monthly allowance under this section if:
(1)  a member or former member of group A or group B dies from any cause after the completion of five years of credited service with the city or the pension system;
(2)  while in the service of the city or the pension system, a member dies from any cause directly resulting from a specific incident in the performance of the member's duty;
(3)  a member of group A or group B dies after the date the member retires on a pension because of length of service or a disability and the member leaves an eligible survivor; or
(4)  a member of group D dies from any cause after the completion of five years of credited service with the city or the pension system if the member on the date of the member's death was still in service with the city or the pension system.
(b)  A surviving spouse of a member described by Subsection (a)(1) or (4) of this section who dies while still in service with the city or the pension system is eligible for a sum equal to the following applicable percentage of the retirement benefits to which the deceased member or former member would have been eligible had the member been totally disabled with an ordinary disability at the time of the member's last day of credited service:
(1)  80 percent, if the member's death occurs on or after the year 2017 effective date and the spouse was married to the member for at least one continuous year as of the member's date of death, except that the allowance payable to the surviving spouse may not be less than $100 a month; or
(2)  50 percent, if the member's death occurs on or after the year 2017 effective date and the spouse was married to the member for less than one continuous year as of the date of the member's death.
(b-1)  A surviving spouse of a former member described by Subsection (a)(1) of this section who dies on or after the year 2017 effective date while not in the service of the city or the pension system and before the member's retirement commenced, is eligible for a sum equal to 50 percent of the deceased former member's normal accrued pension at the time of the deceased former member's last day of credited service.  Benefits under this subsection first become payable on the date the former member would have become eligible to begin receiving a pension.  If the surviving spouse elects for earlier payment, in a time and manner determined by the pension board, the actuarial equivalent of that amount shall be payable at that earlier date.
(c)  A surviving spouse of a member described by Subsection (a)(2) of this section who dies from a cause directly resulting from a specific incident in the performance of the member's duty with the city or the pension system, without serious or wilful misconduct on the member's part, is eligible for a sum equal to 80 percent of the deceased member's final average salary.
(d)  A surviving spouse of a retiree described by Subsection (a)(3) of this section who dies after having received retirement benefits is eligible for a sum equal to the following applicable percentage of the retirement benefits being received at the time of the retiree's death, including any applicable cost-of-living adjustment in the survivor benefit under Section 10(h) of this Act computed based on the unadjusted normal retirement pension of the deceased retiree:
(1)  80 percent, if the retiree's death occurs on or after the year 2017 effective date and the retiree separated from service with the city or pension system before the year 2017 effective date;
(2)  80 percent, if the retiree's death occurs on or after the year 2017 effective date and the retiree separated from service with the city or pension system on or after the year 2017 effective date, provided the surviving spouse was married to the retiree at the time of the retiree's death and for at least one continuous year as of the date of the retiree's separation from service; or
(3)  50 percent, if both the retiree's separation from service and death occur on or after the year 2017 effective date and the surviving spouse was married to the retiree at the time of the retiree's death for less than one continuous year as of the date of the retiree's separation from service.
(e)  If there is a surviving spouse, each dependent child shall receive a survivor benefit equal to 10 percent of the pension the member would have received if the member had been disabled at the time of death up to a maximum of 20 percent for all dependent children, except that if the total amount payable to the surviving spouse and dependent children is greater than 80 percent of the benefit the member would have received, the percentage of benefits payable to the surviving spouse shall be reduced so that the total amount is not greater than 80 percent of the benefit the member would have received, and the reduction shall continue until the total amount payable to the surviving spouse and dependent child, if any, would not be greater than 80 percent of the benefit the member would have received.
(f)  If there is no surviving spouse, each dependent child is eligible to receive a survivor benefit equal to 50 percent of the amount of the surviving spouse benefit had there been a surviving spouse, not to exceed 100 percent of the surviving spouse benefit for all dependent children in the aggregate.
(g)  Benefits for a dependent child are payable to the guardian of the child, except that the pension board may approve the payment of benefits to a child who is at least 18 years of age.  As used in this subsection, "guardian" means the person who has the primary responsibility for a child's care and support, including the surviving parent, a legal guardian, a managing conservator, or any other person with a similar legal relationship to the child.
(h)  If a retiree dies and there is no eligible survivor, the retiree's spouse, if any, or if there is no spouse, the retiree's estate, is eligible to receive a lump-sum payment of the unamortized balance of the retiree's accrued employee contributions, if any, other than contributions after the DROP entry date, as determined by an amortization schedule and method approved by the pension board.  A pension payable to a retiree ceases on the last day of the month of the retiree's death.  A survivor benefit payable to an eligible survivor is effective on the first day of the month following the month of the retiree's death and ceases on the last day of the month of the eligible survivor's death or on the last day of the month in which the survivor otherwise ceases to be eligible to receive a survivor's benefit.
Sec. 15.  INCREASE IN BENEFITS.  (a)  In addition to the postretirement increases under Section 10(h) of this Act, the pension board may increase annuities payable under this Act by an amount that does not exceed the annual increase in the amount of premiums being paid under a group insurance program provided for retirees of the city.
(b)  The pension board may distribute a supplemental payment to all retirees and eligible survivors who are receiving annuities as of January 1 of the year in which the supplemental payment is made.  The supplemental payment shall be credited to DROP participants who are participating in DROP as of January 1 of the year in which the supplemental payment is made, if the pension board's actuary determines that as of the end of any fiscal year:
(1)  the value of the pension system's assets exceeds the amount of the pension system's accrued liability;
(2)  the pension system has met the actuarial investment assumption for the previous fiscal year; and
(3)  the issuance of the supplemental check will not cause the city's contribution rate to increase.
