Scenario analysis for a proposed new project has resulted in the following:

NPV

Probability

Worst case

$($$$1,000)$

$\mathrm{.}2$

Most likely case

$$300$

$\mathrm{.}3$

Best case

$$600$

$\mathrm{.}5$

An abandonment option would change the NPV in the worst case to $($$$300).$ The value of the option is at least $($Answer only in integers without $ sign.$)$
