New York State Department of Social Services, DAB No. 1394 (1993) Department of Health and Human Services DEPARTMENTAL APPEALS BOARD Appellate Division SUBJECT: New York State DATE: March 5, 1993 Department of Social Services Docket No. A-92-35 Decision No. 1394 DECISION The New York State Department of Social Services (NYSDSS) appealed a disallowance of $4,493,585 in federal financial participation (FFP) claimed under Title XIX (Medicaid) of the Social Security Act (Act). (NYSDSS originally appealed $5,024,406, but conceded that $530,821 of the disallowance was correct, leaving the above amount in dispute.) This disallowance arose from a review of per diem rates charged for intermediate care facilities for the mentally retarded (ICF/MRs) by the New York State Office of Mental Retardation and Developmental Disabilities (OMRDD). The review was performed by Urbach, Kahn and Werlin, P.C. (UKW) under contract with the Health Care Financing Administration (HCFA) and covered costs included in the base year ending March 31, 1987 for use in reimbursement rates for fiscal year (FY) 1988-89. Based on the results of the review, HCFA determined that NYSDSS had overstated the base year costs by improperly including general State interest costs, claiming depreciation costs for assets whose existence and use could not be verified due to inadequate documentation, incorrectly treating certain assets as abandoned, omitting salvage values from depreciation calculations, incorrectly amortizing certain design costs, including design costs which already had been fully amortized, and making certain mathematical errors in calculation. For the reasons discussed below, we uphold the disallowance in part, reverse it in part, and remand part of the disallowance for further development, as explained in detail in the conclusion section at the end of this decision. Background In order to be eligible for FFP under the Act, state claims for the costs of medical assistance services must be in accordance with an approved Medicaid state plan. Section 1903(a) of the Act. ICF/MR services are included in the definition of "medical assistance" eligible for reimbursement based on rates determined by methods and standards in the plan. Sections 1902(a)(13)(A) and 1905(a) of the Act. The state must find and make assurances to the Secretary that the rates are reasonable and adequate to meet the costs of efficiently and economically operated facilities meeting applicable regulatory requirements. Section 1902(a)(13)(A) of the Act ("Boren Amendment"); 42 C.F.R. Part 447, Subpart C. New York's approved state plan (State plan) provides for payment of services in public ICF/MRs based on a per diem rate determined by methods set out in the plan. See NYSDSS Exhibit (Ex.) 7 (relevant excerpts of New York State plan). The rate for the facilities at issue here (developmental centers with more than 30 beds) is determined by reference to the statewide average rate based on cost reports from developmental centers for a base period, in this case the fiscal year ending March 31, 1987. Certain costs, such as overhead and personal services costs, are adjusted by a trend factor for later periods, while capital costs are not trended. The interest and depreciation costs at issue here were not trended. The State plan provides guidance as to which costs are allowable in calculating the base period costs, and further provides that, except where specific rules are stated in the plan, the Medicare Provider Reimbursement Manual (PRM) will be used as the "major determining factor in deciding on the allowability of costs." NYSDSS Ex. 7, at 22. The plan sets out an overall requirement that, "to be considered allowable, costs must be properly chargeable to necessary client care . . . ." Id. Where both the plan and the PRM are silent, allowability is to be "based on reasonableness and relationship to client care and generally accepted accounting principles." Id. at 23. The UKW review gauged the allowability of depreciation costs included in base period rates for ICF/MR facilities against the standards provided in the State plan. 1/ The costs which HCFA determined to be unallowable based on the UKW review were as follows: 2/ (1) Interest costs on general State borrowing ($4,457,741). (2) Depreciation on assets which were not adequately documented or were not in use for Medicaid purposes ($2,401,398), based on a random statistical sample and examination of OMRDD depreciable assets. (3) Abandonment loss on a facility transferred without cost for use as a public college campus ($1,088,402). (4) Excess depreciation because of the failure to assign any salvage value for depreciated assets ($1,883,997). (5) Design costs amortized over too short a period ($529,357). (6) Design costs which were already fully depreciated by the base year ($8,389). (7) Mathematical errors in the calculation of depreciation on some assets ($4,881). The total was reduced by items which HCFA found had been understated in NYSDSS' claims amounting to $325,352, and then adjusted to reflect the State's 50 percent medical assistance rate for FFP, resulting in the original disallowance amount of $5,024,406. Analysis 1. Allowability of interest on general State borrowing A. Background and arguments Each year, New York State issues tax and revenue anticipation notes (TRANs, also known as "spring borrowing") for short-term borrowing to cover disbursements scheduled to be made during the spring quarter, before sufficient tax revenues are collected. NYSDSS Br. at 9. The proceeds of the TRANs go to New York State's General Fund, from which they are dispensed for payments to local governments and school districts and day-to-day State operations. Id. at 9-10, and exhibits cited therein. A portion of OMRDD's funding in the spring quarter was attributed to proceeds from TRANs. OMRDD included a share of the interest costs for the TRANs, net of the interest income derived by the State on the TRANs proceeds, as part of OMRDD's net capital costs. NYSDSS Ex. 1 (UKW final report at internal ex. H). The proportion of net interest costs allocated to OMRDD was based on the ratio of OMRDD's operational budget to the total State budget for local assistance and State purposes, 3.3496 percent. NYSDSS Br. at 10. NYSDSS argued that these interest costs were properly included as indirect operating expenses under the State plan as interest on working capital indebtedness. NYSDSS argued that resort to the PRM was unnecessary in determining the allowability of the interest costs, since this explicit provision applies. Even if Medicare standards were to apply, NYSDSS argued, the Medicare regulations and PRM requirements would allow these interest costs. HCFA contended that TRANs costs are incurred to manage the State's general cash flow and are unrelated to the operating expenses of particular OMRDD facilities. Further, HCFA argued that interest on TRANs is expressly prohibited under the PRM and cannot be properly allocated to OMRDD through a cost allocation plan (CAP). We conclude that the interest costs were not properly included in the calculation of the reimbursement rates. B. Discussion 1. The State plan does not specifically address these interest costs. The State plan allows "[i]nterest on working capital indebtedness," subject to certain standards. NYSDSS Ex. 7, at 29. The State plan does not define interest on working capital indebtedness, so we look to the PRM for assistance in determining the scope of that phrase. The PRM defines "working capital borrowing" as short term borrowing for "normal operating expenses." PRM,  202.1 (February 1991). 3/ NYSDSS did not persuade us that the "normal operating expenses" of public facilities could be read to include interest costs related to operation of State government generally, rather than borrowing designated for or tied to any particular facility. 4/ Moreover, the discussion of interest in the State plan occurs in a section addressing costs of individual facilities, such as rentals, depreciation, and moveable equipment costs. 5/ By contrast, the indebtedness involved here is remote from the operation of any particular facility, being based on state-wide operations. Thus, we find that the State plan did not expressly address the costs at issue here, since its provision on working capital indebtedness on its face does not include costs of general government borrowing. NYSDSS also argued that we should look to its consistent administrative practice, under which it allegedly included TRANs interest in OMRDD rates for five years before the period at issue, for evidence of the correct interpretation of "working capital indebtedness." NYSDSS Reply Br. at 15. NYSDSS argued that HCFA acquiesced in this practice because a prior HCFA review did not identify these costs as unallowable, even though items of less monetary value were questioned. Id. at 15-16; NYSDSS Supp. Resp. Br. at 4-8; NYSDSS Exs. 42 and 43. HCFA responded that the earlier review dealt with other major problems and simply did not address the allowability of the TRANs interest, even though it appeared in listings of OMRDD cost components. HCFA Supp. Br. at 4-6; Dunstan Affidavit at 3. Administrative practice is relevant to determining whether the state actually had an interpretation of its state plan which it was applying or merely developed one after-the-fact to justify non-compliance with the state plan. However, a "state's interpretation cannot prevail unless it is reasonable in light of the purpose of the provision and program requirements." South Dakota Dept. of Social Services, DAB No. 934, at 4 (1988). We do not find the interpretation proposed by NYSDSS to be reasonable, because the context in the State plan weighs against such a broad interpretation of "working capital indebtedness" and because the Medicaid program is aimed at providing federal funding for the costs of medical services to recipients, not for State cash flow management. Nor do we find HCFA's failure to disallow a cost in an earlier review to be evidence that the cost is allowable under the State plan. In addition, the State plan requires that costs be chargeable to necessary client care. NYSDSS Ex. 7, at 22. NYSDSS failed to demonstrate a necessary connection between the provision of client care in its facilities and the selection of a state-wide cash flow management device. Basically, the "necessity" of incurring the interest costs was unrelated to OMRDD's operations, but rather depended on the State's choice as to the source of its funding to OMRDD. The State is essentially trying to shift some of the costs of raising the revenue to cover its own share of Medicaid funding for these facilities to the federal government. 2. The PRM expressly disallows these interest costs. Since the State plan does not specifically deal with the treatment of these costs, the plan requires us to look to the PRM for guidance. 6/ "Tax anticipation warrants," such as the TRANs at issue here, are expressly named in the PRM as unallowable central service costs. Id. at  2156.1. In addition, the PRM prohibits the inclusion of the costs of financing general government functions in the costs used to determine public facilities' reimbursement rates. PRM, Part 2156 (May 1976). Since the State plan is structured to rely on the PRM, except when specifically providing otherwise, the plan's silence on a subject expressly addressed in the PRM can only be interpreted as acceptance of the PRM rule. We therefore conclude that the interest costs related to TRANs could not properly be included in the reimbursement rate calculations using the standards of the PRM as incorporated in the State plan. 7/ Moreover, we note that the PRM excludes the costs of tax anticipation warrants and general government bonds (even if the proceeds are used to acquire public facilities), despite allowing "[n]ecessary and proper interest on both current and capital indebtedness," including "working capital for normal operating expenses." PRM,  200 and 202.1 (February 1991). This reinforces our conclusion in the prior section that it would be unreasonable to read the State plan allowance of "interest on working capital indebtedness" of a facility as referring to the costs of indebtedness incurred for general government purposes, even if some part of the proceeds eventually benefits a public facility. 3. These interest costs are not allowable as either state-wide costs or indirect facility costs. Furthermore, the State plan requires state-wide costs, such as the interest costs at issue here, to be included in the reimbursement rate only by allocation through a state-wide CAP. NYSDSS Ex. 7, at 20. The interest costs here were not, and could not be, included in a state-wide CAP because they are not allowable under Office of Management and Budget (OMB) Circular A-87, Attachment B, section D.7, which makes unallowable "[i]nterest on borrowings (however represented)." NYSDSS argued that OMB Circular A-87 is inapplicable to this case because prior Board decisions have held that reimbursement rates are determined by methods and cost principles in each state plan rather than by the principles of OMB Circular A-87. NYSDSS Br. at 11, citing Missouri Dept. of Social Services, DAB No. 630 (1985), and North Carolina Dept. of Human Resources, DAB No. 1133 (1990). In Missouri, the state included in the costs on which reimbursement rates for its publicly-owned ICF/MRs were based certain central services costs which were covered by an approved state-wide CAP. It was undisputed that the state calculated the reimbursement rates in accordance with its approved state Medicaid plan. HCFA argued that the costs were unallowable in determining the rates because the department operating the ICF/MRs did not have an approved CAP to distribute the indirect costs to the particular ICF/MRs as allegedly required by OMB Circular A-87. The Board held that a public ICF/MR is not bound to follow the requirements of OMB Circular A-87 in determining reimbursement rates because its terms exempt "publicly-owned . . . providers of medical care." OMB Circular A-87, Attachment A, section A.3; Missouri, DAB No. 630, at 6. In North Carolina, the Board reviewed the use of accrual accounting methods for recording vacation leave for employees of publicly-owned ICF/MRs which, according to HCFA, violated OMB Circular A-87 principles even though they were required by an approved state plan amendment. The Board held that OMB Circular A-87 "cannot be used to override principles made directly applicable for determining rates under the State plan." North Carolina, DAB No. 1133, at 9. We agree that OMB Circular A-87 does not apply directly to the calculation of reimbursement rates for public facilities. The State plan here, however, provides that central services costs may be included in the reimbursement rates only as they are allocated under the state-wide CAP. OMB Circular A-87 does apply to what costs may be included in the CAP. 45 C.F.R.  95.507(a)(2). Furthermore, unlike in the situations in Missouri and North Carolina, the problem here is that the reimbursement rates were not calculated in accordance with the requirements of the State plan. The State plan allows inclusion of overhead 8/ in only two ways: (1) state-wide costs allocated through the state-wide CAP, and (2) other indirect costs of the facilities if the costs are "eligible for reimbursement pursuant to [OMB Circular A-87], provided that other indirect costs may be included pursuant to guidelines specified herein by the commissioner." State Ex. 7, at 20. As discussed above, these costs were not allocated through the state-wide CAP and were not eligible for reimbursement pursuant to OMB Circular A-87. NYSDSS did not point to any specific guidelines allowing inclusion of TRANs interest as an indirect cost, except the mention of "working capital indebtedness," which we have already found to be inapplicable. OMB Circular A-87 is therefore not being used in this case to "override" State plan provisions, as in North Carolina, but rather to comply with them. Thus, TRANs interest does not meet either the State plan requirements as an overhead cost or the PRM requirements for interest costs. NYSDSS also asserted that even if OMB Circular A-87 were applicable, the prohibition on interest on borrowings should not be applied or should be interpreted very narrowly based on its history. NYSDSS Br. at 15, n.9. In this regard, NYSDSS incorporated a brief from another case before the Board, Docket No. A-92-52. NYSDSS's challenges to the interest prohibition were rejected in the decision in that case and are no more persuasive now. New York State Dept. of Social Services, DAB No. 1360 (1992). We also note that NYSDSS in prior challenges to OMB Circular A-87's interest prohibition asserted that the prohibition was intended to be limited to "interest relating to equity capital of contractors, or the analogous `spring borrowing' to raise State funds to cover operations before revenue is realized." New York State Dept. of Social Services, DAB No. 1336, at 20 (1992) (citation omitted). Thus, NYSDSS then asserted that interest on "spring borrowing," the very interest which it now seeks to include as an allowable cost, was within the scope of the interest prohibition. 4. The Boren Amendment does not make these costsallowable. NYSDSS also pointed to the Boren Amendment as intended to vest broad flexibility in the states to develop reimbursement rates without excessive federal oversight, so long as the rates are set in accordance with "the methods and standards in its Medicaid state plan" and the required assurances are made. NYSDSS Br. at 11-12, and cases cited therein. NYSDSS argued that including these interest costs in its approved state plan was within its discretion under the Boren Amendment and that the Boren Amendment requires us to defer to its reasonable interpretation of the State plan and conclude that interest on the TRANs borrowing is allowable as working capital indebtedness. NYSDSS Br. at 14-15. While the Boren Amendment contemplates considerable discretion for the states to decide what methods to include in a state plan, it does not require us to defer to the state interpretation of a plan provision where that interpretation is not reasonably supported by the language of the plan provision or by the context and purpose of the provision. South Dakota Dept. of Social Services, DAB No. 934, at 4 (1988). Here, we have already found that working capital indebtedness on its face does not refer to government-wide borrowing for general purpose funds and that the context relates to costs at the facility level, not the state level. Moreover, the issue here is not whether these costs could have been included by the State plan in the reimbursement rates, but whether the plan did in fact include them, i.e., whether their inclusion was in accordance with the State plan. Again, the State plan requires reliance on the PRM, "except where specific rules concerning allowability of costs are stated" in the plan itself. NYSDSS Ex. 7, at 22. As we discussed above, the PRM expressly disallows tax anticipation interest costs, and no specific rule in the plan allows them. Even under the Boren Amendment, the Board has subjected rate-setting for public, as opposed to private, facilities to "closer scrutiny." South Dakota Dept. of Social Services, DAB No. 934, at 5 (1988). The reason for this concern is that increases in reimbursement rates for state-owned facilities do not raise the cost to the state of operating them, but rather benefit the state by increasing revenue from federal funds. Therefore, the state may be less motivated to scrutinize public facility rates carefully (or may interpret its plan more liberally in regard to public facilities) than to control private facility rates which impact state and federal funding sources similarly. See Massachusetts Dept. of Public Welfare, DAB No. 867, at 9 (1987); Massachusetts Dept. of Public Welfare, DAB No. 730, at 5-6 (1986). These concerns are triggered particularly where, as here, the costs at issue are costs of general government operations which the State is attempting to include in the reimbursement rates of state-owned facilities but not private facilities. In such situations, the Board has upheld (even under the Boren Amendment) disallowance of costs "required to carry out the overall responsibilities of State . . . governments." Arkansas Dept. of Human Services, DAB No. 998, at 4 (1988) (cost of housing state prison inmates who provided services at nursing homes), interpreting OMB Circular A-87, Attachment A, section C.1.a. Absent a specific state plan provision to the contrary, the Board applied this provision to prohibit reimbursement for costs which the State government would have incurred for its general operations, even if the Medicaid program obtained a benefit from them. Id. NYSDSS argued that the TRANs interest is unlike the costs at issue in Arkansas which "otherwise would be borne generally by the state in the absence of the Medicaid . . . program." NYSDSS Reply Br. at 20, quoting Arkansas, DAB No. 998, at 4. By contrast, NYSDSS argued, OMRDD would not need to draw on the TRANs proceeds but for the Medicaid program. This distinction has no validity. The nursing homes in Arkansas would not have needed the services provided by the inmates but for their Medicaid operations. Nevertheless, the state could not take a cost of operating the prison system and transfer it to a federally-funded program. The Boren Amendment vests considerable flexibility in the states in developing rate-setting mechanisms in their state plans, but in no way authorizes a state to ignore its state plan. Therefore, we conclude that, absent clear authority in the approved State plan, NYSDSS here cannot transfer the costs of general State cash flow management to the Medicaid program through the reimbursement rates set for public facilities, simply on the basis that OMRDD draws its State funding through the State General Fund. 5. The interest costs were added on to the reimbursement rates in violation of State planmethods. HCFA argued that NYSDSS's method for including these interest costs in facility reimbursement rates was inconsistent with the overall method described in the plan for calculating the base year costs, and amounted to an improper add-on. HCFA Br. at 28-36. Simply summarized, the plan method calls for calculating a statewide average rate for the base period based on total reimbursable costs to be drawn from cost reports submitted by the facilities (or budget reports for developmental centers operating less than two years), subjected to various specified adjustments (not relevant here), and divided by client days. Overhead costs to be included in the rate are the sum of the state-wide CAP costs and the indirect costs under OMB Circular A-87 or specified in the guidelines. NYSDSS Ex. 7, at 16-20. TRANs interest costs were not on any facilities' cost reports (because they were not allocated down to the facilities' level), nor were they included in the overhead costs in the CAP or facilities' indirect costs (for the reasons discussed above). The State plan did not provide for adding on any other costs. NYSDSS responded that requiring inclusion of the interest costs in the cost reports of the individual facilities would force an allocation process that would be "purely formalistic." NYSDSS Reply Br. at 30. We do not find it an unduly technical requirement of the State plan that costs be derived only from the facilities' cost reports or allowable sources of overhead specified in the plan. Rather, this method prevents the adding on of unallowable costs and is consistent with the intent of the State plan to include costs of particular facilities rather than of the State government as a whole (except as particularly provided regarding CAP costs). Based on the analysis above, we conclude that the State plan does not permit the costs of interest on general state borrowing to be included in calculating the reimbursement rates for ICF/MRs. Therefore, we uphold the portion of the disallowance relating to the interest costs at issue. 2. Depreciation costs on assets the present existence and use of which cannot be fully documented are unallowable. A. Background and arguments This portion of the disallowance was based on a random statistical sample of OMRDD's depreciable assets performed as part of the UKW review. The sample was drawn from OMRDD's Asset Depreciation Report (ADR) for the fiscal year (FY) ending March 31, 1987. The ADR is a list of line items, each of which represents an asset or (more often) group of assets with the associated historical cost and annual depreciation amount. Identifying the specific assets included in a line item requires resort to "detail listings," which are computer printouts of purchase transactions showing purchase price, date, facility location and voucher numbers for each asset. With this information, the original vouchers can be used to locate the asset at a facility. Detail listings are not available for transactions prior to FY 1982-83. As a result, the assets cannot be traced to the original vouchers (although NYSDSS asserted that the original vouchers are still on file) and often cannot be physically located. Thus, NYSDSS admitted that "for multiple-asset line items preceding FY 1982-83, it is normally not possible to obtain the specific information regarding individual assets included within each line item that would permit the location and inspection of the assets." NYSDSS Br. at 55. The ADR included six categories of assets which UKW reviewed. Categories 1, 2 and 3 were land improvements, buildings, and other fixed assets, respectively, which were inventoried in 1971-72 by Joseph Blake & Sons, CPA and are therefore collectively referred to as "Blake Report Assets." Categories 4 and 5 had already been fully depreciated and did not appear in the ADR for the year reviewed. Category 6 included buildings and renovations purchased by the Facilities Development Corporation (FDC), a public benefit corporation responsible for financing new and improved State facilities. Category 7 included equipment assets purchased by the facilities but charged to FDC. Category 8 was equipment purchased directly by the facilities. UKW drew its sample of 417 items from the six categories using a method called cumulative monetary amount sampling, which made the likelihood of selection of a particular item depend on its dollar value. UKW then sought to check documentation on acquisition cost, review the assigned useful life, and physically examine the assets to verify their existence and their use for patient care purposes. 9/ The results fell into two groups: (a) For categories 1, 2, 3 and 6 (Blake report assets and other fixed assets purchased by FDC), UKW successfully located all 321 line items in the sample, but found that 19 were transferred to other agencies or replaced or were otherwise not in use for patient purposes. NYSDSS Ex. 1 (UKW Report at internal exhibit L, sections D.2, D.5, D.6, and D.7). (b) For categories 7 and 8 (equipment assets), UKW was unable to identify the assets covered by 63 of the 96 line items sampled because of lack of documentation, and was able to identify two others that were found not to be in use. Id. at sections D.1 and D.4. 10/ Based on a projection of these results to the universe of depreciable assets, UKW concluded (with 95% confidence) that depreciation costs were overstated by at least $2,401,398. 