Summary of Significant Accounting Policies [Abstract] |
Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, Pro-Dex Astromec, Inc. (Note 3), and Pro-Dex Management, Inc., a non-operating subsidiary. All significant inter-company accounts and transactions have been eliminated.
Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America.
Revenue Recognition | Revenue Recognition Revenue on product sales is recognized upon shipment to the customer when risk of loss and title transfer to the customer and all other conditions required by GAAP, as promulgated by the Financial Accounting Standards Board (“FASB”) in Accounting Standards Codification (“ASC”) Section 605 (formerly Staff Accounting Bulletin No. 104, Revenue Recognition), have been satisfied. Returns of our product for credit are minimal; accordingly, we do not establish a reserve for product returns at the time of sale.
Warranties | Warranties Certain of our products are sold with a warranty that provides for repairs or replacement of any defective parts for a period, generally one year, after the sale. At the time of the sale, we accrue an estimate of the cost of providing the warranty based on prior experience with such factors as return rates and repair costs, which factors are reviewed quarterly. The warranty accrual is based on historical costs of warranty repairs and expected future identifiable warranty expenses, and is included in accrued expenses in the accompanying consolidated balance sheets. Warranty expenses are included in cost of sales in the accompanying consolidated statements of operations. Changes in estimates to previously established warranty accruals result from current period updates to assumptions regarding repair costs and warranty return rates, and are included in current period warranty expense.
Cash and Cash Equivalents | Cash and Cash Equivalents We consider all highly liquid investments with an original maturity of ninety days or less to be cash equivalents. We had not invested any of our cash in cash equivalents during fiscal years 2012 or 2011.
Accounts Receivable | Accounts Receivable Trade receivables are stated at their original invoice amounts, less an allowance for doubtful portions of such accounts. Management determines the allowance for doubtful accounts based on facts and circumstances related to specific accounts and on historical experience related to the age of accounts. Trade receivables are written off when deemed uncollectible. Recoveries of trade receivables previously reserved are offset against the allowance when received.
Inventories | Inventories Inventories are stated at the lower of cost (first-in, first-out method) or market value. Reductions to estimated market value are recorded, and charged to cost of sales, when indicated based on a formula that compares on-hand quantities to estimated demand over the ensuing 12 months from the measurement date.
Property, Plant, Equipment and Leasehold Improvements, and Real Estate Held For Sale | Property, Plant, Equipment and Leasehold Improvements, and Real Estate Held For Sale Property, plant, equipment and leasehold improvements are recorded at historical cost and depreciation is provided using the straight-line method over the following periods:
Building |  | 39 years
Leasehold improvement |  | Shorter of the lease term or the asset’s estimated useful life
Equipment |  | Three to ten years
As more fully described in Note 3, on February 27, 2012, we completed the sale of our fractional horsepower motor product line, operating under the name Pro-Dex Astromec (“Astromec”), consisting primarily of inventories and equipment. On that date we also reclassified the land and building we own, which comprise the facility in which Astromec operated, to real estate held for sale. The carrying value of real estate held for sale is based on its historical cost at the date on which such assets were classified as held for sale (Note 3), and is not subject to depreciation.
Long-Lived Assets | Long-Lived Assets We review the recoverability of the carrying amount of long-lived assets, such as property, plant, equipment and leasehold improvements, and real estate held for sale, when events or changes in circumstances occur that indicate such carrying values may not be recoverable. With respect to property, plant, equipment and leasehold improvements, carrying values are compared to expected future pre-tax cash flows, undiscounted and without interest charges, of related operations. With respect to real estate held for sale, the carrying value is compared to the estimated net proceeds from sale of the real estate. Impairment losses are recognized in instances where carrying values are less than such expected future cash flows or net proceeds from sale, as applicable.
Income Taxes | Income Taxes We recognize deferred tax assets and liabilities for temporary differences between the financial reporting basis and the tax basis of our assets and liabilities along with net operating loss and tax credit carryovers. Deferred tax assets at June 30, 2012 and 2011 consisted primarily of basis differences related to research and development tax credit utilization, intangible assets, accrued expenses and inventories. Significant management judgment is required in determining our provision for income taxes and the recoverability of our deferred tax assets. Such determination is based on our historical taxable income, with consideration given to our estimates of future taxable income and the periods over which deferred tax assets will be recoverable. We record a valuation allowance against deferred tax assets to reduce the net carrying value to an amount that we believe is more likely than not to be realized. When we establish or reduce the valuation allowance against deferred tax assets, the provision for income taxes will increase or decrease, respectively, in the period such determination is made.
