OPINION
I. INTRODUCTION
This case is before us for the second time. In Williams v. Crawford, we remanded with instructions that Camille Williams be awarded "one-half of the value of the marital portion of [William MeVey'sl civil service pension-valued as of the date the parties entered into the property settlement agreement, August 12, 1992" 1 On remand, the superior court awarded Camille one-half of the marital share of the pension benefits that William, who died in June 1995, had actually received. Because this award turned on information-the actual date of William's death-not available on August 12, 1992, when the parties entered into their agreement, we vacate the award and remand for further proceedings.
IL FACTS AND PROCEEDINGS
Camille Williams and William McVey divoreed in April 1992. Camille remarried shortly thereafter. 2
On August 12, 1992 Camille and William entered into a property settlement agreement, which the superior court incorporated into the divorce decree. 3 Paragraph Seven of the agreement stated:
[William] shall be granted all payments under his Civil Service pension during his lifetime. [Camille] shall be granted surviv-orship benefits upon [William]'s death equal to one-third the maximum survivor-ship benefits that may be elected, which means that [Camille] shall receive surviv-orship benefits at [William's] death of at least $6,912 per year, or $576 per month. [William] shall elect survivor benefits and shall be responsible for any required premiums or cost to insure [Camille]'s surviv-orship benefits. This Court shall retain jurisdiction as necessary to enforce these provisions.[ 4 ]
When William retired two years later, he discovered that federal regulations made Camille ineligible for survivorship benefits, because she had remarried before age fifty-five. 5 Both parties were unaware of this restriction when they entered into the agreement in 1992. 6 Camille therefore moved under Alaska Civil Rule 60(b)(6) to be named the irrevocable beneficiary of William's life insurance policies. 7 The superior court granted Camille's motion. 8 Before comply ing with the superior court's order, William unexpectedly died in June 1995. 9
After a series of superior court proceedings, 10 Camille appealed to us. Because Camille's "eligibility for the survivorship benefits was one of the fundamental assumptions underlying the property division," we held that Camille was entitled to Rule 60(b)(6) relief. 11 We concluded that
Camille should receive one-half of the value of the marital portion of William's civil service pension-valued as of the date the parties entered into the property settlement agreement, August 12, 1992. This is the most equitable result given the particular facts of this case. We remand this valuation question to the superior court for determination.[ 12 ]
On remand, Camille argued that our remand instructions to award Camille "one-
By contrast, the estate argued on remand that the superior court should value William's pension by simply totaling the pension benefits William received-$58,567-before he died in June 1995. 13 Based on this calculation, the estate valued Camille's share of the pension at $10,700.19.
The superior court agreed with the estate. Its July 18, 2000 order concluded:
Because this court understands that Camille is entitled to equitable relief, and because the estate's method of valuation is the one which results in a figure most closely resembling the value of an asset that she knowingly bargained for with the assistance of counsel, this court finds that equity demands adoption of the estate's valuation method. This court further finds that adoption of Camille's valuation method would be profoundly and manifestly inequitable.
On July 19, 2000 the superior court denied Camille's motion to vacate the attorney's fees and costs awards it had entered against Camille before we issued our 1999 opinion.
On July 28, 2000 Camille filed a petition for review asking us to review the superior court's July 2000 orders. The estate did not oppose the petition. We granted Camille's petition for review on September 28, 2000, and ordered briefing. 14
III. DISCUSSION
A. Standard of Review
"Upon remand of a case by this court it becomes the duty of the lower court to obey the mandate and render judgment in conformity." 15 Whether a lower court on remand has correctly applied our mandate 's a question of law which we review de novo. 16
B. William's Pension Was Erronecously Valued on Remand.
Camille argues that it was error to value William's pension by considering information that was not available on August 12, 1992, the date we instructed the superior court to use in valuing William's pension. Camille notes that on that date, it would have been impossible to determine the amount of pension benefits William would collect before his eventual death. Thus, Camille argues that the superior court should have valued the pension by multiplying William's life ex-pectaney as of August 1992 by the expected annual pension benefit, adjusting that figure for cost of living allowances, and discounting it to present value.
The estate responds that our remand instructions in Williams required the superior court to award Camille the amount she would have received if the court had divided Willam's pension in August 1992. Citing
Camille's interpretation of our remand instructions is correct. We instructed the superior court to award Camille one-half of the marital share of William's pension valued as of August 12, 1992, when the parties entered into their agreement. We have previously referred to the value of a defined benefit pension 21 as its actuarial value, determined by multiplying the employee's life expectancy by the expected annual benefit, and discounting it to present value. 22 It is appropriate to apply this same valuation method here. We specified August 12, 1992 as the date of valuation, because we intended to give effect to the parties' agreement to divide the pension benefit as of that date. We did not intend that the value of William's pension would be calculated based on the actual date of his death, a date that was, of course, unknown to the parties on August 12, 1992 when they entered into their agreement.
We therefore conclude that it was error to rely on remand on the actual date of William's death in valuing the pension. Accordingly, we reverse and remand for further proceedings.
On remand, the superior court should determine the actuarial value of William's pension on August 12, 1992 by multiplying William's life expectancy on that date by the expected annual pension benefit, and by discounting to present value. In calculating that value and determining William's life ex-pectaney as of August 12, 1992, however, the superior court may consider evidence relevant to the state of William's health to the extent it bears on his life expectancy and to the extent it was known on August 12, 1992. 23
The superior court concluded on remand that it would be inequitable to ignore the amount actually paid on William's pension, an amount dependent on the actual date of his death.
We disagree with that conclusion, for a number of reasons. First, looking to Wil
Second, basing the award on the actual date of death leads to inequity not recognized by the superior court. Its conclusion of inequity turns in part on its finding that Camilie "knowingly bargained ... with the assistance of counsel" for a nearly equal division of the pension benefit. But to be consistent, if the actual date of death can be taken into account for one purpose, it must also be taken into account for equivalent purposes. Per the superior court's analysis, the values of what the parties respectively bargained for would have to be based on the actual date of death. Knowledge in August 1992 that William would die in 1995 would have made the survivor benefit bargained for by Camille more valuable and would have diminished the value of the benefit bargained for by William. Inconsistent use of the prospective date of 'death contributed to the inequity perceived by the superior court.
Finally, the superior court does not mention another post-agreement cireumstance that bears on the equity resulting from our prior remand instruction. After the parties learned of Camille's ineligibility for survivor-ship benefits, Superior Court Judge Larry D. Card granted Camille post-judgment relief and ordered William to make Camille the beneficiary of his life insurance policies. William died before complying.
C. Denial of Camille's Motion to Vacate Awards of Fees and Costs Was Error.
We also hold that it was an abuse of discretion to deny Camille's post-remand motion to vacate the July 1997 awards of attorney's fees and costs. Those awards were based on the March 1997 order that denied Rule 60(b)(6) relief to Camille. When we reversed the March 1997 order in 1999 and remanded to determine the value of the pension as of August 12, 1992, the July 1997 fees and costs awards should have been vacated as a matter of course. 24
IV. CONCLUSION
For these reasons, we VACATE the July 18, 2000 decision and order valuing William McVey's pension and the July 19, 2000 order denying Camille's motion to vacate the attorney's fees and costs awards. We REMAND for further proceedings consistent with this opinion.

Because William's contributions to the retirement fund totaled $58,567, an amount greater than the total amount of benefits William received, the estate conceded that William's pension should be valued at $58,567 to account for the lump sum death payment received by Wil-Ham's estate.
