SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
Certain statements in this Quarterly Report on Form 10-Q are “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, and are subject to the safe harbor created thereby. All statements contained in this Quarterly Report on Form 10-Q other than statements of historical facts, including statements regarding our future results of operations and financial position, our business strategy and plans and our objectives for future operations, are forward-looking statements. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect” and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives, and financial needs. These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including those described in “Item 1A. Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2018, in “Item 1A. Risk Factors” in Part II of this Quarterly Report on Form 10-Q and in any subsequent filing we make with the SEC, as well as in any documents incorporated by reference that describe risks and factors that could cause results to differ materially from those projected in these forward-looking statements.
Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the future events and trends discussed in this Quarterly Report on Form 10-Q may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.
Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance, achievements or events and circumstances reflected in the forward-looking statements will occur. We are under no duty to update any of these forward-looking statements after completion of this Quarterly Report on Form 10-Q to conform these statements to actual results or revised expectations.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
1. Organization and Significant Accounting Policies
Organization
Workiva Inc., a Delaware corporation, and its wholly-owned subsidiaries (the “Company” or “we” or “us”) is a leading provider of cloud-based solutions for connected data, reporting and compliance. Our platform, Wdesk, is used by thousands of public and private companies, government agencies and higher-education institutions. Wdesk offers controlled collaboration, data linking, data integrations, granular permissions, process management and a full audit trail. We sell to customers in the areas of: finance and accounting; risk and controls; regulatory reporting; financial close, management and performance reporting; and statutory and corporate tax reporting. Our operational headquarters are located in Ames, Iowa, with additional offices located in the United States, Europe, the Asia-Pacific region and Canada.
We updated our accounting policies on the use of estimates, impairment of long-lived assets and leases as a result of our adopting Financial Accounting Standards Board (FASB) guidance issued in accounting standards codification (ASC) 842, Leases, under the Accounting Standards Update (ASU) 2016-02 (collectively the new lease standard). Otherwise, 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 condensed consolidated financial statements and related notes.
Basis of Presentation and Principles of Consolidation
The financial information presented in the accompanying unaudited condensed consolidated financial statements has been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and in accordance with rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, the financial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The condensed consolidated balance sheet data as of December 31, 2018 was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, consisting primarily of normal recurring accruals, necessary for a fair presentation of our financial position and results of operations. The operating results for the three and nine months ended March 31,September 30, 2019 are not necessarily indicative of the results expected for the full year ending December 31, 2019.
Seasonality has affected our revenue, expenses and cash flows from operations. Revenue from professional services has been higher in the first quarter as many of our customers file their Form 10-K in the first calendar quarter. Sales and marketing expense has been higher in the third quarter due to our annual user conference in September. In addition, the timing of the payments of cash bonuses to employees during the first and fourth calendar quarters may result in some seasonality in operating cash flow. The condensed consolidated financial information should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in this report and the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018 filed with the SEC on February 20, 2019.
The unaudited condensed consolidated financial statements include the accounts of Workiva Inc. and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Additionally, certain prior period amounts have been reclassified for consistency with the current year presentation. The reclassification of the prior period amounts were not material to the previously reported consolidated financial statements.

Table of Contents
Use of Estimates
The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We base our estimates on historical experience and various other assumptions believed to be reasonable. These estimates include, but are not limited to, the allowance for doubtful accounts, the determination of the relative selling prices of our services, the measurement of material rights, health insurance claims incurred but not yet reported, valuation of available-for-sale marketable securities, useful lives of deferred contract costs, intangible assets and property and equipment, income taxes, discount rates used in the valuation of right-of-use assets and lease liabilities, the fair value of the liability and equity components of the convertible senior notes, and certain assumptions used in the valuation of equity awards. While these estimates are based on our best knowledge of current events and actions that may affect us in the future, actual results may differ materially from these estimates.
Impairment of Long-Lived Assets
Long-lived assets, such as property, equipment, right-of-use assets and software and intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. If circumstances require that a long-lived asset or asset group be tested for possible impairment, we first compare the undiscounted cash flows expected to be generated by that long-lived asset or asset group to its carrying amount. If the carrying amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying amount exceeds its fair value.
Leases
We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU"(“ROU”) assets, other current liabilities, and operating lease liabilities on our condensed consolidated balance sheets. We currently have no finance leases.
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 operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. Our variable lease payments consist of non-lease services related to the lease. Variable lease payments are excluded from the ROU assets and lease liabilities and are recognized in the period in which the obligation for those payments is incurred. As our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives incurred. 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 minimum lease payments is recognized on a straight-line basis over the lease term.
We have lease agreements with lease and non-lease components. We have elected to account for these lease and non-lease components as a single lease component. We are also electing not to apply the recognition requirements to short-term leases of 12 months or less and instead will recognize lease payments as expense on a straight-line basis over the lease term.

