Just, just an quick final comment there, this is probably the most challenging question that we're faced as a company today, we've got a number of very, very promising products and market share opportunities and we don’t want to, we don't want to blow this opportunity. So, this long term versus short-term, are we cutting too much, are we too lean and are we short cutting great opportunities is one that we wrestle with all the time, we think we've made the right judgments here, we're committed to and said publicly that we need to be more short-term this year to drive cash flow, at the same time, you can fetch your bottom dollar that every, every moment that we think about this cost control stuff, we know we have huge revenue opportunities and we are asking ourselves, are being too short-term and are we spending enough. So I think the trick here is to be flexible and to keep checking, checking, checking, and being as realistic as we can with respect to what our future benefits and candidly here we're being, we are taking down revenue and we don't like doing that, but I think we realistically need to do that if and we are going to play in on that, but at the same time, if we see an uptick here, it will be, it will be a surprise to us as well as to our investors, it will be a pleasant surprise and we will be ready to pounce on that business with an expansion of the, expenses to support that as necessary. So its where we're right now as a company, drive cash flow, but keep that revenue engine going and really position ourselves for an expansion and enjoy some of the margins that Cathy has been talking about.
