Seasonality	Note 4: Seasonality The Company’s revenues and operating profit on a consolidated basis do not tend to be significantly impacted by seasonality as it records a large portion of its revenues ratably over the contract term and its costs are generally incurred evenly throughout the year. However, the Company’s revenues from quarter to consecutive quarter can be impacted by seasonality, particularly in the Company’s Tax & Accounting business, where revenues tend to be concentrated in the first and fourth quarters.

Business Description and Basis of Preparation

Note 1: Business Description and Basis of Preparation

General business description

Thomson Reuters Corporation (the “Company” or “Thomson Reuters”) is an Ontario, Canada corporation with common shares listed on the Toronto Stock Exchange (“TSX”) and the New York Stock Exchange (“NYSE”) and Series II preference shares listed on the TSX. The Company serves professionals across legal, tax, accounting, compliance, government, and media. Its products combine highly specialized software and insights to empower professionals with the data, intelligence, and solutions needed to make informed decisions, and to help institutions in their pursuit of justice, truth and transparency. Reuters, part of Thomson Reuters, is a world leading provider of trusted journalism

and

news.

These unaudited interim consolidated financial statements (“interim financial statements”) were approved by the Audit Committee of the Board of Directors of the Company on July 31, 2024.

Basis of preparation

The interim financial statements were prepared using the same accounting policies and methods as those used in the Company’s consolidated financial statements for the year ended December 31, 2023. The interim financial statements comply with International Accounting Standard 34,

Interim Financial Reporting

(“IAS 34”). Accordingly, certain information and footnote disclosure normally included in annual financial statements prepared in accordance with International Financial Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board (“IASB”), have been omitted or condensed.

The preparation of financial statements in accordance with IAS 34 requires the use of certain critical accounting estimates. It also requires management to exercise judgment in applying the Company’s accounting policies. The areas involving more judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements have been disclosed in note 2 of the consolidated financial statements for the year ended December 31, 2023.

The Company continues to operate in an uncertain macroeconomic environment, reflecting ongoing geopolitical risk, uneven economic growth, and an evolving interest rate and inflationary backdrop, among other factors. While the Company is closely monitoring these conditions to assess potential impacts on its businesses, some of management’s estimates and judgments may be more variable and may change materially in the future due to the significant uncertainty created by these circumstances.

The accompanying interim financial statements include all adjustments, composed of normal recurring adjustments, considered necessary by management to fairly state the Company’s results of operations, financial position and cash flows. The operating results for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. These interim financial statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2023, which are included in the Company’s 2023 annual report.

References to “$” are to U.S. dollars, references to “C$” are to Canadian dollars, references to “£” are to British pounds sterling and references to SEK are to Swedish Krona.

Recent accounting pronouncements

IAS 21,

The Effect of Changes in Foreign Exchange Rates

In August 2023, the IASB issued amendments to IAS 21, which provide guidance on the determination of an exchange rate to translate transactions and financial statements denominated or presented in a currency that is not exchangeable into another currency. The amendments are effective for reporting periods beginning January 1, 2025. The Company is assessing the impact of these amendments on its financial statements.

IFRS 18,

Presentation and Disclosure in Financial Statements

In April 2024, the IASB issued IFRS 18, which will replace IAS 1,

Presentation of Financial Statements,

and is effective for reporting periods beginning January 1, 2027. IFRS 18 will change the presentation of the Company’s financial statements and add new disclosure requirements. Specifically, the new standard requires:

●

The consolidated income statement to be structured according to operating, investing and financing categories, and include additional subtotals for “Operating Profit” and “Profit Before Financing and Income Taxes”;

●

Management-defined performance measurements (“MPM’s”), which represent certain of the Company’s

non-IFRS

measures, to be identified, defined, and have an explanation why each one is useful. Each MPM must be reconciled to the most directly comparable IFRS subtotal. All disclosures related to MPM’s must be disclosed in a single footnote within the consolidated financial statements; and

●

The application of enhanced guidance related to the grouping of financial information associated with amounts presented within the financial statements, otherwise known as aggregation or disaggregation.

The Company is assessing the impact of IFRS 18 on its disclosures.

Amendments to IAS 7

, Statement of Cash Flows

The amendments were issued to align the presentation of the statement of cash flows, as prepared under the indirect method, to the changes prescribed to the income statement under IFRS 18.

Both IFRS 18 and the amendments to IAS 7 are disclosure related and do not impact the Company’s results of operations, financial condition, or cash flows.

Amendments to IFRS 9 and IFRS 7

, Amendments to the Classification and Measurement of Financial Instruments

In May 2024, the IASB issued amendments to IFRS 9,

Financial Instruments

and

IFRS 7,

Financial Instruments: Disclosures

. The amendments introduce:

●

An election permitting derecognition of financial liabilities that are settled through an electronic payment system before the actual settlement date, if certain conditions are met; and

●

Expanded disclosures for (a) investments in equity instruments and (b) financial liabilities that have features unrelated to basic lending risks, such as achieving sustainability targets, that could affect the cash flows of those liabilities.

The amendments are effective for reporting periods beginning on January 1, 2026. The Company is assessing the impact of the amendments on its financial statements and its disclosures.

Other pronouncements issued by the IASB and International Financial Reporting Interpretations Committee (“IFRIC”) are not applicable or consequential to the Company.

Investments accounted for using equity method [abstract]

Equity Method Investments

Note 8: Equity Method Investments

Equity method investments in the consolidated statement of financial position were comprised of the following:


	June 30,		December 31,

	2024		2023
YPL (1)		30		1,798
Other equity method investments		200		232
Total equity method investments		230		2,030

(1)	The balance as of June 30, 2024 represents undistributed cash from sale of remaining LSEG shares.

In May 2024, LSEG agreed to amend the terms of the contractual

lock-up

provisions previously agreed between LSEG and the Blackstone consortium/Thomson Reuters entities that hold the LSEG shares. The amended terms allowed the Company to sell its remaining LSEG shares that it indirectly owned through its direct investment in York Parent Limited and its subsidiaries (“YPL”) in the second quarter of 2024. YPL is an entity jointly owned by the Company and Blackstone’s consortium (comprised of The Blackstone Group and its subsidiaries, and private equity funds affiliated with Blackstone).

The investment in LSEG was subject to equity accounting because the LSEG shares were held through YPL, over which the Company had significant influence. As YPL owned only the financial investment in LSEG shares, which the parties intended to sell over time, and was not involved in operating LSEG, the investment in LSEG shares held by YPL was accounted for at fair value, based on the share price of LSEG. As the investment in LSEG was denominated in British pounds sterling, the Company entered into a series of foreign exchange contracts to mitigate currency risk on its investment. The Company settled its remaining foreign exchange contracts in conjunction with the May 2024 LSEG share sale (see note 11).

In the three months ended June 30, 2024, the Company sold 5.9 million shares of LSEG and received $0.6 billion of gross proceeds, net of a $33 million payment to settle its remaining foreign exchange contracts. In the six months ended June 30, 2024, the Company sold 16.0 million shares of LSEG including 2.6 million that were subject to call options, for $1.9 billion of gross proceeds, which included $24 million received from the settlement of foreign exchange contracts and $58 million from shares sold in 2023 that settled in 2024. Of this amount, $1.8 billion was received in the form of dividends from YPL.

In the three months ended June 30, 2023, the Company sold 15.6 million shares of LSEG that it indirectly owned for gross proceeds of $1.6 billion, which included $28 million from the settlement of foreign exchange contracts. In the six months ended June 30, 2023, the Company sold 40.1 million shares of LSEG that it indirectly owned for gross proceeds of $3.9 billion, which included $124 million from the settlement of foreign exchange contracts. Of this amount, $3.8 billion was received in the form of dividends from YPL.

These amounts were recorded as a reduction of the Company’s investment (except for the amounts related to the settlement of the foreign exchange contracts) and presented as investing activities in the consolidated statement of cash flow.

The Company’s share of

post-tax

earnings (losses) in equity method investments as reported in the consolidated income statement is comprised of the following:


	Three months ended June 30,				Six months ended June 30,

	2024		2023		2024		2023

Earnings Per Share

Note 10: Earnings Per Share

Basic earnings per share was calculated by dividing earnings attributable to common shareholders less dividends declared on preference shares by the sum of the weighted-average number of common shares outstanding and vested deferred share units (“DSUs”) outstanding during the period. DSUs represent common shares that certain employees have elected to receive in the future upon vesting of share-based compensation awards or in lieu of cash compensation.

