Notes to consolidated financial statements (unaudited)

1.  Basis of financial statement preparation

These unaudited consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (GAAP) and follow the same accounting policies and methods of computation as, and should be read in conjunction with, the most recent annual consolidated financial statements filed with the U.S. Securities and Exchange Commission (SEC) in the company’s 2017 annual report on Form 10-K. In the opinion of the company, the information furnished herein reflects all known accruals and adjustments necessary for a fair statement of the results for the periods reported herein. All such adjustments are of a normal recurring nature. Prior year’s data has been reclassified in certain cases to conform to the current presentation basis.

The company’s exploration and production activities are accounted for under the “successful efforts” method.

The results for the six months ended June 30, 2018, are not necessarily indicative of the operations to be expected for the full year.

All amounts are in Canadian dollars unless otherwise indicated.

2.  Accounting changes

Effective January 1, 2018, Imperial adopted the Financial Accounting Standards Board’s standard, Revenue from Contracts with Customers, as amended. The standard establishes a single revenue recognition model for all contracts with customers, eliminates industry and transaction specific requirements, and expands disclosure requirements. The standard was adopted using the modified retrospective method, under which prior year results are not restated, but supplemental information is provided for any material impacts of the standard on 2018 results. The adoption of the standard did not have a material impact on any of the lines reported in the company’s consolidated financial statements. The cumulative effect of adoption of the new standard was de minimis. The company did not elect any practical expedients that require disclosure. See note 4 for additional details.

Effective January 1, 2018, Imperial adopted the Financial Accounting Standards Board’s standard update, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The update requires separate presentation of the service cost component from other components of net benefit costs. The other components are reported in a new line on the company’s consolidated statement of income, “Non-service pension and postretirement benefit”. Imperial elected to use the practical expedient which uses the amounts disclosed in the pension and other postretirement benefit plan note for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements, as it is impracticable to determine the amounts capitalized in those periods. Beginning in 2018, the other components of net benefit costs are included in the Corporate and other expenses. The “Non-service pension and postretirement benefit” line reflects the non-service costs, which primarily includes interest costs, expected return on plan assets, and amortization of actuarial gains and losses, that were previously included in “Production and manufacturing” and “Selling and general” expenses. Additionally, only the service cost component of net benefit costs is eligible for capitalization in situations where it is otherwise appropriate to capitalize employee costs in connection with the construction or production of an asset.

The impact of the retrospective presentation change on Imperial’s consolidated statement of income for the period ended June 30, 2018 is shown below.

	Second Quarter						Six Months to
millions of Canadian dollars	2017						June 30, 2017
	As reported		Change		As   adjusted		As reported		Change		As   adjusted
Production and manufacturing		1,525		(30)		1,495		2,900		(60)		2,840
Selling and general		201		(3)		198		407		(6)		401
Non-service pension and postretirement benefit		-		33		33		-		66		66

Effective January 1, 2018, Imperial adopted the Financial Accounting Standards Board’s standard update, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The standard requires investments in equity securities other than consolidated subsidiaries and equity method investments to be measured at fair value, with changes in the fair value recognized through net income. The company elected a modified approach for equity securities that do not have a readily determinable fair value. This modified approach measures investments at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. There was no cumulative effect related to the adoption of this standard. The carrying value of equity securities without readily determinable fair values as at June 30, 2018 were not significant to Imperial.

The standard also expanded disclosures related to financial statements. The company’s only notable financial instrument is long-term debt ($4,447 million, excluding capitalized lease obligations), where the difference between fair value and carrying value was de minimis. The fair value of long-term debt was primarily a level 2 measurement.

4.  Accounting policy for revenue recognition

Imperial generally sells crude oil, natural gas and petroleum and chemical products under short-term agreements at prevailing market prices. In some cases, products may be sold under long-term agreements, with periodic price adjustments to reflect market conditions.

