The defendant was charged, in a four-count indictment, with giving perjured testimony before a grand jury. G. L. c. 268, § 1. He waived trial by jury and, after a bench trial in the Superior Court, was found guilty on all counts. On each count, he was sentenced to a one-year term in a house of correction, the terms to run concurrently and with the sentences suspended and probation imposed for one year.
On appeal, the defendant argues four claims of error, only one of which has substantial merit. That argument presents the question whether the defendant has been subjected to multiple punishment 1 in violation of the double jeopardy clause. Specifically, the defendant argues that the four statements charged as separate perjuries so overlapped in content as to bar conviction on all four counts.
The facts are not in dispute. In November, 1978, a special grand jury was convened'to investigate allegations of fraud by parties providing services to the Medicaid program of the Department of Public Welfare (Department). One provider under investigation was Bay State Management Company, Inc. (Bay State), which owned and operated eight long term care facilities in Massachusetts, including the Quincy Nursing Home (Quincy). Since at least 1969, Quincy had paid wages to one Emma Boynton as a kitchen employee. The grand jury had information, however, that Boynton did not actually work at Quincy for a number of years when she was on its payroll. Rather, it was alleged that she worked during those years at the personal residence of one Michael Minkin, a director of Bay State.
*393
The vice of this arrangement arises from the fact that Quincy was being reimbursed by the Department for wages paid to its employees. Under regulations of the Rate Setting Commission (Commission), a nursing home providing services for Medicaid is required to file an annual financial report on a form denominated RSC-1. 114.2 Code Mass. Regs. § 2.03 (1978). The Commission uses these reports to determine the rate at which the nursing home will be reimbursed by the Department. See generally
Commonwealth
v.
Cerveny,
Commission regulations, however, forbid reimbursement of any “[ejxpenses which are not directly related to the provision of patient care.” 114.2 Code Mass. Regs. § 2.06(5)(f) (1978). Thus, if Emma Boynton did not actually work at Quincy for a number of years when she was paid as an employee, the expenses reported by Quincy, and consequently the payments made by the Department, would have been improperly inflated for those years. If established, these facts would have been grounds for initiating prosecutions under G. L. c. 266, § 30(1) (larceny by false pretense), G. L. c. 268, § 1A (perjury by written instrument), and G. L. c. 6A, § 35 (falsifying information required to be filed with the Commission). See Commonwealth v. Cerveny, supra at 346-347 & nn.2-4.
On April 10, 1979, the defendant, accompanied by counsel, appeared before the grand jury. He first testified that he had worked at Quincy since May, 1971, that he was head chef and kitchen supervisor, and that he scheduled the hours which Emma Boynton worked. The assistant attorney general (prosecutor) then asked the defendant a series of questions directed at various periods of Boynton’s employment. In substance, the defendant was asked whether Boynton worked at Quincy:
*394 (1) from January 1 through December 31, 1972;
(2) from January 1 through December 31, 1973; 2
(3) from January 1, 1972, through December 31, 1975; 3
(4) from May, 1971, through the present (i.e., April 10, 1979). 4 The defendant answered each question in the affirmative. Each numbered response formed the basis for the perjury charged in the count similarly numbered in the indictment.
At trial, the defendant stipulated that the prosecutor’s questions were material to the grand jury’s investigation. See, e.g.,
Commonwealth
v.
Borans,
*395 1. The defendant’s principal argument is that the convictions on all four counts are flawed on the ground of multiplicity. 6 This argument proceeds on the view that the substance of the perjuries charged in counts 1 and 2 are included within count 3, and the substance of counts 1, 2 and 3 are included within count 4. Because of this, the defendant urges that the convictions on three of the counts should be vacated, leaving one conviction on either count 3 or count 4.
