ORDER
HEWITT, Judge.Before the court are Plaintiffs Renewed Motion to Compel (Pl.’s Mot. or motion), defendant’s Response of the United States to Plaintiffs Renewed Motion to Compel Discovery (Def.’s Resp. or response), and defendant’s Motion for Leave to File Additional Response to Plaintiffs Renewed Motion to Compel Discovery. Plaintiff moves the court “for an order compelling [defendant] ... to produce certain documents responsive to [defendant's First Request for Production of Documents to Defendant as to which [defen*90dant] has asserted claims of privilege.” Motion 1. Plaintiff requested that the court conduct an in camera review of all documents subject to the motion, id., and the court has .conducted that review.
I. Background
Plaintiff Deseret Management Corporation (DMC) alleges that the United States, acting through the Internal Revenue Service (IRS or government), erroneously assessed and illegally collected income taxes. Plaintiffs Complaint (Compl.) 1. Plaintiff filed its complaint against defendant on February 3, 2006, id., and the parties have been engaged in the discovery process since then.
On December 20, 2006, plaintiff filed Plaintiffs Motion to Compel Production of Certain Documents Claimed as Privileged and Request for In Camera Inspection By the Court (Pl.’s Orig. Mot. or original motion). Defendant responded on January 8, 2007 by filing its Motion of the United States to Strike Plaintiffs Motion to Compel. After a telephonic status conference held by the court on January 19, 2007, in which the parties agreed to attempt to settle the dispute, the court delivered an order finding moot both the original motion and defendant’s responsive motion. Order of Jan. 19, 2007.
On January 31, 2007, plaintiff filed its Renewed Motion to Compel which, inter alia, requested the court to conduct an in camera review of certain documents as to which defendant had asserted claims of privilege. PL’s Mot. 1. Defendant filed its response on February 2, 2007. Def.’s Resp. 1. Plaintiff argued that defendant’s “claims of privilege with respect to the documents ... cannot stand either because of procedural deficiencies in [defendant’s] assertion of the privilege or because of the apparent fact that the documents do not qualify for privilege protection.” PL’s Mot. 10. Defendant argued that plaintiff was not entitled to the requested documents because they were irrelevant to the case and because they were protected by attorney-client privilege, attorney work product privilege, and deliberative process privilege. Def.’s Resp. 14. The court granted-in-part plaintiffs motion and agreed to conduct an in camera review of the documents that defendant claimed were privileged. Order of Feb. 6, 2007. In connection with its review, the court has also considered arguments made in plaintiffs original motion.
Pursuant to the court’s order, defendant caused to be delivered to the court, unfiled, two sets of the documents sought by plaintiffs motion. Defendant’s privilege logs accompanied the documents, which were marked with the document number and arranged in the order discussed in the privilege logs. The court then reviewed each document together with the related assertion of privilege in the privilege logs.
II. Discussion
A. Attorney-Client Privilege
The attorney-client privilege is properly invoked where:
(1) the asserted holder of the privilege is or sought to become a client; (2) the person to whom the communication was made (a) is a member of the bar of a court [and] ... (b) in connection with this communication is acting as a lawyer; (3) the communication relates to a fact of which the attorney was informed (a) by his client (b) without the presence of strangers (e) for the purpose of securing primarily either (i) an opinion on law or (ii) legal services or (in) assistance in some legal proceeding [and] ... (4) the privilege has been (a) claimed and (b) not waived by the client.
Pac. Gas & Elec. Co. v. United States, 69 Fed.Cl. 784, 810 (2006) (PG & E I) (alterations in original) (citing First Fed. Sav. Bank of Hegewisch v. United States, 55 Fed.Cl. 263, 266 (2003) (First Federal) (citation omitted)). The privilege “encourages complete disclosure of information in the nature of confidential communications by a client to the attorney during the attorney-client relationship.” CIT Group/Equip. Fin., Inc. v. United States, 24 Cl.Ct. 540, 542 (1991) (citation omitted). Moreover, “the attorney-client privilege does not shield all information that a client divulges to an attorney, or vice versa, but rather is limited to instances where legal advice is sought or rendered.” PG &E I, 69 Fed.Cl. at 810 (citing First Federal, 55 Fed.Cl. at 266 (citing In re Grand Jury Subpoena *91Duces Tecum, 731 F.2d 1032, 1037 (2d Cir. 1984))). The privilege “evaporates upon any voluntary disclosure of confidential informa-tion to a third party.” Carter v. Gibbs, 909 F.2d 1450, 1451 (Fed.Cir.1990), superceded in non-relevant part by statute, Pub.L. No. 103—424 § 9(c), 108 Stat. 4361 (1994), as stated in In re EchoStar Commc’n Corp., 448 F.3d 1294, 1300 (Fed.Cir.2006). Furthermore, “the privilege impedes the search for truth and is therefore to be strictly construed.” PG & E I, 69 Fed.Cl. at 811 (citing First Federal, 55 Fed.Cl. at 266 (citing Energy Capital Corp. v. United States, 45 Fed.Cl. 481, 484 (2000))).
The attorney-client privilege applies not only to private individuals, but also to government employees. Communications by the Department of Justice to a client agency and by that agency’s own attorneys to non-attorney personnel seeking or being provided with legal advice are entitled to protection under the attorney-client privilege. See Cities Serv. Helex, Inc. v. United States, 216 Ct.Cl. 470, 1978 WL 8445 (1978) (en banc); Renda Marine, Inc. v. United States, 62 Fed.Cl. 371 (2004); Paalan v. United States, 51 Fed Cl. 738, 753 (2002).
