62.622(2)(b)(b) An entity described under par. (a) has all of the powers provided to it under applicable law and the documents pursuant to which it is created and established.

62.622(3)(a)(a) To facilitate a pension funding plan a common council may establish a stabilization fund. Any such fund may be created as a trust, a special fund or account of the city established by a separate resolution or ordinance, or a fund or account created under an authorizing resolution or trust indenture in connection with the authorization and issuance of appropriation bonds under s. 62.62 or general obligation promissory notes under s. 67.12 (12). A city may appropriate funds for deposit to a stabilization fund established under this subsection.

62.622(3)(b)(b) Moneys in a stabilization fund established under this subsection may be used, subject to annual appropriation by the common council, solely to pay principal or interest on appropriation bonds issued under s. 62.62 and general obligation promissory notes under s. 67.12 (12) issued in connection with a pension funding plan, for the redemption or repurchase of such appropriation bonds or general obligation promissory notes, to make payments under any agreement or ancillary arrangement entered into under s. 62.621 with respect to such appropriation bonds or general obligation promissory notes, or to pay annual pension costs other than normal costs. Moneys on deposit in a stabilization fund may not be subject to any claims, demands, or actions by, or transfers or assignments to, any creditor of the city, any beneficiary of the city’s employee retirement system, or any other person, on terms other than as may be established in the resolution or ordinance creating the stabilization fund. Moneys on deposit in a stabilization fund established under this subsection may be invested and reinvested in the manner directed by the common council or pursuant to delegation by the common council as provided under s. 66.0603 (5).

IV of ch. 111 and except as provided in subs. (2) and (3) employees shall pay all employee required contributions for funding benefits under the retirement system.

62.623 AnnotationThis section concerns a matter of primarily statewide concern and, accordingly, survives the plaintiffs’ home rule challenge under article XI, section 3 (1), of the Wisconsin Constitution. Madison Teachers, Inc. v. Walker, 2014 WI 99, 358 Wis. 2d 1, 851 N.W.2d 337, 12-2067.

62.623 AnnotationThis section does not violate the contract clause, article I, section 12, of the Wisconsin Constitution. Nothing in 2011 Wis. Act 10 purports to reduce, impair, or affect in any way benefits that have already accrued to plan members. This section modifies only the method by which the Milwaukee Employes’ Retirement System is funded; the pension, disability, and death benefits that accrue to plan members pursuant to the terms and conditions in the Milwaukee retirement system ordinance remain unaffected. Madison Teachers, Inc. v. Walker, 2014 WI 99, 358 Wis. 2d 1, 851 N.W.2d 337, 12-2067.

62.624(1)(a)(a) The mental injury resulted from a situation of greater dimensions than the day-to-day mental stresses and tensions and post-traumatic stress that all similarly situated employees must experience as part of the employment.

62.624(1)(b)(b) The employer certifies that the mental injury is a duty-related injury.

62.624(2)(2) If an employee retirement system of a 1st class city determines that an applicant is not eligible for duty disability benefits for a mental injury, the applicant may appeal the employee retirement system’s determination to the department of workforce development. In hearing an appeal under this subsection, the department of workforce development shall follow the procedures under ss. 102.16 to 102.26.

62.62562.625 Amortization period for employer contributions. Notwithstanding any provision of law or actuarial rule, beginning in the calendar quarter of the year that a tax is first imposed under s. 77.701 (1), in any retirement system of a 1st class city, the required annual employer contribution shall be calculated using a 30-year amortization period and an annual investment return assumption that is the same as or less than the annual investment return assumption used by the Wisconsin Retirement System for participating employees, as defined in s. 40.02 (46). Future unfunded actuarial accrued liability due to factors such as market returns and standard actuarial practices may be amortized on the basis of standard actuarial practices. The amortization period and investment return assumptions in this section shall supersede any amortization period and investment return assumption adopted by the actuary or retirement board of the retirement system of the city. No trustee or administrator of a retirement system of a 1st class city shall be subject to liability for complying with this section.
