(b)                    						            Contractors shall make	available the foregoing records and supporting evidence for a longer period	of time than is required in 4.703(a)	if-                                                         (1)                          								                A retention	period longer than that cited in 4.703(a) is specified in any	contract clause; or                                                            (2)                          								                The contractor, for its own purposes, retains the foregoing records and supporting evidence for a longer period. Under this circumstance, the retention period shall be the period of the contractor’s retention or 3 years after final payment, whichever period expires first.                                                            (3)                          								                The contractor does not meet the original due date for submission of final indirect cost rate proposals specified in paragraph (d)(2) of the clause at 52.216-7, Allowable Cost and Payment. Under these circumstances, the retention periods in 4.705 shall be automatically extended one day for each day the proposal is not submitted after the original due date.                                                                             (c)                    						            Nothing in this section shall be construed to preclude a contractor from duplicating or storing original records in electronic form unless they contain significant information not shown on the record copy. Original records need not be maintained or produced in an audit if the contractor or subcontractor provides photographic or electronic images of the original records and meets the following requirements:                                                         (1)                          								                The contractor or subcontractor has established procedures to ensure that the imaging process preserves accurate images of the original records, including signatures and other written or graphic images, and that the imaging process is reliable and secure so as to maintain the integrity of the records.                                                            (2)                          								                The contractor or subcontractor maintains an effective indexing system to permit timely and convenient access to the imaged records.                                                            (3)                          								                The contractor or subcontractor retains the original records for a minimum of one year after imaging to permit periodic validation of the imaging systems.                                                                             (d)                    						            If the information described in paragraph (a) of this section is maintained on a computer, contractors shall retain the computer data on a reliable medium for the time periods prescribed. Contractors may transfer computer data in machine readable form from one reliable computer medium to another. Contractors’ computer data retention and transfer procedures shall maintain the integrity, reliability, and security of the original computer data. Contractors shall also retain an audit trail describing the data transfer. For the record retention time periods prescribed, contractors shall not destroy, discard, delete, or write over such computer data.4.704 Calculation of retention periods.       (a)                    						            The retention periods in 4.705 are calculated from the end of the contractor’s fiscal year in which an entry is made charging or allocating a cost to a Government contract or subcontract. If a specific record contains a series of entries, the retention period is calculated from the end of the contractor’s fiscal year in which the final entry is made. The contractor should cut off the records in annual blocks and retain them for block disposal under the prescribed retention periods.                                          (b)                    						            When records generated during a prior contract are relied upon by a contractor for certified cost or pricing data in negotiating a succeeding contract, the prescribed periods shall run from the date of the succeeding contract.                                          (c)                    						            If two or more of the record categories described in 4.705 are interfiled and screening for disposal is not practical, the contractor shall retain the entire record series for the longest period prescribed for any category of records.4.705 Specific retention periods.       The contractor shall retain the records identified in 4.705-1 through 4.705-3 for the periods designated, provided retention is required under 4.702. Records are identified in this subpart in terms of their purpose or use and not by specific name or form number. Although the descriptive identifications may not conform to normal contractor usage or filing practices, these identifications apply to all contractor records that come within the description.    4.705-1 Financial and cost accounting records.
