Accounting Policies | 2. Accounting Policies ​ The significant accounting policies used in preparation of these consolidated financial statements for the three and six months ended June 30, 2019 are consistent with those discussed in Note 2 of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, with the exception of the Company’s change in its accounting policy for Leases resulting from the adoption of ASC 842 as of January 1, 2019 described herein. ​ Leases ​ The Company has leases for the following classes of underlying assets: real estate, automobiles, manufacturing equipment, facility equipment, office equipment and certain service arrangements that are dependent on an identified asset. The Company determines if an arrangement qualifies as a lease at its inception. The Company, as the lessee, recognizes in the statement of financial position a liability to make lease payments and a right-of-use asset (“ROU”) representing the right to use the underlying asset for both finance and operating leases with a lease term longer than twelve months. The Company elected the short-term lease recognition exemption for all leases that qualify and does not recognize ROU assets or lease liabilities for short-term leases. The Company recognizes short-term lease payments on a straight-line basis over the lease term in the consolidated statement of operations. The Company determines the initial classification and measurement of its ROU assets and lease liabilities at the lease commencement date and thereafter if modified. For operating leases, the lease liability is initially and subsequently measured at the present value of the unpaid lease payments at the lease commencement date. For finance leases, the lease liability is initially measured in the same manner and date as for operating leases and is subsequently measured at amortized cost using the effective interest method. Measuring the lease liability requires certain estimates and judgements. These estimates and judgments include how the Company determines 1) the discount rate it uses to discount the unpaid lease payments to present value; 2) lease term; and 3) lease payments.
| ● | The present value of lease payments is determined using the interest rate implicit in the lease, if that rate is readily determinable; otherwise, the Company uses its incremental borrowing rate. Generally, the Company cannot determine the interest rate implicit in the lease because it does not have access to the lessor’s estimated residual value or the amount of the lessor’s deferred initial direct costs. Therefore, the Company uses the incremental borrowing rate as the discount rate for the lease. The Company’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under a similar term. The Company’s incremental borrowing rate is determined by using a portfolio approach by geographic region, considering many factors, such as the Company’s specific credit risk, the amount of the lease payments, collateralized nature of the lease, both borrowing term and the lease term, and geographical economic considerations.
| ● | The lease term for all of the Company’s leases includes the fixed, noncancelable term of the lease plus (a) all periods, if any, covered by options to extend the lease if the Company is reasonably certain to exercise that option, (b) all periods, if any, covered by an option to terminate the lease if the Company is reasonably certain not to exercise that option, and (c) all periods, if any, covered by an option to extend (or not to terminate) the lease in which exercise of the option is controlled by the lessor. When determining if a renewal option is reasonably certain of being exercised, the Company considers several economic factors, including but not limited to, the significance of leasehold improvements incurred on the property, whether the asset is difficult to replace, underlying contractual obligations, or specific characteristics unique to that particular lease that would make it reasonably certain to exercise such option.
| ● | Lease payments included in the measurement of the lease liability include the following:
| o | Fixed payments, including in-substance fixed payments, owed over the lease term (which includes termination penalties the Company would owe if the lease term assumes Company exercise of a termination option), less any lease incentives paid or payable to the Company;
| o | Variable lease payments that depend on an index or rate initially measured using the index or rate at the commencement date;
| o | Amounts expected to be payable under a Company-provided residual value guarantee;
| o | The exercise price of a Company option to purchase the underlying asset if the Company is reasonably certain to exercise that option; and
| o | Fees paid by the Company to the owners of a special purpose entity for structuring the transaction.
