Thanks, Rodney. So I guess I would characterize the first quarter as a continuation of a very eventful 2012 in which we reported encouraging results of our Phase I PMD trial, clinical data from our Phase I/II spinal cord injury trial and preclinical data for AMD and Alzheimer's disease. So first, let me summarize the results of our clinical trial for PMD. This is a rare leukodystrophy that's characterized by imperfect growth of the myelin sheath surrounding nerve fibers in the brain. Firstly, evidence of progressive and durable donor-derived myelin in all 4 patients transplanted with the cells. Gains in motor and/or cognitive function in 3 of the 4 patients, while the fourth patient remained clinically stable. Now given the natural history of the disease, the gains observed in neurological function were unexpected and they provide the first demonstration of a biological effect of our cells in humans. As I've previously stated, each patient has been enrolled in a separate 4-year observation study. So we will be in a position to provide additional information on their progress. And we plan to provide an update later this quarter on their status at the 2 year time point. We also plan to meet with the FDA to discuss possible pathways to registration and to obtain their feedback on our proposed design for a multi-center Phase II study. Second, with respect to spinal cord injury. We announced in September, interim 6 months data from the first patient cohort which showed multi-segment gains in sensory function in 2 of the 3 patients. Now given that these were patients who's injuries were classified as complete injuries, the gains observed were unexpected. In February of this year, at the BIO CEO & Investor Conference in New York, we announced that the first patient cohort had completed the trial and that the multi-segmental gains in sensory function, first observed at the 6 month time point, had persisted to the 12-month time point. In addition to that, we also announced that one of the 2 patients have converted from a complete injury to an incomplete injury, i.e., from an ASIA A to an ASIA B classification. Third, in January of last year, we published the preclinical data that underlaid the IND for our ongoing Phase I/II trial in dry AMD, which showed that the HuCNS-SC cells preserve vision in animals that would otherwise go blind. To date, we have dosed 3 patients at the Retina Foundation of the Southwest in Dallas in Texas. And we expect enrollment to accelerate now that we have added a second study site at the Byers Eye Institute at Stanford. And we're also continuing to work at adding more sites for this trial. Fourth, in July of last year, we presented preclinical data demonstrating that our cells restored memory in 2 animal models with relevance to Alzheimer's disease, would suggest our neural stem cells may represent a novel therapeutic approach for memory enhancement. As Rodney has already mentioned, in April of this year, we entered into an agreement with CIRM for a $19.3 million forgivable loan to help fund our preclinical and IND-enabling activities for Alzheimer's. So in summary, with regards to the clinical data and progress to date, while still too early to be definitive, the clinical data that's emerging from Batten's trial, the PMD study and the spinal cord injury trials, are starting to confirm the exciting results that we have previously reported in the various animal models. So this gives us confidence that we're on the right track. So our focus now is on accelerating patient enrollment in our ongoing trials and then to report out the data. So before finishing up, I just want to mention that on the last call, I indicated that we will be able to provide some color behind our decision-making process regarding the CIRM awards. So specifically, you will recall that we declined CIRM funding for our cervical spinal cord injury program, but accepted it for Alzheimer's disease. As you probably know, when CIRM offers to fund a program, they essentially share some of the risks and rewards with the company. So if a CIRM funded program turns out to be commercially successful, the awardee is obligated to pay CIRM what they call risk premium payments, which are essentially success milestones. So in the case of StemCells Inc. these payments will be payable only if HuCNS-SC cells were successful for the relevant indication, example, in Alzheimer's disease or spinal cord injury. But in any case, would be capped at 5x the loan principal or $200 million, if we borrowed the $40 million for both programs. So given the huge market potential for an effective therapeutic for memory enhancement on Alzheimer's, we were happy with the prospect of paying the risk premium payments if we were successful. Conversely, if we were not successful, we would not have to repay the loan. CIRM funding, therefore, for Alzheimer's disease is a free option and given the high-risk, high-reward nature of pursuing therapeutics for Alzheimer's disease, on balance, accepting the CIRM loan is a good deal for our shareholders. We arrived at a different conclusion, however, for cervical spinal cord injury due to the very different risk reward profile associated with that program. So for starters, the potential market for spinal cord injury is considerably smaller than for Alzheimer's disease, but the risk premium payments required by CIRM were the same multiples. Moreover, we were already well underway with our spinal cord injury program and had an actively enrolling Phase I study in Switzerland generating encouraging clinical data, albeit, in thoracic spinal cord injury. CIRM, however, indicated to us that it expected to expand obligations under the loan to our entire spinal cord injury program, not just for cervical injuries. So in our view, it was not on our stockholders' best interest to become obligated for potential risk premium payments based on the success of our entire spinal cord injury program in order to borrow money from CIRM to help fund preclinical studies in cervical spinal cord injury, particularly, since to date, we have self-funded and bourne all the risk of our spinal cord injury program. So for these financial and programmatic reasons, we decided the Alzheimer's loan was in our stockholders' best interest, but that the cervical spinal cord injury loan was not. So I thank you for your attention, and we'll now open the call up for questions.
