Accounting Policies [Abstract] |
Critical Accounting Policies | The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Although the Company makes every effort to ensure the accuracy of the estimates and assumptions used in the preparation of its condensed consolidated financial statements or in the application of accounting policies, if business conditions were different, or if the Company were to use different estimates and assumptions, it is possible that materially different amounts could be reported in the Company's condensed consolidated financial statements. Notes 1 and 3 to the consolidated financial statements in the Company's Annual Report on Form 10-K for the fiscal year ended December 29, 2018 describe the significant accounting estimates and policies used in preparation of the consolidated financial statements. There have been no material changes in the Company’s significant accounting policies during the six months ended June 29, 2019, except for the adoption of Accounting Standards Codification (ASC), Leases (Topic 842) (ASC 842). See Recently Adopted Accounting Pronouncements within this note and Note 8 for further details.
Use of Estimates | Although the Company makes every effort to ensure the accuracy of the estimates and assumptions used in the preparation of its condensed consolidated financial statements or in the application of accounting policies, if business conditions were different, or if the Company were to use different estimates and assumptions, it is possible that materially different amounts could be reported in the Company's condensed consolidated financial statements.
Restricted Cash | The Company's restricted cash serves as collateral for bank guarantees primarily associated with providing assurance to customers that the Company will fulfill certain customer obligations entered into in the normal course of business. The majority of the bank guarantees will expire over the next twelve months.
Banker's Acceptance Drafts Included in Accounts Receivable | The Company's Chinese subsidiaries may receive banker's acceptance drafts from customers as payment for their trade accounts receivable. The drafts are noninterest-bearing obligations of the issuing bank and mature within six months of the origination date. The Company's subsidiaries may sell the drafts at a discount to a third-party financial institution or transfer the drafts to vendors in settlement of current accounts payable prior to the scheduled maturity date. These drafts, which totaled $7,706,000 at June 29, 2019 and $7,976,000 at December 29, 2018, are included in accounts receivable in the accompanying condensed consolidated balance sheet until the subsidiary sells the drafts to a bank and receives a discounted amount, transfers the banker's acceptance drafts in settlement of current accounts payable prior to maturity, or obtains cash payment on the scheduled maturity date.
Revenue Recognition | Contract assets represent unbilled revenues associated with revenue recognized on contracts accounted for on an over time basis, which will be billed in future periods based on the contract terms. Contract liabilities consist of customer deposits, advanced billings, and deferred revenue. Deferred revenue is included in other current liabilities in the accompanying condensed consolidated balance sheet. Contract liabilities will be recognized as revenue in future periods once the revenue recognition criteria are met. The majority of the contract liabilities relate to advanced payments on contracts accounted for at a point in time. These advance payments will be recognized as revenue when the Company's performance obligations have been satisfied, which typically occurs when the product has shipped and control of the asset has transferred to the customer. The Company recognized revenue of $4,427,000 in the second quarter of 2019, $2,788,000 in the second quarter of 2018, $23,522,000 in the first six months of 2019 and $30,113,000 in the first six months of 2018 that was included in the contract liabilities balance at the beginning of 2019 and 2018 for the respective periods. Customers in China will often settle their accounts receivable with a banker's acceptance draft, in which case cash settlement will be delayed until the banker's acceptance draft matures or is settled prior to maturity. For customers outside of China, final payment for the majority of the Company's products is received in the quarter following the product shipment. Certain of the Company's contracts include a longer period before final payment is due, which is typically within one year of final shipment or transfer of control to the customer. The Company recognizes revenue under ASC 606, Revenue from Contracts with Customers. Most of the Company’s revenue is recognized at a point in time for each performance obligation under the contract when the customer obtains control of the goods or service. The majority of the Company’s parts and consumables products and capital products with minimal customization are accounted for at a point in time. The Company has made a policy election not to treat the obligation to ship as a separate performance obligation under the contract and, as a result, the associated shipping costs are accrued when revenue is recognized. The remaining portion of the Company’s revenue is recognized on an over time basis based on an input method that compares the costs incurred to date to the total expected costs required to satisfy the performance obligation. Contracts are accounted for on an over time basis when they include products which have no alternative use and an enforceable right to payment over time. Contracts recognized on an over time basis are typically for large capital projects which are highly customized for the customer and, as a result, would include a significant cost to rework in the event of cancellation. The transaction price is typically based on the amount billed to the customer and includes estimated variable consideration where applicable. Such variable consideration relates to certain performance guarantees and rights to return the product. The Company estimates variable consideration as the most likely amount to which it expects to be entitled based on the terms of the contracts with customers and historical experience, where relevant. For contracts with multiple performance obligations, the transaction price is allocated to each performance obligation based on the relative stand-alone selling price.
