        What’s really important to you—today and for the long term? UBS Wealth Way starts with questions and discussions that can help you organize your financial life into three key dimensions: Liquidity—to help provide cash flow for short-term expenses, Longevity—for longer-term needs and Legacy—for needs that go beyond your own.

Legacy. strategies that UBS Financial Services Inc. and our Financial Advisors can use to assist clients in exploring and pursuing their wealth management needs and goals over different time frames. This approach is not a promise or guarantee that wealth, or any financial results, can or will be achieved. All investments involve the risk of loss, including the risk of loss of the entire investment. Time frames may vary. Strategies are subject to individual client goals, objectives and suitability.
