SUMMARY

This report concerns a claim by Post Office Limited against Lee Castleton (“Mr

Castleton”) who was the sub-postmaster at Marine Drive, Bridlington from July
2003 to March 2004. The Post Office claim that they have suffered losses of

£25,858.95 at the branch which Mr Castleton is responsible for under the terms of

his contract. I have been asked to investigate these losses. Mr Castleton has

blamed the losses on problems with the Post Office computer system used in sub-

post offices.

My conclusions can be summarised as follows:

(a)

(b)

(©)

(d)

The only indications of possible computer problems that are apparent from
the accounting records are three very small differences in the cash account

(trial balance) but each are less than £5. This is discussed in section 6.2.

Mr Castleton had to make a declaration of the cash in hand at the end of
each day. He entered the figure he said he had at the sub-post office,
showing in detail the amount of notes and coins of different denominations.
Comparing the changes in these figures with the cash account movement for
the day there are significant differences every day in the two months I have
looked at in detail. These suggest Mr Castleton was not recording his cash

balance correctly. This is discussed in section 6.4.

On two occasions in the period I have reviewed Mr Castleton was notified
of errors which resulted in him owing the Post Office £1,349 and £862 for
past mistakes, There is no indication that he made good these amounts. This

is discussed in section 10.3.

I have concerns that Mr Castleton was inadvertently overstating his
differences by not understanding how the suspense account was supposed to
operate. It appears that he has treated £3,509 as a loss which is still in
suspense. This looks like double-counting and if so would overstate the

amount of the Post Office claim. This is discussed in section 5.5.

(e)

There is a suggestion by a Mr John Jones of the Post Office that Mr
Castleton had omitted receipts from a car auction customer which paid in
large amounts in cash to its Girobank account. My conclusions are that the
three large amounts that Mr Jones refers to were correctly dealt with in the
cash account. This is discussed in section 7. There is a separate point, which
is not part of my investigation, as to whether Mr Castleton has been over-
ordering cash from the Post Office because of the uncertainties as to how
much money the auction would pay in each week. Throughout most of
January and February 2004 Mr Castleton seems to have far to much money

for his normal requirements to pay pensions etc.

3 INTRODUCTION AND TERMS OF REFERENCE
Instructions

3.1.1 I have been instructed by Bond Pearce on behalf of the claimant, Post Office

Limited to prepare an expert accountant’s report.

3.1.2 I have been asked to investigate whether the Post Office suffered a loss of
£25,858.95 as a result of Mr Castleton’s actions. I have been asked us to focus on

the issue of whether the losses can be proved arithmetically.

3.1.3 I do not act as accountant to either party to the claim and except where specified I
have carried out no audit or verification work in relation to the information on

which I have relied.
Confidentiality

3.1.4 This document has been prepared strictly for use in the claim by the claimant. I
understand that it will be made available to the claimant, her legal advisors, other
parties connected with the action and the Court. In all other respects, this report is
confidential and should not be used, reproduced, or circulated for any other
purpose, in whole, or in part, without my prior written consent. I will not accept

liability to any party other than the claimant.
Legal and factual issues

3.1.5 Although the report is prepared for instructing solicitors and counsel solely for the
purpose of this particular action, my overriding duty is to express an honest and
unbiased opinion to assist the Court. I have prepared this report as if instructed by

the Court.

3.1.6 This report should not be read as expressing any opinion on factual matters which
depend on disputed testimony of the witnesses of fact, or legal issues, although it

inevitably reflects my understanding of the position.

Preparation of report

3.1.7. I have written this report myself and so the opinions expressed are my own.
Where I have received assistance, I have supervised the staff concerned. The

individual who has assisted me in preparing this report was:
e Elizabeth Padley FCCA— forensic manager

3.1.8 In preparing some of the appendices to this report I have used Excel on Dell
Personal Computers and minimal arithmetic errors may occur within the computer

programs as a result of rounding.

3.1.9 Any opinions or views expressed in this report are subject to any further

information which may be made available to me and in this sense are provisional.

3.2 SOURCES OF INFORMATION

3.2.1 [have been provided with a large amount of photocopied documents relating to
the Marine Drive sub-post office. These include copies of the weekly cash
accounts and many of the control prints produced from the Horizon computer
system. Many of these documents are timed and dated and show the computer log

in code for the individual that printed the report.

3.2.2 The records that I have seen generally cover a period from the week ending 24
December 2003 (Post Office accounting week 39), which was the first time that
Mr Castleton reported a problem with his accounts to the week ended 17 March
2004 (week 51). Mr Castleton was suspended during the following week (week
52). Ihave also seen some records during the subsequent period from weeks 1 to 6
of 2004-05 when the sub-post office was being operated by two temporary sub-

postmasters following Mr Castleton’s suspension.

3.2.3. I have also been provided with Excel spreadsheets (and printed copies) of the
transaction and events records from Horizon for Marine Drive for the months of

January, February and March 2004.

