All significant intercompany accounts and transactions have been eliminated. Events that occurred after December 31, 2016 Use of Estimates The preparation of financial statements in conformity with US generally accepted accounting principles (“US GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses for the reporting period. Actual results could differ from these estimates. Periods Presented All amounts have been rounded to the nearest thousand with the exception of the share data. The Company qualified as a smaller reporting company at the measurement date for determining such qualification during 2016. two two Investments The Company periodically invests a portion of its cash in excess of short-term operating needs in marketable debt and equity securities. These investments are classified as available-for-sale in accordance with US GAAP. The Company does not have any investments in securities that are classified as held-to-maturity or trading. Available-for-sale investments are carried at their fair values using quoted prices in active markets for identical securities, with unrealized gains and losses, net of deferred income taxes, reported as a component of accumulated other comprehensive income (loss). Realized gains and losses, and declines in value deemed to be other-than-temporary on available-for-sale investments, are recognized in net income. The cost of securities sold is based on the specific identification method. Investments that the Company intends to hold for more than one The Company had an investment in non-trading warrants to purchase common stock in a publicly traded entity.

Gains or losses from changes in the fair value of the warrants are recognized in the accompanying statements of income in the period in which they occurred. Accounts Receivable Accounts receivable are recorded at the invoice amount and do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable; however, changes in circumstances relating to accounts receivable may Inventories Inventories include freight-in, materials, labor and overhead costs and are stated at the lower of cost or market. Allowances are recorded for slow-moving, obsolete or unusable inventories.

Property and Equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Property and equipment are depreciated or amortized using the straight-line method over the shorter of the respective useful lives of the assets or the related lease terms as follows: Buildings (years) 25 Machinery and equipment 5 - 15 Office furniture and equipment 2 - 7 Leasehold improvements 4 - 5 Expenditures for renewals and betterments are capitalized, whereas costs of maintenance and repairs are charged to operations in the period incurred.

Transaction gains or losses on foreign currencies are reflected in selling, general and administrative expenses and were not material for the years ended December 31, 2016 2015.

In addition, all sales transactions are in US dollars. The Company’s only foreign currency exposure is with its Canadian branch office. The foreign currency exposure is not material due to the fact that the Company does not manufacture in Canada.

Such costs were not material for the years ended December 31, 2016 2015. Advertising Costs The Company expenses advertising costs as incurred. These costs are included in selling, general and administrative expenses and were $39,000 $37,000 December 31, 2016 2015, Loss Contingencies The outcomes of legal proceedings and claims brought against the Company are subject to uncertainty. An estimated loss from a loss contingency such as a legal proceeding or claim is accrued if it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated. In determining whether a loss should be accrued, we evaluate, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss.
