Principles of Consolidation
We consolidate entities in which we own or control more than 50% of the voting shares or otherwise have the ability to control through similar rights. All intercompany transactions have been eliminated. The results of companies acquired or disposed of are included on the Consolidated Financial Statements from the effective date of acquisition or up to the date of disposal.
Revenue Recognition
Our revenues are generated principally from the sale of our products. Revenue from the sale of products is recognized at the time title and the risks and rewards of ownership pass to the customer. This generally occurs when the products reach the shipping point, the sales price is fixed and determinable, and collection is reasonably assured.
We generally warrant that our products will conform to our, or mutually agreed to, specifications and that our products will be free from material defects in materials and workmanship for a limited time. We limit our warranty to the replacement or repair of defective parts, or a refund or credit of the price of the defective product. We accept returned goods only when the customer makes a verified claim and we have authorized the return. Generally, a reserve for estimated returns is established at the time of sale based on historical return experience and is recorded as a reduction of sales.
We provide certain distributors with an inventory allowance for returns or scrap equal to a percentage of qualified purchases. A reserve for estimated returns and scrap allowances is established at the time of the sale based on an agreed-upon, fixed percentage of sales to distributors and is recorded as a reduction of sales.
Other allowances include customer quantity and price discrepancies. A reserve for other allowances is generally established at the time of sale based on historical experience and is recorded as a reduction of sales. We believe we can reasonably and reliably estimate the amounts of future allowances.
See "Recently Issued Accounting Pronouncements" below for information regarding our adoption of Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers , in fiscal 2019.
Inventories
Inventories are recorded at the lower of cost or net realizable value using the first-in, first-out cost method.
Property, Plant, and Equipment, Net
Property, plant, and equipment is recorded at cost less accumulated depreciation. Maintenance and repair expenditures are charged to expense when incurred. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, which are 10 to 20 years for land improvements, 5 to 40 years for buildings and improvements, and 1 to 15 years for machinery and equipment.
We periodically evaluate, when events and circumstances warrant, the net realizable value of property, plant, and equipment and other long-lived assets, relying on a number of factors including operating results, business plans, economic projections, and anticipated future cash flows. When indicators of potential impairment are present, the carrying values of the asset group are evaluated in relation to the operating performance and estimated future undiscounted cash flows of the underlying asset group. Impairment of the carrying value is recognized whenever anticipated future undiscounted cash flow estimates are less than the carrying value of the asset. Fair value estimates are based on assumptions concerning the amount and timing of estimated future cash flows and discount rates, reflecting varying degrees of perceived risk.
Goodwill and Other Intangible Assets
Intangible assets include both indeterminable-lived residual goodwill and determinable-lived identifiable intangible assets. Intangible assets with determinable lives primarily include intellectual property, consisting of patents, trademarks, and unpatented technology, and customer relationships. Recoverability estimates range from 1 to 50 years and costs are generally amortized on a straight-line basis. Evaluations of the remaining useful lives of determinable-lived intangible assets are performed on a periodic basis and when events and circumstances warrant.
At fiscal year end 2018, we had five reporting units, all of which contained goodwill. There were two reporting units in both the Transportation Solutions and Industrial Solutions segments and one reporting unit in the Communications Solutions segment. When changes occur in the composition of one or more reporting units, goodwill is reassigned to the reporting units affected based on their relative fair values.
Goodwill impairment is evaluated by comparing the carrying value of each reporting unit to its fair value on the first day of the fourth fiscal quarter of each year or whenever we believe a triggering event requiring a more frequent assessment has occurred. In assessing the existence of a triggering event, management relies on a number of reporting unit-specific factors including operating results, business plans, economic projections, anticipated future cash flows, transactions, and market place data. There are inherent uncertainties related to these factors and management's judgment in applying these factors to the impairment analysis.
When testing for goodwill impairment, we perform a step I goodwill impairment test to identify potential impairment by comparing the fair value of a reporting unit with its carrying amount. If the carrying amount of a reporting unit exceeds its fair value, goodwill may be impaired and a step II goodwill impairment test is performed to measure the amount of impairment, if any. In the step II goodwill impairment test, we compare the implied fair value of reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to the excess. The implied fair value of goodwill is determined in a manner consistent with how goodwill is recognized in a business combination. We allocate the fair value of a reporting unit to the assets and liabilities of that unit, including intangible assets, as if the reporting unit had been acquired in a business combination. Any excess of the fair value of a reporting unit over the amounts assigned to its assets and liabilities is the implied fair value of goodwill.
