While we are not able to report financial results at this time, our overall performance for the first three quarters of the year has enabled us to reaffirm our adjusted annual guidance for 2016.

Mr. Thompson continued, The company s new order and option activity in the third quarter exceeded $2.0 billion and, together with additional bookings in October, boosted year-to-date totals to over $7.5 billion. In addition, we remained committed to our capital deployment strategy by returning approximately $60 million in the third quarter and about $170 million so far this year to stockholders in share repurchases and dividends.

Disclosure and Reconciliation of Non-GAAP Financial Measures

We define free cash flow as cash from operating activities less capital expenditures. Management believes that the company s presentation of free cash flow is useful because it provides investors with an important perspective on the company s liquidity, financial flexibility and ability to fund operations and service debt.

Adjusted measures are provided so investors can more easily compare current and prior period results of the combined companies. These adjusted results should not be considered in isolation or as a substitute for the related GAAP measures, and other companies may define such measures differently. We encourage investors to view our non-GAAP measures with our GAAP financial results and not to rely on any single financial measure. The reconciliation of GAAP results to adjusted non-GAAP results is as follows:
