A paper coating pigment manufactured from kaolin crude containing minor amounts of minerals is used in lightweight coated and ultra-lightweight coated applications. The pigments comprise a phyllosilicate assemblage of minerals that yield a final pigment MgO content ranging between 0.04 to 0.3 weight
A paper coating pigment manufactured from kaolin crude containing minor amounts of minerals is used in lightweight coated and ultra-lightweight coated applications. The pigments comprise a phyllosilicate assemblage of minerals that yield a final pigment MgO content ranging between 0.04 to 0.3 weight percent and a K2O content ranging between 0.12 and 0.8 weight percent based on the dry weight of the kaolin crude. The mica in the pigment product is 1.0% to 6.7% by weight, and smectite is 1.2% to 9.1% by weight of the kaolin. The presence of these weight percentages can be identified by a shape factor of 15 or greater. The viscous clay content of the feed to produce the pigment product is between 70 and 100 weight percent based on the dry weight of the kaolin clay. The pigment has a shape factor ranging between 35 and 60 or greater, and greater than 80% by weight of the particle are less than 2 microns, and greater than 12% are less than 0.25 microns.

The method of claim 1, wherein the step of inputting application variables includes inputting transaction expenses, income tax rates and moving average values for said security of interest. 4. The method of claim 1, wherein the step of interactively utilizing said computer system includes utilizing said computer system to compute a Sharpe Ratio, a beta ratio and standard deviation for said security of interest. 5. The method of claim 1, wherein the step of outputting includes outputting an internal rate of return on the capital invested in said security of interest, an internal rate of return on the income from said security of interest, and the average cost of said security of interest. 6. The method of claim 1, wherein said step of providing said computer system includes providing a computer system interconnected to the Internet, wherein said computer system include means for facilitating Internet users to remotely input application content variables, and obtaining investment and performance information. 7. A computer program product comprising a computer useable medium having embedded therein a computer readable program code comprising a method for analyzing performance of financial securities consistent with a long-term investment strategy, the method utilizing a computer system having a computer processor programmed to electronically process data and display information, the processor being electronically connected to input and output devices and to computer networks, the method comprising the steps of: providing said computer system, obtaining and inputting into said computer system, application content variables comprising prices of securities and incomes from said securities, said securities being securities of interest for investment, said securities being identifiable by a security symbol, inputting into said computer system, investment parameters comprising a security symbol of interest, said security symbol of interest being included in securities in said application content variables, investment amount in said security of interest, investment frequency, investment term, and performance duration time period pertaining to an investor's preference for analyzing security's performance, interactively utilizing said computer system, in conjunction with said investment parameters and said application content variables, calculate an internal rate of return for said security utilizing the formula: MV=ΣAi(1+R)Ti where, MV=market value of an investment in said securities at the end of said performance duration time period, said market value being equal to the cumulative number of securities purchased multiplied the price of said securities at the end of said performance duration time period, Ai=cash flows within said performance duration time period comprising investments, withdrawals, dividends and cost of investments including transaction costs, commissions and other expenses associated with said investments, Ti=a ratio of the total number of days in said performance duration time period that said cash flow Aihas been in, or out of, a portfolio, and where Tiis calculated from: Ti=(D-Di)/D and where D is the total number of days in said performance duration time period and Diis the number of days since the beginning of said performance duration time period in which said cash flow has occurred, and outputting on said output devices, investment and performance information comprising market value of said investment, time-weighted internal rate of return of said investment, cumulative investment amount and cumulative number of shares purchased at th
