Stony Brook and Northwell employees: coordinating NYSTRS with your 403(b).

The defining planning question for most Long Island hospital-system employees is not 'how should I invest my 403(b)?' It is 'how do my pension, my 403(b), and — sometimes — my spouse's benefits actually work together in retirement?' The hospital systems Long Island households work at are built on a mix of public-pension, private-pension-equivalent, and 403(b) mechanics that interact in ways the generic retirement planning literature does not capture.

This note walks through the coordination problem the way Camba walks through it at the kitchen table — which pension applies at which system, how the 403(b) supports (or doesn't support) the pension, and what the rollover decision actually looks like at retirement.

1. First: which pension are you actually in?

The three dominant Long Island hospital systems have genuinely different retirement architectures, and employees are routinely unclear about which plan they are actually enrolled in.

• Stony Brook University and Stony Brook Medicine. As part of SUNY and the State of New York, Stony Brook employees are generally enrolled in either NYSTRS (academic faculty) or NYSLRS (most non-academic staff), with an Optional Retirement Program (ORP) alternative for many faculty that replaces the NYSTRS pension with a TIAA-administered defined-contribution benefit. Which system applies depends on job category and, for ORP-eligible staff, on an enrollment decision made early in the career.
• Northwell Health. A private-sector health system. Employees are covered under Northwell's own retirement plans, which have evolved across corporate reorganizations. Many long-tenured Northwell employees have a frozen legacy defined-benefit or cash-balance plan from before a plan change, alongside a current 403(b). Newer employees generally have only the 403(b) plus an employer match.
• NYU Langone Health. A private, non-profit academic medical center. Employees are covered under NYU's retirement plans, which are almost entirely 403(b)-based with employer contributions. There is generally no defined-benefit pension to elect. Senior physicians and executives may have supplemental non-qualified deferred compensation plans.

The practical move: pull the Summary Plan Description for every retirement plan the employee is enrolled in (or has been enrolled in at a previous employer), and confirm in writing what benefits are actually payable. For Stony Brook in particular, the ORP-versus-NYSTRS decision made at hire reshapes everything about retirement, and many employees do not remember which path they chose.

2. The pension floor changes the 403(b) allocation question.

For an employee with a meaningful defined-benefit or defined-benefit-equivalent pension — a NYSTRS faculty member, a Tier 4 NYSLRS staff member, or a long-tenured Northwell employee with a frozen cash-balance plan — the pension acts as a bond-like income floor in retirement. Twenty or thirty years of guaranteed monthly income from NYSTRS is, in portfolio terms, equivalent to a very large allocation to fixed income.

That changes the 403(b) allocation question. A generic age-based glide-path suggests a 60-year-old hospital employee should hold 40–50% bonds inside the 403(b). For an employee whose pension already provides the household's income floor, that same 403(b) can rationally be tilted more heavily toward equities — not because the household has higher risk tolerance, but because the overall household balance sheet (pension value plus 403(b)) already has the bond-like exposure it needs. Treating the pension as zero when sizing the 403(b) allocation is a common error. It leaves the household meaningfully under-invested.

For employees without a real pension — most Northwell employees under current plans, most NYU Langone employees — the 403(b) has to do the entire retirement-income job. The allocation question is then straightforward age-based, because no pension floor exists to offset.

3. The TIAA traditional question.

Both Stony Brook ORP participants and many hospital-system 403(b)s include TIAA Traditional as an investment option. TIAA Traditional is not a traditional bond fund. It is a guaranteed-minimum-rate accumulation contract with a crediting-rate history that has been generally competitive with intermediate-duration bonds and with substantially less volatility. Some vintages of TIAA Traditional carry liquidity restrictions — they can only be withdrawn over a nine-to-ten-year Transfer Payout Annuity schedule rather than as a lump sum.

The planning implication: TIAA Traditional balances are often worth keeping in place at retirement rather than rolling into an IRA. The crediting rate is genuinely competitive, and the accumulation contract is not replicable outside the TIAA plan. A retail bond fund at a custodian does not match the TIAA Traditional crediting history.

