SUMMARY OF ACCOUNTING POLICIES
SUMMARY OF ACCOUNTING POLICIES
Basis of Financial Statements and Business Activities
The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), and include the accounts of United Parcel Service, Inc., and all of its consolidated subsidiaries (collectively “UPS” or the “Company”). All intercompany balances and transactions have been eliminated.
UPS concentrates its operations in the field of transportation services, primarily domestic and international letter and package delivery. Through our Supply Chain & Freight subsidiaries, we are also a global provider of specialized transportation, logistics and financial services.
Use of Estimates
The preparation of our consolidated financial statements requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, the reported amounts of revenues and expenses and the disclosure of contingencies. Estimates have been prepared on the basis of the most current and best information, and actual results could differ materially from those estimates.
Revenue Recognition
U.S. Domestic and International Package Operations—Revenue is recognized upon delivery of a letter or package.
Forwarding and Logistics—Freight forwarding revenue and the expense related to the transportation of freight are recognized at the time the services are completed. Truckload freight brokerage revenue and related transportation costs are recognized upon delivery of the shipment by a third-party carrier. Logistics and distribution revenue is recognized upon performance of the service provided. Customs brokerage revenue is recognized upon completing documents necessary for customs entry purposes.
UPS Freight—Revenue is recognized upon delivery of a less-than-truckload (“LTL”) or truckload (“TL”) shipment.
In our transportation businesses, we utilize independent contractors and third-party carriers in the performance of some transportation services. In situations where we act as principal party to the transaction, we recognize revenue on a gross basis; in circumstances where we act as an agent, we recognize revenue net of the cost of the purchased transportation.
Financial Services—Income on loans and direct finance leases is recognized on the effective interest method. Accrual of interest income is suspended at the earlier of the time at which collection of an account becomes doubtful or the account becomes 90 days delinquent. Income on operating leases is recognized on the straight-line method over the terms of the underlying leases.
Cash and Cash Equivalents
Cash and cash equivalents consist of highly liquid investments that are readily convertible into cash. We consider securities with maturities of three months or less, when purchased, to be cash equivalents. The carrying amount of these securities approximates fair value because of the short-term maturity of these instruments.

Investments
Marketable securities are either classified as trading or available-for-sale securities and are carried at fair value. Unrealized gains and losses on trading securities are reported as investment income and other on the statements of consolidated income. Unrealized gains and losses on available-for-sale securities are reported as accumulated other comprehensive income (“AOCI”), a separate component of shareowners’ equity. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion is included in investment income and other, along with interest and dividends. The cost of securities sold is based on the specific identification method; realized gains and losses resulting from such sales are included in investment income and other.
We periodically review our available-for-sale investments for indications of other-than-temporary impairment considering many factors, including the extent and duration to which a security’s fair value has been less than its cost, overall economic and market conditions and the financial condition and specific prospects for the issuer. Impairment of available-for-sale securities results in a charge to income when a market decline below cost is other-than-temporary.
Accounts Receivable
Losses on accounts receivable are recognized when they are incurred, which requires us to make our best estimate of the probable losses inherent in our customer receivables at each balance sheet date. These estimates require consideration of historical loss experience, adjusted for current conditions, trends in customer payment frequency and judgments about the probable effects of relevant observable data, including present economic conditions and the financial health of specific customers and market sectors. Our risk management process includes standards and policies for reviewing major account exposures and concentrations of risk.
Our total allowance for doubtful accounts as of December 31, 2017 and 2016 was $104 and $102 million, respectively. Our total provision for doubtful accounts charged to expense during the years ended December 31, 2017, 2016 and 2015 was $133, $116 and $121 million, respectively.
Inventories
Fuel and other materials and supplies inventories are recognized as inventory when purchased, and then charged to expense when used in our operations. Jet fuel, diesel and unleaded gasoline inventories are valued at the lower of average cost or market. Total inventories were $404 and $342 million as of December 31, 2017 and 2016, respectively, and are included in “other current assets” on the consolidated balance sheets.
