We investigate how dened benet pension schemes of FTSE rms are valued by the equity market, focusing on how future liabilities are discounted (since UK data allows us to estimate the duration of pension liabilities fairly accurately). We nd that equity market valuation is consistent with discounting without allowing for credit risk. This diers from the approach used in published accounts for which IAS 19 (and SFAS No. 158, its US equivalent) allows for discounting with a corporate bond yield. The dierence is signicant, as credit risk free discounting would decrease the reported value of FTSE 100 rms by about 7%.
