Immaterial amounts for minimum lease receipts from sublet land and buildings have been netted against the minimum lease payments in this table. Minimum lease payments exclude occupancy costs and thus will differ from future amounts reported for operating lease expenses. As at December 31, 2018, commitments for occupancy costs under operating leases totalled $813 (2017 – $816).

As set out in Note 21(c), we have entered into leases with real estate joint ventures. This table includes 100% of the minimum lease payment amounts due under these leases; of the total, $46 (2017 – $109) is due to our economic interest in the real estate joint venture and $92 (2017 – $156) is due to our partners’ economic interests in the real estate joint venture.