Property, Plant and Equipment
Property, plant and equipment are carried at cost. Depreciation and amortization are provided by the straight-line method over the estimated useful lives of the assets, which are as follows: Vehicles—3 to 15 years; Aircraft—12 to 30 years; Buildings—20 to 40 years; Leasehold Improvements—lesser of asset useful life or lease term; Plant Equipment—3 to 20 years; Technology Equipment—3 to 5 years. The costs of major airframe and engine overhauls, as well as routine maintenance and repairs, are charged to expense as incurred.
Interest incurred during the construction period of certain property, plant and equipment is capitalized until the underlying assets are placed in service, at which time amortization of the capitalized interest begins, straight-line, over the estimated useful lives of the related assets. Capitalized interest was $49, $14 and $13 million for 2017, 2016, and 2015, respectively.
We review long-lived assets for impairment when circumstances indicate the carrying amount of an asset may not be recoverable based on the undiscounted future cash flows of the asset. If the carrying amount of the asset is determined not to be recoverable, a write-down to fair value is recorded. Fair values are determined based on quoted market values, discounted cash flows, or external appraisals, as appropriate. We review long-lived assets for impairment at the individual asset or the asset group level for which the lowest level of independent cash flows can be identified.
Goodwill and Intangible Assets
Costs of purchased businesses in excess of net identifiable assets acquired (goodwill), and indefinite-lived intangible assets are tested for impairment at least annually, unless changes in circumstances indicate an impairment may have occurred sooner. We are required to test goodwill on a “reporting unit” basis. A reporting unit is the operating segment unless, for businesses within that operating segment, discrete financial information is prepared and regularly reviewed by management, in which case such a component business is the reporting unit.
During the third quarter of 2017, we changed the measurement date of our annual goodwill impairment test from October 1st to July 1st. This change better aligns the timing of the goodwill impairment test with our long-term business planning process. The change was not material to our consolidated financial statements as it did not result in the delay, acceleration or avoidance of an impairment charge.
In assessing goodwill for impairment, we initially evaluate qualitative factors to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. We consider several factors, including macroeconomic conditions, industry and market conditions, overall financial performance of the reporting unit, changes in management, strategy or customers and relevant reporting unit-specific events such as a change in the carrying amount of net assets, a more likely than not expectation of selling or disposing all, or a portion, of a reporting unit, and the testing for recoverability of a significant asset group within a reporting unit. If this qualitative assessment results in a conclusion that it is more likely than not that the fair value of a reporting unit exceeds the carrying value, then no further testing is performed for that reporting unit.
If the qualitative assessment is not conclusive and it is necessary to calculate the fair value of a reporting unit, then we utilize a two-step process to test goodwill for impairment. First, a comparison of the fair value of the applicable reporting unit with the aggregate carrying value, including goodwill, is performed. If the carrying amount of a reporting unit exceeds its calculated fair value, then the second step is performed, and an impairment charge is recognized for the amount, if any, by which the carrying amount of goodwill exceeds its implied fair value. We primarily determine the fair value of our reporting units using a discounted cash flow model and supplement this with observable valuation multiples for comparable companies, as appropriate.
A trade name with a carrying value of $200 million and licenses with a carrying value of $5 million as of December 31, 2017 are considered to be indefinite-lived intangibles, and therefore are not amortized. Indefinite-lived intangible assets are reviewed for impairment at least annually. We determined that the income approach, specifically the relief from royalty method, is the most appropriate valuation method to estimate the fair value of the trade name. The estimated fair value of the trade name is compared to the carrying value of the asset. If the carrying value of the trade name exceeds its estimated fair value, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds its fair value.
Finite-lived intangible assets, including trademarks, licenses, patents, customer lists, non-compete agreements and franchise rights are amortized on a straight-line basis over the estimated useful lives of the assets, which range from 2 to 22 years. Capitalized software is generally amortized over 7 years.