11/ Id. at internal ex. C. NYSDSS admitted that "some overstatement of depreciation costs" occurred, but asserted that UKW had "greatly exaggerated" the amount, based on the conclusions of a statistical analysis performed for NYSDSS by Analysis and Inference, Inc. (A&I). NYSDSS Br. at 57. A&I challenged the factual bases for finding that 13 of the 19 items disallowed in group (a) were not in use. Id. at 57-58. NYSDSS also challenged the disallowance of the assets in group (b) that could not be located, because it characterized the disallowance as a penalty for recordkeeping violations imposed despite the "virtual certainty" that the assets were properly purchased and used. Id. at 58 (emphasis in original). NYSDSS argued that UKW violated government audit standards by assuming that assets that could not be documented or examined did not exist without making further efforts to account for them. A&I performed an analysis to develop its own assessment of the overstated depreciation, by evaluating how often the assets which could be traced turned out to be in use for program purposes. This analysis rested on the assumption that the assets without documentation sufficient to locate them (most of which were from before FY 1982-83) were as likely to be in use as the assets for which documentation was available. A&I then projected the rate of errors in the examinable assets (as revised by A&I's other calculations) and applied it to those without documentation, arriving at a lower amount of overstated depreciation ($152,605, or $76,303 in FFP) than that found by UKW. We conclude that HCFA properly disallowed the items for which documentation sufficient to permit identification and examination of the assets was not available, as well as the items which NYSDSS admitted were transferred by the relevant FY. However, we remand to HCFA, as explained further below, the portion of the disallowance relating to seven items which NYSDSS alleged were still in use during the relevant FY and one which was replaced. B. Discussion 1. HCFA's findings that certain group (a) assets were transferred, replaced or not in use were accurate as to 11 items but require reassessment as to eight. NYSDSS acknowledged that UKW's findings regarding six of the disallowed items in group (a) were correct, but challenged the factual bases for UKW's findings regarding the other thirteen. NYSDSS Br. at 57-58. NYSDSS' arguments fell into two main categories: (1) as to five items, 12/ NYSDSS admitted that the assets had been transferred but claimed that its depreciation claims were correspondingly reduced by means of a square foot adjustment; (2) as to seven items, 13/ NYSDSS asserted that the assets were associated with buildings that were not transferred until after the end of the base year or were still in use during the base year; and (3) as to one item that was admittedly replaced, NYSDSS claimed that its depreciation claim was proper. NYSDSS Br., at Appendix (App.). a. NYSDSS's adjustments did not correct for improper depreciation claims on transferred assets. NYSDSS asserted that the assets which were admittedly transferred were not included in the depreciation costs used to calculate the reimbursement rates, even though they continued to appear in the ADR. NYSDSS acknowledged that the State plan required that adjustments be made to reflect any disposition of assets resulting in "substantial material changes" in the reimbursement rate. See NYSDSS Ex. 2, at 15. NYSDSS asserted that OMRDD sought to correct the depreciation amounts taken from the ADR to reflect recent disposition of assets, i.e. "material changes," and also made "a reasonable attempt" to delete assets associated with transferred buildings from the ADR. NYSDSS Br., App. at 2-3. However, NYSDSS admitted that transferred assets may remain on the ADR, particularly "in connection with older buildings and multi-building contracts," because they are not identified by building number. Id. at 3. Nevertheless, NYSDSS asserted that an adjustment was made to account for these transferred assets by reducing the reimbursement rate "on a square-footage basis, to reflect any substantial, material transfer of building space." Id. HCFA agreed that a square footage adjustment was taken in the reimbursement rate, but asserted that the adjustment accounted for inactive space and not for the transferred assets remaining erroneously on the ADR. The inactive space adjustment, which OMRDD determined by a survey of the square footage not in use in each facility as a percentage of total square footage, was taken into account in UKW's findings by applying the aggregate percentage to the total amount of overstated depreciation. HCFA Br. at 85. However, HCFA argued that this process did not adequately substitute for actually deleting assets from the ADR. According to HCFA, the square footage adjustment does not reflect the nature of the unused portion of the facility (e.g., a wood frame garage or a concrete and steel building) or identify such associated assets as improvements or components, so that the depreciation still included in the capital rate may be well in excess of actual depreciation costs on non-transferred assets at the facility. In its reply, NYSDSS asserted that the square footage adjustment which it made to the per diem rate to account for demolished or transferred buildings was separate from and in addition to the inactive space adjustment. NYSDSS Reply Br. at 94. However, NYSDSS offered no explanation of how such an additional reduction was calculated apart from the calculation of active/inactive space by facility or how it could accurately account for assets which in several cases could not even be identified or located by building. NYSDSS provided, as an example, a worksheet showing an adjustment for square feet in use at Craig before and after a September 1982 transfer of some of its buildings. NYSDSS Ex. 2, App. C. This worksheet did not demonstrate that the reduction of the square foot space in use at Craig was accurately related to the value and depreciation cost of the particular assets transferred in relation to those remaining in use. Nor did NYSDSS point to anything in the State plan that would permit use of square footage as a rough estimate of the amount of change caused by disposition of these assets. NYSDSS itself asserted that OMRDD made efforts to remove assets related to transferred or demolished buildings from the ADR whenever it could identify them, so clearly OMRDD did not treat any square footage adjustment which it made to be an adequate substitute for the deletion of transferred assets. Essentially, OMRDD deleted assets associated with transferred or demolished buildings when it was able to identify them. In the case of the items at issue, OMRDD failed to identify and delete them because it lacked records adequate to do so. NYSDSS did not demonstrate that any adjustments it made resulted in removing the actual depreciation costs related to those assets that remained erroneously on the ADR from inclusion in the reimbursement rate. Had UKW simply excluded depreciation for all the transferred assets, the disallowance might have duplicated part of the square footage adjustments. However, since UKW accounted for this duplication by reducing the overstated depreciation amount by the inactive space adjustment, no risk of duplication appears. Therefore, we uphold the remaining disallowance for those assets which NYSDSS admitted were transferred out of OMRDD's use by the fiscal year in question. b. The depreciation costs for transferred buildings should be based on the correct dates of transfer. NYSDSS asserted that particular assets were associated with buildings that were not transferred until after the fiscal year in question, and therefore depreciation related to those assets was properly included in the rate calculations. HCFA's response was that "any inaccuracies regarding the dates of transfer of buildings . . . must be attributed to OMRDD" because UKW got the dates from contact people at each facility who were designated by OMRDD. HCFA Br. at 81-82. NYSDSS did not explain how the dates which it alleged to be inaccurate were provided to or obtained by UKW. See NYSDSS Reply Br. at 93, n.52. On the other hand, HCFA provided no support for the factual accuracy of these dates apart from its assertion that OMRDD was responsible for any errors. The dates of transfer for those assets which can be identified by building should be readily verifiable, however. Therefore, we remand to HCFA the portion of the disallowance relating to those assets identified with buildings which NYSDSS asserted were transferred only after the fiscal year in question, in order to permit NYSDSS another opportunity to provide documentation of the correct dates of transfer. c. Depreciation costs on a replaced item must be recalculated. As to the one remaining item (3000001), a fire protection system with associated annual depreciation costs of $5,473, NYSDSS admitted it had been replaced but asserted that OMRDD was entitled to claim the undepreciated basis of the replaced equipment over its useful life. NYSDSS argued that this method was an acceptable alternative to the procedure which HCFA pointed to in the PRM, i.e., adding the undepreciated basis to the cost of the replacement equipment. PRM, 104.11 (November 1985). See HCFA Br. at 85-86. The PRM provision cited by HCFA relates only to determining the basis of assets acquired in whole or part in trade for an asset previously used in the program. In such circumstances, the historical cost of the new asset is determined by adding the undepreciated basis of the old asset to any "boot," such as cash, paid in addition to the trade-in. The parties have not alleged that the fire system was part of such an exchange. The provisions on disposal of assets are at  130-132 of the PRM, which allow, under certain conditions, the claiming of loss upon disposal up to the undepreciated basis. The proper procedures under those provisions depend on the method of disposal, i.e., whether the old fire system was scrapped, traded-in on the new system, sold for salvage value, etc. Since neither party has presented sufficient factual information concerning this asset to determine the method of disposal, we remand this portion of the disallowance to HCFA to allow NYSDSS to provide documentation regarding the method of disposal on which a determination of the proper depreciation adjustment can be made. 3. Depreciation costs for those items in group (b) lacking documentation adequate to permit physical examination are unallowable. a. UKW's review complied with applicable auditing standards. In regard to the disallowed items in group (b), NYSDSS argued that, faced with the difficulty in identifying and locating the assets from before FY 1982-83, UKW was obliged to devise a means of estimating how many of those assets were still in use. In support of this argument, NYSDSS cited an auditing standard stating that "if considering those unexamined items to be misstated would lead to a conclusion that the balance or class contains material misstatement, the auditor should consider alternative procedures that would provide him with sufficient evidence to form a conclusion." American Inst. of Certified Pub. Accountants, Codification of Statements on Auditing Standards,  350.25 (1991). However, the standard does not specify what alternative procedures might be advisable, and certainly does not suggest relying on the error rate of those items which were examinable, as A&I did. 14/ HCFA detailed efforts by UKW staff to retrieve data from FDC and OMRDD files to try to locate descriptions of assets lacking detail listings, pointed out that UKW was instructed to accept computer records without original supporting documents so long as the printouts enabled UKW to physically examine the items, and noted that UKW accepted additional documentation found by OMRDD and performed a second site visit even after its draft report was issued. HCFA Br. at 68-71; NYSDSS Ex. 1 (at internal ex. K) (noting reduction of overstated amount in light of documentation produced after the exit conference). (As HCFA pointed out, UKW did not question the depreciation costs of six assets totaling $6,892,286 which lacked original supporting documentation, but which UKW was able to physically observe and to connect to a specific sampled line item in the ADR.) We find that these procedures were more than adequate and that UKW was not obliged to perform additional procedures in order to form an opinion that the items which could not be identified or located were not adequately documented as in use for Medicaid purposes. b. A&I's alternative estimate of the overstated depreciation is unacceptable. NYSDSS employed A&I to undertake a statistical analysis to substitute for the documentation required to actually locate the missing assets. In support of this methodology, NYSDSS cited several Board cases for the proposition that a claim for FFP can be based on statistical projections. In particular, NYSDSS relied on New York State Dept. of Social Services, DAB No. 1134 (1990), in which we reviewed a claim for FFP in payments on behalf of Medicaid-eligible individuals which had erroneously been charged to state medical assistance only. See NYSDSS Br. at 62. The sample cases were assumed for purposes of the decision to be scientifically selected, to have documentation establishing Medicaid eligibility, and to be the basis of a valid projection to a "homogenous, defined universe." DAB No. 1134, at 9. The Board determined that such a projection could be relied on to determine the amount of a claim as "an auditable determination of what amounts were actually expended for a particular purpose." Id. at 7, n.6. This distinguished DAB No. 1134 from an earlier case, New York State Dept. of Social Services, DAB No. 1012 (1989), where statistical sampling "circumvented specific requirements for documenting Medicaid claims based on disability." New York State Dept. of Social Services, DAB No. 1134, at 3. The Board precedent thus permits statistical sampling to test and validate the documentation of a claim where individual review of the underlying records would be impractical due to volume and cost, but does not permit statistical sampling to replace required documentation that proves non-existent. In the present case, A&I's effort to estimate depreciation costs based on whichever assets could be located is unacceptable precisely because its methods circumvent specific requirements that the assets being depreciated must be documented. We turn first to the State plan to determine the requirements for claiming depreciation costs. The State plan allows depreciation costs for buildings, fixtures and capital improvements "when based upon factors of historical costs and useful lives," and requires that an appraisal based on comparable costs at the time of acquisition be performed whenever historical costs cannot be adequately determined. NYSDSS Ex. 7, at 26. In regard to moveable equipment, furniture, and fixtures, the plan allows depreciation based only on historical cost and useful life, and does not provide an appraisal option. Id. at 28. The State plan thus does not permit inclusion of depreciation costs for equipment assets to which no historical costs can be assigned because OMRDD cannot identify the particular assets involved in order to document their historical cost. 15/ The State plan is silent as to what records must be maintained to support these requirements, so we are required by the plan to turn in that regard to the PRM, which states: The depreciation allowance, to be acceptable, must be adequately supported by the provider's accounting records. . . . Appropriate recording of depreciation requires the identification of the depreciable assets in use, the assets' historical costs . . . , the assets' dates of acquisition, the methods of depreciation, estimated useful lives, and the assets' accumulated depreciation. PRM,  104.9 (November 1985) (emphasis added). The PRM also requires either tagging of major equipment or "alternative records . . . to satisfy audit verification of the existence and location of