When a party invokes the attorney-client privilege by providing a privilege log, “the description of each document and its contents must be sufficiently detailed to allow the court to determine whether the elements of attorney-client privilege ... have been established.” SmithKline Beecham Corp. v. Apotex Corp., 232 F.R.D. 467, 475 (E.D.Pa.2005) (SmithKline) (alteration in original) (citation omitted). Rule 26(b)(5) of the Rules of the United States Court of Federal Claims (RCFC) provides the appropriate standard:
WTien a party withholds information ... by claiming that it is privileged ... the party shall make the claim expressly and shall describe the nature of the documents, communications, or things not produced or disclosed in a manner that, without revealing information itself privileged or protected, will enable other parties to assess the applicability of the privilege or protection.
RCFC 26(b)(5).1 “The rule does not attempt to define for each case what information must be provided____ Details concerning time, persons, general subject matter, etc. may be appropriate.” Fed.R.Civ.P. 26(b)(5) advisory committee notes (1993 Amendments). “Where descriptions in the privilege log fail to meet this standard, ‘then disclosure is an appropriate sanction.’” Smith-Kline, 232 F.R.D. at 475 (quoting Smithkline Beecham Corp. v. Apotex Corp., 193 F.R.D. 530, 534 (N.D.Ill.2000)).
Plaintiff argues that defendant’s “claims of attorney-client privilege exceed the scope of that privilege.” PL’s Orig. Mot. 17 (capitalized in original). More specifically, plaintiff states that the privilege “ ‘affords protection to confidential communications seeking or rendering legal, rather than business, advice,’ ” id. (citing PG & E I, 69 Fed.Cl. at 811 (citation omitted)), and that the documents for which defendant claims the privilege “may contain substantial amounts of merely ‘business’ rather than ‘legal’ advice,” id. Defendant agrees with plaintiff that the “attorney-client privilege extends only to the solicitation and rendering of legal advice, and does not extend ... to ‘business’ advice.” Def.’s Resp. 16. Defendant asserts that the documents for which it claims this privilege are documents from IRS attorneys that contain “legal advice to their client, and accordingly is protected.” Id.
Defendant delivered to the court “all responsive documents defendant has not produced” that plaintiff has requested. Letter from Eileen J. O’Connor, Assistant Attorney General, Tax Division, U.S. Dep’t of Justice, to Judge Emily C. Hewitt, United States Court of Federal Claims (Feb. 9, 2007) (letter) l.2 Each document is marked with Bates *92numbers that correspond to the descriptions in defendant’s privilege logs. The documents are separated into three sets, each of which has its own privilege log. The first set contains documents marked 0001-0511; the second set contains documents marked SUPP00001-SUPP02661; the third set contains documents marked 2SUPP00001-2SUPP01719.
• The privilege log for the first set of documents' is the Declaration of Margo L. Stevens, the Assistant Chief Counsel (Disclosure and Privacy Law) in the Office of the Associate Chief Counsel of the IRS. This log asserts all claimed privileges, the bulk of which are claims of deliberative process privilege, for the first set of documents. The privilege log for the second set of documents consists of two documents. The first is the First Supplemental Declaration of Margo L. Stevens, and it asserts deliberative process privilege with respect to the documents it describes. All other privileges are made in the second document, Privilege Log for November 22, 2006 Production (As Revised). This document asserts privileges other than deliberative process privilege for the second set of documents and lists the documents as to which the Stevens affidavit raised the deliberative process privilege. The third set of documents also are addressed in two documents: first, the Second Supplemental Declaration of Margo L. Stevens'asserts deliberative process privilege with regard to the documents it describes. Second, Revised Privileged Log for December 7, 2006 Production asserts all other privileges and lists the documents with respect to which the Stevens affidavit raised the deliberative process privilege.
The court has reviewed each of the documents for which defendant claims the attorney-client privilege. Defendant’s claims of the attorney-client privilege with respect to those documents appear to be properly invoked. In particular, the court determines that defendant has met the requirements of RCFC 26(b)(5) by adequately describing the communications and circumstances surrounding the occurrence of the communications between employees of the IRS and the IRS’s attorneys. Those communications qualify as attorney-client communications as required by PG & E I. Therefore, the documents for which defendant claims the attorney-client privilege are protected and are not required to be produced.
B. Work Product Privilege
The work product doctrine, codified for the United States Court of Federal Claims in RCFC 26(b)(3),3 is intended to preserve a zone of privacy in which a lawyer can prepare and develop legal strategy “with an eye toward litigation,” free from unnecessary intrusion by adversaries. Hickman v. Taylor, 329 U.S. 495, 510-11, 67 S.Ct. 385, 91 L.Ed. 451 (1947). The work product doctrine provides for the qualified protection of documents and tangible things prepared by or for a party or that party’s representative “in anticipation of litigation or for trial.” RCFC 26(b)(3). The Restatement (Third) of the Law Governing Lawyers defines “litigation,” as it applies within the work product doctrine, as the following:
Litigation includes civil and criminal trial proceedings, as well as adversarial proceedings before an administrative agency, an arbitration panel or a claims commission, and alternative-dispute-resolution *93proceedings such as mediation or mini-trial. It also includes a proceeding such as a grand jury or a coroner’s inquiry or an investigative legislative hearing. In general, a proceeding is adversarial when evidence or legal argument is presented by parties contending against each other with respect to legally significant factual issues.