Revenue is recognized at the amount the company expects to receive when the customer has taken control, which is typically when title transfers and the customer has assumed the risks and rewards of ownership. The prices of certain sales are based on price indexes that are sometimes not available until the next period. In such cases, estimated realizations are accrued when the sale is recognized, and are finalized when final information is available. Such adjustments to revenue from performance obligations satisfied in previous periods are not significant. Payment for revenue transactions is typically due within 30 days. Future volume delivery obligations that are unsatisfied at the end of the period are expected to be fulfilled through ordinary production or purchases. These performance obligations are based on market prices at the time of the transaction and are fully constrained due to market price volatility.

“Revenues” and “Accounts receivable, less estimated doubtful accounts” primarily arise from contracts with customers. Long-term receivables are primarily from non-customers. Contract assets are mainly from marketing assistance programs and are not significant. Contract liabilities are mainly customer prepayments, loyalty programs and accruals of expected volume discounts, and are not significant.

13. Recently issued accounting standards

Effective January 1, 2019, Imperial will adopt the Financial Accounting Standards Board’s standard, Leases (Topic 842), as amended. The standard requires all leases with an initial term greater than one year be recorded on the balance sheet as a right of use asset and a lease liability. The company acquired lease accounting software to facilitate implementation, and is currently installing, configuring and testing the software. Based on leases outstanding at the end of 2017, the company estimates the operating lease right of use asset and lease liability would have been in the range of $200 million to $250 million at that time. The effect on Imperial’s consolidated balance sheet as a result of implementing the standard on January 1, 2019 could differ considerably depending on operating leases commenced in 2018 as well as interest rates and other factors such as the expiry or renewal of leases during the year.

Item 2. Management’s discussion and analysis of financial condition and results of operations

Operating results

Second quarter 2018 vs. second quarter 2017

The company’s net income for the second quarter of 2018 was $196 million or $0.24 per share on a diluted basis, an increase of $273 million compared to the net loss of $77 million or $0.09 per share, for the same period last year.

Upstream recorded a net loss in the second quarter of $6 million compared to a net loss of $201 million in the same period of 2017. Improved results reflect the impact of higher Canadian crude oil realizations of about $280 million, partially offset by higher royalty costs of about $50 million and higher operating expenses of about $50 million mainly associated with planned turnarounds.

West Texas Intermediate (WTI) averaged US$67.91 per barrel in the second quarter of 2018, up from US$48.20 per barrel in the same quarter of 2017. Western Canada Select (WCS) averaged US$48.81 per barrel and US$37.18 per barrel respectively for the same periods. The WTI / WCS differential widened to approximately US$19 per barrel in the second quarter of 2018, from approximately US$11 per barrel in the same period of 2017.

The Canadian dollar averaged US$0.78 in the second quarter of 2018, an increase of US$0.04 from the second quarter of 2017.

Imperial’s average Canadian dollar realizations for bitumen and synthetic crudes increased generally in line with the North American benchmarks, adjusted for changes in exchange rates and transportation costs. Bitumen realizations averaged $48.90 per barrel for the second quarter of 2018, an increase of $10.68 per barrel versus the second quarter of 2017. Synthetic crude realizations averaged $86.31 per barrel, an increase of $21.24 per barrel for the same period of 2017.

Gross production of Cold Lake bitumen averaged 133,000 barrels per day in the second quarter, compared to 160,000 barrels per day in the same period last year. Lower volumes were primarily due to planned maintenance and production timing.

Gross production of Kearl bitumen averaged 180,000 barrels per day in the second quarter (128,000 barrels Imperial’s share), up from 171,000 barrels per day (121,000 barrels Imperial’s share) during the second quarter of 2017. Higher production was mainly the result of mining optimization, partially offset by planned turnaround activities.

The company’s share of gross production from Syncrude averaged 50,000 barrels per day, up from 27,000 barrels per day in the second quarter of 2017. Higher production was due to the absence of the Syncrude Mildred Lake upgrader fire that occurred in March 2017, partially offset by planned turnaround activities and a power disruption that occurred on June 20, 2018, resulting in a complete shutdown of all processing units for the remainder of the second quarter. Recovery from the power outage is ongoing with partial production restored in July and return to full rates anticipated in September.

