  • 16. 14 National Grid Gas plc Annual Report and Accounts 2011/12Principal risk factorsOur risk management process has identified the following principal risk factors that could have a material adverse effect on ourbusiness, financial condition, results of operations and reputation, as well as the value and liquidity of our securities. Whenappropriate, we implement processes, procedures and controls to minimise the likelihood of a risk occurring or the potential impact if itdoes occur. It is not possible to eliminate a risk and even where a response is in place and effective, a risk may still occur.Risk factor Details of the risk and examples of our responsesHarmful activities Aspects of our activities are potentially hazardous or could damage the environment. We are exposed to costs and liabilities from our operations and properties, including those inherited from predecessor bodies, or formerly owned by us, and sites used for the disposal of our waste. We are increasingly subject to regulation in relation to climate change and are affected by requirements to reduce our own carbon emissions as well as reduction in energy use by our customers. If the legal requirements become more onerous or our regulatory framework changes, then we may not be able to recover all the costs of complying with these laws and regulations. Our responses We have implemented safety and occupational health plans, programmes and procedures that are aimed at continuous improvements in safety performance. We continue to focus on process safety, which ensures that at all stages of the asset life cycle key safety considerations are taken into account. This includes the process and procedures that govern the development and design of the assets, the competence of the staff who will build, operate and maintain the assets and the quality of the materials used to construct them. During the life cycle of our assets we develop risk assessments and method statements to ensure the safety of those working on equipment, the public and the operational performance of the system are not compromised. More information on our safety initiatives can be found on page 8. We are working to reduce our greenhouse gas (GHG) emissions and promote their global reduction through support of mandatory reporting legislation. Our approach to GHG emission reductions is discussed on page 9. We maintain robust investigation and remediation programmes to clean up wastes. We have engineered controls in place to minimise or mitigate releases to the environment during remediation activities, including containment, alarms, spill response contracts and equipment.Infrastructure and IT We may suffer a major network failure or interruption, or may not be able to carry out critical non-networksystems operations. This could cause us to fail to meet agreed standards of service, incentive and reliability targets, or be in breach of a licence, approval, regulatory requirement or contractual obligation, and even incidents that do not amount to a breach could result in adverse regulatory and financial consequences, as well as harming our reputation. Our responses Routine maintenance is supported by a risk-based asset replacement strategy. A global safety management process was initiated last year to reduce the likelihood of a major accident hazard. It focuses on industry best practice risk assessment techniques, which may proactively identify opportunities to improve asset integrity. We have robust demand forecasting processes and scenario analysis in place informed by broad consultation. We use this information to plan our future development activity to ensure our network has the capacity to meet customer demands and also make this analysis available to stakeholders to inform their actions. UK Future Energy Scenarios, available on National Grid’s website, gives more information. We use industry best practices as part of our cyber security policies, processes and technologies and continually invest in cyber strategies that are commensurate with the changing nature of the security landscape.
