Accounting policies

General information

This document constitutes the Annual Report and Financial Statements in accordance with UK Listing Rules requirements and the Annual Report on Form 20-F in accordance with the US Securities Exchange Act of 1934.

The Consolidated Financial Statements of InterContinental Hotels Group PLC (the Group or IHG) for the year ended 31 December 2017 were authorised for issue in accordance with a resolution of the Directors on 19 February 2018. InterContinental Hotels Group PLC (the Company) is incorporated and domiciled in Great Britain and registered in England and Wales.

Significant accounting policies

Basis of preparation

The Consolidated Financial Statements of IHG have been prepared on a going concern basis and under the historical cost convention, except for available-for-sale equity securities and derivatives which are measured at fair value. The Consolidated Financial Statements have been prepared in accordance with International Financial Reporting Standards (IFRSs) as issued by the IASB and in accordance with IFRS as adopted by the European Union (EU) and as applied in accordance with the provisions of the Companies Act 2006. IFRS as adopted by the EU differs in certain respects from IFRS as issued by the IASB. However, the differences have no impact on the Consolidated Financial Statements for the years presented.

With effect from 1 January 2017, the Group has adopted:

• ‘Amendments to IAS 7 Statement of Cash Flows: Disclosure Initiative’, which requires disclosure of changes in liabilities arising from financing activities, including both changes arising from cash flows and non-cash changes, such as foreign exchange adjustments. This new disclosure is provided in note 20 to the Group Financial Statements.

• ‘Amendments to IAS 12 Income Taxes: Recognition of Deferred Tax Assets for Unrealised Losses’. Application of these amendments has had no impact on the Group Financial Statements.

• Amendments to existing standards arising from the Annual Improvements to IFRSs 2014-2016 cycle. These amendments have not impacted the Group Financial Statements.

Presentational currency

The Consolidated Financial Statements are presented in millions of US dollars reflecting the profile of the Group’s revenue and operating profit which are primarily generated in US dollars or US dollar-linked currencies.

In the Consolidated Financial Statements, equity share capital, the capital redemption reserve and shares held by employee share trusts are translated into US dollars at the rates of exchange on the last day of the period; the resultant exchange differences are recorded in other reserves.

The functional currency of the Parent Company is sterling since this is a non-trading holding company located in the United Kingdom that has sterling denominated share capital and whose primary activity is the payment and receipt of sterling dividends and of interest on sterling denominated external borrowings and inter-company balances.

Basis of consolidation

The Consolidated Financial Statements comprise the Financial Statements of the Parent Company and entities controlled by the Group. Control exists when the Group has:

• Power over an investee (i.e. existing rights that give it the current ability to direct the relevant activities of the investee);

• Exposure, or rights, to variable returns from its involvement with the investee; and

• The ability to use its power over the investee to affect its returns.

All intra-group balances and transactions are eliminated on consolidation.

The assets, liabilities and results of those businesses acquired or disposed of are consolidated for the period during which they were under the Group’s control.

The Group operates a deferred compensation plan in the US which allows certain employees to make additional provision for retirement, through the deferral of salary with matching company contributions. Employees can draw down on the plan in certain limited circumstances during employment. The assets of the plan are held in a company-owned trust which is not consolidated as the relevant activity of the trust, being the investment of the funds in the trust, is directed by the participating employees of the plan and the company has no exposure to the gains and losses resulting from those investment decisions. The assets of the trust are held solely for the benefit of the participating employees and to pay plan expenses, other than in the case of a company insolvency in which case they can be claimed by the general creditors of the company. At 31 December 2017, the trust had assets with a fair value of $197m (2016: $161m).

Foreign currencies

Transactions in foreign currencies are translated to functional currency at the exchange rates ruling on the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are retranslated to the functional currency at the relevant rates of exchange ruling on the last day of the period. Foreign exchange differences arising on translation are recognised in the income statement except on foreign currency borrowings that provide a hedge against a net investment in a foreign operation. These are taken directly to the currency translation reserve until the disposal of the net investment, at which time they are recycled against the gain or loss on disposal.

The assets and liabilities of foreign operations, including goodwill, are translated into US dollars at the relevant rates of exchange ruling on the last day of the period. The revenues and expenses of foreign operations are translated into US dollars at average rates of exchange for the period. The exchange differences arising on retranslation are taken directly to the currency translation reserve. On disposal of a foreign operation, the cumulative amount recognised in the currency translation reserve relating to that particular foreign operation is recycled against the gain or loss on disposal.

Property, plant and equipment

Property, plant and equipment are stated at cost less depreciation and any impairment.

Repairs and maintenance costs are expensed as incurred.

Land is not depreciated. All other property, plant and equipment are depreciated to a residual value over their estimated useful lives, namely:

• Buildings – lesser of 50 years and unexpired term of lease; and

• Fixtures, fittings and equipment – three to 25 years.

All depreciation is charged on a straight-line basis. Residual value is re-assessed annually.

Property, plant and equipment are tested for impairment when events or changes in circumstances indicate that the carrying value may not be recoverable. Assets that do not generate independent cash flows are combined into cash-generating units. If carrying values exceed their estimated recoverable amount, the assets or cash-generating units are written down to the recoverable amount. Recoverable amount is the greater of fair value less costs of disposal and value in use. Value in use is assessed based on estimated future cash flows discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. Impairment losses, and any subsequent reversals, are recognised in the income statement.

On adoption of IFRS, the Group retained previous revaluations of property, plant and equipment which are included at deemed cost as permitted by IFRS 1 ‘First-time Adoption of International Financial Reporting Standards’.

Business combinations and goodwill

On the acquisition of a business, identifiable assets and liabilities acquired are measured at their fair value. Contingent liabilities assumed are measured at fair value unless this cannot be measured reliably, in which case they are not recognised but are disclosed in the same manner as other contingent liabilities. The measurement of deferred tax assets and liabilities arising on acquisition is as described in the general principles detailed within the ‘Taxes’ accounting policy note on page 98 with the exception that no deferred tax is provided on taxable temporary differences in connection with the initial recognition of goodwill.

Goodwill is recorded at cost, being the difference between the fair value of the consideration and the fair value of net assets acquired. Following initial recognition, goodwill is measured at cost less any accumulated impairment losses and is not amortised.

Goodwill is tested for impairment at least annually by comparing carrying values of cash-generating units with their recoverable amounts. Impairment losses relating to goodwill cannot be subsequently reversed.

Transaction costs are expensed and are not included in the cost of acquisition.

Intangible assets

Brands

Externally acquired brands are initially recorded at cost if separately acquired or fair value if acquired as part of a business combination, provided the brands are controlled through contractual or other legal rights, or are separable from the rest of the business, and the fair value can be reliably measured. Brands are amortised over their estimated useful lives (and tested for impairment if there are indicators of impairment) or tested for impairment at least annually if determined to have indefinite lives.

The costs of developing internally generated brands are expensed as incurred.

Management contracts

Management contracts acquired as part of a business combination are initially recorded at the fair value attributed to those contracts on acquisition.

When hotel assets are sold and a purchaser enters into a franchise or management contract with the Group, the Group capitalises as part of the gain or loss on disposal an estimate of the fair value of the contract entered into.

The value of management contracts is amortised on a straight-line basis over the life of the contract including any extension periods at IHG’s option up to a maximum of 50 years.

Software

Acquired and internally developed software are capitalised on the basis of the costs incurred to acquire and bring to use the specific software. Costs are generally amortised over estimated useful lives of three to five years on a straight-line basis.

Internally generated development costs are expensed unless forecast revenues exceed attributable forecast development costs, in which case they are capitalised and amortised over the estimated useful life of the asset.

Other intangible assets

Amounts paid to hotel owners to secure management contracts and franchise agreements are capitalised and amortised on a straight-line basis over their estimated useful lives, being the full contractual term, up to a maximum of 50 years.

Intangible assets are reviewed for impairment when events or changes in circumstances indicate that the carrying value may not be recoverable.

Associates and joint ventures

An associate is an entity over which the Group has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the entity, but is not control or joint control over those policies.

A joint venture exists when two or more parties have joint control over, and rights to the net assets of, the venture. Joint control is the contractually agreed sharing of control which only exists when decisions about the relevant activities require the unanimous consent of the parties sharing control.

Associates and joint ventures are accounted for using the equity method unless the associate or joint venture is classified as held for sale. Under the equity method, the Group’s investment is recorded at cost adjusted by the Group’s share of post-acquisition profits and losses and other movements in the investee’s reserves. When the Group’s share of losses exceeds its interest in an associate or joint venture, the Group’s carrying amount is reduced to $nil and recognition of further losses is discontinued except to the extent that the Group has incurred legal or constructive obligations or made payments on behalf of an associate or joint venture.

If there is objective evidence that an associate or joint venture is impaired, an impairment charge is recognised if the carrying amount of the investment exceeds its recoverable amount.

Upon loss of significant influence over an associate or joint control of a joint venture, any retained investment is measured at fair value with any difference to carrying value recognised in the income statement.

Financial assets

The Group classifies its financial assets into one of the two following categories: loans and receivables or available-for-sale financial assets. Management determines the classification of financial assets on initial recognition and they are subsequently held at amortised cost (loans and receivables) or fair value (available-for-sale financial assets). Interest on loans and receivables is calculated using the effective interest rate method and is recognised in the income statement as interest income. Changes in fair values of available-for-sale financial assets are recorded directly in equity within the unrealised gains and losses reserve. On disposal, the accumulated fair value adjustments recognised in equity are recycled to the income statement. Dividends from available-for-sale financial assets are recognised in the income statement as other operating income and expenses.

Financial assets are assessed for impairment at each period-end date. In the case of an equity investment classified as available-for-sale, a significant or prolonged decline in fair value below cost is evidence that the asset is impaired. If an available-for-sale financial asset is impaired, the difference between original cost and fair value is transferred from equity to the income statement to the extent of any cumulative loss recorded in equity, with any excess charged directly to the income statement. Subsequent impairment reversals relating to previously impaired equity instruments are recorded in equity.

Trade receivables

Trade receivables are recorded at their original amount less provision for impairment. It is the Group’s policy to provide for 100% of the previous month’s aged receivables balances which are more than 180 days past due. Adjustments to the policy may be made due to specific or exceptional circumstances. The carrying amount of the receivable is reduced through the use of a provision account and movements in the provision are recognised in the income statement within cost of sales. When a previously provided trade receivable is uncollectable, it is written off against the provision.

Cash and cash equivalents

Cash comprises cash in hand and demand deposits.

Cash equivalents are short-term highly liquid investments with an original maturity of three months or less that are readily convertible to known amounts of cash and subject to insignificant risk of changes in value.

In the statement of cash flows, cash and cash equivalents are shown net of short-term overdrafts which are repayable on demand and form an integral part of the Group’s cash management.

Assets held for sale

Assets and liabilities are classified as held for sale when their carrying amount will be recovered principally through a sale transaction rather than continuing use and a sale is highly probable and expected to complete within one year. For a sale to be highly probable, management need to be committed to a plan to sell the asset and the asset must be actively marketed for sale at a price that is reasonable in relation to its current fair value.

Assets designated as held for sale are held at the lower of carrying amount at designation and fair value less costs to sell.

Depreciation is not charged against property, plant and equipment classified as held for sale.

Offsetting of financial assets and financial liabilities

Financial assets and financial liabilities are offset and the net amount is reported in the Group statement of financial position if there is a currently enforceable legal right to offset the recognised amounts and there is an intention to settle on a net basis or to realise the assets and settle the liabilities simultaneously. To meet these criteria, the right of set-off must not be contingent on a future event and must be legally enforceable in all of the following circumstances: the normal course of business, the event of default and the event of insolvency or bankruptcy of the Group and all of the counterparties.

Bank and other borrowings

Bank and other borrowings are initially recognised at the fair value of the consideration received less directly attributable transaction costs. They are subsequently measured at amortised cost. Finance charges, including the transaction costs and any discount or premium on issue, are recognised in the income statement using the effective interest rate method.

Borrowings are classified as non-current when the repayment date is more than 12 months from the period-end date or where they are drawn on a facility with more than 12 months to expiry.

Derivative financial instruments and hedging

Derivatives are initially recognised and subsequently re-measured at fair value. The method of recognising the re-measurement depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged.

Changes in the fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income and the unrealised gains and losses reserve to the extent that the hedges are effective. When the hedged item is recognised, the cumulative gains and losses on the related hedging instrument are reclassified to the income statement.

Changes in the fair value of derivatives designated as net investment hedges are recorded in other comprehensive income and the currency translation reserve to the extent that the hedges are effective. The cumulative gains and losses remain in equity until a foreign operation is sold, at which point they are reclassified to the income statement.

Changes in the fair value of derivatives which have either not been designated as hedging instruments or relate to the ineffective portion of hedges are recognised immediately in the income statement.

Documentation outlining the measurement and effectiveness of any hedging arrangement is maintained throughout the life of the hedge relationship.

Interest arising from currency derivatives and interest rate swaps is recorded in either financial income or expenses over the term of the agreement, unless the accounting treatment for the hedging relationship requires the interest to be taken to reserves.

Self insurance

Liabilities in respect of self insured risks include projected settlements for known and incurred but not reported claims. Projected settlements are estimated based on historical trends and actuarial data.

Provisions

Provisions are recognised when the Group has a present obligation as a result of a past event, it is probable that a payment will be made and a reliable estimate of the amount payable can be made. If the effect of the time value of money is material, the provision is discounted using a currentpre-tax discount rate that reflects the risks specific to the liability.

An onerous contract provision is recognised when the unavoidable costs of meeting the obligations under a contract exceed the economic benefits expected to be received under it.

In respect of litigation, provision is made when management consider it probable that payment may occur even though the defence of the related claim may still be ongoing through the court process.

Taxes

Current tax

Current income tax assets and liabilities for the current and prior periods are measured at the amount expected to be recovered from, or paid to, the tax authorities, including interest. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted at the end of the reporting period.

Deferred tax

Deferred tax assets and liabilities are recognised in respect of temporary differences between the tax base and carrying value of assets and liabilities including accelerated capital allowances, unrelieved tax losses, unremitted profits from subsidiaries, gains rolled over into replacement assets, gains on previously revalued properties and other short-term temporary differences.

Judgement is used when assessing the extent to which deferred tax assets, particularly in respect of tax losses, should be recognised. Deferred tax assets are therefore recognised to the extent that it is regarded as probable that there will be sufficient and suitable taxable profits (including the future release of deferred tax liabilities) in the relevant legal entity or tax group against which such assets can be utilised in the future. For this purpose, forecasts of future taxable profits are considered by assessing the Group’s forecast revenue and profit models, taking into account future growth predictions and operating cost assumptions. Accordingly, changes in assumptions to the Group’s forecasts may have an impact on the amount of future taxable profits and therefore the period over which any deferred tax assets might be recovered.

Deferred tax is calculated at the tax rates that are expected to apply in the periods in which the asset or liability will be settled, based on rates enacted or substantively enacted at the end of the reporting period.

Where deferred tax assets and liabilities arise in the same entity or group of entities and there would be a legal right to offset the assets and liabilities were they to reverse, the assets and liabilities are also offset on the Group statement of financial position. Similarly, if there is no legal right to offset assets against liabilities, the assets and liabilities are not offset.

Retirement benefits

Defined contribution plans

Payments to defined contribution schemes are charged to the income statement as they fall due.

Defined benefit plans

Plan assets are measured at fair value and plan liabilities are measured on an actuarial basis, using the projected unit credit method and discounting at an interest rate equivalent to the current rate of return on a high-quality corporate bond of equivalent currency and term to the plan liabilities. The difference between the value of plan assets and liabilities at the period-end date is the amount of surplus or deficit recorded in the statement of financial position as an asset or liability. An asset is recognised when the employer has an unconditional right to use the surplus at some point during the life of the plan or on its wind-up.