Downstream net income was $201 million in the second quarter, up from $78 million in the second quarter of 2017. Earnings increased mainly due to stronger margins of about $390 million, partially offset by the impact of increased planned turnaround activity of about $200 million, and the impact of a stronger Canadian dollar.

Refinery throughput averaged 363,000 barrels per day, up from 358,000 barrels per day in the second quarter of 2017. Capacity utilization increased to 86 percent from 85 percent in the second quarter of 2017.

Petroleum product sales were 510,000 barrels per day, up from 486,000 barrels per day in the second quarter of 2017. Sales growth continues to be driven by optimization across the full Downstream value chain, and the expansion of Imperial’s logistics capabilities.

IMPERIAL OIL LIMITED

Chemical net income of $78 million in the second quarter matched best-ever quarterly results. Earnings increased $14 million from the same period of 2017, benefitting from increased volumes and margins.

Corporate and other expenses were $77 million in the second quarter, compared to $18 million in the same period of 2017, primarily due to higher share-based compensation charges. In addition, as part of the implementation of the Financial Accounting Standards Board’s update, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, beginning January 1, 2018, Corporate and other includes all non-service pension and postretirement benefit expenses. Prior to 2018, the majority of these costs were allocated to the operating segments.

IMPERIAL OIL LIMITED

Six months 2018 vs. six months 2017

Net income in the first six months of 2018 was $712 million, or $0.86 per share on a diluted basis, an increase of $456 million compared to a net income of $256 million or $0.30 per share in the first six months of 2017.

Upstream recorded a net loss of $50 million in the first six months of 2018, compared to a net loss of $287 million from the same period of 2017. Improved results reflect the impact of higher Canadian crude oil realizations of about $350 million, partially offset by the impact of higher operating costs of about $50 million mainly associated with planned turnarounds. Results also reflect the impact of higher royalties and the strengthening of the Canadian dollar compared to the prior year.

West Texas Intermediate averaged US$65.44 per barrel in the first six months of 2018, up from US$49.96 per barrel in the prior year. Western Canada Select averaged US$43.74 per barrel and US$37.22 per barrel respectively for the same periods. The WTI / WCS differential widened to approximately US$22 per barrel in the first six months of 2018, from approximately US$13 per barrel in the same period of 2017.

The Canadian dollar averaged US$0.78 in the first six months of 2018, an increase of about US$0.03 from the same period of 2017.

Imperial’s average Canadian dollar realizations for bitumen and synthetic crudes increased generally in line with the North American benchmarks, adjusted for changes in the exchange rate and transportation costs. Bitumen realizations averaged $41.84 per barrel for the first six months of 2018, an increase of $4.63 per barrel versus 2017. Synthetic crude realizations averaged $81.24 per barrel, an increase of $14.24 per barrel from the same period of 2017.

Gross production of Cold Lake bitumen averaged 143,000 barrels per day in the first six months of 2018, compared to 159,000 barrels per day from the same period of 2017. Lower volumes were primarily due to planned maintenance and production timing.

Gross production of Kearl bitumen averaged 181,000 barrels per day in the first six months of 2018 (128,000 barrels Imperial’s share) up from 177,000 barrels per day (125,000 barrels Imperial’s share) from the same period of 2017.

During the first six months of 2018, the company’s share of gross production from Syncrude averaged 57,000 barrels per day, up from 46,000 barrels per day from the same period of 2017. Higher production was due to the absence of the impact associated with the March 2017 fire at the Syncrude Mildred Lake upgrader, partially offset by planned turnaround activities, and a power disruption that occurred on June 20, 2018, resulting in a complete shutdown of all processing units for the remainder of the second quarter. Recovery from the power outage is ongoing with partial production restored in July and return to full rates anticipated in September.

Downstream net income was $722 million, an increase of $264 million versus the prior year. Higher earnings reflect stronger margins of about $690 million, partially offset by the impact of increased planned turnaround activity of about $200 million, the impact of a stronger Canadian dollar of about $60 million and the absence of the $151 million gain on the sale of a surplus property in 2017.

