OeKB Sustainability Fund Index

OeSFX Calculation method

Minimum fund size

To be eligible for inclusion in the index, a fund must have assets under management of at least EUR 3 million (or the equivalent in foreign currency). If the size of a fund already included in the index falls to a level below EUR 2.5 million or its equivalent, the fund is deleted from the index.

Weighting

The funds in the index are weighted by their size in terms of assets under management, based on three size classes. The weighting factor is 1 for a fund size below EUR 30 million, 2 for a fund size from EUR 30 to 100 million, and 3 for a fund larger than EUR 100 million. Weightings in the index are rebalanced quarterly at the beginning of the quarter.

Funds with several tranches

For funds of which several tranches exist, only one tranche is used in the index calculation. This will be the tranche that comes closest to meeting the following criteria, listed in descending order of importance (if the data for the euro-denominated tranche is published): 1) investor segment: retail, 2) currency: euro, 3) accumulating: yes, 4) minimum investment: as low as possible.

Additions to and maintenance of index

Changes in the relative weights of the funds and in index composition are made quarterly, at the beginning of the quarter, with a notice period of one month.
The performance of funds newly added to the index is incorporated from the first day of the respective quarter. The performance of funds removed from the index is incorporated until and including the last day of the preceding quarter.
If no fund price exists for a calculation date, the last previous available price is used.

Effective calculation date

The index is calculated daily at 1 p.m. for the previous trading day and, if necessary, for any earlier trading days for which the index value requires correction (provided the data reaches OeKB within 15 calendar days of the date for which the index is to be corrected). The term “effective calculation date” refers to the date to which the calculation applies, not the date on which the calculation takes place.

Currency

The index is calculated in euros. Funds quoted in foreign currency are included at the euro reference exchange rate of the ECB at the effective calculation date.
If no euro reference exchange rate exists for a fund currency at that date, the previous available euro reference exchange rate is used. If previously unavailable euro reference exchange rates become available or if euro reference exchange rates are corrected (and provided that this data reaches OeKB within 15 calendar days of the effective calculation date), this new data is incorporated and thus results in a correction to the index.

Base value

The index starts at a base value of 1,000 at the inception date of December 30, 2004.

Corrections to index

Corrections to or delayed deliveries of prices as well as distributions by funds contained in the index are incorporated into the calculation and thus lead to a correction of the index value, provided that the information reaches OeKB within 15 calendar days of the effective calculation date.
