Each such report shall be submitted within 1 month (or such shorter length of time as the Inspector General may specify) after the close of the reporting period involved and shall include with respect to such reporting period—

(1) a summary of any proceedings instituted under section 3005 of this title, and the results of those and of any other such proceedings decided, settled, or otherwise concluded during such period;

(2) the number of cases in which the authority described in section 3005(e) of this title was used;

(6) such other information relating to the investigative activities of the Postal Service as the Inspector General may require.

The information in a report submitted under this section to the Inspector General with respect to a reporting period shall be included as part of the semiannual report prepared by the Inspector General under section 405 of title 5 for the same reporting period. Nothing in this section shall be considered to permit or require that any report by the Postmaster General under this section include any information relating to activities of the Inspector General.
