Pеter Reilly and Donna Reilly, husband and wife, and their minor daughter, Heather, appellees before us, brought this medical malpractice action against the United States pursuant to the Federal Tort Claims Act (FTCA), 28 U.S.C. §§ 1346(b), 2671
et seq.
Following a bench trial, the United States District Court for the District of Rhode Island awarded plaintiffs $11,037,-964 in damages and entered a judgment in that amount.
Reilly v. United States,
Appellant recites an alphabet of error: it claims, among other things, that the court below erred in—
Appointing a technical advisor;
B rushing aside a state collateral source statute;
Calculating lost earning capacity;
Declining to order staggered payments in lieu of a lumpsum award (or in the alternative, refusing to consider the cost of a periodic-payment annuity in determining damages);
Exceeding the amount of plaintiffs’ administrative claim without just cause; and
Fashioning an award which allowed du-plicative recovery.
Given the range and reach of appellant’s contentions, this futhark should be read as more limning than limitary. Yet the appeal is a mixed bag. The government has raised some close questions which deserve careful attention and analysis; we address those in the alphabetical order listed above, except that we merge the third and sixth assignments of error. On the other hand, appellant has also attempted to capitalize on avowals which are patently meritless, or procedurally defaulted, or both; those need not be mentioned specifically, but are rejected out of hand. When everything is said and done, we find that the judgment is *153 consonant with the letter of the law in all particulars save one.
I. BACKGROUND
Liability is conceded, as is the nature and extent of Heather Reilly’s injuries.
See Reilly I,
A. What Transpired. On December II, 1984, Peter Reilly was on active duty with the Navy. On that date, a gravid Donna Reilly was admitted to Newport Naval Hospital. After some six hours in labor, the electronic monitor indicated a dramatic deceleration in fetal heart rate. The district court found, supportably, that this development should have signalled the obstetrician to perform a caesarean section immediately because the baby was in danger of asphyxiation. Id. at 979. The physician instead removed the monitor and insisted on undertaking a vaginal delivery, thereby delaying the birth. When the delivery was eventually performed, it required the application of a vacuum/suction instrument to the baby’s head. The departure from prudent professional standards was palpable.
As a result of the doctor’s manifest negligence, Heather Reilly was born with severe, apparently irremediable, brain damage. The district court determined, sadly but accurately, that she was left “a helpless individual, ‘significantly delayed developmentally’ and unable to see; she will never be able to walk, talk, feed or take care of herself in any way.” Id.
B. Travel of the Case. Heather’s parents filed an administrative claim with the Navy on May 7, 1985 in the amount of $10,000,000. When the matter was not definitively resolved within six months next following, suit was brought under the FTCA. 1 The administrative claim was never amended.
Plaintiffs’ complaint sought damages for Heather’s grievous injuries and losses consequent thereto (including future-care expenses and deprivation of earning capacity). Mr. & Mrs. Reilly also sued for emotional distress and loss of love, society, and affection.
See Reilly I,
During the interval between the trial and the resumed hearings, the district judge attempted to enlist an economist to assist him in respect to certain technical aspects pertinent to the calculation of a damage award.
Reilly II,
The AUSA immediately requested a chambers conference. The session was held on April 10, 1987. The district judge recounted his conversations with the economists and made no bones about his intent *154 to hire one as a technical advisor. He informed all counsel that he had already contacted the Administrative Office of the United States Courts (AO) to this end, and that he was awaiting approval from the Chief Judge of the First Circuit. 2 The government voiced no contemporaneous objection to the procedure, did not ask the name of the economist whom the court intended to retain, did not ask that either the court’s instructions to the expert or the expert’s advice be reduced to writing, and did not request an opportunity to question him.
To make a tedious tale tolerably terse, the approvals were forthcoming,
see Reilly II,
The government moved for a new trial, amending its motion in December 1987 to add Dr. Mead’s service as a further basis for relief. The motion was denied by the district court in an erudite opinion concerned exclusively with the court’s engagement of a technical advisor.
Reilly II,
It is against this backdrop that we proceed to ponder the orthography of appellant’s alphabet of error.
II. APPOINTING A TECHNICAL AD-VISOR
The United States concedes that a district court has inherent authority to appoint an expert as a technical advisor. 4 See, e.g., Appellant’s Brief at 22-23 n. 17; Reply Brief at 1. It maintains, notwithstanding, that (1) such power is strictly circumscribed *155 by Fed.R.Evid. 706(a), 5 a rule whose protocol the district court saw no need to obey; (2) the court abused its discretion in appointing an advisor at all in this case; (3) the court’s appointee far exceeded the limited role of a technical advisor; and (4) the absence of meaningful procedural safeguards rendered utilization of the advisor fundamentally unfair. We examine these points seriatim.
A. Rule 706.
Throughout its text, Fed.R.Evid. 706 refers not to “experts” generally, but to a more exclusive class: “expert witnesses.” Because the plain language of a Civil Rule is the most reliable indicator of its meaning, we are constrained to conclude that the grasp of Rule 706 is confined to court-appointed expert witnesses; the rule does not embrace expert advisors or consultants.
Accord Reed v. Cleveland Bd. of Educ.,
This conclusion is buttressed by the text of the advisory committee notes (Notes) accompanying Rule 706. As we read them, the Notes seem geared exclusively to expert witnesses as opposed to technical ad-visors. For example, they cite “expert witness” cases such as
Danville Tobacco Ass’n v. Bryant-Buckner Assocs., Inc.,
We acknowledge that the question is not free from all doubt. The government, in support of its argument to the contrary, relies on a statement by two respected commentators that “the provisions of ... Rule 706 operate as restrictions on the judge’s common law power to appoint experts.” 3 J. Weinstein & M. Berger,
Wein-stein’s Evidence
11706[02] at 706-15 (1988). Yet this statement, we suggest, can — and should — be interpreted to encompass only the appointment of expert witnesses. Indeed, such an interpretation would seem to be contextually indicated, as the very next sentence in the cited text predicts that: “The dissent rather than the majority opinion in a case such as
Scott v. Spanjer Bros., Inc.
would now prevail.”
