Accounting Policies [Abstract]
Significant accounting policies	Significant accounting policies Nature of operations – We provide a selection of customer life cycle management solutions that help our customers acquire and engage their customers across multiple channels. We offer a wide range of services and products to small businesses, including hosting and domain name services, logo and web design, search engine marketing and optimization, email marketing, payroll services, and business incorporation and organization services, in addition to our checks, forms and promotional product offerings. For financial institutions, we offer our check program solutions, as well as a selection of financial technology solutions, including data-driven marketing, including outsourced marketing campaign targeting and execution; treasury management solutions, including accounts receivable processing and remote deposit capture; and digital engagement solutions, including loyalty and rewards programs. We are also a leading printer of checks and accessories sold directly to consumers. Consolidation – The consolidated financial statements include the accounts of Deluxe Corporation and its wholly-owned subsidiaries. All intercompany accounts, transactions and profits have been eliminated. 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. Inventories and supplies – Inventories are stated at the lower of cost or net realizable value. Cost is calculated on the first-in, first-out basis. Supplies consist of items not used directly in the production of goods, such as maintenance and other supplies utilized in the production area. 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. Long-term investments – Long-term investments consist primarily of cash surrender values of company-owned life insurance policies. Certain of these policies fund amounts due under our deferred compensation plan and our inactive supplemental executive retirement plan. Further information regarding these plans can be found in Notes 13 and 14. 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. Impairment of long-lived assets and amortizable intangibles – We evaluate the recoverability of property, plant, equipment and amortizable intangibles not held for sale whenever events or changes in circumstances indicate that an asset group's 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. The evaluation of asset impairment requires us to make assumptions about future cash flows over the life of the asset group being evaluated. These assumptions require significant judgment and actual results may differ from assumed and estimated amounts. 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. Derivative financial instruments – Information regarding our derivative financial instruments is included in Note 7. We did not have any derivative instruments outstanding as of December 31, 2018 or December 31, 2017, as we settled all of our interest rate swaps during 2016. We do not use derivative financial instruments for speculative or trading purposes. Our policy is that all derivative transactions must be linked to an existing balance sheet item or firm commitment, and the notional amount cannot exceed the value of the exposure being hedged. 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 cu

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New accounting pronouncements	New accounting pronouncements The following discusses the impact of each accounting standard adopted on January 1, 2018: ASU No. 2014-09 – In May 2014, the Financial Accounting Standards Board (FASB) issued ASU No. 2014-09, Revenue from Contracts with Customers . This standard provides revenue recognition guidance for any entity that enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets, unless those contracts are within the scope of other accounting standards. In addition, the FASB subsequently issued several amendments to the standard. We adopted this standard and all the related amendments on January 1, 2018 using the modified retrospective method. We applied the new guidance to uncompleted contracts as of January 1, 2018 and recorded the cumulative effect of initially applying the standard as an adjustment to retained earnings as of the date of adoption, with the offset to revenue in excess of billings, other non-current assets and deferred income tax liabilities. We elected the following practical expedients allowed under the guidance: • We considered the impact of all contract modifications completed prior to January 1, 2018; • We disregard the effects of a financing component when the period between payment and performance is 1 year or less; • We account for shipping and handling activities that occur after the customer has obtained control of a good as a fulfillment cost; and • We expense sales commissions as incurred when the amortization period would have been 1 year or less. Election of these practical expedients did not have a significant impact on our results of operations or financial position. Prior period financial information has not been revised and continues to be reported under the accounting standards in effect for those periods. Adoption of this guidance did not have a significant impact on our results of operations, financial position or cash flows during the year ended December 31, 2018, and we do not expect it to have a significant impact on an ongoing basis. The new guidance also expands the required financial statement disclosures regarding revenue. Our revenue recognition accounting policy can be found in Note 1 and disaggregated revenue information can be found in Note 18. The cumulative effect of adoption of the new revenue guidance on our consolidated balance sheet as of January 1, 2018 was as follows: (in thousands) Balance as of December 31, 2017 Adjustments due to adoption of ASU No. 2014-09 Balance as of January 1, 2018 Revenue in excess of billings $ 16,379 $ 960 $ 17,339 Total current assets 392,966 960 393,926 Other non-current assets 159,756 5,733 165,489 Total assets $ 2,208,827 $ 6,693 $ 2,215,520 Deferred income taxes 50,543 1,727 52,270 Retained earnings 1,004,657 4,966 1,009,623 Total liabilities and shareholders' equity $ 2,208,827 $ 6,693 $ 2,215,520 The impact of the new revenue guidance on our consolidated statement of income for the year ended December 31, 2018 and on our consolidated balance sheet as of December 31, 2018 was as follows: (in thousands) As reported Effect of adoption Amounts without adoption of ASU No. 2014-09 Year Ended December 31, 2018 Service revenue $ 546,192 $ (717 ) $ 545,475 Total revenue 1,998,025 (717 ) 1,997,308 Cost of services (244,108 ) 625 (243,483 ) Total cost of revenue (791,748 ) 625 (791,123 ) Gross profit 1,206,277 (92 ) 1,206,185 Selling, general and administrative expense (854,000 ) (749 ) (854,749 ) Operating income 231,221 (841 ) 230,380 Income before income taxes 212,631 (841 ) 211,790 Income tax provision (63,001 ) 209 (62,792 ) Net income $ 149,630 $ (632 ) $ 148,998 December 31, 2018 Revenue in excess of billings $ 30,458 $ (1,052 ) $ 29,406 Total current assets 450,046 (1,052 ) 448,994 Other non-current assets 196,108 (6,482 ) 189,626 Total assets $ 2,305,096 $ (7,534 ) $ 2,297,562 Accrued liabilities $ 284,281 $ (209 ) $ 284,072 Total current liabilities 392,050 (209 ) 391,841 Deferred income taxes 46,680 (1,727 ) 44,953 Retained earnings 927,345 (5,598 ) 921,747 Total liabilities and shareholders' equity $ 2,305,096 $ (7,534 ) $ 2,297,562 ASU No. 2016-01 – In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities . This standard is intended to improve the recognition, measurement, presentation and disclosure of financial instruments. We adopted this standard on January 1, 2018. This standard had no impact on our results of operations or financial position. Our financial statement disclosures in Note 8 related to financial instruments have been modified to comply with the new standard. ASU No. 2016-16 – In October 2016, the FASB issued ASU No. 2016-16, Intra-Entity Transfers of Assets Other Than Inventory . This standard requires recognition of the tax effects resulting from the intercompany sale of an asset when the transfer occurs. Previously, the tax effects were deferred until the transferred asset was sold to a third party. We adopted this standard on January 1, 2018. No adjustment was required to opening retained earnings. Application of this standard has not had a significant impact on our results of operations or financial position and we do not expect it to have a significant impact on an ongoing basis. ASU No. 2016-18 – In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash . This standard requires the statement of cash flows to explain the change during the period in the total of cash, cash equivalents, restricted cash and restricted cash equivalents. This standard was effective for us on January 1, 2018 and was required to be applied retrospectively. Accordingly, we have revised our consolidated statements of cash flows to include cash and cash equivalents included in funds held for customers with cash, cash equivalents, restricted cash and restricted cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statements of cash flows. Further information concerning adoption of this standard can be found in Summarized Quarterly Financial Data. The impact of this revision on our consolidated statements of cash flows for the years ended December 31, 2017 and December 31, 2016 was as follows: (in thousands) As previously reported Effect of adoption As revised Year Ended December 31, 2017 Purchases of customer funds marketable securities $ — $ (7,737 ) $ (7,737 ) Proceeds from customer funds and corporate marketable securities 3,500 7,737 11,237 Net cash used by investing activities (180,891 ) — (180,891 ) Net change in customer funds obligations — (6,007 ) (6,007 ) Net cash used by financing activities (176,949 ) (6,007 ) (182,956 ) Effect of exchange rate change on cash, cash equivalents, restricted cash and restricted cash equivalents 2,075 3,295 5,370 Net change in cash, cash equivalents, restricted cash and restricted cash equivalents (17,334 ) (2,712 ) (20,046 ) Cash, cash equivalents, restricted cash and restricted cash equivalents, beginning of year 76,574 72,291 148,865 Cash, cash equivalents, restricted cash and restricted cash equivalents, end of year (Note 3) $ 59,240 $ 69,579 $ 128,819 Year Ended December 31, 2016 Payments for acquisitions, net of cash acquired $ (270,939 ) $ 31,275 $ (239,664 ) Purchases of customer funds marketable securities — (7,869 ) (7,869 ) Proceeds from customer funds and corporate marketable securities 1,635 7,869 9,504 Net cash used by investing activities (310,786 ) 31,275 (279,511 ) Net change in customer funds obligations — 1,723 1,723 Net cash provided by financing activities 4,275 1,723 5,998 Effect of exchange rate change on cash, cash equivalents, restricted cash and restricted cash equivalents 1,346 1,017 2,363 Net change in cash, cash equivalents, restricted cash and restricted cash equivalents 14,147 34,015 48,162 Cash, cash equivalents, restricted cash and restricted cash equivalents, beginning of year 62,427 38,276 100,703 Cash, cash equivalents, restricted cash and restricted cash equivalents, end of year (Note 3) $ 76,574 $ 72,291 $ 148,865 ASU No. 2017-01 – In January 2017, the FASB issued ASU No. 2017-01, Clarifying the Definition of a Business . This standard revises the definition of a business, which affects many areas of accounting, such as business combinations and disposals and goodwill impairment. The revised definition of a business will likely result in more acquisitions being accounted for as asset acquisitions, as opposed to business combinations. We adopted this standard on January 1, 2018, applying the guidance to transactions occurring on or after this date. Adoption of the standard did not have a significant impact on our results of operations or financial position. ASU No. 2017-07 – In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . This standard requires that the service cost component of net periodic benefit expense be recognized in the same statement of income caption(s) as other compensation costs, and requires that the other components of net periodic benefit expense be recognized in the non-operating section of the statement of income. In addition, only the service cost component of net periodic benefit expense is eligible for capitalization when applicable. We adopted this standard on January 1, 2018. The reclassification of the other components of our net periodic benefit income was applied on a retrospective basis. As such, we have revised our results of operations for previous periods. We utilized the practical expedient for adoption allowing us to use the amounts previously disclosed in our postretirement benefits footnote as the basis for revising prior periods. As there is no service cost associated with our plans, we reclassified the entire amount of our net periodic benefit income from cost of revenue and SG&A expense to other income in our consolidated statements of income. In addition, we no longer include any portion of net periodic benefit income in amounts capitalized for inventory or internal-use software, as only the service cost component is eligible for capitalization. This change did not have a significant impact on our results of operations or financial position. The impact of the revision on our consolidated statements of income for the years ended December 31, 2017 and December 31, 2016 was as follows: (in thousands) As previously reported Effect of adoption As revised Year Ended December 31, 2017 Cost of products $ (529,088 ) $ (550 ) $ (529,638 ) Cost of services (213,002 ) (67 ) (213,069 ) Total cost of revenue (742,090 ) (617 ) (742,707 ) Gross profit 1,223,466 (617 ) 1,222,849 Selling, general and administrative expense (828,832 ) (1,399 ) (830,231 ) Operating income 331,192 (2,016 ) 329,176 Other income 2,994 2,016 5,010 Net income $ 230,155 $ — $ 230,155 Year Ended December 31, 2016 Cost of products $ (534,390 ) $ (516 ) $ (534,906 ) Cost of services (132,851 ) (56 ) (132,907 ) Total cost of revenue (667,241 ) (572 ) (667,813 ) Gross profit 1,181,821 (572 ) 1,181,249 Selling, general and administrative expense (805,970 ) (1,268 ) (807,238 ) Operating income 368,727 (1,840 ) 366,887 Other income 1,819 1,840 3,659 Net income $ 229,382 $ — $ 229,382 ASU No. 2017-09 – In May 2017, the FASB issued ASU No. 2017-09, Scope of Modification Accounting . This standard provides guidance about which changes to the terms or conditions of a share-based payment award require modification accounting, which may result in a different fair value for the award. We adopted this standard on January 1, 2018, and it is being applied prospectively to awards modified on or after this date. Application of this standard did not have a significant impact on our results of operations or financial position and we do not expect it to have a significant impact on an ongoing basis. ASU No. 2018-02 – In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . This standard allows companies to make an election to reclassify from accumulated other comprehensive income to retained earnings the stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (the "2017 Tax Act"). We elected to early adopt this standard on January 1, 2018, applying it in the period of adoption. As such, we reclassified $6,867 from accumulated other comprehensive loss to retained earnings. This represents the effect of the change in the United States federal corporate income tax rate on the gross deferred tax amount at the date of enactment of the 2017 Tax Act related to items remaining in accumulated other comprehensive loss. ASU No. 2018-05 – In March 2018, the FASB issued ASU No. 2018-05, Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin (SAB) No. 118 . This standard added to the FASB Codification the guidance provided by the SEC in December 2017 regarding the accounting for the 2017 Tax Act. We complied with SAB No. 118 when preparing our annual consolidated financial statements for the year ended December 31, 2017. During 2017, reasonable estimates were used to determine certain impacts of the 2017 Tax Act, including our 2017 deferred income tax activity and the amount of post-1986 unremitted foreign earnings subject to the repatriation toll charge. We finalized our accounting for the 2017 Tax Act during the fourth quarter of 2018. Our income tax provision for the year ended December 31, 2018 was reduced $1,700 for adjustments to our accounting for the 2017 Tax Act, primarily a reduction in the amount accrued for the repatriation toll charge. Other accounting pronouncements adopted – In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurements . This standard removes, modifies and adds certain disclosures related to recurring and nonrecurring fair value measurements. On September 30, 2018, we early adopted the provisions of the standard that remove and modify disclosure requirements. This adoption had minimal impact on our fair value disclosures in Note 8. The additional disclosures required under the new guidance are effective for us on January 1, 2020. In August 2018, the FASB issued ASU No. 2018-14, Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans . This standard modifies certain disclosures related to defined benefit pension and other postretirement plans and requires adoption on a retrospective basis to all periods presented. We early adopted this standard on December 31, 2018 and included the modified disclosures in Note 14. Accounting pronouncements not yet adopted – In February 2016, the FASB issued ASU No. 2016-02, Leasing . This standard is intended to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities for virtually all leases and by requiring the disclosure of key information about leasing arrangements. In July 2018, the FASB issued two amendments to ASU No. 2016-02: ASU No. 2018-10, Codification Improvements to Topic 842, Leases , which amends narrow aspects of the guidance in ASU No. 2016-02, and ASU No. 2018-11, Targeted Improvements, which provides an optional transition method under which comparative periods presented in financial statements in the period of adoption would not be restated. All of these standards are effective for us on January 1, 2019. They are required to be adopted using a modified retrospective approach, and we plan to elect the optional transition method under ASU No. 2018-11. We established an implementation team to evaluate and identify the impact of these standards on our financial position, results of operations and cash flows. We are currently completing the assessment of our leasing arrangements and the implementation of software to meet the reporting requirements of the standard. We anticipate that we will elect the practical expedient package outlined in ASU No. 2016-02 under which we do not have to reassess whether an arrangement contains a lease, we can carryforward our previous classification of leases as either operating or capital leases, and we do not have to reassess previously recorded initial direct costs. Additionally, we anticipate that we will make the following policy elections: • We will exclude leases with original terms of 12 months or less from lease assets and liabilities; • We will separate nonlease components from the associated lease component for real estate leases; and • We will use the accounting lease term when determining the incremental borrowing rate for leases with renewal options. We estimate that we will recognize, as of January 1, 2019, lease assets and liabilities of at least $45,000 for leases classified as operating leases under previous guidance. We do not expect the new guidance to have a significant impact on our consolidated statements of income or on our consolidated statements of cash flows on an ongoing basis. In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments . This standard introduces new guidance for the accounting for credit losses on instruments within its scope, including trade and loans receivable and available-for-sale debt securities. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses, which clarifies that receivables arising from operating leases are not within the scope of ASU No. 2016-13. These standards are effective for us on January 1, 2020 and require adoption using a modified retrospective approach. We do not expect the application of these standards to have a significant impact on our results of operations or financial position. In August 2018, the FASB issued ASU No. 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract

Property, plant and equipment – Property, plant and equipment was comprised of the following at December 31: 2018 2017 (in thousands) Gross carrying amount Accumulated depreciation Net carrying amount Gross carrying amount Accumulated depreciation Net carrying amount Land and improvements $ 28,199 $ (8,167 ) $ 20,032 $ 28,220 $ (8,064 ) $ 20,156 Buildings and improvements 116,348 (83,317 ) 33,031 114,793 (80,168 ) 34,625 Machinery and equipment 313,000 (275,721 ) 37,279 299,645 (269,788 ) 29,857 Property, plant and equipment $ 457,547 $ (367,205 ) $ 90,342 $ 442,658 $ (358,020 ) $ 84,638 Assets held for sale – Assets held for sale as of December 31, 2018 consisted of 1 small business customer list. Assets held for sale as of December 31, 2017 included 2 providers of printed and promotional products and 2 small business distributors, all of which were sold during 2018. Also during 2018, we sold several small business customer lists that did not meet the requirements to be classified as held for sale in the December 31, 2017 consolidated balance sheet. We determined that the assets sold would be better positioned for long-term growth if they were managed by independent distributors. Subsequent to the sales, the businesses and customer lists are owned by independent distributors that are part of our Safeguard distributor network. As such, our revenue is not impacted by these sales and the impact to our costs is not significant. We entered into aggregate notes receivable of $35,616 in conjunction with these sales and we recognized aggregate net gains of $15,641 within SG&A expense in the 2018 consolidated statement of income. During 2017, we sold a provider of printed and promotional products, assets associated with certain custom printing activities and 3 small business distributors. We entered into aggregate notes receivable of $24,497 in conjunction with these sales and we recognized aggregate net gains of $8,703 within SG&A expense in the 2017 consolidated statement of income. The assets sold during 2018 and 2017, as well as the customer list held for sale as of December 31, 2018, were included in our Small Business Services segment and consisted primarily of intangible assets. During 2017, we recorded aggregate pre-tax asset impairment charges of $8,250 related to a small business distributor sold during the second quarter of 2017. The impairment charges reduced the carrying value of the business to its fair value less costs to sell, as we finalized the sale of this business. We are actively marketing the remaining asset held for sale and we expect the selling price will equal or exceed its current carrying value. Net assets held for sale consisted of the following at December 31: (in thousands) 2018 2017 Balance sheet caption Current assets $ — $ 4 Other current assets Intangibles 1,350 8,459 Assets held for sale Goodwill — 3,566 Assets held for sale Other non-current assets — 207 Assets held for sale Net assets held for sale $ 1,350 $ 12,236 Intangibles – Intangibles were comprised of the following at December 31: 2018 2017 (in thousands) Gross carrying amount Accumulated amortization Net carrying amount Gross carrying amount Accumulated amortization Net carrying amount Indefinite-lived intangibles: Trade name (1) $ — $ — $ — $ 19,100 $ — $ 19,100 Amortizable intangibles: Internal-use software 388,477 (308,313 ) 80,164 359,079 (284,074 ) 75,005 Customer lists/relationships (2) 379,570 (170,973 ) 208,597 343,589 (121,729 ) 221,860 Trade names 50,645 (26,204 ) 24,441 36,931 (19,936 ) 16,995 Technology-based intangibles 39,300 (14,007 ) 25,293 31,800 (6,400 ) 25,400 Software to be sold 36,900 (15,430 ) 21,470 36,900 (11,204 ) 25,696 Other 700 (700 ) — 1,800 (1,590 ) 210 Amortizable intangibles 895,592 (535,627 ) 359,965 810,099 (444,933 ) 365,166 Intangibles $ 895,592 $ (535,627 ) $ 359,965 $ 829,199 $ (444,933 ) $ 384,266 (1) During the third quarter of 2018, we recorded a pre-tax asset impairment charge of $19,100 for our indefinite-lived trade name.

Business Combinations [Abstract]
Acquisitions	Acquisitions We regularly complete business combinations that align with our business strategy. The assets and liabilities acquired are recorded at their estimated fair values, and the results of operations of each acquired business are included in our consolidated statements of income from their acquisition dates. Transaction costs related to acquisitions are expensed as incurred and are included in SG&A expense in the consolidated statements of income. Transaction costs totaled $1,719 in 2018 , $2,342 in 2017 and $4,944 in 2016 . The acquisitions completed during the past 3 years were cash transactions, funded by use of our revolving credit facility. We completed these acquisitions primarily to increase our mix of marketing solutions and other services revenue, to add financial technology and web services capabilities, to improve our product and service offerings and to reach new customers. 2018 acquisitions – During 2018, we completed the following acquisitions that were included within our Small Business Services segment: • In March 2018, we acquired all of the equity of Logomix Inc. (Logomix), a self-service marketing and branding platform that helps small businesses create logos and custom marketing products. The allocation of the purchase price based upon the estimated fair values of the assets acquired and liabilities assumed resulted in nondeductible goodwill of $29,451 . The acquisition resulted in goodwill as we expect to accelerate revenue growth by combining our capabilities with Logomix's platform. • In June 2018, we acquired selected assets of Velocity Servers, Inc., doing business as ColoCrossing, a data center solutions, cloud hosting and infrastructure colocation provider of dedicated hosting services. The preliminary allocation of the purchase price based upon the estimated fair values of the assets acquired and liabilities assumed resulted in tax-deductible goodwill of $9,689 . The acquisition resulted in goodwill as we expect to accelerate revenue growth by bringing colocation services into our portfolio of hosting services. We expect to finalize the allocation of the purchase price in the first quarter of 2019, when our valuation of the acquired intangible assets is complete. • In December 2018, we acquired selected assets of My Corporation Business Services, Inc., a provider of business incorporation and organization services. The preliminary allocation of the purchase price based upon the estimated fair values of the assets acquired and liabilities assumed resulted in tax-deductible goodwill of $20,348 . The acquisition resulted in goodwill as we expect to accelerate revenue growth by bringing these services into our portfolio of web services. We expect to finalize the allocation of the purchase price in 2019, when our valuation of the acquired intangible assets, as well as various other assets acquired and liabilities assumed, is complete. • During 2018, we acquired the operations of 3 small business distributors. The assets acquired consisted primarily of customer list intangible assets. As these small business distributors were previously part of our Safeguard distributor network, our revenue was not impacted by these acquisitions, and the impact to our costs was not significant. Within our Financial Services segment, we acquired the equity of REMITCO LLC (RemitCo) in August 2018. RemitCo was the remittance processing business of First Data Corporation. The preliminary allocation of the purchase price based upon the estimated fair values of the assets acquired and liabilities assumed resulted in tax-deductible goodwill of $46,419 and a customer list intangible asset of $36,000 . The acquisition resulted in goodwill as it expands the scale of our receivables management solutions, which allows us to take advantage of the ongoing market trend toward outsourcing technology-enabled services to trusted financial technology partners of scale. We expect to finalize the allocation of the purchase price by mid-2019, when our valuation of miscellaneous assets acquired and liabilities assumed is complete. 2017 acquisitions – During 2017, we completed the following acquisitions that were included within our Small Business Services segment: • In February 2017, we acquired selected assets of Panthur Pty Ltd (Panthur), an Australian web hosting and domain registration service provider. The allocation of the purchase price based upon the estimated fair values of the assets acquired and liabilities assumed resulted in nondeductible goodwill of $1,198 . The acquisition resulted in goodwill as we used Panthur's platform to selectively expand into foreign markets. • In July 2017, we acquired all of the equity of Digital Pacific Group Pty Ltd (Digital Pacific), an Australian web hosting and domain registration service provider. The allocation of the purchase price based upon the estimated fair values of the assets acquired and liabilities assumed resulted in nondeductible goodwill of $23,773 . The acquisition resulted in goodwill as we acquired enhanced web hosting capabilities that we used to selectively expand into foreign markets. • In September 2017, we acquired all of the equity of j2 Global Australia Pty Ltd, doing business as Web24, an Australian web hosting and domain registration service provider. The allocation of the purchase price based upon the estimated fair values of the assets acquired and liabilities assumed resulted in nondeductible goodwill of $2,731 . The acquisition resulted in goodwill as we used Web24's platform to selectively expand into foreign markets. • In November 2017, we acquired selected assets of Impact Marketing Specialists, Inc., which provides marketing solutions to real estate agents. • In December 2017, we acquired selected assets of SY Holdings, LLC, doing business as managed.com, a web hosting services provider. The allocation of the purchase price based upon the estimated fair values of the assets acquired and liabilities assumed resulted in tax-deductible goodwill of $266 . The acquisition resulted in goodwill as the expertise we acquired improved our customer mix and enhanced our portfolio of web services. • During 2017, we acquired the operations of several small business distributors. The assets acquired consisted primarily of customer list intangible assets. All but 1 of these distributors were previously part of our Safeguard distributor network. As such, our results of operations were not significantly impacted by these acquisitions. Within our Financial Services segment, we acquired all of the equity of RDM Corporation (RDM) of Canada in April 2017.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative financial instruments	Derivative financial instruments During 2011 and 2012, we entered into interest rate swaps, which we designated as fair value hedges, to hedge against changes in the fair value of a portion of our long-term debt. At the time we entered into these swaps, we were targeting a mix of fixed and variable rate debt, where we received a fixed rate and paid a variable rate based on the London Interbank Offered Rate (LIBOR). As of December 31, 2015, we had interest rate swaps with a notional amount of $200,000 that related to our long-term debt due in 2020. These swaps met the criteria for using the short-cut method for a fair value hedge based on the structure of the hedging relationship. As such, changes in the fair value of the derivatives and the related long-term debt were equal. The related long-term debt was retired during 2016 (Note 15) and we concurrently settled the interest rate swaps, resulting in a cash payment of $2,842