  • 17. National Grid Gas plc Annual Report and Accounts 2011/12 15Risk factor Details of the risk and examples of our responsesLaw and regulation Changes in law or regulation or decisions by governmental bodies or regulators could materially adversely affect us. See pages 4 to 5 which explain our regulatory environment in detail. Our responses We actively participate in regulatory development and implementation to help shape favourable outcomes for National Grid’s shareholders and the industry. We are working closely with Ofgem as they review our business plan submissions for RIIO-T1 and RIIO- GD1. Initial feedback has been favourable but final decisions are not due until later in the year and our engagement in this process will continue. National Grid recently opened an office in Brussels to establish a stronger and more visible presence with EU institutions and policy makers. We will inform the evolving discussion around European Network Codes, CO2 reduction targets beyond 2020 and more.Cost escalation Changes in foreign currency rates or interest rates or could materially impact earnings or our financial condition. Our results and net debt position may be affected because a significant proportion of our borrowings, and derivative financial instruments are affected by changes in interest rates and exchange rates, in particular the euro to sterling and the dollar to sterling exchange rates. Furthermore, our cash flow may be materially affected as a result of settling hedging arrangements entered into to manage our exchange rate and interest rate exposure, or by cash collateral movements relating to derivative market values. Operating costs may increase faster than revenues. While income under our price controls is linked to the RPI, our operating costs may increase at a faster rate than RPI. The majority of our employees are members of a defined benefit pension scheme where the scheme assets are held independently of our own financial resources. If the scheme does not perform as currently expected, then we may be required by National Grid to make additional contributions to the pension scheme which, to the extent they are not recoverable under our price controls, could adversely affect our results and financial condition. Our responses National Grid’s treasury function manages our financial risks, including foreign currency and interest rate, to within acceptable boundaries and under policies and guidelines approved by the Finance Committees of National Grid and our Board. The treasury function is not operated as a profit centre. Debt and treasury positions are managed in a non-speculative manner with all transactions in financial instruments or products matched to an underlying current or anticipated business requirement. Foreign currency risk: Transaction risk is managed by hedging contractually committed foreign exchange transactions over a prescribed minimum size. Where foreign currency cash flow forecasts are uncertain and a judgement has to be made, we hedge a proportion based on the likelihood of them occurring, aiming to hedge substantially all such cash flows without over hedging. A hedge may be put in place where a foreign currency exposure is likely to occur, but where contracts have yet to be signed. Cover usually involves forward sale or purchase of foreign currencies and must always relate to forecast underlying operational cash flows. Interest rate risk: Interest rate risk is managed by seeking to minimise total financing costs (interest costs and changes in the market value of debt) subject to constraints. We do this by using fixed- and floating-rate debt and derivative financial instruments, including interest rate swaps, swaptions and forward rate agreements. We maintain a portion of our debt portfolio as inflation linked bonds. This provides a partial economic offset to the inflation risk associated with our UK inflation linked revenues. We measure the effectiveness of our interest rate risk management by comparing the actual total financing costs with those of a passively managed benchmark portfolio. This is regularly monitored by the Finance
  • 18. 16 National Grid Gas plc Annual Report and Accounts 2011/12Risk factor Details of the risk and examples of our responses Committee of National Grid. Inflation: Actions to minimise the impact of inflation include: transformation initiatives designed to improve productivity or reduce the cost of delivering outputs; contracting for future needs where appropriate; and a multi-supplier tendering process to ensure costs are minimised. Pensions: We negotiate recovery of pension costs from our regulators.Financing and liquidity Maintenance and growth of our business requires access to capital markets at commercially acceptable interest rates. Our business is financed through cash generated from our ongoing operations, bank lending facilities and the capital markets, particularly the long-term debt capital markets. Some of the debt we issue is rated by credit rating agencies and changes to these ratings may affect both our borrowing capacity and borrowing costs. In addition, restrictions imposed by regulators may also limit how we service the financial requirements of our businesses. Financial markets can be subject to periods of volatility and shortages of liquidity, which may be exacerbated by the eurozone crisis. If we were unable to access the capital markets or other sources of finance at competitive rates for a prolonged period, our cost of financing may increase, the discretionary and uncommitted elements of our proposed capital investment programme may need to be reconsidered and the manner in which we implement our strategy may need to be reassessed. The occurrence of any such events could have a material adverse impact on our business, results and prospects. Our regulatory agreements impose lower limits for the long-term senior unsecured debt credit ratings that we must hold. In addition, our regulatory arrangements impose restrictions on the way we can operate. These include regulatory requirements for us to maintain adequate