I've decided to call this
type of Series A preferred
stock «upgradeable» (after recently realizing that there are economy class plane
tickets that aren't upgradeable despite having system - wide upgrade certificates).
here is what it says: The following exclusion applies to the Baggage and Personal Effects, Baggage Delay coverages: We will not pay for damage to or loss of: animals; property used in trade, business or for the production of income, household furniture, musical instruments, brittle or fragile articles, or sporting equipment if the loss results from the use thereof; boats, motors, motorcycles, motor vehicles, aircraft, and other conveyances or equipment, or parts for such conveyances; artificial limbs or other prosthetic devices, artificial teeth, dental bridges, dentures, dental braces, retainers or other orthodontic devices, hearing aids, any
type of eyeglasses, sunglasses or contact lenses; documents or
tickets, except for administrative fees required to reissue
tickets; money, stamps,
stocks and bonds, postal or money orders, securities, accounts, bills, deeds, food stamps or credit cards, except as noted above; property shipped as freight or shipped prior to the Scheduled Departure Date; contraband.
