Note 2 – Unbilled Services
 
The Company’s unbilled services consist primarily of unbilled labor and production overhead, as well as production supplies. Production supplies are stated at the lower of cost or market.

The Company’s unbilled services are primarily valued on the first-in, first-out (FIFO) basis, with the exception of two of the Company’s locations which are valued using the last-in, first-out (LIFO) method. The Company periodically evaluates the realizability of unbilled services and adjusts the carrying value as necessary.
