Organization, Consolidation and Presentation of Financial Statements [Abstract]

Revenue Recognition

We recognize revenue when performance obligations under the terms of the contracts with customers are satisfied. Our performance obligation generally consists of the promise to sell finished products to wholesalers, distributors and retailers or consumers and our obligations have an original duration of one year or less. Control of the finished products are transferred upon shipment to, or receipt at, customers' locations, as determined by the specific terms of the contract. We have completed our performance obligation when control is transferred and we recognize revenue accordingly.

We have an unconditional right to consideration under the payment terms specified in the contract upon completion of the performance obligation. We may require certain customers to provide payment in advance of product shipment. We recorded a liability for these advance payments of $96,000 and $242,000 as of October 31, 2018 and July 31, 2018, respectively. This liability is reported in Other Accrued Expenses on the Condensed Consolidated Balance Sheet. Revenue recognized during the first quarter ended October 31, 2018 that was included in the liability for advance payments at the beginning of the period was $84,000.

We routinely commit to one-time or ongoing trade promotion programs directly with consumers, such as coupon programs, and with customers, such as volume discounts, cooperative marketing and other arrangements. We estimate and accrue the expected costs of these programs. These costs are considered variable consideration under ASC 606, Revenue from Contracts with Customers, and are netted against sales when revenue is recorded. The accruals are based on our best estimate of the amounts necessary to settle future and existing obligations on products sold as of the balance sheet date. To estimate these accruals, we rely on our historical experience of trade spending patterns and that of the industry, current trends and forecasted data.

Selling, General and Administrative Expenses

Selling, general and administrative expenses (“SG&A”) include salaries, wages and benefits associated with staff outside the manufacturing and distribution functions, all marketing related costs, any miscellaneous trade spending expenses not required to be included in net sales, research and development costs, depreciation and amortization related to assets outside the manufacturing and distribution process and all other non-manufacturing and non-distribution expenses.

Trade Receivable

We record an allowance for doubtful accounts based on our historical experience and a periodic review of our accounts receivable, including a review of the overall aging of accounts, consideration of customer credit risk and analysis of facts and circumstances about specific customer accounts. A customer account is determined to be uncollectible when it is probable that a loss will be incurred after we have completed our internal collection procedures, including termination of shipments, direct customer contact and formal demand of payment.

Overburden Removal and Mining Costs

We mine sorbent materials on property that we either own or lease as part of our overall operations. A significant part of our overall mining cost is incurred during the process of removing the overburden (non-usable material) from the mine site, thus exposing the sorbent material used in a majority of our production processes. These stripping costs are treated as a variable inventory production cost and are included in cost of sales in the period they are incurred. We defer and amortize the pre-production overburden removal costs associated with opening a new mine.

Additionally, it is our policy to capitalize the purchase cost of land and mineral rights, including associated legal fees, survey fees and real estate fees. The costs of obtaining mineral patents, including legal fees and drilling expenses, are also capitalized. Pre-production development costs on new mines and any prepaid royalties that may be offset against future royalties due upon extraction of the minerals are also capitalized. All exploration related costs are expensed as incurred.

Reclamation

We perform ongoing reclamation activities during the normal course of our overburden removal. As overburden is removed from a mine site, it is hauled to previously mined sites and is used to refill older sites. This process allows us to continuously reclaim older mine sites and dispose of overburden simultaneously, therefore minimizing the costs associated with the reclamation process.
