Principles of consolidation: All majority-owned subsidiaries are included in the Company's consolidated financial statements, with appropriate elimination of intercompany balances and transactions. Investments in associated companies (less than majority-owned and in which the Company has significant influence) are accounted for under the equity method. The Company's share of net income or losses in these investments in associated companies is included in the Consolidated Statement of Income. The Company periodically reviews these investments for impairments and, if necessary, would adjust these investments to their fair value when a decline in market value or other impairment indicators are deemed to be other than temporary. As described in Note 4 of Notes to Consolidated Financial Statements, during 2012 the Company acquired an increased ownership percentage in Primex, Ltd. (“Primex”), a captive insurance company. Due to the increased ownership percentage and other factors, the Company changed its method of accounting for its investment in Primex from the cost method to the equity method of accounting. As a result, the Company recast its Consolidated Balance Sheet as of December 31, 2011, the Consolidated Statements of Income, Other Comprehensive Income and Cash Flows for the years ending December 31, 2010 and December 31, 2011 and the Consolidated Statement of Changes in Equity for the years ending December 31, 2009, December 31, 2010 and December 31, 2011 and the Notes to Consolidated Financial Statements to reflect the change in method of accounting. See also Note 4 to Notes to Consolidated Financial Statements.

The Financial Accounting Standards Board's (“FASB's”) guidance regarding the consolidation of certain Variable Interest Entities (“VIEs”) generally requires that assets, liabilities and results of the activities of a VIE be consolidated into the financial statements of the enterprise that is considered the primary beneficiary. The consolidated financial statements include the accounts of the Company and all of its subsidiaries in which a controlling interest is maintained and would include any VIEs if the Company was the primary beneficiary pursuant to the provisions of the applicable guidance.

Translation of foreign currency: Assets and liabilities of non-U.S. subsidiaries and associated companies are translated into U.S. Dollars at the respective rates of exchange prevailing at the end of the year. Income and expense accounts are translated at average exchange rates prevailing during the year. Translation adjustments resulting from this process are recorded directly in equity as accumulated other comprehensive income (loss) and will be included as income or expense only upon sale or liquidation of the underlying investment. All non-U.S. subsidiaries use their local currency as their functional currency.

Cash and cash equivalents: The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents.

Inventories: Inventories are valued at the lower of cost or market value, and are valued using the first-in, first-out (“FIFO”) method. See also Note 6 of Notes to Consolidated Financial Statements.

Long-lived assets: Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line method on an individual asset basis over the following estimated useful lives: buildings and improvements, 10 to 45 years; and machinery and equipment, 1 to 15 years. The carrying value of long-lived assets is periodically evaluated whenever changes in circumstances or current events indicate the carrying amount of such assets may not be recoverable. An estimate of undiscounted cash flows produced by the asset, or the appropriate group of assets, is compared with the carrying value to determine whether impairment exists. If necessary, the Company recognizes an impairment loss for the difference between the carrying amount of the assets and their estimated fair value. Fair value is based on current and anticipated future undiscounted cash flows. Upon sale or other dispositions of long-lived assets, the applicable amounts of asset cost and accumulated depreciation are removed from the accounts and the net amount, less proceeds from disposals, is recorded in income. Expenditures for renewals or improvements that increase the estimated useful life or capacity of the assets are capitalized, whereas expenditures for repairs and maintenance are expensed when incurred.

Capitalized software: The Company capitalizes certain costs incurred in connection with developing or obtaining software for internal use. In connection with the upgrade and implementations of the Company's global transaction and consolidation systems, approximately $2,395 and $2,800 of net costs were capitalized at December 31, 2012 and December 31, 2011, respectively. These costs are amortized over a period of three to five years once the assets are ready for their intended use.

Goodwill and other intangible assets: The Company records goodwill, definite-lived intangible assets and indefinite-lived intangible assets at fair value at acquisition. Goodwill and indefinite-lived intangible assets are not amortized, but tested for impairment at least annually. These tests will be performed more frequently if triggering events indicate potential impairment. Definite-lived intangible assets are amortized over their estimated useful lives, generally for periods ranging from 5 to 20 years. The Company continually evaluates the reasonableness of the useful lives of these assets. See Note 17 of Notes to Consolidated Financial Statements.

