Quick question

[[wcip]Angel]

A Treasury Bill is a US government security with a maturity of less than one year.

= "If you plan to sell your T-bill, you need to wait at least a year after having purchased it, or there won't be a noticeable profit" ?

As others have mentioned it is sold on a discounted basis from its face value (also known as par value).

They are sold for less than their actual value?

Treasury Bills differ from other US Government debt instruments in that:
1) Their maturity is shorter
2) They don't make coupon payments

= 1) Other forms of lending money to the government for profit takes even longer to yield any profit?
= 2) What is a coupon payment?

As with any bond, note that there is an inverse relationship between price and yield.

Would you mind explaining this?

Thanks!
