Accounting Policies [Abstract] |
Summary of significant accounting policies | Summary of significant accounting policies Basis of presentation The Consolidated Financial Statements include the accounts of Sonoco Products Company and its majority-owned subsidiaries (the “Company” or “Sonoco”) after elimination of intercompany accounts and transactions. Investments in affiliated companies in which the Company shares control over the financial and operating decisions, but in which the Company is not the primary beneficiary, are accounted for by the equity method of accounting. Income applicable to these equity investments is reflected in “Equity in earnings of affiliates, net of tax” in the Consolidated Statements of Income. The aggregate carrying value of equity investments is reported in “Other Assets” in the Company’s Consolidated Balance She ets and totale d $54,356 and $51,938 at December 31, 2021 and 2020, respectively. Affiliated companies over which the Company exercised a significant influence at December 31, 2021, included:
Entity | Ownership Interest Percentage at December 31, 2021
RTS Packaging JVCO | 35.0 | %
Cascades Conversion, Inc. | 50.0 | %
Cascades Sonoco, Inc. | 50.0 | %
Showa Products Company Ltd. | 22.2 | %
Papertech Energía, S.L. | 25.0 | %
Weidenhammer New Packaging, LLC | 40.0 | %
Also incl uded in the investment totals above is the Compan y’s 19.5% ownership in a small tubes and cores business in Chile and its 12.2% ownership in a small paper recycling business in Finland. As the Company is not able to exercise significant influence over these investees, the equity investments are accounted for under the measurement alternative (i.e., cost less impairment, adjusted for any qualifying observable price changes). These investments are not material either individually or in the aggregate. Estimates and assumptions The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Revenue recognition The Company records revenue generally at a point in time when control transfers to the customer either upon shipment or delivery, depending on the terms of sale. Additionally, in certain cases, control transfers over time in conjunction with production where the Company is entitled to payment with margin for products produced that are customer specific and without alternative use. For products that meet these two criteria, the Company recognizes over time revenue under the input method as goods are produced. The Company commonly enters into Master Supply Arrangements with customers to provide goods and/or services over specific time periods. Customers submit purchase orders with quantities and prices to create a contract for accounting purposes. Shipping and handling expenses are considered a fulfillment cost, and included in "Cost of Sales," and freight charged to customers is included in "Net Sales" in the Company's Consolidated Statements of Income. The Company has rebate agreements with certain customers. These rebates are recorded as reductions of sales and are accrued using sales data and rebate percentages specific to each customer agreement. Accrued customer rebates are included in "Accrued expenses and other" in the Company's Consolidated Balance Sheets. Payment terms under the Company's arrangements are typically short term in nature. The Company provides prompt payment discounts to certain customers if invoices are paid within a predetermined period. Prompt payment discounts are determinable within a short period after the originating sale and like sales returns, are treated as a reduction of revenue. Accounts receivable and allowance for doubtful accounts The Company’s trade accounts receivable are non-interest bearing and are recorded at the invoiced amounts. The allowance for doubtful accounts represents the Company’s best estimate of the amount of probable credit losses in existing accounts receivable. The Company performs an evaluation of lifetime expected credit losses inherent in its accounts receivable at each balance sheet date. Such an evaluation includes consideration of historical loss experience, trends in customer payment frequency, present economic conditions, and judgment about the future financial health of its customers and industry sector. The allowance for doubtful accounts is monitored on a regular basis and adjustments are made as needed to ensure that the account properly reflects the Company’s best estimate of uncollectible trade accounts receivable. Account balances are charged off against the allowance for doubtful accounts when the Company determines that the receivable will not be recovered. Sales to the Company’s largest custo mer accounted for approximately 4% of the Company’s net sales in 2021, 4% in 2020 and 5% in 2019, primarily in the Consumer Packaging segment. Receivables from the largest customer accounted for approximately 3% of the Company’s total trade accounts receivable at December 31, 2021 and 3% at December 31, 2020. The Company’s next largest customer comprised approximately 3% of the Co mpany’s net sales in 2021, 4% in 2020 and 4% in 2019. Certain of the Company’s customers sponsor and actively promote multi-vendor supply chain finance arrangements and, in a limited number of cases, the Company has agreed to participate. Accordingly, approximately 10% a nd 11% of consolidated annual sales were settled under these arrangements in 2021 and 2020, respectively. Accounts payable and supply chain financing The Company facilitates a voluntary supply chain financing program (the "program") to provide certain of its suppliers with the opportunity to sell receivables due from the Company to the participating financial institution in the program. Such sales are conducted at the