Exhibit 2.1

Description of Securities

We are a Cayman Islands exempted company limited by shares and our affairs are governed by our memorandum and articles of association, as amended and restated from time to time and the Companies Act (Revised) of the Cayman Islands, which is referred to as the Companies Act below, and the common law of the Cayman Islands.

As approved by our shareholders at an extraordinary general meeting of the shareholders of our company held on August 10, 2023, we subdivided each of our issued and unissued ordinary shares into 50 ordinary shares with par value being changed from US$0.0001 per share to US$0.000002 per share, effective immediately. As approved by our shareholders on April 11, 2024, we subdivided each of our issued and unissued ordinary shares into two ordinary shares with par value being changed from US$0.000002 per share to US$0.000001 per share, effective immediately. Following the First Share Split, the Second Share Split and as of the date hereof, our authorized share capital is US$500,000 divided into 500,000,000,000 ordinary shares with par value of US$0.000001 each. The shares are presented on a retroactive basis to reflect the First Share Split, the Second Share Split and the nominal share issuance.

We have adopted the second amended and restated memorandum and articles of association and our authorized share capital was changed into US$500,000 divided into 500,000,000,000 shares with par value of US$0.000001 each comprising of 480,000,000,000 class A ordinary shares with par value of US$0.000001 each and 20,000,000,000 class B ordinary shares with par value of US$0.000001 each. The following are summaries of material provisions of our second amended and restated memorandum and articles of association and the Companies Act insofar as they relate to the material terms of our ordinary shares that became effective on August 27, 2024.

ORDINARY SHARES

Objects of Our Company. Under our second amended and restated memorandum and articles of association, the objects of our company are unrestricted, and we have the full power and authority to carry out any object not prohibited by the law of the Cayman Islands.

General. All of our issued and outstanding ordinary shares are fully paid and non-assessable. Certificates representing the ordinary shares are issued in registered form. Our shareholders who are nonresidents of the Cayman Islands may freely hold and vote their shares.

Dividends. The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors subject to the Companies Act and our second amended and restated memorandum and articles of association.

Conversion. Each Class B ordinary share is convertible into one (1) Class A ordinary share at any time at the option of the holder thereof. The right to convert shall be exercisable by the holder of the Class B ordinary share delivering a written notice to the Company that such holder elects to convert a specified number of Class B ordinary share into Class A ordinary share. In no event shall Class A ordinary share be convertible into Class B ordinary share. Any conversion of Class B ordinary shares into Class A ordinary shares pursuant to our second amended and restated memorandum and articles of association shall be effected by means of the re-designation and re-classification of each relevant Class B ordinary share as a Class A ordinary share. Any future issuances of Class B ordinary shares may be dilutive to holders of Class A ordinary shares. The conversion of Class B ordinary shares might have impact on holders of Class A ordinary shares, including dilution and reduction in the aggregate voting power of holders of Class A ordinary shares, as well as the potential increase in the relative voting power if any holder of Class B ordinary shares retains its shares.

Voting Rights. Holders of our Class A ordinary shares and our Class B ordinary shares shall, at all times, vote together as one class on all matters submitted to a vote by our shareholders at any general meeting of our company. Each Class A ordinary share shall be entitled the holder thereof to one (1) vote on all matters subject to vote at general meetings of our company, and each Class B ordinary share shall be entitled the holder thereof to twenty (20) votes on all matters subject to a vote at general meetings of our company. At any general meeting a resolution put to the vote of the meeting shall be decided by a poll. A poll shall be taken in such manner as the chairman of the meeting directs, and the result of the poll shall be deemed to be the resolution of the meeting.

A quorum required for a meeting of shareholders consists of at least one or more shareholders present in person or by proxy or, if a corporation or other non-natural person, by its duly authorized representative, who hold shares which carry in aggregate not less than one-third of all votes attaching to all issued and outstanding shares of our company and entitled to vote at such general meeting. An annual general meeting may (but shall not be obliged to) hold in each year. The chairman or the directors (acting by a resolution of the board) may call general meetings, and they shall on a shareholders’ requisition forthwith proceed to an extraordinary general meeting. Advance notice of at least seven calendar days is required for the convening of any general meeting.

