If the costs have been taken as intangible assets, they will be amortized at 220 percent as intangible asset costs before tax.

Taking a 30-year fully amortized loan of 1 million yuan for example, the monthly payment will shrink about 207 yuan as the interest rate is lowered from 4.6 percent to 4.25 percent, according to Yan's calculation.

Taking the 30-year 1 million yuan ($158,100) fully amortized mortgage for example, the monthly payment would be reduced by about 30 yuan from 5,156 yuan, when the LPR was set at 4.65 percent, said Yan Yuejin, director of Shanghai-based E-house China Research and Development Institution.

CMC's investment will be amortized with electricity sales in the future, Meng said, adding that the station will contribute a total of 2 million euros in taxes to local and state governments.

Taking the 30-year 1-million-yuan ($157,637) fully amortized mortgage as an example, the monthly payment should be 5,156 yuan when the LPR was set at 4.65 percent.

If intangible assets are formed, they shall be amortized by 200 percent of the cost of intangible assets before tax from Jan 1, the statement said, adding that tax policies would look to encourage technology research and innovation.
