OPINION
Plaintiffs Joseph Waldman, Sadie Sage and Martin Dachs charge that the Elec-trospace Corporation, its former accountant, and various former officers and directors violated the federal secur*283ities laws1 by engaging in a continuing fraudulent course of conduct which was designed to, and which did, deceive purchasers of Electrospace securities like themselves as to the financial condition and net worth of the corporation. Their specific allegations of fraud include, but are not limited to: (1) material overstatement of inventory and accounts receivable in the corporation’s 1971 and 1972 audited financial statements, (2) material overstatement of income and revenues in the corporation’s interim financial statements for 1971, 1972 and 1973, and (3) failure to disclose in 1973 current IRS proposals for upwards adjustment of corporate income tax assessments. This course of conduct allegedly resulted in an inflation of the market price of Electrospace securities.
Plaintiffs have moved the court for consolidation of this action pursuant to Rule 42(a), Fed.R.Civ.P., with two other 10b-5 suits 2 subsequently filed by other purchasers of Electrospace securities. The subsequent cases name as defendants four of the defendants named in Waldman. Plaintiffs in these actions have joined in the Waldman motion for consolidation. In addition, all three groups of plaintiffs have moved for class action certification of the consolidated cases pursuant to Rule 23, Fed. R.Civ.P. For the reasons discussed below, the motion for consolidation is granted. The motion for class action determination is denied without prejudice to renewal should plaintiffs prove able to remedy the present deficiencies in their class action allegations.
CONSOLIDATION
Rule 42(a) of the Federal Rules of Civil Procedure provides:
When actions involving a common question of law or fact are pending before the court, it may order all the actions consolidated; and it may make such orders concerning proceedings therein as may tend to avoid unnecessary costs or delay.
For reasons detailed below in discussion of plaintiffs’ Rule 23 motion, the court finds that common questions of law and fact exist in the three actions sought to be consolidated. This conclusion by itself, however, does not mandate consolidation.
It is well recognized that consolidation of stockholders’ suits often benefits both the court and the parties by expediting pretrial proceedings, avoiding duplication of discovery and minimizing costs. See Feldman v. Hanley, 49 F.R.D. 48, 50 (S.D.N.Y. 1969). It is also true, however, that consolidation may in some instances so prejudice the rights of a defendant that even in the exercise of its sound discretion the court cannot permit it, Garber v. Randell, 477 F.2d 711 (2d Cir. 1973). In this ease four defendants who are named in the Waldman action only allege that consolidation would seriously prejudice them. The men, Harvey Cohen, Morton Lowenbraun, Martin L. Rein, and Herbert L. Wolf, are all former directors of the corporation.3 They assert that unlike the de*284fendants named in all three complaints, they are actors on the periphery of the activities alleged to constitute a fraudulent course of conduct. To consolidate the case against them with those against the lead actors, they assert, is to make them defendants in cases in which they have not been charged, to unreasonably complicate their trial, and to subject them to expenditure of “unnecessary counsel fees” for additional discovery.
The court finds none of these objections compelling. Consolidation does not result in merger, and therefore by itself4 does not, as defendants assert, make them parties to all three actions. Abrams v. Occidental Petroleum Corp., 44 F.R.D. 543, 547 (S.D.N.Y. 1968). Although it is true that much of the proof presented in these actions will relate to technical accounting principles, the charges and therefore the proof of deviation from generally accepted accounting practices in each case are the same; consolidation therefore does not in this instance compound the technicality or complexity of issues to be presented to a jury. The fact that the Wald-man plaintiffs have raised a claim against these defendants which plaintiffs in the other two actions have not does not militate against a consolidated trial.5 Enough common and related issues exist with respect to all claims to indicate that it would needlessly waste both time and manpower to require separate trials. Cf. Gerber Products Co. v. Beech-Nut Life Savers, Inc., 25 F.R. Serv. 42a.l (S.D.N.Y.1958). It is this court’s opinion that rather than requiring expenditure of “unnecessary counsel fees,” consolidation will result in a savings of expense for both the parties and the court.
CLASS ACTION DETERMINATION
Plaintiffs seek to represent a class of persons who purchased Electrospace common stock or, Electrospace 5%% convertible subordinated debentures due October 1, 1983, during the period of January 1, 1972 through April 26, 1974,6 *285and who either retained their securities or sold them at a loss.7 To win class action certification under Rule 23, plaintiffs must demonstrate: (1) that the class is so numerous that joinder of all members is impracticable, (2) that there are questions of law or fact common to the class, (3) that their claims are typical of those of the class, (4) that they will fairly and adequately represent the interests of the class, (5) that common questions of law or fact predominate over individual questions and (6) that a class action is superior to other available methods of adjudication.8 The court will consider each requirement separately.
Numerosity: Plaintiffs allege that between December 31, 1971 and December 31, 1972 the number of shares of Electrospace common stock outstanding increased 'by over 790,000. They further assert that the number of debenture holders of record decreased by 150 during the same time period, and therefore conclude that “for purposes of this motion it should be assumed that the number of shareholders and debenture holders that are included in the class is in the thousands.”9 It takes more, however, than plaintiffs’ ipse dix-it to make a class. Professional Adjusting Systems v. General Adjustment Bureau, 64 F.R.D. 35 (S.D.N.Y.1974). Their terse argument to the contrary, a decrease in the number of debenture holders of record supports no presumption that anyone new purchased debentures, much less that so many purchased as to make joinder impractical.