An ordinary resolution to be passed by the shareholders requires the affirmative votes of a simple majority of the votes cast by such shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy or, in the case of corporations, by their duly authorized representatives, at a general meeting, while a special resolution requires the affirmative votes of no less than two-thirds of the votes cast by such shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy or, in the case of corporations, by their duly authorized representatives, at a general meeting of which notice specifying the intention to propose the resolution as a special resolution has been duly given. A special resolution is required for important matters such as a change of name or making changes to our second amended and restated memorandum and articles of association. Holders of the ordinary shares may effect certain changes by ordinary resolution, including increasing our authorized share capital, consolidating and dividing all or any of our share capital into shares of larger amount than our existing shares, and canceling any shares that, at the date of the passing of the resolution, have not been taken or agreed to be taken by any person and diminish the amount of its share capital by the amount of the shares so canceled.

Transfer of Shares. Subject to the restrictions of our second amended and restated memorandum and articles of association set out below, as applicable, any of our shareholders may transfer all or any of his or her ordinary shares by an instrument of transfer in the usual or common form or any other form approved by our board of directors.

Our board of directors may, in its sole discretion, decline to register any transfer of any ordinary share which is not fully paid up or on which we have a lien. Our directors may also decline to register any transfer of any ordinary share unless (a) the instrument of transfer is lodged with us, accompanied by the certificate for the ordinary shares to which it relates and such other evidence as our board of directors may reasonably require to show the right of the transferor to make the transfer; (b) the instrument of transfer is in respect of only one class of shares; (c) the instrument of transfer is properly stamped, if required; (d) in the case of a transfer to joint holders, the number of joint holders to whom the ordinary share is to be transferred does not exceed four; and (e) a fee of such maximum sum as the Nasdaq Global Market may determine to be payable, or such lesser sum as our board of directors may from time to time require, is paid to us in respect thereof.

If our directors refuse to register a transfer they shall, within three calendar months after the date on which the instrument of transfer was lodged with our company, send to each of the transferor and the transferee notice of such refusal. The registration of transfers may, on ten (10) calendar days’ notice being given by advertisement in such one or more newspapers, by electronic means or by any other means in accordance with any notice required of the Nasdaq Global Market, be suspended and the register closed at such times and for such periods as our board of directors may from time to time determine, provided, however, that the registration of transfers shall not be suspended nor the register closed for more than 30 calendar days in any calendar year.

Liquidation. If our company shall be wound up, and the assets available for distribution amongst the shareholders shall be insufficient to repay the whole of the share capital, such assets shall be distributed so that, as nearly as may be, the losses shall be borne by the shareholders in proportion to the par value of the shares held by them. If in a winding up the assets available for distribution amongst the shareholders shall be more than sufficient to repay the whole of the share capital at the commencement of the winding up, the surplus shall be distributed amongst the shareholders in proportion to the par value of the shares held by them at the commencement of the winding up subject to a deduction from those shares in respect of which there are monies due, of all monies payable to us for unpaid calls or otherwise.

Calls on Shares and Forfeiture of Shares. Our board of directors may from time to time make calls upon shareholders for any amounts unpaid on their shares, and each shareholder shall (subject to receiving at least fourteen (14) calendar days’ notice specifying the time or times of payment) pay to us at the time or times so specified the amount called on such shares. The shares that have been called upon and remain unpaid on the specified time are subject to forfeiture.

Redemption, Repurchase and Surrender of Shares. Subject to the provisions of the Companies Act, we may issue shares on terms that are subject to redemption, at our option or at the option of the holders, on such terms and in such manner as may be determined by our board of directors, before the issue of such shares, or by an ordinary resolution of our shareholders. Our company may also repurchase any of our shares provided that the manner and terms of such purchase have been approved by our board of directors or by an ordinary resolution of our shareholders. Under the Companies Act, the redemption or repurchase of any share may be paid out of our company’s profits or out of the proceeds of a fresh issue of shares made for the purpose of such redemption or repurchase, or out of capital (including share premium account and capital redemption reserve) if the company can, immediately following the date on which the payment is proposed to be made, pay its debts as they fall due in the ordinary course of business. In addition, under the Companies Act, no such share may be redeemed or repurchased (a) unless it is fully paid up, (b) if such redemption or repurchase would result in there being no shares outstanding, or (c) if the company has commenced liquidation. In addition, our company may accept the surrender of any fully paid share for no consideration.

