Guidance for non-GAAP operating margin, non-GAAP net income attributable to BlackLine, and non-GAAP net income per share attributable to BlackLine excludes specified items from the corresponding GAAP financial measures as outlined below under "Use of Non-GAAP Financial Measures" and as detailed in the reconciliations of non-GAAP measures for historical periods. Reconciliations of non-GAAP operating margin, non-GAAP net income attributable to BlackLine, and non-GAAP net income per share attributable to BlackLine guidance to the most directly comparable U.S. GAAP measures are not available on a forward-looking basis without unreasonable efforts due to the unpredictability and complexity of the charges excluded from these non-GAAP financial measures. The Company expects the variability of the above items could have a significant, and potentially unpredictable, impact on its future GAAP operating margin, net income attributable to BlackLine, and net income per share attributable to BlackLine.