Recently Adopted Accounting Pronouncements
In February 2016, the Financial Accounting Standards Board ("FASB"(“FASB”) issued guidance codified in ASC 842, Leases, which supersedes the guidance in former ASC 840, Leases, to increase transparency and comparability among organizations by requiring recognition of right-of-use assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements (with the exception of short-term leases).
In July 2018, the FASB issued an update (ASU 2018-11) to the existing transition guidance that allows entities to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Effective January 1, 2019, we adopted ASC 842 using this new transition guidance. The comparative information has not been restated and continues to be reported under the accounting standard in effect for those periods.
We have elected to use the package of practical expedients, which allows us to not (1) reassess whether any expired or existing contracts are considered or contain leases; (2) reassess the lease classification for any expired or existing leases; and (3) reassess the initial direct costs for any existing leases. We did not elect the hindsight practical expedient, which permits entities to use hindsight in determining the lease term and assessing impairment.
Adoption of the new standard had a material impact on our condensed consolidated balance sheets. The most significant impacts related to the recognition of right-of-use assets and lease liabilities for operating leases. The adoption of ASC 842 had no impact on our condensed consolidated statements of operations or total cash flows from operations.
The cumulative effect of the changes made to our consolidated January 1, 2019 balance sheet for the adoption of ASC 842 were as follows (in thousands):

The update will become effective for interim and annual periods beginning after December 15, 2019 and may be adopted either retrospectively or prospectively. Early adoption is permitted. We adopted this standard prospectively effective April 1, 2019. The adoption of this new guidance did not have a material impact on our consolidated financial statements.

New Accounting Pronouncements Not Yet Adopted
In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which amends the current accounting guidance and requires the measurement of all expected losses based on historical experience, current conditions and reasonable and supportable forecasts. For trade receivables, loans, and other financial instruments, we will be required to use a forward-looking expected loss model that reflects probable losses rather than the incurred loss model for recognizing credit losses. The standard will become effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted. Application of the amendments is through a cumulative-effect adjustment to retained earnings as of the effective date. We plan to adopt this standard on the effective date and are currently evaluating the impact of this new standard on our consolidated financial statements.

4. Fair Value Measurements
We determine the fair values of our financial instruments based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value assumes that the transaction to sell the asset or transfer the liability occurs in the principal or most advantageous market for the asset or liability and establishes that the fair value of an asset or liability shall be determined based on the assumptions that market participants would use in pricing the asset or liability. The classification of a financial asset or liability within the hierarchy is based upon the lowest level input that is significant to the fair value measurement. The fair value hierarchy prioritizes the inputs into three levels that may be used to measure fair value:
Level 1 - Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2 - Inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.
Level 3 - Inputs are unobservable inputs based on our assumptions.

Table of Contents
Financial Assets
Cash equivalents primarily consist of AAA-rated money market funds with overnight liquidity and no stated maturities. We classified cash equivalents as Level 1 due to the short-term nature of these instruments and measured the fair value based on quoted prices in active markets for identical assets.
When available, our marketable securities are valued using quoted prices for identical instruments in active markets. If we are unable to value our marketable securities using quoted prices for identical instruments in active markets, we value our investments using broker reports that utilize quoted market prices for comparable instruments. We validate, on a sample basis, the derived prices provided by the brokers by comparing their assessment of the fair values of our investments against the fair values of the portfolio balances of another third-party professional pricing service. As of March 31,September 30, 2019, all of our marketable securities were valued using quoted prices for comparable instruments in active markets and are classified as Level 2.
Based on our valuation of our money market funds and marketable securities, we concluded that they are classified in either Level 1 or Level 2, and we have no financial assets measured using Level 3 inputs. The following table presents information about our assets that are measured at fair value on a recurring basis using the above input categories (in thousands):

Convertible Senior Notes
As of September 30, 2019, the fair value of our convertible senior notes was $314.2 million. The fair value was determined based on the quoted price of the convertible senior notes in an over-the-counter market on the last trading day of the reporting period and has been classified as Level 2 in the fair value hierarchy. See Note 6 to the condensed consolidated financial statements for more information.

5. Leases
Operating Leases
We lease certain office and residential space under non-cancelable operating leases with various lease terms through June 2043. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. Certain office leases include one1 or more options to renew, with renewal terms that can extend the lease term from 3 to 5 years. The exercise of lease renewal options is at our sole discretion and is generally excluded from the lease term at lease inception. Our leases generally require us to pay a proportionate share of real estate taxes, insurance, common area maintenance, and other operating costs in addition to a base or fixed rent.

