| Consolidation | Consolidation - The accompanying consolidated financial statements of Sono-Tek Corporation, a New York corporation (the “Company”), include the accounts of the Company and its wholly owned subsidiaries, Sono-Tek Cleaning Systems Inc. and Sono-Tek Industrial Park, LLC. Sono-Tek Cleaning Systems, Inc., a New Jersey Corporation (“SCS”), ceased operations during the Fiscal Year Ended February 28, 2002. Sono-Tek Industrial Park, LLC (“SIP”), operates as a real estate holding company for the Company’s real estate operations. |
| Earnings Per Share | Earnings Per Share - Basic earnings per share (“EPS”) is computed by dividing net income by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. |
| Equipment, Furnishings and Leasehold Improvements | Equipment, Furnishings and Leasehold Improvements – Equipment, furnishings and leasehold improvements are stated at cost. Depreciation of equipment and furnishings is computed by use of the straight-line method based on the estimated useful lives of the assets, which range from three to five years. |
| Fair Value of Financial Instruments | Fair Value of Financial Instruments - The Company follows the guidance in the “Fair Value Measurements and Disclosure Topic” of the Accounting Standards Codification for assets and liabilities measured at fair value on a recurring basis. This guidance establishes a common definition for fair value to be applied to existing generally accepted accounting principles that require the use of fair value measurements, establishes a framework for measuring fair value and expands disclosure about such fair value measurements. The guidance defines fair value 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. Additionally, the guidance requires the use of valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized below: |
|
| Level 1: Quoted prices in active markets. |
|
| Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data. |
|
| Level 3: Unobservable inputs for which there is little or no market data, which require the use of the reporting entity’s own assumptions. |
|
| The fair values of financial assets of the Company were determined using the following categories at February 28, 2015 and 2014, respectively: |
|
| | Quoted Prices in Active Markets | |
| | (Level 1) | |
| | February 28, | |
| | 2015 | | | 2014 | |
| | | | | | |
| Marketable Securities | | $ | 1,652,485 | | | $ | 630,794 | |
|
| Marketable Securities include mutual funds of $1,652,485 and $630,794, that are considered to be highly liquid and easily tradeable as of February 28, 2015 and 2014, respectively. These securities are valued using inputs observable in active markets for identical securities and are therefore classified as Level 1 within the Company’s fair value hierarchy. |
| Income Taxes | Income Taxes - The Company accounts for income taxes under the asset and liability method. Under this method, deferred income taxes are recognized for the tax consequences of "temporary differences" by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities. If it is more likely than not that some portion or all of a deferred tax asset will not be realized, a valuation allowance is recognized. |
| Intangible Assets | Intangible Assets -Include costs of patent applications which are deferred and charged to operations over seventeen years for domestic patents and twelve years for foreign patents. The accumulated amortization of patents is $116,804 and $105,585 at February 28, 2015 and 2014, respectively. Annual amortization expense of such intangible assets is expected to be $9,600 per year for the next five years. |
| Inventories | Inventories - Inventories are stated at the lower of cost or market. Cost is determined using the first-in, first-out (FIFO) method for raw materials, subassemblies and work-in-progress and the specific identification method for finished goods. |
| Land and Buildings | Land and Buildings – Land and buildings are stated at cost. Buildings are being depreciated by use of the straight-line method based on an estimated useful life of forty years. |
| Long-Lived Assets | Long-Lived Assets - The Company periodically evaluates the carrying value of long-lived assets, including intangible assets, when events and circumstances warrant such a review. The carrying value of a long-lived asset is considered impaired when the anticipated undiscounted cash flow from such asset is separately identifiable and is less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair market value of the long-lived asset. Fair market value is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risk involved. |
| Management Estimates | Management Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. |
| New Accounting Pronouncements | New Accounting Pronouncements- All new accounting pronouncements issued but not yet effective have been deemed to be not applicable to the Company. Hence, the adoption of these new accounting pronouncements once effective are not expected to have an impact on the Company. |
| Product Warranty | Product Warranty - Expected future product warranty expense is recorded when the product is sold. |
| Reclassifications | Reclassifications – Where appropriate, prior year’s financial statements reflect reclassifications to conform to the current year’s presentation. |
| Recognition of Revenue | Recognition of Revenue – Sales are recorded at the time title passes to the customer, which, based on shipping terms, generally occurs when the product is shipped to the customer. Based on prior experience, the Company reasonably estimates its sales returns and warranty reserves. Sales are presented net of discounts and allowances. Discounts and allowances are determined when a sale is negotiated. The Company does not grant its customers or independent representatives the ability to return equipment nor does it grant price adjustments after a sale is complete. |
| Research and Product Development Expenses | Research and Product Development Expenses - Research and product development expenses represent engineering and other expenditures incurred for developing new products, for refining the Company's existing products and for developing systems to meet unique customer specifications for potential orders or for new industry applications and are expensed as incurred. |
| Shipping and Handling Costs | Shipping and Handling Costs – Shipping and handling costs are included in cost of sales in the accompanying consolidated statements of operations. |
