Chairman's Statement

I am delighted to report another excellent performance - our 15th successive
year of strong and profitable growth. Sales were up 16.2% and pre-tax profits
rose 26.3% before goodwill, maintaining our record of consistently high growth.
In delivering this growth we have continued to convert a high proportion of
profits into cash while funding the working capital required to bid
successfully and implement new business activities and contracts. This is a
very satisfying result for a year that proved unsettling for the support
services sector in the UK.

Our vigorous organic growth reflects Serco's key strengths: our long-term
contract base, ability to enhance customers' operations continuously, and long
experience of delivering outsourced public services across a wide range of
markets. We have a well-diversified portfolio, rigorous risk management
processes integrated with the way we do business, and a selective approach to
bidding.

Contract wins during the year totalled �1.2bn. We won 122 new contracts,
achieving our target of winning over half of new bids. In addition, we were
awarded 180 rebids or extensions to existing contracts, maintaining our success
rate of over 90% in this area.

Financial performance

Turnover grew 16.2% to �1.3bn. Pre-tax profits were up 26.3% to �57m before
goodwill amortisation and by 22.2% to �48.9m after goodwill amortisation. There
were no exceptional items in 2002.

Earnings per share rose 16.1% to 9.58p before goodwill and 10.4% to 7.66p after
goodwill.

Cash generation remains robust with 75.1% of group EBITDA converted into cash.

We raised �117.4m through an international placing of new shares in March. This
was partly to refinance the September 2001 acquisition of AEA Technology's
nuclear consulting business - now successfully integrated into Serco Assurance
- and partly to strengthen the Balance Sheet to facilitate future growth. Since
flotation in 1988 Serco has raised new equity totalling �161m, less than our
acquisition costs of �180m over the same period. Apart from this, we have
funded our growth from under �50m to over �1.3bn annual sales entirely from
internally-generated cash flow.

More sophisticated forms of contract inevitably mean more complex financial
statements. In response, we have introduced Financial Review sections to our
annual and interim results announcements and continue to extend our commentary
on relevant aspects of accounting and corporate governance. To help investors
understand better our Private Finance Initiative (PFI) projects we have also
published Our approach to PFIs. The latest edition, updated in September 2002,
is available on our website at www.serco.com or on request.

Dividend

The recommended final dividend of 1.44p per share gives a cumulative dividend
for the year of 2.08p - an increase of 11.8% over 2001. It is proposed that the
dividend will be paid on 13 May 2003 to shareholders on the register on 28
February 2003 (record date).

Pensions

The recent poor performance of the equity markets has impacted the group's
defined benefit pension schemes. A valuation at 31 December 2002 has identified
a net deficit of �73.6m in accordance with

FRS 17 on our defined benefit schemes. This will result in additional funding
and an additional profit and loss charge of �9m per annum. Notwithstanding this
increase in contributions we remain on course to achieve good growth going
forward.

Chairman's Statement

Operational performance

Our business is made up of five distinct areas: defence (which accounted for
27% of 2002 sales), transport (27%), civil government (27%), science (9%) and
private sector clients (10%). Within these sectors, revenues from PFI contracts
accounted for 12% of total sales.

The year was characterised by strong organic growth built on solid foundations:
a track record of effectiveness that attracts and convinces new customers,
strategic alliances with partners who enhance our capability and credibility,
and an approach to working with customers that encourages partnerships,
extensions and broadening of relationships. As in the past, a significant part
of our turnover growth has come from add-ons and extensions to existing
contracts.

Major contract awards in 2002 included an innovative partnership with the UK's
Ministry of Defence (MOD) Warship Support Agency to manage the Devonport,
Portsmouth and Clyde marine services contract. This three-year partnership,
worth up to �110m, builds on an earlier contract we have had since 1996. We
also won a partnership contract to provide communications and information
technology services to the Defence Scientific and Technical Laboratory, worth
some �10m annually for up to eight years.

As a member of the Paradigm Secure Communications team, which was selected in
February 2002 as preferred bidder to provide and operate Skynet 5 global
military satellite communications services, Serco will be providing network and
facilities management. This is the largest UK MOD PFI to date, potentially
worth some �220m to Serco over 15 years, and good progress continues to be made
towards contract signature.

As in any year there were a few disappointments - principally our unsuccessful
bid to manage the Army Training Estate and Essex County Council's decision not
to pursue the outsourcing of educational services. But disappointment over the
Essex decision was tempered by continuing growth for our education business in
Walsall: the local council transferred a further 300 staff to us, tripling the
value of our contract to �100m over the remaining 5� years. This followed a
very favourable review of our performance by Ofsted, the education regulator,
which led to a decision to transfer the majority of Walsall's Local Education
Authority's activities to Serco.

This was one of many cases where strong performance was rewarded with
substantial contract extensions. Others included the National Crime Squad,
which more than doubled the size of our partnership contract to support its IT
operations and to design and develop its Intelligence Management System. In the
US, the Federal Aviation Administration significantly broadened our role: we
are already one of its largest private providers of air traffic control
services, and it has now awarded us a contract to provide weather observation
services.

