Net income for the three month period ended June 30, 1999 remained consistent
compared with the same period ending June 30, 1998. The increase in net income
for the six months ended June 30, 1999 compared to the same 1998 period reflects
increased gas deliveries due to colder temperatures during the 1999 heating
season. Partially offsetting the increase was the benefit resulting from a
one-time accounting change for property taxes in the first quarter of 1998. The
recognition of property tax expense was changed from expensing on a calendar
year basis to a fiscal year basis which resulted in a benefit of $18 million
($12 million after-tax). The decrease in earnings for the twelve months ended
June 30, 1999 compared to the same 1998 period reflects the change in accounting
for property taxes implemented in March 1998 as discussed above and an increase
in depreciation, partially offset by a decrease in the cost of gas.

GAS ISSUES

For a discussion of Consumers Gas Group operating issues, see Consumers Gas
Group Results of Operations-Uncertainties in CMS Energy's MD&A.

CASH POSITION, INVESTING AND FINANCING

OPERATING ACTIVITIES: Consumers Gas Group's cash requirements are met by its
operating and financing activities. Consumers Gas Group's cash from operations
is derived mainly from Consumers' sale and transportation of natural gas. Cash
from operations for the first six months of 1999 and 1998 totaled $221 million
and $139 million, respectively. The $82 million increase primarily reflects
increased earnings and depreciation, the absence of the 1998 cumulative effect
of the property tax accounting change, decreased inventory balances due to
increased sales, and increased accounts payable amounts due to the timing of
cash payments. Consumers Gas Group uses its


                                       1
   2
operating cash primarily to maintain and expand its gas utility transmission and
distribution systems, to retire portions of its long-term debt, and to pay
dividends.

INVESTING ACTIVITIES: Cash used in investing activities for the first six months
of 1999 and 1998 totaled $46 million and $52 million, respectively. The $6
million decrease in cash used primarily reflects decreased capital expenditures.

FINANCING ACTIVITIES: Cash used in financing activities during the first six
months of 1999 and 1998 totaled $174 million and $37 million, respectively. The
$137 million increase in cash used primarily reflects a decrease in the proceeds
from senior notes and an increase in the retirement of preferred stock,
partially offset by a decrease in the retirement of bonds and other long-term
debt.

OTHER INVESTING AND FINANCING MATTERS: Consumers has an agreement permitting the
sale of certain accounts receivable for up to $325 million. At June 30, 1999,
receivables sold totaled $266 million. Consumers Gas Group's attributed portion
of these receivables sold totaled $44 million. Accounts receivable and accrued
revenue in the Balance Sheets have been reduced to reflect receivables sold. For
further information, see CMS Energy's Note 3.

Consumers Gas Group expects that cash from operations and the ability to access
debt markets will provide necessary working capital and liquidity to fund future
capital expenditures, required debt payments, and other cash needs in the
foreseeable future. For further information regarding forward-looking

                     CONDENSED NOTES TO FINANCIAL STATEMENTS


1:   CORPORATE STRUCTURE

CMS Energy is the parent holding company of Consumers and Enterprises.
Consumers, a combination electric and gas utility company serving the Lower
Peninsula of Michigan, is the principal subsidiary of CMS Energy. For further
information regarding the businesses of CMS Energy, see the Notes to
Consolidated Financial Statements of CMS Energy included and incorporated by
reference herein.

CMS Energy has issued shares of Class G Common Stock. This class of Common Stock
reflects the separate performance of the gas distribution, storage and
transportation businesses conducted by Consumers and Michigan Gas Storage
Company, a subsidiary of Consumers (collectively, Consumers Gas Group). For
further information regarding the nature and issuance of the Class G Common
Stock, see Note 4 to the Consolidated Financial Statements of CMS Energy
included and incorporated by reference herein.

These Financial Statements and their related Notes should be read along with the
Financial Statements and Notes contained in the 1998 Annual Report of CMS Energy
that includes the Report of Independent Public Accountants, included and
incorporated by reference herein.


2:   EARNINGS PER SHARE AND DIVIDENDS

EARNINGS PER SHARE AND DIVIDENDS: Basic and diluted earnings per share for the
three month period ended June 30, 1999 and June 30, 1998, reflect the
performance of Consumers Gas Group. The earnings attributable to Class G Common
Stock and the related amounts per share are computed by considering the weighted
average number of shares of Class G Common Stock outstanding.

Earnings attributable to outstanding Class G Common Stock are equal to Consumers
Gas Group's net income multiplied by a fraction; the numerator is the weighted
average number of Outstanding Shares during the period, and the denominator is
the weighted average number of Outstanding Shares and Retained Interest Shares
during the period. The earnings attributable to Class G Common Stock on a per
share basis, for the six months ended June 30, 1999 and 1998, are based on 25.9
percent, 25.3 percent of the income of Consumers Gas Group, respectively.