Self-Insurance Accruals
We self-insure costs associated with workers’ compensation claims, automotive liability, health and welfare and general business liabilities, up to certain limits. Insurance reserves are established for estimates of the loss that we will ultimately incur on reported claims, as well as estimates of claims that have been incurred but not yet reported. Recorded balances are based on reserve levels, which incorporate historical loss experience and judgments about the present and expected levels of cost per claim. Trends in actual experience are a significant factor in the determination of such reserves.
Workers’ compensation, automobile liability and general liability insurance claims may take several years to completely settle. Consequently, actuarial estimates are required to project the ultimate cost that will be incurred to fully resolve the claims. A number of factors can affect the actual cost of a claim, including the length of time the claim remains open, trends in healthcare costs and the results of related litigation. Furthermore, claims may emerge in future years for events that occurred in a prior year at a rate that differs from previous actuarial projections. Changes in state legislation with respect to workers' compensation can affect the adequacy of our self-insurance accruals. All of these factors can result in revisions to prior actuarial projections and produce a material difference between estimated and actual operating results. Prior to 2017, outside actuarial studies were performed semi-annually and we used the studies to estimate the liability in intervening quarters. Beginning in 2017, outside actuarial studies are now performed quarterly as we believe this provides us with better quarterly estimates of our outstanding workers' compensation liability.
We sponsor a number of health and welfare insurance plans for our employees. These liabilities and related expenses are based on estimates of the number of employees and eligible dependents covered under the plans, anticipated medical usage by participants and overall trends in medical costs and inflation.
Pension and Postretirement Benefits
We incur certain employment-related expenses associated with pension and postretirement medical benefits. These pension and postretirement medical benefit costs for company-sponsored benefit plans are calculated using various actuarial assumptions and methodologies, including discount rates, expected returns on plan assets, healthcare cost trend rates, inflation, compensation increase rates, mortality rates and coordination of benefits with plans not sponsored by UPS. Actuarial assumptions are reviewed on an annual basis, unless circumstances require an interim remeasurement for any of our plans.

We recognize changes in the fair value of plan assets and net actuarial gains or losses in excess of a corridor (defined as 10% of the greater of the fair value of plan assets or the plans' projected benefit obligations) in pension expense annually at December 31st each year. The remaining components of pension expense, primarily service and interest costs and the expected return on plan assets, are recorded on a quarterly basis.
Effective July 1, 2016, the UPS Retirement Plan was closed to new non-union participants. For eligible employees hired after July 1, 2016, UPS contributes annually to a defined contribution plan. We recognize expense for the required contribution quarterly, and we recognize a liability for any contributions due and unpaid (included in “other current liabilities”).
During June 2017, we amended the UPS Retirement Plan and Excess Coordinating Plans to cease accrual of additional benefits for future service for non-union participants effective January 1, 2023. We remeasured plan assets and pension benefit obligations compensation for the affected pension plans as of June 30, 2017 to recognize the impact of this change.
We participate in a number of trustee-managed multiemployer pension and health and welfare plans for employees covered under collective bargaining agreements. Our contributions to these plans are determined in accordance with the respective collective bargaining agreements. We recognize expense for the contractually required contribution for each period, and we recognize a liability for any contributions due and unpaid (included in “other current liabilities”).
Income Taxes
Income taxes are accounted for on an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our consolidated financial statements or tax returns. In estimating future tax consequences, we generally consider all expected future events other than proposed changes in the tax law or rates. Valuation allowances are provided if it is more likely than not that a deferred tax asset will not be realized.
We recognize liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. Once it is determined that the position meets the recognition threshold, the second step requires us to estimate and measure the largest amount of tax benefit that is more likely than not to be realized upon ultimate settlement. The difference between the amount of recognizable tax benefit and the total amount of tax benefit from positions filed or to be filed with the tax authorities is recorded as a liability for uncertain tax benefits. It is inherently difficult and subjective to estimate such amounts, as we have to determine the probability of various possible outcomes. We reevaluate uncertain tax positions on a quarterly basis. This evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit atctivity. Such a change in recognition or measurement could result in the recognition of a tax benefit or an additional charge to the tax provision.