Shipping and Handling | Shipping and Handling Payments from customers for shipping and handling are included in net sales. Shipping expenses, consisting primarily of payments made to freight companies, are included in cost of sales.
Concentration of Credit Risk | Concentration of Credit Risk Financial instruments that potentially subject us to credit risk consist principally of cash and trade receivables. The Company places its cash with major financial institutions. At June 30, 2012 and 2011, and at various times throughout the fiscal years then ended, we had deposits in excess of federally insured limits. Credit sales are made to original equipment manufacturers and resellers throughout the world, and sales to such customers account for a substantial portion of our trade receivables. While such receivables are not collateralized, we evaluate their collectability based on several factors including customers’ payment histories.
Compensation Plans | Compensation Plans Share-Based Plans We recognize compensation expense for all share-based awards made to employees and directors. The fair value of share-based awards is estimated at the grant date using the Black-Scholes option-pricing model. The portion that is ultimately expected to vest is recognized as compensation cost over the requisite service period using the straight-line single option method. The determination of fair value using the Black-Scholes model is affected by our stock price as well as assumptions regarding a number of complex and subjective variables, including expected stock price volatility, risk-free interest rate, expected dividends, projected employee stock option exercise behaviors and forfeitures. We estimate stock price volatility based on two factors: (a) the measurement date (typically the grant date) and (b) the expected life of the option, which we calculate using the Staff Accounting Bulletin No. 107 simplified method. Cash-Based Plans Our Annual Incentive Plan (“AIP”) provides annual cash-based incentive opportunities for our key employees based upon the attainment of certain performance goals. Compensation expense is recognized in the year in which awards under the terms of the AIP are earned. Our Long-Term Incentive Plan (“LTIP”) provides incentive opportunities to our executives and other key employees. LTIP awards, if any, are conditioned on attainment of certain performance goals for one or more fiscal years as ratified by our Board of Directors. The amount of awards are defined in the LTIP as a percentage, ranging from 12.5% to 75%, of the employee’s base compensation at the award date, which amount is then divided by the per share market price of our common stock at the award date in order to determine the number of common shares to be awarded. Accordingly, LTIP awards, although paid in shares of our common stock, are dollar-based and accrued as liabilities when their payment becomes probable.
Use of Estimates | Use of Estimates The preparation of financial statements 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. Our operations are affected by numerous factors including market acceptance of our products, changes in technologies, and new laws, government regulations and policies. We cannot predict what impact, if any, the occurrence of these or other events might have on our operations. Significant estimates and assumptions made by management include, but are not limited to: revenue recognition, the allowance for doubtful accounts, accrued warranty expense, inventory valuation, the carrying value of long-lived assets, and the recovery of deferred income tax assets.
Basic and Diluted Per Share Information | Basic and Diluted Per Share Information Basic per share amounts are computed on the basis of the weighted-average number of common shares outstanding during each period presented. Diluted per share amounts assume the exercise of all potential common stock equivalents, consisting solely of options to purchase common stock as discussed in Note 9, unless the effect of such exercise is to increase income, or decrease loss, per common share.
Fair Value Measurements | Fair Value Measurements Fair value is measured based on the prices 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. Fair value measurements are based on a three-tier hierarchy that prioritizes the inputs used to measure fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions. Cash and cash equivalents: The carrying value of cash and cash equivalents is considered to be representative of their fair values based on the short term nature of these instruments. As such, cash and cash equivalents are classified within Level 1 of the valuation hierarchy. Real estate held for sale: The land and building comprising this asset category are classified within Level 2 of the valuation hierarchy for purposes of evaluating carrying value. Although the methods above may produce a fair value calculation that may not be indicative of the net realizable value or reflective of future fair values, the Company believes its valuation methods are appropriate.
Research and Development | Research and Development Research and development costs support the development of our product line platforms, and are charged to expense as incurred.
Advertising | Advertising Advertising costs are charged to selling expense as incurred and amounted to $358,000 and $397,000 for the years ended June 30, 2012 and 2011, respectively.
