Financing Receivables [Text Block]	RECEIVABLES AND FINANCING ARRANGEMENTS Receivables. The Company's accounts receivable, net primarily consists of amounts due from Credit Receivables (defined below), department store operators that host TIFFANY & CO. boutiques in their stores, third-party credit card issuers and wholesale customers. The Company maintains an allowance for doubtful accounts for estimated losses associated with the accounts receivable recorded on the balance sheet. The allowance is determined based on a combination of factors including, but not limited to, the length of time that the receivables are past due, management's knowledge of the customer, economic and market conditions and historical write-off experiences. For the receivables associated with Tiffany & Co. credit cards ("Credit Card Receivables"), management uses various indicators to determine whether to extend credit to customers and the amount of credit. Such indicators include reviewing prior experience with the customer, including sales and collection history, and using applicants' credit reports and scores provided by credit rating agencies. Certain customers may be granted payment terms which permit purchases above a minimum amount to be paid for in equal monthly installments over a period not to exceed 12 months (together with Credit Card Receivables, "Credit Receivables"). Credit Receivables require minimum balance payments. An account is classified as overdue if a minimum balance payment has not been received within the allotted timeframe (generally 30 days), after which internal collection efforts commence. For all Credit Receivables recorded on the balance sheet, once all internal collection efforts have been exhausted and management has reviewed the account, the account balance is written off and may be sent for external collection or legal action. At April 30, 2016 and 2015, the carrying amount of the Credit Receivables (recorded in accounts receivable, net) was $80.9 million and $68.0 million, of which 97% was considered current in both periods. The allowance for doubtful accounts for estimated losses associated with the Credit Receivables (approximately $1.4 million at April 30, 2016 and $1.0 million at April 30, 2015) was determined based on the factors discussed above. Finance charges earned on Credit Card Receivables are not significant. Financing Arrangements. The Company has provided financing to diamond mining and exploration companies in order to obtain rights to purchase the mine's output (see "Note 10. Commitments and Contingencies"). Management evaluates these financing arrangements for potential impairment by reviewing the parties' financial statements along with projections and business, operational and other economic factors on a periodic basis. At April 30, 2016 and 2015, the current portion of the carrying amount of financing arrangements including accrued interest was $2.5 million and $21.0 million and was recorded in prepaid expenses and other current assets. At April 30, 2016 and 2015, the non-current portion of the net carrying amount of financing arrangements including accrued interest was $19.9 million and $41.3 million and was included in other assets, net. As of April 30, 2016, the Company had a $43.8 million loan receivable under a financing arrangement (the "Loan") with Koidu Limited (previously Koidu Holdings S.A.) ("Koidu"). The Company recorded impairment charges totaling $37.9 million during the fiscal year ended January 31, 2016 related to the Loan, and the net carrying amount of the Loan was $5.9 million as of April 30, 2016. The Company intends to continue to participate in discussions with Koidu and certain of Koidu's stakeholders as part of management's ongoing evaluation of the collectability of the Loan and the accrual of interest income. See "Note 10. Commitments and Contingencies" for additional information on this financing arrangement. Management has not recorded any impairment charges on such loans in the three months ended April 30, 2016 and 2015.