In January 2018, the FASB released guidance on the accounting for tax on the global intangible low-taxed income ("GILTI") provisions of the Tax Cuts and Jobs Act (the "Tax Act"). The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The guidance indicates that either accounting for deferred taxes related to GILTI inclusions or treating any taxes on GILTI inclusions as period costs are both acceptable methods subject to an accounting policy election. We elect to treat any potential GILTI inclusions as period costs.
Foreign Currency Translation and Remeasurement
We translate the results of operations of our foreign subsidiaries using average exchange rates during each period, whereas balance sheet accounts are translated using exchange rates at the end of each period. Balance sheet currency translation adjustments are recorded in AOCI. Pre-tax foreign currency transaction gains from remeasurement, net of hedging, included in other operating expenses, investment income and interest expense were $3, $5 and $7 million in 2017, 2016 and 2015, respectively.
Stock-Based Compensation
All share-based awards to employees are measured based on their fair values and expensed over the period during which an employee is required to provide service in exchange for the award (the vesting period), less estimated forfeitures. We issue employee share-based awards under the UPS Incentive Compensation Plan that are subject to specific vesting conditions; including service conditions, where the awards cliff vest or vest ratably over a three or five year period (the "nominal vesting period”) or at the date the employee retires (as defined by the plan), if earlier. Compensation cost is generally recognized immediately for awards granted to retirement-eligible employees, or over the period from the grant date to the date retirement eligibility is achieved, if that is expected to occur during the nominal vesting period. We estimate forfeiture rates based on historical rates of forfeitures for awards with similar characteristics, historical rates of employee turnover and the nature and terms of the vesting conditions of the awards. We reevaluate our forfeiture rates on an annual basis.
Fair Value Measurements
Our financial assets and liabilities measured at fair value on a recurring basis have been categorized based upon a fair value hierarchy. Level 1 inputs utilize quoted prices in active markets for identical assets or liabilities. Level 2 inputs are based on other observable market data, such as quoted prices for similar assets and liabilities, and inputs other than quoted prices that are observable, such as interest rates and yield curves. Level 3 inputs are developed from unobservable data reflecting our own assumptions, and include situations where there is little or no market activity for the asset or liability.
Certain non-financial assets and liabilities are measured at fair value on a nonrecurring basis, including property, plant, and equipment, goodwill and intangible assets. These assets are not measured at fair value on a recurring basis; however, they are subject to fair value adjustments in certain circumstances, such as when there is evidence of an impairment. A general description of the valuation methodologies used for assets and liabilities measured at fair value, including the general classification of such assets and liabilities pursuant to the valuation hierarchy, is included in each footnote with fair value measurements present.

We allocate the fair value of purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired based on their estimated fair values. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired customers, acquired technology and trade names from a market participant perspective, useful lives and discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, which is one year from the acquisition date, we may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings.
Derivative Instruments
All financial derivative instruments are recorded on our consolidated balance sheets at fair value. Derivatives not designated as hedges must be adjusted to fair value through income. If a derivative is designated as a hedge, changes in its fair value that are considered to be effective, as defined, either (depending on the nature of the hedge) offset the change in fair value of the hedged assets, liabilities or firm commitments through income, or are recorded in AOCI until the hedged item is recorded in income. Any portion of a change in a hedge’s fair value that is considered to be ineffective, or is excluded from the measurement of effectiveness, is recorded immediately in income.
Adoption of New Accounting Standards
In March 2016, the Financial Accounting Standards Board ("FASB") issued an accounting standards update that simplifies the income tax accounting and cash flow presentation related to share-based compensation by requiring the recognition of all excess tax benefits and deficiencies directly on the income statement and classification as cash flows from operating activities on the statement of cash flows. This new guidance became effective for us in the first quarter of 2017 and we adopted the statements of consolidated cash flows presentation on a prospective basis. The impact to income tax expense in 2017 in the statements of consolidated income was a benefit of $71 million. Additionally, we have elected to continue estimating forfeitures expected to occur to determine the amount of compensation cost to be recognized each period.
