Craig Aaron, CFO, BorgWarner : I think when you think about BorgWarner and what our goal is, is drive operating income higher. So whether it's an inorganic investment or organic investment, we're always looking at return on invested capital and making sure that our operating income is growing over time because ultimately, the value of our company is is only as good as the operating income that we generate and the free cash flow that we generate. Absolutely. And so those are main metrics that we have to keep our eye on to make sure that we're fundamentally growing those metrics that we believe will drive long term shareholder value as we move forward.
