Accounting Policies	Accounting Policies (including key accounting estimates and assumptions) This document constitutes both the Annual Report and the Financial Statements in accordance with the Irish and UK requirements, and the Annual Report on Form 20-F Basis of Preparation The Consolidated Financial Statements of CRH plc have been prepared in accordance with I n CRH plc, the Parent Company, is a publicly traded limited company incorporated and domiciled in the Republic of Ireland. The Consolidated Financial Statements, which are presented in euro millions, have been prepared under the historical cost convention as modified by the measurement at fair value of share-based payments, retirement benefit obligations and certain financial assets and liabilities including derivative financial instruments. The accounting policies set out below have been applied consistently by all of the Group’s subsidiaries, joint ventures and associates to all periods presented in the Consolidated Financial Statements. In accordance with Section 304 of the Companies Act 2014, the Company is availing of the exemption from presenting its individual profit and loss account to the Annual General Meeting and from filing it with the Registrar of Companies. Adoption of IFRS and International Financial Reporting Interpretations Committee (IFRIC) interpretations The following new standards, interpretations and standard amendments became effective for the Group as of 1 January 2019: • IFRS 16 Leases • IFRIC 23 Uncertainty over Income Tax Treatments • Amendments to IFRS 9 Financial Instruments • Amendments to IAS 19 Employee Benefits • Amendments to IAS 28 Investments in Associates and Joint Ventures • Annual Improvements 2015 – 2017 Cycle The new standards, interpretations and standard amendments did not result in a material impact on the Group’s results, with the exception of IFRS 16 which is detailed below. IFRS 16 Leases IFRS 16 replaces IAS 17 Leases low-value non-lease right-of-use Provisions, Contingent Liabilities and Contingent Assets The adoption of IFRS 16 had a material impact on the Group’s Consolidated Financial Statements and certain key financial metrics, which is quantified and further explained in the table overleaf. Primary statement line item / financial metric As at 1 January 2019 € Consolidated Balance Sheet Property, plant and equipment (i) (ii) +1,939 Lease liabilities; net debt (i) (ii) +1,954 For the year ended € Consolidated Income Statement Depreciation (i) +334 Finance costs +69 EPS (i) (iii) -3c Consolidated Statement of Cash Flows Net cash flow from operating activities +317 Net cash flow from financing activities -317 (i) The operating profit and depreciation impact of IFRS 16 on discontinued operations included above are + € € right-of-use € (ii) The impact of the adoption of IFRS 16 on property, plant and equipment and net debt is net of existing finance leases ( € right-of-use (iii) The impact of the adoption of IFRS 16 on operating profit for the year ended 31 December 2019 is € Income Statement Cost of sales and operating costs (excluding depreciation) have decreased, as the Group previously recognised operating lease expenses in either cost of sales or operating costs (depending on the nature of the relevant operations and of the lease). The Group’s operating lease expense for the year ended 31 December 2018 from continuing operations was € € Depreciation and finance costs have increased due to the capitalisation of a right-of-use Balance Sheet The Group has identified the minimum lease payments outstanding (including payments for renewal options which are reasonably certain to be exercised) and has applied the appropriate discount rate to calculate the present value of the lease liability and right-of-use A reconciliation of the operating lease commitment previously reported under IAS 17 to the discounted lease liability as at 1 January 2019 under IFRS 16 is as follows: As at 1 January 2019 € Operating lease commitment under IAS 17 1,911 Lease extensions beyond break date 632 Leases that are cancellable at any time 35 Existing IAS 17 finance leases (i) 23 Other lease payments not included in discounted lease liability under IFRS 16 (ii) (108) Undiscounted lease liability under IFRS 16 2,493 Less impact of discounting (516) Discounted lease liability under IFRS 16 1,977 (i) Existing IAS 17 finance leases are presented at discounted amounts as the impact of discounting on these leases is not considered material. (ii) Other lease payments not included in the discounted lease liability under IFRS 16 include payments related to short-term and low-value IFRS and IFRIC interpretations being adopted in subsequent years IFRS 17 Insurance Contracts In May 2017, the IASB issued IFRS 17. It is expected to be effective for reporting periods beginning on or after 1 January 2022, with presentation of comparative figures required. The Group is currently evaluating the impact of this standard on future periods. IFRS 3 Business Combinations In October 2018, the IASB issued amendments to IFRS 3, regarding the definition of a business. The amendments clarify that the process required to meet the definition of a business (together with inputs to create outputs) must be substantive; and, that the inputs and process must together significantly contribute to creating outputs. The definition of outputs has been narrowed to focus on goods and services provided to customers and other income from ordinary activities. In addition, the amendments indicate that an acquisition of primarily a single asset or group of similar assets is unlikely to meet the definition of a business. The amendments will be applied prospectively for business combinations and asset acquisitions occurring on or after 1 January 2020. The Group is finalising its review of the impact of this amendment, but does not expect the clarification to have a material impact on the value of acquisitions or additions to property, plant and equipment. Disclosure Initiative – Definition of Material (Amendments to IAS 1 and IAS 8) In October 2018, the IASB issued Definition of Material (Amendments to IAS 1 Presentation of Financial Statements Accounting Policies, Changes in Accounting Estimates and Errors Interest Rate Benchmark Reform – Amendments to IFRS 9, IAS 39 and IFRS 7 In September 2019, the IASB issued amendments to IFRS 9, IAS 39 Financial Instruments: Recognition and Measurement Financial Instruments: Disclosures The amendments provide mandatory temporary reliefs which enable hedge accounting to continue during the period of uncertainty before the replacement of an existing interest rate benchmark with an alternative nearly risk-free interest rate (an RFR). To the extent that a hedging instrument is altered so that its cash flows are based on an RFR, but the hedged item is still based on IBOR (or vice versa), there is no relief from measuring and recording any ineffectiveness that arises due to differences in their changes in fair value. The amendments are effective from 1 January 2020 and must be applied retrospectively. However, any hedge relationships that have previously been de-designated cannot be reinstated upon application, nor can any hedge relationships be designated with the benefit of hindsight. The Group is currently evaluating the impact of this amendment, but does not expect the amendment to have a material impact. There are no other IFRS or IFRIC interpretations that are effective subsequent to the CRH 2019 financial year-end Key Accounting Policies which involve Estimates, Assumptions and Judgements The preparation of the Consolidated Financial Statements in accordance with IFRS requires management to make certain estimates, assumptions and judgements that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Management believes that the estimates, assumptions and judgements upon which it relies are reasonable based on the information available to it at the time that those estimates, assumptions and judgements are made. In some cases, the accounting treatment of a particular transaction is specifically dictated by IFRS and does not require management’s judgement in its application. Management considers that their use of estimates, assumptions and judgements in the application of the Group’s accounting policies are inter-related and therefore discuss them together below. Estimates and underlying assumptions are reviewed on an ongoing basis. Changes in accounting estimates may be necessary if there are changes in the circumstances or experiences on which the estimate was based or as a result of new information. The critical accounting policies which involve significant estimates, assumptions or judgements, the actual outcome of which could have a material impact on the Group’s results and financial position outlined below, are as follows: Impairment of goodwill – Note 16 In the year in which a business combination is effected and where some or all of the goodwill allocated to a particular cash-generating unit arose in respect of that combination, the cash-generating unit is tested for impairment prior to the end of the relevant annual period. Goodwill is subject to impairment testing on an annual basis and at any time during the year if an indicator of impairment is considered to exist. Where the carrying value exceeds the estimated recoverable amount (being the greater of fair value less costs of disposal and value-in-use), value-in-use, pre-tax Goodwill relating to associates and joint ventures is included in the carrying amount of the investment and is neither amortised nor individually tested for impairment. Where indicators of impairment of an investment arise in accordance with the requirements of IFRS 9, the carrying amount is tested for impairment by comparing its recoverable amount with its carrying amount. The impairment testing process requires management to make significant judgements and estimates regarding the future cash flows expected to be generated by cash-generating units to which goodwill has been allocated. Future cash flows relating to the eventual disposal of these cash-generating units and other factors may also be relevant to determine the fair value of goodwill. Management periodically evaluates and updates the estimates based on the conditions which influence these variables. A detailed discussion of the impairment methodology applied and key assumptions used by the Group in the context of goodwill is provided in note 16 to the Consolidated Financial Statements. The assumptions and conditions for determining impairments of goodwill reflect management’s best assumptions and estimates, but these items involve inherent uncertainties described above, many of which are not under management’s control. As a result, the accounting for such items could result in different estimates or amounts if management used different assumptions or if different conditions occur in future accounting periods. Retirement benefit obligations – Note 30 Costs arising in respect of the Group’s defined contribution pension schemes are charged to the Consolidated Income Statement in the period in which they are incurred. The Group has no legal or constructive obligation to pay further contributions in the event that the fund does not hold sufficient assets to meet its benefit commitments. The liabilities and costs associated with the Group’s defined benefit pension schemes (both funded and unfunded) are assessed either on the basis of the attained age, the projected unit credit, the current unit credit or the aggregate cost methods by professionally qualified actuaries and are arrived at using actuarial assumptions based on market expectations at the balance sheet date. The discount rates employed in determining the present value of the schemes’ liabilities are determined by reference to market yields at the balance sheet date on high-quality corporate bonds of a currency and term consistent with the currency and term of the associated post-employment benefit obligations. The net surplus or deficit arising on the Group’s defined benefit pension schemes, together with the liabilities associated with the unfunded schemes, are shown either within non-current non-current The defined benefit pension asset or liability in the Consolidated Balance Sheet comprises the total for each plan of the present value of the defined benefit obligation less the fair value of plan assets out of which the obligations are to be settled directly. Plan assets are assets that are held by a long-term employee benefit fund or qualifying insurance policies. Fair value is based on market price information and, in the case of published quoted securities; it is the published bid price. The value of any defined benefit asset is limited to the present value of any economic benefits available in the form of refunds from the plan and reductions in the future contributions to the plan. The Group’s obligation in respect of post-employment healthcare and life assurance benefits represents the amount of future benefit that employees have earned in return for service in the current and prior periods. The obligation is computed on the basis of the projected unit credit method and is discounted to present value using a discount rate equating to the market yield at the balance sheet date on high-quality corporate bonds of a currency and term consistent with the currency and estimated term of the post-employment obligations. Assumptions The assumptions underlying the actuarial valuations (including discount rates, rates of increase in future compensation levels, mortality rates and healthcare cost trends), from which the amounts recognised in the Consolidated Financial Statements are determined, are updated annually based on current economic conditions and for any relevant changes to the terms and conditions of the pension and post-retirement plans. These assumptions can be affected by (i) for the discount rate, changes in the rates of return on high-quality corporate bonds; (ii) for future compensation levels, future labour market conditions and (iii) for healthcare cost trend rates, the rate of medical cost inflation in the relevant regions. The weighted average actuarial assumptions used and sensitivity analysis in relation to the significant assumptions employed in the determination of pension and other post-retirement liabilities are contained in note 30 to the Consolidated Financial Statements. Whilst management believes that the assumptions used are appropriate, differences in actual experience or changes in assumptions may affect the obligations and expenses recognised in future accounting periods. The assets and liabilities of defined benefit pension schemes may exhibit significant period-on-period Provisions for liabilities – Note 28 A provision is recognised when the Group has a present obligation (either legal or constructive) as a result of a past event, it is probable that a transfer of economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. Where the Group anticipates that a provision will be reimbursed, the reimbursement is recognised as a separate asset only when it is virtually certain that the reimbursement will arise. The expense relating to any provision is presented in the Consolidated Income Statement net of any reimbursement. Provisions are measured at the present value of the expenditures expected to be required to settle the obligation. The increase in the provision due to the passage of time is recognised as an interest expense. Contingent liabilities arising on business combinations are recognised as provisions if the contingent liability can be reliably measured at its acquisition date fair value. Provisions are not recognised for future operating losses. Management is not aware of any potential changes to key assumptions that have a significant risk of causing a material adjustment to the carrying value of provisions within the next financial year; however due to the nature of some of our provisions, estimates may depend on the outcome of future events and need to be revised as circumstances change in future accounting periods. Refer to note 28 for the expected timing of outflows by provisions category. Environmental and remediation provisions The measurement of environmental and remediation provisions is based on an evaluation of currently available facts with respect to each individual site and considers factors such as existing technology, currently enacted laws and regulations and prior experience in remediation of sites. Inherent uncertainties exist in such evaluations primarily due to unknown conditions, changing governmental regulations and legal standards regarding liability, the protracted length of the clean-up Legal contingencies The status of each significant claim and legal proceeding in which the Group is involved is reviewed by management on a periodic basis and the Group’s potential financial exposure is assessed. If the potential loss from any claim or legal proceeding is considered probable, and the amount can be reliably estimated, a liability is recognised for the estimated loss. Because of the uncertainties inherent in such matters, the related provisions are based on the best information available at the time; the issues taken into account by management and factored into the assessment of legal contingencies include, as applicable, the status of settlement negotiations, interpretations of contractual obligations, prior experience with similar contingencies/claims, the availability of insurance to protect against the downside exposure and advice obtained from legal counsel and other third parties. As additional information becomes available on pending claims, the potential liability is reassessed and revisions are made to the amounts accrued where appropriate. Such revisions in the judgements and estimates of the potential liabilities could have an impact on the results of operations and financial position of the Group in future accounting periods. Insurance provisions Insurance provisions are subject to actuarial valuation and are based on actuarial triangulations which are extrapolated from historical claims experience. These provisions include claims which are classified as “incurred but not reported”, the status of which are reviewed periodically by management, in conjunction with appropriately qualified advisors. Changes in actuarial methodologies and assumptions, along with the receipt of new information, could have an impact on the financial position of the Group through recognition of additional, or release of, provisions in future accounting periods. Taxation – current and deferred – Notes 12 and 29 Current tax represents the expected tax payable (or recoverable) on the taxable profit for the year using tax rates enacted for the period. Any interest or penalties arising are included within current tax. Where items are accounted for outside of profit or loss, the related income tax is recognised either in other comprehensive income or directly in equity as appropriate. Deferred tax is recognised using the liability method on temporary differences arising at the balance sheet date between the tax bases of assets and liabilities and their carrying amounts in the Consolidated Financial Statements. However, deferred tax liabilities are not recognised if they arise from the initial recognition of goodwill. In addition, deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that, at the time of the transaction, affects neither accounting nor taxable profit or loss. For the most part, no provision has been made for temporary differences applicable to investments in subsidiaries and joint ventures as the Group is in a position to control the timing of reversal of the temporary differences and it is probable that the temporary differences will not reverse in the foreseeable future. However, a temporary difference has been recognised to the extent that specific assets have been identified for sale or where there is a specific intention to unwind the temporary difference in the foreseeable future. Due to the absence of control in the context of associates (significant influence only), deferred tax liabilities are recognised where appropriate in respect of CRH’s investments in these entities on the basis that the exercise of significant influence would not necessarily prevent earnings being remitted by other shareholders in the undertaking. Deferred tax is determined using tax rates (and laws) that have been enacted or substantively enacted by the balance sheet date and are expected to apply when the related deferred income tax asset is realised or the deferred income tax liability is settled. Deferred tax assets and liabilities are not subject to discounting. Deferred tax assets are recognised in respect of all deductible temporary differences, carry-forward of unused tax credits and unused tax losses to the extent that it is probable that taxable profits will be available against which the temporary differences can be utilised. The carrying amounts of deferred tax assets are subject to review at each balance sheet date and are reduced to the extent that future taxable profits are considered to be inadequate to allow all or part of any deferred tax asset to be utilised. The Group’s income tax charge is based on reported profit and enacted statutory tax rates, which reflect various allowances and reliefs and tax planning opportunities available to the Group in the multiple tax jurisdictions in which it operates. The determination of the Group’s provision for income tax requires certain judgements and estimates in relation to matters where the ultimate tax outcome may not be certain. The recognition or non-recognition year-end, Other Significant Accounting Policies Basis of consolidation The Consolidated Financial Statements include the financial statements of the Parent Company and all subsidiaries, joint ventures and associates, drawn up to 31 December each year. The financial year-ends of the Group’s subsidiaries, joint ventures and associates are co-terminous. Subsidiaries Subsidiaries are all entities over which the Group has control. The Group controls an entity when the Group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control ceases. A change in the ownership interest of a subsidiary without a change in control is accounted for as an equity transaction. When the Group holds less than the majority of voting rights, other facts and circumstances including contractual arrangements that give the Group power over the investee may result in the Group controlling the investee. The Group reassesses whether it controls an investee if, and when, facts and circumstances indicate that there are changes to the elements evidencing control. Non-controlling non-controlling non-controlling non-controlling Investments in associates and joint ventures – Notes 11 and 17 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 an entity, but is not control or joint control over those policies. A joint venture is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the joint venture. Joint control is the contractually agreed sharing of control of the arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control. The Group’s investments in its associates and joint ventures are accounted for using the equity method from the date significant influence/joint control is deemed to arise until the date on which significant influence/joint control ceases to exist or when the interest becomes classified as an asset held for sale. The Consolidated Income Statement reflects the Group’s share of profit after tax of the related associates and joint ventures. Investments in associates and joint ventures are carried in the Consolidated Balance Sheet at cost adjusted in respect of post-acquisition changes in the Group’s share of net assets, less any impairment in value. Loans advanced to equity accounted investments that have the characteristics of equity financing are also included in the investment held on the Consolidated Balance Sheet. If necessary, impairment losses on the carrying amount of an investment are reported within the Group’s share of equity accounted investments’ results in the Consolidated Income Statement. If the Group’s share of losses exceeds the carrying amount of an associate or joint venture, the carrying amount is reduced to nil and recognition of further losses is discontinued except to the extent that the Group has incurred obligations in respect of the associate or joint venture. Joint operations A joint operation is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the assets and obligations for the liabilities, relating to the arrangement. The Group’s investments in its joint operations are accounted for by recognising its assets and its liabilities, including its share of any assets or liabilities held jointly; its share of the revenue from the sale of the output by the joint operation; and its expenses, including its share of any expenses incurred jointly. Revenue recognition – Note 1 The Group recognises revenue in the amount of the price expected to be received for goods and services supplied at a point in time or over time, as contractual performance obligations are fulfilled and control of goods and services passes to the customer. It excludes trade discounts and value-added tax/sales tax. Revenue derived from sale of goods (sources other than construction contracts) The Group manufactures and distributes a diverse range of building materials and products. Whilst there are a number of different activities across the Group; recognition of revenue from the sale of goods is similar; being at the point in time when control is deemed to pass to the customer upon leaving a CRH premises or upon delivery to a customer depending on the terms of the sale. Contracts do not contain multiple performance obligations (as defined by IFRS 15 Revenue from Contracts with Customers Across the Group, goods are often sold with discounts or rebates based on cumulative sales over a period. This variable consideration is only recognised when it is highly probable that it will not be subsequently reversed and is recognised using the most likely amount or expected value methods, depending on the individual contract terms. In the application of appropriate revenue recognition, judgement is exercised by management in the determination of the likelihood and quantum of such items based on experience and historical trading patterns. The Group is deemed to be a principal to an arrangement when it controls a promised good or service before transferring them to a customer; and accordingly recognises revenue on a gross basis. Where the Group is determined to be an agent to a transaction, based on the principal of control; the net amount retained after the deduction of any costs to the principal is recognised as revenue. Within the non-construction Revenue derived from construction contracts The Group enters into a number of construction contracts, to complete large construction projects. Contracts usually commence and complete within one financial period and are generally fixed price. The Group typically recognises revenue within its construction contract businesses over time, as it performs its obligations. Management believe this best reflects the transfer of control to the customer by providing a faithful depiction of primarily the enhancement of a customer controlled asset or the construction of an asset with no alternative use. The percentage-of-completion percentage-of-completion Some of the Group’s construction contracts may contain forms of variable consideration that can either increase or decrease the transaction price. Variable consideration is estimated based on the most likely amount or expected value methods (depending on the contract terms) and the transaction price is adjusted to the extent it is probable that a significant reversal of revenue recognised will not occur. In some instances a customer can be billed and revenue recognised in the period subsequent to the contracted work being completed when items such as variable consideration are agreed with the customer. Recognition of contract assets and liabilities In our construction contract businesses, amounts are billed as work progresses in accordance with pre-agreed When consideration is received in advance of work being performed, or we have billed an amount to a customer that is in excess of revenue recognised on the contract; this is recognised as a contract liability within Trade and Other Payables (note 20); and the revenue is generally recognised in the subsequent period when the right to recognise revenue has been determined. As a result, advance payments received for construction contract arrangements are not considered a significant form of financing. Cumulative costs incurred, net of amounts transferred to cost of sales, after deducting onerous provisions, provisions for contingencies and payments on account not matched with revenue, are included as construction contract balances in inventories (note 18). Cost includes all expenditure directly related to specific projects and an allocation of fixed and variable overheads incurred in the Group’s contract activities based on normal operating capacity. The Group’s contracts generally are for a duration of less than one year and therefore the Group does not capitalise incremental contract costs; instead expensing as incurred, as permitted by the practical expedient under IFRS 15. Onerous contracts and warranties When a contract is identified as being onerous (i.e. its unavoidable cost exceeds the economic benefit of the contract), a provision is created; being the lower of costs to complete the contract and the cost of exiting the contract. The Group recognises a provision for assurance-type (standard) warranties offered across the Group under its terms and conditions in accordance with IAS 37. The Group provides assurance-type warranties for general repairs and does not typically provide service-type (extended) warranties. Segment reporting – Note 2 Operating segments are reported in a manner consistent with the internal organisational and management structure and the internal reporting information provided to the Chief Operating Decision Maker who is responsible for allocating resources and assessing performance of the operating segments. Assets and liabilities held for sale – Note 3 Non-current Non-current Property, plant and equipment and intangible assets are not depreciated or amortised once classified as held for sale. The Group ceases to use the equity method of accounting from the date on which an interest in a joint venture or associate becomes held for sale. Non-current Discontinued operations – Note 3 Discontinued operations are reported when a component of the Group, that represents a separate major line of business or geographical area of operation, has been disposed of, or when a sale is highly probable; and its operations and cash flows can be clearly distinguished, operationally and for financial reporting purposes, from the rest of the Group and is classified as held for sale or has been disposed of. The Group classifies a non-current In the Consolidated Income Statement, discontinued operations are excluded from the results of continuing operations and are presented as a single amount as profit or loss after tax from discontinued operations. Corresponding notes to the Consolidated Income Statement exclude amounts for discontinued operations, unless stated otherwise. Share-based payments – Note 9 The Group operates a number of equity-settled share-based payment plans. Its policy in relation to the granting of share options and awards under these plans, together with the nature of the underlying market and non-market Awards under the Performance Share Plans 25% of the awards under

