NOTE 1 - ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
Spok Holdings, Inc. (NASDAQ: SPOK) ("Spok," "we," "our" or the "Company"), through its wholly owned subsidiary Spok, Inc., is the global leader in healthcare communications. We deliver clinical information to care teams when and where it matters most to improve patient outcomes. Top hospitals rely on the Spok Care Connect platform to enhance workflows for clinicians, support administrative compliance, and provide a better experience for patients. Our customers send over 100 million messages each month through their Spok solutions.
We offer a focused suite of unified clinical communication and collaboration solutions that include call center operations, clinical alerting and notifications, one-way and advanced two-way wireless messaging services, mobile communications and public safety solutions.
We provide one-way and advanced two-way wireless messaging services including information services throughout the United States. These services are offered on a local, regional and nationwide basis employing digital networks. One-way messaging consists of numeric and alphanumeric messaging services. Numeric messaging services enable subscribers to receive messages that are composed entirely of numbers, such as a phone number, while alphanumeric messages may include numbers and letters, which enable subscribers to receive text messages. Two-way messaging services enable subscribers to send and receive messages to and from other wireless messaging devices, including pagers, mobile devices and personal computers. We also offer voice mail, personalized greetings, message storage and retrieval, and equipment loss and/or maintenance protection to both one-way and two-way messaging subscribers. These services are commonly referred to as wireless messaging and information services.
We also develop, sell and support enterprise-wide systems for hospitals and other organizations needing to automate, centralize and standardize clinical communications and collaboration. These solutions are used for contact centers, clinical alerting and notification, mobile communications and messaging and for public safety notifications. We offer a variety of solutions in both on-premise and Software as a Service ("SaaS") delivery models. The Spok Go platform was made commercially available in early 2020. Spok Go features an integrated cloud-native platform that is built on a foundation of a single, best-in-class architecture with hosting and security handled through our partnership with AMazonAmazon Web Services®. These areas of market focus complement the market focus of our wireless services outlined above. These products and services are commonly referred to as software solutions and services.
Basis of Presentation
The accompanying Condensed Consolidated Financial Statements include our accounts and the accounts of our wholly owned direct and indirect subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Our Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). In management's opinion, the unaudited Condensed Consolidated Financial Statements include all adjustments and accruals that are necessary for the presentation of the results of all interim periods reported herein and all such adjustments are of a normal, recurring nature with the exception of our adoption of Accounting Standards Update ("ASU") No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, often referred to as Current Expected Credit Losses ("CECL"). For additional details refer to Note 3, "Significant"Recent Accounting Policies Update"Standards".
Amounts shown on the Condensed Consolidated Statements of Operations within the operating expense categories of Cost of revenue; Research and development; Technology operations; Selling and marketing; and General and administrative are recorded exclusive of depreciation, amortization and accretion.
The financial information included herein, other than the Condensed Consolidated Balance Sheet as of December 31, 2019, is unaudited. The Condensed Consolidated Balance Sheet at December 31, 2019 has been derived from, but does not include all, the disclosures contained in the audited Consolidated Financial Statements as of and for the year ended December 31, 2019.
These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and accompanying notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2019 (the “2019 Annual Report”).

Use of Estimates
The preparation of these Condensed Consolidated Financial Statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. On an on-going basis, we evaluate estimates and assumptions, including, but not limited to, those related to the impairment of long-lived assets; intangible assets subject to amortization and goodwill; accounts receivable allowances; revenue recognition; determining standalone selling price ("SSP") of performance

UNAUDITED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)


obligations; variable consideration; depreciation expense; asset retirement obligations; income taxes; and capitalization of software costs. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
NOTE 2 - RISKS AND OTHER IMPORTANT FACTORS
See “Item 1A. Risk Factors” of Part II of this Quarterly Report on Form 10-Q (“Quarterly Report”) and "Item 1A. Risk Factors" of Part I of the 2019 Annual Report, which describe key risks associated with our operations and industry. 
NOTE 3 - RECENT ACCOUNTING STANDARDS
Recently Adopted
Credit Losses - In June 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-13, or CECL. CECL requires early recognition of credit losses on financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This guidance is effective for fiscal years beginning after December 15, 2019.


On January 1, 2020 we adopted ASU No. 2016-13 which resulted in an immaterial adjustment to the beginning balance of retained earnings and an increase to allowance for doubtful accounts.
NOTE 4 - SIGNIFICANT ACCOUNTING POLICIES UPDATE
Our significant accounting policies are detailed in Note 1, “Organization and Significant Accounting Policies” of the 2019 Annual Report. Significant changes to our accounting policies that occurred during the threesix months ended March 31,June 30, 2020 are discussed below:
Research and Development
Certain costs related to the development of Spok Go qualified for capitalization beginning in the first quarter of 2020.
In accordance with ASC 985-20, Software to be Sold, Leased, or Marketed, certain software development costs are charged to operations and expensed as incurred until technological feasibility has been established. Material costs incurred after technological feasibility is established and before the product is ready for general release are capitalized and amortized on a straight-line basis over the estimated remaining economic life of the product or the ratio of current revenues to total projected product revenues, whichever is greater. To date, the time between technological feasibility and general release to the public has been extremely short and consequently expenses available for capitalization have been immaterial. Accordingly, all research and developments costs incurred to date, accounted for in accordance with ASC 985-20, have been expensed as incurred.
In accordance with ASC 350-40, Internal-use Software, certain software development costs are capitalized while in the application development stage related to software developed for internal use or software sold in a SaaSSoftware-as-a-service ("SaaS") arrangement. This includes certain development costs for Spok Go. All other costs incurred during the preliminary project stage or the post implementationpost-implementation stage, are expensed as incurred. Capitalized software development is amortized on a straight-line basis over the estimated useful life of the asset, typically three years, beginning when those development efforts have been placed into service (e.g., generally once made commercially available). Determining the estimated useful life requires significant judgment as we consider factors such as the rapid and continuous developments in software technology, obsolescence and anticipated life of the service offering before enhancements are necessary. In a SaaS environment, customer needs are rapidly evolving and a shorter useful life is generally expected.

