Supplement to the Definitive Proxy Statement

On December 31, 2025, Columbus Acquisition Corp (the “Company”) filed a definitive proxy statement with the Securities and Exchange Commission (the “SEC”) in connection with its solicitation of proxies for an extraordinary general meeting of shareholders to be held on January 16, 2026, at 9:00 a.m., Eastern Time (the “Extraordinary General Meeting”). At the Extraordinary General Meeting, it is proposed, among the others, that the Company amend its current charter to provide that the Company has until January 22, 2026 to complete a business combination, and may elect to extend the period to consummate a business combination up to twelve times, each by an additional one-month extension, for a total of up to twelve months to January 22, 2027.

In connection with the Extraordinary General Meeting, the Company has determined to amend and supplement the Definitive Proxy Statement to provide information about certain material U.S. federal income tax considerations for shareholders with respect to the exercise of these redemption rights in this current report on Form 8-K.

There is no change to the location, the record date or proposals to be acted upon at the Extraordinary General Meeting.

AMENDMENT AND SUPPLEMENT TO THE DEFINITIVE PROXY STATEMENT

The following disclosures in this Current Report on Form 8-K supplement, and should be read in conjunction with, the disclosures contained in the Company’s definitive proxy statement, including any amendments or supplements thereto (the “Definitive Proxy Statement”), filed with the Securities and Exchange Commission (the “SEC”) on December 31, 2025, which in turn should be read in its entirety. To the extent the information set forth herein differs from or updates information contained in the Definitive Proxy Statement, the information set forth herein shall supersede or supplement the information in the Definitive Proxy Statement. All other information in the Definitive Proxy Statement remains unchanged.

The purpose of the supplemental disclosures is to provide information about certain material U.S. federal income tax considerations for shareholders with respect to the exercise of these redemption rights.

Terms used herein, unless otherwise defined, have the meanings set forth in the Definitive Proxy Statement.

U.S. Federal Income Tax Considerations

The following is a discussion of certain material U.S. federal income tax considerations for U.S. holders and Non-U.S. holders (each as defined below) of public shares (i) with respect to the Charter Amendment Proposal and (ii) whose public shares are redeemed for cash if the Charter Amendment Proposal is approved and the Charter Amendment is implemented. This discussion applies only to U.S. holders and Non-U.S. holders that hold public shares as “capital assets” within the meaning of Section 1221 of the Code (as defined below) (generally, property held for investment). This discussion is based on provisions of the Internal Revenue Code (the “Code”), Treasury Regulations promulgated thereunder (“Treasury Regulations”), rulings and other published positions of the Internal Revenue Service (the “IRS”) and judicial decisions, all as in effect as of the date hereof, and all of which are subject to change and differing interpretations, possibly with retroactive effect. Any such change or differing interpretation could affect the accuracy of the statements and conclusions set forth in this discussion. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax considerations described in this discussion. No advance ruling has been or will be sought from the IRS regarding any matter discussed below.

This discussion is for general information purposes only and does not purport to be a complete analysis of all of the U.S. federal income tax considerations that may be relevant to particular holders in light of their particular facts and circumstances, or to holders subject to special rules under the U.S. federal income tax laws, including, for example, but not limited to:

	●	our Sponsor, founders, officers or directors;

	●	banks and other financial institutions;

	●	mutual funds;

	●	insurance companies;

	●	brokers or dealers in securities, currencies or commodities;

	●	dealers or traders in securities subject to a mark-to-market method of accounting;

	●	regulated investment companies and real estate investment trusts;

	●	retirement plans, individual retirement accounts and other deferred accounts;

	●	tax-exempt organizations, governmental agencies, instrumentalities or other governmental organizations and pension funds;

	●	persons holding public shares as part of a “straddle,” hedge, constructive sale, or other integrated or conversion transaction or similar transaction;

	●	U.S. holders whose functional currency is not the U.S. dollar;

	●	Partnerships, other entities or arrangements classified as partnerships for U.S. federal income tax purposes, “S corporations,” or other pass-through entities for U.S. federal income tax purposes (or investors in such entities);

	●	expatriated entities subject to Section 7874 of the Code;

	●	persons required to accelerate the recognition of any item of gross income as a result of such income being recognized on an “applicable financial statement”;

	●	persons subject to any alternative minimum tax;

	●	persons subject to the applicable financial statement accounting rules of Section 451(b) of the Code;

	●	U.S. expatriates and former citizens or long-term residents of the United States;

	●	holders owning or treated as owning 5% or more of our public shares (by vote or value);

	●	grantor trusts; and

	●	controlled foreign corporations, passive foreign investment companies, and corporations that accumulate earnings to avoid U.S. federal income tax.

This discussion does not address any U.S. federal tax considerations other than those pertaining to the income tax (such as estate, gift or other non-income tax considerations) or any state, local or foreign income or non-income tax considerations. In addition, this discussion does not address any considerations arising under the unearned income Medicare contribution tax, or any considerations in respect of any withholding required pursuant to the Foreign Account Tax Compliance Act of 2010 (including the Treasury Regulations promulgated thereunder and intergovernmental agreements entered into in connection therewith and any laws, regulations or practices adopted in connection with any such agreement).

If a partnership (or other entity or arrangement classified as a partnership for U.S. federal income tax purposes) holds public shares, the U.S. federal income tax treatment of the partners in the partnership generally will depend upon the status of the partner, the activities of the partner and the partnership and certain determinations made at the partner level. Accordingly, partnerships and partners in partnerships holding public shares should consult their tax advisors as to the particular tax consequences to them of the redemption of public shares.

THE U.S. FEDERAL INCOME TAX TREATMENT OF THE EXERCISE OF REDEMPTION RIGHTS DISCUSSED HEREIN TO ANY PARTICULAR SHAREHOLDER WILL DEPEND ON THE SHAREHOLDER’S PARTICULAR TAX CIRCUMSTANCES. YOU ARE URGED TO CONSULT YOUR TAX ADVISOR REGARDING THE U.S. FEDERAL, STATE, LOCAL AND NON-U.S. INCOME AND OTHER TAX CONSEQUENCES TO YOU OF A REDEMPTION OF YOUR PUBLIC SHARES IN LIGHT OF YOUR PARTICULAR INVESTMENT OR TAX CIRCUMSTANCES.

Tax Treatment of Non-Redeeming Shareholders

A public shareholder that does not elect to redeem its public shares if the Charter Amendment Proposal is approved and the Charter Amendment is implemented will continue to own its public shares, and will not recognize any income, gain or loss for U.S. federal income tax purposes solely as a result of the Charter Amendment Proposal.

Tax Treatment of Redeeming Shareholders

Subject to the PFIC rules discussed below, in the event that a holder’s public shares are redeemed pursuant to the redemption provisions described in this proxy statement under “Proposal No. 1 — The Charter Amendment Proposal — Redemption Rights,” the treatment of the redemption for U.S. federal income tax purposes will depend on whether the redemption qualifies as a sale of public shares under Section 302 of the Code. If the redemption qualifies as a sale of public shares, the material U.S. federal income tax consequences to a U.S. holder (as defined below) generally will be as described below under the section entitled “U.S. Holders — Taxation of Redemption Treated as a Sale of Public Shares,” and the material U.S. federal income tax consequences to a Non-U.S. holder (as defined below) generally will be as described under the section entitled “Non-U.S. Holders — Taxation of Redemption Treated as a Sale of Public Shares.”