Revenue	1. Revenue CRH is a leading global diversified building materials group which manufactures and supplies a diverse range of superior building materials and products for use in the construction and maintenance of infrastructure, housing and commercial products. Our materials and products are used extensively, in construction projects of all sizes, all across the world. As discussed in more detail in note 2, the Group has three operating segments (as identified under IFRS 8 Operating Segments Americas Materials Europe Materials Our Building Products The divestment of our Europe Distribution business (excluding DIY Benelux), formerly part of the Building Products segment, was completed in 2019. As a result, it has been classified as discontinued operations in the current year; its performance in this year and comparative years is therefore part of discontinued operations. As referenced above, DIY Benelux was separately divested in 2018 and therefore its performance up to the date of divestment is shown as part of continuing operations in 2018 and 2017. As a result of the more simplified operating structure implemented on 1 January 2019, the classification of reported revenue into the principal activities and products below has been amended to better reflect the basis on which management now reviews its businesses. Accordingly, the revenue formerly disaggregated across perimeter protection, shutters & awnings, network access products, architectural and precast products has now been reorganised and presented in two new categories: architectural products and infrastructure products. Comparative amounts for 2018 have been restated where necessary to reflect the new format for disaggregation of revenue. A. Disaggregated revenue In the following tables, revenue is disaggregated by primary geographic market and by principal activities and products. Due to the diversified nature of the Group, the basis on which management reviews its businesses varies across the Group. Geography is the primary basis for the Americas Materials and Europe Materials businesses; while activities and products are used for the Building Products businesses. Revenue from external customers (as defined in IFRS 8) attributable to the country of domicile and all foreign countries of operation greater than 10% are included below.

Segment Information	2. Segment Information Effective 1 January 2019 the Group implemented a simplified new structure reducing its operating segments from six to three: Americas Materials, Europe Materials (formerly Europe Heavyside and Asia), and a new Building Products segment. The Building Products segment brings together our former Americas Products, Europe Lightside and, up to its disposal, Europe Distribution segments. Comparative segment amounts for 2018 and 2017 have been restated where necessary to reflect the new format for segmentation. The segments reflect the Group’s organisational structure and the nature of the financial information reported to and assessed by the Group Chief Executive and Finance Director, who are together determined to fulfil the role of Chief Operating Decision Maker (as defined in IFRS 8). No operating segments have been aggregated to form these reportable segments. The principal factors employed in the identification of the three segments reflected in this note include: • the Group’s organisational structure in 2019 (during 2019 each divisional President fulfilled the role of “segment manager” as outlined in IFRS 8); • the nature of the reporting lines to the Chief Operating Decision Maker (as defined in IFRS 8); • the structure of internal reporting documentation such as management accounts and budgets; and • the degree of homogeneity of products and services within each of the segments from which revenue is derived The Chief Operating Decision Maker monitors the operating results of segments separately in order to allocate resources between segments and to assess performance. Segment performance is predominantly evaluated based on operating profit. As performance is also evaluated using operating profit before depreciation, amortisation and impairment (EBITDA (as defined)*), supplemental information based on EBITDA (as defined)* is provided overleaf. Given that net finance costs and income tax are managed on a centralised basis, these items are not allocated between operating segments for the purposes of the information presented to the Chief Operating Decision Maker and are accordingly omitted from the detailed segmental analysis overleaf. There are no asymmetrical allocations to reporting segments which would require disclosure. *  EBITDA is defined as earnings before interest, taxes, depreciation, amortisation, asset impairment charges, profit on disposals and the Group’s share of equity accounted investments’ profit after tax.

Assets Held for Sale and Discontinued Operations	3. Assets Held for Sale and Discontinued Operations A. Profit on disposal of discontinued operations In October 2019, the Group completed the divestment of its Europe Distribution business, formerly part of our Building Products segment. With the exception of our Europe Distribution business, no other businesses divested in 2019 are considered to be either separate major lines of business or geographical areas of operation and therefore do not constitute discontinued operations as defined in IFRS 5 Non-Current Assets Held for Sale and Discontinued Operations In January 2018, the Group completed the divestment of its 100% holding in Allied Building Products, the trading name of our former Americas Distribution segment, which was considered a discontinued operation in 2018 and was classified accordingly. Assets and liabilities that met the IFRS 5 criteria at 31 December 2019 have not been separately disclosed as held for sale as they were not considered material in the context of the Group.

See note 3 for further details. Changes in tax rates The total tax charge in future periods will be affected by any changes to the tax rates in force in the countries in which the Group operates. Excess of capital allowances over depreciation The current tax charge will also be impacted by changes in the excess of tax depreciation (capital allowances) over accounting depreciation. Based on current capital investment plans, the Group expects to continue to be in a position to claim capital allowances in excess of depreciation in future years. Investments in subsidiaries Given management’s intention not to unwind temporary differences in respect of its investment in subsidiaries or tax exemptions and credits being available in the majority of jurisdictions in which the Group operates, the aggregate amount of deferred tax liabilities on temporary differences which have not been recognised would be immaterial.

Goodwill arising on acquisition since that date is capitalised at cost. Cash-generating units Goodwill acquired through business combination activity has been allocated to cash-generating determined in accordance with IFRS 8. A total of 25 (2018: 26) CGUs have been identified and these are analysed between the three business segments below. All businesses within the various CGUs exhibit similar and/or consistent profit margin and asset intensity characteristics. Assets, liabilities, deferred tax and goodwill have been assigned to the CGUs on a reasonable and consistent basis. Cash-generating units Goodwill 2019 2018 2019 € 2018 € Americas Materials 7 7 3,558 3,441 Europe Materials 16 16 2,354 2,280 Building Products 2 3 2,182 2,395 Total Group 25 26 8,094 8,116 Impairment testing methodology and results Goodwill is subject to impairment testing on an annual basis. The recoverable amount of 25 CGUs is determined based on a value-in-use The cash flow forecasts are primarily based on a five-year strategic plan document formally approved by the Board of Directors and specifically exclude the impact of future development activity. These cash flows are projected forward for an additional five years to determine the basis for an annuity-based terminal value, calculated on the same basis as the Group’s acquisition modelling methodology. As in prior years, the terminal value is based on a 20-year 30-year value-in-use pre-tax The 2019 annual goodwill impairment testing process has resulted in no intangible asset impairments. The 2018 annual goodwill impairment testing process resulted in an impairment of € Key sources of estimation uncertainty The cash flows have been arrived at taking account of the Group’s strong financial position, its established history of earnings and cash flow generation and the nature of the building materials industry, where product obsolescence is very low. However, expected future cash flows are inherently uncertain and are therefore liable to material change over time. The key assumptions employed in arriving at the estimates of future cash flows factored into impairment testing are subjective and include projected EBITDA (as defined)* margins, net cash flows, discount rates used and the duration of the discounted cash flow model. Significant under-performance in any of CRH’s major CGUs may give rise to a material write-down Significant goodwill amounts The goodwill allocated to the Americas Cement (Americas Materials segment) and the Americas Building Products (Building Products segment) CGUs account for between 18% and 23% of the total carrying amount shown on page 166. The goodwill allocated to each of the remaining CGUs is less than 10% of the total carrying value in all other cases. The additional disclosures required for the two CGUs with significant goodwill are as follows: Americas Americas 2019 2018 2019 2018 Goodwill allocated to the cash-generating unit at balance sheet date € € € € Discount rate applied to the cash flow projections (real pre-tax) 7.6% 8.2% 8.4% 9.1% Average EBITDA (as defined)* margin over the initial 5-year 39.1% 37.9% 18.3% 15.3% Value-in-use € € € € Excess of value-in-use € € € € The key assumptions and methodology used in respect of these two CGUs are consistent with those described above. The values applied to each of the key estimates and assumptions are specific to the individual CGUs and were derived from a combination of internal and external factors based on historical experience and took into account the cash flows specifically associated with these businesses. The cash flows and annuity-based terminal value were projected in line with the methodology disclosed above. The Americas Cement and Americas Building Products CGUs are not included in the CGUs referred to in the ‘Sensitivity analysis’ section below.

