Up to April 1, 1972 there were about 50 Waldi licensees. The Waldi producers had to pay a minimum licensing fee in advance. The task of the OC was not so much to acquire new contracts, as rather to promote sales volume in order to profit from higher licensing income.

Minimum licensing fees        245,000,- DM
Additional licensing fees      213,000,- DM
                                          458,000,- DM

Two million Waldis have been sold in about 20 countries. At this time almost all Waldi producers have paid licensing fees in excess of the pre-paid minimum.