financial resources within the Company. The inability to meet such requirements may have an adverse impact on our business and financial condition. Our responses We identify short-term liquidity and long-term funding requirements by regularly producing short- and long- term cash flow forecasts, along with undertaking financial headroom analysis. To facilitate short- and long-term debt issuance, we maintain commercial paper and medium-term note programmes. We manage refinancing risk by limiting the amount of debt maturities on borrowings in any one financial year. Details of our long-term borrowings maturity profile is on page 27. We also have both committed and uncommitted bank borrowing facilities that are available for general corporate purposes to support our liquidity requirements. The majority of our committed borrowing facilities are used to provide back up to our commercial paper programmes or other specific debt issuances. To date, these have never been drawn and there is no current intention to draw them in the future. We consider restrictions imposed by regulatory agreements in preparing cash flow forecasts and determining our future funding requirements. Details of the programmes and facilities we maintain can be found in the debt investors section of National Grid’s website.Customers and Customers and counterparties may not perform their obligations. We have significant concentrations ofcounterparties receivables with a small number of large gas utilities. Our responses Advance payments, security deposits or other forms of collateral may be obtained, to reduce the risk from customer default. The Finance Committee of National Grid has agreed a policy for managing counterparty risk that sets limits to the exposure we can have based on an individual counterparty’s credit rating from independent rating agencies. Limits are monitored daily and amended as credit ratings change and are set on a portfolio basis to ensure that our total exposure is acceptable. Given the economic uncertainties in the eurozone, we consider other leading indicators of counterparty distress and reduce exposure below the approved limits, if

Where multiple financial transactions are entered into with a single counterparty, a netting arrangement is usually put in place to reduce our exposure to the credit risk arising. More information about managing counterparty risk is given in note 27(c) to the consolidated financial statements.Employees and others We need to attract and retain employees with the skills and experience required to deliver our strategy. We also need to ensure they and others acting on our behalf, are engaged to act in our best interests. Our responses To demonstrate our commitment to this important area, one of our 2012/13 priorities is to increase levels of employee engagement across all of our teams. We will use our engaging for performance framework, see page 7, to deliver this priority. We are confident that we understand our resource and skills gaps in our gas transmission business and plans are in place to respond to these risks. Plans are not just aimed at recruiting qualified engineers with experience in our industry, but recognise that we must look more widely, identifying capable individuals we can train and develop to create a talent pipeline that will support our growth over time. In our Gas Distribution business, plans are being developed to ensure this is also the case. We also continue to work closely with existing partners, and when appropriate, will seek to create new partnerships. Through our partnerships we can leverage external resources, expertise and best practices to supplement our internal knowledge and experience and ensure that we can deliver our planned capital investment programme. We maintain a strong commitment to ethical business conduct. National Grid’s ethics and compliance office was established specifically to answer questions and address concerns about unethical behaviour affecting National Grid’s businesses.Information assuranceThe Board of National Grid considers that it is imperative tohave accurate and reliable information to enable informed andtimely decisions to be taken that further our objectives. Keyelements in managing information assurance risks includeeducation, training and awareness.These initiatives emphasise the importance of informationsecurity, the quality of data collection and the affirmationprocess that supports our business transactions, evidencing ourdecisions and actions. All communication channels, includingtraining for doing the right thing, make it clear that the accurateand honest reporting of data and other information must neverbe compromised. These initiatives are supported by the letter ofassurance process in which managers affirm, among otherthings, they have control frameworks in place to ensure dataand other information is reported accurately. In line withongoing transformation initiatives, we continue to monitor andevolve our control processes.

The Company is evaluating the impact of thesestandards on its financial statements. The standards arerequired to be adopted by the Company on 1 April 2013,subject to endorsement by the EU.The amended version of IAS 19 on employee benefits, issuedin June 2011 and effective for periods beginning after 1January 2013 (subject to EU endorsement), requires netinterest to be calculated on the net defined benefitliability/(asset) using the same discount rate used to measurethe defined benefit obligation. Where the expected return onassets exceeds the discount rate, the adoption of theamended standard will result in a reduction in reported netincome with a corresponding increase in other comprehensiveincome. As the Company does not recognise any definedbenefit pension obligations within its financial statements, thisamended standard will not directly impact on the Company’sfinancial statements.Other standards and interpretations or amendments theretowhich have been issued, but are not yet effective, are notexpected to have a material impact on the Company’sconsolidated financial statements.

