Comparability – Amounts within the consolidated balance sheet as of December 31, 2017 have been modified to conform to the current year presentation. Revenue in excess of billings is now presented separately. Previously, this amount was included in other current assets. Additionally, amounts within the cash flows from operating activities section of the consolidated statement of cash flows for the year ended December 31, 2017 have been modified to conform to the current year presentation. Gain on sales of businesses and customer lists is now presented separately. In the previous year, this amount was included within other non-cash items, net.

The consolidated statements of income for 2017 and 2016 have been revised to reflect the adoption of Accounting Standards Update (ASU) No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The consolidated statements of cash flows for 2017 and 2016 have been revised to reflect the adoption of ASU No. 2016-18, Restricted Cash. Further information regarding these standards can be found in Note 2.

Use of estimates – We have prepared the accompanying consolidated financial statements in conformity with generally accepted accounting principles (GAAP) in the United States. In this process, it is necessary for us to make certain assumptions and estimates affecting the amounts reported in the consolidated financial statements and related notes. These estimates and assumptions are developed based upon all available information. However, actual results can differ from assumed and estimated amounts.

Foreign currency translation – The financial statements of our foreign subsidiaries are measured in the respective subsidiaries' functional currencies, primarily Canadian and Australian dollars, and are translated into United States dollars. Assets and liabilities are translated using the exchange rates in effect at the balance sheet date. Revenue and expenses are translated at the average exchange rates during the year. The resulting translation gains and losses are reflected in accumulated other comprehensive loss in the shareholders' equity section of the consolidated balance sheets. Foreign currency transaction gains and losses are recorded in other income in the consolidated statements of income.

Cash and cash equivalents – We consider all cash on hand and other highly liquid investments with original maturities of 3 months or less to be cash and cash equivalents. The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents approximate fair value. Checks issued by us but not presented to the banks for payment may create negative book cash balances. These book overdrafts are included in accounts payable on the consolidated balance sheets and totaled $1,270 as of December 31, 2018 and $5,665 as of December 31, 2017.

Trade accounts receivable – Trade accounts receivable are initially recorded at the invoiced amount upon the sale of goods or services to customers, and they do not bear interest. They are stated net of allowances for uncollectible accounts, which represent estimated losses resulting from the inability of customers to make the required payments. When determining the allowances for uncollectible accounts, we take several factors into consideration, including the overall composition of accounts receivable aging, our prior history of accounts receivable write-offs, the type of customer and our day-to-day knowledge of specific customers. Changes in the allowances for uncollectible accounts are included in selling, general and administrative (SG&A) expense in our consolidated statements of income. The point at which uncollected accounts are written off varies by type of customer, but generally does not exceed 1 year from the due date of the receivable.

Funds held for customers – Our payroll services businesses collect funds from clients to pay their payroll and related taxes. We hold these funds temporarily until payments are remitted to the clients' employees and the appropriate taxing authorities. The customer contracts for our domestic payroll processing business include legal restrictions regarding the use of these funds. In addition, our treasury management cash receipt processing business remits a portion of cash receipts to our clients the business day following receipt. All of these funds, consisting of cash and available-for-sale debt securities, are reported as funds held for customers in the consolidated balance sheets. The corresponding liability for these obligations is included in accrued liabilities in the consolidated balance sheets. The available-for-sale debt securities are carried at fair value, with unrealized gains and losses included in accumulated other comprehensive loss in the consolidated balance sheets. Realized gains and losses are included in revenue in our consolidated statements of income and were not significant during the past 3 years.

Property, plant and equipment – Property, plant and equipment, including leasehold and other improvements that extend an asset's useful life or productive capabilities, are stated at historical cost less accumulated depreciation. Buildings have been assigned useful lives of 40 years and machinery and equipment are generally assigned useful lives ranging from 1 year to 11 years, with a weighted-average useful life of 7 years as of December 31, 2018. Buildings are depreciated using the 150% declining balance method, and machinery and equipment is depreciated using the sum-of-the-years' digits method. Leasehold and building improvements are depreciated on the straight-line basis over the estimated useful life of the property or the life of the lease, whichever is shorter. Maintenance and repairs are expensed as incurred.

