Hi @jemma242 At the end of year 4 net cash flow is -$1,000. At the end of year 5 net cash flow is +$7,000. So, during year 5 Gold will collect $8,000. Gold need to collect $1,000 to have zero net cash flow after the end of year 4, and they will collect it during 1/8 of the year 5(supposing that cash flows are received evenly through the year).
