解説

問 23

  • Incorrectア

    This option lists “a, b,” but the tender offer (takeover bid, TOB) in a is an M&A method for acquiring a company, not a measure that strengthens the monitoring and control of management. It is wrong because it includes a, which is not an effective measure.

  • Incorrectイ

    This option lists “a, b, c,” but only b and c are effective for strengthening governance; the tender offer in a is merely a means of acquisition, not a governance-strengthening measure. It is wrong because it includes a.

  • ウ

    正解 The correct answer is “ウ (b, c).” Corporate governance is a mechanism for monitoring and controlling whether managers run the company in line with the interests of stakeholders such as shareholders. The executive officer system in b separates the board of directors, which is responsible for decision-making and oversight, from the executive officers, who are responsible for carrying out operations; this strengthens the board's ability to oversee execution and is therefore effective for strengthening governance. The highly independent outside directors in c can monitor management from an objective standpoint without being bound by internal ties, making this a representative measure for strengthening governance. Therefore the only effective measures are b and c, and “ウ,” which lists exactly these two with nothing missing or extra, is the correct answer.

  • Incorrectエ

    This option lists only “c,” but b—separating management from execution by introducing the executive officer system—also enhances the board's oversight function and is a governance-strengthening measure. It is wrong because it omits the effective measure b and so fails the condition of listing all and only the effective measures.

ここがポイント
  • Corporate governance is a mechanism for monitoring and controlling whether managers run the company in line with the interests of stakeholders such as shareholders; appointing outside directors and separating management from execution (the executive officer system) are measures that strengthen it.
  • Distinguish clearly: a tender offer (takeover bid, TOB) is a method of corporate acquisition (M&A), not a measure for strengthening governance.
