It's possible that Seplat wants to carry out rigorous due diligence on Afren, which would explain the delay but it's more likely that the two groups are fighting over an appropriate purchase price. After all, Seplat will have to take on Afren's liabilities if it acquires the company, including Afren's $1.2bn debt pile. This means Seplat will have to seek approval from Afren's bondholders.
City analysts believe that if Afren fails to negotiate a deal, it will fail pretty quickly. Specifically, analysts believe that with oil prices at present levels, Afren's operations will only generate enough cash to cover its debt interest payments over the next 12 months.
