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 is a major provider of news and business information services to professionals.

Basis of preparation

The unaudited consolidated interim financial statements (“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, 2019. 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, 2019. In March 2020, the World Health Organization characterized a novel strain of the coronavirus, known as

COVID-19,

as a pandemic. The global economy continues to experience substantial disruption due to concerns regarding the spread of

COVID-19,

as well as from the measures intended to mitigate its impact. Refer to note 2 of these interim consolidated financial statements for a description of how

COVID-19

impacted the Company’s critical accounting estimates that were used to prepare the interim financial statements for the three and six months ended June 30, 2020.

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, 2019, which are included in the Company’s 2019 annual report.

Prior-period amounts have been revised to correct certain immaterial misstatements as reflected in the Company’s consolidated financial statements for the year ended December 31, 2019. Refer to the sections below and note 3 of the consolidated financial statements for the year ended December 31, 2019 for additional information.

Additionally, the Company adjusted its prior-period segment amounts to reflect the current presentation. In the first quarter of 2020, in connection with the completion of the Company’s program to reposition its businesses after the separation of Refinitiv, the Company

re-assessed

its methodology for allocating costs to its business segments and adjusted its allocations. The 2019 segment amounts were also adjusted to reflect the transfer of certain revenues primarily from the Corporates segment to the Legal Professionals segment, where they are better aligned. These changes impacted the 2019 financial results of the segments, but did not change the consolidated 2019 financial results. The table below summarizes the changes:

Revision of prior-period financial statements

On October 1, 2018, the Company sold a 55% interest in its Financial & Risk business to private equity funds affiliated with Blackstone. The Company retained a 45% interest in the business, which is now known as Refinitiv. Since October 1, 2018, the Company has included its share of

post-tax

losses from its 45% interest in Refinitiv, an equity method investment, in its net earnings. In the third quarter of 2019, a misstatement was identified that understated the Company’s share of Refinitiv’s

post-tax

losses since the fourth quarter of 2018. The misstatement related to an accounting principle difference for preferred stock issued by Refinitiv to the Blackstone consortium between U.S. GAAP, the basis on which Refinitiv prepares its financial statements, and IFRS, the basis on which Thomson Reuters prepares its financial statements. Specifically, Refinitiv accounts for its preferred stock under U.S. GAAP as equity, but these securities should have been recorded as debt under IFRS. Accordingly, the Company’s share of Refinitiv’s

post-tax

losses under IFRS should have been higher to reflect the associated interest expense. This misstatement did not impact revenues, operating profit, segment measures or cash generated from operating activities.

The Company performed a materiality evaluation in accordance with the Securities and Exchange Commission’s Staff Accounting Bulletin (“SAB”) No. 99,

Materiality

, and SAB No. 108,

Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements

, and concluded that the misstatement was immaterial to its previously issued financial statements. However, as the impact of correcting the cumulative misstatement in the third quarter of 2019 would have been material to net earnings in that quarter, the Company revised its previously issued financial statements. Additionally, in conjunction with this revision, the Company corrected other unrelated misstatements in the applicable prior periods, which were also not material to any of its previously issued financial statements.

The effects of the revision are set forth in the table below:

Critical Accounting Estimates and Judgments

Note 2: Critical Accounting Estimates and Judgments – Impact of

COVID-19

Pandemic

The global economic crisis caused by the

COVID-19

pandemic has created significant uncertainty about the future. As a result, some of the estimates and judgments that management makes in preparing its financial statements may be more variable and may change materially in the future. Management initially assessed its critical accounting estimates and judgments in light of

COVID-19

in conjunction with its interim report for the three months ended March 31, 2020. In the second quarter of 2020, management

re-assessed

these estimates and judgments and made no significant changes. For purposes of its business planning and valuation estimates, the Company continues to assume that the global economy will gradually recover throughout the second half of 2020. The following provides information regarding management’s critical accounting estimates and judgments relative to the global economic crisis caused by

COVID-19.

Allowance for doubtful accounts and sales adjustments

The Company provided additional reserves of $6 million and $15 million in the three months and six months ended June 30, 2020 to reflect that some of its smaller legal and tax customers may not be able to pay for the products and services the Company has provided and, in limited situations, for credits the Company may issue to customers in financial distress. While the Company has offered payment plans to some of its smaller customers who may require more time to pay, very few have elected this option to date.

