Howard Vesey was killed on October 3, 1969 in the crash of Metro Commuter Airlines Flight 201 during an attempted landing at Denver’s Stapleton Airport. Following the fatal crash, Jeanne T. Vesey filed federal tort claims on her own behalf; as administratrix of Howard Vesey’s estate; and as guardian for her minor son, Wade Tillery Vesey. She also filed claims in state court against Metro Airlines but the Metro claims were settled upon payment of $95,000.

A trial on liability only was completed in 1973. In that phase of the litigation the claims of the pilot, the co-pilot and the passengers in Metro 201 were joined in a multidistrict case against the United States and Beechcraft Corporation. The United States denied negligence and by way of a third party complaint against Metro Airlines and its officers claimed the proximate cause of the crash was negligent operation of the aircraft. However, the trial judge in his decision found the United States liable for negligence on the part of its air traffic controllers and dismissed the third party complaint finding no negligence on Metro’s part.

The damage claims of Jeanne Vesey came on for trial before the United States District Court for the Central District of California in 1974. The trial judge determined the average annual income of the deceased, prior to death, was approximately $97,000 but concluded that his “annual future earning capacity” would have been no more than $14,030. The judge ruled that Jeanne Vesey was not entitled in her own right to recover, but as administratrix was entitled to funeral expenses of $6,064. Wade Tillery Vesey, decedent’s minor son, was awarded $36,000 compensation for the loss of his father’s comfort and society and an additional $15,608 for his apportioned part of the projected future earnings of the deceased.

Jeanne Vesey has appealed claiming several errors in the award of damages and we have jurisdiction. 28 U.S.C. § 1291 .

The administratrix first contends the trial judge erroneously computed the earning capacity of the deceased. Indeed, relying upon Smith v. Circle Inn, 73 Cal. App.3d 86, 94 ; 140 Cal.Rptr. 566, 571 (1971), she suggests that the award of damages is so inadequate as to demand reversal. Whatever may be the rule in California, we are required to apply the “clearly erroneous” federal standard:

Miller v. United States, 587 F.2d 991, 994 (9th Cir. 1978); Felder v. United States, 543 F.2d 657, 663 (9th Cir. 1976).

In this case the trial judge substantially rejected the testimony of Brian J. Gaggs offered by the administratrix. We are satisfied the trial judge instead relied upon documentary evidence contained in the decedent’s records and tax returns. The documentary evidence reveals that for several years prior to his death the decedent was able to minimize his personal income, apparently for tax purposes. Decedent owned substantial investments including the Hope Ranch Realty Investment Company. While Hope Ranch earned substantial proceeds, the decedent was paid only a modest annual salary. The administratrix argues that any calculation of the decedent’s earning capacity should include a share of retained earnings from Hope Ranch.

In those instances when a share of retained earnings is recognized as appropriate for computation of future earnings, plaintiff must make a substantial showing that decedent’s own services, efforts and initiative, rather than capital invested or labor of others, was the predominant factor producing the profits of the business. The trial judge was not clearly erroneous in finding that:

Testimony at trial revealed that the retained proceeds of Hope Ranch derived, in large part, from the sale of residential property. Moreover, it appears that the proceeds of the company remained approximately the same following decedent’s death. In short, the retained profits were not the result of the decedent’s skill and efforts but largely came about by appreciation of the property. We conclude that the findings of the trial judge were not clearly erroneous in this regard.

The administratrix also contends that a management fee based on a percentage of annual purchases and sales of stock from decedent’s portfolio ought to be considered as a factor in future earnings even though decedent charged no such fee prior to his death. To support this position, the administratrix offered the testimony of an accountant and testimony of decedent’s part-time business partner, John Vesey. Their personal knowledge of the amount of time spent by decedent in management of his stock portfolio appears doubtful from the record. Additionally, the testimony suggests that decedent was not the exclusive manager of his stock portfolio. While the accountant testified as to total purchases and sales from the stock portfolio for the period 1960-1969, the record reflects little evidence as to the average value of the portfolio for those years. The trial court found in this connection:

We agree with the trial court that a fee based on average value of the portfolio rather than a percentage based on stock transactions is more appropriate. The administratrix argues that an award of 1% on the $25,156, which the court determined to be the approximate value of the stock portfolio was erroneous for several reasons. Initially, it is suggested that the $25,156 value does not appear in the record. We find the underlying evidence on page 3 of Plaintiff’s Exhibit 4. The exhibit reveals the appraised value of decedent’s stock portfolio as of June 12,1970. The $25,156 is arrived at by deducting from the total appraised value of the stock the appraised value of decedent’s 40,000 shares of Hope Ranch Realty Investment Company. As the trial judge had included in his computations of the decedent’s future earning capacity his annual salary from Hope Ranch, he deducted the value of Hope Ranch stock from the total stock in the portfolio. Thus he computed the management fee on the value of the remaining shares of stock in the portfolio. This ruling appears to be based on a theory prohibiting double recovery and we believe it was correct. Since the appraisal of June 12, 1970 affords the only evidence upon which reliable information might be obtained as to the value of the stock portfolio, the computation based on $25,156 was proper.

The administratrix also attacks the management fee award on a theory that the trial court could have calculated a minimum portfolio value for each of the years in question and should have applied the 1% factor to the annual portfolio minimum. According to the administratrix, calculations using exhibit 21 could have been employed to obtain an annual minimum value of the stock portfolio beginning in 1960. From our review of the record, however, we believe there was insufficient data upon which the trial court could have reliably made such calculations. In any event, we conclude the methods selected by the trial judge to fix the appropriate value of the stock portfolio based upon the appraisal of the portfolio as of June 12 was not error.