Fair value estimates used in the step I goodwill impairment tests are calculated using an income approach based on the present value of future cash flows of each reporting unit. The income approach has been supported by guideline analyses (a market approach). These approaches incorporate a number of assumptions including future growth rates, discount rates, income tax rates, and market activity in assessing fair value and are reporting unit specific. Changes in economic and operating conditions impacting these assumptions could result in goodwill impairments in future periods.
Research and Development
Research and development expenditures are expensed when incurred and are included in research, development, and engineering expenses on the Consolidated Statements of Operations. Research and development expenses include salaries, direct costs incurred, and building and overhead expenses. The amounts expensed in fiscal 2018, 2017, and 2016 were $606 million, $548 million, and $525 million, respectively.
Income Taxes
Income taxes are computed in accordance with the provisions of ASC 740, Income Taxes . Deferred tax liabilities and assets are recognized for the expected future tax consequences of events that have been reflected on the Consolidated Financial Statements. Deferred tax liabilities and assets are determined based on the differences between the book and tax bases of particular assets and liabilities and operating loss carryforwards using tax rates in effect for the years in which the differences are expected to reverse. A valuation allowance is provided to offset deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.
The calculation of our tax liabilities includes estimates for uncertainties in the application of complex tax regulations across multiple global jurisdictions where we conduct our operations. Under the uncertain tax position provisions of ASC 740, we recognize liabilities for tax and related interest for issues in tax jurisdictions based on our estimate of whether, and the extent to which, additional taxes and related interest will be due. These tax liabilities and related interest are reflected net of the impact of related tax loss carryforwards, as such tax loss carryforwards will be applied against these tax liabilities and will reduce the amount of cash tax payments due upon the eventual settlement with the tax authorities. These estimates may change due to changing facts and circumstances. Due to the complexity of these uncertainties, the ultimate resolution may result in a settlement that differs from our current estimate of the tax liabilities and related interest.
Financial Instruments
Our financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, debt, and derivative financial instruments.
We account for derivative financial instrument contracts on the Consolidated Balance Sheets at fair value. For instruments not designated as hedges under ASC 815, Derivatives and Hedging , the changes in the instruments' fair value are recognized currently in earnings. For instruments designated as cash flow hedges, the effective portion of changes in the fair value of a derivative is recorded in other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the underlying hedged item affects earnings. Ineffective portions of a cash flow hedge, including amounts excluded from the hedging relationship, are recognized currently in earnings. Changes in the fair value of instruments designated as fair value hedges affect the carrying value of the asset or liability hedged, with changes in both the derivative instrument and the hedged asset or liability being recognized currently in earnings.
We determine the fair value of our financial instruments by using methods and assumptions that are based on market conditions and risks existing at each balance sheet date. Standard market conventions are used to determine the fair value of financial instruments, including derivatives.
The cash flows related to derivative financial instruments are reported in the operating activities section of the Consolidated Statements of Cash Flows.
Our derivative financial instruments present certain market and counterparty risks. Concentration of counterparty risk is mitigated, however, by our use of financial institutions worldwide, substantially all of which have long-term Standard & Poor's, Moody's, and/or Fitch credit ratings of A/A2 or higher. In addition, we utilize only conventional derivative financial instruments. We are exposed to potential losses if a counterparty fails to perform according to the terms of its agreement. With respect to counterparty net asset positions recognized at fiscal year end 2018, we have assessed the likelihood of counterparty default as remote. We currently provide guarantees from a wholly-owned subsidiary to the counterparties to our commodity swap derivatives and exchange cash collateral with the counterparties to our cross-currency swap contracts. The likelihood of performance on the guarantees has been assessed as remote. For all other derivative financial instruments, we are not required to provide, nor do we require counterparties to provide, collateral or other security.
Fair Value Measurements
ASC 820, Fair Value Measurements and Disclosures , specifies a fair value hierarchy based upon the observable inputs utilized in valuation of certain assets and liabilities. Observable inputs (highest level) reflect market data obtained from independent sources, while unobservable inputs (lowest level) reflect internally developed market assumptions. Fair value measurements are classified under the following hierarchy:
•
Level 1. Quoted prices in active markets for identical assets and liabilities.
•
Level 2. Quoted prices in active markets for similar assets and liabilities, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.
•
Level 3. Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flows methodologies, and similar techniques that use significant unobservable inputs.
Derivative financial instruments measured at fair value on a recurring basis are generally valued using level 2 inputs.
