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.

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 is commonly and naturally found in soil, plants, and water. Many of the plants that our vitamins and nutrients are sourced from absorb and bind small amounts of elements such as lead from the surrounding soil and water. Even the herbs we use, which are grown organically or wild in nature, do this as well. No lead or other such substances are added to any of our products.
