Task prompt

What the agent was asked to do

Use the LBO model to assess the impact of a lower interest rate environment on the Year 5 exit IRR% target. 1. Decrease the existing senior debt cost by 50 bps starting at the beginning of Year 2. The senior debt cost should remain constant thereafter. 2. Decrease the existing subordinated debt cost by 25 bps starting at the beginning of Year 3. The subordinated debt cost should remain constant thereafter. 3. Recalculate the total interest cost for the impacted projection period (Year 2 to Year 5). 4. Note that all interest expense calculations must be based on the average of the beginning and ending debt balance in the period. Tell me the Net Debt at Exit, Sponsor Equity Value at Exit, MOIC, and IRR %. Print it here. All monetary results must be displayed in USD millions, rounded to two decimal places, and all percentages and multiples must also be rounded to two decimal points.
