Chairman's and Chief Executive's statement

Introduction

2011 was a year of successful strategic repositioning for the Group as wecompleted the acquisition of PSN and the disposal of the Well Support divisionto focus on our market leading positions in engineering, production facilitiessupport and gas turbine services.Overall, it has been a year of strong growth. In Engineering, increasedactivity in upstream and subsea & pipelines led to higher revenues and improvedmargins. We have largely completed the integration of the PSN acquisition withWood Group's Production Facilities business, to create Wood Group PSN, and areon track to deliver expected synergies. The PSN acquisition has performed aheadof expectations. Overall, Wood Group PSN performance benefited from strength inthe North Sea and North America, but was held back by previously announcedlosses on Wood Group Production Facilities contracts in Oman and Colombia. InWood Group GTS, we saw strong revenue growth and margin improvement in ourMaintenance business and good progress in Power Solutions, which recognisedsignificant levels of profit in the second half.In support of our continued development, we formalised the common values andculture which unite the Group. These Core Values - Safety & Assurance,Relationships, Social Responsibility, People, Innovation, FinancialResponsibility and Integrity - define who we are, what we believe in, set outhow we act and how we expect to be treated, and provide a sound basis to makedecisions.2011 Group performance 2011 2010 % $m $m Change Total revenue1 6,052.3 5,063.1 19.5%

Note: Total revenue and EBITA figures represent the sum of the Group's continuing operations and Well Support activity up to the date of disposal. Continuing operations revenue and EBITA figures include the results of PSN since acquisition, and exclude the results of Well Support in the period prior to its disposal and those of the Wood Group GTS Aero engine overhaul business.

Total revenue increased by 20% and total EBITA was up 16%. Revenue increasedstrongly in all divisions, including the impact of PSN results from 20 April.Revenue from continuing operations increased by 39% and EBITA from continuingoperations increased by 56% to $341.6m. Continuing operations EBITA margin("margins") increased by 0.6 percentage points due to improved margins in alldivisions.

Adjusted diluted EPS increased by 51% to 60.2c, reflecting the increased EBITA in the period, lower finance expense, the lower effective tax rate and the favourable impact of the share reduction related to the return of cash.

Reflecting our confidence in the longer term outlook for the Group, we are declaring a final dividend of 9.6 cents which will bring the full year dividend to 13.5 cents, up 23% on 2010. This takes the annual compound growth in dividends since our IPO in 2002 to 18%.

Markets

Conditions in oil & gas markets remained strong. Some uncertainty around theglobal economic outlook remains, but we believe that energy market fundamentalswill continue to be driven by supply side challenges coupled with rising globalenergy demand over the longer term. In 2011, there was good growth in global E&P spend and this is forecast to increase by around 5% - 10% in 2012. E&P spendhas a particular benefit for our Engineering activities focused on clients'development related capex and we remain encouraged by our order book &prospects list. For Wood Group PSN, we believe the market for our brownfieldproduction support services will expand as the number of assets increases andages, and operators increasingly focus on asset integrity, process safety,performance assurance and production enhancement.Economic conditions for our power customers in Europe and North Americaremained challenging, although our Wood Group GTS maintenance business secureda number of new awards, and levels of interest in our fast track powersolutions offering remain strong, particularly in emerging economies. Thegrowth in global electricity demand over the longer term, relatively favourablegas prices and environmental considerations continue to support the futureprospects for gas fired power generation.

Strategy

In 2011, we completed the acquisition of PSN for a consideration of around $1bnand the disposal of the Well Support division for $2.8bn and these stepsenhanced the Group's strategic focus and market leading positions. Followingcompletion of the transactions, we returned £1.1bn in cash to shareholdersthrough a tender offer and B/C share scheme.

The strategy of the refocused group has four strands:

To maintain a balance between development and later cycle production support

To grow and maintain our market leading positions, based on differentiated know how, innovation and technical capabilities

To develop long term customer relationships often through performance based contracts

To extend our services within our three core businesses and broaden our international presence

In pursuit of this strategy, and in addition to the PSN acquisition, wecompleted the acquisitions of Dar E&C and Pi-Consult to enhance our Engineeringcapability in Saudi Arabia. We also established a joint venture in Kuala Lumpurand acquired ISI Solutions in Argentina to provide engineering and consultingservices to markets in South East Asia and Latin America. In Angola, weestablished the Wood Group Kianda joint venture to provide engineering andproduction facilities support services. In Wood Group GTS we took a number ofsteps to improve our differentiation, including the acquisitions of IMS and GasTurbine Efficiency, and the formation of a strategic alliance with Pratt &Whitney Power Systems to service the important frame 7 FA aftermarket.

The Board

Bob Keiller joined the Board on 20 April 2011 as Group Director, Wood GroupPSN, following the completion of the PSN acquisition. Jim Renfroe, GroupDirector, Well Support, resigned from the Board on 26 April following the saleof the division. We thank Jim for his considerable achievements in leading theWell Support division during his tenure with the Group. John Ogren resigned asa non-executive director after 10 years on the Board at the 2011 AGM. We areimmensely grateful for John's contribution, in particular his broad industryknowledge, both as an operator and a contractor, and insight into events andmarket trends in North America. Jeremy Wilson was appointed as a newnon-executive director on 1 August 2011.

Risks and Uncertainties

Risks and uncertainties are inherent features of the oil & gas and power services industries and provide challenges that cannot be completely eliminated. However, we assess risk carefully and mitigate where we can to ensure that we keep our people safe, serve our customers well and, at the same time, achieve acceptable returns for our shareholders.

The Board has overall responsibility for ensuring that, where possible, risk ismanaged effectively as part of the established governance structure. In 2010,the Board prepared a statement of its attitude to risk which has been updatedin 2011 following the sale of Well Support and the acquisition of PSN.

Safety & Assurance

Safety & Assurance is our top priority and first Core Value. Over many years wehave reduced injury rates to our people whilst growing our workforcesignificantly. This continued in 2011 with a 31% reduction in lost time injuryrate and an 11% reduction in total recordable injury rate, compared to 2010.However, two incidents provided a stark reminder of the need for a continuedfocus on safety improvement; two engineers died in a road traffic accident inSaudi Arabia and one technician died following the collapse of a customer cranein the Gulf of Mexico. Lessons have been learned and actions taken to improverisk management as a result. Management remain committed to a relentless focuson safety & assurance improvement and continue to invest in appropriateleadership and technical safety training.

Outlook

We anticipate good progress in all divisions in 2012.

In our activities supporting clients' development capex, we are forecastingstrong growth in Engineering driven by increased E&P capex spend and have goodvisibility in our Wood Group GTS Power Solutions business into 2012. In ouractivities supporting clients' production opex activities, we see performanceimprovement in Wood Group PSN and further growth in Wood Group GTS Maintenance.Through our market leading positions in engineering, production facilitiessupport and gas turbine services, we are well positioned to take advantage ofstrong growth trends in energy markets and we continue to anticipate goodgrowth in the longer term.Operational ReviewEngineeringWe provide a wide range of engineering services to the upstream, subsea &pipelines, downstream & industrial and clean energy sectors. These includeconceptual studies, engineering, project & construction management (EPCM) andcontrol system upgrades. 2011 2010 % $m $m Change Revenue 1,458.6 1,239.1 17.7% EBITA 162.0 122.0 32.8% EBITA margin 11.1% 9.8% 1.3pts People5 9,100 6,900 29% Engineering revenue increased by 18% reflecting increased activity in upstreamand subsea & pipelines, with downstream, process & industrial activityremaining broadly in line with the prior year. EBITA increased 33% with marginincreasing from 9.8% to 11.1%, generally reflecting higher volumes and someimprovements in utilisation and pricing.Headcount increased from 6,900 to 9,100 in response to increased demand for ourservices in upstream and subsea & pipelines, together with the impact of theacquisitions of Dar E&C and Pi-Consult in Saudi Arabia and ISI Solutions inArgentina, which together added around 500 people.Our upstream business accounted for around 40% of Engineering revenue. Wedelivered good growth in the US where we remain active on projects includingthe detailed engineering scope for the Anadarko Lucius and Chevron Jack & StMalo projects in the Gulf of Mexico, the Noble Alen project in EquatorialGuinea and the onshore Hess Tioga gas plant expansion in the US. In Canada, wesecured a two year framework agreement with Shell covering Western Canada andoffshore Alaska, and our activities in support of developments in the oil sandsmarket performed strongly. We made further progress in Saudi Arabia, where wewere awarded a multi-year engineering services framework agreement by SaudiAramco, following the acquisitions of Dar E&C and Pi-Consult. In Malaysia, ournewly established joint venture was awarded its first contracts. During theperiod we also announced the acquisition of ISI Solutions in Argentina, tosupport the provision of engineering and consulting services to the LatinAmerica market.Our subsea & pipeline business accounted for around 40% of Engineering revenueand continues to perform strongly. We are currently working on over 20 majorsubsea projects globally, including key projects for BP in Azerbaijan andAngola, and Shell in Malaysia. Activity remains high in Australia where we wererecently awarded the FEED work for the Equus project by Hess and where wecontinue to work for Chevron on the Gorgon project and Woodside on the Browsedevelopment. We also experienced notable growth in the UK where we secured theengineering design and project management work for BP's Quad 204 project. Ouronshore pipelines business performed well, benefitting from liquids focusedactivity in the US shale regions.Our downstream, process & industrial activities accounted for around 20% ofrevenues and performance in 2011 was broadly in line with 2010. The downstreamrefining market in North America remains flat, although we are beginning to seeearly signs of improvement in the process & industrial market.

