Grading rubric

Criteria and grader verdict (showcase run)

States that the Paid-in capital of BBDC using the 9M 2025 account is 1,757,248,000
Fail
Evidence: <TEXT_RESPONSE> states “Recalculated Additional paid-in capital: $1,757,048 thousand” and “Revised APIC... = $1,757,048 thousand.” Assessment: The criterion requires stating BBDC paid-in capital using the 9M 2025 account is 1,757,248,000. The response states 1,757,048,000, which differs by 200,000, so this fails.
