Ann: CIP FY22 Results Presentation, page-5

You're probably better off asking in a COF thread.

BUT i'll have a crack, the demand for office space has been severely disrupted with COVID isolation orders and a transition to WFH. Now that a fully remote or 'hybrid' work model has essentially been proven, many businesses are now looking at adopting these permanently. These changes affect the demand for office space going forward. Add to this rising inflation/interest rates/costs these tenants are looking for ways to reduce costs and probably renegotiating corporate office leases.
(I would have thought this was pretty obvious for anyone working in an office setting, the 'return to work' order has basically never returned to normal)
