NAV Accounting for Investment Funds
The Net Asset Value (NAV) is the cornerstone metric of any investment fund. It determines the price at which investors buy into the fund (subscription) and sell out of the fund (redemption). NAV accuracy is fundamental to investor protection, regulatory compliance, and the fund's reputation. In Mauritius, NAV calculation is typically performed by the fund administrator, an independent party separate from the fund manager.
The calculation involves valuing all of the fund's assets, deducting all liabilities and accrued expenses, and dividing the result by the number of outstanding shares or units. While this sounds straightforward, the complexity arises in asset valuation — particularly for funds holding illiquid investments, private equity positions, or emerging market securities where market prices may not be readily available.
The NAV Calculation Process
- Trade capture — All investment transactions (purchases, sales, income receipts) are recorded in the fund accounting system
- Position reconciliation — Fund positions are reconciled with custodian records to ensure all assets are accounted for
- Asset pricing — Each investment is valued using the appropriate methodology (market price, broker quote, model valuation)
- Income accrual — Dividends, interest, and other income are accrued based on ex-dates and record dates
- Expense accrual — Management fees, performance fees, custody fees, audit fees, and other expenses are accrued
- NAV computation — Total net assets are calculated and divided by outstanding shares/units
- Review and approval — The NAV is reviewed by senior staff and, in some cases, approved by the fund manager before publication
- Distribution — The NAV is published to investors, data vendors, and regulatory authorities
Valuation Methodologies
Listed Securities
Listed equities and bonds are valued at their closing market price on the relevant exchange on the valuation date. For securities listed on multiple exchanges, the fund's valuation policy specifies which exchange's price takes precedence. Closing prices are sourced from data vendors such as Bloomberg, Refinitiv, or exchange feeds.
Unlisted/Private Investments
For private equity, venture capital, and other unlisted investments, valuation follows IFRS 13 (Fair Value Measurement) and the International Private Equity and Venture Capital Valuation (IPEV) Guidelines. Common approaches include:
- Market approach — Comparable company multiples (EV/EBITDA, P/E, P/Revenue) applied to the investee's financials
- Income approach — Discounted cash flow (DCF) models using projected cash flows and appropriate discount rates
- Cost approach — Investment carried at cost, adjusted for impairment. Commonly used for recent investments (within 12 months)
- Last transaction price — Most recent arm's-length transaction price, adjusted for material changes
IFRS 13 Fair Value Hierarchy
| Level | Input Type | Examples |
|---|---|---|
| Level 1 | Quoted prices in active markets | Listed equities on major exchanges, government bonds |
| Level 2 | Observable inputs other than Level 1 | OTC derivatives, corporate bonds with limited trading, comparable transactions |
| Level 3 | Unobservable inputs (models) | Private equity, startup investments, illiquid assets |
Funds must disclose the fair value hierarchy classification of all investments in their financial statements and explain the valuation techniques and inputs used for Level 2 and Level 3 assets.
Special Valuation Considerations
Emerging Market Securities
Funds investing in African and Asian markets face specific valuation challenges: limited market liquidity, wide bid-ask spreads, delayed settlement, currency controls, and exchange closures on different public holidays. The fund's valuation policy must address these challenges with clear rules for stale pricing, last-traded pricing, and adjustment mechanisms.
Currency Valuation
Multi-currency funds must convert all holdings to the fund's base currency using consistent exchange rates. The valuation policy specifies the source of exchange rates (typically WM/Reuters closing rates) and the time of day at which rates are captured.
Side Pockets
For illiquid investments that cannot be fairly valued at each NAV date, the fund may establish side pocket arrangements. Side-pocketed investments are segregated from the main portfolio and valued separately, typically at a reduced or zero NAV, until a liquidity event allows accurate valuation. The offering document must specifically provide for side pocket mechanisms.
NAV Error Correction
NAV errors can occur due to pricing mistakes, incorrect accruals, missed transactions, or system issues. Mauritius fund administrators typically follow a materiality threshold approach:
- Immaterial errors (below the threshold, typically 0.5% of NAV) — Corrected in the next NAV calculation; no reprocessing of transactions
- Material errors (above the threshold) — Must be corrected, potentially with reprocessing of investor transactions, compensation for affected investors, and notification to the FSC
Robust quality control procedures — including four-eye review, automated pricing checks, and reconciliation processes — minimise the risk of NAV errors.
Shadow NAV
Some fund managers maintain a shadow NAV — an independent NAV calculation performed by the manager (or a separate service provider) to cross-check the administrator's official NAV. This provides an additional layer of oversight and early detection of potential errors. While not mandatory in Mauritius, shadow NAV is considered best practice for larger or more complex funds.
Reporting and Disclosure
- NAV publication — Published to investors and data vendors at the frequency specified in the offering document
- Financial statements — Annual audited financial statements prepared in accordance with IFRS, including investment schedule, fair value hierarchy disclosure, and risk analysis
- FSC quarterly return — Includes NAV data, AUM, investor counts, and other statistical information
- Investor statements — Regular statements showing each investor's holding value, transactions, and returns
Valuation Governance
Good valuation governance requires clear separation between the investment function (fund manager) and the valuation function (administrator). The fund's board should establish a valuation committee that oversees the valuation process, approves valuation policies, and reviews significant valuation judgments (particularly for Level 3 assets). This governance structure provides investor confidence and regulatory comfort.