NOTE 5 - REVENUE, DEFERRED REVENUE AND PREPAID COMMISSIONS
Wireless Revenue
Wireless revenue consists of two2 primary components: Pagingpaging revenue and product and other revenue. Paging revenue consists primarily of recurring fees associated with the provision of messaging services and fees for paging devices and is net of a provision for service credits. Product and other revenue reflects system sales, the sale of devices and charges for paging devices that are not returned and are net of anticipated credits. Our core offering includes subscriptions to one-way or two-way messaging services for a periodic (monthly, quarterly, semiannual, or annual) service fee. This is generally based upon the type of service provided, the geographic area covered, the number of devices provided to the customer and the period of commitment. A subscriber to one-way messaging services may select coverage on a local, regional or nationwide basis to best meet their messaging needs. Two-way messaging is generally offered on a
SPOK HOLDINGS, INC.
UNAUDITED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)


nationwide basis. In addition, subscribers either contract for a messaging device from us for an additional fixed monthly fee or they own a device, having purchased it either from us or from another vendor. We also sell devices to resellers who lease or resell devices to their subscribers and then sell messaging services utilizing our networks. We offer ancillary services, such as voicemail and equipment loss or maintenance protection, which increase the monthly recurring revenue we receive along with these traditional messaging services. We offer exclusive one-way (T5) and two-way (T52) alphanumeric pagers, which are configurable to support un-encrypted or encrypted operation. When configured for encryption, they utilize AES-128 bit encryption, screen locking and remote wipe capabilities. With encryption enabled these secure paging devices enhance our service offerings to the healthcare community by adding Health Insurance Portability and Accountability Act ("HIPAA") security capabilities to the low cost, highly reliable and availability benefits of paging. (See Item 1. “Business,” in the 2019 Annual Report for more details.)
Software Revenue
Software revenue consists of two2 primary components: operations revenue and maintenance revenue. Operations revenue consists primarily of license revenues for our healthcare communications solutions, equipment revenues that facilitate the use of our software solutions, and professional services revenue related to the implementation of our solutions. Maintenance revenue is for ongoing support of our software solutions or related equipment and access to when-and-if available software updates. Maintenance is generally purchased and renewed on an annual basis.
Revenue Recognition
Revenues are recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Our software licenses and hardware are generally recognized at a point in time when we have transferred control to the customer. For software licenses, revenue is not recognized until the related license(s) has been made available to the customer and the customer can begin to benefit from its right to use the license(s). Our software licenses represent a right to use Spok’s Intellectual Property ("IP") as it exists at a point in time at which the license is granted. Many of our software licenses have significant standalone functionality due to their ability to process a transaction or perform a function or task, and we do not need to maintain those products, once provided to the customer, for value to exist. While the functionality of the IP that we license may substantively change during the license period, customers are not contractually or practically required to update their license as a result of those changes. Our wireless, professional and maintenance services are generally recognized over time due to a customer's simultaneous receipt and consumption of the benefit as we perform the work. As we transfer control over time, we recognize revenue based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires significant judgment and is based on the nature of the products or services to be provided. Generally, we use the time-elapsed measure of progress for performance obligations which include wireless or maintenance services. We believe this method best depicts the simultaneous transfer and consumption of the benefit based on our performance as these services are generally considered standby services. For professional services, we leverage an input methodology based on the number of hours worked on a project versus the total expected hours necessary to complete the project. Revenues are recognized proportionally as hours are incurred.

NOTE 6 - Leases
We have operating lease arrangements for corporate offices, cellular towers, storage units and small building space. The building space is used to house infrastructure, such as transmitters, antennae and other various equipment for the Company’s wireless paging services. For leases with a term of 12 months or less, renewal terms are generally of an evergreen nature (either month-to-month or year-to-year). For leases with a term greater than 12 months, renewal terms are generally explicit and provide for one1 to five5 optional renewals consistent with the initial term. Many of our leases, with the exception of those for our corporate offices, include options to terminate the lease within one year. Variable lease payments, residual value guarantees or purchase options are not generally present in these leases.


Lease costs are included in technology operations and general and administrative expenses on the Condensed Consolidated Statements of Operations. The following table presents lease costs disaggregated by type:

NOTE 8 - GOODWILL AND INTANGIBLE ASSETS, NET
Goodwill
During the quarterthree months ended March 31,June 30, 2020, we determined, based onperformed a qualitative assessment of goodwill and determined that the Coronavirus Disease 2019 ("COVID-19") pandemic created a triggering event that required further assessment. As such, we performed a quantitative assessment, using data as of March 31, 2020. Based on this assessment, the estimated fair value of the reporting unit exceeded the carrying value of the Company, which indicated an impairment didhad not exist as of the interim balance sheet date. For purposes of the goodwill impairment assessment, the Company as a whole is considered to be the reporting unit. The fair value of the reporting unit is estimated under a market based approach using the fair value of the Company's common stock. The estimated fair value requires significant judgments, including timing and appropriateness of the price of common stock used (e.g., point-in-time application, simple moving average, exponential moving average, etc.), as well as application of an estimated control premium. The estimated control premium is based on a number of factors including current and past market information published by third-party resources and detailed analysis that considers appropriate industry, market and other pertinent factors.occurred. While a formal impairment assessment is performed annually, the Company monitors its business environment for potential triggering events on a quarterly basis. There is potential for further impairment charges being recognized in future periods based on these ongoing assessments.
Intangible Assets
Amortizable intangible assets at March 31,June 30, 2020 related primarily to customer relationships that resulted from our acquisition of Amcom Software, Inc. in 2011. Such intangibles are being amortized over a period of ten years.years. For the years ending December 31, 2020 and 2021 there is an estimated remaining amortization of $1.9$1.3 million and $0.4 million, respectively.

