The largest lessees of our managed fleet are responsible for a significant portion of the billings that generate our management fee revenue.

Container Management Segment Concentration. A substantial majority of the Company's container management segment revenue is derived from container investors associated with five different investment arrangers located in Germany, Switzerland, Austria and Japan. These arrangers are typically in the business of identifying and organizing investors for a variety of investment vehicles and compete with other institutions in these and other countries that perform similar functions.
