Bunge provides cash advances to suppliers, primarily Brazilian farmers of soybeans and sugarcane, to finance a portion of the suppliers’ production costs. Bunge does not bear any of the costs or operational risks associated with the related growing crops. The advances are largely collateralized by future crops and physical assets of the suppliers, carry a local market interest rate, and settle when the farmer’s crop is harvested and sold. The secured advances to farmers are reported net of allowances of $1 million at September 30, 2017 and $1 million at December 31, 2016. There were no significant changes in the allowance at September 30, 2017 and December 31, 2016, respectively.

Interest earned on secured advances to suppliers of $7 million and $7 million for the three months ended September 30, 2017 and 2016, respectively, and $34 million and $25 million for the nine months ended September 30, 2017 and 2016, respectively, is included in net sales in the condensed consolidated statements of income.
