The Securities and Exchange Commission ("Commission") is amending Rule 19b-4(a) under the Securities Exchange Act of 1934 (the "Exchange Act") so that references to "business day" in Section 19(b) of the Exchange Act and Rule 19b-4 thereunder refer to a day other than a Saturday, Sunday, Federal holiday, a day that the U.S. Office of Personnel Management ("OPM") has announced that Federal agencies in the Washington, DC area are closed to the public, a day on which the Commission is subject to a Federal government shutdown in the event of a lapse in appropriations, or a day on which the Commission's Washington, DC office is otherwise not open for regular business.