Whether a redemption of a holder’s public shares qualifies for sale treatment will depend largely on the total number of shares treated as held, directly, indirectly or constructively, by such redeemed holder before and after the redemption (including any shares treated as held by such holder under applicable constructive ownership rules, including any shares constructively owned by the holder as a result of owning public warrants) relative to all of our shares outstanding both before and after the redemption. The redemption of a holder’s public shares generally will be treated as a sale of public shares by such holder (rather than as a corporate distribution) under Section 302 of the Code if the redemption: (i) is “substantially disproportionate” with respect to the holder; (ii) results in a “complete termination” of the holder’s interest in us; or (iii) is “not essentially equivalent to a dividend” with respect to the holder. These tests are explained more fully below.

In determining whether any of the foregoing tests result in a redemption qualifying for sale treatment, a holder takes into account not only shares actually owned by the holder, but also shares that are constructively owned by the holder under certain attribution rules set forth in the Code. Among other things, a holder may constructively own, in addition to shares owned directly, shares owned by certain related individuals and entities in which the holder has an interest or that have an interest in such holder, as well as any shares that the holder has a right to acquire pursuant to the exercise of an option, which would generally include public shares that could be acquired pursuant to the exercise of the public warrants. In order to meet the substantially disproportionate test, the percentage of our outstanding voting shares actually and constructively owned by the holder immediately following the redemption of such holder’s public shares must, among other requirements, be less than 80% of the percentage of our outstanding voting shares actually and constructively owned by the holder immediately before the redemption (taking into account redemptions by other holders of public shares). There will be a complete termination of a holder’s interest if either (i) all of the shares actually and constructively owned by the holder are redeemed or (ii) all of the shares actually owned by the holder are redeemed and the holder is eligible to waive, and effectively waives in accordance with specific rules, the attribution of shares owned by certain family members and the holder does not constructively own any other shares. The redemption of public shares will not be essentially equivalent to a dividend if the redemption results in a “meaningful reduction” of the holder’s proportionate interest in us. Whether the redemption will result in a meaningful reduction in a holder’s proportionate interest in us will depend on the particular facts and circumstances. However, the IRS has indicated in a published ruling that even a small reduction in the proportionate interest of a small minority shareholder in a publicly held corporation who exercises no control over corporate affairs may constitute such a “meaningful reduction.”

If none of the foregoing tests is satisfied, then the redemption of a holder’s public shares will be treated as a corporate distribution to the redeemed holder and the material U.S. federal income tax consequences of the redemption to such holder that is a U.S. holder generally will be as described below under the section entitled “U.S. Holders — Taxation of Redemption Treated as a Distribution,” and the material U.S. federal income tax consequences of the redemption to such holder that is a Non-U.S. holder generally will be as described below under the section entitled “Non-U.S. Holders — Taxation of Redemption Treated as a Distribution.” After the application of those rules, any remaining tax basis of the holder in the redeemed public shares will be added to the holder’s adjusted tax basis in its remaining shares, or, if it has none, to the holder’s adjusted tax basis in its public warrants or possibly in other shares constructively owned by it.

A holder of public shares should consult its tax advisors as to the tax consequences of a redemption.

U.S. Holders

This section applies to “U.S. holders.” For purposes of this discussion, a “U.S. holder” means a beneficial owner of public shares that is, for U.S. federal income tax purposes:

●

an individual who is a citizen or resident of the United States;

●

a corporation (or other entity taxable as a corporation) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

●

an estate the income of which is subject to U.S. federal income tax regardless of its source; or

●

a trust, if (i) a court within the United States is able to exercise primary supervision over the administration of such trust and one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code) have the authority to control all substantial decisions of the trust or (ii) the trust validly elected to be treated as a United States person for U.S. federal income tax purposes.

