SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: | ​ NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: ​ In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13: “Financial Instruments – Credit Losses (Topic 326)”. This amendment includes disclosure requirements that are both quantitative and qualitative in nature. This amendment affects loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. The main purpose of these disclosures is to (1) enable financial statement users to understand the credit risk inherent in a reporting entity’s portfolio, (2) understand how management monitors credit risk, (3) provide insight as to how management develops estimates of expected credit losses, and (4) disclose the changes in these estimates during the reporting period. This ASU was adopted on January 1, 2020. ​ Prior to adopting this ASU, the Company applied an impairment methodology for accounts receivable arising from revenue transactions within the scope of ASC 606 that is consistent with the provision matrix model contemplated in the new standard. In addition, the new disclosure requirements do not apply to such trade receivables because the collection periods in all cases are less than one year. The Company’s accounts receivable from related parties under common control are excluded from the scope of this ASU. Accordingly, the adoption of this ASU did not have a material impact on the Company’s financial statements or related disclosures. ​ Long-term inventory-Ore stockpiles on leach pads: On January 1, 2020, the Company aligned its capitalization method for its Peruvian and Mexican operations to capitalize based on the allocation of copper content recoverable between ore and leach material. In addition, the inventory consumption is now valued at the average unit cost, instead of the declining percentages of recovery method used previously. As a result of these changes, the value of capitalized material decreased by $48.8 million and the consumption increased by $10.3 million. ​ Management has evaluated ASC 250-10 and considered appropriate guidance to conclude that the above mentioned classified as a change in accounting estimate and therefore should affect accounting books prospectively. Management believes that this new method will result in a more appropriate value of this material. ​ ​
