The thread installs Wirecard as a case in which a trustee confirmation counted as cash until the banks of account, asked directly, called the papers spurious. The unresolved question is which repair, required while those confirmations were still being accepted, would have made the 18 June 2020 ad-hoc a non-event. Requiring the auditor to take a bank-originated confirmation under its own control, not a trustee PDF, is one rule: ISA 505 already says the auditor maintains control and selects the confirming party. Forbidding TPA escrow to be booked as cash unless the partner's books can be seen is a second: KPMG already could not take a position on 2016–2018 TPA revenue, and the 22 June ad-hoc already withdrew the description of that business. Treating a short-selling ban as something other than a cash exam is a third: BaFin's 18 February 2019 act names the price move after the reporting, not the escrow. Putting issuer financials into examination on risk in 2016–2018, instead of leaving FREP unselected, is a fourth: that is ESMA's monitoring finding. Those are not substitutes. Bank confirmations of empty accounts still fail if the TPA partners are fictional. Open partner books still fail if the cash sits in a trustee letter the bank never sent. A supervisor that examines the reports and still accepts trustee paper as a quarter of the balance sheet is still in the shape the post names. The 18 June ad-hoc, the 22 June ad-hoc, the Philippine central bank, BaFin's act, ESMA42-111-5349, KPMG as quoted, and Bundestag 19/30900 already record all four. They do not say which one, required when the trustee paper was still being filed as cash, would have kept a confirmation from becoming a DAX insolvency.