The service cost of providing pension benefits to employees, together with the net interest expense or income for the year, is charged to the income statement within ‘administrative expenses’. Net interest is calculated by applying the discount rate to the net defined benefit asset or liability, after any asset restriction. Past service costs and gains, which are the change in the present value of the defined benefit obligation for employee service in prior periods resulting from plan amendments, are recognised immediately the plan amendment occurs. Settlement gains and losses, being the difference between the settlement cost and the present value of the defined benefit obligations being settled, are recognised when the settlement occurs.

Re-measurements comprise actuarial gains and losses, the return on plan assets (excluding amounts included in net interest) and changes in the amount of any asset restrictions. Actuarial gains and losses may result from: differences between the actuarial assumptions underlying the plan liabilities and actual experience during the year or changes in the actuarial assumptions used in the valuation of the plan liabilities. Re-measurement gains and losses, and taxation thereon, are recognised in other comprehensive income and are not reclassified to profit or loss in subsequent periods.

Actuarial valuations are carried out on a regular basis and are updated for material transactions and other material changes in circumstances (including changes in market prices and interest rates) up to the end of the reporting period.

Revenue recognition

Revenue arises from the sale of goods and provision of services where these activities give rise to economic benefits received and receivable by the Group on its own account and result in increases in equity.

Revenue is derived from the following sources: franchise fees; management fees; owned and leased properties and other revenues which are ancillary to the Group’s operations, including technology fee income.

Revenue is recorded (excluding VAT and similar taxes) net of discounts.

The following is a description of the composition of revenues of the Group.

Franchise fees

Received in connection with the licence of the Group’s brand names, usually under long-term contracts with the hotel owner. The Group charges franchise royalty fees as a percentage of hotel rooms revenue and recognises the fees as the hotel revenues occur.

Management fees

Earned from hotels managed by the Group, usually under long-term contracts with the hotel owner. Management fees include a base fee, generally a percentage of hotel revenue, which is recognised as the hotel revenues occur and an incentive fee, generally based on the hotel’s annual profitability or cash flows, which is recognised over time when it is considered probable that the related performance criteria will be met.

Owned and leased

Primarily derived from hotel operations, including the rental of rooms and food and beverage sales from owned and leased hotels operated under the Group’s brand names. Revenue is recognised when rooms are occupied and food and beverages are sold.

Franchise fees and management fees include liquidated damages received from the early termination of contracts.

Other revenues are recognised when earned in accordance with the terms of the contract.

Share-based payments

The cost of equity-settled transactions with employees is measured by reference to fair value at the date at which the right to the shares is granted. Fair value is determined by an external valuer using option pricing models.

The cost of equity-settled transactions is recognised, together with a corresponding increase in equity, over the period in which any performance or service conditions are fulfilled, ending on the date on which the relevant employees become fully entitled to the award (vesting date).

The income statement charge for a period represents the movement in cumulative expense recognised at the beginning and end of that period. No expense is recognised for awards that do not ultimately vest, except for awards where vesting is conditional upon a market or non-vestingcondition, which are treated as vesting irrespective of whether or not the market or non-vesting condition is satisfied, provided that all other performance and/or service conditions are satisfied.

Leases

Operating lease rentals are charged to the income statement on a straight-line basis over the term of the lease.

Assets held under finance leases, which transfer to the Group substantially all the risks and benefits incidental to ownership of the leased item, are capitalised at the inception of the lease, with a corresponding liability being recognised for the fair value of the leased asset or, if lower, the present value of the minimum lease payments. Lease payments are apportioned between the reduction of the lease liability and finance charges in the income statement so as to achieve a constant rate of interest on the remaining balance of the liability. Assets held under finance leases are depreciated over the shorter of the estimated useful life of the asset and the lease term.

Disposal of non-current assets

The Group recognises sales proceeds and any related gain or loss on disposal on completion of the sales process. In determining whether the gain or loss should be recorded, the Group considers whether it:

• Has a continuing managerial involvement to the degree associated with asset ownership;

• Has transferred the significant risks and rewards associated with asset ownership; and

• Can reliably measure and will actually receive the proceeds.

Fair value measurement

The Group measures available-for-sale equity securities and derivatives at fair value on a recurring basis and other assets when impaired by reference to fair value less costs of disposal. Additionally, the fair value of other financial assets and liabilities require disclosure.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is measured by reference to the principal market for the asset or liability assuming that market participants act in their economic best interests.

The fair value of a non-financial asset assumes the asset is used in its highest and best use, either through continuing ownership or by selling it.

The Group uses valuation techniques that maximise the use of relevant observable inputs using the following valuation hierarchy:

Level 1:	quoted (unadjusted) prices in active markets for identical assets or liabilities.
Level 2:	other techniques for which all inputs which have a significant effect on the recorded fair value are observable, either directly or indirectly.
Level 3:	techniques which use inputs which have a significant effect on the recorded fair value that are not based on observable market data.

Further disclosures on the particular valuation techniques used by the Group are provided in note 23.

For impairment testing purposes and where significant assets (such as property) are valued by reference to fair value less costs of disposal, an external valuation will normally be obtained using professional valuers who have appropriate market knowledge, reputation and independence.

Exceptional items

The Group discloses certain financial information both including and excluding exceptional items. The presentation of information excluding exceptional items allows a better understanding of the underlying trading performance of the Group and provides consistency with the Group’s internal management reporting. Exceptional items are identified by virtue of either their size or nature so as to facilitate comparison with prior periods and to assess underlying trends in the financial performance of the Group and its regional operating segments. Exceptional items can include, but are not restricted to, gains and losses on the disposal of assets, impairment charges and reversals and restructuring costs.

Critical accounting policies and the use of judgements, estimates and assumptions

In determining and applying the Group’s accounting policies, management are required to make judgements, estimates and assumptions. An accounting policy is considered to be critical if its selection or application could materially affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the Financial Statements, and the reported amounts of revenues and expenses during the reporting period. Management consider accounting for the System Fund to be a critical judgement and that critical estimates and assumptions are used in impairment testing and for measuring the loyalty programme liability, as discussed in further detail below. Estimates and assumptions are evaluated by management using historical experience and other factors believed to be reasonable based on current circumstances. Actual results could differ under different policies, judgements, estimates and assumptions or due to unforeseen circumstances.

System Fund – in addition to management or franchise fees, hotels within the IHG System (other than for Kimpton and InterContinental hotels) pay cash assessments and contributions which are collected by IHG for specific use within the System Fund (the Fund). The Fund also receives proceeds from the sale of IHG Rewards Club points. IHG exerts significant influence over the operation of the Fund, however the Fund is managed for the benefit of hotels in the System with the objective of driving revenues for the hotels. The Fund is used to pay for marketing, the IHG Rewards Club loyalty programme and the Guest Reservation System. The Fund is planned to operate at breakeven with any short-term timing surplus or deficit carried in the Group statement of financial position within working capital.

As all Fund income is designated for specific purposes and does not result in a profit or loss for the Group, the revenue recognition criteria as outlined in the accounting policy above are not met and therefore the income and expenses of the Fund are not included in the Group income statement.

The assets and liabilities relating to the Fund are included in the appropriate headings in the Group statement of financial position as the related legal, but not beneficial, rights and obligations rest with the Group. These assets and liabilities include the IHG Rewards Club liability, short-term timing surpluses and deficits and any receivables and payables related to the Fund.

The cash flows relating to the Fund are reported within ‘cash flow from operations’ in the Group statement of cash flows due to the close interrelationship between the Fund and the trading operations of the Group.

LOGO Further information on the Fund is included in note 32.

Loyalty programme – the hotel loyalty programme, IHG Rewards Club, enables members to earn points, funded through hotel assessments, during each qualifying stay at an IHG branded hotel and redeem points at a later date for free accommodation or other benefits. The future redemption liability is calculated by multiplying the number of points expected to be redeemed before they expire by the redemption cost per point. On an annual basis the Group engages an external actuary who uses statistical formulae to assist in the estimate of the number of points that will never be redeemed (‘breakage’).

Following the introduction of a points expiration policy in 2015, breakage has become more judgemental due to there being limited historical data on the impact of such a change. Actuarial gains and losses on the future redemption liability are borne by the System Fund and any resulting changes in the liability would correspondingly adjust the amount of short-term timing surpluses and deficits held in the Group statement of financial position.

At 31 December 2017, the future redemption liability was $760m (2016: $685m). Based on the conditions existing at the balance sheet date, a one percentage point decrease in the breakage estimate would increase this liability by approximately $10m.

Impairment testing – intangible assets with definite useful lives, and property, plant and equipment are tested for impairment when events or circumstances indicate that their carrying value may not be recoverable. Goodwill and intangible assets with indefinite useful lives are subject to an impairment test on an annual basis or more frequently if there are indicators of impairment. Assets that do not generate independent cash flows are combined into cash-generating units. Associates and joint ventures are tested for impairment when there is objective evidence that they might be impaired.

The impairment testing of individual assets or cash-generating units requires an assessment of the recoverable amount of the asset or cash-generating unit. If the carrying value of the asset or cash-generating unit exceeds its estimated recoverable amount, the asset or cash-generating unit is written down to its recoverable amount. Recoverable amount is the greater of fair value less costs of disposal and value in use. Value in use is assessed based on estimated future cash flows discounted to their present value using a pre-tax discount rate that is based on the Group’s weighted average cost of capital adjusted to reflect the risks specific to the business model and territory of the cash-generating unit or asset being tested. The outcome of such an assessment is subjective, and the result sensitive to the assumed future cash flows to be generated by the cash-generating units or assets and discount rates applied in calculating the value in use.

At 31 December 2017, the Group had goodwill of $237m (2016: $232m) and brands of $193m (2016: $193m), both of which are subject to annual impairment testing. Information on the impairment tests performed is included in note 13.

At 31 December 2017, the Group also had property, plant and equipment, other intangible assets and investments in associates and joint ventures with a net book value of $425m, $1,037m and $141m (2016: $419m, $867m and $111m) respectively. In 2017, an impairment charge of $18m (2016: $16m) was recognised in relation to an associate investment as described in detail in note 14. In respect of those other assets requiring an impairment test and depending on how recoverable amount was assessed, a 10% reduction in fair value or estimated future cash flows would have resulted in a further impairment charge of $13m.

New standards issued but not effective

The new and amended accounting standards discussed below are those which are expected to be relevant to the Group Financial Statements.

IFRS 15 ‘Revenue from Contracts with Customers’

IFRS 15 introduces a new five-step approach to measuring and recognising revenue from contracts with customers and will be adopted by the Group with effect from 1 January 2018. Under IFRS 15, revenue is recognised at an amount that reflects the consideration to which an entity expects to be entitled in exchange for transferring goods or services to a customer. Management’s assessment of the impact of IFRS 15 is substantially complete and a summary of the main changes and impacts on IHG are as follows:

1. Employee cost reimbursements

Under IFRS 15, the provision of employees to managed hotels is not considered to be a service that is distinct from the general hotel management service. Reimbursements for the costs of IHG employees working in managed hotels will therefore be shown as revenue with an equal matching cost, with no profit impact. Under current accounting, no revenue or matching cost is recognised.

2. Initial franchise and re-licensing fees

Under current accounting, application and re-licensing fees are recognised as revenue when billed as the monies received are not refundable and IHG has no further obligations to satisfy. Under IFRS 15, there is a requirement to consider whether the payment of these fees transfers a good or service to the customer that is distinct from the promise to provide franchise services. As this is not the case, IFRS 15 requires initial franchise and re-licensing fees to be recognised as franchise services are provided, over the life of the related contract. The spreading of these fees will result in an initial reduction to revenue and operating profit, and the recognition of deferred revenue on the balance sheet, reflecting the profile of increased amounts received in recent years.

3. Contract acquisition costs

Contract acquisition costs related to securing management and franchise contracts are currently charged to the income statement as incurred. Under IFRS 15, certain costs qualify to be capitalised as the cost of obtaining a contract and are amortised over the initial term of the related contract. This change results in an increase to operating profit and the capitalisation of contract costs on the balance sheet.

4. Amounts paid to hotel owners to secure management contracts and franchise agreements (‘Key money’)

Under current accounting, key money payments are capitalised as intangible assets and amortised over the life of the related contracts. Under IFRS 15, these payments are treated as consideration payable to a customer and therefore recognised as a deduction to revenue over the contract term. This change will result in a reduction to revenue, no change to operating profit, and the reclassification of key money on the balance sheet from intangible assets to contract assets.

5. Owned hotel disposals subject to a management contract

Under current accounting, when hotels are sold and the Group retains management of the hotel, the consideration recognised includes both the cash received and the fair value of the management contract which is capitalised as an intangible asset and subsequently amortised to the income statement. This accounting is governed by the ‘exchange of assets’ criteria included in IAS 16 ‘Property, Plant and Equipment’ and IAS 38 ‘Intangible Assets’. IFRS 15 specifically includes property sales in its scope and results in the sales consideration being recorded at the fair value of the encumbered hotel, which generally will be equivalent to the cash received. This change will result in the derecognition of historic intangible asset balances and a lower amortisation charge in the income statement.

6. System Fund revenues and expenses

The Group operates a System Fund (the Fund) to collect and administer cash assessments from hotel owners for the specific purpose of use in marketing, the guest reservation systems and hotel loyalty programme. The Fund also receives proceeds from the sale of loyalty points under third-party co-branding arrangements. The Fund is planned to break even and is managed for the benefit of hotels in the System with the objective of driving revenues for the hotels. Under current accounting, these receipts and expenses are not recorded in the Group income statement as set out on page 100.

Under IFRS 15, an entity is regarded as a principal if it controls a service prior to transfer to the customer. As marketing and reservations expenses primarily comprise payroll and marketing costs incurred under contracts entered into by the Group, management have determined that the Group controls these services. Fund revenues and expenses will therefore be recognised on a gross basis in the Group income statement. Assessment fees from hotel owners are generally levied as a percentage of hotel revenues and will be recognised as those hotel revenues occur.

In respect of the loyalty programme, the Group has determined that the related performance obligation is not satisfied in full until the member has redeemed the points at a participating hotel. Accordingly, revenue related to loyalty points earned by members or sold under co-brandingarrangements will be deferred in an amount that reflects the stand-alone selling price of the future benefit to the member. As materially all of the points will be redeemed at IHG managed or franchised hotels owned by third parties, IHG is deemed to be acting as agent on redemption and will therefore recognise the related revenue net of the cost of reimbursing the hotel that is providing the hotel stay. The deferred revenue balance under IFRS 15 will be significantly higher than the points redemption cost liability that is recognised under current accounting resulting in an increase in the Group’s net liabilities.

Management has also determined that in addition to the performance obligation for the redemption of points, co-branding arrangements contain other performance obligations including marketing services and the right to access the loyalty programme. Revenue attributable to the stand-alone selling price of these additional services is recognised over the term of the co-branding arrangement.

Certain travel agency commission revenues within the Fund will continue to be recognised on a net basis, where it has been determined that IHG acts as agent under IFRS 15.

7. System Fund surplus or deficit

Under current accounting, the Fund surplus or deficit is carried forward on the Group statement of financial position as set out on page 100. Under IFRS 15, the Fund surplus or deficit will be recognised in the Group income statement. Both the current accounting treatment and the change on applying IFRS 15, and the equivalent US GAAP standard, are consistent with current and expected future practice across the hotel industry. The Fund surplus of $158m at 31 December 2017 will be derecognised resulting in a reduction in the Group’s net liabilities.

The changes detailed in 6 and 7 above will result in an increase in recorded revenue and reduction in operating profit in 2017.

8. Presentation and disclosure

The presentation and disclosure requirements of IFRS 15 represent a significant change from current practice and will increase the volume of disclosures required in the notes to the financial statements.

9. Quantification of impacts

The Group will apply the full retrospective approach when transitioning to the new standard which will result in restated comparatives on the basis that IFRS 15 had always applied.