(c)  A person may not receive more than one supplemental payment as a result of the person's status as:
(1)  a retiree and eligible survivor; or
(2)  a DROP participant and eligible survivor.
(d)  A pension benefit or allowance provided by this article may be increased if:
(1)  a qualified actuary selected by the pension board determines that the increase cannot reasonably be considered to jeopardize the pension system's ability to pay any existing benefit;
(2)  the increase is approved by the pension board and the city in a written agreement as provided by Section 3(n) of this article; and
(3)  the increase does not deprive a member or retiree, without the written consent of the member or retiree, from receiving the immediate or deferred retirement benefit that the member or retiree was eligible to receive under this article before the increase.
Sec. 16.  LUMP-SUM BENEFIT PAYMENT.  (a)  Notwithstanding any other provision of this Act, the pension board may pay to a member, deferred participant, eligible survivor, alternate payee, or beneficiary in a lump-sum payment the present value of any benefit payable to such a person that is less than $20,000 instead of paying any other benefit payable under this Act.  If the lump-sum present value of the benefit is at least $1,000 but less than $20,000, the pension board may make a lump-sum payment only on written request by the member, deferred participant, eligible survivor, alternate payee, or other beneficiary.  The pension board shall make any payment under this subsection as soon as practicable after eligibility under this section has been determined by the pension board.
(b)  The pension board shall adopt actuarial assumptions, including an interest rate, to be used in determining lump-sum present values and amounts distributable under this section.
(c)  If the pension board determines that available resources in the pension fund are inadequate to make lump-sum payments, payments under this section shall be made monthly in amounts the pension board determines.
(d)  Payments under this section may not be made for a benefit that was being paid by the predecessor system or this pension system.
(e)  A member who is reemployed by the city or the pension system and who has at least two years of continuous credited service after reemployment may reinstate service for which the member received a lump-sum payment under this section by paying into the pension fund the amount of the lump-sum payment, plus interest on that amount at the applicable assumed rate of return, not compounded, from the date the lump-sum payment was made to the member until the date of repayment to the pension fund.
(f)  The actuarial value of a lump-sum payment is determined as of the last day of credited service or September 1, 1995, whichever is later.
Sec. 17.  TERMINATION OF EMPLOYMENT; DEATH; REEMPLOYMENT.  (a)  A member who terminates employment with the city involuntarily due to a reduction in workforce, as determined by the pension board, before the member becomes eligible for a normal retirement pension or attains five years of credited service, is eligible to leave the person's contributions in the pension fund until the first anniversary of the date of termination.  If during that period the person is reemployed by the city and has not withdrawn the person's contributions, all rights and service credit as a member shall be immediately restored without penalty.  If reemployment with the city does not occur before the first anniversary of the date of termination, all payments made by the person into the pension fund by salary deductions or other authorized contributions shall be refunded to the person without interest.  If the person is subsequently reemployed, the person may have credit restored, subject to the provisions applicable at the time of reemployment.
(b)  A member who leaves employment voluntarily, before becoming eligible for a normal retirement or disability pension, ceases to be a member of the pension system and shall be refunded all eligible payments made by the member into the pension fund by salary deductions or other authorized contributions, without interest, subject to this section.
(c)  A former member of group A or group B whose employment is terminated for a reason other than death or receipt of a retirement or disability pension after the completion of five years of credited service may elect, in a manner determined by the pension board, to receive a deferred retirement pension that begins on the member's effective retirement date after the member attains the eligibility requirements for normal retirement under Section 10 of this Act as it existed on the member's last day of credited service.  The amount of monthly benefit shall be computed in the same manner as for a normal retirement pension, but based on average monthly salary and credited service as of the member's last day of credited service and subject to the provisions of this Act or Chapter 358, Acts of 48th Legislature, Regular Session, 1943 (Article 6243g, Vernon's Texas Civil Statutes), in effect on the former member's last day of credited service.
(c-1)  A former member of group D whose employment is terminated for a reason other than death or receipt of a retirement or disability pension after the completion of five years of credited service may elect, in a manner determined by the pension board, to receive a deferred normal retirement pension that begins on the former member's effective retirement date after the member attains 62 years of age.  The amount of a monthly benefit under this subsection shall be computed in the same manner as a normal retirement pension, except the benefit shall be based on the average monthly salary and credited service of the former member as of the former member's last day of credited service and subject to the provisions of this Act in effect on the former member's last day of credited service.
(c-2)  A former member of group D whose employment is terminated for a reason other than death or receipt of a retirement or disability pension and who has met the minimum years of credited service to receive an early reduced retirement pension under Section 10(e) of this Act on attaining the required age, may elect, in a manner determined by the pension board, to receive a deferred early retirement pension that begins on the former member's effective retirement date after the member attains the required age under Section 10(e) of this Act.  The amount of monthly benefit shall be computed in the same manner as for an early retirement pension under Section 10(e) of this Act, except that the benefit shall be based on the average monthly salary and credited service of the former member as of the former member's last day of credited service and subject to the provisions of this Act in effect on the former member's last day of credited service.
(d)  If a member dies while still employed by the city, whether eligible for a pension or not, and Sections 12 and 14 of this Act do not apply, all of the member's rights in the pension fund shall be satisfied by the refund to the member's spouse, if any, or if there is no spouse, to the member's estate, of all eligible payments, if any, made by the member into the pension fund, without interest.
