APPENDIX 12-B
. GOVERNMENT REGULATORY IMPACT MODEL (GRIM) OVERVIEW

12 -B.1 INTRODUCTION AND PURPOSE The purpose of the Government Regulatory Impact Model (GRIM) is to help quantify the impacts of energy conservation standards and other regulations on manufacturers. The basic mode of analysis is to estimate the change in the value of the industry or manufacturers(s) following a regulation or a series of regulations. The model structure also allows an analysis of multiple products with regulations taking effect over a period of time, and of multiple regulations on the same products. Industry net present value is defined, for the purpose of this analysis, as the discounted sum of industry free cash flows plus a discounted terminal value. The model calculates the actual cash flows by year and then determines the present value of those cash flows both without an energy conservation standard ( i.e. , the base case) and under different trial standard levels (TSLs) ( i.e. , the standards case). Output from the model consists of summary financial metrics, graphs of major variables, and, when appropriate, access to the complete cash flow calculation.

12 -B.2 MODEL DESCRIPTION The basic structure of the GRIM is a standard annual cash flow analysis that uses manufacturer selling prices, manufacturing costs, a shipments forecast, and financial parameters as inputs and accepts a set of regulatory conditions as changes in costs and investments. The cash flow analysis is separated into two major blocks: income and cash flow. The income calculation determines net operating profit after taxes. The cash flow calculation converts net operating profit after taxes into an annual cash flow by including investment and non-cash items. Below are definitions of listed items on the printout of the output sheet of the GRIM. (1) Unit Sales: Total annual shipments for the industry were obtained from the National Impact Analysis Spreadsheet; (2) Revenues: Annual revenues - computed by multiplying products’ unit prices at each efficiency level by the appropriate manufacturer markup; (3) Labor: The portion of cost of goods sold (COGS) that includes direct labor, commissions, dismissal pay, bonuses, vacation, sick leave, social security contributions, fringe, and assembly labor up-time; (4) Material: The portion of COGS that includes materials;12-B

(5) Overhead: The portion of COGS that includes indirect labor, indirect material, energy use, maintenance, depreciation, property taxes, and insurance related to assets. While include d in overhead, the depreciation is shown as a separate line item; (6) Depreciation: The portion of overhead that includes an allowance for the total amount of fixed assets used to produce that one unit. Annual depreciation computed as a percentage of COGS. While included in overhead, the depreciation is shown as a separate line item; (7) Stranded Assets: In the year the standard becomes effective, a one time write-off of stranded assets is accounted for; (8) Standard SG&A: Selling, general, and administrative costs are computed as a percentage of Revenues (2) ; (9) R&D: GRIM separately accounts for ordinary research and development (R&D) as a percentage of Revenues (2) ; (10) Product Conversion Costs: Product conversion costs are one-time investments in research, development, testing, marketing, and other costs focused on making products designs comply with the new energy conservation standard. The GRIM allocates these costs over the period between the standard’s announcement and compliance dates; (11) Earnings Before Interest and Taxes (EBIT): Includes profits before deductions for interest paid and taxes; (12) EBIT as a Percentage of Sales (EBIT/Revenues): GRIM calculates EBIT as a percentage of sales to compare with the industry’s average reported in financial statements; (13) Taxes: Taxes on EBIT (11) are calculated by multiplying the tax rate contained in Major Assumptions by EBIT (11)

. (14) Net Operating Profits After Taxes (NOPAT): Computed by subtracting Cost of Goods Sold ((3) to (6)) , SG&A (8) , R&D (9) , Product Conversion Costs (10) , and Taxes (13) from Revenues (2)

. (15) NOPAT repeated : NOPAT is repeated in the Statement of Cash Flows; (16) Depreciation repeated : Depreciation and Stranded Assets are added back in the Statement of Cash Flows because they are non-cash expenses; (17) Change in Working Capital : Change in cash tied up in accounts receivable, inventory, and other cash investments necessary to support operations is calculated by multiplying working capital (as a percentage of revenues) by the change in annual revenues. (18) Cash Flow From Operations : Calculated by taking NOPAT (15) , adding back non-cash items such as a Depreciation (16) , and subtracting the Change in Working Capital (17) ;12-B

(19) Ordinary Capital Expenditures: Ordinary investments in property, plant, and equipment to maintain and replace existing production assets, computed as a percentage of Revenues (2) ; (20) Capital Conversion Costs: Capital conversion costs are one-time investments in property, plant, and equipment to adapt or change existing production facilities so that new product de signs can be fabricated and assembled under the new regulation; The GRIM allocates these costs over the period between the standard’s announcement and compliance dates; (21) Capital Investment: Total investments in property, plant, and equipment are computed by adding Ordinary Capital Expenditures (19) and Capital Conversion Costs (20) ; (22) Free Cash Flow: Annual cash flow from operations and investments; computed by subtracting Capital Investment (21) from Cash Flow from Operations (18) ; (23) Terminal Value: Estimate of the continuing value of the industry after the analysis period. Computed by growing the Free Cash Flow at the beginning of 2045 at a constant rate in perpetuity; (24) Present Value Factor: Factor used to calculate an estimate of the present value of an amount to be received in the future; (25) Discounted Cash Flow: Free Cash Flows (22) multiplied by the Present Value Factor (2 4) . For the end of 2043, the discounted cash flow includes the discounted Terminal Value (2 3) ; and (26) Industry Value thru the end of 2043 : The sum of Discounted Cash Flows (25)