Restatement (Third) of the Law Governing Lawyers (Restatement) § 87 cmt. h (2000) (quotation marks omitted).
The work product doctrine is not an absolute bar to discovery of materials prepared in anticipation of litigation. Work product can be produced
upon a showing that the party seeking discovery has substantial need of the materials in the preparation of the party’s case and that the party is unable without undue hardship to obtain the substantial equivalent of the materials by other means. In ordering the discovery of such materials when the required showing has been made, the court shall protect against disclosure of the mental impressions, conclusions, opinions, or legal theories of an attorney or other representative of a party concerning the litigation.
RCFC 26(b)(3).
Thus, Rule 26(b)(3) provides that, even if the party seeking discovery of information otherwise protected by the work product doctrine has made the requisite showing of need and undue hardship, courts must still protect against the disclosure of mental impressions, conclusions, opinions, or legal theories of an attorney and his agents. Stated differently, Rule 26(b)(3) establishes two tiers of protection: first, work prepared in anticipation of litigation by an attorney or his agent is discoverable only upon a showing of need and hardship; second, “core” or “opinion” work product that encompasses the “mental impressions, conclusions, opinion or legal theories of an attorney or other representative of a party concerning the litigation” is “generally afforded near absolute protection from discovery.” Thus, core or opinion work product receives greater protection than ordinary work product and is discoverable only upon a showing of rare and exceptional circumstances.
In re Cendant Corp. Sec. Litig., 343 F.3d 658, 663 (3d Cir.2003) (citations omitted).
Plaintiffs original motion to compel argued that defendant “seeks to protect as work product documents that were clearly not prepared in anticipation of litigation.” PL’s Orig. Mot. 20 (emphasis in original). Plaintiff asserts that documents prepared in the auditing process comprise .“work product [that was] prepared in the ordinary course of the IRS’s business rather than in anticipation of litigation.” Id. Defendant argues that “[t]he government reasonably anticipated litigation on this issue almost from the inception of the audit,” Def.’s Resp. 27, because “[o]nce the audit has begun, the likelihood of litigation increases,” id. at 26. Defendant also states “[t]hat the work product could assist both during the audit phase and during future litigation does not lessen its status as work product, since [RCFC] 26(b)(3) does not limit work product protection when an item can have a dual purpose.” Id.
, Both plaintiff and defendant cite persuasive case law in support of their viewpoints. Plaintiff points to the Tax Court ruling in Bennett v. Commissioner of Internal Revenue, 74 T.C.M. 1144, 1997 WL 695368 (1997) that “ ‘the audit or examination process is not conducted in anticipation of litigation’ unless a matter has been ‘singled out for litigation.’” PL’s Orig. Mot. 20 (quoting Bennett, 74 T.C.M. 1144). In Bennett, the court held that neither party appeared to anticipate litigation prior to the issuance of the notice of deficiency, so it granted plaintiffs motion to compel an expert report that had been generated for the IRS prior to the deficiency notice. Bennett, 74 T.C.M. 1144. Defendant counters by citing United States v. Roxworthy, 457 F.3d 590 (6th Cir.2006) (Roxworthy), which held that the parties did anticipate litigation “because a yearly IRS audit of [plaintiff] was a certainty due to the company’s size, the transaction at issue,” and the accountants having advised plaintiff that the IRS targeted the type of transaction. Roxworthy, 457 F.3d at 600. The Roxworthy court presents a summary of case law on whether documents produced during an audit *94may be protected by the work product doctrine. “The Fourth Circuit has stated that the protection only applies when ‘the preparer faces an actual claim or a potential claim following an actual event or series of events that reasonably could result in litigation.’” Id. (quoting Nat’l Union Fire Ins. Co. of Pittsburgh v. Murray Sheet Metal Co., 967 F.2d 980, 984 (4th Cir.1992)). The Fifth Circuit offers a somewhat more expansive view of the protection afforded by the work product doctrine, holding that a document prepared by plaintiff “in anticipation of ‘dealing with the IRS’ ... may well have been prepared in anticipation of an administrative dispute and this may constitute ‘litigation.’ ” Hodges, Grant & Kaufmann v. United States, 768 F.2d 719, 719-22 (5th Cir.1985). In United States v. Adlman, 68 F.3d 1495 (2d Cir.1995), the “Second Circuit held that the district court erred in concluding that the prospect of litigation was too remote for work-product privilege to apply, observing that ‘[i]n many instances, the expected litigation-is quite concrete, notwithstanding that the events giving rise to it have not yet occurred.’ ” Roxworthy, 457 F.3d at 600 (alteration in original) (quoting Adlman, 68 F.3d at 1501).
Plaintiff is a corporation that serves as a holding company for various subsidiaries, including companies that own and operate radio and television stations and provide financial services and life insurance. Plaintiffs Complaint 1 (Compl. or complaint). The sale of the KIRO television station, which lies at the heart of this dispute, is a significant - business transaction involving tens of millions of dollars. See generally Compl. The court believes that, due to the size of the corporation and the significance of the KIRO business transaction, both plaintiff and defendant knew or should have known that the auditing process could lead to litigation. This conclusion is supported by defendant’s contention that “the [IRS] and taxpayer identified early in the audit the KIRO valuation issue as one with respect to which the parties strongly disagreed” and “that[,] in the absence of agreement, the [IRSfwould issue a Notice of Deficiency.” Def.’s Resp. 27. Nothing in plaintiffs filings contradict the foregoing contention.
