Explanation:

Annuity is a term that describes streams of payments made at equal intervals. Examples of such payments (annuities) are monthly home mortgage payments, monthly insurance payment, regular deposits into a savings account, monthly pension payments and life annuity (payment to an individual for the rest of his/her lifetime).  

The equal intervals which annuities payments are made could be yearly, quarterly, weekly, monthly or any other equal interval of time.

a naked warrant, also known as a covered warrant, is a derivative that allows the holder to buy or sell a security, such as a bond or share. unlike a normal warrant, it is not attached to a newly issued bond or preferred stock.

unsecured bonds: they are not secured by a specific asset, but rather by "the full faith and credit" of the issuer. in other words, the investor has the issuer's promise to repay but has no claim on specific collateral. debt, such as unsecured bond debt, is said to be “subordinated,” or junior, to secured debt.
