An 
option contract that a 
publicly-traded company issues to a 
shareholder giving the shareholder the right but not the obligation to 
sell his/her 
shares back to the company at a certain 
strike price on or before the contract's 
expiration date. A transferable put right protects the shareholder from the possibility that the share price will drop precipitously, resulting in a massive loss. However, the right increases the company's 
risk that it may have to honor the 
exercise of a number of options at a high price, resulting in financial difficulty.