Fully depreciated assets are retained in property, plant and equipment until disposal. Any gains or losses resulting from the disposition of property, plant and equipment are included in SG&A expense in the consolidated statements of income, with the exception of building sales. Such gains and losses are reported separately in the consolidated statements of income, if significant.

Assets held for sale – We record assets held for sale at the lower of their carrying value or fair value less costs to sell. Assets are classified as held for sale in our consolidated balance sheets when all of the following conditions are met: (1) management has the authority and commits to a plan to sell the assets; (2) the assets are available for immediate sale in their present condition; (3) there is an active program to locate a buyer and the plan to sell the assets has been initiated; (4) the sale of the assets is probable within one year; (5) the assets are being actively marketed at a reasonable sales price relative to their current fair value; and (6) it is unlikely that the plan to sell will be withdrawn or that significant changes to the plan will be made. Information regarding assets held for sale can be found in Note 3.

Intangibles – Intangible assets are stated at historical cost less accumulated amortization. Amortization expense is generally determined on the straight-line basis, with the exception of customer lists, which are generally amortized using accelerated methods that reflect the pattern in which we receive the economic benefit of the asset. Intangibles have been assigned useful lives ranging from 1 year to 14 years, with a weighted-average useful life of 6 years as of December 31, 2018. Each reporting period, we evaluate the remaining useful lives of our amortizable intangibles to determine whether events or circumstances warrant a revision to the remaining period of amortization. If our estimate of an asset's remaining useful life is revised, the remaining carrying amount of the asset is amortized prospectively over the revised remaining useful life. As of December 31, 2017, we held a trade name asset that was assigned an indefinite useful life. As such, this asset was not amortized, but was subject to impairment testing on at least an annual basis. During 2018, we determined that this asset was fully impaired. Further information regarding the resulting asset impairment charge can be found in Note 8. Any gains or losses resulting from the disposition of intangibles are included in SG&A expense in the consolidated statements of income.

We capitalize costs of software developed or obtained for internal use, including website development costs, once the preliminary project stage has been completed, management commits to funding the project and it is probable that the project will be completed and the software will be used to perform the function intended. Capitalized costs include only (1) external direct costs of materials and services consumed in developing or obtaining internal-use software, (2) payroll and payroll-related costs for employees who are directly associated with and who devote time to the internal-use software project, and (3) interest costs incurred, when significant, while developing internal-use software. Costs incurred in populating websites with information about the company or products are expensed as incurred. Capitalization of costs ceases when the project is substantially complete and ready for its intended use. The carrying value of internal-use software is reviewed in accordance with our policy on impairment of long-lived assets and amortizable intangibles.

We incur costs in connection with the development of certain software products that we sell to our customers. Costs for the development of software products to be sold are expensed as incurred until technological feasibility is established, at which time, such costs are capitalized until the product is available for general release to customers.

carrying amount may not be recoverable. Such circumstances could include, but are not limited to, (1) a significant decrease in the market value of an asset, (2) a significant adverse change in the extent or manner in which an asset is used or in its physical condition, or (3) an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of an asset. We compare the carrying amount of the asset group to the estimated undiscounted future cash flows associated with it. If the sum of the expected future net cash flows is less than the carrying value of the asset group being evaluated, an impairment loss would be recognized. The impairment loss would be calculated as the amount by which the carrying value of the asset group exceeds the fair value of the asset group. As quoted market prices are not available for the majority of our assets, the estimate of fair value is based on various valuation techniques, including the discounted value of estimated future cash flows. During 2018 and 2017, we recorded asset impairment charges related to certain intangible assets. Further information regarding these impairment charges can be found in Note 8.

