Commitments and Contingencies Disclosure [Text Block]	Note 4. General We follow GAAP guidance in determining our accruals and disclosures with respect to loss contingencies, and evaluate such accruals and contingencies for each reporting period. Accordingly, estimated losses from loss contingencies are accrued by a charge to income when information available prior to issuance of the financial statements indicates that it is probable that a liability could be incurred and the amount of the loss can be reasonably estimated. Legal expenses associated with the contingency are expensed as incurred.

For sales of doré, the performance obligation is met, the transaction price is known, and revenue is recognized at the time of transfer of title and control of the doré containing the agreed-upon metal quantities to the customer. Refining, selling and shipping costs related to sales of doré and metals from doré are recorded to cost of sales as incurred. For concentrate sales, which we currently have at our Greens Creek and Lucky Friday units, the performance obligation is met, the transaction price can be reasonably estimated, and revenue is recognized generally at the time of shipment. Concentrates sold at our Lucky Friday unit typically leave the mine and are received by the customer within the same day. However, there is a period of time between shipment of concentrates from our Greens Creek unit and their physical receipt by the customer, and judgment is required in determining when control has been transferred to the customer for those shipments. We have determined the performance obligation is met and title is transferred to the customer upon shipment of concentrate parcels from Greens Creek because, at that time, 1 2 3 4 5 Judgment is also required in identifying the performance obligations for our concentrate sales. Most of our concentrate sales involve “frame contracts” with smelters that can cover multiple years and specify certain terms under which individual parcels of concentrates are sold. However, some terms are not The consideration we receive for our concentrate sales fluctuates due to changes in metals prices between the time of shipment and final settlement with the customer. However, we are able to reasonably estimate the transaction price for the concentrate sales at the time of shipment using forward prices for the month of settlement, and previously recorded sales and accounts receivable are adjusted to estimated settlement metals prices until final settlement with the customer. Also, it is unlikely a significant reversal of revenue for any one June 30, 2019, Note 11 Sales and accounts receivable for concentrate shipments are recorded net of charges for treatment, refining, smelting losses, and other charges negotiated by us with the customers, which represent components of the transaction price.

Our non-current available for sale securities consist of marketable equity securities of companies in the mining industry which are valued using quoted market prices for each security. Trade accounts receivable include amounts due to us for shipments of concentrates, doré and metals sold from doré to customers. Revenues and the corresponding accounts receivable for sales of metals products are recorded when title and risk of loss transfer to the customer (generally at the time of ship loading, or at the time of customer arrival for trucked products). Sales of concentrates are recorded using estimated forward prices for the anticipated month of settlement applied to our estimate of payable metal quantities contained in each shipment. Sales are recorded net of estimated treatment and refining charges, which are also impacted by changes in metals prices and quantities of contained metals. We estimate the prices at which sales of our concentrates will be settled due to the time elapsed between shipment and final settlement with the customer. Receivables for previously recorded concentrate sales are adjusted to reflect estimated forward metals prices at the end of each period until final settlement by the customer. We obtain the forward metals prices used each period from a pricing service. Changes in metals prices between shipment and final settlement result in changes to revenues previously recorded upon shipment. The embedded derivative contained in our concentrate sales is adjusted to fair market value through earnings each period prior to final settlement. We use financially-settled forward contracts to manage exposure to changes in the exchange rate between USD and CAD and MXN, and the impact on CAD- and MXN-denominated operating costs incurred at our Casa Berardi and San Sebastian units (see Note 11 We use financially-settled forward contracts to manage the exposure to changes in prices of silver, gold, zinc and lead contained in our concentrate shipments that have not Note 11 not Our Senior Notes, which were recorded at their carrying value of $504.1 million, net of unamortized initial purchaser discount at June 30, 2019, June 30, 2019. 1 Note 9

A sensitivity analysis was performed, and decreasing the weighted-average gold price assumption to below approximately $1,280 per ounce, with all other variables held constant, would have resulted in estimated undiscounted future cash flows that were less than the carrying value of the Nevada assets as of June 30, 2019. may not first 2021. no June 30, 2019 See Part II, Item 1A
