The oil and gas industry does not distinguish between an asset and the purchase of shares when it designates its corresponding sales contract. In this sector, whether it is the purchase of assets or shares, the final agreement is called the Purchase and Sale Contract (PSA). An asset repurchase agreement (APA) is an agreement between a buyer and a seller that concludes the terms and conditions for the purchase and sale of a company`s assets.   It is important to note in an APA transaction that it is not necessary for the buyer to purchase all of the company`s assets. Indeed, it is customary for a buyer to exclude certain assets in an APA. The provisions of an APA may include payment of the purchase price, monthly payments, pawn and asset charges, closing condition, etc.  An APA is different from a share purchase agreement (SPA) in which business shares are also sold, ownership of assets and ownership of liabilities.  In an APA, the buyer must choose certain assets and avoid redundant assets. These facilities are broken down according to an APA schedule. The buyer in a SPA buys shares in the company. In this case, there is no need to revalue the transfer of ownership of the company. The APA is the legal mechanism for merging or acquiring businesses.  In addition to the flexibility to sell only certain assets and not the entire business, asset acquisition agreements generally contain detailed provisions regarding the transfer of liabilities from the seller.
