%X We discuss nonperturbative renormalisation of the leading-twist flavour non-singlet operators needed for the calculation of the first and second moments of light-meson distribution ampli- tudes. On the lattice we use a regularisation-independent symmetric (or non-exceptional) mo- mentum scheme, RI/SMOM, which, for the second moment, allows us to include mixing with a total-derivative operator. We calculate the conversion functions needed to connect the RI/SMOM results to MSbar
