Tyler Technologies, Inc.
Notes to Condensed Consolidated Financial Statements
(Unaudited)
(Tables in thousands, except per share data)

(1)    Basis of Presentation
We prepared the accompanying condensed consolidated financial statements following the requirements of the Securities and Exchange Commission (“SEC”) and accounting principles generally accepted in the United States, or GAAP, for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP can be condensed or omitted for interim periods. Balance sheet amounts are as of September 30, 2018,2019, and December 31, 2017,2018, and operating result amounts are for the three and nine months ended September 30, 2018,2019, and 2017,2018, respectively, and include all normal and recurring adjustments that we considered necessary for the fair summarized presentation of our financial position and operating results. As these are condensed financial statements, one should also read the financial statements and notes included in our latest Form 10-K for the year ended December 31, 2017.2018. Revenues, expenses, assets and liabilities can vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be the same as those for the full year.
Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions, and other events and circumstances from non-owner sources and includes all components of net income (loss) and other comprehensive income (loss). We had no items of other comprehensive income (loss) for the three and nine months ended September 30, 20182019, and 2017.
Effective January 1, 2018, we adopted the requirements of Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers, utilizing the full retrospective approach as discussed in Note 2 - Accounting Standards and Significant Accounting Policies. All amounts and disclosures set forth in this Form 10-Q have been updated to comply with the new standard, as indicated by the "as adjusted" footnote.2018.

Except for the accounting policies for revenueleases recognition and deferred commissions that were adjusted as a result of adopting ASU No. 2014-09,2016-02, Leases ("Topic 842"), there have been no changes to our significant accounting policies described in the Annual Report on Form 10-K for the year ended December 31, 2017,2018, filed with the SEC on February 21, 2018,20, 2019, that have had a material impact on our condensed consolidated financial statements and related notes.
USE OF ESTIMATES
The preparation of our financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include revenue recognition, determining the nature and timing of satisfaction of performance obligations, and determining the standalone selling price (“SSP”("SSP") of performance obligations, variable consideration, and other obligations such as returns and refunds; loss contingencies; the estimated useful life of deferred commissions; the carrying amount and estimated useful lives of intangible assets; the carrying amount of operating lease right-of-use assets and operating lease liabilities; determining share-based compensation expense; the valuation allowance for receivables; and determining the potential outcome of future tax consequences of events that have been recognized on our consolidated financial statements or tax returns. Actual results could differ from estimates.


REVENUE RECOGNITION
Nature of Products and Services
We provide integrated software systems and related services for the public sector, with a focus on local governments. We develop and market a broad line of software solutions and services to address the information technology (“IT”) needs of cities, counties, schools and other local government entities. In addition, we provide professional IT services, including software and hardware installation, data conversion, training, and for certain customers, product modifications, along with continuing maintenance and support for customers using our systems. We also provide subscription-based services such as software as a service (“SaaS”) arrangements, which utilize the Tyler private cloud, and electronic document filing solutions (“e-filing”). In addition, we provide property appraisal outsourcing services for taxing jurisdictions.Services:
We earn revenue from software licenses, royalties, subscription-based services, software services, post-contract customer support (“PCS” or “maintenance”), hardware, and appraisal services. Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We determine revenue recognition through the following steps:
Identification of the contract, or contracts, with a customer
Identification of the performance obligations in the contract
Determination of the transaction price


Allocation of the transaction price to the performance obligations in the contract
Recognition of revenue when, or as, we satisfy a performance obligation
Most of our software arrangements with customers contain multiple performance obligations that range from software licenses, installation, training, and consulting to software modification and customization to meet specific customer needs (services), hosting, and PCS. For these contracts, we account for individual performance obligations separately when they are distinct. We evaluate whether separate performance obligations can be distinct or should be accounted for as one performance obligation. Arrangements that include software services, such as training or installation, are evaluated to determine whether thosethe customer can benefit from the services either on their own or together with other resources readily available to the customer and whether the services are essential toseparately identifiable from other promises in the product’s functionality.contract. The transaction price is allocated to the distinct performance obligations on a relative SSP basis. We determine the SSP based on our overall pricing objectives, taking into consideration market conditions and other factors, including the value of our contracts, the applications sold, customer demographics, and the number and types of users within our contracts. Revenue is recognized net of allowances for sales adjustments and any taxes collected from customers, which are subsequently remitted to governmental authorities.
Software Arrangements:
Software Licenses and Royalties
Many of our software arrangements involve “off-the-shelf” software. We recognize the revenue allocable to "off-the-shelf" software licenses and specified upgrades at a point in time when control of the software license transfers to the customer, unless the software is not considered distinct. We consider off-the-shelf software to be distinct when it can be added to an arrangement with minor changes in the underlying code, it can be used by the customer for the customer’s purpose upon installation and remaining services such as training are not considered essential to the product's functionality.
For arrangements that involve significant production, modification or customization of the software, or where software services are otherwise not considered distinct, we recognize revenue over time by measuring progress-to-completion. We measure progress-to-completion primarily using labor hours incurred as it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. These arrangements are often implemented over an extended period and occasionally require us to revise total cost estimates. Amounts recognized in revenue are calculated using the progress-to-completion measurement after giving effect to any changes in our cost estimates. Changes to total estimated contract costs, if any, are recorded in the period they are determined. Estimated losses on uncompleted contracts are recorded in the period in which we first determine that a loss is apparent.
Software license fees are billed in accordance with the contract terms. Typically, a majority of the fee is due when access to the software license is made available to the customer and the remainder of the fee due over a passage of time stipulated by the contract. We record amounts that have been invoiced in accounts receivable and in deferred revenue or revenues, depending on whether the revenue recognition criteria have been met.


