Article 29
Valuation of MMFs
When using mark- to-market:
the asset of an MMF shall be valued at the more prudent side of bid and offer unless the asset can be closed out at mid-market;
only good quality market data shall be used; such data shall be assessed on the basis of all of the following factors:
the number and quality of the counterparties;
the volume and turnover in the market of the asset of the MMF;
the issue size and the portion of the issue that the MMF plans to buy or sell.
The model shall accurately estimate the intrinsic value of the asset of an MMF, based on all of the following up-to-date key factors:
the volume and turnover in the market of that asset;
the issue size and the portion of the issue that the MMF plans to buy or sell;
market risk, interest rate risk, credit risk attached to the asset.
When using mark-to-model, the amortised cost method shall not be used.
The amortised cost method shall only be used for valuing an asset of a LVNAV MMF in circumstances where the price of that asset calculated in accordance with paragraphs 2, 3 and 4 does not deviate from the price of that asset calculated in accordance with the first subparagraph of this paragraph by more than 10 basis points. In the event of such a deviation, the price of that asset shall be calculated in accordance with paragraphs 2, 3 and 4.