Capital and Financial Risk Management	24. Capital and Financial Risk Management Capital management Overall summary The primary objectives of CRH’s capital management strategy are to ensure that the Group maintains a strong credit rating to support its business and to create shareholder value by managing the debt and equity balance and the cost of capital. The Group is committed to optimising the use of its balance sheet within the confines of the overall objective to maintain an investment grade credit rating. The capital structure of the Group, which comprises net debt and capital and reserves attributable to the Company’s equity holders, may be summarised as follows: 2019 € 2018 € Capital and reserves attributable to the Company’s equity holders 16,940 16,029 Net debt 6,705 6,984 Capital and net debt 23,645 23,013 The Board periodically reviews the capital structure of the Group, including the cost of capital and the risks associated with each class of capital. The Group manages and, if necessary, adjusts its capital structure taking account of underlying economic conditions; any material adjustments to the Group’s capital structure in terms of the relative proportions of debt and equity are approved by the Board. In order to maintain or adjust the capital structure, the Group may issue new shares, dispose of assets, amend investment plans, alter dividend policy or return capital to shareholders. Dividend cover for the year ended 31 December 2019 amounted to 2.90x (2018: 4.20x). No changes were made in the objectives or policies during 2019. Financial risk management objectives and policies The Group uses financial instruments throughout its businesses: interest-bearing loans and borrowings, cash and cash equivalents and leases are used to finance the Group’s operations; trade receivables and trade payables arise directly from operations; and derivatives, principally interest rate and currency swaps and forward foreign exchange contracts, are used to manage interest rate risks and currency exposures and to achieve the desired profile of borrowings. With respect to interest-bearing loans and borrowings and interest rate swaps, the Group is aware of plans to phase out the current benchmark for lending rates (Inter-bank Offered Rates - IBOR), and replace it with alternative benchmarks or reference rates. The Group is currently performing an assessment of the impact of the benchmark switch. The Group does not trade in financial instruments nor does it enter into any leveraged derivative transactions. The Group’s corporate treasury function provides services to the business units, co-ordinates The Group’s hedging activity is based on observable economic relationships, when there is confidence that such relationships will continue for the foreseeable future. Matching critical terms such as notional amount, tenor, timing and currency, the Group establishes relationships between a hedge item and hedge instrument where directional response to changes in fair value, driven by underlying economic conditions, are opposing and proportional in equal measure being an economic relationship under IFRS 9. Hedging ratios of one to one are used throughout all hedging activity as the hedge item and hedge instrument are of the same type and currency. The hedges employed mitigate identified risks and have consistently demonstrated close economic relationships. Ineffectiveness between the hedge item and hedge instrument are immaterial in the overall context of the Group. The main risks attaching to the Group’s financial instruments are interest rate risk, foreign currency risk, credit risk, liquidity risk and commodity price risk. The Board reviews and agrees policies for the prudent management of each of these risks as documented below. Interest rate risk The Group’s exposure to market risk for changes in interest rates stems predominantly from its long-term debt obligations. Interest cost is managed using a mix of fixed and floating rate debt. With the objective of managing this mix in a cost-efficient manner, the Group enters into interest rate swaps, under which the Group contracts to exchange, at predetermined intervals, the difference between fixed and variable interest amounts calculated by reference to a pre-agreed The majority of these swaps are designated under IFRS 9 to hedge underlying debt obligations and qualify for hedge accounting treatment; undesignated financial instruments are termed “not designated as hedges” in the analysis of derivative financial instruments presented in note 27. The Group’s interest rate hedging strategy and activity employs the premise that changes in macro-economic factors are reflected in current interest rates. In the economic relationship the relative value of the fixed rate at which a bond was issued will change in line with market interest rates and a floating rate swap will counterbalance changes in the bond’s fair value. A hypothetical derivative is used to replicate the impact that changes in market interest rates could have on the fixed rate bond (hedged item) which is measured against the interest rate swap (hedge instrument). A hedge ratio of one to one is established. Potential sources of ineffectiveness comprise the timing of floating rate resets and counterparty credit adjustments to the interest rate swap. Past observations on interest rate movements provide evidence that such relationships will continue for the foreseeable future. The notional amount of interest rate swaps is set out in note 23. The following table demonstrates the impact on profit before tax and total equity of a range of possible changes in the interest rates applicable to net floating rate borrowings, with all other variables held constant. These impacts are calculated based on the closing balance sheet for the relevant period and assume all floating interest rates and interest curves change by the same amount. For profit before tax, the impact shown is the impact on closing balance sheet floating rate net debt for a full year while for total equity the impact shown is the impact on the value of financial instruments. Percentage change in cost of +/- Impact on profit before tax 2019 +/- € 2018 +/- € 2017 +/- € Impact on total equity 2019 -/+ € 2018 -/+ € 2017 -/+ € (i) Sensitivity analysis for cost of borrowing has been presented for continuing operations only. Foreign currency risk Due to the nature of building materials, which in general have a low value-to-weight Given the Group’s presence in 30 countries worldwide, the principal foreign exchange risk arises from fluctuations in the euro value of the Group’s net investment in a wide basket of currencies other than the euro; such changes are reported separately within the Consolidated Statement of Comprehensive Income. A currency profile of the Group’s net debt and net worth is presented in note 23. The Group’s established policy is to spread its net worth across the currencies of its various operations with the objective of limiting its exposure to individual currencies and thus promoting consistency with the geographical balance of its operations. In order to achieve this objective, the Group manages its borrowings, where practicable and cost effective, to hedge a portion of its foreign currency assets. Hedging is done using currency borrowings in the same currency as the assets being hedged or through the use of other hedging methods such as currency swaps. The Group’s foreign exchange hedging strategy and activity is based on the assumption that changes in international economic factors are reflected in current foreign exchange rates and impacts the translation of the Group’s non-euro net assets. The economic relationship, being the translation impact of the Group’s net investment in non-euro subsidiaries (hedge item) is hedged against a foreign currency swap (hedge instrument) to counterbalance movements in foreign currency rates. The Group identifies certain portions of foreign currency net investments where foreign currency translation movements can be mitigated through the use of currency swaps in the same currency pairing. A hedge ratio of one to one is established. As at 31 December 2019, the notional amount of hedged net investments was € € The following table demonstrates the sensitivity of profit before tax and equity to selected movements in the relevant euro/US Dollar exchange rate (with all other variables held constant); the US Dollar has been selected as the appropriate currency for this analysis given the materiality of the Group’s activities in the US. The impact on profit before tax is based on changing the euro/US Dollar exchange rate used in calculating profit before tax for the period. The impact on total equity and financial instruments is calculated by changing the euro/US Dollar exchange rate used in measuring the closing balance sheet. Percentage change in relevant € +/- 5% Impact on profit before tax 2019 -/+ € 2018 -/+ € 2017 -/+ € Impact on total equity* 2019 -/+ € 2018 -/+ € 2017 -/+ € * Includes the impact on financial instruments which is as follows: 2019 +/- € 2018 +/- € 2017 +/- € (i)   Sensitivity analysis for exchange rates has been presented for continuing operations only. Financial instruments include deposits, money market funds, commercial papers, bank loans, medium-term notes and other fixed term debt, interest rate swaps, commodity swaps and foreign exchange contracts. They exclude trade receivables and trade payables. Credit/counterparty risk In addition to cash at bank and in hand, the Group holds significant cash balances which are invested on a short-term basis and are classified as cash equivalents (see note 25). These deposits and other financial instruments (principally certain derivatives and loans and receivables included within financial assets) give rise to credit risk on amounts due from counterparty financial institutions (stemming from their insolvency or a downgrade in their credit ratings). Credit risk is managed by limiting the aggregate amount and duration of exposure to any one counterparty primarily depending on its credit rating and by regular review of these ratings. Acceptable credit ratings are high investment-grade ratings - in general - counterparties have ratings of A3/A- In its worldwide insurance programme, the Group carries appropriate levels of insurance for typical business risks (including product liability) with various leading insurance companies. However, in the event of the failure of one or more of its insurance counterparties, the Group could be impacted by losses where recovery from such counterparties is not possible. Credit risk arising in the context of the Group’s operations is not significant with the total loss allowance at the balance sheet date amounting to 3.6% of gross trade receivables (2018: 3.7%). Information in relation to the Group’s credit risk management of trade receivables is provided in note 19. Amounts receivable from related parties (notes 19 and 34) are immaterial. Factoring and credit guarantee arrangements are employed in certain of the Group’s operations where deemed to be of benefit by operational management. Liquidity risk The principal liquidity risks faced by the Group stem from the maturation of debt obligations and derivative transactions. A downgrade of CRH’s credit ratings may give rise to increases in funding costs in respect of future debt and may impair the Group’s ability to raise funds on acceptable terms. The Group’s corporate treasury function ensures that sufficient resources are available to meet such liabilities as they fall due through a combination of cash and cash equivalents, cash flows and undrawn committed bank facilities. Flexibility in funding sources is achieved through a variety of means including (i) maintaining cash and cash equivalents only with a diverse group of highly-rated The undrawn committed facilities available to the Group as at the balance sheet date are quantified in note 26; these facilities span a wide number of highly-rated financial institutions thus minimising any potential exposure arising from concentrations in borrowing sources. The repayment schedule (analysed by maturity date) applicable to the Group’s outstanding interest-bearing loans and borrowings as at the balance sheet date is also presented in note 26. The Group’s € Commodity price risk The principal commodity price risks are identified in a variety of highly probable and active commodity contracts where a significant part of the price to be paid relies on a reference to specific floating price indices (usually US Dollar) for a specific period. Programmes are in place to hedge the quantities and qualities of commodity products, including coal, high sulphur fuel oil, diesel, electricity and carbon credits. The aim of the programmes is to neutralise the variability in the Consolidated Income Statement as a result of changes in associated commodity indices over a timeframe of approximately five years (2018: three years). A hedge ratio of one to one is established. Fixed price swap contracts in the entity’s operating currency are used to hedge the same specific floating index risk and currency risk where it is determined that those risks are better managed at a fixed price rather than being exposed to uncontrollable price fluctuations due to the floating price index element of the contract. Sources of ineffectiveness can relate to timing of cash flows and counterparty credit risk adjustments. The derivative contracts qualify for cash flow hedge accounting under IFRS 9 and the fair values by maturity are set out in note 27. The notional and fair values in respect of derivative contracts as at 31 December 2019 and 31 December 2018 were as follows: Profile of commodity products As at 31 December 2019 As at 31 December 2018 Notional value € Fair value € Notional value € Fair value € Commodity contracts 105 - 162 - Derivative liability - - - (27) The tables below show the projected contractual undiscounted total cash outflows (principal and interest) arising from the Group’s trade and other payables, gross debt and derivative financial instruments.

Due to the extended timeframe associated with many of the insurances, a significant proportion of the total provision is subject to periodic actuarial valuation. The projected cash flows underlying the discounting process are established through the application of actuarial triangulations, which are extrapolated from historical claims experience. The triangulations applied in the discounting process indicate that the Group’s insurance provisions have an average life of five years (2018: five years). (ii) This provision comprises obligations governing site remediation, restoration and environmental works to be incurred in compliance with either local or national environmental regulations together with constructive obligations stemming from established best practice.

Retirement Benefit Obligations	30. Retirement Benefit Obligations The Group operates either defined benefit or defined contribution pension schemes in all of its principal operating areas. The disclosures included below relate to all pension schemes in the Group. The Group operates defined benefit pension schemes in Belgium, Brazil, Canada, France, Germany, Italy, the Netherlands, the Philippines, the Republic of Ireland, Romania, Serbia, Slovakia, Switzerland, the UK and the US. The Group has a mixture of funded and unfunded defined benefit pension schemes. The net liability of the funded schemes is € € € € € € Funded defined benefit schemes in the Republic of Ireland, Switzerland and the UK are administered by separate funds that are legally distinct from the Group under the jurisdiction of Trustees. The Trustees of these pension funds are required by law and by their Articles of Association to act in the best interests of the scheme participants and are responsible for the definition of investment strategy and for scheme administration. Other schemes are also administered in line with the local regulatory environment. The level of benefits available to most members depends on length of service and either their average salary over their period of employment or their salary in the final years leading up to retirement. The Group’s pension schemes in Switzerland are contribution-based schemes with guarantees to provide further contributions in the event that certain targets are not met, largely in relation to investment return and the annuity conversion factor on retirement. Defined benefit pension schemes - principal risks Through its defined benefit pension and jubilee schemes, long-term service commitments and post-retirement healthcare plans, the Group is exposed to a number of risks, the most significant of which are detailed below: Asset volatility: Employee Benefits Given the maturity of certain of the Group’s funded defined benefit pension schemes, de-risking Discount rates: Inflation risk: Longevity risk: Aggregation For the purposes of the disclosures which follow; the schemes in Belgium, France, Germany, Italy, the Netherlands, the Republic of Ireland and Slovakia have been aggregated into a “Eurozone” category on the basis of common currency and financial assumptions; schemes in Brazil, the Philippines, Romania, Serbia and the UK have been aggregated into an “Other” category. Financial assumptions—scheme liabilities The major long-term assumptions used by the Group’s actuaries in the computation of scheme liabilities and post-retirement healthcare obligations are as follows: Eurozone Switzerland United States and Canada 2019 % 2018 % 2017 % 2019 % 2018 % 2017 % 2019 % 2018 % 2017 % Rate of increase in: - salaries 3.37 3.50 3.59 1.50 1.50 1.25 3.37 3.38 3.27 - pensions in payment 1.46 1.62 1.70 - - - - - - Inflation 1.50 1.65 1.75 1.00 1.00 0.75 2.00 2.00 2.00 Discount rate 1.43 2.12 2.05 0.30 0.85 0.70 3.14 4.10 3.52 Medical cost trend rate n/a n/a n/a n/a n/a n/a 5.18 1.55 6.33 The mortality assumptions employed in determining the present value of scheme liabilities under IAS 19 represent actuarial best practice in the relevant jurisdictions, taking account of mortality experience and industry circumstances. For schemes in the Republic of Ireland and the UK, the mortality assumptions used are in accordance with the underlying funding valuations. For the Group’s most material schemes, the future life expectations factored into the relevant valuations, based on retirement at 65 years of age for current and future retirees, are as follows: Republic of Ireland Switzerland United States and Canada 2019 2018 2017 2019 2018 2017 2019 2018 2017 Current retirees - male 23.0 22.4 22.7 22.6 22.5 22.4 20.2 20.1 20.6 - female 24.5 24.1 24.4 24.7 24.5 24.4 22.3 22.6 23.1 Future retirees - male 25.4 24.9 25.5 24.8 24.7 24.6 22.1 22.0 22.3 - female 26.8 26.4 27.0 26.8 26.7 26.6 24.2 24.5 24.7 The above data allows for future improvements in life expectancy.

Actuarial valuations - funding requirements and future cash flows In accordance with statutory requirements in the Republic of Ireland and minimum funding requirements in the UK, additional annual contributions and lump-sum payments are required to certain of the schemes in place in those jurisdictions. The funding requirements in relation to the Group’s defined benefit schemes are assessed in accordance with the advice of independent and qualified actuaries and valuations are prepared in this regard either annually, where local requirements mandate that this be done, or at triennial intervals at a maximum in all other cases. In the Republic of Ireland and the UK, either the attained age or projected unit credit methods are used in the valuations. In the Netherlands and Switzerland, the actuarial valuations reflect the current unit method, while the valuations are performed in accordance with the projected unit credit methodology in Germany. In the US, valuations are performed using a variety of actuarial cost methodologies - current unit, projected unit and aggregate cost. In Canada, the projected unit credit method is used in valuations. The dates of the funding valuations range from March 2016 to January 2019. In general, funding valuations are not available for public inspection; however, the results of valuations are advised to the members of the various schemes on request.

(ii) The Income Shares, which represent 5.86% of the total issued share capital, were created on 29 August 1988 for the express purpose of giving shareholders the choice of receiving dividends on either their Ordinary Shares or on their Income Shares (by notice of election to the Company). The Income Shares carried a different tax credit to the Ordinary Shares. The creation of the Income Shares was achieved by the allotment of fully paid Income Shares to each shareholder equal to his/her holding of Ordinary Shares but the shareholder is not entitled to an Income Share certificate, as a certificate for Ordinary Shares is deemed to include an equal number of Income Shares and a shareholder may only sell, transfer or transmit Income Shares with an equivalent number of Ordinary Shares. Income Shares carry no voting rights. Due to changes in Irish tax legislation since the creation of the Income Shares, dividends on the Company’s shares no longer carry a tax credit. As elections made by shareholders to receive dividends on their holding of Income Shares were no longer relevant, the Articles of Association were amended on 8 May 2002 to cancel such elections. (iii) During 2019 43,750,000 Ordinary Shares (including Income Shares) were cancelled. The amount paid to repurchase these shares was initially recognised in Treasury Shares/own shares and was transferred to retained income on cancellation.

