Smith & Nephew realises investment in BSN medical

16 December 2005

Smith & Nephew plc (LSE: SN, NYSE: SNN) announced earlier today the signing,
together with Beiersdorf AG its joint venture partner, of an agreement to sell
BSN medical ("BSN") for an enterprise value of EUR1030 million to Montagu
Private Equity.  Completion of the transaction is conditional upon competition
clearances being received and is expected to take place in the first quarter of

Smith & Nephew expects its share of the proceeds to be around EUR495 million
(GBP330 million) in cash, after adjusting for net debt of BSN and certain other
items, and will be applied in repaying group borrowings.  Net assets subject to
disposal are GBP145 million and the gain on disposal will be around GBP170
million, after transaction costs of around GBP15 million, and will be accounted
for on completion.  Cash tax of around GBP20 million will be payable on the

Commenting on the sale, Sir Christopher O'Donnell, Chief Executive of Smith &
Nephew, said:

"We established BSN with Beiersdorf in 2001 as a planned exit from our lower
growth hospital supply businesses.  Over the last five years through business
rationalisation it has established itself as a highly profitable business and a
market leader in many of its markets.  We are very pleased to have achieved this
sale at a value which represents nearly twice the revenues of the business for
the current year."

Commenting on the effect of the sale on Smith & Nephew, Peter Hooley, Finance
Director, said:

"The sale of BSN enhances the growth prospects and the financial strength of
Smith & Nephew to continue to invest in expanding its businesses.  The profits
of BSN, which are accounted for on an equity basis, are expected to contribute
approximately GBP161/2m after tax to group earnings in 2005.  Whilst  the sale
of BSN is expected to dilute Smith & Nephew's growth in adjusted earnings per
share by just under 4%, in 2006, it is expected in subsequent years to augment
that growth by approaching 1% per annum."
