Representative Dave Camp, Republican Chairman of the House Ways and Means Committee, has released a discussion draft on new rules for the taxation of derivatives. The press release is here. Detail material is found here.
In the draft, derivatives used for hedging are excluded. The criteria proposed here for determining whether a derivative is used for hedging in tax accounting are similar to the criteria already applied in financial accounting. However, a large fraction of derivatives held by non-financial companies are not accounted for using hedge accounting. So, it seems to me that this proposal would probably affect the tax treatment of those holdings.
It will be interesting to see how this discussion unfolds.
