Kohlberg Kravis Roberts has warned investors it may not be able to find financing for all of its planned leveraged buyouts even as the firm's slew of megadeals take up more than one-third of the global $330bn (€242.5bn) leveraged loan pipeline.

KKR said in an amended filing for its initial public offering that financing for the firm's completed and pending deals is still conditional. The private equity firm said it has $57bn in completed acquisitions and $84bn of pending deals, for a total of $140bn.
