3. FAIR VALUE MEASUREMENTS

The following describe the financial instruments held by the Company at September 30, 2017, and December 31, 2016, and the methods and assumptions used to estimate the instruments’ fair values:

Cash and cash equivalents

Carrying value approximated fair value because of the short maturity of the instruments.

Derivative assets and liabilities

Derivative assets and liabilities included the foreign currency exchange contracts are discussed in Note 4.  Fair value and carrying value were the same because the contracts were recorded at fair value.  The fair values of the foreign currency contracts were calculated as the difference between the applicable forward foreign exchange rates at the reporting date and the contracted foreign exchange rates multiplied by the contracted notional amounts.  See the table that follows the financial instrument descriptions for the reported fair values of derivative assets and liabilities.

Long-term investments

Long-term investments included the mutual fund assets the Company held to fund a portion of its deferred compensation liabilities and all of its non-qualified supplemental executive defined contribution obligations. Fair value and carrying value were the same because the mutual fund assets were recorded at fair value. Fair values for the mutual funds were calculated using the published market price per unit at the reporting date multiplied by the number of units held at the reporting date.  See the table that follows the financial instrument descriptions for the reported fair value of long-term investments.

Debt obligations

The fair value of debt with original maturities greater than one year comprised the combined present values of scheduled principal and interest payments for each of the various loans, individually discounted at rates equivalent to those which could be obtained by the Company for new debt issues with durations equal to the average life to maturity of each loan.  The fair values of the remaining Company debt obligations approximated their carrying values due to the short-term nature of the debt.  The Company’s fair value measurements for debt fall in level 2 of the fair value hierarchy.

At September 30, 2017, and December 31, 2016, the fair values of debt and the related carrying values, including current maturities, were as follows (the fair value and carrying value amounts are presented without regard to unamortized debt issuance costs of $1,025,000  and $1,141,000 as of September 30, 2017 and December 31, 2016, respectively):

(In thousands)	September 30, 2017		December 31, 2016
Fair value	$	309,587	$	316,364
Carrying value		305,451		318,154

The following tables present financial assets and liabilities measured on a recurring basis at fair value as of September 30, 2017, and December 31, 2016, and the level within the fair value hierarchy in which the fair value measurements fall:

4. DERIVATIVE INSTRUMENTS

The Company is exposed to certain risks relating to its ongoing business operations. The primary risk managed by the use of derivative instruments is foreign currency exchange risk.  The Company holds forward foreign currency exchange contracts that are not designated as any type of accounting hedge as defined by GAAP.  The Company uses these contracts to manage its exposure to exchange rate fluctuations on certain Company subsidiary cash, accounts receivable, accounts payable and other obligation balances that are denominated in currencies other than the entities’ functional currencies. The forward foreign exchange contracts are recognized on the balance sheet as either an asset or a liability measured at fair value. Gains and losses arising from recording the foreign exchange contracts at fair value are reported in earnings as offsets to the losses and gains reported in earnings arising from the re-measurement of the asset and liability balances into the applicable functional currencies. At September 30, 2017, and December 31, 2016, the Company had open forward foreign currency exchange contracts, all with durations of approximately one to three months, to buy or sell foreign currencies with U.S. dollar equivalent amounts of $39,220,000 and $33,372,000, respectively.

The fair values of the derivative instruments held by the Company on September 30, 2017, and December 31, 2016, are disclosed in Note 3. Derivative instrument gains and losses for the three- and nine-month periods ended September 30, 2017 and 2016, were immaterial.  For amounts reclassified out of accumulated other comprehensive income (loss) (AOCI) into earnings for the three- and nine-month periods ended September 30, 2017 and 2016, see Note 10.

5. STOCK-BASED COMPENSATION

On September 30, 2017, the Company had stock options outstanding under its 2006 Incentive Compensation Plan and stock options, stock awards and SARs outstanding under its 2011 Incentive Compensation Plan.  SARs granted prior to 2015 are cash-settled, and SARs granted in 2015 and thereafter are settled in shares of Company common stock.  Stock options and SARs granted prior to 2017 cliff vest after two years. Stock options and SARs granted in 2017 have a three-year graded vesting feature, with one-third of the awards vesting each year.  The Company has elected the straight-line method of expense attribution for the stock options and SARs with the graded vesting feature.

Compensation expense recorded for all stock options, stock awards and SARs was as follows:

(In thousands)
Three Months Ended September 30				Nine Months Ended September 30
2017		2016		2017		2016
$	1,697	$	3,607	$	6,248	$	8,055

The decrease in stock-based compensation expense between the three-month periods ended September 30, 2017 and 2016, was primarily attributable to a decrease in cash-settled SARs compensation resulting from a decrease in the market price of Company common stock in the third quarter of 2017 versus an increase in the stock price of Company common stock in the third quarter of 2016. The above decrease in cash-settled SARs compensation was also the primary reason for the decline in stock-based compensation expense between the nine-month periods ended September 30, 2017 and 2016.

Unrecognized compensation costs for stock options, stock awards and SARs were as follows:

(In thousands)	September30, 2017		December 31, 2016
Stock options	$	1,533	$	895
Stock awards		4,632		5,514
SARs		3,178		1,859

The unrecognized compensation costs at September 30, 2017, are expected to be recognized over weighted-average periods of 2.0 years, 1.6 years and 2.0 years for stock options, stock awards and SARs, respectively.

8

Grants of the following awards were made during the nine months ended September 30, 2017:

	Shares
Stock options		71,434
Stock awards (at target)		44,599
SARs		148,723

6. INVENTORIES

The composition of inventories at September 30, 2017, and December 31, 2016, was as follows: 

(In thousands)	September 30, 2017		December 31, 2016
Finished goods	$	106,881	$	127,597
Raw materials		56,835		46,066
Total inventories	$	163,716	$	173,663

Inventories are priced primarily using the last-in, first-out inventory valuation method.  If the first-in, first-out inventory valuation method had been used for all inventories, total inventory balances would have been approximately $33,606,000  and $25,872,000 higher than reported at September 30, 2017, and December 31, 2016, respectively.

7. CONTINGENCIES

There are a variety of legal proceedings pending or threatened against the Company.  Some of these proceedings may result in fines, penalties, judgments or costs being assessed against the Company at some future time.  The Company’s operations are subject to extensive local, state and federal regulations, including the U.S. Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA) and the Superfund amendments of 1986 (Superfund) and similar laws in the other countries in which the Company does business.  Over the years, the Company has received requests for information related to or has been named by the government as a potentially responsible party (PRP) at a number of waste disposal sites where cleanup costs have been or may be incurred under CERCLA and similar state statutes.  In addition, damages are being claimed against the Company in general liability actions for alleged personal injury or property damage in the case of some disposal and plant sites.  The Company believes that it has made adequate provisions for the costs it may incur with respect to these sites.

As of September 30, 2017, the Company estimated a range of possible environmental and legal losses of $25.0 million to $46.1million.  At September 30, 2017, and December 31, 2016, the Company’s accrued liability for such losses, which represented the Company’s best estimate within the estimated range of possible environmental and legal losses, was $25.0 million and $25.8 million, respectively. During the nine-month period ended September 30, 2017, cash outlays related to legal and environmental matters approximated $1.4 million compared to $1.0 million for the same period in 2016.

For certain sites, the Company has responded to information requests made by federal, state or local government agencies but has received no response confirming or denying the Company’s stated positions. As such, estimates of the total costs, or range of possible costs, of remediation, if any, or the Company’s share of such costs, if any, cannot be determined with respect to these sites. Consequently, the Company is unable to predict the effect thereof on the Company’s financial position, cash flows and results of operations.  Based upon the Company’s present knowledge with respect to its involvement at these sites, the possibility of other viable entities’ responsibilities for cleanup, and the extended period over which any costs would be incurred, the Company believes that these matters, individually and in the aggregate, will not have a material effect on the Company’s financial position.  However, in the event of one or more adverse determinations with respect to such sites in any annual or interim period, the effect on the Company’s cash flows and results of operations for those periods could be material.

Following are summaries of the material contingencies at September 30, 2017:

Maywood, New Jersey Site

The Company’s property in Maywood, New Jersey and property formerly owned by the Company adjacent to its current site and other nearby properties (Maywood site) were listed on the National Priorities List in September 1993 pursuant to the provisions of CERCLA because of certain alleged chemical contamination.  Pursuant to an Administrative Order on Consent entered into between United States Environmental Protection Agency (USEPA) and the Company for property formerly owned by the Company, and the issuance of an order by USEPA to the Company for property currently owned by the Company, the

9

Company has completed various Remedial Investigation Feasibility Studies, and on September 24, 2014, USEPA issued its Record of Decision (ROD) for chemically-contaminated soil. USEPA has not yet issued a ROD for chemically-contaminated groundwater for the Maywood site. Based on the most current information available, the Company believes its recorded liability represents its best estimate of the cost of remediation for the Maywood site. The best estimate of the cost of remediation for the Maywood site could change as the Company continues to hold discussions with USEPA, as the design of the remedial action progresses or if other PRPs are identified. The ultimate amount for which the Company is liable could differ from the Company’s current recorded liability.

In April 2015, the Company entered into an Administrative Settlement Agreement and Administrative Order on Consent with USEPA which requires payment of certain costs and performance of certain investigative and design work for chemically-contaminated soil.  Based on the Company’s review and analysis of this order, no changes to the Company’s recorded liability for claims associated with soil remediation of chemical contamination were required.  

In addition, under the terms of a settlement agreement reached on November 12, 2004, the U.S. Department of Justice and the Company agreed to fulfill the terms of a Cooperative Agreement reached in 1985 under which the United States will take title to and responsibility for radioactive waste removal at the Maywood site, including past and future remediation costs incurred by the United States.  As such, the Company recorded no liability related to this settlement agreement.

D’Imperio Property Site

During the mid-1970’s, Jerome Lightman and the Lightman Drum Company disposed of hazardous substances at several sites in New Jersey.  The Company was named as a PRP in a lawsuit in the U.S. District Court for the District of New Jersey that involved the D’Imperio Property Site located in New Jersey.  In 2016, the PRPs were provided with updated remediation cost estimates which were considered in the Company’s determination of its range of estimated possible losses and liability balance.  The changes in range of possible losses and liability balance were immaterial.  Remediation work is continuing at this site.  Based on current information, the Company believes that its recorded liability represents its best estimate of the cost of remediation for the D’Imperio site.  Depending on the ultimate cost of the remediation at this site, the amount for which the Company is liable could differ from the current estimates.

Wilmington Site

The Company is currently contractually obligated to contribute to the response costs associated with the Company’s formerly-owned site at 51 Eames Street, Wilmington, Massachusetts.  Remediation at this site is being managed by its current owner, to whom the Company sold the property in 1980.  Under the agreement, once total site remediation costs exceed certain levels, the Company is obligated to contribute up to five percent of future response costs associated with this site with no limitation on the ultimate amount of contributions. To date, the Company has paid the current owner $2.5 million for the Company’s portion of environmental response costs. The Company has recorded a liability for its portion of the estimated remediation costs for the site.  The Company believes that based on current information its recorded liability represents the best estimate of its share of the remediation costs at this site. Depending on the ultimate cost of the remediation at this site, the amount for which the Company is liable could differ from the current recorded liability.

The Company and other prior owners also entered into an agreement in April 2004 waiving certain statute of limitations defenses for claims which may be filed by the Town of Wilmington, Massachusetts, in connection with this site.  While the Company has denied any liability for any such claims, the Company agreed to this waiver while the parties continue to discuss the resolution of any potential claim which may be filed.

Other U.S. Sites

Through the regular environmental monitoring of its plant production sites, the Company discovered levels of chemical contamination that were above thresholds allowed by law at two of its U.S. plants.  The Company voluntarily reported its results to the applicable state environmental agencies.  As a result, the Company is required to perform self-remediation of the affected areas.  In the fourth quarter of 2016, the Company established a liability for the estimated cost of remediating the sites.  Based on current information, the Company believes that its recorded liability represents its best estimate of the cost of remediation for these sites.  The ultimate cost of the remediation at this site could differ from the Company’s current recorded liability.

8. POSTRETIREMENT BENEFIT PLANS

Defined Benefit Pension Plans

The Company sponsors various funded qualified and unfunded non-qualified defined benefit pension plans, the most significant of which cover employees in the U.S. and U.K. locations.  The U.S. and U.K. defined benefit pension plans are frozen and service benefits are no longer being accrued.

Employer Contributions

U.S. Plans

The Company made a $2,100,000 voluntary contribution to its funded U.S. qualified defined benefit plans in the three- and nine-month periods ended September 30, 2017. No other contributions are expected to be made to the funded plans in 2017. Approximately $312,000 is expected to be paid related to the unfunded non-qualified plans in 2017. Of such amount, $256,000 had been paid as of September 30, 2017.

U.K. Plan

The Company’s U.K. subsidiary expects to contribute approximately $360,000 to its defined benefit pension plan in 2017.  Of such amount, $281,000 had been contributed as of September 30, 2017.

Defined Contribution Plans

The Company sponsors retirement savings defined contribution plans that cover U.S. and U.K. employees. The Company also sponsors a qualified profit sharing plan for its U.S. employees. The retirement savings and profit sharing defined contribution plans include a qualified plan and a non-qualified supplemental executive plan.

Defined contribution plan expenses for the Company’s retirement savings and profit sharing plans were as follows:

(In thousands)	Three Months Ended September 30				Nine Months Ended September 30
	2017		2016		2017		2016
Retirement savings plans	$	1,275	$	1,304	$	3,758	$	3,849
Profit sharing plan		1,308		1,595		5,259		5,098
Total  defined contribution expense	$	2,583	$	2,899	$	9,017	$	8,947

The Company funds the obligations of its non-qualified supplemental executive defined contribution plans (supplemental plans) through a rabbi trust. The trust comprises various mutual fund investments selected by the participants of the supplemental plans. In accordance with the accounting guidance for rabbi trust arrangements, the assets of the trust and the obligations of the supplemental plans are reported on the Company’s consolidated balance sheets.  The Company elected the fair value option for the mutual fund investment assets so that offsetting changes in the mutual fund values and defined contribution

11

plan obligations would be recorded in earnings in the same period. Therefore, the mutual funds are reported at fair value with any subsequent changes in fair value recorded in the consolidated statements of income. The liabilities related to the supplemental plans increase (i.e., supplemental plan expense is recognized) when the value of the trust assets appreciates and decrease when the value of the trust assets declines (i.e., supplemental plan income is recognized). At September 30, 2017, the balance of the trust assets was $1,502,000, which equaled the balance of the supplemental plan liabilities.

9. EARNINGS PER SHARE

Below are the computations of basic and diluted earnings per share for the three and nine months ended September 30, 2017 and 2016:

The Company has a committed $125,000,000 multi-currency revolving credit agreement that expires on July 10, 2019.  The Company maintains standby letters of credit under its workers’ compensation insurance agreements and for other purposes, as needed from time to time, which are issued under the revolving credit agreement. As of September 30, 2017, the Company had outstanding letters of credit totaling $4,677,000 and no outstanding borrowing under the revolving credit agreement. There was $120,323,000 available under the revolving credit agreement as of September 30, 2017.

The various loan agreements contain provisions which, among others, require maintenance of certain financial ratios and place limitations on additional debt, investments and payment of dividends. Based on the loan agreement provisions that place limitations on dividend payments, unrestricted retained earnings (i.e., retained earnings available for dividend distribution) were $200,112,000 and $157,606,000 at September 30, 2017 and December 31, 2016, respectively.

14. BUSINESS RESTRUCTURING

In May 2016, the Company announced plans to shut down its Longford Mills, Ontario, Canada (Longford Mills) manufacturing facility, a part of the Surfactant reportable segment, by December 31, 2016. The shutdown plan was developed as an effort to improve the Company’s asset utilization in North America and to reduce the Company’s fixed cost base. Manufacturing operations of the Longford Mills plant ceased by the end of 2016, and production of goods manufactured at the facility was transferred to other Company North American production sites. Decommissioning of the assets is expected to continue throughout the remainder of 2017. As of September 30, 2017, an aggregate of $4,483,000 of expense has been recognized since the beginning of the restructuring, reflecting $1,594,000 of termination benefits for approximately 30 employees and $2,889,000 for other expenses, principally asset decommissioning costs. The spending for the decommissioning of the assets is nearly complete. 

Below is a reconciliation of the December 31, 2016 and the September 30, 2017 restructuring liabilities:

(In thousands)	Termination Benefits			Other Expense			Total
Restructuring liability at December 31, 2016	$	1,548		$	437		$	1,985

Foreign currency translation		37			14			51
Restructuring liability at September 30, 2017	$	778		$	139		$	917

In addition to the above, the Company eliminated 11 positions from manufacturing operations at its Singapore plant in June 2017. The Singapore plant is part of the Company’s Surfactant segment. The reduction in positions was made to better align the number of personnel with current business requirements and to reduce costs at that site. As a result of the reduction in workforce, termination expense of $132,000 was recognized in the second quarter ended June 30, 2017. As of September 30, 2017, there was no remaining liability for the termination pay.

15. ACQUISITIONS

2017 Acquisition Agreement

On June 13, 2017, the Company announced that it had reached an agreement with BASF Mexicana, S.A. DE C.V. (BASF) to acquire BASF’s production facility in Ecatepec, Mexico, and a portion of its related surfactants business. The facility, which is near Mexico City, has over 50,000 metric tons of capacity, 124,000 square feet of warehouse space, a laboratory and office space. The acquisition is currently expected to be completed in the first quarter of 2018, subject to closing conditions.  The acquired facility and business will be included in the Company’s Surfactant segment.

2016 Business Acquisition

On October 3, 2016, the Company’s subsidiary in Brazil acquired the commercial business of Tebras Tensoativos do Brazil Ltda. (Tebras) and the sulfonation production facility of PBC Industria Quimica Ltda. (PBC). The acquired businesses are included in the Company’s Surfactants segment. The original purchase price of the acquisitions was R$93,309,000 (approximately $29,075,000), of which R$70,000,000 (approximately $21,812,000) was paid from cash on hand, R$9,000,000 (approximately $2,804,000) was deposited in escrow to cover certain potential losses as specified in the purchase agreement and R$14,309,000 (approximately $4,459,000) for working capital adjustments was unpaid pending agreement on the adjustment amounts.

16

In the first quarter of 2017, the Company settled on and paid the working capital adjustment amounts that were outstanding at December 31, 2016. The payment totaled R$13,925,000 (approximately $4,339,000), which made the adjusted purchase price of the acquisitions R$92,925,000 (approximately $28,955,000).

As a result of the change in purchase price, the amount of the purchase price allocated to goodwill changed from $14,327,000 to $14,207,000. The values of all other assets acquired and liabilities assumed remained as previously reported. In addition, the change in purchase price had no impact on the Company’s current or previously reported results of operations. The following table summarizes the assets acquired and liabilities assumed:

(In thousands)
Assets:
Current assets	$	5,165
Property, plant and equipment		5,716
Identifiable intangible assets		7,354
Goodwill		14,207
Total assets acquired	$	32,442
Liabilities:
Current liabilities	$	408
Deferred tax liability		3,079
Total liabilities assumed	$	3,487
Net assets acquired	$	28,955

The acquired goodwill, which was assigned entirely to the Company’s Surfactant segment, is not currently tax deductible. The goodwill reflects the opportunity of introducing the Company’s broad line of surfactant products to the acquired entities’ large customer base. Identifiable intangible assets included customer relationships ($4,331,000), a supply contract ($2,555,000) and non-compete agreements ($468,000). The amortization period for these intangibles at the time of acquisition were 13 years, four years and five years, respectively. The Company continues to evaluate the purchase price allocation, including the estimated fair values of assets acquired and liabilities assumed. Any changes to these amounts during the measurement period may result in an adjustment to the recorded amount of goodwill.

16. RECENT ACCOUNTING PRONOUNCEMENTS

In May 2014, the Financial Accounting Standards Board (FASB) issued ASU No. 2014-9, Revenue from Contracts with Customers (Topic 606). The new update was later amended by ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. In addition, the ASU requires expanded disclosures about revenue recognition that enable the users of the financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. ASU No. 2014-09 supersedes most of the previous revenue recognition guidance. For public entities, the new guidance, as amended, is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. An entity may use either a full retrospective or a modified retrospective approach to adopt the requirements of the new standard. The Company expects to apply the modified retrospective approach. Although the Company continues the process of determining the effects, if any, that adoption of ASU No. 2014-9 will have on Company financial statements, adoption of the new guidance is not currently expected to have a material effect on the Company’s financial position, results of operations and cash flows. However, adoption of ASU No. 2014-9 is expected to affect the Company’s disclosures by requiring further disaggregation of revenue and additional insight about performance obligations.

  In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory, which requires an entity to measure inventory within the scope of the update at the lower of cost and net realizable value. Prior guidance required inventory to be measured at the lower of cost or market. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent measurement is unchanged for inventory measured using the last-in, first-out method or the retail inventory method. For public entities, ASU No. 2015-11 is effective prospectively for annual periods beginning after December 15, 2016, and interim periods therein. On January 1, 2017, the Company adopted ASU No. 2015-11, which did not have a material effect on the Company’s financial position, results of operations or cash flows.

In February 2016, the 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 will be 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

17

effective for public business entities for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. A modified retrospective approach is required for all leases existing or entered into after the beginning of the earliest comparative period in the consolidated financial statements. Most of the Company’s operating leases will be required to be placed on the balance sheet. The Company is assessing the quantitative impact that adoption of ASU No. 2016-2 will have on its financial position, results of operations and cash flows.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which adds or clarifies guidance on the classification of eight specific types of cash flows. The update is intended to reduce the existing diversity in practice with respect to the specific cash flow items. The amendments in ASU No. 2016-15 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company is assessing the impact that adoption of ASU No. 2016-15 will have on its cash flow presentation. ASU No. 2016-15 is not expected to have an effect on the Company’s financial position or results of operations.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. The update requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Current accounting guidance prohibits the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset has been sold to an outside party. The amendments in ASU No. 2016-16 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted for all entities as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued or made available for issuance.  The amendments in this update will be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company is assessing the impact that adoption of ASU No. 2016-16 will have on its financial position, results of operations and 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 amendments in ASU No. 2017-4 for annual, or any interim, goodwill impairment tests will be effective for fiscal years beginning after December 15, 2019. It is not expected that the adoption of the guidance in ASU No. 2017-4 will have a material effect on the Company’s financial position, results of operations or cash flows.

In March 2017, the FASB issued ASU No. 2017-7, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which amends existing guidance for the income statement presentation of the components of net periodic benefit cost for an entity’s sponsored defined benefit pension and other postretirement plans. The amended guidance requires entities to include the current service component of net periodic benefit cost in employee compensation costs in the income statement and to include all other components elsewhere in the income statement outside of income from operations. In addition, only the service cost component of net benefit cost is eligible for capitalization. For the Company, ASU No. 2017-7 is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted as of the beginning of any annual period for which an entity’s financial statements have not been issued. The requirements for the separate presentation of the service cost component and the other components of net periodic benefit cost must be adopted on a retrospective basis. The requirement to capitalize only the service component of net periodic benefit cost must be adopted on a prospective basis. Adoption of ASU No. 2017-7 will affect the presentation of the Company’s results of operations but will not have a material effect on the Company’s financial position or cash flows.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which amends previous guidance regarding hedge accounting recognition and presentation requirements. The updated guidance alters the hedge accounting model to make achieving hedge accounting easier for an entity and to have such accounting better reflect an entity’s risk management activities. ASU No. 2017-12 also adds new, and amends previous, disclosure requirements. For the Company, ASU No. 2017-12 is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. Entities must apply a modified retrospective approach to existing hedging relationships as of the adoption date. At present, because the Company has not entered into any transactions designated as accounting hedges, adoption of ASU No. 2017-12 is not expected to have a material effect on the Company’s financial position, results of operations and cash flows.

Item 2 - Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following is management’s discussion and analysis (MD&A) of certain significant factors that have affected the Company’s financial condition and results of operations during the interim periods included in the accompanying condensed consolidated financial statements.

