Accounting Policies [Abstract] |
Organization and Significant Accounting Policies | ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES Spok Holdings, Inc. (NASDAQ: SPOK) ("Spok," "we," "our" or the "Company"), through its wholly owned subsidiary Spok, Inc., is proud to be 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 Spok products and services to enhance workflows for clinicians, support administrative compliance, and provide a better experience for patients. We offer a focused suite of unified clinical communication and collaboration solutions that include call center applications, 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, personal digital assistants 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. These solutions are used for contact centers, clinical alerting and notification, mobile communications and messaging and for public safety notifications. These areas of market focus complement the market focus of our wireless services outlined above. 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 the revision to deferred revenue as discussed in more detail below. Amounts shown in 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 and accretion. These items are shown separately to the extent that they are considered material for the periods presented. The financial information included herein, other than the Condensed Consolidated Balance Sheet as of December 31, 2022, is unaudited. The Condensed Consolidated Balance Sheet as of December 31, 2022, 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, 2022. 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, 2022 (the “2022 Annual Report”). The Condensed Consolidated Statements of Operations for the interim periods presented are not necessarily indicative of the results that may be expected for a full year. Revision of Previously Issued Financial Statements In connection with the preparation of its financial statements for the quarter ended June 30, 2023, the Company identified certain adjustments to correct an immaterial error related to the understatement of deferred revenue of approximately $1.0 million. These adjustments corrected an overstatement of our software revenue in 2018 stemming from non-recurring activity associated with the implementation of a new financial system in 2017. Based on our quantitative and qualitative analysis, we concluded that the adjustments were not material to any prior annual or interim periods. As such, we have revised the Condensed Consolidated Balance Sheets for the year ended December 31, 2022, relevant footnotes, and other financial information as applicable, included herein to reflect the reduction in opening retained earnings and a corresponding increase to deferred revenue. 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 ongoing basis, we evaluate estimates and assumptions, including, but not limited to, those related to the impairment of long-lived assets, goodwill, accounts receivable allowances, revenue recognition, determining the standalone selling price of performance obligations, variable consideration, depreciation expense, 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.
