  Modules over a vertex operator algebra V give rise to sheaves of coinvariants
on moduli of stable pointed curves. If V satisfies finiteness and
semi-simplicity conditions, these sheaves are vector bundles. This relies on
factorization, an isomorphism of spaces of coinvariants at a nodal curve with a
finite sum of analogous spaces on the normalization of the curve. Here we
introduce the notion of a factorization presentation, and using this, we show
that finiteness conditions on V imply the sheaves of coinvariants are coherent
on moduli spaces of pointed stable curves without any assumption of
semisimplicity.