Nor is plaintiffs’ assertion as to increase in shares of stock probative of . numerosity. Defendants Lowenbraun and Rein point out that approximately 770,000 shares of the 790,000 share increase were due to a three for two stock split distributed to shareholders on March 15, 1972. The “evidence” plaintiffs present of class size and impractieality of joinder, therefore, amounts to no more than mere speculation. In such circumstances, the court has no choice but to deny class action status; “it is fundamental that those seeking to maintain an action as a class action must make a positive showing that it would be impractical to deny the prayer.” Demarco v. Edens, 390 F.2d 836, 845 (2d Cir. 1968). See also Burstein v. Slote, 12 F.R.Serv.2d 23c.l, case 2 (S.D.N.Y.1968).
Common Questions of Law or Fact: Where it is alleged that a series of statements containing interrelated and cumulative data were released to the public, the court is presented with a course of conduct raising questions *286common to all who purchased during the period of dissemination. Green, v. Wolf Corp., 406 F.2d 291, 299-300 (2d Cir. 1968), cert. denied, Troster, Singer & Co. v. Green, 395 U.S. 977, 89 S.Ct. 2131, 23 L.Ed.2d 766 (1969); Aboudi v. Daroff, 65 F.R.D. 388, 390-91 (S.D. N.Y.1974); Fischer v. Kletz, 41 F.R.D. 377, 381 (S.D.N.Y.1966). The resolution in one litigation of such common questions, relating to the existence, character and materiality of defendants’ alleged misrepresentations is both a logical and appropriate way in which to proceed. In re Caesar’s Palace Securities Litigation, 360 F.Supp. 366, 398 (S.D.N.Y.1973); Berland v. Mack, 48 F.R.D. 121, 127 (S.D.N.Y.1969). Common questions in this case include, but are not limited to: (1) whether the 1971 and 1972 Electrospace financial statements overstated net income and assets, (2) whether the overstatements, if they existed, were material, (3) whether the defendants failed to disclose contingent income tax assessments, (4) whether this failure, if it existed, violates the federal securities laws and (5) whether all of the above constitute fraudulent manipulation of the market price of Electrospace securities.
Typicality: At this stage of the litigation the court perceives no evidence which would indicate that plaintiffs’ claims are atypical or antagonistic to the claims of those they seek to represent. Defendants suggest that these claims cannot be typical because there has been no showing of the identity or numerosity of class members and therefore no showing that their purchase time and price are substantially similar to plaintiffs’. As the Honorable Lawrence Pierce noted in Aboudi v. Daroff, supra, this argument contains a fundamental flaw:
The course of action of the stock is not equivalent to the course of action of the defendants. . . . Plaintiff’s claim is that the reports and statements of defendants throughout the entire period were false and misleading, that these reports and statements were related to one another, and that as a result of these related actions, the market price was inflated above its true value at every point throughout the period, regardless of what that price happened to be or in which direction it happened to be moving at any particular time.
65 F.R.D. at 391.10 If the court should later find that class action certification is appropriate and that distinctions must be drawn between those who purchased the stock at different times or prices, or between those who purchased debentures and stockholders,11 it can avail itself of the flexibility inherent in Rule 23. Green v. Wolf, 406 F.2d at 291. See Rule 23(c), (d).
Fair and Adequate Representation: Plaintiffs appear to have a strong personal stake in the outcome of this litigation which is in no way antagonistic to the interests of purported class members. Their attorneys, furthermore, are qualified and experienced in class action litigation. The essential ingredients of fair and adequate representation are therefore present. Defendants argue that the financial ability of the *287representative parties to pay for notice to the class and other costs of litigation is also relevant, and ask that any decision on class action certification be delayed pending discovery into plaintiffs’ financial resources. This court recently sustained such an argument where the potential class clearly numbered in the hundreds of thousands, and the cost of notice alone far exceeded the possible recoveries of named plaintiffs. See Dennis, et al. v. Saks & Co., et al., 74 Civ. 4419, Memorandum Decision and Order, July 10, 1975 (S.D.N.Y.). The appropriate discovery, however, where called for, is not discovery by defendants of plaintiffs’ financial soundness, but plaintiffs’ submission to the court in camera of affidavits on this issue. Defendants’ motions to compel appearances at depositions and answers to interrogatories, therefore, are denied. If and when plaintiffs succeed in demonstrating the requisite numerosity for a class action determination, the court will consider requiring submission of in camera affidavits.
Predominance of Common Questions and Superiority of a Class Action: Decision on these last two factors, as well as on the definition of a class must perforce await a showing as to identity and numerosity of potential class members.
To summarize the court’s decision, then, plaintiffs’ motion for consolidation is granted, and counsel for plaintiffs in Waldman, et al. v. Electrospace, et al. is appointed lead counsel. Plaintiffs’ motion for class action determination is denied without prejudice to renew. Defendants’ motions .to compel discovery on the issue of plaintiffs’ financial resources are denied. Defendants’ motions to the extent they seek a stay of class action determination pending discovery are dismissed as moot.
So ordered.
