Table of Contents Management's Plan for Remediation of the Material Weakness Changes in Internal Control over Financial Reporting ITEM 9B. OTHER INFORMATION 174 None. There were no changes in our internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)) during the quarter ended December 31, 2018, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. The remediation efforts are intended both to address the identified material weakness and to enhance our overall financial control environment. Management is committed to continuous improvement of the company’s internal control over financial reporting and will continue to diligently review the company’s internal control over financial reporting.  In response to the material weakness described above, with the oversight of the Audit Committee of our Board of Directors, management is currently evaluating our policies and procedures related to the accounting for income taxes and plans to design and implement adequate internal controls to ensure that (i) the income tax effects of acquired partnership interests are properly accounted for and disclosed in the period of acquisition, and (ii) the resulting investment in partnership deferred income tax assets and liabilities are assessed and reconciled periodically to the book-tax differences in the underlying assets and liabilities within the partnership to determine whether any adjustment is necessary. An independent registered public accounting firm, PricewaterhouseCoopers LLP, has audited the effectiveness of our internal control over financial reporting as of December 31, 2018, as stated in their report which appears in Part II—Item 8 Financial Statements and Supplementary Data. As a result of the material weakness in internal control over financial reporting described above, management has concluded that we did not maintain effective internal control over financial reporting as of December 31, 2018. years ended December 31, 2017, and December 31, 2016, and the correction of the unaudited quarterly financial information for fiscal years 2018 and 2017. Additionally, this material weakness could result in misstatements to the aforementioned account balances or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.