Increases other than accretion, reclassification and amounts paid primarily relate to changes in estimate of the underlying liability, specifically as it relates to updates in estimated costs to remove a transmitter and the estimated timing of removal. The cost associated with the estimated removal costs and timing refinements due to ongoing network rationalization activities is expected to accrete to a total liability of $7.6 million. The total estimated liability is based on the transmitter locations remaining after we have consolidated the number of networks we operate and assume the underlying leases continue to be renewed to that future date.
Accretion expense was $0.1 million for the three months ended March 31, 2020 and 2019. Accretion expense related solely to asset retirement obligations and was recorded based on the interest method.

Employee Stock Purchase Plan.
In 2016, our Board of Directors adopted the Spok Holdings, Inc. Employee Stock Purchase Plan ("ESPP") that was subsequently approved by our stockholders on July 25, 2016. A total of 250,000 shares of common stock have been reserved for issuance under this plan.
The Company's ESPP allows employees to purchase shares of common stock at a discounted rate, subject to plan limitations. Under the ESPP, eligible participants can voluntarily elect to have contributions withheld from their pay for the duration of an offering period, subject to the ESPP limits. At the end of an offering period, contributions will be used to purchase the Company's common stock at a discount to the market price based on the first or last day of the offering period, whichever is lower. Participants are required to hold common stock for a minimum period of two years from the grant date. Participants will begin earning dividends on shares after the purchase date. Each offering period will generally last for no longer than six months. Once an offering period begins, participants cannot adjust their withholding amount. If a participant chooses to withdraw, any previously withheld funds will be returned to the participant, with no stock purchased, and that participant will be eligible to participate in the ESPP at the next offering period. If the participant terminates employment with the Company during the offering period, all contributions will be returned to the employee and no stock will be purchased at a discounted rate.
The Company uses the Black-Scholes model to calculate the fair value of the common stock to be purchased each offering period on their offer date. The Black-Scholes model requires the use of estimates for the expected term, the expected volatility of the underlying common stock over the expected term, the risk-free interest rate and the expected dividend payment.
For the three months ended March 31,June 30, 2020 and 2019, no18,586 and 9,876 shares, respectively, of the Company's common stock were purchased.purchased for a total cost of $0.2 million and $0.1 million, respectively.

NOTE 11 - INCOME TAXES
The Coronavirus Aid, Relief, and Economic Security ("CARES") Act was signed into law on March 27, 2020. The CARES Act was initiated to provide stimulus and relief in response to the COVID-19coronavirus disease 2019 ("COVID-19") pandemic and resulting economic collapse. While the CARES Act provides a number of potential benefits to companies, we believe the following items may provide certain relief for our Company:
Payroll Tax Deferral - Allows for the deferral of payment on the Company's share of the 6.2% Social Security tax on wages paid beginning on March 27, 2020 and ending on December 31, 2020. Deferred amounts are payable in two installments, with 50% of such taxes being due on December 31, 2021, and the remainder due on December 31, 2022. While we continue to assess the impact of the CARES Act, we believe this is likely to result in a deferral of between $1.5 million and $3.0 million in payroll taxes.
Employee Retention Credits - Allows for a refundable tax credit for the Company's share of the 6.2% Social Security tax on wages. This tax credit is for the first $10,000 in qualified wages paid to each employee commencing on March 13, 2020. To be eligible, our Company must (i) have had operations fully or partially suspended because of a shut-down order from a governmental authority related to COVID-19, or (ii) have had gross receipts decline by more than 50% in a calendar quarter when compared to the same quarter in 2019. Qualified wages are limited to wages paid to employees who were not providing services due to the COVID-19 crisis. While we continue to assess the impact of the CARES Act, we believe this is likely to result in a tax credit of between $0.5 million and $1.5 million.
Alternative Minimum Tax ("AMT") Credit - Allows for an immediate refund of all refundable AMT credits resulting from passage of the Tax Cuts and Jobs Act of 2017. This will result in accelerated collection of approximately $1.3 million of other current assets.
Payroll Tax Deferral - Allows for the deferral of payment on the Company's share of the 6.2% Social Security tax on wages paid beginning on March 27, 2020 and ending on December 31, 2020. Deferred amounts are payable in two installments, with 50% of such taxes being due on December 31, 2021, and the remainder due on December 31, 2022. While we continue to assess the impact of the CARES Act, we believe this is likely to result in a deferral of between $1.5 million and $3.0 million in payroll taxes. For the six months ended June 30, 2020 we have deferred approximately $0.6 million of payroll taxes under this provision.
Employee Retention Credits - Allows for a refundable tax credit for the Company's share of the 6.2% Social Security tax on wages. This tax credit is for the first $10,000 in qualified wages paid to each employee commencing on March 13, 2020. To be eligible, our Company must (i) have had operations fully or partially suspended because of a shut-down order from a governmental authority related to COVID-19, or (ii) have had gross receipts decline by more than 50% in a calendar quarter when compared to the same quarter in 2019. Qualified wages are limited to wages paid to employees who were not providing services due to the COVID-19 crisis. While we continue to assess the impact of the CARES Act, we believe this is likely to result in a tax credit of between $0.8 million and $1.5 million. For the six months ended June 30, 2020 we have claimed approximately $0.8 million in employee retention credits.

