Section 605.100 Accounting
Instruction 1
Accounting Instruction 1,
"General – Classification of Utilities," is deleted and replaced by
the following:
"A. For the purpose of applying the system of accounts
prescribed by the Commission, water utilities are divided into two classes, as
follows:
Class A – Utilities having annual water operating revenues of
$1,000,000 or more.
Class B – Utilities having annual water operating revenues of
less than $1,000,000.
B. This system of accounts applies to Class A utilities. Class B
utilities shall keep all the accounts of this system of accounts applicable to
their affairs. Class B utilities may, however, keep accounts for operating
revenues and operating expenses under the accounts of the condensed
classifications provided by this Part. (See Accounting Instruction 40.)
C. The class to which any utility belongs shall originally be
determined by the average of its annual water operating revenue for the last
three consecutive years. Subsequent changes in classification shall be made
when the annual water operating revenues for each of the three immediately
preceding years shall exceed $1,000,000 on a stand alone basis of the annual
water and sewer operating revenues.
D. Class B utilities desiring more detailed accounting may adopt
the accounts prescribed for Class A utilities. Class B utilities are not
required to comply with more detailed accounts than what otherwise may be their
case."
