Note 4 – Accounts Receivable

Financial instruments that potentially subject us to concentrations of market or credit risk consist principally of trade receivables. While our trade receivables are diverse and represent a number of entities and geographic regions, the majority are with the U.S. government and its contractors and entities in the aviation industry. The composition of our accounts receivable is as follows:

	November 30,		May 31,
	2019		2019
U.S. Government contracts:
Trade receivables	$	32.7	$	28.7
Unbilled receivables		29.8		31.7
		62.5		60.4
All other customers:
Trade receivables		99.8		92.5
Unbilled receivables		46.2		44.9
		146.0		137.4
	$	208.5	$	197.8

In addition, we currently have past due receivables owed by former commercial program customers primarily related to our exit from customer contracts in certain geographies, including Colombia, Peru, and Poland. Our past due receivables owed by these customers was $10.1 million as of November 30, 2019, which was net of allowance for doubtful accounts of $6.2 million.
