Dear Mr Mistry
Re Branch Discrepancies

This letter follows on from telephone conversations between the Post
Office Finance Service Centre and yourself regarding certain discrepancies
which had been highlighted during branch trading routines at your office. I
would like to formally thank you for your assistance in helping us to
understand the sequence of events here from your branch perspective.
This has helped Post Office Ltd and our suppliers to determine the root
cause of the issue and to take action to resolve it.

The purpose of this letter is to summarise the outcomes of this review and
to confirm the remaining steps which we will be taking to conclude this
incident.

Our investigations have determined that there was an isolated error in the
data archiving process in Horizon. In very rare situations of a branch
deleting a stock unit at a particular point in time in the month, this
conflicted with the archiving process. It led to genuine loss or gain values
in the deleted stock unit, in an earlier year, reappearing on their
anniversary date in subsequent years.

This has impacted only 14 branches and we are communicating with all
parties concerned to confirm that the issue is understood and that proper
remedial action has been taken.

In summary, one of the stock units in your branch declared a loss of
£9,799.88 in December 2010 (Trading Period 9 TP9). The stock unit that

POL00145131
POL00145131
declared the discrepancy and placed it into Local Suspense was deleted on
or before 10th December 2010.

In the same period, other stock units in your branch reported net gains,
leading to a total net loss of £3,463.01 for your office for TP9. You then
followed the necessary steps to make good that loss.

In the normal course of events, the loss you had declared would have
moved smoothly through discrepancy accounts into Local Suspense and
through to settlement, with no recurrence in future periods. However, due
to the isolated system error and its impact when a branch deletes a stock
unit, the value of £9,799.88 reappeared in TP10 in the two following
years. Where there were other true losses and gains at that time, it
appeared as part of the net total.

In the interim, you have declared other gains and losses in the ordinary
course of business — a gain of £72.47 in 2012 and a loss £39.57 in 2013.
In light of the archiving issue, the net gain from these two matters (£32.90)
had been blocked centrally with the other values under investigation.

We will now rectify this by including the £32.90 in your next month’s
remuneration. This will not be taxable and general advice has been issued
to branches regarding the treatment of such non-taxable items on
remuneration slips.

In conclusion, we apologise for this incident and for any confusion and
concern it may have caused you.

We are pleased to confirm that the technical issue has been resolved and
the erroneous loss for your branch has been dealt with.

Yours sincerely