Draft report dated: 29 November 2006

3.2.4 Ihave seen the witness statements from various Post Office employees explaining
various aspects of the operation of the sub-post office and their investigations into

Mr Castleton’s affairs.

3.2.5 The Post Office have produced detailed manuals showing staff how to operate the
Horizon accounting system. I have been given copies of manuals which I am told

are the versions in force when Mr Castleton was at Marine Drive.

3.2.6 In appendix 1 I have summarised the Post Office’s claim against Mr Castleton
which amounts to £25,858.95.

4 BACKGROUND INFORMATION

4.1 The Marine Drive sub-post office

4.1.1 [have not been able to visit the Marine Drive sub-post office but I understand that

itis one of a number of such offices in Bridlington.

4.1.2 T understand that the sub-post office is situated within a shop that was being run
by Mr Castleton. During the period that the sub-post office was run by Mr
Castleton there appear to have been three individuals working in the post office
part of the business, Mr Castleton, Mrs Christine Train and an assistant (Rita). The
sub-post office was open from Monday to Friday and on Saturday mornings. It
would appear that typically Mrs Train worked full time and Rita mornings only
during the week. Mr Castleton appears to have worked most days and often
covered Mrs Train’s lunch break. On Saturday mornings only one person operated

the sub-post office.

4.1.3 Sub-post offices provide a variety of services which vary according to their
location. For example Marine Drive provided some parcel facilities but did not
issue motor vehicle licences. Marine Drive is near to the town centre where there
is a main post office. In monetary terms by far the largest part of Marine Drive’s
work was the payment of pensions and benefits. This would include the payment

of retirement pensions, tax credits and other family benefits.

4.1.4 In value terms postal transactions generated only a relatively small amount of
revenue. The period that I have reviewed covers the winter months and as
Bridlington is a seaside resort there may be a different pattern of business in the

summer months.

4.1.5 Marine Drive carried out a variety of banking transactions, including:
(a) Accepting deposits from Girobank customers;
(b) Accepting deposits from Alliance & Leicester customers;

(c) Receiving payments for National Savings & Investment products (e.g.

savings certificates and premium bonds);

Expert Report by Geoffrey W Porter
I Rare nme Draft report dated: 29 November 2006

4.1.6

(d) Paying out money to Alliance & Leicester customers; and
(e) Paying out money to Post Office Card Account holders.

The Girobank deposits represent the largest amounts of receipts from customers at
Marine Drive. Girobank accounts are often used by business customers because
the Post Office is willing to accept cash bankings, which it can then use to pay
pensions and benefits, unlike the High Street banks who will often charge
businesses for dealing with cash. In addition money was accepted from the public

for the payment of utility bills and other services.

Business at the sub-post office was carried out predominately in cash, There were
some cheque receipts from customers amounting to about £5,500 per week. The
basic procedure is that a cheque payment for say a television licence is entered in
the Horizon computer system and the cheque is then sent to a central processing
centre. There is then a checking procedure to detect errors as discussed in section
10.5. In addition to cheques there are a very small number of debit card payments,
averaging less than £200 per week, which because of their small size I have not
considered further. The great majority of transactions in both number and value

take place in cash.

During the thirteen weeks before Mr Castleton’s suspension the average
transactions at Marine Drive were that it paid out almost £70,000 in cash for
pensions and benefits each week. About half of the cash required for this came
from the banking receipts but an average of £35,000 per week had to be sent in
cash to Marine Drive by the Post Office. I understand that Mr Castleton’s

operation of the cash ordering system were a matter for concern.

4.2 The Horizon computer system

4.2.1 The Post Office has introduced a standard computer system called Horizon at all
of its branch offices including Marine Drive. Each branch is linked to a central
computer but operates separately and importantly produces its own accounts
which the sub-postmaster has to balance regularly. I understand that Marine Drive
has two counter positions in the post office but they were not operated separately
by Mr Castleton. He had the opportunity to operate the units separately, which
might have given him more control over his staff, but he chose not to do so. I

discuss the operation of Horizon further in section 5.

4.2.2 In appendix 2 I have summarised the cash account for Marine Drive from the

Horizon records.

4.3 Stock

4.3.1 A sub-post office such as Marine Drive carries a stock of postal items such as
stamps and postal orders. The pattern of stock carried by a sub-post office has
changed in recent years. The facility for the Horizon computer system to print
postal labels has reduced the need to keep stocks of stamps. However there are
new stock lines such as phone cards. Marine Drive had a National Lottery

franchise and the stock included instant lottery tickets.

4.3.2 Typically Marine Drive had around £6,000 in stock (excluding lottery tickets)
made up of around £4,000 in stamps, £1,000 in postal orders and £1,000 in phone

cards and television and vehicles licence stamps.

