USA and ASG utilize the closed-end fund structure to provide equity like returns along with a steady distribution stream. So, I see that as being ideal for investors looking for income in a vehicle that differs from other structures that produce income, including annuities, open-end mutual funds, bond ladders, et cetera. So, we think investors will find the liquidity, transparency, distribution policy, and growth potential provided in this closed-end structure to be competitive with these other structures.
And while it's not exclusively a retirement vehicle and 2024 is now the peak of the boomer generation hitting age 65, and so we think these funds fit well within a retirement portfolio. As for specifics to USA and ASG, we think that unique multi-manager structure... And again, only a third of closed-end funds have the equity backing. And so, we think that within that structure, this multi-manager structure is unique.
And we think that whether you choose either the large cap version or the multi-cap version, provides the investors with not only income, but the growth potential of principal that will help them to retire comfortably. And so, as the managers of the funds, we're trying to provide manager selection, due diligence, rebalancing, ongoing monitoring, and an occasional replacement of portfolio managers.
And we think this allows investors more time to spend with the ones that they love, doing the things that they love to do and that are important to them. So, we think both USA and ASG should be considered by investors seeking income and growth. And the final point I'll make about multi-manager structures is to emphasize why consistency is so important. In my mind, it's for three reasons. The first we spoke about with regard to supporting the distribution policy.
The second is that we never know what the holding period of our investors are. And so, we strive to achieve satisfaction amongst the maximum number of shareholders at any time. And then the final reason is behavioral. We know retail investors underperform the holding period returns because they sell low and buy high. Our selection evaluation of managers seeks to avoid those actions.
