Item 1.03. Bankruptcy or Receivership.

Confirmation of Plan of Reorganization

As previously disclosed, on November 16, 2011, Trailer Bridge, Inc., a Delaware corporation (the “Company”), filed a voluntary petition in the United States Bankruptcy Court for the Middle District of Florida (Case No. 3:11-bk-08348) seeking relief under the provisions of Chapter 11 of the United States Bankruptcy Code (the “Bankruptcy Code”). On March 16, 2012, the Court confirmed the Company’s second amended plan of reorganization for Trailer Bridge, Inc. (the “Amended Plan”), which was filed with the Bankruptcy Court on March 14, 2012. The Amended Plan provides for the consummation of certain restructuring transactions and the treatment of claims and equity interests against or with respect to the Debtor, as set forth below. The Amended Plan provides that all existing shares of common stock will be cancelled on the effective date of the plan and new shares of common stock will be issued as set forth below.

Except as otherwise noted, holders of allowed claims against the Debtor will receive, in exchange for such claim, an amount in cash equal to the allowed amount of such claim. Holders of claims in respect of obligations under the Wells Term Loan and Security Agreement, dated June 14, 2007 and the Wells Loan and Security Agreement, dated April 23, 2004 will receive in exchange for such claims an amount in cash equal to the allowed amount of such claims. The MARAD 6.52% and 7.07% Indentures will be reinstated. Holders of claims in respect of obligations pursuant to the 9.25% Senior Secured Notes Due 2011 Indenture, dated as of December 1, 2004 (the “9.25% Notes”), shall receive that holder’s pro rata share of a new note in the principal amount of $65 million. Holders of the 9.25% Notes shall also receive their pro rata share of 48,950 shares of new common stock which will represent at least 91% of the Company’s outstanding shares of common stock.

Holders of general unsecured claims shall receive their pro rata share of a reserve, initially funded in the amount of $3.5 million. The Debtor currently estimates that holders of allowed general unsecured claims shall receive a distribution of greater than 85% of their allowed claims. If the holders of allowed general unsecured claims receive a distribution of greater than 85% of their allowed claims, then holders of the Company’s existing common stock shall receive, on the terms and conditions set forth more fully in the Plan, either (i) cash payment of $.015 per share; or (ii) their pro rata share of new common stock and warrants. If the holders of the allowed general unsecured claims do not receive a distribution of greater than 85% of their allowed claims, the holders of the Debtor’s existing common stock will receive nothing and such new shares will be distributed pro rata to the general unsecured claimants. The record date for the distribution of new shares shall be the date of entry of the confirmation order on the docket of the Bankruptcy Court.

Even after the Bankruptcy Court enters the order confirming the Amended Plan, the Amended Plan will not become effective until the occurrence or waiver of certain conditions precedent, including but not limited to, the (i) entry into an exit facility and all conditions precedent to funding under such facility shall have been satisfied or waived, (ii) all authorizations, consents and regulatory approvals required, if any, in connection with the consummation of the Amended Plan shall have been obtained, and (iii) all actions, documents and agreements necessary to implement the Amended Plan shall have been effected or executed. The Debtor anticipates that the effective date of the Amended Plan will be on or about March 30, 2012. All shares of existing common stock will be cancelled effective on the effective date of the Amended Plan.

The Company anticipates that it will file a Form 15 with the Securities and Exchange Commission on or about March 30, 2012 that will terminate its reporting obligations under the Securities Exchange Act of 1934.

The discussion of the Amended Plan herein is a summary and is qualified in its entirety by the Amended Plan attached hereto as Exhibit 2.1 and incorporated by reference herein.
