Summary of Significant Accounting Policies (Policies) | 12 Months Ended
--- | ---
Dec. 31, 2019
Accounting Policies [Abstract] |
Nature of Operations | Nature of Operations Stepan Company (the Company) operations consist predominantly of the production and sale of specialty and intermediate chemicals, which are sold to other manufacturers for use in a variety of end products. Principal markets for all products are manufacturers of cleaning and washing compounds (including detergents, shampoos, fabric softeners, toothpastes and household cleaners), paints, cosmetics, food, beverages, nutritional supplements, agricultural products, plastics, furniture, automotive equipment, insulation and refrigeration.
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires Company 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 reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of the Company and all wholly and majority-owned subsidiaries in which the Company exercises controlling influence. The equity method is used to account for investments in which the Company exercises significant but noncontrolling influence. Intercompany balances and transactions are eliminated in consolidation. The Company has an 80 percent ownership interest in the Nanjing Stepan Jinling Chemical Limited Liability Company (a joint venture) and exercises controlling influence over the entity. Therefore, Nanjing Stepan Jinling Chemical Limited Liability Company’s accounts are included in the Company’s consolidated financial statements. The partner’s interest in the joint venture’s net income is reported in the net income attributable to noncontrolling interests line of the consolidated statements of income. The partner’s interest in the net assets of the joint venture is reported in the noncontrolling interests line (a component of equity separate from Company equity) of the consolidated balance sheets.
Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers all highly liquid investments with purchased maturities of three months or less to be cash equivalents. At December 31, 2019, the Company’s cash and cash equivalents totaled $315.4 million including $110.7 million in money market funds, each of which was rated AAAm by Standard and Poor’s, Aaa-mf by Moody’s and AAAmmf by Fitch. Cash in U.S. demand deposit accounts and certificates of deposit totaled $105.7 million and cash of the Company’s non-U.S. subsidiaries held outside the U.S. totaled $99.0 million as of December 31, 2019.
Receivables and Credit Risk | Receivables and Credit Risk Receivables are stated net of allowances for doubtful accounts and other allowances and primarily include trade receivables from customers, as well as nontrade receivables from suppliers, governmental tax agencies and others. The Company is exposed to credit risk on accounts receivable balances. This risk is mitigated by the Company’s large, diverse customer base, which is dispersed over various geographic regions and industrial sectors. No single customer comprised more than 10 percent of the Company’s consolidated net sales in 2019, 2018 or 2017. The Company maintains allowances for potential credit losses. Specific customer allowances are recorded when a review of customer creditworthiness and current economic conditions indicate that collection is doubtful. The Company also maintains other customer allowances that occur in the normal course of business. Such allowances are based on historical averages and trade receivable levels. The following is an analysis of the allowance for doubtful accounts and other accounts receivable allowances for the years ended December 31, 2019, 2018 and 2017:
(In thousands) |  | 2019 |  |  | 2018 |  |  | 2017 |
Balance at January 1 |  | $ | 9,654 |  |  | $ | 10,116 |  |  | $ | 9,755 |
Provision charged to income |  |  | 29 |  |  |  | 764 |  |  |  | 45 |
Accounts written off, net of recoveries |  |  | (358 | ) |  |  | (1,226 | ) |  |  | 316 |
Balance at December 31 |  | $ | 9,325 |  |  | $ | 9,654 |  |  | $ | 10,116 |
Inventories | Inventories Inventories are valued at cost, which is not in excess of market value, and include material, labor and plant overhead costs. Prior to 2019, the LIFO method was used to determine the cost of the Company’s U.S. inventories. Effective January 1, 2019, the Company elected to change its method of accounting for U.S. inventories from the LIFO basis to FIFO basis. Non-U.S. inventories have historically been maintained on the FIFO basis. Prior period financial statements have been adjusted to reflect what results would have been had the Company always used the FIFO method of inventory valuation for U.S. inventories. See Note 2 for additional details.
