8.    Financial and derivative instruments

Financial instruments

The fair value of the company’s financial instruments is determined by reference to various market data and other appropriate valuation techniques. There are no material differences between the fair value of the company’s financial instruments and the recorded carrying value. At September 30, 2023 and December 31, 2022, the fair value of long-term debt ($3,447 million, excluding finance lease obligations) was primarily a level 2 measurement.

Derivative instruments

The company’s size, strong capital structure and the complementary nature of its business segments reduce the company’s enterprise-wide risk from changes in commodity prices and currency exchange rates. In addition, the company uses commodity-based contracts, including derivatives, to manage commodity price risk and to generate returns from trading. Commodity contracts held for trading purposes are presented in the Consolidated statement of income on a net basis in the line “Revenues” and in the Consolidated statement of cash flows in "Cash flow from (used in) operating activities". The company does not designate derivative instruments as a hedge for hedge accounting purposes.

Credit risk associated with the company’s derivative position is mitigated by several factors, including the use of derivative clearing exchanges and the quality of and financial limits placed on derivative counterparties. The company maintains a system of controls that includes the authorization, reporting and monitoring of derivative activity.

The net notional long/(short) position of derivative instruments was:

	As at Sep 30	As at Dec 31

Crude	3,280	1,800
Products	(850)	(350)

The most recent 12-month normal course issuer bid program came into effect June 29, 2023 under which Imperial continued its existing share purchase program. The program enabled the company to purchase up to a maximum of 29,207,635 common shares (5 percent of the total shares on June 15, 2023) 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. As in the past, Exxon Mobil Corporation advised the company that it intended to participate to maintain its ownership percentage at approximately 69.6 percent. Imperial accelerated its share purchases under the normal course issuer bid program during the third quarter and, subsequent to the end of the third quarter, the program completed on October 19, 2023 as a result of the company purchasing the maximum allowable number of shares under the program.

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

On October 27, 2023, the company announced its intention to launch a substantial issuer bid pursuant to which the company will offer to purchase for cancellation up to $1.5 billion of its common shares. The substantial issuer bid will be made through a modified Dutch auction, with a tender price range to be determined by the company at the time of commencement of the offer. Shares may also be tendered by way of a proportionate tender, which will result in a shareholder maintaining their proportionate share ownership. ExxonMobil has advised Imperial that it intends to make a proportionate tender in connection with the offer in order to maintain its proportionate share ownership at approximately 69.6 percent following completion of the offer. Nothing in this report shall constitute an offer to purchase or a solicitation of an offer to sell any shares.

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

Non-GAAP financial measures and other specified financial measures

Certain measures included in this document are not prescribed by U.S. Generally Accepted Accounting Principles (GAAP). These measures constitute “non-GAAP financial measures” under Securities and Exchange Commission Regulation G and Item 10(e) of Regulation S-K, and “specified financial measures” under National Instrument 52-112 Non-GAAP and Other Financial Measures Disclosure of the Canadian Securities Administrators.

Reconciliation of these non-GAAP financial measures to the most comparable GAAP measure, and other information required by these regulations, have been provided. Non-GAAP financial measures and specified financial measures are not standardized financial measures under GAAP and do not have a standardized definition. As such, these measures may not be directly comparable to measures presented by other companies, and should not be considered a substitute for GAAP financial measures.

Net income (loss) excluding identified items

Net income (loss) excluding identified items is a non-GAAP financial measure that is total net income (loss) excluding individually significant non-operational events with an absolute corporate total earnings impact of at least $100 million in a given quarter. The net income (loss) impact of an identified item for an individual segment in a given quarter may be less than $100 million when the item impacts several segments or several periods. The most directly comparable financial measure that is disclosed in the financial statements is "Net income (loss)" within the company’s Consolidated statement of income. Management uses these figures to improve comparability of the underlying business across multiple periods by isolating and removing significant non-operational events from business results. The company believes this view provides investors increased transparency into business results and trends, and provides investors with a view of the business as seen through the eyes of management. Net income (loss) excluding identified items is not meant to be viewed in isolation or as a substitute for net income (loss) as prepared in accordance with U.S. GAAP. All identified items are presented on an after-tax basis.