4.3.3 The Horizon records show that Mr Castleton held around £2,000 in National
Lottery instant tickets (page 5 of appendix 2). However during the audit in week
§2 the Post Office auditors discovered a discrepancy of £1,769 (see appendix 1).
As can be seen from page 11 of appendix 2 the stock of lottery tickets held by the
temporary postmasters after Mr Castleton’s suspension was less than £700. It is

not known when this discrepancy arose.

Staff

Looking through the events logs for January to March 2004 there are four users on
the system (excluding what appear to have been various entries by the auditors in
March) namely LCA001 (Lee Castleton) , RSP001, CTROO1 and CTRO02. CTR is
Christine Train but it is not clear why she has two log on codes. There seem to be
days when she is logged on under both codes. In the file there is a list of users
which shows that RSP has access as a Clerk but LCA and CTR are down as

Managers.

5 BALANCING HORIZON AND DEALING WITH DIFFERENCES
S.A Accounting by sub-postmasters

5.1.1 A sub-postmaster is entrusted with a considerable amount of cash and valuable
stock and the Post Office has systems which ensure that meticulous accounts are

kept.

5.1.2 It is a fundamental part of the contract with the Post Office that each sub-
postmaster is responsible for losses incurred at his or her branch. The system
therefore aims to ensure that the sub-postmaster records all transactions carefully
and accurately, reconciles the cash and stock held regularly and reports any

differences promptly.

5.2 An overview of Horizon

5.2.1 The Horizon accounting system is intended to control all of the cash and stock
that the sub-postmaster holds within the branch. All financial activities within the
sub-post office have to be recorded in the system. Each transaction should be a
double entry accounting basis, for example that sale of a postage stamp for cash

will show in Horizon as a sale and as an increase in the cash balance.
5.2.2 The transactions that Horizon records include:

(a) Sales of stamps and other products;

(b) Payments of pensions and benefits;

(c) Banking receipts and payments;

(d) The receipt of cash from the Post Office;

(e) The receipt of stocks of stamps and postal orders;

(f) The remittance of cheques received from customers to the Post Office

clearing house;

(g) Sales of National Lottery tickets and the payment of cash prizes to winner;

Expert Report by Geoffrey W Porter
intel Draft report dated: 29 November 2006

(h) Foreign currency received from the Post Office for customer orders and any

exchange differences whilst the currency is held at the branch;
(i) Returns of damaged notes and coins to the Post Office.

5.2.3. The system is designed to record all financial transactions at the post office.

5.3 Balancing the books

5.3.1 A sub-postmaster has to balance his or her accounting records regularly. He has to
show to the Post Office that he has controlled the cash and stock entrusted to him

and has accounted for it properly.

5.3.2 At the time Mr Castleton was at Marine Drive the basic system involved a formal
weekly reconciliation of the records carried on at the close of business on
Wednesday. Essentially this simply involved counting the cash and stock held at
the branch and comparing it with the record maintained by Horizon. If all
transactions have been correctly recorded in Horizon and the sub-post office staff
have not made any mistakes then the cash stock held should equal the balance per

the system.

5.3.3 As Horizon is a computerised system, the sub-postmaster has to make a cash
declaration by entering the cash held into the system each week. In doing so he is

telling the Post Office “this is the amount of cash I have”.

5.3.4 Clearly with any retail business that deals with large numbers of cash transactions
there will be mistakes. Staff may give wrong change or perhaps give the wrong
number of stamps, giving the customer fifty stamps but charging for forty.
However staff employed in post offices usually are skilled at cash handling and
have good arithmetic abilities and mistakes should normally be small. Mr
Castleton was recording differences of less than £1 in the first four weeks returns
that I have seen (page 5 of appendix 2) and the temporary staff employed after his
suspension were achieving differences of less than £20 in most weeks (page 11 of

appendix 2).

5.3.5 Operating a modern computer system such as Horizon should reduce the scope for

5.4
5.4.1

staff error. Many transactions are dealt with by scanning bar codes on products
such as books of stamps and other products are entered by using a touch screen
system where the clerk selects the item sold from a picture menu. The need to add
up the price stamps sold and similar manual entries should be eliminated. There is
also a simplification in that Horizon prints postage labels which eliminates the
need to use high value stamps for parcels etc. Clearly this will never eliminate the
possibility that a clerk may give the wrong change or pay out too much in

pensions.

Dealing with gains and losses

The Horizon manual explains to the sub-postmaster how to deal with gains and

losses on balancing. At page 77 of Balancing with Horizon it simply says:

Making Good Losses

If you have not obtained authority to hold a loss within the Suspense Account, you will
need to make good the discrepancy after the final stock unit has rolled to the next CAP.
Make good the loss

* This involves placing the cash for the amount of the loss in your till

Similarly sub-postmasters are told to remove cash from the till to eliminate any
gain. After adjusting for any gain or loss the sub-postmaster then makes a new
cash declaration stating the corrected amount of cash held and this is carried
forward to the next week. Using this procedure Mr Castleton would have been

able to deal with the small day to day differences that arose each week.

Expert Report by Geoffrey W Porter

5.4.3. Where a sub-postmaster has a loss that he or she is unable to immediately make
up from their own cash then there is the facility of making a temporary transfer to
a loss account in which the amount can be held until the sub-postmaster has
arranged funds to make good the loss. In the Horizon system this is done by
making a transfer from the cash account to account “223 Loss A posted to Table 2a”
which name is a reference to the weekly cash accounts which is divided into sections
known as tables. Where a loss is cleared a corresponding transfer back to cash is made

from account “221 Loss A redeemed from Table 2a”.

5.4.4 Mr Castleton made two transfers to account 223 of £8,243.10 in week 47 and
£3,509.68 in week 49. The loss account and the suspense account (see 5.Sbelow)
are summarised in appendix 3. I discuss the second transfer further at 5.5.4

below.

5.5 The suspense account

5.5.1 Where a sub-postmaster has a loss or gain that he or she considers abnormal there
is a facility to transfer the difference to a suspense account which will allow it to
be investigated without the need for the sub-postmaster to immediately pay in

cash to cover the loss.

5.5.2 There is a formal procedure for using the suspense account and there are
restrictions as to the items that should be transferred into it. In particular use of the

suspense account in some case required the authorisation of a manager.

5.5.3 The sub-postmaster can make a transfer of a shortage to suspense through Horizon
which will have the effect of making an adjustment between the cash account and
Horizon account “222 Shortage Discrepancy (Suspense)”. Using the suspense account
is intended to be a temporary measure. When the sub-postmaster resolves the query a
further adjustment is made between the cash account and Horizon account “145 Surplus

Discrepancy (suspense)”. Accounts 222 and 145 would then cancel each other.

Expert Report by Geoffrey W Porter

Draft report dated: 29 November 2006

Mr Castleton has used both codes and I have concerns that he did not understand
how to use these accounts. I note the week 49 transfer on 27 February is a very
similar amount to a sum of £3,509.18 which Mr Castleton had transferred to
suspense account on the previous day (page 1 of appendix 3). My view is that this
may be a duplication as I would have expected to see a transfer out of suspense

before the transfer to the loss account was made.

6 REVIEW OF THE TRANSACTION LISTINGS RECORDS
6.1 The Horizon transactions listings

6.1.1 The Horizon system records every accounting transaction at a post office from the
sale of a single postage stamp to the receipt of cash for the weekly payment of
pensions. The system operates on a double entry system from which it is possible

to extract a trial balance in the form of a weekly cash account.

6.1.2 have been given Excel spreadsheets which are the detailed transactions for the
Marine Drive sub-post office for the months of January , February and March
2004.

6.2 Addition errors

6.2.1 I have looked at the three transactions spreadsheets and observe that two out of
the three (January and February) do not add up by small amounts of £2.47 and
£4.05. I have identified that the £2.47 falls in week 42 (the period Mr Castleton
has tried to reconcile manually) and that it is represented by two separate amounts

of 92p on 12 January and £1.55 on 15 January.
6.2.2 A possible explanation for this seems to:

(a) 2p is posted as a Royal Mail Label - International Air (code 4342) and is
followed by £1.84 cash. This could suggest that two labels were issued but

only one has gone through?

(b) £1.55 is posted as a Royal Mail Label - Inland Second Class (code 4341)
and is followed by a Royal Mail Label - International Air (code 4342) and
then a series of other 4341 transactions that are cleared by cash of £19.78.

The transactions only add up to £18.23 including the £1.55

It occurs to me that the Royal Mail Label - International Air (code 4342)
transactions are relatively unusual and I wonder if the explanation is that the clerk
intended to input two Royal Mail Label - Inland Second Class (code 4341) and
instead of 4341 twice the system has picked up the entry as one 4342 but has lost

[eeamnerscrmennt Draft report dated: 29 November 2006

the second 4341? I note that the first transaction was carried out by Mrs Train and

the second by Mr Castleton.

6.2.3 The £4.05 in February can be identified as being as a cash receipt at 16.51 on 4
February 2004 by CTROO1 (Mrs Train) for which there is no debit. A little while
later at 17.07 there is a £4.05 debit and credit again by CTROOI. The debit is a
code 4 which is “Redeemed vouchers to CRU”. It is possible that Mrs Train was
trying to reconcile the records and entered the cash twice but should not the

system have shown an error?

6.2.4 I do not have an explanation for these errors but my review of the transactions

listings for the three months has given no indication of any other errors.

6.3 Lottery Sales

6.3.1 Mr Castleton had an a National Lottery outlet at Marine Drive. There appears to
be scope for him making errors in this area, My understanding is that the National
Lottery terminal was in Mr Castleton’s shop but he was required to account for the

lottery transactions through Horizon.

