Årsagen til denne undtagelse er, at sektoren bliver mest berørt af, at man fjerner muligheden for støtte, og at man i højere grad risikerer forbedringer af sikkerheden, hvor de kun i mindre grad indvirker på kapaciteten.
The justification for this exception is that taking away the possibility of financial assistance is likely to bear hardest on the sector and put safety improvements more seriously at risk in circumstances where they are likely to have only minor effects on capacity.