Computer software

The Company has not experienced, nor does it expect, material changes to product demand and it does not plan to discontinue any products as a result of the crisis that would require impairment or shortened useful lives.

Other identifiable intangible assets and goodwill

At October 1, 2019, the date of the Company’s last impairment test, the estimated fair value less costs of disposal of each cash generating unit (“CGU“), which comprise each of its reportable segments, exceeded their carrying value by over 100%. The Company’s sensitivity analysis demonstrated that no reasonably possible change in its assumptions due to the

COVID-19

pandemic, including higher discount rates and reduction in cash flows, would cause the carrying amounts of any CGU, including the carrying value of the indefinite lived tradenames, to exceed its recoverable amount.

Equity method investments and related warrants

Equity method investments consisted primarily of the Company’s 45% investment in Refinitiv. On August 1, 2019, the Company and private equity funds affiliated with Blackstone agreed to sell Refinitiv to London Stock Exchange Group plc (“LSEG”) (see note 9) for a value that is substantially in excess of the carrying value of the Company’s investment, as measured by the share price of LSEG at June 30, 2020. The proposed transaction, which was approved by LSEG shareholders in November 2019, remains subject to regulatory clearances and other customary closing conditions and is expected to close by the end of 2020 or early in 2021. The Company expects to record a significant gain on the transaction upon closing and therefore concluded that there was no impairment to its investment in Refinitiv at June 30, 2020.

Reflecting the terms of the agreement, the Company valued the related warrants (see note 12) in Refinitiv at June 30, 2020 primarily based on the number of incremental shares in Refinitiv to which the Company is contractually entitled upon closing, the share price of LSEG on June 30, 2020, and management’s assessment that the deal remains highly probable of closing by the end of 2020 or early in 2021.

The Company holds other investments aggregating $0.2 billion in a variety of industries, including real estate, technology and media, which could become impaired in the future due to economic conditions caused by the

COVID-19

pandemic.

Employee future benefits

The assets and obligations for the Company’s most significant benefit plans in the U.S. and the U.K. are remeasured each quarter with an offset to other comprehensive income or loss. For the six months ended June 30, 2020, the Company recorded remeasurement gains of $23 million. There were no funding requirements triggered by changes in the value of assets and liabilities associated with the Company’s material defined benefit plans due to increased market volatility associated with the economic crisis.

Income taxes

Relevant tax reform related to the economic crisis, most notably the impact of the Coronavirus Aid, Relief and Economic Security (“CARES”) Act in the United States, did not have a material impact on the computation of income taxes. The Company concluded that its updated projections relating to

COVID-19

did not impact its ability to realize its deferred tax assets.

Critical judgments in applying accounting policies

Revenue recognition

Management has elevated its focus on collectability in making its revenue recognition judgments while the crisis persists.

Uncertain tax positions

The Company made no changes in its judgments of uncertain tax positions as a result of the

COVID-19

pandemic.

Seasonality

Note 5: 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 a 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 the release of certain tax products, which tend to be concentrated in the fourth quarter and, to a lesser extent, in the first quarter of the year. The Company believes that its revenues in the second quarter of 2020 reflected the lowest level it will report for any of the four quarters in the full year of 2020, due to the impact of

COVID-19.

In 2019, the seasonality of the Company’s operating profit was impacted by significant costs to reposition its business following the sale of a majority interest in Financial & Risk.

Proposed LSEG/Refinitiv Transaction

On August 1, 2019, the Company and private equity funds affiliated with Blackstone agreed to sell Refinitiv to LSEG in an all share transaction for a total enterprise value of approximately $27 billion (as of the announcement date), but LSEG may, at its option, settle up to $2.5 billion of the consideration in cash. The transaction is expected to result in Blackstone’s consortium and Thomson Reuters ultimately holding a combined 37% economic interest in LSEG (of which a 15% economic interest would be attributed to Thomson Reuters) and a combined voting interest in LSEG of less than 30%. The proposed transaction, which was approved by LSEG shareholders in November 2019, remains subject to regulatory clearances and other customary closing conditions. The Company expects the transaction to close by the end of 2020 or early in 2021 and expects to record a significant gain on the transaction upon closing.