We recognize royalty revenue when the sale occurs under the terms of our third-party royalty arrangements. Currently, our third-party royalties are recognized on an estimated basis and are trued up when we receive notice of amounts we are entitled to receive. Typically, we receive notice of royalty revenues we are entitled to and billed on a quarterly basis in the quarter immediately following the royalty reporting period.
Software Services
As noted above, some of our software arrangements include services considered essential or require significant customization to meet the customer's desired functionality. For these software arrangements, both the software licenses and related software services revenue are not distinct and are recognized over time using the progress-to-completion method. We measure progress-to-completion primarily using labor hours incurred as it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. Contract fees are typically billed on a milestone basis as defined within contract terms. We record amounts that have been invoiced in accounts receivable and in deferred revenue or revenues, depending on whether the revenue recognition criteria have been met. When software services are distinct, the fee allocable to the service element is recognized over the time we perform the services and is billed on a time and material basis.
Post-Contract Customer Support
Our customers generally enter into PCS agreements when they purchase our software licenses. PCS includes telephone support, bug fixes, and rights to upgrades on a when-and-if available basis. PCS is considered distinct when purchased with our software licenses. Our PCS agreements are typically renewable annually. PCS is recognized over time on a straight-line basis over the period the PCS is provided. All significant costs and expenses associated with PCS are expensed as incurred.
Computer Hardware Equipment
Revenue allocable to computer hardware equipment is recognized at a point in time when control of the equipment is transferred to the customer.
Subscription-Based Services:
Subscription-based services consist of revenues derived from SaaS arrangements, which utilize the Tyler private cloud, and electronic filing transactions. Revenue from subscription-based services is generally recognized over time on a ratable basis over the contract term, beginning on the date that our service is made available to the customer. Our subscription contracts are generally three to five years or longer in length, billed annually in advance, and non-cancelable.
For SaaS arrangements, we evaluate whether the customer has the contractual right to take possession of our software at any time during the hosting period without significant penalty and whether the customer can feasibly maintain the software on the customer’s hardware or enter into another arrangement with a third-party to host the software. We allocate contract value to each performance obligation of the arrangement that qualifies for treatment as a distinct element based on estimated SSP. When it is determined that software is distinct and the customer has the ability to take control of the software, we recognize revenue allocable to the software license fee when access to the software license is made available to the customer. We recognize hosting services ratably over the term of the arrangement, which range from one to ten years but are typically for a period of three to five years. For software services associated with certain SaaS arrangements, we have concluded that the services are not distinct, and we recognize the revenue ratably over the remaining contractual period once we have provided the customer access to the software. We record amounts that have been invoiced in accounts receivable and in deferred revenue or revenues, depending on whether the revenue recognition criteria have been met.
Electronic filing transaction fees primarily pertain to documents filed with the courts by attorneys and other third-parties via our e-filing services and retrieval of filed documents via our access services. For each document filed with a court, the filer generally pays a transaction fee and a court filing fee to us and we remit a portion of the transaction fee and the filing fee to the court. We record as revenue the transaction fee, while the portion of the transaction fee remitted to the courts is recorded as cost of sales as we are acting as a principal in the arrangement. Court filing fees collected on behalf of the courts and remitted to the courts are recorded on a net basis and thus do not affect the statement of comprehensive income. For e-filing transaction fees, we have the right to charge the customer an amount that directly corresponds with the value to the customer of our performance to date. Therefore, we recognize revenue for these services over time based on the amount billable to the customer in accordance with the 'as invoiced' practical expedient in ASC 606-10-55-18. In some cases, we are paid on a fixed fee basis and recognize the revenue ratably over the contractual period.


Costs of performing services under subscription-based arrangements are expensed as incurred, except for certain direct and incremental contract origination and set-up costs associated with SaaS arrangements. Such direct and incremental costs are capitalized and amortized ratably over the useful life.
Appraisal Services:
For our property appraisal projects, we recognize revenue using the progress-to-completion method since many of these projects are implemented over one to three-year periods and consist of various unique activities. Appraisal services require a significant level of integration and interdependency with various individual service components; therefore, the service components are not considered distinct. Appraisal services are recognized over time by measuring progress-to-completion primarily using labor hours incurred as it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. These arrangements are often implemented over an extended period and occasionally require us to revise total cost estimates. Amounts recognized in revenue are calculated using the progress-to-completion measurement after giving effect to any changes in our cost estimates. Changes to total estimated contract costs, if any, are recorded in the period they are determined. Estimated losses on uncompleted contracts are recorded in the period in which we first determine that a loss is apparent. Contract fees are typically billed on a milestone basis as defined within contract terms. We record amounts that have been invoiced in accounts receivable and in deferred revenue or revenues, depending on whether the revenue recognition criteria have been met.
Significant Judgments:
Our contracts with customers often include multiple performance obligations to a customer. When a software arrangement (traditional(license or subscription) includes both software licenses and software services, judgment is required to determine whether the software license is considered distinct and accounted for separately, or not distinct and accounted for together with the software services and recognized over time.
The transaction price is allocated to the separate performance obligations on a relative SSP basis. We determine the SSP based on our overall pricing objectives, taking into consideration market conditions and other factors, including the value of our contracts, the applications sold, customer demographics, and the number and types of users within our contracts.We use a range of amounts to estimate SSP when we sell each of the products and services separately and need to determine whether there is a discount to be allocated based on the relative SSP of the various products and services. In instances where SSP is not directly observable, such as when we do not sell the product or service separately, we determine SSP using the expected cost-plus margin approach.
For arrangements that involve significant production, modification or customization of the software, or where software services otherwise cannot be considered distinct, we recognize revenue as control is transferred to the customer over time using progress-to-completion methods. Depending on the contract, we measure progress-to-completion primarily using labor hours incurred, or value added. The progress-to-completion method generally results in the recognition of reasonably consistent profit margins over the life of a contract because we can provide reasonably dependable estimates of contract billings and contract costs. We use the level of profit margin that is most likely to occur on a contract. If the most likely profit margin cannot be precisely determined, the lowest probable level of profit margin in the range of estimates is used until the results can be estimated more precisely. These arrangements are often implemented over an extended time period and occasionally require us to revise total cost estimates. Amounts recognized in revenue are calculated using the progress-to-completion measurement after giving effect to any changes in our cost estimates. Changes to total estimated contract costs, if any, are recorded in the period they are determined. Estimated losses on uncompleted contracts are recorded in the period in which we first determine that a loss is apparent.
Typically, the structure of our arrangements does not give rise to variable consideration. However, in those instances whereby variable consideration exists, we include in our estimates additional revenue for variable consideration when we believe we have an enforceable right, the amount can be estimated reliably and its realization is probable.
Refer to Note 1213 - Disaggregation of Revenue for further information, including the economic factors that affect the nature, amount, timing, and uncertainty of revenue and cash flows of our various revenue categories.


