The leading six North American operators have between US$3 billion and US$7 billion of cash unnecessarily tied up in WC processes.
For North American operators, there was a further improvement in WC performance in 2010 relative to 2009. The net trade WC to sales ratio fell from 1.1% to 0.3%, with C2C dropping by 14% over that period.
WC progress in 2010 was due to lower levels of receivables and, to a lesser extent, higher levels of payables. Levels of deferred income increased from 3.8% to 3.9% of sales, while inventory performance deteriorated.
Overall, five companies out of six reported a year-on-year improvement in WC performance.

Opportunity for improvement
Variations in WC performance between operators in North America point to significant potential for improvement.
A high-level analysis suggests that the leading six North American operators have between US$3 billion and US$7 billion of cash unnecessarily tied up in WC processes, equivalent to between 0.8% and 2.2% of sales.
Analysis shows that the cash opportunity comes primarily from payables (three-quarters of total), with the rest evenly split between receivables and inventories.
