Task prompt

What the agent was asked to do

Calculate the accretion / dilution of both BBDC and TVPG shareholders, sensitized for different Cash consideration and Bid Premium. Edit the existing merger model and add two sensitivity analyses: one showing BBDC accretion/dilution and one showing TVPG accretion/dilution, each sensitized to bid premium (10% and 20%) and cash consideration (10% and 15%). Assume an increase of EBIT Synergies by 480bps and a 210bps decrease in post-deal bidder share price downside. All output values should be in %, rounded to 2 decimal places.
