Per the Thousands Block Pooling Administration Guidelines (TBPAG):

Available Numbers is defined as “Available numbers are numbers that are available for assignment to subscriber access lines, or their equivalents, within a rate center and are not classified as assigned, intermediate, administrative, aging, or reserved. Available numbers is a residual category that can be calculated by subtracting a sum of numbers in the assigned, reserved, intermediate, aged, and administrative primary categories from the total of numbers in the inventory of a code or block holder (FCC 00-104 §52.15 (f)(1) (iv)).” . Assigned Numbers is defined as “Assigned numbers are numbers working in the PSTN under an agreement such as a contract or tariff at the request of specific end users or customers for their use, or numbers not yet working but having a customer service order pending. Numbers that are not yet working and have a service order pending for more than five calendar days shall not be classified as assigned numbers. (FCC 00-104 §52.15 (f)(1) (iii)) Ported-out numbers should be included as a subcategory of assigned numbers. (FCC 00-104 ¶ 36).”

PAS validates that the numbers provided in section A. (Available Numbers) and section B. (Assigned Numbers) may not exceed the total numbers provided in section C. (Total Numbering Resources). PAS does not require that A. + B. must equal C.