6.3.2 From the transactions listing that National Lottery sales (Horizon code 251)
appear generally as a small group of transactions once a day. The system does not
show large numbers of small transactions for sales of individual tickets. I assume
therefore that Mr Castleton paid the lottery sales into his shop till and then once a
day, typically first thing in the morning, took the money from the shop till and put

it in the post office till.

6.3.3 There are clearly opportunities for errors in such transactions, most notably that
Mr Castleton may have taken the wrong amount out of his shop till so that there is

a difference between his cash received and the sales recorded on Horizon.

6.3.4 There may also be the possibility that Mr Castleton made mistakes when paying
out prizes to lottery winners, either in the cash transfer or in entering the
transactions in Horizon. It may for example be possible to enter a lottery prize

paid out as if it were a lottery sale.

6.3.5 At the time of the March 2004 audit of Mr Castleton’s affairs the auditor noted a
discrepancy of £1,769 re the lottery. This appears to relate to the stock of instant
lottery tickets. In the weeks before the audit Mr Castleton had recorded the stock
at between £1,400 and £2,800, the balance at 10 March 2004 being shown as
£2,315. In the next week the stock was £527 and thereafter the stock remained at

less than £700, after Mr Castleton had been suspended.

6.4 Cash declarations

6.4.1 In the Horizon system Mr Castleton was required to enter the closing cash in hand
each day. This is a detailed declaration requiring the cash to be entered by

individual denomination of note and coin.

6.4.2 In the Horizon system nominal code 1 is cash. For the months of January and
February 2004 I have totalled the net cash movement for each day. I have then
prepared a summary in appendix 4 for January and appendix 5 for February that
takes Mr Castleton’s last cash declaration for the previous month and then adds or
subtracts the net cash movement for each day. I then compared the total that this
produced with the cash declared at the end of the next day by Mr Castleton. This

summary should help to identify on which day Mr Castleton’s differences arise.

6.4.3 As can be seen from appendices 4 and 5 the calculated cash balance never agreed
with the balance declared by Mr Castleton. Furthermore the discrepancy between
the figures changes every day. I would not expect this to happen particularly on
Saturdays when the post office was only open in the morning and had only a small
volume of transactions. This suggests to be that Mr Castleton’s daily cash

counting may not have been accurate.

6.4.4 If Mr Castleton had suffered from a problem with the Horizon computer system I

would have expected to see that he was reporting a daily cash balance that
suddenly fell below the cumulative calculated cash balance (as calculated in
appendices 4 and 5) but that looking at the daily balances up to the next
Wednesday there would be the same difference (or at least a very close one) until
the weekly reconciliation was performed. There is no indication that this was

happening in January and February 2004 at Marine Drive.

7 ERRORS IN RECORDING RECEIPTS

7A Incorrect cash declarations

7.1.1 Inhis witness statement Mr John Jones of the Post Office comments at paragraph

12 about incorrect cash declarations.

7.1.2 Mr Jones refers to receipts into a customer’s account reference 685 9461. I have
examined the available information on this account covering the points that Mr

Jones raises.

7.1.3 In his Daily Analysis - Cash Account for weeks 46, 47 & 50 [document 55] Mr
Jones suggests that the three receipts were excluded from the weekly cash

balances declared by Mr Castleton.

7.1.4 Ihave given photocopies of Giro Deposits — Office Copy slips which would

appear to be printouts from the Horizon computer.

(a) Report dated 11 February 2004 timed at 16.20 shows a receipt of £16,537.25
for account 6859461.

(b) Report dated 18 February 2004 timed at 17.04 shows a receipt of
£12,000.00 for account 6859461.

(c) Report dated 10 March 2004 timed at 16.46 shows a receipt of £12,000.00
for account 6859461.

7.1.5 From the detailed transaction listings these amounts can be seen to be entered into

Horizon as follows:

(a) £16,537.25 at 15.08 on 11 February 2004 (entry by CTR002) posted to code
262 [Note that CTRO01 is also in use as well as RSPOO1]

(b) £12,000 at 13.26 on 18 February 2004 (entry by LCA001) posted to code
262

(c) £12,000 at 11.55 on 10 March 2004 (entry by RSP001) posted to code 262.

7.1.6 I firstly consider the February receipts which are covered by summary of cash

TAAL

movements in appendix 5. If Mr Jones is correct then I would have expected to
see that Mr Castleton’s daily cash declaration for the Wednesday to be much
lower than the cumulative balance calculated from the recorded cash transactions.
Also the normal pattern of transactions is that a sub-post office pays such as
Marine Drive out cash each day so that I would expect the cash balance to
decrease except for Thursdays when a remittance is usually sent by the Post
Office. An increase in the daily balance, other than on a Thursday, implies that
there has been a significant Girobank or similar banking of cash. This is not

affected by money received in the form of cheques.

Mr Castleton has made end of day cash declarations of £24,602.27 on Tuesday 10
February and £33,100.41 on Wednesday 11 February.