6. Debt
Other Long-Term Debt
In August 2014, we entered into a credit facility with Silicon Valley Bank, which provided us with a revolving line of credit. Under the agreement, we could borrow up to $15.0 million with interest accrued at the bank's prime lending rate. In August 2019,we terminated our credit facility with Silicon Valley Bank. No amounts were outstanding at the time of termination.
Convertible Senior Notes
In August 2019, we issued $345.0 million aggregate principal amount of 1.125% convertible senior notes due 2026 in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended, including the exercise in full by the initial purchasers of their option to purchase an additional $45.0 million principal amount (the “Notes”). The Notes were issued pursuant to an indenture and are senior, unsecured obligations of the Company. The Notes bear interest at a fixed rate of 1.125% per annum, payable semi-annually in arrears on February 15 and August 15 of each year, commencing on February 15, 2020. Proceeds from the issuance of the Notes totaled $335.9 million, net of initial purchaser discounts and issuance costs.
The initial conversion rate is 12.4756 shares of our common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $80.16 per share, subject to adjustment upon the occurrence of specified events. The Notes will be convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding May 15, 2026 only under the following circumstances:
during any calendar quarter commencing after the calendar quarter ending on September 30, 2019 (and only during such calendar quarter), if the last reported sale price of our Class A common stock, par value $0.001 per share (which we refer to in this offering memorandum as our “Class A common stock”), for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;
16

Table of Contents
during the 5 consecutive business day period immediately following any 10 consecutive trading day period (the “measurement period”) in which the trading price (as defined below) per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our Class A common stock and the conversion rate on each such trading day;
if we call any or all of the Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or
upon the occurrence of certain specified corporate events as set forth in the indenture.
On or after May 15, 2026 until the close of business on the business day immediately preceding the maturity date, holders may convert their Notes at any time, regardless of the foregoing circumstances.
Upon conversion, we will pay or deliver, as the case may be, cash, shares of our Class A common stock or a combination of cash and shares of our Class A common stock, at our election, in the manner and subject to the terms and conditions provided in the indenture. It is our current intent to settle conversions through a combination settlement of cash and shares of our Class A common stock with a specified dollar amount per $1,000 principal amount of Notes of $1,000.
If we undergo a fundamental change (as defined in the indenture), holders may require us to repurchase for cash all or any portion of their Notes at a fundamental change repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. In addition, following certain corporate events that occur prior to the maturity date or if we deliver a notice of redemption, we will increase, in certain circumstances, the conversion rate for a holder who elects to convert its Notes in connection with such corporate event or notice of redemption, as the case may be. During the three months ended September 30, 2019, the conditions allowing holders of the Notes to convert were not met. The Notes were therefore not convertible during the three months ended September 30, 2019 and are classified as long-term debt on our condensed consolidated balance sheets.
We may not redeem the Notes prior to August 21, 2023. We may redeem for cash all or any portion of the Notes, at our option, on or after August 21, 2023 if the last reported sale price of our Class A common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which we provide notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.
In accounting for the issuance of the Notes, we separated the Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of similar debt instruments that do not have an associated convertible feature. The carrying amount of the equity component, representing the conversion option, was determined by deducting the fair value of the liability components from the par value of the Notes. The difference represents the debt discount that is amortized to interest expense at an effective interest rate of 4.3% over the term of the Notes. The carrying amount of the equity component was $60.1 million and is recorded in additional paid-in-capital. The equity component is not remeasured as long as it continues to meet the conditions for equity classification.
In accounting for the issuance costs related to the Notes, we allocated the total amount incurred to the liability and equity components of the Notes based on the proportion of the proceeds allocated to the debt and equity components. Issuance costs attributable to the liability component were $7.5 million. The issuance costs allocated to the liability component are amortized to interest expense under the effective

interest rate method over the contractual term of the Notes. Issuance costs attributable to the equity component of the Notes were $1.6 million and are netted against the equity components representing the conversion option in additional paid-in capital.

7. Commitments and Contingencies
Other Purchase Commitments
During 2019, we entered into certain non-cancelable agreements with third-party providers for our use of cloud services in the ordinary course of business. Under these agreements, we are committed to purchase $18,000 in fiscal year 2019, $1.2 million in fiscal year 2020, $2.3 million in fiscal year 2021, and $1.2 million in fiscal year 2022.
Litigation
From time to time we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We evaluate the development of legal matters on a regular basis and accrue a liability when we believe a loss is probable and the amount can be reasonably estimated. Although the results of litigation and claims cannot be predicted with certainty, we currently believe that the final outcome of any currently pending legal proceedings to which we are a party will not have a material adverse effect on our business, operating results, financial condition or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Employee Stock Purchase Plan
The fair value of each share issued under the ESPP is estimated on the date of grant using the Black-Scholes option-pricing model. Expected volatility is based on the historical volatility of our common stock. The expected term represents the period of time the ESPP purchase rights are expected to be outstanding. The expected term for the ESPP purchase rights approximates the offering period. The risk-free interest rate is based on yields on U.S. Treasury STRIPS (Separate Trading of Registered Interest and Principal of Securities) with a maturity similar to the estimated expected term of the ESPP purchase rights.
The fair value of our ESPP purchase rights was estimated assuming no expected dividends and the following weighted-average assumptions:

9.10. Net Loss Per Share
Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including ourconvertible senior notes, outstanding stock options, stock related to unvested restricted stock units, and common stock issuable pursuant to the ESPP to the extent dilutive. Basic and diluted net loss per share was the same for each period presented, as the inclusion of all potential common shares outstanding would have been anti-dilutive.
The net loss per share is allocated based on the participation rights of the Class A and Class B common shares as if the loss for the year has been distributed. As the liquidation and dividend rights are identical, the net loss is allocated on a proportionate basis.
A reconciliation of the denominator used in the calculation of basic and diluted loss per share is as follows (in thousands, except share and per share data):

