CFA Level 3 IPS constraints and objectives writing
An investment policy statement connects return and risk objectives with liquidity, horizon, tax, legal and unique constraints. Write each statement from case facts and distinguish the investor’s willingness to accept risk from the ability to bear losses.
The key ideas, at a glance
Return objective
Read the visual, then follow the worked example below. Use the stated case assumptions.
Illustrative worked case
million
- Due in 3 months
- 0.1 (10%)
- Remaining assets
- 0.9 (90%)
The 1m portfolio must supply 100,000 within three months. The remaining assets can have separate objectives and constraints.
| Concept | Rule or decision | Common mistake |
|---|---|---|
| Return objective | Express the required return with the case’s nominal or real and pre-tax or after-tax convention. | Do not silently mix spending, inflation and investment return conventions. |
| Risk objective | Assess both risk willingness and financial capacity; resolve conflicts in the case. | High stated willingness does not create the ability to replace lost capital. |
| Liquidity and horizon | List dated cash needs and relevant investment stages. | A cash withdrawal next month is not a long-term growth objective. |
| Other constraints | State relevant tax treatment, legal restrictions and unique requirements explicitly. | Add only facts supported by the case; do not invent client restrictions. |
01Return objective
Express the required return with the case’s nominal or real and pre-tax or after-tax convention.
Watch for: Do not silently mix spending, inflation and investment return conventions.
02Risk objective
Assess both risk willingness and financial capacity; resolve conflicts in the case.
Watch for: High stated willingness does not create the ability to replace lost capital.
03Liquidity and horizon
List dated cash needs and relevant investment stages.
Watch for: A cash withdrawal next month is not a long-term growth objective.
04Other constraints
State relevant tax treatment, legal restrictions and unique requirements explicitly.
Watch for: Add only facts supported by the case; do not invent client restrictions.

Put the method to work
One worked example, from facts to answer
Given
A client has a 1 million investable portfolio and must withdraw 100,000 in three months. The prompt asks for a liquidity constraint.
Method
State the amount and timing: the portfolio must provide 100,000 of liquidity within three months.
Answer and interpretation
The constraint is a dated cash need. It does not mean the entire remaining portfolio has a three-month horizon.
Original independent teaching example. Assumptions are stated above; this is not an official exam question or scoring key.
Apply the framework, step by step
Write a return/risk objective or constraint from case facts without inventing client information. Use Portfolio Construction for the broader suitability and implementation process.
Before you start: Nominal versus real returns, pre-tax versus after-tax conventions, risk willingness versus capacity and dated cash needs.
METHOD 01
Return objective
Express the required return with the case’s nominal or real and pre-tax or after-tax convention.
Read the requested return convention before combining spending, inflation, fees or taxes. A nominal return includes inflation; a real return removes its effect. A simple percentage sum can be a stated approximation, while exact compounding uses the relevant multiplicative relationship. Label the convention and use only the inputs the case supplies. Do not promise that a calculated required return is achievable.
Avoid this mistake: Do not silently mix spending, inflation and investment return conventions.
METHOD 02
Risk objective
Assess both risk willingness and financial capacity; resolve conflicts in the case.
Assess willingness and ability to bear risk separately. A client may welcome volatility while depending on the portfolio for an unavoidable near-term payment. The financial capacity to recover from a loss constrains the recommendation even when stated willingness is high. When the two conflict, explain the conflict and the response rather than averaging vague low/high risk labels.
Avoid this mistake: High stated willingness does not create the ability to replace lost capital.
METHOD 03
Liquidity and horizon
List dated cash needs and relevant investment stages.
A liquidity constraint should name the amount, date and any relevant reliability of offsetting inflows. A time horizon can have several stages and is not automatically equal to the next withdrawal date. Separating the cash need from the long-term objective avoids placing the entire portfolio into a strategy built for one near-term obligation.
Avoid this mistake: A cash withdrawal next month is not a long-term growth objective.
METHOD 04
Other constraints
State relevant tax treatment, legal restrictions and unique requirements explicitly.
Use only tax, legal, regulatory and unique requirements supported by the case. Constraints can exclude an asset, limit concentration or affect the account structure and implementation. Do not invent a tax rate, estate instrument or prohibition because it seems typical for the investor. Write the objective or constraint in a concise sentence that another portfolio manager could actually use.
Avoid this mistake: Add only facts supported by the case; do not invent client restrictions.
Apply it to a different case
- New facts
- A client requires a 3% real return. Expected inflation is 2%. Ignore taxes and fees and use exact compounding.
- Working
- Required nominal return = (1.03 × 1.02) - 1 = 0.0506.
- Conclusion
- The corresponding nominal requirement is 5.06% under those assumptions. It is a required-return calculation, not a promised portfolio outcome.
Original teaching case under the stated assumptions, rather than an official exam question.
Questions about this method
- Are willingness and ability to take risk the same?
- No. Willingness describes a preference or attitude toward uncertainty. Ability reflects financial capacity and obligations. A recommendation must consider both, including conflicts between them.
- Does a withdrawal date define the whole investment horizon?
- Not necessarily. The withdrawal creates a dated liquidity need, while the remaining assets can support a separate longer-term objective. Use the case’s stages and obligations.
- Should I add typical client constraints that the case omits?
- No. State the constraints supported by the facts. Invented tax, legal or personal restrictions can change the recommendation and make it answer a different case.