Id.
at 706-15 to -16. In
Scott,
the dissent argued that the lower court erred in appointing an expert witness without giving reasonable notice to the parties.
Scott,
The substance as well as the language of Rule 706 comports with this interpretation. The rule establishes a procedural framework for nomination and selection of an expert witness and for the proper performance of his role after an appointment is accepted
{e.g.,
advising the parties of his findings, submitting to depositions, being called to testify, being cross-examined). By and large, these modalities — though critically important in the realm customarily occupied by an expert witness — have marginal, if any, relevance to the functioning of technical advisors. Since an advisor, by definition, is called upon to make no findings and to supply no evidence,
see infra
Part 11(C), provisions for depositions, cross-questioning, and the like are inapposite.
See Hemstreet v. Burroughs Corp.,
The finishing touch is in the caselaw. The United States, despite herculean efforts, has adverted to no reported cases binding the engagement of technical advis-ors with the strands of Rule 706. Without exception, the cases cited by the government for the proposition that the rule “sets out the controlling legal standard pertaining to the court’s appointment of a neutral expert,” Appellant’s Brief at 18, are “expert witness” cases, not “technical advisor” cases.
See, e.g., Students of California School for the Blind v. Honig,
We conclude, therefore, that Rule 706, while intended to circumscribe a court’s right to designate expert witnesses, was not intended to subsume the judiciary’s inherent power to appoint technical advisors. The Civil Rules, after all, wеre never meant to become the sole repository of all of a federal court’s authority.
See HMG Property Investors, Inc. v. Parque Indus. Rio Canas, Inc.,
B. Abuse of Discretion.
The government’s immediate fallback position is that, even if literal compliance with Rule 706 was not essential, the district court nevertheless abused its discretion in appointing a technical advisor at all. We concur wholeheartedly that such appointments should be the exception and not the rule, and should be reserved for truly extraordinary cases where the introduction of outside skills and expertise, not possessed by the judge, will hasten the just adjudication of a dispute without dislodging the delicate balance of the juristic role.
Cf. La Buy v. Howes Leather Co.,
We wish to emphasize our strongly-held view that the appointment of a technical advisor must arise out of some cognizable judicial need for specialized skills. Appro *157 priate instances, we suspect, will be hen’s-teeth rare. The modality is, if not a last, a near-to-last resort, to be engaged only where the trial court is faced with problems of unusual difficulty, sophistication, and complexity, involving something well beyond the regular questions of fact and law with which judges must routinely grapple. Although a technical advisor can be valuable in an appropriate case, the judge must not be eager to lighten his load without the best of cause.
Despite the fact that the integument as we have shaped it is a narrow one, see supra, we believe that this litigatiоn slips fittingly within it. The ease involved esotérica: complex economic theories, convoluted by their nature, fraught with puzzlement in their application, leading to a surpassingly difficult computation of damages. Future-care expenditures and lost earnings had to be projected over a 70-year period — and for an infant with no proven financial track record. Plaintiffs’ experts differed among themselves on some points. The stakes were demonstrably high. The government was of small help. Its submission on damages, amounting to little more than a lick and a promise, can best be characterized as feeble. The one-sidedness of the evidence itself lent encouragement to the use of a technical advisor to help the court understand the theories which were bruited about. All in all, the litigation was so far outside the mainstream that the judge, in our estimation, had good reason to energize his inherent power to bring a technical advisor on board. Cf. Manual for Complex Litigation, Second (MCL 2d) § 21.54 (1985) (court may consider appointing confidential advisor in “complex litigation” and “when complicated issues are involved”). Mindful of the trier’s discretion in this regard, the charge of abuse simply will not wash.
C. The Technical Advisor’s Role.
Our decision that this was a seemly case for nominating a technical advisor and that the district court was not bound to comply with the requirements of Rule 706 in making the appointment does not end this phase of our inquiry. The government argues that, whatever may be said of the need for the appointment or its mechanics, the district court permitted Dr. Mead to roam far beyond the precincts to which a technical advisor must properly be confined. In the end, the government hints, the judge abdicated the factfinding function in favor of Dr. Mead, relying on him to resolve the merits. We find that the district court’s use of its expert in this case was limited to appropriate technical assistance, and therefore reject the government’s plea.
We start with a restatement of the principle derived from a watershed case anent technical advisors.
7
In
Ex parte Peterson,
In this case, it does not appear that the district judge stepped over the line. His description of how he used the advisor is illuminating:
Untrained in the nature and nuances of economic functions, unable to scrutinize the relevance of alleged independent variables or objections thereto, uncertain of the grounds and bounds of valid economic inference, this court recognized its need of a guide to lead it through the maze of economic theory and fact. To this end, [I] decided to adopt the somewhat unusual but not unprecedented procedure of procuring neutral technical advice.
Reilly II,
Nor can it validly be argued that the court gave mere lip service to the limitations which it imposed on the advisor’s role. The opinion on the merits indicates plainly that the judge neither relied on evidence supplied by Dr. Mead in reaching conclusions in the case nor deferred unduly to the expert in finding the facts. It takes scant analytic insight to see that the court below rejected the calculations of lost earning capacity proffered by the government’s expert not because of any new facts or theories introduced by the technical advisor, but because the witness’s testimony rested on an inadequate factual and legal basis.
See, e.g., Reilly I,
Appellant seeks to convince us that the reverse is true by pointing to the judge’s statement that he sought an expert to assist him in “reconciling the testimony of at least two outstanding experts who take opposite positions.” J.A. 273. This remark, however, proves little. It is, we think, a fair description of what a technical advisor might, with the utmost propriety, undertake. We do not read into it the sinister connotations urged by the government.
