Before revision:  In such a setting we obtain a sublinear pricing measure for additional contracts  . Similar to the forward measure approach, we define a forward sublinear expectation to simplify the valuation of cashflows.
After revision:  In such a setting we obtain a sublinear pricing measure for additional contracts , which yields either a single price or a range of prices . Similar to the forward measure approach, we define a forward sublinear expectation to simplify the valuation of cashflows.
