Accounting Policies [Abstract]
Significant Accounting Policies Update	SIGNIFICANT ACCOUNTING POLICIES UPDATE The Company's significant accounting policies are detailed in Note 1, Summary of Significant Accounting Policies of its Annual Report on Form 10-K for the year-ended December 31, 2018. Significant changes to our accounting policies as a result of adopting new accounting standards are discussed below: Leasing Under Accounting Standards Codification ("ASC") 842, the Company determines if a contract contains a lease at the inception date of the contract. To determine if the contract contains a lease, the Company evaluates if there is an identified asset in the contract and if the Company has control over the use of the identified asset. There is an identified asset in the contract if the asset is explicitly or implicitly specified in the contract, the asset is physically distinct or the Company has the right to receive substantially all of the asset's capacity, and if the supplier does not have substantive substitution rights. The Company has control over the use of the identified asset if the Company obtains substantially all economic benefits from the use of the asset and can direct the use of the asset. The Company applied the practical expedient for any contracts that existed prior to January 1, 2019; therefore, the contracts were not reassessed to determine if they contain leases. The Company must classify each lease as a finance lease or operating lease. A lease is classified as a finance lease if the Company will own the asset by the end of the lease term, the Company is reasonably certain to exercise the purchase option, the lease term covers a major part of the asset's economic life, the sum of the present value of the lease payments and the present value of the residual value guarantee not included in the lease payments equal or exceed substantially all of the fair value of the underlying asset at lease commencement or if the lessor has no alternative use for the asset. If any of these criteria are not met, the lease is classified as an operating lease. The Company applied the practical expedient for any leases that existed prior to January 1, 2019; therefore, the lease classifications of existing leases were not reassessed (all existing leases classified as operating leases under ASC 840 were classified as operating leases under ASC 842 on January 1, 2019 and all existing leases classified as capital leases under ASC 840 were classified as finance leases under ASC 842 on January 1, 2019). The Company's operating leases consist of rent commitments under various leases for office space, warehouses, land and buildings at varying dates from January 2019 to June 2028. The terms of most of these leases are in the range of 3 to 10 years. Some of the Company's leases have fixed amount rent escalations, rent holidays or contingent rent that are recognized on a straight-line basis over the entire lease term. Material leasehold improvements and other landlord incentives are amortized over the shorter of their economic lives or the lease term, including renewal periods, if reasonably assured. Certain annual rentals are subject to renegotiation, with certain leases renewable for varying periods and certain leases including options to terminate the leases. While some of the Company's leases include options allowing early termination of the lease, the Company historically has not terminated its lease agreements early unless there is an economic, financial or business reason to do so. Substantially all real estate taxes, insurance and maintenance expenses associated with leased facilities are obligations of the Company. It is expected that in the normal course of business leases that expire will be renewed or replaced by leases on other similar property. The terms for most machinery and equipment leases range from 3 to 5 years. 3. SIGNIFICANT ACCOUNTING POLICIES UPDATE (CONTINUED) Leasing - continued The majority of the Company's finance leases consist of assets purchased under the Company's master leasing agreement with PNC Equipment Finance ("PNC"), and are included in machinery, office furniture and equipment and construction in process. At March 29, 2019, the Company's master leasing agreement with PNC had a maximum capacity of $20.0 million. The terms of these leases are 5 years. Amortization of these assets is included in depreciation and amortization expense. At the commencement date, the right-of-use asset and lease liability are recorded to the Company's Condensed Consolidated Balance Sheets when the Company obtains control of the use of the asset. Right-of-use assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make payments upon entering into a lease agreement. The initial measurement of the lease liability is equal to the present value of the unpaid lease payments. Subsequent to the initial measurement, the lease liability continues to be measured at the present value of unpaid lease payments throughout the lease term. The lease liability is remeasured if the lease is modified and the modification is not accounted for as a separate contract, there is a change in the assessment of the lease term, the assessment of a purchase option exercise or the amount probable of being owed under a residual value guarantee, or a contingency is resolved resulting in some or all of the variable lease payments becoming fixed payments. The initial measurement of the right-of-use asset is equal to the total of the initial measurement of the lease liability, incremental costs to obtain the lease and