On 12 February Mr Castleton received £70,000 from the Post Office so his
declaration that day is much higher at £98,751.60.

Mr Castleton has made end of day cash declarations of £74,939.85 on Tuesday 17
February and £80,337.44 on Wednesday 18 February.

On 19 February Mr Castleton received £1,020 from the Post Office but paid
£20,158.75 back implying that at this point he had too much cash. His daily
declaration was £47,729.62.

My conclusions regarding the two February bankings are that they are entered in
Horizon on the right day and the cash account increases on both days. Mr
Castleton would therefore appear to have dealt with them properly as regards the
entries in Horizon. There is a separate questions, which is outside of the matters
covered by my report, as to whether Mr Castleton was ordering too much cash
from the Post Office. The £70,000 remittance on 12 February appears excessive

and as noted above Mr Castleton paid cash back to the Post Office the next week.

March

Ihave seen a Weekly Cash Flow — Office Copy dated 17.55 on 10 March 2004
(produced by CTRO02) [document 3] which gives the following daily totals for
the third of the weeks reviewed by Mr Jones:

£
Thursday 58,724.97
Friday 67,419.36
Saturday 70,870.41
Sunday 70,870.41
Monday 42,845.11
Tuesday 37,412.67
Wednesday 48,943.65

Ihave some daily Cash on Hand — Office Copy prints which cover the Saturday,
Monday and Tuesday but not the Wednesday. I also have a copy of Thursday 11
March when the balance was £49,374.15. This is timed at 07.54 and apparently
superseded the previous night’s balance of £48,943.65, an increase of £430.50.

The 17 March 2004 Cash Account (final) shows that £25,000 was received in
Remittances from ADC.. This is entered into Horizon at 14.59 on 11 March 2004
by LCAO01. By the end of business on 11 March the cash declared had increased
to £61,321.49 which implies that the net cash movement for the day was that the
sub-post office had paid out £13,053. 11 March was a Thursday, normally the
busiest day of the week for paying pensions. Reviewing the transactions for
March I note that payments of pensions (nominal codes 177 to 185) amount to
£12,743 on 11 March.

From this check I conclude that the £12,000 receipt on 10 March was included in

the cash declared.

TAAT

In his witness statement Mr Gregory Booth, who was the temporary sub-
postmaster after Mr Castleton was suspended refers to the customer for account
6859461. He explains that it was car auction in Bridlington and that during the
period he operated the sub-post office the client would usually deposit around
£15,000 to £20,000 in cash each week in one or two tranches, being by far the
largest amount that the Marine Drive branch would receive in cash deposits each
week. Mr Booth states that he never met the customer, the cash usually being left
with Mr Castleton in the shop early in the morning before the post office counter
opened. Mr Booth states that the cash was left in bag or boxes and there was no
covering note stating how much cash there was; it was simply left to the Marine
Drive branch to count and to pay into the customer’s Girobank account. Mr Booth
says that the paying in book was kept permanently behind the post office counter

whereas it should have been retained by the customer.

Although this is an unsatisfactory way of operating it ought not to impact on the
accounting system provided that the money was counted correctly and the

banking then entered accurately in Horizon.

8 REVIEW OF THE ACCOUNTING RECORDS
8.1 Introduction

8.1.1 [have reviewed the accounting records that I have been given to see if there are

any apparent reasons for the differences which Mr Castleton has recorded.

8.2 Weeks prior to week 39 (ended 24 December 2003)

8.2.1 Tam not aware of any differences that arose prior to week 39,

8.3 Week 39 (ended 24 December 2003)

8.3.1 Mr Castleton’s line manager, Catherine Oglesby, explains in her witness statement
that between approximately Christmas and New Year 2003 Mr Castleton
telephoned her to say that he was £1,100 short in his cash account for week 39.
Catherine Oglesby comments that this was the first time since Mr Castleton took

over the post office in July 2003 that he had any major problems in balancing.

8.3.2 Catherine Oglesby paid a routine visit to Marine Drive on 16 January 2004 and at

that time no explanation of the week 39 difference had come to light.

8.3.3 On 14 January 2004 (week 42) the final Horizon entry of the day (by CTRO02) is
to post £1,103.13 to code 222 suspense. One of the first entries for the next day,
15 January is a receipt of £1,103.00 posted to code 145 Surplus Discrepancy
(suspense). I assume that at this point Mr Castleton paid in cash to cover the

difference.

8.3.4 It is not clear what these entries mean. It could be interpreted that Mr Castleton
was still looking for the loss and had decided to put it to suspense but changed his

mind overnight.

Draft report dated: 29 November 2006

8.3.5 There is no indication as to how Mr Castleton dealt with the week 39 difference
and when he paid the cash in. The normal procedure as explained at section 5.4 is
that the sub-postmaster is required to put in his or her own cash to make up a
shortfall. This should have been done when week 39 was balanced. If Mr
Castleton did not make up the shortage until late then he should have asked to
make a transfer to suspense. As he did not there is an implication that his cash
declarations at the end of weeks 40 and 41 were overstated by the amount of the

week 39 shortage.