Outlook

Our current order book represents around 8 months of forecast revenue followinga good increase in the first two months of the year, and we have a strongprospects list. Recent contract awards, including the Ichthys detailedengineering scope for Samsung, the Tubular Bells topsides work for WilliamsPartners and our subsea engineering framework agreements with Shell, supportour expectation of further growth in upstream and subsea & pipelines in 2012.In downstream, process & industrial, we anticipate that performance in 2012will be largely in line with 2011, due to ongoing weakness in the market inNorth America.Forecasts of growing global E&P capex spend underpin our confidence in thelonger term prospects for Engineering. We see good opportunities for furthergrowth and will continue to broaden our international presence and serviceoffering as customers seek to replace and grow reserves in increasingly complexdevelopments.Wood Group PSN

We provide life of field support to producing assets through brownfield engineering and modifications, production enhancement, operations and maintenance (including UK duty holder status), training, maintenance management and abandonment services.

2011 2010 % $m $m Change Revenue 3,012.7 2,041.1 47.6% EBITA 153.2 101.4 51.1% EBITA margin 5.1% 5.0% 0.1pts People5 26,200 14,500 80.7% Revenue and EBITA include the results of PSN from the date of acquisition on 20April 2011 to 31 December 2011, amounting to revenue of $992.5m and EBITA of$92.8m.

Wood Group PSN was formed through the merger of Wood Group Production Facilities with PSN, to create the global market leader in brownfield production facilities support, which now employs over 26,000 people. The integration programme is largely complete and we are on track to deliver expected synergies.

Revenue increased by 48% and EBITA increased by 51% in the period, due to thecontribution of the acquired PSN business which performed ahead of ourexpectations. Overall performance benefited from strength in the North Sea andNorth America, but was held back by losses of around $30m on Wood GroupProduction Facilities work in Oman and Colombia. Losses in Oman will continueto impact in 2012, although we anticipate that this will be at a reduced levelcompared to 2011.We experienced strong demand in the North Sea, which remains our largest marketand accounted for around 40% of revenue compared to 54% for the ProductionFacilities business in 2010. During 2011 we secured a number of major contractextensions, including the operations & maintenance contract with Talisman, andour operations, maintenance and engineering contract with Taqa Bratani, bothfor five years. We also recently extended an onshore contract with Shell andhave been awarded a new contract with Premier Oil to support the Balmoralfloating production vessel. These contracts provide good earnings visibilityand we believe demonstrate the strong level of customer support for the mergedbusiness.The Americas accounted for around 30% of revenue. Our offshore activities inthe Gulf of Mexico performed well and we were also awarded the projectcommissioning work for the Jack & St. Malo development for Chevron. Demand forour US onshore services, including in the shale regions, strengthened throughthe year and we see good growth prospects for our operations support,consultancy and training services. In Latin America, we have fully provided foranticipated losses to completion on a fixed price downstream project forEcopetrol in Colombia. We have strengthened the management team in Colombia andexpect to complete the project in the second half of 2012, in line with ourcost estimates.International markets, outside the North Sea and the Americas, represent around30% of revenue. In Oman, difficulties in the start up and mobilisation of ourseven year engineering and maintenance services contract with PDO resulted inlower than anticipated utilisation and this contributed to losses. We havecontinued to strengthen the management team in Oman and have now fully takenover responsibility from the previous contractor. We currently anticipatereduced losses in Oman in 2012 and that the contract will become profitablefrom 2013. In Australia, we delivered good profits from work with customersincluding Exxon in the Bass Strait. In Africa, we continue to be active oncontracts in Cameroon, Chad, Equatorial Guinea, Nigeria and Angola, where ourWood Group Kianda joint venture has recently secured the topsides maintenancescope for BP for Block 31. In Russia, we extended our contract with SEIC inSakhalin for a further five years and in Kazakhstan, we are working forTengizChevroil and AGIP KCO.

Outlook

The integration of PSN is largely complete and we are on track to deliverexpected synergies. Recent contract wins and extensions demonstrate the stronglevel of customer support for the merged business which we believe is unique inits international reach. Improved performance in 2012 will be led by theelimination of losses in Colombia, reduced losses in Oman and continuedstrength in the North Sea, North America and Africa.

Looking further ahead, we believe there are significant opportunities to deliver our high quality, high integrity services in good long term growth markets as the industry increasingly focuses on operational assurance, competency, reliability and asset integrity.

Wood Group GTS

We are a leading independent provider of rotating equipment services and solutions for clients in the power, oil & gas and clean energy markets. Our aftermarket Maintenance activities include facility operations & maintenance and repair & overhaul of gas, wind and steam turbines, pumps and other high-speed rotating equipment. Our Power Solutions business provides power plant engineering, procurement & construction and construction management services to the owners of power-generation facilities.

Headcount increased due to higher activity in Power Solutions, offset to some extent by a net reduction in Maintenance headcount as a result of operating efficiency initiatives.

Maintenance revenues increased by 10% to $784m and EBITA increased by over 20%,primarily due to improved performance in our oil & gas related activities,which benefitted from steps taken to enhance our operating efficiency andproduct capability, together with a good contribution from our activities inIraq.In our power related activities, we made a number of strategic moves to enhanceour differentiation. We formed a strategic alliance with Pratt & Whitney PowerSolutions to better service the GE 7FA turbine aftermarket and alsosignificantly enhanced our combustion technology capability. Overall, themarket remained challenging, but we saw good performance on some longer termcontracts and secured a number of new awards including the AssociatedElectrical Cooperative in the US for 7FA equipment maintenance, the MunicipalUtility District Financing Authority in Sacramento California, EGASA in Peruand PlusPetrol in Argentina.In Power Solutions, good progress on the Dorad and GWF contracts resulted inthe recognition of significant levels of EBITA in the second half. We arepursuing a number of additional prospects in Power Solutions, and Dorad and GWFprovide good visibility into 2012.

Outlook

2011 saw a strong recovery in our Maintenance activities and, despite achallenging power market, we anticipate further growth in 2012. In PowerSolutions, we have good visibility on work and anticipate strong EBITA growthin 2012 as the Dorad and GWF projects progress. There is good demand for ourfast track EPC Power Solutions offering and, despite constraints in the projectfinancing market, we are pursuing a number of additional prospects.In the longer term, forecast growth in global electricity demand, relativelyfavourable gas prices and environmental considerations all continue to underpinan excellent long term market for gas fired power generation.Financial ReviewFinancial Performance Full Full % Year Year Dec 2011 Dec 2010 Change $m $m Total revenue 6,052.3 5,063.1 19.5%

The results for the year have been impacted by the acquisition of PSN on 20 April 2011 and the disposal of the Well Support division on 26 April 2011.

