Cryopreserved patients must be cared for for at least decades and some anticipate centuries. During this time, some caretaker organization must look after the patients. This involves paying the rent and utilities, replacing liquid nitrogen, maintaining and replacing dewars, hiring and paying staff, and a host of other activities that must be done reliably and economically. The usual arrangement is for the patient to make a lump sum payment into a common fund, the interest from which will then pay the expenses of maintaining a group of patients in cryopreservation for whatever period of time might be required. At Alcor, the lump sum payment is made into the PCT (Patient Care Trust), and the payment made by each patient is the “PCT allocation,” taken from the total payment made by the patient at the time of cryopreservation. Determining the appropriate amount of the PCT allocation can raise questions whose answers are not always obvious and can sometimes be quite dilemmatic.

When different kinds of patients occupy different volumes in the long term care system, making the PCT allocation proportional to the volume occupied by the patient provides a robust and stable answer to this question under a wide range of conditions.