The court has reviewed each of the documents that defendant claims are privileged under the work product doctrine. Defendant’s claims of the work product doctrine with respect to those documents appear to be properly invoked. In particular, the court determines that defendant has met the requirements of RCFC 26(b)(3) that the documents were produced “in anticipation of litigation.” The guidance of the Second, Fourth, and Fifth Circuits that document production during the IRS’s appeals process may be conducted “in anticipation of litigation” because of the size of the company and the business significance of the transaction appears applicable to the circumstances of this ease. The court determines that the documents defendant seeks to protect were prepared in anticipation of litigation and do contain mental impressions, conclusions, opinions, and legal theories of defendant and defendant’s attorneys. Therefore, the documents for which defendant claims privilege under the work product doctrine are protected and are not required to be produced.
C. Deliberative Process Privilege
The deliberative process privilege “covers ‘documents reflecting advisory opinions, recommendations and deliberations comprising part of a process by which governmental decisions and policies are formulated.’ ” Dep’t of Interior and Bureau of Indian Affairs v. Klamath Water Users Protective Ass’n, 532 U.S. 1, 8, 121 S.Ct. 1060, 149 L.Ed.2d 87 (2001) (Klamath) (quoting NLRB v. Sears, Roebuck & Co., 421 U.S. 132, 150, 95 S.Ct. 1504, 44 L.Ed.2d 29 (1975)).4 *95As the Supreme Court has stated, “[t]he deliberative process privilege rests on the obvious realization that officials will not communicate candidly among themselves if each remark is a potential item of discovery and front page news, and its object is to enhance ‘the quality of agency decisions,’ by protecting open and frank discussion among those who make them within the Government.” Klamath, 532 U.S. at 8-9, 121 S.Ct. 1060 (quoting Sears, Roebuck & Co., 421 U.S. at 151, 95 S.Ct. 1504); see also Scott Paper Co. v. United States, 943 F.Supp. 489, 496 (E.D.Pa.1996) (Scott Paper) (“Th[e deliberative process] privilege recognizes ‘that were agencies forced to operate in a fishbowl, the frank exchange of ideas and opinions would cease and the quality of administrative decisions would consequently suffer.’ ” (citations omitted)); Greenpeace v. Nat’l Marine Fisheries Serv., 198 F.R.D. 540, 543 (W.D.Wash. 2000) (“The accepted rationale [of the deliberative process privilege] is that frank and open discussions within governmental agencies would be ‘chilled’ if the personal opinions and ideas of government personnel involved in the decision-making process were subject to public scrutiny.”).
“The burden of justifying the application of the governmental deliberative process privilege rests with the party seeking to invoke it.” Kaufman v. City of New York, No. 98 Civ. 2648(MJL)(KNF), 1999 WL 239698, at *4, 1999 U.S. Dist. LEXIS 5779, at *10-11 (S.D.N.Y. Apr. 22,1999). “Like all evidentiary privileges that derogate a court’s inherent power to compel the production of relevant evidence, the deliberative process privilege is narrowly construed.” Nat’l Marine Fisheries Serv., 198 F.R.D. at 543 (citations omitted); see also Kaufman, 1999 WL 239698, at *4, 1999 U.S. Dist. LEXIS 5779, at *11 (“The [deliberative process] privilege, as it is in derogation of the search for truth, is not to be expansively construed.”).
In order for a document to be protected from discovery by the deliberative process privilege, it must be both “pre-decisional” and “deliberative.” Jade Trading, LLC v. United States, 65 Fed.Cl. 487, 493 (2005). “To qualify as pre-decisional, the material sought to be protected ‘must address activities [antecedent to the adoption of an agency policy.’ ” Pac. Gas & Elec. Co. v. United States, 70 Fed.Cl. 128, 133 (2006) (PG & E II) (alteration in original) (citing Walsky Constr. Co. v. United States, 20 Cl.Ct. 317, 320 (1990) (Walsky) (quoting Jordan v. U.S. Dep’t of Justice, 591 F.2d 753, 774 (D.C.Cir.1978))).5 “Subjective documents “which reflect the personal opinion of the writer, rather than the policy of the agency1 are considered privileged information because they are predecisional.” LNC Invs., Inc. v. Republic of Nicar., No. 96 Civ. 6360(JFK)(RLE), 1997 WL 729106, at *1, 1997 U.S. Dist. LEXIS 18607, at *2 (S.D.N.Y. Nov. 21, 1997) (LNC Invs.) (citing Lee v. Fed. Deposit Ins. Corp., 923 F.Supp. 451, 456 (S.D.N.Y.1996)) (quoting Coastal States Gas Corp. v. Dep’t of Energy, 617 F.2d 854, 866 (D.C.Cir.1980)). “To qualify as deliberative, the material sought to be protected ‘must address “a direct part of the deliberative process in that it makes recommendations or expresses opinions on legal or policy matters.” ’ ” PG & E II, 70 Fed.Cl. at 133 (quoting Walsky, 20 Cl.Ct. at 320 (quoting Vaughn v. Rosen, 523 F.2d 1136, 1143-44 (D.C.Cir.1975))); see also Kaiser Aluminum & Chem. Corp. v. United States, 141 Ct.Cl. 38,m157 F.Supp. 939, 946 (1958) (Kaiser) (“So far as the disclosure of confidential intraagency advisory opinions is concerned, we conclude that they belong to that class of governmental documents that are privileged *96from inspection as against public interest but not absolutely.”); Jade Trading, 65 Fed.Cl. at 493-94 (“[T]o be deliberative, a document must reflect ‘the give-and-take of the consultative process,’ rather than constituting a ‘body of secret law.’ ” (quoting Vons Cos. v. United States, 51 Fed.Cl. 1, 22 (2001))). “The privilege does not protect factual or investigative material, except as necessary to avoid indirect revelation of the decision-making process.” Scott Paper, 943 F.Supp. at 496 (citations omitted). “Thus, ‘factual findings and conclusions, as opposed to opinions and recommendations’ are not protected.” Reino de Espana v. Am. Bureau of Shipping, No. 03 Civ. 3573(LTS)(RLE), 2005 WL 1813017, at *11, 2005 U.S. Dist. LEXIS 15685, at *34 (S.D.N.Y. Aug. 1, 2005) (quoting Resolution Trust Corp. v. Diamond, 137 F.R.D. 634, 641 (S.D.N.Y.1991), rev’d in part on other grounds, 18 F.3d 111 (2d Cir.1994)).6