Contract Balances:
Accounts receivable and allowance for doubtful accounts
Timing of revenue recognition may differ from the timing of invoicing to customers. We record an unbilled receivable when revenue is recognized prior to invoicing, or deferred revenue when revenue is recognized subsequent to invoicing. For multi-year agreements, we generally invoice customers annually at the beginning of each annual coverage period. We record an unbilled receivable related to revenue recognized for on-premises licenses as we have an unconditional right to invoice and receive payment in the future related to those licenses.


At September 30, 2019, and December 31, 2018, total current and long-term accounts receivable, net of allowance for doubtful accounts, was $368.4 million and $314.9 million, respectively. We have recorded unbilled receivables of $126.5 million and $104.2 million at September 30, 2019, and December 31, 2018, respectively. Included in unbilled receivables are retention receivables of $12.9 million and $12.2 million at September 30, 2019, and December 31, 2018, respectively, which become payable upon the completion of the contract or completion of our fieldwork and formal hearings. Unbilled receivables expected to be collected within one year have been included with accounts receivable, current portion in the accompanying condensed consolidated balance sheets. Unbilled receivables and retention receivables expected to be collected past one year have been included with accounts receivable, long-term portion in the accompanying condensed consolidated balance sheets.
We maintain allowances for doubtful accounts, which are provided at the time the revenue is recognized. Since most of our customers are domestic governmental entities, we rarely incur a loss resulting from the inability of a customer to make required payments. Events or changes in circumstances that indicate the carrying amount for the allowances for doubtful accounts may require revision, include, but are not limited to, deterioration of a customer’s financial condition, failure to manage our customer’s expectations regarding the scope of the services to be delivered, and defects or errors in new versions or enhancements of our software products.
The following table summarizes the changes in the allowance for doubtful accounts:accounts (in thousands):

LEASES
The allowance for doubtful accounts reflects our best estimate of probable losses inherent in the accounts receivable balance. We determine the allowanceif an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, other current liabilities, and operating lease liabilities on our consolidated balance sheets. We currently do not have any finance lease arrangements.
Operating lease ROU assets and operating lease liabilities are recognized based on known troubled accounts, historical experience, and other currently available evidence.
In connection with our appraisal services contracts and certain software services contracts, we may perform work prior to when the software and services are billable and/or payable pursuant topresent value of the contract. Unbilled revenue is not billable at the balance sheet date but is recoverablefuture minimum lease payments over the remaining life of the contract through billings made in accordance with contractual agreements. The termination clauses inlease term at commencement date. As most of our contractsleases do not provide foran implicit rate, we use our incremental borrowing rate based on the payment forinformation available at commencement date of the lease in determining the present value of products deliveredfuture payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. Our lease terms may include options to extend or services performed interminate the event of early termination. We have historically recorded such unbilled receivables (costs and estimated profit in excess of billings) in connection with (1) property appraisal services contracts accountedlease when it is reasonably certain that we will exercise that option. Lease expense for using progress-to-completion method of revenue recognition using labor hours as a measure of progress towards completion in which the services are performed in one accounting period but the billing normally occurs subsequently and may span another accounting period; (2) software services contracts accounted for using progress-to-completion method of revenue recognition using labor hours as a measure of progress towards completion in which the services are performed in one accounting period but the billing for the software element of the arrangement may be based upon the specific phase of the implementation; (3) software revenue for which we haveminimum lease payments is recognized revenue at the point in time when the software is made available to the customer but the billing has not yet been submitted to the customer; (4) some of our contracts which provide for an amount to be withheld from a progress billing (generally between 5% and 20% retention) until final and satisfactory project completion is achieved; and (5) in a limited number of cases, extended payment terms, which may be granted to customers with whom we generally have a long-term relationship and favorable collection history.
The opening balance of current and long-term accounts receivable, net of allowance for doubtful accounts, was $226.8 million (as adjusted) as of January 1, 2017.


