concurring in the result.
When the owners of the Citizen and the Star embarked upon their joint venture in 1940, they did not believe that they were combining their commercial operations for all time. Rather, their contract provided that the venture would last for 25 years and that the relationship *141would terminate in 1965 if both parties agreed to go their separate ways. It was only in 1953 that the parties agreed they would not permit their contract to expire in 1965 but would continue their relationship for another quarter century beyond the original termination date.
Nevertheless, both the Department of Justice and my Brethren have decided that the crucial question in this case is whether the original 1940 transaction could be justified on “failing company” grounds. Yet regardless of one’s view of the 1940 transaction, the fact remains that if the parties had not renewed their agreement, full competition between the two newspapers would have been restored in 1965 and the Justice Department would never have begun the Sherman Act branch of this lawsuit. It would appear, then, that the decisive issue in this case is not the validity of the original 1940 transaction but the propriety of the decision taken in 1953 in which the term of the joint venture was extended by a quarter century beyond its original termination date.
In defense of the Court’s approach, one may argue that if the 1940 agreement had provided that the newspapers’ joint venture was to continue indefinitely, we would then have been required to decide this case on the basis of the situation prevailing at the time of the original transaction. In other words, if the agreement had been only slightly different it is arguable that we would have had no choice but to treat the transaction in the same way we would treat a total corporate merger. However this may be, I do not understand why the parties’ decision to retain the advantages of flexibility should not be decisive for our purposes. If businessmen believe, after considering all the relevant factors, that future events may deprive their existing arrangements of utility, there is no reason why the antitrust laws should not view the transaction in a similar way.
*142While the trial court did not analyze the case in the way which I have suggested, it made sufficient factual findings to permit an evaluation of the legality of the 1953 decision extending the joint venture’s term. The Court in effect found that in each year between 1940 and 1953, each newspaper operated at a profit. Moreover, in the decade preceding 1953, the joint venture’s total profits increased with each succeeding year. Given this pattern of increasing profitability, I would hold that the "failing company” doctrine could not reasonably permit the two newspapers to extend the term of the agreement in 1953 at a time when it was impossible to predict whether full competition could be renewed in 1965.
Nor can the newspapers appropriately invoke the “failing company” defense to justify another quarter century’s joint operation on the basis of the financial situation which actually existed in 1965. For the trial judge found that the joint venture’s profits had continued their upward spiral with each year, reaching $1,727,217 in 1964, and that both the newspapers are now “in sound financial condition.” 280 F. Supp. 978, 983. Moreover, in the quarter century since 1940, the number of households in the Tucson area has almost quadrupled, see Government’s Exhibit 55, App. 452, and total circulation of the Star and the Citizen has increased proportionately. See Government’s Exhibit 49, App. 448-450. While the District Court found it “impossible to predict” how well the two papers could compete without their present agreement, 280 F. Supp., at 993, I would hold that the joint venture’s profitability required the companies to make a conscientious effort to operate independently before they could properly contend that their operating agreement was a business necessity.
Consequently, although I join in the Court’s judgment in this case, I find it unnecessary to define the *143circumstances in which a declining newspaper may properly act to assure its future independence as a news medium by entering into a joint operating agreement similar to the one challenged here.