The estimated impacts of adjustments 1. to 5. on the 2017 results are as follows:

Impact	Group revenue $m			Group operating profit $m			Group net liabilities $m
1. Employee cost reimbursements		1,103			—			—
2. Initial franchise and re-licensing fees		(14	)		(14	)		(111	)
3. Contract acquisition costs		—			5			43
4. Key money		(17	)		—			—
5. Derecognition of management contracts		—			8			(192	)
Other		2			—			1
		1,074			(1	)		(259	)

The impact of deferring revenue in relation to the loyalty programme and recognising System Fund revenues and expenses in the Group income statement (items 6. and 7.) is expected to increase Group revenue by an additional $1.2bn. The impact on Group operating profit and Group net liabilities is still being assessed. The Group has an agreement with the IHG Owners Association to spend Fund income for the benefit of hotels in the IHG System such that the Group does not make a profit or loss from operating the Fund over the medium term.

IFRS 9 ‘Financial Instruments’

IFRS 9, which will be adopted by the Group with effect from 1 January 2018, introduces new requirements for classification and measurement of financial assets and financial liabilities, impairment and hedge accounting. Management’s assessment of the impact of IFRS 9 is substantially complete and a summary of the changes and impacts on IHG are as follows:

1. Financial assets at fair value through other comprehensive income

The Group holds equity investments which it currently classifies as available-for-sale financial assets. Changes in fair value are accumulated in equity and on disposal are recycled through the income statement. Under IFRS 9, these assets will be recorded at fair value through other comprehensive income with no recycling to the income statement.

IFRS 9 will not be applied to assets derecognised prior to 1 January 2018 and therefore there will be no change to the gain of $73m recognised on disposal of an available-for-sale equity investment in 2017 (see note 5).

2. Trade receivables and loans issued to hotel owners to secure

management contracts and franchise agreements Trade receivables, trade deposits and loans issued to hotel owners to secure management contracts and franchise agreements are held to collect contractual cash flows and are expected to give rise to cash flows representing solely payments of principal and interest. Management have therefore concluded that they continue to meet the criteria for amortised cost measurement under IFRS 9.

3. Impairment

The Group will apply the three-stage expected credit loss model introduced by IFRS 9 in respect of trade deposits and loans issued to hotel owners to secure management contracts and franchise agreements. The expected credit loss model is based on the concepts of ’12-month expected credit losses’ or ‘lifetime expected credit losses’ depending on the performance of the underlying asset. Management’s current assessments do not indicate any material change in impairment provisions as a result of IFRS 9.

The Group will apply the simplified version of the expected credit loss model permitted by IFRS 9 in respect of trade receivables, which involves assessing lifetime expected credit losses on all balances. To estimate the required impairment provision, management has assessed historical collection rates by geographical region, incorporating adjustments for future expectations. No material impact on the financial statements is expected from application of the expected credit loss model to trade receivables.

4. Hedge accounting

Management have determined that all existing hedge relationships that are currently designated effective hedging relationships will continue to qualify for hedge accounting under IFRS 9. As IFRS 9 does not change the general principles of how an entity accounts for effective hedges, applying the hedging requirements of IFRS 9 will not impact the Group Financial Statements.

5. Financial liabilities

Management’s initial assessments indicate no impact on the Group’s accounting for financial liabilities as the rules on classification and measurement of financial liabilities remain largely unchanged compared with IAS 39.

Except for hedge accounting, retrospective application of IFRS 9 is required. The new rules for hedge accounting will be applied prospectively in line with the requirements of the new standard. The Group does not plan to restate prior periods as allowed by the transition provisions of IFRS 9.

IFRS 16 ‘Leases’

The Group will adopt IFRS 16 with effect from 1 January 2019. The standard eliminates the classification of leases as either operating or finance leases and introduces a single accounting model which is similar to the current accounting model for finance leases under IAS 17.

Lessees will be required to recognise on the balance sheet ‘right-of-use’ assets which represent the right to use underlying assets during the lease term and a lease liability representing the minimum lease payment for all leases. Depreciation of ‘right-of-use’ assets and interest on lease liabilities will be charged to the income statement, replacing the corresponding operating lease rentals.

The Group will take the elections available under IFRS 16 not to apply the lease accounting model to leases which are considered low value or which have a term of less than 12 months.

The Group currently plans to apply the full retrospective method of application. Management are currently quantifying the impact of adopting IFRS 16 which is expected to result in an increase in lease liabilities of $350m–$400m at 31 December 2017, and an immaterial impact on profit after tax.

Other

From 1 January 2018, the Group will apply Amendments to IFRS 2 ‘Classification and Measurement of Share-Based Payment Transactions’. The amendments address the effects of vesting conditions on the measurement of cash-settled share-based payment transactions; the classification of a share-based payment transaction with net settlement features for withholding tax obligations and accounting where a modification to the terms and conditions of a share-based payment transaction changes its classification from cash-settled to equity-settled. Adoption of this amendment is not expected to have a material impact on the financial statements.

From 1 January 2019, the Group will apply the amendments to:

• IAS 28 ‘Investments in Associates and Joint Ventures’ relating to long-term interests to which the equity method is not applied;

• IFRS 9 ‘Financial Instruments’ relating to prepayment features with negative compensation;

• IFRIC 23 ‘Uncertainty over Income Tax Treatments’; and

• Other existing standards arising from the Annual Improvements to IFRSs 2015–2017 cycle.

The amendments are not expected to have a material impact on the Group’s reported financial performance or position.

1. Exchange rates

The results of operations have been translated into US dollars at the average rates of exchange for the year. In the case of sterling, the translation rate is $1=£0.78 (2016: $1=£0.74, 2015: $1=£0.65). In the case of the euro, the translation rate is $1=€0.89 (2016: $1=€0.90, 2015: $1=€0.90).

Assets and liabilities have been translated into US dollars at the rates of exchange on the last day of the year. In the case of sterling, the translation rate is $1=£0.74 (2016: $1=£0.81, 2015: $1=£0.68). In the case of the euro, the translation rate is $1=€0.83 (2016: $1=€0.95, 2015: $1=€0.92).

Segmental information

2. Segmental information

The management of the Group’s operations, excluding Central functions, is organised within four geographical regions:

• Americas;

• Europe;

• Asia, Middle East and Africa (AMEA); and

• Greater China.

These, together with Central functions, comprise the Group’s five reportable segments. No operating segments have been aggregated to form these reportable segments.

Central functions include costs of global functions including technology, sales and marketing, finance, human resources and corporate services; central revenue arises principally from technology fee income. Central liabilities include the loyalty programme liability and the cumulative System Fund surplus.

Each of the geographical regions is led by its own Chief Executive Officer and derives its revenues from either franchising, managing or owning hotels and additional segmental disclosures are provided accordingly.

Management monitors the operating results of the geographical regions and Central functions separately for the purpose of making decisions about resource allocation and performance assessment. Segmental performance is evaluated based on operating profit or loss and is measured consistently with operating profit or loss in the Consolidated Financial Statements, excluding exceptional items. Group financing activities and income taxes are managed on a group basis and are not allocated to reportable segments.

^a  Relates to the cost of integrating Kimpton into the operations of the Group, which has now been completed.

^b  In September 2017, the Group launched a comprehensive efficiency programme which will fund a series of new strategic initiatives to drive an acceleration in IHG’s future growth. The programme is centred around strengthening the Group’s organisational structure to redeploy resources to leverage scale in the highest opportunity markets and segments. The programme is expected to be completed in 2019. Included in the $36m cost are consultancy fees of $24m and severance costs of $8m. An additional $9m has been charged to the System Fund.

^c  Arose from changes to the Venezuelan exchange rate mechanisms and the adoption of the SIMADI exchange rate in 2015, this being the most accessible exchange rate open to the Group for converting its bolivar earnings into US dollars. The exceptional loss arose from the re-measurement of the Group’s bolivar assets and liabilities to the relevant exchange rate, being approximately $1=190VEF on adoption of SIMADI. Subsequent changes to the exchange rate mechanism have not resulted in material losses.

^d  Primarily legal costs related to development opportunities.

^e  In 2017, comprises a $7m (2016: $6m) deferred tax credit in respect of an associate investment impairment, a $6m (2016: $5m) deferred tax credit representing future tax relief on Kimpton integration costs, a $13m current tax credit in respect of reorganisation costs and a $28m current tax charge relating to the gain on disposal of Avendra (see note 15). In 2016, there was also a $1m credit in respect of other items. In 2015, comprised a charge of $56m relating to disposal of hotels, a credit of $21m in respect of the 2014 disposal of an 80.1% interest in InterContinental New York Barclay reflecting the judgement that state tax law changes would now apply to the deferred gain, and credits of $27m for current and deferred tax relief on other operating exceptional items of current and prior periods.

^f  Includes $108m relating to the impact of significant US tax reform that was enacted on 22 December 2017. This includes a current tax charge of $32m, relating predominantly to the Group’s estimated ‘transition tax’ liability on previously undistributed earnings of foreign subsidiaries of US entities, and a deferred tax credit of $140m, being principally the impact of the US federal tax rate reduction from 35% to 21% (effective 1 January 2018) on the Group’s US deferred tax liabilities, as well as the release of liabilities related to the Group’s undistributed post-acquisition earnings of subsidiaries that are no longer required as a result of the US transition tax. In addition, a deferred tax credit of $10m arises on the release of a contingency, previously charged as an exceptional item, which is no longer required due to statute of limitations expiry.

All items above relate to continuing operations.

LOGO The above items are treated as exceptional by reason of their size or nature, as further described on page 100.

Tax paid

Total net tax paid during the year of $172m (2016: $130m, 2015: $110m) comprises $147m (2016: $130m, 2015: $109m) paid in respect of operating activities and $25m (2016: $nil, 2015: $1m) paid in respect of investing activities. A reconciliation of tax paid to the total tax charge in the income statement follows:

	2017 $m			2016 $m			2015 $m
Current tax charge in the income statement		207			56			158
Current tax credit in the statement of comprehensive income		—			(12	)		(2	)

Tax paid per cash flow		172			130			110
Cash tax rate on total profitsc		25	%		22	%		8	%

^a  Tax contingency movements are included within the current tax charge but do not impact cash tax paid in the year.

^b  The timing difference in 2016 was predominantly in respect of the US where the payment regulations resulted in a large overpayment in the year.

^c  Calculated as total cash paid divided by total accounting profit before tax.

The cash tax rate of 8% for 2015 is low owing to the impact of exceptional accounting gains taxable on a deferred basis, without which the rate would have been 20% and thus broadly consistent with the cash tax rates for 2016 and 2017.

Current tax

Within current tax payable is $42m (2016: $39m) in respect of uncertain tax positions and offset against current tax receivable is $nil (2016: $5m) in respect of uncertain tax positions.

The calculation of the Group’s total tax charge involves consideration of applicable tax laws and regulations in many jurisdictions throughout the world. From time to time, the Group is subject to tax audits and uncertainties in these jurisdictions. The issues involved can be complex and disputes may take a number of years to resolve.

Where the interpretation of local tax law is not clear, management relies on judgement and accounting estimates to ensure all uncertain tax positions are adequately provided for in the Group Financial Statements. This may involve consideration of some or all of the following factors:

• Strength of technical argument, impact of case law and clarity of legislation;

• Professional advice;

• Experience of interactions, and precedents set, with the particular taxing authority; and

• Agreements previously reached in other jurisdictions on comparable issues.

The largest single contingency item within the current tax payable balance does not exceed $8m (2016: $8m).

^a  Primarily relates to provisions, accruals, amortisation and share-based payments.

^b  Movements largely reflect the impact of significant US tax reform enacted on 22 December 2017.

Deferred gains on investments represent tax which would crystallise upon a sale of a related joint venture, associate or other equity investment. The Group released its deferred tax provision (2016: $59m) in relation to temporary differences associated with post-acquisition undistributed earnings of subsidiaries largely as a result of the impact of the new US transition tax charge. Deferred gains on loan notes represent tax which is expected to fall due for payment in 2025 (2016: 2025). The deferred tax asset recognised in respect of losses of $40m (2016: $44m) is wholly in respect of revenue losses. A deferred tax asset of $2m (2016: $nil) is recognised in a legal entity which suffered a tax loss in the current or preceding period; this asset is recognised based on the profit forecast of the entity in question. Within deferred tax liabilities is $nil (2016: $10m) in respect of uncertain tax positions and offset against deferred tax assets is $5m (2016: $2m) in respect of uncertain tax positions.

The closing balance is further analysed by key territory as follows:

	Property, plant and equipment $m			Deferred gains on loan notes $m		Deferred gains on investments $m		Losses $m			Employee benefits $m			Intangible assets $m			Undistributed earnings of subsidiaries $m		Other short-term temporary differences $m			Total $m

Analysed as:
Deferred tax assets		(56	)		(48	)
Deferred tax liabilities		157			251
		101			203

The Group does not recognise deferred tax assets if it cannot anticipate being able to offset them against future profits or gains. The total unrecognised deferred tax position is as follows:

	Gross				Unrecognised deferred tax
	2017 $m		2016 $m		2017 $m		2016 $m
Revenue losses		452		518		76		94

^a  Primarily relates to provisions, accruals and amortisation.

There is no expiry date to any of the above unrecognised assets other than for the losses as shown in the table below:

No deferred tax liability has been recognised in respect of $0.5bn (2016: $0.9bn) of taxable temporary differences relating to subsidiaries (comprising undistributed earnings and net inherent gains) because the Group is in a position to control the timing of the reversal of these temporary differences and it is probable that such differences will not reverse in the foreseeable future.

Tax risks, policies and governance

LOGO Information concerning the Group’s tax governance can be found in the Taxation section of the Strategic Report on page 42.

Factors that may affect the future tax charge

Many factors will affect the Group’s future tax rate, the key ones being future legislative developments, future profitability of underlying subsidiaries and tax uncertainties.

There are many potential future changes to worldwide taxation systems as a result of the potential adoption by individual territories of recommendations of the OECD’s Base Erosion and Profit Shifting project, and other similar initiatives being driven by governments and tax authorities. The Group continues to monitor activity in this area.

Significant US tax reform was enacted on 22 December 2017, which notably included a reduction in the US federal tax rate from 35% to 21%, with effect from 1 January 2018 for IHG. Although most of the new provisions only take effect from 2018, some aspects have a direct impact on the Group’s 2017 position and are detailed in note 5. The Group continues to evaluate the impact of the provisions that will take effect during 2018, noting that new regulations and guidance on US state and federal tax are anticipated to be released during the year. At this stage, we are anticipating an overall Group tax rate reduction of mid to high single digit percentage points for 2018 onwards.

Rules restricting UK loss usage and interest deductibility were enacted in 2017. These rules will increase the amount of UK cash tax paid in the near future, although this is not expected to be significant in the context of the Group’s overall cash tax payable. The forthcoming reduction to the UK corporation tax rate (to 17%, effective 1 April 2020) is not expected to have a material effect on the Group.

Earnings per ordinary share

9. Earnings per ordinary share

Basic earnings per ordinary share is calculated by dividing the profit for the year available for IHG equity holders by the weighted average number of ordinary shares, excluding investment in own shares, in issue during the year.

Diluted earnings per ordinary share is calculated by adjusting basic earnings per ordinary share to reflect the notional exercise of the weighted average number of dilutive ordinary share awards outstanding during the year.

Adjusted earnings per ordinary share is disclosed in order to show performance undistorted by exceptional items, to give a more meaningful comparison of the Group’s performance.

The Group’s property, plant and equipment mainly comprises hotels, but also offices and computer hardware, throughout the world. 43% (2016: 44%) of the net book value relates to the largest owned and leased hotel, of a total of eight open hotels (2016: eight open hotels). At 31 December 2017 and 31 December 2016, there were no hotels under construction.

The carrying value of property, plant and equipment held under finance leases at 31 December 2017 was $181m (2016: $182m).

26% (2016: 25%) of hotel properties by net book value were directly owned, with 57% (2016: 58%) held under leases having a term of 50 years or longer.

Due to localised adverse market conditions, an impairment charge of $27m was recognised during 2015 relating to two hotels in North America following a re-assessment of their recoverable amounts to $37m, based on value in use calculations. Estimated future cash flows were discounted at a pre-tax rate of 11.75%. All impairment charges are included within ‘impairment charges’ on the face of the Group income statement.

