Another subsidiary, Torotel Manufacturing Corporation ("TMC"), provided manufacturing services to Torotel Products. TMC ceased activities on December 31, 2012. Torotel specializes in the custom design and manufacture of a wide variety of precision magnetic components, consisting of transformers, inductors, reactors, chokes, toroidal coils, high voltage transformers, dry-type transformers and electro-mechanical assemblies for use in aerospace, industrial and military electronics.

Significant estimates used in preparing these consolidated financial statements include those assumed in computing the carrying value of inventory, the allowance for doubtful accounts receivable, the valuation allowance on deferred income tax assets, and the reserve for warranty costs. Accordingly, actual results could differ from those estimates. Any changes in estimates are recorded in the period in which they become known.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Credit Risk&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash and accounts receivable.

The inputs used to estimate the fair value of long-term debt are considered Level 2 inputs.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Treasury Stock&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;We utilize the weighted average cost method in accounting for treasury stock transactions.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Revenue Recognition&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Revenue is recognized when a fixed price contract or purchase order exists; delivery has occurred; and collection is reasonably assured.

The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our existing accounts receivable. We review the allowance for doubtful accounts on a regular basis, and all past due balances are reviewed individually for collectability. Account balances are charged against the allowance when placed for collection. Recoveries of receivables previously written off are recorded when received. The majority of the customer accounts are considered past due after the invoice becomes older than the customer's credit terms. Interest is not charged on past due accounts.

Cost is determined using a FIFO approximated weighted average cost method of valuation. Our industry is characterized by short-term customer commitments and changes in demand, as well as other market considerations. Provisions for obsolete and excess inventory are based on reviews of inventory usage, quantities on hand and latest product demand information from customers. Inventories are reviewed in detail utilizing a 12-month time horizon. Individual part numbers that have not had any usage or purchases in a 12-month time period and do not have any known usage requirements are categorized as obsolete; individual part numbers having more than a 12-month supply based on the current year's usage are categorized as excess. Once specific inventory has been identified as excess or obsolete, the cost of the identified inventory is fully reserved and the cost of the inventory is not recovered until it is sold. The reserve balance is analyzed for adequacy as part of the inventory review each quarter.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Property, Plant and Equipment&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Property, plant and equipment are carried at cost. Depreciation and amortization are provided in amounts sufficient to relate the costs of depreciable assets to operations primarily using the straight-line method over estimated useful lives of three to five years for equipment and three and a half to twenty years for buildings and improvements.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Cash and Cash Equivalents&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;For purposes of the consolidated statements of cash flows, we consider all short-term investments and demand deposits purchased with original maturity dates of three months or less to be cash.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Income Taxes&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Our annual tax rate is based on our income, statutory tax rates and tax planning opportunities available to us in the various jurisdictions in which we operate. Significant judgment is required in determining our annual tax rate and in evaluating our tax positions. An estimated effective tax rate for a year is applied to our quarterly operating results. In the event there is a significant or unusual item recognized in our quarterly operating results, the tax attributable to that item is separately calculated and recorded at the same time as that item. Tax law requires items to be included in our tax returns at different times than the items are reflected in our financial statements. As a result, our annual tax rate reflected in our financial statements is different than that reported in our tax returns (our cash tax rate). Some of these differences are permanent, such as expenses that are not deductible in our tax return, and some differences reverse over time, such as depreciation expense. These temporary differences create deferred tax assets and liabilities. Deferred tax assets generally represent items that can be used as a tax deduction or credit in our tax returns in future years for which we have already recorded the tax benefit in our income statement. We establish valuation allowances for our deferred tax assets if, based on the available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax liabilities generally represent tax expense recognized in our financial statements for which payment has been deferred, or expense for which we have already taken a deduction in our tax return but have not yet recognized as expense in our financial statements.&amp;#160;The accounting for uncertainty in income taxes requires a more-likely-than-not threshold for financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. If necessary, we record a liability for the difference between the benefit recognized and measured for financial statement purposes and the tax position taken or expected to be taken on our tax return. To the extent that our assessment of such tax positions changes, the change in estimate is recorded in the period in which the determination is made. If applicable in a given year, tax-related interest and penalties are classified as a component of income tax expense.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Advertising Costs&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Advertising costs are expensed as incurred.

A limited warranty is provided for a period of one year which requires us to repair or replace defective products at no cost to the customer.