A review of our trading performance is contained within the Chairman's and Chief Executive's Statement, along with the Operational Review.

On a pro forma basis, which includes PSN revenue and EBITA for the full year,including the pre-acquisition period, and excludes the results of Well Support,the performance for the continuing Group in 2011 would have been as set out

below.Unaudited Full Year Full Year % Dec 2011 Dec 2010 Change $m $m Engineering 1,458.6 1,239.1 17.7% Wood Group PSN 3,376.0 3,215.3 5.0% Wood Group GTS 1,195.5 804.9 48.5%

Pro forma EBITA from continuing operations 363.6 315.4 15.3%

The pro forma result highlights underlying growth in revenue and EBITA of around 15%. On a pro forma basis Wood Group PSN EBITA has reduced by 11.6%, primarily due to the losses recognised in Colombia and Oman as previously announced and noted in the Operational Review.

Commentary on other items relevant in arriving at the Group's financial performance for the year is set out below.

Amortisation

The amortisation charge of $78.7m includes $56.8m (2010: $10.5m) ofamortisation relating to intangible assets arising from acquisitions, of which$47.4m relates specifically to the PSN acquisition. The total intangible assetrecognised in relation to the acquisition of PSN was $194.5m and will beamortised over a period of five years. The total amortisation charge onintangible assets arising from acquisitions for 2012 is expected to be around$55.0m, of which it is anticipated that around $49.0m will relate to PSN. Weregard the amortisation charge relating to intangible assets arising onacquisitions to be a relatively subjective measure, and as a result continue tobelieve that performance is best measured excluding this figure. This is one ofthe primary reasons for our key reporting measures for profit and earnings pershare excluding the impact of amortisation.

Net finance expense

The net finance expense from continuing operations of $8.8m is analysed furtherbelow: Full year Full year Dec 2011 Dec 2010 $m $m Interest on debt 9.0 20.0 Non utilisation fees 2.3 5.1

Non cash charges on pension and deferred 1.3 1.8 consideration Bank fees and charges 1.1 8.4 Total finance charge from continuing operations 13.7 35.3 Finance income (4.9) (1.8) Net finance expense from continuing operations 8.8 33.5 Interest cover7, based on EBITA from continuing operations was 38.8 times(2010: 6.5 times).Exceptional Items Full year Dec 2011 $m

Business divested or to be divested (2,293.7)

Acquisition costs 15.8 Integration and restructuring 84.2 charge Political disruption 13.0 Impairment of goodwill 46.2

Total exceptional items before tax (2,134.5)

Tax on exceptional items 46.9

Total exceptional items after tax (2,087.6)

As set out in the table above we recorded a net exceptional gain of over $2bnin the year, primarily in relation to the gain on divestment of our WellSupport division. During the year we also recorded exceptional costs inrelation to the strategic repositioning of the Group. The majority of thesecosts were directly related to the acquisition of PSN, the integration of theresulting Wood Group PSN division, and decisions made to withdraw from certaingeographical markets.

As a result of the political disruption earlier in 2011 we also recorded an exceptional charge in relation to some overdue Libyan receivables, and we wrote down the goodwill associated with a GTS power related business.

Further details are provided in Note 4 to the Group financial statements.

Costs in relation to the return of cash to shareholders of $14.9m were incurredand a foreign exchange loss of $13.4m ($9.8m net of tax) arose on the sterlingbalances held in anticipation of the return of cash and these have been takendirectly to retained earnings.

Taxation

The effective tax rate on continuing operations pre exceptional items was 29.5%(2010: 34.7%). Full year Full year Dec 2011 Dec 2010 $m $m

Profit from continuing operations before tax 254.1 156.2 Add amortisation of intangibles arising on - 10.5 acquisition Adjusted Profit 254.1 166.7 Underlying tax charge 91.8 57.9

Credit in relation to deferred tax on amortisation of intangibles arising on acquisition (16.8) - Tax charge per financial statements 75.0 57.9 Effective tax rate on Continuing Operations 29.5% 34.7% The higher rate in 2010 relates primarily to unrecognised tax losses and thebooking of further provisions in overseas jurisdictions. Following the sale ofWell Support and acquisition of PSN, we expect the typical rate to be no morethan 29.0% with the reduction including the change in geographic mix of theGroup, reduced rates in certain jurisdictions and certain management actionstaken.Earnings per share

Adjusted diluted EPS for the year to 31 December increased by 51% to 60.2c, largely as a result of the increased EBITA in the period, lower net finance charges, a lower effective tax rate and a reduction in the weighted average number of fully diluted shares following the return of cash.

Dividends

The proposed final dividend is 9.6c. This results in a full year dividend of13.5c, an increase of 23% from last year, and an annual compound growth individends since our IPO in 2002 of 18%. Dividend cover8 for 2011 was 4.5 times(2010: 3.6 times).Summary Balance Sheet 2011 2010 $m $m Assets Non-current assets 1,873.9 1,059.4 Current assets 2,007.1 1,921.1 Liabilities Current liabilities (1,505.2) (1,230.7) Net current assets 501.9 690.4 Non-current liabilities (401.3) (332.6) Net assets 1,974.5 1,417.2 Total shareholders' equity 1,964.5 1,406.3 Minority interest 10.0 10.9 Total equity 1,974.5 1,417.2

Non-current assets are primarily made up of goodwill and intangible assets, andproperty, plant and equipment. The increase from December 2010 is primarily dueto the acquisition of PSN during the year.

Capital Efficiency

The Continuing Group's Return on Capital Employed4 ("ROCE") decreased from 19.5% to 18.4%. The decrease reflects the higher total capital employed following the acquisition of PSN, partially offset by higher EBITA in the period.

The Group's ratio of Operating Capital Employed to Revenue9 ("OCER") has improved from 14.0% to 10.6% at 31 December 2011, reflecting the less operating capital intensive nature of the restructured Group.

Return of cash and share consolidation

In February 2011, we announced that following the completion of the acquisitionof PSN and the disposal of our Well Support division to GE, we intended to makea return of cash to shareholders of not less than $1.7bn. In May 2011 weannounced that the Board had decided that the most appropriate process foreffecting the return of cash was, in the first instance, a Tender Offer of upto £1.1bn, followed by a subsequent B/C Share Scheme.At the close of the Tender Offer on 2 June 2011, 65.9m Wood Group shares,representing approximately 12.2% of the issued ordinary share capital, had beentendered and were purchased by the Group at a price of 625 pence per share, fora total value of £411.9m ($675.7m). Following completion of the Tender Offer,the Company announced that it would complete the return of cash through areturn of 140 pence per share to all shareholders on the register on 1 July2011. The return was made through a B/C Share Scheme, which was substantiallycompleted on 8 July 2011.At the date of this report we have successfully completed the return of £1,071.4m ($1,750.8m), with a further £4.7m ($7.7m) expected to be returned whenthe B shares issued pursuant to the deferred capital option under the B/C ShareScheme are redeemed in April 2012. This will take the total expected return to£1,076.1m ($1,758.5m).

The net cash impact on the Group of the return of cash in 2011 was $1,725.8m reflecting the receipt of $25.0m by the employee share trusts.

Concurrent with the B/C Share Scheme, the Company undertook a share capitalconsolidation. The purpose of the share capital consolidation was to seek toensure that, subject to market fluctuations, the market price of Wood Groupordinary shares immediately following the B/C share issue was approximately thesame as the market price immediately beforehand. The share capitalconsolidation also allows historical and future financial information inrelation to the Company to be compared on a per share basis before and afterthe B/C Share Scheme.The amount returned under the B/C Share Scheme represented approximately 21.9%of the Company's market capitalisation on 10 June 2011. As a result of theshare capital consolidation, the number of ordinary shares in issue has beenreduced by a broadly equivalent percentage, shareholders having received 7 newordinary shares for every 9 existing ordinary shares held. Following thecancellation of the ordinary shares purchased under the Tender Offer, therewere 474.9 million ordinary shares in issue. On 4 July 2011, following thecompletion of the share capital consolidation, there were approximately 369.4million new ordinary shares in issue.The weighted average number of fully diluted shares in the year to 31 December2011 was 448.8m.