Goodwill and brands

During 2015, the Group acquired Kimpton (see note 10) resulting in the recognition of goodwill of $167m and brands of $193m, together with management contracts of $71m.

The Kimpton brands are considered to have an indefinite life given their strong brand awareness and reputation in the upscale boutique hotel sector, and management’s commitment to continued investment in their growth. The brands are protected by trademarks and there are not believed to be any legal, regulatory or contractual provisions that limit the useful lives of the brands. In the hotel industry there are a number of brands that have existed for many years and IHG has brands that are over 60 years old.

The Group tests goodwill and indefinite life intangible assets for impairment annually, or more frequently if there are any indicators that an impairment may have arisen. The year-end carrying value of goodwill and indefinite life brands have been allocated to cash-generating units (CGUs) for impairment testing purposes as follows:

	2017				2016
	Goodwill $m		Brands $m		Goodwill $m		Brands $m
CGU

Europe Franchised		10		—		10		—
AMEA Managed and Franchised		106		—		101		—
		237		193		232		193

The recoverable amounts of the CGUs are determined from value in use calculations. These calculations include a three-year period using pre-tax cash flow forecasts derived from the most recent financial budgets approved by management, incorporating growth rates based on management’s past experience and industry growth forecasts. The key assumptions that underpin the financial budgets are RevPAR growth and net System size growth. Cash flows beyond the three-year period are extrapolated using terminal growth rates that do not exceed the average long-term growth rates for the relevant markets. A 10% contingency factor is applied to reduce all cash flow projections before being discounted using pre-tax rates that are based on the Group’s weighted average cost of capital adjusted to reflect the risks specific to the business model and territory of the CGU being tested.

The terminal growth rates and discount rates used, which are considered to be key assumptions, are as follows:

	Terminal growth rate				Discount rate
	2017 %		2016 %		2017 %		2016 %
Americas Managed		2.0		2.0		10.4		9.8
Americas Franchised		2.0		2.0		9.4		8.8
Europe Managed		2.0		2.0		10.8		9.3
Europe Franchised		2.0		2.0		9.8		8.4
AMEA Managed and Franchised		3.5		3.5		14.1		13.0

Impairment was not required at either 31 December 2017 or 31 December 2016.

Given the contingency factor applied to the cash flow projections and the significant amounts by which the recoverable amounts of the CGUs exceed their carrying amounts, management have determined that impairment charges would not arise from reasonably possible changes in the key assumptions.

Software

Software includes $234m relating to the development of the next-generation Guest Reservation System with Amadeus. The asset was not amortised during the year as the roll-out to hotels is expected to commence in 2018.

Substantially all software additions are internally developed.

Management contracts

In addition to the management contracts acquired with the Kimpton acquisition in 2015 (see note 10), management contracts relate to contract values recognised as part of the proceeds for hotels sold.

At 31 December 2017, the net book value and remaining amortisation period of the principal management contracts were as follows:

	2017				2016
	Net book value $m		Remaining amortisation period Years		Net book value $m		Remaining amortisation period Years

InterContinental London Park Lane		31		45		29		46
InterContinental Paris – Le Grand		34		47		31		48

The weighted average remaining amortisation period for all management contracts is 30 years (2016: 31 years).

All associates and joint ventures are accounted for using the equity method.

During 2016, an investment for which the Group has a 30% interest was transferred to other financial assets following loss of significant influence over the operating and financial policy decisions of the entity.

The impairment charges of $18m and $16m in 2017 and 2016 respectively, relate to the Barclay associate (see following page) and result from the currently depressed trading outlook for the New York hotel market and the high costs of renovating the hotel. The recoverable amount of the investment has been measured at its fair value less costs of disposal, based on the Group’s share of the market value of the hotel less debt in the associate. The hotel was appraised by a professional external valuer using an income capitalisation approach which is a discounted cash flow technique that measures the present value of projected income flows (over a 10-year period) and the reversion of the property sale. Within the fair value hierarchy, this is categorised as a Level 3 fair value measurement. In addition to the projected income flows, the key assumptions used were a discount rate of 7.3% (2016: 7.3%) and a terminal capitalisation rate of 6.3% (2016: 6.0%).

Due to localised adverse market conditions, an impairment charge of $9m was recognised during 2015 relating to an associate investment in the AMEA region following a re-assessment of its recoverable amount to $nil, based on value in use calculations. Estimated future cash flows were discounted at a pre-tax rate of 13.2%. During 2017, the investment was disposed of for $nil proceeds.

On 20 November 2015, the Group disposed of an associate investment in the AMEA region realising a gain on disposal of $9m. At the time of disposal, the investment had a $nil net book value.

Barclay associate

The Group held one material associate investment at 31 December 2017, a 19.9% interest in 111 East 48th Street Holdings, LLC (the Barclay associate) which owns InterContinental New York Barclay (the hotel), a hotel managed by the Group. The hotel reopened for trading in April 2016 following a major renovation. The investment is classified as an associate and equity accounted. Whilst the Group has the ability to exercise significant influence through certain decision rights, approval rights relating to the hotel’s operating and capital budgets rest solely with the 80.1% majority member. The Group’s ability to receive cash dividends is dependent on the hotel generating sufficient income to satisfy specified owner returns.

In March 2017, the Group invested $43m in the Barclay associate in conjunction with a refinancing of the hotel. The cash was used to repay a $43m supplemental bank loan for which the Group had previously provided an indemnity for 100% of the related obligations. As a consequence, the indemnity has been extinguished.

Equity securities available-for-sale are measured at fair value (see note 23) and loans and receivables are held at amortised cost.

Equity securities available-for-sale were denominated in the following currencies: US dollars $93m (2016: $121m), Hong Kong dollars $25m (2016: $24m) and other currencies $9m (2016: $11m). Unlisted equity shares are mainly investments in entities that own hotels which the Group manages. Dividend income from available-for-sale equity securities of $10m (2016: $7m) is reported as ‘other operating income and expenses’ in the Group income statement.

On 13 December 2017, the sale of Avendra, LLC (Avendra) to Aramark Services, Inc., resulted in the Group receiving cash proceeds of $75m from its 6.29% interest in Avendra and the recording of a $73m exceptional gain in the Group income statement (see note 5). Prior to the sale, the Group’s investment in Avendra was included in unquoted equity securities available-for-sale. Avendra is a North American hospitality procurement services provider.

Trade deposits and loans include deposits of $66m made to a hotel owner in connection with a portfolio of management contracts. The deposits are non-interest-bearing and repayable at the end of the management contract terms, and are therefore held at a discounted value of $28m (2016: $19m); the discount unwinds to the income statement within ‘financial income’ over the period to repayment.

Restricted funds comprise cash ring-fenced to satisfy insurance claims.

The bank accounts pledged as security (£31m) are subject to a charge in favour of the members of the UK unfunded pension arrangement (see note 25).

The movement in the provision for impairment of other financial assets during the year is as follows:

	2017 $m			2016 $m
At 1 January		(22	)		(28	)
Disposals		4			6
At 31 December		(18	)		(22	)

The provision is used to record impairment losses unless the Group is satisfied that no recovery of the amount is possible; at that point the amount considered irrecoverable is either written off directly to the income statement or, if previously provided, against the financial asset with no impact on the income statement.

Cash at bank and in hand includes bank balances of $116m (2016: $91m) which are matched by bank overdrafts of $110m (2016: $89m) under the Group’s cash pooling arrangements. Under these arrangements, each pool contains a number of bank accounts with the same financial institution and the Group pays interest on net overdraft balances within each pool. The cash pools are used for day-to-day cash management purposes and are managed as closely as possible to a zero balance on a net basis for each pool. Overseas subsidiaries are typically in a cash-positive position with the matching overdrafts held by the Group’s central treasury company in the UK.

For the purposes of the Group statement of cash flows, cash and cash equivalents comprise the following:

Unsecured bank loans

Unsecured bank loans are borrowings under the Group’s Syndicated and Bilateral Facilities. Amounts are classified as non-current when the facilities have more than 12 months to expiry.

The Syndicated Facility comprises a $1,275m five-year revolving credit facility maturing in March 2022.

The Bilateral Facility comprises a $75m revolving credit facility maturing in March 2022. The Bilateral Facility contains the same terms and covenants as the Syndicated Facility.

A variable rate of interest is payable on amounts drawn under both facilities, which was 2.15% at 31 December 2017.

Finance lease obligations

Finance lease obligations, which relate primarily to the 99-year lease (of which 88 years remain) on the InterContinental Boston hotel, are payable as follows:

Financial risk management

22. Financial risk management

Overview

The Group is exposed to financial risks that arise in relation to underlying business activities. These risks include: foreign exchange risk, liquidity risk, interest rate risk, credit risk and capital risk. There are Board approved policies in place to manage these risks. Treasury activities to manage these risks may include money market investments, repurchase agreements, spot and forward foreign exchange instruments, currency swaps, interest rate swaps and forward rate agreements.

Foreign exchange risk

The US dollar is the predominant currency of the Group’s revenue and cash flows. Movements in foreign exchange rates can affect the Group’s reported profit, net liabilities and interest cover. The most significant exposures of the Group are in currencies that are freely convertible. The Group’s reported debt has an exposure to borrowings held in pounds sterling.

Foreign exchange hedging

From time to time, the Group hedges a portion of forecast foreign currency income by taking out forward exchange contracts. The designated risk is the spot foreign exchange risk. There were no such contracts in place at either 31 December 2017 or 31 December 2016.

The Group also uses short-dated foreign exchange swaps to manage sterling surplus cash and reduce US dollar borrowings whilst maintaining operational flexibility. At 31 December 2017, the Group held short-dated foreign exchange swaps with principals of $30m (2016: $120m).

The fair value of these derivative financial instruments at 31 December 2017 was $nil (2016: $3m liability).

Hedge of net investment in foreign operations

Wherever possible, the Group matches the currency of its debt (either directly or via derivatives) to the currency of its net assets, whilst maximising the amount of US dollars borrowed to reflect the predominant trading currency. However US dollars are only borrowed to the extent that hedge accounting can be achieved.

The Group designates certain foreign currency bank borrowings and currency derivatives as net investment hedges of foreign operations. The designated risk is the spot foreign exchange risk for loans and short-dated derivatives. The interest on these financial instruments is taken through financial income or expense.

The maximum amount of foreign exchange derivatives held during the year as net investment hedges and measured at calendar quarter ends were short-dated foreign exchange swaps with principals of $160m (2016: $325m).

Hedge effectiveness is measured at calendar quarter ends. No ineffectiveness arose in respect of the Group’s net investment hedges during the current or prior year.

22. Financial risk management continued

Interest rate risk

The Group is exposed to interest rate risk in relation to its fixed and floating rate borrowings. The Group’s policy requires a minimum of 50% fixed rate debt over the next 12 months. With the exception of overdrafts, 86% of borrowings were fixed rate debt at 31 December 2017 (2016: 93%).

Interest rate hedging

If required, the Group uses interest rate swaps to manage the exposure. The Group designates interest rate swaps as cash flow hedges. No interest rate swaps were used during 2017, 2016 or 2015.

Interest and foreign exchange risk sensitivities

The following table shows the impact of a general strengthening in the US dollar against sterling and euro on the Group’s profit before tax and net liabilities, and the impact of a rise in US dollar, euro and sterling interest rates on the Group’s profit before tax.

		2017 $m			2016 $m			2015 $m
Increase/(decrease) in profit before tax
Sterling: US dollar exchange rate	5¢ fall		4.0			5.2			4.8
Euro: US dollar exchange rate	5¢ fall		(2.1	)		(2.2	)		(1.9	)
US dollar interest rates	1% increase		(2.9	)		(1.8	)		(0.9	)
Sterling interest rates	1% increase		0.3			1.3			7.9
Decrease/(increase) in net liabilities
Sterling: US dollar exchange rate	5¢ fall		44.1			47.2			23.7
Euro: US dollar exchange rate	5¢ fall		(4.1	)		(5.5	)		(7.6	)

The impact of a weakening in the US dollar or a fall in interest rates would be the reverse of the above values.

Interest rate sensitivities are calculated based on the year-end net debt position.

Liquidity risk

The Group policy ensures sufficient liquidity is maintained to meet all foreseeable medium-term cash requirements and provide headroom against unforeseen obligations.

Cash and cash equivalents is held in short-term deposits and cash funds which allow daily withdrawals of cash. Most of the Group’s funds are held in the UK or US, although $3m (2016: $3m) is held in countries where repatriation is restricted as a result of foreign exchange regulations.

Medium and long-term borrowing requirements are met through committed bank facilities and bonds as detailed in note 20. Short-term borrowing requirements may be met from drawings under uncommitted overdrafts and facilities.

The Syndicated and Bilateral Facilities contain two financial covenants: interest cover and net debt divided by earnings before interest, tax, depreciation and amortisation (EBITDA). The Group has been in compliance with all of the financial covenants in its loan documents throughout the year and expects to continue to have significant headroom for the foreseeable future.

The following are the undiscounted contractual cash flows of financial liabilities, including interest payments:

Trade and other payables above includes the cash flows relating to the future redemption liability of the Group’s loyalty programme. The repayment profile has been determined by actuaries based on expected redemption profiles and could in reality be different from expectations.

Credit risk

Credit risk on treasury transactions is minimised by operating a policy on the investment of surplus cash that generally restricts counterparties to those with a BBB credit rating or better or those providing adequate security. The Group uses long-term credit ratings from Standard and Poor’s, Moody’s and Fitch Ratings as a basis for setting its counterparty limits.

In order to manage the Group’s credit risk exposure, the treasury function sets counterparty exposure limits using metrics including credit ratings, the relative placing of credit default swap pricings, tier 1 capital and share price volatility of the relevant counterparty.

The Group trades only with recognised, creditworthy third parties. It is the Group’s policy that all customers who wish to trade on credit terms are subject to credit verification procedures.

In respect of credit risk arising from financial assets, the Group’s exposure to credit risk arises from default of the counterparty, with a maximum exposure equal to the carrying amount of these instruments.

The carrying amount of financial assets represents the maximum exposure to credit risk.

Capital risk management

The Group manages its capital to ensure that it will be able to continue as a going concern. The capital structure consists of net debt, issued share capital and reserves totalling $993m at 31 December 2017 (2016: $739m). The structure is managed to maintain an investment grade credit rating, to provide ongoing returns to shareholders and to service debt obligations, whilst maintaining maximum operational flexibility. A key characteristic of IHG’s managed and franchised business model is that it is highly cash generative, with a high return on capital employed. Surplus cash is either reinvested in the business, used to repay debt or returned to shareholders. The Group’s debt is monitored on the basis of a cash flow leverage ratio, being net debt divided by EBITDA, with the objective of maintaining an investment grade credit rating.

^a  Financial assets and liabilities which are measured at fair value.

There are no other assets or liabilities measured at fair value on a recurring or non-recurring basis, or for which fair value is disclosed, other than as described in note 14.

The fair value of cash and cash equivalents and bank overdrafts approximates book value due to the short maturity of the investments and deposits, and the fair value of other financial assets approximates book value based on prevailing market rates. The fair value of the unsecured bank loans approximates book value as interest rates reset to market rates on a frequent basis. The fair value of trade and other receivables, trade and other payables, the future redemption liability of the Group’s loyalty programme and current provisions approximates to their carrying value.

Fair value hierarchy

The following table provides the fair value measurement hierarchy of the above assets and liabilities, other than those with carrying amounts which are reasonable approximations of their fair values:

Level 1: quoted (unadjusted) prices in active markets for identical assets or liabilities.

Level 2: other techniques for which all inputs which have a significant effect on fair value are observable, either directly or indirectly.

Level 3: techniques which use inputs which have a significant effect on the recorded fair value that are not based on observable market data.

There were no transfers between Level 1 and Level 2 fair value measurements during the year and no transfers into and out of Level 3.

The fair value of quoted equity shares and the bonds is based on their quoted market price.

