Part 1) A Private Equity firm acquires XYZ Corp., which generates $100 million in EBITDA at the time of the deal, for a 10x EBITDA purchase multiple and funds the

The companys EBITDA grows to $150 million by Year 5, but the exit multiple (valuation at which the PE sells the XYZ Corp.) drops to 9x EBITDA. XYZ Corp. repays $250 million of Debt throughout the course of the investment and generates $50 million in extra Cash by end of Year 5 as well. Calculate the IRR of the investment when the Private Equity buyer sells XYZ Corp at the end of Year 5. (Hint: Find Entry and Exit Equity Value to calculate IRR)