Revenue recognition: The Company recognizes revenue in accordance with the terms of the underlying agreements, when title and risk of loss have been transferred, when collectability is reasonably assured, and when pricing is fixed or determinable. This generally occurs when products are shipped to customers or, for consignment-type arrangements, upon usage by the customer and when services are performed. License fees and royalties are included in other income when recognized in accordance with their agreed-upon terms, when performance obligations are satisfied, when the amount is fixed or determinable, and when collectability is reasonably assured. As part of the Company's chemical management services, certain third-party product sales to customers are managed by the Company. Where the Company acts as a principal, revenues are recognized on a gross reporting basis at the selling price negotiated with customers. Where the Company acts as an agent, such revenue is recorded using net reporting as service revenue at the amount of the administrative fee earned by the Company for ordering the goods. Third-party products transferred under arrangements resulting in net reporting totaled $39,299, $50,893 and $56,528 for 2012, 2011 and 2010, respectively.

Accounts receivable and allowance for doubtful accounts: Trade accounts receivable are recorded at the invoiced amount and generally do not bear interest. The allowance for doubtful accounts is the Company's best estimate of the amount of probable credit losses with its existing accounts receivable. Reserves for customers filing for bankruptcy protection are generally established at 75-100% of the amount owed at the filing date, dependent on the Company's evaluation of likely proceeds from the bankruptcy process. Large and/or financially distressed customers are generally reserved for on a specific review basis while a general reserve is established for other customers based on historical experience. The Company performs a formal review of its allowance for doubtful accounts quarterly. Account balances are charged off against the allowance when the Company feels it is probable the receivable will not be recovered. The Company does not have any off-balance-sheet credit exposure related to its customers. During 2012, the Company's five largest customers accounted for approximately 19% of its consolidated net sales with the largest customer (Arcelor-Mittal Group) accounting for approximately 9% of consolidated net sales.

During 2012, the Company recorded charges of $1,254 to its allowance for doubtful accounts and selling, general and administrative expenses due to the bankruptcies of two U.S. customers. See Note 5 of Notes to Consolidated Financial Statements.

Research and development costs: Research and development costs are expensed as incurred. Research and development expenses are included in selling, general and administrative expenses and were $19,993, $18,812 and $15,690 in 2012, 2011 and 2010, respectively.

Concentration of credit risk: Financial instruments, which potentially subject the Company to a concentration of credit risk, principally consist of cash equivalents, short-term investments and trade receivables. The Company invests temporary and excess funds in money market securities and financial instruments having maturities typically within 90 days. The Company has not experienced losses from the aforementioned investments.

Environmental liabilities and expenditures: Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. If there is a range of estimated liability and no amount in that range is considered more probable than another, then the Company records the lowest amount in the range in accordance with generally accepted accounting principles. Accrued liabilities are exclusive of claims against third parties and are not discounted. Environmental costs and remediation costs are capitalized if the costs extend the life, increase the capacity or improve safety or efficiency of the property from the date acquired or constructed, and/or mitigate or prevent contamination in the future.

Asset retirement obligations: The Company follows the FASB's guidance regarding asset retirement obligations, which addresses the accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated retirement costs. Also, the Company follows the FASB's guidance for conditional asset retirement obligations (“CARO”), which relates to legal obligations to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity. In accordance with this guidance, the Company records a liability when there is enough information regarding the timing of the CARO to perform a probability-weighted discounted cash flow analysis. See Note 9 of Notes to Consolidated Financial Statements.