The Interim 2018 dividends were also paid wholly in cash in September 2018. Share schemes The aggregate number of shares which may be committed for issue in respect of any share option scheme, savings-related share option scheme, share participation scheme, performance share plan or any subsequent option scheme or share plan, may not exceed 10% of the issued ordinary share capital from time to time. Share option schemes Details of share options granted under the Company’s Share Option Schemes and the terms attaching thereto are provided in note 9 to the financial statements. Under these schemes, options over a total of 1,147,149 Ordinary Shares were exercised during the financial year (2018: 796,944; 2017: 1,589,335).

In 2019, the appropriation was satisfied by the purchase of 148,846 shares (2018: 59,666 satisfied by the issue of new shares; 103,650 by the re-issue of Treasury Shares). The Ordinary Shares appropriated pursuant to these schemes were issued at market value on the dates of appropriation). The shares issued pursuant to these schemes are excluded from the scope of IFRS 2 and are hence not factored into the expense computation and the associated disclosures in note 9.

Basis of Preparation	Basis of Preparation The Consolidated Financial Statements of CRH plc have been prepared in accordance with I n CRH plc, the Parent Company, is a publicly traded limited company incorporated and domiciled in the Republic of Ireland. The Consolidated Financial Statements, which are presented in euro millions, have been prepared under the historical cost convention as modified by the measurement at fair value of share-based payments, retirement benefit obligations and certain financial assets and liabilities including derivative financial instruments. The accounting policies set out below have been applied consistently by all of the Group’s subsidiaries, joint ventures and associates to all periods presented in the Consolidated Financial Statements. In accordance with Section 304 of the Companies Act 2014, the Company is availing of the exemption from presenting its individual profit and loss account to the Annual General Meeting and from filing it with the Registrar of Companies.
Adoption of IFRS and International Financial Reporting Interpretations Committee (IFRIC) interpretations	Adoption of IFRS and International Financial Reporting Interpretations Committee (IFRIC) interpretations The following new standards, interpretations and standard amendments became effective for the Group as of 1 January 2019: • IFRS 16 Leases • IFRIC 23 Uncertainty over Income Tax Treatments • Amendments to IFRS 9 Financial Instruments • Amendments to IAS 19 Employee Benefits • Amendments to IAS 28 Investments in Associates and Joint Ventures • Annual Improvements 2015 – 2017 Cycle The new standards, interpretations and standard amendments did not result in a material impact on the Group’s results, with the exception of IFRS 16 which is detailed below. IFRS 16 Leases IFRS 16 replaces IAS 17 Leases low-value non-lease right-of-use Provisions, Contingent Liabilities and Contingent Assets The adoption of IFRS 16 had a material impact on the Group’s Consolidated Financial Statements and certain key financial metrics, which is quantified and further explained in the table overleaf. Primary statement line item / financial metric As at 1 January 2019 € Consolidated Balance Sheet Property, plant and equipment (i) (ii) +1,939 Lease liabilities; net debt (i) (ii) +1,954 For the year ended € Consolidated Income Statement Depreciation (i) +334 Finance costs +69 EPS (i) (iii) -3c Consolidated Statement of Cash Flows Net cash flow from operating activities +317 Net cash flow from financing activities -317 (i) The operating profit and depreciation impact of IFRS 16 on discontinued operations included above are + € € right-of-use € (ii) The impact of the adoption of IFRS 16 on property, plant and equipment and net debt is net of existing finance leases ( € right-of-use (iii) The impact of the adoption of IFRS 16 on operating profit for the year ended 31 December 2019 is € Income Statement Cost of sales and operating costs (excluding depreciation) have decreased, as the Group previously recognised operating lease expenses in either cost of sales or operating costs (depending on the nature of the relevant operations and of the lease). The Group’s operating lease expense for the year ended 31 December 2018 from continuing operations was € € Depreciation and finance costs have increased due to the capitalisation of a right-of-use Balance Sheet The Group has identified the minimum lease payments outstanding (including payments for renewal options which are reasonably certain to be exercised) and has applied the appropriate discount rate to calculate the present value of the lease liability and right-of-use A reconciliation of the operating lease commitment previously reported under IAS 17 to the discounted lease liability as at 1 January 2019 under IFRS 16 is as follows: As at 1 January 2019 € Operating lease commitment under IAS 17 1,911 Lease extensions beyond break date 632 Leases that are cancellable at any time 35 Existing IAS 17 finance leases (i) 23 Other lease payments not included in discounted lease liability under IFRS 16 (ii) (108) Undiscounted lease liability under IFRS 16 2,493 Less impact of discounting (516) Discounted lease liability under IFRS 16 1,977 (i) Existing IAS 17 finance leases are presented at discounted amounts as the impact of discounting on these leases is not considered material. (ii) Other lease payments not included in the discounted lease liability under IFRS 16 include payments related to short-term and low-value IFRS and IFRIC interpretations being adopted in subsequent years IFRS 17 Insurance Contracts In May 2017, the IASB issued IFRS 17. It is expected to be effective for reporting periods beginning on or after 1 January 2022, with presentation of comparative figures required. The Group is currently evaluating the impact of this standard on future periods. IFRS 3 Business Combinations In October 2018, the IASB issued amendments to IFRS 3, regarding the definition of a business. The amendments clarify that the process required to meet the definition of a business (together with inputs to create outputs) must be substantive; and, that the inputs and process must together significantly contribute to creating outputs. The definition of outputs has been narrowed to focus on goods and services provided to customers and other income from ordinary activities. In addition, the amendments indicate that an acquisition of primarily a single asset or group of similar assets is unlikely to meet the definition of a business. The amendments will be applied prospectively for business combinations and asset acquisitions occurring on or after 1 January 2020. The Group is finalising its review of the impact of this amendment, but does not expect the clarification to have a material impact on the value of acquisitions or additions to property, plant and equipment. Disclosure Initiative – Definition of Material (Amendments to IAS 1 and IAS 8) In October 2018, the IASB issued Definition of Material (Amendments to IAS 1 Presentation of Financial Statements Accounting Policies, Changes in Accounting Estimates and Errors Interest Rate Benchmark Reform – Amendments to IFRS 9, IAS 39 and IFRS 7 In September 2019, the IASB issued amendments to IFRS 9, IAS 39 Financial Instruments: Recognition and Measurement Financial Instruments: Disclosures The amendments provide mandatory temporary reliefs which enable hedge accounting to continue during the period of uncertainty before the replacement of an existing interest rate benchmark with an alternative nearly risk-free interest rate (an RFR). To the extent that a hedging instrument is altered so that its cash flows are based on an RFR, but the hedged item is still based on IBOR (or vice versa), there is no relief from measuring and recording any ineffectiveness that arises due to differences in their changes in fair value. The amendments are effective from 1 January 2020 and must be applied retrospectively. However, any hedge relationships that have previously been de-designated cannot be reinstated upon application, nor can any hedge relationships be designated with the benefit of hindsight. The Group is currently evaluating the impact of this amendment, but does not expect the amendment to have a material impact. There are no other IFRS or IFRIC interpretations that are effective subsequent to the CRH 2019 financial year-end
Key Accounting Policies which involve Estimates, Assumptions and Judgements	Key Accounting Policies which involve Estimates, Assumptions and Judgements The preparation of the Consolidated Financial Statements in accordance with IFRS requires management to make certain estimates, assumptions and judgements that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Management believes that the estimates, assumptions and judgements upon which it relies are reasonable based on the information available to it at the time that those estimates, assumptions and judgements are made. In some cases, the accounting treatment of a particular transaction is specifically dictated by IFRS and does not require management’s judgement in its application. Management considers that their use of estimates, assumptions and judgements in the application of the Group’s accounting policies are inter-related and therefore discuss them together below. Estimates and underlying assumptions are reviewed on an ongoing basis. Changes in accounting estimates may be necessary if there are changes in the circumstances or experiences on which the estimate was based or as a result of new information. The critical accounting policies which involve significant estimates, assumptions or judgements, the actual outcome of which could have a material impact on the Group’s results and financial position outlined below, are as follows: Impairment of goodwill – Note 16 In the year in which a business combination is effected and where some or all of the goodwill allocated to a particular cash-generating unit arose in respect of that combination, the cash-generating unit is tested for impairment prior to the end of the relevant annual period. Goodwill is subject to impairment testing on an annual basis and at any time during the year if an indicator of impairment is considered to exist. Where the carrying value exceeds the estimated recoverable amount (being the greater of fair value less costs of disposal and value-in-use), value-in-use, pre-tax Goodwill relating to associates and joint ventures is included in the carrying amount of the investment and is neither amortised nor individually tested for impairment. Where indicators of impairment of an investment arise in accordance with the requirements of IFRS 9, the carrying amount is tested for impairment by comparing its recoverable amount with its carrying amount. The impairment testing process requires management to make significant judgements and estimates regarding the future cash flows expected to be generated by cash-generating units to which goodwill has been allocated. Future cash flows relating to the eventual disposal of these cash-generating units and other factors may also be relevant to determine the fair value of goodwill. Management periodically evaluates and updates the estimates based on the conditions which influence these variables. A detailed discussion of the impairment methodology applied and key assumptions used by the Group in the context of goodwill is provided in note 16 to the Consolidated Financial Statements. The assumptions and conditions for determining impairments of goodwill reflect management’s best assumptions and estimates, but these items involve inherent uncertainties described above, many of which are not under management’s control. As a result, the accounting for such items could result in different estimates or amounts if management used different assumptions or if different conditions occur in future accounting periods. Retirement benefit obligations – Note 30 Costs arising in respect of the Group’s defined contribution pension schemes are charged to the Consolidated Income Statement in the period in which they are incurred. The Group has no legal or constructive obligation to pay further contributions in the event that the fund does not hold sufficient assets to meet its benefit commitments. The liabilities and costs associated with the Group’s defined benefit pension schemes (both funded and unfunded) are assessed either on the basis of the attained age, the projected unit credit, the current unit credit or the aggregate cost methods by professionally qualified actuaries and are arrived at using actuarial assumptions based on market expectations at the balance sheet date. The discount rates employed in determining the present value of the schemes’ liabilities are determined by reference to market yields at the balance sheet date on high-quality corporate bonds of a currency and term consistent with the currency and term of the associated post-employment benefit obligations. The net surplus or deficit arising on the Group’s defined benefit pension schemes, together with the liabilities associated with the unfunded schemes, are shown either within non-current non-current The defined benefit pension asset or liability in the Consolidated Balance Sheet comprises the total for each plan of the present value of the defined benefit obligation less the fair value of plan assets out of which the obligations are to be settled directly. Plan assets are assets that are held by a long-term employee benefit fund or qualifying insurance policies. Fair value is based on market price information and, in the case of published quoted securities; it is the published bid price. The value of any defined benefit asset is limited to the present value of any economic benefits available in the form of refunds from the plan and reductions in the future contributions to the plan. The Group’s obligation in respect of post-employment healthcare and life assurance benefits represents the amount of future benefit that employees have earned in return for service in the current and prior periods. The obligation is computed on the basis of the projected unit credit method and is discounted to present value using a discount rate equating to the market yield at the balance sheet date on high-quality corporate bonds of a currency and term consistent with the currency and estimated term of the post-employment obligations. Assumptions The assumptions underlying the actuarial valuations (including discount rates, rates of increase in future compensation levels, mortality rates and healthcare cost trends), from which the amounts recognised in the Consolidated Financial Statements are determined, are updated annually based on current economic conditions and for any relevant changes to the terms and conditions of the pension and post-retirement plans. These assumptions can be affected by (i) for the discount rate, changes in the rates of return on high-quality corporate bonds; (ii) for future compensation levels, future labour market conditions and (iii) for healthcare cost trend rates, the rate of medical cost inflation in the relevant regions. The weighted average actuarial assumptions used and sensitivity analysis in relation to the significant assumptions employed in the determination of pension and other post-retirement liabilities are contained in note 30 to the Consolidated Financial Statements. Whilst management believes that the assumptions used are appropriate, differences in actual experience or changes in assumptions may affect the obligations and expenses recognised in future accounting periods. The assets and liabilities of defined benefit pension schemes may exhibit significant period-on-period Provisions for liabilities – Note 28 A provision is recognised when the Group has a present obligation (either legal or constructive) as a result of a past event, it is probable that a transfer of economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. Where the Group anticipates that a provision will be reimbursed, the reimbursement is recognised as a separate asset only when it is virtually certain that the reimbursement will arise. The expense relating to any provision is presented in the Consolidated Income Statement net of any reimbursement. Provisions are measured at the present value of the expenditures expected to be required to settle the obligation. The increase in the provision due to the passage of time is recognised as an interest expense. Contingent liabilities arising on business combinations are recognised as provisions if the contingent liability can be reliably measured at its acquisition date fair value. Provisions are not recognised for future operating losses. Management is not aware of any potential changes to key assumptions that have a significant risk of causing a material adjustment to the carrying value of provisions within the next financial year; however due to the nature of some of our provisions, estimates may depend on the outcome of future events and need to be revised as circumstances change in future accounting periods. Refer to note 28 for the expected timing of outflows by provisions category. Environmental and remediation provisions The measurement of environmental and remediation provisions is based on an evaluation of currently available facts with respect to each individual site and considers factors such as existing technology, currently enacted laws and regulations and prior experience in remediation of sites. Inherent uncertainties exist in such evaluations primarily due to unknown conditions, changing governmental regulations and legal standards regarding liability, the protracted length of the clean-up Legal contingencies The status of each significant claim and legal proceeding in which the Group is involved is reviewed by management on a periodic basis and the Group’s potential financial exposure is assessed. If the potential loss from any claim or legal proceeding is considered