The largest addition of all - indeed, the largest contract ever awarded to the
group - was announced in January this year, a 15-year extension to the contract
under which we manage the UK's Atomic Weapons Establishment (AWE) in
partnership with Lockheed Martin and British Nuclear Fuels (BNFL). The contract
will now run until 2025, adding over �1bn to our forward order book.

Our stature as a light rail operator continues to grow. For an unprecedented
second year running we won the UK Rail Operator of the Year award, recognising
our operational excellence and innovative customer service on London's
Docklands Light Railway (DLR). We intend to build on our achievements with the
DLR, Manchester Metrolink and Copenhagen Metro by selectively addressing
additional rail operating opportunities. We have formed a joint venture with
NedRailways, the international arm of Dutch national rail operator Nederlandse
Spoorwegen, to pursue some of these.

In the UK our strategy is to build on our contract base and to expand into new
areas. While continuing to grow in our traditional markets, we seek out
contracts that require greater managerial or technological sophistication, with
structures that focus on outputs rather than specified inputs. We continue to
bid for selected PFIs and expect our PFI projects to deliver sustained
long-term benefits both to the public and to our investors. They and their
associated service contracts will provide an income stream to supplement our
revenues from traditional contracts. Under the auspices of the Confederation of
British Industry (CBI) public services strategy board, we have joined other
public service providers in a programme to promote better understanding of the
benefits of public private partnerships. This aims to stress their importance
and effectiveness in obtaining value for money and diversity in public service
delivery.

Chairman's Statement

Our commitment to international diversification - with 30% of our current
business turnover overseas - is one of the factors that differentiates us in
our sector. But the sheer scale of opportunities open to us in the UK means
that we have to be selective. In Europe we see particular opportunities in
Italy and Germany, and are making encouraging progress in both. In the Middle
East our activities and profile continue to develop well. In Asia Pacific we
are focusing principally on Australia and New Zealand, where state governments
continue to develop policies on public private partnerships. In North America
we see public private partnerships emerging in both the US and Canada: these
countries potentially represent a major long-term market for our skills and
experience.

To concentrate management and financial resources on the most promising
opportunities and markets at home and abroad, we continue to review our
business portfolio. This enables us to sharpen our focus on contracts offering
superior growth, margins and cash generation, and may lead to minor divestments
of certain activities.

Risk management

One of the keys to Serco's consistently robust performance is its management
system and control framework. Our operations are diversified across some 600
contracts and a range of business sectors. Few contracts represent more than 2%
of our turnover and the largest represents only 7%.

The high degree of autonomy that we give to our contract managers is balanced
by rigorous monitoring and unobtrusive but effective controls. In 2001 we set
up our Corporate Assurance Group (CAG) to integrate our approach to assessing
business risks and improving controls, and to ensure that we safeguard the
interests of shareholders, customers, staff and the wider community. Reporting
directly to the Board, CAG is proving a valuable asset in risk management.

Corporate social responsibility

Although Serco is a private sector business, we earn our living predominantly
by delivering public services. We need to demonstrate a public service ethos,
as a prerequisite of our partnership with public sector customers.

We take our corporate social responsibility (CSR) seriously. Under our
corporate governance framework every contract manager is directly accountable
for CSR performance. We have established a global network of CSR champions to
raise general awareness and support initiatives that range from developing an
alternative water supply for Goose Bay residents in Canada to collecting tonnes
of stationery for schools and orphanages in Kabul. We continue to refine our
approach and are currently developing a new structure for charitable giving.
This is designed to support initiatives by our contracts and individual
employees, direct resources towards the communities where we work and recognise
the personal commitment of Serco people.

People

Serco's continuing success comes from the outstanding dedication of our people
and their personal identification with what they do. In a MORI survey of a
cross section of staff, 95% regarded their work as `more than just a job'.
Other positive indications - given our drive for continuous improvement and
evolution to meet customer needs - were that around three quarters said they
understood workplace objectives and the need for change, and two thirds
actively supported the change process. We are grateful for all our people's
energy, enthusiasm and imagination - which add value both to our business and
to our customers' operations.

We continue to build constructive relationships with trade unions. In the UK we
support the Partnership Institute launched by the Trades Union Congress (TUC)
to foster co-operative relationships between employers and unions. We have
formed a number of `working partnerships' with unions at contract level and are
investigating further opportunities.

To support and sustain our growth, we attach great importance to training and
developing our managers. During the year the Serco Best Practice Centre
provided courses and workshops in the UK, Europe, North America and the Middle
East, and our global intranet played an important role by giving people access
to training and development online. In a ground-breaking partnership with the
UK's Institute of Directors (IoD) we have developed a joint IoD/Serco
Certificate in Company Direction assessed and recognised by the IoD. The first
19 Serco managers were awarded the qualification during the year.

Chairman's Statement

Outlook

The committed future income streams from our contracts give us the assurance of
highly visible revenues and profits. At the time of writing we have already
secured 91% of our planned revenue for 2003 and 80% of our planned revenue for
2004.

