Good afternoon, and thank you for joining us on Celestica's Fourth Quarter 2019 Earnings Conference Call. On the call today are Rob Mionis, President and Chief Executive Officer; and Mandeep Chawla, Chief Financial Officer.
As a reminder, during this call, we will make forward-looking statements within the meanings of the U.S. Private Securities Litigation Reform Act of 1995 and applicable Canadian securities laws. Such forward-looking statements are based on management's current expectations, forecasts and assumptions, which are subject to risks, uncertainties and other factors that could cause actual outcomes and results to differ materially from conclusions, forecasts or projections expressed in such statements. For identification and discussion of such factors and assumptions as well as further information concerning financial guidance, please refer to today's press release, including the cautionary note regarding forward-looking statements therein, and our annual report on Form 20-F and other public filings, which can be accessed at sec.gov and sedar.com. We assume no obligation to update any forward-looking statement, except as required by law.
In addition, during this call, we will refer to various non-IFRS measures, including operating earnings, operating margin, adjusted gross margin, adjusted return on invested capital or adjusted ROIC, free cash flow, gross debt to non-IFRS trailing 12-month adjusted EBITDA leverage ratio, adjusted net earnings, adjusted EPS, adjusted SG&A expense and adjusted effective tax rate. Listeners should be cautioned that the references to any of the foregoing measures during the call denote non-IFRS measures, whether or not specifically designated as such. These non-IFRS measures do not have any standardized meanings prescribed by IFRS and may not be comparable to similar measures presented by other public companies that use IFRS or who report under U.S. GAAP and use non-GAAP measures to describe similar operating metrics. We refer you to today's press release and our fourth quarter earnings presentation, which are available at celestica.com under the investor relation tab, for more information about these and certain other non-IFRS measures, including a reconciliation of historical non-IFRS measures to the most directly comparable IFRS measures from our financial statements. Unless otherwise specified, all references to dollars on this call are to U.S. dollars.
Let me now turn the call over to Rob.
