US logistics company FedEx has "permanently retired" 15 aircraft and 21 related engines as it continues to "rationalise capacity and modernise its aircraft fleet to more effectively serve FedEx Express customers," a spokesperson has said.
In May 2015, FedEx accepted a non-cash impairment charge of US$246m and has also made amendments to the retirement schedule of an additional 23 airframes and 57 engines, with an associated US$30m in cash charges.
In April, the company bid US$4.8bn to acquire rival operator TNT Express, culminating in a mutual conditional agreement, expected to receive regulatory approval in early 2016.
In a short statement on its investors' website, FedEx said: "These combined retirement changes will not have a material impact on near-term depreciation expense."
