Good day tutor, Are we still required to perform calculations to find the equity value of a firm using the BSOP model? This was last tested in June 2010 before the current examiner took over, although there was a simple theory question on it as well in June 2014. If so, is this article still fully relevant? It's called "Application of option to valuation of firms". I only managed to find this using google search, this was never listed on the official technical articles section in P4. Here is the link to it: https://www.accaglobal.com/sg/en/student/exam-support-resources/professional-exams-study-resources/p4/technical-articles/application-of-option-pricing-to-valuation-of-firms.html . This is one hard article to understand!
