单选题 Sue Wilkins buys one corn futures contract at $3.00 per bushel (one contract is for 5000 bushels). The initial margin requirement is 10 percent of the total contract purchase price, and the maintenance margin level is 65 percent. What is the amount of the per bushel price decline that will require a maintenance margin call to Wilkins?

A、

A. $0.1250.
B、

B. $0.675.
C、

C. $0.1050.

【正确答案】 C

【答案解析】The initial margin requirement is ( $3.00 × 5000 × 0.10) = $1500.00. The maintenance margin level is ( $1500 × 0.65 ) = $975.00. The difference between the initial and maintenance margin amounts is ( $1500.00 - $975.00) = $525.00. When the market value of the commodity decreases, the daily settlement process reduces the amount in the trader's margin account. When the initial level of margin declines by $525.00 Wilkins will receive a maintenance margin call. This will occur when the price per bushel declines by: ( $525.00/5000) = 0.105, or by $0.1050.