Diluted earnings per share was calculated using the denominator of the basic calculation described above adjusted to include the potentially dilutive effect of outstanding stock options and time-based restricted share units (“TRSUs”).

Earnings used in determining consolidated earnings per share and earnings per share from continuing operations are as follows:

The excess of the purchase price over the net assets acquired was recorded as goodwill and reflects synergies and the value of the acquired workforce. Relative to the acquisitions completed in the six months ended June 30, 2024, the majority of goodwill is not expected to be deductible for tax purpose

. For the acquisition completed in the six months ended June 30, 2023, the majority of goodwill is expected to be deductible for tax purposes.

Purchase price allocation

Purchase price allocations related to certain acquisitions may be subject to adjustment pending completion

final valuations.

In the three months ended June 30, 2024, the Company recorded measurement period adjustments for its Pagero acquisition, which primarily included a decrease to computer software and other identifiable intangible assets of $14 million and $7 million, respectively, and an increase to goodwill of $18 million.

Pagero

In January 2024, the Company acquired a controlling interest in Pagero through a public tender offer. Subsequently, the Company purchased the remaining interests from the

non-controlling

shareholders. As of June 30, 2024, the Company owns 100% of Pagero.

The

non-controlling

interest was measured at fair value, based on the tender offer price of SEK 50 per share, on the date of acquisition and recorded as part of equity. After the date of acquisition, the

non-controlling

interest was adjusted for its proportionate share of changes in equity. After the Company gained control of Pagero, purchases of the remaining shares from the

non-controlling

interests reduced equity and were presented in financing activities within the consolidated statement of cash flow.

Other

The revenues and operating profit of acquired businesses were not material to the Company’s results of operations.

Contingencies	Jun. 30, 2024
Text block [abstract]
Contingencies	Note 18: Contingencies Lawsuits and legal claims The Company is engaged in various legal proceedings, claims, audits and investigations that have arisen in the ordinary course of business. These matters include, but are not limited to, employment matters, commercial matters, privacy and data protection matters, defamation matters and intellectual property infringement matters. The outcome of all the matters against the Company is subject to future resolution, including uncertainties of litigation. Litigation outcomes are difficult to predict with certainty due to various factors, including but not limited to: the preliminary nature of some claims; uncertain damage theories and demands; an incomplete factual record; uncertainty concerning legal theories and procedures and their resolution by the courts, at both trial and appellate levels; and the unpredictable nature of opposing parties. Based on information currently known to the Company and after consultation with outside legal counsel, management believes that the ultimate resolution of any such matters, individually or in the aggregate, will not have a material adverse impact on the Company’s financial condition taken as a whole. Uncertain tax positions The Company is subject to taxation in numerous jurisdictions and is routinely under audit by many different taxing authorities in the ordinary course of business. There are many transactions and calculations during the course of business for which the ultimate tax determination is uncertain, as taxing authorities may challenge some of the Company’s positions and propose adjustments or changes to its tax filings. As a result, the Company maintains provisions for uncertain tax positions that it believes appropriately reflect its risk. These provisions are made using the Company’s best estimates of the amount expected to be paid based on a qualitative assessment of all relevant factors. When appropriate, the Company performs an expected value calculation to determine its provisions. The Company reviews the adequacy of these provisions at the end of each reporting period and adjusts them based on changing facts and circumstances. Due to the uncertainty associated with tax audits, it is possible that at some future date, liabilities resulting from such audits or related litigation could vary significantly from the Company’s provisions. However, based on currently enacted legislation, information currently known by the Company and after consultation with outside tax advisors, management believes that the ultimate resolution of any such matters, individually or in the aggregate, will not have a material adverse impact on the Company’s financial condition taken as a whole. Prior to December 31, 2023, the Company paid $430 million of tax as required under notices of assessment issued by the U.K. tax authority, HM Revenue & Customs (“HMRC”), under the Diverted Profits Tax (“DPT”) regime that collectively related to the 2015, 2016, 2017 and 2018 taxation years of certain of its current and former U.K. affiliates. The Company does not believe these current and former U.K. affiliates fall within the scope of the DPT regime. Because the Company believes its position is supported by the weight of law, it intends to vigorously defend its position and will continue contesting these assessments through all available administrative and judicial remedies. As the assessments largely relate to businesses that the Company has sold, the majority are subject to indemnity arrangements under which the Company has been required to pay additional taxes to HMRC or the indemnity counterparty. The Company does not believe that the resolution of these matters will have a material adverse effect on its financial condition taken as a whole. Payments made by the Company are not a reflection of its view on the merits of the case. As the Company expects to receive refunds of substantially all of the aggregate of amounts paid pursuant to these notices of assessment, it expects to continue recording substantially all of these payments as non-current receivables from HMRC or the indemnity counterparty, in its financial statements. Guarantees The Company has an investment in 3XSQ Associates, an entity jointly owned by a subsidiary of the Company and Rudin Times Square Associates LLC (“Rudin”), that owns and operates the 3 Times Square office building (“the building”) in New York, New York. In June 2022, 3XSQ Associates obtained a $415 million, 3-year term loan facility to refinance existing debt, fund the building’s redevelopment, and cover interest and operating costs during the redevelopment period. The building is pledged as loan collateral. Thomson Reuters and Rudin each guarantee 50% of (i) certain principal loan amounts and (ii) interest and operating costs. Thomson Reuters and Rudin also jointly and severally guarantee (i) completion of commenced works and (ii) lender losses arising from disallowed acts, environmental or otherwise. To minimize economic exposure to 50% for the joint and several obligations, Thomson Reuters and a parent entity of Rudin entered into a cross-indemnification arrangement. The Company believes the value of the building is expected to be sufficient to cover obligations that could arise from the guarantees. The guarantees do not impact the Company’s ability to borrow funds under its $2.0 billion syndicated credit facility or the related covenant calculation.

