Task prompt

What the agent was asked to do

Using the merger model, recalculate the post-deal pro forma balance sheet in the “Post-Deal Proforma” tab under the following assumptions: - 50% cash consideration - 20% of balance sheet cash is used in the transaction - BBDC share price declines by 5% post-deal - New shares are issued at the updated (post-decline) share price Print back for me here: 1. Pro forma NAV per share 2. Pro forma Debt-to-Equity ratio Round both the per-share figure and the ratio to two decimal places.
