Episode Details
Back to EpisodesNAV error threshold: back-solving reconciliation tolerances
Description
Who pays when a fund's NAV is wrong and the manager never saw the error? Under CSSF Circular 24/856 the investment fund manager corrects and compensates, even when the administrator calculated the price. The episode argues that managers should own one position and pricing record, backed by a written pricing policy, rather than inheriting whatever the administrator used.
Listeners learn to back-solve reconciliation tolerances from the 0.5% NAV materiality threshold for fixed income UCITS funds: a tenth of it per break for same-day ownership, a quarter of it in open breaks as a NAV gate. Also covered: the aggregation clause, EU T+1, Invesco's identifier consolidation, circular matching, Bloomberg pricing drift and the SEC's Madison Capital Funding settlement.
Key takeaways
- Set reconciliation tolerances from the fund's regulatory NAV error threshold instead of copying vendor default settings.
- Give any single break worth more than a tenth of the NAV threshold a named owner the same day.
- Do not release the NAV while open breaks add up to more than a quarter of the threshold, and log, own and approve any override.
- Check quantities against the custodian and prices against an independent challenger vendor, because IBOR matching the administrator can be two copies of the same mistake.
- Report breaks to the board as money against threshold, age of the oldest break and its owner, not as a raw count.