Next, the administratrix contends that the trial court erroneously refused to accept an inflation factor to increase the damage award. According to the administratrix, the testimony of Professor Raymond G. Schultz fully justified an award for inflation during the years from the time of the crash through the remainder of decedent’s projected life span. Professor Schultz employed the actual rates of inflation for the period from the crash to trial on the damage issues. In calculating an inflation factor for the period from 1975 through 1977, he employed the projection of the President’s Council of Economic Advisors. For the remaining period of decedent’s life span, from 1977 onward, he arrived at a projected rate of 3% based on the annual inflation rate for the period 1960 to 1964. However, the trial judge rejected the testimony relating to an inflation factor:

In United States v. English, 521 F.2d 63 (9th Cir. 1975) this circuit recognized the need to consider the effect of inflation when awarding damages:

Id. at 75 . See also Sauers v. Alaska Barge, 600 F.2d 238, 245 (9th Cir. 1979); Maheu v. Hughes Tool Co., 569 F.2d 459 , 477 n.11 (9th Cir. 1977); Burlington Northern, Inc. v. Boxberger, 529 F.2d 284 (9th Cir. 1975).

The English court went on, however, to warn of the need for competent evidence in assessing the impact of inflation on such awards.

521 F.2d at 75-76 . Although Professor Schultz testified as to the general inflationary trends, this effect was never related to the components of decedent’s future earnings. In short, the administratrix offered evidence relevant to inflationary trends but failed to connect that evidence with any potential erosion of decedent’s future earning capacity. We conclude that the administratrix’s failure to link evidence of general inflationary trends to the specific components of decedent’s income requires that the judgment of the trial court be affirmed. As we have observed, the decedent was able to a substantial degree to manage his income as he chose. The holding of the trial judge was consistent with the personal financial policies of the decedent.

Finally, appellant contends the trial judge misapplied California law when he allowed the United States a setoff of $95,-000, the proceeds of the settlement obtained from Metro. During the damage phase of the trial, the United States brought forth testimony relating to the Metro settlement and the trial judge concluded:

The administratrix now urges that § 877 of the California Code should be held inapplicable to the Metro settlement for several reasons. She suggests that in the liability trial the district court explicitly found that Metro was not liable for the crash. Additionally, she maintains that the settlement for Metro was based on claims of fraud rather than on claims of negligence.

Both theories must be rejected. The provisions of § 877 of the California Code apply to any person who is an “alleged tortfeasor.” Stambaugh v. Superior Court, 62 Cal.App.3d 231, 235 ; 132 Cal.Rptr. 843, 845 (1976). According to the administratrix’s state court complaint, Metro and its pilots, agents, servants and employees so recklessly, negligently, carelessly and unlawfully maintained, operated and piloted the aircraft as to cause it to crash resulting in Howard Vesey’s death. Thus Metro’s subsequent exoneration of negligence in the liability trial is of no legal significance in the present case. Additionally, the fundamental purpose of § 877 of the California Code is to preclude a double recovery arising out of the same wrong. As explained in Carr v. Cove, 33 Cal.App.3d 851, 855 ; 109 Cal.Rptr. 499 , 451 (1973):

Since there was but a single wrong — the death of Howard Vesey — caused by the fatal crash, the partial satisfaction obtained from Metro must be applied to reduce the total damages. The administratrix’s contention, if adopted, would necessarily result in double recovery and therefore, cannot be accepted.

Evidence at trial was sufficient only to show that the release related to the claims of Jeanne Vesey in her own behalf. However, appellant’s reply brief incorporated a copy of the settlement in state court. According to that document, the settlement totaled $95,000, of which Jeanne Vesey received $65,322, the minor, Wade Tillery Vesey, received $23,750 and Howard Vesey’s adult daughter received $5,928.

The district court may wish to consider this evidence not previously before it. We, therefore, direct that a motion for a new trial on the terms of the settlement and its effect on the setoff may be entertained by the district court within 35 days after the issuance of the mandate.

The decision of the district court is otherwise affirmed.

. The claims were initially filed in state court where they were joined with a claim against Metro Airlines. After settlement of the claims against Metro, the case was removed to federal court. . The liability was extensively briefed after the 1973 trial and the United States District Court for the District of Colorado entered its holding nearly a year after trial. The liability holding is reported as DeWeese v. United States, 419 F.Supp. 147 (D.Colo.1974). The individual damage case was then tried. DeWeese v. United States, 419 F.Supp. 170 (D.Colo.1976). Both DeWeese I and DeWeese II were affirmed in DeWeese v. United States, 576 F.2d 802 (10th Cir. 1978). . 419 F.Supp. at 168-69. . California Code of Civil Procedure, Section 877 states: Where a release, dismissal with or without prejudice, or a covenant not to sue or not to enforce judgment is given in good faith before verdict or judgment to one or more of a number of tortfeasors claimed to be liable for the same tort— (a) It shall not discharge any other such tortfeasor from liability unless its terms so provide, but it shall reduce the claims against the others in the amount stipulated by the release, the dismissal or the covenant, or in the amount of the consideration paid for it whichever is the greater; and (b) It shall discharge the tortfeasor to whom it is given from all liability for any contribution to any tortfeasor. . The fraud claim is based upon Metro’s alleged concealment of its lack of assets. Plaintiffs contend that this concealment was fraudulent and that the decedent would never have flown Metro if he had known of its insolvency. A fair reading of the complaint suggests the claim of fraud is an afterthought as the allegations relate only to the crash as the proximate cause of the injury.
