Summary Of Significant Accounting Policies (Policies) | 12 Months Ended
--- | ---
Dec. 31, 2018
Accounting Policies [Abstract] |
Basis Of Presentation | Basis of Presentation. The consolidated financial statements include the accounts and operations of Tredegar and all of its majority-owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with United States (“U.S.”) generally accepted accounting principles (“GAAP”) requires Tredegar to make estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. Certain amounts for the prior years have been reclassified to conform to current year presentation. For the years ended December 31, 2017 and 2016, the pension and postretirement benefit expenses recorded in Cost of goods sold and Selling, general and administrative have been reclassified to a new line item, Pension and postretirement benefits, on the consolidated statements of income, due to the retrospective adoption of ASU 2017-07.
Foreign Currency Translation | Foreign Currency Translation. The financial statements of subsidiaries located outside the U.S., where the local currency is the functional currency, are translated into U.S. Dollars using exchange rates in effect at the period end for assets and liabilities and average exchange rates during each reporting period for results of operations. Adjustments resulting from the translation of these financial statements are reflected as a separate component of shareholders’ equity. There are no operating subsidiaries located outside the U.S. where the U.S. Dollar is the functional currency. Transaction and remeasurement gains or losses included in income were losses of $0.5 million, $0.8 million and $3.6 million in 2018, 2017 and 2016, respectively. These amounts do not include the effects between reporting periods that exchange rate changes have on income of the locations outside the U.S. that result from translation into U.S. Dollars.
Cash And Cash Equivalents | Cash and Cash Equivalents. Cash and cash equivalents consist of cash on hand in excess of daily operating requirements and highly liquid investments with original maturities of three months or less. At December 31, 2018 and 2017, Tredegar had cash and cash equivalents of $34.4 million and $36.5 million, respectively, including funds held in locations outside the U.S. of $31.1 million and $32.7 million, respectively. The Company’s policy permits investment of excess cash in marketable securities that have the highest credit ratings and maturities of less than one year. The primary objectives of the policy are safety of principal and liquidity.
Accounts And Other Receivables | Accounts and Other Receivables. Accounts receivable are stated at the amount invoiced to customers less allowances for doubtful accounts and sales returns. Accounts receivable are non-interest bearing and arise from the sale of product to customers under typical industry trade terms. Notes receivable are not significant. Past due amounts are determined based on established terms and charged-off when deemed uncollectible. The allowance for doubtful accounts is determined based on an assessment of probable losses taking into account past due amounts, customer credit profile, historical experience and current economic conditions. Other receivables include value-added taxes related to certain foreign subsidiaries and other miscellaneous receivables due within one year. For certain customers, the Company has arrangements in place with financial institutions whereby certain customer receivables are sold to the financial institution at a discount and without recourse. Upon sale, the associated receivable is derecognized and the discount is recognized.
Inventories | Inventories. Inventories are stated at the lower of cost or market, with cost determined using the last-in, first-out (“LIFO”), the weighted average cost or the first-in, first-out method. Cost elements included in work-in-process and finished goods inventories are raw materials, direct labor and manufacturing overhead. Finished goods, work-in-process, raw materials and supplies, stores and other inventory are reviewed to determine if inventory quantities are in excess of forecasted usage or if they have become obsolete.
Property, Plant And Equipment | Property, Plant and Equipment. Accounts include costs of assets constructed or purchased, related delivery and installation costs and interest incurred on significant capital projects during their construction periods. Expenditures for renewals and betterments also are capitalized, but expenditures for repairs and maintenance are expensed as incurred. The cost and accumulated depreciation applicable to assets retired or sold are removed from the respective accounts, and gains or losses thereon are included in income. Capital expenditures for property, plant and equipment include capitalized interest. Capitalized interest included in capital expenditures for property, plant and equipment was $0.3 million, $0.4 million and $0.3 million in 2018, 2017 and 2016, respectively. Depreciation is computed primarily by the straight-line method based on the estimated useful lives of the assets that, except for isolated exceptions, range from 5 to 40 years for buildings and land improvements and 2 to 20 years for machinery and equipment.
