30 January 2012


IDA's Directed Amendments to SingTel's Further Revised RIO

IDA has completed its review of SingTel's Further Proposed Modifications to Schedules 8A, 8D and 9. While IDA found the majority of the proposed modifications to these Schedules to be in conformity with the requirements expressed in IDA's 27 October 2011 Direction, IDA also concluded that some failed to give full effect to the required modifications.

On 30 January 2012, IDA directed SingTel to incorporate specific drafting language ("Directed Amendments") to Schedules 8A, 8D and 9 of SingTel's Further Revised RIO. SingTel's Further Proposed Revised RIO incorporating the Directed Amendments is hereby approved and will take effect from the said date.

IDA's Directed Amendments to SingTel's Further Revised RIO

In IDA's review of SingTel's Further Proposed Modifications, IDA found the majority of SingTel's Further Proposed Modifications to be in conformity with IDA's requirements as expressed in IDA's 27 October 2011 Direction, save for: (a) SingTel's Further Proposed Modifications to Schedules 8A, 8D and 9, which are pending the submission of further information/clarification from SingTel; and (b) certain of SingTel's other Further Proposed Modifications, which IDA concluded fail to give full effect to IDA's required modifications.

On 3 January 2012, IDA directed SingTel to incorporate specific drafting language ("Directed Amendments") to its Further Revised RIO. In light of the ongoing review of Schedules 8A, 8D and 9 of SingTel's RIO, IDA will specify the effective date of SingTel's revised RIO at a later time, following the completion of such review and the issuance of IDA's approval and/or directed amendments in respect of these Schedules.

With significant developments of the telecom landscape in Singapore since the last review of SingTel's RIO in 2005, IDA has identified several key issues that may have significant implications on the relevance and scope of SingTel's RIO going forward. IDA would like to hear the industry's views and comments on these issues before requiring SingTel to submit a proposed revised RIO. For the avoidance of doubt, pursuant to Sub-section 6.3.6 of Telecom Competition Code 2010, IDA will conduct a subsequent public consultation on SingTel's proposed revised RIO.
