(2) After abatement of a jeopardy assessment in whole or in part, a deficiency may be assessed and collected in the manner authorized by law as if the jeopardy assessment or part thereof so abated had not existed. If a notice of deficiency has been sent to the taxpayer before the abatement of the jeopardy assessment in whole or in part, whether such notice was sent before or after the making of the assessment, such abatement will not affect the validity of the notice or of any proceedings for redetermination based thereon. The period of limitation on the making of assessments and the beginning of levy or a proceeding in court for collection in respect of any deficiency shall be determined as if the jeopardy assessment so abated had not been made, except that the running of such period shall in any event be suspended for the period from the date of such jeopardy assessment until the expiration of the tenth day after the date on which such jeopardy assessment is abated in whole or in part. The provisions of this subparagraph may be illustrated by the following example: Example. On March 18, 1958, 28 days before the last day of the 3-year period of limitations on assessment, a jeopardy assessment is made in respect of a proposed deficiency. On May 2, 1958, before the mailing of the notice of deficiency provided by section 6861(b), this assessment is abated. By virtue of this subparagraph, the last day of the period of limitations for the making of an assessment is June 9, 1958, that is, the 38th day after the date of the abatement. If the notice of deficiency provided for in section 6861(b) has been sent before the abatement, the running of the period of limitations on assessment would have been suspended pursuant to the provisions of the section 6503(a).