Spok files a consolidated U.S. Federal income tax return and income tax returns in various state, local and foreign jurisdictions as required.
Our quarterly tax provision, and our quarterly estimate of our annual effective tax rate, is subject to significant variation due to several factors, including variability in accurately predicting our pre-tax and taxable income and loss and the mix of jurisdictions to which they relate, changes in how we do business, changes in our stock price, foreign currency gains (losses), tax law developments (including changes in statutes, regulations, case law, and administrative practices), and relative changes of expenses or losses for which tax benefits are not recognized. Additionally, our effective tax rate can be more or less volatile based on the amount of pre-tax income or loss. For example, the impact of discrete items and non-deductible expenses on our effective tax rate is greater when our pre-tax income is lower.
For 2020, the anticipated effective income tax rate is expected to continue to differ from the Federal statutory rate of 21% primarily due to the effect of state income taxes, research and development credits, permanent differences between book and taxable income and certain discrete items.
At March 31,June 30, 2020, we had total deferred income tax assets ("DTAs") of $47.5$48.0 million and no0 valuation allowance. This reflects a decrease of $1.5$1.0 million from the December 31, 2019 DTAs of $49.0 million and no0 valuation allowance.
We consider both positive and negative evidence when evaluating the recoverability of our DTAs. The assessment is required to determine whether, based on all available evidence, it is more likely than not (i.e., greater than a 50% probability) that all or some portion of the DTAs will be realized in the future. During the fourth quarter of each year, we update our multi-year forecast of taxable income for our operations, which assists in analyzing the recoverability of our DTAs.

Business
See Note 1, "Organization and Significant Accounting Policies" in Item 1 of Part I of this Quarterly Report on Form 10-Q ("Quarterly Report") and "Item 1. Business" of Part I of the 2019 Annual Report, which describe our business in further detail.


COVID-19
The virus known as COVID-19Coronavirus disease 2019 ("COVID-19") has significantly impacted the global economy. While the United States first began experiencing an impact in late February of this year, federal and state restrictions were not widely adopted until late in the first quarter. Given the significant uncertainties that exist regarding COVID-19 it is difficult for us to predict the short and long-term implications that this pandemic will continue to have on our business. There is a high level of uncertainty around COVID-19 including, but not limited to: the length of time in which government restrictions will remain in place;place or whether the restrictions will be implemented again in certain locations; the ability to contain the spread of the virus; the time it will take for the general economy to recover; the potential for a resurgence of the virus; and the time it will take hospitals to return to a more normal operating state. As a result, we are unable to quantify the potential impact that COVID-19 may have on our business. In the short period of time that governmental restrictions have beenBeginning in place,late February, we have seen, delays inand expect to continue to see, a direct impact on our sales cycle impactingas hospitals delay purchasing decisions and deal with staff reductions. These delays impact our software bookings, which directly impacts license and equipment revenues, as well asrevenues. We have also seen, and expect to continue to see, delays in our ability to deliver on-site implementation services.services, which impacts our services revenue. While this impact was not materialmuch of our implementation process can be performed remotely, the on-premise nature of our solutions require some level of on-site availability to complete and finalize customer software solutions. We believe we will continue to see a decrease in our resultsprofessional services revenue, in comparison to normal operating levels, for the three months ended March 31, 2020,remainder of this year. Our ability to return to normal operating levels will largely be driven by our customers and their ability to bring operations back to levels beyond just critical needs and emergency services. Many hospitals have reduced or eliminated elective surgeries focusing on COVID-19 preparation and mitigation. As a result, many hospitals have temporarily furloughed employees in clinical, administrative and technology positions in order to ensure sustained cash flow during these unknown times. The personnel being furloughed are critical to both our sales cycle as well as our on-premise deployments and implementations. Additionally, many hospitals have restrictive social distancing guidelines in place in order to ensure the safety of their personnel and patients. These restrictions can make it is likelydifficult for external personnel who are not critical to havethe immediate operating needs of a greater impact onhospital, such as our results in future quartersimplementation staff, to gain access. These factors can vary considerably depending on how long these restrictions remain in place. Wethe size of an organization, geographical location and local regulations. Thus, we continue to believe there will likely be a significant impact on our software revenues for the full year ending December 31, 2020 given the continued disruptions to our business we anticipate in the second quarter and beyond.anticipate. However, with regardsregard to implementation services, these impacts are primarily a delay in timing. The revenue still resides in our backlog of performance obligations ready to deliver at some point in the future. As facts and circumstances continue to evolve over the coming months, we will continue to assess and communicate the anticipated impact on our business. While we believe revenue is likely to be impacted for the full year ending December 31, 2020, we are diligently pursuing counter measures to prudently manage operating expenses during this time, with a goal of neutralizing the impact of COVID-19 on our cash flows for the remaining ninesix months ending December 31, 2020. More specifically, the Company has enacted a Company wideCompany-wide plan that will reducereduced work schedules with a related temporary reduction in salary during the second quarter of 2020.2020 and will continue with a similar plan for the third quarter. While the Company has the ability to continue this plan for the foreseeable future, we anticipate re-evaluating our position on a quarterly basis based on the progression of COVID-19, impacts on our business, and other facts and circumstances as deemed relevant by management. Additionally, we believe the Company is likelywill continue to see some benefits from the Coronavirus Aid Relief and Economic Security ("CARES") Act discussed in further detail below.
The CARES Act was signed into law on March 27, 2020 to provide stimulus and relief in response to the COVID-19 pandemic and resulting economic collapse. While the CARES Act provides a number of potential benefits to companies, we believe the following items may provide certain relief for our Company:
Payroll Tax Deferral - Allows for the deferral of payment on the Company's share of the 6.2% Social Security tax on wages paid beginning on March 27, 2020 and ending on December 31, 2020. Deferred amounts are payable in two installments, with 50% of such taxes being due on December 31, 2021, and the remainder due on December 31, 2022. While we continue to assess the impact of the CARES Act, we believe this is likely to result in a total deferral of between $1.5 million and $3.0 million in payroll taxes. For the six months ended June 30, 2020 we have deferred approximately $0.6 million of payroll taxes under this provision.
Employee Retention Credits - Allows for a refundable tax credit for the Company's share of the 6.2% Social Security tax on wages. This tax credit is for the first $10,000 in qualified wages paid to each employee commencing on March 13, 2020. To be eligible, our Company must (i) have had operations fully or partially suspended because of a shut-down order from a governmental authority related to COVID-19, or (ii) have had gross receipts decline by more than 50% in a calendar quarter when compared to the same quarter in 2019. Qualified wages are limited to wages paid to employees who were not providing services due to the COVID-19 crisis. While we continue to assess the impact of the CARES Act, we believe this is likely to result in a tax credit of between $0.8 million and $1.5 million. For the six months ended June 30, 2020 we have claimed approximately $0.8 million in employee retention credits.
Alternative Minimum Tax ("AMT") Credit - Allows for an immediate refund of all refundable AMT credits resulting from passage of the Tax Cuts and Jobs Act of 2017. This will result in accelerated collection of approximately $1.3 million of other current assets.
Payroll Tax Deferral - Allows for the deferral of payment on the Company's share of the 6.2% Social Security tax on wages paid beginning on March 27, 2020 and ending on December 31, 2020. Deferred amounts are payable in two installments, with 50% of such taxes being due on December 31, 2021, and the remainder due on December 31, 2022. While we continue to assess the impact of the CARES Act, we believe this is likely to result in a deferral of between $1.5 and $3.0 million in payroll taxes.