Pension and other postretirement benefits: The Company maintains various noncontributory retirement plans, the largest of which is in the U.S., covering substantially all of its employees in the U.S. and certain other countries. The plans of the Company's subsidiaries in The Netherlands, the United Kingdom and Mexico are subject to the provisions of FASB's guidance regarding employers' accounting for pension plans. The plans of the remaining non-U.S. subsidiaries are, for the most part, either fully insured or integrated with the local governments' plans and are not subject to the provisions of the guidance. The guidance requires that employers recognize on a prospective basis the funded status of their defined benefit pension and other postretirement plans on their consolidated balance sheet, and, also, recognize as a component of other comprehensive income, net of tax, the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic benefit cost. The Company's U.S. pension plan year ends on November 30 and the measurement date is December 31. The measurement date for the Company's other postretirement benefits plan is December 31. See Note 11 of Notes to Consolidated Financial Statements.

Comprehensive income (loss): The Company presents other comprehensive loss in its Statement of Comprehensive Income. The components of accumulated other comprehensive loss at December 31, 2012 include: accumulated foreign currency translation adjustments of $3,336, minimum pension liability of ($46,914), unrealized holding gains on available-for-sale securities of $1,723. The components of accumulated other comprehensive loss at December 31, 2011 include: accumulated foreign currency translation adjustments of $4,709, minimum pension liability of ($34,260), unrealized holding gains on available-for-sale securities of $857, and the fair value of derivative instruments of ($272).

The items in other comprehensive loss in the Statement of Consolidated Comprehensive Income are net of tax benefits related to defined benefit retirement plans of $4,310, $2,223 and $1,342 for 2012, 2011 and 2010, respectively. Additionally, the items in other comprehensive loss in the Statement of Consolidated Comprehensive Income are net of tax benefits related to changes in the fair value of derivatives of $146, $213 and $381 for 2012, 2011 and 2010, respectively. Also, the items in other comprehensive loss in the Statement of Comprehensive Income are net of tax benefits (expense) related to changes in unrealized holding gains (losses) on available-for-sale securities of $446, ($71) and $128 for 2012, 2011 and 2010, respectively.

Income taxes and uncertain tax positions: The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year and the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of the Company's assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. The FASB's guidance regarding accounting for uncertainty in income taxes prescribes the recognition threshold and measurement attributes for financial statement recognition and measurement of tax positions taken or expected to be taken on a tax return. The guidance further requires the determination of whether the benefits of tax positions will be more likely than not sustained upon audit based upon the technical merits of the tax position. For tax positions that are determined to be more likely than not sustained upon audit, a company recognizes the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement in the financial statements. For tax positions that are not determined to be more likely than not sustained upon audit, a company does not recognize any portion of the benefit in the financial statements. Additionally, the guidance provides for derecognition, classification, penalties and interest, accounting in interim periods, disclosure and transition. The guidance also requires that the amount of interest expense and income to be recognized related to uncertain tax positions be computed by applying the applicable statutory rate of interest to the difference between the tax position recognized, including timing differences, and the amount previously taken or expected to be taken in a tax return. The Company's continuing practice is to recognize interest and/or penalties related to income tax matters in income tax expense. See Note 10 of Notes to Consolidated Financial Statements.

Derivatives: The Company is exposed to the impact of changes in interest rates, foreign currency fluctuations, changes in commodity prices and credit risk. The Company does not use derivative instruments to mitigate the risks associated with foreign currency fluctuations, changes in commodity prices or credit risk, but has used derivative financial instruments primarily for purposes of hedging exposures to fluctuations in interest rates. The Company recognizes all derivatives on its balance sheet at fair value. For derivative instruments designated as cash flow hedges, the effective portion of any hedge is reported in Accumulated Other Comprehensive Income (Loss) until it is cleared to earnings during the same period in which the hedged item affects earnings. The Company uses no derivative instruments designated as fair value hedges. The Company does not enter into derivative contracts for trading or speculative purposes. See Note 3 of Notes to Consolidated Financial Statements.

Fair value measurements: The Company utilizes the FASB's guidance regarding fair value measurements, which establishes a common definition for fair value to be applied to guidance requiring use of fair value, establishes a framework for measuring fair value and expands disclosure about such fair value measurements. Specifically, the guidance utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:

	•	Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.

