Thank you, Mike. Moving on to Slide 12 of the presentation to touch on financial highlights. Consistent with the prior quarter, our financial performance reflected continued strong growth in fee-earning AUM, having positive revenue trends with temporarily depressed travel-related spending related to the pandemic, further enhancing fee-related earnings and adjusted net income. This being our first full quarter operating as a public company, we have seen the impact of elevated professional fees and D&O liability insurance hitting our G&A expense line.
Fee-earning AUM ended the quarter at $46.6 billion, up 18% year-over-year. Management and advisory fees for the quarter increased 6% to $70.1 million and is up 22% year-to-date. As we have highlighted in the last bullet point, results for the prior year quarter included approximately $4.8 million retroactive fee related to additional closes for StepStone Secondary Opportunities Fund IV and onetime success-based advisory fees.
Fee-related earnings totaled $22.3 million for the quarter, up 5% year-over-year and is up 48% year-to-date. Year-over-year growth for the quarter was skewed by $4.2 million of FRE included in the prior year quarter related to the retroactive fees and success fees previously mentioned. ANI per share increased 56% for the quarter and up 44% year-to-date.
Turning to other key highlights on the table. Undeployed fee-earning capital that will generate fees over time as this capital is invested or activated stood at over $17 billion as of December 31. FRE margins held steady at 32% for both the quarter and prior year quarter and were up 600 basis points year-to-date to 33%, reflecting revenue growth and a favorable expense environment.
As I mentioned last quarter, we don't view this margin as a normalized operating margin. Margins are elevated given the current operating expense environment. We will continue to benefit from lower G&A spend until we are able to return to our offices and begin seeing clients in person. As a counter to this benefit, we will continue to see higher costs associated with being a public company migrate into our G&A expense line over the next few quarters. We have approximated that as reported results were adjusted for normalized T&E and other expenses that did not occur, FRE margins for the quarter and year-to-date would be 400 to 500 basis points lower than reported. These trends will influence our G&A expense and overall margins for the near term.
Gross realized performance fee totaled $26.4 million for the quarter, up 33% year-over-year. Quarter-over-quarter trends and comparisons can vary, reflecting the timing of realization activity that is beyond our control.
Page 27 in the appendix provides quarterly and LTM net performance fee trend. As we have discussed previously, we believe the longer-term view on performance fees is more appropriate.
And finally, adjusted revenues increased 12% for the quarter and 18% year-to-date.
Turning to Slide 13. We'll walk through core revenue trends in more detail on a year-to-date and last 12-month basis, starting with management and advisory fees at the top. Fee revenue was up 22% for the year-to-date period and 23% for the last 12 months.
More specifically, management fees increased 25% year-to-date and 26% for the last 12-month period, driven by strong growth in fee-earning AUM across our SMAs and commingled funds. Mike mentioned and as shown on the bottom of Page 10, we have seen steady overall blended fee rates in the low 50 basis point range. Advisory-related fees were up 13% year-to-date and 14% for the last 12 months, reflecting increased client activity. We provided a more detailed breakdown on management and advisory fees on Page 26 in the appendix.
Gross realized performance fees were $48 million for the first 3 quarters of fiscal '21, up slightly compared to the prior fiscal year-to-date period and down about $5 million over the last 12 months, reflecting relative realization activity for these periods. As mentioned, Page 27 provides quarterly and LTM net realized performance fee trends.
The bottom chart shows adjusted or cash revenue, which increased 18% year-to-date and 16% over the last 12 months, driven by higher management and advisory fees and partially offset by lower realized performance fees for the LTM period.
Turning to our core profitability metrics on Slide 14. Fee-related earnings of $68 million for the first 3 quarters of fiscal year 2021 was up 48% compared to the same period a year ago, while FRE over the past 12 months was up 50% to $84 million. Year-over-year growth was driven by higher fee-earning AUM, rising client advisory activity and expanded margins.
FRE margins increased from 27% to 33% for the first 3 quarters of 2021 and from 25% to 31% for the last 12 months. Consistent with earlier comments, we will continue to benefit from lower T&E spend until we're able to return to our offices and begin seeing clients in person. As a counter to this benefit, we will continue to see higher costs associated with being a public company in our G&A expense line.
As stated earlier, we have approximated that as reported results were adjusted for normalized G&A expenses that did not occur, FRE margins year-to-date would be 400 to 500 basis points lower than reported, and they would be down slightly less than that on an LTM basis. The impact of these trends will influence margins in the near term, and we would expect these margins to migrate down in the near term.
Adjusted net income increased 46% year-to-date and 38% for the LTM period, driven by higher fee-related earnings combined with higher net realized performance fees.
On Slide 15, we highlight a couple of key balance sheet items. First, gross accrued carry continues to build, ending the quarter at $637 million, up 66% over the last 12 months. As a reminder, changes in our accrued carry balance reflect unrealized gains or losses and valuation of the underlying portfolios on a 1 quarter lag. We think of accrued carry as a backlog of amounts that will convert to cash over time given the diversification of our investment portfolio, the number of carry eligible program and GP provided, of course, that investment performance remains strong across cycles.
On the bottom chart, our proprietary investment portfolio ended the quarter at $63.4 million, up 28% over the last 12 months, primarily reflecting market appreciation and net addition, while unfunded commitments to these programs held steady from the prior quarter at approximately $61 million.
As shown on Slide 16, we manage a large pool of performance fee-eligible capital over $41 billion as of December 31. Importantly, this capital is widely diversified across approximately 120 programs, including over 80 with accrued carry position. More than 60% of our unrealized carry at year-end is tied to programs with the 2015 or earlier vintage, indicating that these funds are past their investment period and in harvesting mode. Approximately 64% of this carry is sourced from vehicles from vehicles with deal-by-deal waterfalls and realized carry to occur at the timing of investment exit. We've provided additional material in the appendix for review.
This now concludes our prepared remarks. I'll now turn it back over to the operator to open up the line for any questions. Operator, please open up the call. Thank you.
