We limit our exposure to credit loss by generally placing cash in high credit quality financial institutions. Cash balances are maintained primarily at major financial institutions in the United States and a portion of which exceed the regulatory limit of $250,000 insured by the Federal Deposit Insurance Corporation (FDIC). We have not experienced any credit losses associated with its cash balances. Additionally, we have established guidelines regarding diversification of our investments and their maturities, which are designed to maintain principal and maximize liquidity.
