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 statementstatements of stockholders’ equity, for the periods presented in accordance with accounting principles generally accepted in the United States ("U.S.") ("GAAP"). The consolidated balance sheet at December 31, 2018, has been derived from the audited consolidated financial statements at that date. Operating results and cash flows for the threesix months ended March 31,June 30, 2019 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2019, 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, 2018, and other forms filed with the SEC from time to time.

The consolidated financial statements include the accounts of Blackbaud, Inc. and its wholly-ownedwholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

We report our operating results and financial information in one operating and reportable segment. Our chief operating decision maker uses consolidated financial information to make operating decisions, assess financial performance and allocate resources. Our chief operating decision maker is our chief executive officer ("CEO").

We adopted ASU 2016-02 as of January 1, 2019 using the transition method that allowed us to initially apply the guidance at the adoption date of January 1, 2019 without adjusting comparative periods presented. We elected to use the package of practical expedients that allowed us to not reassess: (1) whether any expired or existing contracts are or contain leases, (2) lease classification for any expired or existing leases and (3) initial direct costs for any existing leases. We did not elect to use the hindsight practical expedient, which permits entities to use hindsight in determining the lease term and assessing

to use the hindsight practical expedient, which permits entities to use hindsight in determining the lease term and assessing impairment. Additionally, we elected not to apply the recognition requirements of the new lease accounting standard to short-term leases. Adopting ASU 2016-02 had a material impact on our consolidated balance sheet as of January 1, 2019, as we recognized $121.6 million of lease liabilities and $113.4 million of right-of-use ("ROU") assets for those leases classified as operating leases.

Except for the accounting policy added for leases below as a result of adopting ASU 2016-02, there have been no changes to our significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2018, filed with the SEC on February 20, 2019, that have had a material impact on our consolidated financial statement.statements.

We determine if an arrangement is a lease at inception. Operating leases are included in operating lease ROU assets, accrued expense and other current liabilities, and operating lease liabilities, net of current portion in our consolidated balance sheet as of March 31,June 30, 2019.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The operating lease ROU asset also includes any initial direct costs and lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments related to our operating leases is recognized on a straight-line basis over the lease term. We have lease agreements with lease and non-lease components, which are generally accounted for separately. We do not recognize short-term leases (those that, at the commencement date, have a lease term of 12 months or less) on our consolidated balance sheets. Variable lease payments, which are primarily comprised of common-area maintenance, utilities and real estate taxes that are passed on from the lessor in proportion to the space leased by us, are recognized in operating expenses in the period in which the obligation for those payments is incurred.

On January 2, 2019, we acquired all of the outstanding equity securities, including all voting equity interests, of YourCause Holdings, LLC, a Delaware limited liability company ("YourCause"), pursuant to a purchase agreement and plan of merger. The acquisition expands our footprint in corporate social responsibility and employee engagement and enhances our position as a leader in providing solutions to both nonprofit organizations and for-profit companies committed to addressing social issues. We acquired the equity securities for an aggregate purchase price of $157.7 million in cash, subject to certain adjustments set forth in the agreement and plan of merger. The purchase price and related expenses were funded primarily through borrowings under the 2017 Credit Facility (as defined below). As a result of the acquisition, YourCause has become a wholly-ownedwholly owned subsidiary of ours. The operating results of YourCause have been included in our consolidated financial statements from the date of acquisition. During the three and six months ended March 31,June 30, 2019, we incurred insignificant acquisition-related expenses associated with the acquisition, which were recorded in general and administrative expense.

The fair values assigned to the assets acquired and liabilities assumed in the table below are based on our best estimates and assumptions as of the reporting date and are considered preliminary pending finalization. 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. The assets and liabilities, pending finalization, include the valuation of intangible assets as well as the assumed deferred revenue and deferred income tax balances.

The estimated fair value of accounts receivable acquired approximates the contractual value of $4.1 million and $54.7 million of the goodwill arising in the acquisition is deductible for income tax purposes. The estimated goodwill recognized is attributable primarily to the opportunities for expected synergies from combining the operations and assembled workforce of YourCause. During the six months ended June 30, 2019, we recorded an insignificant measurement period adjustment to the estimated fair value of the YourCause assets acquired and liabilities assumed following the receipt of new information. The adjustment resulted in an increase to net working capital, excluding deferred revenue, with the corresponding offset to goodwill.

The estimated fair values of the intangible assets were based on variations of the income approach, which estimates fair value based upon the present value of cash flows that the assets are expected to generate, and which included the relief-from-royalty method, incremental cash flow method, including the comparative (with and without) method and multi-period 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 assets are being amortized on an accelerated basis. Marketing assets are being amortized on a straight-line basis. The non-compete agreements were fully amortized as of March 31, 2019, based on the insignificance of the acquired assets.

We determined that the impact of this acquisition was not material to our consolidated financial statements; therefore, separate presentation of revenue and earnings since the acquisition date and pro forma information are not required nor included herein.

The change in goodwill during the threesix months ended March 31,June 30, 2019, consisted of the following:

We compute basic earnings (loss) per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) 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 (loss) 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. Diluted loss per share for the three months ended March 31, 2019 is the same as basic loss per share as there is a net loss in the period and inclusion of potentially dilutive securities is anti-dilutive.

We use a three-tier fair value hierarchy to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows:

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 March 31,June 30, 2019 and December 31, 2018, due to the immediate or short-term maturity of these instruments.

We did not transfer any assets or liabilities among the levels within the fair value hierarchy during the threesix months ended March 31,June 30, 2019. Additionally, we did not hold any Level 3 assets or liabilities during the threesix months ended March 31,June 30, 2019.

