Sure. Assume you have a private corporation, so its equity is not publicly traded. It is a private corporation with equity not traded. It has a greater than 50% interest in a partnership; there are other partners, and they're going to develop a specific property, a resource property. It really doesn't matter what the focus of the business is. That corporation issues debt in the public market and then uses that debt to finance its investment in the partnership. Again, it's not a partnership whose equity is publicly traded.
Based on the current drafting, that partnership becomes a SIFT and is treated as a corporation and is subject to these rules. Although, as you may know, partnerships are not taxable themselves, all their income gets allocated out to the partners and is taxed in the partners' hands, so what you're doing is imposing a level of corporate tax on the partnership, even though all of the income of the partnership would be allocated out to the partners, and in this case one of the partners is a corporation that is going to be taxed anyhow.