Investments In Private Entities With Less Than Or Equal To 50% Voting Ownership Interest | Investments in Private Entities with Less Than or Equal to 50% Voting Ownership Interest. The Company accounts for its investments in private entities where its voting ownership is less than or equal to 50% based on the facts and circumstances surrounding the investment. For those investments measured at fair value, GAAP requires disclosure of the level within the fair value hierarchy in which fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets or liabilities (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3).
Goodwill And Other Intangibles | Goodwill and Identifiable Intangibles. The excess of the purchase price over the fair value of identifiable net assets of acquired companies is allocated to goodwill. The Company assesses goodwill for impairment when events or circumstances indicate that the carrying value may not be recoverable or, at a minimum, on an annual basis (December 1st of each year). When assessing goodwill for impairment, accounting guidance allows the Company to first perform a qualitative assessment about the likelihood of the carrying value of a reporting unit exceeding its fair value, referred to as the "Step 0" assessment. The Step 0 assessment requires the evaluation of certain qualitative factors, including macroeconomic conditions, industry and market considerations, cost factors and overall financial performance, as well as company and reporting unit factors. If the Company's Step 0 analysis indicates that it is more likely than not that the fair value of a reporting unit is less than the carrying amount, then the Company would perform a quantitative impairment test. The Company’s significant operating units in PE Films include Personal Care and Surface Protection. There are three operating units in Aluminum Extrusions: Bonnell Aluminum, AACOA and Futura. Each of these reporting units has separately identifiable operating net assets (operating assets including goodwill and identifiable intangible assets net of operating liabilities). The Company recorded a goodwill impairment charge of $46.8 million ($38.2 million after taxes) to write off the goodwill associated with the Personal Care reporting unit of PE Films in the third quarter of 2018. See Note 8 for additional details. The Company estimates the fair value of its reporting units using discounted cash flow analysis and comparative enterprise value-to-EBITDA (earnings before interest, taxes, depreciation and amortization) multiples. Goodwill of Aluminum Extrusions operating unit, Futura, in the amount of $10.4 million was tested for impairment at the annual testing date, with the estimated fair value of this reporting unit exceeding the carrying value of its net assets at December 1, 2018. The Surface Protection reporting unit of PE Films and the AACOA, Inc. (“AACOA”) reporting unit of Aluminum Extrusions had goodwill in the amounts of $57.3 million and $13.7 million, respectively, at December 1, 2018. The goodwill in Aluminum Extrusions is associated with the October 2012 acquisition of AACOA and the February 2017 acquisition of Futura Industries Corporation (“Futura”). As of December 31, 2018, the Company applied the Step 0 assessment to Surface Protection and AACOA, which both had fair values significantly in excess of their carrying amounts when tested in 2017. The Company's Step 0 analysis in 2018 of the reporting units concluded that it is not more likely than not that the fair values of the reporting units are less than their carrying amounts. Therefore, the quantitative goodwill impairment test for these reporting units was not necessary in 2018. Indefinite-lived identifiable intangible assets are assessed for impairment when events or circumstances indicate that the carrying value may not be recoverable. The Company estimates the fair value of its trade names using a relief-from-royalty method that relies upon a corresponding discounted cash flow analysis. For AACOA and Futura, the indefinite-lived identifiable intangible assets for each were assessed for indicators of impairment at the annual testing date. No indicators of impairment were identified. Based on a valuation analysis conducted in the fourth quarter of 2017, Terphane recorded an impairment of its assets. Indefinite-lived trade names for Terphane were written down by $4.0 million to $2.4 million and were assigned estimated useful lives of 5 to 13 years. Also, Terphane recorded a reduction of the carrying value of definite-lived identifiable intangible assets in the amount of $14.0 million. Additional disclosure of Tredegar goodwill and identifiable intangible assets and the impairments recorded in 2017 are included in Note 8.