Segmental analysisThe Board of Directors is National Grid Gas plcs chief operating decision making body (as defined by IFRS 8 on operating segments). Thesegmental analysis is based on the information the Board of Directors uses internally for the purposes of evaluating the performance ofoperating segments and determining resource allocation between segments. The performance of operating segments is assessed principallyon the basis of operating profit before exceptional items. The following table describes the main activities for each operating segment:Gas Transmission - the gas transmission network in the UK and the associated UK liquefied natural gas (LNG) storage activitiesGas Distribution - four of the eight regional networks of Great Britains gas distribution systemGas Metering - regulated gas metering activities in the UKOther activities relate to the xoserve business which provides transportation transaction services on behalf of all the major gas networktransportation companies, including ourselves, together with corporate activities.Our segments are unchanged from those reported in the financial statements for the year ended 31 March 2011.

  • 55. National Grid Gas plc Annual Report and Accounts 2011/12 536. Taxation continuedFactors that may affect future tax chargesA reduction in the UK corporation tax rate to 24% from April 2012 was announced in the 2012 UK Budget Report. This has been substantivelyenacted and deferred tax balances have been calculated at this rate.Other changes, such as the proposed reduction in the UK corporation tax rate to 23% from April 2013, with a further 1% reduction in thefollowing year, will result in a UK corporation tax rate of 22% from April 2014. These changes have not been substantively enacted as at thebalance sheet date and have not been reflected in these financial statements.The process for reforming the UKs rules for taxing controlled foreign companies completed with the issue of draft legislation in the FinanceBill 2012. We do not expect any material adverse impact of this legislation on our holdings in foreign operations.7.

Cash flows are expected to be incurred between 2012 and2060.A number of uncertainties affect the calculation of the provision including the impact of regulation, the accuracy of the site surveys,unexpected contaminants, transportation costs, the impact of alternative technologies and changes in the discount rate. The provisionincorporates our best estimate of the financial effect of these uncertainties, but future material changes in any of the assumptions couldmaterially impact on the calculation of the provision and hence the income statement.The undiscounted amount of the provision at 31 March 2012 was £92m (2011: £112m), being the best undiscounted estimate of the liabilityhaving regard to these uncertainties.Restructuring provisionAt 31 March 2012, £14m of the total restructuring provision (2011: £26m) related to the restructuring of our LNG storage facilities, and £13mconsisted of provisions for the disposal of surplus leasehold interests and rates payable on surplus properties (2011: £14m). The expectedpayment dates for property restructuring costs remain uncertain. The remainder of the restructuring provision related to businessreorganisation costs, to be paid over the next two years.Other provisionsOther provisions at 31 March 2012 include £24m (2011: £22m) in respect of employer liability claims. In accordance with insurance industrypractice, the estimates for employer liability claims are based on experience from previous years and, therefore, there is no identifiablepayment date associated with these items.

Actuarial information on pensionsThe National Grid UK Pension Scheme is funded with assets held in a separate trustee administered fund. The defined benefit section of thescheme is subject to independent actuarial valuation at least every three years, on the basis of which the qualified actuary certifies the rate ofemployers contribution which, together with the specified contributions payable by employees and the proceeds from the schemes assets,are expected to be sufficient to fund the benefits payable under the scheme. The next valuation will be based on the position at 31 March2013. The results of the 2010 valuation are shown below:Latest full actuarial valuation 31 March 2010Actuary Towers WatsonMarket value of scheme assets at latest valuation £13,399mActuarial value of benefits due to members £(13,998)mMarket value as percentage of benefits 96%Funding deficit £599mFunding deficit (net of tax) £455mThe 2010 actuarial valuation showed that, based on long-term financial assumptions, the contribution rate required to meet future benefitaccrual was 35% of pensionable earnings (32% employers and 3% employees). In addition, National Grid makes payments to the scheme tocover administration costs and the Pension Protection Fund levy. The employer contribution rate will be reviewed as part of the next valuationin 2013, while the administration costs are reviewed annually.Following the 2010 actuarial valuation, National Grid and the Trustees agreed a recovery plan which will see the funding deficit repaid by 31March 2027. Under the schedule of contributions, no deficit contributions were made in 2010/11 or 2011/12. An annual payment of £47m,rising in line with retail price inflation from March 2010, will commence in 2012/13 and continue until 2027.Following this agreement, the Company has established a secured bank account with a charge in favour of the Trustees of the National GridUK Pension Scheme. The balance of the bank account at 31 March 2012 was £142m. The funds in the bank account will be paid to thescheme in the event that National Grid Gas plc is subject to an insolvency event, or is given notice of less than 12 months that Ofgem intendsto revoke its licence under the Gas Act 1986.

