The Big 4 and Top 10 firms usually have specialist valuation teams that carry out complex valuations of businesses in order to advise on the feasibility of specific deals. In smaller firms, this work is usually absorbed by the general corporate finance team.

Working closely with lead advisors, and transaction services, business valuations are undertaken by employing methods such as discounted cash-flow (e.g. NPV, IRR), P/E ratios and comparison with industry standards, cost of capital analysis, and other types of complex financial modelling.