assets." Id. at  134.8. Thus, we conclude that the State plan, incorporating the PRM, clearly required specific documentation of each depreciated asset sufficient to identify and examine it. NYSDSS, therefore, could not meet this specific documentation requirement by statistical projections showing that other assets which were documented and examinable did exist. Furthermore, the universe which A&I sought to use was not a homogeneous group, but rather included only those assets for which adequate documentation had been found, which were properly depreciated (since A&I excluded items which should not have been depreciated from the universe rather than counting them as errors), and which were disproportionately recent in acquisition. A&I recognized that the validity of this universe depended on the assumption that unexamined assets would have the same "error rate" as those that were available for examination despite the difference in their age. NYSDSS Ex. 30, at 9. Therefore, A&I performed an additional analysis which allegedly found no higher error rate over time (no trend). Id.; NYSDSS Reply Br. at 81-83. A&I's conclusion that errors were not more likely over time is based on two findings: (1) the three errors recognized by A&I among the Category 7 or 8 assets that could be examined showed no trend over time (but admittedly they all dated from the same year), and (2) a random sample of a later (FY 1988-89) ADR, using a survey of the facilities to determine whether the assets in the ADR were in use, found only one "error," an asset not found in use in an ICF/MR. We find no support in these findings for A&I's conclusion that errors were stable over time. The existence of three errors from one year obviously says nothing about the error rate over time. The "random" sample was not in fact random, since it excluded all line items relating to assets predating FY 1982-83, all those for which vouchers could not be located, those for which responses were not received from the facilities, and those not within the scope of the federal audit. Such a sample tells nothing about whether older assets (particularly those dating from the pre-FY 1982-83 time frame that were excluded from the sample) are more likely to be out of service, for one reason or another, than later-acquired assets. Among the reasons that the assumption that pre-FY 1982-83 assets were as likely to be in use as later-acquired assets is faulty are (1) NYSDSS did not explain how these assets would ever be removed from the ADR before being fully depreciated even if they were destroyed, transferred, or disposed of, since none of the individual asset's fates could be tracked, and (2) NYSDSS asserted (in relation to salvage value) that OMRDD's moveable assets are subject to "extraordinary wear and tear" and are usually "trashed or junked" when beyond repair. NYSDSS Br. at 28-29. Under such conditions, we see no basis for assuming that the great majority of equipment acquired before FY 1982-83 would still be in use if located. A&I's approach to the question of error rates over time also demonstrates the essential fallacy in A&I's methods: the restrictive definition employed by A&I in counting an "error." A&I counted as errors only those assets with sufficient documentation to identify and locate them, but found on examination not to be in use for patient purposes. A&I simply removed from the analysis, rather than treating as error, any asset which was not documented or located or not properly depreciated. In effect, A&I created a universe of assets that were properly defined as depreciable with vouchers that could be located, excluding all other assets from the universe, rather than counting them as errors. See NYSDSS Ex. 30, at 5-8. This approach stands the State plan on its head. Under the plan, a provider must show its entitlement to claim depreciation costs on an asset by documenting its present use, identity, location, historical cost, etc. Where OMRDD could not make such a showing after repeated opportunities, UKW properly treated the costs as errors. Nothing in A&I's analysis, which simply showed that documented assets were usually found to be in use upon examination, provides a basis for finding that the costs at issue were correctly claimed. 16/ We therefore uphold the disallowance of depreciation costs on assets which lacked documentation sufficient to permit their examination. Contrary to NYSDSS's assertion, the disallowance here is not a penalty for its recordkeeping deficiencies. Cf. NYSDSS Br. at 59. Rather, in accordance with the State plan, HCFA is reasonably declining to participate in the cost of depreciation on undocumented assets that, as far as can be determined, exist only in a computer listing. 17/ While some of the assets for which documentation permitting identification is unavailable may nevertheless still be in use and properly depreciated, NYSDSS' claim that this is a virtual certainty for the great majority of them is utterly without objective support. We conclude that depreciation costs for assets which cannot be documented or located should have been excluded from the reimbursement rates, and we therefore uphold the portion of the disallowance relating to those costs. 3. A facility transferred without cost for use as a public college campus was not abandoned. A. Background and arguments The Staten Island Developmental Center (SIDC) closed on September 17, 1987, and OMRDD filed a Declaration of Abandonment under which most of the facility, including 35 of 50 buildings on the grounds, was surplused to the New York State Office of General Services (OGS). On the same date, OGS leased the surplused portion of the facility to the New York State Dormitory Authority (a public benefit corporation created by the State legislature) for use by the City University of New York (CUNY). A little over a year later, the same property was deeded to the Dormitory Authority, as had been contemplated in the lease terms, once legal authority was obtained to do so. Id. at 32 and 36-37. The remaining portion of the facility was retained by OMRDD for use for administrative purposes. In addition, OMRDD continued to use some space in five of the 35 leased buildings, vacating them in stages through 1990. See generally NYSDSS Br. at 32-38 (and sources cited therein). 18/ The disallowed costs relating to SIDC consisted of three categories: (1) $387,505 of unrealized depreciation claimed on the buildings transferred to the Dormitory Authority on the basis that they were abandoned, (2) $229,049 of unrealized depreciation claimed on renovations to those buildings which were made in order to comply with Medicaid requirements but were of no value after the transfer, and (3) $471,849 of unrealized depreciation claimed on similar renovations to the buildings retained by OMRDD but no longer used for patient purposes, so that the renovations no longer served any purpose. NYSDSS Br. at 33; NYSDSS Ex. 17. NYSDSS conceded that the third category was properly disallowed and that some amount of the remaining costs (which it estimated at $84,283) should have been excluded from the reimbursement rate to reflect OMRDD's continued use of some of the transferred buildings during the FY at issue. NYSDSS Br. at 44-46. HCFA argued that the buildings were not abandoned, and consequently none of the unrealized depreciation could properly be included in the reimbursement rate calculations under the PRM. 19/ First, HCFA argued, the facility remained throughout under the control of organizations related in one way or another to the State of New York, which had not therefore relinquished all claim to and use of the facility. Second, according to HCFA, a cost-free transfer between governmental entities under these circumstances is treated under the PRM as a donation for which no gain or loss is realized. In any case, HCFA asserted that no loss could be claimed on an abandonment, even if this transfer could be so characterized, because HCFA did not approve the abandonment in advance as required by the PRM. For the reasons explained below, we conclude that the loss claimed on these assets is not allowable. B. Discussion 1. SIDC cannot be treated as abandoned while State-related entities retain title or control. Losses resulting from the abandonment or demolition of an asset may be included in determining allowable cost up to the undepreciated basis of the asset. PRM,  130, 132 (June 1981). 20/ In order to be considered "abandoned" under the PRM, an asset must be permanently retired from all use, and the provider must have relinquished "all rights, title, claim, and possession." PRM,  104.21 (November 1985). HCFA suggested that the requirement of relinquishment was not met here because the Dormitory Authority was a quasi-state agency, and therefore a related organization to the provider, since OMRDD is a part of the State. HCFA Br. at 55, n.24. Under the PRM, costs of related organizations are attributed to the provider, as discussed below. The Board previously considered an analogous relationship between the State and the Urban Development Corporation (UDC), a quasi-public corporation created by State law for the purpose of financing government construction projects, in New York State Dept. of Social Services, DAB No. 1336 (1992). In that case, UDC held title to a building which it leased to OGS for use as NYSDSS headquarters in Albany for 40 years at the end of which title would pass to New York State. Id. at 2. The Board held that the State owned the building to which UDC held title, because UDC was "a component of the State, created by State law, and funded by State bond offerings." Id. at 5. The Dormitory Authority is also created by State law, with a board consisting of public officials and members appointed by the governor, and the power to acquire property in the name of the State. Public Auth. Law, Title 4,  1677-1691 (1992). While the Dormitory Authority is not "a mere arm of the State," and therefore is free of some of the restraints on direct state contracts in its financing of construction projects, it is nevertheless a public benefit corporation "with governmental functions delegated to it by the State." Thompson Construction Corp. v. Dormitory Auth., 264 N.Y.S.2d. 842, at 845 (Sup.Ct. Albany Cty. 1965) (holding Dormitory Authority is not required by statute to award contracts to lowest bidder). Thus, the Dormitory Authority, like the UDC, is a quasi-governmental entity identified with the State. For that reason, just as the payment of "rent" from one State entity to another did not create a "cost" in which the federal government should be required to participate in DAB No. 1336, a transfer of assets from one part of the State to another does not create an abandonment loss for purposes of federal Medicaid reimbursement. The PRM attributes costs of related organizations to providers, in order to prevent the payment of excess profit resulting from less than arm's length bargaining. The same danger arises from treating an asset transferred to a related organization as abandoned. Consequently, such assets are treated as if they were still in the hands of the transferor. Johnson-Mathers Health Care, Inc. v. Blue Cross and Blue Shield, PRRB Dec. No. 83-D49, CCH Medicare and Medicaid Guide, New Developments  32,869 (1983) (holding that a hospital which left a property it had leased from a related party could not claim abandonment unless related party also relinquished all rights); see also Highland View Hosp. v. Blue Cross and Blue Shield, Inc./Blue Cross of Northeast Ohio, PRRB Dec. No. 83-D17, CCH Medicare and Medicaid Guide, New Developments  32,364 (1982) (holding that when county hospital board relocated its activities, its former building was not abandoned because the county still owned and used it). In effect, the State as a whole has not suffered a loss by the transfers between the entities related to it and has not engaged in arm's-length bargaining over the value of the transferred assets. Furthermore, the PRM does not require that the Dormitory Authority be an integrated component of the State in order to be considered a related organization. 21/ The PRM provides that an organization is "related" when the provider "to a significant extent is associated or affiliated with, or has control of, or is controlled by" the other entity. PRM,  1002.1 (December 1982). Control is the power to "directly or indirectly, significantly influence or direct the actions or policies of an organization" and is decided by "the reality of the control . . . not its form or the mode of its exercise." PRM,  1002.3 and 1004.3. The State clearly retains control over the activities of the Dormitory Authority and benefits from the use of its assets for State purposes, such as public educational institutions. 22/ We therefore conclude that the Dormitory Authority is sufficiently related to the State that property transferred to the Dormitory Authority by another State agency (such as OMRDD, via OGS) has not been relinquished for all purposes and cannot be claimed as abandoned. 23/ We discuss in a later section whether OMRDD could claim a loss based on the demolition and gutting of the buildings. 