Taxation of Redemption Treated as a Distribution

If the redemption of a U.S. holder’s public shares is treated as a distribution, as discussed above under the section entitled “Tax Treatment of Redeeming Shareholders,” then subject to the PFIC rules discussed below, such a distribution generally will constitute a dividend for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Such amount will be includable in gross income by such U.S. holder who actually or constructively receives the distribution in accordance with the U.S. Holder’s regular method of accounting for U.S. federal income tax purposes. Dividends will be taxable to a corporate U.S. holder at regular rates and will not be eligible for the dividends-received deduction generally allowed to domestic corporations in respect of dividends from other domestic corporations. Subject to the PFIC rules described below, distributions in excess of our current and accumulated earnings and profits will constitute a return of capital that will be first applied against and reduce (but not below zero) the U.S. holder’s adjusted tax basis in its public shares. Any remaining excess will be treated as gain recognized on the sale or other taxable disposition of the public shares and will be treated as described below under the section entitled “U.S. Holders — Taxation of Redemption Treated as a Sale of Public Shares.”

With respect to non-corporate U.S. holders, under tax laws currently in effect and subject to certain exceptions (including, but not limited to, dividends treated as investment income for purposes of investment interest deduction limitations), dividends generally will be taxed at the lower applicable long-term capital gains rate only if the public shares are readily tradable on an established securities market in the United States, the Company is not treated as a PFIC at the time the dividend was paid or in the preceding year and provided certain holding period requirements are met. It is unclear whether the redemption rights with respect to our public shares may suspend the running of the applicable holding period for this purpose.

Taxation of Redemption Treated as a Sale of Public Shares

If the redemption of a U.S. holder’s public shares is treated as a sale, as discussed above under the section entitled “Tax Treatment of Redeeming Shareholders,” then subject to the PFIC rules discussed below a U.S. holder generally will recognize capital gain or loss in an amount equal to the difference between the amount of cash received and the U.S. holder’s adjusted tax basis in the public shares redeemed. Any such capital gain or loss generally will be long-term capital gain or loss if the U.S. holder’s holding period for the public shares so disposed of exceeds one year. It is unclear, however, whether the redemption rights with respect to the public shares may suspend the running of the applicable holding period for this purpose. Long-term capital gains recognized by non-corporate U.S. holders are generally eligible to be taxed at preferential rates. The deductibility of capital losses is subject to limitations. U.S. holders who hold different blocks of public shares (public shares purchased or acquired on different dates or at different prices) should consult their tax advisors to determine how the above rules apply to them.

Passive Foreign Investment Company Rules

A foreign (i.e., non-U.S.) corporation will be classified as a PFIC for U.S. federal income tax purposes if either (i) at least 75% of its gross income in a taxable year, including its pro rata share of the gross income of any corporation in which it is considered to own at least 25% of the shares by value, is passive income or (ii) at least 50% of its assets in a taxable year (ordinarily determined based on fair market value and averaged quarterly over the year), including its pro rata share of the assets of any corporation in which it is considered to own at least 25% of the shares by value, are held for the production of, or produce, passive income. Passive income generally includes dividends, interest, rents and royalties (other than rents or royalties derived from the active conduct of a trade or business) and gains from the disposition of passive assets. The determination of whether a foreign corporation is a PFIC is made annually. Pursuant to a “startup exception,” a foreign corporation will not be a PFIC for the first taxable year the foreign corporation has gross income (the “startup year”) if (i) no predecessor of the foreign corporation was a PFIC; (ii) the foreign corporation satisfies the IRS that it will not be a PFIC for either of the first two taxable years following the startup year; and (iii) the foreign corporation is not in fact a PFIC for either of those years.

Based upon the composition of our income and assets, and upon a review of our financial statements, we believe that we likely will not be eligible for the startup exception and therefore likely have been a PFIC since our first taxable year. No assurances can be made with respect to our status as a PFIC for the current taxable year or any future taxable year.