As of September 30, 2018, and December 31, 2017, total current and long-term accounts receivable, net of allowance for doubtful accounts, was $294.5 million and $258.3 million (as adjusted), respectively. We have recorded unbilled receivables of $86.9 million and $64.6 million (as adjusted) at September 30, 2018, and December 31, 2017, respectively. Included in unbilled receivables are retention receivables of $8.3 million and $7.2 million at September 30, 2018, and December 31, 2017, respectively, which become payable upon the completion of the contract or completion of our fieldwork and formal hearings. Unbilled receivables expected to be collected within one year have been included with accounts receivable, current portion in the accompanying condensed consolidated balance sheets. Unbilled receivables and retention receivables expected to be collected past one year have been included with accounts receivable, long-term portion in the accompanying condensed consolidated balance sheets.
Payment terms and conditions vary by contract type, although, terms generally include a requirement of payment within 30 to 60 days. In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined our contracts generally do not include a significant financing component. The primary purpose of our invoicing terms is to provide customers with simplified and predictable ways of purchasing our products and services, not to receive financing from our customers or to provide customers with financing. Examples include invoicing at the beginning of a subscription term with revenue recognized ratably over the contract period, and multi-year on-premises term licenses that are invoiced annually with revenue recognized upfront.
Deferred Revenue
The majority of deferred revenue consists of deferred maintenance revenue that has been billed based on contractual terms in the underlying arrangement, with the remaining balance consisting of payments received in advance of revenue being earned under software licensing, subscription-based services, software and appraisal services and hardware installation. Refer to Note 13 - Deferred Revenue and Performance Obligations for further information, including deferred revenue by segment and changes in deferred revenue during the period.
Deferred Commissions
Sales commissions earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. Sales commissions for initial contracts are deferred and then amortized on a straight-line basis over a periodthe lease term. Leases with an initial term of benefit that we have determined to be three to seven years. We utilized the 'portfolio approach' practical expedient in ASC 606-10-10-4, which allows entities to apply the guidance to a portfolio of contracts with similar characteristics because the effects12 months or less are not recorded on the financial statements of this approach would not differ materially from applyingbalance sheet; we recognize lease expense for these leases on a straight-line basis over the guidance to individual contracts. Using the 'portfolio approach', we determined the period of benefit by taking into consideration our customer contracts, our technology life-cyclelease term. We have lease agreements with lease and other factors. Sales commissions for renewal contractsnon-lease components, which are generally not paid in connection with the renewal ofaccounted as a contract. In the small number of instances where a commission is paid on a renewal, it is not commensurate with the commission paid on the initial sale and is recognized over the term of renewal, which is generally one year. Amortization expense related to deferred commissions is included in selling, general and administrative expenses in the accompanying condensed consolidated statements of income. Refer to Note 5 - Deferred Commissions for further information.single lease component.
RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

Revenue from Contracts with Customers. In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU No. 2014-09, Revenue from Contracts with Customers. ASU No. 2014-09 supersedes the revenue recognition requirements in Accounting Standards Codification ("ASC") Topic 605, Revenue Recognition ("Topic 605"), and requires the recognition of revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. This model involves a five-step process that includes identifying the contract with the customer, identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations in the contract and recognizing revenue when (or as) the entity satisfies the performance obligations. Topic 606 also includes Subtopic 340-40 Other Assets and Deferred Costs - Contracts with Customers, which requires the deferral of incremental costs of obtaining a contract with a customer. Collectively, we refer to ASU No. 2014-09 and Subtopic 340-40 as the "new standard."

Leases.We adopted Topic 842 using the requirements oftransition method that allows us to initially apply the new standard asguidance at the adoption date of January 1, 2018, utilizing2019, and recognized a cumulative-effect adjustment to the full retrospective methodopening balance of transition. Adoptionretained earnings in the period of adoption. We used the package of practical expedients that allows us to not reassess: (1) lease classification for any expired or existing leases and (2) initial direct costs for any expired or existing leases. We did not elect to use the hindsight application for evaluating the life of the new standard resultedlease arrangement. The impact of adoption is reflected in changesthe financial information herein. For additional details, see Note 10 to our accounting policies for revenue recognition, trade and other receivables, and deferred commissions as detailed below. We applied the new standard using a practical expedient where the consideration allocated to the remaining performance obligations or an explanation of when we expect to recognize that amount as revenue for all reporting periods presented before the date of the initial application is not disclosed.



condensed consolidated financial statements.
The impact of adopting ASU No. 2014-09Topic 842 on our total revenuesconsolidated balance sheet beginning January 1, 2019, included the recognition of ROU assets and lease liabilities for 2017 and 2016 was not material. The impact of adopting the new standard on our retained earnings and deferred commissions is material. The most significant impact of the new standard relates tooperating leases, while our accounting for software license revenue. Specifically, under the new standard, software license fees under perpetual agreements are no longer subject to 100% discount allocations from other performance obligations in the contract. Discounts in arrangements are allocated across all performance obligations increasing license revenues and decreasing revenues allocated to other performance obligations. In addition, in most cases, net license fees (total license fees less any allocated discounts) are recognized at the point in time when control of the software license transfers to the customer versus our legacy policy of recognizing revenue upon delivery and only to the extent billable per the contractual terms. Under the new standard, time-based license fees are no longer recognized over the contractual period of the license and are instead recognized at the point in time when the control of the software license transfers to the customer. Revenues related to our PCS renewals, SaaS offerings and appraisal services remainfinance leases remained substantially unchanged. Due to the complexity of certain contracts, the actual revenue recognition treatment required under the new standard is dependent on contract-specific terms and may vary in some instances from recognition at the time of billing.

Adoption of the new standard requires that incremental costs directly related to obtaining a contract (typically sales commissions) must be recognized as an asset and expensed on a systematic basis that is consistent with the transfer to the customer of the goods and services to which the asset relates, unless that life is less than one year. Prior to adoption of the new standard, we deferred sales commissions and recognized expense over the relevant initial contractual term, which was generally one to two years. Under the new standard, we amortize these costs over a period of benefit that we have determined to be three to seven years.

We adjusted our condensed consolidated financial statements from amounts previously reported duehad no finance leases prior to the adoption of Topic 842 and currently do not have any.

Recent tax legislation. On December 22, 2017, the Tax Cuts and Jobs Act ("Tax Act") was enacted into law. The Tax Act amends the Internal Revenue Code to reduce tax rates and modify policies, credits and deductions for businesses and individuals. For businesses, the Tax Act reduces the U.S. corporate federal income tax rate from a maximum of 35% to a flat 21% rate and transitions from a worldwide tax system to a territorial tax system. The Tax Act also adds many new provisions including changes to bonus depreciation, the deduction for executive compensation and a tax on global intangible low-taxed income (GILTI). The most significant impact of the Tax Act to us is the reduction in the U.S. federal corporate income tax rate. Refer to Note 8 - Income Tax Provision for further information.Topic 842.

Leases. On February 25,In June 2016, the FASB issued its new lease accounting guidance in ASU No. 2016-02, Leases ("Topic 842"2016-13, Financial Instruments - Credit Losses, (“ASU 2016-13”). UnderASU 2016-13 changes the new guidance, lessees will be required to recognize the followingimpairment model for all leases (except for short-term leases) at the commencement date:
A lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis;most financial assets and
A right-of-use asset, which is an asset that represents the lessee’s right certain other instruments, including trade and other receivables, held-to-maturity debt securities and loans, and requires entities to use or control the use of, a specified asset for the lease term.
Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presentednew forward-looking expected loss model that will result in the financial statements.

