Abstract |
We test the effects of firm`s derivatives hedging and earnings management on foreign exchange rate (FX) exposure using the data of KOSPI firms from 2005 to 2010. This study is distinguished from previous studies in two ways: we measure the expected FX exposure (an ex-ante exposure from firm`s operation activity) and the observed FX exposure (an expost exposure from the stock market) separately, and also consider both derivatives hedging and earnings management to analyze the effectiveness of a firm`s activities for FX exposure management. The main empirical results are as follows: First, derivatives hedging contributes to reducing the firm`s exposure while earnings management does not. Second, if we classify total sample into the positive expected FX exposure sample and the negative expected FX exposure sample, the positive effect of derivatives hedging is found in the firms with positive expected exposure, while earnings management using discretionary accruals is a useful tool to the firms which have negative expected exposure. This implies that managers select the derivatives hedging and the earnings management asymmetrically according to their expected FX exposure. Finally, using many types of derivatives is negatively related with the hedging effects during the period before the 2008 financial crisis. This result suggests that Korean firms used too many kinds of derivatives than they needed in this period. |
