The official names of some organisations now consist of just the shortened form. The original name that was the basis for the shortened form is never used; it should not be included in the text or in the list of shortened forms:
AFS [formerly American Field Service]
KPMG [stands for Klynveld Peat Marwick Goerdeler]
RSPCA Australia [formerly Royal Society for the Prevention of Cruelty to Animals (Australia)]
UNICEF [formerly United Nations International Children’s Emergency Fund]
The shortened form for some other organisation names no longer fully reflects the original name, or reflects the organisation’s name in another language; these should be spelled out at first use, as usual:
United Nations Population Fund (UNFPA) [formerly United Nations Fund for Population Activities]
World Organisation for Animal Health (OIE) [Office International des Epizooties, in French]
Always check each organisation’s preferred official name and shortened form on their website or in their publications.
