This is the errata for the second printing of second edition of Concepts.
CUP unfortunately reintroduced a lot of errors that had previously been fixed.

"The expectation of the square of Rn will be equal to minus the expectation of Rn since the pay-off is zero or minus one."

"We
can use no-arbitrage to deduce the price of any option with a
(measurable) compactly supported pay-off, $f$ -- i.e. a payoff which is zero outside a
