The restructuring charges relate to Equinix's decision to exit leases for excess space adjacent to several of its IBX ® data centers, which it did not intend to build out, or its decision to reverse such restructuring charges. Equinix also excludes impairment charges generally related to certain long-lived assets. The impairment charges are related to expense recognized whenever events or changes in circumstances indicate that the carrying amount of assets are not recoverable.
