We analyze the effects of fair value reporting standards (FVR) SFAS 133 and IAS 39. We study the effects of FVR on corporate foreign exchange (FX) exposures. We observe reductions in FX exposures to developed market currencies post-FVR. Risk reductions mainly affect U.S. MNCs not control groups of DCs. We report changes in FX exposure asymmetry affecting MNCs and DCs.
