%MAC = Current Inventory/MAC

------------------------------------

%MDIQ Calculation

If the %MAC is < 100% and > 0%

then use the FORMULA to find the %MDIQ (1)

FORMULA (2,3):

%MDIQ = 100.0 - (%MAC * 1.0111774) + (%MAC^2 * 0.0051126)

------------------------------------

ADIQ Calculation (4)

ADIQ = (%MDIQ/100) * MDIQ

Round to the nearest whole Dekatherm (an integer)

------------------------------------

Notes: (1) The formula applies only when inventory is < than MAC and

> 0. If inventory is > or = to MAC, then set ADIQ = 0.

If inventory is < or = 0, set ADIQ = MDIQ.

(2) In the context of this formula, the %MAC and %MDIQ values

are taken as whole numbers, and not as decimal only

numbers (i.e. if the value is 40% use 40.0 not .40, or if

it is 36.1234% use 36.1234 not 0.361234).

(3) The coefficients are entered with seven decimal places.

The table is calculated with seven decimal places, and

then rounded for display purposes.

(4) All calculations are initially performed utilizing seven

decimal places. The final ADIQ, however, is rounded to

the nearest whole number.
