The multiplier for a futures contract on the stock$-$market index is $$250.$ The maturity of the contract is one year, the current level of the index is $700,$ and the risk$-$free interest rate is $0\mathrm{.}4\%$ per month. The dividend yield on the index is $0\mathrm{.}2\%$ per month. Suppose that after one month, the stock index is at $719.$

a$.$ Find the cash flow from the mark$-$to$-$market proceeds on the contract. Assume that the parity condition always holds exactly. $($Do not round intermediate calculations. Round your answer to $2$ decimal places.$)$

Cash flow $

b$.$ Find the one$-$month holding$-$period return if the initial margin on the contract is $$20,000.($Do not round intermediate calculations. Round your answer to $2$ decimal places.$)$
