Private equity investment and the accounts work behind a deal

Private equity investors buy large or controlling stakes in more mature businesses. We prepare the accounts, schedules and forecasts a deal is priced from.

Private equity is medium to long-term finance for more mature businesses, often through a buy-out, and usually takes a large or controlling stake. Investors typically hold for 4 to 7 years. The price is usually set by a locked box or by completion accounts.

Both methods work from the company's records of earnings, working capital and net debt, so those records need to be complete and reconciled before a buyer starts its review.

Private equity and venture capital compared

  • Often through a buy-out or buy-in
  • Usually a large or controlling stake

Buy-outs

A buy-out means buying a majority stake in a business, often more than 50%. When the existing management buys the business it is a management buy-out, and when the purchase is mostly funded by debt it is a leveraged buy-out (British Business Bank).

Exits happen through a stock market listing, a sale to a trade buyer or a sale to another investor, so the investor will want accounts and reporting that will stand up to the next buyer's checks too.

Locked box and completion accounts

Locked box

The price is fixed from accounts at an earlier date

  • Used in UK and European deals
  • An equity ticker can pass cash profits made after the locked box date to the seller
  • More certainty over the price
  • More risk for the buyer if the business gets worse before completion

Completion accounts

The price is set from accounts drawn up at completion

  • Adjusted for the actual net debt and working capital
  • More accurate
  • Slower
  • More open to disputes after completion

Locked box: ICAEW Guideline 71.

The accounts work before and during a deal

  1. 1
    Monthly management accounts

    Accounts closed every month and reconciled, so the history the buyer reviews is complete.

  2. 2
    One-off items identified

    Unusual income and costs listed with their evidence, so underlying earnings can be worked out.

  3. 3
    Working capital and net debt

    Month-end schedules of debtors, creditors, stock, borrowing and debt-like items, which feed either the locked box accounts or the completion accounts.

  4. 4
    A forecast

    A monthly forecast of profit and cash with its assumptions written down.

  5. 5
    Tax position

    Corporation tax, VAT and PAYE up to date, with any open enquiries and reliefs claimed set out.

We quote this work in writing once we know the size of the business and the deal.

Common questions

What is the difference between private equity and venture capital?

The British Business Bank describes private equity as medium to long-term finance for more mature businesses, often through buy-outs or buy-ins, usually taking a large or controlling stake. Venture capital buys minority stakes in young, often pre-profit companies (BBB, private equity).

How long does a private equity investor stay in?

Typically 4 to 7 years, followed by an exit through a stock market listing, a sale to a trade buyer or a sale to another investor.

What is vendor due diligence?

Due diligence commissioned by the seller. If the deal completes, the advisers usually give the buyer, its lenders or both a duty of care so they can rely on the report.

Is financial due diligence an audit?

No. The ICAEW's guideline says financial due diligence is not an audit and gives no assurance opinion.

What is an equity ticker?

In a locked box deal, an equity ticker passes to the seller the cash profits the business makes between the locked box date and completion.
