Significant Group Concentrations of Risk

Credit Risk

Financial instruments involving potential credit risk are predominantly with commercial aircraft customers and the U.S. government. Of the $13,639 in gross accounts receivable and gross customer financing included in the Consolidated Statements of Financial Position as of December 31, 2017, $5,572 related predominantly to commercial aircraft customers ($2,512 of accounts receivable and $3,060 of customer financing) and $5,989 related to the U.S. government.

Of the $3,061 in gross customer financing, $1,828 related to customers we believe have less than investment-grade credit including Silk Way, American, and Hawaiian Airlines who were associated with 14%, 8%, and 7%, respectively, of our financing portfolio. Financing for aircraft is collateralized by security in the related asset and in some instances security in other assets as well.

Other Risk

As of December 31, 2017, approximately 37% of our total workforce was represented by collective bargaining agreements.
