processing natural gas at its processing plants ; fractionating and marketing recovered ngls ; providing compression services ; providing crude oil and condensate transportation and terminal services ; providing condensate stabilization services ; and providing brine disposal services . the partnership typically gathers or transports gas owned by others through its facilities for a fee . the partnership also buys natural gas from a producer , plant or shipper at either a fixed discount to a market index or a percentage of the market index , then transports and resells the natural gas at the same market index . story_separator_special_tag the vex pipeline is a 60-mile multi-grade crude oil pipeline with a current capacity of approximately 90,000 bbls/d . other vex assets at the destination of the pipeline include an eight-bay truck unloading terminal , 200,000 barrels of above-ground storage and rights to barge loading docks . issuance of the partnership 's common units equity distribution agreement . in november 2014 , the partnership entered into an equity distribution agreement ( the “ bmo eda ” ) with bmo capital markets corp. and certain other sales agents to sell up to $ 350.0 million in aggregate gross sales of the partnership 's common units from time to time through an “ at the market ” equity offering program . the partnership may also sell common units to any sales agent as principal for the sales agent 's own account at a price agreed upon at the time of sale . the partnership has no obligation to sell any of the common units under the bmo eda and may at any time suspend solicitation and offers under the bmo eda . for the year ended december 31 , 2015 the partnership sold an aggregate of 1.3 million common units under the bmo eda , generating proceeds of approximately $ 24.4 million ( net of approximately $ 0.3 million of commissions ) . the partnership used the net proceeds for general partnership purposes . as of december 31 , 2015 , approximately $ 317.0 million of common units remain available to be issued under the bmo eda . private placement of common units . on october 29 , 2015 , the partnership issued 2,849,100 common units with an offering price of $ 17.55 per common unit to our subsidiary for aggregate consideration of approximately $ 50.0 million in a private placement transaction , which the partnership used for general partnership purposes . issuance of preferred units . on january 7 , 2016 , the partnership issued an aggregate of 50,000,000 series b cumulative convertible preferred units representing limited partner interests , ( the “ preferred units ” ) to enfield holdings , l.p.
