對於解釋企業使用衍生性商品,來決定利率曝險部位的動機假說,可以區分為避險假說與擇時假說,分別以降低現金流量波動及減少資金成本目的。本研究基於考慮高階經理人權力對於公司有其重大影響力以及企業使用利率曝險部位選擇動機之不同,對於企業最終利率曝險部位的影響加以研究。 研究結果顯示,高階經理人權力在不同構面下,對於企業最終利率曝險部位的正反面影響不同,曝險動機也以擇時為主要之考量,顯示企業主要以降低資金成本,支付債權人浮動利息為主,使債權人遭受較大的風險。最後將產業特性及長期負債融資方式的不同對企業曝險部位造成影響,加入討論,結果顯示,不同產業之特性呈顯著影響;而融資方式的不同則呈現不顯著之情形。 CEO power has different positive and negative impact of the interest rate exposure.
