Withdrawal of a Master Limited Partnership from a retirement account

Hello,

 

I hold Master Limited Partnership units in my retirement account (a Roth IRA).  I've held them for 5+ years, and I've had the Roth IRA for 5+ years.  I am over 59 1/2 years old.

 

Is a withdrawal of Master Limited Partnership units from an IRA or Roth IRA to a regular brokerage account treated as an in kind transfer, or is it treated as a sale by the retirement account and purchase by the regular account?  The owner of the retirement account and the owner of the regular account are the same individual (me).

 

If anyone knows the answer (is withdrawal of MLP units from a retirement account to a regular brokerage account with the same owner treated as a sale of the units by the retirement account, or not?) I would love to read the answer.

 

Regards
