hi dig,
i see a value of $1.8m in pledged receivables in the balance sheet at y/e.
to me, that looks like enough room for the $1.7m from basf.
but one way or another, wave took $1.5m in q4 against receivables which are likely to have been remitted in q1.
so i think you are giving wave about $1.5m more than they will keep.
but heck, it probably isn't worth the effort given all the moving parts.
