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 seeking relief under the provisions of Chapter 11 of the United States Bankruptcy Code (the “Bankruptcy Code”).

In accordance with General Instruction B.2 of Form 8-K, the information in this Item 7.01 shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall such information be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as shall be expressly set forth by specific reference in such a filing.

Cautionary Statement Regarding Financial Operating Data

The Company cautions investors and potential investors not to place undue reliance upon the information contained in the Monthly Operating Report, which was not prepared for the purpose of providing the basis for an investment decision relating to any of the securities of the Company. The Monthly Operating Report is limited in scope, covers a limited time period and has been prepared solely for the purpose of complying with the monthly reporting requirements of the Bankruptcy Court. The Monthly Operating Report was not audited or reviewed by independent accountants, was not prepared in accordance with Generally Accepted Accounting Principles in the United States, is in a format prescribed by applicable bankruptcy laws, and is subject to future adjustment and reconciliation. There can be no assurance that, from the perspective of an investor or potential investor in the Company’s securities, the Monthly Operating Report is complete. The Monthly Operating Report also contains information for periods which are shorter or otherwise different from those required in the Company’s reports pursuant to the Exchange Act, and such information might not be indicative of the Company’s financial condition or operating results for the period that would be reflected in the Company’s financial statements or in its reports pursuant to the Exchange Act. Results set forth in the Monthly Operating Report should not be viewed as indicative of future results.

Investors are cautioned that any such forward looking statements are not guarantees of future performance and involve risks and uncertainties, and that actual results may differ materially from those in the forward looking statements as a result of various factors. Without limitation, these risks and uncertainties include, (i) potential adverse impact of the bankruptcy case on our business, financial condition or results of operations, including our ability to maintain contracts and other customary and vendor relationships that are critical to our business and the actions and decisions of our creditors and other third parties with interests in our bankruptcy case; (ii) our ability to maintain adequate liquidity to fund our operations during the bankruptcy case and to fund a plan of reorganization and thereafter, including maintaining normal terms with our vendors and service providers during the bankruptcy case and complying with the covenants and other terms of our financing agreements; (iii) our ability to obtain court approval with respect to motions in the bankruptcy case prosecuted from time to time and to develop, prosecute, confirm and consummate a plan of reorganization with respect to the bankruptcy case and to consummate all of the transactions contemplated by such plan of reorganization; (iv) risks associated with third party seeking and obtaining court approval to terminate or shorten the exclusivity period for the company to propose and confirm a plan of reorganization, for the appointment of a Chapter 11 trustee or to convert the Chapter 11 Case to a Chapter 7 case; and (v) those factors identified in our filings with the Securities and Exchange Commission as may be accessed at www.sec.gov.
