swap ratio
{{distinguish|Swap rate}}
In corporate finance, the swap ratio is an exchange rate of the shares of the companies that undergo a merger;
see Stock swap and {{slink|Mergers and acquisitions #Stock}}.
The swap ratio determines the control that each group of shareholders of the companies shall have over the combined firm: essentially a function of the relative value of the strategic and financial results of the two companies. This ratio is thus calculated as a function of the valuation of the various assets and liabilities of the merging companies.
