Item 2.01.
Completion of Acquisition or Disposition of Assets.
On April 12, 2013, pursuant to an Agreement and Plan of Merger dated February 6, 2013, (the "Merger Agreement") by and among Reliance Steel & Aluminum Co., a California corporation ("Reliance"), RSAC Acquisition Corp., a Delaware corporation and a wholly-owned subsidiary of Reliance ("Merger Sub"), and Metals USA Holdings Corp., a Delaware corporation ("Metals USA"), Merger Sub was merged with and into Metals USA, with Metals USA surviving the Merger as a wholly-owned subsidiary of Reliance (the "Merger").  Pursuant to the terms and conditions of the Merger Agreement, at the effective time of the Merger, each outstanding share of Metals USA common stock (other than dissenting shares, treasury shares, shares owned by Reliance and its subsidiaries and shares owned by any subsidiary of Metals USA) was cancelled and converted into the right to receive $20.65 in cash, without interest.  Also at the effective time of the Merger, each option to acquire Metals USA common stock granted under any Metals USA equity incentive plan, whether vested or unvested, that was outstanding became fully vested and was converted into the right to receive an amount in cash equal to the product of (i) the excess, if any, of $20.65 over the per share exercise price of the option multiplied by (ii) the total number of shares of common stock subject to the option.  Each share of restricted stock granted under any Metals USA equity incentive plan, whether vested or unvested, was cancelled and converted into the right to receive $20.65 per share in cash.  The aggregate merger consideration for such shares, stock options and restricted stock was approximately $786 million.
Reliance funded the merger consideration with existing cash on hand, borrowings under its new term loan and revolving credit facility and proceeds from the issuance of its senior notes.
