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.
If dishes do contain lead, it's important to never cook or microwave food in them (bean pots from Mexico, called ollas or casuelas, often have lead glazes), and to avoid storing acidic foods like tomato sauce, citrus fruit, soy sauce, alcohol, or coffee in them.