Certain statements in this Quarterly Report on Form 10-Q, other than purely historical information, are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the Exchange Act). These statements include statements about Stepan Company’s and its subsidiaries’ (the Company) plans, objectives, strategies, financial performance and outlook, trends, the amount and timing of future cash distributions, prospects or future events and involve known and unknown risks that are difficult to predict. As a result, the Company’s actual financial results, performance, achievements or prospects may differ materially from those expressed or implied by these forward-looking statements. In some cases, forward-looking statements can be identified by the use of words such as “may,” “could,” “expect,” “intend,” “plan,” “seek,” “anticipate,” “believe,” “estimate,” “guidance,” “predict,” “potential,” “continue,” “likely,” “will,” “would,” “should,” “illustrative” and variations of these terms and similar expressions, or the negative of these terms or similar expressions. Such forward-looking statements are necessarily based upon estimates and assumptions that, while considered reasonable by the Company and its management based on their knowledge and understanding of the business and industry, are inherently uncertain. These statements are not guarantees of future performance, and stockholders should not place undue reliance on forward-looking statements. There are a number of risks, uncertainties and other important factors, many of which are beyond the Company’s control, that could cause the Company’s actual results to differ materially from the forward-looking statements contained in this Quarterly Report on Form 10-Q. Such risks, uncertainties and other important factors, include, among others, the risks, uncertainties and factors set forth under “Part I-Item IA. Risk Factors” in the Company’s 2016 Annual Report on Form 10-K: the risks and uncertainties related to disruptions in production or accidents at, or loss of, any of the Company’s manufacturing facilities; global competition and the Company’s ability to successfully compete; volatility of raw material, natural gas and electricity costs as well as any disruption in their supply; disruptions in transportation or significant changes in transportation costs; reduced demand for Company products due to customer product reformulations or new technologies; the Company’s ability to make acquisitions of suitable candidates and successfully integrate acquisitions; the Company’s ability to keep and protect its intellectual property rights; international business risks, including fluctuations in currency exchange rates, legal restrictions and taxes; potentially adverse tax consequences due to the international scope of the Company’s operations; compliance with anti-corruption, environmental, health and safety and product registration laws; the Company’s ability to accurately estimate and maintain appropriate levels of recorded liabilities for existing and future contingencies; the Company’s ability to operate within the limitations of its debt covenants; downgrades to the Company’s credit ratings or disruptions to the Company’s ability to access well-functioning capital markets; downturns in certain industries and general economic downturns; conflicts, military actions, terrorist attacks and general instability, particularly in certain energy-producing nations, along with increased security regulations; cost overruns, delays and miscalculations in capacity needs with respect to the Company’s expansion or other capital projects; interruption of, damage to or compromise of the Company’s IT systems and failure to maintain the integrity of customer, colleague or Company data; unfavorable resolution of litigation against us; and the Company’s ability to retain its executive management and other key personnel. These factors are not necessarily all of the important factors that could cause the Company’s actual financial results, performance, achievements or prospects to differ materially from those expressed in or implied by any of its forward-looking statements. Other unknown or unpredictable factors also could harm the Company’s results. All forward-looking statements attributable to the Company or persons acting on the Company’s behalf are expressly qualified in their entirety by the cautionary statements set forth above. Forward-looking statements speak only as of the date they are made, and the Company does not undertake or assume any obligation to update publicly any of these forward-looking statements to reflect actual results, new information or future events, changes in assumptions or changes in other factors affecting forward-looking statements, except to the extent required by applicable laws. If the Company updates one or more forward-looking statements, no inference should be drawn that the Company will make additional updates with respect to those or other forward-looking statements. The “Company,” “we,” “our” or “us” means Stepan Company and one or more of its subsidiaries only.

Overview

The Company produces and sells intermediate chemicals that are used in a wide variety of applications worldwide. The overall business comprises three reportable segments:

• Surfactants – Surfactants, which accounted for 67 percent of Company consolidated net sales for the first three quarters of 2017, are principal ingredients in consumer and industrial cleaning products such as detergents for washing clothes, dishes, carpets, floors and walls, as well as shampoos and body washes. Other applications include fabric softeners, germicidal quaternary compounds, lubricating ingredients, emulsifiers for spreading agricultural products, oilfield chemicals (for drilling, production and formulation stimulation) and industrial applications such as latex systems, plastics and composites. Surfactants are manufactured at four North American sites (United States), three European sites (United Kingdom, France and Germany), four Latin American sites (Mexico, Colombia and two sites in Brazil) and two Asian sites (Philippines and Singapore). In 2016, the Company shut down its production facility in Canada, moving the production of goods previously manufactured in Canada to other Company North American production sites. Manufacturing operations at that facility ceased in the fourth quarter of 2016.

19

Decommissioning activities will continue throughout 2017. In October 2016, the Company’s subsidiary in Brazil acquired the commercial business of Tebras Tensoativos do Brazil Ltda. (Tebras) and the sulfonation production facility of PBC Industria Quimica Ltda (PBC). See the “Acquisition Agreement” section in this “Overview” for a description of 2017 acquisition activity.

• Polymers – Polymers, which accounted for 29 percent of consolidated net sales for the first three quarters of 2017, include polyurethane polyols, polyester resins and phthalic anhydride.  Polyurethane polyols are used in the manufacture of rigid foam for thermal insulation in the construction industry and are also a base raw material for coatings, adhesives, sealants and elastomers (collectively, CASE products). Powdered polyester resins are used in coating applications. CASE and polyester resins are collectively referred to as specialty polyols. Phthalic anhydride is used in unsaturated polyester resins, alkyd resins and plasticizers for applications in construction materials and components of automotive, boating and other consumer products. In addition, the Company uses phthalic anhydride internally in the production of polyols.  In the United States, polyurethane polyols and phthalic anhydride are manufactured at the Company’s Millsdale, Illinois, site and specialty polyols are manufactured at the Company’s Columbus, Georgia, site. In Europe, polyurethane polyols are manufactured by the Company’s subsidiary at its site in Wesseling, Germany, and specialty polyols are manufactured by the Company’s subsidiary at its site in Brzeg Dolny, Poland. In China, polyurethane polyols and specialty polyols are produced at the Company’s Nanjing, China, manufacturing plant.

• Specialty Products – Specialty Products, which accounted for four percent of consolidated net sales for the first three quarters of 2017, include flavors, emulsifiers and solubilizers used in food, flavoring, nutritional supplement and pharmaceutical applications. Specialty Products are primarily manufactured at the Company’s Maywood, New Jersey, site and, in some instances, at outside contractors.

Acquisition Agreement

On June 13, 2017, the Company announced that it had reached an agreement with BASF Mexicana, S.A. DE C.V. (BASF) to acquire BASF’s production facility in Ecatepec, Mexico, and a portion of its related surfactants business. The facility, which is near Mexico City, has over 50,000 metric tons of capacity, 124,000 square feet of warehouse space, a laboratory and office space. The acquisition is currently expected to be completed in the first quarter of 2018, subject to closing conditions.  The acquisition supports the Company’s growth strategy in Latin America. The Company believes that this acquisition should enhance its market position and supply capabilities for surfactants in Mexico and positions the Company to grow in both the consumer and functional surfactants markets.

Deferred Compensation Plans

The accounting for the Company’s deferred compensation plans can cause period-to-period fluctuations in Company expenses and profits. Compensation expense results when the values of Company common stock and mutual fund investment assets held for the plans increase, and compensation income results when the values of Company common stock and mutual fund investment assets decline. The pretax effect of all deferred compensation-related activities for the three and nine months ended September 30, 2017 and 2016 and the income statement line items in which the effects of the activities were recorded are displayed in the following tables:

	Income (Expense)

Effects of Foreign Currency Translation

The Company’s foreign subsidiaries transact business and report financial results in their respective local currencies. As a result, foreign subsidiary income statements are translated into U.S. dollars at average foreign exchange rates appropriate for the reporting period. Because foreign exchange rates fluctuate against the U.S. dollar over time, foreign currency translation affects period-to-period comparisons of financial statement items (i.e., because foreign exchange rates fluctuate, similar period-to-period local currency results for a foreign subsidiary may translate into different U.S. dollar results). The following table presents the effects that foreign currency translation had on the period-over-period changes in consolidated net sales and various income line items for the three and nine months ended September 30, 2017 and 2016:

	Three Months Ended September 30							Increase
(In millions)	2017		2016		Increase (Decrease)			Due to Foreign Currency Translation

RESULTS OF OPERATIONS

Three Months Ended September 30, 2017 and 2016

Summary

Net income attributable to the Company for the third quarter of 2017 increased three percent to $21.9 million, or $0.94 per diluted share, from $21.4 million, or $0.92 per diluted share, for the third quarter of 2016. Adjusted net income declined 16 percent to $21.4 million, or $0.92 per diluted share, from $25.4 million, or $1.10 per diluted share (see the “Reconciliation of Non-GAAP Adjusted Net Income and Diluted Earnings per Share” section of this MD&A for reconciliations between reported net income attributable to the Company and related earnings per diluted share and non-GAAP adjusted net income and related earnings per diluted share). Below is a summary discussion of the major factors leading to the quarter-over-quarter changes in net sales, profits and expenses.  A detailed discussion of segment operating performance for the third quarter of 2017 compared to the third quarter of 2016 follows the summary.

Consolidated net sales increased $42.8 million, or 10 percent, between quarters. The increase was attributable to higher selling prices, the favorable effects of foreign currency translation and a one percent increase in sales volume, which accounted for $34.2 million, $6.1 million and $2.5 million, respectively, of the quarter-over-quarter change in net sales. The higher selling prices reflected the pass through to customers of increased costs for certain raw materials. Surfactant sales volume increased one percent between quarters, while Polymer and Specialty Products sales volumes declined one percent and nine percent, respectively.

Operating income for the third quarter of 2017 improved $1.6 million, or five percent, from operating income for the third quarter of 2016. Consolidated operating income was favorably affected by deferred compensation expense which declined $7.5 million quarter over quarter. With respect to the segments, Surfactant operating income improved but was more than offset by declines in Polymer and Specialty Products results.

Operating expenses (including business restructuring expenses) for the third quarter of 2017 decreased $9.4 million, or 17 percent, from operating expenses for the third quarter of 2016. Deferred compensation accounted for $7.5 million of the decline. Changes in the individual income statement line items that comprise the Company’s operating expenses were as follows:

• Selling expenses declined $0.3 million, or two percent, quarter over quarter. The decrease was primarily attributable to lower U.S. fringe benefits expenses ($1.1 million) partially offset by expenses associated with Tebras and PBC ($0.4 million), which were acquired in October 2016, and the accumulation of smaller increases for a number of other expense items. Reduced incentive-based compensation expenses led to the lower fringe benefits.

• Administrative expenses decreased $0.4 million, or two percent, quarter over quarter due to lower U.S. fringe benefit expenses ($1.2 million) partially offset by increased legal and environmental expenses ($1.0 million). Reduced incentive-based compensation expenses led to the lower fringe benefits

• Research, development and technical service (R&D) expenses declined $1.6 million, or 11 percent, between quarters due to lower U.S. fringe benefit expenses. The reduced fringe benefit expenses reflected lower incentive-based compensation.

• Deferred compensation expense declined $7.5 million quarter over quarter primarily due to a $3.48 per share decrease in the market price of Company common stock in the third quarter of 2017 compared to a $13.13 per share increase for the third quarter of 2016. See the “Overview” and “Corporate Expenses” sections of this MD&A for further details.

• Business restructuring expenses were $0.4 million in the third quarter of 2017 with no such expenses in the third quarter of 2016. The restructuring expense related to the continued asset decommissioning for the Company’s plant in Canada, which ceased operations in the fourth quarter of 2016. See Note 14 to the condensed consolidated financial statements for additional information regarding the Company’s restructuring activities.  

Other, net was $1.8 million of income for the third quarter of 2017 compared to $1.2 million of income for the same period of 2016. The Company reported foreign exchange gains of $0.6 million in the third quarter of 2017 compared to gains of $0.3 million in third quarter of 2016. In addition, investment gains (including realized and unrealized gains and losses) for the Company’s deferred compensation and supplemental defined contribution mutual fund assets totaled $1.2 million in the third quarter of 2017 compared to $0.9 million of income in last year’s third quarter.

The effective tax rate was 25 percent for the third quarter of 2017 compared to 21 percent for the third quarter of 2016.  The increase was attributable to the following items: (1) lower excess tax benefits derived from stock-based compensation awards exercised or distributed in the third quarter of 2017 versus the third quarter of 2016; and (2) a less favorable geographical mix of income in the third quarter of 2017 versus the third quarter of 2016.

Surfactants

Surfactant net sales for the third quarter of 2017 increased $31.0 million, or 11 percent, over net sales for the third quarter of 2016. Higher selling prices, a one percent increase in sales volume and the favorable effects of foreign currency translation accounted for $25.1 million, $3.6 million and $2.3 million, respectively, of the quarter-over-quarter increase in net sales. The increase in selling prices reflected the pass through to customers of higher costs for certain raw materials. The increase in sales volume was principally attributable to sales associated with the Latin American region’s October 2016 acquisitions of Tebras and PBC. A quarter-over-quarter comparison of net sales by region follows:

	For the Three Months Ended
(Dollars in thousands)	September 30, 2017		September 30, 2016		Increase (Decrease)			Percent Change
North America	$	184,889	$	175,333	$	9,556			5
Europe		69,325		61,451		7,874			13
Latin America		51,241		36,078		15,163			42
Asia		15,989		17,605		(1,616	)		-9
Total Surfactants Segment	$	321,444	$	290,467	$	30,977			11

Net sales for North American operations increased five percent between quarters. Higher selling prices and the favorable effect of foreign currency translation positively affected the quarter-over-quarter change in net sales by $11.2 million and $0.3 million, respectively. A one percent decline in sales volume offset the impacts of selling prices and currency translation by $1.9 million. Selling prices increased six percent quarter over quarter mainly due to the pass through of certain increased raw material costs to customers and to a more favorable mix of sales. The one percent decline in sales volume reflected decreased sales of commodity products used in laundry and cleaning and personal care applications largely offset by increased sales of products used in household, industrial and institutional (HI&I), agricultural chemical and oilfield applications. Sales volumes of general surfactants sold to distributors also increased quarter over quarter.

Net sales for European operations increased 13 percent due to a seven percent increase in selling prices, the favorable effects of foreign currency translation and a two percent increase in sales volume, which accounted for $4.6 million, $2.2 million and $1.1 million of the quarter-over-quarter improvement in net sales, respectively. The increase in selling prices primarily resulted from the pass through of higher costs for certain raw materials. The increase in sales volume was largely attributable to higher demand for laundry and cleaning products and agricultural chemicals, partially offset by reduced sales volumes of general surfactants sold to distributors. A quarter-over-quarter strengthening of the European euro relative to the U.S. dollar led to the foreign currency translation effect.

23

Net sales for Latin American operations increased 42 percent due to higher selling prices, a 19 percent increase in sales volume and the favorable effects of foreign currency translation, which accounted for $7.6 million, $6.7 million and $0.9 million, respectively, of the quarter-over-quarter increase in net sales. Selling prices increased 17 percent due to the pass through to customers of higher quarter-over-quarter raw material costs and a more favorable mix of sales. The improved sales volume reflected new business associated with the October 2016 acquisitions of Tebras and PBC, partially offset by lower demand and lost commodity business for products used in laundry and cleaning applications. The foreign currency translation effect primarily resulted from the quarter-over-quarter strengthening of the Brazilian real and Mexican peso relative to the U.S. dollar.

Net sales for Asian operations declined nine percent largely due to a 20 percent decrease in sales volume and the unfavorable effects of foreign currency translation, which negatively affected the quarter-over-quarter change in net sales by $3.5 million and $1.2 million, respectively. Higher average selling prices, primarily resulting from the pass through of certain increased raw material costs to customers, favorably affected the change in net sales by $3.1 million. The sales volume decline was primarily due to weaker demand for commodity laundry and cleaning products. A weaker Philippine peso relative to the U.S. dollar caused the negative foreign currency translation effect.

Surfactant operating income for the third quarter of 2017 increased $1.7 million, or eight percent, over operating income for the third quarter of 2016.  Gross profit for the third quarter of 2017 remained essentially unchanged from gross profit for same quarter of 2016, as improvement in Latin America was offset by a decline in Asia. Operating expenses decreased $1.7 million, or seven percent. Quarter-over-quarter comparisons of gross profit by region and total segment operating expenses and operating income follow:

(a) In 2017, the Company changed its internal financial statement classification for certain transportation costs, transferring such costs from operating expenses to cost of sales. In this segment discussion, the 2016 North America gross profit and total operating expenses have been changed from the amounts presented in 2016 to make such amounts consistent with the current year classification. Surfactants segment operating income remained unchanged.

Gross profit for North American operations increased less than one percent primarily due to lower manufacturing overhead costs resulting from the closure of the Company’s Canada manufacturing operations in the fourth quarter of 2016.

Gross profit for European operations declined two percent between quarters largely due to the impact of increased raw material costs that more than offset the effects of the two percent increase in sales volume and lower quarter-over-quarter manufacturing costs. Prior year manufacturing costs included approximately $0.7 million of expense related to a mandatory 30-day inspection shutdown of the Germany manufacturing plant.

Gross profit for Latin American operations increased $2.4 million, or 46 percent, due to the 19 percent improvement in sales volume, a more profitable mix of sales and a $0.2 million favorable effect of foreign currency translation.

Gross profit for Asia declined $2.4 million, or 38 percent, quarter over quarter primarily due to the 20 percent decrease in sales volume. Gross profit was also negatively affected by higher unit manufacturing costs caused by the lower utilization of the Singapore plant.

Operating expenses for the Surfactant segment declined $1.7 million, or seven percent, quarter over quarter principally due to lower R&D expenses. A decline in U.S. incentive-based compensation was the major contributor to the decreased R&D expenses.

Polymers

Polymer net sales for the third quarter of 2017 increased $13.6 million, or 10 percent, over net sales for the third quarter of 2016.  Higher selling prices, resulting from the pass through of increased costs for certain raw materials, and the positive effects of foreign currency translation favorably affected the quarter-over-quarter net sales change by $11.5 million and $3.6 million, respectively. Sales

volume declined one percent, which negatively impacted the change in net sales by $1.5 million. North American operationsaccounted for the sales volume decline. A quarter-over-quarter comparison of net sales by region follows:

	For the Three Months Ended
(Dollars in thousands)	September 30, 2017		September 30, 2016		Increase		Percent Change
North America	$	86,002	$	85,534	$	468		1
Europe		53,008		41,453		11,555		28

Total Polymers Segment	$	147,754	$	134,144	$	13,610		10

Net sales for North American operations increased one percent due to higher selling prices, partially offset by lower sales volume. Selling prices increased four percent, which had a $3.7 million positive effect on the quarter-over-quarter change in net sales. The pass through of certain higher quarter-over-quarter raw material costs to customers led to the increased selling prices. Sales volume declined four percent, which unfavorably impacted the net sales change by $3.2 million. Sales volume of polyols used in rigid foam applications declined seven percent mainly due to lost share from a major customer. Phthalic anhydride sales volume declined two percent. Sales volume of specialty polyols increased seven percent due to greater demand for product used in powdered resins and CASE applications.

Net sales for European operations increased 28 percent due to higher selling prices, the favorable effects of foreign currency translation and a two percent increase in sales volume, which accounted for $7.3 million, $3.6 million and $0.7 million, respectively, of the quarter-over-quarter net sales increase. Selling prices increased 17 percent primarily due to the pass through to customers of cost increases for certain raw materials. The sales improvement was primarily attributable to increased sales volume of specialty polyols, which reflected the Company’s successful efforts to utilize the capacity of its new reactor in Poland.

Net sales for Asia and Other operations increased 22 percent quarter over quarter due to higher selling prices and a seven percent improvement in sales volume. Sales volumes related to China operations increased 11 percent.

Polymer operating income for the third quarter of 2017 declined $6.0 million, or 22 percent, from operating income for the same period of last year. Gross profit decreased $6.2 million, or 18 percent, primarily due to higher material costs and lower sales volume, particularly for North American operations. European operations reported significant gross profit improvement due principally to lower manufacturing costs. Operating expenses declined $0.2 million, or three percent, between quarters. Quarter-over-quarter comparisons of gross profit by region and total segment operating expenses and operating income follow:

	For the Three Months Ended
(Dollars in thousands)	September 30, 2017		September 30, 2016 (a)		Increase (Decrease)			Percent Change

(a) In 2017, the Company changed its internal financial statement classification for certain transportation costs, transferring such costs from operating expenses to cost of sales. In this segment discussion, the 2016 North America gross profit and total operating expenses have been changed from the amounts presented in 2016 to make such amounts consistent with the current year classification. Polymers segment operating income remained unchanged.

Gross profit for North American operations declined 33 percent quarter over quarter primarily due to reduced margins and the four percent decline in sales volume. The decline in margins reflected the effect of higher raw material costs that, due to competitive reasons, could not entirely be passed on to customers. Unit overhead costs were also higher between quarters due to phthalic anhydride equipment issues that caused periodic outages and slowdowns of manufacturing operations.

Gross profit for European operations increased 74 percent quarter over quarter. Increased margins, due to lower unit manufacturing costs, and increased sales volume led to the gross profit improvement. Last year’s third quarter gross profit was negatively impacted by a mandatory 30-day inspection shutdown of the Company’s plant in Germany, which resulted in additional plant expenses (approximately $1.5 million greater than in the third quarter of 2017) and limited production. The favorable effects of foreign currency translation contributed $0.6 million to the increased gross profit.

25

Gross profit for Asia and Other operations declined 68 percent due to higher overhead costs resulting from lower production at the Company’s plant in Nanjing, China, and to higher raw material costs. In 2016, the Nanjing plant supplied product to other Company locations as a result of the mandatory inspection shutdown at the Germany plant.

Operating expenses for the Polymers segment declined $0.2 million, or three percent, quarter over quarter.

Specialty Products

Net sales for the third quarter of 2017 declined $1.8 million, or nine percent, from net sales for the third quarter of 2016. A less favorable mix of sales resulting from the timing of orders for certain products used in flavor and pharmaceutical applications and a nine percent decline in sales volume led to the lower net sales. Operating income declined $1.3 million quarter over quarter due to the less favorable mix of sales partially offset by improved margins for food ingredient and nutritional supplement products.

Corporate Expenses

Corporate expenses, which are comprised of deferred compensation and other operating expenses that are not allocated to the reportable segments, declined $7.1 million between quarters to $14.3 million for the third quarter of 2017 from $21.4 million for the third quarter of 2016. The decline in corporate expense was primarily attributable to a $7.5 million favorable change in deferred compensation expense. Deferred compensation was $0.1 million of income for the third quarter of 2017 compared to $7.4 million of expense for the same quarter of last year. In addition to deferred compensation, fringe benefits declined between quarters by $1.2 million, largely due to a decline in expense for incentive-based compensation. The foregoing items were partially offset by increased legal and environmental expenses ($1.0 million) and the previously discussed restructuring expenses ($0.4 million).

The $7.5 million favorable change in deferred compensation expense reflected a $3.48 per share decrease in the market price of Company common stock in the third quarter of 2017 compared to a $13.13 per share increase for the third quarter of 2016. The following table presents the quarter-end Company common stock market prices used in the computation of deferred compensation expenses for the three months ended September 30, 2017 and 2016:

Nine Months Ended September 30, 2017 and 2016

Summary

Net income attributable to the Company for the first three quarters of 2017 increased five percent to $81.7 million, or $3.50 per diluted share, from $77.8 million, or $3.38 per diluted share, for the first three quarters of 2016. Adjusted net income declined two percent to $84.0 million, or $3.60 per diluted share, from $85.9 million, or $3.73 per diluted share (see the “Reconciliation of Non-GAAP Adjusted Net Income and Diluted Earnings per Share” section of this MD&A for reconciliations between reported net income attributable to the Company and related earnings per diluted share and non-GAAP adjusted net income and related earnings per diluted share). Below is a summary discussion of the major factors leading to the year-over-year changes in net sales, profits and expenses.  A detailed discussion of segment operating performance for the first nine months of 2017 compared to the first nine months of 2016 follows the summary.

Consolidated net sales increased $105.7 million, or eight percent, between years, primarily due to higher selling prices that were precipitated by the pass through to customers of increased costs for certain raw materials. The increased selling prices favorably affected the year-over-year change in net sales by $140.1 million. Sales volume declined two percent, which had a $31.9 million unfavorable effect on the change in net sales. Sales volume declined three percent and four percent for the Surfactant and Specialty Products segments, respectively, and was essentially flat between years for the Polymer segment. Foreign currency translation negatively impacted the net sales change by $2.5 million.  

Operating income for the first three quarters of 2017 declined $0.9 million, or one percent, from operating income reported for the first three quarters of 2016. Surfactant and Specialty Product operating incomes improved year over year but were more than offset by a decline in Polymer results. Polymer operating income was negatively impacted by higher raw material costs that could not entirely be recouped through selling price increases.

26

Operating expenses (including business restructuring expenses) declined $11.2 million, or seven percent, between years. Lower deferred compensation expense accounted for $7.3 million of the operating expense decrease. Changes in the individual income statement line items that comprise the Company’s operating expenses were as follows:

• Selling expenses declined $1.8 million, or four percent, year over year largely due to lower U.S. fringe benefit expenses ($1.5 million). The decrease in fringe benefit expenses resulted from reduced expense for incentive-based compensation.

• Administrative expenses declined $1.0 million, or two percent, year over year. Lower U.S. expenses for fringe benefits ($1.5 million) and relocation ($0.7 million), partially offset by increased expenses for consulting ($1.6 million), led to the decrease in administrative expenses. The decline in fringe benefit expense reflected lower expense for incentive-based compensation. The increase in consulting fees was primarily attributable to external resources engaged in 2017 to support various corporate projects.

• R&D expenses declined $1.9 million, or four percent, year over year due to a decrease in U.S. fringe benefits expense, which was driven by lower expenses for incentive-based compensation.