(e)   If there is no eligible survivor of the former member, all of the former member's rights in the pension fund shall be satisfied by the refund to the former member's spouse, if any, or if there is no spouse, to the former member's estate, of all eligible payments made by the former member into the pension fund by way of employee contributions, without interest.
(f)  This Act does not change the status of any former member of the predecessor system whose services with the city or the pension system were terminated under Chapter 358, Acts of the 48th Legislature, Regular Session, 1943 (Article 6243g, Vernon's Texas Civil Statutes), except as otherwise expressly provided.  Refunds of contributions made under this section shall be paid to the departing member, the member's spouse, or the member's estate on written request and approval by the pension board in a lump sum, except that if the pension board determines that funds are insufficient to justify the lump-sum payment, the payment shall be refunded on a monthly basis in amounts determined by the pension board.
(g)  If a deferred participant is reemployed by the city or the pension system before receiving a deferred retirement pension or if a retiree is reemployed by the city or the pension system, Subsections (h) and (j) of this section apply to the computation of the member's pension following the member's subsequent separation from service if the member was a member on or after May 11, 2001, and is not otherwise subject to Subsection (q) of this section.
(h)  If a member described in Subsection (g) of this section accrues not more than two years of continuous credited service after reemployment:
(1)  the portion of the member's deferred or normal retirement pension attributable to the member's period of credited service accrued before the date of the member's original or previous separation from service is computed on the basis of the applicable provisions of this Act or the predecessor system that were in effect on the member's last day of credited service for the original or previous period of credited service;
(2)  the portion of the member's deferred or normal retirement pension attributable to the member's period of credited service accrued after the date of the member's reemployment by the city or the pension system is computed on the basis of the applicable provisions of this Act or the predecessor system in effect on the member's last day of credited service for the subsequent period of credited service; and
(3)  the disability pension or survivor benefit attributable to the member's period of credited service accrued both before the date of the member's original or previous separation from service and after the date of the member's reemployment by the city or the pension system is computed on the basis of the applicable provisions of this Act or the predecessor system that were in effect on the member's last day of credited service for the original or previous period of credited service.
(i)  Subject to Subsection (l) of this section, the disability pension or survivor benefit under Subsection (h)(3) of this section is computed by adding the following amounts:
(1)  the amount of the benefit derived from the member's credited service accrued after the date of reemployment based on the benefit accrual rate in effect on the member's last day of original or previous credited service in the group in which the member participated on the member's last day of subsequent credited service; and
(2)  the amount of the benefit the member, beneficiary, or eligible survivor was eligible to receive based on the member's original or previous credited service and the provisions in effect on the member's last day of original or previous credited service.
(j)  If a member described by Subsection (g) of this section accrues more than two years of continuous credited service after reemployment, for purposes of future payment only, a deferred retirement pension, normal retirement pension, disability pension, or survivor benefit is computed on the basis of the applicable provisions of this Act or the predecessor system in effect on the member's last day of credited service for the subsequent service.
(k)  Notwithstanding any other provision of this Act, if a retiree is reemployed by the city or the pension system and becomes a member, the retiree's pension under this Act ceases on the day before the date the retiree is reemployed.  Payment of the pension shall be suspended during the period of reemployment and may not begin until the month following the month in which the reemployed retiree subsequently terminates employment.  On subsequent separation, benefits payable are computed under Subsections (h) and (j) of this section, as applicable.  If the reemployed retiree receives any pension during the period of reemployment, the retiree shall return all of the pension received during that period to the pension system not later than the 30th day after the date of receipt.  If the reemployed retiree does not timely return all of the pension, the pension board shall offset the amount not returned against the payment of any future retirement pension, disability pension, DROP balance, or survivor benefit payable on behalf of the reemployed retiree, plus interest on the disallowed pension at the applicable assumed rate of return, not compounded, from the date the reemployed retiree received the disallowed pension to the date of the offset on the disallowed pension.
(l)  Except as provided by Section 14 of this Act, if a member is covered by Subsection (h) of this section and has made an election or was eligible to make an election under Section 11 of this Act or an optional annuity election under Section 29, Chapter 358, Acts of the 48th Legislature, Regular Session, 1943 (Article 6243g, Vernon's Texas Civil Statutes), or has received a pension computed on the basis of an optional annuity election, the optional annuity election, including any designation of an eligible designated survivor, governs the payment of any pension or benefit for the period of service covered by the optional annuity election, and no other survivor benefit is payable for that period of service.  If a member meets the requirements of Subsection (j) of this section and has made an optional annuity election or has received a pension computed on the basis of an optional annuity election, the optional annuity election, including any designation of an eligible designated survivor, shall control the payment of any pension or benefit, and no other survivor benefit is payable unless the member elects, not later than the 90th day after the date of the separation of employment and before payment of a pension, to revoke the optional annuity election for future payment of benefits.  If revocation occurs, any survivor benefit is paid under Subsection (j) of this section.
(m)  If a member's service is terminated before the member has completed five years of service for any reason other than death, a city workforce reduction as described by Subsection (a) of this section, or a service disability, the member:
(1)  forfeits the member's accrued pension, service and credited service, and any benefit payable under this Act; and
(2)  shall be refunded, on written request, the amount paid by the member into the pension fund as employee contributions, without interest, in full satisfaction of the member's rights under this Act.
(n)  This section does not allow retroactive payment of any benefits or other amounts under this section to any member, retiree, deferred participant, beneficiary, eligible survivor, estate, or other person or entity.
(o)  After separation from service, a member is subject to the schedule of benefits and provisions in effect on the member's last day of credited service, except as otherwise expressly provided by this Act.