Fair Value Disclosures [Abstract]
Fair value measurements	Fair value measurements Annual asset impairment analyses – We evaluate the carrying value of goodwill and our indefinite-lived trade name as of July 31 of each year and between annual evaluations if events occur or circumstances change that would indicate a possible impairment. Our policy on impairment of indefinite-lived intangibles and goodwill, which is included in Note 1, explains our methodology for assessing impairment of these assets. • 2018 impairment analyses – In completing the 2018 annual impairment analysis of goodwill, we elected to perform a qualitative assessment for 5 of our reporting units and a quantitative assessment for 2 of our reporting units: Small Business Services Web Services and Small Business Services Indirect. Small Business Services Web Services includes our businesses that provide hosting and domain name services, logo and web design, search engine marketing and optimization, payroll services and business incorporation and organization services. Small Business Services Indirect consists primarily of our Safeguard distributor channel, former Safeguard distributors that we have purchased, and our independent dealer channel. The qualitative analyses evaluated factors, including, but not limited to, economic, market and industry conditions, cost factors and the overall financial performance of the reporting units. We also considered the quantitative analyses completed as of July 31, 2017, which indicated that the estimated fair values of the 5 reporting units exceeded their carrying values by approximate amounts between $64,000 and $1,405,000 , or by amounts between 50% and 314% above the carrying values of their net assets. In completing these assessments, we noted no changes in events or circumstances that indicated that it was more likely than not that the fair value of any reporting unit was less than its carrying amount. The quantitative analysis as of July 31, 2018 for the Small Business Services Web Services reporting unit indicated that the estimated fair value of the reporting unit exceeded its carrying value by approximately $63,000 , or 22% . The carrying value of this reporting unit's goodwill was $225,383 as of July 31, 2018. The quantitative analysis of the Small Business Services Indirect reporting unit indicated that the reporting unit's goodwill was fully impaired, resulting in a pre-tax goodwill impairment charge of $78,188 during the quarter ended September 30, 2018. The impairment charge was measured as the amount by which the reporting unit's carrying value exceeded its estimated fair value, limited to the carrying amount of goodwill. The analysis of this reporting unit, which incorporated the results of the annual strategic planning process completed during the third quarter of 2018, indicated lowered projected long-term revenue growth and profitability levels resulting from changes in strategy and focus and in the mix of products and services sold, including the continuing secular decline in check and forms usage. Additionally, our strategic plan reflected a shift in company resources to our growing businesses. Our indefinite-lived Safeguard trade name was included in the Small Business Services Indirect reporting unit. As of July 31, 2018, we completed a quantitative analysis of this asset that indicated the asset was fully impaired (level 3 fair value measurement), resulting in a pretax asset impairment charge of $19,100 . This impairment charge was driven by the same factors that resulted in the goodwill impairment charge, which indicated that any royalties attributable to the asset under our relief from royalty calculation had no future value. • 2017 impairment analyses – In conjunction with our annual strategic planning process during the third quarter of 2017, we made various changes to our internal reporting structure. As a result, we reassessed our operating segments and determined that no changes were required in our reportable operating segments. We also reassessed our previously determined reporting units and concluded that a realignment of a portion of our reporting units was required. As such, we reallocated the carrying value of goodwill to our revised reporting units based on their relative fair values. We analyzed goodwill for impairment immediately prior to this realignment by performing qualitative analyses for our Small Business Services reporting units and quantitative analyses for our Financial Services and Direct Checks reporting units. The qualitative analyses evaluated factors including, but not limited to, economic, market and industry conditions, cost factors and the overall financial performance of the reporting units. We also considered the last quantitative analysis we completed. In completing these assessments, we noted no changes in events or circumstances that indicated that it was more likely than not that the fair value of any reporting unit was less than its carrying amount, with the exception of our Small Business Services Safeguard reporting unit. The analysis of this reporting unit, which incorporated the results of the annual strategic planning process, indicated lowered projected long-term revenue growth and profitability levels resulting from changes in market trends and the mix of products and services sold, including the continuing secular decline in check and forms usage. As a result, we completed impairment analyses of the long-term assets of this reporting unit, excluding goodwill, and concluded that these assets were not impaired. We then completed the quantitative analysis of the reporting unit, utilizing the income approach outlined in Note 1. This quantitative analysis indicated that this reporting unit's goodwill was fully impaired and resulted in a non-cash pre-tax goodwill impairment charge of $28,379 during the quarter ended September 30, 2017. The impairment charge was measured as the amount by which the reporting unit's carrying value exceeded its estimated fair value, limited to the carrying amount of goodwill. Immediately subsequent to the realignment of our reporting unit structure, we completed a quantitative analysis for all of our reporting units. This quantitative analysis as of July 31, 2017 indicated that the estimated fair values of our reporting units exceeded their carrying values by approximate amounts between $64,000 and $1,405,000 , or by amounts between 36% and 314% above the carrying values of their net assets. In completing the 2017 annual impairment analysis of our indefinite-lived trade name, we elected to perform a quantitative assessment, which indicated that the calculated fair value of the asset exceeded its carrying value of $19,100 by approximately $16,000 as of July 31, 2017. • 2016 impairment analyses – In completing the 2016 annual goodwill impairment analyses, we elected to perform qualitative assessments for all of our reporting units to which goodwill was assigned, with one exception. We elected to perform a quantitative analysis for our Financial Services Commercial reporting unit. This reporting unit was acquired subsequent to our 2014 annual impairment analysis and the quantitative analysis completed as of July 31, 2015 indicated that the estimated fair value of this reporting unit exceeded its carrying value by approximately 13% . The quantitative assessment completed for this reporting unit as of July 31, 2016 indicated that its estimated fair value exceeded its carrying value by approximately 49% . Total goodwill for this reporting unit was approximately $45,000 as of the date of the 2016 assessment. Our qualitative analyses completed during 2016 evaluated factors including, but not limited to, economic, market and industry conditions, cost factors and the overall financial performance of the reporting units. We also considered the quantitative analyses we completed as of July 31, 2014. In completing these assessments, we noted no changes in events or circumstances which indicated that it was more likely than not that the fair value of any reporting unit was less than its carrying amount. In the completing the 2016 annual impairment analysis of our indefinite-lived trade name, we elected to perform a quantitative assessment, which indicated that the calculated fair value of the asset exceeded its carrying value of $19,100 by approximately $32,000 as of July 31, 2016. Based on the results of our annual impairment analyses, we recorded no impairment charges during 2016. Other non-recurring asset impairment analyses – During the fourth quarter of 2018, we performed a quantitative analysis of our Financial Services Data-Driven Marketing reporting unit. Revenue for this reporting unit was below our projections driven by higher mortgage lending rates, which result in less lending activity for our financial institution clients and thus, may cause them to reduce their marketing spending, as well as a large client electing to do certain of its marketing in-house. The quantitative analysis as of December 31, 2018 indicated that the estimated fair value of the reporting unit exceeded its carrying value by approximately $105,000 , or 36% . As such, no goodwill impairment charge was recorded for this reporting unit. The carrying value of this reporting unit's goodwill was $186,388 as of December 31, 2018. During the third quarter of 2018, we recorded pre-tax asset impairment charges of $1,882 for Financial Services customer list intangible assets related to 2 distributors we acquired in 2015. Based on higher than anticipated customer attrition, we determined that the customer lists were partially impaired as of July 31, 2018. During the first quarter of 2018, we recorded a pre-tax asset impairment charge of $2,149 related to a Small Business Services customer list intangible asset. Based on changes in the customer base of one of our small business distributors, we determined that the customer list asset was fully impaired as of March 31, 2018. We utilized the discounted value of estimated future cash flows to estimate the fair values of these asset groups. During 2017, we recorded aggregate pre-tax asset impairment charges of $8,250 related to a small business distributor that was classified as held for sale in the consolidated balance sheets prior to its sale during the second quarter of 2017. The impairment charges were calculated based on ongoing negotiations for the sale of the business and reduced its carrying value to its fair value less costs to sell by reducing the carrying value of the related customer list intangible asset. Further information regarding assets held for sale can be found in Note 3. During the quarter ended September 30, 2017, we decided that we would no longer utilize our Small Business Services NEBS ® trade name in the marketplace, and we recorded a non-cash pre-tax asset impairment charge of $14,752 to write down the remaining book value of this trade name to a fair value of $0 . Also during the quarter ended September 30, 2017, we recorded pre-tax asset impairment charges of $3,499 related to other long-lived assets within Small Business Services, primarily internal-use software related to an order capture system. During the third quarter of 2017, we signed a contract for customer relationship management services that resulted in our decision to no longer utilize a portion of this software. As such, the remaining net book value of the assets was written down to a fair value of $0 . Information regarding these other nonrecurring asset impairment analyses was as follows: Fair value measurements using Fair value as of measurement date Quoted prices in active markets for identical assets Significant other observable inputs Significant unobservable inputs Asset impairment charge (in thousands) (Level 1) (Level 2) (Level 3) 2018 analyses: Customer list (Small Business Services) $ — $ — $ — $ — $ 2,149 Customer lists (Financial Services) (1) 4,223 — — 4,223 1,882 Total $ 4,031 2017 analyses: Trade name $ — $ — $ — $ — $ 14,752 Assets held for sale 3,500 — — 3,500 8,250 Other — — — — 3,499 Total $ 26,501 (1) The fair value presented is for the entire asset group that includes the impaired customer lists. Acquisitions – For all acquisitions, we are required to measure the fair value of the net identifiable tangible and intangible assets and liabilities acquired. Information regarding our acquisitions can be found in Note 6 and information regarding the useful lives of acquired intangibles can be found in Note 3. The identifiable net assets acquired during the past 3 years were comprised primarily of customer list intangible assets, technology-based intangible assets, trade names and software. The fair value of the more significant acquired customer lists was estimated using the multi-period excess earnings method. This valuation model estimates revenues and cash flows derived from the asset and then deducts portions of the cash flow that can be attributed to supporting assets, such as a trade name or fixed assets, that contributed to the generation of the cash flows. The resulting cash flow, which is attributable solely to the customer list asset, is then discounted at a rate of return commensurate with the risk of the asset to calculate a present value. The estimated fair value of the remainder of our acquired customer lists was estimated by discounting the estimated cash flows expected to be generated by the assets. Key assumptions used in these calculations included same-customer revenue growth rates, estimated earnings and estimated customer retention rates based on the acquirees' historical information. The estimated fair value of the acquired technology-based intangibles, trade names and a portion of the acquired software was estimated using the relief from royalty method, which calculates the cost savings associated with owning rather than licensing the assets. Assumed royalty rates were applied to projected revenue for the estimated remaining useful lives of the assets to estimate the royalty savings. Royalty rates are selected based on the attributes of the asset, including its recognition and reputation in the industry, and in the case of trade names, with consideration of the specific profitability of the products sold under a trade name and supporting assets. The fair value of the remainder of the acquired software was estimated using the cost of reproduction method. The primary components of the software were identified and the estimated cost to reproduce the software was calculated based on historical data provided by the acquirees. For liabilities for contingent consideration recorded in conjunction with our acquisitions, we determined the fair value as of the acquisition dates by discounting to present value the probability-weighted contingent payments expected to be made. Key assumptions used in these calculations included the discount rate; projected revenue, gross profit or operating income, as appropriate, based on projected financial results of the acquired businesses from the perspective of an unrelated market participant; and factors indicating the probability of achieving the forecasted revenue, gross profit or operating income. The liabilities for contingent consideration related primarily to the acquisitions of Verify Valid and a small business distributor during 2015 and the acquisition of Data Support Systems during 2016. Under the Verify Valid and Data Support Systems agreements, there are no maximum amounts of contingent payments specified , although payments are based on a percentage of the revenue or operating income generated by the business. Recurring fair value measurements – Funds held for customers included cash equivalents and available-for-sale debt securities (Note 3). The cash equivalents consisted of a money market fund investment that is traded in an active market. Because of the short-term nature of the underlying investments, the cost of this investment approximates its fair value. Available-for-sale debt securities consisted of a mutual fund investment that invests in Canadian and provincial government securities and investments in Canadian guaranteed investment certificates (GIC's) with maturities of 1 year or less. The mutual fund is not traded in an active market and its fair value is determined by obtaining quoted prices in active markets for the underlying securities held by the fund. The fair value of the GIC's approximated cost due to their relatively short duration. Unrealized gains and losses, net of tax, are included in accumulated other comprehensive loss in the consolidated balance sheets. The cost of securities sold is determined using the average cost method. Realized gains and losses are included in revenue in the consolidated statements of income and were not significant during the past 3 years. The fair value of accrued contingent consideration is remeasured each reporting period. Increases or decreases in projected revenue, gross profit or operating income, as appropriate, and the related probabilities of achieving the forecasted results, may result in a higher or lower fair value measurement. Changes in fair value resulting from changes in the timing, amount of, or likelihood of contingent payments are included in SG&A expense in the consolidated statements of income. Changes in fair value resulting from accretion for the passage of time are included in interest expense in the consolidated statements of income. Changes in accrued contingent consideration were as follows: (in thousands) 2018 2017 2016 Balance, beginning of year $ 3,623 $ 4,682 $ 5,861 Acquisition date fair value 100 — 1,132 Change in fair value 610 1,190 (1,174 ) Payments (1,937 ) (2,249 ) (1,137 ) Balance, end of year $ 2,396 $ 3,623 $ 4,682 The fair value of interest rate swaps outstanding during 2016 (Note 7) was determined at each reporting date by means of a pricing model utilizing readily observable market interest rates. The change in fair value was determined as the change in the present value of estimated future cash flows discounted using the LIBOR rate. The interest rate swaps related to our long-term debt due in 2020 that we settled during the fourth quarter of 2016. The swaps met the criteria for using the short-cut method for a fair value hedge based on the structure of the hedging relationship. As such, changes in the fair value of the derivative and the related long-term debt were equal and were as follows for the year ended December 31, 2016: (in thousands) 2016 Gain from derivatives $ 1,200 Loss from change in fair value of hedged debt (1,200 ) Net effect on interest expense $ — Information regarding the fair values of our financial instruments was as follows: Fair value measurements using December 31, 2018 Quoted prices in active markets for identical assets Significant other observable inputs Significant unobservable inputs (in thousands) Carrying value Fair value (Level 1) (Level 2) (Level 3) Measured at fair value through net income: Accrued contingent consideration $ (2,396 ) $ (2,396 ) $ — $ — $ (2,396 ) Measured at fair value through comprehensive income: Cash equivalents (funds held for customers) 16,000 16,000 16,000 — — Available-for-sale debt securities (funds held for customers) 15,463 15,463 — 15,463 — Amortized cost: Cash 59,740 59,740 59,740 — — Cash (funds held for customers) 69,519 69,519 69,519 — — Loans and notes receivable from Safeguard distributors 81,560 60,795 — — 60,795 Long-term debt (1) 910,000 910,000 — 910,000 — (1) Amounts exclude capital lease obligations.

