Thanks, Michael. Good afternoon, everyone, and thank you for joining us for StepStone's inaugural earnings call as a public company. I wanted to start today's call by thanking all of StepStone's employees for their hard work and commitment during these unprecedented times. We would also like to thank our clients for their partnership and the trust they continue to place in us. Finally, many thanks to all of our new shareholders for your vote of confidence.
As you know, we were able to successfully transition to a public company in September and are looking forward to continuing our journey to drive long-term value for our clients and shareholders. When we created StepStone, some of our founding principles included an entrepreneurial spirit and a strong equity culture. The IPO provided us with an opportunity to broaden equity ownership and a new tool that allows us to attract, retain and reward our team members. And we're proud to say that we now have over 500 employees that are Step shareholders.
Slide 2 of the presentation provides an overview of the results and highlights for the quarter ended September 30, 2020. Asset growth remained strong, with total assets under management up 23% over the last year to $72 billion. This was driven in part by the addition of approximately $3 billion in new separately managed account capital and approximately $1 billion in fundraising across our focused commingled funds, which Mike will walk through in more detail later in the presentation.
Our fee-earning AUM increased 22% during the last 12 months to $44 billion. Looking ahead, undeployed fee-earning capital, or capital on which we will earn fees once deployed or activated, stood at over $16 billion at the end of the quarter, and gross accrued carry increased by $158 million during the fiscal second quarter or 48% to $486 million.
Turning to a summary of our financial results. The rising fee-earning AUM translated into strong growth in management and advisory fees, adjusted net income and fee-related earnings. Fee-related earnings totaled $28.2 million for the quarter, an increase of 125% year-over-year, and included approximately $8.5 million related to the final close and subsequent retroactive management fees for StepStone Real Estate Partners IV. In turn, adjusted net income totaled $18.3 million or $0.19 per share for the quarter, up 59% year-over-year.
Now with a brief refresher, starting on Slide 4, we provide an overview of StepStone and our positioning in the private markets ecosystem. In our view, StepStone maintains durable competitive advantages across 5 key areas. First, our focus on customized solutions allows us to build portfolio specifically tailored to meet the needs of our clients.
Second, we have built a truly global yet local firm operating at scale with 19 offices across 13 countries, with nearly 40% of our team based outside of the U.S. and approximately 2/3 of our management and advisory fees coming from clients based outside of the U.S.
Third, we have invested heavily in proprietary technology that not only improves our operational efficiency, but also allows us to capture and analyze large amounts of data that flow through the StepStone platform.
Fourth, we have built specialized capabilities and expertise across the private equity, infrastructure, private debt and real estate asset classes, enabling us to provide clients with a complete private market solution.
And finally, we maintain a large and experienced team, a decentralized team-of-teams organizational structure and an entrepreneurial culture, empowering our teams to drive the growth you've seen in our business to date.
Turning to Slide 5. StepStone maintains an essential position in the private markets ecosystem. We work closely with our clients or limited partners to help facilitate the allocation of over $40 billion into the private markets on an annual basis by sourcing and analyzing over 3,200 investment opportunities per year alongside of our GP relationships. This allows our clients to leverage the StepStone platform to cover the increasingly global and the increasingly complex private markets in an efficient, informed and cost-effective way.
And the StepStone platform is becoming more powerful over time. As we work with more clients, we allocate more capital across a greater number of GP relationships, resulting in access to more data and more deal flow, helping us generate better returns and attract additional clients, thereby completing the virtuous cycle and creating a flywheel effect that is difficult to replicate.
Next, we lay out our comprehensive private markets platform on Slide 6. As a solutions provider, it is important to have a number of tools in our toolbox so that we can address a wide variety of challenges that our clients might face. In our case, that toolbox includes the 4 asset classes we previously mentioned; 3 core strategies, primary fund investments, secondaries and co-investments; and a number of different structures that we use to deliver our investment solutions.
First is separately managed accounts, which are essentially funds of one that are designed to meet the specific needs and objectives of a single client. At $33 billion of fee-earning AUM, this is the largest part of our business today and demonstrates our dedication to providing customized solutions.
Next, you have our focused commingled funds, which are aggregation vehicles that allow us to offer clients access to some of our most specialized investment strategies. As of the end of September, we managed $11 billion of fee-earning AUM and commingled funds or 25% of our total fee-earning AUM base.
Finally, we have our advisory and data services as well as our portfolio analytics and reporting offerings. Here, we work in more of an advisory capacity on everything, from initial portfolio construction and design to the ongoing monitoring and reporting of existing investments and everything in between. The advisory business, which is reflected in our $241 billion of assets under advisement, is part of what gives us our scale in the marketplace, allowing StepStone and its clients to deploy over $40 billion into the private markets on an annual basis and results in a significant advantage in deal flow, data and analytics.
Before I hand it off to Mike, I would like to reiterate our deep appreciation for all of StepStone's team members for their ongoing passion, commitment and hard work. We remain committed to leveraging the firm's durable competitive advantages around scale, diversification, geographic reach and proprietary data and technology capabilities to continue to provide customized and integrated investment solutions to our clients.
With that, I'll pass it over to Mike McCabe, our Head of Strategic Planning. Mike?
