10. SUMMARY OF DIFFERENCES BETWEEN ACCOUNTING PRINCIPLES GENERALLY ACCEPTED IN THE UNITED KINGDOM AND THE UNITED STATES OF AMERICA

The Group's condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United Kingdom (“UK GAAP”), which differ in certain respects from accounting principles generally accepted in the United States of America (“US GAAP”). Differences which have an effect on the consolidated net income, shareholders' equity and financial position of the Group are set out below.

Effect of differences between UK GAAP and US GAAP on loss after tax:

7

Effect of differences between UK GAAP and US GAAP on net equity:

Under UK GAAP, minority interest is deducted in determining the loss for the period. Under US GAAP, minority interests (called non-controlling interests) are not deducted in arriving at net loss for the period. Instead the net loss for the period is allocated between the non-controlling interests and the parent company shareholders.

US GAAP contains more detailed requirements to be met in order to recognise revenue when compared with UK GAAP. This adjustment defers revenue relating to two areas:

On 16 November 2006, SHL Group Holdings 1 Limited acquired 100% of the share capital of SHL Group Limited for £102.3m. Separately identifiable intangible assets totalling £60.0m have been recognised under US GAAP and are being amortised over their respective useful economic lives of between 5-20 years.

On 11 January 2011, SHL Group Holdings 3 Limited, previously a 100% subsidiary of SHL Group Holdings 1 Limited, acquired all the issued share capital of PreVisor Inc. SHL Group Holdings 3 Limited issued 1.7m shares to Qwiz Holdings LLC, PreVisor Inc’s former parent, in consideration for the acquisition. Separately identifiable intangible assets totalling £53.4m have been recognised under US GAAP and are being amortised over their respective useful economic lives of between 5-20 years.

Under UK GAAP, goodwill arising on an acquisition is typically denominated in the currency of the acquirer, which in the case of the acquisitions to date was Sterling. Under US GAAP, goodwill and intangibles are recorded in the functional currency of the operations to which they relate.

The amounts are retranslated at each balance sheet date with the foreign exchange gain or loss being recorded directly within reserves.

8

Under UK GAAP, the Group does not recognise derivatives at fair value on the balance sheet nor mark-to-market amounts in net income. Interest differentials on derivative instruments are charged to the profit and loss account as interest costs in the period in which they are realised. Monetary assets and liabilities denominated in foreign currencies that are hedged by a foreign currency derivative are translated using the contract rate in the hedging derivative.

Under US GAAP, hedge accounting is permitted only when, inter alia, the hedging relationship is documented formally. Derivatives that are not designated in a hedging relationship are recognised at fair value with gains and losses recognised in the profit and loss account. Since the Group had not formally documented its hedging relationship in accordance with US GAAP an adjustment is made to record the fair value of derivatives on the balance sheet with the movement in fair value recorded in the income statement each period.

Under US GAAP, the estimated amount of interest incurred in connection with the internally developed software is calculated by applying the interest rates applicable to borrowings outstanding during each applicable period. Upon completion of the asset, this amount is considered part of the deemed cost of software and is depreciated over the life of the related assets. All interest is expensed as incurred under UK GAAP.

Under US GAAP, deferred taxes are presumptively recognised on unremitted earnings related to foreign subsidiaries unless there is sufficient evidence that the subsidiary will invest the undistributed earnings indefinitely. For a domestic subsidiary a deferred tax liability is recognised unless the investment in that subsidiary can be recovered in a tax free manner and management intends and expects to recover the investment in a tax free manner.

Under UK GAAP, deferred tax assets are recognised only to the extent that, on the basis of all available evidence, it is considered that there will be sufficient future profits from which the reversal of the timing losses can be deducted. There is a general acceptance that an entity would look out between 1-3 years when considering future profitability to evaluate the probability of realising the assets. Under US GAAP, there is no accepted cap on the look-out period when the company has a history of profitability.

As a result of the accounting adjustments discussed in (i) above, a number of deferred tax liabilities were recognised. When a deferred tax liability is recognised in a particular tax jurisdiction, in some cases deferred tax assets not recognised under UK GAAP were recognised when those assets are likely to reverse in a similar time period and the same tax jurisdiction.

Under UK GAAP, deferred tax assets and liabilities are off-set across different tax jurisdictions and the net amount is presented with debtors, if a net asset, or with provision for liabilities, if a net liability. Under US GAAP, deferred taxes are classified in the balance sheet according to the classification of the balance sheet item to which they relate. Therefore deferred tax liabilities related to intangible assets are classified as long term liabilities. Deferred tax assets and liabilities are only off-set to the extent that they are short term or long term and are in the same tax jurisdiction.

SHL, through its subsidiary SHL US Inc (“SHL US”, formerly PreVisor Inc), owns 100 percent of the shares in Personnel Decisions Research Institutes, Inc. (“PDRI”). PDRI performs services for various agencies of the US Government. A US company is considered to be under foreign ownership, control or influence (“FOCI”) when a foreign company has the power to direct matters affecting the management or operations of the company in a manner which may result in unauthorized access to classified information or may affect adversely the performance of classified contracts. A US company under FOCI is not security cleared to perform US governmental work (i.e. not eligible for facility security clearance) until the FOCI issue is mitigated.