(p)  A person receiving or eligible for a survivor benefit under this Act is subject to the schedule of benefits and provisions in effect on the last day of credited service of the deceased participant for whom the person is claiming survivor status, except as otherwise expressly provided by this Act.
(q)  Subsections (g) through (l) of this section do not apply to the calculation of any benefit for or attributable to the period of service following:
(1)  the employment or reemployment of a member hired or rehired on or after January 1, 2005; or
(2)  the reemployment of a deferred retiree or retiree who is reemployed in a pension system covered position before January 1, 2005, but for a period of two years or less of continuous credited service.
(r)  If a deferred retiree or retiree subject to Subsection (q)(2) of this section is reemployed in a pension system covered position, the retiree's pension due on the retiree's subsequent retirement shall be computed as follows:
(1)  the portion of the retiree's pension attributable to the retiree's periods of credited service that accrued before the retiree's reemployment shall be calculated on the basis of the schedule of benefits for retiring members that was in effect at the time of the member's previous termination or terminations of employment; and
(2)  the portion of the member's pension attributable to the member's period of credited service that accrued after the member's reemployment shall be calculated on the basis of the schedule of benefits for retiring members that is in effect at the time of the member's subsequent retirement.
(s)  The computation under Subsection (r) of this section may not result in a lower pension benefit amount for the previous service of the retiree than the pension benefit amount the retiree was eligible to receive for the retiree's previous service before the date of reemployment.
Sec. 18. MILITARY SERVICE CREDIT.  (a)  Notwithstanding any other provision of this Act, contributions, benefits, and service with respect to service in the uniformed services, as defined in 38 U.S.C. Section 4301 et seq., of a member who is eligible for reemployment rights with the city under 38 U.S.C. Section 4301 et seq. for the service shall be provided in accordance with Section 414(u), Internal Revenue Code of 1986, as amended.
(b)  The city shall make the employer contributions to the pension fund for the employee's membership for each month of service credit in which the member is engaged in service in a uniformed service described by Subsection (a) of this section, based on the member's rate of monthly compensation as of the date the member left the member's position.
(c)  A member who has active military service for which the member is not eligible for reemployment rights with the city under 38 U.S.C. Section 4301 et seq. may receive credited service for the active military service on proper action by the pension board if the member:
(1)  has completed at least five years of credited service in the pension system;
(2)  obtains, at the member's cost, a report approved by the pension board of the actuarial cost of the service for which the member claims credit, with service time expressed as a number of whole months; and
(3)  pays the actuarially determined cost of the service under Subdivision (2) of this subsection as approved by the pension board, plus all administrative costs associated with crediting the service, if any, plus six percent interest from the due date of the amounts until the date full payment is made to the pension fund, with the payments made before:
(A)  the fifth anniversary of the date the claim for service is made, if a member does not terminate employment before the fifth anniversary; or
(B)  the 60th day after the date employment is terminated, if a member terminates employment before the fifth anniversary of the date the claim for service is made.
(d)  The military service credited under Subsection (c) of this section:
(1)  may not exceed a total of 60 months; and
(2)  may be claimed as service solely in the group in which the member participates at the time the member claims the service.
Sec. 19.  MULTIPLE PENSIONS.  (a)  The pension board may authorize a member to make a one-time irrevocable election, on a date and in a manner established by the pension board, to cease to be a member of the pension system and, for future service only, to become a member of the retirement system governed by Article 6243e.2(1), Revised Statutes, or Article 6243g-4, Revised Statutes, or a successor statute to either of those laws, if the member:
(1)  was a member of the pension system as authorized under Section 16B, Chapter 358, Acts of the 48th Legislature, Regular Session, 1943 (Article 6243g, Vernon's Texas Civil Statutes);
(2)  is in a position covered by another retirement system to which the city contributes; and
(3)  has not begun to receive payment of benefits from the pension system.
(b)  A person who does not make an election to cease membership in the pension system under Subsection (a) of this section remains a member of the pension system as authorized under this Act.
(c)  A person who makes an election to cease membership in the pension system is considered to have separated from service on the date of the election established by the pension board.
(d)  Notwithstanding any other provision of this Act, duplication of any pension or benefit payable from the pension system and any pension or benefit payable under another defined benefit pension plan to which the city contributes is not permitted.  Any pension or benefit payable to any person under another defined benefit pension plan, based on a period of service for which credited service is given under this Act, is deducted from the total pension or benefit otherwise payable to the participant under this Act, except that the pension or benefit may not be reduced to an amount less than the amount that would have been payable if the period of service had been excluded from service.
Sec. 20.  SERVICE FOR FORMERLY INELIGIBLE EMPLOYEES.  (a)  A member who was ineligible to be a member under Section 4(d), Chapter 358, Acts of the 48th Legislature, Regular Session, 1943 (Article 6243g, Vernon's Texas Civil Statutes), before September 1, 1999, because the member was receiving a pension from another pension system of the city to which the city contributes may purchase credited service solely in group A for otherwise eligible service previously disallowed by Section 4(d), Chapter 358, Acts of the 48th Legislature, Regular Session, 1943 (Article 6243g, Vernon's Texas Civil Statutes), if the member:
(1)  has been continuously employed by the city since the date of reemployment into a municipal position that became covered by Chapter 358, Acts of the 48th Legislature, Regular Session, 1943 (Article 6243g, Vernon's Texas Civil Statutes), on September 1, 1999, by removal of the prohibition under Section 4(d), Chapter 358, Acts of the 48th Legislature, Regular Session, 1943 (Article 6243g, Vernon's Texas Civil Statutes);
(2)  would have been eligible to be a member and receive service for the municipal employment before September 1, 1999, but for the prohibition under Section 4(d), Chapter 358, Acts of the 48th Legislature, Regular Session, 1943 (Article 6243g, Vernon's Texas Civil Statutes);
(3)  was a member in group A on September 1, 1999, and on September 1, 2001;
(4)  makes written application, in a manner and time determined by the pension board, to receive credited service in group A for all otherwise eligible service; and
(5)  on approval by the pension board, pays into the pension fund all contributions that would have been deducted or picked up as member contributions during the period of claimed service as described by Section 7(c) of this Act, including required interest.