Note 10: Taxation

Tax expense was $16 million and $47 million for the three months ended June 30, 2020 and 2019, respectively, and $63 million and $48 million for the six months ended June 30, 2020 and 2019, respectively. The tax 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 tax expense for the full year.

Earnings Per Share

Earnings Per Share

Note 11: 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:



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

	2020		2019		2020		2019
Earnings attributable to common shareholders		126		180		319		284
Less: Dividends declared on preference shares		-		(1)		(1)		(2)
Earnings used in consolidated earnings per share		126		179		318		282
Less: Loss from discontinued operations, net of tax		5		27		3		37
Earnings used in earnings per share from continuing operations		131		206		321		319

The weighted-average number of common shares outstanding, as well as a reconciliation of the weighted-average number of common shares outstanding used in the basic earnings per share computation to the weighted-average number of common shares outstanding used in the diluted earnings per share computation, is presented below:



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

Cash and cash equivalents

Of total cash and cash equivalents, $45 million and $34 million at June 30, 2020 and December 31, 2019, respectively, were held in subsidiaries which have regulatory restrictions, contractual restrictions or operate in countries where exchange controls and other legal restrictions apply and were therefore not available for general use by the Company.

Debt-related activity

The following table provides information regarding notes that the Company issued and repaid in the six months ended June 30, 2020.


MONTH/YEAR	TRANSACTION	PRINCIPAL AMOUNT (IN MILLIONS)
	Notes issued
May 2020	2.239% Notes, due 2025	C$1,400
	Notes repaid
January 2020	3.309% Notes, due 2021	C$550
January 2020	3.95% Notes, due 2021	US$139

The new notes issued in May 2020 were immediately swapped into U.S. dollars and the Company used the $999

illion of net proceeds for general corporate purposes, which included repayment of borrowings under the Company’s credit facility.

In January 2020, the Company repaid notes prior to their scheduled maturity dates

for

$640 million

This amount included early redemption premiums and settlement of cross-currency swaps. The repayments were funded with commercial paper borrowings.

Cross-currency interest rate swaps

The Company uses

fixed-to-fixed

cross-currency interest rate swaps to hedge its currency exposures on indebtedness. These instruments swap Canadian dollar denominated principal and interest payments into U.S. dollars. In connection with the issuance of new Canadian dollar denominated notes in May 2020, the Company entered into cross-currency interest rate swaps. At June 30, 2020, the Company recorded the swaps outstanding in the consolidated statement of financial position at fair value, which was

an asset of $17 million. The swaps were designated as cash flow hedges.

The details of

these

The ineffective portion of the cash flow hedges recognized through earnings was a gain of $7 million, which was recorded in “Other finance (costs) income” in the consolidated income statement

was

reclassified from “Cash flow hedges adjustments to net earnings” in the consolidated statement of comprehensive income

for the three and six months ended June 30, 2020.

Commercial paper

Under its commercial paper program, the Company may issue up to $1.8 billion of notes. In January 2020, the Company issued $630 million of commercial paper, most of which was repaid in February and March 2020. At June 30, 2020, current indebtedness included $120 million of outstanding commercial paper within the consolidated statement of financial position.

Credit facility

The Company has a $1.8 billion syndicated credit facility agreement which matures in December 2024 and may be used to provide liquidity for general corporate purposes (including acquisitions or support for its commercial paper program). There were no outstanding borrowings under the facility at June 30, 2020. The Company borrowed $1.0 billion in the first quarter of 2020, which

repaid in the second quarter of 2020. Based on the Company’s current credit ratings, the cost of borrowing under the facility is priced at LIBOR/EURIBOR plus 112.5 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 $2.4 billion.

In July 2017, the U.K. Financial Conduct Authority, which regulates LIBOR, announced that it intends to phase out LIBOR by the end of 2021. As a result, public and private sector industry initiatives are currently underway to identify an alternative reference rate.

The Company must 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 ratio of net debt to EBITDA would temporarily increase to 5.0:1 for

the following

three quarters a

fter

completion, a

fter

which time the ratio would revert to 4.5:1. At June 30, 2020, the Company’s ratio of 1.7:1 was in compliance with this covenant.

