BNI / Berkshire exchange

[Kea]

Client owned shares of Burlington Northern Santa Fe. In Feb 2010 it was bought by Berkshire Hathaway. She got money + shares of Berkshire B.

I am having a hard time finding the details of this transaction. Was it a sale and purchase (i.e. taxable sale) or exchange (non-taxable)? Proceeds are shown on the 1099B (but no basis info). Brokerage is reporting it as a sale, but some of what I'm finding on-line indicates it was a tax free exchange (except for the cash portion). I've tried looking at the BNI site & the Berkshire site and cannot find any details.

If non-taxable exchange, does anyone have a link to the basis conversion calculations?

Has anyone found anything on this? Client can't find documents sent with merger info.

Thanks!

EDIT -- Oh, Never mind. I found it.

I swear I looked on this site before & couldn't find it.