Average net debt since the completion of the return of cash to shareholders hasbeen $128.0m. We have disclosed this average since the return of cash, as theproceeds held following the disposal of Well Support would significantlydistort the average net debt for the full year.Cash generated from operations pre working capital increased by $49.7m to$471.6m and working capital outflows from continuing operations were $109.5m(2010: inflow of $23.5m). The increase in net working capital reflectedincreased revenues, together with the impact of lower advance payments on GTSfixed price contracts and slightly reduced working capital efficiency.Cash paid in relation to acquisitions, primarily the PSN acquisition, totalled$964.8m (2010: $20.9m), deferred consideration paid in respect of prior periodacquisitions decreased to $14.6m (2010: $47.7m) and payments for capex andintangible assets increased to $104.4m (2010: $70.0m). We anticipate anincrease in capex and intangible spend in 2012 to around $130-$150m to includeexpenditure on GTS turbine test cells and business system investment.

The increase in tax paid in the year was due to higher profitability in the period, partially offset by a lower rate on continuing operations.

The increase in interest, dividend and other relates primarily to the purchase of shares for the employee benefit trust.

In February 2011, the Group extended (to April 2014) and renegotiated its $800m bilateral borrowing facilities which resulted in lower pricing.

Foreign exchange and constant currency reporting

The Group's results can be impacted by movements in foreign exchange rates,including the effect of retranslating the results of subsidiaries with variousfunctional currencies into US dollars at different exchange rates. Thecontinuing Group's 2010 EBITA of $218.7m retranslated at 2011 average exchangerates would have been $225.4m resulting in a constant currency growth rate of51.6% compared to a 56.2% increase in the reported numbers.

Pensions

The majority of the Group's pension arrangements are on a defined contributionbasis. The Group operates one UK defined benefit scheme which had 284 activemembers and 909 deferred, pensionable deferred or pensionable members at 31December 2011. At 31 December 2011 the scheme had a deficit of $45.8m (2010:$33.3m) before recognition of a deferred tax asset of $11.5m (2010: $9.0m). Inassessing the potential liabilities, judgment is required to determine theassumptions around future salary and pension increases, inflation, investmentreturns and member longevity. The increase from 2010 was due in part to lowerthan expected returns on scheme assets and partly to a reduction in thediscount rate used which is based on corporate bond yields. During the year aone off contribution of £5.0m ($8.0m) was made to the scheme.

The scheme is closed to new members and future benefits under the scheme are provided on a Career Average Revalued Earnings ("CARE") basis.

Full details of pension assets and liabilities are provided in note 29 to the Group financial statements.

AcquisitionsThe Group acquired 100% of the share capital of PSN on 20 April 2011 for atotal consideration of $684.9m, of which $569.9m was paid in cash and $115.0mof shares were issued. The Group repaid PSN's borrowings of $370.2m as part ofthe transaction. The acquisition of PSN advances Wood Group's strategy ofmaintaining a balance between oil & gas development and later cycle productionsupport, growing and maintaining our market leading positions, developing longterm customer relationships, extending services and broadening internationalpresence. PSN has been merged with Wood Group's Production Facilities businessto create Wood Group PSN. Wood Group PSN is a global leader in brownfieldproduction facilities support and is well positioned for growth across the oil& gas industry.The Group also made a number of other acquisitions during the year includingthe acquisition of Dar E&C, Pi-Consult and ISI in the Engineering division andIMS and GTE in the Wood Group GTS division. These other acquisitions providethe Group with access to new markets and strengthen the Group's capabilities incertain areas. The acquired companies will be in a position to access theGroup's wider client base and use the Group's existing relationships to furthergrow and develop their businesses.

Notes to the financial statements

for the year to 31 December 2011

General information

John Wood Group PLC, its subsidiaries and joint ventures provide services tothe oil and gas and power generation industries around the world. Details ofthe Group's activities during the year are detailed in the Operational Review.John Wood Group PLC is a public limited company, incorporated and domiciled inScotland and listed on the London Stock Exchange.

Accounting Policies

Basis of preparation

These financial statements have been prepared in accordance with IFRS and IFRICinterpretations adopted by the European Union (`EU') and with those parts ofthe Companies Act 2006 applicable to companies reporting under IFRS. The Groupfinancial statements have been prepared on a going concern basis under thehistorical cost convention as modified by the revaluation of financial assetsand liabilities at fair value through the income statement. Prior yearcomparatives have been restated to reflect the reclassification of discontinuedoperations and their presentation in the income statement.

Significant accounting policies

The Group's significant accounting policies adopted in the preparation of thesefinancial statements are set out below. These policies have been consistentlyapplied to all the years presented, unless otherwise stated.

Basis of consolidation

The Group financial statements are the result of the consolidation of thefinancial statements of the Group's subsidiary undertakings from the date ofacquisition or up until the date of divestment as appropriate. Subsidiaries areentities over which the Group has the power to govern the financial andoperating policies and generally accompanies a shareholding of more than onehalf of the voting rights. The Group's interests in joint ventures areaccounted for using proportional consolidation. Under this method the Groupincludes its share of each joint venture's income, expenses, assets,liabilities and cash flows on a line by line basis in the consolidatedfinancial statements. Transactions between Group subsidiaries are eliminatedand transactions between the Group and its joint ventures are eliminated to theextent of the Group's interest in the joint venture. All Group companies applythe Group's accounting policies and prepare financial statements to 31December.

Critical accounting judgments and estimates

The preparation of the financial statements requires the use of estimates andassumptions that affect the reported amounts of assets and liabilities at thedate of the financial statements and the reported amounts of revenue andexpenses during the year. These estimates are based on management's bestknowledge of the amount, event or actions and actual results ultimately maydiffer from those estimates. The estimates and assumptions that have asignificant risk of causing a material adjustment to the carrying amounts ofassets and liabilities are addressed below.

(a) Impairment of goodwill

The Group carries out impairment reviews whenever events or changes incircumstance indicate that the carrying value of goodwill may not berecoverable. In addition, the Group carries out an annual impairment review. Animpairment loss is recognised when the recoverable amount of goodwill is lessthan the carrying amount. The impairment tests are carried out by CGU ("CashGenerating Unit") and reflect the latest Group budgets. The budgets are basedon various assumptions relating to the Group's businesses including oil and gasprices, resource utilisation, foreign exchange rates, contract awards andcontract margins.

(b) Revenue recognition

Revenue on lump sum contracts for services, construction contracts and fixedprice long-term service agreements is recognised according to the stage ofcompletion reached in the contract by measuring the proportion of costsincurred for work performed to total estimated costs. Use of the percentage ofcompletion method requires the use of estimates in assessing the stage ofcompletion reached.

(c) Income taxes

The Group is subject to income taxes in numerous jurisdictions. Judgement is required in determining the

worldwide provision for income taxes. The Group recognises liabilities for anticipated tax issues based on estimates of whether additional taxes will be due. Where the final outcome of these matters is different from the

Notes to the financial statements

for the year to 31 December 2011

Accounting Policies (continued)

amounts that were initially recorded, such differences will impact the current and deferred income tax assets and liabilities in the period in which such determination is made.

Functional currency

The Group's earnings stream is primarily US dollars and the principal functional currency is the US dollar, being the most representative currency of the Group. The Group's financial statements are therefore prepared in US dollars.

The following exchange rates have been used in the preparation of theseaccounts: 2011 2010 Average rate £1 = $ 1.6041 1.5459 Closing rate £1 = $ 1.5541 1.5657Foreign currenciesIncome statements of entities whose functional currency is not the US dollarare translated into US dollars at average rates of exchange for the period andassets and liabilities are translated into US dollars at the rates of exchangeruling at the balance sheet date. Exchange differences arising on translationof net assets in such entities held at the beginning of the year, together withthose differences resulting from the restatement of profits and losses fromaverage to year end rates, are taken to the currency translation reserve.In each individual entity, transactions in overseas currencies are translatedinto the relevant functional currency at the exchange rates ruling at the dateof the transaction. Where more than one exchange rate is available, theappropriate rate at which assets can be readily realised and liabilities can beextinguished is used. Monetary assets and liabilities denominated in foreigncurrencies are retranslated at the exchange rates ruling at the balance sheetdate. Any exchange differences are taken to the income statement.

Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and translated at the exchange rate ruling at the balance sheet date.

The directors consider it appropriate to record sterling denominated equity share capital in the accounts of John Wood Group PLC at the exchange rate ruling on the date it was raised.

Revenue recognition

Revenue comprises the fair value of the consideration received or receivablefor the sale of goods and services in the ordinary course of the Group'sactivities. Revenue is recognised only when it is probable that the economicbenefits associated with a transaction will flow to the Group and the amount ofrevenue can be measured reliably. Revenue from services is recognised as theservices are rendered, including where they are based on contractual rates perman hour in respect of multi-year service contracts. Incentive performancerevenue is recognised upon completion of agreed objectives. Revenue fromproduct sales is recognised when the significant risks and rewards of ownershiphave been transferred to the buyer, which is normally upon delivery of productsand customer acceptance, if any. Revenue is stated net of sales taxes (such asVAT) and discounts.Revenue on lump sum contracts for services, construction contracts and fixedprice long-term service agreements is recognised according to the stage ofcompletion reached in the contract by measuring the proportion of costsincurred for work performed to total estimated costs. An estimate of the profitattributable to work completed is recognised once the outcome of the contractcan be estimated reliably. Expected losses are recognised in full as soon aslosses are probable. The net amount of costs incurred to date plus recognisedprofits less the sum of recognised losses and progress billings is disclosed astrade receivables/trade payables.

Exceptional items

Exceptional items are those significant items which are separately disclosed by virtue of their size or incidence to

enable a full understanding of the Group's financial performance. Transactionswhich may give rise to exceptional items include gains and losses on divestmentof businesses, write downs or impairments of assets including goodwill,restructuring costs or provisions, litigation settlements, acquisition costsand one-off gains and losses arising from currency devaluations.

Finance expense/income

Interest income and expense is recorded in the income statement in the periodto which it relates. Arrangement fees in respect of the Group's borrowingfacilities are amortised over the period to which the facility relates.Interest relating to the discounting of deferred and contingent considerationliabilities is recorded as finance expense.

Dividends

Dividends to the Group's shareholders are recognised as a liability in the period in which the dividends are approved by shareholders.

Goodwill

The Group uses the purchase method of accounting to account for acquisitions.Goodwill represents the excess of the cost of an acquisition over the fairvalue of the net assets acquired. Goodwill is carried at cost less accumulatedimpairment losses. Goodwill is not amortised.Acquisition costs relating to business combinations prior to 31 December 2009were treated as part of the cost of the acquisition and capitalised asgoodwill. In accordance with IFRS 3 (revised), acquisition costs relating tobusiness combinations completed on or after 1 January 2010 are expensed in

theincome statement.Intangible assetsIntangible assets are carried at cost less accumulated amortisation. Intangibleassets are recognised if it is probable that there will be future economicbenefits attributable to the asset, the cost of the asset can be measuredreliably, the asset is separately identifiable and there is control over theuse of the asset. Where the Group acquires a business, intangible assets onacquisition such as customer contracts are identified and evaluated todetermine the carrying value on the acquisition balance sheet. Intangibleassets are amortised over their estimated useful lives, as follows:

Software and development costs 3-5 years

Intangible assets on acquisition 3-10 years

Property plant and equipment

Property plant and equipment (PP&E) is stated at cost less accumulated depreciation and impairment. No depreciation is charged with respect to freehold land and assets in the course of construction. Transfers from PP&E to current assets are undertaken at the lower of cost and net realisable value.

Depreciation is calculated using the straight line method over the following estimated useful lives of the assets:

Freehold and long leasehold buildings 25-50 years

Short leasehold buildings period of lease

Plant and equipment 3-10 years

When estimating the useful life of an asset group, the principal factors theGroup takes into account are the durability of the assets, the intensity atwhich the assets are expected to be used and the expected rate of technologicaldevelopments.

Accounting Policies (continued)

Impairment

The Group performs impairment reviews in respect of PP&E and other intangibleassets whenever events or changes in circumstance indicate that the carryingamount may not be recoverable. In addition, the Group carries out annualimpairment reviews in respect of goodwill. An impairment loss is recognisedwhen the recoverable amount of an asset, which is the higher of the asset'sfair value less costs to sell and its value in use, is less than its carryingamount.For the purposes of impairment testing, goodwill is allocated to theappropriate cash generating unit ("CGU"). The CGUs are aligned to the structurethe Group uses to manage its business. Cash flows are discounted in determiningthe value in use.InventoriesInventories, which include materials, work in progress and finished goods andgoods for resale, are stated at the lower of cost and net realisable value.Service based companies' inventories consist of spare parts and otherconsumables. Serialised parts are costed using the specific identificationmethod and other materials are generally costed using the first in, first outmethod. Product based companies determine cost by weighted average cost methodsusing standard costing to gather material, labour and overhead costs. Thesecosts are adjusted, where appropriate, to correlate closely the standard coststo the actual costs incurred based on variance analysis.

Net realisable value is the estimated selling price in the ordinary course of business, less the estimated costs of completion and estimated selling expenses. Allowance is made for obsolete and slow-moving items, based upon annual usage.

Cash and cash equivalents

Cash and cash equivalents include cash in hand and other short-term bank deposits with maturities of three months or less and bank overdrafts where there is a right of set-off. Bank overdrafts are included within borrowings in current liabilities where there is no right of set-off.

Trade receivables

Trade receivables are recognised initially at fair value and subsequentlymeasured at amortised cost using the effective interest method, less provisionfor impairment. A provision for impairment of trade receivables is establishedwhen there is objective evidence that the Group will not be able to collect allamounts due according to the original terms of the receivables. The amount ofthe provision is the difference between the asset's carrying amount and thepresent value of estimated future cash flows, discounted at the effectiveinterest rate. The provision is determined by reference to previous experienceof recoverability for receivables in each market in which the Group operates.

Trade payables

Trade payables are recognised initially at fair value and subsequently measured at amortised cost.

Borrowings

Borrowings are recognised initially at fair value, net of transaction costs incurred. Borrowings are subsequently stated at amortised cost.

Deferred and contingent consideration

Where it is probable that deferred or contingent consideration is payable onthe acquisition of a business based on an earn out arrangement, an estimate ofthe amount payable is made at the date of acquisition and reviewed regularlythereafter, with any change in the estimated liability being reflected in theincome statement. Changes in the estimated liability in respect of acquisitionscompleted before 31 December 2009 are reflected in goodwill. Changes in theestimated liability in respect of acquisitions completed after 31 December 2009are expensed in the income statement. Where deferred consideration is payableafter more than one year the estimated liability is discounted using anappropriate rate of interest.

Notes to the financial statements

for the year to 31 December 2011

Accounting Policies (continued)

Taxation

The tax charge represents the sum of tax currently payable and deferred tax.Tax currently payable is based on the taxable profit for the year. Taxableprofit differs from the profit reported in the income statement due to itemsthat are not taxable or deductible in any period and also due to items that aretaxable or deductible in a different period. The Group's liability for currenttax is calculated using tax rates enacted or substantively enacted at thebalance sheet date.Deferred tax is provided, using the full liability method, on temporarydifferences arising between the tax bases of assets and liabilities and theircarrying amounts in the consolidated financial statements. The principaltemporary differences arise from depreciation on PP&E, tax losses carriedforward and, in relation to acquisitions, the difference between the fairvalues of the net assets acquired and their tax base. Tax rates enacted, orsubstantially enacted, at the balance sheet date are used to determine deferredtax.

Deferred tax assets are recognised to the extent that it is probable that future taxable profits will be available against which the temporary differences can be utilised.

