As a result of the Transactions, we expect quarterly revenues to increase by over $7 billion year over year. We will also see an increase in expenses related to the increased scale and increases in expenses related to deploying our operating strategy and business model across the assets acquired in the Transactions. Launching Spectrum pricing and packaging and managing the all-digital transition in the Legacy TWC and Legacy Bright House footprint are key priorities and we expect to complete those initiatives by the end of 2018. Our Spectrum pricing and packaging simplifies our offers and improves our packaging of products, delivering more value to new and existing customers. Moving to an all-digital platform allows us to offer more HD channels and increase Internet speeds offered. Over time, we expect Adjusted EBITDA margins to increase as we benefit from Transaction synergies. By the end of 2016, we expect that our corporate organization, as well as our marketing, sales and product development departments, will be centralized. Field operations will be managed through eleven different regional areas, each designed to represent a logical combination of designated marketing areas and managed with largely the same set of field employees that were with the three companies prior to completion of the Transactions. Over a multi-year period, Legacy TWC and Legacy Bright House customer care centers will migrate to Charter's model of using virtualized, U.S.-based in-house call centers. We will focus on deploying superior products and service with minimal service disruptions as we integrate our information technology and network operations.

We believe that our enhanced product set combined with improved customer service has led to lower customer churn and longer customer lifetimes, allowing us to grow our customer base and revenue more quickly and economically. We believe that we will see similar results in the assets acquired in the Transactions as we deploy legacy Charter's
