To obtain a loan, an organization sends a reasoned application to the bank with copies of constituent and other documents (charter, registration certificate, accounting reports, etc.) confirming the security of the loan repayment (feasibility study – feasibility study).

In conclusion, the bank employee describes the credit history of the enterprise, its business reputation, analysis of the financial condition, characteristics of the reliability of calculations and the possibility of fulfilling the planned indicators, a list of the main risks, draws conclusions about the advisability of issuing a loan and offers lending conditions.

Depending on the size of the loan, the decision to issue it is made either by the management of the credit department or by the credit committee. The decision to issue especially large loans is made by the Council of the bank or the General Meeting of Shareholders.

After the loan application is approved and the commercial bank decides to issue it, a loan agreement is drawn up and signed by both parties (Appendix 2). In the future, credit relations between the enterprise and the banking organization are built on the basis of the concluded loan agreement.