Supplementary information on derivative financial instrumentsTreasury financial instrumentsDerivatives are financial instruments that derive their value from the price of an underlying item such as interest rates, foreign exchange,credit spreads, commodities, equities or other indices. Derivatives enable their users to alter exposure to these market or credit risks. We usederivatives to manage the interest rate and foreign exchange risks from our financing portfolio and this enables the optimisation of the overallcost of accessing debt capital markets.We calculate fair value of the financial derivatives by discounting all future cash flows by the market yield curve at the balance sheet date.The market yield curve for each currency is obtained from external sources for interest and foreign exchange rates. In the case of derivativeinstruments that include options, the Blacks variation of the Black-scholes model is used to calculate the fair value.Hedging policies using derivative financial instruments are further explained in note 27 and, where possible, derivatives held as hedginginstruments are formally designated as hedges as defined in IAS 39. Derivatives may qualify as hedges for accounting purposes if they arefair value hedges or cash flow hedges. These are described as follows:Fair value hedgesFair value hedges principally consist of interest rate and cross-currency swaps that are used to protect against changes in the fair value offixed-rate, long-term financial instruments due to movements in market interest rates. For qualifying fair value hedges, all changes in the fairvalue of the derivative and changes in the fair value of the item in relation to the risk being hedged are recognised in the income statement. Ifthe hedge relationship is terminated, the fair value adjustment to the hedged item continues to be reported as part of the basis of the item andis amortised to the income statement as a yield adjustment over the remainder of the life of the hedged item.Cash flow hedgesExposure arises from the variability in future interest and currency cash flows on assets and liabilities which bear interest at variable rates orare in a foreign currency. Interest rate and cross-currency swaps are maintained, and designated as cash flow hedges where they qualify, tomanage this exposure. Fair value changes on designated cash flow hedges are initially recognised directly in the cash flow hedge reserve, asgains or losses recognised in equity. Amounts are transferred from equity and recognised in the income statement as the income or expenseis recognised on the hedged asset or liability.Forward foreign currency contracts are used to hedge anticipated and committed future currency cash flows. Where these contracts qualifyfor hedge accounting, they are designated as cash flow hedges. On recognition of the underlying transaction in the financial statements, theassociated hedge gains and losses deferred in equity are transferred and included with the recognition of the underlying transaction.The gains and losses on ineffective portions of such derivatives are recognised immediately in remeasurements within the income statement.When a hedging instrument expires or is sold, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or lossexisting in equity at that time remains in equity and is recognised when the forecast transaction is ultimately recognised in the incomestatement or on the balance sheet. When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was reportedin equity is immediately transferred to remeasurements within the income statement.Derivatives not in a formal hedge relationshipOur policy is not to use derivatives for trading purposes. However, due to the complex nature of hedge accounting under IAS 39, somederivatives may not qualify for hedge accounting, or are specifically not designated as a hedge where natural offset is more appropriate.Changes in the fair value of any derivative instruments that do not qualify for hedge accounting are recognised immediately inremeasurements within the income statement.
