What's happened is a front corporation was established and passed on a $1 million campaign contribution to a PAC. The corporation is then dissolved and per FEC Rules (likely under section 431(8)(B)(v)), the contribution is legal as long as it is used to submit printed information pertaining to the primary candidate's presidential campaign in the form of mail-order notifications, etc., etc. Furthermore, per section 441b(b)(1), because there was no "greviences, labor or wage disputes, or anything associated with employee-related problems, the "corporation" or "labor organization", does not have to disclose where they got the money from. The missing part of the puzzle here, folks, is PAC! But if you read between the lines, for the purpose of providing financial aid to Mitt Romney's presidential campaign, the "labor organization" could have easily been viewed as either the LLC corporation or the PAC. Now that the LLC has been dissolved, you can't easily go back and force the disclosure of who the actually business owners were. As such, the PAC can just deny they ever knew who made the contribution and as long as the Romney camp sends out fliers or other printed materials, they can get away with this.
