In addition, the Company uses other derivative contracts to manage the foreign exchange impact of certain debt issuances.
At December 31, 2010, the Company’s overall weighted average interest rate for long-term debt was 3.53% on a contractual basis and 2.78% including the effects of derivative contracts.

MORGAN STANLEY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) ?
Interest rate curve—the term structure of interest rates (relationship between interest rates and the time to maturity) and a market’s measure of future interest rates at the time of observation.
An interest rate curve is used to set interest rate and foreign exchange derivative cash flows and is a pricing input used in the discounting of any OTC derivative cash flow.  ?
Price / Book ratio—the ratio used to compare a stock’s market value with its book value.
The ratio is calculated by dividing the current closing price of the stock by the latest book value per share.
This multiple allows comparison between companies from an operational perspective.  ?
Price / Earnings ratio—the ratio used to measure a company’s equity value in relation to its earnings.
The ratio is calculated by dividing the equity value per share by the latest historical or forward-looking earnings per share.
The ratio results in a standardized metric that allows comparison between companies, after also considering the effects of different leverage ratios and taxation rates.  ?
Volatility—the measure of the variability in possible returns for an instrument given how much that instrument changes in value over time.
Volatility is a pricing input for options and, generally, the lower the volatility, the less risky the option.
The level of volatility used in the valuation of a particular option depends on a number of factors, including the nature of the risk underlying that option (e. g. , the volatility of a particular underlying equity security may be significantly different from that of a particular underlying commodity index), the tenor and the strike price of the option.  ?
Volatility skew—the measure of the difference in implied volatility for options with identical underliers and expiry dates but with different strikes.
The implied volatility for an option with a strike price that is above or below the current price of an underlying asset will typically deviate from the implied volatility for an option with a strike price equal to the current price of that same underlying asset.