prepaid lease payments, less any lease incentives received. Subsequent to the initial measurement, the right-of-use asset for a finance lease is equivalent to the initial measurement less accumulated amortization and any accumulated impairment losses. Generally, amortization of finance leases is recorded to cost of sales on a straight-line basis over the lease term. Subsequent to initial measurement, the right-of-use asset for an operating lease is equivalent to initial measurement less accumulated amortization (the difference between the straight-line lease cost for the period and the accretion of the lease liability using the effective interest method). The Company has elected not to apply the recognition requirements of ASC 842 to short-term leases (leases that, at the commencement date, have a lease term of twelve months or less and do not include an option to purchase the underlying asset that the lessee is reasonably certain to exercise) as permissible under the standard. For short-term leases, the Company recognizes lease payments on a straight-line basis and variable payments in the period in which the obligation for those payments is incurred. Leasing contracts can be separated into lease components, non-lease components and items that are not components of the contract (items that do not transfer a good or service to the Company). Two or more contracts may be combined if at least one of which is or contains a lease entered into or near the same time with the same counterparty and consider the contracts as a single transaction if the contracts are negotiated as a package with the same objective, the amount of consideration to be paid in one contract depends on the price of performance of the other contract or the rights to use the underlying assets conveyed in the contracts are a single lease component. Lease components are considered separate if the Company can benefit from the right to use either on its own or together with other resources readily available to the Company and the right to use is not highly dependent or highly interrelated with the other rights to use the underlying assets in the contract. Consideration in the contract is allocated only to lease and non-lease components of a contract. The Company has elected the practical expedient allowing the Company to combine lease and non-lease components by class as a single lease component for its real estate leases. Nonlease components for the Company's vehicles and other equipment leases are not material. The lease term is the noncancellable period for which a lessee has the right to use an underlying asset, including periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option and periods covered by an option to terminate the lease if the lessee is reasonably certain not to exercise that option. For renewal options, the Company performs an assessment at commencement if it is reasonably likely to exercise the option. The assessment is based on the Company's intentions, past practices, estimates and factors that create an economic incentive for the Company. Generally, the Company is not reasonably certain to exercise the renewal option in a lease contract as it performs an assessment for most real estate leases within six months prior to termination comparing the renewal rents under the option with the fair market returns for equivalent property under similar terms and conditions. Although the Company does not historically change locations often, it is not reasonably certain the Company will exercise the renewal option; therefore, the periods covered by the renewal option are not typically included in the lease term at commencement. While some of the Company's leases include options allowing early termination of the lease, the Company historically has not terminated its lease agreements early unless there is an economic, financial or business reason to do so; therefore, the Company does not typically consider the termination option in its lease term at commencement. 3. SIGNIFICANT ACCOUNTING POLICIES UPDATE (CONTINUED) Leasing - continued Consideration in the contract is the sum of lease payments relating to the use of the underlying asset, fixed payments and other in-substance fixed payments, less any incentives received. Remeasurement of variable lease payments based on an index is only required if remeasurement is required for another reason, such as a change in lease term or change in estimates of probable payments under residual value guarantees. If remeasured, the remeasurement date becomes the new date for updating the payments based on the index. The Company uses the discount rate implicit in a lease contract, if available. As most of the Company's leases do not provide an implicit rate, the Company uses the incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. For any leases that existed prior to the adoption of the standard, the Company used the incremental borrowing rate as of January 1, 2019 based on the type of asset and term of the lease. The Company separated its real estate leases by classes of lease terms and used the incremental borrowing rate consistent with its lease term class to determine the present value of lease payments. As most of the Company's vehicles have a four-year lease term, the Company used the incremental borrowing rate consistent with a four-year lease term for all vehicles. For all other equipment leases, the Company used the incremental borrowing rate consistent with a five-year lease term as the majority of the Company's leases for other equipment have a five-year lease term.