Restructuring and Related Activities [Abstract]
Restructuring and integration expense	Restructuring and integration expense Net restructuring and integration expense for the years ended December 31 consisted of the following components: (dollars in thousands) 2018 2017 2016 Severance accruals $ 7,672 $ 7,843 $ 7,217 Severance reversals (1,898 ) (667 ) (864 ) Operating lease obligations 597 23 59 Operating lease reversals (71 ) — — Net accruals 6,300 7,199 6,412 Other costs 14,903 1,931 1,359 Restructuring and integration expense $ 21,203 $ 9,130 $ 7,771 Number of employees included in severance accruals 205 200 265 Net restructuring and integration expense for the years ended December 31 is reflected in the consolidated statements of income as follows: (in thousands) 2018 2017 2016 Total cost of revenue $ 1,466 $ 568 $ 647 Operating expenses 19,737 8,562 7,124 Restructuring and integration expense $ 21,203 $ 9,130 $ 7,771 In each of the past 3 years, the net accruals included severance charges related to employee reductions across functional areas as we continued to reduce costs, primarily within our sales and marketing, information technology and fulfillment functions, as well as employee reductions related to our integration initiatives. These charges were reduced by the reversal of accruals when fewer employees received severance benefits than originally estimated. Other restructuring and integration costs, which were expensed as incurred, included items such as information technology costs, employee and equipment moves, training and travel. During 2018, these costs related primarily to the integration of acquired businesses and the consolidation of information technology systems. Restructuring and integration accruals of $3,461 as of December 31, 2018 are reflected in the consolidated balance sheet as accrued liabilities of $3,320 and other non-current liabilities of $141 . Restructuring and integration accruals of $4,380 as of December 31, 2017 are included in accrued liabilities in the consolidated balance sheet. The majority of the employee reductions are expected to be completed by mid-2019, and we expect most of the related severance payments to be paid by the third quarter of 2019, utilizing cash from operations. The remaining amounts due under operating lease obligations will be paid by December 2020. As of December 31, 2018 , approximately 30 employees had not yet started to receive severance benefits.

CEO transition costs [Abstract]
CEO transition costs [Text Block]	Chief Executive Officer transition costs In April 2018, we announced the retirement of Lee Schram, our former Chief Executive Officer (CEO). Mr. Schram will remain employed under the terms of a transition agreement through March 1, 2019. Under the terms of the transition agreement, if Mr. Schram remains employed through March 1, 2019, assists with the CEO transition, and complies with certain covenants, we will provide to Mr. Schram certain benefits, including a transition bonus in the amount of $2,000 , accelerated vesting of certain restricted stock unit awards and continued vesting and settlement of a pro-rata portion of outstanding performance share awards to the extent such awards were earned based on the attainment of performance goals. The modifications to Mr. Schram's share-based payment awards resulted in expense of $2,088 , which is being recognized through the first quarter of 2019. In conjunction with the CEO transition, we also offered retention agreements to certain members of our management team under which each employee will be entitled to receive a cash bonus equal to his or her annual base salary or up to 1.5 times his or her annual base salary if he or she remains employed during the retention period, generally from July 1, 2018 to December 31, 2019, and complies with certain covenants. The retention bonus will be paid to an employee if his or her employment is terminated without cause before the end of the retention period. In addition, we incurred certain other costs related to the CEO transition process, such as executive search, legal, travel and board of directors fees. CEO transition costs are included in SG&A expense and were $7,210 for the year ended December 31, 2018 , including the impact of modifications to Mr. Schram’s share-based payment awards. Accruals for CEO transition costs were $1,972 within accrued liabilities and $1,808