probable, and the amount can be reliably estimated, a liability is recognised for the estimated loss. Because of the uncertainties inherent in such matters, the related provisions are based on the best information available at the time; the issues taken into account by management and factored into the assessment of legal contingencies include, as applicable, the status of settlement negotiations, interpretations of contractual obligations, prior experience with similar contingencies/claims, the availability of insurance to protect against the downside exposure and advice obtained from legal counsel and other third parties. As additional information becomes available on pending claims, the potential liability is reassessed and revisions are made to the amounts accrued where appropriate. Such revisions in the judgements and estimates of the potential liabilities could have an impact on the results of operations and financial position of the Group in future accounting periods. Insurance provisions Insurance provisions are subject to actuarial valuation and are based on actuarial triangulations which are extrapolated from historical claims experience. These provisions include claims which are classified as “incurred but not reported”, the status of which are reviewed periodically by management, in conjunction with appropriately qualified advisors. Changes in actuarial methodologies and assumptions, along with the receipt of new information, could have an impact on the financial position of the Group through recognition of additional, or release of, provisions in future accounting periods. Taxation – current and deferred – Notes 12 and 29 Current tax represents the expected tax payable (or recoverable) on the taxable profit for the year using tax rates enacted for the period. Any interest or penalties arising are included within current tax. Where items are accounted for outside of profit or loss, the related income tax is recognised either in other comprehensive income or directly in equity as appropriate. Deferred tax is recognised using the liability method on temporary differences arising at the balance sheet date between the tax bases of assets and liabilities and their carrying amounts in the Consolidated Financial Statements. However, deferred tax liabilities are not recognised if they arise from the initial recognition of goodwill. In addition, deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that, at the time of the transaction, affects neither accounting nor taxable profit or loss. For the most part, no provision has been made for temporary differences applicable to investments in subsidiaries and joint ventures as the Group is in a position to control the timing of reversal of the temporary differences and it is probable that the temporary differences will not reverse in the foreseeable future. However, a temporary difference has been recognised to the extent that specific assets have been identified for sale or where there is a specific intention to unwind the temporary difference in the foreseeable future. Due to the absence of control in the context of associates (significant influence only), deferred tax liabilities are recognised where appropriate in respect of CRH’s investments in these entities on the basis that the exercise of significant influence would not necessarily prevent earnings being remitted by other shareholders in the undertaking. Deferred tax is determined using tax rates (and laws) that have been enacted or substantively enacted by the balance sheet date and are expected to apply when the related deferred income tax asset is realised or the deferred income tax liability is settled. Deferred tax assets and liabilities are not subject to discounting. Deferred tax assets are recognised in respect of all deductible temporary differences, carry-forward of unused tax credits and unused tax losses to the extent that it is probable that taxable profits will be available against which the temporary differences can be utilised. The carrying amounts of deferred tax assets are subject to review at each balance sheet date and are reduced to the extent that future taxable profits are considered to be inadequate to allow all or part of any deferred tax asset to be utilised. The Group’s income tax charge is based on reported profit and enacted statutory tax rates, which reflect various allowances and reliefs and tax planning opportunities available to the Group in the multiple tax jurisdictions in which it operates. The determination of the Group’s provision for income tax requires certain judgements and estimates in relation to matters where the ultimate tax outcome may not be certain. The recognition or non-recognition year-end,
Basis of consolidation	Basis of consolidation The Consolidated Financial Statements include the financial statements of the Parent Company and all subsidiaries, joint ventures and associates, drawn up to 31 December each year. The financial year-ends of the Group’s subsidiaries, joint ventures and associates are co-terminous. Subsidiaries Subsidiaries are all entities over which the Group has control. The Group controls an entity when the Group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control ceases. A change in the ownership interest of a subsidiary without a change in control is accounted for as an equity transaction. When the Group holds less than the majority of voting rights, other facts and circumstances including contractual arrangements that give the Group power over the investee may result in the Group controlling the investee. The Group reassesses whether it controls an investee if, and when, facts and circumstances indicate that there are changes to the elements evidencing control. Non-controlling non-controlling non-controlling non-controlling Investments in associates and joint ventures – Notes 11 and 17 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 an entity, but is not control or joint control over those policies. A joint venture is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the joint venture. Joint control is the contractually agreed sharing of control of the arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control. The Group’s investments in its associates and joint ventures are accounted for using the equity method from the date significant influence/joint control is deemed to arise until the date on which significant influence/joint control ceases to exist or when the interest becomes classified as an asset held for sale. The Consolidated Income Statement reflects the Group’s share of profit after tax of the related associates and joint ventures. Investments in associates and joint ventures are carried in the Consolidated Balance Sheet at cost adjusted in respect of post-acquisition changes in the Group’s share of net assets, less any impairment in value. Loans advanced to equity accounted investments that have the characteristics of equity financing are also included in the investment held on the Consolidated Balance Sheet. If necessary, impairment losses on the carrying amount of an investment are reported within the Group’s share of equity accounted investments’ results in the Consolidated Income Statement. If the Group’s share of losses exceeds the carrying amount of an associate or joint venture, the carrying amount is reduced to nil and recognition of further losses is discontinued except to the extent that the Group has incurred obligations in respect of the associate or joint venture. Joint operations A joint operation is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the assets and obligations for the liabilities, relating to the arrangement. The Group’s investments in its joint operations are accounted for by recognising its assets and its liabilities, including its share of any assets or liabilities held jointly; its share of the revenue from the sale of the output by the joint operation; and its expenses, including its share of any expenses incurred jointly.
Revenue recognition	Revenue recognition – Note 1 The Group recognises revenue in the amount of the price expected to be received for goods and services supplied at a point in time or over time, as contractual performance obligations are fulfilled and control of goods and services passes to the customer. It excludes trade discounts and value-added tax/sales tax. Revenue derived from sale of goods (sources other than construction contracts) The Group manufactures and distributes a diverse range of building materials and products. Whilst there are a number of different activities across the Group; recognition of revenue from the sale of goods is similar; being at the point in time when control is deemed to pass to the customer upon leaving a CRH premises or upon delivery to a customer depending on the terms of the sale. Contracts do not contain multiple performance obligations (as defined by IFRS 15 Revenue from Contracts with Customers Across the Group, goods are often sold with discounts or rebates based on cumulative sales over a period. This variable consideration is only recognised when it is highly probable that it will not be subsequently reversed and is recognised using the most likely amount or expected value methods, depending on the individual contract terms. In the application of appropriate revenue recognition, judgement is exercised by management in the determination of the likelihood and quantum of such items based on experience and historical trading patterns. The Group is deemed to be a principal to an arrangement when it controls a promised good or service before transferring them to a customer; and accordingly recognises revenue on a gross basis. Where the Group is determined to be an agent to a transaction, based on the principal of control; the net amount retained after the deduction of any costs to the principal is recognised as revenue. Within the non-construction Revenue derived from construction contracts The Group enters into a number of construction contracts, to complete large construction projects. Contracts usually commence and complete within one financial period and are generally fixed price. The Group typically recognises revenue within its construction contract businesses over time, as it performs its obligations. Management believe this best reflects the transfer of control to the customer by providing a faithful depiction of primarily the enhancement of a customer controlled asset or the construction of an asset with no alternative use. The percentage-of-completion percentage-of-completion Some of the Group’s construction contracts may contain forms of variable consideration that can either increase or decrease the transaction price. Variable consideration is estimated based on the most likely amount or expected value methods (depending on the contract terms) and the transaction price is adjusted to the extent it is probable that a significant reversal of revenue recognised will not occur. In some instances a customer can be billed and revenue recognised in the period subsequent to the contracted work being completed when items such as variable consideration are agreed with the customer. Recognition of contract assets and liabilities In our construction contract businesses, amounts are billed as work progresses in accordance with pre-agreed When consideration is received in advance of work being performed, or we have billed an amount to a customer that is in excess of revenue recognised on the contract; this is recognised as a contract liability within Trade and Other Payables (note 20); and the revenue is generally recognised in the subsequent period when the right to recognise revenue has been determined. As a result, advance payments received for construction contract arrangements are not considered a significant form of financing. Cumulative costs incurred, net of amounts transferred to cost of sales, after deducting onerous provisions, provisions for contingencies and payments on account not matched with revenue, are included as construction contract balances in inventories (note 18). Cost includes all expenditure directly related to specific projects and an allocation of fixed and variable overheads incurred in the Group’s contract activities based on normal operating capacity. The Group’s contracts generally are for a duration of less than one year and therefore the Group does not capitalise incremental contract costs; instead expensing as incurred, as permitted by the practical expedient under IFRS 15. Onerous contracts and warranties When a contract is identified as being onerous (i.e. its unavoidable cost exceeds the economic benefit of the contract), a provision is created; being the lower of costs to complete the contract and the cost of exiting the contract. The Group recognises a provision for assurance-type (standard) warranties offered across the Group under its terms and conditions in accordance with IAS 37. The Group provides assurance-type warranties for general repairs and does not typically provide service-type (extended) warranties.
Segment reporting	Segment reporting – Note 2 Operating segments are reported in a manner consistent with the internal organisational and management structure and the internal reporting information provided to the Chief Operating Decision Maker who is responsible for allocating resources and assessing performance of the operating segments.
Assets and liabilities held for sale	Assets and liabilities held for sale – Note 3 Non-current Non-current Property, plant and equipment and intangible assets are not depreciated or amortised once classified as held for sale. The Group ceases to use the equity method of accounting from the date on which an interest in a joint venture or associate becomes held for sale. Non-current
Discontinued operations	Discontinued operations – Note 3 Discontinued operations are reported when a component of the Group, that represents a separate major line of business or geographical area of operation, has been disposed of, or when a sale is highly probable; and its operations and cash flows can be clearly distinguished, operationally and for financial reporting purposes, from the rest of the Group and is classified as held for sale or has been disposed of. The Group classifies a non-current In the Consolidated Income Statement, discontinued operations are excluded from the results of continuing operations and are presented as a single amount as profit or loss after tax from discontinued operations. Corresponding notes to the Consolidated Income Statement exclude amounts for discontinued operations, unless stated otherwise.
Share-based payments	Share-based payments – Note 9 The Group operates a number of equity-settled share-based payment plans. Its policy in relation to the granting of share options and awards under these plans, together with the nature of the underlying market and non-market Awards under the Performance Share Plans 25% of the awards under the 2014 Performance Share Plan are subject to a TSR (and hence market-based) vesting condition measured against a tailored sector peer group (2018 and 2017: 50%; with 25% being measured against a tailored sector peer group and 25% against the FTSE All-World non-market-based In 2019 a new RONA metric of 25% was introduced for awards made in 2019. The remaining 50% of awards granted under the 2014 Performance Share Plan are subject to a cumulative cash flow target (non-market-based) If awards which vest under the 2014 Performance Share Plan are allotted to an Employee Benefit Trust, an increase in nominal share capital and share premium are recognised accordingly on allotment. Savings-related Share Option Scheme The fair values assigned to options under the Savings-related Share Option Scheme are derived in accordance with the trinomial valuation methodology on the basis that the services to be rendered by employees as consideration for the granting of share options will be received over the vesting period, which is assessed as at the grant date. The cost is recognised, together with a corresponding increase in equity, over the period in which the performance and/or service conditions are fulfilled. The cumulative expense recognised at each reporting date until the vesting date reflects the extent to which the vesting period has expired and the Group’s best estimate of the number of equity instruments that will ultimately vest. The Consolidated Income Statement expense/credit for a period represents the movement in cumulative expense recognised at the beginning and end of that period. The cumulative charge to the Consolidated Income Statement is reversed only where an employee in receipt of share options leaves service prior to completion of the expected vesting period and those options forfeit in consequence. Where an award is cancelled, it is treated as if it is vested on the date of cancellation, and any expense not yet recognised for the award is recognised immediately. This includes any award where non-vesting The proceeds received net of any directly attributable transaction costs are credited to share capital (nominal value) and share premium when the options are exercised. The dilutive effect of outstanding options is reflected as additional share dilution in the determination of diluted earnings per share.