In September 2015, the FASB issued an accounting standards update that simplifies the accounting for measurement-period adjustments related to business combinations. This update removes the requirement to retrospectively apply adjustments made to estimated amounts recognized in a business combination. This update permits the purchaser to adjust the estimated amounts in the reporting period in which the adjustment amounts are determined. This new guidance would have become effective for us in the first quarter of 2016; however, we elected to early adopt this standard in the third quarter of 2015. This accounting standards update did not have a material impact on our consolidated financial position or results of operations.
Accounting Standards Issued But Not Yet Effective
In February 2018, the FASB issued an accounting standards update that allows a reclassification from AOCI to retained earnings for stranded tax effects resulting from the Tax Act.  The guidance will generally be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act is recognized. The update becomes effective for us in the first quarter of 2019, but early adoption is permitted. We are currently evaluating this update to determine the full impact of its adoption.
In August 2017, the FASB issued an accounting standards update to enhance recognition of the economic results of hedging activities in the financial statements. In addition, this update makes certain targeted improvements to simplify the application of the hedge accounting guidance and increase transparency regarding the scope and results of hedging activities. The guidance will generally be applied prospectively and becomes effective for us in the first quarter of 2019, but early adoption is permitted. We are currently evaluating this update to determine the full impact of its adoption but do not expect this accounting standards update to have a material impact on our consolidated financial position, results of operations or cash flows.
In May 2017, the FASB issued an accounting standards update to provide clarity and reduce complexity on when to apply modification accounting to existing share-based payment awards. The guidance will be applied prospectively. We adopted this standard on January 1, 2018. This accounting standards update does not have a material impact on our consolidated financial position, results of operations or cash flows.
In March 2017, the FASB issued an accounting standards update to require the premium on callable debt securities to be amortized to the earliest call date. The amortization period for callable debt securities purchased at a discount would not be impacted by the proposed update. Under current GAAP, premiums on callable debt securities are generally amortized over the contractual life of the security. Only in cases when an entity has a large number of similar securities is it allowed to consider estimates of principal prepayments. Amortization of the premium over the contractual life of the instrument can result in losses being recorded for the unamortized premium if the issuer exercises the call feature prior to maturity. The standard will be effective for us in the first quarter of 2019, but early adoption is permitted. We are currently evaluating this update to determine the full impact of its adoption but do not expect this accounting standards update to have a material impact on our consolidated financial position, results of operations or cash flows.
In March 2017, the FASB issued an accounting standards update to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. The update requires employers to report the current service cost component in the same line item as other compensation costs arising from services rendered by employees during the period. The other components of net benefit cost are required to be presented separately from service cost and outside of income from operations. In accordance with the update, only the service cost component will be eligible for capitalization. The guidance in this update will be applied retrospectively for the presentation of service cost and other components of net benefit cost, and prospectively for the capitalization of the service cost component in assets. We adopted this standard on January 1, 2018. As a result of this update, the net amount of interest cost, prior service cost, expected return on plan assets and the actuarial gain (loss) in excess of the 10% corridor will be presented as other income (expense). For the years ended December 31, 2017, 2016 and 2015, non-service cost components amounted to an $11 million expense, a $2.236 billion expense, and a $420 million benefit, respectively, which were recognized in "Compensation and benefits" on the statements of consolidated income. After adoption, the non-service cost components will be recognized in "Other Income and (Expense)" on the statements of consolidated income.
In January 2017, the FASB issued an accounting standards update to simplify the accounting for goodwill impairment. The update removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The standard will be effective for us in the first quarter of 2020, but early adoption is permitted. We are currently evaluating this update to determine the full impact of its adoption but do not expect this accounting standards update to have a material impact on our consolidated financial position, results of operations or cash flows.
