Capital increase understanding

I have trouble to understand the interest of participating in this capital increase.

I understand I am entitled to 2500 right (code A4L1) (the same amount of share I own code A4L) which will allow me to buy 500 shares of the increase.

I also understand that the price at which I will be allowed to buy the shares is 3.

• Is the above correct ?
• What is the nominal value for ?
• I believe in this company. But what should I take care of ?

Market for this value:

We would like to inform you that as a shareholder in Allterco AD, BSE
stock exchange code A4L, you are entitled to participate in the
capital increase procedure of the company that is currently underway.
In this regard, you have received 2500 financial instruments called

• Number of shares before the increase: 15,000,000;
• Number of issued rights: 15,000,000;
• Number of shares offered for subscription: 3,000,000;
• Nominal value of the shares: BGN 1.00;
• Issue value of the shares: BGN 3.00;
• Exchange code of the issued rights: A4L1
• Ratio between the issued rights and the new shares: right / shares: 5/1;

Each person may subscribe at least 1 new share and at most such number
of shares, which is equal to the number of acquired and / or owned
rights, divided by 5.

• Starting date for trading of the rights and for subscription of shares: 08.10.2020;
• Closing date for trading the rights on the stock exchange: 19.10.2020;
• Deadline for submission of applications to Karoll AD for subscription of shares with rights purchased within the term for

The commission for trading in Allterco’s rights is the standard
