Historic Pricing is a unit pricing method used to calculate the value of an asset using the last valuation point calculated. Historic pricing is used when the value of an asset does not update in real time because it is not a current value. This is appropriate when the valuation depends on events that have not occurred and may be recorded at different points in time. Historic pricing may be used when calculating the value of assets such as bonded assets or those that are valued on a cash flow basis.The process of determining the last valuation date is a critical part of valuing a company's assets. Historically, investors have used the previous valuation date to calculate the value of a company's assets. The valuation date is calculated by taking the company's total liabilities and dividing them by its total assets. If a company has a net asset value that does not change over time, historic pricing may not be needed. However, if the value of an asset does change over time, it is important to evaluate the value of each asset on an individual basis.
