Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(2) Summary of Significant Accounting Policies (2)(a) Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less at the date of purchase to be cash equivalents. (2)(b) Accounts Receivable The Company reports its accounts receivable at the invoiced amount less an allowance for doubtful accounts. The Company’s management provides appropriate provisions for uncollectible accounts based upon factors surrounding the credit risk and activity of specific customers, historical trends, economic conditions and other information. Adjustments to the allowance are charged to operations in the period in which information becomes available that may affect the allowance. Sales returns are offset against the related amounts invoiced in accounts receivable. (2)(c) Inventories Inventories are stated at the lower of cost or market, as determined under the first-in, first-out method (FIFO), or market. A reserve for obsolete inventories, if any, is based on factors regarding the sales and usage of such inventories, including inventories manufactured for specific customers. The Company’s general obsolescence policy is to write off obsolete inventory when there has been no activity on a particular part for a twelve month period and there are no pending customer orders. (2)(d) Property and Equipment Property and equipment are stated at cost. Depreciation of equipment is calculated on a straight-line basis over the estimated useful life, generally five years for production equipment and three to five years for furniture and office equipment. Amortization of equipment under capital leases is calculated on a straight-line basis over the shorter of the life of the lease or the estimated useful life of the equipment. Maintenance and repairs are charged to expense as incurred. Upon retirement or sale, the cost and related accumulated depreciation or amortization are removed from their respective accounts. Any gains or losses on the disposition of property and equipment are included in the results of operations in the period in which they occur. (2)(e) Impairment of Long-Lived Assets The Company reviews long-lived assets for impairment whenever circumstances and situations change such that there is an indication that the carrying amounts may not be recovered. Recoverability is assessed based on estimated undiscounted future cash flows. As of December 28, 2013 and December 29, 2012, the Company believes that there has been no impairment of its long-lived assets. (2)(f) Revenue Recognition The Company recognizes revenue in accordance with the provision of the Securities and Exchange Commission Staff Accounting Bulletin ("SAB") No. 104 which establishes guidance in applying generally accepted accounting principles to revenue recognition in financial statements. SAB No. 104 requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services rendered; (3) the price to the buyer is fixed or determinable; and (4) collectability is reasonably assured. Shipping terms are customarily EXW (Ex-works), shipping point which terms are consistent with “FOB Shipping Point”. Revenues for products sold in the normal course of business are recognized upon shipment when delivery terms are EXW shipping point and all other revenue recognition criteria have been met. The Company has entered into consigned inventory agreements with a few customers. For products shipped under consigned inventory agreements, the Company recognizes revenue when either the customer notifies CPS that they have picked the product from the consigned inventory or, in some cases, when sixty days have elapsed from the date the shipment arrives at the customer’s location. In 2008, CPS entered into a cooperative agreement with the US Army Research Laboratory to perform research and development concerning hybrid metal matrix composite encapsulated ceramic armor technology. The Cooperative Agreement was a four-year agreement which was subsequently extended through July 14, 2014. This agreement was 95% funded by the US Department of Defense and 5% funded by CPS. Revenues on this Cooperative Agreement are recognized proportionally as costs are incurred. The Company is reimbursed for reasonable and allocable costs up to the reimbursement limits set by the Cooperative Agreement. All payments to the Company for work performed on this Cooperative Agreement are subject to audit and adjustment by the Defense Contract Audit Agency. Adjustments, if any, are recognized in the period made. The Cooperative Agreement extends for four years and provides for funding of up to $8.34 million, over the four years, but actual funding is provided incrementally on a year-to-year basis, depending on, among other factors, if yearly objectives are met and if Congress authorizes the funds ($6.6 million has been authorized through December 28, 2013). If the total $8.34 million in funding is provided by the Government, the Company’s cost share will amount to $439 thousand over the term of the Agreement. Amendment/Modification #P00009 extended the term of performance of the original Agreement, Cooperative Agreement W911NF-08-2-0017, from July 14, 2013 to July 14, 2014. As of December 28, 2013, the Company had invoiced $6.6 million since inception of the Agreement which represents the full amount approved to date of $6.6 million. (2)(g) Research and Development Costs In 2013, costs incurred related to funding under the Cooperative Agreement totaled $311 thousand of which 100% was reimbursed by the U.S. Army and was recorded as revenue. This revenue of $311 thousand resulted in a gross margin of $52 thousand. In 2012, costs incurred related to funding under the Cooperative Agreement were $605 thousand of which $597 thousand is reimbursed by the U.S. Army and $8 thousand is the Company’s cost share. The revenue recognized by the Company of $597 thousand less the Company’s research and development cost of $502 thousand resulted in a gross margin of $95 thousand. In 2011, costs incurred related to total funding under the Cooperative Agreement were $2.259 million of which $2.164 million was reimbursed by the U.S. Army and $95 thousand was the Company’s cost share. The revenue recognized by the Company of $2.164 million less the Company’s research and development costs of $1.973 million resulted in a gross margin of $191 thousand. (2)(h) Income Taxes Deferred tax assets and liabilities are based on the net tax effects of tax credits, operating loss carryforwards and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company considers many factors in assessing whether or not a valuation allowance for its Deferred Tax asset is warranted. On the positive side, the Company considered such factors as its: history of taxable earnings (seven consecutive years from 2003-10), global customer base consisting of large companies with significant resources, current products and their expected life, technological advantages, potential for price increases, trend of improved manufacturing efficiencies and the magnitude of the Deferred Tax Asset compared with the Company’s expectation of future earnings over the remaining life of the asset. On the negative side, the Company considered such factors as: the current global recession, the Company’s ability to absorb additional periods of operating losses and negative cash flow and the potential for the technological breakthroughs and substitution of the Company’s products by lower cost solutions. The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense. As of December 28, 2013 and December 29, 2012, the Company has no accruals for interest or penalties related to income tax matters. The Company does not have any uncertain tax positions at December 28, 2013 or December 29, 2012 which required accrual or disclosure. Income tax effects related to share-based compensation that are in excess, or less than, of grant-date fair value, less any proceeds received on exercise of stock prices, are recognized as either an increase or decrease to additional paid-in capital upon exercise. These tax effects are either offset against currently payable taxes or the tax benefit of net operating loss utilization. (2)(i) Net Income (Loss) Per Common Share Basic net income (loss) per common share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per common share is calculated by dividing net income (loss) by the sum of the weighted average number of common shares plus additional common shares that would have been outstanding if potential dilutive common shares had been issued for granted stock option and stock purchase rights. Common stock equivalents are excluded from the diluted calculations when a net loss is incurred as they would be anti-dilutive. (2)(j) Comprehensive Income The Company has no items of comprehensive income, and therefore net income is equal to comprehensive income. (2)(k) Recent Accounting Pronouncements In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-11 Income Taxes (Topic 740) - Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists that provides guidance on whether an uncertain tax position should be presented as a reduction to a deferred tax asset or as a reduction to a deferred tax asset or as a separate liability. This guidance seeks to address diversity in practice. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The Company does not expect the adoption of this ASU amendment to have any affect on the financial condition, results of operations or cash flows. (2)(l) Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 amounts of revenues and expenses recorded during the reporting period. Such estimates are adjusted by management periodically as a result of existing or anticipated economic changes which effect, or may effect, the Company’s financial statements. Actual results could differ from these estimates. (2)(m) Fiscal Year-End The Company’s fiscal year end is the last Saturday in December which could result in a 52 or 53 week year. Fiscal year 2013 and 2012 consisted of 52 weeks, 2011 consisted of 53 weeks. (2)(n) Share-Based Payments The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. That cost is recognized over the period during which an employee is required to provide services in exchange for the award, the requisite service period (usually the vesting period). The Company provides an estimate of forfeitures at initial grant date, and this estimated forfeiture rate is adjusted periodically based on actual forfeiture experience. The Company uses the Black-Scholes option pricing model to determine the fair value of stock options granted. (2)(o) Segment Reporting The Company views its operations and manages its business as one segment. The Company produces and sells advanced material solutions, primarily metal matrix composites, to assemblers of high density electronics and other specialty components and subassemblies. The Company also assembles housings and packages for hybrid circuits, selling to the same customers mentioned above. These customers represent a single market or segment with similar stringent and well-defined requirements. The Company’s customers, in turn, sell the components and subassemblies which incorporate the products into many different end markets, however, these end markets are two to three levels removed from the Company. The Company makes operating decisions and assesses financial performance only for the Company as a whole and does not make operating decisions or assess financial performance by the end markets which ultimately use the products. The Cooperative Agreement the Company entered into with the Army Research Laboratory in 2008 uses the same equipment and personnel as does the Company’s electronics business described above, and at this stage does not represent a separate business segment. (2)(p) Reclassifications Certain amounts 2011 and 2012 have been reclassified to conform with the 2013 financial statement presentation.
