    • Monthly Index Prices: Monthly index prices, along with 12-month rolling averages, for various indices. Monthly index prices are typically used in conjunction with monthly lease operating statements to determine the average differential to the indices.
    • First-Day-Of-The-Month Prices: Current oil and gas prices as defined by the SEC in its regulations, i.e., 12-month averages of first-day-of-the-month prices from various indices. For example:
