Authorised capital increase not triggered by reclassification of unissued shares; no additional registration fees but Forms 5 and 6 required. Where cancellation of a class of unissued shares and simultaneous creation of unclassified shares of the same denomination does not raise the company's total authorised capital beyond the original authorised amount on which fees were paid, no further registration fees are payable; the company must still file Form Nos. 5 and 6 to complete the Registrar's records.
