The registration fee is calculated in accordance with Rule 457(o) under the Securities Act, based on an estimate of the proposed maximum aggregate offering price.

Includes the offering price of additional Ordinary Shares that the underwriters have the option to purchase to cover over-allotments, if any.</ffd:OfferingNote>
    <ffd:OfferingNote contextRef="offrl_2" id="ixv-457">In accordance with Rule 457(g) under the Securities Act, because the Ordinary Shares of the registrant underlying Representative's Warrants are registered hereby, no separate registration fee is required with respect to Representative's Warrants registered hereby.</ffd:OfferingNote>
    <ffd:OfferingNote contextRef="offrl_3" id="ixv-458">Representative's Warrants are exercisable at a per share exercise price equal to 125% of the public offering price. As estimated solely for the purpose of calculating the registration fee pursuant to Rule 457(g) under the Securities Act, the proposed maximum aggregate offering price of the Representative's Warrants is equal to 125% of $989,000 (which is equal to 5% of 19,780,000).</ffd:OfferingNote>
