Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Unaudited interim consolidated financial statements The accompanying interim consolidated financial statements have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission ("SEC") for interim financial reporting. These consolidated statements are unaudited and, in the opinion of management, include all adjustments (consisting of normal recurring adjustments and accruals) necessary to state fairly the consolidated balance sheets, consolidated statements of comprehensive income, consolidated statements of cash flows and consolidated statements of stockholders’ equity, for the periods presented in accordance with accounting principles generally accepted in the United States ("GAAP"). The consolidated balance sheet at December 31, 2015 , has been derived from the audited consolidated financial statements at that date. Operating results and cash flows for the nine months ended September 30, 2016 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2016 , or any other future period. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted in accordance with the rules and regulations for interim reporting of the SEC. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2015 , and other forms filed with the SEC from time to time. Reclassifications In order to provide comparability between periods presented, "interest income", "loss on sale of business", "loss on debt extinguishment and termination of derivative instruments" and "other income (expense), net" have been combined within "other expense, net" in the previously reported consolidated statements of comprehensive income to conform to presentation of the current period. See Note 7 to these consolidated financial statements for additional details. Basis of consolidation The consolidated financial statements include the accounts of Blackbaud, Inc. and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Use of estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. On an ongoing basis, we reconsider and evaluate our estimates and assumptions, including those that impact revenue recognition, long-lived and intangible assets including goodwill, stock-based compensation, the provision for income taxes, deferred taxes, capitalization of software development costs and related amortization, our allowances for sales returns and doubtful accounts, deferred sales commissions and professional services costs, valuation of derivative instruments, accounting for business combinations and loss contingencies. Changes in the facts or circumstances underlying these estimates could result in material changes and actual results could materially differ from these estimates. Revenue recognition Our revenue is primarily generated from the following sources: (i) charging for the use of our software solutions in cloud-based and hosted environments; (ii) providing software maintenance and support services; (iii) providing professional services including implementation, training, consulting, analytic, hosting and other services; (iv) providing transaction and payment processing services; and (v) selling perpetual licenses of our software solutions. We recognize revenue when all of the following conditions are met: • Persuasive evidence of an arrangement exists; • The solutions or services have been delivered; • The fee is fixed or determinable; and • Collection of the resulting receivable is probable. Determining whether and when these criteria have been met can require significant judgment and estimates. We deem acceptance of a contract to be evidence of an arrangement. Delivery of our services occurs when the services have been performed. Delivery of our solutions occurs when the solution is shipped or transmitted, and title and risk of loss have transferred to the customers. Our typical arrangements do not include customer acceptance provisions; however, if acceptance provisions are provided, delivery is deemed to occur upon acceptance. We consider the fee to be fixed or determinable unless the fee is subject to refund or adjustment or is not payable within our standard payment terms. Payment terms greater than 90 days are considered to be beyond our customary payment terms. Collection is deemed probable if we expect that the customer will be able to pay amounts under the arrangement as they become due. If we determine that collection is not probable, we defer revenue recognition until collection. Revenue is recognized net of actual and estimated sales returns and allowances. We follow guidance provided in ASC 605-45, Principal Agent Considerations , which states that determining whether a company should recognize revenue based on the gross amount billed to a customer or the net amount retained is a matter of judgment that depends on the facts and circumstances of the arrangement and that certain factors should be considered in the evaluation. Subscriptions We provide software solutions to customers which are available for use in cloud-based subscription arrangements without licensing perpetual rights to the software (“cloud-based solutions”). Revenue from cloud-based solutions is recognized ratably beginning on the activation date over the term of the agreement, which generally ranges from one to three years. Any revenue related to upfront activation or set-up fees is deferred and recognized ratably over the estimated period that the customer benefits from the related cloud-based solution. Direct and incremental costs related to upfront activation or set-up activities for cloud-based solutions are capitalized until the cloud-based solution is deployed and in use, and then expensed ratably over the estimated period that the customer benefits from the related cloud-based solution. We provide hosting services to customers who have purchased perpetual rights to certain of our software solutions (“hosting services”). Revenue from hosting services, online training programs as well as subscription-based analytic services such as data enrichment and data management services, is recognized ratably beginning on the activation date over the term of the agreement, which generally ranges from one to three years. Any related set-up fees are recognized ratably over the estimated period that the customer benefits from the related hosting service. The estimated period of benefit is evaluated on an annual basis using historical customer retention information by solution or service. For arrangements that have multiple elements and do not include software licenses, we allocate arrangement consideration at the inception of the arrangement to those elements that qualify as separate units of accounting. The arrangement consideration is allocated to the separate units of accounting based on relative selling price method in accordance with the selling price hierarchy, which includes: (i) vendor specific objective evidence (“VSOE”) of fair value if available; (ii) third-party evidence (“TPE”) if VSOE is not available; and (iii) best estimate of selling price (“BESP”) if neither VSOE nor TPE is available. In general, we use VSOE to allocate the selling price to subscription and service deliverables. We offer certain payment processing services with the assistance of third-party vendors. In general, when we are the principal in a transaction based on the predominant weighting of factors identified in ASC 605-45, we record the revenue and related costs on a gross basis. Otherwise, we net the cost of revenue associated with the service against the gross amount billed to the customer and record the net amount as revenue. Revenue from transaction processing services is recognized when the service is provided and the amounts are determinable. Revenue directly associated with processing donations for customers are included in subscriptions revenue. Maintenance We recognize revenue from maintenance services ratably over the term of the arrangement, generally one year at contract inception with annual renewals thereafter. Maintenance contracts are at rates that vary according to the level of the maintenance program associated with the software solution and are generally renewable annually. Maintenance contracts may also include the right to unspecified solution upgrades on an if-and-when available basis. Certain incremental support services are sold in prepaid units of time and recognized as revenue upon their usage. Services We generally bill consulting, installation and implementation services based on hourly rates plus reimbursable travel-related expenses. Revenue is recognized for these services over the period the services are delivered. We recognize analytic services revenue from donor prospect research engagements, the sale of lists of potential donors, benchmarking studies and data modeling service engagements upon delivery. In arrangements where we provide customers the right to updated information during the contract period, revenue is recognized ratably over the contract period. We sell fixed-rate programs, which permit customers to attend unlimited training over a specified contract period, typically one year, subject to certain restrictions, and revenue in those cases is recognized ratably over the contract period. Additionally, we sell training at a fixed rate for each specific class at a per attendee price or at a packaged price for several attendees, and recognize the related revenue upon the customer attending and completing training. License fees We sell perpetual software licenses with maintenance, varying levels of professional services and, in certain instances, with hosting services. We allocate revenue to each of the elements in these arrangements using the residual method under which we first allocate revenue to the undelivered elements, typically the non-software license components, based on VSOE of fair value of the various elements. We determine VSOE of fair value of the various elements using different methods. VSOE of fair value for maintenance services associated with software licenses is based upon renewal rates stated in the arrangements with customers, which demonstrate a consistent relationship of maintenance pricing as a percentage of the contractual license fee. VSOE of fair value of professional services and other solutions and services is based on the average selling price of these same solutions and services to other customers when sold on a stand-alone basis. Any remaining revenue is allocated to the delivered elements, which is normally the software license in the arrangement. In general, revenue is recognized for software licenses upon delivery to our customers. When a software license is sold with software customization services, generally the services are to provide the customer assistance in creating special reports and other enhancements that will improve operational efficiency and/or help to support business process improvements. These services are generally not essential to the functionality of the software and the related revenues are recognized either as the services are delivered or upon completion. However, when software customization services are considered essential to the functionality of the software, we recognize revenue for both the software license and the services using the percentage-of-completion method. Deferred revenue To the extent that our customers are billed for the above described solutions and services in advance of delivery, we record such amounts in deferred revenue. Generally, our subscription and maintenance customers are billed one year in advance. Fair value measurements We measure certain financial assets and liabilities at fair value on a recurring basis, including derivative instruments. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. An active market is defined as a market in which transactions for the asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis. We use a three-tier fair value hierarchy to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows: • Level 1 - Quoted prices for identical assets or liabilities in active markets; • Level 2 - Quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and • Level 3 - Valuations derived from valuation techniques in which one or more significant inputs are unobservable. Our financial assets and liabilities are classified in their entirety within the hierarchy based on the lowest level of input that is significant to fair value measurement. Changes to a financial asset's or liability's level within the fair value hierarchy are determined as of the end of a reporting period. All methods of assessing fair value result in a general approximation of value, and such value may never actually be realized. Earnings per share We compute basic earnings per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income available to common stockholders by the weighted average number of common shares and dilutive potential common shares outstanding during the period. Diluted earnings per share reflect the assumed exercise, settlement and vesting of all dilutive securities using the “treasury stock method” except when the effect is anti-dilutive. Potentially dilutive securities consist of shares issuable upon the exercise of stock options, settlement of stock appreciation rights and vesting of restricted stock awards and units. Recently adopted accounting pronouncements In September 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments (ASU 2015-16) . ASU 2015-16 requires for acquirers in business combinations to recognize adjustments to provisional amounts identified during measurement periods in the reporting periods in which adjusted amounts are determined. The update requires that acquirers record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization or other income effects, if any, resulting from changes in provisional amounts, calculated as if the accounting had been completed at acquisition date. The update also requires separate income statement presentation or note disclosure of amounts recorded in current period earnings by line item that would have been recorded in previous reporting periods if the provisional amount adjustments had been recognized at the acquisition date (requirements to retrospectively account for those adjustments have been eliminated). The guidance is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Amendments in this update should be applied prospectively to adjustments to provisional amounts that occur after its effective date, with earlier application permitted for financial statements that have not been issued. We adopted ASU 2015-16 on January 1, 2016. See Note 3 to these consolidated financial statements for details of any immaterial measurement period adjustments. In April 2015, the FASB issued ASU No. 2015-05, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer's Accounting for Fees Paid in a Cloud Computing Arrangement (ASU 2015-05) . The amendments in this update provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the update specifies that the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. The update further specifies that the customer should account for a cloud computing arrangement as a service contract if the arrangement does not include a software license. An entity can elect to adopt the amendments either (1) prospectively to all arrangements entered into or materially modified after the effective date or (2) retrospectively. We adopted ASU 2015-05 on January 1, 2016 on a prospective basis and it did not have a material impact on our consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest - Simplifying the Presentation of Debt Issuance Costs (ASU 2015-03) . ASU 2015-03 sets forth a requirement that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs is not affected by the amendments in this update. An entity should apply the new guidance on a retrospective basis, wherein the balance sheet of each individual period presented is adjusted to reflect the period-specific effects of applying the new guidance. We adopted ASU 2015-03 on January 1, 2016 and retrospectively restated "other assets" and "debt, net of current portion", which had the effect of reducing each of those respective line items in our December 31, 2015 consolidated balance sheet by approximately $0.5 million . In March 2016, the FASB issued ASU 2016-09, Compensation — Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting (ASU 2016-09) . The new guidance requires excess tax benefits and tax deficiencies to be recorded in the income statement when the awards vest or are settled and provides an accounting policy election to account for forfeitures as they occur. In addition, cash flows related to excess tax benefits will no longer be separately classified as a financing activity apart from other income tax cash flows within operating activities. The standard also allows entities to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting and clarifies that all cash payments made on an employee’s behalf for withheld shares should be presented as a financing activity on the statements of cash flows. The new standard is effective for fiscal years beginning after December 15, 2016, with early adoption permitted. We early adopted ASU 2016-09 during the three months ended September 30, 2016, which requires us to reflect any adjustments as of January 1, 2016, the beginning of the annual period that includes the interim period of adoption. Upon adoption, we elected to account for forfeitures as they occur using a modified retrospective transition method, which resulted in a cumulative-effect adjustment of $0.9 million to reduce our January 1, 2016 opening retained earnings balance. The following table summarizes the impact to our consolidated balance sheet, including the net amount charged to retained earnings as of January 1, 2016: (dollars in thousands) As of January 1, 2016 Balance sheet location Amount Decrease in deferred tax liabilities related to the cumulative effect adjustment from our election to recognize forfeitures as they occur rather than applying an estimated forfeiture rate Deferred tax liability $ (606 ) Increase in additional paid-in capital resulting from our election to recognize forfeitures as they occur Additional paid-in capital $ 1,540 Net charge to retained earnings for cumulative effect adjustment from adoption of ASU 2016-09 Retained earnings $ (934 ) We elected to retrospectively apply the changes in presentation to the statements of cash flows and no longer classify excess tax benefits as a financing activity, which increased both net cash provided by operating activities and net cash used in financing activities by $1.5 million for the nine months ended September 30, 2015. The presentation requirements for cash flows related to employee taxes paid for withheld shares increased both net cash provided by operating activities and net cash used in financing activities for the nine months ended September 30, 2015 by $2.7 million , as such cash flows were historically presented within operating cash flows. Adoption of the new standard resulted in the recognition of additional stock-based compensation expense of approximately $0.6 million and $1.0 million for the three and nine months ended September 30, 2016, respectively, as well as the recognition of excess tax benefits in our provision for income taxes rather than paid-in capital of $1.6 million and $4.3 million for the three and nine months ended September 30, 2016, respectively. The adoption of ASU 2016-09 impacted our previously reported quarterly results for fiscal year 2016 as follows: Consolidated balance sheets: (dollars in thousands) As of March 31, 2016 As of June 30, 2016 As Reported As Adjusted As Reported As Adjusted Additional paid-in capital $ 285,376 $ 285,606 $ 294,810 $ 294,019 Retained earnings $ 134,192 $ 134,500 $ 136,338 $ 137,893 Consolidated statements of comprehensive income: (dollars in thousands, except per share amounts) Three months ended March 31, 2016 Three months ended June 30, 2016 As Reported As Adjusted As Reported As Adjusted Income tax provision $ 2,664 $ 1,595 $ 3,598 $ 1,778 Net income $ 4,995 $ 6,237 $ 7,813 $ 9,060 Basic earnings per share $ 0.11 $ 0.14 $ 0.17 $ 0.20 Diluted earnings per share $ 0.11 $ 0.13 $ 0.17 $ 0.19 Diluted weighted average shares outstanding 46,757,458 47,064,164 46,927,626 47,263,844 Consolidated statements of cash flows: (dollars in thousands) Three months ended March 31, 2016 Six months ended June 30, 2016 As Reported As Adjusted As Reported As Adjusted Net cash provided by operating activities $ 104 $ 6,757 $ 37,987 $ 48,753 Net cash provided by (used in) financing activities $ 9,546 $ 2,893 $ (13,852 ) $ (24,618 ) Recently issued accounting pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (ASU 2016-02) . ASU 2016-02 will require lessees to record most leases on their balance sheets but recognize expenses in the income statement in a manner similar to current guidance. The updated guidance also eliminates certain real estate-specific provisions and changes the guidance on sale-leaseback transactions, initial direct costs and lease executory costs for all entities. For lessors, the standard modifies the classification criteria and the accounting for sales-type and direct financing leases. All entities will classify leases to determine how to recognize lease-related revenue and expense. Classification will continue to affect amounts that lessors record on the balance sheet. ASU 2016-02 is effective for annual periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted. Upon adoption, entities will be required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. We expect ASU 2016-02 will impact our consolidated financial statements and are currently evaluating the extent of the impact that implementation of this standard will have on adoption. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU 2014-09) . ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will replace most existing revenue recognition guidance in GAAP when it becomes effective. ASU 2014-09 was originally effective for fiscal years and interim periods within those years beginning after December 15, 2016. An entity should apply ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying the ASU recognized as an adjustment to the opening balance of retained earnings at the date of initial application. In July 2015, the FASB decided to delay the effective date of the new standard for one year. The new standard now requires application no later than annual reporting periods beginning after December 15, 2017, including interim reporting periods therein; however, public entities are permitted to elect to early adopt the new standard as of the original effective date. In March 2016, the FASB finalized amendments to the guidance in the new standard to clarify whether an entity is a principal or an agent in a revenue transaction. In April 2016, the FASB finalized additional amendments to the guidance in the new standard to clarify the accounting for licenses of intellectual property and identifying performance obligations. We expect the adoption of ASU 2014-09 will impact our consolidated financial statements. We are currently evaluating implementation methods and the extent of the impact that implementation of this standard and the recently issued clarifying amendments will have upon adoption.