Text block [abstract]
Taxation	Note 9: Taxation Tax benefit was $402 million and $335 million for the three months and six months ended June 30, 2024, respectively, due to a $468 million benefit from the recognition of a deferred tax asset relating to new tax legislation enacted in Canada. The new legislation reduced the Company’s ability to deduct interest expense against its Canadian taxable income, thereby increasing Canadian taxable profits such that the Company now expects to utilize tax loss carryforwards and other tax attributes, which it had not previously recognized as a deferred tax asset. In January 2024, the Company began recording tax expense associated with the “Pillar Two model rules” as published by the Organization for Economic Cooperation and Development and enacted by key jurisdictions in which the Company operates. These rules are designed to ensure large multinational enterprises within the scope of the rules pay a minimum level of tax in each jurisdiction where they operate. In general, the “Pillar Two model rules” apply a system of top-up taxes to bring the enterprise’s effective tax rate in each jurisdiction to a minimum of 15%. In the three and six months ended June 30, 2024, income tax benefit included $5 million and $7 million, respectively, of top-up tax expense which was attributable to the Company’s earnings in Switzerland. Tax expense was $219 million for the three months ended June 30, 2023 and included $97 million of tax expense related to the Company’s earnings in equity method investments. Tax expense was $415 million in the six months ended June 30, 2023 and included $233 million of tax expense related to the Company’s earnings in equity method investments. Both periods in 2023 included $78 million of expense related to the sale of a majority stake in Elite, as well as $24 million of benefits from the settlement of a tax audit. Additionally, the tax benefit or expense in each period reflected the mix of taxing jurisdictions in which pre-tax profits and losses were recognized. Because the geographical mix of pre-tax profits and losses in interim periods may be different from that for the full year, tax expense or benefit in interim periods is not necessarily indicative of the tax benefit or expense for the full year.

Capital

Note 15: Capital

Share repurchases – Normal Course Issuer Bid (“NCIB”)

The Company buys back shares (and subsequently cancels them) from time to time as part of its capital strategy. On November 1, 2023, the Company announced that it planned to repurchase up to $1.0 billion of its common shares. In May 2024, the Company completed this plan. Share repurchases are typically executed under a NCIB. Shares were repurchased for the buyback program under a renewed NCIB, which was approved by the TSX and effective on November 1, 2023. Under the renewed NCIB, up to 10 million common shares may be repurchased between November 3, 2023 and November 2, 2024. The Company may repurchase common shares in open market transactions on the TSX, the NYSE and/or other exchanges and alternative trading systems, if eligible, or by such other means as may be permitted by the TSX and/or NYSE or under applicable law, including private agreement purchases or share purchase program agreement purchases if the Company receives, if applicable, an issuer bid exemption order in the future from applicable securities regulatory authorities in Canada for such purchases. The price that the Company will pay for common shares in open market transactions will be the market price at the time of purchase or such other price as may be permitted by the TSX.

