The following table presents the selected combined and consolidated financial data, which should be read in conjunction with our combined and consolidated financial statements and related notes and Management's Discussion and Analysis of Financial Condition and Results of Operations included elsewhere in this Form 10-K. We derived the selected financial data as of October 31, 2015 and for each of the fiscal years in the three-year period ended October 31, 2015 from our audited combined and consolidated financial statements included elsewhere in this Form 10-K. We derived the selected financial data as of October 31, 2012 and for the fiscal year ended October 31, 2011 from audited combined financial statements that are not included in this Form 10-K.

Our historical combined and consolidated financial statements include certain expenses of Agilent that were allocated to us for certain functions, including general corporate expenses related to information technology, research and development, finance, legal, insurance, compliance and human resources activities. These costs may not be representative of the future costs we will incur as an independent public company. The historical financial information included here may not necessarily reflect our financial position and results of operations or what our financial position and results of operations would have been had we been an independent, publicly-traded company during the historical periods presented or be indicative of our future performance as an independent company.