The deliberative process privilege is not absolute; rather, the privilege is qualified and “subject to judicial oversight.” Marriott Int’l Resorts, L.P. v. United States, 437 F.3d 1302, 1307 (Fed.Cir.2006) (Marriott); PG & E II, 70 Fed.Cl. at 134; Walsky, 20 Cl.Ct. at 320; Scott Paper, 943 F.Supp. at 496. “After the government makes a sufficient showing of entitlement to the privilege, the court should balance the competing interests of the parties.” Scott Paper, 943 F.Supp. at 496 (citing Redland Soccer Club v. Dep’t of the Army, 55 F.3d 827, 854 (3d Cir.1995)). The plaintiff may overcome the privilege by making “a showing of evidentiary need ... that outweighs the harm that disclosure of such information may cause to the defendant.” Alaska v. United States, 16 Cl.Ct. 5, 11 (1988) (citing CACI Field Servs., Inc. v. United States, 12 Cl.Ct. 680, 687 (1987)); see also Marriott, 437 F.3d at 1307 (“[A] showing of compelling need can overcome the qualified deliberative process privilege.”).
To invoke the deliberative process privilege, “the party resisting discovery must meet several procedural requirements.” Reino De Espana, 2005 WL 1813017, at *12, 2005 U.S. Dist. LEXIS 15685, at *36. “First, the head of the agency that has control over the requested document must assert the privilege after personal consideration.” PG & E II, 70 Fed.Cl. at 134 (quoting Walsky, 20 Cl.Ct. at 320). Alternatively, and recently confirmed as an appropriate practice by the Federal Circuit, “the head of an Agency can, when carefully undertaken, delegate authority to invoke the deliberative process privilege on the Agency’s behalf.” Marriott, 437 F.3d at 1308.7
While some courts have found that the deliberative process privilege may not be asserted by government counsel, Kaufman, 1999 WL 239698, at *4, *5, 1999 U.S. Dist. LEXIS 5779, at *10, *13 (“[S]ince defendants have merely asserted the privilege through counsel, the Court finds that defendants have failed to establish that the governmental deliberative process privilege exists with respect to the withheld documents.”); see also O’Neill, 619 F.2d at 226 (“It has been suggested that it is inappropriate for the privilege to be invoked by attorneys instead of by the department head.”), in the Federal Circuit, invocation of the privilege by government counsel has been found to be appropriate where the counsel holds “a senior position within the Agency and is responsible for *97planning, administering and evaluating the Agency’s disclosure policies and procedures.” Marriott, 437 F.3d at 1308. Notably, the counsel in Marriott was “not directly responsible for or involved in substantive tax litigation, including th[at] ease,” and was a “high ranking Agency official with expertise in the nature of the privilege claim and documents at issue.” Id. The Federal Circuit’s approach in Marriott is consistent with the rationale in other cases holding that counsel are not permitted to invoke the privilege, that is, to ensure that the privilege is invoked as a result of an executive decision about the exigencies of executive management, rather than as a result of trial counsel’s decision about a desirable litigation strategy. The invocation of the privilege in this case appears to the court to fall squarely within the Marriott ruling.
Second, the party seeking protection “must state with particularity what information is subject to the privilege.” Walsky, 20 Cl.Ct. at 320 (citation omitted); see also PG & E II, 70 Fed.Cl. at 135 (citation omitted). In other words, “the information or documents sought to be shielded must be identified and described.” Reino de Espana, 2005 WL 1813017, at *12, 2005 U.S. Dist. LEXIS 15685, at *37 (quotation omitted). Third, “the agency must supply the court with ‘precise and certain reasons’ for maintaining the confidentiality of the requested document.” Walsky, 20 Cl.Ct. at 320 (citation omitted); see also PG & E II, 70 Fed.Cl. at 135 (citations omitted).8 “Blanket assertions of the privilege are insufficient.” Nat’l Marine Fisheries Serv., 198 F.R.D. at 543; see also Kaufman, 1999 WL 239698, at *4, 1999 U.S. Dist. LEXIS 5779, at *12 (“[A] blanket approach to asserting the privilege is unacceptable and is itself grounds for denying invocation of the privilege.”).
The text of RCFC 26(b)(5) also supports the view that assertions of the privilege must provide sufficient information to allow an assessment of the applicability of the privilege to specific documents. The rule provides, in pertinent part:
When a party withholds information otherwise discoverable under these rules by claiming that it is privileged ..., the party shall make the claim expressly and shall describe the nature of the documents ... not produced or disclosed in a manner that, without revealing information itself privileged or protected, will enable other parties to assess the applicability of the privilege ....
