1，To wit: Late Tuesday afternoon, just when every other working stiff was headed out to the beach or a barbeque for Wednesday's July 4th holiday, two jaw-dropping deals crossed the tape within minutes of each other, one from Kravis, the other from Schwarzman.
其中的two jaw-dropping deals crossed the tape应如何翻译？
2，KKR did so without a proper amount of due diligence.
其中的amount of due diligence应如何翻译？
谢谢指教！