Variations of Rights of Shares. Whenever the capital of our company is divided into different classes the rights attached to any such class may, subject to any rights or restrictions for the time being attached to any class, only be materially and adversely varied with the consent in writing of the holders of at least two-thirds of the issued shares of that class or with the sanction of an ordinary resolution passed at a separate meeting of the holders of the shares of that class.

Inspection of Books and Records. Holders of our ordinary shares will have no general right under Cayman Islands law to inspect or obtain copies of our list of shareholders or our corporate records (other than copies of our memorandum and articles of association and register of mortgages and charges, and any special resolutions passed by our shareholders). Under Cayman Islands law, the names of our current directors can be obtained from a search conducted at the Registrar of Companies in the Cayman Islands. See “Where You Can Find Additional Information.”

Changes in Capital. Our shareholders may from time to time by ordinary resolution:

Subject to the Companies Act and our second amended and restated memorandum and articles of association with respect to matters to be dealt with by ordinary resolution, we may, by special resolution, reduce our share capital and any capital redemption reserve in any manner authorized by the Companies Act.

Issuance of Additional Shares. Our second amended and restated memorandum and articles of association authorizes our board of directors to issue additional ordinary shares from time to time as our board of directors shall determine, to the extent there are available authorized but unissued shares.

Our second amended and restated memorandum and articles of association authorizes our board of directors to establish from time to time one or more series of convertible redeemable preferred shares and to determine, with respect to any series of convertible redeemable preferred shares, the terms and rights of that series, including:

The issuance of convertible redeemable preferred shares may be used as an anti-takeover device without further action on the part of the shareholders. Issuance of these shares may dilute the voting power of holders of ordinary shares.

Anti-Takeover Provisions. Some provisions of our second amended and restated memorandum and articles of association may discourage, delay or prevent a change of control of our company or management that shareholders may consider favorable, including provisions that:

However, under Cayman Islands law, our directors may only exercise the rights and powers granted to them under our second amended and restated memorandum and articles of association for a proper purpose and for what they believe in good faith to be in the best interests of our company.

Exempted Company. We are an exempted company with limited liability under the Companies Act. The Companies Act distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except that an exempted company:

“Limited liability” means that the liability of each shareholder is limited to the amount unpaid by the shareholder on the shares of the company (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil).

Register of Members. Under the Companies Act, we must keep a register of members and there should be entered therein:

Under Cayman Islands law, the register of members of our company is prima facie evidence of the matters set out therein (i.e. the register of members will raise a presumption of fact on the matters referred to above unless rebutted) and a member registered in the register of members is deemed as a matter of Cayman Islands law to have legal title to the shares as set against its name in the register of members. Upon the completion of this offering, the register of members will be immediately updated to record and give effect to the issue of shares by us to the depositary (or its nominee) as the depositary. Once our register of members has been updated, the shareholders recorded in the register of members will be deemed to have legal title to the shares set against their name.

If the name of any person is incorrectly entered in or omitted from our register of members, or if there is any default or unnecessary delay in entering on the register the fact of any person having ceased to be a member of our company, the person or member aggrieved (or any member of our company or our company itself) may apply to the Grand Court of the Cayman Islands for an order that the register be rectified, and the Court may either refuse such application or it may, if satisfied of the justice of the case, make an order for the rectification of the register.

DIFFERENCES IN CORPORATE LAW

The Companies Act is derived, to a large extent, from the older Companies Acts of England but does not follow recent English statutory enactments and, accordingly, there are significant differences between the Companies Act and the current Companies Act of England. In addition, the Companies Act differs from laws applicable to United States corporations and their shareholders. Set forth below is a summary of certain significant differences between the provisions of the Companies Act applicable to us and the laws applicable to companies incorporated in the State of Delaware.

Mergers and Similar Arrangements. The Companies Act permits mergers and consolidations between Cayman Islands companies and between Cayman Islands companies and non-Cayman Islands companies. For these purposes, (a) “merger” means the merging of two or more constituent companies and the vesting of their undertaking, property and liabilities in one of such companies as the surviving company and (b) a “consolidation” means the combination of two or more constituent companies into a consolidated company and the vesting of the undertaking, property and liabilities of such companies to the consolidated company. In order to effect such a merger or consolidation, the directors of each constituent company must approve a written plan of merger or consolidation, which must then be authorized by (i) a special resolution of the shareholders of each constituent company and (ii) such other authorization, if any, as may be specified in such constituent company’s articles of association. The written plan of merger or consolidation must be filed with the Registrar of Companies of the Cayman Islands together with a declaration as to the solvency of the consolidated or surviving company, a list of the assets and liabilities of each constituent company and an undertaking that a copy of the certificate of merger or consolidation will be given to the members and creditors of each constituent company and that notification of the merger or consolidation will be published in the Cayman Islands Gazette. Court approval is not required for a merger or consolidation effected in compliance with these statutory procedures.

Separate from the statutory provisions relating to mergers and consolidations, the Companies Act also contains statutory provisions that facilitate the reconstruction and amalgamation of companies by way of schemes of arrangement, provided that the arrangement is approved by (i) 75% in value of the members or class of members or (ii) a majority in number representing 75% in value of the creditors or class of creditors, in each case depending on the circumstances, as are present at a meeting called for such purpose and thereafter sanctioned by the Grand Court of the Cayman Islands. Whilst a dissenting member has the right to express to the court his view that the transaction for which approval is being sought would not provide the members with a fair value for their shares, it can be expected that the court would approve the transaction if it is satisfied that (i) the company is not proposing to act illegally or beyond the scope of our corporate authority and the statutory provisions as to majority vote have been complied with, (ii) the members have been fairly represented at the meeting in question, (iii) the transaction is such as a businessman would reasonable approve and (iv) the transaction is not one that would more properly be sanctioned under some other provisions of the Companies Act or that would amount to a “fraud on the minority”.

The Companies Act also contains a statutory power of compulsory acquisition which may facilitate the “squeeze out” of dissentient minority shareholder upon a tender offer. When a tender offer is made and accepted by holders of 90% of the shares affected within four months, the offeror may, within a two-month period commencing on the expiration of such four month period, require the holders of the remaining shares to transfer such shares to the offeror on the terms of the offer. An objection can be made to the Grand Court of the Cayman Islands, but it is unlikely to succeed in the case of an offer which has been so approved unless there is evidence of fraud, bad faith or collusion.

If an arrangement and reconstruction by way of scheme of arrangement is thus approved and sanctioned, or if a tender offer is made and accepted in accordance with the foregoing statutory procedures, a dissenting shareholder would have no rights comparable to appraisal rights, which would otherwise ordinarily be available to dissenting shareholders of Delaware corporations, providing rights to receive payment in cash for the judicially determined value of the shares.

Shareholders’ Suits. In principle, we will normally be the proper plaintiff to sue for a wrong done to us as a company, and as a general rule a derivative action may not be brought by a minority shareholder. However, based on English authorities, which would in all likelihood be of persuasive authority in the Cayman Islands, the Cayman Islands courts can be expected to follow and apply common law principles (namely the rule in Foss v. Harbottle and the exceptions thereto) so that a non-controlling shareholder may be permitted to commence a class action against or derivative actions in the name of the company to challenge actions where:

Indemnification of Directors and Executive Officers and Limitation of Liability. Cayman Islands law does not limit the extent to which a company’s memorandum and articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against civil fraud or the consequences of committing a crime.

