Yep, that happened in 2012 when Vanguard had a fee dispute with MSCI and moved about 2 dozen indexes from MSCI to CRSP and FTSE.
As for VG Total Stock Market Index (VTSAX/ VITSX/ VTI), it also has a smaller but separate cousin VG Institutional Total Stock Market Index (VITNX, no ETF class) that confusingly has significant annual CG distributions.

@msf
Thanks for the link re QLAC
While it is old (2015) and uses the RMD date of 70 1/2 and an anticipated return of 8% yearly, it is still probably correct that you have to live a long while past 85 to come out ahead.
I am not sure MaxiFI would model this for you, but it might. The calculations are not difficult. What you want to know other than how long you will live is the expected return ( or lack thereof) on your IRA assets required to beat the QLAC. I doubt tax rates will go down any.

This is a WSJ report which may require a subscription to read.
"Everyone knows the New York Stock Exchange. And its rival, Nasdaq.
But there is a mutual fund that invests in stocks based on a relatively unknown market index that has grown so large it might be considered a third stock market unto itself.
That fund is the $1.3 trillion (yes, trillion, including all share classes) Vanguard Total Stock Market Index Fund (VTSAX) and its exchange-traded-fund shares. The fund, from Vanguard Group, now accounts for 10% of all assets in U.S. stock mutual funds and ETFs in the market, according to Morningstar Inc. No other mutual fund or ETF comes close to it in asset size. The next largest is an $821 billion Vanguard S&P 500 index fund.
The paradox is that this biggest beast among funds is tied to the most unassuming of stock indexes—the CRSP U.S. Total Market Index, developed at the University of Chicago’s Booth School of Business."
Journal Report

Most Medicare Part B participants pay a premium that covers 25% of the actual cost of the coverage. (The government picks up the rest, using general tax revenue.) In 2021, that 25% comes to $148.50/mo, or $1782/year.
If one's MAGI¹ (AGI from line 7 of form 1040 plus tax-exempt interest from line 2a) is above $88K (single or married filing separately) or $176K (married filing jointly), then one's share of the actual Part B cost increases.
If one's MAGI is just over this threshold, then instead of paying 25% of the cost of Part B, one will pay 35%. That's a 40% increase (35%/25% = 1.4x). So in 2021, the first level of IRMAA comes to 40% x $148.50 = $59.40/mo, or $712.80/year.
https://www.medicare.gov/your-medicare-costs/part-b-costs
There are also higher brackets, where one pays 50% of the actual part B cost (IRMAA = 100% of Part B premium), 65% of Part B cost (IRMAA = 160% of premium), 80% of part B cost (IRMAA = 220% of premium), or 85% of part B cost (240% of premium). No matter what one's income level, the government is still picking up some of the tab.
https://secure.ssa.gov/poms.nsf/lnx/0601101031
In 2022, the first threshold is at $91K ($182 married filing jointly), and IRMAA is $68/mo. All the thresholds for 2021 and 2022 along with the total (part B premium plus IRMAA) amounts are on the Medicare.gov site given above.
¹MAGI is calculated using the last income tax return filed. For 2022 IRMAA, that is the income tax form for 2020, filed as recently as just two months ago, including extensions. Your Jan 2022 IRMAA can't be based on 2021 income since you haven't reported it yet.

The info on brackets I have are ( MFJ vs Single)
zero IRMAA under $176,000 $88,000
$59 /mo/person $176,000 to $222,000 $88,000 to $111,000
$148.50/mo/person $222,000 to $276,000 $111,000 to $138,000

@Derf - The hoops is a reference to Fido requiring you to acknowledge (by clicking an accept icon) that you have read and understand the warning and that you feel experienced enough to proceed with the purchase.
Next bet? Nothing looks attractive, No major changes except continuing a near month-long 4-5% bet on TAIL (which requires you to acknowledge a warning at Fido). It’s not enough to overcome gains if the market continues upward, but serves as a “brake” in sharply declining markets, limiting losses. Rose .81% yesterday. The effect of holding a small amount is similar to driving forward while riding the brake a bit.
PS - The other kind of hoops. :) Been on the losing end of a few lately. Taking a breather.

I remember when SUVs really were utility vehicles.
They were often owned by hunters, fishermen, boaters, etc.
These SUVs were rugged, functional vehicles with very few amenities.
Since that time, many SUVs were upscaled and their prices have escalated dramatically.
Auto makers ramped up marketing and production of SUVs to capitalize on this segment's
high profit margins.

I feel that longevity insurance is one of the few useful products that the financial industry has created in the past several years. That said, if it's not a product that you are interested in independent of tax considerations, then buying a QLAC is a poor way to reduce RMDs.
Kitces, Why A QLAC In An IRA Is A Terrible Way To Defer The Required Minimum Distribution (RMD) Obligation

Getting back to timing of conversions ... Though recharacterizations (undo's) of conversions are no longer allowed, there are a couple of other tactics that provide some or much of the same effect.
One is to use a recharacterization that is still permitted. A contribution as opposed to a conversion can still be recharacterized. So if you contributed $6000 to a Roth IRA in 2021 but in doing your taxes you discover that you'd have been better off taking the deduction, you can recharacterize the $6K as a contribution to a traditional IRA. (You can also do the opposite: contribute to a T-IRA and then recharacterize it to a Roth.)
https://www.irs.gov/retirement-plans/retirement-plans-faqs-regarding-iras#Recharacterization of IRA Contributions
Another it to take advantage of the 60 day rollover rule (sometimes limited to one per year). One could withdraw money from a T-IRA near the end of the year, and then early the next year when the tax situation is clearer (and within 60 days of the withdrawal) either put the money back into the T-IRA (60 day rollover), put the money into a Roth (indirect rollover conversion), or split the money between a T-IRA and a Roth.
If any money goes back into a T-IRA, you can't do this again for another 365 calendar days. The restriction is according to days, not fiscal years.

