Item 10. Financial statements of certain bidders
To satisfy the requirements of the City Code, financial information for
Sema plc prepared in accordance with UK GAAP has been included in the
tender offer materials. UK GAAP differs in certain material respects from
US GAAP. A description of the differences between UK GAAP and US GAAP
significant to Sema's financial statements was included in Sema's
registration statement on Form F-4 (Registration number 333-11810). The
significant differences in accounting principles have been excerpted from
the Form F-4 as follows:
(i) Business combinations
Both US GAAP and UK GAAP require purchase consideration in respect of
subsidiaries acquired to be allocated on the basis of fair values to the
various net assets of the acquiree at the date of acquisition. The excess
of purchase consideration over the fair value of net assets acquired is
treated as goodwill. However, US GAAP also requires value to be assigned to
any separately identifiable intangible assets, which would be amortized
over their estimated useful lives not to exceed 40 years.
US GAAP requires goodwill to be recognized as an asset and amortised over
its estimated useful life not to exceed 40 years. Under UK GAAP, for the
years ended through December 31, 1997, goodwill may be written off directly
against reserves. For the year ended December 31, 1998 onward, UK GAAP
requires goodwill and any separately unidentifiable intangible assets to be
recognized as an asset and amortised over its estimated useful live. Except
in certain rare circumstances where a useful life can be regarded as
infinite, there is a rebuttable presumption that the useful life does not
exceed 20 years.
(ii) Earnings per share
The calculation and presentation of earnings per share (EPS) under UK GAAP
differs from that required under US GAAP. In accordance with US GAAP, basic
EPS is computed by dividing income available to common shareholders by the
weighted average number of common shares outstanding for the year. The
computation of diluted EPS is similar to basic EPS, except that it assumes
the potentially dilutive securities, such as convertible loans, were
converted to shares as of the beginning of the year or at the time of
issuance, if later. In addition, US GAAP requires presentation of basic and
diluted EPS using both income from continuing operations and net income.
(iii) Pensions
Under UK GAAP, the cost of providing pension benefits is expensed over the
average expected service lives of eligible employees in accordance with the
provisions of SSAP 24. SSAP 24 aims to produce an estimate of cost based on
long-term actuarial assumptions. Variations from the regular pension cost
arising from, for example, experience deficiencies or surpluses, are
charged or credited to the profit and loss account over the expected
average remaining service lives of current employees in the schemes.
Under US GAAP, the annual pension cost comprises the estimated cost of
benefits accruing in the period as determined in accordance with SFAS 87,
which requires readjustment of the significant actuarial assumptions
annually to reflect current market and economic conditions.
(iv) Holiday pay
US GAAP requires that provisions for employees' future absences (holiday
pay) shall be made on an accrual basis if (i) the employees right to
receive compensation for future absence is due to past service, (ii) the
obligation accumulates, (iii) the payment is probable and (iv) the amount
can be reasonably estimated. There are no formal rules under UK GAAP and
either the accrual or cash method is used in practice.
(v) Software development costs
It is Sema's policy to write off software development costs in the year in
which they are incurred unless they are to be reimbursed by third parties.
Under US GAAP, costs associated with the development of software products
to be sold or otherwise marketed should be capitalized subsequent to the
establishment of technological feasibility up until the product's general
release. These costs should then be amortized over the estimated economic
life of the software product.
(vi) Employee stock compensation
Under US GAAP, entities have a choice of methods for determining the costs
of benefits arising from employee stock compensation plans, being either
the "intrinsic value" method or a fair value method. Under the "intrinsic
value" method, compensation cost is the difference between the market price
of the stock at the measurement date and the price to be contributed by the
employee. Under the fair value method, compensation cost is based on the
estimated fair value of the option at the date of grant using an option
pricing model which considers: the stock price at grant date, the exercise
price and expected life of the option, expected volatility, expected
dividend yield and a risk-free interest rate.
Under UK GAAP, except for options issued under Inland Revenue approved
employee save as you earn (SAYE) schemes, compensation cost is the
difference between the market value of the shares at the date of grant of
the conditional award less contribution that the employee is required to
make.
(vii) Dividends
Under UK GAAP, dividends proposed are provided for in the year to which
they relate on the basis of recommendation by the Board of Directors for
approval by the shareholders. Under US GAAP, dividends are recorded as a
reduction in retained earnings only when they have been formally declared.