8.4 Week 40 (ended 31 December 2003)
8.5 Week 41 (ended 7 January 2004)

8.5.1 There are no unusual entries in these weeks.

8.6 Week 42 (ended 14 January 2004)

8.6.1 Apart from the entries for the week 39 explained at 8.3 there are no unusual

entries in this week.

8.7 Week 43 (ended 21 January 2004)
8.7.1 On 22 January 2004 a transfer of £4,230.37 to suspense account 222 is made.

8.7.2. On 20 January 2004 Mr Castleton processed two National Lottery error notices
totalling a net £1,349. These are discussed in section 10.4 and represent National
Lottery sales from 2003 that Mr Castleton had not accounted for. These have been
posted to Horizon accounts “106 POL Error Notice Receipts” and “162 POL Error
Notice Payments”.

8.7.3 The effect of the error notice was that Mr Castleton owed the Post Office £1,349. In
accordance with the terms of his contract Mr Castleton would have been required to make

good this amount.

8.7.4 From the January 2004 events report it would appear that Mr Castleton amended his cash

declaration as there are two entries as follows:

21-Jan-04 17:53:24 LCAOO1 AA DeclareCash Total £59370.87 Declaration Complete

8.7.5 The difference in these figures represents an increase in the declared cash of
£1,437.50.

8.8 Week 44 (ended 28 January 2004)

8.8.1 On 29 January 2004 a further transfer of £2,523.12 to suspense account 222 is

made.

8.8.2 The Horizon help desk log has the following message:

8.8.3. As previously discussed the first figure apparently relates to week 39.

8.9 Week 45 (ended 4 February 2004)

8.9.1 The final Horizon transaction on 4 February 2004 is a posting of £316.08 to code
145 Surplus Discrepancy (suspense). This was made by CTROO2 and I note that
all transactions that afternoon were either as CTROO1 or CTROO2. It is not clear
whether Mrs Train was using both user numbers. It is possible to use more than
one log in for example where someone is the only person in the post office and

wants to use both terminals, each of which would then have a separate code.

Week 46 (ended 11 February 2004)

The first entries on 5 February 2004 appear to relate to the National Lottery. They
consist of entries for lottery sales of £289, instant ticket sales of £12 and cash
prizes paid out of £9, a net total of £292. This is initially posted to cash but then
immediately transferred to suspense code 222.

On 12 February 2004 a further transfer of £1,513.09 to suspense account 222 is
made. On 13 February 2004 Mr Castleton makes a transfer of £8,243.10 to loss
account 223. The combined effect of these two transactions is that the system cash
will have been increased by nearly £10,000. However the £8,243.10 is reversed by

transfers out of suspense in the following week.

Week 47 (ended 18 February 2004)

The last entry on 18 February 2004 is a receipt of £7,682.60 posted to code 145
Surplus Discrepancy (suspense).

One of the first transactions on the next day, 19 February 2004, is a further receipt
of £560.50 again posted to code 145 Surplus Discrepancy (suspense).

Taken together these amounts clear the balance on the suspense account 222.

These transactions may explain why week 47 has a nil difference according to the

cash account.

Note that this does not imply that Mr Castleton has paid in over £8,000 in this

week, It simply represents a book transfer.

Week 48 (ended 25 February 2004)

There are two Horizon help desk log messages:

would question whether Mr Castleton was actually trying to move the previous
day’s transfer from suspense to the loss account. If this was the case then he
would have needed to reverse the first entry by making a posting to account 145

Surplus Discrepancy (suspense).

8.12.4. Mr Castleton received a further error notice for £862.32 relating to a cheque
transaction which is discussed in section 10.5. In accordance with the terms of his

8.12.5 From the February 2004 events report it would appear that Mr Castleton amended

9 THE ACCOUNTING RECORDS AFTER MR CASTLETON WAS
SUSPENDED

o1 The first temporary sub-postmaster

9.1.1 When Mr Castleton was suspended his line manager, Catherine Oglesby, arranged
for a temporary sub-postmaster, Ruth Simpson, to operate the Marine Drive sub-
post office. Mrs Simpson started on or about 23 March 2004 and worked there
until 21 April 2004. She had been a sub-postmistress in Hull since 1999.

9.1.2 None of Mr Castleton’s staff were permitted to work in the post office after his
suspension. Mrs Simpson operated the sub-post office with the help of one of her
staff from Hull.

9.1.3. Mrs Simpson therefore ran Marine Drive for five weeks (weeks 52 and 1 to 4).
She explains in her witness statement that she was short in three weeks and over
in the remaining two. Apart from week 1 the differences were Jess than £20. In
week 1 Mrs Simpson was short by £101.95 which she states is likely to have been

due to her assistant paying a pension twice in error.

9.2 The second temporary sub-postmaster

9.2.1 When Mrs Simpson returned to Hull she was replaced as sub-postmaster by Mr
Gregory Booth who operated Marine Drive from 21 April to 28 May 2004, a

further five weeks.

9.2.2 Mr Booth states that in weeks 5 to 9 he was between £14.26 over and £6.63 short

on his cash account.

9.3 Conclusions

9.3.1 I would have expected that if there were computer problems affecting the
accounting system that they would have continued in the weeks after Mr Castleton

was suspended. There is no indication that this has happened.

OTHER POSSIBLE REASONS FOR ERRORS
Introduction

I have considered the areas of the accounting system that could have resulted in
losses of the size reported at Marine Drive. The weekly “cash account” that was
produced when Mr Castleton was at Marine Drive is a form of trial balance as it
includes as well as cash also stock, cheques, and banking and investment
movements. It is not a complete conventional accounting trial balance as the Post
Office does not identify sales of stock items. Sales of stamps, for example, are
deducted from the stock of stamps. This may reflect that no profit I made by the
sub-postmaster on these transactions and that the system adopted should assist in

the reconciliation of stock.

The Marine Drive records

I have looked at the possibility that there might be a difference in the cheques
received at Marine Drive. I have examined the transactions for Horizon code 2
cheques for January and February and in both months the total of cheques

received is matched by cheques sent to the processing centre.

The movements in the stocks of stamps, postal orders etc do not appear to be large

enough to cause significant differences.

My conclusion is that any differences within Marine Drive are likely to be within

the cash account or in items associated with it.

employees responsible for various aspects of the accounting system. These
include individuals who are involved in checking those transactions which
generate documents that are sent by the sub-postmaster to a central clearing
centre, for example social security giros that have been cashed. From time to time
sub-postmasters make mistakes and where these result in a loss then the amount
has to be repaid. Where the error is the sub-postmaster’s favour then he or she is
given credit for the amount. The Post Office operates a system of Error Notices
which explain the problem to allow the sub-postmaster to investigate and then if
necessary make good the error by paying in cash (or alternatively removing the

amount of any surplus).

There are two occasions in the period that I have reviewed when Mr Castleton
was sent error notices as shown on page 2 of appendix 2. These were entered by
Mr Castleton in Horizon in weeks 43 and 48. However they relate to mistakes that
took place many months earlier. I have examined how Mr Castleton has dealt with

these.

National Lottery

Michael Johnson is employed as a postal officer in the Lottery Exceptions team.
His witness statement deals with the procedures for checking National Lottery
transactions. Mr Johnson explains that ten errors have arisen since Mr Castleton
was appointed as sub-postmaster. The errors all arose before the period I am
reviewing but three of them were dealt with in an error notice dated 16 January
2004, totalling £1,414 credit with a further £65 debit which is adjusted in the same
week 43, The £1,414 is described as a charge error and Mr Johnson explains that
this could arise if the sub-postmaster sold a lottery ticket but failed to enter the
details of the transaction on to their Horizon computer system. The £65 is
described as a charge error and the example given is where a sub-postmaster

enters a lottery sale twice on Horizon.

10.5.1

10.5.2

Given that National Lottery transactions have to be entered twice, once through
the Camelot terminal and then through Horizon the possibility for mistakes exists.
A further complication is that the Marine Drive lottery terminal is actually in the
shop rather than the post office, I assume that lottery purchases would initially be

put through Mr Castleton’s shop till(s) with a further possibility for error.

The National Lottery error notice was posted to Horizon by Mr Castleton on 20
January 2004. I note from page 1 of appendix 4 that the variance between Mr
Castleton’s cash declarations and the cumulative balance increases from £3,882
on 19 January to £5,235 on 20 January. It would appear that the £1,349 has not
been repaid by Mr Castleton and it would seem that this is part of the £4,230.97
transferred to suspense on 22 January which is included in the Post Office claim

as shown in appendix 1.

Cheque transactions

Gillian Hoyland is employed as a postal officer in the Cheques to Processing
team. Her witness statement deals with the procedures for checking when
customers pay for a product or service by cheque (for example they purchase a
television licence and pay with a cheque). Gillian Hoyland explains that the only
error arising in the period I am reviewing was an error notice dated 12 February
2004 for £862.32 which goes back to a discrepancy that occurred in the cash
account week 17 September 2003.

This is included as an adjustment to receipts in the cash account on 25 February
2004 (week 48). This entry to nominal account 106 takes place at 18.29 when Mr
Castleton is doing his end of week reports. The effect of posting an error notice is
that the amount Mr Castleton need in cash to balance would have increased by
£862.32. The declared cash figures before and after the transaction taken from the
February events spreadsheet remained at £36,226.05. The final cash figure
declared by Mr Castleton early the next morning was £36,598.05.