Accounting for derivative financial instruments and hedging activities

Derivatives are initially recognised at fair value on the date the contract isentered into and are subsequently remeasured at their fair value. The method ofrecognising the resulting gain or loss depends on whether the derivative isdesignated as a hedging instrument, and if so, the nature of the item beinghedged. The Group designates certain derivatives as either: (1) hedges of thefair value of recognised assets or liabilities or a firm commitment (fair valuehedge); (2) hedges of highly probable forecast transactions (cash flow hedge);or (3) hedges of net investments in foreign operations (net investment hedge).Where hedging is to be undertaken, the Group documents the relationship betweenthe hedging instrument and the hedged item at the inception of the transaction,as well as its risk management objective and strategy for undertaking the hedgetransaction. The Group also documents its assessment, both at hedge inceptionand on an ongoing basis, of whether the derivatives that are used in hedgingtransactions are highly effective in offsetting changes in fair values or cashflows of the hedged items. The Group performs effectiveness testing on aquarterly basis.

a. Fair value hedge

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in administrative expenses in the income statement, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk.

b. Cash flow hedge

The effective portion of changes in the fair value of derivatives that aredesignated and qualify as cash flow hedges is recognised in the hedging reservein equity. The gain or loss relating to the ineffective portion is recognisedimmediately in administrative expenses in the income statement. Amountsaccumulated in equity are recycled through the income statement in periods whenthe hedged item affects profit or loss.When a hedging instrument expires or is sold, or when a hedge no longer meetsthe criteria for hedge accounting, any cumulative gain or loss existing inequity at that time remains in equity and is recognised when the forecasttransaction is ultimately recognised in the income statement. When a forecasttransaction is no longer expected to occur, the cumulative gain or loss thatwas reported in equity is immediately transferred to the income statement.

c. Net investment hedge

Hedges of net investments in foreign operations are accounted for similarly tocash flow hedges. Any gain or loss on the hedging instrument relating to theeffective portion of the hedge is recognised in the currency translationreserve in equity; the gain or loss relating to the ineffective portion isrecognised immediately in administrative expenses in the income statement.Gains and losses accumulated in equity are included in the income statementwhen the foreign operation is disposed of.

Notes to the financial statements

for the year to 31 December 2011

Accounting Policies (continued)

d. Derivatives that are not designated as hedges

Certain derivatives, whilst providing effective economic hedges are not designated as hedges. Changes in the fair value of any derivative instruments that are not designated for hedge accounting are recognised immediately in administrative expenses in the income statement.

Fair value estimation

The fair value of interest rate swaps is calculated as the present value oftheir estimated future cash flows. The fair value of forward foreign exchangecontracts is determined using forward foreign exchange market rates at thebalance sheet date. The fair values of all derivative financial instruments areobtained from valuations provided by financial institutions.

The carrying values of trade receivables and payables approximate to their fair values.

The fair value of financial liabilities is estimated by discounting the futurecontractual cash flows at the current market interest rate that is available tothe Group for similar financial instruments.

Operating leases

As lessee

Payments made under operating leases are charged to the income statement on astraight line basis over the period of the lease. Benefits received andreceivable as an incentive to enter into an operating lease are also spread ona straight line basis over the period of lease.

As lessor

Operating lease rental income arising from leased assets is recognised in the income statement on a straight line basis over the period of the lease.

Retirement benefit liabilities

The Group operates a defined benefit scheme and a number of definedcontribution schemes. The liability recognised in respect of the definedbenefit scheme represents the present value of the defined benefit obligationsless the fair value of the scheme assets. The assets of this scheme are held inseparate trustee administered funds.The defined benefit scheme's assets are measured using market values. Pensionscheme liabilities are measured annually by an independent actuary using theprojected unit method and discounted at the current rate of return on a highquality corporate bond of equivalent term and currency to the liability. Theincrease in the present value of the liabilities of the Group's defined benefitscheme expected to arise from employee service in the period is charged tooperating profit. The expected return on the scheme assets and the increaseduring the period in the present value of the scheme's liabilities arising fromthe passage of time are included in finance income/expense. Actuarial gains andlosses are recognised in the statement of comprehensive income in full in theperiod in which they occur. The defined benefit scheme's net assets or netliabilities are recognised in full and presented on the face of the balancesheet.

The Group's contributions to defined contribution schemes are charged to the income statement in the period to which the contributions relate.

Notes to the financial statements

for the year to 31 December 2011

Accounting Policies (continued)

Provisions

Provision is made for the estimated liability on all products and servicesstill under warranty, including claims already received, based on pastexperience. Other provisions are recognised where the Group is deemed to have alegal or constructive obligation, it is probable that a transfer of economicbenefits will be required to settle the obligation, and a reliable estimate ofthe obligation can be made. Where amounts provided are payable after more thanone year the estimated liability is discounted using an appropriate rate ofinterest.

Share based charges relating to employee share schemes

The Group has a number of employee share schemes:-

i. Share options granted under Executive Share Option Schemes (`ESOS') are

granted at market value. A charge is booked to the income statement as an

employee benefit expense for the fair value of share options expected to be

exercised, accrued over the vesting period. The corresponding credit is

taken to retained earnings. The fair value is calculated using an option

pricing model.

ii. Share options granted under the Long Term Retention Plan (`LTRP') are

granted at par value. The charge to the income statement for LTRP shares is

also calculated using an option pricing model and, as with ESOS grants, the

fair value of the share options expected to be exercised is accrued over

the vesting period. The corresponding credit is also taken to retained

earnings.

iii. The Group has a Long Term Incentive Plan (`LTIP') for executive directors

and certain senior executives. Participants are awarded shares dependent on

the achievement of performance targets. The charge to the income statement

for shares awarded under the LTIP is based on the fair value of those

shares at the grant date, spread over the vesting period. The corresponding

credit is taken to retained earnings. For those awards that have a market

related performance measure, the fair value of the market related element

is calculated using a Monte Carlo simulation model.

iv. The Group has a Long Term Cash Incentive Plan (`LTCIP') for senior

management. Particpants are paid a cash bonus dependent on the achievement

of performance targets. The charge to the income statement is based on the

fair value of the awards at the balance sheet date. The charge is spread

over the vesting period with the corresponding credit being recorded in

liabilities.

Proceeds received on the exercise of share options are credited to share capital and share premium.

Share capital

John Wood Group PLC has one class of ordinary shares and these are classifiedas equity. Dividends on ordinary shares are not recognised as a liability orcharged to equity until they have been approved by shareholders.The Group is deemed to have control of the assets, liabilities, income andcosts of its employee share trusts, therefore they have been consolidated inthe financial statements of the Group. Shares acquired by and disposed of bythe employee share trusts are recorded at cost. The cost of shares held by theemployee share trusts is deducted from equity.

Segmental reporting

The Group has determined that its operating segments are based on managementreports reviewed by the Chief Operating Decision Maker (`CODM'), the Group'sChief Executive. Following the acquisition of PSN and the divestment of theWell Support division the Group's reportable segments are now Engineering, WoodGroup PSN and Wood Group GTS. Management considers these segments to be themost appropriate in light of the change in the structure of the Group.Comparative figures have been restated to reflect the change to operatingsegments.

Notes to the financial statements

for the year to 31 December 2011

Accounting Policies (continued)

The CODM measures the operating performance of these segments using `EBITA' (Earnings before interest, tax and amortisation). Operating segments are reported in a manner consistent with the internal management reports provided to the CODM who is responsible for allocating resources and assessing performance of the operating segments.

Engineering offers a wide range of services to the upstream, subsea andpipelines, downstream and industrial, and clean energy sectors. These includeconceptual studies, engineering, project and construction management (`EPCM')and control system upgrades.

Wood Group PSN offers life of field support to producing assets through brownfield engineering and modifications, production enhancement, operations and management (including UK dutyholder services), training, maintenance management and abandonment services.

Wood Group GTS is an independent provider of rotating equipment services and solutions for clients in the power, oil and gas and clean energy markets. Aftermarket maintenance activities include facility operations and

maintenance, repair and overhaul of gas, wind and steam turbines, pumps and other high speed rotating equipment. The Power Solutions business includes power plant engineering, procurement and construction and construction management services to the owners of power generation facilities.

