Our common units represent limited partner interests, which give the holders thereof the right to participate in distributions and to exercise the other rights or privileges available to them under our Sixth Amended and Restated Agreement of Limited Partnership (as amended from time to time, the "Partnership Agreement"). We are managed by our general partner, Enterprise GP. In accordance with our Partnership Agreement, capital accounts are maintained for our limited partners. The capital account provisions of our Partnership Agreement incorporate principles established for U.S. Federal income tax purposes and are not comparable to the equity amounts presented in our consolidated financial statements prepared in accordance with GAAP. Earnings and cash distributions are allocated to holders of our common units in accordance with their respective percentage interests. 2013 Shelf. In June 2013, we filed with the U.S. Securities and Exchange Commission ("SEC") a new universal shelf registration statement (the "2013 Shelf") that replaced our prior universal shelf registration statement filed with the SEC in July 2010 (the "2010 Shelf"). The 2013 Shelf allows (and the prior 2010 Shelf allowed) Enterprise Products Partners L.P. and EPO (each on a standalone basis) to issue an unlimited amount of equity and debt securities, respectively. We used the 2013 Shelf and 2010 Shelf to facilitate the following securities offerings:
 | We used the 2010 Shelf to issue 18,400,000 common units to the public (including an over-allotment amount of 2,400,000 common units) at an offering price of $27.28 per unit in February 2013, which generated net cash proceeds of $486.6 million. In addition, EPO issued $2.25 billion of unsecured senior notes during 2013 using the 2010 Shelf.
 | We used the 2013 Shelf to issue 18,400,000 common units to the public (including an over-allotment amount of 2,400,000 common units) at an offering price of $31.03 per unit in November 2013, which generated net cash proceeds of $553.0 million.
 | We used the 2013 Shelf to issue $4.75 billion of unsecured senior notes during 2014.
 | We used the 2013 Shelf to issue $2.5 billion of unsecured senior notes during 2015 (see Note 8).
At-the-Market ("ATM") Program. On July 1, 2015, we filed a registration statement with the SEC covering the issuance of up to $1.92 billion of our common units in amounts, at prices and on terms to be determined by market conditions and other factors at the time of such offerings. Pursuant to the ATM program, we may sell common units under an equity distribution agreement between Enterprise Products Partners L.P. and certain broker-dealers from time-to-time by means of ordinary brokers' transactions through the NYSE at market prices, in block transactions or as otherwise agreed to with the broker-dealer parties to the agreement. The new registration statement was declared effective on August 3, 2015 and replaced our prior registration statement with respect to the ATM program, which was filed with the SEC in October 2013 and covered the issuance of up to $1.25 billion of our common units. Immediately prior to the effectiveness of the new registration statement, we had the capacity to issue additional common units under the ATM program up to an aggregate sales price of $424.6 million (after giving effect to sales of common units previously made under the ATM program). During 2015, we issued 25,520,424 common units under our ATM program for aggregate gross cash proceeds of $825.4 million, resulting in total net cash proceeds of $817.4 million. This includes 3,225,057 common units sold in March 2015 to a privately held affiliate of EPCO, which generated gross proceeds of $100 million. During 2014, we issued 1,590,334 common units under our ATM program for aggregate gross cash proceeds of $58.3 million, resulting in total net cash proceeds of $57.7 million. During 2013, we issued 15,249,378 common units under our ATM for aggregate gross cash proceeds of $460.4 million, resulting in total net cash proceeds of $456.3 million. Following the effectiveness of the new registration statement and after taking into account the aggregate sales price of common units sold under our ATM program through December 31, 2015, we have the capacity to issue additional common units under our ATM program up to an aggregate sales price of $1.86 billion. DRIP and EUPP. We also have registration statements on file with the SEC collectively authorizing the issuance of up to 140,000,000 of our common units in connection with a distribution reinvestment plan ("DRIP"). The DRIP provides unitholders of record and beneficial owners of our common units a voluntary means by which they can increase the number of our common units they own by reinvesting the quarterly cash distributions they receive from us into the purchase of additional new common units. Activity under our DRIP for the last three years was as follows: 12,413,351 common units issued during 2015, which generated net cash proceeds of $359.8 million; 9,480,407 common units issued during 2014, which generated net cash proceeds of $321.3 million; and 10,024,828 common units issued during 2013, which generated net cash proceeds of $287.6 million. Privately held affiliates of EPCO reinvested $100 million through the DRIP in each of 2015 and 2014 (this amount being a component of the net cash proceeds presented for each period). After taking into account the number of common units issued under the DRIP through December 31, 2015, we have the capacity to issue an additional 15,067,998 common units under this plan. In addition to the DRIP, we have registration statements on file with the SEC authorizing the issuance of up to 8,000,000 of our common units in connection with an employee unit purchase plan ("EUPP"). Activity under our EUPP for the last three years was as follows: 380,562 common units issued during 2015, which generated net cash proceeds of $11.4 million; 273,820 common units issued during 2014, which generated net cash proceeds of $9.8 million; and 283,426 common units issued during 2013, which generated net cash proceeds of $8.5 million. After taking into account the number of common units issued under the EUPP through December 31, 2015, we may issue an additional 6,772,506 common units under this plan. The net cash proceeds we received from the issuance of common units during the year ended December 31, 2015 were used to temporarily reduce amounts outstanding under EPO's commercial paper program and revolving credit facilities and for general company purposes. Registration Rights Agreement. In order to fund the equity consideration paid in Step 1 of the Oiltanking acquisition (see Note 12), we issued 54,807,352 common units to OTA on October 1, 2014 in a transaction exempt from the registration requirements of the Securities Act of 1933, as amended, pursuant to Section 4(a)(2) thereof, and we granted OTA registration rights with respect to these common units