Junior Security A security that ranks lower than other securities in regards to the owner's claims on assets and income in the event of the issuer becoming insolvent. Investopedia Says: When bankruptcy occurs, holders of both preferred shares and debt securities have first claim on the remaining assets. Only after preferred shareholders have been paid back, remaining assets (if any) are divided among common shareholders.