Qualified wages are limited to wages paid to employees who were not providing services due to the COVID-19 crisis. While we continue to assess the impact of the CARES Act, we believe this is likely to result in a tax credit of between $0.5 and $1.5 million.
Alternative Minimum Tax ("AMT") Credit - Allows for an immediate refund of all refundable AMT credits resulting from passage of the Tax Cuts and Jobs Act of 2017. This will result in accelerated collection of approximately $1.3 million of other current assets.

As previously mentioned, we believe theseour cost mitigation efforts, in addition to relief provided by the CARES Act and natural cost savings that will materialize as a result of COVID-19 (e.g., reduced travel and events), will allow us to offset any negative cash flow impact resulting from COVID-19 for the remainder of the year.
As a result of COVID-19 it was determined that a triggering event had occurred during the three months ended March 31, 2020, requiring us to perform a quantitative goodwill assessment. However, the assessment determined that our goodwill was not impaired. Refer to Note 8, "Goodwill and Intangible Assets, Net," for further discussion.
Revenue
We offer a focused suite of unified clinical communications and collaboration solutions that include call center operations, clinical alerting and notifications, one-way and advanced two-way wireless messaging services, mobile communications and public safety solutions.

Revenue generated by the sale of our software solutions, which includes software subscription, software license, professional services (installation, consulting and training), equipment (to be used in conjunction with the software) and post-contract support (on-going maintenance), is presented as software revenue in our Statement of Operations. Our software is licensed to end users under an industry standard software license agreement. For the threesix months ended March 31,June 30, 2020, wireless revenue represented approximately 57.4%58.2% and software revenue represented approximately 42.6%41.8% of our consolidated revenue.
Refer to Note 5, "Revenue, Deferred Revenue and Prepaid Commissions" for additional information on our wireless and software revenue streams.
Operating Expenses
Our operating expenses are presented in functional categories. Certain of our functional categories are especially important to overall expense control and management. These operating expenses are categorized as follows:
Cost of revenue. These are expenses primarily for hardware, third-party software, outside services expenses and payroll and related expenses for our professional services, logistics, customer support and maintenance staff.
Research and Development. These expenses relate primarily to the development of new software products and the ongoing maintenance and enhancement of existing products. This classification consists primarily of employee payroll and related expenses, outside services related to the design, development, testing and enhancement of our solutions and to a lesser extent hardware equipment.
Technology operations. These are expenses associated with the operation of our paging networks. Expenses consist largely of site rent expenses for transmitter locations, telecommunication expenses to deliver messages over our paging networks, and payroll and related expenses for our engineering and pager repair functions. We actively pursue opportunities to consolidate

This classification consists primarily of employee payroll and related expenses, outside services related to the design, development, testing and enhancement of our solutions and to a lesser extent hardware equipment. The research and development costs are partially offset by capitalization of certain development costs for Spok Go.
Technology operations. These are expenses associated with the operation of our paging networks. Expenses consist largely of site rent expenses for transmitter locations, telecommunication expenses to deliver messages over our paging networks, and payroll and related expenses for our engineering and pager repair functions. We actively pursue opportunities to consolidate
transmitters and other technology operations expenses in order to maintain an efficient network while simultaneously ensuring adequate service for our customers. We believe continued reductions in these expenses will occur as our networks continue to be consolidated for the foreseeable future.
Selling and marketing. The sales and marketing staff are involved in selling our communication solutions primarily in the United States. These expenses support our efforts to maintain gross placements of units in service, which mitigated the impact of disconnects on our wireless revenue base, and to identify business opportunities for additional or future software sales. We have a centralized marketing function, which is focused on supporting our products and vertical sales efforts by strengthening our brand, generating sales leads and facilitating the sales process. These marketing functions are accomplished through targeted email campaigns, webinars, regional and national user conferences, monthly newsletters and participation at industry trade shows. Expenses consist largely of payroll and related expenses, commissions and other costs such as travel and advertising costs.
General and administrative. These are expenses associated with information technology and administrative functions, which include finance and accounting, human resources and executive management. This classification consists primarily of payroll and related expenses, stock-based compensation outside services expenses, taxes, licenses and permit expenses, and facility rent expenses.