Property, plant and equipment	Property, plant and equipment – Note 15 The carrying value of property, plant and equipment (excluding leased right-of-use assets) of € Repair and maintenance expenditure is included in an asset’s carrying amount or recognised as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. All other repair and maintenance expenditure is charged to the Consolidated Income Statement during the financial period in which it is incurred. Borrowing costs incurred in the construction of major assets which take a substantial period of time to complete are capitalised in the financial period in which they are incurred. In the application of the Group’s accounting policy, judgement is exercised by management in the determination of residual values and useful lives. Depreciation and depletion is calculated to write off the book value of each item of property, plant and equipment over its useful economic life on a straight-line basis at the following rates: Land and buildings The book value of mineral-bearing land, less an estimate of its residual value, is depleted over the period of the mineral extraction in the proportion which production for the year bears to the latest estimates of proven and probable mineral reserves. Land, other than mineral-bearing land, is not depreciated. In general, buildings are depreciated at 2.5% per annum (p.a.). Plant and machinery These are depreciated at rates ranging from 3.3% p.a. to 20% p.a. depending on the type of asset. Plant and machinery includes transport which is, on average, depreciated at 20% p.a. Depreciation methods, useful lives and residual values are reviewed at each financial year-end. Impairment of property, plant and equipment The carrying values of items of property, plant and equipment are reviewed for indicators of impairment at each reporting date and are subject to impairment testing when events or changes in circumstances indicate that the carrying values may not be recoverable. Property, plant and equipment assets are reviewed for potential impairment by applying a series of external and internal indicators specific to the assets under consideration; these indicators encompass macroeconomic issues including the inherent cyclicality of the building materials sector, actual obsolescence or physical damage, a deterioration in forecast performance in the internal reporting cycle and restructuring and rationalisation programmes. Similar to the process for goodwill, where the carrying value exceeds the estimated recoverable amount (being the greater of fair value less costs of disposal and value-in-use), value-in-use, pre-tax
Business combinations	Business combinations – Note 32 The Group applies the acquisition method in accounting for business combinations. The cost of an acquisition is measured as the aggregate of the consideration transferred (excluding amounts relating to the settlement of pre-existing non-controlling To the extent that settlement of all or any part of consideration for a business combination is deferred, the fair value of the deferred component is determined through discounting the amounts payable to their present value at the date of exchange. The discount component is unwound as an interest charge in the Consolidated Income Statement over the life of the obligation. Any contingent consideration is recognised at fair value at the acquisition date and included in the cost of the acquisition. The fair value of contingent consideration at acquisition date is arrived at through discounting the expected payment (based on scenario modelling) to present value. In general, in order for contingent consideration to become payable, pre-defined The assets and liabilities arising on business combination activity are measured at their acquisition-date fair values. Contingent liabilities assumed in business combination activity are recognised as of the acquisition date, where such contingent liabilities are present obligations arising from past events and their fair value can be measured reliably. In the case of a business combination achieved in stages, the acquisition-date fair value of the acquirer’s previously-held equity interest in the acquiree is remeasured to fair value as at the acquisition date through profit or loss. When the initial accounting for a business combination is determined provisionally, any adjustments to the provisional values allocated to the consideration, identifiable assets or liabilities (and contingent liabilities, if relevant) are made within the measurement period, a period of no more than one year from the acquisition date.
Goodwill	Goodwill – Note 16 Goodwill arising on a business combination is initially measured at cost, being the excess of the cost of an acquisition over the fair value of the net identifiable assets and liabilities assumed at the date of acquisition and relates to the future economic benefits arising from assets which are not capable of being individually identified and separately recognised. Following initial recognition, goodwill is measured at cost less any accumulated impairment losses. If the cost of the acquisition is lower than the fair value of the net assets of the subsidiary acquired, the identification and measurement of the related assets and liabilities and contingent liabilities are revisited and the cost is reassessed with any remaining balance recognised immediately in the Consolidated Income Statement. The carrying amount of goodwill in respect of associates and joint ventures is included in investments accounted for using the equity method (i.e. within financial assets) in the Consolidated Balance Sheet. Where a subsidiary is disposed of or terminated through closure, the carrying value of any goodwill of that subsidiary is included in the determination of the net profit or loss on disposal/termination.
Intangible assets (other than goodwill) arising on business combinations	Intangible assets (other than goodwill) arising on business combinations – Note 16 An intangible asset is capitalised separately from goodwill as part of a business combination at cost (fair value at date of acquisition). Subsequent to initial recognition, intangible assets are carried at cost less any accumulated amortisation and any accumulated impairment losses. The carrying values of definite-lived intangible assets (the Group does not currently have any indefinite-lived intangible assets other than goodwill) are reviewed for indicators of impairment at each reporting date and are subject to impairment testing when events or changes in circumstances indicate that the carrying values may not be recoverable. Intangible assets are amortised on a straight-line basis. In general, definite-lived intangible assets are amortised over periods ranging from one to ten years, depending on the nature of the intangible asset. Amortisation periods, useful lives, expected patterns of consumption and residual values are reviewed at each financial year-end.
Leases	Leases – Notes 15 and 22 The Group enters into leases for a range of assets, principally relating to property. These property leases have varying terms, renewal rights and escalation clauses, including periodic rent reviews linked with a consumer price index and/or other indices. The Group also leases plant and machinery, vehicles and equipment. The terms and conditions of these leases do not impose significant financial restrictions on the Group. A contract contains a lease if it is enforceable and conveys the right to control the use of a specified asset for a period of time in exchange for consideration, which is assessed at inception. A right-of-use The lease liability is initially measured at the present value of the future minimum lease payments, discounted using the incremental borrowing rate or the interest rate implicit in the lease, if this is readily determinable, over the remaining lease term. Lease payments include fixed payments less any lease incentives receivable, variable payments that are dependent on a rate or index known at the commencement date, amounts expected to be paid under residual value guarantees and any payments for an optional renewal period and purchase and termination option payments, if the Group is reasonably certain to exercise those options. The lease term is the non-cancellable Incremental borrowing rates are calculated using a portfolio approach, based on the risk profile of the entity holding the lease and the term and currency of the lease. After initial recognition, the lease liability is measured at amortised cost using the effective interest method. It is remeasured when there is a change in future minimum lease payments or when the Group changes its assessment of whether it is reasonably certain to exercise an option within the contract. A corresponding adjustment is made to the carrying amount of the right-of-use The right-of-use right-of-use right-of-use Non-lease Regarding the comparatives, leases where the lessor retains substantially all the risks and rewards of ownership are classified as operating leases. Operating lease rentals are charged to the Consolidated Income Statement on a straight-line basis over the lease term.
Inventories	Inventories – Note 18 Inventories are stated at the lower of cost and net realisable value. Cost is based on the first-in/first-out first-in/first-out work-in-progress, Net realisable value is the estimated proceeds of sale less all further costs to completion, and less all costs to be incurred in marketing, selling and distribution. Estimates of net realisable value are based on the most reliable evidence available at the time the estimates are made, taking into consideration fluctuations of price or cost directly relating to events occurring after the end of the period, the likelihood of short-term changes in buyer preferences, product obsolescence or perishability (all of which are generally low given the nature of the Group’s products) and the purpose for which the inventory is held. Materials and other supplies held for use in the production of inventories are not written down below cost if the finished goods, in which they will be incorporated, are expected to be sold at or above cost.
Cash and cash equivalents	Cash and cash equivalents – Note 25 Cash and cash equivalents comprise cash balances held for the purpose of meeting short-term cash commitments and investments which are readily convertible to a known amount of cash and are subject to an insignificant risk of change in value. Bank overdrafts are included within current interest-bearing loans and borrowings in the Consolidated Balance Sheet. Where the overdrafts are repayable on demand and form an integral part of cash management, they are netted against cash and cash equivalents for the purposes of the Consolidated Statement of Cash Flows.
Interest-bearing loans and borrowings	Interest-bearing loans and borrowings – Note 26 All loans and borrowings are initially recorded at the fair value of the consideration received net of directly attributable transaction costs. Subsequent to initial recognition, current and non-current Gains and losses are recognised in the Consolidated Income Statement through amortisation on the basis of the period of the loans and borrowings. Borrowing costs arising on financial instruments are recognised as an expense in the period in which they are incurred (unless capitalised as part of the cost of property, plant and equipment).
Derivative financial instruments and hedging practices	Derivative financial instruments and hedging practices – Note 27 In order to manage interest rate, foreign currency and commodity risks and to realise the desired currency profile of borrowings, the Group employs derivative financial instruments (principally interest rate swaps, currency swaps and forward foreign exchange contracts). Derivative financial instruments are recognised initially at fair value on the date on which a derivative contract is entered into and are subsequently remeasured at fair value. The carrying value of derivatives is fair value based on discounted future cash flows and adjusted for counterparty risk. Future floating rate cash flows are estimated based on future interest rates (from observable yield curves at the end of the reporting period). Fixed and floating rate cash flows are discounted at future interest rates and translated at period-end At the inception of a derivative transaction, the Group documents the relationship between the hedged item and the hedging instrument together with its risk management objective and the strategy underlying the proposed transaction. The Group also documents its assessment, both at the inception of the hedging relationship and subsequently on an ongoing basis, of the effectiveness of the hedging instrument in offsetting movements in the fair values or cash flows of the hedged items. Where derivatives do not fulfil the criteria for hedge accounting, changes in fair values are reported in the Consolidated Income Statement and Consolidated Balance Sheet. Fair value and cash flow hedges The Group uses fair value hedges and cash flow hedges in its treasury activities. For the purposes of hedge accounting, hedges are classified either as fair value hedges (which entail hedging the exposure to movements in the fair value of a recognised asset or liability or an unrecognised firm commitment that could affect profit or loss) or cash flow hedges (which hedge exposure to fluctuations in future cash flows derived from a particular risk associated with a recognised asset or liability, or a highly probable forecast transaction that could affect profit or loss). Where the conditions for hedge accounting are satisfied and the hedging instrument concerned is classified as a fair value hedge, any gain or loss stemming from the remeasurement of the hedging instrument to fair value is reported in the Consolidated Income Statement. In addition, any gain or loss on the hedged item which is attributable to the hedged risk is adjusted against the carrying amount of the hedged item and reflected in the Consolidated Income Statement. Where the adjustment is to the carrying amount of a hedged interest-bearing financial instrument, the adjustment is amortised to the Consolidated Income Statement with the objective of achieving full amortisation by maturity. Where a derivative financial instrument is designated as a hedge of the variability in cash flows of a recognised asset or liability or a highly probable forecast transaction that could affect profit or loss, the effective part of any gain or loss on the derivative financial instrument is recognised as other comprehensive income, net of the income tax effect, with the ineffective portion being reported in the Consolidated Income Statement. The associated gains or losses that had previously been recognised as other comprehensive income are transferred to the Consolidated Income Statement contemporaneously with the materialisation of the hedged transaction. Any gain or loss arising in respect of changes in the time value of the derivative financial instrument is excluded from the measurement of hedge effectiveness and is recognised immediately in the Consolidated Income Statement. Hedge accounting is discontinued when the hedging instrument expires or is sold, terminated or exercised, or no longer qualifies for hedge accounting. At that point in time, any cumulative gain or loss on the hedging instrument recognised as other comprehensive income remains there until the forecast transaction occurs. If a hedged transaction is no longer anticipated to occur, the net cumulative gain or loss previously recognised as other comprehensive income is transferred to the Consolidated Income Statement in the period. Net investment hedges Where foreign currency borrowings provide a hedge against a net investment in a foreign operation, and the hedge is deemed to be effective, foreign exchange differences are taken directly to a foreign currency translation reserve. The ineffective portion of any gain or loss on the hedging instrument is recognised immediately in the Consolidated Income Statement. Cumulative gains and losses remain in equity until disposal of the net investment in the foreign operation at which point the related differences are transferred to the Consolidated Income Statement as part of the overall gain or loss on sale.
Share capital and dividends	Share capital and dividends – Notes 31 and 13 Treasury Shares and own shares Ordinary Shares acquired by the Parent Company or purchased by the Employee Benefit Trust on behalf of the Parent Company under the terms of the Performance Share Plans and the Restricted Share Plan are deducted from equity and presented on the face of the Consolidated Balance Sheet. No gain or loss is recognised in profit or loss on the purchase, sale, issue or cancellation of the Parent Company’s Ordinary Shares. Dividends Dividends on Ordinary Shares are recognised as a liability in the Consolidated Financial Statements in the period in which they are declared by the Parent Company.
Foreign currency translation	Foreign currency translation Items included in the financial statements of each of the Group’s entities are measured using the currency of the primary economic environment in which the entity operates (the functional currency). The Consolidated Financial Statements are presented in euro, which is the presentation currency of the Group and the functional currency of the Parent Company. Transactions in foreign currencies are recorded at the rate ruling at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are retranslated at the rate of exchange ruling at the balance sheet date. All currency translation differences are taken to the Consolidated Income Statement with the exception of all monetary items that provide an effective hedge for a net investment in a foreign operation. These are recognised in other comprehensive income until the disposal of the net investment, at which time they are recognised in the Consolidated Income Statement. Results and cash flows of subsidiaries, joint ventures and associates with non-euro non-euro The principal exchange rates used for the translation of results, cash flows and balance sheets into euro were as follows: Average Year-end euro 1 = 2019 2018 2017 2019 2018 Brazilian Real 4.4134 4.3085 3.6054 4.5157 4.4440 Canadian Dollar 1.4855 1.5294 1.4647 1.4598 1.5605 Chinese Renminbi 7.7355 7.8081 7.6290 7.8205 7.8751 Hungarian Forint 325.2967 318.8897 309.1933 330.5300 320.9800 Indian Rupee 78.8361 80.7332 73.5324 80.1870 79.7298 Philippine Peso 57.9851 62.2101 56.9734 56.9000 60.1130 Polish Zloty 4.2976 4.2615 4.2570 4.2568 4.3014 Pound Sterling 0.8778 0.8847 0.8767 0.8508 0.8945 Romanian Leu 4.7453 4.6540 4.5688 4.7830 4.6635 Serbian Dinar 117.8377 118.2302 121.3232 117.8237 118.3157 Swiss Franc 1.1124 1.1550 1.1117 1.0854 1.1269 Ukrainian Hryvnia 28.8881 32.0987 30.0341 26.7377 31.6900 US Dollar 1.1195 1.1810 1.1297 1.1234 1.1450

