https://www.askaboutmoney.com/threa...on-consumer-debt-or-show-their-wealth.214753/ covered some past discussion on if db or DC pensions are included. Probably need to try and read the report to figure out. But I'm guessing db pension are not and DC pension is included.
I googled the 60 page credit suisse report. Copy paste of a section below. Private pension assets are included. State entitlement are not. It's Not explicit on db pensions but the implication is they are not included, and that an annuity would not be included either.
Notes on concepts and methods
Net worth, or “wealth,” is defined as the value
of financial assets plus real assets (principally
housing) owned by households, minus their
debts. This corresponds to the balance sheet
that a household might draw up, listing the items
which are owned, and their net value if sold.
Private pension fund assets are included, but not
entitlements to state pensions. Human capital is
excluded altogether, along with assets and debts
owned by the state (which cannot easily be
assigned to individuals).
