The Guarantee Scheme is a form of state aid and is subject to strict regulation. Guarantees covered by the de minimis aid are limited in amount and/or time. State aid is calculated as follows: guarantee amount x 2.6666666667% x duration of the guarantee. The total amount of de minimis aid granted to one enterprise may not exceed €200,000 over a period of three fiscal years. For enterprises operating in road haulage for third parties, this is 100,000 euros.
