Yes. So thanks, Greg. Great question. And first off, you're right, Global Property, up this quarter, right around 20% for the year, up 39%. So obviously, we've been seeing the market opportunity in property generally. We talked in prior calls about just our general disposition. Look, I think that in practical terms, we said this over and over that we are not sort of an intentional cat writer. That includes Tier 1 cat and even some of the sort of more the unmodeled cat severe convective storm and so forth.
We absolutely have it in our book. You can't ignore that that is a component. But I think we do 2 things really well across our book, but in particular, in Global Property, is that our spread of risk is something that we are paying attention to so that we really don't have aggregations really anywhere of materiality relative to our book.
If anything, it would be maybe we have a quake exposure that aggregates for us as a company more so than maybe a Tier 1 North Atlantic kind of hurricane exposure. So that's one.
And the second thing is that our underwriting leader there has done just a terrific job in ensuring that the coverages that we're providing, the attachment points, the deductibles, all that combination of features reflects what we believe is the underlying exposure. And I think it shows through in our results where we had losses, for example, last quarter had a lot to do with, quite honestly, in one instance, the tornado dropping down on top of a roof of a large property and that was a large loss. But we -- otherwise, we've avoided things, I think, largely due to our underwriting and our approach to aggregation management.
In terms of expectations, I think, generally speaking, we'll be rerunning again here looking at our full-year portfolio. But our AALs generally run about 2% of premiums. And then if you look back and you look at our historical performance and adjust for where it is that we've grown the book and so forth, just taking like a 10-year average on that, it tends to tie about 2% of premiums as well.
And so I'd suggest to you that before sort of getting into any kind of guidance for next year and so forth, that's consistently been a reference point. It was -- I think, in general, it was the kind of number that we talked about coming into 2023. And I don't really see a great deal on our book that would suggest that that's changed greatly despite the fact that we've had some good growth in Global Property.