Our second amended and restated memorandum and articles of association permit indemnification of directors and officers for all actions, proceedings, losses, costs, charges, expenses, damages or liabilities incurred in or about the conduct of our business or affairs (including as a result of any mistake of judgment) or in the execution or discharge of his duties, powers, authorities or discretions as such unless such losses or damages arise from dishonesty, fraud or willful default of such directors or officers. This standard of conduct is generally the same as permitted under the Delaware General Corporation Law for a Delaware corporation. In addition, we intend to enter into indemnification agreements with our directors and senior executive officers that will provide such persons with additional indemnification beyond that provided in our second amended and restated memorandum and articles of association.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers or persons controlling us under the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Directors’ Fiduciary Duties. Under Delaware corporate law, a director of a Delaware corporation has a fiduciary duty to the corporation and its shareholders. This duty has two components: the duty of care and the duty of loyalty. The duty of care requires that a director act in good faith, with the care that an ordinarily prudent person would exercise under similar circumstances. Under this duty, a director must inform himself of, and disclose to shareholders, all material information reasonably available regarding a significant transaction. The duty of loyalty requires that a director acts in a manner he or she reasonably believes to be in the best interests of the corporation. He or she must not use his or her corporate position for personal gain or advantage. This duty prohibits self-dealing by a director and mandates that the best interest of the corporation and its shareholders take precedence over any interest possessed by a director, officer or controlling shareholder and not shared by the shareholders generally. In general, actions of a director are presumed to have been made on an informed basis, in good faith and in the honest belief that the action taken was in the best interests of the corporation. However, this presumption may be rebutted by evidence of a breach of one of the fiduciary duties. Should such evidence be presented concerning a transaction by a director, the director must prove the procedural fairness of the transaction, and that the transaction was of fair value to the corporation.

As a matter of Cayman Islands law, a director of a Cayman Islands company is in the position of a fiduciary with respect to the company and therefore it is considered that he owes the following duties to the company—a duty to act in good faith in the best interests of the company, a duty not to make a personal profit based on his or her position as director (unless the company permits him to do so) and a duty not to put himself in a position where the interests of the company conflict with his or her personal interest or his or her duty to a third party and a duty to exercise powers for the purpose for which such powers were intended. A director of a Cayman Islands company owes to the company a duty to act with skill and care. It was previously considered that a director needs not exhibit in the performance of his or her duties a greater degree of skill than may reasonably be expected from a person of his or her knowledge and experience. However, English and Commonwealth courts have moved towards an objective standard with regard to the required skill and care and these authorities are likely to be followed in the Cayman Islands.

Shareholder Action by Written Consent. Under the Delaware General Corporation Law, a corporation may eliminate the right of shareholders to act by written consent by amendment to its certificate of incorporation. Cayman Islands law and our second amended and restated memorandum and articles of association provide that our shareholders may approve corporate matters by way of a unanimous written resolution signed by or on behalf of each shareholder who would have been entitled to vote on such matter at a general meeting without a meeting being held.

Shareholder Proposals. Under the Delaware General Corporation Law, a shareholder has the right to put any proposal before the annual meeting of shareholders; provided that it complies with the notice provisions in the governing documents. A special meeting may be called by the board of directors or any other person authorized to do so in the governing documents, but shareholders may be precluded from calling special meetings.

The Companies Act provides shareholders with only limited rights to requisition a general meeting, and does not provide shareholders with any right to put any proposal before a general meeting. However, these rights may be provided in a company’s articles of association. Our second amended and restated memorandum and articles of association allow our shareholders holding shares which carry in aggregate not less than one-third of all votes attaching to all issued and outstanding shares of our company to requisition an extraordinary meeting of the shareholders, in which case the directors are obliged to call such meeting and to put the resolutions so requisitioned to a vote at such meeting. However, our second amended and restated memorandum and articles of association do not provide our shareholders with any right to put any proposals before annual general meetings or extraordinary general meetings not called by such shareholders.

As an exempted Cayman company, we are not obliged by law to call shareholders’ annual general meetings. Our second amended and restated memorandum and articles of association provides that we may (but shall not be obliged to) in each year to hold a general meeting as our annual general meeting, and shall specify the meeting as such in the notice calling it.

