I thought at one time i read that if the employer elects an averaging method of valueing plan assets, they could always switch to Market Value method, can't find where i may have read this. If i am correct does anyone have a cite? And if i'm not correct, please let me know. Thanks.

Might you be thinking of Rev. Proc. 2000-40? Section 3.10.

I might be, but is that still in effect under PPA??? Thanks.

I found no specific statement that it is "still in effect". However, it is clearly the pattern of IRS regulation, and now the express intent of PPA, to prefer using MV of assets. Some sections of Rev Proc 2000-40 are no longer applicable, but it is extremely unlikely the IRS would void section 3.10.