Recent Accounting Pronouncements | Recently Adopted Accounting Pronouncements Leases (Topic 842). In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-02, which requires a lessee to recognize a right-of-use (ROU) asset and a corresponding lease liability for operating leases, initially measured at the present value of the future lease payments, on its balance sheet. This ASU also requires a lessee to recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term, generally on a straight-line basis. The Company adopted this ASU as of the beginning of fiscal 2019 using the cumulative-effect adjustment method. As a result, prior period amounts were not restated and continue to be accounted for under Topic 840, Leases, which did not require the recognition of operating leases on the balance sheet and is not comparative. As permitted under ASC 842, the Company elected the package of practical expedients for expired or existing contracts, which does not require the reassessment of prior conclusions about lease identification, lease classification and initial direct costs. The Company also elected practical expedients relating to its ongoing accounting, including a short-term lease recognition exemption allowing lessees not to recognize ROU assets and liabilities with a term of 12 months or less and an election not to separate lease and non-lease components for all leases except vehicle leases. The adoption of this standard as of the beginning of fiscal 2019 resulted in increases of 2.3% to total assets and 4.8% to total liabilities and an immaterial decrease to retained earnings. In addition, the adoption of this ASU did not have a material impact on the Company’s condensed consolidated statements of income or cash flows. See Note 8, Leases, for required lease accounting disclosures. Derivatives and Hedging (Topic 815), Targeted Improvements in Accounting for Hedging Activity. In August 2017, the FASB issued ASU No. 2017-12, which revises hedge accounting to better portray the economic results of an entity’s risk management activities, simplifies hedge accounting guidance, and improves disclosures of hedge accounting arrangements. The Company adopted this ASU on a prospective basis at the beginning of fiscal 2019. The adoption of this ASU did not have an impact on the Company's condensed consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. In June 2016, the FASB issued ASU No. 2016-13, which significantly changes the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining lives. This new guidance is effective for the Company in fiscal 2020 with early adoption permitted beginning in fiscal 2019. The Company is currently evaluating the effects that the adoption of this ASU will have on its condensed consolidated financial statements. Compensation-Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20), Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. In August 2018, the FASB issued ASU 2018-14, which removes, adds and clarifies several disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. This new guidance is effective on a retrospective basis for the Company in fiscal 2021. Early adoption is permitted. The Company does not believe that the adoption of this ASU will have a material effect on its condensed consolidated financial statements.
Derivatives | The Company uses derivative instruments primarily to reduce its exposure to changes in currency exchange rates and interest rates. At the inception of a derivative contract, the Company determines whether the transaction is deemed a hedge. If deemed a hedge, the Company documents the relationship between the derivative instrument and the risk being hedged. In this documentation, the Company identifies the hedged item and evaluates whether the derivative instrument is expected to reduce the risks associated with such item in order to qualify for hedge accounting. The Company believes that any credit risk associated with its derivative instruments is remote based on the creditworthiness of the financial institutions issuing those agreements. The Company does not hold or engage in transactions involving derivative instruments for purposes other than risk management.
Fair Value Measurement | The carrying value of the Company's revolving credit facility approximates the fair value as the obligation bears variable rates of interest, which adjust frequently, based on prevailing market rates. The fair values of the commercial real estate loan and senior promissory notes are primarily calculated based on quoted market rates plus an applicable margin available to the Company at the respective period ends, which represent Level 2 measurements. The Company uses the market approach technique to value its financial assets and liabilities, and there were no changes in valuation techniques during the first six months of 2019. The Company's banker's acceptance drafts are carried at face value which approximates their fair value due to the short-term nature of the negotiable instrument. The fair values of the Company's forward currency-exchange contracts are based on quoted forward foreign exchange rates at the reporting date. The fair values of the Company's interest rate swap agreements are based on LIBOR yield curves at the reporting date. The forward currency-exchange contracts and interest rate swap agreements are hedges of either recorded assets or liabilities or anticipated transactions and represent the estimated amount the Company would receive or pay upon liquidation of the contracts. Changes in values of the underlying hedged assets and liabilities or anticipated transactions are not reflected in the table above.
