Notes to the consolidated financial statements
1. Segmental analysis
The following segmental analysis is presented in accordance with management responsibilities and economic characteristics, including consideration of the risks and returns, of our business activities. The Company assesses the performance of its businesses principally on the basis of operating profit before exceptional items, remeasurements and stranded cost recoveries. The primary reporting format is by business and the secondary reporting format is by geographical area. The following table describes the main activities for each business segment:
| Transmission UK | High voltage electricity transmission networks, the gas transmission network in the UK, the UK liquefied natural gas (LNG) storage activities and the French electricity interconnector. |
| Transmission US | High voltage electricity transmission networks in New York and New England. |
| Gas Distribution UK | Four of the eight regional networks of Great Britain’s gas distribution system. |
| Gas Distribution US | Gas distribution in New York and New England. |
| Electricity Distribution & Generation US | Electricity distribution in New York and New England, and electricity generation in New York. |
Other activities primarily relate to non-regulated businesses and other commercial operations not included within the above segments, including UK-based gas metering activities; UK property management; a UK LNG import terminal; other LNG operations; US unregulated transmission pipelines; US home energy services; US gas fields; together with corporate activities, including business development.
Discontinued operations comprise the Ravenswood generation station in New York City and the engineering and communications operations in the US acquired as part of the KeySpan acquisition. The Ravenswood generation station was sold on 26 August 2008, KeySpan Communications was sold on 25 July 2008 and one of our KeySpan engineering companies was sold on 11 July 2008. Subsequent to the year end, two further engineering companies were sold. For the year ended 31 March 2008, discontinued operations also include the wireless infrastructure and communications operations in the UK and the US and an electricity interconnector in Australia. The wireless infrastructure operations in the UK were sold on 3 April 2007; the US wireless operations were sold on 15 August 2007; and the Basslink electricity interconnector in Australia was sold on 31 August 2007. The results for discontinued operations are disclosed in note 8.
Sales between businesses are priced having regard to the regulatory and legal requirements to which the businesses are subject.

The table above represents revenue from continuing operations only, as disclosed in the consolidated income statement. For additional disclosures relating to discontinued operations, refer to note 8.
The analysis of revenue by geographical area is on the basis of destination. There are no material sales between the UK and US geographical areas.
Approximately 6% (2008: 9%; 2007: 9%) of revenue for the year ended 31 March 2009 amounting to approximately £1.0bn (2008: £1.0bn; 2007: £0.8bn) derives from a single customer, the Centrica group. The majority of this revenue is in the Gas Distribution UK segment with lesser amounts in the Transmission UK segment and in other activities.
In accordance with the Company’s accounting policy on revenue recognition, where revenue received or receivable exceeds the maximum amount permitted by regulatory agreement and adjustments will be made to reflect the over-recovery, no liability is recognised. Similarly, no asset is recognised where a regulatory agreement permits adjustments to be made to future prices in respect of an under-recovery. In the UK, there was an under-recovery of £52m at 31 March 2009 (2008: £23m; 2007: £33m). In the US, under-recoveries and other regulatory entitlements to future revenue (including stranded cost recoveries) amounted to £2,289m at 31 March 2009 (2008: £1,652m 2007: £1,930m).