The decrease in wireless revenue for the three and six months ended March 31,June 30, 2020 compared to the same periodperiods in 2019 reflects the decrease in demand for our wireless services. Wireless revenue is generally based upon the number of units in service and the monthly Average Revenue Per User ("ARPU"). On a consolidated basis, ARPU is affected by several factors, including the mix of units in service and the pricing of the various components of our services. The number of units in service changes based on subscribers added, referred to as gross placements, less subscriber cancellations, or disconnects. ARPU for the three months ended March 31,June 30, 2020 and 2019 was $7.31$7.24 and $7.32,$7.26, respectively. Total units in service were 0.9 million and 1.0 million for the three months ended March 31,June 30, 2020 and 2019, respectively. While demand for wireless services continues to decline, it has done so at a slower rate than historically experienced. While we are encouragedoptimistic that this trend will continue in future periods, we believe that demand will continue to decline for the foreseeable future in line with recent and historical trends. As our wireless products and services are replaced with other competing technologies, such as the shift from narrow band wireless service offerings to broad band technology services, our wireless revenue will continue to decrease.
The following reflects the impact of subscribers and ARPU on the change in wireless revenue:

As demand for one-way and two-way messaging has declined, we have developed or added service offerings such as encrypted paging and Spok Mobile with a pager number in order to increase our revenue potential and mitigate the decline in our wireless revenue. We will continue to explore ways to innovate and provide customers the highest value possible.


For the three and six months ended March 31,June 30, 2020, as compared to the same periodperiods in 2019, the decrease in software operationslicense revenue primarily resulted from lower license revenue. The three months ended March 31,is related to a decrease in bookings as well as the benefit received in 2019 due to amounts included a benefit from software licenses delivered to the customer which were contracted in a prior period. During the three months ended March 31, 2019, the Company began delivering software licenses to customers in the same month they were contracted for, thus a similar benefit was not seen during the three and six months ended March 31,June 30, 2020. Additionally, the delay in our sales cycle due to COVID-19 resulted in delivery of fewer software licenses and equipment products. Service revenue was lower primarily resulting from impacts of COVID-19 as a result of less efficient projectssocial distancing and other restrictions, as wellwill as initial impacts from COVID-19. Governmental travel restrictions and our customers focus on COVID-19 mitigation efforts led to delays in implementation projects, contributing to lower services revenue beginning in March.March 2020. Given the nature of our projects (e.g. fixed bid), the time taken to complete projects in comparison to the original expectation can vary significantly, resulting from a number of factors including complexity, customer focus accuracy of the original scope, etc. Additionally, we significantly increased capacity in the fourth quarter of 2019. Some of this inefficiency seen in the first quarter can be attributed to the significant training and other efforts undertaken by the services team as these new hires were


assimilated into the professional service organization. Our current expectation is that these individuals will be fully utilized beginning in the second quarter of 2020, excluding any effects from COVID-19.project scope.
For the three and six months ended March 31,June 30, 2020 as compared to the same period in 2019, the decrease in maintenance revenue primarily relates to lower license bookings, as discussed above, from which new maintenance revenue is derived and certain one-time revenue items reflected in the results for the threesix months ended March 31,June 30, 2019 that did not occur during the first quarter ofin 2020. These one-time items generally relate to specific renewal contracts that do not have auto-renewal terms and for which we must negotiate for at the end of each term. We are generally precluded from recognizing revenue on these contracts until new terms have been agreed to even though we generally will continue to provide maintenance service for these customers while negotiations are on-going. While certain of our commercial customers require this type of contract renewal, these contracts are generally limited to government organizations including federal, state and local entities. When a renewal of this nature has been contracted, it is often accompanied by several months of "catch-up" revenue from services performed in past periods resulting in a one-time value that is greater than the normal monthly revenue expected over the life of the remaining term. As we continue to focus the majority of our development efforts on Spok Go, we anticipate a continued decline in our ability to sell new licenses for the Care Connect Suite of products. While we have not seen a meaningful increase in our normal customer churn, our ability to replace this churn with new revenues will not likely replicate what we have accomplished historically nor do we expect to fully offset this with annual increases of our existing base. Our intent is to replace this churn with the sale of Spok Go as well as transition existing on-premise customers to our cloud based solution over the next several years. Given these dynamics, we believe annual maintenance revenue is likely to be relatively flat or slightly down as we move forward, especially as we begin the process of transitioning existing customers to a subscription model.

Research and development expenses decreased for the three and six months ended March 31,June 30, 2020 compared to the same periodperiods in 2019 primarily due to the capitalization of certain development costs related to Spok Go, as development efforts reached project phases where certain costs qualified for capitalization.Go. Refer to Note 4, "Significant Accounting Policies Update" and Note 7, "Consolidated Financial Statement Components" for further detail. The capitalization of development costs partially offset anticipated increases in payroll and related compensation expenses,costs decreased primarily as wea result of temporary cost reductions implemented by management beginning in the second quarter of 2020, in an effort to negate the impacts of COVID-19. These temporary cost reductions are outlined in more detail within our earlier discussion on COVID-19. We continue to focus on the development efforts of our software solutions. Wesolutions and intend to maintain these efforts based on their importance to our continued success and do not anticipate a return to historically low costs.success.

