NESTLE SEEKING AUTHORISATION FOR CERTIFICATE ISSUE Nestle SA <NESZ.Z> said it would seek shareholder approval to issue participation certificates up to 20 pct of share capital, instead of the current limit of 10 pct. It said it wanted this authorisation in view of future certificate issues. Nestle's nominal capital amounts to 330 mln Swiss francs. Nestle reported net profits of 1.79 billion francs for 1986, up 2.2 pct from 1985, while turnover fell 9.9 pct to 38.05 billion as the Swiss franc strengthened against other currencies. The parent company's net profit rose to 666.6 mln francs from 592.9 mln in 1985, and the company planned an unchanged dividend of 145 francs per share and 29 francs per certificate after placing 170 mln francs in reserves, against 95 mln last year. The payout represented 27.6 pct of group net profit, against 28.2 pct last year. Nestle said it had also invited Fritz Leutwiler, former president of the Swiss National Bank and currently chairman of BBC AG Brown Boveri und Cie <BBCZ.Z>, to join the Nestle board.
