text: Historically, Sprint determined monthly service charges at the beginning of each calendar year. Sprint calculated the 
  costs to provide these services for its network partners and required a final settlement against the charges actually paid. 
  If the costs to provide these services were less than the amounts paid by the Sprint’s network partners, Sprint issued a 
  credit for these amounts. If the costs to provide the services were more that the amounts paid by Sprint’s network 
  partners, Sprint charged the network partners for these amounts. For the years presented, the Company recorded the 
  actual costs, after the adjustments, which were recorded for these services provided by Sprint.
