Has anyone figured out how to get their financial management software to track this balance? Somehow Empower picked up on the fact it exists, but shows a 0 balance.

My Empower (personal capital) picked it up as well... even though I opted out 🤔

I'm sure you know this, but the MBCBP isn't a 60/40 allocation. It's a 40/60 allocation.

Correct. The MBCBP is 40/60. The interesting portion of the linked article was the discussion about bond allocation hurting the retruns. The article showed how the 40% bond allocation in the 60/40 didn't save the portfolio, in fact the rapid rise in interest rates crushed the bond portion. The MBCBP 60% bond exposure would have likely suffered a similar fate.

It was a particularly bad year. But it also was a result of a correction to a pent up historical abnormality (near free money).

You have a source for this? Where is the money actually located?

Contract lays it out. Section 26.S.7. Notepad 23-18 breaks down the rest.

Money is in a collective investment trust. No actual retail fund. Company self manages the assets as they do with the remaining frozen DB plans.

From the FAQ on Fidelity’s site:

What is the investment portfolio for the MBCBP? How are the funds held?

The investment strategy for the MBCBP will target an allocation of 40% to global public equity markets in a manner similar to the MSCI All Country World Index, and 60% to U.S. intermediate bonds in a manner similar to the Bloomberg US Aggregate Bond Index. The MBCBP assets will be invested in a Collective Investment Trust (“CIT”), which is a pooled retirement investment vehicle only available to a qualified retirement plan that offers benefits not available via a traditional mutual fund.

lol, are y’all surprised that the investment of your money is completely obfuscated?

Blackrock. Did you forget they leaked that back during negotiations, they tried to say that's not what they meant?