Our forward order book continues to grow. On 31 December it stood at �6.1bn,
and it now stands at �7.1bn - roughly 5.5 times last year's turnover. We are
currently addressing over �12bn of opportunities and our markets are buoyant.
Both at home and abroad, opportunities are emerging at a rate which continues
to allow us to bid selectively.

Our portfolio approach to a wide range of public sector markets has provided a
strong growth platform during this period of difficult global economic
conditions. We remain confident of achieving double-digit growth both this year
and over the longer term.

1.1 Turnover

Total turnover increased by 16.2% to �1,325.9m. This includes a contribution of
�43.3m (2001: �12.1m) from Serco Assurance (formerly the nuclear consulting
division of AEA Technology), which was acquired in September 2001.

1.2 Gross profit

Gross profit of �150.0m increased by 20.9% and represents a return on group
turnover of 13.7% (2001: 13.6%).

1.3 Pre tax profit

Pre tax profit before goodwill amortisation increased 26.3% to �57m.

1.4 Underlying pre tax profit

There were no exceptional items in 2002. In order to allow comparison of the
year on year results the growth in underlying pre tax profit is shown below:

Underlying pre tax profit grew 20.1% to �54.9m. Underlying profits are stated
after:

- a �2.1m (2001: �0.5m) contribution from Serco Assurance,

- a prior year adjustment of �1.2m in 2001 made on the adoption of UITF
Abstract 34 in 2002; this is explained in greater detail in `Bid costs', and

- a net contribution in 2001 of �0.2m from three one-off items.

1.5 Tax

The tax charge for 2002 was �16.6m (2001: �13.0m), representing an effective
tax rate of 34.0% (2001: 32.5%). The increase in the effective rate is largely
as a result of an increased year-on-year level of goodwill amortisation.

1.6 Earnings per share

Taking into account the above and the increased capital base resulting from the
equity placing in March, earnings per share before goodwill amortisation grew
by 16.1% to 9.58p.

2 DIVIDENDS

The proposed final dividend of 1.44p per share gives a cumulative dividend for
2002 of 2.08p, an 11.8% increase on 2001.

3 SHARE PLACEMENT

In March �117.4m (net of fees) was successfully raised through an international
bookbuilt placing of 39.5m new shares representing 9.9% of Serco's issued share
capital. This enabled the Serco Assurance acquisition finance to be repaid and
the Balance Sheet to be strengthened to facilitate future growth.

Since flotation in 1988 Serco has raised new equity totalling �161m, roughly
equivalent to our acquisition costs of �180m over the same period. Apart from
this, we have funded our growth from under �50m to over �1.3bn of annual sales
entirely from internally generated resources.

4 CASH FLOW

During the year there was a net cash inflow of �105.2m. This inflow was after a
one-off payment of �15.5m into the Serco Pension & Life Assurance Scheme in
February and includes �117.4m from a share placing in March. This cash inflow
contributed to the reduction in Group net debt/funds, excluding non-recourse
PFI debt, from �(93.5)m to �6.3m respectively, as detailed below:

Recourse net cash/(debt)                                    6.3    (93.5)

4.1 Operating cash flow before one-off items

Operating cash flow, before one-off items, was up 54% to �39.6m (2001: �25.7m),
which converts 136% (2001: 121%) of our operating profit into cash.

We believe that, as operating profit is calculated after deducting goodwill and
depreciation, the appropriate measure for operating cash flow performance is
the conversion of Group EBITDA (Earnings Before Interest, Tax, Depreciation and
Goodwill Amortisation) before one-off items into operating cash flows. For 2002
this was 75.1% (2001: 64.9%).

The working capital movement reflects the strong level of organic growth shown
by the Group in 2002 and equates to approximately one months incremental
turnover, reflecting the typical invoicing cycle of our contracts.

4.2 Joint ventures

Serco has two types of joint ventures: those which represent traditional
operating contracts, such as the Atomic Weapons Establishment (AWE) and Premier
Custodial Group (PCG); and those reflecting Serco's equity stakes of up to 50%
in PFI Special Purpose Companies (SPCs).

Dividends received from joint ventures during 2002 of �11.1m (2001: �9.6m)
represents a 67% (2001: 76%) conversion of profit of joint ventures, after tax,
into cash.

Financial Review

For the year ended 31 December 2002

4.3 Capital expenditure

Capital expenditure, excluding investment in PFI SPCs, for the year was �23.6m
(2001: �17.6m). As a proportion of Group turnover this expenditure represents
2% and has remained at a similar level to previous years.

4.4 Net debt

In addition to the recourse debt shown in the table above, the Group has a
non-recourse loan to fund the construction of the Traffic Control Centre (see
PFIs below). At the end of 2002 this loan was �29.7m (2001 �14.1m).
Non-recourse debt is excluded from the Group's banking facility covenants but
is presented as a liability in the Group's Balance Sheet.

5 PENSIONS

In 2002, two of Serco's pension schemes were accounted for as defined benefit
schemes.

The total 2002 pension charge for Serco was �29.1m (2001: �19.5m), with the two
UK defined benefit schemes having a cost of �12.5m (2001: �9.3m).

FRS 17 "Retirement Benefits" was issued in November 2000 to replace SSAP 24 for
accounting periods ending on or after 22 June 2003. In July 2002 the Accounting
Standards Board delayed the introduction of FRS 17 until 2005, following an
announcement by the International Accounting Standards Board that it would also
issue a new standard.

For 2002 we have continued to apply the transitional rules and disclosures. FRS
17 requires the market value of assets and liabilities for defined benefit
schemes to be calculated and included in the Balance Sheet. At 31 December 2002
we estimate there was a net deficit of �73.6m in relation to the defined
benefit schemes and an asset base of approximately �294.4m, whilst the Minimum
Funding Rate (MFR) funding level was 100%. Long term company contribution rates
will increase by approximately �9m per annum from 2003.

In February 2003 we merged Serco's two defined benefit pension schemes to
achieve cost and investment efficiencies. To assist this process �15.5m was
injected into the Serco Pension and Life Assurance Scheme in February 2002 to
achieve a similar funding level for both schemes. The investment profile of the
merged scheme will be kept under continuous review to match the asset and
liability profiles.

6 PRIVATE FINANCE INITIATIVES (PFIs)

6.1 Disclosure

The document `Our Approach to PFIs', which was originally issued in 2001, was
updated in September 2002 and provides a summary of our accounting for PFIs. It
is available on our website www.serco.com or in printed form on request.

6.2 PFI Profile

For 2002 PFIs contributed �154.0m to turnover and �17.7m to profit before tax
for the year, of which �110.4m of the turnover and �6.4m of the profit related
to the operating contracts, and �43.6m of the turnover and �11.3m of the profit
to Serco's share of the SPCs.

Financial Review

For the year ended 31 December 2002

6.3 SPC funding

SPC funding is via long term loans which are non-recourse to Serco.

- Our share of non-recourse debt of joint venture SPCs at the end of 2002 is �
206.7m. This is included as a liability within investments in joint ventures on
our Balance Sheet.

- Traffic Information Services (TIS) Limited is the first SPC where Serco has
chosen to own 100% of the equity. This SPC has the contract to deliver the
Traffic Control Centre (TCC) contract. A non-recourse loan of �29.7m to fund
the asset, currently in the course of construction, is included in long term
creditors in the Balance Sheet. Construction completion is anticipated in early
2004 when the non-recourse loan will equate to approximately �60m.

- In June 2002 the lenders to the Joint Services Command and Staff College
(JSCSC) PFI agreed to change the terms of the senior debt. This transaction had
no effect on profit but allowed �6.7m of cash to be paid from the SPC to Serco
by way of dividend and loan.

7 REVIEW OF JOINT VENTURE ACCOUNTING AND CONTROLS

In March 2002, in recognition of the perceived uncertainties arising from
certain joint venture accounting practices in the US, the Board undertook a
specific review, including asking Deloitte & Touche to undertake an independent
review of our accounting procedures and internal controls over our joint
ventures. This review confirms the Board's view that all our joint ventures
exist for genuine commercial reasons, are correctly accounted for and that our
controls and disclosures are appropriate.

8 BID COSTS

Urgent Issues Task Force (UITF) Abstract 34 " Pre-contract costs" was issued in
May 2002 for accounting periods ending on or after 22 June 2002. UITF Abstract
34 requires all bid costs to be expensed up to the point where award of a
contract is `virtually certain'. Bid costs incurred after this point may be
capitalised. At 31 December 2001 we had �1.2m of bid costs capitalised in
relation to contracts for which we had not reached preferred bidder status.
Applying the Abstract has resulted in a small prior year adjustment to treat
these capitalised costs as expensed in 2001. Having made this adjustment our
accounting policies now fully comply with UITF Abstract 34.

9 DEFERRED TAXATION

Financial Reporting Standard (FRS) 19 `Deferred Taxation' was issued in
December 2000 for accounting periods ended on or after 23 January 2002. FRS 19
requires full provision to be made for deferred tax assets and liabilities
arising from timing differences between the recognition of gains and losses in
the financial statements and their recognition in a tax computation.

The tax charge for the year has been calculated in accordance with FRS 19. The
adoption of FRS 19 has not had a material effect on the tax charge, as the
Group did not have a material level of unprovided deferred tax liabilities or
unrecognised deferred tax assets.

10 TREASURY POLICIES

10.1 Treasury management

The Group's tax and treasury function is responsible for managing the Group's
exposure to financial risk. It operates within policies approved and reviewed
by the Board, which include controls on the use of financial instruments. The
Group reviews the credit quality of counterparties and limits individual
aggregate credit exposures accordingly.

Financial Review

For the year ended 31 December 2002

10.2 Liquidity management

The Group funds its operations through bilateral bank credit facilities and a
long term US Private Placement of loan notes (`the US Notes'). Borrowings under
the bank facilities are floating rate, unsecured, obligations with covenants
and obligations typical of these type of arrangements.

At the end of 2002 bank facilities totalled �161m, of which �50m was committed
funding and of which �151m was undrawn. The committed bank facilities mature in
November 2005. The US Notes mature in December 2007.

10.3 Foreign exchange risk

Due to the nature of the Group's business, which in general does not involve a
significant amount of cross-border trade, the Group is not exposed to material
foreign currency transaction risk, as sales and costs are approximately matched
within overseas operations.

The Group does not hedge the sterling equivalent of the net assets of its
overseas operations on the grounds that the market value of these businesses
does not represent a significant proportion of the market value of the Group
and because foreign exchange differences are unlikely to have a material effect
on the consolidated net asset value of the Group.

The US Notes were issued in US Dollars but the principal obligation has been
swapped into sterling consistent with the risk profile set out above.

10.4 Interest rate risk

The Group's exposure to interest rate fluctuations on its borrowings and
deposits is selectively managed, using interest rate swaps. The element of the
US Notes that has not been swapped into floating rates is considered to offer
adequate protection from interest rate fluctuations in the current market and
given the Group's current low level of net debt. All shorter term debt is
maintained at floating rates of interest.

Notes to the Preliminary Announcement

For the year ended 31 December 2002

1 Accounting policies

This preliminary announcement has been prepared in accordance with applicable
UK accounting standards, and the particular accounting policies adopted are
detailed below. These have all been applied consistently with the exception of
bid costs which is explained in the restatement below.

Accounting convention

This preliminary announcement has been prepared under the historical cost
convention.

Basis of consolidation

The preliminary announcement consolidates the financial information of the
Company and its subsidiaries, and equity accounts for its share of joint
ventures made up to 31 December of each year, for the periods they are owned by
Serco Group plc.

Restatement

The 2001 financial information has been restated to reflect the impact of the
Urgent Issues Task Force Abstract 34 ("UITF34") - Pre-Contract Costs;
eliminating �1,193,000 of bid costs, previously disclosed within debtors, and
the associated tax effect of �387,000. The impact of this adjustment in the
2002 financial information is a reduction in amortisation of bid costs of �
400,000.

The Profit and Loss Account has been restated to reclassify `Other operating
costs relating to joint ventures' within `Other administrative expenses'.

Accounting for PFI Contracts

Within Public Private Partnership (PPP) projects (including Private Finance
Initiative (PFI) projects), where the concession agreement transfers limited
risks and rewards associated with ownership to the contractor, the costs
incurred during the period of initial asset construction, as a direct
consequence of financing, designing and constructing the asset, are shown as
"assets in the course of construction" within current assets. On completion of
the asset construction phase the asset is transferred to debtors as "amounts
receivable under PPP contracts".

Revenues received from the customer are apportioned between capital repayments
and operating revenue. The `finance income' element of the capital repayment is
shown within interest receivable.

Serco has one Special Purpose Company - TCC (Traffic Control Centre), where the
results are fully consolidated. All other SPCs are classified as joint ventures
and accounted for using the gross equity method.

Pension costs: Defined benefit schemes

Retirement benefits to employees of Group companies, except in Germany, are
funded by contributions from Group companies and employees. Payments are made
to trust funds which are financially separate from the Group in accordance with
periodic calculations by consulting actuaries. The expected cost to the Group
of providing defined benefit pensions is charged to the Profit and Loss Account
so as to spread the cost of pensions over the average service lives of
employees in the schemes, in such a way that the cost is a substantially level
percentage of payroll cost, with experience surpluses and deficits being
amortised on a straight line basis.

In Germany retirement benefits to employees are accrued for by Serco GmbH & Co.
KG. The expected cost to the Company for providing defined benefit pensions is
calculated in accordance with periodic valuations by consulting actuaries.

Pension costs: Defined contribution schemes

Contributions for the year in respect of defined contribution schemes are
charged to the Profit and Loss Account. Differences between charges accruing
during the year and cash payments are included as either accruals or
prepayments in the Balance Sheet.

The Group has adopted the transitional disclosure requirements of Financial
Reporting Standard 17 ("FRS17") - Retirement Benefits. For further information
see Note 31.

Turnover

Turnover represents net sales of goods and services to third parties together
with investment related income.

Goodwill

Goodwill arising on acquisitions is capitalised in the Consolidated Balance
Sheet in accordance with Financial Reporting Standard 10 ("FRS 10") - Goodwill
and Intangible Assets. Amortisation of goodwill is provided on a straight line
basis over a period of 20 years, which, in the opinion of the Directors is a
period not exceeding the economic useful life of the asset.

Notes to the Preliminary Announcement

For the year ended 31 December 2002

1 Accounting policies (continued)

Current Tax

Current tax, including UK Corporation Tax and foreign tax, is provided at
amounts expected to be paid (or recovered) using the tax rates and laws that
have been enacted or substantially enacted at the Balance Sheet date.