sole discretion of both the suppliers and the financial institution on a non-recourse basis at a rate that leverages the Company's credit rating and thus might be more beneficial to the supplier. No guarantees are provided by the Company or any of our subsidiaries under the program. The Company's responsibility is limited to making payment on the terms originally negotiated with its suppliers, regardless of whether the suppliers sell their receivables to the financial institution. The Company does not enter into any agreements with suppliers regarding their participation in the program. The amount owed to the participating financial institution under the program and included in accounts payable was $46,832 at December 31, 2021 and $38,900 at December 31, 2020. Research and development Research and development costs are charged to expense as incurred and include salaries and other directly related expenses. Research and development costs totaling approximately $24,100 in 2021, $22,000 in 2020 and $23,300 in 2019 are included in “Selling, general and administrative expenses” in the Company’s Consolidated Statements of Income. Restructuring and asset impairment Costs associated with exit or disposal activities are recognized when the liability is incurred. If assets become impaired as a result of a restructuring action, the assets are written down to fair value, less estimated costs to sell, if applicable. A number of significant estimates and assumptions are involved in the determination of fair value. The Company considers historical experience and all available information at the time the estimates are made; however, the amounts that are ultimately realized upon the sale of divested assets may differ from the estimated fair values reflected in the Company’s Consolidated Financial Statements. Cash and cash equivalents Cash equivalents are composed of highly liquid investments with an original maturity to the Company of three months or less when purchased. Cash equivalents are recorded at cost, which approximates fair market value. As part of its cash management system, the Company uses “zero balance” accounts to fund disbursements. Under this system, the bank balance is zero at the end of each day, while the book balance is usually a negative amount due to reconciling items such as outstanding checks. Changes in these book cash overdrafts are reported as cash flows from financing activities. The Company’s cash and cash equivalents are primarily placed with large sophisticated credit-worthy financial institutions thereby limiting the Company’s credit exposure. Inventories The majority of the Company's inventories are accounted for using the first-in, first-out (FIFO) method and are stated at the lower of cost or net realizable value. The last-in, first-out (LIFO) method is used for the valuation of certain of the Company’s domestic inventories, primarily metal, internally manufactured paper and paper purchased from third parties, and a pproximated 15% and 15% o f total inventories at December 31, 2021 and 2020, respectively. Inventories accounted for using the LIFO method are stated at the lower of cost or market. If the FIFO method of accounting had been used for all inventories, total inventory would have been hi gher by $22,900 and $20,371 at December 31, 2021 and 2020, respectively. Property, plant and equipment Plant assets represent the original cost of land, buildings and equipment, less depreciation, computed under the straight-line method over the estimated useful lives of the assets, and are reviewed for impairment whenever events indicate the carrying value may not be recoverable. Equipment lives generally range from 3 to 11 years, and buildings range from 15 to 40 years. Expenditures for repairs and maintenance are charged to expense as incurred. When properties are retired or otherwise disposed of, the cost and accumulated depreciation are eliminated from the asset and related allowance accounts. Gains or losses are credited or charged to income as incurred. Timber resources are stated at cost. Depletion is charged to operations based on the estimated number of units of timber cut during the year. Leases At the inception of a contract, the Company assesses whether the contract is, or contains, a lease. The assessment is based on (1) whether the contract involves the use of a distinct identified asset, (2) whether the Company obtains the right to substantially all the economic benefit from the use of the asset throughout the period, and (3) whether the Company has the right to direct the use of the asset. When the Company determines a lease exists, a leased asset and corresponding lease liability are recorded on its consolidated balance sheet. Lease contracts with a term of 12 months or less are not recorded on the consolidated balance sheet. Leased assets represent the Company’s right to use an underlying asset during the lease term, and lease liabilities represent the Company’s obligation arising from the lease. The Company’s leased assets and liabilities may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise those options. The Company has lease agreements with non-lease components that relate to lease components (e.g., common area maintenance such as cleaning or landscaping, etc.). The Company accounts for each lease and any non-lease components associated with that lease as a single lease component for all underlying asset classes in accordance with the scope of the lease accounting standard. Leased assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the implicit rate in the Company's leases is not readily determinable, the Company calculates its lease liabilities using discount rates based upon the Company’s