To prevent mismanagement, LETO created a Financial Committee (KasCo), which oversees all the financial affairs of the umbrella organization. Every once in a while, the KasCo can ask to check all these financial affairs. The committee is allowed to decide how much meetings are needed in a year to check all the financial affairs. The ones who are able to take place in the KasCo are the current and previous treasurers of the member associations.
In association year 2025-2026 the KasCo consists of the following members:
Vera van Kaam (SVN)
Loes Fijen (Sodalicium Classicum Noviomagense)
Rohan Ijdo (T.E.A., The English Association)
