Exhibit A

**********************

We operate in the multi-family office registered investment adviser channel of private wealth management, the fastest growing sector of the market according to Cerulli Associates. The aggregate assets of managers in this channel have nearly doubled over the last five years, largely due to market share gains, primarily from large financial institutions.

Our client relationships with ultra-high net worth individuals currently represent less than 1% of U.S. families with investable assets over $25 million. Our assets represent less than 5% of the $498 billion multifamily office (MFO)/registered investment adviser (RIA) channel, which, according to data from Cerulli Associates, itself represents 10% of the estimated $4.8 trillion high net worth market.

Over the last 15 years, the number of households with over $5 million in net worth has grown at an annual rate of 11% per year. Cerulli Associates estimates that 90% of the $4.8 trillion high net worth market is at firms outside the MFO/RIA channel.

Cerulli Associates estimates that MFO/RIAs are the fastest growing firms in the wealth management industry. Assets have nearly doubled over the last five years as they have taken greater market share, primarily from large financial institutions. Assets managed by MFO/RIAs grew from 2006-2011 at a CAGR of 13.6% as compared with a 0.9% CAGR for all high net worth providers. Cerulli Associates further estimates that high net worth assets managed by MFO/RIAs will grow at a 15.7% CAGR from 2011 through 2015. We are an RIA which is also regarded as an MFO, and thus we are well positioned to benefit from the growth Cerulli Associates foresees.

Continuing our short-term growth strategy, we intend to establish offices in major wealth centers on the West Coast, in the Southwest and in the Midwest in order to be closer to both our clients and to prospective clients. The following chart identifies those U.S. cities which contain the greatest number of families with net worth of $30 million or more:
