c MOD can terminate the contract, or require the replacement of individual service providers, for continued poor performance. Persistent poor performance is subject to a ratchet mechanism, and if poor performance reaches a certain level within any six-month, one-year or three-year period, MOD can terminate the contract. In addition, MOD can require the replacement of individual service providers for consistent poor performance. Figure 5 shows the level of poor performance that can lead to the replacement of service providers and termination of the contract.
