Transfers and Servicing of Financial Assets [Abstract]
Transfers and Servicing of Financial Assets [Text Block]	SALE OF ACCOUNTS RECEIVABLE In March 2016, the Company entered into an agreement (the “Receivable Sales Agreement”), to sell, on a revolving basis, certain trade accounts receivable balances to third party financial institutions. Transfers under this agreement are accounted for as sales of receivables resulting in the receivables being de-recognized from the Consolidated Balance Sheet. The Receivable Sales Agreement provides for the continuing sale of certain receivables on a revolving basis until terminated by either party; however the maximum receivables that may be sold at any time is $700 million (increased from $550 million as of October 1, 2016). During 2016, approximately $1.5 billion of accounts receivable have been sold via this arrangement. Accounts receivable sold of $562 million remained outstanding under this arrangement as of December 31, 2016. The proceeds from these sales of receivables are included in cash from operating activities in the Consolidated Statement of Cash Flows. The recorded net loss on sale of receivables is approximately $5 million for the year ended December 31, 2016 and is included in Other income and expense. In July 2016, the Company entered into a $200 million U.S. accounts receivable securitization program with third party financial institutions. Subsequently during 2016 the program was amended to increase to its current capacity of $600 million. Under the program, we receive cash consideration of up to $600 million and a deferred purchase price asset for the remainder of the purchase price. Transfers under this agreement are accounted for as sales of receivables resulting in the receivables being de-recognized from the Consolidated Balance Sheet. This securitization program utilizes Kellogg Funding Company (Kellogg Funding), a wholly-owned subsidiary of the Company. Kellogg Funding's sole business consists of the purchase of receivables, from its parent or other subsidiary and subsequent transfer of such receivables and related assets to financial institutions. Although Kellogg Funding is included in our consolidated financial statements, it is a separate legal entity with separate creditors who will be entitled, upon its liquidation, to be satisfied out of Kellogg Funding assets prior to any assets or value in Kellogg Funding becoming available to the Company or its subsidiaries. The assets of Kellogg Funding are not available to pay creditors of the Company or its subsidiaries. This program expires in July 2017, but can be renewed with consent from the parties to the program. During the year ended December 31, 2016, $839 million of accounts receivable have been sold via the accounts receivable securitization program. As of December 31, 2016, approximately $292 million of accounts receivable sold to Kellogg Funding under the securitization program remained outstanding, for which the Company received net cash proceeds of approximately $255 million and a deferred purchase price asset of approximately $37 million. The portion of the purchase price for the receivables which is not paid in cash by the financial institutions is a deferred purchase price asset, which is paid to Kellogg Funding as payments on the receivables are collected from customers. The deferred purchase price asset represents a beneficial interest in the transferred financial assets and is recognized at fair value as part of the sale transaction. The deferred purchase price asset is included in Other current assets on the Consolidated Balance Sheet. The proceeds from these sales of receivables are included in cash from operating activities in the Consolidated Statement of Cash Flows. The recorded net loss on sale of receivables is included in Other income and expense and is not material. The Company has no retained interests in the receivables sold under the programs above, however the Company does have collection and administrative responsibilities for the sold receivables. The Company has not recorded any servicing assets or liabilities as of December 31, 2016 for these agreements as the fair value of these servicing arrangements as well as the fees earned were not material to the financial statements. Additionally, from time to time certain of the Company's foreign subsidiaries will transfer, without recourse, accounts receivable balances of certain customers to financial institutions. These transactions are accounted for as sales of the receivables resulting in the receivables being de-recognized from the Consolidated Balance Sheet. During the year ended December 31, 2016, $164 million of accounts receivable have been sold via these programs. Accounts receivable sold of $124 million remained outstanding under these programs as of December 31, 2016. The proceeds from these sales of receivables are included in cash from operating activities in the Consolidated Statement of Cash Flows. The recorded net loss on the sale of these receivables is included in Other income and expense and is not material.
