c) Costs of compensation for site clearance and relocation according to competent state agencies’ decision; costs of reinforcement of work foundations;

d) Project management costs including costs of organizing and implementing project management from establishment of the project till the project is completed and put into operation;

dd) Investment and construction costs including costs of hiring consultants on survey, design, construction supervision, examination and verification and other relevant costs;

e) Other costs including working capital during test run of the plant, loan interests, costs of getting loans during the construction period and other necessary costs;

g) Provisional costs including costs of additional quantity of work and provision for slippage in prices during the construction period;

4. Financial discount rate i (%) applying pre-tax nominal Weighted Average Cost of Capital is calculated with the following formula:

Where:

D: Proportion of loan in total investment as prescribed in Appendix 1 hereof (%);

E: Proportion of contributed capital in total investment as prescribed in Appendix 1 hereof (%);

n: Economic life of Standard Power Plant as prescribed in Appendix 1 enclosed herewith (year);

n_D: Average time of paying debt prescribed in Appendix 1 enclosed herewith (year);

R_d: Loan interest determined according to Point a of this Clause (%);

r_e: Pre-tax rate of return over contributed capital determined according to Point b of this Clause (%);

a) Loan interest r_D (%) is calculated on the basis of Weighted Average Cost of Capital interest rate of local and foreign currency loans with the following formula:

r_d = D_F x r_d,F + D_D x r_d,D

Where:

D: Proportion of foreign currency loan in total loan as prescribed in Appendix 1 hereof (%);

D: Proportion of local currency loan in total loan as prescribed in Appendix 1 hereof (%);

r_dF: Foreign currency loan interest rate is determined by adding average value of US dollar interest rate swap (10-year term) in 36 consecutive months preceding to the year of issuance of cost frame on London interbank market (LIBOR swaps) and annual average bank service fee, guarantee fee and relevant tax (3%) or promulgated by the Ministry of Industry and Trade in the electricity generation cost frame (%/year).

r_d,D: Local currency loan interest rate is determined by adding average Vietnam dong deposit rate (12-month term) intended for individuals in five consecutive years preceding to the year of issuance of cost frame, determined at September 30 annually, by four commercial banks (Joint stock commercial Bank for Foreign Trade of Vietnam, Vietnam Joint Stock Commercial Bank for Industry and Trade, the Joint Stock Commercial Bank for Investment and Development, Vietnam Bank for Agriculture and Rural Development, or lawful successors to these banks) and annual average bank service fee (3.5%) or promulgated by the Ministry of Industry and Trade in the electricity generation cost frame (%/year).
