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 can be found in all parts of our environment â the air, the soil, the water, and even inside our homes. Much of our exposure comes from human activities including the use of fossil fuels including past use of leaded gasoline, some types of industrial facilities, and past use of lead-based paint in homes.
