# DRC buckets

Download sample file: [DRC\_Bucket\_SECNONCTP.csv](../assets/csv/DRC_Bucket_SECNONCTP.csv)

This file provides a mapping from Region and Asset Class to DRC Sec non-CTP Bucket.

When the [DRC Trade Level](./sa-drc-trade) files omit the Bucket field for DRC Sec non-CTP, it is filled from this DRC Buckets file. To take advantage of this, the buckets file must be loaded before (or at the same time as) the DRC trade-level file.

This DRC Buckets file type is identified using the pattern: **\*\*/DRC\_Bucket\_SECNONCTP\*.csv** (as specified by drc.bucket.sec-non-ctp.file-pattern). A sample file is `DRC_Bucket_SECNONCTP`. This file is loaded using the **DrcSecNonCtpBuckets** topic. See the [Topic Aliases table](../dev/dev-ref-impl/dev-dlc/dlc-frtb-config#topic-aliases) for an understanding of the topic aliases associated with each topic.