• Deferred compensation expense declined $7.3 million, or 58 percent, year over year due to a smaller year-over-year increase in the market price of Company common stock, partially offset by larger year-over-year increases in the market values of the mutual funds held for the deferred compensation plan. See the “Overview” and “Corporate Expenses” sections of this MD&A for further details.

• Business restructuring expenses were $1.8 million for the first three quarters of 2017 compared to $1.1 million for the first three quarters of 2016. Approximately $1.7 million of the restructuring expense related to the continued asset decommissioning for the Company’s plant in Canada, which ceased operations in the fourth quarter of 2016. The remaining $0.1 million of restructuring expense related to a second quarter 2017 workforce reduction at the Company’s Singapore plant. The $1.1 million of 2016 restructuring expense was for termination pay expense associated with the Canadian plant closure. See Note 14 to the condensed consolidated financial statements for additional information regarding the Company’s restructuring activities.

Net interest expense for the first three quarters of 2017 declined $1.2 million, or 13 percent, from net interest expense for the first three quarters of 2016 primarily due to lower average debt levels and higher interest income earned on excess cash.

Other, net was $4.0 million of income for the first three quarters of 2017 compared to $0.4 million of income for the same period of last year. The Company posted $3.9 million of investment gains (including realized and unrealized gains and losses) for the Company’s deferred compensation and supplemental defined contribution mutual fund assets in the first three quarters of 2017 compared to $0.9 million of income in the first three quarters of 2016. In addition, the Company reported foreign exchange gains of $0.1 million in the first three quarters of 2017 compared to exchange losses of $0.5 million for the same period a year ago.

The effective tax rate was 26 percent for the first three quarters of 2017 compared to 27 percent for the first three quarters of 2016.  The decrease was attributable to the following items: (1) higher excess tax benefits derived from stock-based compensation awards exercised or distributed in the first three quarters of 2017 versus the first three quarters of 2016; and (2) an unfavorable tax settlement related to a foreign income tax audit recorded in the first quarter of 2016 that did not recur in 2017.

 Surfactants

Surfactant net sales for the first three quarters of 2017 increased $74.4 million, or eight percent, over net sales for the first three quarters of 2016. Higher selling prices, resulting primarily from the pass through of higher costs on certain raw materials to customers, had a favorable $106.3 million effect on the year-over-year change in net sales. A three percent decline in sales volume and the unfavorable effects of foreign currency translation offset the impact of increased selling prices by $26.6 million and $5.3 million, respectively. The Latin America region reported improved sales volume due to sales associated with the October 2016 acquisitions of Tebras and PBC, while sales volumes for the other regions declined. A year-over-year comparison of net sales by region follows:

	For the Nine Months Ended
(Dollars in thousands)	September 30, 2017		September 30, 2016		Increase (Decrease)			Percent Change

Net sales for North American operations increased five percent year over year. Higher selling prices favorably impacted the change in net sales by $50.7 million. Sales volume declined five percent, which offset the effect of increased selling prices by $25.2 million. Average selling prices increased 10 percent between years, reflecting the pass through of certain higher raw material costs to customers and a more favorable mix of sales. The five percent decline in sales volume was largely attributable to decreases in sales volumes for commodity products used in laundry and cleaning and personal care applications. The lower commodity product volumes were partially offset by increased sales for products used in HI&I, agricultural chemicals and oilfield applications. The favorable effect of foreign currency translation added $0.3 million to the year-over-year change in net sales.

Net sales for European operations increased nine percent due to a 16 percent increase in selling prices, partially offset by the unfavorable effects of foreign currency translation and a three percent decline in sales volume. The higher selling prices, which resulted from the pass through to customers of certain increased raw material costs, favorably impacted the year-over-year change in net sales by $28.0 million, while foreign currency translation and lower sales volume unfavorably affected the net sales change by $6.8 million and $5.6 million, respectively. A stronger U.S. dollar relative to the British pound sterling led to the foreign currency translation effect. The three percent decrease in sales volume primarily resulted from declines in commodity personal care sales volume and general surfactants sold to distributors.

28

Net sales for Latin American operations increased 30 percent due to increased selling prices, a nine percent improvement in sales volume and the favorable effects of foreign currency translation, which accounted for $19.4 million, $9.5 million and $4.5 million, respectively, of the year-over-year increase in net sales. The higher selling prices reflected the pass through to customers of increased raw material costs and a more favorable mix of sales.The improved sales volume reflected new business associated with the October 2016 acquisitions of Tebras and PBC and increased sales volume for agricultural chemical products, partially offset by lower demand and lost business for commodity products used in laundry and cleaning applications. The foreign currency translation effect reflected the year-over-year strengthening of the Brazilian real and Colombian peso relative to the U.S. dollar, partially offset by a weaker Mexican peso.

Net sales for Asian operations declined one percent due to a 17 percent decline in sales volume and the unfavorable effects of foreign currency translation, which negatively impacted the year-over-year change in net sales by $8.7 million and $3.2 million, respectively. Lower volumes of commodity laundry and cleaning products sold from the Philippine location and overall lower volumes sold from the Singapore location led to the sales volume decline for Asian operations. A weaker Philippine peso relative to the U.S. dollar caused the negative foreign currency translation effect. Higher selling prices, which reflected the pass through to customers of certain increased raw material costs, offset the effects of sales volume and currency translation by $11.4 million.

Surfactant operating income for the first three quarters of 2017 increased $6.5 million, or eight percent, over operating income for the first three quarters of 2016.  Gross profit increased $3.4 million, or two percent, primarily due to improved results for North American and Latin American operations. Operating expenses decreased $3.2 million, or four percent. Year-over-year comparisons of gross profit by region and total segment operating expenses and operating income follow:

(a) In 2017, the Company changed its internal financial statement classification for certain transportation costs, transferring such costs from operating expenses to cost of sales. In this segment discussion, the 2016 North America gross profit and total operating expenses have been changed from the amounts presented in 2016 to make such amounts consistent with the current year classification. Surfactants segment operating income remained unchanged.

 Gross profit for North American operations increased six percent between years. The effect of improved margins more than offset the impact of the five percent sales volume decline. The margin improvement reflected a more profitable mix of sales and reduced manufacturing overhead costs resulting primarily from the closure of the Company’s Canada manufacturing operations in the fourth quarter of 2016.

Gross profit for European operations declined 15 percent year over year primarily due to reduced sales margins, the three percent sales volume decline and a $0.5 million unfavorable foreign currency translation impact. The lower sales margins reflected the effect of increased raw material costs that could not be entirely passed on to customers through selling price increases. The year-over-year change in gross profit benefitted from 2016 charges for customer claims that did not recur in 2017.

Gross profit for Latin American operations increased 21 percent primarily due to the contributions from the October 2016 acquisitions of Tebras and PBC and to a more profitable mix of sales. A $0.9 million favorable effect of foreign currency translation also contributed to gross profit improvement.

Asia gross profit declined 25 percent largely due to the 17 percent decline in sales volume and to a year-over-year decline in production volume in Singapore, which led to higher unit overhead costs. A $0.6 million unfavorable foreign currency translation effect also contributed to the decline in gross profit. The Company’s plan to lower inventory levels in the region led to the decrease in Singapore production.

Operating expenses for the Surfactant segment declined $3.2 million, or four percent, year over year. R&D and selling expenses declined $2.6 million and $0.5 million, respectively, due primarily to lower overall expenses in the U.S. partially offset by increased

29

expenses related to Tebras and PBC, which were acquired in October 2016.A decline in incentive-based compensation was a factor for the lower U.S. expenses.

Polymers

Polymer net sales for the first three quarters of 2017 increased $33.0 million, or nine percent, over net sales for the same period of 2016. Higher selling prices and the effects of foreign currency translation positively impacted the net sales change by $31.7 million and $2.8 million, respectively. The selling price increases reflected the pass through to customers of certain increased raw material costs. Polymer sales volume declined less than one percent between years, which resulted in a negative $1.5 million impact on the net sales change. A year-over-year comparison of net sales by region follows:

	For the Nine Months Ended
(Dollars in thousands)	September 30, 2017		September 30, 2016		Increase		Percent Change
North America	$	251,291	$	245,292	$	5,999		2
Europe		142,265		118,706		23,559		20

Total Polymers Segment	$	415,551	$	382,540	$	33,011		9

Net sales for North American operations increased two percent due to higher selling prices, which favorably affected the year-over-year net sales change by $12.2 million. Selling prices increased five percent, largely as a result of the pass through of higher raw material costs. Sales volume declined three percent between years, which unfavorably affected the net sales change by $6.2 million. Sales volume of polyols used in rigid foam applications declined two percent mainly due to lost business at a major customer. Phthalic anhydride sales volume declined eight percent due to lower volumes provided to phthalic anhydride co-producers in 2017 than in 2016 and to less demand from a major customer. Specialty polyols sales volume improved five percent on increased volumes for product used in CASE applications.

Net sales for European operations increased 20 percent due to higher selling prices, the favorable effects of foreign currency translation and a two percent increase in sales volume, which accounted for $17.9 million, $3.0 million and $2.7 million, respectively, of the year-over-year net sales increase. Selling prices increased 15 percent primarily due to the pass through of certain raw material cost increases to customers. Specialty polyols used in CASE applications accounted for most of the sales volume increase, as sales volume for polyols used in rigid foam insulation and insulated metal panels was essentially flat year-over-year. The increase in CASE sales volumes reflected the Company’s successful efforts to utilize the capacity of its new reactor in Poland.

Net sales for Asia and Other operations increased 19 percent between years due to higher selling prices and a five percent increase in sales volume, which accounted for $2.6 million and $1.0 million, respectively, of the year-over-year net sales change. Increased raw material costs drove the selling price increase. Most of the sales volume increase reflected new business for the Company’s manufacturing facility in Nanjing, China, that commenced operations in early 2016. Foreign currency translation had a $0.2 million negative effect on the year-over-year change in net sales.

Polymer operating income for the first three quarters of 2017 declined $16.5 million, or 21 percent, from operating income for the first three quarters of 2016. Gross profit decreased $16.6 million, or 16 percent, due to lower margins primarily caused by higher material costs. Operating expenses decreased $0.1 million, or one percent between years. Year-over-year comparisons of gross profit by region and total segment operating expenses and operating income follow:

Polymers segment operating income remained unchanged.

30

Gross profit for North American operations declined 21 percent year over year primarily as a result of reduced margins and the three percent decline in sales volume. The margin decline reflected the effects of higher raw material costs that could not be completely passed on to customers due to competitive pressures. In addition, unit overhead costs were higher between years due to phthalic anhydride equipment issues that caused periodic outages and slowdowns of manufacturing operations in the third quarter of 2017.

Gross profit for European operations increased 11 percent due to the two percent sales volume increase and to lower manufacturing expenses that more than offset the impact of higher raw material costs. In addition, foreign currency translation had a $0.4 million positive effect on Europe’s gross profit. With respect to the reduced manufacturing expenses, 2016 third quarter gross profit was negatively impacted by a mandatory 30-day inspection shutdown of the Germany plant, which resulted in additional plant expenses (approximately $1.5 million greater than in the third quarter of 2017) and limited production.

Gross profit for Asia and Other operations declined $2.3 million due to higher overhead costs resulting from lower utilization of the plant in Nanjing, China, as the 2016 gross profit benefited from production of polyol to build up inventory to support the Company’s Germany plant in advance of its mandatory third quarter 2016 inspection shutdown. Higher raw material costs also negatively impacted year-over-year gross profit.

Specialty Products

Net sales for the first three quarters of 2017 declined $1.7 million, or three percent, from net sales for the first three quarters of 2016. Sales volume declined four percent due to lower sales volumes of products used in food ingredient and nutritional supplement applications. Operating income increased $1.3 million, or 19 percent, due to a more favorable mix of sales resulting from the timing of orders for certain products used in flavoring applications, to improved margins for food ingredient and nutritional supplement products and to lower operating expenses of $0.5 million.

Corporate Expenses

Corporate expenses declined $7.8 million to $47.9 million for the first three quarters of 2017 from $55.7 million for the first three quarters of 2016. The decline was primarily attributable to lower expenses for deferred compensation ($7.3 million), fringe benefits ($1.5 million) and relocation ($0.7 million), partially offset by increased expenses for consulting and environmental ($1.6 million) and the previously discussed business restructuring ($0.7 million). Lower year-over-year incentive-based compensation expenses led the lower fringe benefits. The increase in consulting and environmental expenses reflected external resources engaged in 2017 to support various corporate projects.