Refinery throughput averaged 386,000 barrels per day in the first six months of 2018, up from 378,000 barrels per day from the same period of 2017. Capacity utilization increased to 91 percent from 90 percent in the same period of 2017.

Petroleum product sales were 494,000 barrels per day in the first six months of 2018, up from 486,000 barrels per day from the same period of 2017. Sales growth continues to be driven by optimization across the full Downstream value chain, and the expansion of Imperial’s logistics capabilities.

Chemical net income was $151 million, up from $109 million in the first half of 2017, primarily due to higher margins and volumes.

19

IMPERIAL OIL LIMITED

Corporate and other expenses were $111 million for the first six months of 2018, compared to $24 million in the same period of 2017, primarily due to higher share-based compensation charges. In addition, beginning January 1, 2018, Corporate and other includes all non-service pension and postretirement benefit expenses. Prior to 2018, the majority of these costs were allocated to the operating segments.

The company’s cash balance was $873 million at June 30, 2018, versus $623 million at the end of second quarter 2017.

Cash flow generated from operating activities was $1,844 million in the first six months of 2018, compared with $846 million from the same period of 2017, reflecting higher earnings and working capital effects.

Investing activities used net cash of $744 million in the first six months of 2018, compared with $220 million used in the same period of 2017, reflecting higher additions to property, plant and equipment, and lower proceeds from asset sales.

Cash used in financing activities was $1,422 million in the first six months of 2018, compared with $394 million used in the same period of 2017. Dividends paid in the first six months of 2018 were $266 million. The per share dividend paid in the first six months of 2018 was $0.32, up from $0.30 from the same period of 2017. During the first six months of 2018, the company purchased about 28.6 million shares for $1,143 million, including shares purchased from Exxon Mobil Corporation.

On April 27, 2018, the company announced by news release that it had received final approval from the Toronto Stock Exchange for an amendment to its normal course issuer bid to increase the number of common shares that it may purchase. Under the amendment, the number of common shares eligible for purchase increased to a maximum of 42,326,545 common shares during the period June 27, 2017 to June 26, 2018.

On June 22, 2018, the company announced by news release that it had received final approval from the Toronto Stock Exchange for a new normal course issuer bid and will continue its existing share purchase program. The program enables the company to purchase up to a maximum of 40,391,196 common shares during the period June 27, 2018 to June 26, 2019. This maximum includes shares purchased under the normal course issuer bid and from Exxon Mobil Corporation concurrent with, but outside of the normal course issuer bid. As in the past, Exxon Mobil Corporation has advised the company that it intends to participate to maintain its ownership percentage at approximately 69.6 percent. The program will end should the company purchase the maximum allowable number of shares, or on June 26, 2019.

Recently issued accounting standards

Effective January 1, 2019, Imperial will adopt the Financial Accounting Standards Board’s standard, Leases (Topic 842), as amended. The standard requires all leases with an initial term greater than one year be recorded on the balance sheet as a right of use asset and a lease liability. The company acquired lease accounting software to facilitate implementation, and is currently installing, configuring and testing the software. Based on leases outstanding at the end of 2017, the company estimates the operating lease right of use asset and lease liability would have been in the range of $200 million to $250 million at that time. The effect on Imperial’s consolidated balance sheet as a result of implementing the standard on January 1, 2019 could differ considerably depending on operating leases commenced in 2018 as well as interest rates and other factors such as the expiry or renewal of leases during the year.

Item 3. Quantitative and qualitative disclosures about market risk

Information about market risks for the six months ended June 30, 2018, does not differ materially from that discussed on page 49 of the company’s annual report on Form 10-K for the year ended December 31, 2017. The following table details those earnings sensitivities that have been updated from the fiscal year-end to reflect current market conditions.

Earnings Sensitivities (a)

millions of Canadian dollars after tax
One dollar (U.S.) per barrel change in heavy crude oil prices	+ (-)	75
Ten cents per thousand cubic feet decrease (increase) in natural gas prices	+ (-)	4
One cent decrease (increase) in the value of the Canadian dollar versus the U.S. dollar	+ (-)	100

(a) Each sensitivity calculation shows the impact on net income resulting from a change in one factor, after tax and royalties and holding all other factors constant. These sensitivities have been updated to reflect current conditions. They may not apply proportionately to larger fluctuations.