under a Registration Rights Agreement between us and OTA (the "Registration Rights Agreement"). The Registration Rights Agreement provides that, subject to the terms and conditions set forth therein, at any time after the earlier of (i) 90 days after October 1, 2014 and (ii) the execution of definitive agreements to acquire (through merger or otherwise) all or substantially all of the Oiltanking common units not owned by Enterprise or its affiliates, OTA may request that we prepare and file a registration statement to permit and otherwise facilitate the public resale of all or a portion of the 54,807,352 Enterprise common units that OTA owns. Our obligation to OTA to effect such transactions is limited to five registration statements and underwritten offerings. Completion of Oiltanking Acquisition. In accordance with the merger agreement and Oiltanking's partnership agreement, the merger was submitted to a vote of Oiltanking's common unitholders, with the required majority of unitholders (including our ownership interests) voting to approve the merger on February 13, 2015. Upon approval of the merger, a total of 36,827,517 of our common units were issued to Oiltanking's former public unitholders. Step 2 of the acquisition was accounted for in accordance with ASC Topic 810, Consolidations – Overall – Changes in Parent's Ownership Interest in a Subsidiary. Since we had a controlling financial interest in Oiltanking before and after completion of Step 2, the increase in our ownership interest in Oiltanking was accounted for as an equity transaction with no gain or loss recognized. Step 2 represented our acquisition of the noncontrolling interests in Oiltanking; therefore, approximately $1.4 billion of noncontrolling interests attributable to Oiltanking were reclassified to limited partners' equity to reflect the February 2015 issuance of 36,827,517 new common units. Class B Units. In connection with the TEPPCO merger in October 2009, a privately held affiliate of EPCO exchanged a portion of its TEPPCO units (based on a 1.24 exchange ratio) for 9,040,862 of our Class B units in lieu of receiving common units. The Class B units automatically converted into the same number of common units on the date immediately following the payment date for the sixteenth regular quarterly distribution following the closing date of the TEPPCO merger. The Class B units were entitled to vote together with our common units as a single class on partnership matters and generally had the same rights and privileges as our common units, except that the Class B units were not entitled to receive regular quarterly cash distributions until they automatically converted into an equal number of common units on August 8, 2013. Treasury Units. In December 1998, we announced a common unit repurchase program whereby we, together with certain affiliates, intended to repurchase up to 4,000,000 of our common units. A total of 2,763,200 common units were repurchased under this program; however, no repurchases have been made since 2002. As of December 31, 2015, we and our affiliates could repurchase up to 1,236,800 additional common units under this program. A total of 2,009,970 restricted common unit awards granted to employees of EPCO vested and converted to common units during the year ended December 31, 2015. Of this amount, 683,954 were sold back to us by employees to cover related withholding tax requirements. The total cost of these treasury unit purchases was approximately $33.6 million. We cancelled such treasury units immediately upon acquisition. See Note 13 for additional information regarding our equity-based awards. Two-for-One Split of Limited Partner Units. In July 2014, we announced that our general partner approved a two-for-one split of our common units. The common unit split was completed on August 21, 2014 by distributing one additional common unit for each common unit outstanding (to holders of record as of the close of business on August 14, 2014). All per unit amounts and number of Enterprise units outstanding in this annual report are presented on a post-split basis. Accumulated Other Comprehensive Loss Accumulated other comprehensive income (loss) primarily reflects the effective portion of the gain or loss on derivative instruments designated and qualified as cash flow hedges. Gain or loss amounts related to cash flow hedges recorded in accumulated other comprehensive income (loss) are reclassified to earnings in the same period(s) in which the underlying hedged forecasted transactions affect earnings. If it becomes probable that a forecasted transaction will not occur, the related net gain or loss in accumulated other comprehensive income (loss) is immediately reclassified into earnings. The following tables present the components of accumulated other comprehensive income (loss) as reported on our Consolidated Balance Sheets at the dates indicated:
|  | Gains (Losses) on Cash Flow Hedges |  |  |  |  |  |  |

Noncontrolling Interests Noncontrolling interests represent third party equity ownership interests in our consolidated subsidiaries. We reclassified approximately $1.4 billion of noncontrolling interests to limited partners' equity in connection with completing Step 2 of the Oiltanking acquisition in February 2015. Cash distributions paid in the first quarter of 2015 to the limited partners of Oiltanking other than EPO and its subsidiaries are presented as amounts paid to noncontrolling interests. In February 2015, we formed a joint venture involving our Panola NGL Pipeline with affiliates of Anadarko Petroleum Corporation ("Anadarko"), DCP Midstream Partners, LP ("DCP") and MarkWest Energy Partners, L.P. ("MarkWest"). We continue to serve as operator of the Panola Pipeline and own 55% of the member interests in the joint venture. Affiliates of Anadarko, DCP and MarkWest own the remaining 45% member interests, with each holding a 15% interest. The Panola Pipeline transports mixed NGLs from points near Carthage, Texas to Mont Belvieu, Texas and supports the Haynesville and Cotton Valley oil and gas production areas. The following table presents additional information regarding noncontrolling interests as presented on our Consolidated Balance Sheets at the dates indicated:

In November 2010, we completed our merger with Enterprise GP Holdings L.P. (the "Holdings Merger"). In connection with the Holdings Merger, a privately held affiliate of EPCO agreed to temporarily waive the regular cash distributions it would otherwise receive from us with respect to a certain number of our common units it owns (the "Designated Units"). Distributions paid to partners during calendar years 2013, 2014 and 2015 excluded 47,400,000, 45,120,000 and 35,380,000 Designated Units, respectively. The temporary distribution waiver expired in November 2015; therefore, distributions to be paid, if any, during calendar year 2016 will include all common units owned by the privately held affiliates of EPCO.