Deferred compensation expense declined $7.3 million between years. The result reflected a smaller year-over-year increase in the market price of Company common stock ($2.18 per share increase for the first three quarters of 2017 compared to $22.97 per share increase for the first three quarters of 2016), partially offset by larger year-over-year increases in the market values of the mutual funds held for the deferred compensation plan. The following table presents the period-end Company common stock market prices used in the computation of deferred compensation expenses for the nine months ended September 30, 2017 and 2016:

	2017		2016				2015
	September 30		December 31		September 30		December 31

LIQUIDITY AND CAPITAL RESOURCES

Overview

For the nine months ended September 30, 2017, operating activities were a cash source of $124.7 million versus a source of $119.5 million for the comparable period in 2016. For the current year, investing activities were a use of $63.0 million, as compared to a use of $72.5 million in the prior year period, and financing activities were a use of $29.9 million, as compared to a use of $17.3 million in the prior year period. Cash and cash equivalents increased by $38.4 million compared to December 31, 2016, including a favorable exchange rate impact of $6.6 million.

As of September 30, 2017, the Company’s cash and cash equivalents totaled $264.1 million, including $15.1 million in a U.S. money market fund, which was rated AAA by Standard and Poor’s. Cash in U.S. demand deposit accounts totaled $115.6 million and cash of the Company’s non-U.S. subsidiaries held outside the U.S. totaled $133.4 million as of September 30, 2017.

Operating Activity

Net income increased by $3.9 million versus the comparable period in 2016. Working capital was a cash use of $30.0 million versus a use of $37.9 million for the comparable year-ago period.

31

Year-to-date accounts receivable were a use of $37.7 million compared to a use of $30.2 million for the comparable period in 2016. Inventories were a source of $14.8 million in 2017 versus a use of $12.5 million in 2016. Accounts payable and accrued liabilities were a use of $6.5 million in 2017 compared to a source of $5.1 million for the same period in 2016.

Working capital requirements were higher year-to-date, compared to the same period in 2016 primarily due to the above noted change in accounts payable and accrued liabilities. The year-to-date accounts receivables increase was primarily due to selling price increases. The year-to-date inventory decrease was mainly due to lower quantities. It is management’s opinion that the Company’s liquidity is sufficient to provide for potential increases in working capital during 2017.

Investing Activity

Cash outflows from investing activities were down by $9.5 million year-over-year. Cash outflows from investing activities year-to-date included capital expenditures of $57.9 million compared to $69.8 million for the comparable period last year. Other investing activities consumed $5.1 million in 2017 versus a use of $2.8 million in 2016. The increase in other investing activities was primarily attributable to the $4.3 million purchase price working capital adjustment payment made in the first quarter of 2017 related to the 2016 fourth quarter acquisitions of Tebras and PBC.  

For 2017, the Company estimates that total capital expenditures will range from $85 million to $95 million including capacity expansions in the United States, Brazil and Germany.

Financing Activity

Cash flow used for financing activities was a use of $29.9 million in 2017 versus a use of $17.3 million in 2016. The Company purchases its common stock in the open market from time to time to fund its own benefit plans and also to mitigate the dilutive effect of new shares issued under its benefit plans. The Company may, from time to time, seek to retire or purchase additional amounts of its outstanding equity and/or debt securities through cash purchases and/or exchanges for other securities, in open market purchases, privately negotiated transactions or otherwise, including pursuant to a Rule 10b5-1 plan. Such repurchases or exchanges, if any, will depend on prevailing market conditions, the Company’s liquidity requirements, contractual restrictions and other factors. The amounts involved may be material. For the nine months ended September 30, 2017, the Company purchased 57,963 shares in the open market at a total cost of $4.5 million.  At September 30, 2017, there were 659,966 shares remaining under the current share repurchase authorization.

Debt and Credit Facilities

Consolidated balance sheet debt decreased by $12.6 million for the current year, from $317.0 million to $304.4 million due to a decrease of both domestic and foreign debt. Since December 31, 2016, net debt (which is defined as total debt minus cash – see the “Reconciliation of Non-GAAP Net Debt” section of this MD&A) decreased by $51.0 million, from $91.3 million to $40.3 million.

As of September 30, 2017, the ratio of total debt to total debt plus shareholders’ equity was 29.3 percent compared to 33.3 percent at December 31, 2016. As of September 30, 2017, the ratio of net debt to net debt plus shareholders’ equity was 5.2 percent, compared to 12.6 percent at December 31, 2016. At September 30, 2017, the Company’s debt included $305.0 million of unsecured private placement loans with maturities ranging from 2017 through 2027. These loans are the Company’s primary source of long-term debt financing and are supplemented by bank credit facilities to meet short and medium-term needs.

The Company has a committed $125.0 million multi-currency syndicated revolving credit agreement. The credit agreement allows the Company to make unsecured borrowings, as requested from time to time, for working capital and other corporate purposes. This unsecured facility is the Company’s primary source of short-term borrowings and is committed through July 10, 2019, with terms and conditions that are substantially equivalent to those of the Company’s other U.S. loan agreements. As of September 30, 2017, the Company had outstanding letters of credit of $4.7 million under the revolving credit agreement, and no borrowings, with $120.3 million remaining available. The Company anticipates that cash from operations, committed credit facilities and cash on hand will be sufficient to fund anticipated capital expenditures, working capital, dividends and other planned financial commitments for the foreseeable future.

Certain foreign subsidiaries of the Company maintain term loans and short-term bank lines of credit in their respective local currencies to meet working capital requirements as well as to fund capital expenditure programs and acquisitions. At September 30, 2017, the Company’s foreign subsidiaries had outstanding debt of $0.5 million.

The Company has material debt agreements that require the maintenance of minimum interest coverage and minimum net worth. These agreements also limit the incurrence of additional debt as well as the payment of dividends and repurchase of treasury shares. Testing for these agreements is based on the combined financial statements of the U.S. operations of the Company, Stepan Canada Inc., Stepan Quimica Ltda., Stepan Specialty Products, LLC, Stepan Specialty Products B.V. and Stepan Asia Pte. Ltd. (the Restricted Group). Under the most restrictive of these debt covenants:

32

1. The Restricted Group must maintain a minimum interest coverage ratio, as defined within the agreements, of 1.75 to 1.00, for the preceding four calendar quarters.

2. The Restricted Group must maintain net worth of at least $325.0 million.

3. The Restricted Group must maintain a ratio of long-term debt to total capitalization, as defined in the agreements, not to exceed 60 percent.

4. The Restricted Group may pay dividends and purchase treasury shares after December 31, 2013, in amounts of up to $100.0 million plus 100 percent of net income and cash proceeds of stock option exercises, measured cumulatively after June 30, 2014. The maximum amount of dividends that could have been paid within this limitation is disclosed as unrestricted retained earnings in Note 12 to the condensed consolidated financial statements.

The Company believes it was in compliance with all of its loan agreements as of September 30, 2017. Based on current projections, the Company believes it will be in compliance with its loan agreements throughout 2017.

ENVIRONMENTAL AND LEGAL MATTERS

The Company’s operations are subject to extensive federal, state and local environmental laws and regulations and similar laws in the other countries in which the Company does business. Although the Company's environmental policies and practices are designed to address compliance with these laws and regulations, these policies and practices may not be effective, or future developments and increasingly stringent environmental regulation could require the Company to make additional unforeseen environmental expenditures.  The Company expects to continue to invest in the equipment and facilities necessary to comply with existing and future regulations.  For the nine months ended September 30, 2017 and 2016, the Company’s expenditures for capital projects related to the environment were $1.8 million and $0.9 million, respectively.  These projects are capitalized and depreciated over their estimated useful lives, which are typically 10 years.  Recurring costs associated with the operation and maintenance of facilities for waste treatment and disposal and managing environmental compliance in ongoing operations at the Company’s manufacturing locations were $20.3 million and $18.2 million for the nine months ended September 30, 2017 and 2016, respectively.  

Over the years, the Company has received requests for information related to or has been named by the government as a potentially responsible party at a number of waste disposal sites where cleanup costs have been or may be incurred under CERCLA and similar state statutes.  In addition, damages are being claimed against the Company in general liability actions for alleged personal injury or property damage in the case of some disposal and plant sites.  The Company believes that it has made adequate provisions for the costs it may incur with respect to the sites.  It is the Company’s accounting policy to record liabilities 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 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.  After partial remediation payments at certain sites, the Company has estimated a range of possible environmental and legal losses of $25.0 million to $46.1 million at September 30, 2017 compared to $25.7 million to $46.5 million at December 31, 2016.  At September 30, 2017, and December 31, 2016, the Company's accrued liability for such losses, which represented the Company’s best estimate within the estimated range of possible environmental and legal losses, was $25.0 million and $25.8 million, respectively.  During the nine-month period ended September 30, 2017, cash outlays related to legal and environmental matters approximated $1.4million compared to $1.0 million for the same period in 2016.

For certain sites, the Company has responded to information requests made by federal, state or local government agencies but has received no response confirming or denying the Company’s stated positions. As such, estimates of the total costs, or range of possible costs, of remediation, if any, or the Company’s share of such costs, if any, cannot be determined with respect to these sites. Consequently, the Company is unable to predict the effect thereof on the Company’s financial position, cash flows and results of operations. Based upon the Company’s present knowledge with respect to its involvement at these sites, the possibility of other viable entities’ responsibilities for cleanup, and the extended period over which any costs would be incurred, the Company believes that these matters, individually and in the aggregate, will not have a material effect on the Company’s financial position. However, in the event of one or more adverse determinations with respect to such sites in any annual or interim period, the effect on the Company’s cash flows and results of operations for those periods could be material. Certain of these matters are discussed in Item 1, Part 2, Legal Proceedings, in this report and in other filings of the Company with the SEC, which are available upon request from the Company.  See also Note 7 to the condensed consolidated financial statements for a summary of the environmental proceedings related to certain environmental sites.

OUTLOOK

Reported net income for the first nine months of 2017 was up five percent, while adjusted net income was slightly below the record first nine months of 2016.  The fourth quarter of 2016 was negatively impacted by expenses that are not expected to recur in the fourth quarter of 2017.  In addition, the Company believes its diversification efforts and enhanced internal efficiencies should positively impact the fourth quarter of 2017. Although increased competitive activity in North America will persist, the Company has begun to recover higher raw material costs within its Polymer segment and continues to benefit from growing global market volumes for insulation materials.  Management remains optimistic that the Company will deliver full year adjusted earnings growth.

There have been no changes to the critical accounting policies disclosed in the Company’s 2016 Annual Report on Form 10-K.

The Company believes that certain non-GAAP measures, when presented in conjunction with comparable GAAP measures, are useful for evaluating the Company’s operating performance and provide better clarity on the impact of non-operational items. Internally, the Company uses this non-GAAP information as an indicator of business performance and evaluates management’s effectiveness with specific reference to this indicator.  These measures should be considered in addition to, not a substitute for or superior to, measures of financial performance prepared in accordance with GAAP. The cumulative tax effect was calculated using the statutory tax rates for the jurisdictions in which the noted transactions occurred.

RECONCILIATION OF NON-GAAP NET DEBT

(In millions)	September 30, 2017			December 31, 2016
Current Maturities of Long-Term Debt as Reported	$	21.1		$	28.1

Less Cash and Cash Equivalents as Reported		(264.1	)		(225.7	)
Net Debt	$	40.3		$	91.3

Management uses the non-GAAP net debt metric to gain a more complete picture of the Company’s overall liquidity, financial flexibility and leverage level. This adjusted measure should be considered supplemental to and not a substitute for financial information prepared in accordance with GAAP. The Company's definition of this adjusted measure may differ from similarly titled measures used by other entities.

Fair Value Measurements

3. FAIR VALUE MEASUREMENTS

The following describe the financial instruments held by the Company at September 30, 2017, and December 31, 2016, and the methods and assumptions used to estimate the instruments’ fair values:

Cash and cash equivalents

Carrying value approximated fair value because of the short maturity of the instruments.

Derivative assets and liabilities

Derivative assets and liabilities included the foreign currency exchange contracts are discussed in Note 4.  Fair value and carrying value were the same because the contracts were recorded at fair value.  The fair values of the foreign currency contracts were calculated as the difference between the applicable forward foreign exchange rates at the reporting date and the contracted foreign exchange rates multiplied by the contracted notional amounts.  See the table that follows the financial instrument descriptions for the reported fair values of derivative assets and liabilities.

Long-term investments

Long-term investments included the mutual fund assets the Company held to fund a portion of its deferred compensation liabilities and all of its non-qualified supplemental executive defined contribution obligations. Fair value and carrying value were the same because the mutual fund assets were recorded at fair value. Fair values for the mutual funds were calculated using the published market price per unit at the reporting date multiplied by the number of units held at the reporting date.  See the table that follows the financial instrument descriptions for the reported fair value of long-term investments.

