About white knight

In business, a white knight is a friendly investor that acquires a corporation at a fair consideration with support from the corporation's board of directors and management. This may be during a period while it is facing a hostile acquisition from another potential acquirer or it is facing bankruptcy. White knights are preferred by the board of directors and/or management as in most cases as they do not replace the current board or management with a new board, whereas, in most cases, a black knight will seek to replace the current board of directors and/or management with its new board reflective of its net interest in the corporation's equity.