Derivatives are fair valued using discounted future cash flows, taking into consideration exchange rates prevailing on the last day of the reporting period and interest rates from observable swap curves.

Finance lease obligations relate primarily to the lease of InterContinental Boston, which is fair valued by discounting the future cash flows payable under the loan, which are fixed, at a risk adjusted long-term interest rate. The interest rate used to discount the cash flows at 31 December 2017 was 6.9% (2016: 7.2%).

Unquoted equity shares are fair valued using the International Private Equity and Venture Capital Valuation Guidelines either by applying an average price-earnings (P/E) ratio for a competitor group to the earnings generated by the investment or by reference to share of net assets if the investment is currently loss-making or a recent property valuation is available. The average P/E ratio for the year was 30.7 (2016: 24.5) and a non-marketability factor of 30% (2016: 30%) is applied. A 10% increase in the average P/E ratio would result in a $2m increase (2016: $2m) in the fair value of the investments and a 10% decrease in the average P/E ratio would result in a $2m decrease (2016: $2m) in the fair value of the investments. A 10% increase in net assets would result in a $7m increase (2016: $7m) in the fair value of the investments and a 10% decrease in net assets would result in a $7m decrease (2016: $7m) in the fair value of the investments.

Retirement benefits

25. Retirement benefits

UK

Since 6 August 2014, UK retirement and death in service benefits are provided for eligible employees by the IHG UK Defined Contribution Pension Plan. Members, including those who have been auto-enrolled since 1 September 2013, are provided with defined contribution arrangements under this plan; benefits are based on each individual member’s personal account. The plan is HM Revenue and Customs registered and governed by an independent trustee, assisted by professional advisers as and when required. The overall operation of the plan is subject to the oversight of The Pensions Regulator.

The former defined benefit plan, the InterContinental Hotels UK Pension Plan, was wound up on 21 July 2015 following the completion of the buy-out and transfer of the defined benefit obligations to Rothesay Life on 31 October 2014.

Residual defined benefit obligations remain in respect of additional benefits provided to members of an unfunded pension arrangement who were affected by lifetime or annual allowances under the former defined benefit arrangements. Accrual under this arrangement ceased with effect from 1 July 2013 and a cash-out offer in 2014 resulted in the extinguishment of approximately 70% of the unfunded pension obligations. The Company meets the benefit payment obligations of the remaining members as they fall due. A charge over certain ring-fenced bank accounts totalling £31m at 31 December 2017 (see note 15) is currently held as security on behalf of the remaining members.

US

The Group also maintains the following US-based defined benefit plans: the funded Inter-Continental Hotels Pension Plan (the Plan), unfunded Inter-Continental Hotels Non-qualified Pension Plans and unfunded Inter-Continental Hotels Corporation Postretirement Medical, Dental, Vision and Death Benefit Plan. All plans are closed to new members. In respect of the Plan, an Investment Committee has responsibility for the oversight and management of the Plan’s assets, which are held in a separate trust. The Committee comprises senior Company employees and is assisted by professional advisers as and when required.

During 2016, the Group made a funding contribution of $32m to the Plan which enabled it to achieve full funding. The assets of the Plan were subsequently invested in liability-matching assets. In November 2017, the Company received approval from the Internal Revenue Service to proceed with a plan termination and distribution of the assets from the Plan in 2018. This will involve certain members being offered lump-sum payments with remaining plan interests subject to the expected purchase of annuity contracts.

During 2015, the Group made a lump sum cash-out offer to the terminated vested members of the Inter-Continental Hotels Pension Plan. Members accepting the offer received lump sum cash payments totalling $11m on 1 November 2015.

Other

The Group also operates a number of smaller pension schemes outside the UK, the most significant of which is a defined contribution scheme in the US; there is no material difference between the pension costs of, and contributions to, these schemes.

In respect of the defined benefit plans, the amounts recognised in the Group income statement, in ‘administrative expenses’, are:

Assumptions

The principal financial assumptions used by the actuaries to determine the benefit obligations are:

	Pension plans
	UK						US						US Post-employment benefits
	2017 %		2016 %		2015 %		2017 %		2016 %		2015 %		2017 %		2016 %		2015 %

Discount rate		2.6		2.7		4.0		3.3		3.7		3.9		3.3		3.8		3.9
Inflation rate		3.2		3.3		3.2		—		—		—		—		—		—
Healthcare cost trend rate assumed for next year:
Pre-65 (ultimate rate reached in 2025)														7.7		7.0		7.5
Post-65 (ultimate rate reached in 2024)														8.7		8.3		9.0
Ultimate rate that the cost trend rate trends to														4.5		4.5		4.5

Mortality is the most significant demographic assumption. The current assumptions for the UK are based on the S2PA ‘light’ year of birth tables with projected mortality improvements using the CMI_2016 model and a 1.25% per annum long-term trend with age rated down by 0.7 and 2.3 years for pensioners and 0.5 and 2.6 years for non-pensioners, male and female respectively. In the US, the current assumptions are based on the RP-2014 Employee/Healthy Annuitant Generationally Projected with Scale MP-2017 mortality tables.

In both the UK and US, the assumptions have been revised during the year to reflect life expectancy at retirement age as follows:

	Pension plans
	UK						US
	2017 Years		2016 Years		2015 Years		2017 Years		2016 Years		2015 Years
Current pensioners at 65a         —   male		24		24		26		21		21		21
—   female		26		26		29		23		23		23
Future pensioners at 65b           —   male		25		25		28		22		22		23
—   female		28		28		31		24		24		25

^a  Relates to assumptions based on longevity (in years) following retirement at the end of the reporting period.

^b  Relates to assumptions based on longevity (in years) relating to an employee retiring in 2037.

The assumptions allow for expected increases in longevity.

Sensitivities

Changes in assumptions used for determining retirement benefit costs and obligations may have a material impact on the income statement and the statement of financial position. The key assumptions are the pension increases, discount rate, the rate of inflation and the assumed mortality rate. The sensitivity analysis below is based on extrapolating reasonable changes in these assumptions, using year-end conditions and assuming no interdependency between the assumptions.

		UK						US
		Higher/ (lower) pension cost $m			Increase/ (decrease) in liabilities $m			Higher/ (lower) pension cost $m			Increase/ (decrease) in liabilities $m
Pensions increases	—   0.25% decrease		(0.1	)		(1.1	)		—			—
	—   0.25% increase		—			1.4			—			—
Discount rate	—   0.25% decrease		(0.1	)		1.5			(0.1	)		2.9
	—   0.25% increase		—			(1.4	)		—			(2.7	)
Inflation rate	—   0.25% increase		—			1.4			—			—
	—   0.25% decrease		(0.1	)		(1.1	)		—			—
Mortality rate	—   One year increase		—			0.8			0.2			9.7

A one percentage point increase in assumed healthcare costs trend rate would increase the accumulated post-employment benefit obligations as at 31 December 2017 by $1.9m (2016: $1.9m, 2015: $2.0m) and a one percentage point decrease would decrease the obligations by $1.8m (2016: $1.7m, 2015: $1.8m).

Annual Performance Plan

Under the IHG Annual Performance Plan (APP), eligible employees (including Executive Directors) can receive all or part of their bonus in the form of deferred shares and/or receive one-off awards of shares. Deferred shares are released on the third anniversary of the award date. Under the terms of awards that are referred to in this note, a fixed percentage of the award is made in the form of shares. Awards under the APP are conditional on the participants remaining in the employment of a participating company or leaving for a qualifying reason as per the plan rules. The award of deferred shares under the APP is at the discretion of the Remuneration Committee.

The number of shares is calculated by dividing a specific percentage of the participant’s annual performance-related award by the middle market quoted prices on the three consecutive dealing days immediately preceding the date of grant. A number of executives participated in the APP during the year and conditional rights over 234,918 (2016: 335,775, 2015: 265,285) shares were awarded to participants. In 2017 this number included 79,471 (2016: 103,071, 2015: 58,338) shares awarded as part of recruitment terms or for one-off individual awards.

New plan rules for the APP were approved by shareholders at the AGM on 2 May 2014, and apply to awards made in respect of the 2015 and subsequent financial years. The new plan rules contain substantially the same terms as the superseded plan rules.

Long Term Incentive Plan

The Long Term Incentive Plan (LTIP) allows Executive Directors and eligible employees to receive conditional share awards, which normally have a vesting period of three years.

Performance-related awards: Awards to the Executive Directors, and some awards to other eligible employees, are granted subject to the achievement of performance conditions set by the Remuneration Committee, which are normally measured over the vesting period.

Restricted stock units: Awards to eligible employees are granted subject to continued employment.

Awards are normally made annually and, except in exceptional circumstances, will not exceed three times salary for eligible employees. The plan provides for the grant of ‘nil cost options’ to participants as an alternative to conditional share awards. During the year, conditional rights over 805,045 (2016: 1,355,721, 2015: 1,803,308) shares were awarded to employees under the plan, comprising 280,458 (2016: 888,518, 2015: 1,803,308) performance-related awards and 524,587 (2016: 467,203, 2015: nil) restricted stock units.

New plan rules for the LTIP were approved by shareholders at the AGM on 2 May 2014, and apply to awards made in respect of the 2015-17 and subsequent LTIP cycles. The new plan rules contain substantially the same terms as the superseded plan rules.

LOGO More detailed information on the performance measures for awards to Executive Directors is shown in the Directors’ Remuneration Report on pages 64 to 77.

The Group recognised a cost of $21m (2016: $17m, 2015: $19m) in operating profit and $2m (2016: $nil, 2015: $nil) within exceptional administrative expenses related to equity-settled share-based payment transactions during the year, net of amounts borne by the System Fund.

No aggregate consideration was received in respect of ordinary shares issued under option schemes during 2017, 2016 or 2015.

The Group uses separate option pricing models and assumptions depending on the plan. The following table sets out information about awards granted in 2017, 2016 and 2015:

The authority given to the Company at the AGM held on 5 May 2017 to purchase its own shares was still valid at 31 December 2017. A resolution to renew the authority will be put to shareholders at the AGM on 4 May 2018.

The Company no longer has an authorised share capital.

On 23 February 2016, the Group announced a $1.5bn return of funds to shareholders by way of a special dividend and share consolidation. On 6 May 2016, shareholders approved the share consolidation on the basis of 5 new ordinary shares of 18³¹⁸/₃₂₉p per share for every 6 existing ordinary shares of 15²⁶⁵/₃₂₉p, which became effective on 9 May 2016. The special dividend was paid to shareholders on 23 May 2016. The dividend and share consolidation had the same economic effect as a share repurchase at fair value, therefore previously reported earnings per share has not been restated.

On 21 February 2017, the Group announced a $400m return of funds to shareholders by way of a special dividend and share consolidation. On 5 May 2017, shareholders approved the share consolidation on the basis of 45 new ordinary shares of 19¹⁷/₂₁p per share for every 47 existing ordinary shares of 18³¹⁸/₃₂₉p, which became effective on 8 May 2017. The special dividend was paid to shareholders on 22 May 2017. The dividend and share consolidation had the same economic effect as a share repurchase at fair value, therefore previously reported earnings per share has not been restated.

The balance classified as equity share capital includes the total net proceeds (both nominal value and share premium) on issue of the Company’s equity share capital, comprising 19¹⁷/₂₁p shares. The share premium reserve represents the amount of proceeds received for shares in excess of their nominal value.

The nature and purpose of the other reserves shown in the Group statement of changes in equity on pages 90 to 92 of the Financial Statements is as follows:

Capital redemption reserve

This reserve maintains the nominal value of the equity share capital of the Company when shares are repurchased or cancelled.

Shares held by employee share trusts

Comprises $5.4m (2016: $10.5m, 2015: $18.3m) in respect of 0.2m (2016: 0.3m, 2015: 0.5m) InterContinental Hotels Group PLC ordinary shares held by employee share trusts, with a market value at 31 December 2017 of $12.1m (2016: $15.0m, 2015: $19.8m).

Other reserves

Comprises the merger and revaluation reserves previously recognised under UK GAAP, together with the reserve arising as a consequence of the Group’s capital reorganisation in June 2005. Following the change in presentational currency to the US dollar in 2008, this reserve also includes exchange differences arising on retranslation to period-end exchange rates of equity share capital, the capital redemption reserve and shares held by employee share trusts.

Unrealised gains and losses reserve

This reserve records movements in the fair value of available-for-sale financial assets and the effective portion of the cumulative net change in the fair value of the cash flow hedging instruments related to hedged transactions that have not yet occurred.

Currency translation reserve

This reserve records the movement in exchange differences arising from the translation of foreign operations and exchange differences on foreign currency borrowings and derivative instruments that provide a hedge against net investments in foreign operations. On adoption of IFRS, cumulative exchange differences were deemed to be $nil as permitted by IFRS 1.

The fair value of derivative instruments designated as hedges of net investments in foreign operations outstanding at 31 December 2017 was $nil (2016: $3m net liability, 2015: $3m net liability).

Treasury shares

During 2017, 0.9m (2016: 0.9m) treasury shares were transferred to the employee share trusts. As a result of the 2017 share consolidation, the number of shares held in treasury reduced by 0.4m (2016: reduced by 1.7m as a result of the 2016 share consolidation). At 31 December 2017, 7.6m shares (2016: 8.9m, 2015: 11.5m) with a nominal value of $2.0m (2016: $2.1m, 2015: $2.7m) were held as treasury shares at cost and deducted from retained earnings.

Non-controlling interest

A non-controlling interest is equity in a subsidiary of the Group not attributable, directly or indirectly, to the Group. Non-controlling interests are not material to the Group.

Operating leases

28. Operating leases

During the year ended 31 December 2017, $86m (2016: $84m, 2015: $77m) was recognised as an expense in the Group income statement in respect of operating leases, net of amounts borne directly by the System Fund. The expense includes contingent rents of $32m (2016: $32m, 2015: $29m). $2m (2016: $2m, 2015: $3m) was recognised as income from sub-leases.

Future minimum lease payments under non-cancellable operating leases are as follows:

	2017 $m		2016 $m
Due within one year		56		53
One to two years		46		49
Two to three years		45		43
Three to four years		60		41
Four to five years		30		58
More than five years		297		346
		534		590

In addition, in certain circumstances the Group is committed to making additional lease payments that are contingent on the performance of the hotels that are being leased.

The average remaining term of these leases, which generally contain renewal options, is approximately 15 years (2016: 17 years). No material restrictions or guarantees exist in the Group’s lease obligations.

Total future minimum rentals expected to be received under non-cancellable sub-leases are $4m (2016: $4m).

Contingencies and guarantees

30. Contingencies and guarantees

Security incidents

In 2016, the Group was notified of (a) a security incident at a number of Kimpton hotels that resulted in unauthorised access to guest payment card data (the Kimpton Security Incident), and (b) a security incident that involved malware being installed on servers that processed payment cards used at restaurants and bars of 12 IHG managed properties (the Americas Security Incident), together the Security Incidents. A provision of $5m was made at 31 December 2016, and remains in place at 31 December 2017 (see note 19), to cover the estimated cost of reimbursing the impacted card networks for counterfeit fraud losses and related expenses. At 31 December 2017, this estimate relates to both the Kimpton and Americas Security Incidents whereas at 31 December 2016 it was Kimpton related only. The estimates continue to involve significant judgement based on currently available information and remain subject to change as actual claims are made and new information comes to light.

The Group may be exposed to investigations regarding compliance with applicable State and Federal data security standards, and legal action from individuals and organisations impacted by the Security Incidents. Due to the general nature of the regulatory enquiries received and class action filings to date, it is not practicable to make a reliable estimate of the possible financial effects of any such claims on the Group at this time. To date, four lawsuits have been filed against IHG entities relating to the Security Incidents, all of which are in the early stages of litigation.

In respect of the $5m provision, it is expected that a proportion will be recoverable under the Group’s insurance programmes although this, together with any potential recoveries in respect of the contingent liabilities detailed above, will be subject to specific agreement with the relevant insurance providers.

