Consider a firm called Tech Innovations Inc. whose capital structure is composed entirely of equity with a market value of $500 million. The firm is analyzing the potential benefits of introducing $200 million in debt into its capital structure. Under the Modigliani-Miller Proposition (M&M Proposition I without taxes), which states that the value of a firm is unaffected by its capital structure in a world without taxes, what will be the impact on the overall value of Tech Innovations Inc. after the introduction of debt?

Furthermore, consider that after introducing the debt, the firm's debt-to-equity ratio will change substantially and the firm believes it can leverage this change to maximize its overall value in a comprehensive capital structure strategy.
