FINANCIAL RESULTS

An overview of the financial performance for the three months ended March 31, 2013, as compared to the three months ended March 31, 2012, includes:

·                  Direct operating costs and expenses were $16.7 million compared to $14.0 million due to increases in direct operating costs and expenses at the Gulf Coast, Midwest, Brownsville and Southeast terminals of approximately $0.8 million, $0.3 million, $1.2 million and $1.2 million, respectively, offset by a decrease in direct operating costs and expenses at the River terminals of approximately $0.6 million.

Our terminaling services agreements are structured as either throughput agreements or storage agreements.  Most of our throughput agreements contain provisions that require our customers to throughput a minimum volume of product at our facilities over a stipulated period of time, which results in a fixed amount of revenue to be recognized by us.  Our storage agreements require our customers to make minimum payments based on the volume of storage capacity made available to the customer under the agreement, which results in a fixed amount of revenue to be recognized by us.  We refer to the fixed amount of revenue recognized pursuant to our terminaling services agreements as being “firm commitments.”  Revenue recognized in excess of firm commitments and revenue recognized based solely on the volume of product distributed or injected are referred to as “variable.”  Our revenue was as follows (in thousands):

The amount of revenue recognized as “firm commitments” based on the remaining contractual term of the terminaling services agreements that generated “firm commitments” for the three months ended March 31, 2013 was as follows (in thousands):

RECENT DEVELOPMENTS

On December 20, 2012, we acquired a 42.5% interest in Battleground Oil Specialty Terminal Company LLC, or BOSTCO, from Kinder Morgan Energy Partners, L.P., or Kinder Morgan, for approximately $79 million.  BOSTCO is a new black oil terminal under construction on the Houston Ship Channel designed for the handling of residual fuel, feedstocks, distillates and other black oils.  The initial phase of the BOSTCO project involves construction of 50 storage tanks with approximately 6.1 million barrels of storage capacity at an estimated cost of $425 million.  The BOSTCO facility’s docks will benefit from one of the deepest vessel drafts and nearest access points in the Houston Ship Channel and will be well positioned to capitalize on increasing exports of petroleum related products. The BOSTCO facility is scheduled to begin commercial operation in the fourth quarter of 2013.  Completion of the full 6.1 million barrels of storage capacity and related infrastructure is scheduled for the first half of 2014.  Our investment in BOSTCO was approved by Morgan Stanley, who indirectly controls our general partner. Morgan Stanley’s approval was based on the specific facts and circumstances of the BOSTCO project and the structure of our investment, and is not indicative of whether Morgan Stanley will approve any other acquisition or investment that we may propose in the future.

On April 16, 2013, we announced a distribution of $0.64 per unit for the period from January 1, 2013 through March 31, 2013, payable on May 7, 2013 to unitholders of record on April 30, 2013.

LIQUIDITY AND CAPITAL RESOURCES

TransMontaigne Partners also released the following statements regarding its current liquidity and capital resources:

·                  On December 20, 2012, in connection with our purchase of a 42.5% interest in BOSTCO, we amended our credit facility to increase our maximum borrowing line of credit from $250 million to $350 million. The amendment also provided us with the ability to make up to $225 million of investments in BOSTCO and to make an additional $75 million of “other permitted joint venture investments”, which may also include additional investments in BOSTCO. The credit facility became effective March 9, 2011 and expires on March 9, 2016.  At March 31, 2013, our outstanding borrowings were $246 million.

·                  We have funded our investments in the BOSTCO construction project utilizing additional borrowings under our credit facility.  Upon completion of the initial phase of the project, we expect our share of the total payments for the project to be approximately $183 million.  At March 31, 2013, our investment in the BOSTCO project was approximately $136 million.

·                  Management and the board of directors of our general partner have approved additional investments in BOSTCO and expansion capital projects at our existing terminals that currently are, or will be, under construction with estimated completion dates that extend through the first quarter of 2014. At March 31, 2013, the remaining expenditures to complete the approved additional investments and expansion capital projects are estimated to be approximately $50 million. We expect to fund our future investments and expansion capital expenditures with additional borrowings under our credit facility.

·                  Our primary liquidity needs are to fund our working capital requirements, distributions to unitholders, approved investments, approved capital projects and approved future expansion, development and acquisition opportunities. We expect to initially fund our approved investments, approved capital projects and our approved future expansion, development and acquisition opportunities with additional borrowings under our credit facility. After initially funding these expenditures with borrowings under our credit facility, we may raise funds through additional equity offerings and debt financings. The proceeds of such equity offerings and debt financings may then be used to reduce our outstanding borrowings under our credit facility.

ATTACHMENT B

DISTRIBUTABLE CASH FLOW

The following summarizes our distributable cash flow for the period indicated (in thousands):

Distributable cash flow is not a computation based upon generally accepted accounting principles.  The amounts included in the computation of our distributable cash flow are derived from amounts separately presented in our consolidated financial statements, notes thereto and “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations”  in our Quarterly Report on Form 10-Q for the three months ended March 31, 2013, which was filed with the Securities and Exchange Commission on May 7, 2013.   Distributable cash flow should not be considered in isolation or as an alternative to net earnings or operating income, as an indication of our operating performance, or as an alternative to cash flows from operating activities as a measure of liquidity.  Distributable cash flow is not necessarily comparable to similarly titled measures of other companies. Distributable cash flow is presented here because it is a widely accepted financial indicator used to compare partnership performance.   We believe that this measure provides investors an enhanced perspective of the operating performance of our assets, the cash we are generating and our ability to make distributions to our unitholders and our general partner.