incremental secured borrowing rate, which contemplates and reflects a particular geographical region’s interest rate for the leases active within that region of the Company’s global operations. The Company further utilizes a portfolio approach by assigning a “short” rate to contracts with lease terms of 10 years or less and a “long” rate for contracts greater than 10 years. Lease payments may be fixed or variable, however, only fixed payments or in-substance fixed payments are included in determining the lease liability. Variable lease payments are recognized in operating expenses in the period in which the obligation for those payments is incurred. The Company recognizes fixed lease expense for operating leases on a straight-line basis over the lease term. For finance leases, the Company recognizes interest expense on the lease liability over the lease term and the finance lease asset balance is amortized on a straight-line basis. Goodwill The Company assesses its goodwill for impairment annually during the third quarter, or from time to time when warranted by the facts and circumstances surrounding individual reporting units or the Company as a whole. In performing the impairment test, the Company compares the fair value of the reporting unit with its carrying amount and recognizes an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. This quantitative test considers factors such as the amount by which estimated fair value exceeds current carrying value, current year operating performance as compared to prior projections, and implied fair values from comparable trading and transaction multiples. In determining the fair value of the reporting units, management considered both the income approach and the market approach. Fair value was estimated using a discounted cash flow model based on projections of future years’ operating results and associated cash flows combined with comparable trading and transaction multiples based on guideline public companies. The calculated estimated fair value of the reporting unit reflects a number of significant management assumptions and estimates including the forecast of sales growth, gross profit margins, and discount rates. Changes in these assumptions could materially impact the estimated fair value. The Company's projections incorporate management's best estimates of the expected future results, which include expectations related to new and retained business and future operating margins. Projected future cash flows are then discounted to present value using a discount rate management believes is commensurate with the risks inherent in the cash flows. If the fair value of a reporting unit exceeds the carrying value of the reporting unit’s assets, including goodwill, there is no impairment. If the carrying value of the reporting unit exceeds the fair value of that reporting unit, an impairment charge is recognized for the excess. Goodwill is not amortized. Impairment of long-lived, intangible and other assets Intangible assets are amortized, usually on a straight-line basis, over their respective useful lives, which generally range from 3 to 40 years. The Company has no intangibles with indefinite lives. The Company evaluates its intangible assets for impairment whenever indicators of impairment exist. Assumptions and estimates used in the evaluation of potential impairment can result in adjustments affecting the carrying values of long-lived, intangible and other assets and the recognition of impairment expense in the Company’s Consolidated Financial Statements. The Company evaluates its long-lived assets (property, plant and equipment), definite-lived intangible assets and other assets (including right of use lease assets, notes receivable and equity investments) for impairment whenever indicators of impairment exist, or when it commits to sell the asset. If the sum of the undiscounted expected future cash flows from a long-lived asset or definite-lived intangible asset group is less than the carrying value of that asset group, an asset impairment charge is recognized. Key assumptions and estimates used in the projection of expected future cash flows generally include price levels, sales growth, profit margins and asset life. The amount of an impairment charge, if any, is calculated as the excess of the asset’s carrying value over its fair value, generally represented by the discounted future cash flows from that asset or, in the case of assets the Company evaluates for sale, estimated sale proceeds less costs to sell. The Company takes into consideration historical data and experience together with all other relevant information available when estimating the fair values of its assets. However, fair values that could be realized in actual transactions may differ from the estimates used to evaluate impairment. In addition, changes in the assumptions and estimates may result in a different conclusion regarding impairment. Income taxes The Company provides for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting requirements and tax laws. Assets and liabilities are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company recognizes liabilities for uncertain income tax positions based on our estimate of whether it is more likely than not that additional taxes will be required and we report related interest and penalties as income taxes. Derivatives The Company uses derivatives to mitigate the effect of fluctuations in some of its raw material and energy costs, foreign currencies, and, from time to time, interest rates. The Company purchases commodities such as metal and energy, generally at market or at fixed prices that are established with the vendor as part of the purchase