问题如下：
The quotes for a five-year interest rate swap are bid 3.20, ask 3.24. What swap would be entered by a company that can borrow for five years at 4.2% per year but wants to borrow at a floating rate? What rate of interest does the company end up borrowing at?
选项：
解释：
The company should arrange to receive fixed and pay floating to convert the fixed-rate loan to a floating-rate loan. It will accept the bid quote of 3.20. Its cash flows will be
• Receive 3.2%,
• Pay 4.2%, and
• Pay Libor.
These net to Libor plus 1 %.
我记得ask是卖，bid是买。
这里买swap的价格应该对应的是dealer卖的价格，应该是高的值，而不是低的值。求解惑。
而且，我看这里的现金流都是算的还款时候的现金流，为什么不用借款时的现金流呢？
