The India side was ruled to be an over short of its target when time allowances were taken into consideration. Match referee Chris Broad imposed a 20% fine on Dhoni while each of his player received 10%-fines.
"The offence is contrary to Article 2.5.1 of the code which relates to minor over-rate offences. The finding and penalty were imposed following a full disciplinary hearing," the statement said.
India won the first match by 21 runs on Saturday night.
