Internet retailing giant Amazon.com Inc is looking to raise even more cash as it builds up it brand name and infrastructure. The Seattle-based company said Wednesday that it has filed a universal shelf registration with the Securities and Exchange Commission which will allow it to offer up to $2bn in various types of securities. The company says it made the filing to gain additional flexibility in accessing the capital markets.

It is free to offer the securities from time to time as the need for cash arises. In January it raised $1.25bn in a massive debt offering and has since paid $645m for Exchange.com Inc, Accept.com Inc and Alexa Internet Inc. It has also paid up for stakes in Pets.com Inc, Drugstore.com Inc and HomeGrocer.com Inc. The company is also seeking approval at a shareholders meeting this week for a massive increase in the number of authorized shares outstanding, from 300 million to 1.5 billion.
