If you are not familiar with the Decision Tree concept, please refer to Appendix B [Modeling Uncertain Cash Flows Using Net Present Value Analysis) of our textbook It is reported that the construction union contract expires at the end of the 4811' week. Hence there might be a union strike at the end of 48m week with 50 '36 chance. Based on past 10 year history, if the strike occurs, it usually takes 5 weeks with 70 96 or 7 weeks with 30 '36 Chance.
