Organization and Basis of Presentation	Organization and Basis of Presentation Ingram Micro Inc. and its subsidiaries are primarily engaged in the distribution of information technology (“IT”) products, commerce and fulfillment services and mobile device lifecycle services worldwide. Ingram Micro Inc. and its subsidiaries operate in North America; Europe; Asia-Pacific (which includes Middle East and Africa); and Latin America. The consolidated financial statements include the accounts of Ingram Micro Inc. and its subsidiaries. Unless the context otherwise requires, the use of the terms “Ingram Micro,” “we,” “us” and “our” in these notes to the consolidated financial statements refers to Ingram Micro Inc. and its subsidiaries. These consolidated financial statements have been prepared by us, without audit, pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). In the opinion of management, the accompanying unaudited consolidated financial statements contain all material adjustments (consisting of only normal, recurring adjustments) necessary to fairly state our consolidated financial position as of October 3, 2015, our consolidated results of operations and comprehensive income for the thirteen and thirty-nine weeks ended October 3, 2015 and September 27, 2014 and our consolidated cash flows for the thirty-nine weeks ended October 3, 2015 and September 27, 2014. All significant intercompany accounts and transactions have been eliminated in consolidation. As permitted under the applicable rules and regulations of the SEC, these consolidated financial statements do not include all disclosures and footnotes normally included with annual consolidated financial statements and, accordingly, should be read in conjunction with the consolidated financial statements and the notes thereto, included in our Annual Report on Form 10-K filed with the SEC for the year ended January 3, 2015. The consolidated results of operations for the thirteen and thirty-nine weeks ended October 3, 2015 may not be indicative of the consolidated results of operations that can be expected for the full year. Book Overdrafts Book overdrafts of $329,498 and $400,323 as of October 3, 2015 and January 3, 2015, respectively, represent checks issued on disbursement bank accounts but not yet paid by such banks. These amounts are classified as accounts payable in our consolidated balance sheet. We typically fund these overdrafts through normal collections of funds or transfers from other bank balances at other financial institutions. Under the terms of our facilities with the banks, the respective financial institutions are not legally obligated to honor the book overdraft balances as of October 3, 2015 and January 3, 2015, or any balance on any given date. Trade Accounts Receivable Factoring Programs We have several uncommitted factoring programs under which trade accounts receivable of several large customers may be sold, without recourse, to financial institutions. Available capacity under these programs is dependent on the amount of trade accounts receivable already sold into these programs and the financial institutions’ willingness to purchase such receivables. At October 3, 2015 and January 3, 2015, we had a total of $293,097, and $276,808, respectively, of trade accounts receivable sold to and held by financial institutions under these programs. Factoring fees of $947 and $1,058 incurred for the thirteen weeks ended October 3, 2015 and September 27, 2014, respectively, and $3,263 and $3,276 incurred for the thirty-nine weeks ended October 3, 2015 and September 27, 2014, respectively, related to the sale of trade accounts receivable under these facilities are included in “other” in the other expense (income) section of our consolidated statement of income. Impairment of Internally Developed Software We began our program to deploy a new global ERP system seven years ago. Over that period, the business has significantly diversified and new technologies allow legacy systems and diverse applications to easily be connected in a modular way, which allows these legacy systems to be part of a flexible, powerful and efficient solution. After careful evaluation, we have concluded that this combined systems strategy is better aligned with our evolving business model and is more flexible and economical than a single global system. Accordingly, we have stopped our global ERP deployment and recorded a non-cash, pre-tax charge related to the impairment of internally developed software of $115,856 during the second quarter of 2015. We recognized a tax benefit on the impairment at the applicable rates, partially offset by an increase in the valuation allowance on foreign tax credits of $14,580 as a result of the decision to stop deployments.