Tax

In November 2017, the European Commission (EC) gave formal notice of a preliminary view it had reached that the Group Financing Exemption, included in the UK’s Controlled Foreign Company rules, is in breach of the EU’s State Aid rules. The EC will conduct its detailed investigation during 2018, with a final decision expected later in the year, or even in 2019. Should the EC conclude that the State Aid rules are breached, the UK can appeal before the General Court (and possibly the Court of Justice thereafter). The Group and its advisors consider that it is unlikely that a finding of State Aid will ultimately be upheld.

Other

In limited cases, the Group may provide performance guarantees to third-party hotel owners to secure management contracts. At 31 December 2017, the amount provided in the Financial Statements was $6m (2016: $5m) and the maximum unprovided exposure under such guarantees was $31m (2016: $14m).

At 31 December 2017, the Group had outstanding letters of credit of $35m (2016: $37m) mainly relating to self insurance programmes.

The Group may guarantee bank loans made to facilitate third-party ownership of hotels under IHG management or franchise contracts. At 31 December 2017, there were guarantees of $54m in place (2016: $33m).

From time to time, the Group is subject to legal proceedings the ultimate outcome of each being always subject to many uncertainties inherent in litigation. In particular, the Group is currently subject to the claims listed under ‘Legal proceedings’ on page 172. The Group has also given warranties in respect of the disposal of certain of its former subsidiaries. It is the view of the Directors that, other than to the extent that liabilities have been provided for in these Financial Statements, it is not possible to quantify any loss to which these proceedings or claims under these warranties may give rise, however, as at the date of reporting, the Group does not believe that the outcome of these matters will have a material effect on the Group’s financial position.

At 31 December 2017, the Group had no other contingent liabilities (2016: $nil).

System Fund

32. System Fund

The Group operates a System Fund (the Fund) to collect and administer assessments and contributions from hotel owners (other than for Kimpton and InterContinental hotels) for specific use in marketing, the IHG Rewards Club loyalty programme and the Guest Reservation System. The Fund and loyalty programme are accounted for in accordance with the accounting policies set out on page 100 of the Financial Statements.

Following the announcement on 14 April 2015 of the introduction of an expiration policy for points earned under the loyalty programme, the Group released $156m from the programme’s future redemption liability in 2015. The amount released was based on the advice of an external actuary using statistical models to estimate the impact of the programme change on members’ behaviour. The liability release resulted in a corresponding increase in the System Fund surplus which was also recorded in the Group statement of financial position.

The following information is relevant to the operation of the Fund:

	2017 $m			2016 $m		2015  $m

The payroll costs above relate to 5,555 (2016: 5,434, 2015: 5,416) employees whose costs are borne by the Fund.

The following liabilities relating to the Fund are included in the Group statement of financial position:

	2017 $m		2016 $m		2015 $m

^a  The System Fund surplus is included in Trade and other payables.

^b  Comprising current liabilities of $343m and non-current liabilities of $417m.

The net change in the loyalty programme liability and Fund surplus contributed an inflow of $8m (2016: $65m, 2015: $42m) to the Group’s cash flow from operations.

Text block1 [abstract]

Basis of preparation

Basis of preparation

The Consolidated Financial Statements of IHG have been prepared on a going concern basis and under the historical cost convention, except for available-for-sale equity securities and derivatives which are measured at fair value. The Consolidated Financial Statements have been prepared in accordance with International Financial Reporting Standards (IFRSs) as issued by the IASB and in accordance with IFRS as adopted by the European Union (EU) and as applied in accordance with the provisions of the Companies Act 2006. IFRS as adopted by the EU differs in certain respects from IFRS as issued by the IASB. However, the differences have no impact on the Consolidated Financial Statements for the years presented.

Description of initial application of Standards or Interpretations

With effect from 1 January 2017, the Group has adopted:

• ‘Amendments to IAS 7 Statement of Cash Flows: Disclosure Initiative’, which requires disclosure of changes in liabilities arising from financing activities, including both changes arising from cash flows and non-cash changes, such as foreign exchange adjustments. This new disclosure is provided in note 20 to the Group Financial Statements.

• ‘Amendments to IAS 12 Income Taxes: Recognition of Deferred Tax Assets for Unrealised Losses’, which clarifies that an entity needs to consider whether tax law restricts the sources of taxable profits against which it may make deductions on the reversal of deductible temporary differences related to unrealised losses. The amendments also provide guidance on how an entity should determine future taxable profits and explain the circumstances in which taxable profit may include the recovery of some assets for more than their carrying amount. Application of these amendments has had no impact on the Group’s Financial Statements.

• Amendments to existing standards arising from the Annual Improvements to IFRSs 2014-2016 cycle. These amendments have not impacted the Group’s Financial Statements.

Presentational currency

Presentational currency

The Consolidated Financial Statements are presented in millions of US dollars reflecting the profile of the Group’s revenue and operating profit which are primarily generated in US dollars or US dollar-linked currencies.

In the Consolidated Financial Statements, equity share capital, the capital redemption reserve and shares held by employee share trusts are translated into US dollars at the rates of exchange on the last day of the period; the resultant exchange differences are recorded in other reserves.

The functional currency of the Parent Company is sterling since this is a non-trading holding company located in the United Kingdom that has sterling denominated share capital and whose primary activity is the payment and receipt of sterling dividends and of interest on sterling denominated external borrowings and inter-company balances.

Basis of consolidation

Basis of consolidation

The Consolidated Financial Statements comprise the Financial Statements of the Parent Company and entities controlled by the Group. Control exists when the Group has:

• Power over an investee (i.e. existing rights that give it the current ability to direct the relevant activities of the investee);

• Exposure, or rights, to variable returns from its involvement with the investee; and

• The ability to use its power over the investee to affect its returns.

All intra-group balances and transactions are eliminated on consolidation.

The assets, liabilities and results of those businesses acquired or disposed of are consolidated for the period during which they were under the Group’s control.

Information about interests in structured entity

The Group operates a deferred compensation plan in the US which allows certain employees to make additional provision for retirement, through the deferral of salary with matching company contributions. Employees can draw down on the plan in certain limited circumstances during employment. The assets of the plan are held in a company-owned trust which is not consolidated as the relevant activity of the trust, being the investment of the funds in the trust, is directed by the participating employees of the plan and the company has no exposure to the gains and losses resulting from those investment decisions. The assets of the trust are held solely for the benefit of the participating employees and to pay plan expenses, other than in the case of a company insolvency in which case they can be claimed by the general creditors of the company. At 31 December 2017, the trust had assets with a fair value of $197m (2016: $161m).

Foreign currencies

Foreign currencies

Transactions in foreign currencies are translated to functional currency at the exchange rates ruling on the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are retranslated to the functional currency at the relevant rates of exchange ruling on the last day of the period. Foreign exchange differences arising on translation are recognised in the income statement except on foreign currency borrowings that provide a hedge against a net investment in a foreign operation. These are taken directly to the currency translation reserve until the disposal of the net investment, at which time they are recycled against the gain or loss on disposal.

The assets and liabilities of foreign operations, including goodwill, are translated into US dollars at the relevant rates of exchange ruling on the last day of the period. The revenues and expenses of foreign operations are translated into US dollars at average rates of exchange for the period. The exchange differences arising on retranslation are taken directly to the currency translation reserve. On disposal of a foreign operation, the cumulative amount recognised in the currency translation reserve relating to that particular foreign operation is recycled against the gain or loss on disposal.

Property, plant and equipment

Property, plant and equipment

Property, plant and equipment are stated at cost less depreciation and any impairment.

Repairs and maintenance costs are expensed as incurred.

Land is not depreciated. All other property, plant and equipment are depreciated to a residual value over their estimated useful lives, namely:

• Buildings – lesser of 50 years and unexpired term of lease; and

• Fixtures, fittings and equipment – three to 25 years.

All depreciation is charged on a straight-line basis. Residual value is re-assessed annually.

Property, plant and equipment are tested for impairment when events or changes in circumstances indicate that the carrying value may not be recoverable. Assets that do not generate independent cash flows are combined into cash-generating units. If carrying values exceed their estimated recoverable amount, the assets or cash-generating units are written down to the recoverable amount. Recoverable amount is the greater of fair value less costs of disposal and value in use. Value in use is assessed based on estimated future cash flows discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. Impairment losses, and any subsequent reversals, are recognised in the income statement.

On adoption of IFRS, the Group retained previous revaluations of property, plant and equipment which are included at deemed cost as permitted by IFRS 1 ‘First-time Adoption of International Financial Reporting Standards’.

Business combinations and goodwill

Business combinations and goodwill

On the acquisition of a business, identifiable assets and liabilities acquired are measured at their fair value. Contingent liabilities assumed are measured at fair value unless this cannot be measured reliably, in which case they are not recognised but are disclosed in the same manner as other contingent liabilities. The measurement of deferred tax assets and liabilities arising on acquisition is as described in the general principles detailed within the ‘Taxes’ accounting policy note on page 98 with the exception that no deferred tax is provided on taxable temporary differences in connection with the initial recognition of goodwill.

Goodwill is recorded at cost, being the difference between the fair value of the consideration and the fair value of net assets acquired. Following initial recognition, goodwill is measured at cost less any accumulated impairment losses and is not amortised.

Goodwill is tested for impairment at least annually by comparing carrying values of cash-generating units with their recoverable amounts. Impairment losses relating to goodwill cannot be subsequently reversed.

Transaction costs are expensed and are not included in the cost of acquisition.

Intangible assets

Intangible assets

Brands

Externally acquired brands are initially recorded at cost if separately acquired or fair value if acquired as part of a business combination, provided the brands are controlled through contractual or other legal rights, or are separable from the rest of the business, and the fair value can be reliably measured. Brands are amortised over their estimated useful lives (and tested for impairment if there are indicators of impairment) or tested for impairment at least annually if determined to have indefinite lives.

The costs of developing internally generated brands are expensed as incurred.

Management contracts

Management contracts acquired as part of a business combination are initially recorded at the fair value attributed to those contracts on acquisition.

When hotel assets are sold and a purchaser enters into a franchise or management contract with the Group, the Group capitalises as part of the gain or loss on disposal an estimate of the fair value of the contract entered into.

The value of management contracts is amortised on a straight-line basis over the life of the contract including any extension periods at IHG’s option up to a maximum of 50 years.

Software

Acquired and internally developed software are capitalised on the basis of the costs incurred to acquire and bring to use the specific software. Costs are generally amortised over estimated useful lives of three to five years on a straight-line basis.

Internally generated development costs are expensed unless forecast revenues exceed attributable forecast development costs, in which case they are capitalised and amortised over the estimated useful life of the asset.

Other intangible assets

Amounts paid to hotel owners to secure management contracts and franchise agreements are capitalised and amortised on a straight-line basis over their estimated useful lives, being the full contractual term, up to a maximum of 50 years.

Intangible assets are reviewed for impairment when events or changes in circumstances indicate that the carrying value may not be recoverable.

Associates and joint ventures

Associates and joint ventures

An associate is an entity over which the Group has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the entity, but is not control or joint control over those policies.

A joint venture exists when two or more parties have joint control over, and rights to the net assets of, the venture. Joint control is the contractually agreed sharing of control which only exists when decisions about the relevant activities require the unanimous consent of the parties sharing control.

Associates and joint ventures are accounted for using the equity method unless the associate or joint venture is classified as held for sale. Under the equity method, the Group’s investment is recorded at cost adjusted by the Group’s share of post-acquisition profits and losses and other movements in the investee’s reserves. When the Group’s share of losses exceeds its interest in an associate or joint venture, the Group’s carrying amount is reduced to $nil and recognition of further losses is discontinued except to the extent that the Group has incurred legal or constructive obligations or made payments on behalf of an associate or joint venture.

If there is objective evidence that an associate or joint venture is impaired, an impairment charge is recognised if the carrying amount of the investment exceeds its recoverable amount.

Upon loss of significant influence over an associate or joint control of a joint venture, any retained investment is measured at fair value with any difference to carrying value recognised in the income statement.

Financial assets

Financial assets

The Group classifies its financial assets into one of the two following categories: loans and receivables or available-for-sale financial assets. Management determines the classification of financial assets on initial recognition and they are subsequently held at amortised cost (loans and receivables) or fair value (available-for-sale financial assets). Interest on loans and receivables is calculated using the effective interest rate method and is recognised in the income statement as interest income. Changes in fair values of available-for-sale financial assets are recorded directly in equity within the unrealised gains and losses reserve. On disposal, the accumulated fair value adjustments recognised in equity are recycled to the income statement. Dividends from available-for-sale financial assets are recognised in the income statement as other operating income and expenses.

Impairment of financial assets

Financial assets are assessed for impairment at each period-end date. In the case of an equity investment classified as available-for-sale, a significant or prolonged decline in fair value below cost is evidence that the asset is impaired. If an available-for-sale financial asset is impaired, the difference between original cost and fair value is transferred from equity to the income statement to the extent of any cumulative loss recorded in equity, with any excess charged directly to the income statement. Subsequent impairment reversals relating to previously impaired equity instruments are recorded in equity.

Trade receivables

Trade receivables

Trade receivables are recorded at their original amount less provision for impairment. It is the Group’s policy to provide for 100% of the previous month’s aged receivables balances which are more than 180 days past due. Adjustments to the policy may be made due to specific or exceptional circumstances. The carrying amount of the receivable is reduced through the use of a provision account and movements in the provision are recognised in the income statement within cost of sales. When a previously provided trade receivable is uncollectable, it is written off against the provision.

Cash and cash equivalents

Cash and cash equivalents

Cash comprises cash in hand and demand deposits.

Cash equivalents are short-term highly liquid investments with an original maturity of three months or less that are readily convertible to known amounts of cash and subject to insignificant risk of changes in value.

In the statement of cash flows, cash and cash equivalents are shown net of short-term overdrafts which are repayable on demand and form an integral part of the Group’s cash management.

Assets held for sale

Assets held for sale

Assets and liabilities are classified as held for sale when their carrying amount will be recovered principally through a sale transaction rather than continuing use and a sale is highly probable and expected to complete within one year. For a sale to be highly probable, management need to be committed to a plan to sell the asset and the asset must be actively marketed for sale at a price that is reasonable in relation to its current fair value.

Assets designated as held for sale are held at the lower of carrying amount at designation and fair value less costs to sell.

Depreciation is not charged against property, plant and equipment classified as held for sale.

Offsetting of financial assets and financial liabilities

Offsetting of financial assets and financial liabilities

Financial assets and financial liabilities are offset and the net amount is reported in the Group statement of financial position if there is a currently enforceable legal right to offset the recognised amounts and there is an intention to settle on a net basis or to realise the assets and settle the liabilities simultaneously. To meet these criteria, the right of set-off must not be contingent on a future event and must be legally enforceable in all of the following circumstances: the normal course of business, the event of default and the event of insolvency or bankruptcy of the Group and all of the counterparties.

Bank and other borrowings

Bank and other borrowings

Bank and other borrowings are initially recognised at the fair value of the consideration received less directly attributable transaction costs. They are subsequently measured at amortised cost. Finance charges, including the transaction costs and any discount or premium on issue, are recognised in the income statement using the effective interest rate method.

Borrowings are classified as non-current when the repayment date is more than 12 months from the period-end date or where they are drawn on a facility with more than 12 months to expiry.

Derivative financial instruments and hedging

Derivative financial instruments and hedging

Derivatives are initially recognised and subsequently re-measured at fair value. The method of recognising the re-measurement depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged.

Changes in the fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income and the unrealised gains and losses reserve to the extent that the hedges are effective. When the hedged item is recognised, the cumulative gains and losses on the related hedging instrument are reclassified to the income statement.

Changes in the fair value of derivatives designated as net investment hedges are recorded in other comprehensive income and the currency translation reserve to the extent that the hedges are effective. The cumulative gains and losses remain in equity until a foreign operation is sold, at which point they are reclassified to the income statement.

Changes in the fair value of derivatives which have either not been designated as hedging instruments or relate to the ineffective portion of hedges are recognised immediately in the income statement.

Documentation outlining the measurement and effectiveness of any hedging arrangement is maintained throughout the life of the hedge relationship.

Interest arising from currency derivatives and interest rate swaps is recorded in either financial income or expenses over the term of the agreement, unless the accounting treatment for the hedging relationship requires the interest to be taken to reserves.

Self insurance

Self insurance

Liabilities in respect of self insured risks include projected settlements for known and incurred but not reported claims. Projected settlements are estimated based on historical trends and actuarial data.

Provisions

Provisions

Provisions are recognised when the Group has a present obligation as a result of a past event, it is probable that a payment will be made and a reliable estimate of the amount payable can be made. If the effect of the time value of money is material, the provision is discounted using a current pre-tax discount rate that reflects the risks specific to the liability.

An onerous contract provision is recognised when the unavoidable costs of meeting the obligations under a contract exceed the economic benefits expected to be received under it.

In respect of litigation, provision is made when management consider it probable that payment may occur even though the defence of the related claim may still be ongoing through the court process.

Taxes

Taxes

Current tax

Current income tax assets and liabilities for the current and prior periods are measured at the amount expected to be recovered from, or paid to, the tax authorities, including interest. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted at the end of the reporting period.

Deferred tax

Deferred tax

Deferred tax assets and liabilities are recognised in respect of temporary differences between the tax base and carrying value of assets and liabilities including accelerated capital allowances, unrelieved tax losses, unremitted profits from subsidiaries, gains rolled over into replacement assets, gains on previously revalued properties and other short-term temporary differences.

Judgement is used when assessing the extent to which deferred tax assets, particularly in respect of tax losses, should be recognised. Deferred tax assets are therefore recognised to the extent that it is regarded as probable that there will be sufficient and suitable taxable profits (including the future release of deferred tax liabilities) in the relevant legal entity or tax group against which such assets can be utilised in the future. For this purpose, forecasts of future taxable profits are considered by assessing the Group’s forecast revenue and profit models, taking into account future growth predictions and operating cost assumptions. Accordingly, changes in assumptions to the Group’s forecasts may have an impact on the amount of future taxable profits and therefore the period over which any deferred tax assets might be recovered.

Deferred tax is calculated at the tax rates that are expected to apply in the periods in which the asset or liability will be settled, based on rates enacted or substantively enacted at the end of the reporting period.

Where deferred tax assets and liabilities arise in the same entity or group of entities and there would be a legal right to offset the assets and liabilities were they to reverse, the assets and liabilities are also offset on the Group statement of financial position. Similarly, if there is no legal right to offset assets against liabilities, the assets and liabilities are not offset.

Retirement benefits

Retirement benefits

Defined contribution plans

Payments to defined contribution schemes are charged to the income statement as they fall due.

Defined benefit plans

Plan assets are measured at fair value and plan liabilities are measured on an actuarial basis, using the projected unit credit method and discounting at an interest rate equivalent to the current rate of return on a high-quality corporate bond of equivalent currency and term to the plan liabilities. The difference between the value of plan assets and liabilities at the period-end date is the amount of surplus or deficit recorded in the statement of financial position as an asset or liability. An asset is recognised when the employer has an unconditional right to use the surplus at some point during the life of the plan or on its wind-up.

The service cost of providing pension benefits to employees, together with the net interest expense or income for the year, is charged to the income statement within ‘administrative expenses’. Net interest is calculated by applying the discount rate to the net defined benefit asset or liability, after any asset restriction. Past service costs and gains, which are the change in the present value of the defined benefit obligation for employee service in prior periods resulting from plan amendments, are recognised immediately the plan amendment occurs. Settlement gains and losses, being the difference between the settlement cost and the present value of the defined benefit obligations being settled, are recognised when the settlement occurs.

Re-measurements comprise actuarial gains and losses, the return on plan assets (excluding amounts included in net interest) and changes in the amount of any asset restrictions. Actuarial gains and losses may result from: differences between the actuarial assumptions underlying the plan liabilities and actual experience during the year or changes in the actuarial assumptions used in the valuation of the plan liabilities. Re-measurement gains and losses, and taxation thereon, are recognised in other comprehensive income and are not reclassified to profit or loss in subsequent periods.

Actuarial valuations are carried out on a regular basis and are updated for material transactions and other material changes in circumstances (including changes in market prices and interest rates) up to the end of the reporting period.

Revenue recognition

Revenue recognition

Revenue arises from the sale of goods and provision of services where these activities give rise to economic benefits received and receivable by the Group on its own account and result in increases in equity.

Revenue is derived from the following sources: franchise fees; management fees; owned and leased properties and other revenues which are ancillary to the Group’s operations, including technology fee income.

Revenue is recorded (excluding VAT and similar taxes) net of discounts.

The following is a description of the composition of revenues of the Group.

Franchise fees

Received in connection with the licence of the Group’s brand names, usually under long-term contracts with the hotel owner. The Group charges franchise royalty fees as a percentage of hotel rooms revenue and recognises the fees as the hotel revenues occur.

Management fees

Earned from hotels managed by the Group, usually under long-term contracts with the hotel owner. Management fees include a base fee, generally a percentage of hotel revenue, which is recognised as the hotel revenues occur and an incentive fee, generally based on the hotel’s annual profitability or cash flows, which is recognised over time when it is considered probable that the related performance criteria will be met.

Owned and leased

Primarily derived from hotel operations, including the rental of rooms and food and beverage sales from owned and leased hotels operated under the Group’s brand names. Revenue is recognised when rooms are occupied and food and beverages are sold.

Franchise fees and management fees include liquidated damages received from the early termination of contracts.

Other revenues are recognised when earned in accordance with the terms of the contract.

Share-based payments

Share-based payments

The cost of equity-settled transactions with employees is measured by reference to fair value at the date at which the right to the shares is granted. Fair value is determined by an external valuer using option pricing models.

The cost of equity-settled transactions is recognised, together with a corresponding increase in equity, over the period in which any performance or service conditions are fulfilled, ending on the date on which the relevant employees become fully entitled to the award (vesting date).

The income statement charge for a period represents the movement in cumulative expense recognised at the beginning and end of that period. No expense is recognised for awards that do not ultimately vest, except for awards where vesting is conditional upon a market or non-vesting condition, which are treated as vesting irrespective of whether or not the market or non-vesting condition is satisfied, provided that all other performance and/or service conditions are satisfied.

Leases

Leases

Operating lease rentals are charged to the income statement on a straight-line basis over the term of the lease.

Assets held under finance leases, which transfer to the Group substantially all the risks and benefits incidental to ownership of the leased item, are capitalised at the inception of the lease, with a corresponding liability being recognised for the fair value of the leased asset or, if lower, the present value of the minimum lease payments. Lease payments are apportioned between the reduction of the lease liability and finance charges in the income statement so as to achieve a constant rate of interest on the remaining balance of the liability. Assets held under finance leases are depreciated over the shorter of the estimated useful life of the asset and the lease term.

Disposal of non-current assets

Disposal of non-current assets

The Group recognises sales proceeds and any related gain or loss on disposal on completion of the sales process. In determining whether the gain or loss should be recorded, the Group considers whether it:

• Has a continuing managerial involvement to the degree associated with asset ownership;

• Has transferred the significant risks and rewards associated with asset ownership; and

• Can reliably measure and will actually receive the proceeds.

Fair value measurement

Fair value measurement

The Group measures available-for-sale equity securities and derivatives at fair value on a recurring basis and other assets when impaired by reference to fair value less costs of disposal. Additionally, the fair value of other financial assets and liabilities require disclosure.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is measured by reference to the principal market for the asset or liability assuming that market participants act in their economic best interests.

The fair value of a non-financial asset assumes the asset is used in its highest and best use, either through continuing ownership or by selling it.

The Group uses valuation techniques that maximise the use of relevant observable inputs using the following valuation hierarchy:

Level 1:	quoted (unadjusted) prices in active markets for identical assets or liabilities.
Level 2:	other techniques for which all inputs which have a significant effect on the recorded fair value are observable, either directly or indirectly.
Level 3:	techniques which use inputs which have a significant effect on the recorded fair value that are not based on observable market data.

Further disclosures on the particular valuation techniques used by the Group are provided in note 23.

For impairment testing purposes and where significant assets (such as property) are valued by reference to fair value less costs of disposal, an external valuation will normally be obtained using professional valuers who have appropriate market knowledge, reputation and independence.

Exceptional items

Exceptional items

The Group discloses certain financial information both including and excluding exceptional items. The presentation of information excluding exceptional items allows a better understanding of the underlying trading performance of the Group and provides consistency with the Group’s internal management reporting. Exceptional items are identified by virtue of either their size or nature so as to facilitate comparison with prior periods and to assess underlying trends in the financial performance of the Group and its regional operating segments. Exceptional items can include, but are not restricted to, gains and losses on the disposal of assets, impairment charges and reversals and restructuring costs.

Critical accounting policies and the use of judgements, estimates and assumptions

Critical accounting policies and the use of judgements, estimates and assumptions

In determining and applying the Group’s accounting policies, management are required to make judgements, estimates and assumptions. An accounting policy is considered to be critical if its selection or application could materially affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the Financial Statements, and the reported amounts of revenues and expenses during the reporting period. Management consider accounting for the System Fund to be a critical judgement and that critical estimates and assumptions are used in impairment testing and for measuring the loyalty programme liability, as discussed in further detail below. Estimates and assumptions are evaluated by management using historical experience and other factors believed to be reasonable based on current circumstances. Actual results could differ under different policies, judgements, estimates and assumptions or due to unforeseen circumstances.

System Fund – in addition to management or franchise fees, hotels within the IHG System (other than for Kimpton and InterContinental hotels) pay cash assessments and contributions which are collected by IHG for specific use within the System Fund (the Fund). The Fund also receives proceeds from the sale of IHG Rewards Club points. IHG exerts significant influence over the operation of the Fund, however the Fund is managed for the benefit of hotels in the System with the objective of driving revenues for the hotels. The Fund is used to pay for marketing, the IHG Rewards Club loyalty programme and the Guest Reservation System. The Fund is planned to operate at breakeven with any short-term timing surplus or deficit carried in the Group statement of financial position within working capital.

As all Fund income is designated for specific purposes and does not result in a profit or loss for the Group, the revenue recognition criteria as outlined in the accounting policy above are not met and therefore the income and expenses of the Fund are not included in the Group income statement.

The assets and liabilities relating to the Fund are included in the appropriate headings in the Group statement of financial position as the related legal, but not beneficial, rights and obligations rest with the Group. These assets and liabilities include the IHG Rewards Club liability, short-term timing surpluses and deficits and any receivables and payables related to the Fund.

The cash flows relating to the Fund are reported within ‘cash flow from operations’ in the Group statement of cash flows due to the close interrelationship between the Fund and the trading operations of the Group.

LOGO Further information on the Fund is included in note 32.

Loyalty programme – the hotel loyalty programme, IHG Rewards Club, enables members to earn points, funded through hotel assessments, during each qualifying stay at an IHG branded hotel and redeem points at a later date for free accommodation or other benefits. The future redemption liability is calculated by multiplying the number of points expected to be redeemed before they expire by the redemption cost per point. On an annual basis the Group engages an external actuary who uses statistical formulae to assist in the estimate of the number of points that will never be redeemed (‘breakage’).

Following the introduction of a points expiration policy in 2015, breakage has become more judgemental due to there being limited historical data on the impact of such a change. Actuarial gains and losses on the future redemption liability are borne by the System Fund and any resulting changes in the liability would correspondingly adjust the amount of short-term timing surpluses and deficits held in the Group statement of financial position.

At 31 December 2017, the future redemption liability was $760m (2016: $685m). Based on the conditions existing at the balance sheet date, a one percentage point decrease in the breakage estimate would increase this liability by approximately $10m.

Impairment testing – intangible assets with definite useful lives, and property, plant and equipment are tested for impairment when events or circumstances indicate that their carrying value may not be recoverable. Goodwill and intangible assets with indefinite useful lives are subject to an impairment test on an annual basis or more frequently if there are indicators of impairment. Assets that do not generate independent cash flows are combined into cash-generating units. Associates and joint ventures are tested for impairment when there is objective evidence that they might be impaired.

The impairment testing of individual assets or cash-generating units requires an assessment of the recoverable amount of the asset or cash-generating unit. If the carrying value of the asset or cash-generating unit exceeds its estimated recoverable amount, the asset or cash-generating unit is written down to its recoverable amount. Recoverable amount is the greater of fair value less costs of disposal and value in use. Value in use is assessed based on estimated future cash flows discounted to their present value using a pre-tax discount rate that is based on the Group’s weighted average cost of capital adjusted to reflect the risks specific to the business model and territory of the cash-generating unit or asset being tested. The outcome of such an assessment is subjective, and the result sensitive to the assumed future cash flows to be generated by the cash-generating units or assets and discount rates applied in calculating the value in use.

At 31 December 2017, the Group had goodwill of $237m (2016: $232m) and brands of $193m (2016: $193m), both of which are subject to annual impairment testing. Information on the impairment tests performed is included in note 13.

At 31 December 2017, the Group also had property, plant and equipment, other intangible assets and investments in associates and joint ventures with a net book value of $425m, $1,037m and $141m (2016: $419m, $867m and $111m) respectively. In 2017, an impairment charge of $18m (2016: $16m) was recognised in relation to an associate investment as described in detail in note 14. In respect of those other assets requiring an impairment test and depending on how recoverable amount was assessed, a 10% reduction in fair value or estimated future cash flows would have resulted in a further impairment charge of $13m.

New standards issued but not effective

New standards issued but not effective

The new and amended accounting standards discussed below are those which are expected to be relevant to the Group Financial Statements.

IFRS 15 ‘Revenue from Contracts with Customers’

IFRS 15 introduces a new five-step approach to measuring and recognising revenue from contracts with customers and will be adopted by the Group with effect from 1 January 2018. Under IFRS 15, revenue is recognised at an amount that reflects the consideration to which an entity expects to be entitled in exchange for transferring goods or services to a customer. Management’s assessment of the impact of IFRS 15 is substantially complete and a summary of the main changes and impacts on IHG are as follows:

1. Employee cost reimbursements

Under IFRS 15, the provision of employees to managed hotels is not considered to be a service that is distinct from the general hotel management service. Reimbursements for the costs of IHG employees working in managed hotels will therefore be shown as revenue with an equal matching cost, with no profit impact. Under current accounting, no revenue or matching cost is recognised.

2. Initial franchise and re-licensing fees

Under current accounting, application and re-licensing fees are recognised as revenue when billed as the monies received are not refundable and IHG has no further obligations to satisfy. Under IFRS 15, there is a requirement to consider whether the payment of these fees transfers a good or service to the customer that is distinct from the promise to provide franchise services. As this is not the case, IFRS 15 requires initial franchise and re-licensing fees to be recognised as franchise services are provided, over the life of the related contract. The spreading of these fees will result in an initial reduction to revenue and operating profit, and the recognition of deferred revenue on the balance sheet, reflecting the profile of increased amounts received in recent years.

3. Contract acquisition costs

Contract acquisition costs related to securing management and franchise contracts are currently charged to the income statement as incurred. Under IFRS 15, certain costs qualify to be capitalised as the cost of obtaining a contract and are amortised over the initial term of the related contract. This change results in an increase to operating profit and the capitalisation of contract costs on the balance sheet.

4. Amounts paid to hotel owners to secure management contracts and franchise agreements (‘Key money’)

Under current accounting, key money payments are capitalised as intangible assets and amortised over the life of the related contracts. Under IFRS 15, these payments are treated as consideration payable to a customer and therefore recognised as a deduction to revenue over the contract term. This change will result in a reduction to revenue, no change to operating profit, and the reclassification of key money on the balance sheet from intangible assets to contract assets.

