Lost Earnings in Segregated Broker Accounts

[Guest 401KAmerica]

I have a 401k Plan. They have 28 segregated Brokerage accounts, one for each Particpant.

The Trustee sends the money to the Trust on time each payroll period.

The Brokerage House does not credit interst to the cash postions?

How do you go about calculating lost earnings, since the cash position changes everyday/month due to account activity.

Maybe I am missing the point here, but what are these "lost earnings" the result of? Is this a question of money goes to broker and it sits for day or two before being invested? Or is the money sitting for long periods in non interest bearing account.