Business Combinations [Abstract]
Business Combinations	3. Business Combinations 2016 Acquisition Attentive.ly On July 11, 2016 , we acquired all of the outstanding equity, including all voting equity interests of Good+Geek, Inc., a Delaware corporation doing business as "Attentive.ly." Attentive.ly provides social media capabilities allowing organizations to conduct social listening, identify key influencers and drive engagement through its cloud solution. The acquisition accelerates our ability to deliver these capabilities to our customers. We acquired Attentive.ly for $3.9 million in cash, net of closing adjustments. Of that purchase price, $1.3 million was allocated to the acquired finite-lived intangible technology asset, which will be amortized over its estimated useful life of five years. The estimated amount of goodwill arising from the acquisition was assigned to the General Markets Business Unit ("GMBU") reporting segment and the Enterprise Customer Business Unit ("ECBU") reporting segment was $1.9 million and $0.4 million , respectively. None of the goodwill is deductible for tax purposes. The carrying amounts of all other assets acquired and liabilities assumed are insignificant and approximate their estimated fair values. The assets and liabilities recorded for the acquisition of Attentive.ly were based on preliminary valuations and the estimates and assumptions are subject to change as we obtain additional information during the measurement period, which may be up to one year from the acquisition date. We included the operating results of Attentive.ly, which are insignificant, in our consolidated financial statements from the date of acquisition. We do not expect this business combination to have a material effect on our consolidated financial position, results of operations or cash flows. We determined that the Attentive.ly acquisition was not a material business combination; therefore, pro forma disclosures have not been presented. 2015 Acquisition Smart Tuition On October 2, 2015 , we completed our acquisition of all of the outstanding equity, including all voting equity interests, of Smart, LLC (“Smart Tuition”). Smart Tuition is a leading provider of payment software and services for private schools and parents. The acquisition of Smart Tuition further expanded our offerings in the K-12 technology sector. We acquired Smart Tuition for $187.3 million in cash, net of closing adjustments including an adjustment of approximately $0.5 million during the three months ended March 31, 2016. We received the proceeds from these closing adjustments during the three months ended September 30, 2016 . On October 2, 2015 , we drew down a $186.0 million revolving credit loan under our 2014 Credit Facility (as defined in Note 8 below) to finance the acquisition of Smart Tuition. As a result of the acquisition, Smart Tuition has become a wholly-owned subsidiary of ours. We included the operating results of Smart Tuition in our consolidated financial statements within our GMBU reporting segment from the date of acquisition. For the three months ended September 30, 2016 , Smart Tuition's total revenue and operating income included in our consolidated financial statements was $10.3 million and $1.0 million , respectively. For the nine months ended September 30, 2016 , Smart Tuition's total revenue and operating income included in our consolidated financial statements was $27.7 million and $2.8 million , respectively. The following table summarizes the allocation of the purchase price based on the estimated fair value of the assets acquired and the liabilities assumed: (dollars in thousands) Purchase Price Allocation Net working capital, excluding deferred revenue $ 202 Property and equipment 2,457 Deferred revenue (6,500 ) Deferred tax asset 2,637 Intangible assets 97,800 Goodwill 90,376 Total purchase price (1) $ 186,972 (1) The purchase price differs from the net cash outlay of $187.3 million due to certain insignificant acquisition-related expenses included therein. The estimated fair value of accounts receivable acquired approximates the contractual value of $2.8 million . The estimated goodwill recognized is attributable primarily to the opportunities for expected synergies from combining operations and the assembled workforce of Smart Tuition, all of which was assigned to our GMBU reporting segment. Approximately $86.3 million of the goodwill arising from the acquisition is deductible for income tax purposes. We finalized the purchase price allocation for Smart Tuition, including the valuation of assets acquired and liabilities assumed, during the third quarter of 2016. All measurement period adjustments recorded were not significant. The Smart Tuition acquisition resulted in the identification of the following identifiable intangible assets: Intangible assets acquired Weighted average amortization period (in thousands) (in years) Customer relationships $ 72,300 17 Marketing assets 1,200 3 Acquired technology 22,100 7 Non-compete agreements 2,200 5 Total intangible assets $ 97,800 14 The estimated fair values of the finite-lived intangible assets were based on variations of the income approach, which estimates fair value based on the present value of cash flows that the assets are expected to generate which included the relief-from-royalty method, incremental cash flow method including the with and without method and excess earnings method, depending on the intangible asset being valued. The method of amortization of identifiable finite-lived intangible assets is based on the expected pattern in which the estimated economic benefits of the respective assets are consumed or otherwise used up. Customer relationships and acquired technology are being amortized on an accelerated basis while marketing assets and non-compete agreements are being amortized on a straight-line basis. The following unaudited pro forma condensed combined consolidated results of operations assume that the acquisition of Smart Tuition occurred on January 1, 2014. This unaudited pro forma financial information does not reflect any adjustments for anticipated synergies resulting from the acquisition and should not be relied upon as being indicative of the historical results that would have been attained had the transaction been consummated as of January 1, 2014, or of the results that may occur in the future. The unaudited pro forma information reflects adjustments for amortization of intangibles related to the fair value adjustments of the assets acquired, write-down of acquired deferred revenue to fair value, additional interest expense related to the financing of the transaction and the related tax effects of the adjustments.

Fair Value Measurements	5. Fair Value Measurements Recurring fair value measurements Financial assets and liabilities measured at fair value on a recurring basis consisted of the following, as of: Fair value measurement using (dollars in thousands) Level 1 Level 2 Level 3 Total Fair value as of September 30, 2016 Financial liabilities: Derivative instruments (1) $ — $ 654 $ — $ 654 Total financial liabilities $ — $ 654 $ — $ 654 Fair value as of December 31, 2015 Financial assets: Derivative instruments (1) $ — $ 406 $ — $ 406 Total financial assets $ — $ 406 $ — $ 406 Fair value as of December 31, 2015 Financial liabilities: Derivative instruments (1) $ — $ 438 $ — $ 438 Total financial liabilities $ — $ 438 $ — $ 438 (1) The fair value of our interest rate swaps was based on model-driven valuations using LIBOR rates, which are observable at commonly quoted intervals. Accordingly, our interest rate swaps are classified within Level 2 of the fair value hierarchy. We believe the carrying amounts of our cash and cash equivalents, restricted cash due to customers, accounts receivable, trade accounts payable, accrued expenses and other current liabilities and due to customers approximate their fair values at September 30, 2016 and December 31, 2015 , due to the immediate or short-term maturity of these instruments. We believe the carrying amount of our debt approximates its fair value at September 30, 2016 and December 31, 2015 , as the debt bears interest rates that approximate market value. As LIBOR rates are observable at commonly quoted intervals, our debt is classified within Level 2 of the fair value hierarchy. We did not transfer any assets or liabilities among the levels within the fair value hierarchy during the nine months ended September 30, 2016 . Additionally, we did not hold any Level 3 assets or liabilities during the nine months ended September 30, 2016 . Non-recurring fair value measurements Assets and liabilities that are measured at fair value on a non-recurring basis include intangible assets and goodwill, which are recognized at fair value during the period in which an acquisition is completed, from updated estimates and assumptions during the measurement period, or when they are considered to be impaired. These non-recurring fair value measurements, primarily for intangible assets acquired, were based on Level 3 unobservable inputs. In the event of an impairment, we determine the fair value of the goodwill and intangible assets using a discounted cash flow approach, which contains significant unobservable inputs and, therefore, is considered a Level 3 fair value measurement. The unobservable inputs in the analysis generally include future cash flow projections and a discount rate. There were no non-recurring fair value adjustments to intangible assets and goodwill during the nine months ended September 30, 2016 , except for certain insignificant business combination accounting adjustments to the initial fair value estimates of the Smart Tuition assets acquired and liabilities assumed at the acquisition date from updated information obtained during the measurement period. See Note 3 to these consolidated financial statements for additional details. The measurement period of a business combination may be up to one year from the acquisition date. We record any measurement period adjustments to the fair value of assets acquired and liabilities assumed, with the corresponding offset to goodwill.

The 2014 Credit Facility includes the following facilities: (i) a dollar and a designated currency revolving credit facility with sublimits for letters of credit and swingline loans (the “2014 Revolving Facility”) and (ii) a term loan facility (the “2014 Term Loan”). In connection with our entry into the 2014 Credit Facility, we paid $2.5 million in financing costs, of which $1.1 million were capitalized and, together with a portion of the unamortized deferred financing costs from prior facilities, are being amortized into interest expense over the term of the new facility using the effective interest method. As of September 30, 2016 and December 31, 2015 , deferred financing costs totaling $0.7 million and $0.9 million , respectively, were included in other assets on the consolidated balance sheet. The 2014 Credit Facility is secured by the stock and limited liability company interests of certain of our subsidiaries and is guaranteed by our material domestic subsidiaries. Amounts borrowed under the dollar tranche revolving credit loans and term loan under the 2014 Credit Facility bear interest at a rate per annum equal to, at our option, (a) a base rate equal to the highest of (i) the prime rate, (ii) federal funds rate plus 0.50% and (iii) one month LIBOR plus 1.00% (the “Base Rate”), in addition to a margin of 0.00% to 0.50% , or (b) LIBOR rate plus a margin of 1.00% to 1.50% . We also pay a quarterly commitment fee on the unused portion of the 2014 Revolving Facility from 0.15% to 0.225% per annum, depending on our net leverage ratio. At September 30, 2016 , the commitment fee was 0.225% . The 2014 Term Loan requires periodic principal payments. The balance of the 2014 Term Loan and any amounts drawn on the 2014 Revolving Facility are due upon maturity of the 2014 Credit Facility in February 2019. We evaluate the classification of our debt as current or non-current based on the required annual maturities of the 2014 Credit Facility. The 2014 Credit Facility includes financial covenants related to the net leverage ratio and interest coverage ratio, as well as restrictions on our ability to declare and pay dividends and our ability to repurchase shares of our common stock. At September 30, 2016 , we were in compliance with our debt covenants under the 2014 Credit Facility. Financing for MicroEdge acquisition The 2014 Credit Facility includes an option to request increases in the revolving commitments and/or request additional term loans in an aggregate principal amount of up to $200.0 million . On October 1, 2014, we exercised this option, and certain lenders agreed, to increase the revolving credit commitments by $100.0 million (the "October 2014 Additional Revolving Credit Commitments") such that for the period commencing October 1, 2014, the aggregate revolving credit commitments available were $250.0 million . The October 2014 Additional Revolving Credit Commitments have the same terms as the existing revolving credit commitments. On October 1, 2014, we drew down a $140.0 million revolving credit loan under the 2014 Credit Facility to finance the acquisition of MicroEdge. Financing for Smart Tuition acquisition On July 17, 2015, we again exercised this option and certain lenders agreed to increase the revolving credit commitments by an additional $100.0 million (the "July 2015 Additional Revolving Credit Commitments") such that commencing July 17, 2015, the aggregate revolving credit commitments available were $350.0 million . The July 2015 Additional Revolving Credit Commitments have the same terms as the existing revolving credit commitments. On October 2, 2015 , we drew down a $186.0 million revolving credit loan under the 2014 Credit Facility to finance the acquisition of Smart Tuition. As of September 30, 2016 , the required annual maturities related to the 2014 Credit Facility were as follows: Years ending December 31, (dollars in thousands) Annual maturities 2016 - remaining $ 1,094 2017 4,375 2018 4,375 2019 366,819 2020 — Thereafter — Total required maturities $ 376,663

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives Instruments	9. Derivative Instruments We use derivative instruments to manage our variable interest rate risk. In March 2014 , we entered into an interest rate swap agreement (the "March 2014 Swap Agreement"), which effectively converts portions of our variable rate debt under the 2014 Credit Facility to a fixed rate for the term of the swap agreement. The initial notional value of the March 2014 Swap Agreement was $125.0 million with an effective date beginning in March 2014 . In March 2017 , the notional value of the March 2014 Swap Agreement will decrease to $75.0 million for the remaining term through February 2018 . We designated the March 2014 Swap Agreement as a cash flow hedge at the inception of the contract. In October 2015 , we entered into an additional interest rate swap agreement (the "October 2015 Swap Agreement"), which effectively converts portions of our variable rate debt under the 2014 Credit Facility to a fixed rate for the term of the October 2015 Swap Agreement. The notional value of the October 2015 Swap Agreement was $75.0 million with an effective date beginning in October 2015 and maturing in February 2018 . We designated the October 2015 Swap Agreement as a cash flow hedge at the inception of the contract. The fair values of