Defined Contribution (401 k) Tracing
Pension Evaluators/QDRO Consultants has
pioneered several methods of tracing the passive growth of
pre-marital account balances for defined contribution plans.
These tracings are jointly performed by our CPA and a present
value expert.
Keep in mind that the account value of a
defined contribution plan is the present value. What you see
is what you get. There are many kinds of defined contribution
plans including 401 (k) plans, profit sharing plans, thrift
and savings plans, employee stock ownership plans (ESOPs),
individual retirement accounts (IRAs), Keoghs (HR 10s), money
purchase plans, stock bonus, target plans, simplified employee
pension plans as well as 403 (b)s.
Determining the amount of the plan available
for equitable distribution becomes more complicated when a
balance already exists at the time of the marriage. Most states
have code sections like this one from Ohio providing that
the “passive income and appreciation acquired from separate
property by one spouse during the marriage” is separate
property [ORC Section 3105.17.1(A)(6)(a)(iii)].
Tracing the passive growth of separate property
can be done in a number of ways. If the investment vehicles
are mutual funds and the record of exchanges and transfers
is clear, we find tracing the growth of the pre-marital account
balance with Morningstar’s Principia Pro software program
to be a straightforward process. At other times the company
may offer yearly rates of return for various non-mutual fund
investments in addition to a detailed record of the money
movement. This process is not nearly as accurate as tracing
monthly transfers but it is frequently a reasonable alternative.
Sometimes, however, tracing passive growth
can be as challenging and frustrating as following a strand
of spaghetti across a plate. For the difficult cases or those
where we only have periodic plan statements we employ the
following three-step process:
- The account balance on the date of the
marriage is determined – typically by interpolation.
- That separate property is then “grown”
by an annualized factor. This is determined by subtracting
the opening balance from the closing balance for the time
period involved. The difference between the account balances
is comprised of two elements: contributions and growth (or
losses!). Next, all contributions, both employer and employee,
are subtracted from the result. The difference, of course,
is the growth for the intervening period. Dividing the sum
representing growth by the opening balance yields a growth
rate that is then applied to that nonmarital account balance.
The step is then repeated for each statement period using
the newly derived account balance for the beginning of that
period.
- The final marital and nonmarital account
balances must then be adjusted downward to reflect that
the “grown” account balances are invariably
too large. This stems from the fact that the growth factor
overstates the actual statement growth. This refinement
is accomplished by allocating the actual statement balance
into marital and nonmarital components in the same percentages
as the derived account balances.