We have found no Massachusetts case which addresses the problem of multiple punishments in the context of perjury. There is considerable case law elsewhere, both Federal and State. Proper analysis of the case calls for a review of those decisions first, followed by discussion of the parties’ contentions seeking (improperly in our opinion) to apply jeopardy principles involving lesser included offenses under the “same evidence” test. We then look to the statute itself to determine whether it was the Legislature’s intent to allow separate convictions for the perjuries here (concluding that it was and that the prosecutor’s choice of questions did *396 not result in improper fragmentation of the offenses). We conclude that, since each count involves a lie about a period of time which is separate and distinct, the four perjuries are not substantially identical and the convictions can stand.
A. Cases on Multiplicity of Perjury Convictions.
The defendant relies on the leading case of
Gebhard
v.
United States,
The Commonwealth concedes that “[t]he offense of perjury may not be compounded by the repetitious asking of the same question.”
Masinia
v.
United States,
As to the overlapping portions of the periods charged, the Commonwealth relies on
United States
v.
Doulin,
Based on these and other cases, the rule which emerges is a strict one. As a practical matter, it appears that individual lies will only constitute the same perjury, thereby barring multiple convictions, where they involve facts which are “substantially identical.”
Masinia
v.
United States, supra.
Likewise, close analysis reveals that multiple convictions will be allowed to stand even where the factual difference between the perjuries is slight. In sum, it appears from these cases that convictions for perjury will only be held reversible on the ground of multiplicity where individual falsehoods are “so related . . . [in] subject-matter . . . [and] so linked and blended together in point of time, as to constitute but one act or transaction, and therefore constitute but one offense.”
Commonwealth
v.
Davenport,
The application of these principles is best illustrated in decisions which vacate one or more convictions on the ground of multiplicity while affirming others as involving distinct perjuries. These cases are set out in the margin. 7 It is signifi *398 cant that the majority of cases find no multiplicity among the convictions. 8 While none of these decisions is dispositive *399 of this case, 9 the general principles stressed therein are not supportive of the defendant’s position on the present facts.
*400 B. Putting Aside Jeopardy Arguments About “Lesser Includeds. ”
The defendant contends that counts 1-3 are, in a factual sense, lesser included charges within count 4. In the defendant’s view, the evidence required to prove the first three counts is also required to prove the fourth, and the application of the “same evidence” test would bar multiple punishment. See
Commonwealth
v.
Gallarelli,
In our view, however, both parties are incorrect in their assumption that the same evidence test controls the result in this case. Whatever bearing factual “realities” may have on the analysis, it is now reasonably settled that the test ultimately focuses on the “elements of the statutory offenses charged.”
Commonwealth
v.
Crocker, supra
at 358.
Cepulonis
v.
Commonwealth,
*401
It appears, then, that the same evidence test “has no application here since a single statute is involved and the issue is whether two [or more] discrete offenses were proved under that statute rather than a single continuing offense.”
Commonwealth
v.
Winter,
C. Unit of Prosecution Authorized by G. L. c. 268, § 1.
Under G. L. c. 268, § 1, “[t]he crime of perjury in a judicial proceeding occurs whenever one ‘willfully swears or affirms falsely in a matter material to the issue or point in question.’”
Miaskiewicz
v.
Commonwealth,
*402
The statute manifests a strong legislative policy against per j ury in j udicial proceedings. The reasons underlying this policy are obvious. Perjury strikes at the heart of our judicial system and constitutes, in fact, “an obstruction of justice,” the “perpetration [of which] well may affect the dearest concerns of the parties before a tribunal.”
United States
v.
Norris,
In view of these concerns, the deterrent purpose of the statute, and the severity of the penalties which it provides, we conclude that, where the other elements of the offenses are present, a separate perjury is committed each time a wilful false statement is made, see
Commonwealth
v.
Geromini, supra
at 63-64, except where such statements are “substantially identical,”
Masinia
v.
United States,
*403
Our conclusion is consistent with the result reached in other Massachusetts cases involving multiple convictions for perjury,
11
and with the reasoning of cases dealing with crimes of similar ilk, which hold that separable criminal acts may be punished as discrete offenses rather than as a single transaction. See
Commonwealth
v.
Beal,
It is also consistent with the view that where the lies are only broadly related to a particular area of inquiry the Legislature did not intend to punish multiple perjuries as a single offense. “To adopt [that] position would permit witnesses, who lie once, to escape punishment for an unlimited number of additional false statements.”
People
v.
Guppy,
Applying these principles, in light of the cases, we conclude that the defendant’s convictions for four perjuries must stand. Although it is true that the extended periods involved in counts three and four create some overlap, each count involves a new lie about a period which is separate and distinct from the others. We are satisfied that the four perjuries are not “substantially identical,” and that the overlap may properly be treated as immaterial to the result. Cf.
Gallinaro
v.
Commonwealth,
Finally, we reject the defendant’s suggestion that the prosecutor improperly fragmented what might have been a single perjury into multiple separate offenses by the manner in which he asked his questions. The generally broad discretion
a
prosecutor possesses with respect to examination before a grand jury is limited by the rule that he may not break down an inquiry in order to “run up a possible perjury sentence indefinitely.”

Gebhard
v.
United States,
2. The defendant argues three additional issues, each of which lacks substantial merit.
A. The defendant claims that the trial judge should have excluded certain testimony given by the Commonwealth witnesses Bardon and Vogel on the ground that it was “recently fabricated,” and that without this testimony there is no evidence that the defendant’s perjuries were wilful and intentional. The fact that these witnesses did not give this
*406
testimony before the grand jury more than a year earlier did not establish that the testimony was recently fabricated since there was no showing that they were asked about the matter at that time. Moreover, the doctrine upon which the defendant relies is not a rule which would require the exclusion of the testimony. See
Commonwealth
v.
Zukoski,
B. The defendant contends that the Commonwealth violated the pretrial conference agreement, see Mass.R.Crim.P. 11,
The Commonwealth first received the information relevant here from Vogel on a Friday and from Bardon on the following Monday. The trial commenced on Tuesday. Bar-don testified on Wednesday, and defense counsel received a copy of the report containing his statements at the conclusion of his direct testimony. Cf.
Commonwealth
v.
Lewin
*407
ski, supra.
Although the judge then offered counsel an opportunity “to defer . . . cross-examination of the witness,” apparently until the following morning, counsel read the report and chose to proceed with his examination. Vogel was the next witness. Although counsel apparently did not receive a copy of the report containing her statements prior to cross-examination, the Commonwealth had previously summarized her testimony in its trial brief, which counsel acknowledged receiving. In addition, the substance of Vogel’s testimony on the point relevant here was identical to that given by Bardon. On these facts, the defendant has failed to show that he was prejudiced by any violation of the pretrial conference agreement. See
Commonwealth
v.
Gilbert,
C. The defendant argues that the thirteen days which elapsed between the end of the trial and the formal entry of the guilty findings manifests that the judge harbored uncertainty inconsistent with findings of guilt beyond a reasonable doubt. On the first day following the trial, however, the judge reported to counsel that he had reviewed the evidence and was “satisfied beyond a reasonable doubt that there has been perjury” as charged. The judge then continued the case for the express purpose of considering, and allowing the parties to research, the question of multiplicity. It is quite clear from the transcript that defense counsel understood the posture of the case at that time and in several subsequent hearings. We are satisfied that the judge harbored no uncertainty as to the defendant’s guilt beyond a reasonable doubt.
Judgments affirmed.
Notes
The defendant’s argument does not focus on the penalties imposed, but on the convictions themselves. The defendant correctly points out that under recent case law multiple convictions will themselves constitute multiple punishment if they involve what amounts to the same offense. He also correctly points out that the imposition of concurrent
sentences
no longer cures a multiple punishment problem.
Commonwealth
v.
Jones,
Following question 2 above, the prosecutor also asked whether Boynton worked at Quincy (a) from January 1 through December 31, 1974, and (b) from January 1 through December 31, 1975. The defendant answered these questions in the affirmative, but the Commonwealth apparently chose not to charge additional perjury counts based on those responses.
Questions 1-3 above, as well as the questions mentioned in note 2, were all asked in identical form. As to each period, the prosecutor asked, “[D]id Emma Boynton work full time every week, all week, in the Quincy Nursing Home excluding vacation and sick time?” These five questions were asked consecutively during the middle portion of the defendant’s testimony.
Question 4 was the prosecutor’s final question to the defendant. It was asked in a form slightly different from the others, beginning “And are you indicating to the grand jury that . . . ?”
Our own review of the transcript reveals that the Commonwealth conceded that Boynton returned to work at Quincy on February 14,1976. Thus, there was no evidence that the statement charged in count 4 was false as to the portion running from that date to April 10, 1979. The Commonwealth did, however, present evidence which supported a finding of falsity as to the remainder of count 4, including the portions which do not overlap with any other count (i.e., May — December, 1971, and January 1 — February 13, 1976). Although the defendant moved below
*395
for a required finding of not guilty, Mass.R.Crim.P. 25(a),
Similarly, the defendant does not suggest that the guilty findings on counts 3 and 4 were based on the portions of those counts which are the same as the other counts, rather than the portions which are different. The trial judge was acutely aware of the problem potentially posed by the overlapping periods in the four counts. There was also evidence which supported findings of guilt on the portions of counts 3 and 4 which are distinct. On these facts, and in a case not decided by a jury, we assume in support of the findings that the trial judge “correctly instructed himself” on the law, absent a showing to the contrary
(Commonwealth
v.
Beaulieu, 3
Mass. App. Ct. 786, 787 [1975]; see
Cummings
v.
National Shawmut Bank,
The defendant also argues that the Commonwealth should have been forced to elect between the counts prior to trial. His motion to compel an “election” was properly denied for the reasons discussed in paragraph 3 of note 9 hereafter.
See
Masinia
v.
United States, supra
(affirming two convictions for statements to grand jury investigating robbery that defendant was not present (1) in Reno, Nevada, in March, 1958, and (2) in jewelry store in Reno on March 20, 1958; but striking conviction for repetition of second denial);
People
v.
Guppy,
See
United States
v.
Tyrone,
We note that the analysis employed in the cases cited in notes 7 and 8, supra, is not consistent throughout. We therefore emphasize that the proper focus of the inquiry under Massachusetts law is not on the prosecutor’s questioning before the grand jury, or on his choice of counts in framing the indictment, but rather on the multiplicity of the defendant’s convictions.
Given the “ancient and important public function” of the grand jury as an investigative body,
Matter of Pappas,
In addition, the Commonwealth is generally free to bring indictments in as many counts as it feels appropriate in the circumstances. Our recognition of this discretion does not alter the disapproval expressed at the “practice of obtaining multiple, repetitious and overlapping . . . [counts] where fewer . . . would suffice . . . .”
Commonwealth
v.
Benjamin,
For these reasons, and because multiple convictions for the same offense now constitute multiple punishment even if concurrent sentences are imposed, the inquiry into multiplicity should focus on the defendant’s convictions.
Under G. L. c. 268, § 1, perjury in the trial of a capital case is punishable by imprisonment “for life or for any term of years,” and perjury in *402 any other case is punishable by imprisonment “for- not more than twenty years.” We note that these penalties have remained unchanged since they first appeared in Rev. Sts. c. 128, § 1 (1836).
In several cases the question of multiplicity was arguably presented by the overlapping perjuries charged therein, but the convictions were affirmed without discussion of that issue. See
Commonwealth
v.
Hollander,
We are also aware of several cases not dealing with perjury which examine overlapping periods concerning two offenses in successive prosecutions. In the circumstances of one case, the first conviction was held not to bar the second.
Commonwealth
v.
Beneficial Fin. Co.,
Our cases express a similar concern. See, e.g.,
Commonwealth
v.
Goldstein,
In closing we note that in the Federal courts it has been the practice “to charge perjury before the grand jury, committed in the course of the same appearance, in a one count indictment with each false declaration set forth in a particular specification.”