Fair Value

The fair values of cash, 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 “Long-term indebtedness” and “Current indebtedness” and the carrying amounts of derivative instruments are included in “Other financial assets” and “Other financial liabilities”, both current and

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 hedged 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, 2020					Total

Assets	Level 1	Level 2	Level 3			Balance

Money market accounts	-	655	-			655

Warrants (1)	-	-	436			436

(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.

(5)	Used to manage foreign exchange risk on cash flows excluding indebtedness.

The following reflects the change in the fair value of the Refinitiv

arrants, which are a level 3 in the fair value measurement hierarchy, for the six months ended June 30, 2020:



	Six months ended June 30,

	2020
December 31, 2019		435
Gain recognized within other operating gains, net		1
June 30, 2020		436

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, 2020.

Valuation Techniques

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

over-the-counter

derivatives) is deter

ined 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 forward foreign exchange contracts are calculated as the present value of the estimated future cash flows based on observable yield curves; and

●

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

Valuation of the Refinitiv Warrants

On August 1, 2019, the Company and private equity funds affiliated with Blackstone agreed to sell Refinitiv, in which the Company owns a 45%

(1)

interest, to LSEG, in an all share transaction that valued Refinitiv at $27 billion (as of the announcement date), but LSEG may, at its option, settle up to $2.5 billion of the consideration in cash (see note 9). Under the terms of the warrant agreement, the proposed transaction will constitute a change in control whereby the exercise of the warrants in connection with the closing of the transaction will increase the Company’s ownership of Refinitiv from 45%

(1)

to 47.6%

(1)

. Reflecting the entry into a definitive agreement for the sale of the Refinitiv business, the value of the warrants at June 30, 2020 is primarily based on the number of incremental shares in Refinitiv to which the Company is entitled upon closing and the share price of LSEG on June 30, 2020. The valuation also incorporates (on a weighted-average basis) other outcomes based on the likelihood of the proposed transaction closing. In future periods, the warrants will be revalued based on the share price of LSEG at each reporting date and will reflect management’s continuing assessment about the likelihood that the proposed transaction will close, including progress towards obtaining regulatory clearances and satisfying customary closing conditions.

The Monte Carlo simulation approach, which is incorporated into the valuation of the Refinitiv warrants, generates values based on the random outcomes from a probability distribution. Key inputs under the Monte Carlo approach include: the estimated equity value of Refinitiv; the capitalization structure of Refinitiv; the expected volatility; the risk-free rate of return; annual dividends or distributions; and assumptions about the timing of a liquidity event. An increase in the equity value would typically result in an increase in the fair value of the warrants and conversely, a decrease would typically result in a decrease in the fair value of the warrants.

Capital

Note 16: Capital

Share repurchases

The Company may buy back shares (and subsequently cancel them) from time to time as part of its capital strategy. Share repurchases are typically effected under a normal course issuer bid (“NCIB”). Under the NCIB, the Company may repurchase up to 25 million common shares between August 19, 2019 and August 18, 2020 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 if the Company receives an issuer bid exemption order from applicable securities regulatory authorities in Canada for such purchases. The price that the Company will pay for shares in open market transactions under the NCIB will be the market price at the time of purchase or such other price as may be permitted by TSX.

The Company did not repurchase any shares in the three months ended June 30, 2020 and 2019. Details of share repurchases for the six months ended June 30, 2020 and 2019 were as follows:



	Six months ended June 30,

	2020		2019

Share repurchases (millions of U.S. dollars)		200		190

Shares repurchased (number in millions)		2.6		3.5

Share repurchases - average price per share in U.S. dollars		$78.37		$53.93

In October 2019, the Company announced plans to repurchase up to an additional $200 million of its common shares in 2020. These share repurchases were completed in February 2020. Decisions regarding any future repurchases will depend on factors such as market conditions, share price, and other opportunities to invest capital for growth. The Company may elect to suspend or discontinue its 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 20, 2019. As a result, the Company recorded a $200 million liability in “Other financial liabilities” within current liabilities at December 31, 2019 with a corresponding amount recorded in equity in the consolidated statement of financial position.

Dividends

Dividends on common shares are declared in U.S. dollars.

Contingencies

Note 19: 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, defamation claims and intellectual property infringement claims. The outcome of all of the matters against the Company is subject to future resolution, including the uncertainties of litigation. 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. 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.
