Question

In agents accounts accounts what items to consider while calculating operating expenses to

Answer 1

Sometimes, shares are allocated in exchange for non-cash consideration, most commonly when corporation A acquires corporation B for shares (new shares issued by corporation A). Here the share capital is increased to the par value of the new shares, and the merger reserve is increased to the balance of the price of corporation B.
In practice, the concept of "par value" has very little meaning, since shares usually represent a residual claim; they do not endow their owners with a claim toward any fixed sum of money. In some jurisdictions, share par values have been either abolished or made optional, so a corporation can issue shares having no par value. In that case, from an accounting perspective, all of the corporation's share capital is premium.
