Okay. So specifically, with the gross profit margin, our purchasing cost reduction program, as we mentioned, has been in place since the middle of 2006. We continue to experience strong favorable PPV with respect to that program, and we expect that going forward as well. When you look at the gross profit margin in the quarter improving on a sequential basis or versus our guidance, that really was, to some degree, a function of product mix that helped with that upward trend, as well as ongoing manufacturing cost efficiencies, as some of the cost reductions and efficiencies came in a little bit better than our beginning-of-the-quarter forecast. So we anticipate that we will continue to benefit from the manufacturing cost reductions. The product mix will certainly be dependent on customer orders, but we do also anticipate ongoing purchasing cost reduction efforts. Specifically with ER&D, as we look, and we've discussed previously, the Q1 and Q2 of last year were really at peak levels of R&D spends on a year-over-year basis, and the reduction, the primary driver there, is the result of cost savings associated with contract engineering and development services. And if you recall, we started to transition in the third quarter of last year where, in some instances, we started to convert some of the contract engineers to permanent hires that resulted in reduced overall cost to the company. There are also situations in which a particular contract engineer met certain project milestones and their particular skill sets were no longer needed. And so that started in Q3 of '12, continued through Q4 of '12, and that is pretty much now complete in the first part of Q1 of '13. So we're not anticipating any further reductions or shifts and changes in the trend with respect to contract engineers as we've kind of worked our way through them. Specifically with SG&A expenses, Q2 of last year was really the peak of the spend within SG&A. When we look on a sequential basis, SG&A expenses came down, primarily on the overseas office expense area, and it did come in a little bit lower than our initial forecast. And that really is an effort overall, with some of the efficiencies we're starting to see with the resources we devoted last year and some of our cost management initiatives within the company. As with ER&D and SG&A, we continue to have open positions of specific skill sets, and those are difficult positions to find those specific skill sets. So obviously, the timing of those adds can differ from our forecast, depending on how that process progresses and how quickly we can find those individuals.
David Leiker - Robert W. Baird & Co. Incorporated, Research Division: Such that, it'd be fair to say that sequentially, there's still room over time on the gross margin side, and then on the operating expense, sequentially, you may be more stable, but there's still a couple of quarters of year-over-year performance?