Although our PFIC status is determined annually, an initial determination that our company is a PFIC will generally apply for subsequent years to a U.S. holder who held public shares or warrants while we were a PFIC, whether or not we meet the test for PFIC status in those subsequent years. If we are determined to be a PFIC for any taxable year (or portion thereof) that is included in the holding period of a U.S. holder of our public shares and the U.S. holder did not make either a timely and valid qualified electing fund (“QEF”) election for our first taxable year as a PFIC in which the U.S. holder held (or was deemed to hold) public shares, a QEF election along with a purging election, or a mark-to-market election, each as described below, such U.S. holder generally will be subject to special rules with respect to (i) any gain recognized by the U.S. holder on the sale or other disposition of its public shares (which may include gain realized by reason of transfer of public shares that would otherwise qualify as non-recognition transactions for U.S. federal income tax purposes) and (ii) any “excess distribution” made to the U.S. holder (generally, any distributions to such U.S. holder during a taxable year of the U.S. holder that are greater than 125% of the average annual distributions received by such U.S. holder in respect of the public shares during the three preceding taxable years of such U.S. holder or, if shorter, such U.S. holder’s holding period for the public shares).

Under these rules:

●

the U.S. holder’s gain or excess distribution will be allocated ratably over the U.S. holder’s holding period for the public shares;

●

the amount allocated to the U.S. holder’s taxable year in which the U.S. holder recognized the gain or received the excess distribution, or to the period in the U.S. holder’s holding period before the first day of our first taxable year in which we are a PFIC, will be taxed as ordinary income;

●

the amount allocated to other taxable years (or portions thereof) of the U.S. holder and included in its holding period will be taxed at the highest tax rate in effect for that year and applicable to the U.S. holder; and

●

an additional tax equal to the interest charge generally applicable to underpayments of tax will be imposed on the U.S. holder with respect to the tax attributable to each such other taxable year of the U.S. holder.

In general, if we are determined to be a PFIC, a U.S. holder may avoid the PFIC tax consequences described above in respect of our public shares by making a timely and valid QEF election (if eligible to do so) to include in income its pro rata share of our net capital gains (as long-term capital gain) and other earnings and profits (as ordinary income), on a current basis, in each case, whether or not distributed, in the taxable year of the U.S. holder in which or with which our taxable year ends. A U.S. holder generally may make a separate election to defer the payment of taxes on undistributed income inclusions under the QEF rules, but if deferred, any such taxes will be subject to an interest charge.

The QEF election is made on a shareholder-by-shareholder basis and, once made, can be revoked only with the consent of the IRS. A U.S. holder generally makes a QEF election by attaching a completed IRS Form 8621 (Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund), including the information provided in a PFIC Annual Information Statement, to a timely filed U.S. federal income tax return for the tax year to which the election relates. Retroactive QEF elections generally may be made only by filing a protective statement with such return and if certain other conditions are met or with the consent of the IRS. U.S. holders are urged to consult their tax advisors regarding the availability and tax consequences of a retroactive QEF election under their particular circumstances.

In order to comply with the requirements of a QEF election, a U.S. holder must receive a PFIC Annual Information Statement from us. If we determine we are a PFIC for any taxable year, upon written request, we will endeavor to provide to a U.S. holder such information as the IRS may require, including a PFIC Annual Information Statement, in order to enable the U.S. holder to make and maintain a QEF election, but there is no assurance that we will timely provide such required information. There is also no assurance that we will have timely knowledge of our status as a PFIC in the future or of the required information to be provided.

If a U.S. holder has made a QEF election with respect to our public shares, and the excess distribution rules discussed above do not apply to such shares (because of a timely QEF election for our first taxable year as a PFIC in which the U.S. holder holds (or is deemed to hold) such shares or a purge of the PFIC taint pursuant to a purging election, as described above), any gain recognized on the sale of our public shares generally will be taxable as capital gain and no additional tax or interest charge will be imposed under the PFIC rules. As discussed above, if we are a PFIC for any taxable year, a U.S. holder of our public shares that has made a QEF election will be currently taxed on its pro rata share of our earnings and profits, whether or not distributed for such year. A subsequent distribution of such earnings and profits that were previously included in income generally should not be taxable when distributed to such U.S. holder. The tax basis of a U.S. holder’s shares in a QEF will be increased by amounts that are included in income, and decreased by amounts distributed but not taxed as dividends, under the above rules. In addition, if we are not a PFIC for any taxable year, such U.S. holder will not be subject to the QEF inclusion regime with respect to our public shares for such taxable year.

