Definition of Master Trust?

[Guest rachd]

While reviewing the instructions closely for line 4j of Schedule H, I noticed the following statement: "If the Schedule H is attached to a Form 5500 filed for a plan with all plan funds held in a master trust, check "No" on line 4j." I would love not to have to compile this info but am not sure if "master trust" applies to this plan.

What exactly is a Master Trust?

This particular plan has all assets with Wells Fargo, who directs what amounts are invested where (without any input from the employer). They also sign the Schedule P.

Thanks,

Page 9 of the Form 5500 instructions for 2002 describes a Master Trust Investment Account.
