Now turning into Slide 13. In the fourth quarter we saw a continued strength in the development of our deposit franchise. Average deposits increase 10% year-over-year led by money market and demand deposits which were up $337 million and $73 million respectively. On a linked quarter basis, average deposits increased 5%. As Clay mentioned earlier, in the call, the private banking franchise on the West Coast made tremendous strides in 2014. Deposits, excluding CDs, increased 41% year-over-year in Southern California and 12% in the San Francisco Bay Area. CDs now make up 16% of the deposits based in Southern California, down from 24% at the end of 2013. In San Francisco Bay, CDs are 12% of total deposits down from 18% last year.
Slide 14 contains the financial information for the newly formed Boston Private Wealth Management segment. The third quarter 2014 data represents the Legacy Bank wealth management business. While the fourth quarter data shows the result for the combined Banyan and Legacy Wealth Management and Trust businesses. At the end of the third quarter Boston Private Wealth Management, at $13.3 million of revenue, $2.3 million of EBITDA, and $9.3 billion of assets under management. Peter Raimondi, CEO of Boston Private Wealth is working with our private banking leadership to accelerate cross-selling, further promote the Boston Private brand and further develop our distribution channels. Now I will turn you back to Clay.