Fixed asset investments: Subsidiaries

Investments held as fixed assets are stated at cost less provision for any
impairment in value.

Fixed asset investments: Joint ventures

In the consolidated preliminary announcement, investments in joint ventures are
accounted for using the gross equity method of accounting in accordance with
Financial Reporting Standard 9 ("FRS 9") - Associates and Joint Ventures.

The Group Consolidated Profit and Loss Account includes the Group's share of
joint ventures' operating profits and interest, and the attributable taxation.
In the Consolidated Balance Sheet, the Group's share of the net assets of its
joint ventures, which includes several PFIs, is included under the heading
"investments in joint ventures". The share of net assets is split between gross
assets and gross liabilities.

Fixed asset investment: Own shares

Investment in own shares represents shares in Serco Group plc held by the Serco
Group plc 1998 Employee Share Ownership Trust ("the Trust"). The dividends on
these shares have been waived. Investment in own shares is stated at cost less
provision for impairment.

The Trust is a discretionary trust for the benefit of the employees and shares
are held to satisfy the Group's liabilities to employees for share options and
long term incentive plans. The net cost to the Group of these schemes is
charged to the Profit and Loss Account over the performance period during which
the benefits are earned by employees.

Leases

Assets obtained under finance leases are capitalised at their fair value on
acquisition and depreciated over the shorter of their estimated useful lives or
lease term. The finance charges are allocated over the period of the lease in
proportion to the capital element outstanding. Rentals on assets under
operating leases are charged to the Profit and Loss Account in equal annual
amounts.

Depreciation

Depreciation is provided on a straight line basis at rates which, in the
opinion of the Directors, reduce the assets to their residual value over their
estimated useful lives.

The principal annual rates used are:

Freehold buildings                2.5%                                       
                                                                             
Short leasehold building          The higher of 10% or rate produced by lease
improvements                      term                                       
                                                                             
Machinery                         15% - 20%                                  
                                                                             
Motor vehicles                    18% - 50%                                  
                                                                             
Furniture                         10%                                        
                                                                             
Office equipment                  20% - 33%                                  
                                                                             
Leased equipment                  The higher of the rate produced by either  
                                  lease term or useful life                  

Stocks

Stocks are stated at the lower of cost and net realisable value. Cost includes
an appropriate proportion of direct material and labour.

Long term contracts

Long term contract balances represent costs incurred on specific contracts, net
of amounts transferred to cost of sales in respect of work recorded as turnover
by reference to the value of the work carried out to date. No profit is
recognised until the contract has advanced to a stage where the total profit
can be assessed with reasonable certainty. Advance payments are included in
creditors to the extent that they exceed the related work in progress.

Pre-contract costs

All bid costs are expensed through the Profit and Loss Account up to the point
where contract award is virtually certain in accordance with UITF 34. Bid costs
incurred after this point are then capitalised within debtors. On contract
award these bid costs are amortised through the Profit and Loss Account on a
straight line basis over the contract period.

Notes to the Preliminary Announcement

For the year ended 31 December 2002

1 Accounting policies (continued)

Deferred taxation

The charge for taxation takes account of taxation deferred because of
differences between the timing of recognition of certain items for taxation
purposes and for accounting purposes. Deferred tax is recognised in respect of
all timing differences that have originated but not reversed at the Balance
Sheet date where the transactions or events that give rise to an obligation to
pay more or less tax in the future have occurred by the Balance Sheet date. A
deferred tax asset is recognised only when it is considered more likely than
not that it will be recovered.

Deferred tax is recognised on a non-discounted basis using tax rates in force
at the Balance Sheet date. Financial Reporting Standard 19 ("FRS 19") -
Deferred Tax has been adopted for the first time in this preliminary
announcement and there is no material effect on the comparative figures.

Basis of translation of foreign currencies

Transactions of UK companies denominated in foreign currencies are translated
into Sterling at the rate ruling at the date of the transaction. Amounts
receivable and payable in foreign currencies at the Balance Sheet date are
translated at the rates ruling at that date and any differences arising are
taken to the Profit and Loss Account.

The financial information of overseas subsidiary companies and associated
undertakings is translated into Sterling at the closing rates of exchange at
the Balance Sheet date and any difference arising from the translation of the
opening net investment and matched long term foreign currency borrowings is
taken directly to reserves. The Profit and Loss Account is translated using
average exchange rates.

9 Earnings per Ordinary Share

Basic and diluted earnings per Ordinary Share after goodwill have been
calculated in accordance with Financial Reporting Standard 14 - Earnings Per
Share. Earnings per share is shown both before and after goodwill to assist in
the understanding of the impact of FRS 10 on the preliminary announcement.

The calculation of basic earnings per Ordinary Share after goodwill is based on
profits of �32,302,000 for the year ended 31 December 2002 (2001 restated - �
27,027,000) and the weighted average number of 421,813,107 (2001 - 389,552,980)
Ordinary Shares of 2p each in issue during the year.