If I set aside comparative performance of my bonds--- all in funds--- and look at raw dollar figures, the monthlies will be a big help in the new year. We incurred a big (for us) one-time expense, buying furniture. Zero interest for 12 months. I've resisted taking the divs. in order to keep them growing. But it's time. Basically, if we control our spending, we are at least mitigating the inflation "out there" in the stores. And it's nice to have connections, too: for $25, we can get an entire, HUGE, Ahi for cooking, for poke ("po-kay") and sashimi. My wife knows how to make the best of a fish with a knife!

@ Hank
Does it matters what you convert, if you can always buy or sell anything in either account tax free?
Once you have the capital in a Roth, I agree it should be probably devoted to more risky, long term investments.
Converting before you are on Medicare and after are two different calculations.
It is important to remember that the IRMAA surcharges go from zero dollars ( B Medicare Premium $1776 /year in 2021) to $700 for ONE DOLLAR of income ( AGI before the standard deduction) above $176,000 for a couple and $111,000 single. A couple would therefore pay $1400 extra.
IRMAA is based on two years before 1040, so 2022 will look at 2020 AGI. Once you file 2021 taxes in 2022 you can ask for redo, if your 2021 income is lower. It takes a month or so, so you will end up paying more for a few months.
One strategy I am considering is to do a large conversion, all in one year, before I take SS at 70. Then the impact of the conversion on the IRMAA will be limited to one year.
Other things to consider. IRS lets you put up to $135,000 in a QLAC which will reduce you RMD proportionally.

He also runs a web site with a neat financial planning program for $100, Maxifi. It may be overkill for a lot of folks, but it will allow you to run all sorts of projections and scenarios about Roth conversions pretty easily

The question can be split into two parts:
1. Best time during a given year
2. Best year
1. In theory, the best time within a year to convert is when your T-IRA portfolio is at its nadir. Which is great if you can see into the future.
Pragmatically, waiting until there's a market correction (10% dip or more) can leave you converting at a higher value than converting now. If the market rises 15% while you're waiting and then drops 10% (to 103.5% of your starting value), what's the point? Or if you're planning on converting a bit each year, you can easily wind up stuck at the end of the year with a higher market still waiting for that correction.
If you're trying to keep MAGI under a certain "cliff" threshold (e.g. for ACA subsidies or to avoid IRMAA) then you should likely be conservative and top off your conversion near year end once you have a better handle on MAGI YTD. If your concern is about edging into another tax bracket, it's not a big deal if you wind up a few dollars over or under, so don't wait until year end for that reason.
2. If you're converting and paying taxes with non-IRA money, sooner can be better than later even if your expected tax rates in the future will be a little higher. That's because you're effectively adding money to your IRA by prepaying your taxes. (A dollar in a Roth is worth more than a dollar in a T-IRA.)
OTOH, many states give tax breaks for retirement income (including Roth conversions) once one reaches a certain age. So it can be advantageous to wait until then. You might convert between the time you reach that age and the time you retire and actually start drawing money from your T-IRA and/or pension (and possibly using up that tax break).
Several states give some sort of help on Medicare Part D prescriptions, where your income needs to be low enough to qualify. Doing Roth conversions earlier (even at somewhat higher tax rates) may help qualify for these or other income-related programs.
The largest such program is EPIC in NYS. Its income cutoff is decidedly middle class: $75K single, $100K married.
The rule of thumb short answer is the sooner the better (both within year and across years); just don't do too much in a single year and keep various income thresholds in mind. And if you're thinking of making charitable contributions, keep some money in the T-IRA so you have it available for QCDs.

The best time to convert to a Roth is when income is low, taxes are anticipated to be higher in the future, and when the value of the asset is low such as a market correction.

There is already a transition place in place for a number of years including Greg Abel, Ajit Jain, and Todd Combs. I believe Abel is the one responsible for investing in Apple and dumped IBM (a long holding for many years). Now Apple accounts for over 40% of BRKA portfolio.

The CEO sent out an email apologizing for the problems people are having connecting to Schwab: Link
I’m on Quicken for Mac and switched over to the new Schwab connection early in the process and haven’t encountered any issues.

Not all is bleak today. Gold’s picked up $23.00 and the miners are up better than a half percent.

I am pretty sure "Mommie" Vanguard refuses to let you trade any short or leveraged ETF

It’s crazy in some ways. You can buy DFKG (down 12% today) at Fido w/o any warning. But you get one when you try to buy DFND - which isn’t all that risky. But it holds a 25% constant short position. Than there’s TMSRX, which can of course short equities, but prompts no warning. I haven’t come across anything you can’t trade at Fido. Just some hoops to jump through.
