Since I have some time now, I have just updated the history of cash calls for REITs list (see here for the updated list).
The last time I updated it was in March 2017 (see here). Since then, there have been a number of additions to the list (Cromwell European REIT and Keppel-KBS US REIT).
Off the top of my head, I recall that the following REITs raised cash during this period: (a) AIMS AMP Capital Industrial REIT, (b) Cache Logistics Trust, (c) Capitaland Commercial Trust, (d) CDL Hospitality Trust, and (e) Manulife US REIT.
As always, don't take my list as it is. There might be a few cash calls that slipped my mind. Do comment if I have missed out on any.