Summary of Interest Rate Risk	The following table demonstrates the impact on profit before tax and total equity of a range of possible changes in the interest rates applicable to net floating rate borrowings, with all other variables held constant. These impacts are calculated based on the closing balance sheet for the relevant period and assume all floating interest rates and interest curves change by the same amount. For profit before tax, the impact shown is the impact on closing balance sheet floating rate net debt for a full year while for total equity the impact shown is the impact on the value of financial instruments.

Due to the extended timeframe associated with many of the insurances, a significant proportion of the total provision is subject to periodic actuarial valuation. The projected cash flows underlying the discounting process are established through the application of actuarial triangulations, which are extrapolated from historical claims experience. The triangulations applied in the discounting process indicate that the Group’s insurance provisions have an average life of five years (2018: five years). (ii) This provision comprises obligations governing site remediation, restoration and environmental works to be incurred in compliance with either local or national environmental regulations together with constructive obligations stemming from established best practice.

(ii) The Income Shares, which represent 5.86% of the total issued share capital, were created on 29 August 1988 for the express purpose of giving shareholders the choice of receiving dividends on either their Ordinary Shares or on their Income Shares (by notice of election to the Company). The Income Shares carried a different tax credit to the Ordinary Shares. The creation of the Income Shares was achieved by the allotment of fully paid Income Shares to each shareholder equal to his/her holding of Ordinary Shares but the shareholder is not entitled to an Income Share certificate, as a certificate for Ordinary Shares is deemed to include an equal number of Income Shares and a shareholder may only sell, transfer or transmit Income Shares with an equivalent number of Ordinary Shares. Income Shares carry no voting rights. Due to changes in Irish tax legislation since the creation of the Income Shares, dividends on the Company’s shares no longer carry a tax credit. As elections made by shareholders to receive dividends on their holding of Income Shares were no longer relevant, the Articles of Association were amended on 8 May 2002 to cancel such elections. (iii) During 2019 43,750,000 Ordinary Shares (including Income Shares) were cancelled. The amount paid to repurchase these shares was initially recognised in Treasury Shares/own shares and was transferred to retained income on cancellation.

[1]	On 31 December, CRH completed the sale of the Group’s 50% stake in its joint venture in India, My Home Industries Limited (“MHIL”) for deferred proceeds of €0.3 billion which will be received in several agreed tranches. For the purposes of compliance with Indian law requirements, CRH is obliged to retain a minority shareholding and associated minority board representation in MHIL both of which will further reduce as the tranches are completed. The Group no longer has any rights to share in the profit/loss of MHIL or to receive any dividends. CRH has determined that MHIL has ceased to be a joint venture or an associate as the Group is no longer exposed to variability of returns from the performance of MHIL and does not have significant influence (as defined under IAS 28 Interests in Associates and Joint Ventures) over MHIL. With the other partners acting in concert to exercise control, CRH effectively retains only protective voting rights in defined limited circumstances. Accordingly, the Group has discontinued the use of the equity method of accounting for its interest in MHIL from 31 December 2019. The fair value of the retained interest in MHIL is recorded as a financial asset within Other Receivables (see note 21) as it represents a contractual right to receive cash
[2]	In 2018, as part of the divestment of our DIY business in Belgium and the Netherlands (see note 16 and note 17 for further details) we acquired an equity stake of 22.78% in, and advanced a loan of €50 million to the purchaser, Intergamma, which was repaid in 2019.

[1]	The amortisation charge for the year includes €X million (2018: €2 million; 2017: €14 million) in respect of discontinued operations, which primarily relates to customer-related intangible assets.
[2]	In July 2018, the Group divested of its DIY business in the Netherlands and Belgium, together with certain related property assets, which formed part of the former Europe Distribution segment for total consideration of €0.5 billion. The decision to divest resulted in the recognition of an impairment charge of €20 million. The recoverable amount, at the date of impairment, was based on fair value less costs of disposal. The fair value was determined using Level 2 inputs in accordance with the fair value hierarchy, as a market price was agreed and paid.
[3]	The customer-related intangible assets relate predominantly to non-contractual customer relationships.

[1]	This provision comprises obligations governing site remediation, restoration and environmental works to be incurred in compliance with either local or national environmental regulations together with constructive obligations stemming from established best practice. Whilst a significant element of the total provision will reverse in the medium-term (two to ten years), those legal and constructive obligations applicable to long-lived assets (principally mineral-bearing land) will unwind over a 30-year timeframe. In discounting the related obligations, expected future cash outflows have been determined with due regard to extraction status and anticipated remaining life.
[2]	This provision relates to obligations arising under the self-insurance components of the Group’s insurance arrangements which comprise employers’ liability (workers’ compensation in the US), public and products liability (general liability in the US), automobile liability, property damage, business interruption and various other insurances; a substantial proportion of the total provision pertains to claims which are classified as “incurred but not reported”. Due to the extended timeframe associated with many of the insurances, a significant proportion of the total provision is subject to periodic actuarial valuation. The projected cash flows underlying the discounting process are established through the application of actuarial triangulations, which are extrapolated from historical claims experience. The triangulations applied in the discounting process indicate that the Group’s insurance provisions have an average life of five years (2018: five years).
[3]	These provisions relate to irrevocable commitments under various rationalisation and redundancy programmes, none of which are individually material to the Group. In 2019, €29 million (2018: €30 million; 2017: €32 million) was provided in respect of rationalisation and redundancy activities as a consequence of undertaking various cost reduction initiatives across all operations. These initiatives included removing excess capacity from manufacturing and distribution networks and scaling operations to match market supply; back office rationalisation; and the consolidation of certain regional support functions into central and more coordinated hubs. The Group expects that these provisions will primarily be utilised within one to two years of the balance sheet date (2018: one to two years).
[4]	Other provisions primarily relate to legal claims, onerous contracts, guarantees and warranties and employee related provisions. The Group expects the majority of these provisions will be utilised within two to five years of the balance sheet date (2018: two to five years); however due to the nature of the legal provisions there is a level of uncertainty in the timing of settlement as the Group generally cannot determine the extent and duration of the legal process.

[1]	The Ordinary Shares represent 93.71% of the total issued share capital.
[2]	The Income Shares, which represent 5.86% of the total issued share capital, were created on 29 August 1988 for the express purpose of giving shareholders the choice of receiving dividends on either their Ordinary Shares or on their Income Shares (by notice of election to the Company). The Income Shares carried a different tax credit to the Ordinary Shares. The creation of the Income Shares was achieved by the allotment of fully paid Income Shares to each shareholder equal to his/her holding of Ordinary Shares but the shareholder is not entitled to an Income Share certificate, as a certificate for Ordinary Shares is deemed to include an equal number of Income Shares and a shareholder may only sell, transfer or transmit Income Shares with an equivalent number of Ordinary Shares. Income Shares carry no voting rights. Due to changes in Irish tax legislation since the creation of the Income Shares, dividends on the Company’s shares no longer carry a tax credit. As elections made by shareholders to receive dividends on their holding of Income Shares were no longer relevant, the Articles of Association were amended on 8 May 2002 to cancel such elections.
[3]	During 2019 43,750,000 Ordinary Shares (including Income Shares) were cancelled. The amount paid to repurchase these shares was initially recognised in Treasury Shares/own shares and was transferred to retained income on cancellation.
