BOT is the abbreviation of three English words, namely Build-Operate-Transfer.

BOT refers to the franchise granted by the government to private enterprises (including foreign enterprises) for a certain period of time, allowing them to finance the construction and operation of specific public infrastructure, and allowing them to repay loans, recover investment and earn profits by charging users or selling products; When the concession period expires, the infrastructure will be handed over to the government free of charge.

In the field of international financing, BOT not only includes the process of construction, operation and handover, but also is a project financing method with limited recourse.

BOT project financing mode is a project financing mode developed under the background of the world economic recession and the third world debt crisis, which is mainly used for public infrastructure construction. The so-called project financing refers to the financing based on the credit of the project itself, and the project financing corresponds to enterprise financing. Banks can only rely on project assets or project income to recover the loan principal when financing through project financing.

And interests. In this kind of financing, the risks undertaken by banks are far greater than those of corporate financing. If the project fails, the bank may not be able to recover the loan principal and interest, so the project results are often complicated. In order to realize this complex structure, a lot of preliminary work needs to be done, and the preliminary cost is high.

The above concept of recovering principal and interest only by project assets or project income is a concept without recourse. In the actual BOT project operation process, the shareholders of the government or the project company provide certain support for the project to a certain extent, and the bank's recourse to the shareholders of the government or the project company is limited to the extent of this support, rather than unlimited recourse, so the project financing is often limited recourse financing. Because BOT project has the characteristics of limited recourse, the debts of BOT project are not included in the balance sheet of the project company's shareholders, so that the project company's shareholders can raise construction funds for more projects, so it is welcomed by equity bidders and widely used.
