The third bug is the "Falkirk Bug". This impacted one single branch so whether you would call it a "bug" in the system
as opposed to an isolated anomaly is open to debate. It was disclosed in the Castleton court proceedings — attached,
see para 23.

Reading the below from the Interim Report — it would appear there have been 3 bugs. Does anyone have the
definitive info on these?
The first defect, referred to as the "Receipts and Payments Mismatch Problem", impacted 62 branches. It was
discovered in September 2010 as a result of Fujitsu's monitoring of system events
(although there were subsequent calls from branches). The aggregate of the discrepancies arising from this system
defect was £9,029, the largest shortfall being £777 and the largest surplus £7,044.
POL has informed us that all shortages were addressed at no loss to any SPMR.
6.6. The second defect, referred to as the "Local Suspense Account Problem", affected 14 branches, and generated
discrepancies totalling £4,486, including a temporary shortfall of £9,800 at one branch and a surplus of £3,200 at
another (the remaining 12 branches were all impacted by amounts of less than £161).
6.7. POL was unaware of this second defect until, a year after its first occurrence in 2011, it re-occurred and an
unexplained shortfall was reported by an SPMR.
6.8. POL's initial investigations in 2012 failed to reveal the system defect and, because the cause could not be
identified, the amount was written off. Fujitsu looked into the matter early in 2013 and discovered, and then
corrected, the defect.
6.9. It seems however, that the shortfalls (and surpluses) that occurred at the first occurrence (in 2011) resulted in
branches being asked to make good incorrect amounts.
6.10. POL has informed us that it has disclosed, in Witness Statements to English Courts, information about one other
subsequently-corrected defect or “bug” in the Horizon software.
