【求助】关于配股的cost

•Rightsoffering has downsides compared to underwriting:

–If the right is exercised, youbuy more exposure to stock

–If you sell the rights, incur taxliability (in the US)

–Underwriting will increaseawareness through the “road shows”

–Suffer larger price drops thancash offers.

请问这四点该怎样理解呢？谢谢！
