The order passed by the Office of the Principal Accountant General (Civil Audit), Tamil Nadu & Pondicherry reads as under: "E II/Pen/05-06/101 Dated 14.9.2005 To Sri.M.A.Manickam Retd. Addl. Chief Accounts Officer, Chennai Port Trust, Chennai 600 001. Sir, Sub: Pension-Reckoning of Addl. Charge allowance for calculation of average Emoluments for pension - reg.----- The pay actually drawn by a Govt. Servant for the post held by him substantively or in an officiating capacity immediately before his retirement is treated as Emoluments for the purpose of calculation of pensionary benefits as per Rule 33 of CCS Pension Rules read with FR 9(21) of FRSR General Rules. So (1) if a Govt. Servant is formally appointed to hold full charge of the duties of a higher post in the same office and in the same line of promotion in addition to his ordinary duties and (2) is allowed the pay admissible to him if he is appointed to officiate in the higher post, the pay actually drawn by him can be taken for calculation of pensionary benefits. But if the Govt. servant is being paid a charge allowance as one lumpsum (separate element) for holding charge of the duties of a higher post in addition to his ordinary duties, the allowance so paid cannot be considered as part of pay for calculation of pensionary benefits. This is for your information." 7.
