我國上市櫃公司應自2013年起採用國際會計準則編製財務報表，而非上市上櫃及興櫃之公開發行公司、信用合作社及信用卡公司則自2015年起適用，故實行國際會計準則已是各企業極力推動之專案計畫。本文運用個案研究方法，討論國際會計準則對通訊設備業之衝擊，並藉由個案公司導入國際會計準則之過程，了解如何規劃導入，如何進行影響性評估，及個案公司採用國際會計準則與現行之中華民國一般公認會計原則之差異項目，並針對其影響最大之IAS 18收入及IAS 21匯率變動做深入探討。對於個案公司採用國際會計準則後，依IAS 18「收入」，分析個案公司收入認列時點、銷貨交易辨認之會計處理、遞延收入會計處理、遞延收入資訊系統紀錄及收入於財稅差異解決方法，並依IAS 21「匯率變動之影響」規定，分析通訊設備業導入功能性貨幣之步驟及如何評估功能性貨幣主要指標和次要指標。
