In the case of a few large customers the Company has executed long-term Master Sales Agreements (“MSA”). These are umbrella agreements which typically define the terms and conditions under which a customer can order goods from CPS. These in themselves do not no no The Company contract is only enforceable once both parties have approved it, and is usually in the form of a written purchase order from a customer combined with acknowledgement from the Company. In cases without an MSA, the customer submits a blueprint for a product, the Company provides a quote and the customer responds with a purchase order. In these cases the Company’s acceptance of the purchase order constitutes an enforceable contract. Identifying the Performance Obligations in the Contract For each contract, the Company considers the promise to transfer products, each of which are distinct, to be the identified performance obligations.

Amounts collected from customers for sales value added and other taxes are excluded from the transaction prices. Product sales are recorded net of trade discounts and sales returns. If a contract includes a variable amount, such as a rebate, then the Company estimates the transaction price using either the expected value or the most likely amount of consideration to be received, depending upon the specific facts and circumstances.

Recognizing Revenue When (or as) the Performance Obligations are Satisfied The Company recognizes revenue at the point in time when it transfers control of the promised goods or services to the customer, which typically occurs once the product has shipped or has been delivered to the customer. Occasionally, for the purpose of ensuring a steady flow of product, the Company ships products on consignment. In these instances, delivery is deemed to have occurred when the customer pulls inventory out of the warehouse for use in their production, or upon a specified period of time as agreed upon by both parties.

Under this method, deferred tax assets and liabilities are recorded for the expected future tax consequences of temporary differences between the financial reporting and income tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in affect when the differences reverse. A valuation allowance is established to reduce net deferred tax assets to the amount expected to be realized. The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense.

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.

Direct costs associated with the estimated resolution of contingencies are accrued at the earliest date at which it is deemed probable that a liability has been incurred and the amount of such liability can be reasonably estimated. While it is impossible to ascertain the ultimate legal and financial liability with respect to contingent liabilities, including lawsuits, we believe that the aggregate amount of such liabilities, if any, in excess of amounts provided or covered by insurance, will not

Revenue [Policy Text Block]	( 2 Revenue is recognized in accordance with the five 606, Identifying the Contract with the Customer The Company identifies contracts with customers as agreements that create enforceable rights and obligations. In the case of a few large customers the Company has executed long-term Master Sales Agreements (“MSA”). These are umbrella agreements which typically define the terms and conditions under which a customer can order goods from CPS. These in themselves do not no no The Company contract is only enforceable once both parties have approved it, and is usually in the form of a written purchase order from a customer combined with acknowledgement from the Company. In cases without an MSA, the customer submits a blueprint for a product, the Company provides a quote and the customer responds with a purchase order. In these cases the Company’s acceptance of the purchase order constitutes an enforceable contract. Identifying the Performance Obligations in the Contract For each contract, the Company considers the promise to transfer products, each of which are distinct, to be the identified performance obligations. Shipping and handling activities for which the Company is responsible are not The Company provides an assurance-type warranty. This guarantees that the product functions as promised and meets specifications. Under its terms and conditions the Company offers a 30 not Determining the Transaction Price The Company determines the transaction price as the amount of consideration specified in the contract that it expects to receive in exchange for transferring promised goods to the customer. Amounts collected from customers for sales value added and other taxes are excluded from the transaction prices. Product sales are recorded net of trade discounts and sales returns. If a contract includes a variable amount, such as a rebate, then the Company estimates the transaction price using either the expected value or the most likely amount of consideration to be received, depending upon the specific facts and circumstances. The Company includes estimated variable consideration in the transaction price only to the extent it is probable that a significant reversal of revenue will not December 25, 2021 When credit is granted to customers, payment is typically due 30 90 not Allocating the Transaction Price to the Performance Obligations In virtually all cases the transaction price is tied to a specific product in the contract obviating the need for any allocation. Recognizing Revenue When (or as) the Performance Obligations are Satisfied The Company recognizes revenue at the point in time when it transfers control of the promised goods or services to the customer, which typically occurs once the product has shipped or has been delivered to the customer. Occasionally, for the purpose of ensuring a steady flow of product, the Company ships products on consignment. In these instances, delivery is deemed to have occurred when the customer pulls inventory out of the warehouse for use in their production, or upon a specified period of time as agreed upon by both parties. As of December 25, 2021 The Company generally expenses sales commissions when incurred because the amortization period would have been one The Company does not one
Income Tax, Policy [Policy Text Block]	( 2 The Company uses the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recorded for the expected future tax consequences of temporary differences between the financial reporting and income tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in affect when the differences reverse. A valuation allowance is established to reduce net deferred tax assets to the amount expected to be realized. The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense. As of December 25, 2021 December 26, 2020, not December 25, 2021 December 26, 2020
Earnings Per Share, Policy [Policy Text Block]	( 2 Basic net income (loss) per common share is calculated by dividing net income (loss) 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.