Disclosure of impact of new and future accounting standards

New and amended standards adopted by the Group

There are no IFRSs or IFRIC interpretations that are effective for the firsttime for the financial year beginning on 1 January 2011 that have a materialimpact on the Group.

New standards, amendments and interpretations issued but not effective for the financial year beginning 1 January 2011 and not early adopted

* IAS 19 `Employee benefits' (amended standard) * IFRS 9 `Financial instruments' * IFRS 10 `Consolidated financial statements' * IFRS 11 `Joint arrangements' * IFRS 12 `Disclosures of interests in other entities' * IFRS 13 `Fair value measurement'

The Group has yet to assess the full impact of these new standards and amendments but does not expect them to have a material impact on the financial statements.

Acquisition costs of $12.0m were expensed in the year, including $9.8m relatingto the purchase of PSN, $1.6m in respect of acquisitions in the Wood Group GTSdivision and $0.6m in respect of Engineering acquisitions. The cash impact ofacquisition costs in the period was $9.6m. In 2010, $6.6m of costs, mainlyrelating to PSN, were expensed.Integration and restructuring charges of $84.2m have been expensed in theyear. The majority of these costs, $79.6m, resulted from the integration ofthe PSN acquisition into the Wood Group PSN division, and decisions made towithdraw from certain geographical markets in the Wood Group PSN and Wood GroupGTS divisions. Further restructuring costs of $4.6m have been recorded in theEngineering division. The cash impact of the integration and restructuringcosts in the year was $6.8m. The integration and restructuring charge in 2010related to the closure of a US repair facility in the Wood Group GTS division.As a result of the political disruption earlier in 2011 the Group recorded anexceptional charge of $13.0m in relation to some overdue Libyan receivables.Due to continued doubts about their recoverability, the outstanding balance hasbeen provided in full.Goodwill impairment of $45.1m was charged to the income statement in respect ofa Wood Group GTS power related business. The goodwill has been written downbased on the Group's estimate of current value. A further goodwill impairmentcharge of $1.1m was made in relation to the Wood Group PSN restructuringreferred to above. The 2010 impairment charge related to the closure of the USrepair facility in the Wood Group GTS division.

A tax credit of $26.7m was recorded in relation to exceptional items on continuing operations in the year.

Included in exceptional items from discontinued operations was the gain ondivestment of Well Support of $2,305.7m (note 27), and a charge of $12.0m inrelation to the write down of the assets of the aero engine overhaul businessto their anticipated selling price. The divestment is expected to be completedin the first half of 2012.

In accordance with IAS 36 `Impairment of assets', goodwill was tested forimpairment during the year. The impairment tests were carried out on a CashGenerating Unit (`CGU') basis using the 2012-13 budgets. Cash flows for 2014-16are assumed to grow at a rate of 5% per annum and subsequent cash flows havebeen assumed to grow at 3% per annum for a further 15 years reflecting expectedlong-term growth rates in the countries in which the Group operates. Managementbelieve that 5% is an appropriate growth rate to use for the markets in whichthe Group operates. Details of other key assumptions used are included incritical accounting judgements and estimates in the Accounting Policies. Intotal, a 20 year period has been used for the impairment tests reflecting theexpected long-term growth in the market. The cash flows have been discountedusing a pre-tax discount rate of 10%.

8 Goodwill and other intangible assets (continued)

The value in use has been compared to the net book value of goodwill for eachCGU to assess whether an impairment write down is required. $46.2m of goodwillhas been impaired during the year. See note 4 for further details.A sensitivity analysis has been performed on the basis that the expectedlong-term growth rate falls to 2% and that the pre-tax discount rate increasesto 12% in order to assess the impact of reasonable possible changes to theassumptions used in the impairment review. This analysis did not identify anyfurther CGUs requiring to be impaired. The carrying amounts of goodwill bydivision at 31 December 2011 are: Engineering $386.9m (2010 : $346.3m), WoodGroup PSN $928.7m (2010 : $122.2m), Wood Group GTS $95.1m (2010 : $116.5m) andWell Support $nil (2010 : $31.8m). The carrying amounts of goodwillattributable to the principal CGUs within the Engineering division are WoodGroup Mustang $199.3m, IMV $126.8m and Wood Group Kenny $55.5m. The carryingamounts of goodwill attributable to the principal CGUs within Wood Group PSNare PSN $801.0m, US Onshore $56.3m and WG PSN Services $44.7m. The carryingamounts of goodwill attributable to the principal CGUs within the Wood GroupGTS division are Equipment and Project Solutions $37.7m, Power Plant Services$18.8m and Oil & Gas and Industrial Services $17.1m.

Intangibles arising on acquisition includes the valuation of customer contracts and customer relationships recognised on business combinations.

Development costs with a net book value of $22.9m (2010 : $11.7m) are internally generated intangible assets.

17 Financial instrumentsThe Group's activities give rise to a variety of financial risks: market risk(including foreign exchange risk and cash flow interest rate risk), credit riskand liquidity risk. The Group's overall risk management strategy is to hedgeexposures wherever practicable in order to minimise any potential adverseimpact on the Group's financial performance.Risk management is carried out by the Group Treasury department in line withthe Group's Treasury policies. Group Treasury, together with the Group'sbusiness units identify, evaluate and where appropriate, hedge financial risks.The Group's Treasury policies cover specific areas, such as foreign exchangerisk, interest rate risk, use of derivative financial instruments andinvestment of excess cash.Where the Board considers that a material element of the Group's profits andnet assets are exposed to a country in which there is significant geo-politicaluncertainty a strategy is agreed to ensure that the risk is minimised.

17 Financial instruments (continued)

(a) Market risk

(i) Foreign exchange risk

The Group is exposed to foreign exchange risk arising from various currencies.The Group has a number of subsidiary companies whose revenue and expenses aredenominated in currencies other than the US dollar. Where practical, the Grouphedges part of its net investment in non-US dollar subsidiaries by usingforeign currency bank loans. Other strategies, including the payment ofdividends, are used to minimise the amount of net assets exposed to foreigncurrency revaluation.Some of the revenues of the Group's businesses are to customers in overseaslocations. Where possible, the Group's policy is to eliminate all significantcurrency exposures on revenues at the time of the transaction by usingfinancial instruments such as forward currency contracts. Changes in theforward contract fair values are booked through the income statement, exceptwhere hedge accounting is used in which case the change in fair value isrecorded in equity.

The Group carefully monitors the economic and political situation in the countries in which it operates to ensure appropriate action is taken to minimise any foreign currency exposure.

The Group's main foreign exchange risk relates to movements in the sterling/USdollar exchange rate. Movements in the sterling/US dollar rate impact thetranslation of sterling profit earned in the UK and the translation of sterlingdenominated net assets.If the average sterling/US dollar rate had been 10% higher or lower during 2011(2010:10%), post-tax profit for the year would have been $10.6m higher or lower(2010: $6.9m). If the closing sterling/US dollar rate was 10% higher or lowerat 31 December 2011 (2010:10%), exchange differences in equity would have been$28.8m (2010: $18.3m) higher or lower respectively. 10% has been used in thesecalculations as it represents a reasonable possible change in the sterling/USdollar exchange rate.(ii) Interest rate risk

The Group finances its operations through a mixture of retained profits andbank borrowings. The Group borrows in the desired currencies at floating ratesof interest and then uses interest rate swaps into fixed rates to generate thedesired interest profile and to manage the Group's exposure to interest ratefluctuations. The Group's long-term policy is to maintain approximately 50% ofits borrowings at fixed rates of interest. At 31 December 2011, 47% (2010 :57%) of the Group's borrowings were at fixed rates after taking account ofinterest rate swaps.The Group is also exposed to interest rate risk on cash held on deposit. TheGroup's policy is to maximise the return on cash deposits whilst ensuring thatcash is deposited with a financial institution with a credit rating of `A' orbetter, where possible. If average interest rates had been 1% higher or lowerduring 2011 (2010:1%), post-tax profit for the year would have been $1.3mhigher or lower respectively (2010: $1.2m). 1% has been used in thiscalculation as it represents a reasonable possible change in interest rates.

