Enclosures:  1.  BT Pension Scheme announcement made on 18 December 2006







DC06-675                                                       December 18, 2006

BT AND TRUSTEES ANNOUNCE AGREEMENT ON TRIENNIAL FUNDING VALUATION OF THE BT
PENSION SCHEME

BT and the Trustees of the BT Pension  Scheme (BTPS) today  announced  that they
had reached  agreement on the triennial  funding  valuation of the BTPS. Under a
new and more  conservative  actuarial  methodology,  consistent  with regulatory
guidance,  the deficit as at December 31 2005 has been  calculated  as GBP3.4bn.
Had the previous valuation approach been used on this occasion, the Scheme would
be in surplus. BT will make deficit payments equivalent to GBP280m per annum for
10 years with the first three years instalments paid up front.
Key features of the agreement are:

   -An advanced payment of GBP840m, representing three years' instalments of
    GBP280m, into the scheme by 30th April 2007 - GBP500m of which is to be paid
    in December 2006.
   -Payments of GBP280m pa in 2009-2015 inclusive.
   -A "true-up/true down" agreement has been reached to adjust post 2008
    Company contributions depending on investment performance. This for example
    gives the Trustees insurance should investment performance not be in line
    with expected returns. Subject to Trustee agreement, it gives the company a
    benefit where investment returns exceed 3.2% real.
   -Employee contributions will remain at 6%. Joint employer/employee
    contribution will increase from 18.2% to 19.5% from 1 January 2007.

Sir Christopher Bland, BT Chairman said "This is a fair and prudent deal for
pensioners and for shareholders, which re-confirms that BT stands fully behind
its pension obligations. The Scheme is well-managed and assets have grown very
strongly in recent years".

Sir Tim Chessells, Chairman of BTPS Trustees said: "This agreement offers
balance and certainty. It secures additional strong support to the benefit of
pensioners, is consistent with the interests of scheme members and is further
underpinned by having a financially strong sponsor".

Hanif Lalani, BT's Group Finance Director said: "Considerable extra prudence has
been built into the deficit calculation since 2002. We are wholly comfortable
with this agreement, and there is no impact on our profit and loss account."

Notes to editors:

 1. The BT Pension Scheme (BTPS) is a defined benefit (DB) scheme and was closed
    to new members on 1 April 2001. A defined contribution (DC) scheme, the BT
    Retirement Plan, is in place for those joining since 1 April 2001.
 2. Funding valuation: The previous full triennial valuation - as at 31 December
    2002 - concluded that there was a funding deficit, which BT agreed to repay
    at GBP232m per annum over fifteen years. These sums were additional to
    regular employer contributions.
 3. The BTPS had assets at 31 December 2002 of GBP23bn, rising to over GBP34bn
    at 31 December 2005 and to GBP36bn by 30 September 2006.
 4. Scheme assets represent 91% of liabilities at 31 December 2005. These
    liabilities have been expressed at present value using more prudent discount
    rates than in 2002. The new discount rates average 2.5% per annum real over
    the next three years as opposed to 4.5% per annum real in 2002.
 5. Accounting valuation: BT's IAS19 accounting deficit in relation to the BTPS
    at 31 December 2005 was GBP4.0bn (GBP2.8bn net of tax), and GBP2.8bn (GBP2bn
    net of tax) as at 30 September 2006.
 6. There is no impact from this agreement on the company's profit and loss
    account.
 7. The "true up/true down" agreement between the company and trustees means
    that if the actual investment return from scheme assets over the period
    between triennial valuations is below 3.2% real per annum, BT will make
    further cash contributions to BTPS. If investment returns exceed 3.2%, BT's
    future deficit contributions will be reduced provided Trustees agree. In
    doing so, Trustees must of course act in accordance with relevant regulatory
    guidance, notably that any shortfall should be eliminated as quickly as the
    employer can reasonably afford after assessing the employers' covenant. The
    adjustments take effect post 2008 and are capped each way at GBP280m p.a.
 8. The existence of the Crown Guarantee, given to BT on privatisation in
    relation to pensions liabilities for those joining BTPS before 6 August
    1984, has not been taken into account in determining the valuation results.
 9. Liabilities assumptions have been updated since 2002. These include the
    following mortality assumption:

      + -average life expectancy after retirement at 60 years:

                                        Males 23.8 years

                                        Females 25.4 years

- future improvement every 10 years of about 1 year