Impairment Of Long-Lived Assets | Impairment of Long-Lived Assets. The Company reviews long-lived assets for possible impairment when events indicate that an impairment may exist. For assets that are held and used in operations, if events indicate that an asset may be impaired, the Company estimates the future unlevered pre-tax cash flows expected to result from the use of the asset and its eventual disposition. Assets are grouped for this purpose at the lowest level for which there are identifiable and independent cash flows. If the sum of these undiscounted pre-tax cash flows is less than the carrying amount of the asset group, an impairment loss is calculated. Measurement of the impairment loss is the amount by which the carrying amount exceeds the estimated fair value of the asset group. During the fourth quarter of 2017, in conjunction with annual business planning as well as valuation activities (including the use of discounted cash flow and comparative enterprise value-to-EBITDA multiple methods) and other efforts, the Company determined that the carrying value of Terphane’s remaining long-lived assets were impaired. Accordingly, the Company wrote down these assets based on an enterprise valuation for all of Terphane of approximately $30 million. This write-down resulted in a non-cash asset impairment loss recognized during the fourth quarter of 2017 of $101 million ($87 million after non-cash tax benefits). See Note 17 for more information on this impairment. Assets that are held for sale are reported at the lower of their carrying amount or estimated fair value less cost to sell, with an impairment loss recognized for any write-down required.
Pension Costs And Postretirement Benefit Costs Other Than Pensions | Pension Costs and Postretirement Benefit Costs Other than Pensions. Pension costs and postretirement benefit costs other than pensions have been accrued over the period employees provided service to Tredegar. Liabilities and expenses for pension plans and other postretirement benefits are determined using actuarial methodologies and incorporate significant assumptions, including the rate used to discount the future estimated liability, the long-term rate of return on plan assets, and several assumptions relating to the employee workforce. The Company recognizes the funded status of its pension and other postretirement plans in the accompanying consolidated balance sheets. Tredegar’s policy is to fund its pension plans at amounts not less than the minimum requirements of the Employee Retirement Income Security Act (“ERISA”) of 1974 and to fund postretirement benefits other than pensions when claims are incurred.
Revenue Recognition | Revenue Recognition. Revenue from the sale of products, which is shown net of estimated sales returns and allowances, is recognized at a point in time when control has passed to the customer. Control passes to the customer generally when the customer takes physical possession or when title passes if defined separately in the sales agreement. Amounts billed to customers related to freight are classified as sales in the accompanying consolidated statements of income. The cost of freight is classified as a separate line in the accompanying consolidated statements of income. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction between Tredegar and its customers (such as value-added taxes) are accounted for on a net basis and therefore excluded from revenues. See Note 5 for disaggregation of revenue by segment and type. See Note 6 for a table showing accounts and other receivables, net of allowance for bad debts and sales returns. For the year ended December 31, 2018, the Company had no material bad-debt expense and there were no material contract assets, contract liabilities or deferred contract costs recorded on the Consolidated Balance Sheet as of December 31, 2018. Payment terms start from the date of satisfaction of the performance obligation and vary from COD (cash on delivery) to 120 days. The Company’s contracts generally include one performance obligation, which is satisfied at a point in time. For the year ended December 31, 2018, revenue recognized from performance obligations related to prior periods (for example, changes in transaction price), was not material. Revenue expected to be recognized in any future period related to remaining performance obligations, excluding i) revenue pertaining to contracts that have an original expected duration of one year or less, ii) contracts where revenue is recognized as invoiced and iii) variable consideration related to unsatisfied performance obligations, is not expected to materially impact the Company’s financial results.
Research & Development ("R&D") Costs | Research & Development (“R&D”) Costs. R&D costs are expensed as incurred and include primarily salaries, wages, employee benefits, equipment depreciation, facility costs and the cost of materials consumed relating to R&D efforts. R&D costs include a reasonable allocation of indirect costs.
