Rich, thank you very much. Pretty attractive picture. And even a conservative CPA couldn't make it sound anything other than encouraging.
So a couple of observations on my end. Obviously, the topline growth, we're pleased with the progress that we're making relative to the past few quarters. I think this is unfolding exactly as we suggested. Just calling out a few pieces of that puzzle. Clearly some of the things that we had talked about as far as portfolios that we were separating from, much of that pig is through the python. The specialty market, in general, continues to be particularly attractive. I would highlight E&S especially. Furthermore, I don't think that party is over. When we're looking at the submission flow, we continue to be quite encouraged. On the other hand, certainly, within the professional liability space and I'll call out public D&O as perhaps one of this extreme examples, I think it is a delicate and treacherous and as you can see in the numbers in our release, we are treading thoughtfully as you'd expect.
Rich touched on the rate coming in at 8%, which, based on our assessment, is pretty clear that we are comfortably exceeding any reasonable assumption around loss cost trend. And we are encouraged by that. I know that there are couple of Chicken Littles out there that are sort of hanging on the rate number that we share on a quarterly basis and some might say, well, geez, this is down below where it was in the third quarter. And that is a factually correct statement. That having been said, I would caution people to please understand, that has really driven by mix of business and not just product line, but we have more than 60 different businesses under the Group umbrella and at any moment in time, some are growing more than others and rate opportunity is not equal amongst all the businesses in the Group, and obviously our product lines as well.
And just as a point of reference, you'll recall this time or fourth quarter '22, we got 6.9 points of rate ex-comp. So, again, we are comfortably above where we were a year ago and we are confident again that we are exceeding trend by a meaningful margin.
Again, Richie talked about the losses. I'm not going to get into that. The only thing that I will flag is that the paid loss ratio for the quarter came in at 48 and change. And for -- I don't know how many quarters it is at this stage, it's just sort of floating between 46 and 49, which I think is really just a reflection of the rate action along with the underwriting discipline and focus of our colleagues that are allowing us to be arguably writing business at a pretty healthy margin, to say the least.
Again, Rich touched on the expense piece. So I'm not going to rehash that other than I will make the one comment that, for purposes of '24, we have some businesses that we started prior. And those are going to be impacting our expense ratio. Even with those coming into the expense ratio as they are in business for a full year, the fact of the matter is, that's going to be a relatively modest drag. Going the other way, as far as benefit goes, you can see what happened with our written premium in Q3 and certainly in Q4, and we all know how that's going to trickle through and impact the earned in '24, which will clearly be a positive.
Last comment on the investment portfolio. Rich touched on that. As far as the book yield, as far as we're concerned, the new money rate for us still today, even with all the humming and hawing about where interest rates are going, we still can put money to work at 5%-plus. So we think that there's opportunity there. As Rich mentioned, the duration, 2.4 years. We are looking for the window of opportunity to nudge that out. We are not in a rush. We have a slightly different view than much of the world as to where interest rates are going. And when the window of opportunity presents itself, you will likely see that 2.4 years moving out from here.
So, again, I think it's exciting that we had a good quarter. It's rewarding and encouraging that we had a good year and top of a -- a good year in '22 and so on. But I think the most encouraging thing is, when you look at where -- how I should say, how the table is set for '24 and beyond, we are in a very good place and not only on the underwriting side, but on the investment side. So I believe in '24 and likely beyond, you are going to continue to see this economic model firing on all cylinders.
So that probably wasn't as brief as I promised, but it was relatively brief for me. And I'm going to pause there. And, Sarah, we would be very pleased to open it up for questions. Thank you.