We evaluate the recoverability of property, plant, equipment and intangibles held for sale by comparing the asset's carrying amount with its estimated fair value less costs to sell. Should the estimated fair value less costs to sell be less than the carrying value of the long-lived asset, an impairment loss would be recognized. The impairment loss would be calculated as the amount by which the carrying value of the asset exceeds the estimated fair value of the asset less costs to sell. During 2017, we recorded asset impairment charges related to Small Business Services assets held for sale. Further information regarding the impairment charges can be found in Note 8.

Impairment of indefinite-lived intangibles and goodwill – We evaluate the carrying value of indefinite-lived intangibles and goodwill on July 31^st of each year and between annual evaluations if events occur or circumstances change that would indicate a possible impairment. Such circumstances could include, but are not limited to, (1) a significant adverse change in legal factors or in business climate, (2) unanticipated competition, (3) an adverse change in market conditions that are indicative of a decline in the fair value of the assets, (4) a change in our business strategy, or (5) an adverse action or assessment by a regulator. Information regarding the results of our impairment analyses can be found in Note 8.

In completing the annual impairment analysis of our indefinite-lived trade name in each of the past 3 years, we elected to perform a quantitative assessment. This assessment compared the carrying amount of the asset to its estimated fair value. The estimate of fair value was based on the relief from royalty method, which calculates the cost savings associated with owning rather than licensing the trade name. An assumed royalty rate was applied to forecasted revenue and the resulting cash flows were discounted. If the estimated fair value is less than the carrying value of the asset, an impairment loss is recognized for the difference. During 2018, our analysis indicated that this asset was fully impaired. Further information regarding this impairment can be found in Note 8.

To analyze goodwill for impairment, we must assign our goodwill to individual reporting units. Identification of reporting units includes an analysis of the components that comprise each of our operating segments, which considers, among other things, the manner in which we operate our business and the availability of discrete financial information. Components of an operating segment are aggregated to form 1 reporting unit if the components have similar economic characteristics. We periodically review our reporting units to ensure that they continue to reflect the manner in which we operate our business.

When completing our annual goodwill impairment analysis, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after this qualitative assessment, we determine it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the quantitative impairment test is unnecessary.

When performing a quantitative analysis of goodwill, we calculate the estimated fair value of the reporting unit and compare this amount to the carrying amount of the reporting unit's net assets. In calculating the estimated fair value of a business unit, we use the income approach. This approach is a valuation technique under which we estimate future cash flows using the reporting unit's financial forecast from the perspective of an unrelated market participant. Using historical trending and internal forecasting techniques, we project revenue and apply our fixed and variable cost experience rates to the projected revenue to arrive at the future cash flows. A terminal value is then applied to the projected cash flow stream. Future estimated cash flows are discounted to their present value to calculate the estimated fair value. Our discount rate is the market-value-weighted average of our estimated cost of capital derived using both known and estimated customary market metrics. In determining the estimated fair values of our reporting units, we are required to estimate a number of factors, including projected operating results, terminal growth rates, economic conditions, anticipated future cash flows, the discount rate and the allocation of shared or corporate items. When completing a quantitative analysis for all of our reporting units, the summation of our reporting units' fair values is compared to our consolidated fair value, as indicated by our market capitalization, to evaluate the reasonableness of our calculations. If the carrying amount of a reporting unit's net assets exceeds its estimated fair value, an impairment loss is recorded for the difference, not to exceed the carrying amount of goodwill.

Prepaid product discounts – Certain of our financial institution contracts require prepaid product discounts in the form of upfront cash payments or accruals for amounts owed to financial institution clients of our Financial Services segment. These prepaid product discounts are included in other non-current assets in our consolidated balance sheets and are generally amortized as reductions of revenue on the straight-line basis over the contract term. Currently, these amounts are being amortized over periods ranging from 1 year to 10 years, with a weighted-average life of 6 years as of December 31, 2018. Whenever events or changes occur that impact the related contract, including significant declines in the anticipated profitability, we evaluate the carrying value of prepaid product discounts to determine if they are impaired. Should a financial institution cancel a contract prior to the agreement's termination date, or should the volume of orders realized through a financial institution fall below contractually-specified minimums, we generally have a contractual right to a refund of the remaining unamortized prepaid product discount.