Property, Plant and Equipment | Property, Plant and Equipment Depreciation of property, plant and equipment is provided on a straight-line basis over the estimated useful lives of the assets. Lives used for calculating depreciation are generally 30 years for buildings and 15 years for building improvements. For assets classified as machinery and equipment, lives generally used for calculating depreciation expense range from 10 to 15 years for manufacturing equipment, five to 10 years for furniture and fixtures, three to five years for vehicles and three to 10 years for computer equipment and software. Manufacturing of chemicals is capital intensive and a large majority of the assets included within machinery and equipment represent manufacturing equipment. Major renewals and betterments are capitalized in the property accounts, while maintenance and repairs ($58,464,000, $57,010,000, and $51,926,000 in 2019, 2018 and 2017, respectively), which do not renew or extend the life of the respective assets, are charged to operations as incurred. Land is not depreciated. The cost of property retired or sold and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in income. Included in the computer equipment and software component of machinery and equipment are costs related to the acquisition and development of internal-use software. Capitalized costs for internal-use software include external direct costs of materials and services consumed in obtaining and developing the software. For development projects where major internal resources are committed, payroll and payroll-related costs incurred during the application development phase of the project are also capitalized. The capitalized costs are amortized over the useful lives of the software, which are generally three to 10 years. Costs incurred in the preliminary project phase are expensed. Interest charges on borrowings applicable to major construction projects are capitalized.
Fair Value Measurements | Fair Value Measurements GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Furthermore, GAAP establishes a framework, in the form of a three-level hierarchy, for measuring fair value that prioritizes the inputs to valuation techniques used to measure fair value. The following describes the hierarchy levels: Level 1 - quoted prices in active markets for identical assets and liabilities. Level 2 - inputs other than quoted prices included within Level 1 that are directly or indirectly observable for the asset or liability, such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 - unobservable inputs which reflect the entity’s own assumptions about the assumptions market participants use in pricing the assets and liabilities. The Company applies the fair value measurement provisions of GAAP to any of its financial assets and liabilities that are carried at fair value on the consolidated balance sheets (see Note 3), its outstanding debt for disclosure purposes (also Note 3) and its pension plan assets (see Note 14). The Company also applies the fair value measurement requirements to nonrecurring fair value measurements of nonfinancial assets and liabilities recorded in conjunction with business combinations and as part of impairment reviews for goodwill and other long-lived assets.
Revenue Recognition | Revenue Recognition The Company’s contracts typically have a single performance obligation that is satisfied at the time product is shipped and control passes to the customer. For a small portion of the business, performance obligations are deemed satisfied when product is delivered to a customer location. For arrangements where the Company consigns product to a customer location, revenue is recognized when the customer uses the inventory. The Company accounts for shipping and handling as activities to fulfill a promise to transfer a good. As such, shipping and handling fees billed to customers in a sales transaction are recorded in Net Sales and shipping and handling costs incurred are recorded in Cost of Sales. Volume and cash discounts due customers are estimated and recorded in the same period as the sales to which the discounts relate and are reported as reductions of revenue in the consolidated statements of income. See Note 22 to the consolidated financial statements for more details.
Cost of Sales | Cost of Sales Cost of sales comprises raw material costs (including inbound freight expense to deliver the raw materials), manufacturing plant labor expenses and various manufacturing overhead expenses, such as utility, maintenance, operating supply, amortization and manufacturing asset depreciation expenses. Cost of sales also includes outbound shipping and handling expenses, inter-plant transfer costs, warehouse expenses and rail car rental expenses.
Operating Expenses | Operating Expenses Selling expense comprises salary and the related fringe benefit expenses for marketing and sales personnel and operating costs, such as outside agent commissions, automobile rental and travel-related expenses, which support the sales and marketing functions. Bad debt charges and any depreciation expenses related to marketing assets (e.g., computers) are also classified as selling expense. Administrative expense comprises salary and the related fringe benefit expenses and operating costs for the Company’s various administrative functions, which include information services, finance, legal, and human resources. The majority of environmental remediation expenses are also classified as administrative expense. The Company’s research and development costs are expensed as incurred. These expenses are aimed at discovery and commercialization of new knowledge with the intent that such effort will be useful in developing a new product or in bringing about a significant improvement to an existing product or process. Total research and development expenses were $34,139,000, $33,519,000, and $33,169,000 in 2019, 2018 and 2017, respectively. The remainder of research, development and technical service expenses reflected on the consolidated statements of income relates to technical services, which include routine product testing, quality control and sales support service. Compensation expense or income related to the Company’s deferred compensation plans is presented in the deferred compensation expense (income) line in the Consolidated Statements of Income.
Environmental Expenditures | Environmental Expenditures Environmental expenditures that relate to current operations are expensed in cost of sales. Expenditures that mitigate or prevent environmental contamination and that benefit future operations are capitalized as assets and depreciated on a straight-line basis over the estimated useful lives of the assets, which are typically 10 years. Estimated future expenditures that relate to an existing condition caused by past operations, and which do not contribute to current or future revenue generation, are recorded as liabilities, with the corresponding charge typically recorded in administrative expenses, when environmental assessments and/or remedial efforts are probable and the cost or range of possible costs can be reasonably estimated. When no amount within the range is a better estimate than any other amount, the minimum amount in the range is accrued. Some of the factors on which the Company bases its estimates include information provided by feasibility studies, potentially responsible party negotiations and the development of remedial action plans. Legal costs related to environmental matters are expensed as incurred (see Note 17 for environmental contingencies).
Goodwill and Other Intangible Assets | Goodwill and Other Intangible Assets The Company’s intangible assets include patents, agreements not to compete, trademarks, customer lists and relationships, technological and manufacturing know-how, supply contracts and goodwill, all of which were acquired as part of business or product line acquisitions. Intangible assets other than goodwill are determined to have either finite or indefinite useful lives. The Company currently has no indefinite-life intangible assets other than goodwill. The values for intangible assets with finite lives are amortized over the useful lives of the assets. Currently, the useful lives for the Company’s finite-lived intangible assets are as follows: patents – 10-15 years; non-compete agreements – five years; trademarks – 11 years; customer relationships – 10-25 years; supply contracts – four years and know-how – 8-14 years. In addition, finite-life intangible assets are tested for impairment when events or changes in circumstances indicate that the carrying value of an intangible asset may not be recoverable. Goodwill is not amortized but is tested for impairment at least annually or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit to which goodwill relates below the reporting unit’s carrying value. See Note 5 for detailed information about goodwill and other intangible assets.
Income Taxes | Income Taxes Income taxes are accounted for under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. Deferred tax assets are recognized to the extent that we believe these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If we determine that we would be able to realize our deferred tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. Uncertain tax positions are recorded in accordance with ASC 740 on the basis of a two-step process whereby (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits within the income tax expense line in the accompanying Consolidated Statement of Operations. Accrued interest and penalties are included within the related tax liability line in the Consolidated Balance Sheet. See Note 10 for more information about the Company’s income taxes.
Translation of Foreign Currencies | Translation of Foreign Currencies For the Company’s consolidated foreign subsidiaries whose functional currency is the local foreign currency, assets and liabilities are translated into U.S. dollars at exchange rates in effect at year end and revenues and expenses are translated at average exchange rates for the year. Any resulting translation adjustments are included in the consolidated balance sheets in the accumulated other comprehensive loss line of stockholders’ equity. Gains or losses on foreign currency transactions are reflected in the other, net caption of the consolidated statements of income. The Company has three foreign subsidiaries whose functional currencies are the U.S. dollar. For these subsidiaries, nonmonetary assets and liabilities are translated at historical rates, monetary assets and liabilities are translated at exchange rates in effect at year end, revenues and expenses are translated at average exchange rates for the year and translation gains and losses are included in the other, net caption of the consolidated statements of income.