Item 4. Controls and procedures

As indicated in the certifications in Exhibit 31 of this report, the company’s principal executive officer and principal financial officer have evaluated the company’s disclosure controls and procedures as of June 30, 2018. Based on that evaluation, these officers have concluded that the company’s disclosure controls and procedures are effective in ensuring that information required to be disclosed by the company in the reports that it files or submits under the Securities Exchange Act of 1934, as amended, is accumulated and communicated to them in a manner that allows for timely decisions regarding required disclosures and are effective in ensuring that such information is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms.

There has not been any change in the company’s internal control over financial reporting during the last fiscal quarter that has materially affected, or is reasonably likely to materially affect, the company’s internal control over financial reporting.

(a) On June 22, 2017, the company announced by news release that it had received final approval from the Toronto Stock Exchange for a normal course issuer bid and continuation of its share purchase program. The program enabled the company to purchase up to a maximum of 25,395,927 common shares during the period June 27, 2017 to June 26, 2018, which includes shares purchased under the normal course issuer bid and from Exxon Mobil Corporation concurrent with, but outside of the normal course issuer bid. Exxon Mobil Corporation participated to maintain its ownership percentage in Imperial at approximately 69.6 percent.

On April 27, 2018, the company announced by news release that it had received final approval from the Toronto Stock Exchange for an amendment to its normal course issuer bid to increase the number of common shares that it may purchase. Under the amendment, the number of common shares eligible for purchase increased to a maximum of 42,326,545 common shares during the period June 27, 2017 to June 26, 2018. No other provisions of the normal course issuer bid were changed.

The program ended on June 26, 2018. Upon expiration, the company had purchased a total of 41,152,059 shares (of the maximum 42,326,545 shares available) under the program.

(b) On June 22, 2018, the company announced by news release that it had received final approval from the Toronto Stock Exchange for a new normal course issuer bid and will continue its existing share purchase program. The program enables the company to purchase up to a maximum of 40,391,196 common shares during the period June 27, 2018 to June 26, 2019. This maximum includes shares purchased under the normal course issuer bid and from Exxon Mobil Corporation concurrent with, but outside of the normal course issuer bid. As in the past, Exxon Mobil Corporation has advised the company that it intends to participate to maintain its ownership percentage at approximately 69.6 percent. The program will end should the company purchase the maximum allowable number of shares, or on June 26, 2019.

(c) In its most recent quarterly earnings release, the company stated that it currently anticipates exercising its share purchases uniformly over the duration of the program. Purchase plans may be modified at any time without prior notice.

The company will continue to evaluate its share purchase program in the context of its overall capital activities.

Basis of financial statement preparation

1.  Basis of financial statement preparation

These unaudited consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (GAAP) and follow the same accounting policies and methods of computation as, and should be read in conjunction with, the most recent annual consolidated financial statements filed with the U.S. Securities and Exchange Commission (SEC) in the company’s 2017 annual report on Form 10-K. In the opinion of the company, the information furnished herein reflects all known accruals and adjustments necessary for a fair statement of the results for the periods reported herein. All such adjustments are of a normal recurring nature. Prior year’s data has been reclassified in certain cases to conform to the current presentation basis.

The company’s exploration and production activities are accounted for under the “successful efforts” method.

The results for the six months ended June 30, 2018, are not necessarily indicative of the operations to be expected for the full year.

All amounts are in Canadian dollars unless otherwise indicated.

2.  Accounting changes

Effective January 1, 2018, Imperial adopted the Financial Accounting Standards Board’s standard, Revenue from Contracts with Customers, as amended. The standard establishes a single revenue recognition model for all contracts with customers, eliminates industry and transaction specific requirements, and expands disclosure requirements. The standard was adopted using the modified retrospective method, under which prior year results are not restated, but supplemental information is provided for any material impacts of the standard on 2018 results. The adoption of the standard did not have a material impact on any of the lines reported in the company’s consolidated financial statements. The cumulative effect of adoption of the new standard was de minimis. The company did not elect any practical expedients that require disclosure. See note 4 for additional details.

