Do Employer Contribution Accounts have to be separate?

[Guest sarasf]

A profit sharing plan says "An Employer Contributions Account shall be established for each Participant to which the Administrator shall credit, or cause to be credited, Employer Contributions and forfeitures attiributable to Employer Contributions plus earnings and losses thereof." Do the accounts have to be acutal separate accounts, or can there just be one account for the entire plan with calculations of "account" value made when necssary for distributions?

The term "Account" as used in the plan document refers to a bookkeeping function, not to a physical division of the money.