  • 67. National Grid Gas plc Annual Report and Accounts 2011/12 6527. Financial riskOur activities expose us to a variety of financial risks: market risk, including foreign exchange risk; fair value interest rate risk and cash flowinterest rate risk; credit risk; and liquidity risk. Our overall risk management programme focuses on the unpredictability of financial marketsand seeks to minimise potential adverse effects on financial performance. We use financial instruments, including derivative financialinstruments to manage risks of this type.Risk management related to financial activities is carried out by a central treasury department under policies approved by the FinanceCommittees of the Board of Directors of National Grid plc and the Company. The objective of the treasury department is to manage fundingand liquidity requirements, including managing associated financial risks, to within acceptable boundaries. The Finance Committee of theBoard provides written principles for overall risk management, as well as written policies covering specific areas, such as foreign exchangerisk, interest rate risk, credit risk, use of derivative financial instruments and non-derivative financial instruments, and investment of excessliquidity.(a) Market risk(i) Foreign exchange riskWe are exposed to foreign exchange risk arising from non-sterling future commercial transactions and non-sterling recognised assets andliabilities.Our policy for managing foreign exchange risk is to hedge contractually committed foreign currency cash flows over a prescribed minimumsize. Where cash forecasts are less certain, we hedge a proportion of the foreign currency flows based on the probability of those cash flowsoccurring. Instruments used to manage foreign exchange risk include foreign exchange forward contracts and foreign exchange swaps.During 2012 and 2011, derivative financial instruments were used to manage foreign exchange risk as follows: 2012 Sterling Euro Dollar Other Total £m £m £m £m £mCash and cash equivalents - 1 - - 1Financial investments 451 - - - 451Borrowings (i) (6,135) (832) (802) (370) (8,139)Pre-derivative position (5,684) (831) (802) (370) (7,687)Derivative effect (1,458) 787 800 370 499Net debt position (7,142) (44) (2) - (7,188) 2011 Sterling Euro Dollar Other Total £m £m £m £m £mCash and cash equivalents 82 1 - - 83Financial investments 242 - - - 242Borrowings (i) (5,962) (876) (719) (345) (7,902)Pre-derivative position (5,638) (875) (719) (345) (7,577)Derivative effect (1,406) 848 720 345 507Net debt position (7,044) (27) 1 - (7,070)(i) Includes bank overdraftsThere was no significant currency exposure on other financial instruments, including trade receivables and payables, and other receivablesand payables.

Financial risk continued(a) Market risk continued(ii) Cash flow and fair value interest rate riskInterest rate risk arises on our long-term borrowings. Borrowings issued at variable rates expose us to cash flow interest rate risk, partiallyoffset by cash held at variable rates. Borrowings issued at fixed rates expose us to fair value interest rate risk.Our interest rate risk management policy seeks to minimise total financing costs (being interest costs and changes in the market value ofdebt) subject to constraints. We do this by using fixed and floating-rate debt and derivative financial instruments, including interest rateswaps, swaptions and forward rate agreements.We hold some borrowings on issue that are inflation linked. We believe that these provide a partial economic offset to the inflation riskassociated with our inflation linked revenues.The following table sets out the carrying amount, by contractual maturity, of borrowings that are exposed to interest rate risk before taking intoaccount interest rate swaps: 2012 2011 £m £mFixed interest rate borrowingsLess than 1 year (104) (83)In 1 - 2 years (481) (24)In 2 - 3 years - (501)In 3 - 4 years - -In 4 - 5 years (54) -More than 5 years (2,781) (2,658) (3,420) (3,266)Floating interest rate borrowings (including RPI linked) (4,719) (4,583)Non-interest bearing borrowings - (53)Total borrowings (8,139) (7,902)During 2012 and 2011, net debt was managed using derivative instruments to hedge interest rate risk as follows: 2012 Fixed Floating rate rate RPI (i) Other (ii) Total £m £m £m £m £mCash and cash equivalents 1 - - - 1Financial investments - 431 - 20 451Borrowings (iii) (3,420) (950) (3,769) - (8,139)Pre-derivative position (3,419) (519) (3,769) 20 (7,687)Derivative effect 819 (435) 115 - 499Net debt position (iv) (2,600) (954) (3,654) 20 (7,188) 2011 Fixed Floating rate rate RPI(i) Other (ii) Total £m £m £m £m £mCash and cash equivalents 83 - - - 83Financial investments - 242 - - 242Borrowings (iii) (3,266) (958) (3,625) (53) (7,902)Pre-derivative position (3,183) (716) (3,625) (53) (7,577)Derivative effect 1,413 (1,135) 229 - 507Net debt position (iv) (1,770) (1,851) (3,396) (53) (7,070)(i) The post-derivative impact represents financial instruments linked to UK RPI.(ii) Represents financial instruments which are not directly affected by interest rate risk, including investments in equity or other non-interest bearing instruments.(iii) Includes bank overdrafts(iv) The post derivative impact includes short-dated derivative contracts maturing within 12 months of the balance sheet date.