Stock-Based Compensation | Stock-Based Compensation The Company grants stock options, stock awards (including performance-based stock awards) and SARs to certain employees under its incentive compensation plans. The Company calculates the fair values of stock options, stock awards and SARs on the date such instruments are granted. The fair values of the stock options and stock awards are then recognized as compensation expense over the vesting periods of the instruments. The Company’s SARs granted before 2015 settle in cash. The cash-settled SARs are accounted for as liabilities that must be re-measured at fair value at the end of each reporting period. Compensation expense for each reporting period is calculated as the period-to-period change (or portion of the change, depending on the proportion of the vesting period that has been completed at the reporting date) in the fair value of the cash-settled SARs. SARs granted subsequent to 2014 are settled in shares of Company common stock. Compensation expense for the stock-settled SARs is calculated in the same way as compensation expense for stock options. See Note 12 for detailed information about the Company’s stock-based compensation.
Earnings Per Share | Earnings Per Share Basic earnings per share amounts are computed as net income attributable to the Company divided by the weighted-average number of common shares outstanding. Diluted earnings per share amounts are based on the weighted-average number of common shares outstanding plus the weighted-average of net common shares (under the treasury stock method) that would be outstanding assuming the exercise of outstanding stock options and stock-settled SARs, the vesting of unvested stock awards that have no performance or market condition and the issuance of contingent performance stock awards. See Note 19 for detailed information about the Company’s earnings per share calculations.
Comprehensive Income and Accumulated Other Comprehensive Income | Comprehensive Income and Accumulated Other Comprehensive Income Comprehensive income includes net income and all other non-owner changes in equity that are not reported in net income. Comprehensive income is disclosed in the consolidated statements of comprehensive income. Accumulated other comprehensive income (AOCI) is reported as a component of stockholders’ equity in the Company’s consolidated balance sheets. See Note 20 for detailed information regarding changes in the Company’s AOCI and reclassifications out of AOCI to income.
Segment Reporting | Segment Reporting The Company reports financial and descriptive information about its reportable operating segments. Operating segments are components of the Company that have separate financial information that is regularly evaluated by the chief operating decision maker to assess segment performance and allocate resources. The Company discloses segment revenue, operating income, assets, capital expenditures and depreciation and amortization expenses. Enterprise-wide financial information about the geographic locations in which the Company earns revenues and holds assets is also disclosed. See Note 18 for detailed information about the Company’s segment reporting.
Derivative Instruments | Derivative Instruments Derivative instruments are recognized in the consolidated balance sheets as either assets or liabilities measured at fair value. For derivative instruments that are not designated as hedging instruments, changes in the fair values of the derivative instruments are recognized currently in earnings. For derivative instruments designated as hedging instruments, depending on the nature of the hedge, changes in the fair values of the derivative instruments are either offset in earnings against changes in the fair values of the hedged items or recognized in AOCI until the hedged transaction is recognized in earnings. At the time a hedging relationship is designated, the Company establishes the method it will use for assessing the effectiveness of the hedge and the measurement approach for determining the ineffective aspect of the hedge. Company policy prohibits the use of derivative instruments for trading or speculative purposes. See Note 4 for further information regarding the Company’s use of derivatives. At December 31, 2019, the Company held open forward contracts for the purchase of 0.9 million dekatherms of natural gas in 2020 at a cost of $2,442,000. The Company uses forward contracts to minimize its exposure to volatile natural gas prices. Because the Company anticipates taking delivery of the natural gas for use in its operations, the forward contracts qualify for the normal purchase exception provided under U.S. GAAP for derivative instruments. The Company has elected the exception for such contracts. As a result, the forward contracts are not accounted for as derivative instruments. The cost of natural gas is charged to expense at the time the natural gas is delivered and used.
Recent Accounting Pronouncements | Recent Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-2, Leases (Topic 842). This guidance requires a dual approach for lessee accounting whereby a lessee will account for lease arrangements with terms greater than 12 months as either finance leases or operating leases. Both finance leases and operating leases are recognized on the lessee’s balance sheet as right-of-use assets and corresponding lease liabilities, with differing methodologies for income statement recognition. In addition, the ASU requires expanded qualitative and quantitative disclosures about the Company’s lease arrangements. This guidance is effective for public business entities for fiscal years, and interim periods within those years, beginning after December 15, 2018. The most significant impact of ASU No. 2016-2, Leases (Topic 842) is that a lessee is required to recognize a “right-of-use” asset and corresponding lease liability for operating leases agreements. The Company adopted the new lease standard on January 1, 2019 by recognizing lease assets and the corresponding lease liabilities. The adoption of these guidelines did not have an impact on retained earnings, the Company’s results of operations or cash flows, but it did have a material impact on specific balance sheet line items. See Note 8, Leases for more details. In February 2018, the FASB issued ASU No. 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which permits a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. Consequently, the update reclassifies the stranded tax effects resulting from the Tax Act and should improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Act, the underlying guidance that requires that the effects of the change in tax laws or rates be included in income from continuing operations is not affected. The amendments in this update also require certain disclosures about stranded tax effects. This update is effective for public business entities for fiscal years, and interim periods within those years, beginning after December 15, 2018. The Company adopted this guidance and recorded a $5,325,000 adjustment to the opening balance of retained earnings as of January 1, 2019 with the corresponding offset to AOCI. See Note 20, Accumulated Other Comprehensive Income (Loss) for more details. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments which amends the guidance on the measurement of the impairment of financial instruments. The new pronouncement replaces the existing model of measuring credit losses with an expected credit loss model referred to as “the Current Expected Credit Loss (CECL) model.” The new model is based on expected losses that should be measured based not only on historical experience but on the combination of historical data, current conditions and reasonable forecasts. Under this methodology, an entity recognizes as an allowance its estimate of lifetime expected credit losses and is required to apply the new credit loss model to most financial instruments held at amortized cost including trade receivables. The amendments in the update are effective for fiscal years, and interim periods within fiscal years, beginning after December 15, 2019. The adoption of the guidance in ASU No. 2016-13 will not have a material effect on the Company’s financial position, results of operations or cash flows. In January 2017, the FASB issued ASU No. 2017-4, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which eliminates Step 2 from the goodwill impairment test. When an indication of impairment was identified after performing the first step of the goodwill impairment test, Step 2 required that an entity determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) using the same procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Under the amendments in ASU No. 2017-4, an entity would perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying value. An entity would recognize an impairment charge for the amount by which the carrying value exceeds the reporting unit’s fair value. In addition, an entity must consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The Company is required to adopt the amendments in ASU No. 2017-4 for its annual, or any interim, goodwill impairment tests in fiscal years beginning after December 15, 2019. The adoption of the guidance in ASU No. 2017-4 in 2020 is not expected to have a material effect on the Company’s financial position, results of operations or cash flows. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. This update modifies some disclosure requirements related to fair value measurements used for different levels of instruments in fair value hierarchy (Level 1, Level 2 and Level 3). The amendments in the update are effective for fiscal years, and interim periods within fiscal years, beginning after December 15, 2019. The adoption of this update is not expected to have an effect on the Company’s financial position, results of operations and cash flows but may impact the disclosures made for fair value measurements used by the Company. In August 2018, the FASB issued ASU No. 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20). This update removes some disclosures about defined benefit plans that are no longer considered cost beneficial and adds some disclosures that have been identified as relevant. The amendments in this update are effective for fiscal years ending after December 15, 2020. The adoption of this update is not expected to have an effect on the Company’s financial position, results of operations and cash flows but will impact the disclosures made for the Company’s defined benefit retirement plans. In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use software (Subtopic 350-40) Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. This update aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This update requires the entity to determine which implementation costs to capitalize as an asset related to the service contacts and which costs to expense over the term of the hosting contract. The amendments in this update are effective for fiscal years beginning after December 15, 2019. The Company has elected to apply the update prospectively to eligible implementation costs incurred starting January 1, 2020. The adoption of the guidance in ASU No. 2018-15 will not have a material effect on the Company’s financial position, results of operations or cash flows. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes. This update provides guidance to reduce complexity in certain areas of accounting for income taxes. The amendments in this update are effective for fiscal years beginning after December 15, 2020. The adoption of this update is not expected to have a material effect on the Company’s financial position, results of operations and cash flows.