(b)  Payments of the amounts required under this section must be completed by the earliest of:
(1)  the date of the member's termination of employment or term in office;
(2)  the date of the member's retirement or death; or
(3)  the fifth anniversary of the date of the member's approved claim for credited service under this section.
(c)  If the payments are not completed within the period described by Subsection (b) of this section, the member or the member's estate may either make an immediate payment of the balance due or receive a refund, without interest, of the member's contributions to group A for the claimed service.  If the refund is paid, the member is considered to have never been eligible for credit for the service claimed under this section.
Sec. 21.  REDUCTION OF BENEFITS; DISSOLUTION OF SYSTEM.  (a)  If the pension board determines that the pension fund is seriously depleted, the pension board may proportionately and temporarily reduce the benefits of all retirees, eligible survivors, alternate payees, and beneficiaries.
(b)  The amount of any reduction under Subsection (a) of this section shall be paid to the retirees, eligible survivors, alternate payees, and beneficiaries if the pension board determines that the pension fund is sufficiently reestablished to pay the amounts.
(c)  If the reserve and surplus in the pension fund become exhausted and the payouts of the pension fund exceed the income to the pension fund, the governing body of the city by ordinance may dissolve the pension system and require liquidation of the pension system without any liability to the city.
(d)  Any retiree or eligible survivor receiving a retirement pension or survivor benefit may, at that person's option, receive a smaller retirement pension or survivor benefit after properly making a request in writing to the pension board.
Sec. 22.  EXEMPTION FROM EXECUTION, ATTACHMENT, OR OTHER WRIT.  (a)  No portion of the pension fund, either before or after its order of disbursement by the pension board, and no amount due or to become due to any retiree, eligible survivor, or beneficiary, may be held, seized, taken, detained, or levied on by, or subjected to, execution, attachment, garnishment, injunction, or any other writ.  No order or decree, or any process or proceeding, may be issued by a court of this state for the payment or satisfaction in whole or in part out of the pension fund of a debt, damage, claim, demand, or judgment against any member, retiree, eligible survivor, or other person.  The pension fund and any claim on the pension fund may not be directly or indirectly assigned or transferred.  Any attempt to transfer or assign the pension fund or any part of the pension fund, and any claim on the pension fund, is void.  The pension fund shall be sacredly held, kept, and disbursed only for the purposes provided by this Act, except that a retiree or eligible survivor may have deducted from that person's pension or survivor benefit an amount required by law or a voluntary amount authorized by law and the pension board.
(b)  This section does not prevent the division of benefits accrued by a member under any court order determined by the pension board or its designee to be a qualified domestic relations order and the payment of a share of a retiree's benefits or contributions to an alternate payee in accordance with the order.
(c)  This section does not prevent the offset of amounts received wrongly or in error against future pension or benefit payments under Section 3(h) of this Act.
Sec. 23.  FEDERAL TAX QUALIFICATION OF PENSION FUND; MAXIMUM BENEFITS FROM PENSION FUND.  (a)  The pension fund is intended to qualify under Section 401(a), Internal Revenue Code of 1986, as amended, and is for the exclusive benefit of the members and retirees and their eligible survivors.  No part of the corpus or income of the pension fund may ever be used for or diverted to any purpose other than for the benefit of members and retirees and their eligible survivors as provided by this Act.
(b)  A member, retiree, or eligible survivor of the pension system may not accrue a retirement pension, disability retirement allowance, survivor benefit, death benefit allowance, DROP benefit, or any other benefit under this Act in excess of the benefit limits applicable to the pension fund under Section 415, Internal Revenue Code of 1986, as amended.  The pension board shall reduce the amount of any benefit that exceeds those limits by the amount of the excess.  If total benefits under the pension fund and the benefits and contributions to which any member is eligible under any other qualified plan maintained by the city that employs the member would otherwise exceed the applicable limits under Section 415, Internal Revenue Code of 1986, as amended, the benefits the member would otherwise receive from the pension fund shall be reduced to the extent necessary so that the benefits do not exceed the benefit limits under Section 415, Internal Revenue Code of 1986, as amended.
(c)  Any member, retiree, or eligible survivor who receives any distribution that is an eligible rollover distribution as defined by Section 402(c)(4), Internal Revenue Code of 1986, as amended, is eligible to have that distribution transferred directly to another eligible retirement plan of the member's, retiree's, or eligible survivor's choice on providing direction to the pension system regarding that transfer in accordance with procedures established by the pension board.
(d)  The total salary taken into account for any purpose for any member or retiree of the pension system may not exceed $200,000 for any year for an eligible participant, or $150,000 a year for an ineligible participant.  These dollar limits shall be adjusted from time to time in accordance with guidelines provided by the United States secretary of the treasury.  For purposes of this subsection, an eligible participant is a person who first became a member of the predecessor system before 1996, and an ineligible participant is a member who is not an eligible participant.