SIGNIFICANT ACCOUNTING POLICIES UPDATE

The Company's significant accounting policies are detailed in Note 1, Summary of Significant Accounting Policies of its Annual Report on Form 10-K for the year-ended December 31, 2018. Significant changes to our accounting policies as a result of adopting new accounting standards are discussed below:

Leasing

Under Accounting Standards Codification ("ASC") 842, the Company determines if a contract contains a lease at the inception date of the contract. To determine if the contract contains a lease, the Company evaluates if there is an identified asset in the contract and if the Company has control over the use of the identified asset. There is an identified asset in the contract if the asset is explicitly or implicitly specified in the contract, the asset is physically distinct or the Company has the right to receive substantially all of the asset's capacity, and if the supplier does not have substantive substitution rights. The Company has control over the use of the identified asset if the Company obtains substantially all economic benefits from the use of the asset and can direct the use of the asset. The Company applied the practical expedient for any contracts that existed prior to January 1, 2019; therefore, the contracts were not reassessed to determine if they contain leases.

The Company must classify each lease as a finance lease or operating lease. A lease is classified as a finance lease if the Company will own the asset by the end of the lease term, the Company is reasonably certain to exercise the purchase option, the lease term covers a major part of the asset's economic life, the sum of the present value of the lease payments and the present value of the residual value guarantee not included in the lease payments equal or exceed substantially all of the fair value of the underlying asset at lease commencement or if the lessor has no alternative use for the asset. If any of these criteria are not met, the lease is classified as an operating lease. The Company applied the practical expedient for any leases that existed prior to January 1, 2019; therefore, the lease classifications of existing leases were not reassessed (all existing leases classified as operating leases under ASC 840 were classified as operating leases under ASC 842 on January 1, 2019 and all existing leases classified as capital leases under ASC 840 were classified as finance leases under ASC 842 on January 1, 2019).

The Company's operating leases consist of rent commitments under various leases for office space, warehouses, land and buildings at varying dates from January 2019 to June 2028. The terms of most of these leases are in the range of 3 to 10 years. Some of the Company's leases have fixed amount rent escalations, rent holidays or contingent rent that are recognized on a straight-line basis over the entire lease term. Material leasehold improvements and other landlord incentives are amortized over the shorter of their economic lives or the lease term, including renewal periods, if reasonably assured. Certain annual rentals are subject to renegotiation, with certain leases renewable for varying periods and certain leases including options to terminate the leases.

Substantially all real estate taxes, insurance and maintenance expenses associated with leased facilities are obligations of the Company. It is expected that in the normal course of business leases that expire will be renewed or replaced by leases on other similar property. The terms for most machinery and equipment leases range from 3 to 5 years.

Leasing - continued

The majority of the Company's finance leases consist of assets purchased under the Company's master leasing agreement with PNC Equipment Finance ("PNC"), and are included in machinery, office furniture and equipment and construction in process. At March 29, 2019, the Company's master leasing agreement with PNC had a maximum capacity of $20.0 million. The terms of these leases are 5 years. Amortization of these assets is included in depreciation and amortization expense.

At the commencement date, the right-of-use asset and lease liability are recorded to the Company's Condensed Consolidated Balance Sheets when the Company obtains control of the use of the asset. Right-of-use assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make payments upon entering into a lease agreement.

3. SIGNIFICANT ACCOUNTING POLICIES UPDATE (CONTINUED)

Leasing - continued

Consideration in the contract is the sum of lease payments relating to the use of the underlying asset, fixed payments and other in-substance fixed payments, less any incentives received. Remeasurement of variable lease payments based on an index is only required if remeasurement is required for another reason, such as a change in lease term or change in estimates of probable payments under residual value guarantees. If remeasured, the remeasurement date becomes the new date for updating the payments based on the index.

The Company uses the discount rate implicit in a lease contract, if available. As most of the Company's leases do not provide an implicit rate, the Company uses the incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. For any leases that existed prior to the adoption of the standard, the Company used the incremental borrowing rate as of January 1, 2019 based on the type of asset and term of the lease. The Company separated its real estate leases by classes of lease terms and used the incremental borrowing rate consistent with its lease term class to determine the present value of lease payments. As most of the Company's vehicles have a four-year lease term, the Company used the incremental borrowing rate consistent with a four-year lease term for all vehicles. For all other equipment leases, the Company used the incremental borrowing rate consistent with a five-year lease term as the majority of the Company's leases for other equipment have a five-year lease term.