2. The transfer constituted a donation rather than an abandonment. HCFA also argued that SIDC could not be treated as abandoned because the transfer really amounted to a donation for the benefit of the Dormitory Authority, for which no gain or loss may be realized under the PRM. We agree. The PRM treats intergovernmental transfers as "donations" if a "governmental entity acquires the asset without assuming the functions for which the transferor used the asset or without making any payment for it." PRM,  114.1.B (December 1974); 42 C.F.R.  413.134(h)(2). While this provision relates to determining the basis of assets received by donation, a later provision on disposal of assets also states that losses from the "donation . . . of depreciable assets are not included in the determination of allowable cost." PRM, 132.A.2 (June 1981). NYSDSS admitted that the transfer was without payment and that OMRDD functions were not assumed, but asserted that the intergovernmental transfer provisions were inapplicable to the Dormitory Authority. Specifically, NYSDSS denied that the Dormitory Authority was a governmental entity for purposes of PRM,  114.1, because it is not "part of the State government." NYSDSS Br. at 42, n.28. However, we have already rejected this argument above and concluded that, while not an arm of the State, the Dormitory Authority is a governmental entity related to the State. NYSDSS pointed to no authority limiting the term "intergovernmental" to immediate components of the State government, and cases have treated transfers between a county-owned hospital and a state university, for example, as intergovernmental. Univ. of Calif. Irvine Med. Center v. Blue Cross and Blue Shield Assn./Blue Cross of Calif., HCFA Dep. Adm. Dec., CCH Medicare and Medicaid Guide, New Developments,  34,527 (1984). Moreover, factors present here, such as the absence of any arm's length bargaining, the retention of reversionary rights, and restrictions on the transferee's use of the property, have all been found to support the interpretation of a transfer as a donation. See, e.g., PRRB Dec. No. 75-D2, CCH Medicare and Medicaid Guide, New Developments,  27,423 (1975) (finding transfer of a hospital from federal government to city to be a donation, even though done in form of sale with a minimal price, in view of surrounding circumstances). We conclude that a transfer of real estate from a state agency to a public benefit corporation with governmental functions for use as a public university is intergovernmental in nature and that the circumstances here constitute a donation. NYSDSS also argued that these assets had no value and therefore could not be "donations." NYSDSS Br. at 42. NYSDSS' assertion that the assets involved were worthless was based on the fact that most of the buildings involved were either demolished or gutted and heavily renovated by CUNY. However, it was undisputed that the property was never offered to alternative buyers who might have been able to retain more of the original buildings for uses more closely related to their original design, e.g., to use the Medicaid-related improvements for patient care instead of gutting the buildings to redesign them as classrooms or dormitories. The actual market value here was not established by any other means, such as an appraisal based on comparable facilities. The lack of evidence concerning the actual market value distinguishes this case from those relied on by NYSDSS, where providers made substantial unsuccessful efforts to sell deteriorated assets before claiming abandonment. See, e.g., Sisters of St. Francis Health Services, Inc. v. Schweiker, 514 F. Supp. 607, 612-13 (D.D.C. 1981) (finding abandonment of vacant building, despite facility remaining on market, after almost three years without an offer). The ultimate fate of the buildings under the Dormitory Authority only establishes that those assets were not of significant value to the State for other uses. Further, the facility had some value even for CUNY since significant portions of the structures were retained for use. Furthermore, NYSDSS's argument that a donation cannot occur where the gift has no value to the recipient is inconsistent with the HCFA Administrator's treatment of a boarded-up hospital transferred to the Salvation Army without cost. HCFA Ad. Dec., CCH Medicare and Medicaid Guide, New Developments  28,661 (1977). The Administrator found a donation despite the Salvation Army's inability to put the deteriorated building to any use. The Administrator found that a donation is a "contribution to a community effort in which Medicare will not participate by way of reimbursement of claimed losses on depreciated assets," because Medicare is a "program to finance health care costs for Medicare beneficiaries, not costs associated with donations to charity." Id. at 10,317. Similarly, in the present case, Medicaid will not participate in costs that benefit State higher education efforts rather than health care for recipients. We therefore conclude that SIDC was not abandoned, both because the State or a related organization retained a claim to the property and because the transfer constituted a donation. We therefore uphold the portion of the disallowance related to the claim of abandonment of SIDC. 3. OMRDD could not claim a loss based on the demolition, as opposed to abandonment, of the SIDC assets. CUNY ultimately demolished many of the buildings and gutted others, destroying the related renovations. The term "demolition" is defined in the PRM as the "deliberate destruction of a building or other asset resulting in complete loss of economic value (other than scrap value) of the asset." PRM,  104.22 (November 1985). 24/ No loss can be allowed as a result of a demolition unless (1) the asset is replaced (which indisputably did not occur here) or (2) the demolition was approved by HCFA. 42 C.F.R.  413.134(f)(5)(iv); PRM,  132.A.3.a(3) (June 1981). NYSDSS did not directly assert that the demolition was approved, but argued that HCFA's approval for the abandonment could "be considered to have been obtained" because HCFA was aware of and approved of the closing of SIDC. NYSDSS Br. at 39, n.27; NYSDSS Exs. 22-25. The documents on which NYSDSS relied establish that HCFA was informed of OMRDD's intent to close SIDC as part of a plan of correction of deficiencies there and an overall plan to move clients into community facilities. NYSDSS Exs. 22-24. HCFA officials expressed approval of community living arrangements as "moving in the right direction." NYSDSS Ex. 25 (Letter from HCFA Administrator William L. Roper, M.D., dated March 2, 1987). None of the documents submitted suggests that HCFA was informed of the plans to transfer SIDC to the Dormitory Authority or CUNY's plans to demolish or gut most of the buildings, even though NYSDSS stated that these plans were developed long before the closure. See NYSDSS Br. at 35. Furthermore, none of the documents in any way suggests that OMRDD planned to dispose of the assets involved by abandonment or demolition, as opposed to seeking to realize whatever economic value they might retain through sales or other means. We conclude that, since NYSDSS did not obtain HCFA's approval before the demolition of the assets here and did not replace them, the resulting loss is not allowable. 25/ NYSDSS did not request that HCFA consider retroactive approval of the demolition of these assets. Since the issue was not presented by the parties, we do not here decide whether HCFA would have authority to grant retroactive approval. We are not aware of any provision in the State plan or the PRM which would prevent HCFA from granting such approval within its discretion. In grant programs generally, retroactive approval may be granted if "the transaction would have been approved had the organization requested approval in advance." Department of Health and Human Services Grants Administration Manual, chapter 1-105-60, B.1; see Iowa Dept. of Human Services, DAB No. 1340, at 5 (1992). We therefore conclude that the losses relating to buildings that were demolished were properly excluded from the calculation of reimbursement rates. We uphold the portion of the disallowance relating to these loss, subject to HCFA's discretion to consider a request for retroactive approval of the demolitions should NYSDSS make such a request. 4. The status of compliance-related renovations depends on the status of the related buildings. NYSDSS acknowledged that an abandonment loss cannot be claimed where "a provider merely has ceased to use an asset for patient-care purposes; the asset must be permanently retired for any future purpose." Id. at 39, citing 42 C.F.R.  413.134(f)(5)(i) and PRM,  104.21. However, NYSDSS argued that renovations made to improve the facilities in order to maintain certification and meet Medicaid requirements served no function for CUNY, in light of CUNY's plan to either demolish or totally renovate the buildings for its purposes. NYSDSS argued that once a building is not used "for program purposes, improvements that were previously made . . . to satisfy certification requirements and that can be of no further use are also deemed abandoned." NYSDSS Br. at 41. In support, NYSDSS relied on two Provider Reimbursement Review Board (PRRB) decisions. In Monongalia Gen. Hosp. v. Blue Cross and Blue Shield Assn./West Virginia Hosp. Services, PRRB Dec. No. 83-D12, CCH Medicare and Medicaid Guide, New Developments,  32,361 (1983), a provider leased a facility and made substantial leasehold improvements of which it lost possession when it moved out of the building and the lease terminated. In finding abandonment of the leasehold improvements, the PRRB emphasized that the provider never had title to the building and had lost all rights to the improvements and that the lessor to which the building reverted was not a related party. The situation in the present case is precisely the reverse, since the State or a related party held title continuously to the buildings and the improvements. Nothing in the Monongalia case supports the idea that a provider can retain a claim to a building and still take an abandonment loss on improvements to it, simply because the building is no longer used for patient care purposes. HCFA argued, and we agree, that the proper treatment of the compliance-related improvements is the same as the assets to which they are related. The State retains a claim on the improvements as on the buildings through its relationship with the Dormitory Authority, the transfer of the improvements to the Dormitory Authority amounted to a donation (regardless of whether the Dormitory Authority found the improvements useful), and OMRDD did not obtain approval to abandon or demolish the improvements and did not establish that they were without value. Therefore, we conclude that the loss claimed on the compliance-related improvements was not allowable. 3. Salvage values must be assigned to the depreciated assets at issue. A. Background and arguments UKW determined that NYSDSS assigned no salvage value to any of its depreciable assets. Since salvage value is subtracted from the cost of an asset before depreciation is calculated, the failure to assign a salvage value increases the depreciation expenses attributed to that asset. UKW calculated that depreciation costs were overstated by $1,883,997 based on its conclusion that a minimum ten percent salvage value was appropriate under the PRM. NYSDSS argued that the PRM did not specify a particular salvage value. Further, NYSDSS argued that no salvage value could reasonably be expected from OMRDD assets, because (1) they suffer so much abuse from severely mentally retarded clients and (2) OMRDD procedures for surplusing equipment and buildings rarely result in any sales. NYSDSS supported these assertions by a survey of facilities which concluded that revenue from sales of surplused equipment was negligible. In addition, NYSDSS argued that it had never assigned salvage value to its assets, rejecting HCFA's assertion that the Blake Report assigned a five percent salvage value to the assets inventoried there. As explained below, we conclude that it was reasonable to require some salvage value for all assets (absent individual contrary determinations). We further conclude that ten percent was a reasonable minimum salvage value to assign to buildings and fixed assets, and we therefore uphold that portion of the disallowance. However, we conclude that NYSDSS demonstrated that moveable assets were expected to have a lower salvage value, so that five percent would be a reasonable salvage value to assign to the moveable assets, and we remand that portion of the disallowance to HCFA to calculate a corresponding adjustment. B. Discussion 1. Some salvage value should be assigned to virtually all depreciable assets. The PRM provides as follows: Salvage value is the estimated amount expected to be realized upon the sale or other disposition of the depreciable asset when it is no longer useful to the provider. . . . [I]f a provider disposes of its assets when they are in good operating condition, the salvage value would be higher than it might be if the provider used the assets until their inherent life had been substantially exhausted. Virtually all assets have a salvage value substantial enough to be included in calculating depreciation, and only in the rare instance will salvage value be so negligible that it may be ignored. PRM,  104.19 (November 1985). 26/ The salvage value is an estimate at the time of acquisition. Id. An adjustment to net depreciation claimed is made at the time of disposal for any gain or loss based on the actual useful life and salvage value realized. 42 C.F.R.  413.134(f); PRM,  132. 2. Fixed assets should have been assigned a salvage value of ten percent. a. Cost-free transfers of assets do not justify assigning zero salvage value. NYSDSS argued that it expected to realize no salvage value upon disposal of its fixed assets because they were never sold but only transferred to other agencies. In this regard, it is important to remember, as discussed above in relation to SIDC, that the PRM does not permit realizing any gain or loss on assets disposed of as donations through cost-free intergovernmental transfers. To allow NYSDSS to ignore salvage value on its assets because it plans to dispose of them by donations would be to destroy the meaning of this provision by allowing NYSDSS to realize in advance the losses which the PRM forbids it to realize on disposal. In effect, NYSDSS seeks to shift costs to the federal government by a policy of transferring all assets away from the Medicaid-funded agencies to State-run programs rather than seeking to recoup their residual value through bona fide sales. As an example, compare two identical assets bought on the same date for $10,000 with a useful life of ten years each. Asset A is expected to be sold for salvage value of $1,000 at the end of its useful life. Asset B is expected to be transferred to another State agency at no cost. The depreciation on Asset A in which Medicaid would participate would be $10,000 - $1,000 divided over ten years, or $900 a year for 10 years. However, under NYSDSS's approach, the depreciation on Asset B would be $10,000 divided over ten years, or $1,000 a year for ten years. 27/ Not only would the State have received a larger amount of federal funding for depreciation over the years, but the State would receive a cost-free donation of an asset worth a residual value of $1,000 which was partially purchased with federal funds. We agree with HCFA that nothing in the PRM supports NYSDSS' position that the disposal of assets by inter-agency donation evidences that the assets were expected to have no salvage value. Therefore, we reject NYSDSS's arguments that it expects no salvage value on OMRDD's buildings because the only disposals of buildings (Craig, Rome, and SIDC) have been cost-free "inter-agency transfers." 