NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)

1. REPORTING ENTITY AND DESCRIPTION OF THE BUSINESS

Suncor Energy Inc. (Suncor or the company) is an integrated energy company headquartered in Canada. Suncor's operations include oil sands development and upgrading, onshore and offshore oil and gas production, petroleum refining, and product marketing primarily under the Petro-Canada brand. The consolidated financial statements of the company comprise the company and its subsidiaries and the company's interests in associates and joint arrangements.

The address of the company's registered office is 150 – 6th Avenue S.W., Calgary, Alberta, Canada, T2P 3E3.

2. BASIS OF PREPARATION

(a) Statement of Compliance

These condensed interim consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS), specifically International Accounting Standard (IAS) 34 Interim Financial Reporting as issued by the International Accounting Standards Board. They are condensed as they do not include all of the information required for full annual financial statements, and they should be read in conjunction with the consolidated financial statements for the year ended December 31, 2014.

The policies applied in these condensed interim consolidated financial statements are based on IFRS issued and outstanding as at December 31, 2014.

Comparative figures have been reclassified to conform to the current year financial statement presentation for certain gas purchases consumed in the secondary upgrading process in the Oil Sands segment, which are now classified as Purchases rather than Operating, Selling and General, and shipping-related charges in the Refining and Marketing segment, which are now classified as Transportation rather than Operating, Selling and General.

(b) Basis of Measurement

The consolidated financial statements are prepared on a historical cost basis except as detailed in the accounting policies disclosed in the company's consolidated financial statements for the year ended December 31, 2014.

(c) Functional Currency and Presentation Currency

These consolidated financial statements are presented in Canadian dollars, which is the company's functional currency.

(d) Use of Estimates and Judgment

The timely preparation of financial statements requires that management make estimates and assumptions and use judgment. Accordingly, actual results may differ from estimated amounts as future confirming events occur. Significant estimates and judgment used in the preparation of the financial statements are described in the company's consolidated financial statements for the year ended December 31, 2014.

(e) Income taxes

The company recognizes the impacts of income tax rate changes in earnings in the period the rate change is substantively enacted.

SUNCOR ENERGY INC. 2015 SECOND QUARTER 47

3. SEGMENTED INFORMATION

The company's operating segments are reported based on the nature of their products and services and management responsibility.

5. ASSET IMPAIRMENT

Oil Sands

Joslyn Mining Project

During the second quarter of 2014, the company recognized an impairment charge of $718 million (net of taxes of $248 million) related to the company's interest in the Joslyn mining project, charged against Property, Plant and Equipment ($318 million) and Exploration and Evaluation assets ($400 million). As a result of the company's assessment of expected future net cash flows and the uncertainty of the project, including the timing of the development plans, the company performed an impairment test at June 30, 2014 using a fair value less cost of disposal methodology, with a discounted cash flow approach.

The remaining carrying value of the company's share of the Joslyn mining project as at June 30, 2015 was $400 million.

Other

In the second quarter of 2014, the company recorded an impairment charge of $223 million (net of taxes of $77 million) in the Oil Sands segment following a review of certain assets that no longer fit with Suncor's previously revised growth strategies and which could not be repurposed or otherwise deployed. Such assets included a pipeline and related compressor, as well as steam generator components.

Exploration and Production

Libya

During the second quarter of 2014, the company recognized an after-tax impairment charge of $297 million related to its Libyan assets, charged against Property, Plant and Equipment ($129 million) and Exploration and Evaluation assets ($168 million). As a result of shut-in production due to the continued closure of certain Libyan export terminals and the company's production plans for the remaining term of the Exploration and Production Sharing Agreements, the company performed an impairment test at June 30, 2014 using a fair value less cost of disposal methodology, with a discounted cash flow approach.

The remaining carrying value of the company's net assets in Libya as at June 30, 2015 was approximately $375 million.

9. INCOME TAXES

In the second quarter of 2015, the Government of Alberta enacted an increase in the corporate income tax rate from 10% to 12% effective July 1, 2015. As a result, the company revalued its deferred income tax balances, resulting in a deferred income tax expense of $423 million.

In the first quarter of 2015, the United Kingdom (U.K.) government decreased the supplementary rate on oil and gas profits in the North Sea that reduced the statutory tax rate on Suncor's earnings in the U.K. from 62% to 50%. The company revalued its deferred income tax balances, resulting in a one-time decrease to deferred income taxes of $406 million.

Pursuant to the previously disclosed 2013 proposal letter from the Canada Revenue Agency (CRA), the company received a Notice of Reassessment (NOR) from the CRA during the second quarter of 2014, regarding the income tax treatment of realized losses in 2007 on the settlement of certain derivative contracts. The total amount of the NOR, including tax, penalty and interest, was approximately $920 million. The company strongly disagrees with the CRA's position and continues to firmly believe it will be able to successfully defend its original filing position and will take the appropriate actions to resolve this matter. In addition to the above, the company has:

•
  Received NORs related to the derivative contracts from the Provinces of Alberta, Ontario and Quebec for approximately $124 million, $100 million and $42 million, respectively;
•
  Provided security to the CRA and the Provinces of Quebec and Ontario for approximately $635 million;
•
  Filed Notices of Objection with the CRA and the Provinces of Alberta, Ontario and Quebec; and
•
  Filed a Notice of Appeal with the Tax Court of Canada in November 2014 and is now pursuing its Appeal to that Court.

If the company is unsuccessful in defending its tax filing position, it could be subject to an earnings and cash impact of up to $1.2 billion.

(1)
  Cash payment alternatives are accounted for as cash-settled plans. As these awards can be exchanged for common shares of the company, they are considered potentially dilutive and are included in the calculation of the company's diluted net earnings per share if they have a dilutive impact in the period. Accounting for these awards as equity-settled was determined to have a dilutive impact for the three and six months ended June 30, 2015.

Assets Available for Sale related to the company's investment in Pioneer Energy.

During the second quarter of 2015, Suncor completed the sale, resulting in a realized after-tax gain of $68 million.

The company uses forward starting interest rate swaps to mitigate its exposure to the effect of future interest rate movements on future debt issuances. As at June 30, 2015, the company had executed US$500 million in forward swaps.

The estimated fair value of long-term debt is based on pricing sourced from market data.

12. PROVISIONS

During the six months ended June 30, 2015, there was a net increase in provisions of $428 million, primarily due to a $375 million increase in the decommissioning and restoration provision as a result of a decrease in the credit-adjusted risk-free interest rate.

13. SUBSEQUENT EVENT

On July 7, 2015, Suncor announced that it had reached an agreement with TransAlta Corporation to exchange Suncor's Kent Breeze and its share of the Wintering Hills wind power facilities for TransAlta's Poplar Creek cogeneration facilities. As part of the agreement, Suncor has entered into a 15-year lease to acquire two gas turbine generators and heat recovery steam generators at Poplar Creek.