Alternatively, if we are a PFIC and our public shares constitute “marketable stock,” a U.S. holder may avoid the adverse PFIC tax consequences discussed above if such U.S. holder, at the close of the first taxable year in which it holds (or is deemed to hold) our public shares, makes a mark-to-market election with respect to such shares for such taxable year. Such U.S. holder generally will include for each of its taxable years as ordinary income the excess, if any, of the fair market value of its public shares at the end of such year over its adjusted basis in its public shares. The U.S. holder also will recognize an ordinary loss in respect of the excess, if any, of its adjusted basis of its public shares over the fair market value of its public shares at the end of its taxable year (but only to the extent of the net amount of previously included income as a result of the mark-to-market election). The U.S. holder’s basis in its public shares will be adjusted to reflect any such income or loss amounts, and any further gain recognized on a sale or other taxable disposition of its public shares will be treated as ordinary income.

The mark-to-market election is available only for “marketable stock,” generally, stock that is regularly traded on a national securities exchange that is registered with the Securities and Exchange Commission, including Nasdaq (on which we intend to list the public shares), or on a foreign exchange or market that the IRS determines has rules sufficient to ensure that the market price represents a legitimate and sound fair market value. If made, a mark-to-market election would be effective for the taxable year for which the election was made and for all subsequent taxable years unless the Ordinary Shares ceased to qualify as “marketable stock” for purposes of the PFIC rules or the IRS consented to the revocation of the election. U.S. holders are urged to consult their tax advisors regarding the availability and tax consequences of a mark-to-market election with respect to our public shares under their particular circumstances.

If we are a PFIC and, at any time, have a foreign subsidiary that is classified as a PFIC, U.S. holders generally would be deemed to own a portion of the shares of such lower-tier PFIC, and generally could incur liability for the deferred tax and interest charge described above if we receive a distribution from, or dispose of all or part of our interest in, the lower-tier PFIC or the U.S. holders otherwise were deemed to have disposed of an interest in the lower-tier PFIC. We will endeavor to cause any lower-tier PFIC to provide to a U.S. holder the information that may be required to make or maintain a QEF election with respect to the lower-tier PFIC. There can be no assurance that we will have timely knowledge of the status of any such lower-tier PFIC. In addition, we may not hold a controlling interest in any such lower-tier PFIC and thus there can be no assurance we will be able to cause the lower-tier PFIC to provide such required information.

U.S. holders are urged to consult their tax advisors regarding the tax issues raised by lower-tier PFICs.

A U.S. holder that owns (or is deemed to own) shares in a PFIC during any taxable year of the U.S. holder, may have to file an IRS Form 8621 (whether or not a QEF or mark-to-market election is made) and such other information as may be required by the U.S. Treasury Department. Failure to do so, if required, will extend the statute of limitations until such required information is furnished to the IRS.

The rules dealing with PFICs and with the QEF and mark-to-market elections are very complex and are affected by various factors in addition to those described above. Accordingly, U.S. holders of our public shares are urged to consult their own tax advisors concerning the application of the PFIC rules to our securities under their particular circumstances.

Non-U.S. Holders

This section applies to “Non-U.S. holders.” For purposes of this discussion, a “Non-U.S. holder” means a beneficial owner of public shares that is neither a U.S. holder nor an entity or arrangement treated as a partnership for U.S. federal income tax purposes.

Taxation of Redemption as a Distribution

If the redemption of a Non-U.S. holder’s public shares is treated as a distribution, as discussed above under the section entitled “Tax Treatment of Redeeming Shareholders,” such a distribution generally will constitute a dividend for U.S. federal income tax purposes to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Unless such dividend is effectively connected with the Non-U.S. holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or fixed base maintained by the Non-U.S. holder), such dividend will generally not be subject to U.S. federal income or withholding tax. Distributions in excess of our current and accumulated earnings and profits and that exceed the Non-U.S. holder’s adjusted tax basis in its public shares will similarly not be generally subject to U.S. federal income or withholding tax unless effectively connected with the Non-U.S. holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or fixed base maintained by the Non-U.S. holder).

