Pension math
Mary Walsh of the NYT reports on new accoutning rules for financial statement disclosure of pension and benefit funds in the US. These rules require more accurate recognition of future costs of pension, health and welfare plans. This serves to increase liabilities on the balance sheet, which makes a company look less valuable (well, which accurately represents how much less valuable the company is than it previously looked).
It is important for accurate valuation, but you can be sure that this will put more pressure on companues to reneg on their pension promises. As stated before in this space, the typical reaction is to cut pension and benefit plans, which is the equivalent of a massive reduction in wages. Link.
