Financial instruments

A. Fair values of financial instruments

The Company categorizes its financial assets and liabilities measured at fair value into a three-level hierarchy established by GAAP that prioritizes those inputs to valuation techniques used to measure fair value based on the degree to which they are observable. The three levels of the fair value hierarchy are as follows: Level 1 inputs are quoted prices in active markets for identical assets and liabilities; Level 2 inputs, other than quoted prices included within Level 1, are observable for the asset or liability either directly or indirectly; and Level 3 inputs are not observable in the market.

The Company’s short-term financial instruments may include cash and cash equivalents, restricted cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, and short-term borrowings including commercial paper and term loans. The carrying values of short-term financial instruments approximate their fair values.

The carrying value of the Company’s long-term debt and finance lease liabilities does not approximate their fair value. Their estimated fair value has been determined based on market information, where available, or by discounting future payments of principal and interest at estimated interest rates expected to be available to the Company at period end. All measurements are classified as Level 2. The Company’s long-term debt and finance lease liabilities, including current maturities, with a carrying value of $18,858 million as at June 30, 2022 (December 31, 2021 - $19,151 million), had a fair value of $17,570 million (December 31, 2021 - $21,265 million).
