The Prime Minister's call for investigation is the latest in a string of confusing statements and numbers about a town council and a computer management system -- we break it down and make it simple so you don't have to.

In a media release on the day the Town Council Management Report was released, AHTC chairman Sylvia Lim said the auditor's report was submitted later than usual. The longer-than-expected audit process was due to changing the auditor and the computer and financial system. The system had to be ready two months after the May general election for service and conservancy charges to be collected.

The previous system was terminated due to "material changes" as to who owns AHTC. The company in charge of the previous system, Action Information Management (AIM), took charge since January 2011 and sent the termination letter on June 22 2011.

Thus, AIM's disappearance became one of the main reasons why the audit report was not submitted in time, according to Lim.
