Dylan Lewis: I will say, for Facebook investors, this might be a pretty solid time for them to be able to opportunistically buy shares. I know the authorization doesn't really allow them to start acting on this for a while. But you look at how they've been over the last month or so, for a company that's been a market darling for a long time, it seems like Facebook has fallen on some hard times.

Daniel Sparks: Yeah. I think that brings up why I can understand that they're actually doing this. Not only do they have the cash flow, but the timing does look good. Sure, Facebook has a P/E (price to earnings) ratio of 44X, but when you look at their forward P/E ratio, and their earnings are estimated to grow next year, that P/E ratio could get into the 20s, which, for a company growing as fast as Facebook, that's actually a pretty low P/E ratio. Then, you factor in what you might think of Facebook's competitive advantage, which, in my personal opinion, I think network effects are one of the most powerful ones, especially given Facebook's huge network effect. They have over 1 billion daily active users. I just think this is a good time for Facebook to be buying back their own stock.

Lewis: Yeah, you talked about them being at 44X as a trailing P/E right now. You go back a year, they were double that. That's not to say the company hasn't performed and the stock hasn't performed well. They are certainly up year to date over the last 12 months. I think it's just a testament to the fact that valuations creep down a little bit as the business has continued to perform, and those bottom-line numbers look pretty good for them. So, could be a good opportunity for them. And certainly, at the scale they're doing it, it won't be something that's massively disruptive, because they're in such a great financial position.