As SHL was owned by non-US nationals, the Department of Defence (“DSS”) required that a Proxy Board be established to run PDRI in order to mitigate the FOCI issue and enable PDRI to continue to deliver the contracts it had with the various US Government agencies. The Proxy holders must satisfy certain conditions, including having no prior affiliation with SHL or its affiliates. In the event of an acquisition by a US based company, provided that there are no non-US intermediate holding companies in the group structure, management believes that it should be possible to dissolve the Proxy Board.

The initial Proxy Holders were chosen by SHL although subsequent appointments are made by the existing proxy holders or the US government. The Proxy Holders are directors of PDRI and have the right to appoint and remove any directors of PDRI at their sole discretion. The Proxy Holders direct the operations of PDRI although they are not able to sell any assets of the business or enter in any business combinations or disposals without the express approval of SHL.

The Proxy agreement specifies the powers that the Proxy Board is able to exercise with respect to its governance of PDRI. Under UK GAAP, SHL consolidates PDRI as a subsidiary because it is able in practice to exercise dominant influence over PDRI by virtue of the fact that it has veto rights over material changes to the operations of PDRI, for example PDRI’s ability to raise capital, invest in capital expenditure, acquire other businesses or the Proxy Board’s ability to liquidate PDRI.

Under US GAAP, PDRI meets the definition of a variable interest entity as the equity holders in PDRI as a group do not have the legal ability, through voting rights or similar rights, to direct the activities of PDRI that most significantly impact PDRI’s economic performance. SHL is not the primary beneficiary of PDRI because it does not have the power to direct the activities of PDRI that most significantly impact its economic performance. SHL’s legal rights do provide it with significant influence and therefore under US GAAP it accounts for its investment under the equity method.

This has no impact on net income and shareholders’ equity as reported under UK GAAP to that which would be reported under US GAAP; however, it does have an impact on the amounts reported in the profit and loss account and balance sheet.

Set out below are the amounts included in the consolidated financial statements under UK GAAP with respect to PDRI, which would be reported in a single line as “Share of equity method investee” in the profit and loss account and as a single line “Investment in equity method investee” in the balance sheet under US GAAP:

Certain of the US GAAP adjustments included in the reconciliation of loss for the period and net liabilities relate to PDRI. Under US GAAP, these adjustments would be included in the line “Share of equity method investee” in the profit and loss account and in the line “Investment in equity method investee” in the balance sheet under US GAAP. The tables below summarise the US GAAP adjustments attributable to PDRI:

(h) EXPLANATION OF UK GAAP—US GAAP DIFFERENCES NOT QUANTIFIED

Under UK GAAP, the Group’s financial statements include a cash flow statement in accordance with FRS 1 (revised 1996), “Cash Flow Statements”. This statement presents substantially the same information as that required under ASC 230, “Statement of Cash Flows”. ASC 230 only requires presentation of cash flows from operating, investing, and financing activities. Set out below, is a summary consolidated statement of cash flows presented using the captions under US GAAP:

Classification differences between UK and US GAAP

In addition to the differences between UK and US GAAP related to the recognition and measurement of transactions by the Group, there are also a number of differences in the manner in which items are classified in the consolidated profit and loss account and consolidated balance sheet. These classification differences have no impact on net income or shareholders’ equity.

Under UK GAAP, the balance sheets are presented in ascending order of liquidity, whereas under US GAAP assets are presented in descending order of liquidity. Also under UK GAAP, the balance sheet is analysed between net assets and shareholders’ funds. Under US GAAP, the analysis is between total assets and total liabilities plus shareholders’ equity. Certain items which are disclosed in the notes under UK GAAP would be disclosed on the face of the balance sheet under US GAAP. Also, under US GAAP, debtors due after more than one year of £0.1m (2011: £0.3m) (included under current assets in the UK GAAP financial statements) would be classified under long term debtors.

Provisions for liabilities and charges

Provisions for liabilities and charges under UK GAAP include £0.3m (2011: £0.3m) that are due within one year and which would be reclassified to current liabilities under US GAAP.

Exceptional items

Under UK GAAP, exceptional items are material items that derive from events or transactions that fall within the ordinary activities of a reporting entity and which individually or, if of a similar type in aggregate, are required or expressly permitted to be disclosed by virtue of their size or incidence if the financial statements are to give a true and fair view. Details of the exceptional items are set out in Note 3.

Under US GAAP, all exceptional items would not have been separately presented.

11. POST BALANCE SHEET EVENTS

On 2 August 2012 The Corporate Executive Board Company (“CEB”) acquired the entire share capital of SHL Group Holdings 1 Limited for $660 million. As part of the acquisition the Group repaid its remaining bank debt of £36.3m and shareholder loans due to Hg Capital of £108.4m. Additionally, the Group settled its interest rate swap when the bank loans were repaid, with a loss on settlement of £0.6m.