28/ NYSDSS Br. at 30-31. We therefore conclude that salvage values should have been assigned to buildings and fixed assets regardless of OMRDD's use of cost-free transfers in disposing of these assets. b. Ten percent is a reasonable salvage value to assign to the buildings and fixed assets. HCFA derived a ten percent figure from a survey performed by the Inspector General of 30 hospitals, which NYSDSS asserted was inapplicable to public facilities for the mentally retarded. 29/ However, NYSDSS did not present any other basis for determining the appropriate amount of salvage value for its buildings and fixed assets, because it relied on the theory that they had no salvage value since they would be transferred rather than sold. The survey on which the Inspector General's recommendation was based showed that most of the sales were made at a gain, while those which did show a loss resulted in salvage values between 24 and 51 percent of historical cost. NYSDSS Ex. 10, internal attachment 7, at 2-3. The ten percent figure was selected as minimal since it was less than the value realized in any of the hospital sales. Id. Consequently, while the survey sales may well not be representative of the value realizable were the ICF/MR facilities here offered for sale, we conclude that the minimal ten percent figure is a reasonable expectation for buildings to account at least for the residual value of building shells and components even where the facilities are deteriorated. 3. The moveable assets should have been assigned a lower salvage value of five percent. a. OMRDD's survey of surplused equipment demonstrates a lower salvage value than for fixed assets. NYSDSS described OMRDD's written procedures for surplusing moveable assets as beginning with a notice of availability to other OMRDD facilities. If no other facility wants the item, OGS is notified and may arrange a cost-free inter-agency transfer (rarely done for equipment), sell the item at public auction, or authorize a direct sale by the facility. Proceeds of any sale go to the State's general fund. 30/ If the item's condition is considered too bad or it cannot be sold, it is hauled away as trash. NYSDSS Br. at 27-28 NYSDSS asserted that the equipment surplused by OMRDD facilities generally had no residual value. First, the residents subject the equipment to extraordinary abuse (throwing furniture, ripping upholstery, battering equipment, etc.). Second, because of budget constraints, the facilities use the equipment so long as it can be repaired or even used for parts, so that assets are not replaced until they are beyond the point of being saleable even as salvage. To verify this assertion, OMRDD surveyed each of facilities to obtain lists of all items surplused during FY 1986-87 and the total revenue through direct sales of surplus property by the facility. The survey concluded that, for at least 1,797 depreciable moveable assets surplused by OMRDD facilities, the total revenue obtained was $5,307.43, averaging less than three dollars per asset. NYSDSS Br. at 29-30; NYSDSS Ex. 13. On this basis, NYSDSS maintained that OMRDD's depreciable equipment constituted the "rare instance" in which salvage value was so negligible as to be ignored. NYSDSS Br. at 31. HCFA argued that the survey included only items that no OMRDD facility or other State agency wanted, while transferred items may have had residual value. We rejected above the claim that cost-free transfers of fixed assets to other State agencies demonstrated that OMRDD reasonably expected no salvage value on those assets. However, NYSDSS asserted, and HCFA did not deny, that such transfers were infrequent in the case of moveable equipment. 31/ The assets accepted by other OMRDD facilities (as well as any that were transferred to other State agencies) should not have been considered as disposed of, since they were still in use by a related party. HCFA did not deny that the other transactions reported by the facilities represented bona fide sale or scrapping of the assets. Therefore, these transactions would be the proper source for an assessment of fair market value of these assets at disposal, rather than those instances in which less-than-arm's length transfers occurred. Cf. HCFA Br. at 45-46; 42 C.F.R.  413.134b2. 32/ The total amount of revenue derived obviously was still relatively small, although the average amount would be higher than the three dollar figure which was based on dividing the revenue among all surplused equipment, including inter-facility transfers. We conclude that NYSDSS has demonstrated that moveable equipment used in the ICF/MR facilities can be expected to have relatively low salvage values. We recognize that the PRM provides that the salvage value assigned a particular asset may differ based on how intensively the provider expects to use the asset. We further recognize that the PRM does not prohibit a zero salvage value in all cases, since it says "virtually all," rather than "absolutely all" assets will have some salvage value. A zero salvage value might be justifiable in particular instances where the provider so documented for an individual asset. However, we are not persuaded that the PRM contemplated the "rare instance" of zero salvage value being applied in blanket fashion to the wide number and range of moveable assets held by OMRDD. 33/ We realize that the administrative effort and costs involved in making individual assessments of salvage value as to each of the items of equipment used in an OMRDD facility would likely be prohibitive, 34/ so that some uniform figure is preferable. HCFA treated the moveable assets in the same way as the fixed assets discussed above and applied a single ten percent figure. We do not see a reasonable basis for this conclusion, since NYSDSS provided significant evidence that the moveable assets are likely to retain significantly less salvage value. In considering a reasonable uniform figure for moveable assets, we turn to the Blake report below. b. The Blake report assigned a five percent salvage value to moveable assets. HCFA asserted that its contention that OMRDD assets did have salvage value was supported by the Blake report, which considered appropriate salvage values as part of the inventory and appraisal process. HCFA provided an excerpt from the Blake report which substantiated its claim that the assets listed there for SIDC (then called the Letchworth Village) were assigned a salvage value of five per cent (except for carpets and drapes which were assigned zero salvage value). HCFA Br. at 43-44; HCFA Exs. 4 and 5. NYSDSS argued that the assets which were assigned a five per cent salvage value were moveable assets that were fully depreciated before the base year. NYSDSS speculated that the Blake appraisers were not aware of the unusual mistreatment suffered by these assets in OMRDD facilities. NYSDSS Reply Br. at 45. Further, NYSDSS argued that the Blake report did not assign salvage value to the buildings and fixed assets included in categories 1, 2 and 3 of the depreciable assets at issue. NYSDSS Br. at 21-22; NYSDSS Reply Br. at 45-46; NYSDSS Ex. 8. 35/ Neither the State plan nor the PRM prescribe specific amounts or methods for estimating salvage values for moveable assets. Where the State plan and the PRM are both silent, the State plan requires us to weigh the reasonableness of a cost, in relationship to client care and generally accepted accounting principles. NYSDSS Ex. 7, at 23. Therefore, it is appropriate to look at the Blake report figures in weighing reasonableness. We do not find any basis for NYSDSS's speculation that the five percent salvage value assigned to moveable assets in the Blake report resulted from the auditors' ignorance of the abuse of such assets in the facilities. The cover sheets indicate that each item was rated for its condition and the excerpt listing moveable assets shows condition ratings for each asset (most of them as having few if any deficiencies). HCFA Ex. 4, at 16-17; HCFA Ex. 5. It is correct that the particular moveable assets inventoried there are not at issue here, having been fully depreciated. However, NYSDSS did not demonstrate that they differed in any significant way from the later-acquired moveable assets that are at issue. In light of NYSDSS's inability to assess the individual salvage values of the large number of assets involved, the moveable assets inventoried in the Blake report provide a reasonable basis for assigning salvage value to OMRDD's moveable assets. HCFA sought to assign a ten percent salvage value to all assets across the board. However, HCFA relied on the Blake report in other respects and, in fact, stated that the "Blake appraisers obviously conducted their appraisal in accordance with PRM principles" in assigning salvage values to the inventoried assets. HCFA Br. at 44. HCFA never offered any reason for its rejection of the five percent salvage value assigned by the Blake appraisers to most of the moveable assets. We conclude that OMRDD's moveable assets should have been assigned a salvage value of five percent. We remand to HCFA the portion of the disallowance relating to the failure to assign salvage values to moveable assets to recalculate using a five percent salvage value in place of ten percent. 5. Design costs on building renovations should be linked to the useful lives of the buildings as extended by the renovations. A. Background and arguments Design services, such as architectural and drafting services, for existing OMRDD facilities are provided in-house by OGS and charged annually to OMRDD. (New building construction design is contracted out and is not involved here.) OMRDD included these charges in its base year costs by amortizing them over a ten-year period. UKW found that the design costs should have been included in the historical costs of the related assets and amortized over the useful lives of the assets. NYSDSS conceded that the PRM required amortization of design costs over the useful lives of the related assets, but denied that the 40-year useful life which UKW applied as typical was appropriate for renovations and improvements to existing buildings. See generally NYSDSS Br. at 46-47. NYSDSS proposed a 20-year useful life as appropriate, thereby reducing the contested portion of the questioned costs for design cost amortization from $529,357 to $352,904. HCFA insisted that the 40-year period was appropriate. As explained below, we conclude that the design costs issue should be remanded. We also urge the parties to work out a reasonable estimate of the remaining useful life of the buildings to which the renovations relate. B. Discussion The State plan provides that the useful life of an asset over which its historical cost (which both parties agreed included design costs) should be amortized "shall be the higher of the reported useful life or those from the `Estimated Useful Lives of Depreciable Hospital Assets' (1983 Edition) [AHA Guide, NYSDSS Ex. 26]." State Ex. 7, at 26. NYSDSS argued that, because of its method of recording buildings as multiple assets with different useful lives and because of the large number of design projects affecting multiple buildings, it would be unworkable to tie design costs to specific reported useful lives. NYSDSS Reply Br. at 68-71. NYSDSS acknowledged that the AHA Guide does not list useful lives for capital improvements, but turned to the listings for componentized parts of buildings and building services equipment which showed useful lives ranging from 10 to 20 years. Id. at 67. HCFA pointed instead to the listings for concrete and steel buildings which showed useful lives ranging from 25-40 years, and suggested that the maximum figure is appropriate in "the absence of proof to the contrary." HCFA Br. at 62. HCFA also asserted that the PRM provided that improvements that extended the life of an asset are to be capitalized over the remaining useful life of the asset as extended. PRM,  108.2 (February 1982). Therefore, HCFA reasoned, the design costs for projects to renovate buildings would be tied to the useful lives of the buildings, not to particular systems or components of buildings which are unlikely to require design improvements. HCFA Br. at 60-62. We agree with HCFA that the underlying assets for which the design costs are incurred are more likely to be improvements to buildings than to particular components. (NYSDSS described the services as "design functions for building renovation and rehabilitation projects." NYSDSS Br. at 47.) Thus, while improvements such as new floor finishes, air conditioning systems, or toilet partitions may well be installed as part of a renovation project, the design costs at issue are described by NYSDSS itself as on a scale involving one or more buildings, rather than the design of, for example, a particular partition or air conditioner. Cf. NYSDSS Reply Br. at 70. Therefore, under the PRM, the costs should be spread over the useful lives of the buildings affected. Since NYSDSS argued that identifying the reported useful lives of the buildings involved in any particular design project was impractical, HCFA reasonably turned to the AHA Guide figures for the useful lives of buildings. On the other hand, we disagree with HCFA's use of the highest of the range of figures for the useful lives of new buildings as the appropriate period to amortize design costs on renovations, since the relevant period is the remaining useful life of the asset as extended by the improvements. As NYSDSS pointed out, an asset's remaining useful life "by the time renovation becomes necessary (even when that useful life is extended by the renovation) obviously will be no greater than, and likely less than, its initial useful life." NYSDSS Reply Br. at 71-72. Since we find that neither party has provided evidence adequate to justify its proposed amortization schedule, we are remanding this issue. NYSDSS will have the opportunity to provide evidence to HCFA regarding the useful lives of renovated buildings. If HCFA rejects NYSDSS' proposed amortization period, HCFA should provide a better justification than it has here for the application of a higher figure than NYSDSS proposes in the case of these renovations. Also, we urge the parties to review their positions to determine whether they might be able to agree upon a reasonable estimate for the amortization period. 