Assets and liabilities that are measured at fair value on a non-recurring basis include intangible assets, goodwill and operating lease ROU assets, which are recognized at fair value during the period in which an acquisition is completed or at lease commencement, 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 and operating lease ROU assets, are based on Level 3 unobservable inputs. In the event of an impairment, we determine the fair value of the intangible assets other than goodwill 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. For goodwill impairment testing, we estimate fair value using market-based methods including the use of market capitalization and consideration of a control premium.

During the threesix months ended March 31,June 30, 2019, we recorded $1.3 million in impairments of operating lease ROU assets associated with certain leased office spaces we ceased using as part of our facilities optimization restructuring. These impairments were recorded as restructuring expense on our consolidated statements of comprehensive income. See Note 15 to these consolidated financial statements for additional details regarding our facilities optimization restructuring.

There were no non-recurring fair value adjustments to intangible assets and goodwill during the threesix months ended March 31, 2019.June 30, 2019, except for an insignificant business combination accounting adjustment to the initial fair value estimates of the YourCause 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. We record any measurement period adjustments to the fair value of assets acquired and liabilities assumed, with the corresponding offset to goodwill.

The following table summarizes our debt balances and the related weighted average effective interest rates, which includes the effect of interest rate swap agreements.

On January 2, 2019, we acquired YourCause for $157.7 million in cash, subject to certain adjustments set forth in the agreement and plan of merger. We financed the acquisition with a revolving credit loan under the 2017 Credit Facility.

We generally use derivative instruments to manage our variable interest rate risk. In July 2017, we entered into an interest rate swap agreement (the "July 2017 Swap Agreement"), which effectively converts portions of our variable rate debt under our credit facilitythe 2017 Credit Facility to a fixed rate for the term of the July 2017 Swap Agreement. The notional value of the July 2017 Swap Agreement was $150.0 million with an effective date beginning in July 2017 through July 2021. We designated the July 2017 Swap Agreement as a cash flow hedge at the inception of the contract.

In February 2018, we entered into an additional interest rate swap agreement (the "February 2018 Swap Agreement"), which effectively converts portions of our variable rate debt under our credit facilitythe 2017 Credit Facility to a fixed rate for the term of the February 2018 Swap Agreement. The notional value of the February 2018 Swap Agreement was $50.0 million with an effective date beginning in February 2018 through June 2021. We designated the February 2018 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:

The effects of derivative instruments in cash flow hedging relationships were as follows:

We have operating leases for corporate offices, subleased offices and certain equipment and furniture. Our leases have remaining lease terms of less than 1 year to 2019 years, some of which include options to extend the leases for up to 5 years. We do not have lease agreements with residual value guarantees, sale leaseback terms or material restrictive covenants.

In May 2016, we entered into a lease agreement for our New Headquarters Facility in Charleston, South Carolina. There are two phases for construction of the New Headquarters Facility. Phase One included a building with approximately 172,000 rentable square feet, which we began using in April 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. The lease agreement expires in April 2038 and provides for four renewal periods of five years each at a base rent equal to the then prevailing market rate for comparable buildings.

We continue to lease our former headquarters facility, now called our Customer Operations Center, in Charleston, South Carolina. The lease expires in October 2023 and has two five-year renewal options. We also have a lease for office space in Austin, Texas which expires in September 2023 and has two five-year renewal options.

For each of the leases discussed above, we have not included the renewal options in the lease terms for calculating the lease liability as the renewal options allow us to maintain operational flexibility and we are not reasonably certain we will exercise these options at this time.

As of March 31,June 30, 2019, we had additional operating leases, primarily for office space, that have not yet commenced with future rent payments of $9.3$6.5 million. These operating leases will commence during fiscal year 2019 with lease terms of two years.

During the threesix months ended March 31,June 30, 2019, we recorded $1.3 million in impairments of operating lease ROU assets associated with certain leased office spaces we ceased using as part of our facilities optimization restructuring. These impairments were recorded as restructuring expense on our consolidated statements of comprehensive income. See Note 15 to these consolidated financial statements for additional details regarding our facilities optimization restructuring.

Total rent expense as determined under ASC 840 for the three and six months ended March 31,June 30, 2018 was $4.5 million.

As determined under ASC 840, the future minimum lease payments related to lease agreements with a remaining noncancelable term in excess of one year, net of related sublease commitments and lease incentives, as of December 31, 2018 were as follows:

The term loans under the 2017 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 2017 Credit Facility in June 2022.

We have contractual obligations for third-party technology used in our solutions and for other services we purchase as part of our normal operations. In certain cases, these arrangements require a minimum annual purchase commitment by us. As of March 31,June 30, 2019, the remaining aggregate minimum purchase commitment under these arrangements was approximately $111.4$106.5 million through 2023.

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.

We are subject to legal proceedings and claims that arise in the ordinary course of business. We make a provision for a loss contingency when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. Unless otherwise specifically disclosed in this note, we have determined as of March 31,June 30, 2019, that no provision for liability nor disclosure is required

related to any claim against us because (a) there is not a reasonable possibility that a loss exceeding amounts already recognized (if any) may be incurred with respect to such claim; (b) a reasonably possible loss or range of loss cannot be estimated; or (c) such estimate is immaterial.

All legal costs associated with litigation are expensed as incurred. Litigation is inherently unpredictable. However, we believe that we have valid defenses with respect to the legal matters pending against us. It is possible, nevertheless, that our consolidated financial position, results of operations or cash flows could be negatively affected in any particular period by an unfavorable resolution of one or more of such proceedings, claims or investigations.

Our income tax benefitprovision (benefit) and effective income tax rates, including the effects of period-specific events, were:
