Adjustment of pro forma figures in TeliaSonera's Year-End Report January-December 2002

Adjustment of pro forma figures in TeliaSonera's Year-End Report January-
December 2002

In TeliaSonera's Year-End Report 2002, published on February 19, 2003,
calculation errors regarding the pro forma figures for 2002 have been
noted. The corrections concern eliminations of Com hem and Telia
Finland, among others, in the column "Adjustments". Corrections have
also been made regarding pro forma taxes.

Neither the legal results nor Telia's stand-alone or Sonera's stand-
alone results are affected.

TeliaSonera's outlooks, stated in the report, are not affected by the
corrected pro forma figures.

The correct pro forma figures are shown below in tables corresponding to
the year-end report.

As stated in the year-end report, TeliaSonera is in the process of
acquiring the remaining outstanding shares and warrants in Sonera; thus,
the final amounts of fair value adjustments and goodwill are subject to
refinement. This may later on lead to further adjustments of the pro
forma figures.

Financial Information/Underlying EBITDA
This year-end report includes information on "underlying EBITDA" and on
other similar "underlying" measures of TeliaSonera's results of
operations. Underlying EBITDA equals operating income before
depreciation, amortization and write-downs, net of items not reflecting
underlying business operations and excluding income from associated
companies. Items not reflecting underlying business operations include
capital gains and losses, restructuring/phase-out of operations,
personnel redundancy costs, and expenses in conjunction with the initial
public offering in 2000. TeliaSonera's management uses underlying EBITDA
and operating income as the principal measures for monitoring
profitability in internal operations. Management believes that, besides
operating income, underlying EBITDA is also a measure commonly reported
and widely used by analysts, investors and other interested parties in
the telecommunications industry. Accordingly, underlying EBITDA is
presented to enhance the understanding of TeliaSonera's historical
operating performance.
Underlying EBITDA, however, should not be considered as an alternative
to operating income as an indicator of our operating performance.
Similarly, underlying EBITDA should not be considered as an alternative
to cash flows from operating activities as a measure of liquidity.
Underlying EBITDA is not a measure of financial performance under IAS or
U.S. GAAP and may not be comparable to other similarly titled measures
for other companies. Underlying EBITDA is not meant to be predictive of
potential future results.
