The amount of the guarantee is reviewed at the end of each year and, except in duly justified special circumstances, may not be less than the maximum amount of sums held on behalf of third parties during the previous guarantee period. This amount may also be revised during the period at the request of the guarantor or the operator if circumstances so justify.
For any revision of the amount of the guarantee, the subscriber must provide the guarantor with a statement issued by an external chartered accountant or auditor indicating the highest amount of sums held for third parties during the previous guarantee period. The guarantor may request, at any time, the register of payments or remittances provided for in the first paragraph of article R. 211-48, the register of mandates provided for in the third paragraph of article R. 211-49 and the full statement of account provided for in the second paragraph of article R. 211-48.
The guarantor must notify the registration commission mentioned in article L. 141-2 of any revision of the guarantee.
