Item 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of December 31, 2018, management carried out, under the supervision and with the participation of our principal executive officer and principal financial officer, 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 Securities Exchange Act of 1934). Based on this evaluation, our principal executive officer and principal financial officer concluded that, as of December 31, 2018, our disclosure controls and procedures were effective in ensuring that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in applicable rules and forms and are designed to ensure that information required to be disclosed in those reports is accumulated and communicated to management, including our principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

Management's Report on Internal Control over Financial Reporting

Our management team is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2018. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in the Internal Control — Integrated Framework (2013).

We completed acquisitions of AdvancedMD and SICOM in the third and fourth quarters of 2018, respectively. As permitted by the SEC rules and regulations, management's assessment did not include the internal control of the acquired operations of these acquired businesses which are included in our consolidated financial statements as of December 31, 2018 and for the periods from the acquisition dates through December 31, 2018. In accordance with our integration efforts, we plan to incorporate the operations of the acquired businesses into our internal control over financial reporting program within the time period provided by applicable SEC rules and regulations. The assets, excluding goodwill, of these acquired businesses constituted approximately 5% of our total consolidated assets as of December 31, 2018. These acquired businesses comprised less than 2% of our total consolidated revenues and did not contribute to our consolidated operating income for the year ended December 31, 2018.

Based on the results of its evaluation, which excluded assessments of the internal control of the acquired operations of AdvancedMD and SICOM, management believes that as of December 31, 2018, our internal control over financial reporting is effective based on those criteria.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect all misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate. Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Due to such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, such risk.

Deloitte & Touche LLP has issued an attestation report on our internal control over financial reporting, which is included herein as the Report of Independent Registered Public Accounting Firm under Item 8 - Financial Statements and Supplementary Data for the year ended December 31, 2018.

Changes in Internal Control over Financial Reporting

On September 1, 2017, we completed our acquisition of ACTIVE Network, which we have since been integrating into our North America segment. As part of our integration activities, we have completed the incorporation of ACTIVE Network's operations into our internal control over financial reporting program.

In the fourth quarter of 2018, we completed our acquisition of SICOM, which is being integrated into our North America segment. In accordance with our integration efforts, we plan to incorporate the operations of SICOM into our internal control over financial reporting program within the time period provided by the applicable SEC rules and regulations.

In the fourth quarter of 2018, we also added internal controls over disclosure related to the expected accounting and reporting effects of the new lease accounting standard, which is effective for us on January 1, 2019. We also implemented a new technology solution to assist with the necessary calculations to support the accounting and disclosure requirements of the new lease accounting standard.