Income Taxes | Income Taxes. Income taxes are recognized during the period in which transactions enter into the determination of income for financial reporting purposes, with deferred income taxes being provided at enacted statutory tax rates on the differences between the financial reporting and tax bases of assets and liabilities (see Note 16). Tredegar’s policy is to accrue U.S. federal income taxes to the extent required under GAAP on unremitted earnings of all foreign subsidiaries where required. However, due to changes in the taxation of dividends under the Tax Cuts and Jobs Act (the “TCJA”) enacted by the U.S. government in December 2017, Tredegar only records U.S. federal income taxes on unremitted earnings of its foreign subsidiaries where Tredegar cannot take steps to eliminate any potential tax on future distributions from its foreign subsidiaries. Prior to the second quarter of 2016, deferred U.S. federal income taxes had not been recorded for the undistributed earnings for Terphane Limitada because the Company had intended to permanently reinvest these earnings. Due to concerns about the political and economic conditions in Brazil, Terphane Limitada began making cash distributions to the Company. During 2016, Terphane Limitada paid dividends totaling $13.3 million to the Company. Because of the accumulation of significant losses related to foreign currency translations at Terphane Limitada, there were no unrecorded deferred income tax liabilities associated with the U.S. federal income taxes and foreign withholding taxes on Terphane Limitada’s undistributed earnings as of December 31, 2018 and December 31, 2017. A valuation allowance is recorded in the period when the Company determines that it is more likely than not that all or a portion of deferred income tax assets may not be realized. The establishment and removal of a valuation allowance requires the Company to consider all positive and negative evidence and make a judgmental decision regarding the amount of valuation allowance required as of a reporting date. The benefit of an uncertain tax position is included in the accompanying financial statements when the Company determines that it is more likely than not that the position will be sustained, based on the technical merits of the position, if the taxing authority examines the position and the dispute is litigated. This determination is made on the basis of all the facts, circumstances and information available as of the reporting date.
Earnings Per Share | Earnings Per Share. Basic earnings per share is computed using the weighted average number of shares of common stock outstanding. Diluted earnings per share is computed using the weighted average common and potentially dilutive common equivalent shares outstanding, determined as follows:
| 2018 |  | 2017 |  | 2016
Weighted average shares outstanding used to compute basic earnings per share | 33,067,800 |  |  | 32,945,961 |  |  | 32,761,793 |
Incremental shares attributable to stock options and restricted stock | 24,674 |  |  | 5,327 |  |  | 13,279 |
Shares used to compute diluted earnings per share | 33,092,474 |  |  | 32,951,288 |  |  | 32,775,072 |
Incremental shares attributable to stock options and restricted stock are computed using the average market price during the related period. The average out-of-the-money options to purchase shares that were excluded from the calculation of incremental shares attributable to stock options and restricted stock were 726,475 in 2018 and 397,669 in 2017 and 128,200 in 2016.
Stock-Based Employee Compensation Plans | Stock-Based Employee Compensation Plans. Compensation expense is recorded on all share-based awards using its calculated fair value over the requisite service period under the graded-vesting method. The fair value of stock option awards was estimated as of the grant date using the Black-Scholes options-pricing model. The fair value of restricted stock awards was estimated as of the grant date using the closing stock price on that date. The assumptions used in this model for valuing Tredegar stock options granted in 2018 and 2017 (no grants in 2016) were as follows:
| 2018 |  | 2017
Dividend yield | 2.3 | % |  | 1.9 | %
Weighted average volatility percentage | 38.3 | % |  | 38.3 | %
Weighted average risk-free interest rate | 2.8 | % |  | 1.8 | %
Holding period (years): |  |  |
Officers | 5 |  |  | 5 |
Management | 5 |  |  | 5 |
Weighted average exercise price at date of grant (also weighted average market price at date of grant): |  |  |
Officers | $ | 19.35 |  |  | $ | 15.65 |
Management | $ | 19.35 |  |  | $ | 15.65 |