Details of share repurchases were as follows:


	Three months ended June 30,				Six months ended June 30,
	2024		2023		2024		2023

Share repurchases (millions of U.S. dollars)		287		–		639		718

Shares repurchased (number in millions)		1.8		–		4.1		6.0

Share repurchases - average price per share in U.S. dollars	$	161.32		–	$	156.92	$	120.10

Decisions regarding any future repurchases will depend on certain factors, such as market conditions, share price, and other opportunities to invest capital for growth. The Company may elect to suspend or discontinue share repurchases at any time, in accordance with applicable laws. From time to time when the Company does not possess material nonpublic information about itself or its securities, it may enter into a

pre-defined

plan with its broker to allow for the repurchase of shares at times when the Company ordinarily would not be active in the market due to its own internal trading blackout periods, insider trading rules or otherwise. Any such plans entered into with the Company’s broker will be adopted in accordance with applicable Canadian securities laws and the requirements of Rule

10b5-1

under the U.S. Securities Exchange Act of 1934, as amended. The Company entered into such a plan with its broker on December 28, 2023. As a result, the Company recorded a $400 million liability in “Other financial liabilities” within current liabilities as of December 31, 2023 with a corresponding amount recorded in equity in the consolidated statement of financial position. This liability was settled through the purchase of shares in 2024.

Dividends

Dividends on common shares are declared in U.S. dollars. In the consolidated statement of cash flow, dividends paid on common shares are shown net of amounts reinvested in the Company under its dividend reinvestment plan.

Based on the Company’s current credit ratings, the cost of borrowing under the facility is priced at the Term Secured Overnight Financing Rate (“SOFR”)/Euro Interbank Offered Rate (“EURiBOR”)/Simple Sterling Overnight Index Average (“SONIA”) plus 102.5 basis points. The Company has the option to request an increase, subject to approval by applicable lenders, in the lenders’ commitments in an aggregate amount of $600 million for a maximum credit facility commitment of $2.6 billion.

The Company guarantees borrowings by its subsidiaries under the credit facility. The Company must also maintain a ratio of net debt as defined in the credit agreement (total debt after swaps less cash and cash equivalents) as of the last day of each fiscal quarter to EBITDA as defined in the credit agreement (earnings before interest, income taxes, depreciation and amortization and other modifications described in the credit agreement) for the last four quarters ended of not more than 4.5:1. If the Company were to complete an acquisition with a purchase price of over $500 million, the Company may elect, subject to notification, to temporarily increase the ratio of net debt to EBITDA to 5.0:1 at the end of the quarter within which the transaction closed and for each of the three immediately following fiscal quarters. At the end of that period, the ratio would revert to 4.5:1. As of June 30, 2024, the Company complied with this covenant as its ratio of net debt to EBITDA, as calculated under the terms of its syndicated credit facility, was 0.5:1.

Foreign exchange contracts

The Company previously entered into foreign exchange contracts that were intended to reduce foreign currency risk related to a portion of its former indirect investment in LSEG, which was denominated in British pounds sterling. These instruments were not related to changes in the LSEG share price. In May 2024, the Company settled its remaining foreign exchange contracts in conjunction with the sale of its remaining shares in LSEG (see note 8).

In the three months ended June 30, 2024, the Company settled foreign exchange contracts with a notional amount of £300 million ($349 million) for net payments of $33 million in conjunction with the sale of 5.9 million LSEG shares. In the six months ended June 30, 2024, the Company settled foreign exchange contracts with a notional amount of £1.2 billion ($1.6 billion) for net proceeds of $24 million in conjunction with the sale of 16.0 million LSEG shares.

In the three months ended June 30, 2023, the Company settled foreign exchange contracts with a notional amount of £1.2 billion ($1.6 billion) for net proceeds of $28 million in conjunction with the sale of 15.3 million of LSEG shares. In the six months ended June 30, 2023, the Company settled foreign exchange contracts with a notional amount £2.2 billion ($2.9 billion) for net proceeds of $124 million in conjunction with the sale of 28.9 million LSEG shares.

