Whereas the use of the formulae described in Article 1 (3) of Commission Decisions 95/238/EC to 95/248/EC (*) to convert the objectives of the programmes to units of GT could result in certain Member States being penalized for having begun the measurement of vessels in their fleets in units of GT prior to 1992 with a view to fulfilling with their obligations under Regulation (EEC) No 2930/86; Whereas for some Member States the definition of the GRT referred to in their multiannual guidance programmes was based on national units of tonnage; Whereas the tonnage of any vessel not measured in the units that were used to define the objectives of the programme must be estimated in this unit with the sole purpose of calculating on a consistent basis the situation of each segment of the fleets of the Member States with respect to the final objectives of their multiannual guidance programmes for the period 1992 to 1996; Whereas the formulae used to estimate missing tonnage values should be based on the data available in the fishing vessel register of the Community with regard to those vessels in each Member State that have been measured in both GT and in the units that were used to define the objectives of the programme; whereas these formulae may differ between Member States in consequence of differences in the composition of the fleets; Whereas for Sweden and Finland the objectives of the multiannual guidance programmes are expressed in GT and for Germany, Greece, Spain, France and Portugal, values of GRT have been declared to the fishing vessel () OJ No L 166, 15. 7. 1995, p. 1.