A second contention hawked by appellant is more troublesome. The government urges that because Dr. Mead received no written instructions and submitted no written report, it is unclear to what extent the district court may have allowed the boundaries to be overrun. We agree that it would have been better practice to document the interchange between jurist and advisor in some more readily retrievable fashion. Yet we perceive no fatal flaw. In a variety of contexts, we have relied on a judge’s plausible explanation of his orders, findings, and the like.
See, e.g., United States v. Metropolitan Dist. Comm’n,
847
*159
F.2d 12, 14 (1st Cir.1988);
Lefkowitz v. Fair,
Appellant’s complaint that it was deprived of any opportunity to cross-examine Dr. Mead appears asthenic. If, as the district court stated, the advisor was not an evidentiary source, there was neither a right to cross-question him as to the economics of the situation nor a purpose in doing so. And, to the extent that it might have profited the government to grill Dr. Mead about his role in the case, the short and simple response is that, after being informed at the April 10 chambers conference that the district court intended to hire a technical advisor, the prosecutors did not ask for written specification of the advis- or’s anticipated role or attempt to reserve a right of inquiry. Even after the verdict was rendered and an objection belatedly interposed to use of the advisor, the government did not move for leave to question him. Having failеd to raise that point below, the United States cannot raise it for the first time on appeal.
See Aoude v. Mobil Oil Corp.,
In sum, we find the record to be consistent with the district court’s announced employment of Dr. Mead as a technical advis- or. There is, moreover, simply no reasoned basis on which we can conclude that, once he was engaged, the advisor’s performance of his functions strayed beyond the proper ambit of his role. The government’s insistence to the contrary is comprised of little more than self-serving speculation and self-interested surmise.
D. Procedural Safeguards.
Appellant has one remaining shot in its sling. It protests vigorously that, even where a technical advisor may appropriately be engaged by a trial judge outside the realm of Rule 706, fundamental fairness requires that the appointment be hedged about with a panoply of procedural safeguards. Among other things, appellant urges that the district court should have given advance notice to the parties of the expert’s identity and how he was to be used; that written instructions should have been prepared regarding the expert’s duties; and that Dr. Mead should have been required to file a written report. We are quick to acknowledge that these suggestions have some merit.
We think it advisable in future cases that the parties be notified of the expert’s identity before the court makes the appointment, and be given an opportunity to object on grounds suсh as bias or inexperience.
Cf. Hemstreet,
Our belief in the value of such prophylactic measures, however, does not avail the government here. On April 10, the district court advised the parties that it had received permission from the paymasters in Washington to employ a technical advisor and that it had staged preliminary discussions with the intended appointee. The government did not inquire as to the expert’s identity or express any objection to the court’s use of an (unknown) expert; indeed, the United States Attorney, himself in attendance at the conference, appeared affirmatively to agree.
9
Nor did the government request that any safeguards be set in place. The record makes manifest that appellant sat back and knowingly acquiesced in the court’s unconditional hiring of an unidentified technical advisor. This was, we think, a waiver.
See Johnson,
Not only is there waiver here, but it is aggravated by an element of sandbagging. The government, knowing of the court’s plan to consult with a technical advisor, waited to see which way the wind blew. Only when the case turned out disastrously from the government’s viewpoint did appellant decide to voice its litany of concerns about the circumstances of the appointment. The record shows no valid reason why the United States, on April 10 or within a reasonable time thereafter, could not have objected to the hiring of any expert, demanded the name of the court’s candidate, or requested layer upon layer of special swaddling. Certainly, the government has offered us no persuasive reason to explain — let alone excuse — its lassitude. In our view, when a trial judge announces a proposed course of action which litigants believe to be erroneous, the parties detrimentally affected must act expeditiously to call the error to the judge’s attention or to cure the defect, not lurk in the bushes waiting to ask for another trial when their litigatory milk curdles.
See Pearson v. Fair,
We have weighed the contention, advanced in appellant’s reply brief, that it was informed only of the district court’s intention to hire a technical advisor. It asserts that it was never informed on April 10, or soon thereafter, that the court had in fact hired such a person. Therefore, the newfound thesis runs, the only real opportunity appellant had to object came after the decision eventuated in Reilly I. We find this logomachy to be entirely disingenuous. The district court’s statement of intent was more than sufficient to put the government on notice. Being on notice and doing nothing, it strikes us as not unfair that appellant should suffer the consequences.
Appellant’s last gasp on the point invokes the rubric of plain error. Concededly, we have the power to overlook many waivers or procedural defaults in cases where a gross miscarriage of justice would otherwise prevail or where the integrity of the judicial process is seriously threatened. This is not such an instance. The district judge has satisfactorily explained the reasons why he sought to engage a technical advisor, and they are proper reasons. There is no suggestion of bias or any other disqualifying characteristic on the expert’s part. And the judge’s account of the manner in which the advisor’s services were employed comports with the appropriate dimensions of the role and matches what can fairly be deduced from the record. There is no sign that justice was thwarted.
We need beat this drum no more. “Courts, like the Deity, are most frequently moved to help those who help themselves.”
Paterson-Leitch Co. v. Massachusetts Mun. Wholesale Elec. Co.,
III. THE COLLATERAL SOURCE CONUNDRUM
The FTCA requires resort to state substantive law, that is, “the law of the place where the [tortious] act or omission occurred.” 28 U.S.C. § 1346(b). This statutory directive has consistently been interpreted to require that damages in an FTCA suit — with a few exceptions not germane at this point — must be assessed in conformity with state law.
See, e.g., Flannery v. United States,
At common law, Rhode Island jurisprudence took a fairly conventional view of collateral sources in tort cases. The rule was — and remains—
that, absent a statutory provision to the contrary, the amount of recovery from one responsible for another person’s injury will not be reduced by the amount received from a collateral source by the plaintiff....