Income tax provision	Income tax provision Income before income taxes was comprised of the following for the years ended December 31: (in thousands) 2018 2017 2016 United States $ 198,727 $ 299,424 $ 325,396 Foreign 13,904 13,403 14,990 Income before income taxes $ 212,631 $ 312,827 $ 340,386 The components of the income tax provision were as follows for the years ended December 31: (in thousands) 2018 2017 2016 Current tax provision: Federal $ 57,117 $ 104,079 $ 93,261 State 11,319 12,996 12,006 Foreign 5,921 4,774 3,851 Total current tax provision 74,357 121,849 109,118 Deferred tax provision: Federal (7,220 ) (37,471 ) 1,752 State (1,701 ) (491 ) 462 Foreign (2,435 ) (1,215 ) (328 ) Total deferred tax provision (11,356 ) (39,177 ) 1,886 Income tax provision $ 63,001 $ 82,672 $ 111,004 The effective tax rate on pre-tax income reconciles to the United States federal statutory tax rate for the years ended December 31 as follows: 2018 2017 2016 Income tax at federal statutory rate 21.0 % 35.0 % 35.0 % Goodwill impairment charge 7.1 % 1.5 % — State income tax expense, net of federal income tax benefit 3.0 % 2.7 % 2.4 % Impact of Tax Cuts and Jobs Act (0.8 %) (6.6 %) — Qualified production activities deduction — (3.2 %) (2.8 %) Net tax benefit of share-based compensation (0.8 %) (1.6 %) (1.2 %) Other 0.1 % (1.4 %) (0.8 %) Effective tax rate 29.6 % 26.4 % 32.6 % In December 2017, United States tax reform was signed into law as the Tax Cuts and Jobs Act (the 2017 Tax Act). This legislation included a broad range of tax reforms, including changes to corporate tax rates, business deductions and international tax provisions. The tax effects of changes in tax laws or rates must be recognized in the period in which the law is enacted. As such, this legislation resulted in a net benefit of approximately $20,500 to our 2017 income tax provision. This amount included the net tax benefit from the remeasurement of deferred income taxes to the new federal statutory tax rate of 21% , which was effective for us on January 1, 2018, and revised state income tax rates for those states we expected to follow the provisions of the 2017 Tax Act, partially offset by the establishment of a liability for repatriation toll charges related to undistributed foreign earnings and profits. During 2017, reasonable estimates were used to determine certain impacts of the 2017 Tax Act, including our 2017 deferred activity and the amount of post-1986 foreign deferred earnings subject to the repatriation toll charge. We finalized our accounting for the 2017 Tax Act during the fourth quarter of 2018. Our income tax provision for the year ended December 31, 2018 was reduced $1,700 for adjustments to our accounting for the 2017 Tax Act, primarily a reduction in the amount accrued for the repatriation toll charge. A reconciliation of the beginning and ending amount of unrecognized tax benefits, excluding accrued interest and penalties and the federal benefit of deductible state income tax, is as follows: (in thousands) 2018 2017 2016 Balance, beginning of year $ 3,795 $ 7,373 $ 5,743 Additions for tax positions of current year 315 378 521 Additions for tax positions of prior years 1,177 659 1,428 Reductions for tax positions of prior years (108 ) (4,389 ) (177 ) Lapse of statutes of limitations (378 ) (226 ) (142 ) Balance, end of year $ 4,801 $ 3,795 $ 7,373 If the unrecognized tax benefits as of December 31, 2018 were recognized in our consolidated financial statements, income tax expense would decrease $4,801 . Accruals for interest and penalties, excluding the tax benefits of deductible interest, were $1,156 as of December 31, 2018 and $1,046 as of December 31, 2017 . Our income tax provision included expense for interest and penalties of $110 in 2018 and $179 in 2016 and included a reduction for interest and penalties of $284 in 2017 . Within the next 12 months, it is reasonably possible that our unrecognized tax benefits will change in the range of a decrease of $3,200 to an increase of $1,800 as we attempt to resolve certain federal and state tax matters or as federal and state statutes of limitations expire. Due to the nature of the underlying liabilities and the extended time frame often needed to resolve income tax uncertainties, we cannot provide reliable estimates of the amount or timing of cash payments that may be required to settle these liabilities. The statute of limitations for federal tax assessments for 2014 and prior years has expired. Audits of our federal income tax returns through 2015 have been completed by the Internal Revenue Service (IRS). Our 2016 and 2017 returns and our 2018 return, when filed, are subject to IRS examination. In general, income tax returns for the years 2014 through 2018 remain subject to examination by foreign, state and city tax jurisdictions. In the event that we have determined not to file income tax returns with a particular state or city, all years remain subject to examination by the tax jurisdiction. The ultimate outcome of tax matters may differ from our estimates and assumptions. Unfavorable settlement of any particular issue would require the use of cash and could result in increased income tax expense. Favorable resolution would result in reduced income tax expense. Tax-effected temporary differences that gave rise to deferred tax assets and liabilities as of December 31 were as follows: 2018 2017 (in thousands) Deferred tax assets Deferred tax liabilities Deferred tax assets Deferred tax liabilities Goodwill $ — $ 47,993 $ — $ 45,317 Intangible assets — 3,780 — 7,490 Prepaid assets — 3,469 — 3,137 Installment sales treatment of notes receivable — 3,054 — 2,450 Deferred advertising costs — 1,948 — 1,920 Property, plant and equipment — 1,739 — 8,122 Net operating loss, capital loss and tax credit carryforwards 9,380 — 11,802 — Reserves and accruals 8,893 — 6,151 — Inventories 2,043 — 2,110 — All other 4,657 5,095 3,895 3,119 Total deferred taxes 24,973 67,078 23,958 71,555 Valuation allowances (1,689 ) — (1,518 ) — Net deferred taxes $ 23,284 $ 67,078 $ 22,440 $ 71,555 The valuation allowances as of December 31, 2018 and December 31, 2017 related primarily to capital loss carryforwards in Canada and net operating loss carryforwards in various state jurisdictions that we do not currently expect to fully realize. The provision for income taxes included benefits of $290 for 2018 , $1,015 for 2017 and $302 for 2016 related to changes in the valuation allowances. The remainder of the change in the valuation allowances was attributable to foreign currency translation. As of December 31, 2018 , deferred income taxes have not been recognized on unremitted earnings of our foreign subsidiaries, as these amounts are intended to be reinvested indefinitely in the operations of those subsidiaries. If we were to repatriate all of our foreign cash and cash equivalents into the United States at one time, the tax effects would generally be limited to foreign withholding taxes on any distributions. As of December 31, 2018 , the amount of cash and cash equivalents held by our foreign subsidiaries was $51,310 , primarily in Canada. As of December 31, 2018 , we had the following net operating loss, capital loss and tax credit carryforwards: • state net operating loss carryforwards and tax credit carryforwards of $56,713 that expire at various dates up to 2038, • foreign capital loss and net operating loss carryforwards of $6,733 that do not expire, • foreign research tax credit and net operating loss carryforwards of $6,238 that expire at various dates up to 2037, and • federal net operating loss and capital loss carryforwards of $1,708

Share-based Compensation [Abstract]
Share-based compensation plans	Share-based compensation plans Our employee share-based compensation plans consist of our employee stock purchase plan and our long-term incentive plan. Effective May 2, 2017, our shareholders approved the Deluxe Corporation 2017 Long-Term Incentive Plan, simultaneously terminating our previous plan. Under this plan, 5.0 million shares of common stock plus any shares released as a result of the forfeiture or termination of awards issued under our prior plan are reserved for issuance, with 5.4 million shares remaining available for issuance as of December 31, 2018 . Full value awards such as restricted stock, restricted stock units and performance share awards reduce the number of shares available for issuance by a factor of 2.23 , or if such an award were forfeited or terminated without delivery of the shares, the number of shares that again become eligible for issuance would be multiplied by a factor of 2.23 . Under our current and previous plans, we have granted non-qualified stock options, restricted stock units, restricted shares and performance share awards. Our current plan also allows for the issuance of stock appreciation rights, which we have not granted as of December 31, 2018 . Our policies regarding the recognition of compensation expense for employee share-based awards can be found in Note 1. The following amounts were recognized in our consolidated statements of income for share-based compensation awards for the years ended December 31: (in thousands) 2018 2017 2016 Restricted shares and restricted stock units $ 5,232 $ 6,533 $ 5,786 Performance share awards 4,502 4,782 2,806 Stock options 3,143 3,270 3,401 Employee stock purchase plan 501 524 466 Total share-based compensation expense $ 13,378 $ 15,109 $ 12,459 Income tax benefit $ (3,946 ) $ (5,152 ) $ (4,063 ) As of December 31, 2018 , the total compensation expense for unvested awards not yet recognized in our consolidated statements of income was $16,683 , net of the effect of estimated forfeitures. This amount is expected to be recognized over a weighted-average period of 2.1 years. Non-qualified stock options – All options allow for the purchase of shares of common stock at prices equal to the stock's market value at the date of grant. Options become exercisable beginning 1 year after the grant date, with one-third vesting each year over 3 years. Options may be exercised up to 7 years following the date of grant. Beginning 1 year after the grant date, in the case of qualified retirement, death or disability, options vest immediately and the period over which the options can be exercised is shortened. Beginning 1 year after the grant date, in the case of involuntary termination without cause, a pro-rata portion of the options vest immediately and the period over which the options can be exercised is shortened. Employees forfeit unvested options when they voluntarily terminate their employment with the company, and they have up to 3 months to exercise vested options before they are canceled. In the case of involuntary termination with cause, the entire unexercised portion of the award is canceled. All options may vest immediately upon a change of control, as defined in the award agreement. The following weighted-average assumptions were used in the Black-Scholes option pricing model in determining the fair value of stock options granted: 2018 2017 2016 Risk-free interest rate 2.7 % 1.6 % 1.1 % Dividend yield 2.0 % 1.6 % 2.2 % Expected volatility 23.0 % 23.7 % 25.5 % Weighted-average option life (in years) 3.9 3.7 4.0 The risk-free interest rate for periods within the expected option life is based on the United States Treasury yield curve in effect at the grant date. The dividend yield is estimated over the expected life of the option based on historical dividends paid. Expected volatility is based on the historical volatility of our stock over the most recent historical period equivalent to the expected life of the option. The expected life is the average length of time over which we expect the employee groups will exercise their options, based on historical experience with similar grants. Each option is convertible into 1 share of common stock upon exercise. Information regarding options issued under the current and all previous plans was as follows: Number of options (in thousands) Weighted-average exercise price per option Aggregate intrinsic value (in thousands) Weighted-average remaining contractual term (in years) Outstanding, December 31, 2015 1,354 $ 40.11 Granted 458 54.44 Exercised (476 ) 30.80 Forfeited or expired (85 ) 58.06 Outstanding, December 31, 2016 1,251 47.68 Granted 270 75.30 Exercised (347 ) 38.72 Forfeited or expired (35 ) 62.19 Outstanding, December 31, 2017 1,139 56.51 Granted 519 62.12 Exercised (339 ) 42.55 Forfeited or expired (74 ) 66.85 Outstanding, December 31, 2018 1,245 62.04 $ 127 5.0 Exercisable at December 31, 2016 624 $ 38.50 Exercisable at December 31, 2017 555 47.42 Exercisable at December 31, 2018 472 59.90 $ 127 3.5 The weighted-average grant-date fair value of options granted was $10.98 per option for 2018 , $12.81 per option for 2017 and $9.16 per option for 2016 . The intrinsic value of a stock award is the amount by which the fair value of the underlying stock exceeds the exercise price of the award. The total intrinsic value of options exercised was $10,007 for 2018 , $11,699 for 2017 and $16,043 for 2016 . Restricted stock units – Certain management employees have the option to receive a portion of their bonus payment in the form of restricted stock units. When employees elect this payment method, we provide an additional matching amount of restricted stock units equal to 50% of the restricted stock units earned under the bonus plan. These awards vest 2 years from the date of grant. In the case of qualified retirement, death, disability or change of control, the units vest immediately. In the case of involuntary termination without cause or voluntary termination, employees receive a cash payment for the units earned under the bonus plan, but forfeit the company-provided matching amount. In addition to awards granted to employees, non-employee members of our board of directors can elect to receive all or a portion of their fees in the form of restricted stock units. Directors are issued shares in exchange for the units upon the earlier of the tenth anniversary of February 1 st of the year following the year in which the non-employee director ceases to serve on the board or such other objectively determinable date pre-elected by the director. Each restricted stock unit is convertible into 1 share of common stock upon completion of the vesting period. Information regarding our restricted stock units was as follows: Number of units (in thousands) Weighted-average grant date fair value per unit Weighted-average remaining contractual term (in years) Outstanding at December 31, 2015 167 $ 34.74 Granted 38 55.39 Vested (46 ) 40.15 Forfeited (20 ) 58.69 Outstanding at December 31, 2016 139 37.99 Granted 16 73.27 Vested (43 ) 43.18 Forfeited (3 ) 57.18 Outstanding at December 31, 2017 109 38.31 Granted 110 52.32 Vested (22 ) 48.14 Forfeited (2 ) 74.96 Outstanding at December 31, 2018 195 45.41 3.3 Of the awards outstanding as of December 31, 2018 , 14 thousand restricted stock units with a value of $546 were included in accrued liabilities and other non-current liabilities in our consolidated balance sheet. As of December 31, 2018 , these units had a fair value of $38.44 per unit and a weighted-average remaining contractual term of 7 months. The total fair value of restricted stock units that vested was $1,619 for 2018 , $3,161 for 2017 and $2,805 for 2016 . We made cash payments of $78 during 2018 , $421 during 2017 and $140 during 2016 to settle share-based liabilities. Restricted shares – For restricted share awards granted to employees under our current long-term incentive plan, one-third of the shares vest each year over 3 years. Such awards granted under our previous plan vest in their entirety at the end of the 3 year vesting period. Restricted shares granted to directors typically have a 1 year vesting period. The restrictions lapse immediately in the case of qualified retirement, death or disability, or in the event of a change in control where replacement securities are not awarded. In the case of involuntary termination without cause, restrictions on a pro-rata portion of the shares lapse based on how much of the vesting period has passed. In the case of voluntary termination of employment or termination with cause, the unvested restricted shares are forfeited. Information regarding unvested restricted shares was as follows: Number of shares (in thousands) Weighted-average grant date fair value per share Weighted-average remaining contractual term (in years) Unvested at December 31, 2015 170 $ 56.35 Granted 97 56.22 Vested (22 ) 56.63 Forfeited (25 ) 56.86 Unvested at December 31, 2016 220 56.43 Granted 68 74.84 Vested (99 ) 52.41 Forfeited (8 ) 61.37 Unvested at December 31, 2017 181 65.33 Granted 77 71.29 Vested (76 ) 69.73 Forfeited (14 ) 66.24 Unvested at December 31, 2018 168 66.02 1.1 The total fair value of restricted shares that vested was $5,375 for 2018 , $7,452 for 2017 and $1,398 for 2016 . Performance share awards – Our performance share awards have a 3 -year vesting period. Shares will be issued at the end of the vesting period if performance targets relating to revenue and total shareholder return are achieved. If employment is terminated for any reason prior to the 1 -year anniversary of the commencement of the performance period, the award is forfeited. On or after the 1 -year anniversary of the commencement of the performance period, a pro-rata portion of the shares awarded at the end of the performance period would be issued in the case of qualified retirement, death, disability, involuntary termination without cause or resignation for good reason, as defined in the agreement. The following weighted-average assumptions were used in the Monte Carlo simulation model in determining the fair value of market-based performance shares granted: 2018 2017 2016 Risk-free interest rate 2.4 % 1.4 % 0.9 % Dividend yield 1.6 % 1.7 % 2.3 % Expected volatility 21.6 % 21.9 % 22.7 % The risk-free interest rate for periods within the expected award life is based on the United States Treasury yield curve in effect at the grant date. The dividend yield is estimated over the expected life of the award based on historical dividends paid. Expected volatility is based on the historical volatility of our stock. Information regarding unvested performance shares was as follows: Performance shares (in thousands) Weighted-average grant date fair value per share Weighted-average remaining contractual term (in years) Unvested at December 31, 2015 122 $ 58.13 Granted (1) 153 52.75 Forfeited (39 ) 55.04 Unvested at December 31, 2016 236 55.15 Granted (1) 83 75.31 Forfeited (9 ) 64.85 Vested (60 ) 50.17 Adjustment for performance results achieved (2) 5 50.34 Unvested at December 31, 2017 255 63.42 Granted (1) 91 74.49 Forfeited (48 ) 59.32 Vested (45 ) 67.10 Adjustment for performance results achieved (2) (3 ) 67.11 Unvested at December 31, 2018 250 67.54 1.1 (1) Reflects awards granted assuming achievement of performance goals at target. (2) Reflects the difference between the awards earned at the end of the performance period and the target number of shares. Employee stock purchase plan – During 2018 , 53 thousand shares were issued under this plan at prices of $63.13 and $50.09 . During 2017 , 46 thousand shares were issued under this plan at prices of $61.92 and $61.37 . During 2016 , 48 thousand shares were issued under this plan at prices of $47.52 and $57.45

