What is the 'Information Ratio - IR'. The information ratio (IR) is a ratio of portfolio returns above the returns of a benchmark -- usually an index -- to the volatility of those returns. The information ratio (IR) measures a portfolio manager's ability to generate excess returns relative to a benchmark but also attempts to identify the consistency of the investor.
Prop 65 lists of over 900 substances, including lead, that businesses are required to warn consumers about. Lead is a natural element in soil, so it can be found in trace amounts in anything that is grown or drawn from the earth â including fruits, vegetables, and, of course, Earthpaste.
Lead used to be very common in gasoline and house paint in the U.S. Children living in cities with older houses are more likely to have high levels of lead. Although gasoline and paint are no longer made with lead in them, lead is still a health problem. Lead is everywhere, including dirt, dust, new toys, and old house paint. Unfortunately, you cannot see, taste, or smell lead.