This is the single most common place hospital-system employees overlook in the rollover conversation. A generic 'roll the 403(b) into a rollover IRA' decision can leave meaningful income on the table if TIAA Traditional is a large piece of the balance.

4. The rollover decision at retirement.

A hospital-system employee retiring with a pension plus a 403(b) has four practical paths for the 403(b) balance. The right choice depends on what is actually inside the 403(b) and what the household's planning horizon looks like.

• Leave it in place. Best for employees with meaningful TIAA Traditional balances, strong institutional share-class index fund access inside the 403(b), and a real creditor-protection need.
• Partial rollover. Roll the non-TIAA-Traditional portion of the balance to an IRA for Roth conversion flexibility and investment-menu breadth, while leaving the TIAA Traditional allocation in place inside the 403(b). This is frequently the right answer for Stony Brook ORP participants and long-tenured Northwell employees.
• Full rollover to an IRA. Best for employees whose 403(b) is high-cost, whose investment menu is thin, and who do not have a TIAA Traditional position worth preserving. Also the path that provides the cleanest Roth conversion mechanics in the low-income years between retirement and RMDs.
• Annuitize a portion. Some hospital 403(b)s — especially TIAA-administered plans — allow a portion of the balance to be converted into a lifetime annuity at retirement. For households whose pension is small relative to their spending needs, layering on additional lifetime income can be rational. For households whose pension already provides a large income floor, this is usually unnecessary.

5. Roth conversion space in the low-income years.

For a hospital-system employee retiring in their early sixties with a pension that starts immediately, the household's taxable income in the retirement years is substantially determined by the pension. The Roth conversion space — the room to convert traditional 403(b) or IRA balances to Roth at low marginal tax rates — is therefore smaller than it is for a retiree without a pension, but it is not zero, and the math still works.

The years between retirement and age 73 (or 75, depending on birth year) when Required Minimum Distributions begin are the cheapest tax brackets the household will ever inhabit, because Social Security can be delayed to 70 to increase the eventual benefit. Even with a NYSTRS or NYSLRS pension filling the 22% bracket, there is typically some additional Roth conversion space in the 22% or 24% bracket that is worth using — converting a portion of the 403(b) or IRA to Roth each year — rather than letting those dollars compound into forced RMDs and higher-bracket withdrawals later.

Done well, ten years of measured Roth conversions can move $300,000 to $500,000 from pre-tax to Roth at marginal rates of 22% to 24%, versus the 24% to 32% rates those same dollars would otherwise face when RMDs begin and when a surviving spouse eventually files as single. Done poorly — or not at all — those dollars compound quietly into a larger forced-distribution problem.

6. The decision-day checklist for hospital-system employees.

• Confirm which pension or pension-equivalent plan actually applies. For Stony Brook employees, confirm NYSTRS versus NYSLRS versus ORP enrollment. For Northwell employees, confirm whether a frozen DB or cash-balance plan is in the picture alongside the 403(b).
• Pull the 403(b) statement and identify the TIAA Traditional allocation, if any. Separate TIAA Traditional from the rest of the balance in the planning analysis.
• Model the household's retirement income under the pension election plus a range of 403(b) drawdown strategies. Include Social Security claiming at multiple ages for both spouses.
• Identify the Roth conversion space in the low-income years between retirement and RMD age. Plan annual conversion amounts to stay within a target marginal tax bracket.
• Decide on a 403(b) handling plan — leave in place, partial rollover, full rollover, or annuitize — before the retirement date is locked in. Rollovers and annuitizations are much cleaner to execute at separation from service than years later.

The hospital-system retirement picture is a coordination problem, not an investment problem. The 403(b) allocation only makes sense in the context of the pension. The rollover decision only makes sense in the context of what is inside the 403(b). And the Roth conversion opportunity only makes sense in the context of the household's entire twenty-year tax trajectory.
