our Chief Financial Officer concluded that our internal control over financial reporting was effective to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of our financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Ernst & Young LLP, the independent registered public accounting firm that audited our consolidated financial statements included in this annual report on Form 10-K, has issued an attestation report on the effectiveness of internal control over financial reporting as of December 31, 2017 which is included in ‘‘Item 8. Financial Statements and Supplementary Data.’’ Item 9B. Other Information Disclosures Required Pursuant to Section 13(r) of the Securities Exchange Act of 1934 Under the Iran Threat Reduction and Syria Human Rights Act of 2012, which added Section 13(r) of the Exchange Act, we are required to include certain disclosures in our periodic reports if we or any of our ‘‘affiliates’’ (as defined in Rule 12b-2 under the Exchange Act) knowingly engaged in certain specified activities during the period covered by the report. Because the Securities and Exchange Commission (‘‘SEC’’) defines the term ‘‘affiliate’’ broadly, it includes any entity controlled by us as well as any person or entity that controls us or is under common control with us (‘‘control’’ is also construed broadly by the SEC). We are not presently aware that we and our consolidated subsidiaries have knowingly engaged in any transaction or dealing reportable under Section 13(r) of the Exchange Act during the fiscal quarter ended December 31, 2017. In addition, except as described below, at the time of filing this annual report on Form 10-K, we are not aware of any such reportable transactions or dealings by companies that may be considered our affiliates as to whether they have knowingly engaged in any such reportable transactions or dealings during such period. Upon the filing of periodic reports by such other companies for the fiscal quarter or fiscal year ended December 31, 2017, as the case may be, additional reportable transactions may be disclosed by such companies. As of December 31, 2017, funds affiliated with Warburg Pincus (‘‘Warburg Pincus’’) held approximately 24% of our outstanding common shares. We are also a party to a shareholders agreement with Warburg Pincus pursuant to which, among other things, Warburg Pincus currently has the right to designate two members of our board of directors. Accordingly, Warburg Pincus may be deemed an ‘‘affiliate’’ of us, both currently and during the fiscal quarter ended December 31, 2017. Disclosure relating to Warburg Pincus and its affiliates Warburg Pincus informed us of (i) the information reproduced below (the ‘‘SAMIH Disclosure’’) regarding Santander Asset Management Investment Holdings Limited (‘‘SAMIH. SAMIH is a company that may be considered an affiliate of Warburg Pincus. Because we and SAMIH may be deemed to be controlled by Warburg Pincus, we may be considered an ‘‘affiliate’’ of each of SAMIH for the purposes of Section 13(r) of the Exchange Act. SAMIH Disclosure: Quarter ended December 31, 2017 ‘‘Santander UK plc (‘‘Santander UK’’) holds two savings accounts and one current account for two customers resident in the United Kingdom (‘‘UK’’) who are currently designated by the United States (‘‘US’’) under the Specially Designated Global Terrorist (‘‘SDGT’’) sanctions program.
