Which investment return metric accounts for the scale of cash flows and timing of investments?

• A. Time-zero based pooling
• B. Pooled IRR or IIRR
• C. Commitment-weighted IRR
• D. Exit timing

Answer: (B)

The pooled IRR (Internal Rate of Return) is designed to accurately reflect the performance of investments while taking into account both the scale of cash flows and the timing of these cash flows. This metric is particularly useful in situations where there are multiple investments or cash flows occurring at various times, such as in private equity and other alternative investments.

Pooled IRR calculates a single internal rate of return that represents the aggregate performance of the investments by considering when cash inflows and outflows occur. By pooling returns, it effectively weights cash flows based on their timing and size, allowing investors to assess the performance of their contributions over time.

In contexts where investment amounts vary significantly or where cash flows occur non-uniformly over time, pooled IRR provides a clear and coherent measure of investment performance that recognizes the impact of these factors. This makes it especially valuable for evaluating funds or portfolios where multiple cash flows are received or invested at different stages.

Other options might not incorporate the timing and scale aspects as effectively. For example, commitment-weighted IRR focuses more on the commitments made rather than the actual cash flows and their timing. Thus, while commitment-weighted IRR can be useful in certain scenarios, it does not fully encapsulate the essence of investment performance in