our derivative instruments were as follows as of: (dollars in thousands) Balance sheet location September 30, December 31, Derivative instruments designated as hedging instruments: Interest rate swap, long-term portion Other assets $ — $ 406 Total derivative instruments designated as hedging instruments $ — $ 406 September 30, December 31, Derivative instruments designated as hedging instruments: Interest rate swaps, current portion Accrued expenses and other current liabilities $ — $ 2 Interest rate swaps, long-term portion Other liabilities 654 436 Total derivative instruments designated as hedging instruments $ 654 $ 438 The effects of derivative instruments in cash flow hedging relationships were as follows: Gain (loss) recognized in accumulated other comprehensive loss as of Location of gain (loss) reclassified from accumulated other comprehensive loss into income Gain (loss) reclassified from accumulated other comprehensive loss into income (dollars in thousands) September 30, Three months ended Nine months ended Interest rate swaps $ (654 ) Interest expense $ (265 ) $ (875 ) September 30, Three months ended Nine months ended Interest rate swaps $ (1,312 ) Interest expense $ (373 ) $ (1,122 ) Our policy requires that derivatives used for hedging purposes be designated and effective as a hedge of the identified risk exposure at the inception of the contract. Accumulated other comprehensive income (loss) includes unrealized gains or losses from the change in fair value measurement of our derivative instruments each reporting period and the related income tax expense or benefit. Changes in the fair value measurements of the derivative instruments and the related income tax expense or benefit are reflected as adjustments to accumulated other comprehensive income (loss) until the actual hedged expense is incurred or until the hedge is terminated at which point the unrealized gain (loss) is reclassified from accumulated other comprehensive income (loss) to current earnings. The estimated accumulated other comprehensive loss as of September 30, 2016 that is expected to be reclassified into earnings within the next twelve months is $0.6 million . There were no ineffective portions of our interest rate swap derivatives during the nine months ended September 30, 2016 and 2015 . See Note 13 to these consolidated financial statements for a summary of the changes in accumulated other comprehensive income (loss) by component.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	10. Commitments and Contingencies Historical Leases We lease our headquarters facility under a 15 -year lease agreement which was entered into in October 2008 , and has two five -year renewal options. The current annual base rent of the lease is $5.1 million , payable in equal monthly installments. The base rent escalates annually at a rate equal to the change in the consumer price index, as defined in the agreement, but not to exceed 5.5% in any year. We have a lease for office space in Austin, Texas which terminates on September 30, 2023, and has two five -year renewal options. The current annual base rent of the lease is $2.7 million . The base rent escalates annually between 2% and 4% based on the terms of the agreement. The rent expense is recorded on a straight-line basis over the length of the lease term. At September 30, 2016 , we had a standby letter of credit of $2.0 million for a security deposit for this lease. We have provisions in our leases that entitle us to aggregate remaining leasehold improvement allowances of $4.9 million . These amounts are being recorded as a reduction to rent expense ratably over the terms of the leases. The reductions in rent expense related to these lease provisions during the three months ended September 30, 2016 and 2015 were insignificant. The reductions in rent expense related to these lease provisions during the nine months ended September 30, 2016 and 2015 , were $0.6 million and $0.6 million , respectively. The leasehold improvement allowances have been included in the table of operating lease commitments below as a reduction in our lease commitments ratably over the then remaining terms of the leases. The timing of the reimbursements for the actual leasehold improvements may vary from the amounts reflected in the table below. We have also received, and expect to receive through 2016, quarterly South Carolina state incentive payments as a result of locating our headquarters facility in Berkeley County, South Carolina. These amounts are recorded as a reduction of rent expense upon receipt and were $0.6 million and $0.6 million for the three months ended September 30, 2016 and 2015 , respectively, and $2.2 million and $1.8 million for the nine months ended September 30, 2016 and 2015 , respectively. Total rent expense was $3.1 million and $2.5 million for the three months ended September 30, 2016 and 2015 , respectively, and $8.6 million and $7.4 million for the nine months ended September 30, 2016 and 2015 , respectively. Lease for New Headquarters Facility In May 2016, we entered into a lease agreement for a new headquarters facility to be built in Charleston, South Carolina (the "New Headquarters Facility"). The landlord is responsible for the design, development and construction of the New Headquarters Facility. Construction of the New Headquarters Facility will proceed in two phases. Phase One will include a building with approximately 172,000 rentable square feet, which is expected to be completed in the first quarter of 2018. The lease agreement also grants us a Phase Two option to request that the landlord construct and lease to us a second office building and related improvements. Total rent payments and leasehold improvement allowances for Phase One are estimated to be approximately $102.0 million and $12.9 million , respectively, over the life of the lease agreement, plus additional amounts for Phase Two, if applicable. The lease agreement is for a period of twenty years beginning on the date of substantial completion of construction by the landlord, which is estimated to be in the first quarter of 2018, and ending in the first quarter of 2038. The lease agreement provides for four renewal periods of five years each at a base rent equal to the then prevailing market rate for comparable buildings. We expect to receive quarterly South Carolina state incentive payments as a result of locating our headquarters facility in Berkeley County, South Carolina. As of September 30, 2016 , the future minimum lease commitments related to lease agreements, net of related lease incentives, were as follows: Years ending December 31, (dollars in thousands) Operating leases (1) 2016 – remaining $ 3,427 2017 12,531 2018 15,663 2019 15,954 2020 15,309 Thereafter 110,088 Total minimum lease payments $ 172,972 (1) Our future minimum lease commitments related to operating leases do not include payments related to Phase Two of our New Headquarters Facility, as that option had not been exercised as of September 30, 2016 . Other commitments As discussed in Note 8 to these consolidated financial statements, the term loans under the 2014 Credit Facility require periodic principal payments. The balance of the term loans and any amounts drawn on the revolving credit loans are due upon maturity of the 2014 Credit Facility in February 2019 . We utilize third-party technology in conjunction with our solutions and services, with contractual obligations varying in length from one to four years. In certain cases, such arrangements require a minimum annual purchase commitment. As of September 30, 2016 , the remaining aggregate minimum purchase commitment under these arrangements was approximately $35.7 million through 2020. Product and service indemnifications In the ordinary course of business, we provide certain indemnifications of varying scope to customers against claims of intellectual property infringement made by third parties arising from the use of our solutions or services. If we determine that it is probable that a loss has been incurred related to solution or service indemnifications, any such loss that could be reasonably estimated would be recognized. We have not identified any losses and, accordingly, we have not recorded a liability related to these indemnifications. Legal contingencies We are subject to legal proceedings and claims that arise in the ordinary course of business. We record an accrual for a contingency when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. As of September 30, 2016 , in our opinion, there was not at least a reasonable possibility that these actions arising in the ordinary course of business will have a material adverse effect upon our consolidated financial position, results of operations or cash flows and, therefore, no material loss contingencies were recorded.