Soucy v. Martin,
The government contends that such a statutory exception is applicable in medical malpractice cases, including this one. The statute in question, now codified as R.I. Gen.Laws § 9-19-34.1, was amended slightly in 1986. Before then, the statute was codified as R.I.Gen.Laws § 9-19-34. Because the pre-1986 version applies to this case, we refer exclusively to it, leaving the amendment and recodification to one side. As written, the Rhode Island law provided in pertinent part:
[I]n an action for personal injury against a licensed physician, hospital, clinic, health maintenance organization or pro *162 fessional service corporation ... based upon professional negligence, [the defendant] may introduce evidence of any amount payable as a benefit to the plaintiff as a result of the personal injury pursuant to the United States social security act, any state or federal income disability or workers’ compensation act, any health, sickness or income-disability insurance, accident insurance that provides health benefits or income-disability coverage, and any contract or agreement of any group, organization, partnership, or corporation to provide, pay for, or reimburse the cost of medical, hospital, dental, or other health care services.
R.I.Gen.Laws § 9-19-34. The statute further stipulated that a plaintiff may introduce evidence of amounts contributed to secure such benefits in mitigation of the offset. See id.
The government seeks to employ § 9-19-34 to reduce the award against it by the amounts which would be paid for Heather’s care from three federal or partly-federal programs: the Civilian Health and Medical Program of the Uniformed Services (CHAMPUS),
see
10 U.S.C. §§ 1079, 1086, Medicaid, and the Education of All Handicapped Children Act (EAHCA), 20 U.S.C. § 1411
et seq.
The district court rejected this argument on dual grounds. First, it concluded that because the United States was not an enumerated entity under the state law, and was not one of the class of defendants (health care providers who purchase malpractice insurance) which § 9-19-34 was designed to assist, the statute had no application in this case.
Reilly I,
A. Scope of § 9-19-34.
The district court erred in concluding that § 9-19-34 was unavailable to the federal defendant in this case. The FTCA, not the letter of the Rhode Island statute, is the focal point of this inquiry and is determinative of the question. The intent of the Rhode Island General Assembly is, in a very real sense, irrelevant to the extent of the federal government’s liability in an FTCA suit. Local law “informs how a private party would be treated; it does not tell us, indeed it cannot, the extent to which the federal government has waived its sovereign immunity.”
Lucas v. United States,
The FTCA provides that “[t]he United States shall be liable ... in the same manner and to the same extent as a private individual under like circumstances.” 28 U.S.C. § 2674. Because a provider of medical services in the private sector would in “like circumstances” be eligible for a reduction of damages based on payments by collateral sources,
see
§ 9-19-34, the United States — which in this context can only be liable “to the same extent” as the private health-care provider — must be entitled to exactly the same largesse.
Accord Scheib v. Florida Sanitarium and Benevolent Ass’n,
We conclude that where Rhode Island law is to be applied in a medical malpractice case brought under the FTCA, the federal sovereign may avail itself of R.I. Gen.Laws § 9-19-34 to the same extent as could a hospital or other similarly-situated health-care provider in kindred circumstances. In a case like this, therefore, defendant was enfeoffed to introduce evidence of benefits received by the plaintiffs from collateral sources on account of the injuries and damages at issue, so long as those benefits fell categorically within the *163 genre of benefits contemplated by the state statute.
B. Entitlement to Offset.
Although § 9-19-34 applies in this case, nothing turns on it. We agree with the district court that the government “utterly failed” to meet its burden under the law.
Reilly I,
The state statute requires defendants who are desirous of spreading its soothing unguent to “introduce evidence of any
amount
payable as a benefit to the plaintiff.” R.I.Gen.Laws § 9-19-34 (emphasis supplied). In this case, appellant elicited only general allusions to plaintiffs’ possible eligibility to receive benefits. The district court found that the government “failed to develop any meaningful evidence as to the extent of the Reillys’ eligibility for CHAM-PUS payments or for aid under the [EAH-CA],”
Reilly I,
We have canvassed the record with painstaking care and decide, without serious question, that this finding was not clearly erroneous.
10
The situation, we think, is straightforward: the statute required evidence of the “amount[s] payable” as collateral benefits; defendant had the burden of proving the amounts; it introduced no real evidence to meet this burden. The district court could not be expected to reduce the award without (i) knowing the amount by which the government contended that damages should be reduced, and (ii) being afforded some proof of that sum.
Cf. Siverson v. United States,
IY. LOST EARNING CAPACITY
The district court awarded Heather Reilly $1,104,641 for lost earning capacity.
Reilly I,
A. Duplication.
Appellant’s assertion that the award for lost earnings replicates the award for future-care expenses, requiring the government to pay for Heather’s living expenses twice, is an innovative one. At the outset,
*164
appellant concedes the general proposition that Rhode Island law allows an injured party to recover for both prospective loss of earning capacity and future health-care expenses.
See, e.g., Caron v. United States,
Appellant’s asseveration stems from the decision of a divided panel in
Flannery v. United States,
In the usual case, a living plaintiff must pay his own living expenses, though an award for lost earnings may be the source of his funds. In [the case of a permanently comatose plaintiff], however, the plaintiff will be required to pay nothing, for the award of future medical expenses includes all of the personal expense that the plaintiff will incur. Indeed, the testimony was that, in the future, he will need little skilled medical care. His personal expenses will be to provide himself with housing, food, and nursing and custodial care of the kind provided in a nursing home. That is the expense covered by the award for future medical expense. The label should not be permitted to mislead us, for, in truth, the judgment requires the United States to pay the plaintiff’s personal living expenses twice. Thus, the award for lost earnings, as finally determined, should be reduced by the amount of the award for future medical expenses.
Id.
at 112-13. The majority cited no precedent for its ruling; and insofar as we can determine, the decision has only been followed by a single district court within the Fourth Circuit.
See Corrigan v. United States,
In the present case, the district court declined to accord suzerainty to
Flannery,
concluding that the future-care expenses and lost earning capacity were not unavoidably duplicative.