Advertising costs – Deferred advertising costs include materials, printing, labor and postage costs related to direct response advertising programs of our Direct Checks and Small Business Services segments. These costs are amortized as SG&A expense over periods (not exceeding 18 months) that correspond to the estimated revenue streams of the individual advertisements. The actual revenue streams are analyzed at least annually to monitor the propriety of the amortization periods. Judgment is required in estimating the future revenue streams, especially with regard to check re-orders, which can span an extended period of time. Significant changes in the actual revenue streams would require the amortization periods to be modified, thus impacting our results of operations during the period in which the change occurred and in subsequent periods. Within our Direct Checks segment, approximately 88% of the costs of individual advertisements is expensed within 6 months of the advertisement. The deferred advertising costs of our Small Business Services segment are fully amortized within 6 months of the advertisement. Deferred advertising costs are included in other current assets and other non-current assets in the consolidated balance sheets.

Non-direct response advertising projects are expensed as incurred. Catalogs provided to financial institution clients of our Financial Services segment are accounted for as prepaid assets until they are shipped to financial institutions. The total amount of advertising expense, including direct response and non-direct response advertising, was $74,549 in 2018, $78,722 in 2017 and $85,141 in 2016.

Loans and notes receivable from distributors – We have, at times, provided loans to certain of our Safeguard^® distributors to allow them to purchase the operations of other small business distributors. We have also sold distributors and customer lists that we own in exchange for notes receivable. These loans and notes receivable are included in other current assets and other non-current assets in the consolidated balance sheets. Interest is accrued at market interest rates as earned. We continually monitor the credit quality and associated risks of these receivable on an individual basis based on criteria such as the financial stability of the distributor, historical commissions earned and their reported financial results. We generally withhold commissions payable to the distributors to settle the monthly payments due on the receivables, thus, somewhat mitigating the risk that the receivables will not be collected. As of December 31, 2018 and December 31, 2017, past due amounts, allowances for credit losses and receivables placed on non-accrual status were not significant. The determination to place receivables on non-accrual status or to resume the accrual of interest is completed on a case-by-case basis, evaluating the specifics of each situation.

Restructuring and integration expense – Over the past several years, we have recorded restructuring and integration expense as a result of various cost management efforts, including facility closings and the relocation of business activities, as well as fundamental changes in the manner in which certain business functions are conducted, including the integration of acquired businesses and the consolidation of redundant information technology systems. These expenses have consisted of costs which are expensed when incurred, such as information technology costs, employee and equipment moves, training and travel, as well as accruals for employee termination benefits payable under our ongoing severance benefit plan. We record accruals for employee termination benefits when it is probable that a liability has been incurred and the amount of the liability is reasonably estimable. We are required to make estimates and assumptions in calculating the restructuring accruals as, on some occasions, employees choose to voluntarily leave the company prior to their termination date or they secure another position within the company. In these situations, the employees do not receive termination benefits. To the extent our assumptions and estimates differ from our actual costs, subsequent adjustments to restructuring and integration accruals have been and will be required. Restructuring and integration accruals are included in accrued liabilities and other non-current liabilities in our consolidated balance sheets.

Litigation – We are party to legal actions and claims arising in the ordinary course of business. We record accruals for legal matters when the expected outcome of these matters is either known or considered probable and can be reasonably estimated. Our accruals do not include related legal and other costs expected to be incurred in defense of legal actions. Further information regarding litigation can be found in Note 16.

Income taxes – Deferred income taxes result from temporary differences between the financial reporting basis of assets and liabilities and their respective tax reporting basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences reverse. Net deferred tax assets are recognized to the extent that realization of such benefits is more likely than not.