(e)  Accrued benefits under this Act become 100 percent nonforfeitable for a member on the date the member has completed five years of credited service, except as otherwise provided by law.  If the pension system or the pension fund is terminated or partially terminated, or city contributions to the pension fund are discontinued completely, there may not be a reversion of funds to the city.  On the complete or partial termination or discontinuance of city contributions, the pension fund held by the pension system shall be used exclusively for benefits for members, deferred participants, retirees, and their eligible survivors, and the affected employees' rights to the benefits, to the extent funded, shall be nonforfeitable if not already nonforfeitable under this subsection.
(f)  Amounts representing forfeited benefits of terminated members may not be used to increase benefits payable from the pension fund, but may be used to reduce contributions for future plan years.
(g)  Distributions of benefits must begin not later than April 1 of the year following the calendar year during which the member becomes 70-1/2 years of age or terminates employment with the employer, if later, and must otherwise conform to Section 401(a)(9), Internal Revenue Code of 1986, as amended.
(h)  If the amount of any benefit is to be determined on the basis of actuarial assumptions that are not otherwise specifically set forth for that purpose in this Act, the actuarial assumptions to be used are those earnings and mortality assumptions being used on the date of the determination by the pension fund's actuary and approved by the pension board.  The actuarial assumptions being used at any particular time shall be attached as an addendum to a copy of this Act and treated for all purposes as a part of the Act.  The actuarial assumptions may be changed by the pension fund's actuary at any time if approved by the pension board.  A change in actuarial assumptions may not result in any decrease in benefits accrued as of the effective date of the change.
(i)  To the extent permitted by law, the pension board may adjust the benefits of retirees and eligible survivors by increasing any benefit that was reduced because of Section 415, Internal Revenue Code of 1986, as amended.  If Section 415, Internal Revenue Code of 1986, as amended, is amended to permit the payment of amounts previously precluded under that section, the pension board may adjust the benefits of retirees and eligible survivors, including restoring benefits previously denied.  Benefits paid under this subsection are not extra compensation earned after retirement but are the delayed payment of benefits earned before retirement.
(j)  The pension board may make any change in this Act to the extent that the change is necessary to ensure compliance with the qualification requirements of Section 401, Internal Revenue Code of 1986, as amended, or any other federal law.
Sec. 24.  EXCESS BENEFIT PLAN.  (a)  A separate, nonqualified, unfunded excess benefit plan is reenacted and continued outside the pension fund.
(b)  In this section:
(1)  "Excess benefit participant" means any retiree whose retirement benefits, as determined on the basis of all qualified plans without regard to the limitations provided by Section 23 of this Act and comparable provisions of other qualified plans, would exceed the maximum benefit permitted under Section 415, Internal Revenue Code of 1986, as amended.
(2)  "Excess benefit plan" means the separate, nonqualified, unfunded excess benefit plan that is continued under this section, that was created under the predecessor system for the benefit of eligible members, as amended or restated from time to time, and that is intended to be a qualified governmental excess benefit arrangement within the meaning of Section 415(m), Internal Revenue Code of 1986, as amended.
(3)  "Maximum benefit" means the retirement benefit a retiree and the surviving spouse or dependent child of a retiree or deceased member or retiree are eligible to receive from all qualified plans in any month after giving effect to Section 23 of this Act and any similar provision of any other qualified plan designed to conform to Section 415, Internal Revenue Code of 1986, as amended.
(4)  "Qualified plan" means the fund and any other plan that is maintained by the city for the exclusive benefit of some or all of the members of the fund and that has been found by the Internal Revenue Service to be qualified or has been treated by the city as a qualified plan under Section 401, Internal Revenue Code of 1986, as amended.
(5)  "Unrestricted benefit" means the monthly retirement benefit a retiree and the surviving spouse and dependent child of a retiree or deceased member or retiree would have received under the terms of all qualified plans, except for the limitations provided by Section 23 of this Act and any similar provision of any other qualified plan designed to conform to Section 415, Internal Revenue Code of 1986, as amended.
(c)  An excess benefit participant who is receiving benefits from the pension fund is eligible for a monthly benefit under the excess benefit plan in an amount equal to the lesser of:
(1)  the member's unrestricted benefit less the maximum benefit; or
(2)  the amount by which the member's monthly benefit from the pension fund has been reduced because of the limitations provided by Section 415, Internal Revenue Code of 1986, as amended.
(d)  If a surviving spouse or dependent child is eligible for preretirement or postretirement survivor benefits under a qualified plan after the date of the death of an excess benefit participant, the surviving spouse or dependent child is eligible for a monthly benefit under the excess benefit plan equal to the benefit determined in accordance with this Act, without regard to the limitations provided by Section 23 of this Act or Section 415, Internal Revenue Code of 1986, as amended, less the maximum benefit.
(e)  Any benefit to which a person is eligible under this section shall be paid at the same time and in the same manner as the benefit that would have been paid from the pension fund if payment of the benefit from the pension fund had not been precluded by Section 23 of this Act.  An excess benefit participant or a beneficiary of the participant may not, under any circumstances, elect to defer receipt of all or any part of a payment due under this section.
(f)  The pension board shall administer the excess benefit plan, and the executive director shall carry out the business of the board with respect to the plan.  Except as otherwise provided by this section, the rights, duties, and responsibilities of the pension board and the executive director are the same for the plan as for the pension fund.
(g)  The consultants, independent auditors, attorneys, and actuaries selected to perform services for the pension fund shall perform services for the excess benefit plan, but their fees for services may not be paid by the pension fund.  The actuary engaged to perform services for the pension fund shall advise the pension board of the amount of benefits that may not be provided from the pension fund solely by reason of the limitations provided by Section 415, Internal Revenue Code of 1986, as amended, and of the amount of employer contributions that will be made to the plan rather than to the pension fund.