Compensation Related Costs [Abstract]
Employee compensation plans	Employee compensation plans Profit sharing/401(k) plan – We maintain a profit sharing/401(k) plan to provide retirement benefits for certain employees. The plan covers a majority of our full-time employees, as well as some part-time employees. Employees are eligible to participate in the plan on the first day of the quarter following their first full year of service. Profit sharing contributions are made solely by Deluxe and are remitted to the plan's trustee. These contributions vary based on the company's performance. 401(k) contributions are made by both employees and Deluxe. Employees may contribute up to 50% of eligible wages, subject to IRS limitations and the terms and conditions of the plan. For the majority of employees, we match 100% of the first 1% of wages contributed and 50% of the next 5% of wages contributed, beginning on the first day of the quarter following an employee's first full year of service. All employee and employer contributions are remitted to the plan's trustee. Benefits provided by the plan are paid from accumulated funds of the trust. Employees are provided a broad range of investment options to choose from when investing their profit sharing/401(k) plan funds. Investing in our common stock is not one of these options, although funds selected by employees may at times hold our common stock. Cash bonus programs – We provide short-term cash bonus programs under which employees may receive cash bonus payments based on our performance for a given fiscal year. Payments earned are paid directly to employees shortly after the end of the year. Expense recognized in the consolidated statements of income for these plans was as follows for the years ended December 31: (in thousands) 2018 2017 2016 Performance-based compensation plans (1) $ 20,297 $ 22,085 $ 19,730 401(k) expense 9,686 9,023 8,309 (1) Excludes expense for share-based compensation, which is discussed in Note 12. Deferred compensation plan – We have a non-qualified deferred compensation plan that allows eligible employees to defer a portion of their compensation. Participants can elect to defer up to 100% of their base salary plus up to 50% of their bonus for the year. The compensation deferred under this plan is credited with earnings or losses measured by the mirrored rate of return on phantom investments elected by plan participants, which are similar to the investments available for funds invested under our profit sharing/401(k) plan. Each participant is fully vested in all deferred compensation and earnings. A participant may elect to receive deferred amounts in a lump-sum payment or in monthly installments upon termination of employment or disability. Our total liability under this plan was $4,458 as of December 31, 2018 and $4,581 as of December 31, 2017 . These amounts are reflected in accrued liabilities and other non-current liabilities in the consolidated balance sheets. We hold investments in an irrevocable rabbi trust for our deferred compensation plan. These assets consist of investments in company-owned life insurance policies, which are included in long-term investments in the consolidated balance sheets, and totaled $10,831 as of December 31, 2018 and $11,648 as of December 31, 2017