The calculation of basic earnings per Ordinary Share before goodwill is based

Notes to the Preliminary Announcement

For the year ended 31 December 2002

17 Treasury policies and risk management

The principal risks arising from the Group's financing activities are interest
rate risk and foreign currency risk. Treasury operations are conducted within a
framework of policies set and reviewed by the Board. There has been no material
change during the year or since the year end to the major financial risks faced
by the Group or the Group's approach to the management of these risks.

As permitted by Financial Reporting Standard 13 - "Derivatives and other
Financial Instruments: Disclosures" short term debtors and non interest bearing
short term creditors and loans from joint ventures have been excluded from the
following disclosures other than the disclosure of the currency profile of
financial assets and liabilities.

The fundamental purpose of interest rate and foreign currency financial
instruments entered into is to hedge monetary assets and liabilities, the
details of which are set out below.

Interest rate risk

The Group borrows at both fixed and floating rates of interest. The Group's
exposure to interest rate fluctuations on its long term borrowings is managed
by using interest rate swaps and forward rate agreements. At 31 December 2002,
after taking account of interest rate swaps, the proportion of the Group's
fixed rate borrowings was 66.6% (2001 - 33.3%).

Foreign currency risk

The Group's policy is not to hedge the net assets of overseas subsidiaries as
they represent a small proportion of the market value of the Group and because
exchange rate fluctuations thereon are unlikely to have a material effect on
the consolidated net asset value of the Group.

Business units are required to hedge their material trading transactions (sales
and purchases in currencies other than their functional currency) by using
forward contracts. There were no material debtors or creditors as at 31
December 2002 with unhedged transactional exposure.

Foreign currency assets which are hedged using forward foreign exchange
contracts are translated at the contracted rates. The fair value of other
foreign currency contracts, interest rate swaps, and the US$70,000,000 loan
notes, have been determined by reference to prices available from the markets
on which the instruments involved are traded.

Gains and losses on hedges

Changes in the fair value of financial instruments used as hedges are not
recognised until the hedged position matures. There was an unrecognised gain of
�1,716,000 (2001 - gain of �4,492,000) on hedges as at 31 December 2002. The
unrecognised gain is not expected to be recognised in the Profit and Loss
account in the next period.

Borrowing facilities

The Group had committed bank credit facilities of �50,000,000 at 31 December
2002. The Group also had annually renewable uncommitted bank facilities
totalling �111,000,000, all of which were undrawn at 31 December 2002.

Notes to the Preliminary Announcement

For the year ended 31 December 2002

31 Pension schemes

The Group has continued to account for pensions in accordance with SSAP 24.
Full adoption of the requirements of FRS 17 `Retirement Benefits' will not be
mandatory for the Group until the year ended 31 December 2005. The transitional
disclosures required by FRS 17 are set out in Part (B) of this note which shows
the Group's pension deficit in accordance with FRS 17 at 31 December 2002 was �
73.6 million (2001 - �3.6 million) on an asset base of �294.4 million (2001 - �
298.4 million).

(A) SSAP 24 Disclosure

The net pension charge in accordance with SSAP 24 for the year ended 31
December 2002 was �29,096,000 (2001 - �19,544,000). The Group operates or is a
member of a number of pension schemes as follows:

a) Serco Pension and Life Assurance Scheme ("SPLAS")

This is a pre-funded defined benefit scheme.

The funding policy is to contribute such variable amounts, on the advice of the
actuary, as will achieve 100% funding on a projected salary basis.

The latest formal valuation of the scheme was carried out as at 6 April 1999.
The figures included in the accounts are based on a formal valuation, which is
currently being carried out as at 6 April 2002. During 2002 there has been a
fall in general stock market values and a bulk transfer was received from the
AEA Technology Pension Scheme. The figures in the Profit and Loss Account and
the Balance Sheet prepayment have been determined in accordance with the
requirements of SSAP 24. The average contribution rate is currently 18% for the
scheme.

The projected unit method was adopted for the actuarial valuation of the Scheme
for accounting purposes. The main actuarial assumptions used to value
liabilities are:

Investment yield          7.0% p.a. (5.5% post retirement)              
                                                                        
Salary growth             3.75% p.a.                                    
                                                                        
Price inflation           2.5% p.a.                                     
                                                                        
Pension increases         2.5% p.a.                                     

The Scheme is assessed to be fully funded on a current funding level basis
based on a market value of assets of �145,881,000 at 6 April 1999. Liabilities
for this purpose are calculated using the basis for determining individual cash
equivalents for active members and deferred pensioners and by estimating the
cost of purchasing annuity policies for pensioners.

The actuarial value of the assets represented 81% of the ongoing liabilities of
the Scheme. Variations from the normal costs are amortised for accounting
purposes over a fifteen year period as a constant monetary amount.

Employer pension contributions paid into the Scheme during the year were �
12,300,000 (2001 - �9,760,000), of which �500,000 related to special
contributions in respect of a discretionary increase to pensions in payment
awarded during the year (2001 - �652,000) and �600,000 of contributions in
respect of augmentations (2001 - �810,000). A �15,000,000 contribution which
was included in accruals and prepayments at 31 December 2001 was paid in
February 2002.

