Extended case
Liquidity return rebuild under a fixed BOT window
A Bangkok commercial bank asked us to audit its liquidity reporting application two months before a template change. Preparers had inherited worksheets with undocumented overlays from a prior core-system migration. We sampled high-value lines, traced overnight positions to treasury extracts, and isolated three manual bridges that reversed incorrectly on month-end holidays.
Outcome: Management cleared the bridges before freeze; the management letter flagged one residual evidence gap on branch cash that internal audit later owned.
