Our operating cash flows can also be impacted by changes in our NGLs and natural gas inventory balances, which are driven primarily by commodity prices, supply, demand and the operation of our assets. 2022 vs. 2021 - Cash flows from operating activities, before changes in operating assets and liabilities, increased $214.5 million due primarily to higher net income resulting from higher realized commodity prices, net of hedging, and higher average fee rates in our Natural Gas Gathering and Processing segment and higher exchange services in our Natural Gas Liquids segment.
Our operating cash flows can also be impacted by changes in our inventory balances, which are driven primarily by commodity prices, supply, demand and the operation of our assets. 2023 vs. 2022 - Cash flows from operating activities, before changes in operating assets and liabilities increased $1.1 billion for the year ended December 31, 2023, compared with the same period in 2022, due primarily to higher operating income resulting from higher volumes from increased production and higher average fee rates in our Natural Gas Gathering and Processing segment, higher exchange services in our Natural Gas Liquids segment, higher transportation and storage services in our Natural Gas Pipelines segment and an increase due to the impact of the Magellan Acquisition in our Refined Products and Crude segment; and insurance proceeds received from the Medford settlement.

The change is due primarily to changes in risk management assets and liabilities, which include the gains associated with the settlements of forward-starting interest rate swaps in 2022 and changes in the fair value of risk-management assets and liabilities; accounts receivable resulting from the timing of receipt of cash from customers and NGLs and natural gas in inventory, both of which vary from period to period and with changes in commodity prices; offset partially by changes in accounts payable, which also vary from period to period with changes in commodity prices, and from the timing of payments to vendors, suppliers and other third parties and changes in other assets and liabilities.
