Description of timing |  |  | The Company’s contracts with customers typically provide for an initial term of one year, with renewable one year service terms, cancellable by either party upon 30 to 90 days’ notice after an initial period of 60 to 120 days.At September 30, 2020, the Company had $521.4 million related to performance obligations that were unsatisfied or partially unsatisfied for which the Company expects to recognize revenue. The Company expects to recognize revenue on approximately 29.3% of the remaining performance obligations over the next 12 months, with the balance to be recognized thereafter. These amounts exclude variable consideration primarily related to performance obligations that consists of a series of distinct service periods with revenues based on future performance that cannot be estimated at contract inception. The Company also has elected to apply the practical expedient that permits exclusion of information about the remaining performance obligations with original expected durations of one year or less. |  |