process for quantities expected to be consumed in the ordinary course of business. The Company may enter into commodity futures or swaps to manage the effect of price fluctuations. The Company may use foreign currency forward contracts and other risk management instruments to manage exposure to changes in foreign currency cash flows and the translation of monetary assets and liabilities on the Company’s consolidated financial statements. The Company is exposed to interest-rate fluctuations as a result of using debt as a source of financing for its operations. The Company may from time to time use traditional, unleveraged interest rate swaps to manage its exposure to interest rate movements. Additionally, the Company elected the normal purchase, normal sale scope exception for physical commodity contracts that meet the definition of a derivative. Derivative instruments, to the extent in an asset position, expose the Company to credit loss in the event of nonperformance by the counterparties to the derivative agreements. The Company manages its exposure to counterparty credit risk through minimum credit standards, diversification of counterparties and procedures to monitor concentrations of credit risk. The Company may enter into financial derivative contracts that may contain credit-risk-related contingent features, which could result in a counterparty requesting immediate payment or demanding immediate and ongoing full overnight collateralization on derivative instruments in net liability positions. The Company records its derivatives as assets or liabilities on the balance sheet at fair value using published market prices or estimated values based on current price and/or rate quotes and discounted estimated cash flows. Changes in the fair value of derivatives are recognized either in net income or in other comprehensive income, depending on whether the derivative is designated in a cash flow or net investment hedging relationship or not. Amounts in accumulated other comprehensive income are reclassified into earnings in the same period or periods during which the hedged forecasted transaction affects earnings. It is the Company’s policy not to speculate in derivative instruments. Business combinations The Company’s acquisitions of businesses are accounted for in accordance with ASC 805, "Business Combinations." The Company recognizes the identifiable assets acquired, the liabilities assumed, and any noncontrolling interests in an acquired business at their fair values as of the date of acquisition. Goodwill is measured as the excess of consideration transferred, also measured at fair value, over the net of the acquisition date fair values of the identifiable assets acquired and liabilities assumed. The acquisition method of accounting requires the Company to make significant estimates and assumptions regarding the fair values of the elements of a business combination as of the date of acquisition, including the fair values of identifiable intangible assets, deferred tax asset valuation allowances, liabilities including those related to debt, pensions and other postretirement plans, uncertain tax positions, contingent consideration and contingencies. This method also requires the Company to refine these estimates over a measurement period not to exceed one year to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. If the Company is required to adjust provisional amounts that were recorded for the fair values of assets and liabilities in connection with acquisitions, these adjustments could have a material impact on our financial condition and results of operations. Significant estimates and assumptions in estimating the fair value of acquired customer relationships, technology, and other identifiable intangible assets include future cash flows that the Company expects to generate from the acquired assets, discount rate, customer attrition rate, and long-term revenue growth projections. If the subsequent actual results and updated projections of the underlying business activity change compared with the assumptions and projections used to develop these values, the Company could record impairment charges. In addition, the Company has estimated the economic lives of certain acquired assets and these lives are used to calculate depreciation and amortization expense. If the estimates of the economic lives change, depreciation or amortization expenses could be increased or decreased, or the acquired asset could be impaired. Reportable segments The Company identifies its reportable segments by evaluating the level of detail reviewed by the chief operating decision maker, gross profit margins, nature of products sold, nature of the production processes, type and class of customer, methods used to distribute products, and nature of the regulatory environment. Of these factors, the Company believes that the most significant in determining the aggregation of operating segments are the nature of the products and the type of customers served. The Company changed its operating and reporting structure in January 2021 and, as a result, realigned certain of its reportable segments effective January 1, 2021. The revised structure consists of two reportable segments, Consumer Packaging and Industrial Paper Packaging, with all remaining businesses reported as All Other. Segment financial information for prior periods has been recast to conform to the current-year presentation. Contingencies Pursuant to U.S. GAAP for accounting for contingencies, accruals for estimated losses are recorded at the time information becomes available indicating that losses are probable and that the amounts are reasonably estimable. Amounts so accrued are not discounted.