Technology operations expense increaseddecreased for the three and six months ended June 30, 2020 compared to the same periods in 2019, primarily due to the decrease in payroll and related, and other minor expenses, as well as a decrease in site rent for the three months period. The payroll and related costs decreased primarily as a result of temporary cost reductions implemented by management beginning in the second quarter of 2020, in an effort to negate the impacts of COVID-19. These temporary cost reductions are outlined in more detail within our earlier discussion on COVID-19. The decrease in site rent for the three months ended March 31,June 30, 2020 compared to the same period in 2019 is primarily due to a reduction in the increase innumber of active transmitters, which directly impacts the amount of site rent and other minor expenses. The increase in site rent is primarily related toexpense we incur on a one time reduction made during the first quarter of 2019 which did not similarly impact the first quarter of 2020. Excluding this one time reduction, site rent costs decreased as a result of our continued efforts related to network rationalization.recurring basis. The number of active transmitters declined 2.5% in March 31,2.8% between June 30, 2020 compared to March 31,and June 30, 2019. The number of active transmitters directly relates to the amount of site rent expenses we generally incur on a recurring basis. As we reach certain minimum frequency commitments, as outlined by the United States Federal Communications Commission, we may be unable to continue our efforts to rationalize and consolidate our networks.

Selling and marketing expenses increaseddecreased for the three and six months ended March 31,June 30, 2020 compared to the same periodperiods in 2019, primarily due to the increasedecrease in payroll and related, and other various expenses, partially offset by the decrease in commissions and advertising and events. The increase in payroll and related costs decreased primarily as a result of temporary cost reductions implemented by management beginning in the second quarter of 2020, in an effort to negate the impacts of COVID-19. These temporary cost reductions are outlined in more detail within our earlier discussion on COVID-19. The decrease in commissions expenses is primarily relatedrelates to an increasea corresponding decrease in headcount.revenue. The decrease in advertising and events expenses is largely due to management's focused efforts to reduce marketing costs to augment research and development initiatives. The decrease in commissions expenses primarily relates to the decrease in revenue and the related commissions associated with those revenues.

General and administrative expenses increaseddecreased for the three and six months ended March 31,June 30, 2020 compared to the same periodperiods in 2019, primarily due to a decrease in payroll and related and various other expenses, partially offset by an increase in stock-based compensation.compensation and bad debt. The payroll and related costs decreased primarily as a result of temporary cost reductions implemented by management beginning in the second quarter of 2020, in an effort to negate the impacts of COVID-19. These temporary cost reductions are outlined in more detail within our earlier discussion on COVID-19. The increase in bad debt is partly due to a change in our methodology resulting from the adoption of CECL as we now carry an allowance for current an unbilled receivables which did not occur for the same periods in 2019. The decrease in facility rent, office, and technology costs is largely due miscellaneous expense reductions stemming from management's cost saving efforts. For the six months ended June 30, 2020, the increase in stock-based compensation iswas largely due to forfeitures related to the resignation of an NEONamed Executive Officer ("NEO") during the threesix months ended March 31,June 30, 2019 that did not impactoccur during the threesix months ended March 31,June 30, 2020.
Depreciation, Amortization and Accretion. Depreciation, amortization and accretion expenses were $2.1 million and $2.4$2.3 million for the three months ended March 31,June 30, 2020 and 2019, respectively, and $4.2 million and $4.7 million for the six months ended June 30, 2020 and 2019, respectively. The decrease of $0.3$0.2 million in depreciation, amortization and accretion expenses for the three months ended March 31,June 30, 2020 compared to the same period in 2019 isand the decrease of $0.5 million for the six months ended June 30, 2020 compared to the same period in 2019 are primarily due to certain computer hardware and software assets becoming fully depreciated in 2019 and continued efforts to reduce capital expenditures. For additional details regarding depreciation, amortization and accretion expenses refer to Note 7, "Consolidated Financial Statement Components."
Provision for


Benefit from (provision for) income taxes. ExpenseBenefit from income taxes was $0.7$0.4 million and $0.6$0.3 million for the three months ended March 31,June 30, 2020 and 2019, respectively. Income tax expensebenefit increased $0.1 million for the three months ended March 31,June 30, 2020 compared to the same period in 2019. Expense from income taxes was $0.3 million for the six months ended June 30, 2020 and 2019. The change in the provision for income taxes for the three and six months ended March 31,June 30, 2020 as compared to the same period in 2019 primarily relates to the difference in the anticipated annual effective tax rate as a result of certain permanent tax differences, estimated research and development tax credits and certain discrete items. Further details can be found in Note 11, "Income Taxes."
Liquidity and Capital Resources
At March 31,June 30, 2020, we had cash and cash equivalents and short-term investments of $72.2$70.9 million.
The available cash and cash equivalents are held in accounts managed by third-party financial institutions and consist of invested cash and cash in our operating accounts. The invested cash is invested in interest bearing funds managed by third-party financial institutions. These funds invest in direct obligations of the government of the United States. To date, we have experienced no loss or lack of access to our invested cash or cash equivalents; however, we can provide no assurance that access to our invested cash and cash equivalents will not be impacted by adverse market conditions. Our short-term investments consist entirely of U.S. Treasury securities which are classified as held-to-maturity and are measured at amortized cost on our Condensed Consolidated Balance Sheets.
At any point in time, we have approximately $7.0 million to $12.0 million in our operating accounts that are with third-party financial institutions. While we monitor daily the cash balances in our operating accounts and adjust the cash balances as appropriate, these cash balances could be impacted if the underlying financial institutions fail or are subject to other adverse conditions in the financial markets. To date, we have experienced no loss or lack of access to cash in our operating accounts.
We intend to use our cash on hand to provide working capital, to support operations, to invest in our business, and to return value to stockholders through cash dividends and possible repurchases of our common stock. We may also consider using cash to fund or complete opportunistic investments and acquisitions that we believe will provide a measure of growth or revenue stability while supporting our existing operations. Because we intend to continue to substantially invest in the development of our integrated communications platform over the next several years, commensurate with declining revenues from our wireless business, we anticipate that our cash on hand will decrease significantly during that period, and possibly longer until revenues from Spok Go begin to be realized.
In response to COVID-19, management has enacted certain cost mitigation measures, as previously discussed, that it believes will allow the Company to operate in a cash flow positive manner for the remainder of the year. While we had previously mentioned the potential impact on our revenues, we do not expect COVID-19 will have a material impact on our liquidity at this time given our ability to reduce costs further, if necessary.


