Yes. Of our 20 properties, 10 are over 30 years old and coming to what is known as the end of their operating agreements, which in our case is 35 years. We have some housing that isn't ready for redevelopment. That's the sort of logical next step after the operating agreements expire, so we have to keep those buildings up. Through processes such as replacement reserve, modernization and improvement, and other tools, we do try to do that on a regular basis. However, every year that costs more and more money, and even though replacement reserve might have been regarded as adequate 30 years ago, the amount that we put in turns out to be not so, as everything is so much more expensive.
For example, I can think of three buildings that we have now that are going through capital refunding to the tune of $4 million and $5 million for each property. This is an ongoing example, separate and distinct from redevelopment or acquisition of new housing, which we also actively chase.
