ENTERGY MISSISSIPPI, INC.  MANAGEMENT'S FINANCIAL DISCUSSION AND ANALYSIS Results of Operations Net Income 2008 Compared to 2007 Net income decreased $12.4 million primarily due to higher other operation and maintenance expenses, lower other income, and higher depreciation and amortization expenses, partially offset by higher net revenue.2007 Compared to 2006 Net income increased $19.8 million primarily due to higher net revenue, lower other operation and maintenance expenses, higher other income, and lower interest expense, partially offset by higher depreciation and amortization expenses.
Net Revenue 2008 Compared to 2007 Net revenue consists of operating revenues net of: 1) fuel, fuel-related expenses, and gas purchased for resale, 2) purchased power expenses, and 3) other regulatory charges.
Following is an analysis of the change in net revenue comparing 2008 to 2007.
## Table 0 ##
The Attala costs variance is primarily due to an increase in the Attala power plant costs that are recovered through the power management rider.
The net income effect of this recovery in limited to a portion representing an allowed return on equity with the remainder offset by Attala power plant costs in other operation and maintenance expenses, depreciation expenses, and taxes other than income taxes.
The recovery of Attala power plant costs is discussed further in "Liquidity and Capital Resources - Uses of Capital" below.
The rider revenue variance is the result of a storm damage rider that became effective in October 2007.
The establishment of this rider results in an increase in rider revenue and a corresponding increase in other operation and maintenance expense for the storm reserve with no effect on net income.
The base revenue variance is primarily due to a formula rate plan increase effective July 2007.
The formula rate plan filing is discussed further in "State and Local Rate Regulation" below.
The reserve equalization variance is primarily due to changes in the Entergy System generation mix compared to the same period in 2007.
PRUDENTIAL FINANCIAL, INC.  Notes to Consolidated Financial Statements 11.
SHORT-TERM AND LONG-TERM DEBT Short-term Debt Short-term debt at December 31, is as follows:
## Table 1 ##
(1) Assets under set-off arrangements represent a reduction in the amount of note payables included in short-term debt, relating to an arrangement where valid rights of set-off exist and it is the intent of both parties to settle on a net basis under legally enforceable arrangements.
The weighted average interest rate on outstanding short-term debt, excluding the current portion of long-term debt and convertible debt, was approximately 4.2% and 2.2% at December 31, 2005 and 2004, respectively.
At December 31, 2005, the Company had $3,845 million in committed lines of credit from numerous financial institutions, of which $3,832 million were unused.
These lines of credit generally have terms ranging from one to five years.
The Company issues commercial paper primarily to manage operating cash flows and existing commitments, to meet working capital needs and to take advantage of current investment opportunities.
At December 31, 2005 and 2004, a portion of commercial paper borrowings were supported by $3,000 million and $2,500 million of the Company’s existing lines of credit, respectively.

On November 16, 2005, Prudential Financial issued $2.0 billion in floating rate convertible senior notes, convertible by the holders at any time after issuance into cash and shares of Prudential Financial’s Common Stock.
The conversion price, initially $90 per share, is subject to adjustment upon certain corporate events, such as certain changes in control or increases to the Company’s dividends above the current $0.78 annual dividend per share.
The conversion feature requires net settlement in shares; therefore, upon conversion, a holder would receive cash equal to the par amount of the notes surrendered for conversion and shares of Prudential Financial, Inc.  Common Stock only for the portion of the settlement amount in excess of the par amount, if any.
The convertible notes are redeemable by Prudential Financial on or after May 20, 2007, at par plus accrued interest.
Holders may require Prudential Financial to repurchase the convertible notes, at par plus accrued interest, on May 15, 2007 or on November 15, 2010, 2015, 2020, 2025, and 2030.
The Company has entered into a registration rights agreement with the investors in the convertible debt, which requires that the Company attempt to register the convertible debt and the shares into which the debt is convertible for resale.
In the event the Company is unable to register the shares, or is unable to maintain the effectiveness of such registration, the Company could be required to pay liquidated damages of 0.25% applied to the par amount of the notes for each interest period such default continues.
The interest rate on the convertible notes is a floating rate equal to 3-month LIBOR minus 2.76%, to be reset quarterly.
For the period from November 16, 2005, the date of issuance, to February 15, 2006, the first interest payment date, the interest rate is 1.57%.