Effective January 1, 2018, Imperial adopted the Financial Accounting Standards Board’s standard update, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The update requires separate presentation of the service cost component from other components of net benefit costs. The other components are reported in a new line on the company’s consolidated statement of income, “Non-service pension and postretirement benefit”. Imperial elected to use the practical expedient which uses the amounts disclosed in the pension and other postretirement benefit plan note for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements, as it is impracticable to determine the amounts capitalized in those periods. Beginning in 2018, the other components of net benefit costs are included in the Corporate and other expenses. The “Non-service pension and postretirement benefit” line reflects the non-service costs, which primarily includes interest costs, expected return on plan assets, and amortization of actuarial gains and losses, that were previously included in “Production and manufacturing” and “Selling and general” expenses. Additionally, only the service cost component of net benefit costs is eligible for capitalization in situations where it is otherwise appropriate to capitalize employee costs in connection with the construction or production of an asset.

The impact of the retrospective presentation change on Imperial’s consolidated statement of income for the period ended June 30, 2018 is shown below.

Non-service pension and postretirement benefit		-		33		33		-		66		66

Effective January 1, 2018, Imperial adopted the Financial Accounting Standards Board’s standard update, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The standard requires investments in equity securities other than consolidated subsidiaries and equity method investments to be measured at fair value, with changes in the fair value recognized through net income. The company elected a modified approach for equity securities that do not have a readily determinable fair value. This modified approach measures investments at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. There was no cumulative effect related to the adoption of this standard. The carrying value of equity securities without readily determinable fair values as at June 30, 2018 were not significant to Imperial.

The standard also expanded disclosures related to financial statements. The company’s only notable financial instrument is long-term debt ($4,447 million, excluding capitalized lease obligations), where the difference between fair value and carrying value was de minimis. The fair value of long-term debt was primarily a level 2 measurement.

Accounting policy for revenue recognition

4.  Accounting policy for revenue recognition

Imperial generally sells crude oil, natural gas and petroleum and chemical products under short-term agreements at prevailing market prices. In some cases, products may be sold under long-term agreements, with periodic price adjustments to reflect market conditions.

Revenue is recognized at the amount the company expects to receive when the customer has taken control, which is typically when title transfers and the customer has assumed the risks and rewards of ownership. The prices of certain sales are based on price indexes that are sometimes not available until the next period. In such cases, estimated realizations are accrued when the sale is recognized, and are finalized when final information is available. Such adjustments to revenue from performance obligations satisfied in previous periods are not significant. Payment for revenue transactions is typically due within 30 days. Future volume delivery obligations that are unsatisfied at the end of the period are expected to be fulfilled through ordinary production or purchases. These performance obligations are based on market prices at the time of the transaction and are fully constrained due to market price volatility.

“Revenues” and “Accounts receivable, less estimated doubtful accounts” primarily arise from contracts with customers. Long-term receivables are primarily from non-customers. Contract assets are mainly from marketing assistance programs and are not significant. Contract liabilities are mainly customer prepayments, loyalty programs and accruals of expected volume discounts, and are not significant.

The 12-month normal course issuer bid program that was in place during the second quarter of 2018 came into effect in June of 2017 and was amended on April 27, 2018. The program enabled the company to purchase up to a maximum of 42,326,545 common shares (5 percent of the total shares on June 13, 2017), which included shares purchased under the normal course issuer bid and from Exxon Mobil Corporation concurrent with, but outside of the normal course issuer bid. Exxon Mobil Corporation participated to maintain its ownership percentage in Imperial at approximately 69.6 percent.

The company announced another 12-month normal course issuer bid program effective June 27, 2018 and will continue its existing share purchase program. The program enables the company to purchase up to a maximum of 40,391,196 common shares (5 percent of the total shares on June 13, 2018) which includes shares purchased under the normal course issuer bid and from Exxon Mobil Corporation concurrent with, but outside of the normal course issuer bid. As in the past, Exxon Mobil Corporation has advised the company that it intends to participate to maintain its ownership percentage at approximately 69.6 percent.

