The jump in **Q3 2024** was primarily driven by **strong account growth** and a **significant increase in margin borrowing**, which expanded the segregated cash portfolio for regulatory purposes. Additionally, increases in **customer credit balances**—rising by about **$11.6 billion** over the nine months—further contributed to this increase.  **[0001381197-24-000140_ibkr_8ka-20240930.htm:2]** **[0001381197-24-000135_ibkr-8k_20240930er.htm:3]** **[0001381197-24-000143_ibkr-20240930x10q.htm:2]** **[IBKR_3402841_2]** **[0001381197-24-000143_ibkr-20240930x10q.htm:69]** 

What drove the jump in Cash - segregated for regulatory purposes in Q3 2024?

In Q3 2024, **Interactive Brokers Group's** total assets increased significantly due to **growth in margin lending** (which drove up customer receivables), an **increase in cash segregated for regulatory purposes** (reflecting higher customer credit balances), higher activity in **securities borrowed and resale agreements**, and an increase in **financial instruments owned at fair value** (indicating more investments in marketable securities).  **[IBKR_3402841_3]** **[0001381197-24-000140_ibkr_8ka-20240930.htm:2]** **[0001381197-24-000135_ibkr-8k_20240930er.htm:3]** 

What contributed to the significant rise in Total assets in Q3 2024?

The documents do not provide a definitive explanation for the spike in **short-term borrowings** to **33 in Q3 2024**. While they note that the borrowings increased significantly—from **$17 million at year-end 2023** to **$33 million on September 30, 2024**—no specific reasons are provided. That said, potential explanations could include factors such as **operational needs, liquidity management, or funding requirements**.  **[0001381197-24-000140_ibkr_8ka-20240930.htm:2]** **[0001381197-24-000135_ibkr-8k_20240930er.htm:3]** **[0001381197-24-000143_ibkr-20240930x10q.htm:2]** 

Why did Short-term borrowings spike to 33 in Q3 2024?

The surge in Q3 2024 was primarily driven by a **significant increase in stocks**, which rose from **$1,023 million** to **$1,850 million**, and a notable increase in **U.S. and foreign government securities**, which grew from **$39 million** to **$948 million**. Although there was a decline in options from **$354 million** to **$119 million**, the larger gains in stocks and government securities more than offset this decrease, leading to the overall increase in total financial instruments owned.  **[0001381197-24-000143_ibkr-20240930x10q.htm:2]** **[0001381197-24-000143_ibkr-20240930x10q.htm:28]**

The sharp spike in operating cash flow in Q3 2024 was driven by several key changes in operating assets and liabilities. **Customer credit balances increased by $11.6 billion** and **securities loaned rose by $5.5 billion**, both significantly boosting cash inflows. Additionally, there was a **$4.3 billion decrease in investments held for regulatory purposes**, which further added to the operating cash flow. These positive impacts were partially offset by a **$11.5 billion increase in customer margin loans**, but the overall effect was a substantial rise in operating cash flow.  **[0001381197-24-000143_ibkr-20240930x10q.htm:69]** **[0001381197-24-000143_ibkr-20240930x10q.htm:4]** 

What drove the sharp spike in operating cash flow in Q3 2024?

The turnaround in operating cash flow for Q1 2024 was primarily driven by a **$6.1 billion decrease** in securities segregated for regulatory purposes and a **$2.9 billion increase** in securities loaned, both of which significantly improved cash inflows. These positive factors were partially offset by a **$6.9 billion increase** in customer margin loans and a **$1.2 billion increase** in securities purchased under agreements to resell, but the net effect was a substantial swing from negative operating cash flow in Q1 2023 to a positive **$1,683 million** in Q1 2024.  **[0001381197-24-000097_ibkr-20240331x10q.htm:60]** **[0001381197-24-000097_ibkr-20240331x10q.htm:3]** 

What factors contributed to the turnaround in operating cash flow in Q1 2024?

The noticeable decline in Q2 2024’s operating cash flow was mainly due to an offsetting factor—**a significant increase in customer margin loans**. Although certain changes in operating assets (for example, **a decrease of $7.1 billion in securities segregated for regulatory purposes** and **an increase of $4.3 billion in securities loaned**) helped improve cash flow, these gains were largely counterbalanced by the jump in customer margin loans, which rose by **$10.8 billion** in 2024 compared to **$3.2 billion** in 2023, thereby reducing the net cash provided from operations.  **[0001381197-24-000124_ibkr-20240630x10q.htm:68]** **[0001381197-24-000124_ibkr-20240630x10q.htm:3]** 

Why did operating cash flow decline noticeably in Q2 2024?

The documents do not provide any detailed information regarding a substantial increase in approximated free cash flow in Q3 2024. They only explain the drivers for the increased net cash used in investing activities for that period.  **[0001381197-23-000149_ibkr-20230930x10q.htm:3]** **[0001381197-24-000143_ibkr-20240930x10q.htm:69]** **[0001381197-24-000143_ibkr-20240930x10q.htm:4]**