Financial instruments other than derivative instruments include cash and cash equivalents, accounts receivable, accounts payable, and debt. These instruments are recorded on the Consolidated Balance Sheets at book value. For cash and cash equivalents, accounts receivable, and accounts payable, we believe book value approximates fair value due to the short-term nature of these instruments. See Note 11 for disclosure of the fair value of debt. The following is a description of the valuation methodologies used for the respective financial instruments:
•
Cash and cash equivalents. Cash and cash equivalents are valued at book value, which we consider to be equivalent to unadjusted quoted prices (level 1).
•
Accounts receivable. Accounts receivable are valued based on the net value expected to be realized. The net realizable value generally represents an observable contractual agreement (level 2).
•
Accounts payable. Accounts payable are valued based on the net value expected to be paid, generally supported by an observable contractual agreement (level 2).
•
Debt. The fair value of debt, including both current and non-current maturities, is derived from quoted market prices or other pricing determinations based on the results of market approach valuation models using observable market data such as recently reported trades, bid and offer information, and benchmark securities (level 2).
Pension Liabilities
The funded status of our defined benefit pension plans is recognized on the Consolidated Balance Sheets and is measured as the difference between the fair value of plan assets and the projected benefit obligation at the measurement date. The projected benefit obligation represents the actuarial present value of benefits projected to be paid upon retirement factoring in estimated future compensation levels. The fair value of plan assets represents the current market value of cumulative company and participant contributions made to irrevocable trust funds, held for the sole benefit of participants, which are invested by the trustee of the funds. The benefits under our defined benefit pension plans are based on various factors, such as years of service and compensation.
Net periodic pension benefit cost is based on the utilization of the projected unit credit method of calculation and is charged to earnings on a systematic basis over the expected average remaining service lives of current participants.
The measurement of benefit obligations and net periodic benefit cost is based on estimates and assumptions determined by our management. These valuations reflect the terms of the plans and use participant-specific information such as compensation, age, and years of service, as well as certain assumptions, including estimates of discount rates, expected return on plan assets, rate of compensation increases, interest crediting rates, and mortality rates.
Share-Based Compensation
We determine the fair value of share awards on the date of grant. Share options are valued using the Black-Scholes-Merton valuation model; restricted share awards and performance awards are valued using our end-of-day share price on the date of grant. The fair value is expensed ratably over the expected service period, with an allowance made for estimated forfeitures based on historical employee activity. Estimates regarding the attainment of performance criteria are reviewed periodically; the cumulative impact of a change in estimate regarding the attainment of performance criteria is recorded in the period in which that change is made.
Earnings Per Share
Basic earnings per share is computed by dividing net income by the basic weighted-average number of common shares outstanding. Diluted earnings per share is computed by dividing net income by the weighted-average number of common shares outstanding adjusted for the potentially dilutive impact of share-based compensation arrangements.
Currency Translation
For our non-U.S. dollar functional currency subsidiaries, assets and liabilities are translated into U.S. dollars using fiscal year end exchange rates. Sales and expenses are translated at average monthly exchange rates. Foreign currency translation gains and losses are included as a component of accumulated other comprehensive income (loss) within equity.
Gains and losses resulting from foreign currency transactions, which are included in earnings, were immaterial in fiscal 2018, 2017, and 2016.
Restructuring Charges
Restructuring activities involve employee-related termination costs, facility exit costs, and asset impairments resulting from reductions-in-force, migration of facilities or product lines from higher-cost to lower-cost countries, or consolidation of facilities within countries. We recognize termination costs based on requirements established by severance policy, government law, or previous actions. Facility exit costs generally reflect the cost to terminate a facility lease before the end of its term (measured at fair value at the time we cease using the facility) or costs that will continue to be incurred under the facility lease without future economic benefit to us. Restructuring activities often result in the disposal or abandonment of assets that require an acceleration of depreciation or impairment reflecting the excess of the assets' carrying values over fair value.
The recognition of restructuring costs require that we make certain judgments and estimates regarding the nature, timing, and amount of costs associated with the planned exit activity. To the extent our actual results differ from our estimates and assumptions, we may be required to revise the estimated liabilities, requiring the recognition of additional restructuring costs or the reduction of liabilities already recognized. At the end of each reporting period, we evaluate the remaining accrued balances to ensure these balances are properly stated and the utilization of the reserves are for their intended purpose in accordance with developed exit plans.
Contingent Liabilities
We record a loss contingency when the available information indicates it is probable that we have incurred a liability and the amount of the loss is reasonably estimable. When a range of possible losses with equal likelihood exists, we record the low end of the range. The likelihood of a loss with respect to a particular contingency is often difficult to predict, and determining a meaningful estimate of the loss or a range of loss may not be practicable based on information available. In addition, it is not uncommon for such matters to be resolved over many years, during which time relevant developments and new information must continuously be evaluated to determine whether a loss is probable and a reasonable estimate of that loss can be made. When a loss is probable but a reasonable estimate cannot be made, or when a loss is at least reasonably possible, disclosure is provided.
