The number of LPCs with the contract arrangements described below, the revenues derived from such arrangements for the three and six months ended March 31, 2019, and the percentage of TVA’s total operating revenues for the three and six months ended March 31, 2019 represented by these revenues are summarized in the tables below:

TVA Local Power Company Contracts At March 31, 2019
Contract Arrangements(1)	Number of LPCs			Sales to LPCs in the Three Months Ended March 31, 2019 (in millions)				Percentage of Total Operating Revenues in the Three Months Ended March 31, 2019
20-year termination notice	3			$	34			1.2	%
15-year termination notice	11			127				4.6	%
12-year termination notice	1			6				0.2	%
10-year termination notice	52			862				31.3	%
6-year termination notice	1			13				0.5	%
5-year termination notice	86			1,472				53.5	%
Total	154			$	2,514			91.3	%

Note

(1) Ordinarily, the LPCs and TVA have the same termination notice period; however, in contracts with five of the LPCs with five-year termination notices, TVA has a 10-year termination notice (which becomes a five-year termination notice if TVA loses its discretionary wholesale rate-setting authority). Two of the LPCs have five-year termination notices or a shorter period if any act of Congress, court decision, or regulatory change requires or permits that election.