At 31 December 2002 a prepayment of �17,450,000 (2001 - �17,360,000) in respect
of the Scheme was included in the Balance Sheet. �12,210,000 was charged to the
Profit and Loss Account in respect of the Scheme (2001 - �8,950,000).

b) The Serco-IAL Pension Scheme

This is a pre-funded defined benefit scheme.

The funding policy is to contribute such variable amounts, on the advice of the
actuary, as will achieve 100% funding on a projected salary basis.

Notes to the Preliminary Announcement

For the year ended 31 December 2002

31 Pension schemes (continued)

Actuarial assessments covering expenses and contributions are carried out by
independent qualified actuaries, with the last such review being carried out as
at 31 March 2001. On the assumptions adopted for accounting purposes and based
on a market value of assets of �104,037,000 at 31 March 2001, the actuarial
value of the assets represented 110% of the ongoing past service liabilities of
the Scheme as at that date. The current contribution rate is 17.8% for the
Scheme.

For accounting purposes, the projected unit method has been adopted and the
main actuarial assumptions used to value liabilities are:

Investment return                          6.0% p.a.                    
                                                                        
Salary growth (excluding salary scale)     4.5% p.a.                    
                                                                        
Pension increases                          2.5% p.a.                    

The past service surplus in excess of the prepayment as at 31 March 2001 is
being amortised for accounting purposes over a nine year period at a constant
monetary amount.

Employer pension contributions paid into the Scheme during the year were �
2,125,000 (2001 - �1,738,000).

An amount of �325,000 (2001 - �300,000) has been charged to the 2002 Profit and
Loss Account in respect of the Scheme and a prepayment of �10,900,000 (2001 - �
9,100,000) has been included in the Balance Sheet as at 31 December 2002.

c) Serco GmbH & Co.KG Pension arrangement

The German pension arrangement comprises two elements; an unfunded defined
benefit arrangement and an unfunded hybrid scheme.

Actuarial assessments covering liabilities are carried out by independent
qualified actuaries, with the last such review being carried out as at 23
December 1999 and updated as at 31 December 2002 by a qualified independent
actuary.

The projected unit method was adopted for the actuarial valuation of the
arrangement. The main actuarial assumptions used in the valuation for
accounting purposes were:

Discount rate         6.0% p.a.          
                                         
Salary growth         3.0% p.a.          
                                         
Price inflation       1.0% p.a.          

The Profit and Loss charge for the year was �1,663,000 (2001 - �130,000) and a
provision of �25,808,000 (2001 - �23,003,000) has been included in the Balance
Sheet as at 31 December 2002 of which �20,271,000 (2001 - �17,466,000) relates
to the hybrid element of the Scheme and �5,537,000 to the defined benefit
element of the Scheme.

d) Serco Superannuation Fund

The defined benefit element of the Scheme was established in Australia on 1
April 1993 to provide equivalent benefits for members transferring from the AWA
Defence Industries Superannuation Fund, a defined benefit scheme.

Notes to the Preliminary Announcement

For the year ended 31 December 2002

31 Pension schemes (continued)

Actuarial assessments covering expenses and contributions relating to the
defined benefit element of the Scheme are carried out by independent qualified
actuaries, with the last such valuation being carried out as at 31 December
2000. The attained age method was used for the actuarial valuation of the
Scheme as at 31 December 2000. This method was chosen to produce a level
employer contribution rate as a proportion of members' salaries over the
expected future working lives of the existing members, as the defined benefit
element of the Scheme was closed to new members with effect from 1 April 1993.

The main actuarial assumptions used in the actuarial valuation for accounting
purposes were:

Average long-term interest rate (net of investments                      
                                                                         
and administration expenses and investment tax)         8.0% p.a.        
                                                                         
Average long term allowance for salaries increases      5.5% p.a.        

The defined benefit element of the Scheme was assessed to be fully funded on a
current funding level based on a market value of assets of �1,385,000
(A$3,938,000) at 31 December 2000 with a ratio of market value of assets to
current funding level liabilities of 107%.

The actuarial value of assets of the defined benefit element of the Scheme
represented 115% of its ongoing liabilities at 31 December 2000. The pension
cost calculated under the attained age method will amortise the above surplus
over the expected future working lives of the existing members which have an
average value of 11 years.

Employer pension contributions paid into the Scheme and charged to the 2002
Profit and Loss Account relating to the defined benefit element of the scheme
were �257,000 (2001 - �104,000).

independent qualified actuaries, with the last such review being carried out as
at 5 April 2001. The funding policy is to contribute such variable amounts as
will achieve 100% funding on a projected unit basis.

The average contribution rate is currently 20.8% for the scheme.

Investment return            6.50% p.a. (5.0% for current pensioners)    
                                                                         
Salary growth                4.25% p.a. (plus promotional scale)         
                                                                         
Price inflation              2.25% p.a.