6. Design costs from FY 1976-77 were properly included. A. Background and arguments UKW found that the base year costs for FY 1986-87 included an amortized portion of in-house design costs from FY 1976-77. NYSDSS Ex. 1, at internal exhibit H,  A.5. Since, as discussed above, NYSDSS amortized these costs over ten years, UKW concluded that the costs should have been fully amortized already and that their inclusion in the base year costs overstated costs by $8,389. 36/ NYSDSS responded that its reporting system for asset depreciation, as it functioned prior to FY 1983-84 because of the number and complexity of the assets and the limitations of the older data processing system, caused a lag of one year in claiming depreciation on most assets. 37/ In other words, depreciation claims would not be made until the fiscal year after the one in which an asset was acquired and consequently would end a year later than the normal amortization period (i.e., had that period begun to run on acquisition). NYSDSS Br. at 49-50; NYSDSS Ex. 2, at 13 (Carusone Affidavit). Thus, in the case of the design costs incurred on assets constructed in FY 1976-77, NYSDSS contended that an amortized portion was not included in depreciation costs until FY 1977-78, so that FY 1986-87 was the tenth and final year of amortization. Id. HCFA responded that NYSDSS presented, and UKW's review disclosed, no evidence of the existence of the alleged lag, and that NYSDSS bore the burden of documenting its claim. Therefore, HCFA argued that, in absence of adequate documentation of the lag, the costs should be treated as erroneously included in FY 1986-87. For the reasons given below, we conclude that the base year was the final year of amortization for these design costs and therefore reverse this part of the disallowance. B. Discussion It was not disputed that the costs at issue were properly included in FY 1986-87 (with adjustments for the corrected amortization period), if in fact they had not already been fully amortized. HCFA argued instead that NYSDSS did not document that the alleged lag in reporting existed. The evidence which NYSDSS offered regarding the lag consisted of its response to a draft of the UKW report (NYSDSS Ex. 40) and two affidavits from Leonard Carusone (NYSDSS Exs. 2 and 34). Mr. Carusone has been the Principal Health Care Fiscal Analyst for OMRDD since 1981. NYSDSS Ex. 2, at 1. His job includes gathering the data for and supervising the calculation of OMRDD reimbursement rates. Mr. Carusone described the asset depreciation system before FY 1983-84 and the resulting lag in claiming depreciation, as summarized above. Id., at 11-13. No documentary evidence was provided to demonstrate the effect of the lag. We already have discussed the unavailability of documentation identifying particular assets in the ADR prior to FY 1983-84. While it would certainly be preferable if OMRDD were able to document the assets to which these design costs were attributed and trace their depreciation costs, HCFA did not challenge the existence or allowability of these costs except on the limited basis that the time lag for beginning their depreciation was not documented. We note that the PRM permits a time lag of up to one year after the year of acquisition in which to begin claiming depreciation. In such cases, "[i]n the year of disposal a full year's depreciation is taken." PRM, 118.A.2 (November 1985). The PRM also allows a provider a one-time opportunity to change its method of determining depreciation in the year of acquisition for assets acquired after the change. PRM,  118. The time at which to begin claiming depreciation on a provider's assets is thus intended to be set by policy and to apply across the board to all assets unless changed for all subsequently-acquired assets. Mr. Carusone's affidavit provides credible information from a knowledgeable source regarding the time lag policy and its change in FY 1983-84. HCFA did not provide any reason to disregard Mr. Carusone's explanation of how OMRDD handled first-year depreciation costs, especially since the methods described appear to be in compliance with the PRM. Furthermore, we note that the Blake report, dated January 3, 1972, described the depreciation policy as employing the one-year-time-lag method from the PRM, and therefore charging depreciation beginning in the fiscal year after acquisition. HCFA Ex. 4, at 3. This description corroborates Mr. Carusone's affidavit. Therefore, we conclude that the disallowance relating to these costs should be reversed. 7. NYSDSS did not show that discrepancies in depreciation amounts were due to changes in historical cost. A. Background and arguments UKW found that the amounts claimed for depreciation for 151 assets were incorrect, for a total overstatement of $4,881. NYSDSS Ex. 1, at internal exhibit H,  A.6. NYSDSS asserted that the discrepancies between the amounts calculated by OMRDD and by UKW were not the result of mathematical errors, as found by UKW, but resulted from OMRDD's system for accounting for changes in project costs. NYSDSS alleged that depreciation begins once physical construction of an asset is complete, but that the historical cost for the asset may change after that date, due to contract renegotiation, litigation, etc. If the historical cost rises, the amount claimed for depreciation for any FYs before that change would have been too small. In such cases, not only is a higher amount calculated for subsequent years, but the amount by which any prior year's depreciation was understated (based on the new historical cost) is added as a one-time increase. 38/ HCFA described this explanation as "appealing," but asserted that NYSDSS had failed to provide any documentation to substantiate its assertions that these discrepancies actually relate to later price adjustments. NYSDSS asserted that the adjustments were automatically made by a computer program called the "Project Management System Update" (PMS), and that this process is reflected in the description of the depreciation programs in OMRDD's computer program handbook by a reference to "lump-sum adjustments." NYSDSS Reply Br. at 90. NYSDSS also submitted Mr. Carusone's affidavits describing the adjustment process and suggested that further verification could have been obtained by UKW from the officials who designed and operated OMRDD's computer system. NYSDSS Reply Br. at 91; NYSDSS Exs. 2, 34. However, NYSDSS argued that requiring production of ADR printouts, detail listings or original contracts dealing with these 151 assets would be unreasonable. We conclude that, absent documentation, the overstated depreciation as to these assets was unallowable. B. Discussion The difficulties described above in connecting ADR listings from before FY 1983-84 to specific assets might account for NYSDSS' inability to document the occurrence of later adjustments to historical cost in regard to specific older assets. However, NYSDSS did not provide documentation evidencing such an adjustment for even one of the 151 assets at issue (nor did NYSDSS allege that all of these assets dated from before FY 1983-84). In any case, as we discussed earlier in relation to the assets in the survey which could not be located, NYSDSS has the responsibility to maintain adequate documentation to support its depreciation expenses. It is simply not sufficient to say that a computer is taking care of the calculations automatically, without being able to provide the data which is being provided to the computer or to identify the particular assets and the basis for their historical costs. 39/ While it may well be true that some discrepancies resulted from recalculations performed by computer rather than from mathematical error, we conclude that NYSDSS has failed to meet its burden to demonstrate that that was so with regard to these 151 assets. Conclusion For the reasons explained above, we uphold the disallowance to the extent that it relates to the following costs: -- Interest costs on general State borrowing. -- Depreciation relating to assets which NYSDSS admitted had been transferred away from OMRDD's use. -- Depreciation relating to assets for which documentation adequate to permit identification and examination was not available. -- Abandonment loss on SIDC, transferred without cost for use as a public college campus, subject to HCFA's discretion to consider a request for retroactive approval. -- Excess depreciation because of the failure to assign a ten percent salvage value to fixed assets. -- Mathematical errors in the calculation of depreciation on some assets. We reverse the disallowance to the extent that it relates to the following costs: -- Design costs arising in FY 1976-77 but not yet fully amortized in FY 1986-87 due to a one year time lag in effect for claiming depreciation on assets acquired at that time. We remand the following portions of the disallowance: -- Depreciation costs relating to seven assets for which the date of transfer was not determined, so that NYSDSS may provide additional documentation and HCFA may make a determination as to the correct dates of transfer. -- Depreciation costs relating to one asset which was replaced, so that NYSDSS may provide additional documentation and HCFA may make a determination as to the method of disposal of this asset and the consequent depreciation adjustment. -- Excess depreciation because of the failure to assign any salvage value to moveable assets, so that HCFA can recalculate the amount of the disallowance using an assigned salvage value of five percent for these assets. -- Design costs amortized over too short a period, so that NYSDSS may provide evidence regarding the useful lives of renovated buildings and may seek agreement with HCFA on a reasonable estimate for the amortization period. In regard to those portions of the disallowance remanded to HCFA, NYSDSS should submit any additional documentation (where appropriate) to HCFA within 30 days of this decision, or such additional time as HCFA may permit. NYSDSS may appeal to the Board on the remanded items only within 30 days of receiving HCFA's written determination. ___________________________ Cecilia Sparks Ford ___________________________ Norval D. (John) Settle ___________________________ M. Terry Johnson Presiding Board Member 1. NYSDSS contended that UKW's findings regarding interest costs were unauthorized, because UKW's contract with HCFA only called for a review of depreciation costs. NYSDSS Br. at 9, n.7. However, NYSDSS did not explain why the allowability of the interest costs would be affected even if UKW's review of costs extended beyond its contractual responsibility. Therefore, we make no determination as to the scope of UKW's contract with HCFA. 2. The amounts of the overstated costs reflect adjustments by UKW to allow for OMRDD's inactive space adjustment and a stepdown calculation for capital cost rates, which are discussed in this decision only when relevant to disputed issues. See generally NYSDSS Ex. 1, at internal exhibit E. 3. In citing the PRM, we give the date of the most recent version of each provision. The parties pointed to no instance in which the version in effect at the period in question differed in any material way. 4. The context of this provision in the PRM makes it even more unlikely that normal operating expenses could have been intended to encompass state-wide governmental costs. The PRM generally requires that interest costs be supported by loan contracts. Where supporting records are maintained physically away from the facility (such as with a county treasurer for bond records) and the interest is otherwise allowable, the PRM permits the records to be deemed to be those of the facility where the bond issues "have been specifically designated for the construction and acquisition of your facilities." PRM,  202.1. NYSDSS acknowledged that the interest costs here failed to meet the requirement that interest be identifiable in the facilities' records. NYSDSS Br. at 19. NYSDSS contended TRANs interest was, in this regard, "no different from other indirect costs that are allocated to OMRDD and are reimbursable under" the state-wide CAP. However, as we discuss below, TRANs interest was not and could not be included in the state-wide CAP. We therefore find that the record-keeping restriction in the PRM on interest cost documentation supports our interpretation that the PRM did not intend borrowing for "normal operating expenses" to be read so expansively as to reach state-wide operations remote from specific facilities. 5. NYSDSS noted that the State plan limits interest on working capital indebtedness for certain facilities (those with less than 30 beds). NYSDSS Reply Br. at 9. NYSDSS contended that this limitation evidenced that the State plan would also have expressly excluded "indebtedness incurred by other agencies of the State on behalf of OMRDD" if such an exclusion were intended. Id. If anything, this limitation on facilities which can claim interest on working capital indebtedness demonstrates further that this cost element was envisioned as related to particular facilities and not as a pass-through of state-wide costs. 6. NYSDSS argued that State plans are not required to make detailed distinctions such as the relation of working capital indebtedness to State tax anticipation indebtedness, relying on our decision in South Dakota Dept. of Social Services, DAB No. 934, at 9 (1988). State Reply Br. at 10, n.3. The point here, though, is not that the State plan was flawed in its failure to specifically address tax anticipation indebtedness, but rather that the plan chose to refer to the PRM for all issues not specifically addressed in the plan itself. To refuse to turn to the PRM on this point would be to ignore the directive of the State plan. 7. The PRM has an analogous treatment of bonds to finance construction or acquisition of publicly-owned facilities, making a distinction between bonds directly issued to benefit a facility and the use of general government funds, even if obtained through issuance of bonds. PRM, Part 216 (January 1983). Where the funds to finance a public facility are obtained from general purpose government funds, even if "a portion of such fund is raised through bond issues, no part of the interest payable on the bonds is allowable as a cost of the provider." Id. at  216.2. 