Financial risk continued(c) Credit riskWe are exposed to the risk of loss resulting from counterparties default on their commitments including failure to pay or make a delivery on acontract. This risk is inherent in commercial business activities. Credit risk arises from cash and cash equivalents, derivative financialinstruments, and deposits with banks and financial institutions, as well as credit exposures to wholesale and retail customers, includingoutstanding receivables and committed transactions.Treasury related credit riskCounterparty risk arises from the investment of surplus funds and from the use of derivative instruments. Our limits are managed by thecentral treasury department of National Grid, as explained under Principal risk factors on pages 16 and 17.As at 31 March 2012 and 2011, we had a number of exposures to individual counterparties. In accordance with our treasury policies andcounterparty credit exposure utilisations are monitored daily against the counterparty credit limits. Counterparty credit ratings and marketconditions are reviewed continually with limits being revised and utilisation adjusted, if appropriate. We do not expect any significant lossesfrom non-performance by these counterparties.The counterparty exposure under derivative financial contracts as shown in note 11 was £942m (2011: £615m); after netting agreements itwas £789m (2011: £576m). This exposure is further reduced by collateral received as shown in note 16.Wholesale and retail credit riskOur principal commercial exposure is governed by the credit rules within the Uniform Network Code. These lay down the level of credit relativeto the regulatory asset value for each credit rating. Sales to retail customers, such as those requiring connections, are usually settled in cashor using major credit cards. Management does not expect any significant losses of receivables that have not been provided for as shown innote 13.(d) Liquidity analysisWe determine our liquidity requirements by the use of both short and long-term cash flow forecasts. These forecasts are supplemented by afinancial headroom analysis which is used to assess funding adequacy for at least a 12 month period.The following is an analysis of the contractual undiscounted cash flows payable under financial liabilities, and derivative assets and liabilitiesas at the balance sheet date: Due Due Due Due between between 3 years within 1 and 2 2 and 3 and 1 year years years beyond TotalAt 31 March 2012 £m £m £m £m £mNon-derivative financial liabilitiesBorrowings (847) (475) (125) (6,661) (8,108)Interest payments on borrowings (i) (229) (211) (211) (3,233) (3,884)Other non-interest bearing liabilities (380) (16) - - (396)Derivative financial liabilitiesDerivative contracts - receipts 122 475 451 218 1,266Derivative contract - payments (75) (379) (187) (121) (762)Total at 31 March 2012 (1,409) (606) (72) (9,797) (11,884) Due Due Due Due between between 3 years within 1 and 2 2 and 3 and 1 year years years beyond TotalAt 31 March 2011 £m £m £m £m £mNon-derivative financial liabilitiesBorrowings (679) (223) (501) (6,645) (8,048)Interest payments on borrowings (i) (237) (237) (219) (3,494) (4,187)Other non-interest bearing liabilities (455) (22) - - (477)Derivative financial liabilitiesDerivative contract - receipts 95 119 132 726 1,072Derivative contract - payments (23) (32) (23) (549) (627)Total at 31 March 2011 (1,299) (395) (611) (9,962) (12,267)(i) The interest on borrowings is calculated based on borrowings held at 31 March without taking account of future issues.

