Unfortunately, the discount to book value is because traders foresee that when rates rise the book value will fall.
Thus, the discount is an attempt to arrive at the true long term book value. Personally, I don't believe the book value will drop that much but obviously the market does.
When a company goes public, it sells only a portion of its outstanding stock. Usually, the majority of the stock is still owned by the original investors who are selling only a portion of their stock in the company. As a part of the public offering, the original stockholders agree that for a period of time after the initial public offering, they will not sell any more of their stock. This is so the stock priced is not reduced by the influx of a lot of new shares. This period is called the "lockup period" and denotes the period during which the shareholders have agreed not to sell any additional stock. The expiration of the "lockup period" means that the shareholders are once again able to sell and sometimes this means that a large amount of additional stock becomes available on the the market at one time, causing the stock price to be depressed because current supply exceeds current demand.