(h)  Contributions may not accumulate under the excess benefit plan to pay future retirement benefits.  The executive director shall reduce each payment of employer contributions that would otherwise be made to the pension fund under Section 8A of this Act by the amount determined to be necessary to meet the requirements for retirement benefits under the plan, including reasonable administrative expenses, until the next payment of municipal contributions is expected to be made to the pension fund.  The employer shall pay to the plan, from the withheld contributions, not earlier than the 30th day before the date each distribution of monthly retirement benefits is required to be made from the plan, the amount necessary to satisfy the obligation to pay monthly retirement benefits from the plan.  The executive director shall satisfy the obligation of the plan to pay retirement benefits from the employer contributions transferred for that month.
(i)  Employer contributions otherwise required to be made to the pension fund under Section 8A of this Act and to any other qualified plan shall be divided into those contributions required to pay retirement benefits under this section and those contributions paid into and accumulated to pay the maximum benefits required under the qualified plan.  Employer contributions made to provide retirement benefits under this section may not be commingled with the money of the pension fund or any other qualified plan.
(j)  Benefits under this section are exempt from execution, attachment, garnishment, assignment, injunction, and any other writ in the same manner as retirement annuities under Section 22 of this Act and may not be paid to a person other than to the person who would have received the benefits from the pension fund except for the limitations provided by Section 23 of this Act.
Sec. 25.  EMPLOYEES ON RETIREMENT WHEN ACT TAKES EFFECT.  (a)  Any person receiving a retirement benefit from the predecessor system immediately before the effective date of this Act shall continue to receive the same benefit amount the person was entitled to receive under the predecessor system.
(b)  This Act does not change the status of any former member receiving a pension, or who is eligible to receive a pension, from the city or the pension system under the predecessor system, unless otherwise expressly provided by this Act.
Sec. 26.  CONFIDENTIAL INFORMATION.  (a)  Records that are in the custody of the pension system concerning an individual member, deferred participant, retiree, eligible survivor, beneficiary, or alternate payee are not public information under Chapter 552, Government Code, and may not be disclosed in a form identifiable to a specific individual unless:
(1)  the information is disclosed to:
(A)  the individual or the individual's attorney, guardian, executor, administrator, or conservator, or another person who the executive director determines is acting in the interest of the individual or the individual's estate;
(B)  a spouse or former spouse of the individual and the executive director determines that the information is relevant to the spouse's or former spouse's interest in a member's accounts or benefits or other amounts payable by the pension system;
(C)  a governmental official or employee and the executive director determines that disclosure of the information requested is reasonably necessary to the performance of the duties of the official or employee; or
(D)  a person authorized by the individual in writing to receive the information; or
(2)  the information is disclosed under a subpoena and the executive director determines that the individual will have a reasonable opportunity to contest the subpoena.
(b)  This section does not prevent the disclosure of the status or identity of an individual as a member, former member, deferred participant, retiree, deceased participant, eligible survivor, beneficiary, or alternate payee of the pension system.
(c)  The executive director may designate other employees of the pension system to make the necessary determinations under Subsection (a) of this section.
(d)  A determination and disclosure under Subsection (a) of this section does not require notice to the individual member, deferred participant, retiree, eligible survivor, beneficiary, or alternate payee.
Sec. 27.  POWER OF ATTORNEY.  (a)  A person eligible for payment of a pension or other benefits administered by the pension system may direct the pension system to treat as the authorized representative of the person concerning the disposition of the pension or other benefits an attorney-in-fact under a power of attorney that the pension system determines complies with Subchapters A and B, Chapter 752, Estates Code.
(b)  If the power of attorney under Subsection (a) of this section is revoked, the pension system is not liable for payments made to or actions taken at the request of the attorney-in-fact before the date the pension system receives written notice that the power of attorney has been revoked.
Sec. 28.  PROPORTIONATE RETIREMENT PROGRAM WITH PARTICIPATING RETIREMENT SYSTEMS.  (a)  The pension board may establish a program of proportionate retirement benefits subject to the requirements of this section.
(b)  In this section:
(1)  "Combined service credit" means the combined sum of an eligible participant's service credit in each participating retirement system in which the participant has service credit and for which the total satisfies the length-of-service requirements for normal service retirement from that system at the eligible participant's attained age.
(2)  "Eligible participant" means a person who is or has been a member of the pension system and who is actively employed by the city and covered by a participating retirement system at the time of full participation by the three retirement systems established by Article 6243e.2(1), Revised Statutes, Article 6243g-4, Revised Statutes, a successor statute to either of those laws, and this Act.  An eligible participant does not include any individual who:
(A)  is in retirement or DROP status;
(B)  is receiving a retirement pension; or
(C)  is in a probationary or trainee firefighter or police officer position.
(3)  "Full participation" means that a retirement system has met the requirements of a participating retirement system.
(4)  "Maximum benefit" means the maximum total amount of benefits payable to an eligible participant who has used combined service credit to qualify for benefits from a participating retirement system, which is 90 percent of the participant's average monthly compensation at the time the participant ceases employment in a position covered by the pension system.
(5)  "Participating retirement system" means a retirement system that is established by Article 6243e.2(1), Revised Statutes, Article 6243g-4, Revised Statutes, a successor statute to either of those laws, or this Act and that recognizes and allows the use of combined service credit and disability determinations to provide proportionate retirement benefits in its system for an eligible participant under the provisions of this Act.
