Task prompt
What the agent was asked to do
Please use the LBO model to calculate the sponsor equity value and IRR for Year 5. Then report the sponsor equity value in US dollars, rounded to the nearest million (e.g., $1,000). Also, report the IRR as a percentage rounded to one decimal place. Send me your reply here. Follow these steps: - Increase the Senior Debt leverage to 6.0x from 5.0x. - Decrease the Senior Debt interest rate to 6.0% from 7.5%. - Reflect mandatory annual amortization of the Senior Debt, calculated as 2.0% of the opening principal balance of 2,088.3. - Increase the Subordinated Debt leverage to 2.0x from 1.5x. - Decrease the Subordinated Debt interest rate to 8.0% from 10.0%.