(5)    Deferred Commissions

Sales commissions earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. Sales commissions for initial contracts are deferred and then amortized commensurate with the recognition of associated revenue over a period of benefit that we have determined to be three to seven years. Deferred commissions were $21.4$27.4 million and $19.3$21.9 million (as adjusted) as of September 30, 2018,2019, and December 31, 2017,2018, respectively. Amortization expense was $4.4 million and $12.3 million for the three and nine months ended September 30, 2019, respectively, and $3.8 million and $10.9 million for the three and nine months ended September 30, 2018, respectively, and $2.6 million and $7.9 million for the three and nine months ended September 30, 2017 (as adjusted), respectively. There were no0 indicators of impairment in relation to the costs capitalized for the periods presented. Deferred commissions have been included with prepaid expenses for the current portion and non-current other assets for the long-term portion in the accompanying condensed consolidated balance sheets. Amortization expense related to deferred commissions is included in selling,Selling, general and administrative expenses in the accompanying condensed consolidated statements of income.

(6)    Other Assets

Cash and cash equivalents consist of cash on deposit with several domestic banks and money market funds.
As of September 30, 2018,2019, we have $95.8$68.2 million in investment grade corporate and municipal bonds with maturity dates ranging through 2022. We intend to hold these bonds to maturity and have classified them as such. We believe cost approximates fair value because of the relatively short duration of these investments. The fair values of these securities are considered Level II as they are based on inputs from quoted prices in markets that are not active or other observable market data. These investments are included in short-term investments and non-current investments and other assets.
We have a $15.0 million investment in convertible preferred stock representing a 20% interest in Record Holdings Pty Limited, a privately held Australian company specializing in digitizing the spoken word in court and legal proceedings. The investment in convertible preferred stock is accounted under the cost method because we do not have the ability to exercise significant influence over the investee and the securities do not have readily determinable fair values. Our investment is carried at cost less any impairment write-downs. Annually, our cost method investments are assessed for impairment. We do not reassess the fair value of cost method investments if there are no identified events or changes in circumstances that may have a significant adverse effect on the fair value of the investments. This investment is included in non-current investments and other assets.

(7)    Revolving Line of Credit


On November 16, 2015,September 30, 2019, we entered into a $300$400 million credit agreement with various lender parties and Wells Fargo Bank, National Association, as Administrative Agent (the “Credit Facility”Agreement”). The Credit FacilityAgreement provides for a revolving credit line up to $300$400 million, including a $10$25 million sublimit for letters of credit. The Credit FacilityAgreement matures on September 30, 2024. The new Credit Agreement replaces Tyler’s existing $300 million secured credit facility, which was scheduled to mature in November 16, 2020. Borrowings under the Credit FacilityAgreement may be used for general corporate purposes, including working capital requirements, acquisitions and share repurchases.

Borrowings under the Credit FacilityAgreement bear interest at a rate of either (1) Wells Fargo Bank’s prime rate (subject to certain higher rate determinations) plus a margin of 0.25%0.125% to 1.00%0.75% or (2) the 30, 60, 90one-, two-, three-, or 180 daysix-month LIBOR rate plus a margin of 1.25%1.125% to 2.00%1.75%. As of September 30, 2018,2019, the interest rates were 5.25% under the Wells Fargo Bank's prime rate and 3.49%approximately 3.14% under athe 30-day LIBOR contract.option. The Credit Facility is secured by substantially all of our assets. The Credit FacilityAgreement requires us to maintain certain financial ratios and other financial conditions and prohibits us from making certain investments, advances, cash dividends or loans, and limits incurrence of additional indebtedness and liens. As of September 30, 2018,2019, we were in compliance with those covenants.

As of September 30, 2018,2019, we had no0 outstanding borrowings. Available borrowing capacityborrowings under the Credit FacilityAgreement, and available borrowing capacity was $300$400.0 million.





(8)    Income Tax Provision

We had an effective income tax rate of 0.4% and 11.0% for the three and nine months ended September 30, 2019, respectively, compared to negative 0.8% and negative 0.1% for the three and nine months ended September 30, 2018, respectively, compared to 12.4% and 12.5% (as adjusted)respectively. The change in the effective tax rate for the three and nine months ended September 30, 2017, respectively. 2019, as compared to the same period in 2018, was principally driven by the fluctuations of the excess tax benefits related to stock incentive awards.
The effective income tax rates for the periods presented were different from the statutory United States federal income tax rate of 21% in 2018 and 35% in 2017 principally due to excess tax benefits related to stock option exercises.incentive awards, state income taxes, non-deductible business expenses, and the tax benefit of research tax credits. The excess tax benefitbenefits related to stock option exercisesincentive awards realized waswere $11.6 million and $18.6 million for the three and nine months ended September 30, 2019, respectively, compared to $9.3 million and $30.0 million for the three and nine months ended September 30, 2018, respectively, compared to $9.0 millionrespectively. Excluding the excess tax benefits, the effective rate was 28.9% and $27.6 million27.6% for the three and nine months ended September 30, 2017, respectively. Excluding the excess tax benefits, the effective rate was2019, compared to 23.3% and 25.8% for the three and nine months ended September 30, 2018, respectively, compared to 32.8% and 35.9% (as adjusted) for the three and nine months ended September 30, 2017, respectively. Other differences from the federal statutory income tax rate include state income taxes, non-deductible business expenses, the tax benefit of research tax credits, provisional amounts associated with the Tax Act recorded in 2018, and in 2017, the tax benefit of the domestic production activities deduction.

The decrease in effective tax rate for the three and nine months ended September 30, 2018, as compared to the same periods in 2017 was due primarily to the reduction of the U.S. corporate tax rate from 35% to 21% as a result of the Tax Act, the increase in excess tax benefit related to stock option exercises and the research tax credit benefit, offset by the elimination of the domestic production activities deduction and the increased limitations on the deduction for executive compensation. In the fourth quarter of 2017, we recorded a $26.0 million (as adjusted under Topic 606) tax benefit due to the remeasurement of deferred tax assets and liabilities at a lower tax rate. As of September 30, 2018, we increased the provisional amounts for the income tax effects of the Tax Act recorded in 2017 to $27.7 million to reflect actual amounts reported in income tax returns filings. We will continue to analyze the estimates and further guidance on the application of the law, and additional revisions may occur throughout the allowable measurement period which will not exceed one year from the enactment of the Tax Act. Overall, the changes due to the Tax Act will favorably affect income tax expense and future U.S. earnings. 
We made tax payments of $6.8$18.1 million and $29.0$6.8 million in the nine months ended September 30, 2018,2019, and 2017,2018, respectively.

The majority of intercompany transactions relate to contracts involving more than one unit and are valued based on the contractual arrangement. Segment operating income for corporate primarily consists of compensation costs for the executive management team and certain accounting and administrative staff and share-based compensation expense for the entire company. Corporate segment operating income also includes revenues and expenses related to a company-wide user conference.

Recurring Revenue
The majority of our revenue is comprised of recurring revenues from maintenance and subscriptions. Virtually all of our on-premises software clients contract with us for maintenance and support, which provides us with a significant source of recurring revenue. We generally provide maintenance and support for our on-premises clients under annual, or in some cases, multi-year contracts. The contract terms for subscription arrangements range from one to 10 years but are typically contracted for initial periods of three to five years, providing a significant source of recurring revenues on an annual basis. Non-recurring revenues are derived for all other revenue categories.
Recurring revenues and non-recurring revenues recognized during the period are as follows:follows (in thousands):

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
CAUTIONARY NOTE CONCERNING FORWARD-LOOKING STATEMENTS
This document contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 that are not historical in nature and typically address future or anticipated events, trends, expectations or beliefs with respect to our financial condition, results of operations or business. Forward-looking statements often contain words such as “believes,” “expects,” “anticipates,” “foresees,” “forecasts,” “estimates,” “plans,” “intends,” “continues,” “may,” “will,” “should,” “projects,” “might,” “could” or other similar words or phrases. Similarly, statements that describe our business strategy, outlook, objectives, plans, intentions or goals also are forward-looking statements. We believe there is a reasonable basis for our forward-looking statements, but they are inherently subject to risks and uncertainties and actual results could differ materially from the expectations and beliefs reflected in the forward-looking statements. We presently consider the following to be among the important factors that could cause actual results to differ materially from our expectations and beliefs: (1) changes in the budgets or regulatory environments of our clients, primarily local and state governments, that could negatively impact information technology spending; (2) our ability to protect client information from security breaches and provide uninterrupted operations of data centers; (3) our ability to achieve growth or operational synergies through the integration of acquired businesses, while avoiding unanticipated costs and disruptions to existing operations; (4) material portions of our business require the Internet infrastructure to be adequately maintained; (5) our ability to achieve our financial forecasts due to various factors, including project delays by our clients, reductions in transaction size, fewer transactions, delays in delivery of new products or releases or a decline in our renewal rates for service agreements; (6) general economic, political and market conditions; (7) technological and market risks associated with the development of new products or services or of new versions of existing or acquired products or services; (8) competition in the industry in which we conduct business and the impact of competition on pricing, client retention and pressure for new products or services; (9) the ability to attract and retain qualified personnel and dealing with the loss or retirement of key members of management or other key personnel; and (10) costs of compliance and any failure to comply with government and stock exchange regulations. A detailed discussion of these factors and other risks that affect our business are described in Item 1A, “Risk Factors.” We expressly disclaim any obligation to publicly update or revise our forward-looking statements.

The declineincrease in software license and royalties revenue for the three months ended September 30, 2018 was primarily due2019, is attributed to an increase in the numberseveral large on-premise sales of new softwareour financial management and schools and planning solutions partially offset by more clients choosing our subscription-based options,subscription based option, rather than purchasing the software under a traditional perpetual software license arrangement. The increasedecline in software licenses and royalties revenue for the nine months ended September 30, 2018,2019, is primarily attributed to additionsa shift in the mix of new software contracts toward more subscription agreements compared to our implementation staff, which increased our capacitythe prior year. Our total new contract value mix for the nine months ended September 30, 2019, was approximately 49% perpetual software license arrangements and approximately 51% subscription-based arrangements compared to deliver backlog.total new contract value mix for the nine months ended September 30, 2018, of approximately 63% perpetual software license arrangements and approximately 37% subscription-based arrangements.

Although the mix of new contracts between subscription-based and perpetual license arrangements may vary from quarter to quarter and year to year, we expect our longer-term software license growth rate to slow as a growing number of clients choose our subscription-based options, rather than purchasing the software under a traditional perpetual software license arrangement. Subscription-based arrangements generally do not result in lower software license revenue in the initial year as compared to perpetual software license arrangements but generate higher overall revenue over the term of the contract. Our new client mix for the nine months ended September 30, 2018, was approximately 43% perpetual software license arrangements and approximately 57% subscription-based arrangements compared to a client mix for the nine months ended September 30, 2017, of approximately 51% perpetual software license arrangements and approximately 49% subscription-based arrangements.

New SaaS clients as well as existing clients who converted to our SaaS model provided the majority of the subscriptions revenue increase. In the three and nine months ending September 30, 2018,2019, respectively, we added 81150 and 329432 new SaaS clients and 3120 and 8960 existing on-premises clients converted to our SaaS model. Since September 30, 2017,2018, we have added 412513 new SaaS clients while 10868 existing on-premises clients converted to our SaaS model. Also, e-filing services contributed approximately $1.4 million and $5.6$5.3 million to the subscriptions revenue increase for the three and nine months ended September 30, 2018,2019, respectively, due to the addition of new e-filing clients, as well as increased volumes as the result of several existing clients mandating e-filing.