Wdata also enables a broader set of business users to explore complex data at scale and better manage data transformations in the office of the CFO.
AlthoughWe market our customers employsolutions under six broad categories: SEC Reporting, Management Reporting, Integrated Risk, Capital Markets, Global Statutory Reporting, and Regulated Reporting. Within those categories, Workiva solutions for hundreds of different use cases, we currently focus our salesoffers the following solutions: SEC Reporting, SEDAR Reporting, Financial Reporting, Connected Financials, Management Reporting, Audit Management, Controls Management, Enterprise Risk Management, Policies and marketing resources in five areas: financeProcedures, Capital Markets, Prospectus Fund, Shareholder Reports, Insurance Statutory Reporting, Insurance Prospectus, CAFR/AFR, Stress Testing, Living Will, Tax Reporting, CASS Compliance, Global Statutory Reporting, and accounting; risk and controls; regulatory reporting; financial close, management and performance reporting; and statutory and corporate tax reporting.IFRS 17.
We operate our business on a Software-as-a-Service (SaaS) model. Customers enter into quarterly, annual andor multi-year subscription contracts to gain access to Wdesk. Our subscription fee includes the use of our software and technical support. Prior to the third quarter of 2018, our subscription pricing was based primarily on the number of corporate entities, number of users, level of customer support and length of contract. Thereafter, we began converting existing customer orders to, and signing new orders primarily based on, a solution-based licensing model. Under this new model, operating metrics related to a customer's expected use of each solution determine the price. The solution-based model has a higher contract value than the seat-based model because it typically offers customers unlimited seats per solution and a reduced administrative workload. We expect a substantial majority of our subscription revenue will

be priced on the solution-based licensing model by mid-2020.year-end 2019. We charge customers additional fees primarily for document setup and XBRL tagging services.

We generate sales primarily through our direct sales force and, to a lesser extent, our customer success and professional services teams. In addition, we augment our direct sales channel with partnerships. Our advisory and service partners offer a wider range of domain and functional expertise that broadens the capabilities of Wdesk, bringing scale and support to customers and prospects. Our technology partners enable more data and process integrations to help customers connect critical transactional systems directly to Wdesk, which becomes a central repository of trusted data, with powerful linking, auditability and control features.
Our integrated platform, subscription-based model and exceptional customer support have contributed to a low rate of customer turnover while achieving strong revenue growth. Our subscription and support revenue retention rate was 95.7%94.5% (excluding add-on seats) for the twelve months ended March 31,September 30, 2019.
We continue to invest in the development of our solutions, infrastructure and sales and marketing to drive long-term growth. Our full-time employee headcount expanded to 1,3571,512 at March 31,September 30, 2019 from 1,3131,293 at March 31,September 30, 2018, an increase of 3.4%16.9%.
We have achieved significant revenue growth in recent periods. Our revenue grew to $70.0$74.2 million and $217.6 million during the three and nine months ended March 31,September 30, 2019, respectively, from $59.9$60.9 million and $179.9 million during the three and nine months ended March 31,September 30, 2018, an increase of 16.8%.respectively. We incurred net losses of $7.5$16.1 million and $9.6$31.8 million during the three and nine months ended March 31,September 30, 2019, respectively, compared to $11.0 million and March 31,$42.4 million during the three and nine months ended September 30, 2018, respectively.
Converting existing customer orders to a solution-based licensing model has contributed to the acceleration of growth in our subscription revenue year-to-date, and we expect it to continue to do so through the remainder of 2019. This conversion has also contributed to the improvement in our subscription and support revenue retention rate including add-ons for the same periods. We expect the benefit of this contribution to wane beginning in the last quarter of 2019. Accordingly, we will need to find new sources of revenue to sustain our growth rate beyond 2019. To maintain our revenue growth for the longer term, we have been accelerating our investments in talent, processes and technology, particularly for expansion in EMEA, integrated risk, statutory reporting and Wdata. If these investments do not meet our expectations, we may be unable to sustain our revenue growth rate. We expect these investments to increase operating losses in absolute terms and as a percentage of revenue at least through the fourth quarter of 2019, ahead of any incremental revenue contribution they may generate after 2019.
Key Factors Affecting Our Performance
Generate Growth From Existing Customers. Wdesk can exhibit a powerful network effect within an enterprise, meaning that the usefulness of our platform attracts additional users and more data. Since solution-based licensing offers our customers an unlimited number of seats for each solution purchased, we expect customers to add more seats in Wdesk over time. As more employees in an enterprise use Wdesk, additional opportunities for collaboration and automation drive demand among their colleagues for additional solutions. Furthermore, converting customer contractsorders to solution-based licensing typically generates a one-time increase in contract value for each solution.
Pursue New Customers. Our first software solution enabled customers to streamline and automate their SEC regulatory filing process. In 2013, we began expanding into additionaladjacent markets that were facedchallenged with managing large, complex processes with many contributors and disparate sets of business data. We currently sell to new customers in the areas of finance and accounting; risk and controls; regulatory

reporting; financial close, management and performance reporting; and statutory and corporate tax reporting. We intend to continue to build our sales and marketing organization and leverage our brand equity to attract new customers.
Offer More Solutions. We intend to introduce new solutions to continue to meet growing demand for our Wdesk platform. Our close and trusted relationships with our customers are a source for new use cases, features and solutions. We have a disciplined process for tracking, developing and releasing new solutions that are designed to have immediate, broad applicability; a strong value proposition; and a high return on investment for both Workiva and our customers. Our advance planning team assesses customer needs, conducts industry-based research and defines new markets. This vetting process involves our sales, product marketing, customer success, professional services, research and development, finance and senior management teams.

