The six sections of an IPS
| Section | What it specifies | Where the data comes from |
|---|---|---|
| Return objectives | Required real return to fund stated goals (e.g., retirement income, education funding, charitable giving); usually expressed as a target nominal return + an inflation assumption | KYC: stated objectives + time horizon + required spending |
| Risk tolerance | Emotional capacity to stomach drawdowns (typically stated as a maximum acceptable peak-to-trough drawdown or a quantitative volatility budget) | KYC: drawdown counterfactual responses, prior behavior in selloffs |
| Liquidity needs | Minimum cash / cash-equivalent reserve to cover short-term spending and emergencies (typically 0-3 year requirements) | KYC: spending pattern, emergency-fund philosophy, upcoming known cash outflows |
| Time horizon | When the money is needed -- single horizon (goal-based) or multi-stage (e.g., accumulation, decumulation phases) | KYC: age, retirement date, dependent education, intergenerational planning |
| Tax + legal constraints | Tax bracket, asset-location preferences (tax-deferred vs taxable accounts), prohibited investments (e.g., trust restrictions, ESG mandates, employer-stock restrictions for executives), state-specific rules | KYC: tax situation, account types, employer rules, trust documents |
| Unique circumstances | Anything that does not fit the previous five sections -- concentrated holdings, business ownership, family obligations, philanthropic intent, behavioral biases the advisor and client have agreed to manage around | KYC: other assets, source of funds, family situation |
Why the rebalancing clause is the most under-used section
The most under-used IPS section is the REBALANCING POLICY clause -- the rule for when and how to restore target weights. A good rebalancing clause has three components. (1) A trigger -- either time-based (rebalance every quarter / every year), threshold-based (rebalance when any asset class drifts more than X percentage points or Y percent of its target weight), or hybrid (annual rebalance plus interim threshold trigger). Threshold-based is operationally more efficient because it skips rebalances when nothing has drifted; time-based is simpler to communicate. (2) A tolerance band -- how big the deviation must be before the trigger fires (5 percentage points is a common default for major asset classes; 25% of target weight is the common percent-based equivalent). (3) A tax-awareness clause -- prefer rebalancing with new contributions and dividend reinvestment first (zero-cost), use tax-loss harvesting opportunities, and only sell taxable winners when the threshold demands it. The clause is short -- 4-6 sentences -- but doing without it leaves rebalancing to discretion, and discretion is exactly what the IPS exists to override.
The required nominal return formula
Required nominal return = ((1 + required_real_return) * (1 + inflation)) - 1
Turning a spending need into a required return
The defaults above ($80K spending / $2M portfolio / 2.5% inflation) produce a 4.00% required REAL return — the same number as, but NOT the same plan as, the famous '4% rule'. Real return required = 80,000 / 2,000,000 = 4.00%. Nominal return required = ((1.04 * 1.025) - 1) = 6.60%. This is the calculation that anchors the IPS return-objectives section -- before any discussion of equity-vs-bond weights, the required nominal return tells you what the portfolio must earn to fund the plan. Drag spending up to $120K and watch the verdict shift to STRESSED: real return required becomes 6.00%, nominal 8.65%, which is well above what a 60/40 portfolio has historically earned -- meaning the IPS must surface this gap to the client and force a trade-off conversation (lower spending, work longer, accept higher risk of plan failure, or shift to higher equity allocation with larger drawdown risk). The math is the prompt for the conversation. Do not conflate the two: the 4% safe-withdrawal-rate research (Bengen, Trinity study) assumes the retiree spends PRINCIPAL down over a roughly 30-year horizon, while this IPS calculation demands the portfolio fund spending as a PERPETUITY that never touches principal. The perpetuity target is materially more conservative -- confusing the two overstates what a portfolio sized to the 4% rule can support forever.

When a funded goal should revise the IPS
Why a smaller goal means less required risk
The disciplined revision lowers the required return. The IPS is revised on LIFE EVENTS, and a tuition-discount that materially reduces the goal IS a life event -- it changes the actual required outcome. With lower required return, the portfolio can take less risk, which means lower expected drawdowns and a higher probability the goal is funded even in a bad market sequence. The 'no revision' answer is rigid in the wrong direction: the IPS is supposed to track actual circumstances, not be ignored when they change. The 'revise upward to other goals' answer treats the freed capital as opportunity to chase higher returns, which would be appropriate only if the client has a separate documented goal with its own IPS. The 'liquidate early' answer locks in a position but skips the revision conversation that is the actual point. Revising an IPS on a real life event is good practice; revising on market moves is bad practice -- the distinction is exactly the IPS's reason for existing.
Two reasons to write an IPS for yourself

Four IPS failure modes to watch for
Going deeper (optional). Up next: four IPS failure modes to watch for, whether your adviser drafts it or you do — an advanced aside you can skip on first pass and come back to anytime. Continue when you're curious.
Going Deeper -- four IPS failure modes to watch for, whether your adviser drafts it or you do. (1) Written and never re-read: the IPS gets signed at account opening and lives in a drawer; it is never referenced during reviews; it has zero behavioral protection value. Fix: re-read it at every review, even for 60 seconds. (2) Missing rebalancing clause: the policy says nothing about when to rebalance, so rebalancing becomes ad-hoc discretion and the portfolio quietly drifts. Fix: insist the clause exists -- trigger + tolerance + tax-awareness. (3) Returns-revised, not life-revised: the IPS gets updated chasing recent performance instead of in response to actual life events; the document becomes a lagging indicator of bias instead of a leading indicator of commitment. Fix: separate revision triggers ('life event' vs 'preference change') and require the second category to come with a written reason. (4) Cross-link with the portfolio modules: the corpval and portfolio paths (port-3, port-4 if present) cover the asset-allocation math the IPS commits to; the IPS is the policy, the asset-allocation work is the implementation -- two sides of one job. An AI prompt you can use to draft or stress-test your own: 'Given this KYC summary, draft a one-page IPS covering all six RR-LTLU sections plus a rebalancing-policy clause, in 250 words or fewer.' The next module turns from the document to the end-to-end onboarding workflow that puts everything above into motion.
Sit with the ideas.
A client's IPS specifies a 60% equity / 40% fixed-income target allocation, with a 'rebalance when any asset class drifts more than 5 percentage points from target' rule. After a strong equity year the portfolio is 70% equity / 30% fixed income. The client says they are reluctant to sell winners and would rather wait for fixed income to catch up. Under the disciplined IPS framework, what should the advisor do?
