the fund 's realized earnings
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.

The National Football League (NFL) regular season begins the weekend after Labor Day in early September and ends in December or early January. It consists of 256 games, where each team (32 total) plays 16 games during a 17-week period. Since 2012, the NFL schedule generally has games in one of five time slots during the week. The first game of the week is played on Thursday night, kicking off at 8: 25 PM (ET). The majority of games are played on Sunday, most kicking off at 1: 00 PM (ET), some late afternoon games starting at 4: 05 or 4: 25 PM (ET). Additionally, one Sunday night game is played every week at 8: 30 PM (ET). One Monday night game then starts at 8: 30 PM (ET) every week with the exception of the first week of the regular season, in which two Monday night games are played back-to-back (the second game always occurring on the West coast), as well as the last week of the season, in which no Monday night game is held. In addition to these regularly scheduled games, there are occasionally games at other times, such as a Saturday afternoon or evening, or the annual Thanksgiving Day games in which three games are played. During the final week of the regular season, all games are held on Sunday.
