Revenue Recognition	REVENUE RECOGNITION The vast majority of the Company’s revenue is derived from contracts which are based upon a customer ordering its products. While there may be master agreements, the contract is only established when the customer’s order is accepted by the Company. The Company accounts for a contract, which may be verbal or written, when it is approved and committed by both parties, the rights of the parties are identified along with payment terms, the contract has commercial substance and collectability is probable. The Company evaluates the transaction for distinct performance obligations, which are the sale of its products to customers. Since its products are commodity market-priced, the sales price is representative of the observable, standalone selling price. Each performance obligation is recognized based upon a pattern of recognition that reflects the transfer of control to the customer at a point in time, which is upon destination (customer location or port of destination), and depicts the transfer of control and recognition of revenue. There are instances of customer pick-up at the Company’s facilities, in which case control transfers to the customer at that point and the Company recognizes revenue. The Company’s performance obligations are typically fulfilled within days to weeks of the acceptance of the order. The Company makes judgments regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from revenue and cash flows with customers. Determination of a contract requires evaluation and judgment along with the estimation of the total contract value and if any of the contract value is constrained. Due to the nature of our business, there is minimal variable consideration, as the contract is established at the acceptance of the order from the customer. When applicable, variable consideration is estimated at contract inception and updated on a regular basis until the contract is completed. Allocating the transaction price to a specific performance obligation based upon the relative standalone selling prices includes estimating the standalone selling prices including discounts and variable consideration. Contract Costs The Company can incur incremental costs to obtain or fulfill a contract such as broker expenses that are not expected to be recovered. The amortization period for such expenses is less than one year; therefore, the costs are expensed as incurred. Taxes The Company excludes all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the entity from a customer (for example, sales, use, value added and some excise taxes) from the transaction price. Contract Balances The Company receives payment from customers based on terms established with the customer. Payments are typically due within 14 to 30 days of delivery. Revenue contract liabilities relate to payments received in advance of satisfying the performance under the customer contract. The revenue contract liabilities relate to customer prepayments and the advanced consideration, such as cash, received from governmental agency contracts for which performance obligations to the end customer have not been satisfied.
Accounts Receivable	Accounts Receivable The Company records accounts receivable when revenue is recognized. We record an allowance for credit losses, reducing our receivables balance to an amount we estimate is collectible from our customers. Estimates used in determining the allowance for credit losses are based on historical collection experience, current trends, aging of accounts receivable and periodic credit evaluations of our customers’ financial condition. We write off accounts receivable when it becomes apparent, based upon age or customer circumstances, that such amounts will not be collected. Generally, the Company does not require collateral for its accounts receivable.

In November 2024, the FASB issued ASU 2024-03, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40), which requires additional disclosures for certain costs and expenses to help investors better understand major components of an entity’s income statement. The guidance requires additional disclosures for costs and expenses such as purchases of inventory, employee compensation, depreciation, and intangible asset amortization. The provisions of the new guidance will be effective for annual reporting years beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. The Company plans to adopt this guidance as it becomes effective and is assessing the impacts on our Consolidated Financial Statements.

Revenue Recognition

REVENUE RECOGNITION

The vast majority of the Company’s revenue is derived from contracts which are based upon a customer ordering its products. While there may be master agreements, the contract is only established when the customer’s order is accepted by the Company. The Company accounts for a contract, which may be verbal or written, when it is approved and committed by both parties, the rights of the parties are identified along with payment terms, the contract has commercial substance and collectability is probable.

The Company evaluates the transaction for distinct performance obligations, which are the sale of its products to customers. Since its products are commodity market-priced, the sales price is representative of the observable, standalone selling price. Each performance obligation is recognized based upon a pattern of recognition that reflects the transfer of control to the customer at a point in time, which is upon destination (customer location or port of destination), and depicts the transfer of control and recognition of revenue. There are instances of customer pick-up at the Company’s facilities, in which case control transfers to the customer at that point and the Company recognizes revenue. The Company’s performance obligations are typically fulfilled within days to weeks of the acceptance of the order.

The Company makes judgments regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from revenue and cash flows with customers. Determination of a contract requires evaluation and judgment along with the estimation of the total contract value and if any of the contract value is constrained. Due to the nature of our business, there is minimal variable consideration, as the contract is established at the acceptance of the order from the customer. When applicable, variable consideration is estimated at contract inception and updated on a regular basis until the contract is completed. Allocating the transaction price to a specific performance obligation based upon the relative standalone selling prices includes estimating the standalone selling prices including discounts and variable consideration.

Contract Costs

The Company can incur incremental costs to obtain or fulfill a contract such as broker expenses that are not expected to be recovered. The amortization period for such expenses is less than one year; therefore, the costs are expensed as incurred.

Taxes

The Company excludes all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the entity from a customer (for example, sales, use, value added and some excise taxes) from the transaction price.

Contract Balances

The Company receives payment from customers based on terms established with the customer. Payments are typically due within 14 to 30 days of delivery. Revenue contract liabilities relate to payments received in advance of satisfying the performance under the customer contract. The revenue contract liabilities relate to customer prepayments and the advanced consideration, such as cash, received from governmental agency contracts for which performance obligations to the end customer have not been satisfied.

Accounts Receivable

The Company records accounts receivable when revenue is recognized. We record an allowance for credit losses, reducing our receivables balance to an amount we estimate is collectible from our customers. Estimates used in determining the allowance for credit losses are based on historical collection experience, current trends, aging of accounts receivable and periodic credit evaluations of our customers’ financial condition. We write off accounts receivable when it becomes apparent, based upon age or customer circumstances, that such amounts will not be collected. Generally, the Company does not require collateral for its accounts receivable.
