Total stockholder dividends paid by Principal Life to its parent for the three months ended March 31, 2021, were $300.0 million, all of which was extraordinary and approved by the Commissioner. As of March 31, 2021, we had $2,800.2 million of cash and liquid assets held in our holding companies and other subsidiaries, which is available for corporate purposes. This includes assets in excess of targeted statutory capital ratios and immediate working capital needs. Corporate balances held in foreign holding companies meet the indefinite reinvestment exception.
Operations. Our primary consolidated cash flow sources are premiums from insurance products, pension and annuity deposits, asset management fee revenues, administrative services fee revenues, income from investments and proceeds from the sales or maturity of investments. Cash outflows consist primarily of payment of benefits to policyholders and beneficiaries, income and other taxes, current operating expenses, payment of dividends to policyholders, payments in connection with investments acquired, payments made to acquire subsidiaries, payments relating to policy and contract surrenders, withdrawals, policy loans, interest payments and repayment of short-term debt and long-term debt. Our investment strategies are generally intended to provide adequate funds to pay benefits without forced sales of investments. For a discussion of our investment objectives and strategies, see “Investments.”
Cash Flows. Cash flow activity, as reported in our consolidated statements of cash flows, provides relevant information regarding our sources and uses of cash. The following discussion of our operating, investing and financing portions of the cash flows excludes cash flows attributable to the separate accounts.
Net cash provided by operating activities was $140.8 million and $1,589.1 million for the three months ended March 31, 2021 and 2020, respectively. Our insurance business typically generates positive cash flows from operating activities, as premiums collected from our insurance products and income received from our investments exceed acquisition costs, benefits paid, redemptions and operating expenses. These positive cash flows are then invested to support the obligations of our insurance and investment products and required capital supporting these products. Our cash flows from operating activities are affected by the timing of premiums, fees and investment income received and benefits and expenses paid. The decrease in cash provided by operating activities was primarily due to fluctuations in receivables and payables associated with the timing of settlements in 2021 as compared to 2020. Additionally, increases in net income were offset in part by proceeds from real estate sold in 2020 with no corresponding activity in 2021.
Net cash used in investing activities was $1,019.2 million and $912.7 million for the three months ended March 31, 2021 and 2020, respectively. The increase in cash used in investing activities was primarily due to increased net purchases of mortgage loans and lower Chile direct financing lease maturities in in 2021 as compared to 2020. The increase was offset in part by lower net purchases of available-for-sale securities in 2021 as compared to 2020.
Net cash provided by financing activities was $32.1 million and $290.4 million for the three months ended March 31, 2021 and 2020, respectively. The decrease in cash provided by financing activities was primarily due to lower investment contract deposits, net of withdrawals, in 2021 as compared to 2020.
