First Coupon Date (473) and Last Coupon Date (474) are required fields for all securities that leverage the fixed income code. These fields have different names for some swaps:

• First Payment Date and Last Payment Date

• First Payment/Valuation Date and Last Payment/Valuation Date

For securities that use When using a Business Day Convention  (1536) with an adjustment, such as ADJMBC (Modified Following - Adjusted), these dates must be valid business days.In some cases, only unadjusted dates may be available in the security reference data. Eagle has functionality to calculate the adjusted dates in these cases. This can be invoked in both Issue Viewer and Message Center. Two options are available depending on your requirements:that adjusts the length of the accrual period if ends on a non-business day, Eagle Accounting requires that adjusted/actual First Coupon Date and Last Coupon Date be entered on the security master file (SMF). Other date conventions that may adjust the length of the accrual period are Day of Month Override (1533) and Interest Payment Timing (1523).

If the adjusted dates are not available during SMF setup, Eagle Accounting has functionality to calculate them based on the date-related reference data. This is used most often for swaps because they typically have a Business Day Convention of Modified Following - Ajdusted. The unadjusted First Coupon Date must be provided, which will then be adjusted and the Last Coupon Date will be populated. The fields below drive the calculation.

• Business Day Convention (1536), Day of Month Override (1533), or Interest Payment Timing (1523)
