3. SIGNIFICANT MATTERS

3.1 The details of and the reasons for the material changes in the major 
financial statement items and financial indicators of the Company

    Applicable       Not applicable

 1. Cash balance of the Company and its subsidiaries as at the end of the
    reporting period increased by approximately 89% over the beginning of the
    reporting period. This was mainly because of the increase in the borrowings
    of the Company and its subsidiaries;
 
 2. Notes receivables of the Company and its subsidiaries as at the end of the
    reporting period increased by approximately 39% over the beginning of the
    reporting period. This was mainly because of the increase in volume of
    notes receivables used by customers for settlement;
 
 3. Prepayments of the Company and its subsidiaries as at the end of the
    reporting period increased by approximately 47% over the beginning of the
    reporting period. This was mainly because of an increase in prepayments for
    purchase of fuel coal made by the Company and its subsidiaries;
 
 4. Other receivables of the Company and its subsidiaries as at the end of the
    reporting period increased by approximately 32% over the beginning of the
    reporting period. This was mainly because of the increase in subsidies
    receivable due to the inclusion of Shenzhen Datang Baochang Gas Power
    Generation Co., Ltd. in the consolidated financial statements;
 
 5. Construction materials of the Company and its subsidiaries as at the end of
    the reporting period increased by approximately 41% over the beginning of
    the reporting period. This was mainly because of an increase in the
    fundamental infrastructure materials purchased by the Company and its
    subsidiaries for the implementation of the development strategies;
 
 6. Other non-current assets of the Company and its subsidiaries as at the end
    of the reporting period increased by approximately 27 times over the
    beginning of the reporting period. This was mainly because of an investment
    of RMB2,000 million as a result of the implementation of a trust plan by
    the Company;
 
 7. Advances from customers of the Company and its subsidiaries as at the end
    of the reporting period increased by approximately 87% over the beginning
    of the reporting period. This was because of the increases in advances from
    customers received by the Company's coal mining enterprises from coal
    sales;
 
 8. Dividends payables of the Company and its subsidiaries as at the end of the
    reporting period decreased by approximately 47% over the beginning of the
    reporting period. This was mainly because some of the dividends were paid
    during the current period;
 
 9. Operating costs of the Company and its subsidiaries for the current
    reporting period increased by approximately 234% over the corresponding
    reporting period of the previous year. This was mainly because of increased
    freight charges for railway transport borne by the Company's coal mining
    enterprises during the sales process;
 
10. Finance costs of the Company and its subsidiaries for the current reporting
    period increased by approximately 37% over the corresponding reporting
    period of the previous year. This was mainly because of the combined
    effects of an increase in borrowings and a rise in interest rates;
 
11. Investment income of the Company and its subsidiaries for the current
    reporting period increased by approximately 170% over the corresponding
    reporting period of the previous year. This was mainly because of the
    profit growth from the Company's associates (jointly-controlled entities),
    and the trust income received during the current reporting period;
 
12. Non-operating income of the Company and its subsidiaries for the current
    reporting period increased by approximately 183% over the corresponding
    reporting period of the previous year. This was mainly because of an
    increase in government subsidies received during the current reporting
    period;
 
13. Income tax expense of the Company and its subsidiaries for the reporting
    period increased by approximately 107% over the corresponding period of the
    previous year. This was mainly because of the increase in income tax
    expense as a result of the increase in profits of the Company and its
    subsidiaries;
 
14. Consolidated net profit attributable to equity holders of the Company
    increased by approximately 344.34% over the corresponding reporting period
    of the previous year. This was mainly due to the increases in average
    tariff of on-grid power and on-grid power generation;
 
15. Net cash flows generated from investing activities of the Company and its
    subsidiaries for the current reporting period decreased by approximately
    87% over the corresponding reporting period of the previous year. This was
    mainly because of an increase in capital expenditures for the current
    reporting period over the corresponding period of the previous year;
 
16. Net cash flows generated from financing activities of the Company and its
    subsidiaries for the current reporting period increased by approximately
    183% over the corresponding reporting period of the previous year. This was
    mainly because of an increase in bank loans.