RCFC 26(b)(5) (emphasis added). After quoting the language of identical Rule 26(b)(5) of the Federal Rules of Civil Procedure as applied to the deliberative process privilege, the United States District Court for the Southern District of Indiana stated that
the time to make the showing that certain information is privileged is [therefore] at the time the privilege is asserted, not months later when the matter is before the Court on a motion to compel. This requirement is to allow parties to try and resolve discovery disputes prior to Court intervention.
Anderson v. Marion County Sheriff’s Dep’t, 220 F.R.D. 555, 562 n. 5 (S.D.Ind.2004); cf. Miller v. Pancucci, 141 F.R.D. 292, 300 (C.D.Cal.1992) (examining the similar “official information” government privilege and stating that “the party must submit, at the time it files and serves its response to the discovery request, a declaration or affidavit, *98under oath or subject to the penalty of perjury, from the head of the department which has control over the matter”) (emphasis added). Similarly, after citing the same language, the United States District Court for the Eastern District of Pennsylvania stated that “a broad assertion of harm is [therefore] clearly not enough. In fact, the Third Circuit has held that an ‘indiscriminate claim of privilege may in itself be sufficient reason to deny it.’ ” Revelle v. Trigg, No. 95-5885, 1999 WL 80283, at *2, 1999 U.S. Dist. LEXIS 890, at *6 (E.D.Pa. Feb. 2, 1999) (quoting O’Neill, 619 F.2d at 227);9 cf. Miller, 141 F.R.D. at 300 (examining the similar “official information” government privilege and stating that “ ‘[a] general claim of harm to the public interest would not be sufficient to overcome the burden placed on the party seeking to shield material from disclosure.’ ” (quoting Kelly v. City of San Jose, 114 F.R.D. 653, 672 (N.D.Cal.1987))).
Adherence to the foregoing procedural requirements ensures that the documents sought to be protected are in fact “(1) part of the deliberative process by which policies or decisions are formulated; and (2) truly of a predecisional, or advisory or recommendato-ry nature, or expresses [sic] an opinion on a legal or policy matter, or otherwise were reflective of a deliberative process.” LNC Invs., 1997 WL 729106, at *2, 1997 U.S. Dist. LEXIS 18607, at *2.
Plaintiff argues that defendant does not meet the procedural or substantive requirements for the deliberative process privilege. Pl.’s Orig. Mot. 8-16. Plaintiff acknowledges that Margo L. Stevens, the Assistant Chief Counsel in the Office of the Associate Chief Counsel of the IRS, Pl.’s Orig. Mot., Ex. A 1 (Priv. Log 1 or privilege log 1), “is the individual authorized to invoke the deliberative process privilege on behalf of the IRS,” Pl.’s Orig. Mot. 9. However, plaintiff believes that defendant did not timely submit Ms. Steven’s declaration, claiming that it was executed on December 5, 2006, “nearly two weeks after the First Supplemental Log was served.” Id. Plaintiff asserts that the delay in executing the declaration “implies that those claims of privilege are also driven by litigation strategy,” id. at 9, n. 9, “rather than'the mandated executive review and determination,” id. at 9. Plaintiff also argues that defendant’s privilege logs do not suffice because they allegedly “offer[] no explanation for why production of these documents would detract from the quality of its decisions or threaten the ability of those making such decisions to engage in open and frank discussions.” Id. at 11. Plaintiff also claims that defendant’s documents do not meet the “pre-decisional” and “deliberative” requirements for assertion of the privilege because, plaintiff argues, defendant’s valuation of plaintiffs asset is a factual matter, not a policy or legal issue. Id. 13-14. Plaintiff further argues that it has a compelling evidentiary need to review defendant’s documents in order to “demons-trat[e] that the IRS’s original determination was incorrect.” Id. at 15.
With regard to plaintiffs allegation that the Ms. Steven’s declaration was delivered untimely and, therefore, defeats defendant’s claim of the deliberative process privilege, defendant responds that “[s]uch minor and technical delays are not the sort of thing found objectionable in cases.” Def.’s Resp. 19. Defendant cites a number of eases in support of this view. Id. (citing, inter alia, Pac. Gas & Elec. Co. v. United States, 71 Fed.Cl. 205, 208-210 (PG & E III) (holding that the privilege was supported by an affidavit executed after the documents had been identified and withheld); Huntleigh USA Corp. v. United States, 71 Fed.Cl. 726, 727 (2006) (holding that a declaration not executed contemporaneously with the privilege log *99did not render the privilege claim procedurally defective)). In response to plaintiffs allegation that the privilege log is deficient, defendant points to plaintiffs counsel’s statement during an oral argument held shortly after the delivery of the deliberative process privilege log that the log is “the best privilege log I’ve ever seen.” Transcript of Oral Argument on Nov. 29, 2006 (Trans.) 34:13-14. The court also praised defendant’s privilege logs at that oral argument, stating that “what the government has done is something that is of great-benefit and assistance to the court.” Id. at 34:7-9. Defendant states that it is “at a loss to know what plaintiff finds wanting” because “plaintiff provides no examples of what ‘precise and certain reasons’ might look like so as to meet whatever standard plaintiff imagines is to be required.” Def.’s Resp. 20. Defendant asserts that plaintiffs arguments place defendant in a bind
with the [g]overnment as loser whatever we do: [t]o the extent that the affidavit sets out reasons and rationales found proper in decided cases, they are merely a paraphrase thereof, and (according to plaintiff) for that reason invalid. But to the extent that the affidavit fails to set out reasons and rationales found proper in the decided cases, they fail to comport with the law, as expounded in the decided cases.
Id.
Defendant responds to plaintiffs allegations regarding the substance of the logs by stating that “disclosure of any document in which a [government employee suggests or recommends that one course be taken, rather than another, or that this evaluation of the facts is more compelling than some other, will cause such employees — and all other [government agents, officials and employees — to obscure their views and recommendations, and be less than frank in discussing pending cases.” Id. at 21. Defendant asserts that the IRS’s process of determining the amount owed by taxpayers “will be eroded and discouraged by the disclosure of the documents by which it occurs” if defendant’s documents are revealed to plaintiff. Id. Defendant further argues that the privilege is meant to protect frank and open discussion of government decisions and policies, not only “high policy” as it alleges that plaintiff claims. Id. at 22.- Defendant supports this view by citing to Klamath, 532 U.S. at 2, 121 S.Ct. 1060 and Kaiser, 157 F.Supp. at 939. Id.
Finally, defendant argues against plaintiffs assertions that plaintiff has “a particularized need” for the documents by applying a five-factor paradigm from Ferrell v. United States Department of Housing and Urban Development, 177 F.R.D. 425, 429 (N.D.Ill. 1998), which this court cited in PG & E III, 71 Fed.Cl. at 210 n. 6. Id. at 23. Defendant states that “not even one of these factors favors disclosure in the teeth of the deliberative process privilege” because, it alleges, none of the documents • is relevant to any evidentiary issue in the case; all admissible evidence is available from other sources; the government was not a party to the event or transactions relevant to resolving the case; this is a “garden-variety tax refund suit,” not a policy issue; and disclosure of the documents “would chill deliberations ... and hinder frank and independent discussion of policies and decisions.” Id. at 23-24 (emphasis in original).
The court has reviewed each of the documents for which defendant claims deliberative process privilege. Defendant’s claims of the deliberative process privilege with respect to those documents appear to be properly invoked. In particular, the court determines that defendant has met the requirements that the documents were “pre-decisional” and “deliberative,” and that Ms. Stevens executed her affidavit at an appropriate time. The documents for which defendant claims deliberative process privilege are protected and are not required to be produced.
III. “Personal Privacy Privilege”
Defendant claims that a “personal privacy privilege” protects three documents contained within the third set of documents and described in the privilege log titled “Revised Privilege Log for December 7, 2006, Production” (Priv. Log 3) 4, 7. Defendant has not offered any legal authority that defines or sets the standards for such a privilege. If defendant is aware of such legal authority *100and wishes to advance these assertions of privilege, it may file a motion requesting the court to accept its briefing on the subject. If briefing shall be submitted, plaintiff may respond and defendant may then file a reply. If defendant chooses to file a motion, it shall do so on or before April 9, 2007. If defendant has no authority to advance on this point, and any of the documents covered by the claimed “personal privacy privilege” are responsive to plaintiffs request, defendant is directed to deliver the responsive documents to plaintiff immediately.
IV. Missing Descriptions
Defendant’s privilege logs appear to be missing descriptions of and claims of privilege for documents numbered SUPP01701-08 and SUPP02007-22. The court assumes that the omission is an oversight. On or before April 9, 2007, defendant shall deliver to the court descriptions of those documents and the privileges asserted for them. The format shall follow that of the other entries in the privilege logs. If, however, defendant asserts no privilege as to such documents, and any of the documents are responsive to plaintiffs request, defendant is directed to deliver the responsive documents to plaintiff immediately.
V. Conclusion
For the foregoing reasons, and except as stated in parts III and IV above, defendant’s assertions of privilege are SUSTAINED. A set of the documents that defendant submitted to the court upon the court’s request in its order dated February 6, 2007 and the letter of transmittal that accompanied the documents are being delivered to the Clerk of the Court with a copy of this Order. The documents shall be MAINTAINED UNDER SEAL by the Clerk of the Court as part of the record in this case and shall be available to be included in the record of the case in any appeal.
IT IS SO ORDERED.
. Rule 26(b)(5) of the Rules of the United States Court of Federal Claims (RCFC) and Rule 26(b)(5) of the Federal Rules of Civil Procedure (FRCP) are identical. Compare RCFC 26(b)(5) with Fed.R.Civ.P. 26(b)(5). The court therefore uses other federal courts’ interpretations of the FRCP as persuasive authority. Adams v. United States, 391 F.3d 1212, 1218 n. 3 (Fed.Cir.2004) (relying on precedents under the FRCP where, as here, the text of the RCFC "mirrors” the text of an FRCP); see also RCFC, 2002 Rules Committee Note.
. A copy of the letter, as defined in the text, is being transmitted to the Clerk of the Court to be *92stored with a set of the documents. See infra part V.
. RCFC 26(b)(3) provides that:
a party may obtain discovery of documents and tangible things otherwise discoverable under subdivision (b)(1) of this rule and prepared in anticipation of litigation or for trial by or for another party or by or for that other party's representative (including the other party's attorney, consultant, surety, indemnitor, insurer, or agent) only upon a showing that the party seeking discovery has substantial need of the materials in the preparation of the party’s case and that the party is unable without undue hardship to obtain the substantial equivalent of the materials by other means.'
In ordering discovery of such materials when the required showing has been made, the court shall protect against disclosure of the mental impressions, conclusions, opinions, or legal theories of an attorney or other representative of a party concerning the litigation.
RCFC 26(b)(3). Because RCFC 26(b)(3) and FRCP 26(b)(3) are identical, the court relies on interpretation of the latter by other federal courts as persuasive authority. See supra note 1.
