Yes. Thanks, Paul. Look, net flows reflect the trends of premiums and deposits as against the surrender behavior. As Mark pointed out, we haven't really seen much material change in the surrender behavior a little bit within sort of expected margins, but premiums and deposits is really another story.
And we said that the second quarter last year was going to be the low water mark. It certainly was. And in fact, the first quarter of this year is one of the largest sales quarters we've had in the Individual businesses since we created AIG Financial Distributors. And while the month of January was actually still below last year, and we consider last year's first quarter a pre-COVID quarter because, really, the pipelines were full right through March, April. We saw growth from February over January, March over February a pretty significant growth.
So the end of the quarter, we're really back at what we consider to be normal run rates for that business. And as Mark pointed out, both index and variable annuity, very strong for us there.
And so the one line of business, fixed annuities, they're a little bit lower than historical levels, but we also saw recovery in fixed annuities towards the end of the quarter. And so we're feeling optimistic about the forward curve for the individual business. And as Mark pointed out, across annuities, because we've announced relative to the retail mutual funds, right, we had positive flows. So I'm confident relative to the flows in the Individual Retirement business.
For Group Retirement, it's a little bit of a different story. The group acquisitions -- the new group acquisitions actually were one of our strongest quarters and increased by $150 million over the prior year, whereas periodics were down about $50 million, and I think that reflects furloughs and people leaving the workforce. And then the non-periodic were also down a little bit for a variety of reasons.
And in the Group Retirement business, we still see some modest negative flows, but I think that reflects the fact that we're a small, medium-sized plan provider. And in the consolidation that continues to go on in health care, we do see some of that large case consolidation. But the assets under management have continued to grow, obviously, supported by equity markets, and that's an important base of earnings for the fee side of the business.
So we feel confident. We're being careful about capital deployment. We're seeing conditions improve, and our diverse product range and channel allow us to be careful where we deploy the capital, and we're seeing that start to come through in the first quarter.
