Future Outlook and Monitoring Factors
The stable outlook reflects Acuite's expectation of consistent performance from the trust's diversified asset base. Key monitoring factors include sustained toll collections, completion of pending construction work, resolution of contingent liabilities, and maintenance of adequate debt service coverage ratios. The trust's ability to demonstrate operations without penalties or deductions remains crucial for rating stability.