In February and April 1999, CMS Energy declared and paid dividends of $.325 per
share on Class G Common Stock. In July 1999, the Board of Directors declared a
quarterly dividend of $.34 per share on Class G Common Stock, to be paid in
August of 1999. This represents an increase in the annualized dividend on Class
G Common Stock of $1.36 per share from the previous dividend of $1.30 (a 4.6
percent increase).


3:   SHORT-TERM FINANCINGS AND CAPITALIZATION

SHORT-TERM FINANCINGS: Consumers' short-term financings are discussed in the
Consolidated Financial Statements of CMS Energy Note 3 included and incorporated
by reference herein.


                                       8

Consumers generally manages its short-term financings on a centralized
consolidated basis. The portion of receivables sold attributable to Consumers
Gas Group at June 30, 1999 and 1998, is estimated by management to be $44
million and $40 million, respectively. Accounts receivable and accrued revenue
in the balance sheets have been reduced to reflect receivables sold. The
portions of short-term debt and receivables sold attributable to Consumers Gas
Group reflect the high utilization of short-term borrowing to finance the
purchase of gas for storage in the summer and fall periods. The allocation of
short-term financings and related interest charges to Consumers Gas Group
generally follows the ratio of gas utility assets to total Consumers' assets.
Additionally, the carrying costs for Consumers' sales of certain of its accounts
receivable under its trade receivable purchase and sale agreement generally are
allocated to Consumers Gas Group based on the ratio of customer revenues
contributed by Consumers' gas customers to total Consumers' revenue. As a result
of the centralized management of short-term financing, the amounts allocated to
Consumers Gas Group are further adjusted in both the seasonal gas inventory
build-up period (second and third quarters) and the high seasonal gas sales
period (first and fourth quarters) to more closely reflect the higher short-term
financing requirements of the inventory build-up period and conversely the lower
financing requirements during the higher sales periods. Management believes
these allocations to be reasonable.

CAPITAL STOCK AND LONG-TERM DEBT: Consumers Gas Group's capital stock and
long-term debt, including debt resulting from the sale of Trust Preferred
Securities, have been allocated based on the ratio of gas utility assets
(including common assets attributed to the gas utility segment) to total
Consumers' assets. Management believes these measurements are reasonable. For
information regarding the long-term debt and capital stock of CMS Energy and
Consumers, see Note 3 to the Consolidated Financial Statements of CMS Energy
included and incorporated by reference herein.


4:   COMMITMENTS AND CONTINGENCIES

CAPITAL EXPENDITURES: Consumers Gas Group estimates capital expenditures,
including new lease commitments, of $125 million for 1999, $130 million for
2000, and $130 million for 2001. These estimates include an attributed portion
of Consumers' anticipated capital expenditures for common plant and equipment.

For further information regarding commitments and contingencies directly
affecting Consumers Gas Group (including those involving former manufactured gas
plant sites), see the Consumers Gas Group Contingencies and Consumers Gas Group
Matters in CMS Energy's Note 2 included and incorporated by reference herein.

                    Report of Independent Public Accountants




To CMS Energy Corporation:

We have reviewed the accompanying balance sheets of CONSUMERS GAS GROUP
(representing a business unit of Consumers Energy Company and its wholly-owned
subsidiary, Michigan Gas Storage Company) as of June 30, 1999 and 1998, and the
related statements of income and common stockholders' equity for the
three-month, six-month and twelve-month periods then ended, and the related
statements of cash flows for the six-month and twelve month periods then ended.
These financial statements are the responsibility of the Company's management.

We conducted our review in accordance with standards established by the American
Institute of Certified Public Accountants. A review of interim financial
information consists principally of applying analytical procedures to financial
data and making inquiries of persons responsible for financial and accounting
matters. It is substantially less in scope than an audit conducted in accordance
with generally accepted auditing standards, the objective of which is the
expression of an opinion regarding the financial statements taken as a whole.
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the financial statements referred to above for them to be in
conformity with generally accepted accounting principles.

We have previously audited, in accordance with generally accepted auditing
standards, the balance sheet of Consumers Gas Group as of December 31, 1998, and
the related statements of income, common stockholders' equity and cash flows for
the year then ended (not presented herein), and, in our report dated January 26,
1999, we expressed an unqualified opinion on those statements. In our opinion,
the information set forth in the accompanying balance sheet as of December 31,
1998, is fairly stated, in all material respects, in relation to the balance
sheet from which it has been derived.