In the three and six months ended June 30, 2024, losses of $3 million and $2 million (2023 – losses of $66 million and $135 million), respectively, were reported within “Other finance income (costs)” in the consolidated income statement (see note 7) with respect to these foreign exchange contracts due to fluctuations in the U.S. dollar – British pounds sterling exchange rate.

Fair Value

The fair values of cash and cash equivalents, trade and other receivables, trade payables and accruals approximate their carrying amounts because of the short-term maturity of these instruments. The fair value of long-term debt and related derivative instruments is set forth below.

Debt and Related Derivative Instruments

Carrying Amounts

Amounts recorded in the consolidated statement of financial position are referred to as “carrying amounts”. The carrying amounts of primary debt are reflected in “Current indebtedness” or “Long-term indebtedness” and the carrying amounts of derivative instruments are included in “Other financial assets” and “Other financial liabilities”, current or

non-current,

in the consolidated statement of financial position, as appropriate.

Fair Value

The fair value of debt is estimated based on either quoted market prices for similar issues or current rates offered to the Company for debt of the same maturity. The fair value of interest rate swaps is estimated based upon discounted cash flows using applicable current market rates and considering

non-performance

risk.

The following is a summary of debt and related derivative instruments that hedge the cash flows of debt:

Fair value estimation

The following fair value measurement hierarchy is used for financial instruments that are measured in the consolidated statement of financial position at fair value:

●

Level 1 - quoted prices (unadjusted) in active markets for identical assets or liabilities;

●

Level 2 - inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly (that is, as prices) or indirectly (that is, derived from prices); and

●

Level 3 - inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs).

The levels used to determine fair value measurements for those instruments carried at fair value in the consolidated statement of financial position are as follows:


June 30, 2024				Total

Assets	Level 1	Level 2	Level 3		Balance
Money market accounts	–	1,341	–		1,341
Other receivables (1)	–	–	266		266
Financial assets at fair value through earnings	–	1,341	266		1,607
Financial assets at fair value through other comprehensive income (2)	36	–	81		117
Derivatives used for hedging (3)	–	31	–		31
Total assets	36	1,372	347		1,755
Liabilities
Contingent consideration (4)	–	–	(47)		(47)
Financial liabilities at fair value through earnings	–	–	(47)		(47)
Total liabilities	–	–	(47)		(47)


December 31, 2023				Total

Assets	Level 1	Level 2	Level 3		Balance

Money market accounts	–	906	–		906

Other receivables (1)	–	–	263		263

Foreign exchange contracts (5)	–	58	–		58

Financial assets at fair value through earnings	–	964	263		1,227

Financial assets at fair value through other comprehensive income (2)	33	–	65		98

Financial liabilities at fair value through earnings	–	(32)	(22)		(54)

Total liabilities	–	(32)	(22)		(54)

(1)	Receivables under indemnification arrangement (see note 18).

(2)	Investments in entities over which the Company does not have control, joint control or significant influence.

(3)	Comprised of fixed-to-fixed cross-currency swaps on indebtedness.

(4)	Obligations to pay additional consideration for prior acquisitions, based upon performance measures contractually agreed at the time of purchase, and to purchase shares from minority owners of a subsidiary.

(5)	Related to the management of foreign exchange risk on a portion of the Company’s former indirect investment in LSEG.

The Company recognizes transfers into and out of the fair value measurement hierarchy levels at the end of the reporting period in which the event or change in circumstances that caused the transfer occurred. There were no transfers between hierarchy levels for the six months ended June 30, 2024.

Valuation Techniques

The fair value of financial instruments that are not traded in an active market (for example,

over-the-counter

derivatives) is determined by using valuation techniques. These valuation techniques maximize the use of observable market data where it is available and rely as little as possible on entity specific estimates. If all significant inputs required to fair value an instrument are observable, the instrument is included in level 2. If one or more of the significant inputs is not based on observable market data, the instrument is included in level 3.

Specific valuation techniques used to value financial instruments include:

●

Quoted market prices or dealer quotes for similar instruments;

●

The fair value of cross-currency interest rate swaps and foreign exchange contracts are calculated as the present value of the estimated future cash flows based on observable yield curves;

●

The fair value of other receivables considers estimated future cash flows, current market interest rates and

non-performance

risk; and

●

The fair value of contingent consideration is calculated based on estimates of future revenue performance.