Dividends paid to a Non-U.S. holder that are effectively connected with the Non-U.S. holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, are attributable to a U.S. permanent establishment or fixed base maintained by the Non-U.S. holder), will be subject to regular U.S. federal income tax as if the Non-U.S. holder were a U.S. resident, subject to an applicable income tax treaty providing otherwise. A Non-U.S. holder that is a corporation for U.S. federal income tax purposes may also be subject to an additional “branch profits tax” imposed at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on its “effectively connected earnings and profits” for the taxable year, as adjusted for certain items.

Taxation of Redemption as a Sale of Public Shares

If the redemption of a Non-U.S. holder’s public shares is treated as a sale, as discussed above under “Tax Treatment of Redeeming Shareholders,” a Non-U.S. holder generally will not be subject to U.S. federal income or withholding tax in respect of gain recognized in connection with such redemption, unless:

●

the gain is effectively connected with the conduct of a trade or business by the Non-U.S. holder within the United States (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment or fixed base maintained by the Non-U.S. holder); or

●

the Non-U.S. holder is an individual who is present in the United States for 183 days or more during the taxable year of the redemption and certain other requirements are met.

Unless an applicable treaty provides otherwise, gain described in the first bullet point above generally will be subject to tax at generally applicable U.S. federal income tax rates as if the Non-U.S. holder were a U.S. resident. A Non-U.S. holder that is a corporation for U.S. federal income tax purposes may also be subject to an additional “branch profits tax” at a 30% rate (or such lower rate specified by an applicable income tax treaty) on its “effectively connected earnings and profits” for the taxable year, as adjusted for certain items.

Gain described in the second bullet point above generally will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which generally may be offset by U.S. source capital losses of the Non-U.S. holder, provided the Non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses.

Information Reporting and Backup Withholding

Generally, information reporting requirements may apply in connection with payments made to U.S. holders or Non-U.S. holders in connection with a redemption of public shares.

Backup withholding of tax (currently at a rate of 24%) generally will apply to cash payments to which a U.S. holder is entitled in connection with a redemption of public shares, unless the U.S. holder provides the applicable withholding agent with a properly completed and executed IRS Form W-9 providing such U.S. holder’s correct taxpayer identification number and certifying that such holder is not subject to backup withholding, or otherwise establishes an exemption. A Non-U.S. holder generally will eliminate the requirement for information reporting and backup withholding by providing certification of its foreign status, under penalties of perjury, on a duly executed applicable IRS Form W-8 or by otherwise establishing an exemption.

Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S. holder or Non-U.S. holder generally will be allowed as a credit against such holder’s U.S. federal income tax liability, if any, and may entitle such holder to a refund, provided that the required information is timely furnished to the IRS.

THE DISCUSSION ABOVE IS BASED ON CURRENT LAW. LEGISLATIVE, ADMINISTRATIVE OR JUDICIAL CHANGES OR INTERPRETATIONS, WHICH CAN APPLY RETROACTIVELY, COULD AFFECT THE ACCURACY OF THE STATEMENTS SET FORTH THEREIN.

IT DOES NOT ADDRESS TAX CONSIDERATIONS THAT MAY VARY WITH, OR ARE CONTINGENT ON, A HOLDER’S INDIVIDUAL CIRCUMSTANCES NOR THE APPLICATION OF ANY U.S. NON-INCOME TAX LAWS OR THE LAWS OF ANY STATE, LOCAL OR NON-U.S. JURISDICTION. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING SUCH MATTERS AND THE TAX CONSEQUENCES OF A REDEMPTION OF THEIR PUBLIC SHARES TO THEM IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES.
