Segment Reporting Disclosure [Text Block] | Note 6. Business Segments and Sales of Products We discover, acquire and develop mines and other mineral interests and produce and market concentrates, carbon material and doré containing silver, gold, lead and zinc. We are currently organized and managed in five segments, which represent our operating units: the Greens Creek unit, the Lucky Friday unit, the Casa Berardi unit, the San Sebastian unit, and the Nevada Operations unit. General corporate activities not associated with operating units and their various exploration activities, as well as discontinued operations and idle properties, are presented as “other.” Interest expense, interest income and income taxes are considered general corporate items, and are not allocated to our segments. The following tables present information about our reportable segments for the three months ended March 31, 2020 and 2019 (in thousands):

Our products consist of metal concentrates and carbon material, which we sell to custom smelters, brokers and third-party processors, and unrefined bullion bars (doré), which may be sold as doré or further refined before sale to precious metals traders. Revenue is recognized upon the completion of the performance obligations and transfer of control of the product to the customer. For sales of metals from refined doré, which we currently have at our Casa Berardi, San Sebastian and Nevada Operations units, the performance obligation is met, the transaction price is known, and revenue is recognized at the time of transfer of control of the agreed-upon metal quantities to the customer by the refiner. 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 sales of carbon material, the performance obligation is met, the transaction price is known, and revenue is recognized generally at the time of arrival at the customer's facility. 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) legal title is transferred to the customer, 2) the customer has accepted the parcel and obtained the ability to realize all of the benefits from the product, 3) the concentrate content specifications are known, have been communicated to the customer, and the customer has the significant risks and rewards of ownership of it, 4) it is very unlikely a concentrate parcel from Greens Creek will be rejected by a customer upon physical receipt, and 5) we have the right to payment for the parcel. 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 specified in the frame contracts and/or can be renegotiated as part of annual amendments to the frame contract. We have determined parcel shipments represent individual performance obligations satisfied at a point in time when control of the shipment is transferred to the customer. 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 concentrate parcel will occur. As such, we use the expected value method to price the parcels until the final settlement date occurs, at which time the final transaction price is known. At March 31, 2020, metals contained in concentrate sales and exposed to future price changes totaled 2.1 million ounces of silver, 6,602 ounces of gold, 11,376 tons of zinc, and 3,721 tons of lead. However, as discussed in Note 11, we seek to mitigate the risk of negative price adjustments by using financially-settled forward and put option contracts for some of our sales. 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. Charges are estimated by us upon shipment of concentrates based on contractual terms, and actual charges typically do not vary materially from our estimates. Costs charged by customers include fixed treatment and refining costs per ton of concentrate and may include price escalators which allow the customers to participate in the increase of lead and zinc prices above a negotiated baseline. Costs for shipping concentrates to customers are recorded to cost of sales as incurred. Sales of metal concentrates and metal products are made principally to custom smelters, brokers, third-party processors and metals traders. The percentage of sales contributed by each segment is reflected in the following table:

Sales of products for the first three months of 2020 and 2019 included net gains of $1.7 million and net losses of $2.5 million, respectively, on financially-settled forward and put option contracts for silver, gold, lead and zinc contained in our sales. See Note 11 for more information. Sales of products to significant customers as a percentage of total sales were as follows for the three-month periods ended March 31, 2020 and 2019:
|  | Three Months Ended March 31, |
|  | 2020 |  |  | 2019 |
CIBC |  |  | 30 | % |  |  | 16 | %
Korea Zinc |  |  | 19 | % |  |  | 20 | %

Teck Metals Ltd. |  |  | 2 | % |  |  | 15 | %
Trafigura |  |  | — | % |  |  | 12 | %
Our trade accounts receivable balance related to contracts with customers was $6.1 million at March 31, 2020 and $12.0 million at December 31, 2019, and included no allowance for doubtful accounts. We have determined our contracts do not include a significant financing component. For doré sales and sales of metal from doré, payment is received at the time the performance obligation is satisfied. Payment for carbon sales is received within a relatively short period of time after the performance obligation is satisfied. The amount of consideration for concentrate sales is variable, and we receive payment for a significant portion of the estimated value of concentrate parcels within a relatively short period of time after the performance obligation is satisfied. We do not incur significant costs to obtain contracts, nor costs to fulfill contracts which are not addressed by other accounting standards. Therefore, we have not recognized an asset for such costs as of March 31, 2020 or December 31, 2019.
