Hi Rich. These are accountancy companies who vote on behalf of the creditors and, subsequently manage the "bad debt portfolio". To some extent, this isn't a bad thing, as they look purely at the situation from a numbers point of view.
Presumably they will work within a broad criteria framework, which might vary from company to company, but on the whole, if the proposal is the best their client will get they will vote yes.
My major voters were TiX (Insolvency Exchange) and KMPG, who all voted Yes, after modifying the fees and uplifting my payment by £28.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