Debt obligations

The fair value of debt with original maturities greater than one year comprised the combined present values of scheduled principal and interest payments for each of the various loans, individually discounted at rates equivalent to those which could be obtained by the Company for new debt issues with durations equal to the average life to maturity of each loan.  The fair values of the remaining Company debt obligations approximated their carrying values due to the short-term nature of the debt.  The Company’s fair value measurements for debt fall in level 2 of the fair value hierarchy.

At September 30, 2017, and December 31, 2016, the fair values of debt and the related carrying values, including current maturities, were as follows (the fair value and carrying value amounts are presented without regard to unamortized debt issuance costs of $1,025,000  and $1,141,000 as of September 30, 2017 and December 31, 2016, respectively):

The following tables present financial assets and liabilities measured on a recurring basis at fair value as of September 30, 2017, and December 31, 2016, and the level within the fair value hierarchy in which the fair value measurements fall:

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivative Instruments

4. DERIVATIVE INSTRUMENTS

The Company is exposed to certain risks relating to its ongoing business operations. The primary risk managed by the use of derivative instruments is foreign currency exchange risk.  The Company holds forward foreign currency exchange contracts that are not designated as any type of accounting hedge as defined by GAAP.  The Company uses these contracts to manage its exposure to exchange rate fluctuations on certain Company subsidiary cash, accounts receivable, accounts payable and other obligation balances that are denominated in currencies other than the entities’ functional currencies. The forward foreign exchange contracts are recognized on the balance sheet as either an asset or a liability measured at fair value. Gains and losses arising from recording the foreign exchange contracts at fair value are reported in earnings as offsets to the losses and gains reported in earnings arising from the re-measurement of the asset and liability balances into the applicable functional currencies. At September 30, 2017, and December 31, 2016, the Company had open forward foreign currency exchange contracts, all with durations of approximately one to three months, to buy or sell foreign currencies with U.S. dollar equivalent amounts of $39,220,000 and $33,372,000, respectively.

The fair values of the derivative instruments held by the Company on September 30, 2017, and December 31, 2016, are disclosed in Note 3. Derivative instrument gains and losses for the three- and nine-month periods ended September 30, 2017 and 2016, were immaterial.  For amounts reclassified out of accumulated other comprehensive income (loss) (AOCI) into earnings for the three- and nine-month periods ended September 30, 2017 and 2016, see Note 10.

Stock-Based Compensation

5. STOCK-BASED COMPENSATION

On September 30, 2017, the Company had stock options outstanding under its 2006 Incentive Compensation Plan and stock options, stock awards and SARs outstanding under its 2011 Incentive Compensation Plan.  SARs granted prior to 2015 are cash-settled, and SARs granted in 2015 and thereafter are settled in shares of Company common stock.  Stock options and SARs granted prior to 2017 cliff vest after two years. Stock options and SARs granted in 2017 have a three-year graded vesting feature, with one-third of the awards vesting each year.  The Company has elected the straight-line method of expense attribution for the stock options and SARs with the graded vesting feature.

Compensation expense recorded for all stock options, stock awards and SARs was as follows:

(In thousands)
Three Months Ended September 30				Nine Months Ended September 30
2017		2016		2017		2016
$	1,697	$	3,607	$	6,248	$	8,055

The decrease in stock-based compensation expense between the three-month periods ended September 30, 2017 and 2016, was primarily attributable to a decrease in cash-settled SARs compensation resulting from a decrease in the market price of Company common stock in the third quarter of 2017 versus an increase in the stock price of Company common stock in the third quarter of 2016. The above decrease in cash-settled SARs compensation was also the primary reason for the decline in stock-based compensation expense between the nine-month periods ended September 30, 2017 and 2016.

Unrecognized compensation costs for stock options, stock awards and SARs were as follows:

(In thousands)	September30, 2017		December 31, 2016
Stock options	$	1,533	$	895
Stock awards		4,632		5,514
SARs		3,178		1,859

The unrecognized compensation costs at September 30, 2017, are expected to be recognized over weighted-average periods of 2.0 years, 1.6 years and 2.0 years for stock options, stock awards and SARs, respectively.

Grants of the following awards were made during the nine months ended September 30, 2017:

Commitments And Contingencies Disclosure [Abstract]

Contingencies

7. CONTINGENCIES

There are a variety of legal proceedings pending or threatened against the Company.  Some of these proceedings may result in fines, penalties, judgments or costs being assessed against the Company at some future time.  The Company’s operations are subject to extensive local, state and federal regulations, including the U.S. Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA) and the Superfund amendments of 1986 (Superfund) and similar laws in the other countries in which the Company does business.  Over the years, the Company has received requests for information related to or has been named by the government as a potentially responsible party (PRP) at a number of waste disposal sites where cleanup costs have been or may be incurred under CERCLA and similar state statutes.  In addition, damages are being claimed against the Company in general liability actions for alleged personal injury or property damage in the case of some disposal and plant sites.  The Company believes that it has made adequate provisions for the costs it may incur with respect to these sites.

As of September 30, 2017, the Company estimated a range of possible environmental and legal losses of $25.0 million to $46.1million.  At September 30, 2017, and December 31, 2016, the Company’s accrued liability for such losses, which represented the Company’s best estimate within the estimated range of possible environmental and legal losses, was $25.0 million and $25.8 million, respectively. During the nine-month period ended September 30, 2017, cash outlays related to legal and environmental matters approximated $1.4 million compared to $1.0 million for the same period in 2016.

For certain sites, the Company has responded to information requests made by federal, state or local government agencies but has received no response confirming or denying the Company’s stated positions. As such, estimates of the total costs, or range of possible costs, of remediation, if any, or the Company’s share of such costs, if any, cannot be determined with respect to these sites. Consequently, the Company is unable to predict the effect thereof on the Company’s financial position, cash flows and results of operations.  Based upon the Company’s present knowledge with respect to its involvement at these sites, the possibility of other viable entities’ responsibilities for cleanup, and the extended period over which any costs would be incurred, the Company believes that these matters, individually and in the aggregate, will not have a material effect on the Company’s financial position.  However, in the event of one or more adverse determinations with respect to such sites in any annual or interim period, the effect on the Company’s cash flows and results of operations for those periods could be material.

Following are summaries of the material contingencies at September 30, 2017:

Maywood, New Jersey Site

The Company’s property in Maywood, New Jersey and property formerly owned by the Company adjacent to its current site and other nearby properties (Maywood site) were listed on the National Priorities List in September 1993 pursuant to the provisions of CERCLA because of certain alleged chemical contamination.  Pursuant to an Administrative Order on Consent entered into between United States Environmental Protection Agency (USEPA) and the Company for property formerly owned by the Company, and the issuance of an order by USEPA to the Company for property currently owned by the Company, the Company has completed various Remedial Investigation Feasibility Studies, and on September 24, 2014, USEPA issued its Record of Decision (ROD) for chemically-contaminated soil. USEPA has not yet issued a ROD for chemically-contaminated groundwater for the Maywood site. Based on the most current information available, the Company believes its recorded liability represents its best estimate of the cost of remediation for the Maywood site. The best estimate of the cost of remediation for the Maywood site could change as the Company continues to hold discussions with USEPA, as the design of the remedial action progresses or if other PRPs are identified. The ultimate amount for which the Company is liable could differ from the Company’s current recorded liability.

In April 2015, the Company entered into an Administrative Settlement Agreement and Administrative Order on Consent with USEPA which requires payment of certain costs and performance of certain investigative and design work for chemically-contaminated soil.  Based on the Company’s review and analysis of this order, no changes to the Company’s recorded liability for claims associated with soil remediation of chemical contamination were required.  

In addition, under the terms of a settlement agreement reached on November 12, 2004, the U.S. Department of Justice and the Company agreed to fulfill the terms of a Cooperative Agreement reached in 1985 under which the United States will take title to and responsibility for radioactive waste removal at the Maywood site, including past and future remediation costs incurred by the United States.  As such, the Company recorded no liability related to this settlement agreement.

D’Imperio Property Site

During the mid-1970’s, Jerome Lightman and the Lightman Drum Company disposed of hazardous substances at several sites in New Jersey.  The Company was named as a PRP in a lawsuit in the U.S. District Court for the District of New Jersey that involved the D’Imperio Property Site located in New Jersey.  In 2016, the PRPs were provided with updated remediation cost estimates which were considered in the Company’s determination of its range of estimated possible losses and liability balance.  The changes in range of possible losses and liability balance were immaterial.  Remediation work is continuing at this site.  Based on current information, the Company believes that its recorded liability represents its best estimate of the cost of remediation for the D’Imperio site.  Depending on the ultimate cost of the remediation at this site, the amount for which the Company is liable could differ from the current estimates.

Wilmington Site

The Company is currently contractually obligated to contribute to the response costs associated with the Company’s formerly-owned site at 51 Eames Street, Wilmington, Massachusetts.  Remediation at this site is being managed by its current owner, to whom the Company sold the property in 1980.  Under the agreement, once total site remediation costs exceed certain levels, the Company is obligated to contribute up to five percent of future response costs associated with this site with no limitation on the ultimate amount of contributions. To date, the Company has paid the current owner $2.5 million for the Company’s portion of environmental response costs. The Company has recorded a liability for its portion of the estimated remediation costs for the site.  The Company believes that based on current information its recorded liability represents the best estimate of its share of the remediation costs at this site. Depending on the ultimate cost of the remediation at this site, the amount for which the Company is liable could differ from the current recorded liability.

The Company and other prior owners also entered into an agreement in April 2004 waiving certain statute of limitations defenses for claims which may be filed by the Town of Wilmington, Massachusetts, in connection with this site.  While the Company has denied any liability for any such claims, the Company agreed to this waiver while the parties continue to discuss the resolution of any potential claim which may be filed.

Other U.S. Sites

Through the regular environmental monitoring of its plant production sites, the Company discovered levels of chemical contamination that were above thresholds allowed by law at two of its U.S. plants.  The Company voluntarily reported its results to the applicable state environmental agencies.  As a result, the Company is required to perform self-remediation of the affected areas.  In the fourth quarter of 2016, the Company established a liability for the estimated cost of remediating the sites.  Based on current information, the Company believes that its recorded liability represents its best estimate of the cost of remediation for these sites.  The ultimate cost of the remediation at this site could differ from the Company’s current recorded liability.

Employer Contributions

U.S. Plans

The Company made a $2,100,000 voluntary contribution to its funded U.S. qualified defined benefit plans in the three- and nine-month periods ended September 30, 2017. No other contributions are expected to be made to the funded plans in 2017. Approximately $312,000 is expected to be paid related to the unfunded non-qualified plans in 2017. Of such amount, $256,000 had been paid as of September 30, 2017.

U.K. Plan

The Company’s U.K. subsidiary expects to contribute approximately $360,000 to its defined benefit pension plan in 2017.  Of such amount, $281,000 had been contributed as of September 30, 2017.

Defined Contribution Plans

The Company sponsors retirement savings defined contribution plans that cover U.S. and U.K. employees. The Company also sponsors a qualified profit sharing plan for its U.S. employees. The retirement savings and profit sharing defined contribution plans include a qualified plan and a non-qualified supplemental executive plan.

Defined contribution plan expenses for the Company’s retirement savings and profit sharing plans were as follows:

(In thousands)	Three Months Ended September 30				Nine Months Ended September 30
	2017		2016		2017		2016
Retirement savings plans	$	1,275	$	1,304	$	3,758	$	3,849
Profit sharing plan		1,308		1,595		5,259		5,098
Total  defined contribution expense	$	2,583	$	2,899	$	9,017	$	8,947

The Company funds the obligations of its non-qualified supplemental executive defined contribution plans (supplemental plans) through a rabbi trust. The trust comprises various mutual fund investments selected by the participants of the supplemental plans. In accordance with the accounting guidance for rabbi trust arrangements, the assets of the trust and the obligations of the supplemental plans are reported on the Company’s consolidated balance sheets.  The Company elected the fair value option for the mutual fund investment assets so that offsetting changes in the mutual fund values and defined contribution plan obligations would be recorded in earnings in the same period. Therefore, the mutual funds are reported at fair value with any subsequent changes in fair value recorded in the consolidated statements of income. The liabilities related to the supplemental plans increase (i.e., supplemental plan expense is recognized) when the value of the trust assets appreciates and decrease when the value of the trust assets declines (i.e., supplemental plan income is recognized). At September 30, 2017, the balance of the trust assets was $1,502,000, which equaled the balance of the supplemental plan liabilities.

Restructuring And Related Activities [Abstract]

Business Restructuring

14. BUSINESS RESTRUCTURING

In May 2016, the Company announced plans to shut down its Longford Mills, Ontario, Canada (Longford Mills) manufacturing facility, a part of the Surfactant reportable segment, by December 31, 2016. The shutdown plan was developed as an effort to improve the Company’s asset utilization in North America and to reduce the Company’s fixed cost base. Manufacturing operations of the Longford Mills plant ceased by the end of 2016, and production of goods manufactured at the facility was transferred to other Company North American production sites. Decommissioning of the assets is expected to continue throughout the remainder of 2017. As of September 30, 2017, an aggregate of $4,483,000 of expense has been recognized since the beginning of the restructuring, reflecting $1,594,000 of termination benefits for approximately 30 employees and $2,889,000 for other expenses, principally asset decommissioning costs. The spending for the decommissioning of the assets is nearly complete. 

Below is a reconciliation of the December 31, 2016 and the September 30, 2017 restructuring liabilities:

(In thousands)	Termination Benefits			Other Expense			Total
Restructuring liability at December 31, 2016	$	1,548		$	437		$	1,985

Foreign currency translation		37			14			51
Restructuring liability at September 30, 2017	$	778		$	139		$	917

In addition to the above, the Company eliminated 11 positions from manufacturing operations at its Singapore plant in June 2017. The Singapore plant is part of the Company’s Surfactant segment. The reduction in positions was made to better align the number of personnel with current business requirements and to reduce costs at that site. As a result of the reduction in workforce, termination expense of $132,000 was recognized in the second quarter ended June 30, 2017. As of September 30, 2017, there was no remaining liability for the termination pay.

2017 Acquisition Agreement

On June 13, 2017, the Company announced that it had reached an agreement with BASF Mexicana, S.A. DE C.V. (BASF) to acquire BASF’s production facility in Ecatepec, Mexico, and a portion of its related surfactants business. The facility, which is near Mexico City, has over 50,000 metric tons of capacity, 124,000 square feet of warehouse space, a laboratory and office space. The acquisition is currently expected to be completed in the first quarter of 2018, subject to closing conditions.  The acquired facility and business will be included in the Company’s Surfactant segment.

2016 Business Acquisition

On October 3, 2016, the Company’s subsidiary in Brazil acquired the commercial business of Tebras Tensoativos do Brazil Ltda. (Tebras) and the sulfonation production facility of PBC Industria Quimica Ltda. (PBC). The acquired businesses are included in the Company’s Surfactants segment. The original purchase price of the acquisitions was R$93,309,000 (approximately $29,075,000), of which R$70,000,000 (approximately $21,812,000) was paid from cash on hand, R$9,000,000 (approximately $2,804,000) was deposited in escrow to cover certain potential losses as specified in the purchase agreement and R$14,309,000 (approximately $4,459,000) for working capital adjustments was unpaid pending agreement on the adjustment amounts.

In the first quarter of 2017, the Company settled on and paid the working capital adjustment amounts that were outstanding at December 31, 2016. The payment totaled R$13,925,000 (approximately $4,339,000), which made the adjusted purchase price of the acquisitions R$92,925,000 (approximately $28,955,000).

As a result of the change in purchase price, the amount of the purchase price allocated to goodwill changed from $14,327,000 to $14,207,000. The values of all other assets acquired and liabilities assumed remained as previously reported. In addition, the change in purchase price had no impact on the Company’s current or previously reported results of operations. The following table summarizes the assets acquired and liabilities assumed:

(In thousands)
Assets:
Current assets	$	5,165
Property, plant and equipment		5,716
Identifiable intangible assets		7,354
Goodwill		14,207
Total assets acquired	$	32,442
Liabilities:
Current liabilities	$	408
Deferred tax liability		3,079
Total liabilities assumed	$	3,487
Net assets acquired	$	28,955

The acquired goodwill, which was assigned entirely to the Company’s Surfactant segment, is not currently tax deductible. The goodwill reflects the opportunity of introducing the Company’s broad line of surfactant products to the acquired entities’ large customer base. Identifiable intangible assets included customer relationships ($4,331,000), a supply contract ($2,555,000) and non-compete agreements ($468,000). The amortization period for these intangibles at the time of acquisition were 13 years, four years and five years, respectively. The Company continues to evaluate the purchase price allocation, including the estimated fair values of assets acquired and liabilities assumed. Any changes to these amounts during the measurement period may result in an adjustment to the recorded amount of goodwill.

Accounting Changes And Error Corrections [Abstract]

Recent Accounting Pronouncements

16. RECENT ACCOUNTING PRONOUNCEMENTS

In May 2014, the Financial Accounting Standards Board (FASB) issued ASU No. 2014-9, Revenue from Contracts with Customers (Topic 606). The new update was later amended by ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. In addition, the ASU requires expanded disclosures about revenue recognition that enable the users of the financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. ASU No. 2014-09 supersedes most of the previous revenue recognition guidance. For public entities, the new guidance, as amended, is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. An entity may use either a full retrospective or a modified retrospective approach to adopt the requirements of the new standard. The Company expects to apply the modified retrospective approach. Although the Company continues the process of determining the effects, if any, that adoption of ASU No. 2014-9 will have on Company financial statements, adoption of the new guidance is not currently expected to have a material effect on the Company’s financial position, results of operations and cash flows. However, adoption of ASU No. 2014-9 is expected to affect the Company’s disclosures by requiring further disaggregation of revenue and additional insight about performance obligations.

  In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory, which requires an entity to measure inventory within the scope of the update at the lower of cost and net realizable value. Prior guidance required inventory to be measured at the lower of cost or market. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent measurement is unchanged for inventory measured using the last-in, first-out method or the retail inventory method. For public entities, ASU No. 2015-11 is effective prospectively for annual periods beginning after December 15, 2016, and interim periods therein. On January 1, 2017, the Company adopted ASU No. 2015-11, which did not have a material effect on the Company’s financial position, results of operations or cash flows.

In February 2016, the 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 will be 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. Early adoption is permitted. A modified retrospective approach is required for all leases existing or entered into after the beginning of the earliest comparative period in the consolidated financial statements. Most of the Company’s operating leases will be required to be placed on the balance sheet. The Company is assessing the quantitative impact that adoption of ASU No. 2016-2 will have on its financial position, results of operations and cash flows.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which adds or clarifies guidance on the classification of eight specific types of cash flows. The update is intended to reduce the existing diversity in practice with respect to the specific cash flow items. The amendments in ASU No. 2016-15 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company is assessing the impact that adoption of ASU No. 2016-15 will have on its cash flow presentation. ASU No. 2016-15 is not expected to have an effect on the Company’s financial position or results of operations.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. The update requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Current accounting guidance prohibits the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset has been sold to an outside party. The amendments in ASU No. 2016-16 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted for all entities as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued or made available for issuance.  The amendments in this update will be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company is assessing the impact that adoption of ASU No. 2016-16 will have on its financial position, results of operations and 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 amendments in ASU No. 2017-4 for annual, or any interim, goodwill impairment tests will be effective for fiscal years beginning after December 15, 2019. It is not expected that the adoption of the guidance in ASU No. 2017-4 will have a material effect on the Company’s financial position, results of operations or cash flows.

In March 2017, the FASB issued ASU No. 2017-7, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which amends existing guidance for the income statement presentation of the components of net periodic benefit cost for an entity’s sponsored defined benefit pension and other postretirement plans. The amended guidance requires entities to include the current service component of net periodic benefit cost in employee compensation costs in the income statement and to include all other components elsewhere in the income statement outside of income from operations. In addition, only the service cost component of net benefit cost is eligible for capitalization. For the Company, ASU No. 2017-7 is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted as of the beginning of any annual period for which an entity’s financial statements have not been issued. The requirements for the separate presentation of the service cost component and the other components of net periodic benefit cost must be adopted on a retrospective basis. The requirement to capitalize only the service component of net periodic benefit cost must be adopted on a prospective basis. Adoption of ASU No. 2017-7 will affect the presentation of the Company’s results of operations but will not have a material effect on the Company’s financial position or cash flows.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which amends previous guidance regarding hedge accounting recognition and presentation requirements. The updated guidance alters the hedge accounting model to make achieving hedge accounting easier for an entity and to have such accounting better reflect an entity’s risk management activities. ASU No. 2017-12 also adds new, and amends previous, disclosure requirements. For the Company, ASU No. 2017-12 is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. Entities must apply a modified retrospective approach to existing hedging relationships as of the adoption date. At present, because the Company has not entered into any transactions designated as accounting hedges, adoption of ASU No. 2017-12 is not expected to have a material effect on the Company’s financial position, results of operations and cash flows.

Accounting Changes And Error Corrections [Abstract]

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued ASU No. 2014-9, Revenue from Contracts with Customers (Topic 606). The new update was later amended by ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. In addition, the ASU requires expanded disclosures about revenue recognition that enable the users of the financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. ASU No. 2014-09 supersedes most of the previous revenue recognition guidance. For public entities, the new guidance, as amended, is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. An entity may use either a full retrospective or a modified retrospective approach to adopt the requirements of the new standard. The Company expects to apply the modified retrospective approach. Although the Company continues the process of determining the effects, if any, that adoption of ASU No. 2014-9 will have on Company financial statements, adoption of the new guidance is not currently expected to have a material effect on the Company’s financial position, results of operations and cash flows. However, adoption of ASU No. 2014-9 is expected to affect the Company’s disclosures by requiring further disaggregation of revenue and additional insight about performance obligations.

  In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory, which requires an entity to measure inventory within the scope of the update at the lower of cost and net realizable value. Prior guidance required inventory to be measured at the lower of cost or market. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent measurement is unchanged for inventory measured using the last-in, first-out method or the retail inventory method. For public entities, ASU No. 2015-11 is effective prospectively for annual periods beginning after December 15, 2016, and interim periods therein. On January 1, 2017, the Company adopted ASU No. 2015-11, which did not have a material effect on the Company’s financial position, results of operations or cash flows.

In February 2016, the 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 will be 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. Early adoption is permitted. A modified retrospective approach is required for all leases existing or entered into after the beginning of the earliest comparative period in the consolidated financial statements. Most of the Company’s operating leases will be required to be placed on the balance sheet. The Company is assessing the quantitative impact that adoption of ASU No. 2016-2 will have on its financial position, results of operations and cash flows.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which adds or clarifies guidance on the classification of eight specific types of cash flows. The update is intended to reduce the existing diversity in practice with respect to the specific cash flow items. The amendments in ASU No. 2016-15 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company is assessing the impact that adoption of ASU No. 2016-15 will have on its cash flow presentation. ASU No. 2016-15 is not expected to have an effect on the Company’s financial position or results of operations.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. The update requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Current accounting guidance prohibits the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset has been sold to an outside party. The amendments in ASU No. 2016-16 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted for all entities as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued or made available for issuance.  The amendments in this update will be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company is assessing the impact that adoption of ASU No. 2016-16 will have on its financial position, results of operations and 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 amendments in ASU No. 2017-4 for annual, or any interim, goodwill impairment tests will be effective for fiscal years beginning after December 15, 2019. It is not expected that the adoption of the guidance in ASU No. 2017-4 will have a material effect on the Company’s financial position, results of operations or cash flows.

In March 2017, the FASB issued ASU No. 2017-7, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which amends existing guidance for the income statement presentation of the components of net periodic benefit cost for an entity’s sponsored defined benefit pension and other postretirement plans. The amended guidance requires entities to include the current service component of net periodic benefit cost in employee compensation costs in the income statement and to include all other components elsewhere in the income statement outside of income from operations. In addition, only the service cost component of net benefit cost is eligible for capitalization. For the Company, ASU No. 2017-7 is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted as of the beginning of any annual period for which an entity’s financial statements have not been issued. The requirements for the separate presentation of the service cost component and the other components of net periodic benefit cost must be adopted on a retrospective basis. The requirement to capitalize only the service component of net periodic benefit cost must be adopted on a prospective basis. Adoption of ASU No. 2017-7 will affect the presentation of the Company’s results of operations but will not have a material effect on the Company’s financial position or cash flows.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which amends previous guidance regarding hedge accounting recognition and presentation requirements. The updated guidance alters the hedge accounting model to make achieving hedge accounting easier for an entity and to have such accounting better reflect an entity’s risk management activities. ASU No. 2017-12 also adds new, and amends previous, disclosure requirements. For the Company, ASU No. 2017-12 is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. Entities must apply a modified retrospective approach to existing hedging relationships as of the adoption date. At present, because the Company has not entered into any transactions designated as accounting hedges, adoption of ASU No. 2017-12 is not expected to have a material effect on the Company’s financial position, results of operations and cash flows.
