A registration of securities to be offered in series or a registration for delayed or continuous offering and sale of securities for which a single registration statement has been filed under the Securities Act of 1933 may be filed by coordination. The initial filing shall be made in accordance with section 36b-17 of the general statutes. Prior to the offering of each subsequent series or each particular offering of securities for which a registration for delayed or continuous offering and sale has been filed, the registrant shall submit for each such series or offering a Form U-1, the filing fee required by section 36b-19(b) of the general statutes and any additional information given or any documents filed with the United States Securities and Exchange Commission. The registration of each subsequent series or particular offering so filed shall be effective automatically once the commissioner receives (a) written notice of Securities and Exchange Commission effectiveness of each amendment to the issuer's federal registration statement relating to that series or offering and the final pricing information, if any, or (b) pricing telegrams with respect to series or offerings for which no such amendment has been filed.
