Fund Accounting for Mutual Funds — A Practical Overview
Behind every NAV published at the end of a trading day sits a full accounting exercise — valuing every security, accruing every expense, and reconciling every cash movement, done fresh, every single business day, for every scheme an AMC runs. This is fund accounting, and getting it wrong even slightly has direct, visible consequences for every investor in the scheme.
What Fund Accounting Actually Involves
- Daily portfolio valuation — marking every security in the portfolio to its current fair value, following SEBI's prescribed valuation norms and, for debt instruments, the rates published by SEBI-approved valuation agencies.
- Income accrual — recognising interest income on debt holdings, dividend income on equity holdings, and other scheme income on an accrual basis (not just when cash is actually received), so the NAV reflects economically earned income even before it's physically credited.
- Expense accrual — daily accrual of the Total Expense Ratio components (management fees, RTA charges, custodian fees, and so on), ensuring the NAV reflects costs incurred to date rather than a lump-sum deduction at period end.
- Corporate action processing — accurately reflecting dividends, bonus issues, stock splits, rights issues, and similar events affecting portfolio holdings in both the security valuation and unit-holder records.
- NAV computation — the culmination of the above: (Total Assets − Total Liabilities) ÷ Units Outstanding, computed and disclosed by the regulatory deadline each business day.
- Fund-level and scheme-level reconciliation — ensuring cash movements (subscriptions, redemptions, security purchases and sales, expense payments) reconcile precisely against custodian records and bank statements, with any discrepancy investigated and resolved before NAV is finalised.
Why Daily Precision Matters So Much Here
Unlike a company's annual or quarterly financial statements, a mutual fund's "financial statement" — its NAV — is published and acted upon every single business day, and directly determines the price at which every investor buys or sells units that day. An accounting error that inflates or deflates NAV even marginally doesn't just misstate a report; it directly transfers value between investors transacting at the incorrect price and those who don't, making same-day accuracy a genuinely different order of operational discipline compared to periodic corporate accounting.
Who Actually Performs Fund Accounting
Fund accounting is typically handled by a dedicated fund accounting team within the AMC or, in many cases, outsourced to a specialised fund accounting service provider, working closely with the custodian (who holds and confirms the underlying securities and cash) and the valuation agencies (who supply independent pricing inputs for debt securities). The AMC's statutory auditor and the trustees both maintain oversight of this function, given its direct bearing on investor outcomes.
Where Errors Typically Originate
- Incorrect application of valuation methodology for illiquid or thinly traded securities.
- Missed or mistimed corporate action processing.
- Expense accrual errors, particularly around TER slab transitions as AUM crosses thresholds.
- Cut-off time misapplication, leading to the wrong day's NAV being applied to a transaction.
Why This Matters
Fund accounting is the operational engine that makes the entire promise of a mutual fund — a fair, transparent, daily-priced pooled investment — actually work in practice. For AMCs, the integrity of this function is not a back-office detail; it's the mechanism through which every investor's fair treatment is either delivered or quietly undermined.
How Anuj Desai & Associates Can Help
We conduct compliance audits of AMC fund accounting processes — valuation methodology application, expense accrual accuracy, and NAV error detection and rectification procedures — to identify gaps before they surface as investor-impacting NAV errors or SEBI observations. If your fund accounting controls haven't had an independent review, we can help.