Recently Issued Accounting Pronouncements
In October 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-16, an update to ASC 740, Income Taxes . This new guidance requires the recognition of the income tax consequences of intra-entity transfers of assets other than inventory in the period in which the transfer occurs. The update, which we will adopt on a modified retrospective basis, is effective for us in the first quarter of fiscal 2019. Adoption is expected to result in a $443 million cumulative-effect adjustment to beginning accumulated earnings, which represents the net reversal of all balances associated with deferred tax impacts of intra-entity transfers of assets other than inventory. This will result in a decrease in other assets of $798 million, an increase in deferred tax assets of $418 million, and a decrease in prepaid expenses and other current assets of $63 million on the Consolidated Balance Sheet.
In February 2016, the FASB issued ASU No. 2016-02 which codified ASC 842, Leases . This guidance, as subsequently amended, requires lessees to recognize a lease liability and a right-of-use asset for most leases and is effective for us in the first quarter of fiscal 2020. We are currently in the process of updating policies, internal controls, financial statement disclosures, and systems to incorporate the impact of the new standard in our financial reporting processes. We intend to adopt the standard using the modified retrospective approach in the period of adoption, as permitted by ASU No. 2018-11. We expect that adoption will likely have a material impact to our Consolidated Balance Sheet; however, we currently do not expect adoption to have a material impact to our results of operations or cash flows. We believe that we are following an appropriate timeline to adopt the new standard in the first quarter of fiscal 2020.
In May 2014, the FASB issued ASU No. 2014-09 which codified ASC 606, Revenue from Contracts with Customers . This guidance supersedes ASC 605, Revenue Recognition , and introduces a single, comprehensive, five-step revenue recognition model. ASC 606 also enhances disclosures related to revenue recognition. ASC 606, as amended, is effective for us beginning in fiscal 2019. Significantly all our revenues are generated from the sale of products. Our Subsea Communications ("SubCom") business, which is reported in discontinued operations, generates contract revenues for construction related projects which are recorded primarily using the percentage-of-completion method. Our review of existing contracts, which is complete, affirms that product revenue and contract revenue will continue to be recognized at a point in time and over-time, respectively, in a manner consistent with current practice. See Notes 4 and 23 for additional information regarding our SubCom business. In fiscal 2018, we completed the process of updating policies, internal controls, financial statement disclosures, and systems to incorporate the impact of the new standard in our financial reporting processes. We will adopt the new standard using the modified retrospective approach and have determined that transition impacts, which relate primarily to incentive compensation arrangements, are not material to our results of operations or financial position.
Recently Adopted Accounting Pronouncements
In February 2018, the FASB issued ASU No. 2018-02, an update to ASC 220, Income Statement—Reporting Comprehensive Income , to allow a reclassification from accumulated other comprehensive income (loss) for stranded tax effects resulting from the Tax Cuts and Jobs Act (the "Act"). See Note 15 for additional information regarding the Act. We elected to early adopt this update in fiscal 2018 and reclassify the stranded tax effects resulting from the change in the U.S. federal corporate income tax rate. This change in accounting principle resulted in a reclassification of $38 million, primarily associated with our pension plans, during the period of adoption. The reclassification increased both accumulated other comprehensive loss and accumulated earnings on the Consolidated Balance Sheet with no impact to total shareholders' equity.
In March 2017, the FASB issued ASU No. 2017-07, an update to ASC 715, Compensation—Retirement Benefits, which changes the income statement presentation of net periodic pension and postretirement benefit costs. The ASU requires that service costs be presented with other employee compensation costs within operating income and that other cost components be presented outside of operating income. We elected to early adopt this update in fiscal 2018. The update was applied retrospectively and did not have a material impact on our Consolidated Statements of Operations.
In March 2016, the FASB issued ASU No. 2016-09, an update to ASC 718, Compensation—Stock Compensation , to simplify various aspects of accounting for share-based payments to employees. We elected to early adopt this update in fiscal 2017. The provisions of the update addressing the accounting for excess tax benefits and deficiencies were adopted using a modified retrospective transition approach, with a cumulative-effect adjustment to beginning accumulated earnings and a corresponding increase in deferred tax assets of $165 million. The provision of the update addressing the presentation on the statement of cash flows of employee taxes paid via the withholding of shares was applied retrospectively and did not have a material impact on our Consolidated Financial Statements. Adoption of other provisions, which were applied prospectively, also did not have a material impact on our Consolidated Financial Statements. |