  • 71. National Grid Gas plc Annual Report and Accounts 2011/12 6927. Financial risk continued(e) Sensitivity analysisFinancial instruments affected by market risk include borrowings, deposits and derivative financial instruments. The following analysisillustrates the sensitivity to changes in market variables, being UK interest rates and the UK RPI.The analysis excludes the impact of movements in market variables on the carrying value of provisions.The sensitivity analysis has been prepared on the basis that the amount of net debt, the ratio of fixed to floating interest rates of the debt andderivatives portfolio, and the proportion of financial instruments in foreign currencies are all constant, and on the basis of the hedgedesignations in place at 31 March 2012 and 31 March 2011, respectively. As a consequence, this sensitivity analysis relates to the positionsat those dates and is not representative of the years then ended, as all of these varied.The following assumptions were made in calculating the sensitivity analysis:• the balance sheet sensitivity to interest rates relates only to derivative financial instruments and available-for-sale investments, as debt and other deposits are carried at amortised cost and so their carrying value does not change as interest rates move;• the sensitivity of accrued interest to movements in interest rates is calculated on net floating rate exposures on debt, deposits and derivative instruments;• changes in the carrying value of derivatives from movements in interest rates designated as cash flow hedges are assumed to be recorded fully within equity;• changes in the carrying value of derivative financial instruments not in hedging relationships only affect the income statement;• all other changes in the carrying value of derivative financial instruments designated as hedges are fully effective with no impact on the income statement;• debt with a maturity below one year is floating rate for the accrued interest part of the calculation;• the floating leg of any swap or any floating rate debt is treated as not having any interest rate already set, therefore a change in interest rates affects a full 12 month period for the accrued interest portion of the sensitivity calculations; and• sensitivity to the UK RPI does not take into account any changes to revenue or operating costs that are affected by the UK RPI or inflation generally. Inflation linked derivative sensitivity assumes that changes to nominal interest rates are solely due to changes in inflation.Using the above assumptions, the following table shows the illustrative impact on the income statement and items that are recognised directlyin equity that would result from reasonably possible movements in changes in the UK RPI and UK interest rates, after the effects of tax. 2012 2011 Other Other Income Equity Income Equity statement Reserves statement Reserves -/+ £m -/+ £m -/+ £m -/+ £mUK RPI +/- 0.50% * 13 - 12 -UK interest rates +/- 0.50% 6 14 7 13* Excludes sensitivities to limited price Inflation index, further details on sensitivities are provided in note 27(b).The income statement sensitivities impact interest expense and financial instrument remeasurements.(f) Capital and risk managementOur objectives when managing capital are to safeguard the Companys ability to continue as a going concern, to remain within regulatoryconstraints and to maintain an efficient mix of debt and equity funding thus achieving an optimal capital structure and cost of capital.The principal measure of balance sheet efficiency is gearing calculated as net debt expressed as a percentage of regulatory asset value(RAV). The RAV gearing ratio at 31 March 2012 was 52% compared with 54% at 31 March 2011. We regularly review and maintain or adjustthe capital structure as appropriate in order to manage the level of RAV gearing.Our licence and some of our bank loan agreements impose lower limits for the long-term credit ratings that the Company must hold. Theserequirements are monitored on a regular basis in order to ensure compliance.

Cash flows are expected to be incurred between 2012 and2060.A number of uncertainties affect the calculation of the provision including the impact of regulation, the accuracy of the site surveys,unexpected contaminants, transportation costs, the impact of alternative technologies and changes in the discount rate. The provisionincorporates our best estimate of the financial effect of these uncertainties, but future material changes in any of the assumptions couldmaterially impact on the calculation of the provision and hence the income statement.The undiscounted amount of the provision at 31 March 2012 was £92m (2011: £112m), being the best undiscounted estimate of the liabilityhaving regard to these uncertainties.Restructuring provisionAt 31 March 2012, £14m of the total restructuring provision (2011: £26m) related to the restructuring of our LNG storage facilities, and £13mconsisted of provisions for the disposal of surplus leasehold interests and rates payable on surplus properties (2011: £14m).