Income Tax Disclosure [Abstract]
Income Taxes	11. Income Taxes Our income tax provision and effective income tax rates including the effects of period-specific events, were: Three months ended September 30, Nine months ended (dollars in thousands) 2016 2015 2016 2015 Income tax provision $ 1,950 $ 4,433 $ 5,323 $ 10,459 Effective income tax rate 17.9 % 35.9 % 18.0 % 35.2 % The decreases in our effective income tax rates during the three and nine months ended September 30, 2016 , when compared to the same periods in 2015 , were primarily due to discrete tax benefits from the early adoption of ASU 2016-09 relating to stock-based compensation. Under ASU 2016-09, excess tax benefits generated upon the settlement or exercise of stock awards are no longer recognized as additional paid-in capital but are instead recognized as a reduction to income tax expense. The remaining impacts to our effective income tax rates for these periods were the estimated benefit to our annual 2016 effective tax rate from federal and state research tax credits that were permanently enacted into law in December 2015 and a discrete tax benefit included in the 2016 periods from statute of limitations expiration, partially offset by the estimated impact to our annual 2016 effective tax rate from Section 162(m) nondeductible compensation. In addition to the events that impact our effective income tax rate during both the three and nine months ended September 30, 2016 , when compared to the same periods in 2015 , the decrease in our effective tax rate during the nine months ended September 30, 2016 was also partially offset by a discrete tax benefit included in the 2015 period from the settlement of an IRS audit. Our effective income tax rate may fluctuate quarterly as a result of factors, including transactions entered into, changes in the geographic distribution of our earnings or losses, our assessment of certain tax contingencies, valuation allowances, and changes in tax law in jurisdictions where we conduct business. We have deferred tax assets for federal, state, and international net operating loss carryforwards and state tax credits. The federal and state net operating loss carryforwards are subject to various Internal Revenue Code limitations and applicable state tax laws. A portion of the foreign and state net operating loss carryforwards and a portion of state tax credits have a valuation reserve due to the uncertainty of realizing such carryforwards and credits in the future. The total amount of unrecognized tax benefit that, if recognized, would favorably affect the effective income tax rate, was $2.2 million and $2.3 million at September 30, 2016 and December 31, 2015 , respectively. We recognize accrued interest and penalties, if any, related to unrecognized tax benefits as a component of income tax expense.

Stockholders' Equity	13. Stockholders' Equity Dividends Our Board of Directors has adopted a dividend policy, which provides for the distribution to stockholders of a portion of cash generated by us that is in excess of operational needs and capital expenditures. The 2014 Credit Facility limits the amount of dividends payable and certain state laws restrict the amount of dividends distributed. In February 2016 , our Board of Directors approved an annual dividend rate of $0.48 per share to be made in quarterly payments. Dividend payments are not guaranteed and our Board of Directors may decide, in its absolute discretion, at any time and for any reason, not to declare and pay further dividends. The following table provides information with respect to quarterly dividends of $0.12 per share paid on common stock during the nine months ended September 30, 2016 .

Segment Reporting [Abstract]
Segment Information	14. Segment Information As of September 30, 2016 , our reportable segments were the General Markets Business Unit ("GMBU"), the Enterprise Customer Business Unit ("ECBU"), and the International Business Unit ("IBU"). Following is a description of each reportable segment: • The GMBU is focused on marketing, sales, delivery and support to all emerging and mid-sized prospects and customers in North America; • The ECBU is focused on marketing, sales, delivery and support to all large and/or strategic prospects and customers in North America; and • The IBU is focused on marketing, sales, delivery and support to all prospects and customers outside of North America. Our chief operating decision maker is our chief executive officer ("CEO"). The CEO reviews financial information presented on an operating segment basis for the purposes of making certain operating decisions and assessing financial performance. The CEO uses internal financial reports that provide segment revenues and operating income, excluding stock-based compensation expense, amortization expense, depreciation expense, research and development expense and certain corporate sales, marketing, general and administrative expenses. Currently, the CEO believes that the exclusion of these costs allows for a better understanding of the operating performance of the operating units and management of other operating expenses and cash needs. The CEO does not review any segment balance sheet information. Summarized reportable segment financial results, were as follows: Three months ended September 30, Nine months ended (dollars in thousands) 2016 2015 2016 2015 Revenue by segment: GMBU $ 97,621 $ 78,244 $ 279,543 $ 224,311 ECBU 74,351 69,326 220,887 205,625 IBU 11,030 11,181 31,926 31,995 Other (1) 61 60 154 132 Total revenue $ 183,063 $ 158,811 $ 532,510 $ 462,063 Segment operating income (2) : GMBU $ 46,540 $ 40,718 $ 134,408 $ 114,719 ECBU 38,696 33,568 113,186 99,522 IBU 1,064 2,431 3,126 5,823 Other (1) (157 ) (219 ) (109 ) (276 ) 86,143 76,498 250,611 219,788 Less: Corporate unallocated costs (3) (53,236 ) (47,975 ) (156,013 ) (141,162 ) Stock-based compensation costs (8,818 ) (6,486 ) (25,005 ) (17,899 ) Amortization expense (10,549 ) (8,069 ) (31,817 ) (24,286 ) Interest expense (2,641 ) (1,816 ) (8,037 ) (5,375 ) Other (expense) income, net (15 ) 192 (185 ) (1,369 ) Income before provision for income taxes $ 10,884 $ 12,344 $ 29,554 $ 29,697 (1) Other includes revenue and the related costs from the sale of solutions and services not directly attributable to a reportable segment.

Summary of Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
Unaudited interim consolidated financial statements	Unaudited interim consolidated financial statements The accompanying interim consolidated financial statements have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission ("SEC") for interim financial reporting. These consolidated statements are unaudited and, in the opinion of management, include all adjustments (consisting of normal recurring adjustments and accruals) necessary to state fairly the consolidated balance sheets, consolidated statements of comprehensive income, consolidated statements of cash flows and consolidated statements of stockholders’ equity, for the periods presented in accordance with accounting principles generally accepted in the United States ("GAAP"). The consolidated balance sheet at December 31, 2015 , has been derived from the audited consolidated financial statements at that date. Operating results and cash flows for the nine months ended September 30, 2016 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2016 , or any other future period. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted in accordance with the rules and regulations for interim reporting of the SEC. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2015 , and other forms filed with the SEC from time to time.
Basis of consolidation	Basis of consolidation The consolidated financial statements include the accounts of Blackbaud, Inc. and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of estimates	Use of estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. On an ongoing basis, we reconsider and evaluate our estimates and assumptions, including those that impact revenue recognition, long-lived and intangible assets including goodwill, stock-based compensation, the provision for income taxes, deferred taxes, capitalization of software development costs and related amortization, our allowances for sales returns and doubtful accounts, deferred sales commissions and professional services costs, valuation of derivative instruments, accounting for business combinations and loss contingencies. Changes in the facts or circumstances underlying these estimates could result in material changes and actual results could materially differ from these estimates.