5. Owned hotel disposals subject to a management contract

Under current accounting, when hotels are sold and the Group retains management of the hotel, the consideration recognised includes both the cash received and the fair value of the management contract which is capitalised as an intangible asset and subsequently amortised to the income statement. This accounting is governed by the ‘exchange of assets’ criteria included in IAS 16 ‘Property, Plant and Equipment’ and IAS 38 ‘Intangible Assets’. IFRS 15 specifically includes property sales in its scope and results in the sales consideration being recorded at the fair value of the encumbered hotel, which generally will be equivalent to the cash received. This change will result in the derecognition of historic intangible asset balances and a lower amortisation charge in the income statement.

6. System Fund revenues and expenses

The Group operates a System Fund (the Fund) to collect and administer cash assessments from hotel owners for the specific purpose of use in marketing, the guest reservation systems and hotel loyalty programme. The Fund also receives proceeds from the sale of loyalty points under third-party co-branding arrangements. The Fund is planned to break even and is managed for the benefit of hotels in the System with the objective of driving revenues for the hotels. Under current accounting, these receipts and expenses are not recorded in the Group income statement as set out on page 100.

Under IFRS 15, an entity is regarded as a principal if it controls a service prior to transfer to the customer. As marketing and reservations expenses primarily comprise payroll and marketing costs incurred under contracts entered into by the Group, management have determined that the Group controls these services. Fund revenues and expenses will therefore be recognised on a gross basis in the Group income statement. Assessment fees from hotel owners are generally levied as a percentage of hotel revenues and will be recognised as those hotel revenues occur.

In respect of the loyalty programme, the Group has determined that the related performance obligation is not satisfied in full until the member has redeemed the points at a participating hotel. Accordingly, revenue related to loyalty points earned by members or sold under co-brandingarrangements will be deferred in an amount that reflects the stand-alone selling price of the future benefit to the member. As materially all of the points will be redeemed at IHG managed or franchised hotels owned by third parties, IHG is deemed to be acting as agent on redemption and will therefore recognise the related revenue net of the cost of reimbursing the hotel that is providing the hotel stay. The deferred revenue balance under IFRS 15 will be significantly higher than the points redemption cost liability that is recognised under current accounting resulting in an increase in the Group’s net liabilities.

Management has also determined that in addition to the performance obligation for the redemption of points, co-branding arrangements contain other performance obligations including marketing services and the right to access the loyalty programme. Revenue attributable to the stand-alone selling price of these additional services is recognised over the term of the co-branding arrangement.

Certain travel agency commission revenues within the Fund will continue to be recognised on a net basis, where it has been determined that IHG acts as agent under IFRS 15.

7. System Fund surplus or deficit

Under current accounting, the Fund surplus or deficit is carried forward on the Group statement of financial position as set out on page 100. Under IFRS 15, the Fund surplus or deficit will be recognised in the Group income statement. Both the current accounting treatment and the change on applying IFRS 15, and the equivalent US GAAP standard, are consistent with current and expected future practice across the hotel industry. The Fund surplus of $158m at 31 December 2017 will be derecognised resulting in a reduction in the Group’s net liabilities.

The changes detailed in 6 and 7 above will result in an increase in recorded revenue and reduction in operating profit in 2017.

8. Presentation and disclosure

The presentation and disclosure requirements of IFRS 15 represent a significant change from current practice and will increase the volume of disclosures required in the notes to the financial statements.

9. Quantification of impacts

The Group will apply the full retrospective approach when transitioning to the new standard which will result in restated comparatives on the basis that IFRS 15 had always applied.

The estimated impacts of adjustments 1. to 5. on the 2017 results are as follows:

Impact	Group revenue $m			Group operating profit $m			Group net liabilities $m
1. Employee cost reimbursements		1,103			—			—
2. Initial franchise and re-licensing fees		(14	)		(14	)		(111	)
3. Contract acquisition costs		—			5			43
4. Key money		(17	)		—			—
5. Derecognition of management contracts		—			8			(192	)
Other		2			—			1
		1,074			(1	)		(259	)

The impact of deferring revenue in relation to the loyalty programme and recognising System Fund revenues and expenses in the Group income statement (items 6. and 7.) is expected to increase Group revenue by an additional $1.2bn. The impact on Group operating profit and Group net liabilities is still being assessed. The Group has an agreement with the IHG Owners Association to spend Fund income for the benefit of hotels in the IHG System such that the Group does not make a profit or loss from operating the Fund over the medium term.

IFRS 9 ‘Financial Instruments’

IFRS 9, which will be adopted by the Group with effect from 1 January 2018, introduces new requirements for classification and measurement of financial assets and financial liabilities, impairment and hedge accounting. Management’s assessment of the impact of IFRS 9 is substantially complete and a summary of the changes and impacts on IHG are as follows:

1. Financial assets at fair value through other comprehensive income

The Group holds equity investments which it currently classifies as available-for-sale financial assets. Changes in fair value are accumulated in equity and on disposal are recycled through the income statement. Under IFRS 9, these assets will be recorded at fair value through other comprehensive income with no recycling to the income statement.

IFRS 9 will not be applied to assets derecognised prior to 1 January 2018 and therefore there will be no change to the gain of $73m recognised on disposal of an available-for-sale equity investment in 2017 (see note 5).

2. Trade receivables and loans issued to hotel owners to secure

management contracts and franchise agreements Trade receivables, trade deposits and loans issued to hotel owners to secure management contracts and franchise agreements are held to collect contractual cash flows and are expected to give rise to cash flows representing solely payments of principal and interest. Management have therefore concluded that they continue to meet the criteria for amortised cost measurement under IFRS 9.

3. Impairment

The Group will apply the three-stage expected credit loss model introduced by IFRS 9 in respect of trade deposits and loans issued to hotel owners to secure management contracts and franchise agreements. The expected credit loss model is based on the concepts of ’12-month expected credit losses’ or ‘lifetime expected credit losses’ depending on the performance of the underlying asset. Management’s current assessments do not indicate any material change in impairment provisions as a result of IFRS 9.

The Group will apply the simplified version of the expected credit loss model permitted by IFRS 9 in respect of trade receivables, which involves assessing lifetime expected credit losses on all balances. To estimate the required impairment provision, management has assessed historical collection rates by geographical region, incorporating adjustments for future expectations. No material impact on the financial statements is expected from application of the expected credit loss model to trade receivables.

4. Hedge accounting

Management have determined that all existing hedge relationships that are currently designated effective hedging relationships will continue to qualify for hedge accounting under IFRS 9. As IFRS 9 does not change the general principles of how an entity accounts for effective hedges, applying the hedging requirements of IFRS 9 will not impact the Group Financial Statements.

5. Financial liabilities

Management’s initial assessments indicate no impact on the Group’s accounting for financial liabilities as the rules on classification and measurement of financial liabilities remain largely unchanged compared with IAS 39.

Except for hedge accounting, retrospective application of IFRS 9 is required. The new rules for hedge accounting will be applied prospectively in line with the requirements of the new standard. The Group does not plan to restate prior periods as allowed by the transition provisions of IFRS 9.

IFRS 16 ‘Leases’

The Group will adopt IFRS 16 with effect from 1 January 2019. The standard eliminates the classification of leases as either operating or finance leases and introduces a single accounting model which is similar to the current accounting model for finance leases under IAS 17.

Lessees will be required to recognise on the balance sheet ‘right-of-use’ assets which represent the right to use underlying assets during the lease term and a lease liability representing the minimum lease payment for all leases. Depreciation of ‘right-of-use’ assets and interest on lease liabilities will be charged to the income statement, replacing the corresponding operating lease rentals.

The Group will take the elections available under IFRS 16 not to apply the lease accounting model to leases which are considered low value or which have a term of less than 12 months.

The Group currently plans to apply the full retrospective method of application. Management are currently quantifying the impact of adopting IFRS 16 which is expected to result in an increase in lease liabilities of $350m–$400m at 31 December 2017, and an immaterial impact on profit after tax.

Other

From 1 January 2018, the Group will apply Amendments to IFRS 2 ‘Classification and Measurement of Share-Based Payment Transactions’. The amendments address the effects of vesting conditions on the measurement of cash-settled share-based payment transactions; the classification of a share-based payment transaction with net settlement features for withholding tax obligations and accounting where a modification to the terms and conditions of a share-based payment transaction changes its classification from cash-settled to equity-settled. Adoption of this amendment is not expected to have a material impact on the financial statements.

From 1 January 2019, the Group will apply the amendments to:

• IAS 28 ‘Investments in Associates and Joint Ventures’ relating to long-term interests to which the equity method is not applied;

• IFRS 9 ‘Financial Instruments’ relating to prepayment features with negative compensation;

• IFRIC 23 ‘Uncertainty over Income Tax Treatments’; and

• Other existing standards arising from the Annual Improvements to IFRSs 2015–2017 cycle.

The amendments are not expected to have a material impact on the Group’s reported financial performance or position.

1. Exchange rates

The results of operations have been translated into US dollars at the average rates of exchange for the year. In the case of sterling, the translation rate is $1=£0.78 (2016: $1=£0.74, 2015: $1=£0.65). In the case of the euro, the translation rate is $1=€0.89 (2016: $1=€0.90, 2015: $1=€0.90).

Assets and liabilities have been translated into US dollars at the rates of exchange on the last day of the year. In the case of sterling, the translation rate is $1=£0.74 (2016: $1=£0.81, 2015: $1=£0.68). In the case of the euro, the translation rate is $1=€0.83 (2016: $1=€0.95, 2015: $1=€0.92).

Summary of Information by Reportable Segment

The management of the Group’s operations, excluding Central functions, is organised within four geographical regions:

• Americas;

• Europe;

• Asia, Middle East and Africa (AMEA); and

• Greater China.

These, together with Central functions, comprise the Group’s five reportable segments. No operating segments have been aggregated to form these reportable segments.

Central functions include costs of global functions including technology, sales and marketing, finance, human resources and corporate services; central revenue arises principally from technology fee income. Central liabilities include the loyalty programme liability and the cumulative System Fund surplus.

Each of the geographical regions is led by its own Chief Executive Officer and derives its revenues from either franchising, managing or owning hotels and additional segmental disclosures are provided accordingly.

Management monitors the operating results of the geographical regions and Central functions separately for the purpose of making decisions about resource allocation and performance assessment. Segmental performance is evaluated based on operating profit or loss and is measured consistently with operating profit or loss in the Consolidated Financial Statements, excluding exceptional items. Group financing activities and income taxes are managed on a group basis and are not allocated to reportable segments.

^a  Relates to the cost of integrating Kimpton into the operations of the Group, which has now been completed.

^b  In September 2017, the Group launched a comprehensive efficiency programme which will fund a series of new strategic initiatives to drive an acceleration in IHG’s future growth. The programme is centred around strengthening the Group’s organisational structure to redeploy resources to leverage scale in the highest opportunity markets and segments. The programme is expected to be completed in 2019. Included in the $36m cost are consultancy fees of $24m and severance costs of $8m. An additional $9m has been charged to the System Fund.

^c  Arose from changes to the Venezuelan exchange rate mechanisms and the adoption of the SIMADI exchange rate in 2015, this being the most accessible exchange rate open to the Group for converting its bolivar earnings into US dollars. The exceptional loss arose from the re-measurement of the Group’s bolivar assets and liabilities to the relevant exchange rate, being approximately $1=190VEF on adoption of SIMADI. Subsequent changes to the exchange rate mechanism have not resulted in material losses.

^d  Primarily legal costs related to development opportunities.

^e  In 2017, comprises a $7m (2016: $6m) deferred tax credit in respect of an associate investment impairment, a $6m (2016: $5m) deferred tax credit representing future tax relief on Kimpton integration costs, a $13m current tax credit in respect of reorganisation costs and a $28m current tax charge relating to the gain on disposal of Avendra (see note 15). In 2016, there was also a $1m credit in respect of other items. In 2015, comprised a charge of $56m relating to disposal of hotels, a credit of $21m in respect of the 2014 disposal of an 80.1% interest in InterContinental New York Barclay reflecting the judgement that state tax law changes would now apply to the deferred gain, and credits of $27m for current and deferred tax relief on other operating exceptional items of current and prior periods.

^f  Includes $108m relating to the impact of significant US tax reform that was enacted on 22 December 2017. This includes a current tax charge of $32m, relating predominantly to the Group’s estimated ‘transition tax’ liability on previously undistributed earnings of foreign subsidiaries of US entities, and a deferred tax credit of $140m, being principally the impact of the US federal tax rate reduction from 35% to 21% (effective 1 January 2018) on the Group’s US deferred tax liabilities, as well as the release of liabilities related to the Group’s undistributed post-acquisition earnings of subsidiaries that are no longer required as a result of the US transition tax. In addition, a deferred tax credit of $10m arises on the release of a contingency, previously charged as an exceptional item, which is no longer required due to statute of limitations expiry.

Description of changes in assumptions used for determining retirement benefit costs		Changes in assumptions used for determining retirement benefit costs and obligations may have a material impact on the income statement and the statement of financial position. The key assumptions are the pension increases, discount rate, the rate of inflation and the assumed mortality rate. The sensitivity analysis below is based on extrapolating reasonable changes in these assumptions, using year-end conditions and assuming no interdependency between the assumptions.
Expected company payments		$ 9.0
Actuarial assumption of expected rates of mortality [Member]
Disclosure of defined benefit plans [line items]
Mortality - per annum long term trend		1.25%
Mortality - male pensioners age rated down		8 months 12 days
Mortality - male non-pensioners age rated down		6 months
Mortality - female pensioners age rated down		2 years 3 months 19 days
Mortality - female non-pensioners age rated down		2 years 7 months 6 days
Description of mortality assumptions		Mortality is the most significant demographic assumption. [The current assumptions for the UK are based on the S2PA ‘light’ year of birth tables with projected mortality improvements using the CMI_2015 model and a 1.25% per annum long-term trend with age rated down by 0.7 and 2.3 years for pensioners and 0.5 and 2.6 years for non-pensioners, male and female respectively. In the US, the current assumptions are based on the RP-2014 Employee/Healthy Annuitant Generationally Projected with Scale MP-2016 mortality tables.

Description of retirement benefit plan		The Group also maintains the following US-based defined benefit plans: the funded Inter-Continental Hotels Pension Plan (the Plan), unfunded Inter-Continental Hotels Non-qualified Pension Plans and unfunded Inter-Continental Hotels Corporation Postretirement Medical, Dental, Vision and Death Benefit Plan. All plans are closed to new members. In respect of the Plan, an Investment Committee has responsibility for the oversight and management of the plan’s assets, which are held in a separate trust. The Committee comprises senior company employees and is assisted by professional advisers as and when required.
Explanation of changes in description of retirement benefit plan		During 2015, the Group made a lump sum cash-out offer to the terminated vested members of the Inter-Continental Hotels Pension Plan. Members accepting the offer received lump sum cash payments totalling $11m on 1 November 2015.During 2016, the Group made a funding contribution of $32m to the Plan which has enabled it to achieve full funding. The assets of the Plan have subsequently been invested 100% in liability-matching assets.

Description of retirement benefit plan		Since 6 August 2014, UK retirement and death in service benefits are provided for eligible employees by the IHG UK Defined Contribution Pension Plan. Members, including those who have been auto-enrolled since 1 September 2013, are provided with defined contribution arrangements under this plan; benefits are based on each individual member’s personal account. The plan is HM Revenue & Customs registered and governed by an independent trustee, assisted by professional advisers as and when required. The overall operation of the plan is subject to the oversight of The Pensions Regulator. Residual defined benefit obligations remain in respect of additional benefits provided to members of an unfunded pension arrangement who were affected by lifetime or annual allowances under the former defined benefit arrangements. Accrual under this arrangement ceased with effect from 1 July 2013 and a cash-out offer in 2014 resulted in the extinguishment of approximately 70% of the unfunded pension obligations. The Company meets the benefit payment obligations of the remaining members as they fall due. A charge over certain ring-fenced bank accounts totalling £31m at 31 December 2016 (see note 15) is currently held as security on behalf of the remaining members.
Explanation of changes in description of retirement benefit plan		The former defined benefit plan, the InterContinental Hotels UK Pension Plan, was wound up on 21 July 2015 following the completion of the buy-out and transfer of the defined benefit obligations to Rothesay Life on 31 October 2014.
