(“the Company”), the accompanying unaudited condensed consolidated interim financial statements reflect all adjustments (which include only normal recurring adjustments) necessary to present fairly, in all material respects, the consolidated financial position of the Company as of July 31, 2015 and the results of its operations and cash flows for the three months ended July 31, 2015 and 2014. The April 30, 2015 condensed consolidated balance sheet was derived from audited financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted. It is suggested that these condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended April 30, 2015 filed on July 29, 2015.

Earnings Per Share [Text Block]

NOTE B – EARNINGS PER SHARE

Reconciliation of the weighted average shares outstanding for basic and diluted Earnings Per Share are as follows:

	Three months ended July 31,
	2015		2014
Basic EPS Shares outstanding (weighted average)		8,706,185		8,578,733
Effect of Dilutive Securities		277,852		278,116
Diluted EPS Shares outstanding		8,984,037		8,856,849

The computation of diluted earnings per share excludes those options and stock appreciation rights (“SARS”) with an exercise price in excess of the average market price of the Company’s common shares during the periods presented. The inclusion of such options and SARS in the computation of earnings per share would have been antidilutive. The number of excluded options and SARS for the three months ended July 31, 2015 and 2014 were 330,500 and 300,875, respectively.

Segment Reporting [Abstract]

Segment Reporting Disclosure [Text Block]

NOTE F – SEGMENT INFORMATION

The Company operates under three reportable segments based on the geographic locations of its subsidiaries:

(1)

FEI-NY – operates out of New York and its operations consist principally of precision time and frequency control products used in three principal markets- communication satellites (both commercial and U.S. Government-funded); terrestrial cellular telephone or other ground-based telecommunication stations and other components and systems for the U.S. military.

(2)	Gillam-FEI - operates out of Belgium and France and primarily sells wireline synchronization and network management systems in non-U.S. markets. All sales from Gillam-FEI to the United States are to other segments of the Company.

(3)

FEI-Zyfer – operates out of California and its products incorporate Global Positioning System (GPS) technologies into systems and subsystems for secure communications, both government and commercial, and other locator applications. This segment also provides sales and support for the Company’s wireline telecommunications family of products, including US5G, which are sold in the United States market.

The FEI-NY segment also includes the operations of the Company’s wholly-owned subsidiaries, FEI-Elcom Tech (“FEI-Elcom”) and FEI-Asia. FEI-Asia functions primarily as a manufacturing facility for the Company’s commercial product subsidiaries with historically minimal sales to outside customers. Beginning in late fiscal year 2014, FEI-Asia began shipping higher volumes of product to third parties as a contract manufacturer. FEI-Elcom, in addition to its own product line, provides design and technical support for the FEI-NY segment’s satellite business.

The Company’s chief executive officer measures segment performance based on total revenues and profits generated by each geographic location rather than on the specific types of customers or end- users. Consequently, the Company determined that the segments indicated above most appropriately reflect the way the Company’s management views the business.

The tables below presents information about reported segments with reconciliation of segment amounts to consolidated amounts as reported in the statement of operations or the balance sheet for each of the periods (in thousands):

	Three months ended July 31,

NOTE G - INVESTMENT IN MORION, INC.	Jul. 31, 2015
Investment Holdings [Abstract]
Investment Holdings [Text Block]	NOTE G – INVESTMENT IN MORION, INC. The Company has an investment in Morion, Inc., (“Morion”) a privately-held Russian company, which manufactures high precision quartz resonators and crystal oscillators. The Company’s investment consists of 4.6% of Morion’s outstanding shares, accordingly, the Company accounts for its investment in Morion on the cost basis. This investment is included in other assets in the accompanying balance sheets. During the three months ended July 31, 2015 and 2014, the Company acquired product from Morion in the aggregate amount of approximately $32,000 and $65,000, respectively, and the Company sold product and services to Morion in the aggregate amount of approximately $423,000 and $183,000, respectively. At July 31, 2015 and April 30, 2015, accounts receivable included $429,000 and $145,000, respectively, due from Morion and $0 and $23,000, respectively, was payable to Morion. On October 22, 2012, the Company entered into an agreement to license its rubidium oscillator production technology to Morion. The agreement required the Company to sell certain fully-depreciated production equipment previously owned by the Company and to provide training to Morion employees to enable Morion to produce a minimum of 5,000 rubidium oscillators per year. Morion will pay the Company approximately $2.7 million for the license and the equipment plus 5% royalties on third party sales for a 5-year period following an initial production run. During the same 5-year period, the Company commits to purchase from Morion a minimum of approximately $400,000 worth of rubidium oscillators per year although Morion is not obligated to sell that amount to the Company. In November 2012, Morion paid the Company a $925,000 deposit under the agreement which amount had been recorded on the Company’s balance sheet as deferred revenue. In October 2013, after amending the original document to clarify certain billing events, the Company invoiced Morion for the equipment, certain component parts for the production of rubidium oscillators, training of certain Morion employees and transfer of the production technology and license to Morion. The $925,000 deposit previously recorded as deferred revenue was recognized as income during the second quarter of fiscal year 2015. For the three months ended July 31, 2015, sales to Morion included $375,000 for product and training services under this agreement. During the first quarter of fiscal year 2015, there were no sales to Morion under the agreement. Per the amended agreement, the balance of $1 million for the transfer of the license will be due once the United States Department of State (“State Department”) approves the removal of certain provisions of the original agreement. The State Department has approved the technology transfer called for under the agreement.

