Sec. 41.31  Records to be maintained and reports to be filed.

    Common carriers subject to the Act shall maintain records and file 
reports as follows:
    (a) Each such carrier shall maintain its records in such manner as 
to reflect at all times the name and address of every person holding a 
telegraph or telephone frank and the office, employment or relationship 
held by each such person entitling him to a frank; and each such carrier 
shall keep such basic records as would enable it, if ordered by the 
Commission, to compile a statement for the last preceding calendar year 
prior to such order or for any other period during which it is required 
by other rules to retain such records, showing the above information 
together with the number of franked communications handled under each 
frank during such period and the aggregate charges in dollars which 
would have accrued to the carrier for all of the free service rendered 
under each frank during such period if charges for all such 
communications had been collected at the published tariff rates.
    (b) With respect to the communications referred to in Sec. 41.13 
every carrier subject to the Act shall maintain its records in such a 
manner as to show the number of each class of such communications 
handled free of charge: Provided, That with respect to personal 
telephone calls of officers, agents, or employees of common carriers 
subject to the Act made free of charge or at reduced rates from 
telephone company official stations it shall be sufficient, in lieu of 
such record maintenance, if the carrier be at all times prepared, upon 
appropriate request, to make studies which will show the number of each 
class of such communications handled free of charge or at reduced rates.
    (c) Each such carrier shall maintain its records in such a manner as 
to show the number of reports of positions of ships at sea furnished to 
newspapers of general circulation without charge, or at nominal charges, 
as authorized in section 201(b) of the Act.
