Iron Mountain Incorporated (IMI) provides information protection and storage services. These services can be divided into three service categories: records management services, data protection and recovery services, and information destruction services. The Company offers both physical services and technology solutions in each of these categories. Media formats can be divided into physical and electronic records. Physical records include paper documents, as well as all other non-electronic media such as microfilm and microfiche, master audio and videotapes, film, X-rays and blueprints. Electronic records include email and various forms of magnetic media such as computer tapes and hard drives and optical disks. IMI derives most of its revenues from the storage of paper documents and storage-related services. In May 2008, the Company acquired the DocuVault, a provider of records storage, secure shredding and data backup services in Denver and Colorado Springs.
