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.

Grading rubric

Criteria and grader verdict (showcase run)

States that BBDC accretion / dilution is 36.83% for 10.0% Bid Premium and 15.0% Cash Consideration
Pass
Evidence: In the BBDC table, the row “15%” cash consideration under “10% Bid Premium” shows “36.83%.” Assessment: Criterion asks whether it states BBDC accretion/dilution is 36.83% for 10.0% bid premium and 15.0% cash consideration; pass.
States that BBDC accretion / dilution is 36.41% for 10.0% Bid Premium and 10.0% Cash Consideration
Pass
Evidence: In the BBDC table, the row “10%” cash consideration under “10% Bid Premium” shows “36.41%.” Assessment: Criterion asks whether it states BBDC accretion/dilution is 36.41% for 10.0% bid premium and 10.0% cash consideration; pass.
States that BBDC accretion / dilution is 33.64% for 20.0% Bid Premium and 10.0% Cash Consideration
Pass
Evidence: In the BBDC table, the row “10%” cash consideration under “20% Bid Premium” shows “33.64%.” Assessment: Criterion asks whether it states BBDC accretion/dilution is 33.64% for 20.0% bid premium and 10.0% cash consideration; pass.
States that BBDC accretion / dilution is 34.05% for 20.0% Bid Premium and 15.0% Cash Consideration
Pass
Evidence: In the BBDC table, the row “15%” cash consideration under “20% Bid Premium” shows “34.05%.” Assessment: Criterion asks whether it states BBDC accretion/dilution is 34.05% for 20.0% bid premium and 15.0% cash consideration; pass.
States that TVPG accretion / dilution is 46.05% for 10.0% Bid Premium and 10.0% Cash Consideration
Pass
Evidence: In the TVPG table, the row “10%” cash consideration under “10% Bid Premium” shows “46.05%.” Assessment: Criterion asks whether it states TVPG accretion/dilution is 46.05% for 10.0% bid premium and 10.0% cash consideration; pass.
States that TVPG accretion / dilution is 44.44% for 10.0% Bid Premium and 15.0% Cash Consideration
Pass
Evidence: In the TVPG table, the row “15%” cash consideration under “10% Bid Premium” shows “44.44%.” Assessment: Criterion asks whether it states TVPG accretion/dilution is 44.44% for 10.0% bid premium and 15.0% cash consideration; pass.
States that TVPG accretion / dilution is 56.33% for 20.0% Bid Premium and 10.0% Cash Consideration
Pass
Evidence: In the TVPG table, the row “10%” cash consideration under “20% Bid Premium” shows “56.33%.” Assessment: Criterion asks whether it states TVPG accretion/dilution is 56.33% for 20.0% bid premium and 10.0% cash consideration; pass.
States that TVPG accretion / dilution is 54.73% for 20.0% Bid Premium and 15.0% Cash Consideration
Pass
Evidence: In the TVPG table, the row “15%” cash consideration under “20% Bid Premium” shows “54.73%.” Assessment: Criterion asks whether it states TVPG accretion/dilution is 54.73% for 20.0% bid premium and 15.0% cash consideration; pass.
