Investors are awaiting the release of acquisitive print and marketing company IVE Group's annual results after it took the unusual step of quietly disclosing $20 million of additional purchase payments.

Those payments, it appears, were not detailed when the company raised money from investors to help fund the purchase of two businesses in December last year. The omission has come to light at a critical time for IVE, which has expanded rapidly in its short time as a listed entity from private equity-backed origins, just as the escrow periods imposed on its remaining pre-IPO shareholders expire.
