Growth Capital Case Study - HELP!

All,

I am currently faced with a rather perplexing (out of comfort zone) PE (growth capital) case study and would be HUGELY grateful of any suggestions:

- Opportunity: Opportunity to invest up to £200m as part of a £1bn syndicate (with £800m already committed by other members) into a growing tech/manufacturing company. No talk of share classes or ranking.

- Nuances: No balance sheet is presented, just P&L and cash flow statements. The £1bn equity round is for growth capital, and buys a minority stake in the business (stake not disclosed, however original partners stated as retaining majority).

- Leverage: The business plan states that management intend to raise circa £1.1bn of mezz and senior debt the year after the equity raise.

Aside from various industry information, this is the core of the task. How would anyone go about evaluating such a deal? What leverage opportunities exist for a growth capital investor and what structure might work in this case?

Is it possible to ascertain security without a balance sheet?

Many thanks for any swift responses!