In the three and nine months ended September 30, 2018, respectively,2019, our software licenses, royalties and acquired software gross margin decreased 2.8%4.7% and 0.6%7.8%, respectively, compared to the prior year period due to higher amortization expense for acquired software resulting from acquisitions. Excluding the impact of acquisitions amortization expense, our software license, royalties and acquired software gross margin was 71.7% for the both three and nine months ended September 30, 2018, respectively.



Software services, maintenance and subscriptions. Cost of software services, maintenance and subscriptions primarily consists of personnel costs related to installation of our software, conversion of client data, training client personnel and support activities and various other services such as custom client development and ongoing operation of SaaS and e-filing arrangements. The software services, maintenance and subscription gross margin in the three and nine months ended September 30, 2018,2019, both increased 1.4% and 1.7% , respectively, decreased 1.1% and 0.6% from the comparable prior year period. Excluding employees added through acquisitions, our implementation and support staff has grown by 86233 employees since September 30, 2017,2018, as we accelerated hiring to ensure that we are well-positioned to deliver our current backlog and anticipated new business. Costs related to maintenance and various other services such as SaaS and e-filing typically grow at a slower rate than related revenue due to leverage in the utilization of support and maintenance staff and economies of scale. 
Appraisal services. Appraisal services revenue was approximately 2%2.2% of total revenue for both the three and nine months ended September 30, 2018,2019, respectively. The appraisal services gross margin for the three and nine months ended September 30, 2018,2019, decreased 5.0% and increased 1.1%, respectively, increased 1.8% and decreased 0.7% compared to the same period in 2017.2018. During the three months ended September 30, 2018,2019, appraisal services gross margin increaseddecreased due to lower headcount of appraisal staff.staffing increases resulting from new revaluation projects. During the nine months ended September 30, 2018,2019, appraisal services gross margin decreased primarilyincreased due to the completionramp up of certain higher-marginseveral new revaluation projects in 2017 and a lower volume of revenues in the current period to cover relatively fixed costs.during second quarter 2019. The appraisal services business is somewhat cyclical and driven in part by statutory revaluation cycles in various states.
 
For the three and nine months ended September 30, 2018,2019, respectively, our overall gross margin decreased 1.1%increased 0.2% and 0.5%0.3% compared to the prior year period.periods. Our overall gross margin decreaseincreases for the both three and nine months period is mainlyperiods are attributed to additionsa higher revenue mix for subscription revenues compared to our implementationthe prior year periods resulting in an increase in incremental margin related to software services, maintenance and subscriptions. Costs related to maintenance and various other services such as SaaS and e-filing typically grow at a slower rate than related revenue due to leverage in the utilization of support and maintenance staff combined withand economies of scale. The increase in overall margins are partially offset by lower margin revenuesmargins from software licenses, in part due to lower software license revenue and higher amortization expense for acquired software resulting from acquisitions.

Amortization of Customer and Trade NameOther Intangibles
Acquisition intangibles are composed of the excess of the purchase price over the fair value of net tangible assets acquired that is primarily allocated to acquired software and customer and trade name intangibles. The remaining excess purchase price is allocated to goodwill that is not subject to amortization. Amortization of customer and trade name intangibles increased substantially from the comparable prior year periods due to the acquisition of Socrata in April 2018. Amortization expense related to acquired software is included with cost of revenues while amortization expense of customer and trade name intangibles is recorded as operating expense. The increase in amortization of other intangibles is primarily attributed to the acquisition of Socrata, Inc. and MicroPact, which closed during the second quarter of 2018 and first quarter of 2019, respectively.

The decreasechange in effective tax rate for the three and nine months ended September 30, 2018,2019, as compared to the same periodperiods in 20172018, was due primarily toprincipally driven by the reductionfluctuations of the U.S. corporate tax rate from 35% to 21% as a result of the Tax Act, the increase in the excess tax benefitbenefits related to share-based compensation and research tax credit benefit, offset by the elimination of the domestic production activities deduction and the increased limitations on the deduction for executive compensation.stock incentive awards. The effective income tax rates for the three and nine months ended September 30, 20182019 and 2017,2018, respectively, were different from the statutory United States federal income tax rates of 21% and 35%, respectively, principally due to excess tax benefits related to stock option exercises.incentive awards, state income taxes, non-deductible business expenses, and the tax benefit of research tax credits. The excess tax benefitbenefits related to stock option exercisesincentive awards realized waswere $11.6 million and $18.6 million for the three and nine months ended September 30, 2019, respectively, compared to $9.3 million and $30.0 million for the three and nine months ended September 30, 2018, respectively, compared to $9.0 millionrespectively.


Excluding the excess tax benefits, the effective rate was 28.9% and $27.6 million27.6% for the three and nine months ended September 30, 2017, respectively. Excluding the excess tax benefits, the effective rate was2019, compared to 23.3% and 25.8% for the three and nine months ended September 30, 2018, respectively, compared to 32.8% and 35.9% (as adjusted) for the three and nine months ended September 30, 2017, respectively. Other differences from the federal statutory income tax rate include state income taxes, non-deductible business expenses, the tax benefit of research tax credits, provisional amounts associated with the Tax Act recorded in 2018, and in 2017, the tax benefit of the domestic production activities deduction.



FINANCIAL CONDITION AND LIQUIDITY
As of September 30, 2018,2019, we had cash and cash equivalents of $219.5$161.4 million compared to $185.9$134.3 million at December 31, 2017.2018. We also had $95.8$68.2 million invested in investment grade corporate and municipal bonds as of September 30, 2018.2019. These investments mature through 2022, and we intend to hold these investments until maturity. As of September 30, 2018,2019, we believe our cash from operating activities, revolving line of credit, cash on hand and access to the capital markets provides us with sufficient flexibility to meet our long-term financial needs.
The following table sets forth a summary of cash flows for the nine months ended September 30:

Net cash provided by operating activities continues to be our primary source of funds to finance operating needs and capital expenditures. Other potential capital resources include cash on hand, public and private issuances of debt or equity securities, and bank borrowings. It is possible that our ability to access the capital and credit markets in the future may be limited by economic conditions or other factors. We believe that cash provided by operating activities, cash on hand and available credit are sufficient to fund our working capital requirements, capital expenditures, income tax obligations, and share repurchases for at least the next twelve months.
 
