    (d)
    Financial assets -
     
    The Company determines the classification of its financial assets at initial recognition in accordance with IAS 39, “Financial Instruments: Recognition and Measurement”. Financial assets are recognized initially at fair value plus the direct costs attributable to the transaction. The Company’s financial assets include cash and cash equivalents, accounts receivable and embedded derivatives.
     
    Cash and cash equivalents -
     
    Cash and cash equivalents are financial assets that may be liquidated immediately, such as bank checking accounts, and other liquid investments with original maturities of three months or less.
     
    Accounts Receivables -
     
    The Company’s receivables include current and long-term trade and other accounts receivable. These receivables are stated at their transaction value, net of an allowance for doubtful accounts. Trade accounts receivable are generated primarily from the Company’s concentrate and cathode sales, are denominated in US dollars, have current maturities, do not bear interest and have no specific guarantees.
     
    Receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. After initial measurement, receivables are subsequently carried at amortized cost using the effective interest rate method less any provision for impairment (i.e. allowance for doubtful accounts).
     
    The Company assesses whether, as of the date of the financial statements, there is objective evidence of impairment in the value of the receivable. Any resulting impairment is measured as the difference between the book value of the receivable and the present value of the estimated future cash flows, discounted at an original effective interest rate or one applicable to a similar transaction. The carrying amount of the receivable is reduced by means of an allowance account and recognized in the statements of comprehensive income.
     
    Embedded derivatives –
     
    Copper Sales -
     
    The Company’s copper sales are provisionally priced at the time of shipment. The provisional prices are finalized in a specified future month based on quoted London Metal Exchange (LME) monthly average prices. The Company receives market prices based on prices in the specified future month, which results in price fluctuations recorded through revenues until the date of settlement. The Company records revenues and invoices customers at the time of shipment based on then-current LME prices, which results in an embedded derivative that is required to be separated from the main contract. The Company’s embedded derivatives from sales are measured at fair value (based on LME spot copper prices) with subsequent changes recognized in the statements of comprehensive income until the month of settlement.
     
    Molybdenum Sales -
     
    The Company’s molybdenum sales are also provisionally priced at the time of shipment. The Company records revenues and invoices customers at the time of shipment based on the arithmetic mean of the high and low Metals Week Dealer Oxide (MWDO) price. The provisional prices are finalized in a future month, according to the period of quotation, which results in price fluctuations recorded through revenues until the date of settlement, which also results in an embedded derivative that is required to be separated from the main contract.
