Investopedia explains 'Toggle Note'
Toggle notes provide firms with a way to raise debt while staying afloat during times of strained cash flow. When cash is at a minimum, the firm can use the toggle to defer an interest payment.
While this seems like an attractive option for the firm, it does come at a cost. The increased interest rate provides ample incentive to not miss an interest payment.
