We believe that the terms and provisions of our related party agreements are fair to us; however, such agreements and transactions may not be as favorable to us as we could have obtained from unaffiliated third parties. Relationship with EPCO and Affiliates We have an extensive and ongoing relationship with EPCO and its privately held affiliates (including Enterprise GP, our general partner), which are not a part of our consolidated group of companies. At September 30, 2025, EPCO and its privately held affiliates (including Dan Duncan LLC and certain Duncan family trusts) beneficially owned the following limited partner interests in us:
Total Number of Limited Partner Interests Held | Percentage of Common Units Outstanding
702,247,078 common units | 32.5%
Of the total number of Partnership common units held by EPCO and its privately held affiliates, 59,976,464 have been pledged as security under the separate credit facilities of EPCO and its privately held affiliates at September 30, 2025. These credit facilities contain customary and other events of default, including defaults by us and other affiliates of EPCO. An event of default, followed by a foreclosure on the pledged collateral, could ultimately result in a change in ownership of these units and affect the market price of the Partnership’s common units. The Partnership and Enterprise GP are both separate legal entities apart from each other and apart from EPCO and its other affiliates, with assets and liabilities that are also separate from those of EPCO and its other affiliates. EPCO and its privately held affiliates use cash on hand and cash distributions they receive from us and other investments to fund their other activities and to meet their respective debt obligations, if any. During the nine months ended September 30, 2025 and 2024, we paid EPCO and its privately held affiliates cash distributions totaling $1.1 billion and $1.1 billion, respectively. We have no employees. All of our administrative and operating functions are provided either by employees of EPCO (pursuant to the ASA) or by other service providers. We and our general partner are parties to the ASA. The following table presents our related party costs and expenses attributable to the ASA with EPCO for the periods indicated:
| For the Three Months Ended September 30, |  | For the Nine Months Ended September 30,
| 2025 |  | 2024 |  | 2025 |  | 2024
Operating costs and expenses | $ | 364 |  |  | $ | 323 |  |  | $ | 1,079 |  |  | $ | 956 |
General and administrative expenses | 33 |  |  | 37 |  |  | 101 |  |  | 111 |
Total costs and expenses | $ | 397 |  |  | $ | 360 |  |  | $ | 1,180 |  |  | $ | 1,067 |
We lease office space from privately held affiliates of EPCO. For the three months ended September 30, 2025 and 2024, we recognized $6 million and $7 million, respectively, of related party operating lease expense in connection with these office space leases. For the nine months ended September 30, 2025 and 2024, we recognized $18 million and $17 million, respectively, of related party operating lease expense in connection with these office space leases.
