NDMP TOC retention / mgmt class

[GIBIN]

I had recently setup NDMP backup between the EMC VNX NAS and my TSM server (v6.3.0 ) and am backing up the TOC during each full/diff backup .
The NDMP backups belong to a separate NAS domain with single management class (default )having retention of 2 months of data (full+diff)
I was wondering what retention does the data in the TOC storage pool follow ??( In my case the TOC storage poool is a disk pool ).

Which management class does it below to ??
