Outline of the Presentation


I. The System of National Accounts

-consists of a coherent, consistent and integrated set of macroeconomic accounts, balance sheets and tables based on a set of internationally agreed concepts, definitions, classifications and accounting rules;

- use for monitoring the behavior of the economy, for macro-economic analysis, for economic policy formulation and decision making; as well as for international comparison.



-basically, the SNA records all economic transactions, the flows and stocks in the country including its relationships with the rest of the world (ROW)

- The SNA generates macro-economic aggregates namely:

GROSS DOMESTIC PRODUCT GROSS NATIONAL INCOME


In the SNA, transactors are economic units are grouped into producing industry/sector namely:

INDUSTRY – Agriculture, Industries, Services SECTOR

Financial Corporations Non-financial Corporations General Government Households including the Non-Profit

Institutions Serving Households

National Statistical Coordination Board



II. Measuring the Electricity, Gas and Water

SCOPE and COVERAGE

Electricity, Gas and Water as an Industry

Electricity - generation, transmission and distribution of electricity for sale to households, industrial, commercial and other users.

Gas - manufacture and distribution of gaseous fuels through a system of mains to households, industrial, commercial and other users.

Water - collection, purification and distribution of water to household, industrial, commercial or other users.

Note: Scope and Coverage are based from the Philippine Standard Industrial Classification (PSIC) following the ISIC



SCOPE and COVERAGE

Excluded are:

- Operation of irrigation works in agriculture.- Electricity generation by manufacturing, mining

and other industries for own use

Note: Scope and Coverage are based from the Philippine Standard Industrial Classification (PSIC) following the International Standard Industrial Classification (ISIC)


Electricity

A. National Power Corporation

- Financial Statements

- Electricity produced and sold (peso&kwh)

- Other key performance indicators

B. Manila Electric Company and National Electrification Administration

- Financial Statements

- Electricity purchased and sold (peso&kwh)

- Other key performance indicators


DATA AND DATA SOURCES


Electricity

C. Energy Regulatory Commission

- Effective Selling Rates

D. National Statistics Office

- Quarterly and Annual Survey and Census on

Philippine Business and Industry

Gross revenue

Employment

Compensation

Other key performance indicators



Water

Manila Water Corporation, Inc.

Maynilad Water System, Inc.

Local Water Utilities Administration

National Water Regulatory Board

Financial Statements

Water production and sales statisticS

Effective selling rates

Other key performance indicators



a. Gross Output (GO) Revenue from main activity

Changes in Inventory of finish products and work in progress

Industrial and non-industrial services done for others

Trade margin

Changes in inventory of goods for resale

Other revenue

Fixed assets produced on own account

ESTIMATION METHODOLOGY


Benchmark Estimation


b. Intermediate Consumption (IC) Materials and supplies purchased

Fuels purchased

Supplies and fuels used

Electricity purchased

Industrial and non-industrial services done by others

Other costs




c. Gross Value Added (GVAcur) at current prices

Compensation Consumption of Fixed Capital Taxes on Products and Imports Operating surplus

d. Gross Value Added Ratio (GVAR)

GVAR = GVAcur / GO




e. Gross Value Added (GVAcon) at constant prices

GVA cons = GVAcur / Price Index

where:

Price Index = Constructed composite input

price indices based on the prices of the major

inputs (oil, fuel, diesel, electricity, machines and

machine parts)




B. Quarterly Estimation

a. Gross Value Added (GVAcur) at current prices

GVA1cur = (GO1 / GOo) x GVAocur

where:

GVA1cur= present GVA

GVAocur= previous GVA (the same quarter of the previous year)

GO1 = present GO

Goo = previous GO (the same quarter of the previous year)



b. Gross Value Added (GVAcon) at constant prices

GVA1con = GVAcur / WESR

where:

GVA1con = present GVA

GVAcur = present GVA at current prices

WESR = weighted effective selling rates


B. Quarterly Estimation


a. Implicit Price Index (IPIN)

IPIN = (GVA cur /GVA con) x 100

b. Inflation

= growth of the IPIN from the same period of the previous year

D. Price Indices

C. Annual Estimation

Gross Value Added at current and at constant prices

GVA = ∑ (quarterly GVA estimates)