The dividend yield is the actual dividend yield on Tredegar’s common stock at the date of grant, which the Company believes is a reasonable estimate of the expected yield during the holding period. The expected volatility is based on the historical volatility of Tredegar’s common stock using a sequential period of historical data equal to the expected holding period of the option. The Company has no reason to believe that future volatility for this period is likely to differ from the past. The assumed risk-free interest rate is based on observed interest rates (zero coupon U.S. Treasury debt securities) appropriate for the expected holding period. In March 2016, the Financial Accounting Standards Board (“FASB”) issued Account Standards Update (“ASU”) 2016-09, which amended guidance to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company adopted the new guidance in the first quarter of 2017. Under the new guidance, excess tax benefits related to equity compensation were recognized in income tax expense (benefit) in the consolidated statements of income rather than in accumulated other comprehensive income in the consolidated balance sheets and were applied on a prospective basis. If these amounts had been included in the consolidated statements of income in previous years, net income would have been reduced by $1.1 million in 2016. Changes to the statements of cash flows related to the classification of excess tax benefits and employee taxes paid for share-based payment arrangements were implemented on a retrospective basis. In addition, the updated guidance allows the Company to make an accounting policy election to account for forfeitures as they occur. Previously, the Company was required to estimate forfeitures at the grant date, accounting for estimated forfeitures over the requisite service period. Tredegar stock options granted during 2018 and 2017 (no grants in 2016), and related estimated fair value at the date of grant, are as follows:
| 2018 |  | 2017
Stock options granted (number of shares): |  |  |
Officers | 425,228 |  |  | 151,992 |
Management | 25,855 |  |  | 57,559 |
Total | 451,083 |  |  | 209,551 |
Estimated weighted average fair value of options per share at date of grant: |  |  |
Officers | $ | 5.87 |  |  | $ | 4.69 |
Management | $ | 5.87 |  |  | $ | 4.69 |
Total estimated fair value of stock options granted (in thousands) | $ | 2,648 |  |  | $ | 983 |
Additional disclosure of Tredegar stock options is included in Note 12.
Financial Instruments | Financial Instruments. Tredegar uses derivative financial instruments for the purpose of hedging aluminum price volatility and currency exchange rate exposures that exist as part of transactions associated with ongoing business operations. The Company’s derivative financial instruments are designated as and qualify as cash flow hedges and are recognized in the accompanying balance sheet at fair value. A change in the fair value of the derivative that is highly effective and that is designated and qualifies as a cash flow hedge is recorded in other comprehensive income. Gains and losses reported in other comprehensive income (loss) are reclassified to earnings in the periods in which earnings are affected by the variability of cash flows of the hedged transaction. Such gains and losses are reported on the same line as the underlying hedged item, and the cash flows related to financial instruments are classified in the consolidated statements of cash flows in a manner consistent with those of the transactions being hedged. Any hedge ineffectiveness (which represents the amount by which the changes in the fair value of the derivative exceed the variability in the cash flows of the forecasted transaction) is recorded in current period earnings. The amount of gains and losses recognized for hedge ineffectiveness were not material in 2018, 2017 and 2016. The Company’s policy requires that it formally document all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking various hedge transactions. The Company also formally assesses (both at the hedge’s inception and on an ongoing basis) whether the derivatives that are used in hedging transactions have been highly effective in offsetting changes in the fair value or cash flows of hedged items and whether those derivatives may be expected to remain highly effective in future periods. When it is determined that a derivative is not (or has ceased to be) highly effective as a hedge, the Company discontinues hedge accounting prospectively. As a policy, Tredegar does not engage in speculative or leveraged transactions, nor does it hold or issue financial instruments for trading purposes. Additional disclosure of the utilization of derivative hedging instruments is included in Note 9.
Comprehensive Income (Loss) | Comprehensive Income (Loss). Comprehensive income (loss) is defined as net income or loss as adjusted by other comprehensive income or loss items. Other comprehensive income (loss) includes changes in foreign currency translation adjustments, unrealized gains and losses on derivative financial instruments, prior service costs and net gains or losses from pension and other postretirement benefit plans arising during the period and amortization of these prior service costs and net gain or loss adjustments, all recorded net of deferred income taxes.