In November 2016, the FASB issued an accounting standards update that is intended to reduce diversity in practice by adding or clarifying guidance on classification and presentation of changes in restricted cash on the statement of cash flows. The guidance in this update will be applied retrospectively. We adopted this standard on January 1, 2018. As a result of this update, restricted cash will be included within cash and cash equivalents on our statements of consolidated cash flows. As of December 31, 2017 and 2016, we had $449 and $445 million, respectively, in investments and restricted cash primarily associated with our self-insurance requirements.
In August 2016, the FASB issued an accounting standards update that addresses the classification and presentation of specific cash flow issues that currently result in diverse practices. The guidance also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The guidance will be applied retrospectively. We adopted this standard on January 1, 2018. We have evaluated the impact of this standard on our statements of consolidated cash flows, and have determined that this standard does not have a material impact.
In February 2016, the FASB issued an accounting standards update that requires lessees to recognize a right-of-use asset and lease liability on the balance sheet for all leases with terms beyond twelve months. Although the distinction between operating and finance leases will continue to exist under the new standard, the recognition and measurement of expenses and cash flows will not change significantly from the current treatment. This new guidance requires modified retrospective application and becomes effective for us in the first quarter of 2019, but early adoption is permitted. We are currently evaluating this update to determine the full impact of its adoption on our consolidated financial position, results of operations, cash flows and related disclosures, as well as the impact of adoption on policies, practices and systems. As of December 31, 2017, we have $1.637 billion of future minimum operating lease commitments that are not currently recognized on our consolidated balance sheet (see note 8). Therefore, we expect material changes to our consolidated balance sheets.
In January 2016, the FASB issued an accounting standards update which addresses certain aspects of the recognition, measurement, presentation and disclosure of financial instruments. We adopted this standard on January 1, 2018. This accounting standards update does not have a material impact on our consolidated financial position, results of operations or cash flows.
In May 2014, the FASB issued an accounting standards update that changes the revenue recognition for companies that enter into contracts with customers to transfer goods or services. The standard is a comprehensive new revenue recognition model that requires revenue to be recognized in a manner depicting the transfer of goods or services to a customer at an amount that reflects the consideration expected to be received in exchange for those goods or services. The FASB has also issued a number of updates to this standard. We adopted the standard on January 1, 2018. Companies may use either a full retrospective or a modified retrospective approach to adopt this standard. We adopted the standard using a full retrospective approach.
We have determined that revenue recognition will be accelerated for the transportation businesses as the standard requires revenue to be recognized as control is transferred to the customer over time rather than upon delivery. We have determined that the impact of this change to the statements of consolidated income is not material.
The standard also requires us to evaluate whether our businesses promise to transfer services to the customer itself (as a principal) or to arrange for services to be provided by another party (as an agent). To make that determination, the standard uses a control model rather than the risks-and-rewards model in current GAAP. Based on our evaluation of the control model, we determined that certain Supply Chain & Freight businesses act as the principal rather than the agent within their revenue arrangements. This change will require the affected businesses to report transportation revenue gross of associated purchased transportation costs rather than net of such amounts within the statements of consolidated income. This change will result in reclassifications of approximately $709 and $720 million from contra-revenue to operating expenses on the statements of consolidated income for the periods ended December 31, 2017 and 2016, respectively.
In addition to completing our review of contracts and quantifying the impacts on the consolidated financial statements, we have analyzed our internal control over financial reporting framework and determined that there will be new controls added around contract inception and contract modifications, as well as periodic reviews of material contracts. In addition, we have reviewed the impacts of this standard on our footnote disclosures for periods subsequent to January 1, 2018. We have determined that the adoption of this standard will result in several additional disclosures, including but not limited to additional information around our performance obligations, the timing of revenue recognition, remaining performance obligations at period end, contract assets and liabilities and significant judgments made that impact the amount and timing of revenue from our contracts with customers.
