Financial Highlights under US GAAP – Total Return Vs Internal Rate of Return

Author: DM Technical Team : April 2026

In financial reporting and investment analysis, measuring performance is essential to provide users of the financial statements with useful, transparent information. Two commonly used performance metrics are Total Return and Internal Rate of Return (“IRR”).

Both metrics can help assess investment results but they serve different purposes and can yield significantly different insights. For accounting professionals working under US GAAP, understanding these differences is key to ensuring accurate reporting and clear disclosures are effectively communicated to users of the financial statements and the various stakeholders.

In this article the DM Technical Team explore the critical considerations when assessing which performance metric should be applied to investment companies under ASC 946 i.e. Total Return presentation or Internal Rate of Return presentation if they meet the specific criteria under ASC 946-205-50-23.

Key characteristics of Total Return

Total Return measures the overall gain or loss on an investment over a specified period, expressed as a percentage of the initial investment. It is widely used in fund reporting, particularly for mutual funds and public market investments as it is easy to calculate and communicate. It provides investors with a straightforward snapshot of performance but may not fully reflect all investors’ experiences when cashflows vary, as it does not account for the timing of cashflows within the period.

Key characteristics of Internal Rate of Return

Internal Rate of Return represents the discount rate that equates the net present value of all cashflows from an investment to zero. It incorporates both the magnitude and timing of all cashflows. It is commonly used in private equity and real estate funds where capital contributions and withdrawals can be irregular.

US GAAP guidance

FASB ASC 946, Financial Services – Investment Companies establishes the accounting and reporting standards for financial highlights under US GAAP.

ASC 946-205-45-1 states that the overall objective of financial statements, including financial highlights, of investment companies, is to present net assets, results of operations, changes in net assets and financial highlights resulting from investment activities, and if applicable, from capital share transactions.
In reporting to shareholders, investment companies and investment companies registered with the Securities and Exchange Commission (“SEC”) are required to present the financial highlights as follows:

  • Non-registered investment companies must present financial highlights for the latest period consisting of per share operating performance, net investment income and expense ratios and total return for all investment companies organised in a manner using unitized net asset value.
  • Unitized net asset value represents the per unit value of a unitized fund and is calculated by dividing the fund’s net assets by the number of units outstanding.
  • Registered investment companies must present financial highlights for the latest five fiscal years. If a fund has been in operation for less than five years it must present financial highlights for each year since inception.
  • 946-205-45-2 states that for investment companies not using unitized net asset value, the financial highlights are presented and must consist of net investment income and expense ratios and total return or the internal rate of return since inception if applicable.

ASC 946-205-50-18 outlines the requirements for Total Return presentation “Total return shall be presented for all investment companies (for interim periods, the disclosure shall include whether or not total return is annualized)”.

As a result of the above, Total Return is the required presentation metric under ASC 946 used for investment companies unless the specific criteria for Internal Rate of Return presentation are met as per ASC 946-205-50-23. Where funds meet this criteria, Internal Rate of Return is presented instead of Total Return.

Total Return presentation

ASC 946 outlines the following for Total Return presentation when the investment company does not meet the specific requirements for Internal Rate of Return presentation under ASC 946-205-50-23.

  • 946-205-50-19 states that for non-registered investment companies using unitized net asset value, total return is calculated based on the change in the net asset value per share during the period under the assumption that all dividends are reinvested.
  • 946-205-50-20 states that for investment companies using unitized net asset value, including investment partnerships, total return is calculated based on the change in value during the period of a theoretical investment made at the beginning of the period. The change in value of a theoretical investment is measured by comparing the aggregate ending value of each class of investor with the aggregate beginning value of each such class, adjusted for any capital contributions or withdrawals during the period.
  • 946-205-50-21 states that if capital cashflows occur during the reporting period, returns are geometrically linked based on the capital cashflow data. Typically, geometric linking requires the computation of performance fees for each discrete period within a year in which the invested capital is constant (that is, for each period between investor cashflow dates), then multiplying these performance computations together to obtain the total return for a constant investment outstanding for the entire year. This approach prevents returns being distorted by the timing of subscriptions and redemptions.
  • 946-205-50-22 states that as performance allocations or fees may vary between investors within a class, total return for reporting classes that are subject to a performance allocation or fee must report total return before and after the performance allocation or fee for each reporting class as a whole. The effect of performance allocations on total return is calculated on a weighted average aggregate capital basis. This results in a performance calculation less than the maximum if, for example, certain partners had loss carryovers at the beginning of the period.

Exact presentation can vary based on the above due to investment companies that may have differing fee arrangements, however this presentation will remain in line with ASC 946-202-50-20 through ASC 946-205-50-22.

Criteria for Internal Rate of Return presentation

ASC 946-205-50-23 states that an investment company is required to disclose the internal rate of return since inception of the investment’s cash flows and ending net assets at the end of the period (i.e. the residual values) as presented in the financial statements, net of all performance allocations or fees, for each investor class, as of the beginning and end of the period, if they meet all of the following criteria as per their offering documents:

    • They have limited lives;
    • They do not continuously raise capital and are not required to redeem their interests upon investor request. Situations where initial capital commitments are obtained from investors at the time of organisation of the fund and subsequently drawing down those commitments to make investments is not considered continuous for this purpose;
    • They have as a prominent operating strategy, the return of proceeds from disposition of investments to investors;
    • They have limited opportunities, if any, for investors to withdraw before termination of the fund; and
    • They do not routinely acquire, either directly or indirectly, market-traded securities and derivative instruments as part of their investment strategy.

ASC 946-205-50-24 states that a footnote to the financial highlights must be included to disclose that the internal rate of return since inception of the investment is net of all incentives. The internal rate of return since inception should be based on a consistent assumption, no less than quarterly, as to the timing of cash inflows and outflows (for example on actual cashflow dates or cash inflows at the beginning of each month or quarter and cash outflows at the end of each month or quarter). All significant assumptions with respect to the internal rate of return must be included in the footnotes to the financial highlights.

Conclusion

Both Total Return and Internal Rate of Return are valuable performance metrics but their appropriateness under US GAAP depends on the nature and structure of the investment company under consideration. Total Return remains the most commonly applied metric under ASC 946 and offers simplicity, consistency and comparability in particular for funds with unitized net asset values and continuous capital activity.

Internal Rate of Return provides a more nuanced view of performance and incorporates the timing and magnitude of cash flows making it more relevant for closed end limited life funds such as private equity and real estate vehicles. Its use is restricted to circumstances where the specific criteria are met as per ASC 946-205-50-23 and it requires enhanced disclosures to ensure transparency.

For accounting professionals operating under US GAAP selecting the appropriate metric is not just a technical exercise but a critical reporting judgement. The fund’s characteristics must be evaluated along with investor activity and regulatory requirements to ensure that the chosen performance metric faithfully represents the economic reality of the investment and meets the informational needs of all stakeholders.
