Advance payments received under long‑term terminaling services agreements. We have long‑term terminaling services agreements with certain of our customers that provide for advance minimum payments. We recognize the advance minimum payments as revenue either on a straight‑line basis over the term of the respective agreements or when services have been provided based on volumes of product distributed. At September 30, 2016 and December 31, 2015, we have received advance minimum payments in excess of revenue recognized under these long‑term terminaling services agreements resulting in a liability of approximately $0.5 million and $0.6 million, respectively.

Deferred revenue—ethanol blending fees and other projects. Pursuant to agreements with our customers, we agreed to undertake certain capital projects that primarily pertain to providing ethanol blending functionality at certain of our Southeast terminals. Upon completion of the projects, our customers have paid us lump‑sum amounts that will be recognized as revenue on a straight‑line basis over the remaining term of the agreements. At September 30, 2016 and December 31, 2015, we have unamortized deferred revenue of approximately $1.8 million and $2.2 million, respectively, for completed projects. During the three months ended September 30, 2016 and 2015, we recognized revenue on a straight‑line basis of approximately $0.1 million and $0.4 million, respectively, for completed projects.