Recent business environment

During the first quarter of 2023, the price of crude oil declined, impacted by higher inventory levels, and the price of crude oil remained relatively flat during the second quarter. In the third quarter, crude oil prices increased as demand exceeded supply after OPEC+ oil producers further reduced oil output. In addition, the Canadian WTI/WCS spread continued to recover in the third quarter, but remains weaker than 2022 on an annual basis. Similarly, 2023 refining margins remain strong but fall short of 2022 levels on an annual basis.

Net income (loss) factor analysis

millions of Canadian dollars

Price – Synthetic crude oil realizations decreased by $11.82 per barrel, generally in line with WTI. Average bitumen realizations increased by $4.47 per barrel. Higher bitumen realizations were primarily driven by the narrowing of the WTI/WCS spread, partially offset by lower marker prices.

Volumes – Higher volumes were primarily driven by increased plant capacity utilization and mine equipment productivity at Kearl, and annual turnaround timing and duration at Syncrude, partially offset by steam cycle timing and planned turnaround activity at Cold Lake.

Identified Items1 – Prior year third quarter results included favourable identified items1 related to the company's gain on the sale of interests in XTO Energy Canada.

Other – Includes lower operating expenses of about $160 million, and favourable foreign exchange impacts of about $80 million.

(a)Share repurchases were made under the company's normal course issuer bid program. In the second quarter of 2022, share repurchases were made under the company's substantial issuer bid that commenced on May 6, 2022 and expired on June 10, 2022. Includes shares purchased from Exxon Mobil Corporation concurrent with, but outside of, the normal course issuer bid, and by way of a proportionate tender under the company's substantial issuer bid.

On June 27, 2023, the company announced by news release that it had received final approval from the Toronto Stock Exchange for a new normal course issuer bid to continue its then existing share purchase program. The program enabled the company to purchase up to a maximum of 29,207,635 common shares during the period June 29, 2023 to June 28, 2024. This maximum included 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 advised the company that it intended to participate to maintain its ownership percentage at approximately 69.6 percent. Imperial accelerated share purchases under the normal course issuer bid program during the third quarter and, subsequent to the end of the third quarter, the program completed on October 19, 2023 as a result of the company purchasing the maximum allowable number of shares under the program.

On October 27, 2023, the company announced its intention to launch a substantial issuer bid pursuant to which the company will offer to purchase for cancellation up to $1.5 billion of its common shares. The substantial issuer bid will be made through a modified Dutch auction, with a tender price range to be determined by the company at the time of commencement of the offer. Shares may also be tendered by way of a proportionate tender, which will result in a shareholder maintaining their proportionate share ownership. ExxonMobil has advised Imperial that it intends to make a proportionate tender in connection with the offer in order to maintain its proportionate share ownership at approximately 69.6 percent following completion of the offer. Nothing in this report shall constitute an offer to purchase or a solicitation of an offer to sell any shares.

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.

Item 2. Unregistered sales of equity securities and use of proceeds

Issuer purchases of equity securities

	Total number of shares purchased	Average price paid per share (Canadian dollars)	Total number of shares purchased as part of publicly announced plans or programs	Maximum number of shares that may yet be purchased under the plans or programs (a)
July 2023
(July 1 - July 31)	2,283,731	66.72	2,283,731	26,923,904
August 2023
(August 1 - August 31)	5,923,101	74.12	5,923,101	21,000,803

(a)On June 27, 2023, 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 to continue its existing share purchase program. The program enabled the company to purchase up to a maximum of 29,207,635 common shares during the period June 29, 2023 to June 28, 2024. This maximum included 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 advised the company that it intended to participate to maintain its ownership percentage at approximately 69.6 percent. Imperial accelerated its share purchases under the normal course issuer bid program during the third quarter and, subsequent to the end of the third quarter, the program completed on October 19, 2023 as a result of the company purchasing the maximum allowable number of shares under the program.