The Company regularly reviews its investment portfolio to identify and evaluate investments that have indications of possible impairment. The Company does not believe that its investments in marketable securities with unrealized losses at July 31, 2015 are other-than-temporary due to market volatility of the security’s fair value, analysts’ expectations and the Company’s ability to hold the securities for a period of time sufficient to allow for any anticipated recoveries in market value.

During the three months ended July 31, 2015 and 2014, the Company sold or redeemed available-for-sale securities in the amounts of $713,000 and $2.2 million, respectively, realizing gains of approximately $137,000 and $280,000, respectively.

Maturities of fixed income securities classified as available-for-sale at July 31, 2015 are as follows, at cost (in thousands):

Current	$	101
Due after one year through five years		1,622
Due after five years through ten years		1,502

The fair value accounting framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy are described below:

Level 1

Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access.

Level 2

Inputs to the valuation methodology include:

- Quoted prices for similar assets or liabilities in active markets;

- Quoted prices for identical or similar assets or liabilities in inactive markets

- Inputs other than quoted prices that are observable for the asset or liability;

- Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3

Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs. All of the Company’s investments in marketable securities are valued on a Level 1 basis.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	NOTE I – RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 eliminates most of the existing industry-specific revenue recognition guidance and significantly expands related disclosures. The required disclosures will include both quantitative and qualitative information about the amount, timing and uncertainty of revenue from contracts with customers and the significant judgments used. Entities can retrospectively apply ASU 2014-09 or use an alternative transition method. In August 2015, the FASB issued ASU 2015-14 which provides a one-year deferral of the effective date of ASU 2014-09, while allowing companies to early adopt based on the original effective date of ASU 2014-09. ASU 2014-09 is now effective for public companies for annual reporting periods beginning on or after December 15, 2017 and for the Company, must be adopted for its fiscal year 2019 beginning on May 1, 2018. The Company is in the process of determining the effect that ASU 2014-09 may have on its financial statements.

NOTE J - CREDIT FACILITY	Jul. 31, 2015
Debt Disclosure [Abstract]
Debt Disclosure [Text Block]	NOTE J – CREDIT FACILITY The Company has a credit facility (the “Facility”) with JPMorgan Chase Bank, N.A. (“JPMorgan”) pursuant to a credit agreement (the “Credit Agreement”) between the Company and JPMorgan. Under the Facility the Company may make borrowings from either Tranche A or Tranche B or a combination of both, not to exceed $25.0 million. Pursuant to the Credit Agreement, the amount of Tranche A borrowings may not exceed the value of the Pledged Investments (as defined in the Credit Agreement). The amount of Tranche B borrowings may not exceed the lesser of (i) $15.0 million and (ii) the Borrowing Base (as defined in the Credit Agreement). Current outstanding borrowings of $6.0 million under the Facility are all under Tranche A. The Facility is fully guaranteed by certain of the Company’s subsidiaries and is secured by, among other things, a pledge of substantially all personal property of the Company and certain of the Company’s subsidiaries. Borrowings under the Facility are evidenced by a line of credit note (the “Note”) and bear interest, payable monthly, at a rate equal to the LIBOR Rate, as determined from time to time by JPMorgan pursuant to the terms of the Note, plus a margin of 0.75% for Tranche A borrowings and 1.75% for Tranche B borrowings. The principal balance on the Note, along with any accrued and unpaid interest, is due and payable no later than June 5, 2018, which is the maturity date of the Facility. In addition, the Company is required to pay JPMorgan fees equal to 0.1% per annum on any unused portion of the Facility. The Credit Agreement contains a number of affirmative and negative covenants, including limitations on the incurrence of additional debt, liens on property, acquisitions, loans and guarantees, mergers, consolidations, liquidations and dissolutions, asset sales, and distributions and other payments in respect of the Company’s capital stock. The Credit Agreement also contains certain events of default customary for credit facilities of this type, including nonpayment of principal or interest when due, material incorrectness of representations and warranties when made, breach of covenants, bankruptcy and insolvency, unstayed material judgment beyond specified periods, and acceleration or payment default of other material indebtedness. The Credit Agreement requires the Company to maintain, as of the end of each fiscal quarter, a funded debt to EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) ratio and an interest charge coverage ratio. The calculation of both ratios is defined in the Credit Agreement. For the period ended July 31, 2015, the Company met the required covenants for its borrowings under Tranche A.