Reilly I,
1. Flannery: Shaky Underpinnings. In the first place, we doubt the wisdom of the Flannery rule — a “rule” which, with respect, is little more than an ipse dixit. To be sure, the prudential policies which underlie the law of torts are uncomfortable with the prospect of windfalls: compensatory damages are meant to compensate, and duplicative recoveries, which by definition overcompensate, are disfavored. See supra note 12. Yet, duplication cannot entirely be avoided. Every time that a tort claimant is hospitalized for treatment of injuries, she “saves” on certain personal expenditures. Her meals are provided by the hospital, thus reducing her food budget; she spends her time in a hospital gown, thus reducing her dry cleaning expense; utilities come with the accommodations, thus minimizing the costs of heat, light, and power at her residence. Despite this “duplication,” it has never been suggested that the tortfeasor should be allowed to insist that his victim account for these savings and deduct them from the amount of the hospital bill when proving her damages.
The reasons why such offsets are not accepted practice, we suggest, have both pragmatic and equitable roots. From a practical standpoint, the difficulties in attempting to prove such offsets are enormous. Unless we are prepared to say that damages must now be proved with slider-ule precision — an approach which this court has never adopted,
see, e.g., Knightsbridge Marketing Services, Inc. v. Promociones y Proyectos, S.A.,
In view of these concerns, we find Flan-nery to rest on very shaky underpinnings and decline to adopt it as a model for this circuit.
2.
No Clear Error.
Because the case at bar is distinguishable from
Flannery,
affirmance of the allegedly duplicative portion of the award does not depend entirely upon our willingness to repudiate the
Flannery
principle. In
Flannery,
the duplication was apparently not disputed, arguably due to the fact that plaintiff’s condition was such as to require “little skilled medical care” during the remainder of his life.
Flannery,
The question of whether — and if so, to what extent — the challenged components of the award are unjustly duplicative is, in this case, principally one of fact. That being so, we review the trier’s factfindings, including the determination of damages, only for clear error.
See, e.g., United States v. Ven-Fuel, Inc.,
Here, there may well have been, as appellant argues, various permissible views of the proof vis-a-vis the purportedly dupli-cative nature of plaintiffs’ recovery. Yet it was the district judge’s prerogative, indeed, his duty, to choose among these conflicted inferences. From aught that appears, he did his duty: he concluded that there was no impermissible doubling of damages as contended by the government; the supposedly overlapped components were “separate and distinct.”
Reilly I,
B. Calculation of the Award.
The government insists that the district court’s calculation of lost earning capacity was flawed in divers ways. We analyze the three most promising of these initiatives.
1.
Delayed Entrance into the Labor Market.
Notwithstanding that the lower court purported to project a future income stream and to discount the product to present value,
Reilly I,
Our quarrel is not with the
Nemmers
court but with the government. In the case at bar, unlike in
Nemmers,
plaintiffs’ expert took account of the late-entry assumption in his original discounting, by discounting back from each year’s earnings, beginning in year 2007.
See Reilly I,
*167
2. Heather’s Gender. The government also argues that the calculation of Heather’s prospective lost earnings was defective because it assumed Heather would have been active in the work force for 48 years. In effect, appellant tells us that the trial court erred in rejecting certain Bureau of Labor Statistics (BLS) work/life tables relied upon by the defense expert. These tables showed that a person of Heather-’s age, sex, and assumed education level would, on average, work for only 28 years. Rather singlemindedly, the government expostulates that because it offered evidence (the tables) to support a reduction on this order of magnitude, and no evidence of inaccuracy was presented, the district court was powerless to reject the figures and abjure the diminution. We disagree.
We begin by remarking that appellant’s theory is questionable as a matter of fact. In an environment where more and more women work in more and more responsible positions, and where signs of the changing times are all around us, it can no longer automatically be assumed that women will absent thеmselves from the work force for prolonged intervals during their child-bearing/child-rearing years. Yet we need pursue neither the sexist aspects of the point nor the antiquated premise upon which it rests — for the government’s theory is also wrong as a matter of law.
In this case as in so many others, the district court, while bound to consider the government’s expert testimony as to Heather’s expected work-life, was not required to accept it. Tables of this sort “are merely guides to assist a court or jury in arriving at its verdict.”
Gonyer v. Russell,
Death and taxes, arguably, may be certain; statistics, though often a valuable predictive aid, usually are not. The district court did not commit clear error in refusing to yield to the government’s suggested assumption that a woman, invariably, works less and, therefore, earns less than her male counterpart.
3. The Experts’ Worksheets. A further aspect of the attack on lost earnings relates to the government’s complaint that it was never allowed to see the work papers of plaintiff’s economists, Drs. Wright and Greene. That is apparently true — but a party cannot legitimately complain of lack of access to worksheets when it never sеasonably requested such access. We have combed the record with meticulous attention to detail and find that, although the AUSA asked for Dr. Green’s work papers during his deposition to no avail, there was no appropriate follow-through. The deposition was not adjourned; the AUSA filed no motion to compel the witness to produce the materials, see, e.g., Fed.R.Civ.P. 37(a), or for sanctions, Fed.R.Civ.P. 37(b)(2); and the United States never asked for the experts’ work papers in the conventional manner, that is, by a request for production under Fed.R. Civ.P. 34. All in all, given the govern- *168 merit’s torpor, we cannot improve upon the district court’s summary of the situation:
Defense counsel never filed a request for production, nor did he seek access to the economists’ work sheets on cross-examination. In short, the defense counsel’s failure to obtain the reports of which he complains cannot be attributed to his lacking an opportunity to conduct full discovery.
