Desh Fashion is a Bangladeshi garment factory producing clothes for men, women, and children for European and American retailers. Over the last few years, it has made a substantial amount of profit as the demand for fast fashion has been significantly increasing among young people, in particular. However, recently the company is facing some uncertainties because of the trade war between China and America in addition to Brexit related tensions. Desh Fashion is losing its profitability since the beginning of 2018. To minimise the uncertainties it is facing and secure profit, Desh Fashion has decided to introduce its product to the Asian market, mainly in China.

To pursue the companys dream, the Managing Director (MD) is considering acquiring a few local factories that produce fast fashion for the local market. The top-management approves the decision and prepares a proforma financial statement for the next five years. In the following table, the first three years expected revenues and their probabilities are presented.

Year	Revenue (, 000)	Probability
2021	520	40%