Expand Across Enterprises. Our success in delivering multiple solutions has created demand from customers for a broader-based, enterprise-wide Wdesk platform. In response, we have been improving our technology and realigning sales and marketing to capitalize on our growing enterprise-wide opportunities. We believe this expansion will add seats and revenue and continue to support our high revenue retention rates. However, we expect that enterprise-wide deals will be larger and more complex, which tend to lengthen the sales cycle.
Add Partners. We continue to addexpand our relationships with partners, including consulting and advisory firms, technology partners, and implementation partners. Our global partners, including global strategic consulting and advisory firms, identify opportunities for our platform to help companies transform financial reporting and integrated risk processes. We also partner with regional accounting, consulting and implementation partners. These highly skilled regional partners offer a broader rangeprovide subject-matter expertise in the implementation of services that leveragespecific solutions and extend our direct sales force by referring opportunities to us. Technology partners expand the capabilitiesecosystem of Wdesk. Our technology partnersour connected reporting and compliance platform and enable data connections and process integrations to further streamlinetransform critical business functions, as we capitalize on growing demand for Wdesk to address broader-based, enterprise-wide opportunities. We believe that our partner ecosystem extends our global reach, accelerates the usage and adoption of our platform, and enables more efficient delivery of professional services.
Investment in growth. We plan to continue to invest in the development of our Wdesk platform to enhance our current offerings and build new features. In addition, we expect to continue to invest in our sales, marketing, professional services and customer success organizations to drive additional revenue and support the needs of our growing customer base and to take advantage of opportunities that we have identified in EMEA, as well as use cases for integrated risk, statutory reporting audit management and other use cases.Wdata.
Seasonality. Our revenue from professional services has some degree of seasonality. Many of our customers employ our professional services just before they file their Form 10-K, often in the first calendar quarter. Our sales and marketing expense also has some degree of seasonality. Sales and marketing expense is generally higher in the third quarter since we hold our annual user conference in September. In addition, the timing of the payments of cash bonuses to employees during the first and fourth calendar quarters may result in some seasonality in operating cash flow.

Total customers. We believe total number of customers is a key indicator of our financial success and future revenue potential. We define a customer as an entity with an active subscription contract as of the measurement date. Our customer is typically a parent company or, in a few cases, a significant subsidiary that works with us directly. Companies with publicly listed securities account for a substantial majority of our customers.
Subscription and support revenue retention rate. We calculate our subscription and support revenue retention rate based on all customers that were active at the end of the same calendar quarter of the prior year (“base customers”). We begin by annualizing the subscription and support revenue recorded in the same calendar quarter of the prior year for those base customers who are still active at the end of the current quarter. We divide the result by the annualized subscription and support revenue in the same quarter of the prior year for all base customers.
Our subscription and support revenue retention rate was 95.7%94.5% as of March 31,September 30, 2019, unchangeddown slightly compared to the rate as of March 31,September 30, 2018. We believe that our success in maintaining a high rate of revenue retention is attributable primarily to our robust technology platform and strong customer service.
Subscription and support revenue retention rate including add-ons. Add-on revenue includes the change in both solutions and seats purchased and pricing for existing customers. We calculate our subscription and support revenue retention rate including add-ons by annualizing the subscription and support revenue recorded in the current quarter for our base customers that were active at the end of the current quarter. We divide the result by the annualized subscription and support revenue in the same quarter of the prior year for all base customers.

In the first quarter of 2019, we began calculating revenue retention rates using quarterly ASC 606 revenue instead of our prior method using monthly ASC 605 revenue. We expect quarterly measurements will be less variable than the single month measurements we previously reported.
Annual contract value. Our annual contract value (“ACV”) for each customer is calculated by annualizing the subscription and support revenue recognized during each quarter. We believe the increase in the number of larger contracts shows our progress in expanding our customers' adoption of Wdesk.
Components of Results of Operations
Revenue
We generate revenue through the sale of subscriptions to our cloud-based software and the delivery of professional services. We serve a wide range of customers in many industries, and our revenue is not concentrated with any single customer or small group of customers. For the threenine months ended March 31,September 30, 2019 and 2018, no single customer represented more than 1% of our revenue, and our largest 10 customers accounted for less than 5% of our revenue in the aggregate.
We generate sales directly through our sales force and partners. We also identify some sales opportunities with existing customers through our customer success and professional services teams.
Our customer contracts typically range in length from threetwelve to 36 months. We typically invoice our customers for subscription fees in advance, with payment due at the start of the subscription term. From time to time, we offer limited incentives for customers to enter into contract terms of more than one year, typically for terms of two or three years. Our arrangements do not contain general rights of return.

Table of Contents
Subscription and Support Revenue. We recognize subscription and support revenue on a ratable basis over the contract term beginning on the date that our service is made available to the customer. Amounts that are invoiced are initially recorded as deferred revenue.
Professional Services Revenue. We believe our professional services facilitate the sale of our subscription service to certain customers. To date, most of our professional services have consisted of document set up, XBRL tagging, and consulting with our customers on business processes and best practices for using Wdesk. Our professional services are not required for customers to utilize our solution. We recognize revenue for document set ups when the service is complete and control has transferred to the customer. Revenues from XBRL tagging and consulting services are recognized as the services are performed.
Cost of Revenue
Cost of revenue consists primarily of personnel and related costs directly associated with our professional services, customer success teams and training personnel, including salaries, benefits, bonuses, and stock-based compensation; the costs of contracted third-party vendors; the costs of server usage by our customers; information technology costs; and facility costs. Costs of server usage are comprised primarily of fees paid to Google Cloud Platform and Amazon Web Services.

Sales and Marketing Expenses
Sales and marketing expenses consist primarily of personnel and related costs, including salaries, benefits, bonuses, commissions, travel, and stock-based compensation. Other costs included in this expense are marketing and promotional events, our annual user conference, online marketing, product marketing, information technology costs, and facility costs. Sales commissions paid where the amortization period is one year or less are expensed as incurred. All other sales commissions are considered incremental costs of obtaining a contract with a customer and are deferred and amortized on a straight-line basis over a period of benefit that we have determined to be three years.
Research and Development Expenses
Research and development expenses consist primarily of personnel and related costs, including salaries, benefits, bonuses, and stock-based compensation; costs of server usage by our developers; information technology costs; and facility costs.
General and Administrative Expenses
General and administrative expenses consist primarily of personnel and related costs for our executive, finance and accounting, legal, human resources, and administrative personnel, including salaries, benefits, bonuses, and stock-based compensation; legal, accounting, and other professional service fees; other corporate expenses; information technology costs; and facility costs.

General and administrative expense as a percentage of revenue improved to 14.8%16.2% in the latest quarter from 19.6%19.5% the same quarter last year due primarily to a reduction of expenses for executive compensation. We expect a higher level of executive compensation expense beginning in the fourth quarter as a result of hiring a chief operating officer and associated staff.
General and administrative expenses decreased $11.7 million during the nine months ended September 30, 2019 compared to the same period a year ago.

In August 2014, we entered into a credit facility with Silicon Valley Bank, which provided us with a revolving line of credit. Under the agreement, we could borrow up to $15.0 million with interest accrued at the bank's prime lending rate. In August 2019, we terminated the credit facility with Silicon Valley Bank. Borrowing capacity is equal to the most recent month’s subscription and support revenue multiplied by a percentage that adjusts based on the prior quarter’s customer retention rate. The credit facility can be used to fund working capital and general business requirements. The credit facility is secured by all of our assets and has first priority over our other debt obligations and requires us to maintain certain financial covenants, including the maintenance of at least $5.0 million of cash on hand or unused borrowing capacity. The credit facility contains certain restrictive covenants that limit our ability to transfer or dispose of assets, merge with other companies or consummate certain changes of control, acquire other companies, pay dividends, incur additional indebtedness and liens, effect changes in management and enter into new businesses. The credit facility has a variable interest rate equal to the bank’s prime lending rate with interest payable monthly and the principal balance due at maturity. The credit facility matures in August 2020.

Off-Balance Sheet Arrangements
During all periods presented, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As a result, we are not exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in those types of relationships.
Critical Accounting Policies and Estimates
Our condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States. U.S. GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses, income taxes and related disclosures. On an ongoing basis, we evaluate our estimates and assumptions. Our actual results may differ from these estimates under different assumptions or conditions.
During the threenine months ended March 31,September 30, 2019, there were no significant changes to our critical accounting policies and estimates as described in the financial statements contained in the Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC on February 20, 2019.

Item 3. Quantitative and Qualitative Disclosures about Market Risk 
For quantitative and qualitative disclosures about market risk, see “Item 7A., Quantitative and Qualitative Disclosures About Market Risk” of our Annual Report on Form 10-K for the year ended December 31, 2018. OurOther than the items described below, our exposures to market risk have not changed materially since December 31, 2018.
Interest Rate Sensitivity
We had cash, cash equivalents and marketable securities totaling $484.8 million as of September 30, 2019. The cash, cash equivalents and marketable securities are held for working capital purposes, including the acquisition of, or investment in, complementary products, technologies, assets, solutions, or businesses. Our investments are made primarily for capital preservation purposes. We do not enter into investments for trading or speculative purposes.
Our cash and cash equivalents consist primarily of cash and money market funds. Our exposure to market risk for changes in interest rates is limited because our cash and cash equivalents have a short-term maturity and are used primarily for working capital purposes.
Our portfolio of marketable securities was invested primarily in commercial paper and U.S. corporate and U.S. treasury debt securities and is subject to market risk due primarily to changes in interest rates. Fixed rate securities may have their market value adversely affected due to a rise in interest rates. Accordingly, our future investment income may fluctuate as a result of changes in interest rates, or we may suffer losses in principal if we are forced to sell securities that decline in market value as a result of changes in interest rates. However, because we classify our marketable securities as “available for sale,” no gains or losses are recognized due to changes in interest rates unless such securities are sold prior to maturity or declines in fair value are determined to be other-than-temporary.
An immediate increase of 100 basis points in interest rates would have resulted in an $853,000 market value reduction in our investment portfolio as of September 30, 2019. This estimate is based on a sensitivity model that measures market value changes when changes in interest rates occur. Fluctuations in the value of our investment securities caused by a change in interest rates (gains or losses on the

carrying value) are recorded in other comprehensive income, and are realized only if we sell the underlying securities.
In August 2019, we issued $345.0 million aggregate principal amount of 1.125% convertible senior notes due 2026. As these Notes have a fixed annual interest rate, we have no financial or economic interest exposure associated with changes in interest rates. However, the fair value of fixed rate debt instruments fluctuates when interest rates change. Additionally, the fair value can be affected when the market price of our common stock fluctuates. We carry the Notes at face value less unamortized discount on our balance sheet, and we present the fair value for required disclosure purposes only.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Under the supervision and with the participation of our principal executive officer and principal financial officer, our management conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the period covered by this report. Our disclosure controls and procedures are intended to provide assurance at a reasonable level that the information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.
In designing and evaluating our disclosure controls and procedures, management recognizes that any disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.
Based on management’s evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures are designed to, and are effective to, provide assurance at a reasonable level that the information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.
Changes in Internal Control Over Financial Reporting
DuringUnder the quarter ended March 31, 2019,supervision and with the participation of our management, including our principal executive officer and principal financial officer, we finalized enhancementsconducted an evaluation of any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and modifications to existing internal controls15d-15(f) under the Exchange Act) that occurred during our most recently completed fiscal quarter.

Part II. Other Information
Item 1. Legal Proceedings
From time to time we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not presently a party to any legal proceedings that in the opinion of our management, if determined adversely to us, would have a material adverse effect on our business, financial condition, operating results or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.
Item 1A. Risk Factors
In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our 2018 Annual Report on Form 10-K, which could materially affect our business, financial condition or future results. Other than the item noted below, there have been no material changes during fiscal 2019 to the risk factors that were included in the Form 10-K.
Risks Related to Our Business and Industry
Our reported financial results may be adversely affected by changes in accounting principles generally accepted in the United States, including those related to leases.
Generally accepted accounting principles in the United States are subject to interpretation by the Financial Accounting Standards Board (FASB), the SEC, and various bodies formed to promulgate and interpret appropriate accounting principles. A change in these principles or interpretations could have a significant effect on our reported financial results and could affect the reporting of transactions completed before the announcement of a change.
In February 2016, the FASB issued guidance codified in ASC 842, Leases (ASU 2016-02), which amends the guidance in former ASC 840, Leases. We adopted this new standard on the effective date of January 1, 2019. The application of this guidance resulted in the addition of right-of-use assets and lease liabilities on the consolidated balance sheet. We have implemented changes to our accounting processes, internal controls and disclosures to support the new standard. See Note 1 to our accompanying condensed consolidated financial statements for information about ASU 2016-02.
Any difficulties in implementing new or revised accounting principles could cause us to fail to meet our financial reporting obligations, which could result in regulatory discipline, harm investors’ confidence in us, and adversely affect our stock price.
Our ability to use our net operating losses to offset future taxable income may be subject to certain limitations.
In general, under Section 382 of the United States Internal Revenue Code of 1986, as amended (the "Code"), a corporation that undergoes an ownership change within the meaning of Section 382 of the Code and the underlying regulations is subject to limitations on its ability to utilize its pre-change net operating losses ("NOLs"), to offset future taxable income. If our existing NOLs are subject to limitations arising from previous ownership changes, our ability to utilize NOLs could be limited by Section 382 of the Code. Future changes in our stock ownership, some of which are outside of our control, could result in an ownership change under Section 382 of the Code. Furthermore, our ability to utilize the NOLs of companies that we may acquire in the future may be subject to limitations. There is also a risk that either under prior regulations or other unforeseen reasons, our prior year NOLs could expire or otherwise be

unavailable to offset future income tax liabilities. For these reasons, we may not be able to realize a tax benefit from the use of our NOLs, whether or not we attain profitability.
We have broad discretion to use the net proceeds from the offering of our convertible senior notes, which we may not use effectively.
We intend to use the net proceeds from our convertible note offering for working capital and other general corporate purposes, as well as the acquisition of, or investment in, complementary products, technologies, solutions, or businesses, although we currently have no commitments or agreements to enter into any such transactions. The net proceeds from that offering may be invested with a view towards long-term benefits for our stockholders and this may not increase our results of operations or market value. The failure by our management to apply those funds effectively may adversely affect our operations or business prospects.
The conditional conversion feature of our convertible senior notes, if triggered, may adversely affect our financial condition and operating results.
In the event the conditional conversion feature of our convertible senior notes is triggered, holders of notes will be entitled to convert the notes at any time during specified periods at their option. If one or more holders elect to convert their notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our Class A common stock (other than paying cash in lieu of delivering any fractional share), we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity. In addition, even if holders do not elect to convert their notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the notes as a current rather than long-term liability, which would result in a material reduction of our net working capital.
Conversion of our convertible senior notes may dilute the ownership interest of our stockholders or may otherwise depress the price of our Class A common stock.
The conversion of some or all of our convertible senior notes may dilute the ownership interests of our stockholders. Upon conversion of the notes, we have the option to pay or deliver, as the case may be, cash, shares of our Class A common stock, or a combination of cash and shares of our Class A common stock. If we elect to settle our conversion obligation in shares of our Class A common stock or a combination of cash and shares of our Class A common stock, any sales in the public market of our Class A common stock issuable upon such conversion could adversely affect prevailing market prices of our Class A common stock. In addition, the existence of the notes may encourage short selling by market participants that engage in hedging or arbitrage activity, and anticipated conversion of the notes into shares of our Class A common stock could depress the price of our Class A common stock.
Certain provisions in the indenture governing the notes offered in our convertible note offering may delay or prevent an otherwise beneficial takeover attempt of us.
Certain provisions in the indenture governing our convertible senior notes may make it more difficult or expensive for a third party to acquire us. For example, the indenture governing the notes will require us to repurchase the notes for cash upon the occurrence of a fundamental change (as defined in the indenture governing the notes) of us and, in certain circumstances, to increase the conversion rate for a holder that converts its notes in connection with a make-whole fundamental change. A takeover of us may trigger the requirement that we repurchase the notes and/or increase the conversion rate, which could make it more costly for a potential acquirer to engage in such takeover. Such additional costs may have the effect of delaying or preventing a takeover of us that would otherwise be beneficial to investors.

Servicing our debt requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our substantial debt.
Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including our convertible senior notes, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. In addition, holders of the notes will have the right to require us to repurchase their notes for cash upon the occurrence of certain fundamental changes. Upon conversion of the notes, unless we elect to deliver solely shares of our Class A common stock to settle such conversion (other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of the notes being converted. Our business may not continue to generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations.
The accounting method for convertible debt securities that may be settled in cash, such as our convertible senior notes, could have a material effect on our reported financial results.
Under FASB Accounting Standards Codification 470-20, Debt with Conversion and Other Options, (ASC 470-20), an entity must separately account for the liability and equity components of convertible debt instruments (such as our convertible senior notes) that may be settled entirely or partially in cash upon conversion in a manner that reflects the issuer’s economic interest cost. ASC 470-20 requires the value of the conversion option of the notes, representing the equity component, to be recorded as additional paid-in capital within stockholders’ equity in our consolidated balance sheet and as a discount to the notes, which reduces their initial carrying value. The carrying value of the notes, net of the discount and issuance costs, will be accreted up to the principal amount of the notes from the issuance date until maturity, which will result in non-cash charges to interest expense in our consolidated statement of operations. Accordingly, we will report lower net income or higher net loss in our financial results because ASC 470-20 requires interest to include both the current period’s accretion of the debt discount and issuance costs and the instrument’s coupon interest, which could adversely affect our reported or future financial results, the trading price of our Class A common stock and the trading price of the notes.
In addition, under certain circumstances, convertible debt instruments (such as the notes) that may be settled entirely or partly in cash are currently accounted for utilizing the treasury stock method, the effect of which is that the shares issuable upon conversion of the notes are not included in the calculation of diluted earnings per share except to the extent that the conversion value of the notes exceeds their principal amount, and the effect of the conversion on diluted earnings per share is not antidilutive. Under the treasury stock method, for diluted earnings per share purposes, the transaction is accounted for as if the number of shares of Class A common stock that would be necessary to settle such excess, if we elected to settle such excess in shares, are issued. We cannot be sure that the accounting standards in the future will continue to permit the use of the treasury stock method. If we are unable to use the treasury stock method in accounting for the shares issuable upon conversion of the notes, then our diluted earnings per share would be adversely affected.
We may still incur substantially more debt or take other actions which would intensify the risks discussed above or in our Annual Report on Form 10-K.
We and our subsidiaries may incur substantial additional debt in the future, some of which may be secured debt. We will not be restricted under the terms of the indenture governing the notes from

incurring additional debt, securing existing or future debt, recapitalizing our debt, repurchasing our stock, pledging our assets, making investments, paying dividends, guaranteeing debt, or taking a number of other actions that are not limited by the terms of the indenture governing the notes that could have the effect of diminishing our ability to make payments on the notes when due.
