Context: The Alaska Permanent Fund Corporation manages the assets of both the Permanent Fund and other state investments, but spending Fund income is up to the Legislature. The Corporation is to manage for maximum prudent return, and not -- as some Alaskans at first wanted -- as a development bank for in-state projects. The Fund grew from an initial investment of $734,000 in 1977 to approximately $53.7 billion as of July 9, 2015. Some growth was due to good management, some to inflationary re-investment, and some via legislative decisions to deposit extra income during boom years. Each year, the fund's realized earnings are split between inflation-proofing, operating expenses, and the annual Permanent Fund Dividend.

Question: where does the permanent fund dividend come from?
Answer. the fund 's realized earnings
What step-by-step reasoning justifies that answer?
