Answers / Financial Due Diligence
What is the difference between a 'proof of cash' and a 'proof of concept' in the context of financial due diligence, and how would you use each to assess the target company's financial performance?
A core Financial Due Diligence interview question — asked in analyst and associate interviews across IB, PE, and the Big 4.
THE SHORT ANSWER
A 'proof of cash' refers to the verification of a company's cash flows and liquidity, while a 'proof of concept' refers to the validation of a company's business model and revenue streams. I would use a proof of cash to assess the company's ability to generate cash and meet its financial obligations, while a proof of concept would help me understand the company's revenue drivers and growth potential.
WHAT INTERVIEWERS LISTEN FOR
- ✓Proof of cash reconciles reported results to actual bank cash flows
- ✓Validates that revenue/earnings are backed by real cash
- ✓An anti-fraud and earnings-quality test
- ✓'Proof of concept' is unrelated (product viability) — a distractor
COMMON MISTAKES
- ✗Inability to verify cash flows
- ✗Unproven business model