Postretirement benefits

Defined Benefit Plan [Abstract]
Postretirement benefits	Postretirement benefits We have historically provided certain health care benefits for a large number of retired United States employees. Employees hired prior to January 1, 2002 become eligible for benefits if they attain the appropriate years of service and age prior to retirement. Employees hired on January 1, 2002 or later are not eligible to participate in our retiree health care plan. In addition to our retiree health care plan, we also have a supplemental executive retirement plan (SERP) in the United States. The SERP is no longer an active plan. It is not adding new participants and all of the current participants are retired. The SERP has no plan assets, but our obligation is fully funded by investments in company-owned life insurance policies. Obligations and funded status – The following tables summarize the change in benefit obligation, plan assets and funded status during 2018 and 2017 : (in thousands) Postretirement benefit plan Pension plan (1) Change in benefit obligation: Benefit obligation, December 31, 2016 $ 94,188 $ 3,447 Interest cost 2,794 101 Net actuarial (gain) loss (1,469 ) 174 Benefits paid from plan assets and company funds (7,919 ) (324 ) Benefit obligation, December 31, 2017 87,594 3,398 Interest cost 2,529 97 Net actuarial gain (9,231 ) (23 ) Benefits paid from plan assets and company funds (7,175 ) (324 ) Benefit obligation, December 31, 2018 $ 73,717 $ 3,148 Change in plan assets: Fair value of plan assets, December 31, 2016 $ 118,128 $ — Return on plan assets 15,309 — Benefits paid (5,994 ) — Fair value of plan assets, December 31, 2017 127,443 — Return on plan assets (6,663 ) — Benefits paid (5,804 ) — Fair value of plan assets, December 31, 2018 $ 114,976 $ — Funded status, December 31, 2017 $ 39,849 $ (3,398 ) Funded status, December 31, 2018 $ 41,259 $ (3,148 ) (1) The accumulated benefit obligation equals the projected benefit obligation. The funded status of our plans was recognized in the consolidated balance sheets as of December 31 as follows: Postretirement benefit plan Pension plan (in thousands) 2018 2017 2018 2017 Other non-current assets $ 41,259 $ 39,849 $ — $ — Accrued liabilities — — 324 324 Other non-current liabilities — — 2,824 3,074 Amounts included in accumulated other comprehensive loss as of December 31 that have not been recognized as components of postretirement benefit income were as follows: (in thousands) 2018 2017 Unrecognized prior service credit $ 14,178 $ 15,599 Unrecognized net actuarial loss (57,436 ) (55,174 ) Tax effect 6,729 12,746 Amount recognized in accumulated other comprehensive loss, net of tax $ (36,529 ) $ (26,829 ) The unrecognized prior service credit relates to our postretirement benefit plan and is a result of previous plan amendments that reduced the accumulated postretirement benefit obligation. A reduction is first used to reduce any existing unrecognized prior service cost, then to reduce any remaining unrecognized transition obligation. The excess is the unrecognized prior service credit. The prior service credit is being amortized on the straight-line basis over a weighted-average period of 21 years . The amortization period for the prior service credit is the average remaining life expectancy of plan participants at the time of the plan amendment. Unrecognized net actuarial gains and losses result from experience different from that assumed and from changes in assumptions. The net actuarial gain generated during 2018 was primarily due to favorable claims experience and an increase in the discount rate used to discount the benefit obligation. The net actuarial gain generated during 2017 was primarily due to favorable claims experience, partially offset by a decrease in the discount rate used to discount the benefit obligation. Unrecognized actuarial gains and losses for our postretirement benefit plan are being amortized over the average remaining life expectancy of inactive plan participants, as a large percentage of the plan participants are classified as inactive. This amortization period is currently 14.3 years . Postretirement benefit income – Postretirement benefit income for the years ended December 31 consisted of the following components: (in thousands) 2018 2017 2016 Interest cost $ 2,626 $ 2,896 $ 3,118 Expected return on plan assets (7,737 ) (7,128 ) (7,335 ) Amortization of prior service credit (1,421 ) (1,421 ) (1,421 ) Amortization of net actuarial losses 2,884 3,637 3,797 Net periodic benefit income $ (3,648 ) $ (2,016 ) $ (1,841 ) Actuarial assumptions – In measuring benefit obligations as of December 31, the following discount rate assumptions were used: Postretirement benefit plan Pension plan 2018 2017 2018 2017 Discount rate 4.13 % 3.46 % 4.01 % 3.35 % In measuring net periodic benefit income for the years ended December 31, the following assumptions were used: Postretirement benefit plan Pension plan 2018 2017 2016 2018 2017 2016 Discount rate 3.46 % 3.81 % 4.02 % 3.35 % 3.66 % 3.88 % Expected return on plan assets 6.25 % 6.25 % 6.50 % — — — The discount rate assumption is based on the rates of return on high-quality, fixed-income instruments currently available whose cash flows approximate the timing and amount of expected benefit payments. Effective December 31, 2015, we changed the method we use to determine the discount rate used in calculating the interest component of net periodic benefit income. Instead of using a single weighted-average discount rate, we elected to utilize a full yield curve approach by applying separate discount rates to each future projected benefit payment based on time until payment. We made this change to provide a more precise measurement of interest costs by improving the correlation between projected cash flows and the corresponding yield curve rates. This change did not affect the measurement of our total benefit obligation, but it reduced the interest component of net periodic benefit income by $881 in 2016. This is a change in accounting estimate, and accordingly, we accounted for it on a prospective basis. In determining the expected long-term rate of return on plan assets, we utilize our historical returns and then adjust these returns for estimated inflation and projected market returns. Our inflation assumption is primarily based on analysis of historical inflation data. In measuring benefit obligations as of December 31 for our postretirement benefit plan, the following assumptions for health care cost trend rates were used: 2018 2017 2016 Participants under age 65 Participants age 65 and older Participants under age 65 Participants age 65 and older Participants under age 65 Participants age 65 and older Health care cost trend rate assumed for next year 7.70 % 8.70 % 7.90 % 9.10 % 7.50 % 8.75 % Rate to which the cost trend rate is assumed to decline (the ultimate trend rate) 4.50 % 4.50 % 4.50 % 4.50 % 4.50 % 4.50 % Year that the rate reaches the ultimate trend rate 2029 2029 2025 2025 2025 2025 Plan assets – The allocation of plan assets by asset category as of December 31 was as follows: Postretirement benefit plan 2018 2017 Mortgage-backed securities 25 % 23 % U.S. large capitalization equity securities 23 % 24 % U.S. corporate debt securities 20 % 18 % International equity securities 18 % 18 % Government debt securities 11 % 13 % U.S. small and mid-capitalization equity securities 3 % 4 % Total 100 % 100 % Our postretirement benefit plan has assets that are intended to meet long-term obligations. In order to meet these obligations, we employ a total return investment approach that considers cash flow needs and balances long-term projected returns against expected asset risk, as measured using projected standard deviations. Risk tolerance is established through consideration of projected plan liabilities, the plan's funded status, projected liquidity needs and current corporate financial condition. The target asset allocation percentages for our postretirement benefit plan are based on our liability and asset projections. The targeted allocation of plan assets is 55% fixed income securities, 24% large capitalization equity securities, 18% international equity securities and 3% small and mid-capitalization equity securities. Information regarding fair value measurements of plan assets was as follows as of December 31, 2018 : Fair value measurements using Quoted prices in active markets for identical assets Significant other observable inputs Significant unobservable inputs Investments measured at net asset value Fair value as of December 31, 2018 (in thousands) (Level 1) (Level 2) (Level 3) Mortgage-backed securities $ — $ 13,593 $ — $ 15,138 $ 28,731 U.S. large capitalization equity securities — — — 26,240 26,240 U.S. corporate debt securities 6,489 12,468 — 3,594 22,551 International equity securities 20,261 298 — — 20,559 Government debt securities — 12,738 — — 12,738 U.S. small and mid-capitalization equity securities 3,259 27 — 551 3,837 Other debt securities (6 ) 326 — — 320 Plan assets $ 30,003 $ 39,450 $ — $ 45,523 $ 114,976 Information regarding fair value measurements of plan assets was as follows as of December 31, 2017 : Fair value measurements using Quoted prices in active markets for identical assets Significant other observable inputs Significant unobservable inputs Investments measured at net asset value Fair value as of December 31, 2017 (in thousands) (Level 1) (Level 2) (Level 3) Mortgage-backed securities $ — $ 13,274 $ — $ 15,388 $ 28,662 U.S. large capitalization equity securities — — — 30,167 30,167 U.S. corporate debt securities — 13,032 — 10,206 23,238 International equity securities 23,127 340 — — 23,467 Government debt securities — 17,118 — — 17,118 U.S. small and mid-capitalization equity securities 3,490 56 — 956 4,502 Other debt securities 134 155 — — 289 Plan assets $ 26,751 $ 43,975 $ — $ 56,717 $ 127,443 The fair value of Level 2 mortgage-backed securities is estimated using pricing models with inputs derived principally from observable market data. The fair value of our other Level 2 debt securities is typically estimated using pricing models, quoted prices of securities with similar characteristics or discounted cash flow calculations that maximize observable inputs, such as current yields for similar instruments adjusted for trades and other pertinent market information. Our policy is to recognize transfers between fair value levels as of the end of the reporting period in which the transfer occurred. Cash flows – We made no contributions to plan assets during the past 3 years. We have fully funded the United States SERP obligation with investments in company-owned life insurance policies. The cash surrender value of these policies is included in long-term investments in the consolidated balance sheets and totaled $6,869 as of December 31, 2018 and $6,615 as of December 31, 2017 . The following benefit payments are expected to be paid during the years indicated: (in thousands) Postretirement benefit plan Pension plan 2019 $ 7,679 $ 320 2020 7,906 320 2021 7,730 310 2022 7,219 300 2023 6,686 300 2024 - 2028 26,205 1,320

Debt and lease obligations [Abstract]
Debt and lease obligations	Debt and lease obligations Debt outstanding was comprised of the following at December 31: (in thousands) 2018 2017 Amount drawn on revolving credit facility $ 910,000 $ 413,000 Amount outstanding under term loan facility — 294,938 Capital lease obligations 1,864 1,914 Long-term debt, principal amount 911,864 709,852 Less unamortized debt issuance costs — (471 ) Less current portion of long-term debt (791 ) (44,121 ) Long-term debt 911,073 665,260 Current portion of amount drawn under term loan facility — 43,313 Current portion of capital lease obligations 791 808 Long-term debt due within one year, principal amount 791 44,121 Less unamortized debt issuance costs — (81 ) Long-term debt due within one year 791 44,040 Total debt $ 911,864 $ 709,300 There are currently no limitations on the amount of dividends and share repurchases under the terms of our credit agreement. However, if our leverage ratio, defined as total debt less unrestricted cash to EBITDA, should exceed 2.75 to 1, there would be an annual limitation on the amount of dividends and share repurchases. Senior notes – In November 2012, we issued $200,000 of 6.0% senior notes that were scheduled to mature on November 15, 2020 . The notes were issued via a private placement under Rule 144A of the Securities Act of 1933 and were subsequently registered with the SEC via a registration statement that became effective on April 3, 2013. In November 2016, we retired all of these notes, realizing a loss on early debt extinguishment of $7,858 during 2016, consisting of a contractual call premium and the write-off of related debt issuance costs. This retirement was funded utilizing a new term loan facility established under our credit facility agreement. As discussed in Note 7, we entered into interest rate swaps to hedge these notes. The swaps were terminated in November 2016 at the time of the debt redemption. The cumulative decrease in the fair value of hedged debt as of the date of the termination of $2,842 was recorded as interest expense in the 2016 consolidated statement of income. Credit facility – In March 2018, we entered into a revolving credit facility in the amount of $950,000 , subject to increase under the credit agreement to an aggregate amount not exceeding $1,425,000 . The credit facility matures in March 2023. Our previous credit facility agreement was terminated contemporaneously with our entry into the new credit facility and was repaid utilizing proceeds from the new credit facility. Our quarterly commitment fee ranges from 0.175% to 0.35% based on our leverage ratio. As of December 31, 2018 , $910,000 was drawn on our revolving credit facility at a weighted-average interest rate of 3.79% . As of December 31, 2017 , $413,000 was drawn on our previous revolving credit facility at a weighted-average interest rate of 2.98% . Our previous credit facility agreement also included a $330,000 variable rate term loan facility, the proceeds from which were used to retire our senior notes due in 2020 and to partially fund the acquisition of FMCG in December 2016 (Note 6). As of December 31, 2017 , $294,938 was outstanding under the term loan facility at a weighted-average interest rate of 2.99% . This amount was repaid in March 2018, utilizing proceeds from the new revolving credit facility. Borrowings under the credit agreement are collateralized by substantially all of our personal and intangible property. The credit agreement governing our credit facility contains customary covenants regarding limits on levels of subsidiary indebtedness and capital expenditures, liens, investments, acquisitions, certain mergers, certain asset sales outside the ordinary course of business, and change in control as defined in the agreement. The agreement also requires us to maintain certain financial ratios, including a maximum leverage ratio of 3.5 and a minimum ratio of consolidated earnings before interest and taxes to consolidated interest expense, as defined in the credit agreement, of 3.0 . Daily average amounts outstanding under our credit facility were as follows for the years ended December 31: (in thousands) 2018 2017 2016 Revolving credit facility: Daily average amount outstanding $ 731,110 $ 436,588 $ 417,219 Weighted-average interest rate 3.24 % 2.55 % 1.93 % Term loan facility: Daily average amount outstanding $ 63,638 $ 315,862 $ 52,381 Weighted-average interest rate 2.97 % 2.57 % 1.52 % As of December 31, 2018 , amounts were available for borrowing under our revolving credit facility as follows: (in thousands) Total available Revolving credit facility commitment (1) $ 950,000 Amount drawn on revolving credit facility (910,000 ) Outstanding letters of credit (2) (10,221 ) Net available for borrowing as of December 31, 2018 $ 29,779 (1) In January 2019, we increased the credit facility by $200,000 , bringing the total availability to $1,150,000 . (2) We use standby letters of credit primarily to collateralize certain obligations related to our self-insured workers' compensation claims, as well as claims for environmental matters, as required by certain states. These letters of credit reduce the amount available for borrowing under our revolving credit facility. Lease obligations – We had capital lease obligations of $1,864 as of December 31, 2018 and $1,914 as of December 31, 2017 related to information technology hardware. The lease obligations will be paid through October 2022 . The related assets are included in property, plant and equipment in the consolidated balance sheets. Depreciation of the leased assets is included in depreciation expense in the consolidated statements of cash flows. A portion of the leased assets have not yet been placed in service. The balance of those leased assets placed in service as of December 31 was as follows: (in thousands) 2018 2017 Machinery and equipment $ 6,413 $ 4,676 Accumulated depreciation (4,673 ) (3,522 ) Net assets under capital leases $ 1,740 $ 1,154 In addition to capital leases, we also have operating leases on certain facilities and equipment. Rental expense was $23,928 for 2018 , $19,839 for 2017 and $16,454 for 2016 . As of December 31, 2018 , future minimum lease payments under our capital lease obligations and noncancelable operating leases with terms in excess of one year were as follows: (in thousands) Capital lease obligations Operating lease obligations 2019 $ 822 $ 16,479 2020 637 13,240 2021 365 9,001 2022 91 5,792 2023 — 3,263 Thereafter — 11,056 Total minimum lease payments 1,915 $ 58,831 Less portion representing interest (51 ) Present value of minimum lease payments $ 1,864

