Transaction costs represent costs related to the planning and execution of the Starwood Combination, primarily for financial advisory, legal, and other professional service fees. Employee termination costs represent charges, or adjustments to prior period charges, for employee severance, retention, and other termination related benefits. Integration costs primarily represent integration employee salaries and share-based compensation, change management consultants, and technology-related costs. Merger-related interest expense in the 2016 first half reflects costs that we incurred for a bridge term loan facility commitment related to the Starwood Combination.

In connection with the Starwood Combination, we initiated a restructuring program to achieve cost synergies from our combined operations. We did not allocate costs associated with our restructuring program to any of our business segments. The following table presents our restructuring reserve activity during the 2017 first half:
