Maximum cash exposure

The most negative point on the cumulative cashflow indicates the maximum cash exposure of the project. If the project were to be abandoned at this point, this is the greatest amount of money the investor stands to lose, before taking account of specific contractual circumstances (such as penalties from customers, partner claims, contractors claims). 

The cumulative cashflow was used to derive ultimate cash surplus - the final value of the cumulative cashflow maximum exposure - the maximum value of the cash deficit payout time - the time until cumulative cashflow becomes positive. 

A vast array of alternative specifications is also possible. Practitioners often employ additional inequality constraints on portfolio weights, limiting them to maximums, minimums, or linear combinations. For example, total equity exposure may be restricted to a percentage of the portfolio or cash to a minimum required level. Another common variation is to add inequality constraints to force solutions close to benchmarks. This minimizes the risk of underperforming.