Reilly I,
We have also examined appellant’s contention that it sought additional discovery in respect to the economists on the eve of trial, thus resurrecting its claim to the worksheets. Despite appellate counsel’s misleading characterizations of what transpired below, the record refutes the claim. In particular, the transcript of the pertinent hearing before the magistrate reflects that the government, having previously deposed the economists, was allowed to rein-terview Dr. Wright. Upon inquiry by the magistrate, the AUSA mentioned that, notwithstanding the interview, “[o]ne phase of the information was not supplied, ... and I want to question [the economist] on it.” Hearing Transcript (Oct. 24, 1986) at 45. No other disсovery requests were voiced. When asked to specify the “one phase,” the AUSA stated: “It is relative to the so-called claim of lost wages of the husband [Peter Reilly].” Id. Plaintiffs denied that they were pressing any such claim, id. at 46, and agreed not to introduce testimony as to any such losses. Id. at 46-47. When questioned as to whether that stipulation ended the matter, the government’s lawyer equivocated. The magistrate then stated:
[I]f you want, [within the next few days], give me specifically what you would like, okay, and the reason that you need it, okay, I will make a ruling and if I rule in your favor, the answer is there is no question you’ll get the right to depose this individual prior to him testifying, ... and if it is some area that there’s a hole and you have got to fill in the hole, I can tell you right now I’m going to let you fill in the hole.
Id. at 52. The magistrate added:
[Tell me] specifically what you’re lacking and why you need it, and don’t make it very formal, I’m not looking for something extremely formal. Right now, I [am] shooting in the dark.
* * * * * *
... [W]hat I’m saying to you, I’d like to know what you want, ... and the reason why you want it.
Id. at 53. From what appears of record, it seems that the government never made any such further specification to the magistrate or to the district court.
This, we think, ends the matter. “The law ministers to the vigilant not to those who sleep upon perceptible rights. [A] litigant ... cannot routinely be rewarded for somnolence and lassitude.”
Puleio v. Vose,
V. AVAILABILITY OF A STRUCTURED PAYOUT
The governmеnt makes two arguments which are related in the sense that both implicate the idea of a structured payout of damages, that is, an award payable over time in periodic installments. 15 In its first sally, the United States suggests that the district court erred in ruling that it was obligated to make the award of damages in *169 the form of a lump sum. Should this onslaught fail, appellant’s backup position is that the court ought to have calculated the size of the verdict in reliance upon the cost of purchasing an annuity sufficient to yield periodic payments mirroring the damages sustained. Neither contention is convincing.
A. Form of Award.
On the first point, the district court concluded that, “in the absence of an agreement by the parties to structure the future-care award, the law leaves the court with no alternative but to order the payment of a lump sum judgment.”
Reilly I,
To our knowledge, the only other circuit which has directly addressed this issue in the context, of an FTC A suit concluded that the common law rule — to the effect that a court’s authority to award damages for personal injuries is limited to making lump-sum judgments — controls “unless and until Congress shall authorize a different type of award.”
Frankel v. Heym,
The authorities advanced by the United States do little to aid its position. The one sentence statement in
Jones & Laughlin Steel Corp. v. Pfeifer,
*170
The government’s second principal authority,
Nemmers v. United States, supra,
is simply inapposite. The Seventh Circuit recognized that where a lump-sum payment is awarded to a third party on the plaintiff’s behalf, the court may safeguard the victim by ordering the recipient of the award to purchase an annuity.
Nemmers,
Defendant, we believe, has placed the cart well in front of the horse. When a tortfeasor loses at trial, then — absent a statute or the parties’ contrary agreement, see supra note 16 — it must pay the judgment in one fell swoop. After the wrongdoer and its funds have been parted, the focus shifts: it cannot be doubted that the court has power (1) to ensure that the recovery benefits the victim, and (2) to exercise strict supervision over investment and use of the funds if the victim is a legal incompetent or otherwise in need of protection. But these verities in no manner support the proposition that the wrongdoer has a right to pay in installments where the plaintiffs are unwilling. Nor does the court have a right to impose a periodic payment paradigm on the parties, over protest, solely to ease the tortfeasor’s burden or to suit some fancied notion of equity.
Because the FTCA represents a waiver of the government’s sovereign immunity, it is to be construed conservatively.
United States v. Sherwood,
B. Evidentiary Value.
We need not linger long over appellant’s alternative assertion. There is an argument to be made for admitting the cost of an annuity to assist the trier in calculating the present value of a future income stream,
see, e.g., Chesapeake & Ohio Ry. Co. v. Kelly,
VI. THE ADMINISTRATIVE CLAIM
As we have already mentioned, see supra note 1, an administrative claim is a prerequisite to prosecution of an FTCA action. Notwithstanding that the case shifts from an administrative to a judicial forum once suit is started, the claim retains importance in various ways. One such way is that the amount sought can act as a ceiling on the plaintiff’s eventual recovery. To be specific, the controlling statute provides that:
Action under this section shall not be instituted for any sum in excess of the amount of the claim presented to the *171 federal agency, except where the increased amount is based upon newly discovered evidence not reasonably discoverable at the time [of] presenting the claim to the federal agency, or upon allegation and proof of intervening facts, relating to the amount of the claim.
28 U.S.C. § 2675(b).
In this instance, appellees submitted their administrative claim in the appropriate format (Form 95) in May 1985 (some 5 months after Heather’s birth). They were represented by counsel at the time. They fixed the amount of the claim at $10,000,-000. This figure was never amended. When asked for the “nature and extent оf injury which forms the basis of this claim,” appellees inserted the following description:
Hypoxic ischemic encephalopathy resulting in seizures, blindness, profound neurological deficit; loss of consortium, emotional distress. Peter Reilly and Donna Reilly sue individually on their own behalf as well as on behalf of their minor child.
Form 95 (appended to plaintiffs’ complaint).
At trial, plaintiffs sought to recover more than the upper limit of the claim. The district court honored their entreaty, setting damages in the aggregate amount of $11,037,964. The court rested disregard of the Form 95 ceiling on its finding that:
Only after May 1985 did it become medically apparent that Heather would never be able to walk or talk, and that she would be able to see only enough to distinguish light from dark.... Given the undisputed medical impossibility of knowing the extent of Heather’s multiple disabilities at the time the administrative claim was filed, I find the experts’ subsequent confirmation that the worst possibilities had materialized to constitute “newly discovered evidence not reasonably discoverable at the time of presenting the claim to the federal agency ...,” 28 U.S.C. subsection 2675(b).
