The facility allows the Company to choose among interest rates at which it may borrow funds. The credit facility is collateralized by substantially all of the domestically located assets of the Company and the Company has pledged 65% of its equity ownership interest in some of its foreign entities. The Company is required to be in compliance with several financial covenants. During the quarter ended October 31, 2013, the Company renewed its senior secured credit facility. The facility was revised to extend the term of the agreement to October 31, 2015.

	On October 31, 2014, the Company and Wells Fargo, N.A. extended the senior secured credit facility to October 31, 2017. Pursuant to the agreement, financial covenants were amended, an unused line fee was added, and the borrowing interest rate was changed. The facility allows the Company to choose among interest rates at which it may borrow funds. The interest rate is the prime rate (effectively 3.25% at October 31, 2014) or LIBOR plus two and one quarter percent (effectively 2.50% at October 31, 2014). Interest is paid monthly. Under the senior secured credit facility, the Company may borrow up to the lesser of (i) $30,000,000 or (ii) an amount equal to the sum of 85% of the receivable borrowing base plus a percentage of the inventory borrowing base. Further, in specific circumstances, the Company is entitled to an over advance of up to $5,000,000; however at no time can the borrowings under the credit facility exceed $30,000,000. As of October 31, 2014, there was a $22,500,000 outstanding balance and $7,500,000 of unused availability under the credit facility agreement.

Critical Accounting Policies	'
	Note F - Critical Accounting Policies

	Management Estimates and Uncertainties - The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates made in preparing the consolidated financial statements include depreciation and amortization periods, the allowance for doubtful accounts, reserves for inventory and valuation of long-lived assets. Actual results could materially differ from these estimates.

	Revenue Recognition - Revenues from sales of the Company's electronic manufacturing services business are recognized when the finished good product is shipped to the customer. In general, and except for consignment inventory, it is the Company's policy to recognize revenue and related costs when the finished goods have been shipped from its facilities, which is also the same point that title passes under the terms of the purchase order. Finished goods inventory for certain customers is shipped from the Company to an independent warehouse for storage or shipped directly to the customer and stored in a segregated part of the customer’s own facility. Upon the customer’s request for finished goods inventory, the inventory is shipped to the customer if the inventory was stored off-site, or transferred from the segregated part of the customer’s facility for consumption or use by the customer. The Company recognizes revenue upon such shipment or transfer. The Company does not earn a fee for such arrangements. The Company from time to time may ship finished goods from its facilities, which is also the same point that title passes under the terms of the purchase order, and invoice the customer at the end of the calendar month. This is done only in special circumstances to accommodate a specific customer. Further, from time to time customers request the Company hold finished goods after they have been invoiced to consolidate finished goods for shipping purposes. The Company generally provides a 90 day warranty for workmanship only, except for products with proprietary design, and does not have any installation, acceptance or sales incentives (although the Company has negotiated longer warranty terms in certain instances). The warranty period for proprietary design varies based on specific design specifications. The Company assembles and tests assemblies based on customers’ specifications. Historically, the amount of returns for workmanship issues has been de minimis under the Company’s standard or extended warranties.

	Inventories - Inventories are valued at the lower of cost or market. Cost is calculated as average cost. In the event of an inventory write-down, the Company records expense to state the inventory at lower of cost or market. The Company establishes inventory reserves for valuation, shrinkage, and excess and obsolete inventory. The Company records provisions for inventory shrinkage based on historical experience to account for unmeasured usage or loss. Actual results differing from these estimates could significantly affect the Company’s inventories and cost of products sold. The Company records provisions for excess and obsolete inventories for the difference between the cost of inventory and its estimated realizable value based on assumptions about future product demand and market conditions. Actual product demand or market conditions could be different than that projected by management.

	Goodwill - Goodwill represents the purchase price in excess of the fair value of assets acquired in business combinations. The Company assesses goodwill for impairment at least annually in the absence of an indicator of possible impairment and immediately upon an indicator of possible impairment. The Company is permitted the option to first assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the fair value of any reporting unit is less than its corresponding carrying value. If, after assessing the totality of events and circumstances, the Company concludes that it is not more likely than not that the fair value of any reporting unit is less than its corresponding carrying value then the Company is not required to take further action. However, if the Company concludes otherwise, then it is required to perform a quantitative impairment test, including computing the fair value of the reporting unit and comparing that value to its carrying value. If the fair value is less than its carrying value, a second step of the test is required to determine if recorded goodwill is impaired. The Company also has the option to bypass the qualitative assessment for goodwill in any period and proceed directly to performing the quantitative impairment test. The Company will be able to resume performing the qualitative assessment in any subsequent period. The Company performed its annual goodwill impairment test as of February 1, 2014 and determined that no impairment existed as of that date.

