单选题 Which of the following statements regarding the mark to market of a futures account is FALSE? Marking to market of a futures account:

A、 may result in a margin balance above the initial margin amount and may be done more often than daily.
B、 is only done when the settlement price is below the maintenance price.
C、 effectively adjusts the price of the future to the new equilibrium level.

【正确答案】 B

【答案解析】Futures accounts are marked to market daily based on the new settlement price, which can result in either an addition to or subtraction from the previous margin balance. Under extraordinary circumstances (volatility) the mark to market can be required more frequently. Once the margin is marked to market, the contract is effectively a futures contract at the new settlement price.
