As of March 31, 2020, the balance of construction in progress was $63.3 million, of which $50.2 million was related to our buildings in our new Dingxing and Kazuo locations, $3.6 million was for manufacturing equipment purchases not yet placed in service and $9.5 million was for our construction in progress for our other consolidated subsidiaries. As of December 31, 2019, the balance of construction in progress was $61.8 million, of which $48.8 million was for our buildings in our new Dingxing and Kazuo locations, $3.4 million was for manufacturing equipment purchases not yet placed in service and $9.6 million was for our construction in progress at our other consolidated subsidiaries.

We reviewed our estimates of the useful lives of our property, plant and equipment. As a result of the review, we determined a portion of our manufacturing equipment was lasting longer than the estimate previously established for the respective useful lives. Where appropriate, we extended the useful life of the manufacturing equipment in our accounting records. In addition, the useful life of our buildings located in China was extended to better align with industry standards. The changes in our estimate of the useful life, effective January 1, 2020, were made in order to remain consistent with US GAAP regarding management estimates. The effect of the change in the useful lives decreased our manufacturing costs by approximately $0.3 million and decreased our basic and diluted net loss per share by approximately $0.01 for the quarter ended March 31, 2020 as a result of lower depreciation expense.
