As a limited partner, you committed $1,000 to a 10-year private equity fund. The first capital call for $700 came two years from the creation of the fund and it was completely invested in Company A. The second capital call for $300 came at time 4 and it was completely invested in Company B. Since there were no management fees, you were promised a compound 8% return on your entire investment for as long as it was invested. The portfolio companies were sold at time 10. Your share of the sales proceeds was $8,000 Your share of what had to be paid to the lenders at time 10 was $500. The agreed split of the carried interest was 25% to the GP and 75% to the LP. How much cash will you receive at time 10? What is your IRR for your total investment? After the LP has signed the LP agreement with all its details, what are the three biggest uncertainties that will affect the cash the LP will receive at time 10? Answer this in the context of the timeline we drew for the life of the fund.
