The Company leases buildings for its office spaces across the globe. Lease terms typically range from 1 to 20 years and had a weighted average remaining lease term of 7.1 years at December 31, 2020 (2019 - 7.7 years). To provide operational flexibility, the Company seeks to include extension or termination options in new leases. The Company leases vehicles and office equipment with terms typically ranging from 1 to 7 years and had a weighted average remaining lease term of 2.5 years at December 31, 2020 (2019 - 2.2 years). These leases do not usually contain extension options, purchase options, or residual value guarantees. The Company also leases IT equipment and other equipment with terms typically ranging from 1 to 5 years. These leases are generally short-term or for low-value assets that the Company has elected not to recognize in lease assets and lease liabilities. As part of the Company's strategic initiative in 2020, the existing real estate lease portfolio was evaluated and resulted in the abandonment of certain leased office spaces and the approval of a formal plan to sublease the abandoned leased spaces that will no longer be utilized by the Company. A change in use related to those lease assets resulted in the recognition of impairment losses where the carrying amount of the assets exceeded the recoverable amount. The recoverable amount was determined based on the value in use method and a weighted average discount rate of 7.23%. Impairment losses and the related recoverable amounts remaining for each reportable segment are as follows:
Reportable segments | Canada | United States | Global | Total
Impairment losses |  |  |  |
Lease assets | 50.4 | 4.8 | 3.9 | 59.1
Property and equipment | 16.3 | 1.7 | 1.5 | 19.5