Cumulative Voting. Under the Delaware General Corporation Law, cumulative voting for elections of directors is not permitted unless the corporation’s certificate of incorporation specifically provides for it. Cumulative voting potentially facilitates the representation of minority shareholders on a board of directors since it permits the minority shareholder to cast all the votes to which the shareholder is entitled on a single director, which increases the shareholder’s voting power with respect to electing such director. There are no prohibitions in relation to cumulative voting under Cayman Islands law, but our second amended and restated memorandum and articles of association do not provide for cumulative voting. As a result, our shareholders are not afforded any less protections or rights on this issue than shareholders of a Delaware corporation.

Removal of Directors. Under the Delaware General Corporation Law, a director of a corporation with a classified board of directors may be removed only for cause with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. Under our second amended and restated memorandum and articles of association, directors may be removed from office by the affirmative vote of two-thirds (2/3) of the directors then in office (except with regard to the removal of the chairman, who may be removed from office by the affirmative vote of all directors), or by an ordinary resolution (except with regard to the removal of the chairman, who may be removed from office by a special resolution).

Transactions with Interested Shareholders. The Delaware General Corporation Law contains a business combination statute applicable to Delaware corporations whereby, unless the corporation has specifically elected not to be governed by such statute by amendment to its certificate of incorporation, it is prohibited from engaging in certain business combinations with an “interested shareholder” for three years following the date that such person becomes an interested shareholder. An interested shareholder generally is a person or a group who or which owns or owned 15% or more of the target’s outstanding voting stock within the past three years. This has the effect of limiting the ability of a potential acquirer to make a two-tiered bid for the target in which all shareholders would not be treated equally. The statute does not apply if, among other things, prior to the date on which such shareholder becomes an interested shareholder, the board of directors approves either the business combination or the transaction which resulted in the person becoming an interested shareholder. This encourages any potential acquirer of a Delaware corporation to negotiate the terms of any acquisition transaction with the target’s board of directors.

Cayman Islands law has no comparable statute. As a result, we cannot avail ourselves of the types of protections afforded by the Delaware business combination statute. However, although Cayman Islands law does not regulate transactions between a company and its significant shareholders, it does provide that such transactions must be entered into bona fide in the best interests of the company and not with the effect of constituting a fraud on the minority shareholders.

Dissolution; Winding up. Under the Delaware General Corporation Law, unless the board of directors approves the proposal to dissolve, dissolution must be approved by shareholders holding 100% of the total voting power of the corporation. Only if the dissolution is initiated by the board of directors may it be approved by a simple majority of the corporation’s outstanding shares. Delaware law allows a Delaware corporation to include in its certificate of incorporation a supermajority voting requirement in connection with dissolutions initiated by the board of directors. Under Cayman Islands law, a company may be wound up by either an order of the courts of the Cayman Islands or by a special resolution of its members or, if the company is unable to pay its debts as they fall due, by an ordinary resolution of its members. The court has authority to order winding up in a number of specified circumstances including where it is, in the opinion of the court, just and equitable to do so.

Under the Companies Act and our second amended and restated memorandum and articles of association, our company may be dissolved, liquidated or wound up voluntarily by a special resolution of our shareholders.

Variation of Rights of Shares. Under the Delaware General Corporation Law, a corporation may vary the rights of a class of shares with the approval of a majority of the outstanding shares of such class, unless the certificate of incorporation provides otherwise. Under our second amended and restated memorandum and articles of association, if our share capital is divided into more than one class of shares, the rights attached to any such class may, subject to any rights or restrictions for the time being attached to any class, only be materially and adversely varied with the consent in writing of the holders of at least two-thirds of the issued shares of that class or with the sanction of an ordinary resolution passed at a separate meeting of the holders of the shares of that class.

Amendment of Governing Documents. Under the Delaware General Corporation Law, a corporation’s governing documents may be amended with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. Under the Companies Act and our second amended and restated memorandum and articles of association, our second amended and restated memorandum and articles of association may only be amended by a special resolution.

Rights of Non-resident or Foreign Shareholders. There are no limitations imposed by our second amended and restated memorandum and articles of association on the rights of non-resident or foreign shareholders to hold or exercise voting rights on our shares. In addition, there are no provisions in our second amended and restated memorandum and articles of association that require our company to disclose shareholder ownership above any particular ownership threshold.