(iii) Price risk

The Group is not exposed to any significant price risk in relation to its financial instruments.

17 Financial instruments (continued)

(b) Credit risk

The Group's credit risk primarily relates to its trade receivables. The Group'soperations comprise three divisions, Engineering, Wood Group PSN and Wood GroupGTS each made up of a number of businesses. Responsibility for managing creditrisks lies within the businesses with support being provided by Group anddivisional management where appropriate.A customer evaluation is typically obtained from an appropriate credit ratingagency. Where required, appropriate trade finance instruments such as lettersof credit, bonds, guarantees and credit insurance will be used to manage creditrisk.The Group's major customers are typically large companies which have strongcredit ratings assigned by international credit rating agencies. Where acustomer does not have sufficiently strong credit ratings, alternative forms ofsecurity such as the trade finance instruments referred to above may beobtained. The Group has a broad customer base and management believe that nofurther credit risk provision is required in excess of the provision forimpairment of trade receivables.Management review trade receivables across the Group based on receivable dayscalculations to assess performance. There is significant management focus onreceivables that are overdue. A table showing trade receivables and receivabledays by division is provided in note 12. Receivable days calculations are notprovided on non-trade receivables as management do not believe that thisinformation is a relevant metric.The Group also has credit risk in relation to cash held on deposit. The Group'spolicy is to deposit cash at institutions with a credit rating of `A' or betterwhere possible. 74% of cash held on deposit at 31 December 2011 (2010 : 100%)was held with such institutions.

(c) Liquidity risk

With regard to liquidity, the Group's main priority is to ensure continuity offunding. At 31 December 2011, 91% (2010 : 94%) of the Group's borrowingfacilities (excluding joint ventures) were due to mature in more than one year.Based on the current outlook the Group has sufficient funding in place to meetits future obligations.(d) Capital risk

The Group seeks to maintain an optimal capital structure. The Group monitors its capital structure on the basis of its gearing ratio, interest cover and when applicable, the ratio of net debt to EBITDA.

Gearing is calculated by dividing net debt by equity attributable to owners of the parent. Gearing at 31 December 2011 was 0.2% (2010: 1.1%).

Interest cover is calculated by dividing EBITA from continuing operations by net finance expense from continuing operations before exceptional items. Interest cover for the year to 31 December 2011 was 38.8 times (2010: 6.5 times).

The ratio of net debt to continuing EBITDA at 31 December 2011 was 0.01 times (2010: 0.04 times).

Fair value of non-derivative financial assets and financial liabilities

The fair value of short-term borrowings, trade and other payables, trade andother receivables, short-term deposits and cash at bank and in handapproximates to the carrying amount because of the short maturity of interestrates in respect of these instruments. Drawdowns under long-term bankfacilities are for periods of three months or less and as a result, book valueand fair value are considered to be the same.

Details of derivative financial instruments are not disclosed in the financial statements as they are not material.

They are based on previousclaims history and it is expected that most of the costs in respect of theseprovisions will be incurred over the next two years.

Other provisions

At 31 December 2011, other provisions of $75.6m (2010 : $20.5m) have been recognised. This amount includes provisions for future losses on onerous contracts, a provision for non-recoverable indirect taxes and provisions relating to the divestment of businesses. It is expected that any payment required in respect of these provisions would be made within the next two years.

19 Deferred tax (continued)

A deferred tax charge of $4.2m (2010: credit $8.0m) relating to discontinuedactivities is included within the credit to the income statement shown in theabove table.

No deferred tax is recognised on the unremitted earnings of overseas subsidiaries and joint ventures. As these earnings are continually reinvested by the Group, no tax is expected to be payable on them in the foreseeable future.

The Group has unrecognised tax losses of $147.6m (2010: $56.2m) to carry forward against future taxable income.

The Group currently has four share schemes that give rise to share based charges. These are the Executive Share Option Scheme (`ESOS'), the Long Term Retention Plan (`LTRP'), the Long Term Incentive Plan (`LTIP') and the Long Term Cash Incentive Plan (`LTCIP'). Further details of these schemes is provided in the Directors' Remuneration Report and in note 21.

The charge to operating profit in 2011 for these schemes amounted to $19.2m(2010 : $16.7m). $16.0m of the total charge is credited to retained earningsand $3.2m, relating to the LTCIP is included in other long term liabilities asthe LTCIP is a cash settled scheme. The total credit to retained earningsrelating to share based charges in 2011 is $9.7m which comprises the $16.0mmentioned above, $3.6m of accelerated charges relating to the Well Supportdisposal that have been recorded against the gain on divestment less the fairvalue of payments made to Well Support employees on the disposal amounting to$9.9m.

The assumptions made in arriving at the charge for each scheme are detailed below:

ESOS and LTRP

At 31 December 2011 there were 1,158 employees (2010 : 1,138) participating inthese schemes. For the purposes of calculating the fair value of the shareoptions, a Black-Scholes option pricing model has been used. Based on pastexperience, it has been assumed that options will be exercised, on average, sixmonths after the earliest exercise date, which is four years after grant date,and there will be a lapse rate of between 15% and 20%. The share pricevolatility used in the calculation of 35%-40% is based on the actual volatilityof the Group's shares since IPO as well as that of comparable companies. Therisk free rate of return of 1.1%-5.2% is based on the implied yield availableon zero coupon gilts with a term remaining equal to the expected lifetime ofthe options at the date of grant. A dividend yield of 1.0%-2.0% has been usedin the calculations.The fair value of options granted under the ESOS during the year was £1.62(2010 : £1.16). The fair value of options granted under the LTRP during theyear ranged from £4.94 to £6.38 (2010 : £2.79 to £3.57). The weighted averageremaining contractual life of share options at 31 December 2011 is 5.7 years(2010: 5.5 years).LTIPThe share based charge for the LTIP was calculated using a fair value of £4.12for the first cycle, £1.81 for the second cycle, £3.01 for the third cycle and£5.10 for the fourth cycle. The charge for market related performance targetshas been calculated using a Monte Carlo simulation model taking account ofshare price volatility against peer group companies, risk free rate of return,dividend yield and the expected lifetime of the award.

LTCIP

The share based charge for the LTCIP was calculated using a fair value of £6.18. The fair value is calculated using a Black-Scholes option pricing modelusing similar assumptions to those used for ESOS and LTRP above.

29 Retirement benefit liabilities

One of the Group's pension schemes in the UK, the John Wood Group PLC Retirement Benefits Scheme, is a defined benefit scheme, which is contracted out of the State Scheme. The assets of the scheme are held separately from those of the Group, being invested with independent investment companies in trustee administered funds.

The most recent actuarial valuation of the scheme was carried out at 5 April 2010 by a professionally qualified actuary.

The principal assumptions made by the actuaries at the balance sheet date were: 2011 2010 % %

Rate of increase in pensionable salaries 4.90

5.30

Rate of increase in pensions in payment and deferred 2.90

3.30pensions Discount rate 4.80 5.40

Expected return on scheme assets 7.00

7.24

The expected return on scheme assets is based on market expectation at the beginning of the period for returns over the entire life of the benefit obligation.

At 31 December 2011 the actuary has determined pension liabilities by referenceto a standard actuarial mortality table which considered UK wide mortality datarelevant to the Group's pension scheme. Those observed mortality rates havebeen projected to improve at a specific rate into the future to allow forestablished trends and expectations in line with normal actuarial practice.Specifically, the actuarial table used was PXA00 and improvements were in linewith the long cohort approach with an annual underpin of 1% p.a.

The amounts recognised in the balance sheet are determined as follows:

2011 2010 $m $m Present value of funded obligations (206.7) (188.3) Fair value of scheme assets 160.9 155.0 Net liabilities (45.8) (33.3)The major categories of scheme assets as a percentage of total scheme assetsare as follows: 2011 2010 % % Equity securities 83.4 84.4 Corporate bonds 7.7 9.5 Gilts 8.6 5.1 Cash 0.3 1.0