8. NYSDSS described the interest costs in various ways and later denied that they were indirect or overhead costs, subject to the plan limitations on such costs. NYSDSS Reply Br. at 17-19. NYSDSS did not explain how interest on borrowing by the State could be a direct cost of an ICF/MR, but argued that the allowance of interest on capital indebtedness, including working capital indebtedness, meant that "all interest, including interest on spring borrowing, is includible . . . even though it does not fall within the Plan's definition of `overhead cost,' and regardless of whether it is a direct or indirect cost." Id. at 18-19. Nothing in the plan supports this sweeping inclusion of the interest costs of every level of state government for any purpose whatever as costs of ICF/Mrs under the State plan. 9. NYSDSS did not object to the sampling methods used by UKW, and in fact asserted that its own statistical analysis duplicated UKW's methodology. NYSDSS's essential objection, which we address in the text, was that UKW treated all items which could not be located and examined as errors. 10. NYSDSS made no separate argument in regard to the two items in group (b) that were found not to be in use upon examination and therefore we affirm that portion of the disallowance without further discussion. 11. The amount of the overstated depreciation calculated by UKW was reduced to avoid duplication with the disallowance amount calculated for failure to assign salvage value. 12. The line items involved are as follows: Two line items listed by UKW as both lacking proper documentation and transferred (600037 and 600030), and challenged by NYSDSS, related to improvements to specific buildings at the Craig Developmental Center (Craig) which were transferred in 1984. A third line item (600020) was also not properly documented and was related to Craig, but could not be identified by building. NYSDSS Br., App. at 3-4. Another line item (600202) was found to be partially documented and located at Craig but not identified with a specific building. (Line items 600020 and 600202 are included here but since Craig was not completely closed until 1988, they could also have fallen under the category of items treated as still in use in the fiscal year had the buildings involved been identifiable.) Another line item (600183) was found adequately documented and identified with nine buildings at Craig which were transferred to other agencies between 1982 and 1984. 13. The line items involved are as follows: One line item (600041) was found to lack documentation but was identified with a building at Rome Developmental Center (Rome) which was transferred to another state agency in October 1987 and was therefore allegedly in use during the fiscal year in question. Another line item (600064) was found to have partial documentation and was identified with two buildings at Rome that were not transferred until October 1989. Id. at 5. Two line items (200277 and 600072) were adequately documented and related to specific facilities at Rome which NYSDSS asserted were not transferred until October 1987. Another line item (200556) was adequately documented and identified with a building at Rome which NYSDSS alleged was in use until 1989. Two line items (200082 and 300022) were found to be adequately documented and identified with a building at the Long Island Development Center (LIDC) which NYSDSS alleged was still in use in the fiscal year in question. 14. In fact, the standard also advises the auditor to consider whether the reasons that the items cannot be examined have implications for the auditor's "degree of reliance on management representations." Id. This advice militates against reliance on unsupported claims by management that items lacking documentation and not available for inspection are nevertheless properly in use. 15. Furthermore, the State plan does not allow the inclusion of any expenses "that are not reasonably related to the efficient and economical provision of care." NYSDSS Ex. 7, at 23. It is difficult to see how the relation of these expenses to the efficient and economical provision of care could be verified when the assets involved cannot be identified, located or examined. 16. HCFA attacked the validity of A&I's methodology on several other grounds as well. See HCFA Br. at 72-77; HCFA Supplemental Br. at 7-11. However, in light of our conclusion that statistical sampling could not be used for the purposes attempted by A&I here, it is not necessary for us to discuss further these disputes as to the validity of A&I's methodology. 17. NYSDSS claimed that HCFA was wrong to characterize this depreciation as "not documented at all," since the assets were "at least reflected in the ADR." NYSDSS Reply Br. at 73, n.34; see HCFA Br. at 71, n.30. It is academic whether the depreciation is characterized as insufficiently documented or wholly undocumented. The point is that NYSDSS could not establish from its records what the assets listed in the ADR were, where they were located, or whether they were being used for proper purposes. No statistical methods can remedy this omission. 18. The parties agreed that the relevant year for this element of the disallowance was FY 1988-1989, since the unrealized depreciation costs were claimed as a material change from the base year costs based on the transfer. 19. Both parties agreed that Medicare principles apply to the issue because no State plan provision was on point. See NYSDSS Br. at 34, n.22. 20. The method of including the loss depends on the size of the aggregate loss and the degree to which the asset was depreciated. See PRM,  132.A.3. 21. It is therefore not decisive that the Dormitory Authority has been found to have "separateness and juridical distinction" from the State for purposes of tort claims. Braun v. State, 117 N.Y.S.2d 601, 602 (N.Y.Ct.Cl. 1952). Nor is it significant that the Dormitory Authority may not be "identical" with the State for purposes of enforcing a contractual arbitration clause. Dormitory Auth. v. Span Electric Corp., 218 N.E.2d 693, 695 (N.Y.Ct.App. 1966). 22. HCFA conceded that actual title to the facility passed from the State of New York to the Dormitory Authority (which unlike OMRDD could hold title in its own name). HCFA Br. at 54. However, even after title passed, HCFA argued that the State itself did not relinquish all claim on the property since it retained a reversionary claim if the property ever ceased to be used for college purposes, as well as a utility easement. Id. at 54-55; NYSDSS Ex. 16, at 3-4. NYSDSS argued that these claims were irrelevant since the depreciable assets were the buildings, not the land through which the easement ran, and the reversionary claim was meaningless at least since so many of the assets involved were buildings which were demolished or renovations which were torn out. NYSDSS Reply Br. at 57-59. Since we have found that the State continued to exercise control through the Dormitory Authority as a related organization, the passing of title is not decisive. The reversionary claim simply demonstrates further that the State retained rights to control the use of the property. We discuss the effect of the demolition of the assets below. 23. In light of our conclusion that the Dormitory Authority is related to the State for these purposes, we need not distinguish between the period when SIDC was leased to it by OGS and the period after the deed was executed. Cf. NYSDSS Reply Br. at 55, 57, n.25. 24. Therefore, the discussion in this section would not apply to buildings or renovations which were not demolished or which continued to be used for any purpose. No loss can be claimed on these assets, since they are neither demolished nor abandoned for the reasons discussed above. 25. NYSDSS also argued that, even if approval was not obtained, the PRM provisions should not be read to apply strictly, since the State plan merely adopts the PRM as the "major determining factor" rather requiring absolute compliance with it. NYSDSS Reply Br. at 64, n.31. NYSDSS based its argument on language in the PRM provision requiring the approval request to be submitted to HCFA's Regional Office through the "intermediary," a role that exists in Medicare but not Medicaid. We conclude that the reasonable interpretation of the State plan's adoption of the PRM in the area of demolition is that the approval requirement applies but can be met by submission to HCFA directly. 26. Both parties agreed that the PRM applied to this issue because the State plan contained no provision regarding salvage value. See NYSDSS Br. at 22, n.13; HCFA Br. at 38, n.19. 27. By contrast, under HCFA's approach, Asset B would be treated in the same way as Asset A, since its anticipated value upon donation would be the same, even though the provider chose to avoid actually realizing that value by donating the asset rather than selling it. 28. NYSDSS did not explain why it included the transfer of SIDC to OGS and then to the Dormitory Authority as an inter-agency transfer here, while denying that it constituted an intergovernmental transfer in regard to OMRDD's claim of abandonment. Cf. NYSDSS Br. at 50, n.21. Furthermore, the fact that CUNY demolished or gutted most of the buildings at SIDC does not demonstrate that they were not expected to have any salvage value at the end of their useful lives. As also discussed in relation to the abandonment issue, these assets were never offered for sale in arm's-length transactions to parties who might have been able to put them to use in a way which CUNY was not. Further, it strains credulity to assert that, even as building shells or components, these assets could not have been expected to generate some salvage value. 29. HCFA also suggested that the appropriate salvage value would be the fair market value of the assets upon disposal or transfer, which could be ascertained by independent appraisers. HCFA Br. at 45-46. NYSDSS rejected this alternative approach, arguing that OMRDD does not expect to realize revenue upon transfer of the buildings or to sell them for fair market value. NYSDSS Reply Br. at 48. 30. NYSDSS also claimed that this fact meant that OMRDD itself did not receive any revenue from the sales. However, any income which the State received from sale of assets acquired through operation of facilities with Medicaid funding would be attributable to determining whether the facilities overstated the depreciation of those assets in setting their reimbursement rates, regardless of the account in which the State deposited the revenues. 31. HCFA also argued that the survey was flawed in covering only assets disposed of in one year and only a small portion of OMRDD's total depreciable assets. We fail to see the relevance of these points since the actual salvage value of assets is determinable only upon disposal, not during use, and the base year would seem to be a reasonable time frame in which to examine this. 32. Thus, while an independent appraisal might be necessary, as HCFA suggested, to determine the salvage value of transferred assets, no such approach is needed where a bona fide sale or scrapping has occurred. See generally PRM,  132. 33. Under the PRM provisions, however, depreciation is adjusted upon disposal to reflect the actual value realized (gain or loss), if the asset is disposed of by the methods permitted by the PRM. Therefore, assets which are disposed of by bona fide sale, scrapping (for personal property), demolition or abandonment (if replaced or approved as required), or involuntary conversion for less than the assigned salvage value would be recalculated at the time of disposal. No gain or loss may be realized on donations, trade-ins or exchanges. See PRM,  132; HCFA Br. at 39-41. Therefore, NYSDSS would recover any loss resulting from too high an estimate of salvage value upon a bona fide disposal, but would not be entitled to assume in advance a zero value across-the-board. 34. Neither party suggested undertaking such an effort as an alternative. 35. NYSDSS admitted in its reply that moveable assets were assigned salvage values in the Blake report, but insisted that no salvage value was assigned for category 1, 2 and 3 fixed assets. NYSDSS Reply Br. at 45. The Blake report excerpts in the record for Letchworth Village (SIDC) fixed assets do not show any figure for salvage value. Cf. NYSDSS Ex. 8. HCFA did not submit any other excerpt showing any salvage value entry for category 1, 2 and 3 fixed assets, although HCFA did provide cover sheets from the Blake report which state that the appraisal program included determining a salvage value for each asset. Cf. HCFA Ex. 4, at 2, 10. HCFA also provided excerpts relating to moveable assets which do show salvage value figures. HCFA Ex. 5. We therefore refer to the Blake report in relation to moveable assets but not fixed assets. 36. As discussed in the preceding section, NYSDSS conceded that the design costs should have been amortized over a longer period and therefore did not dispute $352,904 of the overstated design costs. NYSDSS asserted that this adjustment also reflected adjusting the design costs from FY 1977-78 to the 20-year amortization schedule suggested by NYSDSS. NYSDSS Br. at 48, 50. UKW, on the other hand, reduced the amount which it included as overstated under this element to avoid duplication with its recommendation that all design cost claims be amortized over 40 years. Since we accept neither parties' figure, it will be necessary to adjust the figures to reflect the amortization period determined after remand. 37. NYSDSS asserted that, beginning in FY 1983-84, the lag was eliminated for category 6 assets (major fixed assets purchased by the FDC) and was reduced to six months for category 7 and 8 assets (equipment purchases charged to FDC or directly to facilities). NYSDSS Br. at 49. 38. NYSDSS described a hypothetical example of an asset entered into the system with an initial price of $10,000 and a useful life of 20 years, resulting in an annual straight-line depreciation expense of $500. After the first year of depreciation is claimed, the price was adjusted to $11,000 after litigation, raising the annual depreciation expense to $550. The first year's depreciation was too low by $50. Therefore, the depreciation expense for the second year would be included as $600, while the depreciation expense for the third and following years would be $550. NYSDSS argued that adjustments of this kind caused the discrepancies which UKW attributed to mathematical error. NYSDSS Br. at 51-52. 39. This element differs from the time lag discussed above, in that the time lag for depreciating newly-acquired assets was applied across-the-board to all assets, so that individual documentation was less important. The assertion that particular discrepancies may have resulted from changes in historical cost due to contract renegotiations or litigation, by contrast, would require substantiation that such events had occurred and had had the purported effect on the depreciation costs of individual
