In addition, the amendments expanded the disclosure requirements on the analysis of stockholders' equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders' equity presented in the balance sheet at interim reporting periods must be provided in a note or separate statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is presented. The Company plans to include this presentation of interim changes in stockholders' equity in its Quarterly Report on Form 10-Q for the quarter ending March 31, 2019.
