charcoal materials. The loan was collateralized by building and land use right of Tantech Bamboo with maximum guaranteed amount up to approximately $4.0 million (RMB25,960,000). The loan was also guaranteed by two related parties, Lishui Jiuanju Commercial Trade Co., Ltd. (“LJC”), and Forasen Group Co., Ltd., one unrelated third party, Zhejiang Meifeng Tea Industry Co., Ltd., and three related individuals, Zhengyu Wang, Chairman of the Board and previous CEO of the Company, his wife, Yefang Zhang, and his relative, Aihong Wang. The loan was fully repaid upon its maturity in July 2021.
On July 2, 2021, Tantech Charcoal entered into a short-term loan agreement with Bank of China (Lishui Branch) to borrow approximately $2.6 million (RMB 17,080,000) for six months with fixed annual interest rate of 4.65%. The purpose of the loan was for purchasing bamboo charcoal materials. The loan was collateralized by building and land use right of Tantech Bamboo with maximum guaranteed amount up to approximately $4.0 million (RMB25,960,000). The loan was also guaranteed by two related parties, Lishui Jiuanju Commercial Trade Co., Ltd. (“LJC”), and Forasen Group Co., Ltd., one unrelated third party, Zhejiang Meifeng Tea Industry Co., Ltd., and other three related individuals, Zhengyu Wang, Chairman of the Board and previous CEO of the Company, his wife, Yefang Zhang, and his relative, Aihong Wang.
Although we currently do not have any material unused sources of liquidity, giving effect to the foregoing bank loans and other financing activities, we believe that our currently available working capital should be adequate to sustain our operations at our current levels through at least for the next twelve months. We will consider additional borrowing or public offering based on our working capital needs and capital expenditure requirements. There is no seasonality of our borrowing activities.
Statutory Reserves
Under PRC regulations, all our subsidiaries in the PRC may pay dividends only out of their accumulated profits, if any, determined in accordance with PRC GAAP. In addition, these companies are required to set aside at least 10% of their after-tax net profits each year, if any, to fund the statutory reserves until the balance of the reserves reaches 50% of their registered capital. The statutory reserves are not distributable in the form of cash dividends to the Company and can be used to make up cumulative prior year losses.
Restrictions on net assets also include the conversion of local currency into foreign currencies, tax withholding obligations on dividend distributions, the need to obtain State Administration of Foreign Exchange approval for loans to a non-PRC consolidated entity. We did not have these restrictions on our net assets as of June 30, 2021 and December 31, 2020. We are also a party to certain debt agreements that are secured with pledges on our real property in Tianning located in Lishui, China. But such debt agreements do not restrict our net assets and instead only impose restrictions on the pledged property.
The following table provides the amount of our statutory reserves, the amount of restricted net assets, consolidated net assets, and the amount of restricted net assets as a percentage of consolidated net assets, as of June 30, 2021 and December 31, 2020.
| | | | | | | |
| | As of | | As of | |
| | June 30, | | December 31, | |
| | 2021 | | 2020 | |
Statutory Reserves | | $ | 6,437,506 | | $ | 6,437,506 | |
Total Restricted Net Assets | | $ | 6,437,506 | | $ | 6,437,506 | |
Consolidated Net Assets | | $ | 102,493,776 | | $ | 99,491,388 | |
Restricted Net Assets as Percentage of Consolidated Net Assets | | | 6.3 | % | | 6.5 | % |
Total restricted net assets accounted for approximately 6.3% and 6.5% of our consolidated net assets as of June 30, 2021 and December 31, 2020 respectively. As our subsidiaries usually set aside only 10% of after-tax net profits each year to fund the statutory reserves and are not required to fund the statutory reserves when they incur losses, we believe the potential impact of such restricted net assets on our liquidity is limited.
Capital Expenditures
We had capital expenditures of $5,086 and $9,524 for the six months ended June 30, 2021 and 2020, respectively, for the purchasing of equipment in connection with our business activities.
We expect that our capital expenditures will increase in the future as our business continues to develop and expand. We have used cash generated from our subsidiaries’ operations to fund our capital commitments in the past and anticipate using such funds and proceeds received from our offerings through issuance of common stocks and other sources to fund capital expenditure commitments in the future.