For the nine months ended September 30, 2018,2019, operating activities provided cash of $179.4$178.5 million. Operating activities that provided cash were primarily comprised of net income of $115.9$99.7 million, non-cash depreciation and amortization charges of $45.6$56.5 million, and non-cash share-based compensation expense of $38.0$44.4 million and non-cash decrease in operating lease right-of-use assets of $4.0 million. Working capital, excluding cash, increased approximately $20.2$26.1 million mainly due to higher accounts receivable because of an increase in unbilled receivables attributed to revenues recognized prior to billings and annual subscription billings, higher deferred commissions and the timing of payments related to bonuses, timing of tax payments and the deferred taxes associated with stock option activity during the period. These increases were offset by an increase in deferred revenue attributed to growthduring the period. In general, changes in deferred revenue are cyclical and primarily driven by the timing of our installed software maintenance customer baserenewal billings and growthsubscription billings. Our maintenance renewal dates occur throughout the year, but our largest renewal billing cycles occur in subscription-based arrangements.the second and fourth quarters. In addition, subscription renewals are billed throughout the year.
Our days sales outstanding (“DSO”) was 114 days at September 30, 2019, compared to 111 days at December 31, 2018 and 107 days at September 30, 2018, compared to 102 days (as adjusted) at December 31, 2017 and 94 days (as adjusted) at September 30, 2017.2018. The increase in our DSO compared to December 31, 2018, is mainly due to an increase in unbilled receivablesprimarily attributed to the increase in software license revenue for which we have recognized revenue at the point in time when the software is made available to the customer but the billing has not yet been submitted to the customer, as well as an increase in software services contracts accounted for using progress-to-completion method of revenue recognition in which the services are performed in one accounting period but the billing normally occurs subsequently in another accounting period. Furthermore, our maintenance billing cycle typically peakspeaking at its highest level in June and second highest level in December of each year and is followed by collections in the subsequent quarter. DSO is calculated based on quarter-end accounts receivable divided by the quotient of annualized quarterly revenues divided by 360 days. The increase in DSO compared to September 30, 2018, is mainly due to an increase in unbilled receivables attributable to an increase in software services contracts accounted for using progress-to-completion method of revenue recognition in which the services are performed in one accounting period, but the billing normally occurs subsequently in another accounting period. 
Investing activities used cash of $203.2 million in the nine months ending September 30, 2019. On February 28, 2019, we acquired all of the capital stock of MicroPact.

The repurchase program, which was approved by our board of directors, was originally announced in October 2002 and was amended at various times from 2003 through 2016.2019. As of September 30, 2019, we had authorization from our board of directors to repurchase up to 2.6 million additional shares of Tyler common stock. Our share repurchase program allows us to repurchase shares at our discretion. Market conditions influence the timing of the buybacks and the number of shares repurchased, as well as the volume of employee stock option exercises. Share repurchases are generally funded using our existing cash balances and borrowings under our credit facility and may occur through open market purchases and transactions structured through investment banking institutions, privately negotiated transactions and/or other mechanisms. There is no expiration date specified for the authorization, and we intend to repurchase stock under the plan from time to time.

Excluding acquisitions, weWe anticipate that 20182019 capital spending will be between $23$45 million and $26$47 million, including approximately $2$20 million related to real estate.estate and approximately $6 million of capitalized software development. We expect the majority of the other capital spending will consist of computer equipment and software for infrastructure replacements and expansion. We currently do not expect to capitalize significant amounts related to software development in 2018, but the actual amount and timing of those costs, and whether they are capitalized or expensed may result in additional capitalized software development. Capital spending is expected to be funded from existing cash balances and cash flows from operationsoperations.

On October 30, 2019, we acquired certain assets of Courthouse Technologies, Ltd, an industry-leading provider of jury management systems that offers fully integrated, end-to-end software-as-a-service (SaaS) solution to manage all facets of juror management, from source list generation to juror processing and borrowings under our revolving line of credit.payment. The total purchase price was approximately $19 million in cash, subject to certain post-closing adjustments.

From time to time we engage in discussions with potential acquisition candidates. In order to consummate anypursue such opportunities, which could require significant commitments of capital, we may be required to incur debt or to issue additional potentially dilutive securities in the future. No assurance can be given as to our future acquisitionsacquisition opportunities and how such acquisitions mayopportunities will be financed.

We lease office facilities, as well as transportation and other equipment used in our operations under non-cancelable operating lease agreements expiring at various dates through 2027.

Part II. OTHER INFORMATION


ITEM 1. Legal Proceedings
Other than routine litigation incidental to our business, there are no material legal proceedings pending to which we are party or to which any of our properties are subject.


ITEM 1A. Risk Factors
In addition to the other information set forth in this report, one should carefully consider the discussion of various risks and uncertainties contained in Part I, “Item 1A. Risk Factors” in our 20172018 Annual Report on Form 10-K. We believe those risk factors are the most relevant to our business and could cause our results to differ materially from the forward-looking statements made by us. Please note, however, that those are not the only risk factors facing us. Additional risks that we do not consider material, or of which we are not currently aware, may also have an adverse impact on us. Our business, financial condition and results of operations could be seriously harmed if any of these risks or uncertainties actually occurs or materializes. In that event, the market price for our common stock could decline, and our shareholders may lose all or part of their investment. During the three months ended September 30, 2018,2019, there were no material changes in the information regarding risk factors contained in our Annual Report on Form 10-K for the year ended December 31, 2017.2018.