Reilly I,
Because the statute itself renders the state of a claimant’s knowledge (actual or constructive) at the time of presentment of the claim of decretory significance, the mechanics of a § 2675(b) inquiry must be double-barrelled: What should the party have known? When should she have known it? To be binding in this context, knowledge need not be certain. In the same vein, intelligence which serves only to bear out earlier suspicions cannot unlock the FTCA’s narrow escape hatch. Diagnoses which are no more than cumulative and confirmatory of earlier diagnoses are neither “newly discovered evidence” nor “intervening facts” for the purposes of § 2675(b).
See Kielwien v. United States,
*172
On this occasion, the information in question was neither sufficiently new, nor sufficiently unforeseen, nor sufficiently material. By the time the claim was filed, the Reillys were on notice of the global extent of Heather’s injuries and disabilities. The evidence upon which the district court relied to lift the cap was, at bottom, nothing more than “the experts’ subsequent confirmation that the worst possibilities had materialized.”
Reilly
I,
In this regard, the instant case bears an uncanny resemblance to
Low v. United States,
In its pertinent parameters, Low is on all fours with the case at bar. Here, as in Low, the basic severity of the child’s condition was known and recited in the claim form. Dr. Vohr, an examining physician, testified without significant contradiction that, from birth, it was readily apparent that there had been “a significant insult to [Heather’s] brain.” J.A. 437. This conclusion was scientifically confirmed within the first two months of Heather’s lifetime by electroencephalography and computerized axial tomography, and Mrs. Reilly was told that the test results were “grossly abnormal.” Id. at 366. She was also informed from the start that Heather had suffered lack of oxygen to the brain and would require medication to control seismic seizures. Once the EEGs and CAT scans were read, as Dr. Vohr said, it was clear that “this infant [was] at serious risk for neurological sequelae.” Id. at 438. Another physician, Dr. Shaywitz, testified that everyone “knew almost certainly by five months ... that Heather was going to have a damaged nervous system.” Id. at 404. In February 1985, Mrs. Reilly was told by an examining physician that her daughter “would probably be blind, maybe, not totally, but would have problems.” Id. at 381. She admitted that, when she filled out Form 95, she understood that Heather was sightless.
This, we think, was more than enough to put the parents on fair notice to guard against the worst-case scenario when preparing their claim. As in
Low,
the fact
*173
that the degree of disability was uncertain was, in and of itself, inadequate to trigger the exception to § 2675(b). To use the district court’s terminology, “[cjonfirmation that the worst possibilities had materialized,”
Reilly I,
We do not categorize such a construction of the law as unduly harsh. The goal of the administrative claim requirement is to let the gоvernment know what it is likely up against: mandating that a claimant propound a definite monetary demand ensures that “[t]he government will at all relevant times be aware of its maximum possible exposure to liability and will be in a position to make intelligent settlement decisions.”
Martinez v. United States,
The cases relied upon by appellees and the district court do not necessitate a contrary result. For example, in
Joyce v. United States,
We conclude that the district court erred in allowing plaintiffs to recover damages in excess of the cap established in their administrative claim. 19
*174 VII. CONCLUSION
We need go no further. All of the government’s earnest scrabbling avails it but slightly. By and large, the orthography of the litigation spells defeat for its cause. After defendant’s alphabet of error has been recited, and its substance examined, we discern little wrong with the district judge’s handling of this difficult case. Both abecedarian logic and the letter of the law dictate that appellant’s assignments of error, save only one, be written off.
To recapitulate, we rule that the court below acted appropriately in the appointment and use of a technical advisor, the government having waived its right to insist on any incremental safeguards; that, although the court misperceived the interplay between R.I.Gen.Laws § 9-19-34 and the FTCA, the mistake was harmless because the United States did not prove the amount(s) of the claimed offsets; that the award of damages for Heather Reilly’s lost earning potential and estimated future-care expenses was not clearly wrong; and that the lower court was under no obligation, on this record, to consider use of a structured payout or to speculate on the cost of an annuity as an aid to figuring present-value damages. We also hold, however, that the court had no sufficient basis for permitting plaintiffs to recover aggregate damages in excess of the ceiling set by their administrative claim.
The judgment appealed from is affirmed in all respects, except that the district court, on remand, shall reduce the amount of the award in conformity with Part VI of this opinion. All parties shall bear their own costs.
Notes
. 28 U.S.C. § 2675(a) provides in substance that an FTCA action shall not lie unless a claim has first been presented to the appropriate federal agency and denied. If the agency fails to make a final disposition of the claim within six months, however, the claimants are permitted to proceed as though the claim had been rejected. See id.
. The district court secured AO permission, believing such authorization to be essential to appointing a technical advisor.
See Reilly II,
. The state supreme court has since answered the certified questions, explaining that, as a matter of state law, “a plaintiff must suffer physical symptomatology” to recover such damages.
Reilly v. United States,
.The court below held that it had both statutory and inherent authority to appoint a technical advisor.
See Reilly II,
. The rule provides in pertinent part:
The court may on its own motion or on the motion of any party enter an order to show cause why expert witnesses should not be appointed, and may request the parties to submit nominations. The court may appoint any expert witnesses agreed upon by the parties, and may appoint expert witnesses of its own selection.... A witness so appointed shall advise the parties of the witness’ findings, if any; the witness’ deposition mаy be taken by any party; and the witness may be called to testify by the court or any party. The witness shall be subject to cross-examination by each party,....
Fed.R.Evid. 706(a).
. In
Hemstreet,
the expert’s role was that of a technical advisor; the judge "asked [him] to review materials submitted by the parties in connection with various issues raised by those motions to increase the court’s understanding of the technical matters presented.”