We are subject to tax audits in numerous domestic and foreign tax jurisdictions. Tax audits are often complex and can require several years to complete. In the normal course of business, we are subject to challenges from the Internal Revenue Service and other tax authorities regarding the amount of taxes due. These challenges may alter the timing or amount of taxable income or deductions, or the allocation of income among tax jurisdictions. We recognize the benefits of tax return positions in the financial statements when they are more-likely-than-not to be sustained by the taxing authorities based solely on the technical merits of the position. If the recognition threshold is met, the tax benefit is measured and recognized as the largest amount of tax benefit that, in our judgment, is greater than 50% likely to be realized. Accrued interest and penalties related to unrecognized tax positions are included in our provision for income taxes in the consolidated statements of income.

We recognize all derivative financial instruments in the consolidated financial statements at fair value regardless of the purpose or intent for holding the instrument. Changes in the fair value of derivative financial instruments are recognized periodically either in income or in shareholders' equity as a component of accumulated other comprehensive loss, depending on whether the derivative financial instrument qualifies for hedge accounting, and if so, whether it qualifies as a fair value hedge or a cash flow hedge and whether the hedge is effective. Generally, changes in fair values of derivatives accounted for as fair value hedges are recorded in income along with the portion of the change in the fair value of the hedged items that relate to the hedged risk. Changes in fair values of derivatives accounted for as cash flow hedges, to the extent they are effective as hedges, are recorded in accumulated other comprehensive loss, net of tax. We classify the cash flows from derivative instruments that have been designated as fair value or cash flow hedges in the same category as the cash flows from the items being hedged. Changes in fair values of derivatives not qualifying as hedges and the ineffective portion of hedges are reported in income.

Revenue recognition – On January 1, 2018, we adopted ASU No. 2014-09, Revenue from Contracts with Customers, along with subsequent amendments to this standard. We applied the new standards using the modified retrospective approach under which the cumulative effect of initially applying the standards was recorded as an adjustment to retained earnings as of the date of adoption. As such, prior periods have not been revised and continue to be reported under the accounting standards in effect for those periods. Further information regarding the adoption of this standard can be found in Note 2.

Beginning in 2018, our product revenue is recognized when control of the goods is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods. In most cases, control is transferred when products are shipped. We recognize the vast majority of our service revenue as the services are provided. The majority of our contracts are for the shipment of tangible products or the delivery of services that have a single performance obligation or include multiple performance obligations where control is transferred at the same time.

During previous years, revenue was recognized when (1) persuasive evidence of an arrangement existed, (2) delivery occurred or services were rendered, (3) the sales price was fixed or determinable, and (4) collectibility was reasonably assured. Our product revenue was recognized upon shipment or customer receipt, based upon the transfer of title, and we recognized the majority of our service revenue as the services were provided.

In all periods, revenue is presented in the consolidated statements of income net of rebates, discounts, amortization of prepaid product discounts, and sales tax collected concurrent with revenue-producing activities. Many of our check supply contracts with financial institutions provide for rebates on certain products. We record these rebates as reductions of revenue and as accrued liabilities on our consolidated balance sheets when the related revenue is recognized. Amounts billed to customers for shipping and handling are included in revenue, while the related shipping and handling costs are reflected in cost of products and are accrued when the related revenue is recognized.

When another party is involved in providing goods or services to a customer, we must determine whether our obligation is to provide the specified good or service itself (i.e., we are the principal in the transaction) or to arrange for that good or service to be provided by the other party (i.e., we are an agent in the transaction). When we are responsible for satisfying a performance obligation, based on our ability to control the product or service provided, we are considered the principal and revenue is recognized for the gross amount of consideration. When the other party is primarily responsible for satisfying a performance obligation, we are considered the agent and revenue is recognized in the amount of any fee or commission to which we are entitled. In the case of our Financial Services rewards, incentive and loyalty programs, we receive payments from consumers or our clients for the products and services provided, including hotel stays, gift cards and merchandise. We have determined that we are an agent in these transactions and this revenue is recorded net of the related fulfillment costs. Within our Small Business Services segment, we sell certain products and services through a network of Safeguard distributors. We have determined that we are the principal in these transactions and revenue is recorded for the gross amount of consideration.

Certain of our contracts for data-driven marketing solutions and treasury management outsourcing services within Financial Services have variable consideration that is contingent on either the success of the marketing campaign ("pay-for-performance") or the volume of outsourcing services provided. We recognize revenue for estimated variable consideration as services are provided based on the most likely amount to be realized. Revenue is recognized to the extent that it is probable that a significant reversal of revenue will not occur when the contingency is resolved. Estimates regarding the recognition of variable consideration are updated each quarter. Typically, the amount of consideration for these contracts is finalized within 4 months, although pricing under certain of our outsourcing contracts may be based on annual volume commitments. Revenue recognized from these contracts was approximately $130,000 in 2018. Upon adoption of ASU No. 2014-09, we accelerated the recognition of a portion of this variable consideration.

Our payment terms vary by type of customer and the products or services offered. The time period between invoicing and when payment is due is not significant. For certain products, services and customer types, we require payment before the products or services are delivered to the customer. When a customer pays in advance, primarily for treasury management solutions and web hosting services, we defer the revenue and recognize it as the services are performed, generally over a period of less than 1 year. Deferred revenue is included in accrued liabilities and other non-current liabilities in our consolidated balance sheets. The increase of $5,704 in deferred revenue during the year ended December 31, 2018 was driven primarily by cash payments received in advance of satisfying our performance obligations, partially offset by the recognition of $45,405 of revenue that was included in deferred revenue as of December 31, 2017.

In addition to the amounts included in deferred revenue, we will recognize revenue in future periods related to remaining performance obligations for certain of our data-driven marketing and treasury management solutions. Generally, these contracts have terms of 1 year or less and many have terms of 3 months or less. The amount of revenue related to these unsatisfied performance obligations is not significant to our annual consolidated revenue. When the revenue recognized for uncompleted contracts exceeds the amount of customer billings and the right to receive the consideration is conditional, a contract asset is recorded. These amounts are included in revenue in excess of billings on the consolidated balance sheets and totaled $19,705 as of December 31, 2018 and $7,387 as of December 31, 2017. Additionally, we record an asset for unbilled receivables when the revenue recognized has not been billed to customers in accordance with contractually stated billing terms and the right to receive the consideration is unconditional. These assets are also included in revenue in excess of billings on the consolidated balance sheets and totaled $10,753 as of December 31, 2018 and $8,992 as of December 31, 2017.

At times, a financial institution client may terminate its check supply contract with us prior to the end of the contract term. In many cases, the financial institution is contractually required to remit a contract termination payment. Such payments are recorded as revenue when the termination agreement is executed, provided that we have no further performance obligations and collection of the funds is assured. If we have further performance obligations following the execution of a contract termination agreement, we record the related revenue over the remaining service period.

Beginning in 2018, sales commissions related to obtaining check supply and treasury management solution contracts within Financial Services are recorded as other non-current assets in the consolidated balance sheets and are amortized on the straight-line basis as SG&A expense. Amortization of these amounts on the straight-line basis approximates the timing of the transfer of goods or services to the customer. Generally, these amounts are being amortized over periods of 3 to 6 years.

Employee share-based compensation – Our share-based compensation consists of non-qualified stock options, restricted stock units, restricted stock, performance share awards and an employee stock purchase plan. Employee share-based compensation expense is included in total cost of revenue and in SG&A expense in our consolidated statements of income, based on the functional areas of the employees receiving the awards, and is recognized as follows:

Earnings per share – We calculate earnings per share using the two-class method, as we have unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalent payments. The two-class method is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. Basic earnings per share is based on the weighted-average number of common shares outstanding during the year. Diluted earnings per share is based on the weighted-average number of common shares outstanding during the year, adjusted to give effect to potential common shares such as stock options and shares to be issued under our employee stock purchase plan.
