Andrew C. Wiechmann
Chief Financial Officer at MSCI
Thanks, Baer, and hi, everyone. Our attractive financial model enabled us to deliver double-digit growth in the quarter across revenue, recurring subscription run rate, and adjusted EPS. In index subscription, we drove 9% run rate growth in our market cap weighted modules, high-teens growth in custom indexes, and mid-teens growth in our ESG and factor modules.
We saw strong subscription run rate growth from hedge funds, wealth managers and broker dealers of 26%, 19% and 15%, respectively, all of which continue to support steady double-digit index subscription run rate growth. Asset-based fee revenues were up more than 12% year over year, benefiting from $55 billion of cash inflows and $186 billion of market appreciation over the last 12 months within equity ETFs linked to MSCI indexes.
During the third quarter, cash inflows into ETFs linked to MSCI equity indexes were driven almost entirely by ETFs with U.S. and other developed market exposures. These cash inflows were supported by roughly $3 billion of flows into equity ETFs linked to our ESG and Climate indexes, and we continue to gain traction in fixed income, with AUM and ETFs linked to MSCI and Bloomberg joint fixed Income indexes reaching nearly $52 billion, growing more than 40% year over year.
In Analytics, subscription run rate growth was 7%, with continued strength in our factor models and our risk tools more broadly. Our investments in enhancing our content, our capabilities, and the client experience, including through Climate Lab Enterprise Insights and ESG and Climate Reporting Services, are driving new commercial opportunities across analytics.
In our ESG and Climate reportable segment, the run rate growth was 25%, with 21% growth in ESG Research and 44% growth in Climate. Relative to a year ago, we saw lower new recurring sales in the Americas, which continue to reflect more measured purchasing decisions among U.S. investors. However, new recurring sales in both Europe and APAC were essentially unchanged year over year. The retention rate in ESG and Climate segment remained healthy at 96%, although we did see slightly higher cancels resulting from client events at smaller institutions.
Within real assets, run rate growth was 10%. We see momentum in our real estate index intel and portfolio offerings, although we continue to see the impact of industry pressures on our transaction data, most notably in client segments such as real estate brokers and lenders. While we expect the pressures to continue, we are encouraged by the long-term opportunity and the momentum we see in many of the market data, climate and portfolio offerings we are providing.
We are also expanding our commercial real estate transaction database to include deals below $2.5 million, and our data universe to include properties that have never transacted. As a reminder, beginning in the fourth quarter, we will report financial results for Burgiss in our All Other-Private Assets segment. To provide an update on the financial impact of Burgiss, we expect Burgiss to generate slightly above $90 million of revenue for full year 2023, with revenues of $22 million to $24 million expected in the fourth quarter.
The standalone Burgiss adjusted EBITDA margin is expected to be around 15% for full year 2023. However, we currently expect about $4 million to $5 million per quarter of allocations to Burgiss from centralized and shared costs on top of the standalone adjusted EBITDA. It is worth noting that these allocations are reallocated from other segments and will not impact firmwide EBITDA. Given these allocations, we expect contributions from Burgiss to the adjusted EBITDA for the All Other segment to be minimal in Q4, although we expect some margin expansion from Burgiss next year. Meanwhile, as we've done in previous acquisitions, we will exclude certain integration-related expenses from our adjusted non-GAAP figures.
More broadly, on the capital allocation front, we continued to be opportunistic and capitalized on attractive opportunities, as highlighted by our announced acquisition of Trove. We expect Trove, which has a few million dollars of run rate and which will be included in our ESG and Climate segment, to be immaterial to our results in the near term.
Turning to our guidance. I would highlight that our ranges incorporate the impact of Burgess and assume that AUM levels remain relatively stable through the balance of the year. Expense ranges now reflect both a slightly elevated pace of spend as well as a full quarter of expenses from Burgiss, including a small amount of integration expenses that will not be excluded from adjusted metrics.
Our free cash flow guidance remains unchanged, although we have slightly increased our capex guidance, which continues to reflect a higher level of software capitalization and some elevated hardware purchases related to our hybrid infrastructure approach, which includes maintaining a presence in select on-prem data centers in addition to leveraging our public cloud partnerships.
Our D&A guidance captures the additional intangible amortization from purchase accounting adjustments related to the acquisitions. We've slightly lowered and narrowed our effective tax rate guidance, reflecting the impact of a non-taxable gain on our investment in Burgiss of approximately $140 million in the fourth quarter, which will be excluded from our adjusted metrics. Excluding the impact of this one-time item, we would expect an adjusted tax rate range for the full year that is about 1% higher than the effective tax rate range or 17.5% to 19%. Lastly, our interest expense guidance reflects our intention to draw a small amount on the revolver to provide some additional liquidity.
Additionally, I would highlight that we expect lower interest income on our cash balances as a result of funding purchase. As of today, we currently have more than $300 million of cash on hand, which is in line with our minimum global cash balance range. Overall, we remain well positioned to drive growth. While we continue to see some budget pressures from clients and a slightly elevated level of client events, we continue to see healthy engagement from our clients and a strong pipeline to finish out 2023. We look forward to keeping you posted on our progress.
And with that, operator, please open the line for questions.
