ANCHORAGE, Alaska (AP) — Two oil companies renewed a request for Alaska regulators to protect the financial information of Hilcorp Energy Co., in its proposed $5.6 billion purchase of BP Alaska assets in the state.

Hilcorp wants the Regulatory Commission of Alaska to shield its finances from public scrutiny during the proposed purchase, the Anchorage Daily News reported Tuesday.

The oil companies blacked out document sections related to Hilcorp's financial fitness and access to capital in a filing with the regulatory agency Monday.