	•	Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

	•	Level 3: Unobservable inputs that reflect the reporting entity's own assumptions.

Stock-based compensation: The Company applies the FASB's guidance regarding share-based payments, which requires the recognition of the fair value of stock compensation in net income. The Company elected the modified prospective method in adopting the guidance. Under this method, the provisions of the guidance apply to all awards granted or modified after the date of adoption. In addition, the unrecognized expense of awards not yet vested at the date of adoption is recognized in net income in the periods after the date of adoption using the same valuation method (e.g. Black-Scholes) and assumptions determined under the original provisions of the guidance as disclosed in the Company's previous filings.

The Company has a long-term incentive program (“LTIP”) for key employees which provides for the granting of options to purchase stock at prices not less than market value on the date of the grant. Most options become exercisable between one and three years after the date of the grant for a period of time determined by the Company, but not to exceed seven years from the date of grant. Common stock awards issued under the LTIP program are subject only to time vesting over a three to five-year period. In addition, as part of the Company's Global Annual Incentive Plan (“GAIP”), nonvested shares may be issued to key employees, which generally vest over a two to five-year period.

Based on historical experience, the Company has assumed a forfeiture rate of 13% on the nonvested stock. The Company will record additional expense if the actual forfeiture rate is lower than estimated, and will record a recovery of prior expense if the actual forfeiture is higher than estimated. See Note 13 of Notes to Consolidated Financial Statements.

Earnings per share: The Company follows FASB's guidance regarding the calculation of earnings per share (“EPS”) for nonvested stock awards with rights to non-forfeitable dividends. The guidance requires nonvested stock awards with rights to non-forfeitable dividends to be included as part of the basic weighted average share calculation under the two-class method. See Note 14 of Notes to Consolidated Financial Statements.

Segments: The Company organizes its segments by the nature of the product sold. The Company's reportable segments are as follows:

	•	Metalworking process chemicals—generally includes industrial process fluids for various heavy industrial and manufacturing applications.

	•	Coatings—generally includes temporary and permanent coatings for metal and concrete products and chemical milling maskants.

	•	Other chemical products—other various chemical products.

Segment data includes direct segment costs, as well as general operating costs. Any inter-segment transactions are immaterial for each period presented. See Note 15 of Notes to Consolidated Financial Statements.

The FASB updated its guidance in July 2012 regarding indefinite-lived intangible asset impairment testing. The updated guidance permits a Company to first assess qualitative factors to determine whether it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying value. If the Company determines that the fair value is more likely than not above its carrying value, no further impairment testing is required. However, if the Company concludes otherwise, then the first step of the traditional two-step impairment test is required to be performed. The guidance is effective for annual and interim fiscal periods beginning after September 15, 2012, with early adoption permitted if an entity's financial statements have not been issued as of the date of the entity's interim or annual impairment test. The Company elected to test its indefinite-lived intangible assets for impairment under the traditional two-step method during the current year but is currently evaluating the effect of this guidance for future applicability.

The FASB updated its guidance in December 2011 regarding disclosures pertaining to the netting and offsetting of derivatives and financial instruments on an entity's Consolidated Balance Sheet. Disclosures required under the updated guidance include presenting gross amounts of assets and liabilities related to financial instruments that may have been historically offset on the Consolidated Balance Sheet. The guidance is effective for annual and interim fiscal periods beginning on or after January 1, 2013. The Company is currently evaluating the effect of this guidance.

Reclassifications: During 2012, the Company adopted the FASB's guidance regarding presentation of comprehensive income. The guidance requires that comprehensive income be presented with the Consolidated Statement of Income or as a separate statement immediately following the Consolidated Statement of Income, and can no longer be presented as part of the Consolidated Statement of Changes in Equity. The Company adopted the guidance using the two statement approach. The guidance required retrospective application, so the prior periods' presentation of comprehensive income has been conformed to the current year presentation. In addition, certain other information has been reclassified to conform to the current year presentation.

Accounting estimates: The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosure of contingencies at the date of the financial statements and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from such estimates.
