The state Legislature and Comptroller Tom DiNapoli should reject Gov. Andrew Cuomo’s proposal to lock in local in pension costs at the expense of future savings, Syracuse mayor and Democratic Party Co-Chairwoman Stephanie Miner wrote in a New York Times op/ed posted this evening.

The development comes after Miner expressed skepticism over the proposal ever since Cuomo announced the plan as a mandate relief provision in his $142.6 billion budget due April 1.

Though Cuomo has stressed that the pension smoothing plan is voluntary, it is highly unusual that the governor’s hand-picked political leader would not only publicly rebuke him, but call on lawmakers and a statewide elected official to do the same.

In the op/ed, Miner says the proposal “amounts to an accounting gimmick” that could lead to “a path to insolvency.”

From the piece:

Mr. Cuomo’s budget proposal would let municipalities and school districts address rising pension costs by borrowing more now — which will mean paying more later on, as interest rates, now at historic lows, are sure to rise. Pension payments have skyrocketed since the stock market plunged in 2007-8; though the market has rebounded, the financial projections underlying pension calculations have changed and the wave of boomer retirees is continuing to drive up costs. Borrowing makes sense when you’re building schools or roads; using it to pay for recurring costs like retiree benefits is a path to insolvency.

Miner insists that she remains an ally of the governor.

But the op/ed’s scathing portrayal of Cuomo’s pension stabilization proposal calls into question how long she will remain in her position as a party leader.

In Albany to testify on the budget proposal, Miner said her political duties and job as mayor of an upstate city with troubled finances do not conflict. Cuomo has said very much the same on whether she will remain co-chairwoman.

Other large-city mayors in the state support the measure, including Rochester’s Tom Richards, who told reporters the same day that the pension smoothing plan will help him meet budgetary needs in the coming fiscal year.
