(1) Marketable securities of publicly quoted companies, consisting of FVTOCI investments are valued using a market approach based upon unadjusted quoted prices in an active market obtained from securities exchanges. The fair value disclosed for our Notes is also included in Level 1, as the basis of valuation uses a quoted price in an active market. (2) Trade receivables from provisional invoices are included in Level 2 as the basis of valuation uses quoted commodity forward prices. Accrued liabilities relating to DSUs, RSUs, and PSUs and derivative assets and liabilities are included in Level 2 as the basis of valuation uses quoted prices in active markets. (3) Certain items of deferred consideration from the sale of exploration and evaluation assets (note 8) is included in Level 3, as certain assumptions used in the calculation of the fair value are not based on observable market data as detailed in note 2(r)(v). During the year ended December 31, 2018, we transferred $nil from Level 3 to Level 1. During 2017, we transferred $2,057,000 from Level 3 to Level 1 following the reverse take-over ("RTO") of Huayra Minerals Corporation ("HMC") the shares of a previously private company that we classified as Level 3 became publicly traded as AbraPlata Resource Corp. and the fair value is now based upon observable market data (note 8).
