The affected debt of Canon, is some $1,700m in yen and $760m – and it is rated A2. Moody’s review will focus on Canon’s ability to improve its competitiveness in the rapidly changing global business machine market by developing new products and technologies that meet the needs of its customers, especially ones that provide digital networking capabilities for the office.
