In short

What is financial due diligence?

Financial due diligence is an independent review of a company’s financial position before a deal. It tests the quality of earnings (the profit the business will keep making), net debt and debt-like items, and normal working capital, so the price reflects sustainable performance. It differs from an audit, which checks that past accounts are fairly stated; due diligence asks what the numbers mean for the price.

    Questions

    What clients ask about financial due diligence.

    What is financial due diligence?

    Financial due diligence is an independent review of a target’s earnings, cash, debt and working capital before a deal, so the buyer pays for sustainable performance. The findings feed directly into the price and the sale and purchase agreement.

    How is due diligence different from an audit?

    An audit gives an opinion on whether past financial statements are fairly presented. Due diligence looks forward: it adjusts earnings to what the business will keep making, identifies debt-like items and sets normal working capital, all for the purpose of the price.

    What is a quality of earnings review?

    A quality of earnings review adjusts reported profit, usually EBITDA, for one-off, non-recurring and non-arm’s-length items, to show the sustainable earnings a valuation should be based on.

    How long does financial due diligence take?

    Usually three to six weeks for a mid-market target, depending mostly on how complete the data room is and how quickly management can answer questions.

    What is vendor due diligence?

    Vendor due diligence is commissioned by the seller before the sale. It gives buyers a common, independent starting point, shortens the process and lets the seller address findings before they affect the price.

    Who relies on the report?

    The buyer’s board and investment committee, lenders and co-investors. With a vendor report, buyers may also rely on it under a reliance letter.