​ The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for the lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. For operating leases, the ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received. Lease expense for operating leases is recognized on a straight-line basis over the reasonably assured lease term based on the total lease payments and is included in cost of goods sold or within selling, general and administrative expenses in the consolidated statements of operations, based on the primary use of the ROU asset. For finance leases, the Company recognizes the amortization of the ROU asset on a straight-line basis from the lease commencement date to the earlier of the end of the useful life or the end of the lease term unless the lease transfers ownership of the underlying asset to the Company or the Company is reasonably certain to exercise an option to purchase the underlying asset. In those cases, the ROU asset is amortized over the useful life of the underlying asset. Amortization of the ROU asset is recognized in depreciation in the consolidated statements of operations. The interest expense related to finance leases is recognized using the effective interest method and is included within interest expense. Variable lease payments associated with the Company’s leases are recognized in the period when the event, activity, or circumstance in the lease agreement on which those payments are assessed occurs and are included in cost of goods sold or within selling, general and administrative expenses in the consolidated statements of operations, based on the primary use of the ROU asset. ROU assets for operating and finance leases are periodically reduced by impairment losses. The Company uses the long-lived assets impairment guidance in ASC Subtopic 360-10, Property, Plant, and Equipment- Overall, to determine whether an ROU asset is impaired, and if so, the amount of the impairment loss to recognize. The Company monitors for events or changes in circumstances that require a reassessment of one of its leases. When a reassessment results in a remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the corresponding ROU asset unless doing so would reduce the carrying amount of the ROU asset to an amount less than zero. In that case, the amount of the adjustment that would result in a negative ROU asset balance is recorded in the statement of operations. Recently Adopted Accounting Standards ​ In August 2017, the FASB issued ASU 2017-12 “Derivatives and Hedging (Topic 815)-Targeted Improvements to Accounting for Hedging Activities.” ASU 2017-12 amends the hedge accounting guidance to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in the financial statements. This guidance permits hedge accounting for risk components in hedging relationships that involve nonfinancial risk, reduces complexity in hedging for fair value hedges of interest rate risk, eliminates the requirement to separately measure and report hedging ineffectiveness, and simplifies certain hedge effectiveness assessment requirements. This standard is effective for fiscal years beginning after December 15, 2018, including interim periods within that reporting period. The Company adopted this standard in the first quarter of 2019, and it did not have a material impact on the Company’s financial statements. ​ In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 requires a lessee to recognize in the statement of financial position a liability to make lease payments and an ROU asset representing the right to use the underlying asset for the lease term for both finance and operating leases with a term longer than twelve months. Topic 842 was subsequently amended by ASU 2018-01, “Land Easement Practical Expedient for Transition to Topic 842,” ASU 2018-10, “Codification Improvements to Topic 842, Leases,” and ASU 2018-11 “Targeted Improvements.” ASU 2016-02 is effective for financial statements issued for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Under ASC 842, leases are classified as finance or operating, with the classification determining the pattern and classification of expense recognition in the income statement. ​ A modified retrospective transition approach was required, applying the new standard to all leases existing at the date of initial application. The Company could choose to use either 1) the effective date of the standard or 2) the beginning of the earliest comparable period presented in the financial statements as the date of initial application. The Company adopted the new standard on January 1, 2019 and used the effective date of the standard as the date of the Company’s initial application. By electing this approach, the financial information and the disclosures required under the new standard are not provided for dates and periods before January 1, 2019. The Company designed the necessary changes to its existing processes and configured all system requirements that were necessary to implement this new standard. The new standard provides a number of optional practical expedients throughout the transition. The Company elected the “package of practical expedients,” which permitted the Company to not reassess under the new standard the Company’s prior conclusions about lease identification, lease classification, and initial direct costs. The Company did not elect the use-of-hindsight or the practical expedient pertaining to land easements, the latter not being applicable to the Company. The Company also elected the practical expedient to not separate lease and non-lease components for all of the Company’s leases. As a result of adopting ASC 842, the Company recorded operating ROU assets of $33.6 million and operating lease liabilities of $33.9 million as of January 1, 2019 on the consolidated balance sheet. The difference between the ROU assets and lease liabilities related to the impact of eliminating deferred and prepaid lease payments recognized under the previous lease accounting standard. The Company’s adoption of ASC 842 did not result in a change to the Company’s recognition of its existing finance leases as of January 1, 2019. The adoption of the new lease accounting standard did not have a material impact on either the consolidated statement of operations or the consolidated statement of cash flows. However, ASU 2016-02 has significantly affected the Company’s disclosures about noncash activities related to leases. Additionally, the Company’s lease-related disclosures have significantly increased as of and for the period ended June 30, 2019 as compared to prior years. See Note 4 to the consolidated financial statements. ​ Shipping and Handling ​ Shipping and handling costs included in selling, general and administrative expenses amounted to $14.6 million and $14.7 million for the second quarters of 2019 and 2018, respectively, and were $28.5 million and $27.9 million for the first six months of 2019 and 2018, respectively. ​ Research and Development ​ Research and development costs included in selling, general and administrative expenses amounted to $9.5 million and $8.3 million for the second quarters of 2019 and 2018, respectively, and were $18.8 million and $16.8 million for the first six months of 2019 and 2018, respectively.
