2. Standard MMFs shall be allowed to invest in a money market instrument that undergoes regular yield adjustments in line with money market conditions every 397 days or on a more frequent basis while not having a residual maturity exceeding two years.

The UK maintained that the Commission’s reference interest rates were not a valid comparator for the rates on the 2001 loan, in particular because the Commission’s rates are based on five year maturity dates and the loan in question consisted of long-term debt with a range of maturity dates between 20 and 25 years, because the loan advanced to Royal Mail reflected commercial rates available to similarly positioned long-term borrowers, and because the UK yield curve in 1999-2000 (the relevant period for calculating interest) was moving downwards making corporate borrowing cheaper.

According to Italy, as we have seen, the stable component of the deposit, which is of a long-term nature, is reflected in the long-term element of the loan rate (90 %, made up of (i) 10 % linked to the yield of the 10-year multiannual Treasury bond, and (ii) 80 % linked to the yield of the 30-year multiannual Treasury bond).

it must, with a view to achieving that primary investment objective, invest exclusively in high quality money market instruments with a maturity or residual maturity of no more than 397 days, or regular yield adjustments consistent with such a maturity, and with a weighted average maturity of 60 days.

"Effective Maturity under the Internal Model Method, for a netting set with maturity greater than one year" means the ratio of the sum of expected exposure over the life of the transactions in the netting set discounted at the risk-free rate of return divided by the sum of expected exposure over one year in a netting set discounted at the risk-free rate.

However, when maturity analysis is important, such as for analysis of interest rates and asset yields, a breakdown of a range of maturities may be required.
