Task prompt
What the agent was asked to do
Replace the risk-free rate in the DCF model with the average of the 10 year and 20 year treasury rates as of 12/22/2025, and assume that the cost of debt is this average value plus 150 basis points. Finally, assume that the tax rate is revised up by 50 basis points for the projection period. What is the absolute difference in terminal value in the original calculation and this updated one?
