De-SPAC Consummation Timeframe, Plans if it Fails [Text Block]

If we do not complete our initial business combination within the completion window, while we do not currently intend to seek shareholder approval to amend our amended and restated memorandum and articles of association to extend the amount of time we will have to consummate an initial business combination, we may elect to do so in the future.

De-SPAC Consummation Timeframe, Extension Failure, Consequences to Sponsor [Text Block]

There is no limit on the number of extensions that we may seek; however, we do not expect to extend the time period to consummate our initial business combination beyond 36 months from the closing of this offering. If we determine not to or are unable to extend the time period to consummate our initial business combination or fail to obtain shareholder approval to extend the completion window, our sponsor’s investment in our founder shares and our private placement units will be worthless.

SPAC Additional Financing Plans, Impact on Security Holders [Text Block]

Potential Additional Financings

We may need to obtain additional financing to complete our initial business combination, either because the transaction requires more cash than is available from the proceeds held in our trust account or because we become obligated to redeem a significant number of our public shares upon completion of the business combination, in which case we may issue additional securities or incur debt in connection with such business combination. If we raise additional funds through equity or convertible debt issuances, our public shareholders may suffer significant dilution and these securities could have rights that rank senior to our public shares. If we raise additional funds through the incurrence of indebtedness, such indebtedness would have rights that are senior to our equity securities and could contain covenants that restrict our operations. Further, as described above, due to the anti-dilution rights of our founder shares, our public shareholders may incur material dilution. In addition, we intend to target businesses with enterprise values that are greater than we could acquire with the net proceeds of this offering and the sale of the private placement units, and, as a result, if the cash portion of the purchase price exceeds the amount available from the trust account, net of amounts needed to satisfy any redemptions by public shareholders, we may be required to seek additional financing to complete such proposed initial business combination. We may also obtain financing prior to the closing of our initial business combination to fund our working capital needs and transaction costs in connection with our search for and completion of our initial business combination. There is no limitation on our ability to raise funds through the issuance of equity or equity-linked securities or through loans, advances or other indebtedness in connection with our initial business combination, including pursuant to forward purchase agreements or backstop agreements we may enter into following consummation of this offering. Subject to compliance with applicable securities laws, we would only complete such financing simultaneously with the completion of our initial business combination. If we are unable to complete our initial business combination because we do not have sufficient funds available to us, we will be forced to liquidate the trust account. In addition, following our initial business combination, if cash on hand is insufficient, we may need to obtain additional financing in order to meet our obligations. There are no prohibitions on our ability to issue securities or incur debt in connection with our initial business combination. We are not currently a party to any arrangement or understanding with any third party with respect to raising any additional funds through the sale of securities, the incurrence of debt or otherwise.

SPAC, Trust or Escrow Account, Material Terms [Text Block]

NYSE rules provide that at least 90% of the gross proceeds from our initial public offering and the sale of the private placement units must be deposited in a trust account. Of the net proceeds of this offering and the sale of the private placement units, $260,000,000 (or $299,000,000 if the underwriters’ overallotment option is exercised in full), including $3,000,000 (this amount may be reduced to $850,000 in certain circumstances, as further described in “Underwriting”) to pay the deferred underwriting commissions, will be placed into a U.S. based trust account with Continental Stock Transfer & Trust Company acting as trustee, and $1,500,000 will be used to pay expenses in connection with the closing of this offering and for working capital following this offering. The proceeds held in the trust account will initially be invested only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations; the holding of these assets in this form is intended to be temporary and for the sole purpose of facilitating the intended business combination. To mitigate the risk that we might be deemed to be an investment company for purposes of the Investment Company Act, which risk increases the longer that we hold investments in the trust account, we may, at any time (based on our management team’s ongoing assessment of all factors related to our potential status under the Investment Company Act), instruct the trustee to liquidate the investments held in the trust account and instead to hold the funds in the trust account in cash or in an interest bearing demand deposit account at a bank. Additionally, when we determine to hold the funds in the trust account as cash or in demand deposit accounts at a bank, the amount of interest we may receive would likely be less. Except with respect to interest earned on the funds held in the trust account that may be released to us as permitted withdrawals, the proceeds from this offering and the sale of the private placement units will not be released from the trust account until the earliest to occur of (i) the completion of our initial business combination (including the release of funds to pay any amounts due to any public shareholders who properly exercise their redemption rights in connection therewith), (ii) the redemption of any public shares properly submitted in connection with a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association (A) in a manner that would affect the substance or timing of our obligation to redeem 100% of our public shares if we do not complete an initial business combination within the completion window or (B) with respect to any other provision relating to the rights of holders of our Class A ordinary shares or pre-initial business combination activity or (iii) the redemption of our public shares if we are unable to complete our business combination within the completion window, and do not hold a shareholder vote to amend our amended and restated memorandum and articles of association to extend the amount of time we will have to consummate an initial business combination, subject to applicable law. Based on current interest rates and the taxes we currently expect to be applicable to us, we expect that the interest earned on the trust account will be sufficient to pay our taxes and to fund permitted withdrawals.
