Fair Value Of Financial Instruments

Fair Value Of Financial Instruments	Oct. 04, 2015
Fair Value Of Financial Instruments [Abstract]
Fair Value Of Financial Instruments	NOTE E - FAIR VALUE OF FINANCIAL INSTRUMENTS The Company utilizes the methods of fair value as described in Financial Accounting Standard Board (“FASB”) Accounting Standard Codification (“ASC”) 820, Fair Value Measurements and Disclosures, to value its financial assets and liabilities. ASC 820 utilizes a three-tier fair value hierarchy which prioritizes the inputs used in measuring 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 in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The carrying amount for cash and cash equivalents, accounts receivable, note receivable, accounts payable, and accrued liabilities approximates fair value due to the immediate or short-term maturity of these financial instruments.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Cash, Cash Equivalents And Marketable Securities [Abstract]

Cash, Cash Equivalents And Marketable Securities

NOTE F - CASH, CASH EQUIVALENTS AND MARKETABLE SECURITIES

The Company considers all highly liquid marketable securities with an original maturity of three months or less to be cash equivalents. Cash equivalents include money market funds. The Company deposits its cash in high quality financial institutions. The balances, at times, may exceed federally insured limits. Money market funds are reported at fair value determined using quoted prices in active markets for identical securities (Level 1, as defined by FASB ASC 820).

The Company has classified all marketable securities as available-for-sale which requires the securities to be reported at estimated fair value, with unrealized gains and losses, net of tax, reported as a separate component of stockholders' equity. Highly liquid, tax-exempt variable rate demand notes with put options exercisable in three months or less are classified as marketable securities.

At October 4, 2015 and December 31, 2014, cost for marketable securities was determined using the specific identification method. A summary of the amortized costs and fair values of the Company’s marketable securities at the end of the periods presented is shown in the following table. All of the Company’s marketable securities are classified as Level 2, as defined by FASB ASC 820, with fair values determined using significant other observable inputs, which include quoted prices in markets that are not active, quoted prices of similar securities, recently executed transactions, broker quotations, and other inputs that are observable. There were no transfers into or out of Level 2 during the nine months ended October 4, 2015.

All of the instruments in the beyond five year ranges are variable rate demand notes which can be tendered for cash at par plus interest within seven days. Despite the stated contractual maturity date, to the extent a tender is not honored, the notes become immediately due and payable.

Business Acquisition [Abstract]

Business Acquisition

NOTE I – BUSINESS ACQUISITION

On January 24, 2014, AMTEC Corporation, a wholly-owned subsidiary of the Company, purchased substantially all of the assets of Chemring Energetic Devices, Inc.’s business located in Clear Lake, South Dakota, and all of the real property owned by Technical Ordnance Realty, LLC. The Clear Lake facility is a manufacturer of detonators, booster pellets, release cartridges, lead azide, and other military energetic devices and materials. Its major customers include U.S. and foreign government agencies, AMTEC Corporation, and other defense contractors. The acquisition of the Clear Lake facility complements the Defense segment’s existing line of products. The total consideration transferred was $10,534,000, consisting of $10,000,000 of cash paid at closing, and an additional cash payment of $534,000, which was made during the second quarter of 2014.

The acquisition was accounted for under the acquisition method of accounting with the Company treated as the acquiring entity. Accordingly, the consideration paid by the Company to complete the acquisition has been recorded to the assets acquired and liabilities assumed based upon their estimated fair values as of the date of acquisition. The carrying values for current assets and liabilities were deemed to approximate their fair values due to the short-term nature of these assets and liabilities. The following table shows the amounts recorded as of the acquisition date.

Other current assets		28
Property, plant and equipment		4,800

Net assets acquired	$	10,534

The amount shown above for receivables represents the gross accounts receivable from the sales of goods, net of an allowance for doubtful accounts of $20,000.

The Company’s statement of comprehensive income includes revenue and earnings from the acquired facility of $5,294,000 and $171,000, respectively, for the third quarter of 2014, and $11,301,000 and $876,000, respectively, for the period starting from the date of acquisition through the end of the third quarter of 2014. The following unaudited pro forma condensed consolidated results of operations has been prepared as if the acquisition had occurred as of the first day of the fiscal year prior to the fiscal year in which the acquisition was completed.

Recently Issued Accounting Pronouncements [Abstract]
Recently Issued Accounting Pronouncements	NOTE J – RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In September 2015, the FASB issued Accounting Standards Update (“ASU”) 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. ASU 2015-16 requires the acquirer in a business combination to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The new guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2015. Early adoption is permitted for financial statements that have not been previously issued. The Company does not expect the adoption of ASU 2015-16 to have a material impact on its consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. ASU 2015-11 requires inventory to be measured at the lower of cost and net realizable value. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. ASU 2015-11 does not apply to inventory that is measured using last-in, first-out (LIFO) or the retail inventory method, but applies to all other inventory, which includes inventory that is measured using first-in, first-out (FIFO) or average cost. ASU 2015-11 is effective for public business entities for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect the adoption of ASU 2015-11 to have a material impact on its consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) which amended the existing accounting standards for revenue recognition. ASU 2014-09 establishes principles for recognizing revenue upon the transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. It is effective for annual reporting periods beginning after December 15, 2017. Early adoption is permitted as of annual reporting periods beginning after December 15, 2016. The amendment may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. The Company is currently in the process of evaluating the impact of adoption of the ASU on its consolidated financial statements, but does not expect the impact to be material.