On October 27, 2023, the company announced its intention to launch a substantial issuer bid pursuant to which the company will offer to purchase for cancellation up to $1.5 billion of its common shares. The substantial issuer bid will be made through a modified Dutch auction, with a tender price range to be determined by the company at the time of commencement of the offer. Shares may also be tendered by way of a proportionate tender, which will result in a shareholder maintaining their proportionate share ownership. ExxonMobil has advised Imperial that it intends to make a proportionate tender in connection with the offer in order to maintain its proportionate share ownership at approximately 69.6 percent following completion of the offer. Nothing in this report shall constitute an offer to purchase or a solicitation of an offer to sell any shares.

The company will continue to evaluate its share purchase program in the context of its overall capital activities. Purchase plans may be modified at any time without prior notice.

Item 5. Other information

During the three months ended September 30, 2023, none of the Company's directors or officers adopted or terminated a "Rule 10b5-1 trading arrangement" or "non-Rule 10b5-1 trading arrangement," as each term is defined in Item 408(a) of Regulation S-K.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Financial and derivative instruments

Financial and derivative instruments

Financial instruments

The fair value of the company’s financial instruments is determined by reference to various market data and other appropriate valuation techniques. There are no material differences between the fair value of the company’s financial instruments and the recorded carrying value. At September 30, 2023 and December 31, 2022, the fair value of long-term debt ($3,447 million, excluding finance lease obligations) was primarily a level 2 measurement.

Derivative instruments

The company’s size, strong capital structure and the complementary nature of its business segments reduce the company’s enterprise-wide risk from changes in commodity prices and currency exchange rates. In addition, the company uses commodity-based contracts, including derivatives, to manage commodity price risk and to generate returns from trading. Commodity contracts held for trading purposes are presented in the Consolidated statement of income on a net basis in the line “Revenues” and in the Consolidated statement of cash flows in "Cash flow from (used in) operating activities". The company does not designate derivative instruments as a hedge for hedge accounting purposes.

Credit risk associated with the company’s derivative position is mitigated by several factors, including the use of derivative clearing exchanges and the quality of and financial limits placed on derivative counterparties. The company maintains a system of controls that includes the authorization, reporting and monitoring of derivative activity.

The net notional long/(short) position of derivative instruments was:

	As at Sep 30	As at Dec 31
thousands of barrels	2023	2022
Crude	3,280	1,800
Products	(850)	(350)

Realized and unrealized gain/(loss) on derivative instruments recognized in the Consolidated statement of income is included in the following lines on a before-tax basis:

	Third Quarter		Nine Months     to September 30
millions of Canadian dollars	2023	2022	2023	2022
Revenues	6	105	(7)	91

The estimated fair value of derivative instruments, and the related hierarchy level for the fair value measurement were as follows:

At September 30, 2023
millions of Canadian dollars
	Fair value				Effect of counterparty netting	Effect of collateral netting	Net carrying value

The most recent 12-month normal course issuer bid program came into effect June 29, 2023 under which Imperial continued its existing share purchase program. The program enabled the company to purchase up to a maximum of 29,207,635 common shares (5 percent of the total shares on June 15, 2023) 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. As in the past, Exxon Mobil Corporation advised the company that it intended to participate to maintain its ownership percentage at approximately 69.6 percent. Imperial accelerated its share purchases under the normal course issuer bid program during the third quarter and, subsequent to the end of the third quarter, the program completed on October 19, 2023 as a result of the company purchasing the maximum allowable number of shares under the program.

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

On October 27, 2023, the company announced its intention to launch a substantial issuer bid pursuant to which the company will offer to purchase for cancellation up to $1.5 billion of its common shares. The substantial issuer bid will be made through a modified Dutch auction, with a tender price range to be determined by the company at the time of commencement of the offer. Shares may also be tendered by way of a proportionate tender, which will result in a shareholder maintaining their proportionate share ownership. ExxonMobil has advised Imperial that it intends to make a proportionate tender in connection with the offer in order to maintain its proportionate share ownership at approximately 69.6 percent following completion of the offer. Nothing in this report shall constitute an offer to purchase or a solicitation of an offer to sell any shares.
