Andy Wiechmann
Chief Financial Officer at MSCI
Thanks, Baer and hi, everyone. As Henry mentioned, we completed 2022 by delivering organic subscription revenue growth nearly 16% for the quarter and 15% for the full-year, outperforming our long-term target of low double-digit growth. In the face of market headwinds, our results reflect the durability of our franchise and the benefits of the consistent investments we've made into attractive high-growth areas.
In Index, subscription run rate growth was 12% in the quarter, our 36th consecutive quarter of double-digit growth. We've seen tremendous traction and healthy growth within our market cap-weighted modules, as our buy-side clients broaden their usage of our indexes and we continue to see the utility of our index content expand across a wide range of high-growth segments.
Across our Index subscription base, asset managers and asset owners together had subscription run rate growth of 10%, while hedge funds, broker-dealers and wealth managers together grew 17%. We also saw continued momentum in our investment thesis index offerings with non-market cap index modules collectively achieving a subscription run rate growth of 14%.
From the end of September through year-end, market appreciation contributed approximately $119 billion to AUM balances of equity ETFs linked to MSCI indexes. Although for the full year, we saw a net decline of $284 billion in AUM balances. Additionally, we were encouraged by the $23 billion of cash inflows into ETFs linked to our equity indexes during the quarter with roughly $15 billion of inflows into emerging market exposures and over $9 billion into developed market exposures.
Equity ETFs linked to MSCI ESG and climate indexes experienced inflows of $6.5 billion, representing approximately 70% market share. Flows into ETFs linked to MSCI factor indexes were more muted, but still positive with investor appetite more focused on yield and income where we have less presence than on other factors where indexes are more widely used, such as momentum and minimum volatility.
During the fourth quarter, the run rate basis points on AUM paid to us by ETF clients was flat year-over-year supported by a mix shift out of lower fee products. Despite the steady levels over the last year, we continue to believe the average basis points on AUM paid to us by ETF clients will gradually decline overtime, although we expect the declines will be more than offset by strong growth in assets.
In listed futures and options, we once again saw some of the natural hedges embedded in our asset-based fee revenue line, as traded volumes showed healthy growth against the choppy market backdrop. Looking ahead, if market levels continue to rebound and stabilize, we would hope this would be constructive to AUM-linked revenues from ETFs and non-ETF passive.
At the same time, futures and options volume and revenues may decline compared to the volatile period a year ago.
We continue to believe our opportunity is significant in licensing indexes for both AUM-linked ETF and non-ETF passive products, as well as in transaction-based listed derivatives products. In Analytics, subscription run rate growth was nearly 7% excluding FX. As Baer mentioned, we continue to gain traction in front-office use cases supported by tremendous strength in our factory analytics and our climate tools in recent quarters.
Additionally, our growth has been supported by firm-wide enhancements to our interfaces and progress in delivering broader, more flexible access to our content. However, as we have previously noted, we expect some lumpiness in the segment across both sales and cancels given the broad range of clients and use cases that we support. In our ESG and Climate segment, new recurring subscription sales grew 64% from the third quarter, as we saw some rebound in large-ticket deals in both ESG research and in Climate and tremendous traction in closing deals in EMEA.
Climate remains one of the most attractive growth engines for MSCI. Our firm-wide climate run rate reached $79 million, an increase of 80% from a year ago, reflecting exceptional growth across geographies, product offerings and client segments. Across all of our segments, we continue to see strong secular demand for mission-critical must-have tools and we continue to see a strong sales pipeline, although we remain cautious given the market backdrop. As we have mentioned previously in past periods of sustained equity market pullbacks, we can sometimes see slightly elevated levels of cancels and lengthening of sales cycles.
In connection with our downturn playbook, we continue to identify efficiencies to aggressively reposition our expense base to drive attractive profitability growth, while preserving investments in the most critical growth opportunities. As part of our regular review of our talent and our expense base in the fourth quarter, we took proactive actions to recalibrate our employee footprint, resulting in a $16 million severance charge, which was roughly $13 million higher than a year ago.
These tough actions have allowed us to preserve and even enhance our investment spending in certain key areas. This expense discipline coupled with our subscription revenue growth has enabled us to drive strong growth in adjusted EPS even through tough environments. The tremendous growth in our subscription base has been supported by doing more for our clients, continuing to penetrate newer, large addressable markets and capturing price increases, enabled by the continuous enhancements to our products and client experience.
During the fourth quarter, price increases contributed about 35% of our new subscription sales firm-wide across all products and more than 40% within index. We ended the year with a cash balance of $994 million, of which well over $600 million is readily available.
Free cash flow came in slightly below the low end of our previous guidance. We saw a small slowdown in client collection cycles as a result of extra approvals within certain clients, which we believe is related to the market backdrop, but we believe overall collections remain healthy and we see no issues around collectability. Our capital allocation framework which is focused on maximizing shareholder returns remained unchange.
We will continue to deploy our investment dollars towards the highest returning organic growth areas, return capital through a steady dividend that increases with adjusted EPS, opportunistically capitalize on share repurchases and pursue value-generative MP&A.
As Henry indicated earlier, we have decided to increase our dividend in the first quarter. We are not making any changes to our dividend policy or a broader approach to capital allocation. We have decided to shift our annual dividend increase from the third quarter, where we have historically announced the increase to the first quarter in order to more closely align with our annual planning process.
Lastly, I want to underscore that we also continue to actively evaluate and source bolt-on M&A opportunities, particularly in areas of unique content and differentiating capabilities such as private assets, climate and ESG, as well as fixed income. Lastly, I would like to turn to our 2023 guidance, which we published earlier this morning. Our guidance ranges reflect the assumption of continued volatility in financial markets, with overall equity market levels down slightly from current levels during the first half of the year and gradually recovering in the second half of the year.
Our expense guidance range reflects the efficiency actions we have taken in recent months and captures the investments we will continue to make in order to deliver growth. We expect normal seasonality in our expenses with $15 million to $20 million of elevated benefits and compensation-related expenses in the first quarter. I also want to highlight that our capex guidance reflects a continued high level of software capitalization as we continue to enhance our platforms and interfaces across product lines.
Our tax rate guidance highlights that we expect our effective tax rate to increase slightly year-over-year, primarily reflecting that we expect to receive a smaller windfall benefit in the first quarter as a result of where the share price is relative to the price at grant, as well as based on the amount of awards vesting. There could be pressure on year-over-year adjusted EPS growth in the first quarter due to the higher tax rate and the significant decline in average ETF AUM levels relative to the average levels during Q1 of last year.
Lastly, I want to highlight that our free cash flow guidance reflects the expectation of higher cash tax payments in 2023, as well as a slight degree of caution on client collection cycles based on the environment, consistent with what we saw in the fourth quarter.
Overall, we're well positioned for the year ahead and we're excited to continue to drive growth and differentiation. In periods of volatility and uncertainty, we believe MSCI is uniquely positioned to help our clients capitalize on unique opportunities and drive value creation. These are the times when MSCI thrives. We look forward to keeping you all posted on our progress.
And with that, operator, please open the line for questions.