	Impairment of Long-Lived Assets - The Company reviews long-lived assets, including amortizable intangible assets for impairment. Property, machinery and equipment and finite life intangible assets are reviewed whenever events or changes in circumstances occur that indicate possible impairment. If events or changes in circumstances occur that indicate possible impairment, the Company’s impairment review is based on an undiscounted cash flow analysis at the lowest level at which cash flows of the long-lived assets are largely independent of other groups of its assets and liabilities. This analysis requires management judgment with respect to changes in technology, the continued success of product lines, and future volume, revenue and expense growth rates. The Company conducts annual reviews for idle and underutilized equipment, and reviews business plans for possible impairment. Impairment occurs when the carrying value of the assets exceeds the future undiscounted cash flows expected to be earned by the use of the asset group. When impairment is indicated, the estimated future cash flows are then discounted to determine the estimated fair value of the asset or asset group and an impairment charge is recorded for the difference between the carrying value and the estimated fair value.

	Income Tax - Deferred income tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities, and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred income tax assets to an amount more likely than not to be realized.

	A tax benefit from an uncertain tax position may only be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits.


	Note F - Critical Accounting Policies - Continued

	During the second quarter of fiscal year 2015, the Company received distributions from two of its subsidiaries based in Mexico, Acuna in the amount of $2,041,432 and Tijuana in the amount of $965,394. The U.S. income tax on these distributions of $333,128 was reflected in the Company’s tax provision for the fiscal year ended April 30, 2014. The distribution from the foreign subsidiaries based in Mexico does not change the Company’s intentions to indefinitely reinvest the income from the Company’s foreign subsidiaries.

	During the second quarter of fiscal year 2015, the Company recorded a discrete tax expense of $529,257 related to the inability to realize the tax benefit of a foreign tax credit that was generated in the period. The Company’s estimate of cumulative taxable income during the foreign tax credit carryforward period are insufficient to support that the tax benefit from the foreign tax credit is more likely than not to be realized.

	The Company adjusts its tax liabilities when its judgment changes as a result of the evaluation of new information not previously available. Due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from its current estimate of the tax liabilities. These differences will be reflected as increase or decreases to income tax expense in the period in which they are determined.

	New Accounting Standards:

	In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360)." ASU 2014-08 amends the requirements for reporting discontinued operations and requires additional disclosures about discontinued operations. Under the new guidance, only disposals representing a strategic shift in operations or that have a major effect on the Company's operations and financial results should be presented as discontinued operations. This new accounting guidance is effective for annual periods beginning after December 15, 2014. The Company is currently evaluating the impact of adopting ASU 2014-08 on the Company's results of operations or financial condition.

	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." This ASU is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. This ASU is effective for annual reporting periods beginning after December 15, 2016 and early adoption is not permitted. Accordingly, we will adopt this ASU on May 1, 2017. Companies may use either a full retrospective or modified retrospective approach to adopt this ASU and we are currently evaluating which transition approach to use and the full impact this ASU will have on our future consolidated financial statements.


	Note F - Critical Accounting Policies - Continued

	In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-15, Presentation of Financial Statements – Going Concern (Subtopic 205-40). The amendments in this ASU provide guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. An entity’s management should evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or are available to be issued, when applicable). ASU 2014-15 is effective for the Company beginning with the annual reporting for Fiscal 2016, and reports for interim and annual periods thereafter. Early adoption is permitted. The Company is evaluating the impact of adoption of this ASU, but does not expect the adoption to have a material impact on its consolidated financial statements.

Summary Of Significant Accounting Policies [Abstract]	'
Management Estimates And Uncertainties	'
	Management Estimates and Uncertainties - The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates made in preparing the consolidated financial statements include depreciation and amortization periods, the allowance for doubtful accounts, reserves for inventory and valuation of long-lived assets. Actual results could materially differ from these estimates.

The Company also has the option to bypass the qualitative assessment for goodwill in any period and proceed directly to performing the quantitative impairment test. The Company will be able to resume performing the qualitative assessment in any subsequent period. The Company performed its annual goodwill impairment test as of February 1, 2014 and determined that no impairment existed as of that date.