(viii) Contract accounting
Under US GAAP and UK GAAP income on contracts is recognized according to
the percentage of the estimated total contract value completed or the
achievement of contractual milestones. All contract losses are recognized
as soon as incurred or foreseen. However, under US GAAP, the choice of
recognition on a milestone basis is only permitted where the achievement of
the milestone approximates the percentage of completion of the contracts.
(ix) Restructuring provisions on acquisitions
The requirements for making a provision for restructuring costs when a
subsidiary is acquired are very prescriptive under both US GAAP and UK
GAAP. Under UK GAAP, restructuring provisions cannot be made as part of
fair value adjustments arising on an acquisition. Restructuring provisions
created prior to the acquisition can be maintained only if they were
demonstrably made prior to the management of the target company
contemplating the transaction. These restructuring provisions were mainly
severance related. Under US GAAP acquisition provisions are governed by
EITF 95-3 which require specific criteria to be met such as the plan
formulated at the acquisition date to terminate employees or exit an
activity be finalized beyond one year from the consummation of the merger.
If the provisions are utilized in years subsequent to the acquisition, a US
GAAP difference arises to reverse the credit to the profit and loss
account.
(x) Deferred taxation
Under UK GAAP, a provision is recorded for deferred taxation under the
liability method to the extent that such taxation is expected to
crystallize within the reasonable future. This means that the full
potential liability is not necessarily provided. Additionally, deferred tax
assets are recognized only when they are expected to be recoverable within
the foreseeable future.
Under US GAAP, deferred tax is provided for on a full liability basis.
Under the full liability method, deferred tax assets or liabilities are
recognized for differences between the financial and tax basis of assets
and liabilities and for tax loss carry forwards at the statutory rate at
each reporting date. A valuation allowance is established when it is more
likely than not that some portion or all of the deferred tax assets will
not be realized.
(xi) Investments
Under UK GAAP, investments in marketable securities are recorded at cost.
Under US GAAP, an adjustment to add the unrealized gain, net of related
taxes, to the cost of the investment is made on available for sale
securities.
(xii) Cash flow information
Under UK GAAP, the Consolidated Cash Flow Statements are presented in
accordance with UK Financial Reporting Standard No. 1, as revised (FRS 1).
The Statements prepared under FRS 1 present substantially the same
information as that required under US GAAP as required by SFAS No. 95.
Under UK GAAP, the Company's cash comprises cash in hand and at bank (net
of bank overdrafts). Under US GAAP, cash and cash equivalents include cash
and short-term investments with original maturities of three months or
less. Under US GAAP, bank overdrafts are classified within financing
activities, and cash and cash equivalents are not offset by book overdrafts
repayable within 24 hours from the date of the advance, as is the case
under UK GAAP.
Under UK GAAP, cash flows are presented for operating activities: dividends
received from associated undertakings; returns on investments and servicing
of finance; taxation; capital expenditure and financial investment;
acquisition and disposals; equity dividends paid; management of liquid
resources and financing. US GAAP requires the classification of cash flows
as resulting from operating, investing and financing activities.
Cash flows under UK GAAP in respect of interest received, interest paid,
investment income and taxation would be included within operating
activities under US GAAP. Capital expenditure and financial investment and
cash flows from acquisitions and disposals would be included within
investing activities under US GAAP. Dividends paid by subsidiary
undertakings, minority interests, equity dividends paid and management of
liquid resources would be included within financing activities under US
GAAP.
(xiii) Borrowings
Both UK and US GAAP require issue costs to be capitalized and amortized
over the term of the borrowing to which they pertain. Under UK GAAP, issue
costs are classified net of the borrowings to which they relate. Under US
GAAP, issue costs are classified as an other long term asset.
(xiv) Contract maintenance
Under UK GAAP, the cost of the licence acquired is capitalized and
amortized over the life of the contract. Under US GAAP, where the cost of a
licence acquired includes future maintenance services, the fair value of
the maintenance charge in these services must be imputed and amortized over
the life of the contract.
(xv) Fair value adjustments
Under UK GAAP, fair value adjustments on acquisitions can only be revised
at the second balance sheet date after an acquisition if they have been
described as provisional in the accounts as at the first balance sheet
date.
Under US GAAP, fair value adjustments can be revised for up to one year
after the date of acquisition.
