You submit a Performance Calculation report with your calculation criteria. The return calculations you use vary, depending on the types of returns you are calculating. The report uses accounting and benchmark data stored in the data warehouse to calculate returns, and lets you commit the single-period returns to the PERFORM database. The PERFORM database stores single-period returns and weights for portfolios, composites, and standard and custom indexes, along with performance market values, and other performance specific data.
Eagle uses the term commit to identify the act of storing performance information in the PERFORM database for use in analysis and reporting. When you commit data, you can store returns, as well as supporting data like the beginning and ending market values, and net inflows and outflows. You can set up certain performance return upload processes and Performance Calculation reports to automatically commit performance data or to prevent automatic commitment. This allows you to commit data manually as part of your audit and control workflows, or to avoid commitment entirely under certain conditions. Once you commit the returns, you can use them for presentation purposes. Or geometrically link a set of returns for multi-period analysis using the Performance Analysis report.
Eagle's Equity Attribution and Fixed Income Attribution components build their analysis results from the standard outputs of the performance calculation and commit process.