. Because we are concerned exclusively with the appointment of a "pure” technical advisor, i.e., one who has not been asked to testify or to receive evidence and make findings, neither Fed.R.Evid. 706 nor Fed.R.Civ.P. 53 come into play. See text supra Part 11(A); see also supra note 4.
. We disagree with the suggestion that a technical advisor should be required, as a matter of course, to write a report. The essence of the engagement, see text supra, requires that the judge and the advisor be able to communicate informally, in a frank and open fashion. Given the freewheeling nature of the anticipated discourse, and the fact that the advisor is not permitted to bring new evidence into the case, requiring a written report in every case would serve no useful purpose.
. As the court was explaining its desire to name a technical advisor, the following colloquy took place:
THE COURT: As I implied before, ... it is a rare occurrence in the Federal judicial [system] that matters of this kind [occur] and I feel that I wanted some further expertise over and above what was involved as far as general concepts. I think I’ve got one idea and I don't know whether or not it is worth the time of day but I want to explore them.
[THE U.S. ATTORNEY]: Sure. We were thinking the same way.
J.A. 573.
. We need not consider the government’s oblique references on appeal to some imagined set-off referable to Medicaid payments. Insofar as we can tell from the record, such an argument was never explicitly raised in the trial court. It is, therefore, waived. We note nonetheless that, even apart from waiver, the point seems of dubious relevance. This appeal does not involve reimbursement for past medical expenses, and there is nothing to suggest that Medicaid will afford coverage for future expenses after collection of the judgment. Moreover, as with CHAMPUS and EAHCA benefits, appellant never proved the amount of the putative Medicaid offset.
. Because we conclude that the government did not prove its entitlement to an offset under state law, we need not reach the interesting question as to whether CHAMPUS and EAHCA benefits come within the purview of an exemp-tive statute such as R.I. Gen. Laws § 9-19-34. We do note in passing that these programs seem strangely far afield from conventional “collateral sources,” and that at least one circuit has ruled that CHAMPUS payments do not qualify for offset under a collateral source law.
See Mays v. United States,
. That the law frowns on permitting an injured plaintiff to obtain full recovery twice for the same damages is not much in doubt.
See, e.g., Freeman v. Package Machinery Co.,
. The collateral source doctrine illustrates much the same principle. That doctrine, still widely in force, generally allows recovery against a wrongdoer for the full amount of damages even though the injured party is also compensated for some or all of the same damages from a different source independent of the tortfeasor (and whose payment, therefore, is “collateral” to him). A principal justification for the rule is that "the wrongdoer does not deserve to benefit from the fortuity that the plaintiff has received or will receive compensation from a[n] [independent] source_”
Overton v. United States,
. The imbrication can occur, as the government points out, in at least two ways. First, because of her future-care program, Heather will never incur certain expenses which would have fallen to her in the work place. Second, the program itself affords what might be termed an alternative (if tragic) lifestyle, thereby offering what would be viewed as in-kind replacement, prepaid, for certain elements of the lifestyle which Heather might otherwise have had.
. We need not dwell on the theoretical underpinnings or suggested structure of such "periodic" awards. We refer the reader with a thirst for further detail to the considerable literature on the subject. See, e.g., Plant, Periodic Payment of Damages for Personal Injury, 44 La.L. Rev. 1327 (1984); Rea, Lump-Sum Versus Peri-odie Damage Awards, 10 J. Legal Studies 131 (1981); Kolbach, Variable Periodic Payments of Damages: An Alternative to Lump Sum Awards, 64 Iowa L.Rev. 138 (1978). Nor need we remark the well-deserved popularity of structured settlements in sizable personal injury cases involving large sums of money.
. Periodic damage awards are permissible in lieu of lump sums in certain situations. They can be made, for instance, if a controlling statute permits,
see, e.g.,
Fla.Stat.Ann. § 768.51(l)(b) (West 1986); Cal.Civ.Proc. Code § 667.7(a) (West 1987); Wis. Stat. Ann. § 655.015 (West 1980 & Supp. 1988);
see also Slater v. Mexican Nat’l R.R. Co.,
. Although we bring coals to Newcastle by the observation, we are constrained to note that, in any event, the government likely waived its rights on this score by neglecting to introduce evidence of the dollar amount(s) of the periodic payments which would have been necessary appropriately to compensate plaintiffs. The plaint that the district court "prevented” the introduction either of such evidence or of evidence anent the cost of a suitable annuity, see text infra Part V(B), is not supported by the record.
. The district court made a further finding to the following effect:
[I]f physical symptomatology turns out not to be a rеquirement of emotional distress recovery or, alternatively, if Mr. Reilly’s suicide attempt constitutes a physical symptom of emotional distress, then the attempted suicide would constitute an “intervening fact[ ], relating to the amount of the claim,” further permitting recovery in excess of the administrative claim’s ad damnum under 28 U.S.C. subsection 2675(b).
Reilly
I,
. Appellant’s argument that the district court should be required to pare the administrative ad damnum further is made up out of whole cloth. Appellant seeks such shrinkage ostensibly to account for elements which were included in the original claim but (i) have proven to be nonrecoverable, e.g., emotional distress, loss of consortium, or (ii) remain problematic, e.g., deprivation of Heather’s society and companionship (see supra note 3). The United States cites no authority which would justify trimming of that sort, or de facto proration, in the circumstances at bar. The administrative claim form did not require plaintiffs to affix a price tag to each element of the damages asserted, and plaintiffs did not do so. The government never asked for a breakdown. Accordingly, plaintiffs are entitled to receive whatever recoverable damages they can prove, up to the limit of the overall claim. In this case, the administrative ad dam-num is a unitary roof which covers the entirety of the damages; there is neither reason nor *174 warrant to fragment it into a series of separate subceilings, according some artificial proportionality to each and consequently, giving each limitative effect.
