EXPLANATORY NOTE





This Amendment No. 1 on Form 10-K/A (this "Amendment") amends the Registrant's Annual Report on Form 10-K for the fiscal year ended December 31, 2012, which the Registrant previously filed with the Securities and Exchange Commission on April 16, 2013 (the "Original Filing"). The Registrant is filing this Amendment solely to (i) correct an error on the cover page of the Original Filing and (ii) reflect revisions to Part II, Item 9A related to disclosure controls and procedures. All other items of the Original Filing are unaffected by this Amendment and such items have not been included in this Amendment.  This Amendment No. 1 does not reflect events occurring after the filing date of the Original Filing or modify or update disclosures in the Original filing except to correct the omission on the cover page and amend Part II, Item 9A.





Portions of the Original Filing were subsequently amended by the filing of an 8-K (the “Recast 8-K”) on October 1, 2013 containing recast financial information and updating Part II, Items 6, 7 and 8.  On the date hereof, the Registrant is also filing and amendment to the Recast 8-K as of the date hereof to further amend Part II, Items 6 and 7 of the Original Filing.

Item 9A. Controls and Procedures





We maintain a system of disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit to the SEC under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and forms, and that information is accumulated and communicated to the management of our general partner, including our general partner’s principal executive and principal financial officers (whom we refer to as the Certifying Officers), as appropriate to allow timely decisions regarding required disclosure.





Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) (“Disclosure Controls”) will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. We monitor our Disclosure Controls and make modifications as necessary; our intent in this regard is that the Disclosure Controls will be modified as systems change and conditions warrant.





The management of our general partner evaluated, with the participation of the Certifying Officers, the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report, pursuant to Rule 13a-15(e) and 15d-15(e) under the Exchange Act. Based upon that evaluation, the Certifying Officers concluded that, as of the end of the period covered by this report our disclosure controls and procedures were effective at a reasonable assurance level.


Changes in internal control


No changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the quarter ended December 31, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.


The certifications of our general partner’s President and Chief Executive Officer and Senior Vice President and Chief Financial Officer pursuant to Exchange Act Rules 13a-14(a) and 15d-14(a) are filed with this Annual Report on Form 10-K as Exhibits 31.1and 31.2. The certifications of our President and Chief Executive Officer and Senior Vice President and Chief Financial Officer pursuant to 18 U.S.C. 1350 are furnished with this Annual Report on Form 10-K as Exhibits 32.1 and 32.2.