Revenue recognition	Revenue recognition Our revenue is primarily generated from the following sources: (i) charging for the use of our software solutions in cloud-based and hosted environments; (ii) providing software maintenance and support services; (iii) providing professional services including implementation, training, consulting, analytic, hosting and other services; (iv) providing transaction and payment processing services; and (v) selling perpetual licenses of our software solutions. We recognize revenue when all of the following conditions are met: • Persuasive evidence of an arrangement exists; • The solutions or services have been delivered; • The fee is fixed or determinable; and • Collection of the resulting receivable is probable. Determining whether and when these criteria have been met can require significant judgment and estimates. We deem acceptance of a contract to be evidence of an arrangement. Delivery of our services occurs when the services have been performed. Delivery of our solutions occurs when the solution is shipped or transmitted, and title and risk of loss have transferred to the customers. Our typical arrangements do not include customer acceptance provisions; however, if acceptance provisions are provided, delivery is deemed to occur upon acceptance. We consider the fee to be fixed or determinable unless the fee is subject to refund or adjustment or is not payable within our standard payment terms. Payment terms greater than 90 days are considered to be beyond our customary payment terms. Collection is deemed probable if we expect that the customer will be able to pay amounts under the arrangement as they become due. If we determine that collection is not probable, we defer revenue recognition until collection. Revenue is recognized net of actual and estimated sales returns and allowances. We follow guidance provided in ASC 605-45, Principal Agent Considerations , which states that determining whether a company should recognize revenue based on the gross amount billed to a customer or the net amount retained is a matter of judgment that depends on the facts and circumstances of the arrangement and that certain factors should be considered in the evaluation. Subscriptions We provide software solutions to customers which are available for use in cloud-based subscription arrangements without licensing perpetual rights to the software (“cloud-based solutions”). Revenue from cloud-based solutions is recognized ratably beginning on the activation date over the term of the agreement, which generally ranges from one to three years. Any revenue related to upfront activation or set-up fees is deferred and recognized ratably over the estimated period that the customer benefits from the related cloud-based solution. Direct and incremental costs related to upfront activation or set-up activities for cloud-based solutions are capitalized until the cloud-based solution is deployed and in use, and then expensed ratably over the estimated period that the customer benefits from the related cloud-based solution. We provide hosting services to customers who have purchased perpetual rights to certain of our software solutions (“hosting services”). Revenue from hosting services, online training programs as well as subscription-based analytic services such as data enrichment and data management services, is recognized ratably beginning on the activation date over the term of the agreement, which generally ranges from one to three years. Any related set-up fees are recognized ratably over the estimated period that the customer benefits from the related hosting service. The estimated period of benefit is evaluated on an annual basis using historical customer retention information by solution or service. For arrangements that have multiple elements and do not include software licenses, we allocate arrangement consideration at the inception of the arrangement to those elements that qualify as separate units of accounting. The arrangement consideration is allocated to the separate units of accounting based on relative selling price method in accordance with the selling price hierarchy, which includes: (i) vendor specific objective evidence (“VSOE”) of fair value if available; (ii) third-party evidence (“TPE”) if VSOE is not available; and (iii) best estimate of selling price (“BESP”) if neither VSOE nor TPE is available. In general, we use VSOE to allocate the selling price to subscription and service deliverables. We offer certain payment processing services with the assistance of third-party vendors. In general, when we are the principal in a transaction based on the predominant weighting of factors identified in ASC 605-45, we record the revenue and related costs on a gross basis. Otherwise, we net the cost of revenue associated with the service against the gross amount billed to the customer and record the net amount as revenue. Revenue from transaction processing services is recognized when the service is provided and the amounts are determinable. Revenue directly associated with processing donations for customers are included in subscriptions revenue. Maintenance We recognize revenue from maintenance services ratably over the term of the arrangement, generally one year at contract inception with annual renewals thereafter. Maintenance contracts are at rates that vary according to the level of the maintenance program associated with the software solution and are generally renewable annually. Maintenance contracts may also include the right to unspecified solution upgrades on an if-and-when available basis. Certain incremental support services are sold in prepaid units of time and recognized as revenue upon their usage. Services We generally bill consulting, installation and implementation services based on hourly rates plus reimbursable travel-related expenses. Revenue is recognized for these services over the period the services are delivered. We recognize analytic services revenue from donor prospect research engagements, the sale of lists of potential donors, benchmarking studies and data modeling service engagements upon delivery. In arrangements where we provide customers the right to updated information during the contract period, revenue is recognized ratably over the contract period. We sell fixed-rate programs, which permit customers to attend unlimited training over a specified contract period, typically one year, subject to certain restrictions, and revenue in those cases is recognized ratably over the contract period. Additionally, we sell training at a fixed rate for each specific class at a per attendee price or at a packaged price for several attendees, and recognize the related revenue upon the customer attending and completing training. License fees We sell perpetual software licenses with maintenance, varying levels of professional services and, in certain instances, with hosting services. We allocate revenue to each of the elements in these arrangements using the residual method under which we first allocate revenue to the undelivered elements, typically the non-software license components, based on VSOE of fair value of the various elements. We determine VSOE of fair value of the various elements using different methods. VSOE of fair value for maintenance services associated with software licenses is based upon renewal rates stated in the arrangements with customers, which demonstrate a consistent relationship of maintenance pricing as a percentage of the contractual license fee. VSOE of fair value of professional services and other solutions and services is based on the average selling price of these same solutions and services to other customers when sold on a stand-alone basis. Any remaining revenue is allocated to the delivered elements, which is normally the software license in the arrangement. In general, revenue is recognized for software licenses upon delivery to our customers. When a software license is sold with software customization services, generally the services are to provide the customer assistance in creating special reports and other enhancements that will improve operational efficiency and/or help to support business process improvements. These services are generally not essential to the functionality of the software and the related revenues are recognized either as the services are delivered or upon completion. However, when software customization services are considered essential to the functionality of the software, we recognize revenue for both the software license and the services using the percentage-of-completion method. Deferred revenue To the extent that our customers are billed for the above described solutions and services in advance of delivery, we record such amounts in deferred revenue. Generally, our subscription and maintenance customers are billed one year in advance.
Fair value measurements	Fair value measurements We measure certain financial assets and liabilities at fair value on a recurring basis, including derivative instruments. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. An active market is defined as a market in which transactions for the asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis. We use a three-tier fair value hierarchy to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows: • Level 1 - Quoted prices for identical assets or liabilities in active markets; • Level 2 - Quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and • Level 3 - Valuations derived from valuation techniques in which one or more significant inputs are unobservable. Our financial assets and liabilities are classified in their entirety within the hierarchy based on the lowest level of input that is significant to fair value measurement. Changes to a financial asset's or liability's level within the fair value hierarchy are determined as of the end of a reporting period. All methods of assessing fair value result in a general approximation of value, and such value may never actually be realized.
Earnings per share	Earnings per share We compute basic earnings per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income available to common stockholders by the weighted average number of common shares and dilutive potential common shares outstanding during the period. Diluted earnings per share reflect the assumed exercise, settlement and vesting of all dilutive securities using the “treasury stock method” except when the effect is anti-dilutive. Potentially dilutive securities consist of shares issuable upon the exercise of stock options, settlement of stock appreciation rights and vesting of restricted stock awards and units.
