Significant Accounting Policies [Text Block] | 2. Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements include the accounts of Yunhong CTI Ltd., its wholly owned subsidiary CTI Supply, Inc. and former wholly owned subsidiary CTI Balloon Ltd and its former majority owned subsidiaries, Flexo Universal and CTI Europe. All significant intercompany accounts and transactions have been eliminated upon consolidation. As discussed in Note 23 Discontinued Operations, effective in 2019, the Company determined that it was exiting CTI Balloons Limited and CTI Europe, and during 2021 sold its interest in Flexo Universal. Accordingly, the operations of these entities are classified as discontinued operations in these financial statements. Variable Interest Entities The determination of whether or not to consolidate a variable interest entity under U.S. GAAP requires a significant amount of judgment concerning the degree of control over an entity by its holders of variable interest. To make these judgments, management has conducted an analysis of the relationship of the holders of variable interest to each other, the design of the entity, the expected operations of the entity, which holder of variable interests is most “closely associated” to the entity and which holder of variable interests is the primary beneficiary required to consolidate the entity. Upon the occurrence of certain events, management reviews and reconsiders its previous conclusion regarding the status of an entity as a variable interest entity. Foreign Currency Translation The financial statements of foreign subsidiaries are translated into U.S. dollars using the exchange rate at each balance sheet date for assets and liabilities, the historical exchange rate for stockholders’ equity, and a weighted average exchange rate for each period for revenues and expenses. Translation adjustments are recorded in accumulated other comprehensive income (loss) as the local currencies of the subsidiaries are the functional currencies. Foreign currency transaction gains and losses are recognized in the period incurred and are included in the consolidated statements of operations. Use of Estimates In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the amounts reported of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period in the financial statements and accompanying notes. Actual results may differ from those estimates. The Company’s significant estimates include valuation allowances for doubtful accounts, inventory valuation, deferred tax assets, goodwill and intangible asset valuation, leasehold assets and liabilities, Preferred Stock deemed dividends and beneficial conversion feature values, and assumptions used as inputs in the Black-Scholes option-pricing model. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, demand deposits and short-term investments with original maturities of three months or less. Accounts Receivable Trade receivables are carried at original invoice amount less an estimate for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Management determines the allowance for doubtful accounts by identifying troubled accounts, evaluating the individual customer receivables through consideration of the customer’s financial condition, credit history and current economic conditions and use of historical experience applied to an aging of accounts. A trade receivable is considered to be past due if any portion of the receivable balance is outstanding for a period over the customer’s normal terms. Trade receivables are written off when deemed uncollectible. Recoveries of trade receivables previously written off are recorded when received. Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined using standard costs which approximates costing determined on a first-in, first-out basis, to reflect the actual cost of production of inventories. Production costs of work in process and finished goods include material, labor and overhead. Inventory is not recorded in excess of net realizable value. Property, Plant and Equipment Property and equipment are stated at cost. Expenditures for maintenance and repairs are charged to operations as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized on a straight-line method over the lesser of the estimated useful life or the lease term. The estimated useful lives range as follows:
|  | (in years) |
Building |  |  | 25 | - | 30 |
Machinery and equipment |  |  | 3 | - | 15 |
Projects that prolong the life and increase efficiency of machinery |  |  | 3 | - | 5 |
Light Machinery |  |  | 5 | - | 10 |
Heavy Machinery |  |  | 10 | - | 15 |
Office furniture and equipment |  |  | 5 | - | 8 |
Intellectual Property |  |  | 9 | - | 15 |
Leasehold improvements |  |  | 5 | - | 8 |
Furniture and equipment at customer locations |  |  | 1 | - | 3 |
Light machinery consists of forklifts, scissor lifts, and other warehouse machinery. Heavy machinery consists of production equipment including laminating, printing and converting equipment. Projects in process represent those costs capitalized in connection with construction of new assets and/or improvements to existing assets including a factor for interest on funds committed to projects in process of $220,000 and $71,000 for the years ended December 31, 2021 and 2020, respectively. Upon completion, these costs are reclassified to the appropriate asset class. Stock-Based Compensation The Company has stock-based incentive plans which may grant stock option, restricted stock and unrestricted stock awards. The Company recognizes stock-based compensation expense based on the grant date fair value of the award and the related vesting terms. The fair value of stock-based awards is determined using the Black-Scholes model, which incorporates assumptions regarding the risk-free interest rate, expected volatility, expected option life, and dividend yield. See Note 18 for additional information. Fair Value Measurements Current professional accounting guidance applies to all assets and liabilities that are being measured and reported on a fair value basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal or most advantageous market. The requirements prescribe a fair value hierarchy that has three levels of inputs, both observable and unobservable, with use of the lowest possible level of input to determine fair value. A Level 1 input includes a quoted market price in an active market or the price of an identical asset or liability. Level 2 inputs are market data other than Level 1 inputs that are observable either directly or indirectly including quoted market prices for similar assets or liabilities, quoted market prices in an inactive market, and other observable information that can be corroborated by market data. Level 3 inputs are unobservable and corroborated by little or no market data. The carrying value amounts of the Company’s cash and cash equivalents, accounts and notes receivable, accounts payable and other current liabilities are reasonable estimates of their fair values due to the short-term nature of these instruments. The fair value of business segments (as needed for purposes of determining indications of impairment to the carrying value of goodwill) is determined using an average of valuations based on market multiples and discounted cash flows, and consideration of our market capitalization. See Note 5 for further discussion. Valuation of Long Lived Assets The Company evaluates whether events or circumstances have occurred which indicate that the carrying amounts of long-lived assets (principally property, plant and equipment) may be impaired or not recoverable. The significant factors that are considered that could trigger an impairment review include: changes in business strategy, market conditions, or the manner of use of an asset; underperformance relative to historical or expected future operating results; and negative industry or economic trends. In evaluating an asset for possible impairment, management estimates that asset’s future undiscounted cash flows and appraised values to measure whether the asset is recoverable. The Company measures the impairment based on the projected discounted cash flows of the asset over its remaining life. Deferred Financing Costs Deferred financing costs are amortized over the term of the loan. Upon a refinancing, existing unamortized deferred financing costs are expensed. Income Taxes The Company accounts for income taxes using the liability method. As such, deferred income taxes reflect the net tax effects of temporary differences between carrying amounts of assets and liabilities for financial reporting purposes and the amount used for income tax purposes. Deferred tax assets and liabilities are measured using enacted tax rates expected to be in effect when the anticipated reversal of these differences is scheduled to occur. Deferred tax assets are reduced by a valuation allowance when management cannot determine, in its opinion, that it is more likely than not that the Company will recover that recorded value of the deferred tax asset. The Company is subject to U.S. Federal, state and local taxes as well as foreign taxes in Mexico (through October 2021). U.S. income tax expense and foreign withholding taxes are provided on remittances of foreign earnings and on unremitted foreign earnings that are not indefinitely reinvested. Unrecognized tax benefits are accounted for as required by U.S. GAAP which prescribes a more likely than not threshold for financial statement presentation and measurement of a tax position taken or expected to be taken in a tax return. See Note 11 for further discussion. Revenue Recognition On January 1, 2018, we adopted Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers using the modified retrospective method. The adoption of ASC 606 did not have a material impact on our consolidated financial position or results of operations, as our revenue arrangements generally consist of a single performance obligation to transfer promised goods at a fixed price. Net sales include revenues from sales of products and shipping and handling charges, net of estimates for product returns. Revenue is measured at the amount of consideration the Company expects to receive in exchange for the transferred products. Revenue is recognized at the point in time when we transfer the promised products to the customer and the customer obtains control over the products. The Company recognizes revenue for shipping and handling charges at the time the goods are shipped to the customer, and the costs of outbound freight are included in cost of sales, as we have elected the practical expedient included in ASC 606. In most cases, the Company has a single product delivery performance obligation. Accrued product returns are estimated based on historical data and evaluation of current information. The Company provides for product returns based on historical return rates. While we incur costs for sales commissions to our sales employees and outside agents, we recognize commission costs concurrent with the related revenue, as the amortization period is less than one year and we have elected the practical expedient included in ASC 606. We do not incur incremental costs to obtain contracts with our customers. Our product warranties are assurance-type warranties, which promise the customer that the products are as specified in the contract. Therefore, the product warranties are not a separate performance obligation and are accounted for as described herein. Sales taxes assessed by governmental authorities are accounted for on a net basis and are excluded from net sales. A disaggregation of product net sales is presented in Note 20. Research and Development The Company conducts product development and research activities which include (i) creative product development and (ii) engineering. During the years ended December 31, 2021 and 2020, research and development activities totaled $206,000 and $317,000, respectively. Advertising Costs The Company expenses advertising costs as incurred.
