The key question is materiality - in other words, whether any errors are significant. For a small business turning over £100k, an error of £10k is definitely material. For a business the size of Post Office, with a turnover of nearly £1bn, an error of £10k is unlikely to be material.
Indeed so. It seems that you are putting a Post Office management viewpoint - they were a large business therefore these sums weren't material. For the individual Post Offices those sums were material, and were material enough for the PO to bring prosecutions. I for one, just following this scandal have seen sums of £20,000, £36,000 etc. mentioned. Has anyone computed just how much people have paid up? There were c 900 people prosecuted so I could well imagine that it would total more than a million pounds which I think could be argued was material.
And OK so if no one claims the money, the organisation can eventually clear out their suspense account and take it as profit. But as yet, although I haven't read all the documents pertaining to this, it doesn't look as though a great deal of effort, if any, was expended in finding out where the money in the suspense account came from. Perhaps it could be argued that when the SPMs were querying the amounts they supposedly owed, they were in fact making a claim on the money.