. The Court of Claims in Kaiser Aluminum & Chemical Corporation v. United States, 141 Ct.Cl. 38, 157 F.Supp. 939 (1958), is sometimes credited as the first federal case to recognize a deliberative process privilege. Marriott Int'l Resorts, L.P. v. United States, 437 F.3d 1302, 1304 (Fed.Cir.2006) (citing Michael N. Kennedy, Escaping the Fishbowl: A Proposal to Fortify the Deliberative Process, 99 Nw. U.L.Rev. 1769, 1779 (2005)); see also Jade Trading, LLC v. United States, 65 Fed.Cl. 487, 493 (2005) ("The deliberative category of the executive privilege was first articulated and adopted by the Court of Claims in Kaiser Aluminum ....”); CACI Field Sen’s., Inc. v. Unit*95ed States, 12 Cl.Ct. 680, 687 n. 7 (1987) (“According to commentators, the creation of the executive deliberation privilege can be traced to Kaiser.").
. Walsky and other cases cited in this discussion refer to the deliberative process privilege more generally as the "executive privilege.” See Wal-sky Constr. Co. v. United States, 20 Cl.Ct. 317, 319 (1990). As the Federal Circuit recently explained, “[t]he deliberative process privilege is but one of several privileges that generally fall within the scope of the more general ‘executive privilege.’ ” Marriott, 437 F.3d at 1305 n. 3. Therefore, where it appears to the court that a case is specifically referring to the deliberative process privilege even while using the more general phrase "executive privilege,” the court uses the phrase "deliberative process privilege” in order to be more specific as to the privilege to which a case appears to refer.
. "Whenever possible, facts that are separable from the privileged portion of a document should be disclosed.” LNC Invs., Inc. v. Republic of Nicar., No. 96 Civ. 6360(JFK)(RLE), 1997 WL 729106, at *2, 1997 U.S. Dist. LEXIS 18607, at *3 (S.D.N.Y. Nov. 21, 1997) (LNC Invs.) (citations omitted).
. The agency head who asserts the deliberative process privilege or, alternatively, the agency official to whom the authority to assert the deliberative process privilege has been properly delegated, asserts the privilege in the form of a declaration or affidavit. Walsky, 20 Cl.Ct. at 320 n. 3 (citations omitted); see also United States v. O’Neill, 619 F.2d 222, 226 (3d Cir. 1980) ("Usually such claims [of the deliberative process privilege] must be raised by affidavit.” (citation omitted)); Pac. Gas & Elec. Co. v. United States, 70 Fed.Cl. 128, 134 (2006) (PG & E II); Kaufman v. New York, No. 98 Civ. 2648(MJL)(KNF), 1999 WL 239698, at *3, 1999 U.S. Dist. LEXIS 5779, at *9 (S.D.N.Y. Apr. 22, 1999) ("The agency head or his or her authorized designee must invoke the privilege through an affidavit which states, inter alia, that he or she has reviewed each of the relevant documents and provides the reason(s) why preserving confidentiality — rather than the agency's interest in the particular action — outweighs the public interest in disclosure.”).
. Although "[n]one of the decisions binding on this court ... recognizes th[e 'precise and certain reasons’ requirement] as an independent condition for invoking the deliberative process privilege,” Yankee Atomic Elec. Co. v. United States, 54 Fed.Cl. 306, 312 n. 7 (2002) (citations omitted), this requirement is well-established in persuasive federal case law. See, e.g., O’Neill, 619 F.2d at 226; New York ex rel. Boardman v. Nat'l R.R. Passenger Corp., 233 F.R.D. 259, 269 (N.D.N.Y.2006) (quoting LNC Invs., 1997 WL 729106, at *2, 1997 U.S. Dist. LEXIS, at *2; Reino de España v. Am. Bureau of Shipping, No. 03 Civ. 3573(LTS)(RLE), 2005 WL 1813017, at *12, 2005 U.S. Dist. LEXIS 15685, at *37 (S.D.N.Y. Aug. 1, 2005)); Greenpeace v. Nat'l Marine Fisheries Serv., 198 F.R.D. 540, 543 (W.D.Wash.2000); Anderson v. Marion County Sheriffs Dep’t, 220 F.R.D. 555, 562 (S.D.Ind. 2004); Revelle v. Trigg, No. 95-5885, 1999 WL 80283, at *2, 1999 U.S. Dist. LEXIS 890, at *5 (E.D.Pa. Feb. 2, 1999); Scott Paper Co. v. United States, 943 F.Supp. 489, 497 (E.D.Pa. 1996); Resolution Trust Corp. v. Diamond, 773 F.Supp. 597, 604 n. 5 (S.D.N.Y.1991).
. After observing in O'Neill that "[t]he indiscriminate claim of privilege may in itself be sufficient reason to deny it,” O'Neill, 619 F.2d at 227, the Court of Appeals for the Third Circuit continued:
The court when faced with [an indiscriminate claim of deliberative process privilege] cannot make a just or reasonable determination of its validity. Even when the privilege has been asserted by the President of the United States, the Supreme Court has rejected it when it depended “solely on the broad, undifferentiated claim of public interest in the confidentiality of ... conversations” and has refused to extend deference to a President’s "generalized interest in confidentiality.”
O’Neill, 619 F.2d at 227 (alteration in original) (quoting United States v. Nixon, 418 U.S. 683, 706, 711, 94 S.Ct. 3090, 41 L.Ed.2d 1039 (1974)).
