Year Start Sequence

1. Calculate BRP base changes
	* May have increased due to mobilizations
	* May have decreased due to the following:
		+ For each point of Germany’s BRP base above 150, it must receive 2 BRPs from conquest of minor countries; any additional points in Germany’s BRP base are lost
		+ Japan loses 1 point to its BRP base for each air factor (or 3 NAS units) uninverted while under an air oil effect
		+ While loss of a Key Economic Area does not reduce a country’s BRP base, it does reduce its construction limit by the appropriate amount
		+ BRP deficits from the previous year (see below under BRP Base Growth)
		+ BRP base may not drop below 0
2. BRP Base Growth: Part of the unspent BRPs from the previous year are carried over
	* Each major country takes the BRPs remaining from the previous year and multiplies the amount by its BRP growth rate percentage for that year; this amount is carried over to the next year, and the remainder is put towards Research Points
		+ BRP growth rate for unspent BRPs is reduced by 5% for each oil counter below maximum
		+ If there is a BRP deficit from the previous year, it is multiplied by the country’s BRP growth rate and the result is **permanently deducted** from the country’s BRP base; while the remainder is taken from the new year’s BRP totals
3. BRP Totals: Other BRP income is calculated for a final total for the new year
	* BRP Gains
		+ Conquered major powers
		+ Captured key economic areas
		+ Colonies and conquered minor countries
		+ Minor countries that are allies, associated, or economically penetrated
		+ Captured or controlled ICs
		+ BRP Losses
			- The remainder of BRP deficits from the previous year, after BRP base deductions
			- Originally controlled Key Economic Areas controlled by another alliance faction
				* Note that BRP gains/losses that occur during the player turns due to conquests, diplomacy, etc are prorated at different points of the YSS or player turns as indicated.
		+ **Any BRP gains from Axis conquests in the previous Winter phase are received now**
4. Construction Limits: BRP points available for Unit Construction this turn
	* 1/3rd of BRP base, rounded down
	* -1 for every 3 BRPs lost to Transport shortages, Strategic Bombings, and enemy units adjacent to mapboard boxes
		+ Indian and Australian BRPs lost to Strategic Bombing lower Britain’s Construction Limit as well
5. Allot DPs.
	* Basic Allotments:
		+ Germany, Britain, Russia: 3
		+ Italy, France: 2
		+ US: 1 per every 10 USAT levels.
	* 1 DP for every 100 BRPs (round down).
	* DPs from other sources: see the Diplomatic Tables.
6. Allocate DPs
	* Each alliance faction may place up to one third of its DPs (round up) in any one target.
	* The Western Allies and European Axis may each place up to two DPs in USAT in 1939, and up to four DPs in 1940 and 1941.
	* The Western Allies and European Axis may each place up to two DPs in RGT in 1939, and up to four DPs in later years.
	* Russia may only place DPs in Bulgaria, Finland, Greece, Hungary, Rumania, Sweden, Turkey, the Ukraine and Yugoslavia.
	* DPs may be placed in intelligence research categories.
7. Allot RPs
	* Basic Allotments: Germany: 8; Japan, Britain, Russia: 6; France: 3; Italy: 2; US: 1 per every 10 USAT+USJT levels.
	* RPs for BRPs: one for every 50 BRPs (round down).
	* RPs from growth: one for every 25 BRP lost due to BRP growth (round down).
8. Allocate RPs.
	* No more than half (round up) of an alliance faction's RPs may be placed in a single research category.
	* Each alliance faction may only place 3 RPs in any given research or production project.
	* After having achieved 1 breakthrough in that category and if one country has 400 or more BRPs during the YSS, this limit rises to 4.
	* After having achieved 2 breakthroughs in that category and if one country has 500 or more BRPs during the YSS, this limit rises to 5, etc.
	* There are other restrictions for high technology projects, atomic research, date restrictions, and nationality restrictions.
9. U.S. Election (1945 YSS only).