The excess of the purchase cost over the stated value of shares purchased has been recorded as a distribution of earnings reinvested.

13. Recently issued accounting standards

Effective January 1, 2019, Imperial will adopt the Financial Accounting Standards Board’s standard, Leases (Topic 842), as amended. The standard requires all leases with an initial term greater than one year be recorded on the balance sheet as a right of use asset and a lease liability. The company acquired lease accounting software to facilitate implementation, and is currently installing, configuring and testing the software. Based on leases outstanding at the end of 2017, the company estimates the operating lease right of use asset and lease liability would have been in the range of $200 million to $250 million at that time. The effect on Imperial’s consolidated balance sheet as a result of implementing the standard on January 1, 2019 could differ considerably depending on operating leases commenced in 2018 as well as interest rates and other factors such as the expiry or renewal of leases during the year.

Accounting changes

Effective January 1, 2018, Imperial adopted the Financial Accounting Standards Board’s standard, Revenue from Contracts with Customers, as amended. The standard establishes a single revenue recognition model for all contracts with customers, eliminates industry and transaction specific requirements, and expands disclosure requirements. The standard was adopted using the modified retrospective method, under which prior year results are not restated, but supplemental information is provided for any material impacts of the standard on 2018 results. The adoption of the standard did not have a material impact on any of the lines reported in the company’s consolidated financial statements. The cumulative effect of adoption of the new standard was de minimis. The company did not elect any practical expedients that require disclosure. See note 4 for additional details.

Effective January 1, 2018, Imperial adopted the Financial Accounting Standards Board’s standard update, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The update requires separate presentation of the service cost component from other components of net benefit costs. The other components are reported in a new line on the company’s consolidated statement of income, “Non-service pension and postretirement benefit”. Imperial elected to use the practical expedient which uses the amounts disclosed in the pension and other postretirement benefit plan note for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements, as it is impracticable to determine the amounts capitalized in those periods. Beginning in 2018, the other components of net benefit costs are included in the Corporate and other expenses. The “Non-service pension and postretirement benefit” line reflects the non-service costs, which primarily includes interest costs, expected return on plan assets, and amortization of actuarial gains and losses, that were previously included in “Production and manufacturing” and “Selling and general” expenses. Additionally, only the service cost component of net benefit costs is eligible for capitalization in situations where it is otherwise appropriate to capitalize employee costs in connection with the construction or production of an asset.

Effective January 1, 2018, Imperial adopted the Financial Accounting Standards Board’s standard update, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The standard requires investments in equity securities other than consolidated subsidiaries and equity method investments to be measured at fair value, with changes in the fair value recognized through net income. The company elected a modified approach for equity securities that do not have a readily determinable fair value. This modified approach measures investments at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. There was no cumulative effect related to the adoption of this standard. The carrying value of equity securities without readily determinable fair values as at June 30, 2018 were not significant to Imperial.

The standard also expanded disclosures related to financial statements. The company’s only notable financial instrument is long-term debt ($4,447 million, excluding capitalized lease obligations), where the difference between fair value and carrying value was de minimis. The fair value of long-term debt was primarily a level 2 measurement.

Accounting policy for revenue recognition

Imperial generally sells crude oil, natural gas and petroleum and chemical products under short-term agreements at prevailing market prices. In some cases, products may be sold under long-term agreements, with periodic price adjustments to reflect market conditions.

Revenue is recognized at the amount the company expects to receive when the customer has taken control, which is typically when title transfers and the customer has assumed the risks and rewards of ownership. The prices of certain sales are based on price indexes that are sometimes not available until the next period.

“Revenues” and “Accounts receivable, less estimated doubtful accounts” primarily arise from contracts with customers. Long-term receivables are primarily from non-customers. Contract assets are mainly from marketing assistance programs and are not significant. Contract liabilities are mainly customer prepayments, loyalty programs and accruals of expected volume discounts, and are not significant.
