commercial customers, large and small, and has an allocation based on fair value of real estate properties as determined by our NAV calculation of 28.8% office, 35.0% retail which is primarily grocery-anchored, 21.0% industrial, and 15.2% multi-family.
We believe that our cash on-hand, anticipated net offering proceeds, proceeds from our line of credit, and other financing and disposition activities should be sufficient to meet our anticipated future acquisition, operating, debt service, distribution and redemption requirements.
Cash Flows. The following table summarizes our cash flows for the following periods:
| | | | | | | | | | |
| | For the Three Months Ended March 31, | | | | |
(in thousands) | | 2021 | | 2020 | | $ Change | |
Total cash provided by (used in): | | | | | | | | | | |
Operating activities | | $ | 7,659 | | $ | 7,455 | | $ | 204 | |
Investing activities | | | (7,704) | | | (65,290) | | | 57,586 | |
Financing activities | | | 5,913 | | | 78,947 | | | (73,034) | |
Net increase in cash, cash equivalents and restricted cash | | $ | 5,868 | | $ | 21,112 | | $ | (15,244) | |
Net cash provided by operating activities remained fairly consistent in total for the three months ended March 31, 2021, compared to the same period in 2020.
Net cash used in investing activities decreased by approximately $57.6 million for the three months ended March 31, 2021, compared to the same period in 2020, primarily due to (i) an increase in net disposition proceeds of $46.2 million due to proceeds received in 2021 related to the sale of one retail property and one industrial property, as compared to the sale of one retail outparcel during the corresponding period in 2020; (ii) a decrease in acquisition activity during the three months ended March 31, 2021 of $7.3 million; (iii) lower capital expenditure activity during the three months ended March 31, 2021 of $3.3 million; and (iv) an increase in principal collections on debt-related investments due to the $2.4 million repayment of a debt-related investment during the three months ended March 31, 2021.
Net cash provided by financing activities decreased by approximately $73.0 million for the three months ended March 31, 2021, compared to the same period in 2020, primarily due to the net repayment of the line of credit during the three months ended March 31, 2021 of $52.0 million and due to a $39.2 million decrease in net offering activity from our DST Program and public offering. These drivers were partially offset by a $17.9 million decrease in public offering and OP Unit redemptions.
Capital Resources and Uses of Liquidity
In addition to our cash and cash equivalents balances available, our capital resources and uses of liquidity are as follows:
Line of Credit and Term Loans. As of March 31, 2021, we had an aggregate of $975.0 million of commitments under our unsecured credit agreements, including $450.0 million under our line of credit and $525.0 million under our two term loans. As of that date, we had: (i) $54.0 outstanding under our line of credit; and (ii) $525.0 million outstanding under our term loans. The weighted-average effective interest rate across all of our unsecured borrowings is 3.11%, which includes the effect of the interest rate swap agreements related to $500.0 million in borrowings under our term loans.
The unused and available portions under our line of credit were $396.0 million and $260.2 million, respectively. Our $450.0 million line of credit matures in January 2023, and may be extended pursuant to two six-month extension options, subject to certain conditions, including the payment of extension fees. Our $325.0 million term loan matures in January 2024, with no extension option available. Our $200.0 million term loan matures in February 2022, and may be extended pursuant to two one-year extension options, subject to certain conditions, including the payment of an extension fee. Our line of credit borrowings are available for general corporate purposes, including but not limited to the refinancing of other debt, payment of redemptions, acquisition and operation of permitted investments. Refer to “Note 3 to the Condensed Consolidated Financial Statements” for additional information regarding our line of credit and term loans.
In July 2017, the Financial Conduct Authority (“FCA”) that regulates LIBOR announced it intends to stop compelling banks to submit rates for the calculation of LIBOR. As a result, the Federal Reserve Board and the Federal Reserve Bank of New York organized the Alternative Reference Rates Committee (“ARRC”), which identified the Secured Overnight Financing Rate ("SOFR") as its preferred alternative rate for LIBOR in derivatives and other financial contracts. We are not able to predict when LIBOR will cease to be available or when there will be sufficient liquidity in the SOFR markets. Any changes adopted by the FCA or other governing bodies
