17 CFR § 240.12b-23 - Incorporation by reference.
(a) Registration statement or report. Except as provided by this section or in the appropriate form, information may be incorporated by reference in answer, or partial answer, to any item of a registration statement or report.
(b) Financial information. Except as provided in the Commission's rules, financial information required to be given in comparative form for two or more fiscal years or periods must not be incorporated by reference unless the information incorporated by reference includes the entire period for which the comparative data is given. In the financial statements, incorporating by reference, or cross-referencing to, information outside of the financial statements is not permitted unless otherwise specifically permitted or required by the Commission's rules or by U.S. Generally Accepted Accounting Principles or International Financial Reporting Standards as issued by the International Accounting Standards Board, whichever is applicable.
(c) Exhibits. Any document or part thereof filed with the Commission pursuant to any Act administered by the Commission may be incorporated by reference as an exhibit to any statement or report filed with the Commission by the same or any other person. Any document or part thereof filed with an exchange pursuant to the Act may be incorporated by reference as an exhibit to any statement or report filed with the exchange by the same or any other person. If any modification has occurred in the text of any document incorporated by reference since the filing thereof, the registrant must file with the reference a statement containing the text of any such modification and the date thereof.
(d) Hyperlinks. You must include an active hyperlink to information incorporated into a registration statement or report by reference if such information is publicly available on the Commission's Electronic Data Gathering, Analysis and Retrieval System (“EDGAR”) at the time the registration statement or form is filed. For hyperlinking to exhibits, please refer to Item 601 of Regulation S-K (§ 229.601 of this chapter) or the appropriate form.
(e) General. Include an express statement clearly describing the specific location of the information you are incorporating by reference. The statement must identify the document where the information was originally filed or submitted and the location of the information within that document. The statement must be made at the particular place where the information is required, if applicable. Information must not be incorporated by reference in any case where such incorporation would render the disclosure incomplete, unclear, or confusing. For example, unless expressly permitted or required, disclosure must not be incorporated by reference from a second document if that second document incorporates information pertinent to such disclosure by reference to a third document.