Other commitments and contingen

Other commitments and contingencies	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Other commitments and contingencies	Other commitments and contingencies Indemnifications – In the normal course of business, we periodically enter into agreements that incorporate general indemnification language. These indemnification provisions generally encompass third-party claims arising from our products and services, including, without limitation, service failures, breach of security, intellectual property rights, governmental regulations and/or employment-related matters. Performance under these indemnities would generally be triggered by our breach of the terms of the contract. In disposing of assets or businesses, we often provide representations, warranties and/or indemnities to cover various risks including, for example, unknown damage to the assets, environmental risks involved in the sale of real estate, liability to investigate and remediate environmental contamination at waste disposal sites and manufacturing facilities, and unidentified tax liabilities and legal matters related to periods prior to disposition. We do not have the ability to estimate the potential liability from such indemnities because they relate to unknown conditions. However, we do not believe that any liability under these indemnities would have a material adverse effect on our financial position, annual results of operations or annual cash flows. We have recorded liabilities for known indemnifications related to environmental matters. Environmental matters – We are currently involved in environmental compliance, investigation and remediation activities at some of our former sites, primarily printing facilities of our Financial Services and Small Business Services segments that have been sold. Remediation costs are accrued on an undiscounted basis when the obligations are either known or considered probable and can be reasonably estimated. Remediation or testing costs that result directly from the sale of an asset and which we would not have otherwise incurred are considered direct costs of the sale of the asset. As such, they are included in our measurement of the carrying value of the asset sold. Accruals for environmental matters were $2,755 as of December 31, 2018 and $2,646 as of December 31, 2017 . These accruals are included in accrued liabilities and other non-current liabilities in the consolidated balance sheets. Accrued costs consist of direct costs of the remediation activities, primarily fees that will be paid to outside engineering and consulting firms. Although recorded accruals include our best estimates, our total costs cannot be predicted with certainty due to various factors, such as the extent of corrective action that may be required, evolving environmental laws and regulations and advances in environmental technology. Where the available information is sufficient to estimate the amount of the liability, that estimate is used. Where the information is only sufficient to establish a range of probable liability and no point within the range is more likely than any other, the lower end of the range is recorded. We do not believe that the range of possible outcomes could have a material effect on our financial condition, results of operations or liquidity. Expense reflected in our consolidated statements of income for environmental matters was $750 for 2018 and $348 for 2017. The 2016 consolidated statement of income includes a net benefit from environmental matters of $1,692 . During the second quarter of 2016, we reversed a portion of the liability for one of our sold facilities as we determined that it was no longer probable that a portion of the estimated environmental remediation costs for this location would be incurred. We purchased an insurance policy during 2002 that covers up to $10,000 of third-party pollution claims through 2032 at certain owned, leased and divested sites. We also purchased an insurance policy during 2009 that covers up to $15,000 of third-party pollution claims through April 2019 at certain other sites. These policies cover liability for claims of bodily injury or property damage arising from pollution events at the covered facilities, as well as remediation coverage should we be required by a governing authority to perform remediation activities at the covered sites. No accruals have been recorded in our consolidated financial statements for any of the events contemplated in these insurance policies. We do not anticipate significant net cash outlays for environmental matters within the next 5 years. Self-insurance – We are self-insured for certain costs, primarily workers' compensation claims and medical and dental benefits for active employees and those employees on long-term disability. The liabilities associated with these items represent our best estimate of the ultimate obligations for reported claims plus those incurred, but not reported, and totaled $6,627 as of December 31, 2018 and $7,679 as of December 31, 2017 . These accruals are included in accrued liabilities and other non-current liabilities in the consolidated balance sheets. Our workers' compensation liability is recorded at present value. The difference between the discounted and undiscounted liability was not significant as of December 31, 2018 or December 31, 2017 . Our self-insurance liabilities are estimated, in part, by considering historical claims experience, demographic factors and other actuarial assumptions. The estimated accruals for these liabilities could be significantly affected if future events and claims differ from these assumptions and historical trends. Litigation – Recorded liabilities for legal matters, as well as related charges recorded in each of the past 3 years, were not material to our financial position, results of operations or liquidity during the periods presented, and we do not believe that any of the currently identified claims or litigation will materially affect our financial position, results of operations or liquidity upon resolution. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. If an unfavorable ruling were to occur, it may cause a material adverse impact on our financial position, results of operations or liquidity for the period in which the ruling occurs or in future periods.

Stockholders' Equity Note [Abstract]
Shareholders' equity	Shareholders’ equity In May 2016, our board of directors authorized the repurchase of up to $300,000 of our common stock, and in October 2018, the board increased our share repurchase authorization to $500,000 , inclusive of the remaining amount outstanding under the prior authorization. This authorization has no expiration date. During 2018, we repurchased 3.6 million shares for $200,000 under these authorizations. Under the May 2016 authorization and under a previous authorization, we repurchased 924 thousand shares for $65,000 during 2017 and we repurchased 901 thousand shares for $55,224 during 2016. As of December 31, 2018, $420,000 remained available for repurchase under the current authorization.

Long-lived assets of our foreign subsidiaries are located primarily in Australia and Canada and are not significant to our consolidated financial position. The accounting policies of the segments are the same as those described in Note 1. We allocate corporate costs for our shared services functions to our business segments, including costs of our executive management, human resources, supply chain, real estate, finance, information technology and legal functions. Where costs incurred are directly attributable to a business segment, those costs are charged directly to that segment. During 2017 and 2016, costs that were not directly attributable to a business segment were allocated to the segments based on segment revenue. Effective January 1, 2018, we completed a more detailed analysis of our corporate costs and were able to allocate substantially all of the costs directly to our business segments. The costs that were not directly allocated to a business segment, primarily certain human resources costs, were allocated to the segments based on the number of employees in each segment. This change in our allocation methodology did not have a significant impact on the operating results of our business segments. Corporate assets are not allocated to the segments and consisted primarily of long-term investments and assets related to our corporate shared services functions of manufacturing, information technology and real estate, including property, plant and equipment; internal-use software; and inventories and supplies. Depreciation and amortization expense related to corporate assets, which was allocated to the segments, was $33,812 in 2018 , $33,302 in 2017 and $32,785 in 2016 . We are an integrated enterprise, characterized by substantial intersegment cooperation, cost allocations and the sharing of assets. Therefore, we do not represent that these segments, if operated independently, would report the operating income and other financial information shown.

In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Restricted Cash . This standard requires the statement of cash flows to explain the change during the period in the total of cash, cash equivalents, restricted cash and restricted cash equivalents. This standard was effective for us on January 1, 2018 and must be applied retrospectively. During the quarter ended December 31, 2018, we identified a misstatement in our statement of cash flows presentation under this standard. We concluded that the cash and cash equivalents included in funds held for customers should be included with cash, cash equivalents, restricted cash and restricted cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statements of cash flows, in accordance with ASU No. 2016-18. Additionally, we determined that gross redemptions and purchases of marketable debt securities included in funds held for customers should be presented as cash flows from investing activities in the statements of cash flows. This misstatement affected our consolidated statements of cash flows as presented in our 2018 Quarterly Reports on Form 10-Q. We assessed the materiality of this misstatement on prior periods' financial statements in accordance with the Securities and Exchange Commission Staff Accounting Bulletin No. 99, Materiality , codified in Accounting Standards Codification (ASC) 250, Presentation of Financial Statements . We concluded that the misstatement was not material to any prior interim period and therefore, amendments of previously filed reports are not required. Periods presented herein will be revised, as applicable, in future Quarterly Reports on Form 10Q. The revisions had no impact on total assets, total liabilities, shareholders' equity, net income or net cash provided by operating activities. The revised total of cash, cash equivalents, restricted cash and restricted cash equivalents as of the end of each interim period in 2018 and 2017 is as follows: (in thousands) Cash, cash equivalents, restricted cash and restricted cash equivalents (unaudited) September 30, 2018 $ 126,114 June 30, 2018 145,303 March 31, 2018 146,479 September 30, 2017 115,172 June 30, 2017 105,479 March 31, 2017 160,000

Significant accounting policies (Policies)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Nature of operations	Nature of operations – We provide a selection of customer life cycle management solutions that help our customers acquire and engage their customers across multiple channels. We offer a wide range of services and products to small businesses, including hosting and domain name services, logo and web design, search engine marketing and optimization, email marketing, payroll services, and business incorporation and organization services, in addition to our checks, forms and promotional product offerings. For financial institutions, we offer our check program solutions, as well as a selection of financial technology solutions, including data-driven marketing, including outsourced marketing campaign targeting and execution; treasury management solutions, including accounts receivable processing and remote deposit capture; and digital engagement solutions, including loyalty and rewards programs. We are also a leading printer of checks and accessories sold directly to consumers.
Consolidation	Consolidation – The consolidated financial statements include the accounts of Deluxe Corporation and its wholly-owned subsidiaries. All intercompany accounts, transactions and profits have been eliminated.
Comparability	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	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	Foreign currency translation –
Cash and cash equivalents	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 – 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
Inventories and supplies	Inventories and supplies – Inventories are stated at the lower of cost or net realizable value. Cost is calculated on the first-in, first-out basis. Supplies consist of items not used directly in the production of goods, such as maintenance and other supplies utilized in the production area.
Funds held for customers	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.
Long-term investments	Long-term investments – Long-term investments consist primarily of cash surrender values of company-owned life insurance policies. Certain of these policies fund amounts due under our deferred compensation plan and our inactive supplemental executive retirement plan. Further information regarding these plans can be found in Notes 13 and 14.
Property, plant and equipment	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.
Assets held for sale	Assets held for sale –
Intangibles	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.
Impairment of long-lived assets and amortizable intangibles	Impairment of long-lived assets and amortizable intangibles – We evaluate the recoverability of property, plant, equipment and amortizable intangibles not held for sale whenever events or changes in circumstances indicate that an asset group's 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	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
Advertising costs	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	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
Restructuring and integration expense	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	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	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.
Derivative financial instruments	Derivative financial instruments – Information regarding our derivative financial instruments is included in Note 7. We did not have any derivative instruments outstanding as of December 31, 2018 or December 31, 2017, as we settled all of our interest rate swaps during 2016. We do not use derivative financial instruments for speculative or trading purposes. Our policy is that all derivative transactions must be linked to an existing balance sheet item or firm commitment, and the notional amount cannot exceed the value of the exposure being hedged.
Revenue recognition	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	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: • The fair value of stock options is measured on the grant date using the Black-Scholes option pricing model. The related compensation expense is recognized on the straight-line basis, net of estimated forfeitures, over the options' vesting periods. • The fair value of restricted stock and a portion of our restricted stock unit awards is measured on the grant date based on the market value of our common stock. The related compensation expense, net of estimated forfeitures, is recognized over the applicable service period. • Certain of our restricted stock unit awards may be settled in cash if an employee voluntarily chooses to leave the company. These awards are included in accrued liabilities and other non-current liabilities in the consolidated balance sheets and are re-measured at fair value as of each balance sheet date. • Compensation expense resulting from the 15% discount provided under our employee stock purchase plan is recognized over the purchase period of 6 months. • The performance share awards specify certain performance and market-based conditions that must be achieved in order for the awards to vest. For the portion of the awards based on a performance condition, the performance target is not considered in determining the fair value of the awards and thus, fair value is measured on the grant date based on the market value of our common stock. The related compensation expense for this type of award is recognized, net of estimated forfeitures, over the related service period. The amount of compensation expense is dependent on our periodic assessment of the probability of the targets being achieved and our estimate, which may vary over time, of the number of shares that ultimately will be issued. For the portion of the awards based on a market condition, fair value is calculated on the grant date using the Monte Carlo simulation model. All compensation cost for these awards is recognized, net of estimated forfeitures, over the related service period, even if the market condition is never satisfied.
Earnings per share	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.
Comprehensive income	Comprehensive income – Comprehensive income includes charges and credits to shareholders' equity that are not the result of transactions with shareholders. Our total comprehensive income consists of net income, changes in the funded status and amortization of amounts related to our postretirement benefit plans, unrealized gains and losses on available-for-sale debt securities, and foreign currency translation adjustments. The items of comprehensive income, with the exception of net income, are included in accumulated other comprehensive loss in the consolidated balance sheets and statements of shareholders' equity, net of their related tax impacts. We release stranded income tax effects from accumulated other comprehensive loss when the circumstances upon which they are premised cease to exist.