Overview
In the event that net cash provided by operating activities and cash on hand are not sufficient to meet future cash requirements, we may be required to reduce planned capital expenses, reduce or eliminate our cash dividends to stockholders, not resume our common stock repurchase program, sell assets and/or seek outside financing. We can provide no assurance that reductions in planned capital expenses or proceeds from asset sales would be sufficient to cover shortfalls in available cash or that outside financing would be available on acceptable terms.
Based on current and anticipated levels of operations, we anticipate net cash provided by operating activities, together with the available cash on hand at March 31,June 30, 2020, should be adequate to meet our anticipated cash requirements for the foreseeable future.


The following table sets forth information on our net cash flows from operating, investing, and financing activities for the periods stated:

This cash dividend of approximately $2.4 million will be paid from available cash on hand.
Other. For 2020, the Board of Directors currently expects to pay dividends of $0.125 per common share each quarter, subject to declaration by the Board of Directors.
Commitments and Contingencies
Operating Leases. We have operating leases for office and transmitter locations. Substantially all of these leases have lease terms ranging from one month to five years. We continue to review our office and transmitter locations, and intend to replace, reduce or consolidate leases, where possible. As we reach certain minimum frequency commitments, as outlined by the United States Federal Communications Commission, we may be unable to continue our efforts to rationalize and consolidate our networks. Total rent expense under operating leases was $4.2$4.3 million and $4.5 million for the three months ended March 31,June 30, 2020 and 2019, respectively and $8.6 million and $8.7 million for the six months ended June 30, 2020 and 2019, respectively.
Off-Balance Sheet Arrangements. We do not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, whichthat would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, we are not exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.


Commitments and Contingencies. See Note 12, "Commitments and Contingencies" for further discussion on our commitments and contingencies.

Critical Accounting Policies and Estimates
The preceding discussion and analysis of financial condition and operations is based on our Condensed Consolidated Financial Statements, which have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of our Condensed Consolidated Financial Statements requires management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures. On an on-going basis, we evaluate estimates and assumptions, including, but not limited to, those related to the impairment of long-lived assets and intangible assets subject to amortization and goodwill, accounts receivable, revenue recognition, asset retirement obligations, and income taxes. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
There have been no changes to the critical accounting policies reported in the 2019 Annual Report that affect our significant judgments and estimates used in the preparation of our Condensed Consolidated Financial Statements other than those outlined in Note 4, "Significant Accounting Policies Update."
ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Interest Rate Risk
As of March 31,June 30, 2020, we had no outstanding debt and no revolving credit facility.
Foreign Currency Exchange Rate Risk
We conduct a limited amount of business outside the United States. The financial impact of transactions billed in foreign currencies is immaterial to our financial results and, consequently, we do not have any material exposure to the risk of foreign currency exchange rate fluctuations.
ITEM 4.   CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
Our management carried out an evaluation, as required by Rule 13a-15(b) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), with the participation of our principal executive officer and our principal financial officer, of the effectiveness of our disclosure controls and procedures, as of the end of our last fiscal quarter. Disclosure controls and procedures are defined under Rule 13a-15(e) under the Exchange Act as controls and other procedures of an issuer that are designed to ensure that the information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act (i) is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (ii) is accumulated and communicated to the issuer’s management, including its principal executive officer and principal financial officer, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure. Based upon this evaluation, our principal executive officer and our principal financial officer have concluded that our disclosure controls and procedures were effective as of March 31,June 30, 2020.
Changes in Internal Control Over Financial Reporting
There were no changes made to the Company’s internal control over financial reporting during the three months ended March 31,June 30, 2020 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Refer to Note 12, "Commitments and Contingencies" in the Notes to Financial Statements for information regarding legal proceedings in which we are involved.
ITEM 1A. RISK FACTORS
The risk factors included in “Part I – Item 1A – Risk Factors” of the 2019 Annual Report have not materially changed during the quartersix months ended March 31,June 30, 2020 other than the additional risk factor provided below:
Our business, financial condition and operating results have been, and will continue to be, adversely affected by the recent COVID-19 pandemic.
The COVID-19 pandemic has resulted in a widespread health crisis that has adversely affected businesses, economies and financial markets worldwide, and has caused significant volatility in U.S. and international debt and equity markets. In particular, health care organizations, have faced, and will continue to face, substantial challenges in treating patients with COVID-19, such as the diversion of hospital staff and resources from ordinary functions to the treatment of COVID-19, supply, resource and capital shortages and the overburdening of staff and resource capacity.
Our business, financial condition and operating results have been, and will continue to be, adversely affected by the COVID-19 pandemic. For example, the COVID-19 pandemic has caused, and will continue to cause, delays in or the loss of revenue from services that require onsite implementation as well as delays in or the loss of software bookings, which directly impacts license and equipment revenues, as health care organizations are putting these projects on hold to focus limited resources and personnel capacity toward the treatment of COVID-19. We also may be affected by the cancellation of or delay in healthcare information technology and management systems conferences and exhibitions, like the Healthcare Information and Management Systems Society (HIMSS) Global Health Conference & Exhibition, which was scheduled to take place in early March and would have allowed us to continue the rollout of Spok Go. The cancellation of or delay in these types of conferences and exhibitions may negatively affect our growth in Spok Go revenues.
The extent to which COVID-19 impacts our results will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of COVID-19 and the actions taken to contain itCOVID-19 or treat its impact.impact and the length of time any government restrictions will remain in place, whether restrictions will be implemented again in certain locations, the time it will take for the general economy to recover, the potential for a resurgence of the virus and the time it will take hospitals to return to a more normal operating state.
ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