Recently adopted accounting pronouncements	Recently adopted accounting pronouncements In September 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments (ASU 2015-16) . ASU 2015-16 requires for acquirers in business combinations to recognize adjustments to provisional amounts identified during measurement periods in the reporting periods in which adjusted amounts are determined. The update requires that acquirers record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization or other income effects, if any, resulting from changes in provisional amounts, calculated as if the accounting had been completed at acquisition date. The update also requires separate income statement presentation or note disclosure of amounts recorded in current period earnings by line item that would have been recorded in previous reporting periods if the provisional amount adjustments had been recognized at the acquisition date (requirements to retrospectively account for those adjustments have been eliminated). The guidance is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Amendments in this update should be applied prospectively to adjustments to provisional amounts that occur after its effective date, with earlier application permitted for financial statements that have not been issued. We adopted ASU 2015-16 on January 1, 2016. See Note 3 to these consolidated financial statements for details of any immaterial measurement period adjustments. In April 2015, the FASB issued ASU No. 2015-05, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer's Accounting for Fees Paid in a Cloud Computing Arrangement (ASU 2015-05) . The amendments in this update provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the update specifies that the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. The update further specifies that the customer should account for a cloud computing arrangement as a service contract if the arrangement does not include a software license. An entity can elect to adopt the amendments either (1) prospectively to all arrangements entered into or materially modified after the effective date or (2) retrospectively. We adopted ASU 2015-05 on January 1, 2016 on a prospective basis and it did not have a material impact on our consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest - Simplifying the Presentation of Debt Issuance Costs (ASU 2015-03) . ASU 2015-03 sets forth a requirement that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs is not affected by the amendments in this update. An entity should apply the new guidance on a retrospective basis, wherein the balance sheet of each individual period presented is adjusted to reflect the period-specific effects of applying the new guidance. We adopted ASU 2015-03 on January 1, 2016 and retrospectively restated "other assets" and "debt, net of current portion", which had the effect of reducing each of those respective line items in our December 31, 2015 consolidated balance sheet by approximately $0.5 million . In March 2016, the FASB issued ASU 2016-09, Compensation — Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting (ASU 2016-09) . The new guidance requires excess tax benefits and tax deficiencies to be recorded in the income statement when the awards vest or are settled and provides an accounting policy election to account for forfeitures as they occur. In addition, cash flows related to excess tax benefits will no longer be separately classified as a financing activity apart from other income tax cash flows within operating activities. The standard also allows entities to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting and clarifies that all cash payments made on an employee’s behalf for withheld shares should be presented as a financing activity on the statements of cash flows. The new standard is effective for fiscal years beginning after December 15, 2016, with early adoption permitted. We early adopted ASU 2016-09 during the three months ended September 30, 2016, which requires us to reflect any adjustments as of January 1, 2016, the beginning of the annual period that includes the interim period of adoption. Upon adoption, we elected to account for forfeitures as they occur using a modified retrospective transition method, which resulted in a cumulative-effect adjustment of $0.9 million to reduce our January 1, 2016 opening retained earnings balance. The following table summarizes the impact to our consolidated balance sheet, including the net amount charged to retained earnings as of January 1, 2016: (dollars in thousands) As of January 1, 2016 Balance sheet location Amount Decrease in deferred tax liabilities related to the cumulative effect adjustment from our election to recognize forfeitures as they occur rather than applying an estimated forfeiture rate Deferred tax liability $ (606 ) Increase in additional paid-in capital resulting from our election to recognize forfeitures as they occur Additional paid-in capital $ 1,540 Net charge to retained earnings for cumulative effect adjustment from adoption of ASU 2016-09 Retained earnings $ (934 ) We elected to retrospectively apply the changes in presentation to the statements of cash flows and no longer classify excess tax benefits as a financing activity, which increased both net cash provided by operating activities and net cash used in financing activities by $1.5 million for the nine months ended September 30, 2015. The presentation requirements for cash flows related to employee taxes paid for withheld shares increased both net cash provided by operating activities and net cash used in financing activities for the nine months ended September 30, 2015 by $2.7 million , as such cash flows were historically presented within operating cash flows. Adoption of the new standard resulted in the recognition of additional stock-based compensation expense of approximately $0.6 million and $1.0 million for the three and nine months ended September 30, 2016, respectively, as well as the recognition of excess tax benefits in our provision for income taxes rather than paid-in capital of $1.6 million and $4.3 million for the three and nine months ended September 30, 2016, respectively. The adoption of ASU 2016-09 impacted our previously reported quarterly results for fiscal year 2016 as follows: Consolidated balance sheets: (dollars in thousands) As of March 31, 2016 As of June 30, 2016 As Reported As Adjusted As Reported As Adjusted Additional paid-in capital $ 285,376 $ 285,606 $ 294,810 $ 294,019 Retained earnings $ 134,192 $ 134,500 $ 136,338 $ 137,893 Consolidated statements of comprehensive income: (dollars in thousands, except per share amounts) Three months ended March 31, 2016 Three months ended June 30, 2016 As Reported As Adjusted As Reported As Adjusted Income tax provision $ 2,664 $ 1,595 $ 3,598 $ 1,778 Net income $ 4,995 $ 6,237 $ 7,813 $ 9,060 Basic earnings per share $ 0.11 $ 0.14 $ 0.17 $ 0.20 Diluted earnings per share $ 0.11 $ 0.13 $ 0.17 $ 0.19 Diluted weighted average shares outstanding 46,757,458 47,064,164 46,927,626 47,263,844 Consolidated statements of cash flows: (dollars in thousands) Three months ended March 31, 2016 Six months ended June 30, 2016 As Reported As Adjusted As Reported As Adjusted Net cash provided by operating activities $ 104 $ 6,757 $ 37,987 $ 48,753 Net cash provided by (used in) financing activities $ 9,546 $ 2,893 $ (13,852 ) $ (24,618 )
Recently issued accounting pronouncements	Recently issued accounting pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (ASU 2016-02) . ASU 2016-02 will require lessees to record most leases on their balance sheets but recognize expenses in the income statement in a manner similar to current guidance. The updated guidance also eliminates certain real estate-specific provisions and changes the guidance on sale-leaseback transactions, initial direct costs and lease executory costs for all entities. For lessors, the standard modifies the classification criteria and the accounting for sales-type and direct financing leases. All entities will classify leases to determine how to recognize lease-related revenue and expense. Classification will continue to affect amounts that lessors record on the balance sheet. ASU 2016-02 is effective for annual periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted. Upon adoption, entities will be required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. We expect ASU 2016-02 will impact our consolidated financial statements and are currently evaluating the extent of the impact that implementation of this standard will have on adoption. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU 2014-09) . ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will replace most existing revenue recognition guidance in GAAP when it becomes effective. ASU 2014-09 was originally effective for fiscal years and interim periods within those years beginning after December 15, 2016. An entity should apply ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying the ASU recognized as an adjustment to the opening balance of retained earnings at the date of initial application. In July 2015, the FASB decided to delay the effective date of the new standard for one year. The new standard now requires application no later than annual reporting periods beginning after December 15, 2017, including interim reporting periods therein; however, public entities are permitted to elect to early adopt the new standard as of the original effective date. In March 2016, the FASB finalized amendments to the guidance in the new standard to clarify whether an entity is a principal or an agent in a revenue transaction. In April 2016, the FASB finalized additional amendments to the guidance in the new standard to clarify the accounting for licenses of intellectual property and identifying performance obligations. We expect the adoption of ASU 2014-09 will impact our consolidated financial statements. We are currently evaluating implementation methods and the extent of the impact that implementation of this standard and the recently issued clarifying amendments will have upon adoption.
