Summary of significant accounting policies

These interim consolidated financial statements have been prepared using accounting principles generally accepted in the United States (“U.S. GAAP”) and include the accounts of Trilogy and its wholly owned subsidiary, NovaCopper US Inc. (dba “Trilogy Metals US”). All significant intercompany transactions are eliminated on consolidation. For variable interest entities (“VIEs”) where Trilogy is not the primary beneficiary, we use the equity method of accounting.

All figures are in United States dollars unless otherwise noted. References to CAD$ refer to amounts in Canadian dollars.

The unaudited interim consolidated financial statements include all adjustments necessary for the fair presentation of the Company’s financial position as of May 31, 2020 and our results of operations and cash flows for the six months ended May 31, 2020 and May 31, 2019. The results of operations for the six months ended May 31, 2020 are not necessarily indicative of the results to be expected for the fiscal year ending November 30, 2020.

As these interim consolidated financial statements do not contain all of the disclosures required by U.S. GAAP for annual financial statements, these unaudited interim consolidated financial statements should be read in conjunction with the annual financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended November 30, 2019, filed with the U.S. Securities and Exchange Commission (“SEC”) and Canadian securities regulatory authorities on February 13, 2020.

These interim consolidated financial statements were approved by the Company’s Audit Committee on behalf of the Board of Directors for issue on July 7, 2020.

Accounting standards adopted

Leases

In February 2016, the FASB issued new accounting requirements for accounting for, presentation of, and classification of leases (“ASU 2016-02”) which, together with subsequent amendments, is included in ASC 842, Leases. ASC 842 became effective for the Company as of December 1, 2019.

The Company adopted ASC 842 using the modified retrospective transition method by applying the transition provision and recording our cumulative adjustment to opening deficit at the beginning of the period of adoption on December 1, 2019, rather than at the beginning of the comparative period presented. Therefore, in the comparative periods, we continue to apply the legacy guidance in ASC 840, including its disclosure requirements. We elected to apply all of the transition practical expedients available, including:

the package of three practical expedients to (1) not reassess whether any expired or existing contracts are or contain leases, (2) not reassess the lease classification for any expired or existing leases, and (3) not reassess initial direct costs for any existing lease;

the hindsight practical expedient to use hindsight when determining lease term and assessing impairment of right-of-use assets, if any; and

the easements practical expedient to continue applying our current policy for accounting for any land easements expired before or existing as of December 1, 2019.

In addition, we elected to apply the short-term lease recognition exemption and elected to apply the practical expedient to not separate lease and non-lease components for all applicable leases on transition. The adoption of this new standard resulted in the recognition of right of use assets and lease liabilities of $786,000 as at December 1, 2019.

New accounting policy

Investment in affiliates

Investments in unconsolidated ventures over which the Company has the ability to exercise significant influence, but does not control, are accounted for under the equity method and include the Company’s investment in the Ambler Metals project. We identified Ambler Metals LLC as a VIE as the entity is dependent on funding from its owners. All funding, ownership, voting rights and power to exercise control is shared equally on a 50/50 basis between the owners of the VIE. Therefore, the Company has determined that it is not the primary beneficiary of the VIE. The Company’s maximum exposure to loss is its investment in Ambler Metals LLC.

Ambler Metals LLC is a non-publicly traded equity investee holding exploration and development projects. The Company reviews and evaluates its investment in affiliates for other than temporary impairment when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Events that could indicate impairment of an investment in affiliates include a significant decrease in long-term expected commodity prices, a significant increase in expected operating or capital costs, unfavorable exploration results or technical studies, a significant decrease in reserves, a loss of significant mineral claims or a change in the development plan or strategy for the project. Asset impairment is considered to exist if the total estimated future cash flows on an undiscounted basis are less than the carrying amount of the asset. If the underlying assets are not recoverable, an impairment loss is measured and recorded based on the difference between the carrying amount of the investee and its estimated fair value which may be determined using a discounted cash flow model.