(6)  "Service credit" means service that is credited by the rules of a participating retirement system and that may be used to meet length-of-service requirements for service retirement in the system, except that service credit that would otherwise be allowed by more than one participating retirement system for the same service period is counted only once in determining the amount of a person's combined service credit and applies as service credit only in the participating retirement system in which the person first established the service credit.
(c)  Participation by the pension system in the proportionate retirement program is voluntary.  The pension board may elect to participate in the proportionate retirement program by adopting a resolution.  If a resolution is adopted, the pension board shall notify the other participating retirement systems of the election.  The effective date of participation in the proportionate retirement program for which an election is made is the first day of the third month after the month in which notice is given.  Participation in the proportionate retirement program by the pension system may be terminated for any reason by adoption of a pension board resolution, except that the proportionate retirement program will be continued by the pension system for eligible participants who are actively employed at the time of the termination and who remain actively employed.  On adoption of a resolution of termination, the pension board shall notify the other participating retirement systems of the termination.  The effective date of termination from the proportionate retirement program is the first day of the month following the month in which notice of termination is given.
(d)  An eligible participant's combined service credit may be used only for determining eligibility for a normal retirement pension under this Act and may not be used in determining eligibility for DROP participation, a disability pension, survivor benefits, or any type of benefit other than a normal retirement pension, nor may combined service credit be used in determining the amount of any type of pension or benefit.  The amount of a pension or benefit payable by the pension system is determined according to, and in the manner prescribed by, this Act and the rules established by the pension board and is based solely on an eligible participant's service credit in the pension system and allowable maximum benefit.  The pension board has sole responsibility and discretion to determine the eligibility of eligible participants for benefits, including whether sufficient combined service credit exists to qualify eligible participants for proportionate retirement benefits from the pension system and the amount and duration of proportionate retirement benefits payable by the pension system.
(e)  A person who withdraws pension contributions from a participating retirement system ceases to be a member of that participating retirement system.  Membership and service credit for which contributions were withdrawn or otherwise forfeited may be reestablished under the statutes and rules governing that system.  To be counted as combined service credit, all service in a participating retirement system for which the person withdrew contributions or that was otherwise forfeited must be reinstated in accordance with the statutes and rules applicable to that system.  A lump-sum distribution is governed by the statutes and rules applicable to the particular retirement system that distributed the lump-sum payment.
(f)  A person who has service credit in another participating retirement system for which the person is receiving or may become eligible to receive a benefit is not eligible to vote in a pension board election or hold a position on the pension board.
(g)  The pension board shall make determinations regarding an eligible participant's combined service credit based on the certified records of a participating retirement system, including the pension system, and of the city.
(h)  The provisions of Section 17 of this Act relating to termination of employment do not apply to an eligible participant to the extent the participant is separated from service covered by the pension system during a period for which the participant earns service credit in another participating retirement system for service performed for the city in an amount sufficient to meet the length-of-service requirement, using combined service credit, for a retirement benefit from the participating retirement system.
(i)  A proportionate retirement benefit may be paid by the pension system under the proportionate retirement program to an eligible participant who fulfills the requirements for receiving a proportionate retirement benefit in the pension system using combined service credit only if the participant is eligible to receive and has applied for proportionate retirement benefits from the applicable other participating retirement systems.  An eligible participant may not become eligible to receive a proportionate retirement benefit from the pension system while employed in a position covered by the pension system.
(j)  The pension system is governed solely by its own statutory provisions, policies, and procedures relating to disability benefit determinations for members who apply for a disability pension from the pension system, except that the pension system shall pay a proportionate amount of the ordinary disability benefit attributable to the service credited under the pension system, based on the schedule of benefits in effect under this Act or Chapter 358, Acts of the 48th Legislature, Regular Session, 1943 (Article 6243g, Vernon's Texas Civil Statutes), as applicable, on the eligible participant's last day of credited service as a member in the pension system if:
(1)  the eligible participant has combined service credit from any other participating retirement system in addition to the pension system;
(2)  the eligible participant files for a disability pension for the first time as a member of the other participating retirement system;
(3)  the eligible participant is otherwise eligible for a disability pension in both participating retirement systems;
(4)  the eligible participant receives a determination from the pension board of trustees of the other participating pension system that the person has a disability that is of a type recognized by the pension system; and
(5)  the other participating retirement system grants the disability pension.
(k)  If the disability is determined to be service-related, the pension system shall pay only the ordinary disability benefit amount.  The pension board has the right to require examinations, reports, and any other information permitted under this Act for the administration and payment of disability benefits and the right to reduce, suspend, or terminate a benefit accordingly.  The benefit allowed under this subsection and Subsection (j) of this section is payable only if the other participating retirement systems authorize and pay a disability benefit under the same circumstances as provided by this subsection.  A person who is receiving a disability benefit from a participating retirement system is not eligible for a disability pension under this Act, except as provided by this subsection and Subsection (j) of this section.
(l)  Creditable military service, if any, will be credited in the pension system only as provided by this Act and only if the service is not credited in any other participating retirement system.
(m)  If the pension board elects to participate in the proportionate retirement program under this section, the pension board shall adopt rules for implementing and administering the proportionate retirement program.
(n)  A person may not receive a benefit under this section in an amount that is greater than the amount of the benefits accrued by the person in the absence of this section.  A survivor benefit otherwise payable under Section 14(c) of this Act on behalf of a person who has used combined service credit to qualify for benefits from at least one participating retirement system shall be computed and payable as provided by Section 14(b) of this Act.
