Current PRC laws and regulations place certain restrictions on foreign ownership of companies that engage in internet businesses, including the provision of online video and online advertising services. Specifically, foreign ownership in an internet content provider or other value-added telecommunication service providers may not exceed 50%. The Group conducts its operations in China principally through contractual arrangements among Giganology Shenzhen, its wholly owned PRC subsidiary, and Shenzhen Xunlei and its shareholders. Shenzhen Xunlei holds the licenses and permits necessary to conduct its resource discovery network, online advertising, online games and related businesses in China and hold various operating subsidiaries that conduct a majority of its operations in China. The Company conducts all of its operations in China through, Shenzhen Xunlei, a variable interest entity, which it consolidates as a result of a series contractual arrangements enacted. If the Company had direct ownership of Shenzhen Xunlei, it would be able to exercise its rights as a shareholder to effect changes in the board of directors of Shenzhen Xunlei, which in turn could effect changes at the management level, subject to any applicable fiduciary obligations. However, under the current contractual arrangements, it relies on Shenzhen Xunlei and its shareholders’ performance of their contractual obligations to exercise effective control. In addition, its operating contract with Shenzhen Xunlei has a term of ten years, which is subject to Giganology Shenzhen’s unilateral termination right. None of Shenzhen Xunlei or its shareholders may terminate the contracts prior to the expiration date.

Further, the Group believes that the contractual arrangements among Giganology Shenzhen, Shenzhen Xunlei and its shareholders are in compliance with PRC law and are legally enforceable. However, the Chinese government may issue from time to time new laws or new interpretations on existing laws to regulate this industry. Regulatory risk also encompasses the interpretation by the tax authorities of current tax laws, and the Group’s legal structure and scope of operations in the PRC, which could be subject to further restrictions resulting in limitations on the Company’s ability to conduct business in the PRC. The PRC government may also require the Company to restructure the Group’s operations entirely if it finds that its contractual arrangements do not comply with applicable laws and regulations. Furthermore, it could revoke the Group’s business and operating licenses, require it to discontinue or restrict its operations, restrict its right to collect revenues, block its website, require it to restructure its operations, impose additional conditions or requirements with which the Group may not be able to comply, or take other regulatory or enforcement actions against the Group that could be harmful to its business. The imposition of any of these penalties may result in a material and adverse effect on the Group’s ability to conduct the Group’s business. In addition, if the imposition of any of these penalties causes the Group to lose the rights to direct the activities of the VIE and its subsidiaries or the right to receive their economic benefits, the Group would no longer be able to consolidate the VIE. The Group does not believe that any penalties imposed or actions taken by the PRC Government would result in the liquidation of the Company, Giganology Shenzhen or Shenzhen Xunlei.

As stated above, Shenzhen Xunlei holds assets that are important to the operation of the Group’s business, including patents for proprietary technology, related domain names and trademarks. If Shenzhen Xunlei or its subsidiaries falls into bankruptcy and all or part of its assets become subject to liens or rights of third-party creditors, the Group may be unable to conduct its business activities in China, which could have a material adverse effect on the Group’s future financial position, results of operations or cash flows. However, the Group believes this is a normal business risk many companies face. The Group will continue to closely monitor the financial conditions of Shenzhen Xunlei and its subsidiaries.

Shenzhen Xunlei and its subsidiaries’ assets comprise both recognized and unrecognized revenue-producing assets. The recognized revenue-producing assets include intangible assets, purchased property and equipment. The balances of these assets held by the VIE and its subsidiaries are included in “property and equipment, net” and “intangible assets, net” in the consolidated balance sheet and specifically in the VIE table on the following page. The unrecognized revenue-producing assets mainly consist of license, patents, trademarks, and domain names which are not recorded in the financial statement as they did not meet the recognition criteria set in ASC 350-30-25. The licenses stated above primarily consist of licenses that grant the VIE and its subsidiaries the right to produce and broadcast internet, radio, and television programs. One of them is the ICP licenses as described in note 1.

As of December 31, 2020, Shenzhen Xunlei and its subsidiaries held patents granted in the PRC and in the United States. Presently, certain patent applications are being examined by the State Intellectual Property Office of the PRC.

As of December 31, 2020, Shenzhen Xunlei and its subsidiaries have applied to register trademarks, of which the Company has received registered trademarks in different applicable trademark categories including registered with World Intellectual Property Organization.

Foreign exchange risk

The Group’s financing activities are denominated mainly in USD. The RMB is not freely convertible into foreign currencies. Remittances of foreign currencies into the PRC and exchange of foreign currencies into the RMB require approval by foreign exchange administrative authorities and certain supporting documentation. The State Administration for Foreign Exchange, under the authority of the People’s Bank of China, controls the conversion of RMB into other currencies. The revenues and expenses of the Company’s subsidiaries, consolidated VIE and its subsidiaries are generally denominated in RMB and their assets and liabilities are denominated in RMB.

Concentration of customer risk

The top 10 customers accounted for 23%, 31% and 38% of the net revenues for the years ended December 31, 2018, 2019 and 2020, respectively.

Credit risk

As of December 31, 2019 and 2020, substantially all of the Group’s cash and cash equivalents, restrict cash and short-term investments were held at reputable financial institutions in the jurisdictions where the Group and its subsidiaries are located. The Group believes that it is not exposed to unusual risks as these financial institutions have high credit quality. The Group has not experienced any losses on its deposits of cash and cash equivalents, restricted cash and short-term investments.

Prior to entering into sales agreements, the Group performs ongoing credit assessments of its customers, taking into account their financial position, credit history and other factors such as current market conditions. Further, the Group has not experienced any significant bad debts with respect to its accounts receivable for the years ended December 31, 2019 and 2020, the addition of allowance for doubtful accounts for the year ended December 31, 2018 was mainly arisen from the cloud computing service to a customer.

29. Certain risks and concentration (Continued)

Credit risk (Continued)

The Group is exposed to credit risk in relation to other assets comprised of due from related parties and other receivables, which are typically unsecured. In evaluating the collectability of the balances, the Group considered various factors, including the related parties and third parties’ repayment history and their credit-worthiness. An allowance for credit losses is made when collection of the full amount is no longer probable.

Restricted net assets

Relevant PRC laws and regulations permit payments of dividends by the Company’s subsidiaries, VIE and VIE’s subsidiaries in China only out of their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. In addition, the Company’s subsidiaries, VIE and VIE’s subsidiaries in China are required to make certain appropriation of net after-tax profits or increase in net assets to the statutory surplus fund (see note 2(bb)) prior to payment of any dividends. As a result of these and other restrictions under PRC laws and regulations, the Company’s subsidiaries, VIE and VIE’s subsidiaries in China are restricted in their ability to transfer their net assets to the Company in terms of cash dividends, loans or advances, which restricted portion amounted to USD 168,493,000 as of December 31, 2020, or 58% of the Company's total consolidated net assets. Even though the Company currently does not require any such dividends, loans or advances from the PRC subsidiaries, VIE and VIE’s subsidiaries for working capital and other funding purposes, the Company may in the future require additional cash resources from the Company’s subsidiaries, VIE and a VIE’s subsidiaries in China due to changes in business conditions, to fund future acquisitions and development, or merely to declare and pay dividends to make distributions to shareholders.
